Detailed description of the invention

Detailed description of the invention set forth below combines accompanying drawing and is intended to describe currently preferred embodiment of the invention, and not Being intended to mean that can be with structure or the unique form utilizing the present invention.Described embodiment combines the embodiment described and proposes For constructing and operate function and the order of the step of the present invention.It should be understood, however, that can also be come real by different embodiments Function that is the most identical or that be equal to and order, described different embodiment is also contained in the spirit and scope of the present invention.

In order to improve the ability that the exact dose of the medicine to vapor form measures, enter for from steam delivery device Row sucks, and steam delivery device is required to heat and the control of the power of persistent period controlling to apply the medicine to liquid form System, or can accurately, as one man and repeatably discharge the fluid delivery system of the medicine of precise volumes.These are two years old Kind of method: (a) controls to be applied to the heat of liquid, and (b) controls liquid volume to be evaporated, can be used alone or It is applied in combination to improve the accuracy of the medicine " dosage " that vaporizer provides.As used by detail in the claims, term " medicine " refer to a kind of medicament, medicine, oral medicine, patent medicine, medicine and for healing, treat, change, improving, extensive Again, alleviating and/or cure specific symptoms, disease or spirit or the analog of health, it includes being injected into expedient method In or the combination that is dissolved in the active component in some other carriers or active component and non-active ingredient.

The heat applied is relevant to the quantity of power being fed to steam delivery device with the persistent period.Therefore, in order to improve current steaming The function of vapour conveyer device, present apparatus must implement with power control system, and described power control system comprises a kind of structure Part, described component for providing the accurate power amount that power supply produces, with by heating element heats to the liquid that can make predetermined It is minimum temperature required that body evaporates completely.Characteristic based on medicine, the most expedient method or carrier, can calculate and send as an envoy to Predetermined evaporates required minimum temperature completely.By understanding the minimum temperature needed for evaporating the medicine of predetermined, permissible Energy resource is saved by not using more than the energy of necessary amount, and one of this problem that existing apparatus exists just.

For providing accurate power amount that power supply produces to be steamed completely to the liquid that can make predetermined by heating element heats Sending out required minimum temperature required component and comprise control circuit or integrated circuit 82, described circuit has being sent to heating The processor 500 that the power of element 152 is controlled, to guarantee the power only the providing necessary size designated volume to release It is evaporated.It is associated to by the resistance of heating element heater, therefore owing to being fed to the watt level of heating element heater 152 Can be programmed monitoring the resistance value of heating element heater 152 to processor 500 thus indirectly know as being fed to heating unit The representative of the quantity of power of part 152 monitors the resistance of heating element heater 152.Know that known value, processor 500 can be managed Reason is fed to the quantity of power of heating element heater 152.At heating element heater, measure resistance there is some advantages.It is possible, firstly, to accurately Ground is measured and keeps power measure power accurately and keep.Secondly, can from the voltage of circuit measuring gained, and Not being from battery measurement voltage, this can extend battery life.3rd, it ensure evaporation and keep constant, so that nothing The life cycle of opinion battery and the degraded what state of heating element heater, can measure dosage.

In certain embodiments, for providing the component of accurate power amount can also comprise as switching DC/DC transducer Boost converter, and ultracapacitor 368a, 368b.Described boost converter uses and H bridge and inductor/capacitor The charging converter that device system one works.By use boost converter, can limit charging current with protection battery and Allow super capacitor produce the persistent period shorter bigger discharge current.Only illustrating, it may need 3 to 5 seconds Charge, but only need discharge for 0.5 second.Therefore, battery may only observe the load of 100-200mA, but electric capacity Device can observe 1A or more load.By utilizing this system, it is possible to use alkaline battery 364, thus improve The safety of this device.

Ultracapacitor (" supercap ") 368a, 368b are the electrochemical capacitors with of a relatively high energy density. Its energy density is typically larger than the hundreds of times of traditional electrolyte capacitors.The electric capacity that ultracapacitor 368a, 368b can store Up to two orders of magnitude of standard electrolytic capacitor storage capacitors.

The Circuits System of the present invention use DC/DC boost converter from one group of alkaline battery 364 to ultracapacitor 368a, 368b is charged.When ultracapacitor 368a, 368b are charged, it is necessary to consider multiple parameter.For explanation Purpose, it is possible to use one, by the Capacitor banks of be charged to 6V DC 300 farads, uses and can generate 1.2A The 6V power supply (4-1.5V AA battery) of MAX electric current.Note to use a resistor in this circuit arrangement, with by electricity Stream is restricted to maximum amperage, such as, 1A etc., as the extra control of heater circuit.

In order to how the charging circuit system of the present invention is worked it is defined, uses ohmic law of equation, charging resistor value =6V/1A=6 ohm.This uses Ohm's law to determine: R=E/I, wherein R is the resistance with ohms, and E is The energy represented with volt, and I is the electric current represented with ampere.

In order to determine, Capacitor banks is charged required electricity, utilize " power ", its being electrically described as " watt Number ".This power equation is described as:

Resistor power=6V x1A=6W(power=voltage x current)

Therefore, in order under 1A, the Capacitor banks of 6V is charged by power supply (4AA/AAA battery) with 6V, need The resistor of 6 ohm of 6W to be had or higher wattage rating.In some designs, less battery, such as one, Two, or three batteries may be used for supplying enough power.

Making in this way, the present invention solves the standard in the issue for battery life that Current electronic medicated cigarette (e-medicated cigarette) has Problem.Additionally, the method provides the ability maintaining sufficient power, to use standard alkaline type chemical cell to make liquid steam Send out, and current e-cigarette device cannot use standard alkaline type chemical cell.

Figure 36 show the block diagram of described process.Wherein there are energy source or the power supply 600 of supply input power.This power supply If can be the one in dry type, but it generally be suitable for two types.Class1 can be a kind of lower wattage power supply, its nothing Method makes higher electric current on-line operation.Such power supply needs extra regulation to support whole functions, it is therefore desirable to Power conversion module 602 and power storage module 608.Type 2 can be high current source, and it allows the straight of evaporation element Connect driving.

State or control logic 604 provide control, measure and drive function, described logic can be special logic or Processor.One embodiment can use Texas Instrument's MSP430 processor (Texas Instrument MSP430 Processor), but it can also be any processor or the device of similar ASIC.GPIO and A/D can also be used Function is to allow electric current (directly driving) or to measure the voltage of power storage (ultracapacitor).When meeting During all conditions, control logic 604 and activate discharge switch 610, so that evaporation element 612 to be heated.

The ability that the power providing energy to evaporation element 612 is accurately measured and measured makes it possible to steam phase transition Measure accurately with dosage.In Direct Driving System, the electric current of driving and time are used for calculating and measuring heating evaporation Energy used by element 612.In storing energy system, formula 1/2CV²Energy in calculating system and required Terminal voltage, with metering for the energy of heating evaporation element 612, wherein C is electric capacity and V is voltage.

When power supply starts to exhaust, a kind of replacement scheme controlling quantity of power is to control the accumulation of energy time of heating element heater.Processor 500 Monitored resistance can be configured to and regulate the time that heating element heater stays open, so that the medicine of given volume steams completely Send out.

In certain embodiments, what flow switch 614 may be used for being asked evaporation stage is actuated for induction of signal.When When implementing in vaporising device, described device can have fluid delivery system (being discussed below).Described fluid delivery system Unite and before flow switch 614 activates, the desired amount of fluid is seated on evaporation element 612.

In certain embodiments, fluid release actuator 616 may be used for " waking up up " processor 604 and is super capacitor Device 608 charges 606(in storing energy system).In Direct Driving System, fluid release actuator may be used for from super Low-power sleep mode " wakes up up " processor 604.Fluid release actuator 616 could be for the machinery of activation system Device, such as, rotary switch, button, knob, action bars and the like.

In certain embodiments, diode 618,620 may be used for the state indicating system to operate to operator.Such as, One diode can be LED618 carries out induction of signal so that when evaporation element 612 is obtained driving.Another LED 620 may be used for flashing specific pattern to indicate system status, such as, power on, low battery electric quantity, the flow-like of consumption State, or other system particular condition state (that is, the maximal dose etc. of time per unit).In other embodiments, aobvious Show device, such as, LCD screen, it is displayed for system status or other information, such as, is included in conveyer device Material or drug type, remaining amount and/or dosage, battery charge level, user ID under device loss situation Deng.Button or similar device may be used for being activated by display and rolling.

In Class1 configuration (low current, alkaline battery etc.), charging current is restricted to maintain the life cycle of battery. In many batteries, if producing substantial amounts of electric current, then battery life or charged state will be significantly reduced.Therefore, The reduced-current generated from battery and power storage module 608 is used to can allow for the situation of high electric current, without exceedingly Exhaust battery.

In type 2 configures, if desired, power storage 608 may be used for extending battery (lighium polymer, lithium ion) Life-span.Power storage 608 can also utilize the simple voltage measurement energy to entering in evaporation element 612 more easily The exact magnitude of amount measures the most accurately.Accurately measuring the precise volume of the energy entered in evaporation element can To be completed by voltage and current measurement, but compared with measuring voltage, this method is difficult to accurately measure electric current.Cause This, it is advantageous to use the better simply process only measuring voltage.

Another feature saving power is to control logic 604 to share with power conversion 602, i.e. system (during energising) Power rating.The power saving feature of this power rating can be broken by the ultra low-power mode of conversion/cpu or power Opening/closing lock function realizes.This is for the operation lifetime of extension fixture after first use.

The liquid making predetermined evaporates required energy completely to be changed with quantity of power and the persistent period of power existence.Cause This, power control system 306 can also comprise the component for controlling the accurate persistent period, to provide in required temperature Under make the liquid of predetermined evaporate required accurate power completely.For the exact duration of supply power is controlled The component of system can comprise " one shot " control circuit system 170,172 or 174, and described Circuits System can be with institute above State the circuit integrating for controlling quantity of power.The example of " one shot " circuit 170,172 or 174 is at Figure 15 to Figure 17 Shown in, and will be described below." one shot " circuit may be used for limiting current feed time interval System, regardless of whether user by action bars downwardly against how long.Power control system 306 is " to close completely between using every time Close "；So not discharging at idle period battery.Therefore, the life-span of battery is extended.

In certain embodiments, integrated circuit can be configured so that the predetermined number of times of power initiation.This number should be of a sufficiently low, Make to start every time and all produce identical quantity of power.In certain embodiments, integrated circuit can be configured to monitor the battery longevity Order and do not start power when the battery life of scheduled volume being detected.

This power control system 306 can be implemented in existing steam delivery device.Such as, control system 306 is permissible It is installed in the handle of current steam delivery device, to implement together with existing heating system, thus improves present apparatus Energy efficiency and the accuracy of dosage.

It addition, or in addition, it is being controlled being significantly improved in terms of vaporising device to quantity of power size and persistent period While the amount efficiency of exact dose and effectiveness or in addition, a kind of for the precise volumes to the liquid that will evaporate The component as one man carrying out measuring may be used for producing that substitute or extra degree of accuracy.Therefore, efficient medicine is defeated Device is sent to comprise: to utilize the power control system 34 of the multinomial embodiment of Circuits System mentioned above, to control power Efficiently and effectively use；And/or fluid delivery system 30,302 or 402, described system is store as to from fluid The precise volumes of the liquid in storage consistently measures the structure of the volume accurately to control the discharge liquid for evaporation Part.The various combination of these systems may be used for obtaining desired accuracy level.It is likely to need atomization or vapo(u)rization system 32 evaporate medicine.In this application, it is atomized and evaporates and be suitable for interchangeably to be designated as can being sucked by pulmonary and absorb Form.

Can calculate at given temperature and the precise volumes that exposes the liquid that can evaporate completely under the persistent period.Due to The persistent period of the temperature of wire and wire energising can be fixing, therefore can predefine needs from fluid delivery system The precise volumes of release in system.Or, in certain embodiments, accurate volume can be according to the temperature of wire and this temperature Conduction time of lower wire and change.

The embodiment of power control system mentioned above provides by carrying out the given dose of medicine based on more accurately The advantageous manner of amount.The injection volume of release is controlled also improving the accuracy of metering.Described hereafter is for right The example of the device that the volume of the arrival heating element heater medicine to be evaporated is controlled.These devices can be used alone or Person is used together with power control system, to improve the accuracy of the dosing of medicine further.

In one embodiment, as depicted in figs. 1 and 2, delivery device 20 has an elongated shell 22, described outside Shell has is difficult to articulate 24 and action bars 28, described in be difficult to articulate and the back of action bars adjacent housings or top.It is difficult to articulate opening 26 Extend to be difficult to articulate in 24.With further reference to Fig. 3 to Fig. 5, an embodiment of device 20 includes: fluid or liquid conveying System 30, described system is as one man measuring the precise volumes of liquid accurately to control the releasing liquid for evaporation The component of volume；And vapo(u)rization system 32 and electric power control system 34.Electric power control system 34 can include being positioned at Battery 44 in the battery chamber 42 of shell 22, and wherein battery is electrically connected to flexible circuit by spring 46 and contact 48 Plate 82.As it is shown in figure 5, described shell can have left side and the right side of clam shell design.Action bars 28 can be at pivot Shell 22 it is attached at 58.

As shown in Figure 4, a kind of for the precise volumes of the liquid from fluid reservoir is as one man measured with to discharge The component being accurately controlled for the volume of the liquid of evaporation can be realized by liquid conveying system 30, shown Example in, described system includes elasticity or the liquid chamber of wall of bending or reservoir 64, described liquid chamber or reservoir It is connected to operate stem valve 70 by pipe 66.The thin wall flexible capsule that reservoir 64 can be made up of polyethylene film.Reservoir 64 are placed between two rigid surfaces, and wherein plate 62 is positioned at the inwall of shell 22 on side and is positioned on opposite side.Shell Plate 62 is pressed by the spring 60 in 22, and then presses reservoir 64.Thus to the liquid in reservoir Pressurization.

Pipe 66 from reservoir 64 extend to operate stem valve 70, described valve can include valve pillar 74, valve spring 72 and Valve spacer 76.In this design, the valve portion 80 of pipe 66 extends through the opening of valve pillar 74, as shown in Figure 6. Valve spring 72 is against the valve portion 80 propulsion valve pad 76 of pipe, so that described pipeline clamps and closes.

With reference to Fig. 4 to Fig. 6, an embodiment of vapo(u)rization system 32 includes the heating being electrically connected to electric power control system 34 Device 150.Vapo(u)rization system 32 is also connected to liquid conveying system 30 and receives liquid from liquid conveying system 30.Heater 150 can be the resistance heater formed by open coils 152 such as nichrome wires.In this design, electric current passes through adapter 156 Being fed to coil 152, described adapter is positioned on flexible PCB 82 or is connected to flexible PCB 82, described flexibility Circuit board is subsequently connected to battery 44.Figure 14 shows the adapter 156 for supplying electric power to heating element heater.

Operation stem valve 70 outside towards device be difficult to articulate or the exit zone 154 of pipe 66 that back end extends is inserted into coil In the front end of 152.At once with reference to Figure 14, solid electric wire insert 159 is inserted into coil 152 and exit zone 154 End in provide internal support so that when pressing down in adapter 156, they will not deform or collapse Collapse.Along with each startup of device 20, it is positioned at the exit zone 154 at winding heater 152 front end and provides the liquid into In coil hole.

Pipe 66 is connected to reservoir 64 by liquid-tight connection, and therefore liquid is only capable of being flowed out from reservoir by pipe 66. Pipe 66 can be resilient flexible material so that its inner chamber can be generally completely flat when by compressing, and And the most generally it is completely recovered to its original shape.The action bars section 67 of pipe 66 is positioned at action bars 28 And the lower section of the fixing rigid surface of enclosure, described action bars section alternatively can be as the one of circuit board 82 Point, power management circuitry is positioned on described circuit board.Can be in circuit board 82, on circuit board 82 or through electricity Road plate 82 provides location feature 112, to guarantee that required location is maintained.Action bars 28 is solid by action bars pivot 116 Hold, and can be pivoted by the range of movement that is controlled.

In use, being difficult to articulate 24 is placed in mouth, and action bars 28 is pressed or extrudes by user.Manufacturing Period, pipe 66 is pre-charged with or is filled with liquid.With reference to Fig. 4, along with action bars 28 pivots downwards around pivot 58, Pliers 86 clamps the action bars section 67 of pipe 66 against the inner surface of shell 20, neighbouring pivot 58 and reservoir 64. This is temporary close pipe 66 at pliers 86.Along with action bars 28 continues downwards (or inside towards the center line of device) pivot Turn, the ramped surfaces 88 of the action bars 28 little by little action bars district of extruded tube 66 between pliers 86 and operation stem valve 70 Section 67.This results in a kind of movement extruding type, so that pumping liquid with creeping effect towards operation stem valve 70.With Action bars 28 to continue inwardly to pivot, the power of the pillar antagonism valve spring 72 on action bars presses down on valve spacer 76. Operation stem valve 70 is so temporarily opened by making the valve portion 80 of pipe 66 open.Valve portion along with pipe The unlatching of 80, and along with the liquid in pipe is pumped by ramped surfaces 88, substantial amounts of liquid flows through valve portion 80 And exit zone 154 and entering in coil 152.

The constant positive pressure that spring 60 is applied on reservoir 64 is to the liquid pressing in pipe 66.But, owing to pipe 66 is By pliers 86 clamped closed, so not having liquid to flow out from reservoir when pressing under action bars and operating when stem valve is opened. On the contrary, the liquid in the Already in pipe 66 between pliers 86 and action bars valve 70 provides a large amount of liquid measured Body, these liquid are uniformly delivered in coil.

Action bars 28 move down the switch 158 also making to be connected on circuit board 82 or be positioned on circuit board 82 Guan Bi.Electric current flows to coil 152 from battery 44 or other power supplys subsequently.The heating of coil makes liquid evaporate.? During operation, the temperature of the electric current and coil that are fed to coil can be adjusted by circuit board, this depend on liquid used, Required dosage and other factors.Only switch 158 when action bars 28 is pressed down and may be located at make position.This keeps away Exempt from unexpectedly coil to be heated.This is also delayed and heats coil until big quantity of fluid is moved by the pivot of action bars Dynamic and till being moved in coil, thus contribute to extending the life-span of battery.Such as, the most hereinafter " one shot " control circuit 170 described may be used for limiting current feed time interval, and no matter user will be grasped Make how long bar grips downwards.Between using, power supply is completely " closedown " every time.Do not put at idle period battery Electricity.Therefore, the life-span of battery is extended.

From this specification it is clear that, along with each startup of device 20, use linear peristaltic pumping effect Consistent, that fix, the biggest quantity of fluid are transported in vapo(u)rization system 32 by liquid conveying system 30.Liquid carries Reservoir 64 is sealed between starting by system 30 further by pliers 86 every time, the receiving material of reservoir is protected Hold under pressurised conditions, and the electrical power being transported to vapo(u)rization system 32 is controlled.Liquid conveying system makes through design Must be along with the use of liquid, air will not be incorporated in system.

The diameter of coil 152 and length define cylindrical volume in the inside diameter of coil, and it be enough to from liquid delivery system System captures the liquid dosages that single transports.The neighbouring wire loop of coil 152 can also position so that surface tension of liquid Liquid is retained in coil hole.This makes device 20 can use in any orientation, and this is because of no need of gravity will The liquid dosages of release is held in place.

The use of open coil provides further advantage, i.e. steam can generate anywhere along the length of coil And effusion, without negatively affecting the equilibrium vaporization of the big quantity of fluid in coil.Coil additionally provides for heat transfer relatively High surface area and making owing to accessory part to be added thermally-induced Minimal energy loss.

After answering electric power, the liquid in coil evaporates and through the gap coil.The size and dimension of coil can With through setting and being positioned in shell so that when user sucks on being difficult to articulate, the steam of generation can be carried Enter in the air stream sucked by device 20." suck " herein and refer to major general's steam be drawn in mouth.

Fig. 7 to Figure 13 shows the second device embodiment 100 that can be similar to device 20, but has following difference. In the device 100, for the precise volumes of the liquid from fluid reservoir as one man being measured with to for evaporation The component that the volume of discharge liquid is accurately controlled comprises foam pad 106, and described foam pad is compressed and is inserted into Between reservoir 64 and a rigid walls of shell.Attempted to recover its relaxation state by foam and be applied on reservoir 64 Compression stress is applied on reservoir by power, thus is maintained in reservoir by liquid under stress.Foam pad 106 can substitute Spring 60 shown in Fig. 4 uses.Reservoir can use the syringe with spring offset plunger to add alternatively Pressure.Any one in being designed by these, reservoir can be optionally designed as removable cylinder.

As shown in Figure 8, in the device 100, it is provided that the pliers 86 in operation stem valve 118(substituted device 20) with to pipe The front end of 66 is compressed, thus prevents liquid from flowing out from the reservoir of pressurization between using every time.Action bars valve 118 Can be the metallic sheet-form of impressing, it be welded to rigid circuit board 114, and described circuit board contains and controls system for power Same as above or the similar Circuits System of system 34.

Figure 10 to Figure 13 shows other features, and these features may be used for a kind of component, and this component is for from fluid The precise volumes of the liquid of reservoir as one man carries out measuring accurately to control the volume discharging liquid for evaporation System, specifically, is the pump action of liquid conveying system in device 100.When needing the steam of doses, make User will be difficult to articulate and be placed in mouth and suck, simultaneously the button 109 on pressing operation bar 110 so that action bars to Lower rotation (counterclockwise).Along with action bars 110 initially rotates as shown in Figure 10, action bars pinched protrusion portion 132 is right At clamping point 140, the pipe 66 of Guan Bi clamps or clamps, thus closes the liquid storage device of pressurization.Action bars 110 Continue rotate make action bars 110 have reduce thickness bending point 124 at bend, as shown in figure 11.So make While pipe 66 still remains closed at clamping point 140, action bars can the excess of stroke rotate, without crushing described pipe.

Chamber in the pump section 68 of pipe 66 is compressed by further rotating of action bars 110 subsequently.So can be from pump district Section 68 pumps liquid towards operation stem valve 118.This movement also makes the jut on action bars be moved, described action bars Push down on valve flange 120, so that operating stem valve 118 deflection and opening, and allow substantial amounts of fluid under pressure to move Move through described pipe and enter in vapo(u)rization system 32.Operation stem valve 118 shown in phantom in Figure 12, described operation Stem valve 118 downwards and deviate the lower surface of circuit board 114 to open described valve.Finally, at action bars stroke End, switch operating rod jut contact switch 158, thus by power delivery system open.
