Description

Heating atomized electronic cigarette using capacitor power supply

Technical field

The invention relates to an electronic cigarette with a heating atomization function, in particular to a heating atomized electronic cigarette which is powered by a capacitor.

Background technique

In recent years, the traditional smoking methods have become more and more common to the smokers themselves and the people around them. To this end, government agencies in many countries or regions have issued regulations that prohibit smoking in public. However, for smokers with cigarette dependence (or addiction), quitting smoking will be a very difficult and painful long-term process, and it is impossible to see it immediately.

In order to meet the need to quit smoking, various forms of cigarette substitutes have been introduced on the market, such as nicotine spray, nicotine syrup, nicotine patch, nicotine chewing gum, and electronic cigarettes that can atomize nicotine solution. Among them, the electronic cigarette can realize the effective atomization of the nicotine solution, thereby retaining the characteristics of the traditional smoking method of smoking smoke during the smoking process, and can satisfy the smoker's habit to a greater extent. In addition, the main component of smoke generated by electronic cigarettes is nicotine, which does not contain carcinogens that are harmful to human health such as tar. Therefore, e-cigarettes have been favored by consumers in recent years and are becoming a substitute for cigarettes, playing an increasingly important role in quitting smoking.

The existing technical solutions for electronic aerosolization mainly include two categories: heating atomization and ultrasonic atomization. The application model number is 03242914.2, the Chinese utility model patent entitled "A pen type micro steam generator", proposes a scheme for heating and atomizing liquid in a small cavity, which is implemented in conventional liquid and nicotine. The atomization of the solution can develop the function of transporting nicotine vapor to the nasal cavity, oral cavity and the like. Different from the heating atomization scheme, the Chinese invention patent entitled "Non-combustible electronic atomized cigarette" with the application number 03111173.4 proposes an ultrasonic atomization scheme, which is foggy with a household humidifier. The same principle. Due to its high atomization efficiency, ultrasonic atomization technology has been widely used in various atomization fields, such as humidifiers, sprayers, medical nebulizers, ultrasonic atomization therapeutic devices, ultrasonic atomizing inhalers, ultrasonic beauty. Instrument, aroma atomizer, etc. However, due to volume limitations, ultrasonic atomization on electronic cigarettes is quite difficult with the prior art. Fact In fact, because of this, almost no exception to the current electronic cigarette products on the market has adopted the heating atomization scheme, rather than the high-tech ultrasonic atomization claimed in the advertisement.

Although heat atomization has been successfully used in electronic cigarette products, most of the heating methods currently used are resistance wire heating. Since the heating efficiency of such a heating method is relatively low, there is a problem that the amount of atomization is small and the energy utilization is insufficient. In 2007, the applicant proposed a nano-scale ultra-fine space heating atomization solution (application numbers 200710121524.6 and 200720173030.8, named

The Chinese invention patent application and the utility model patent (the electronic cigarette with the nano-scale superfine space heating atomization function) can significantly improve the heating atomization efficiency, but the production cost thereof is relatively high.

In addition, it is not difficult to find that most of the patents related to the currently published electronic cigarettes use rechargeable batteries to supply power to their atomizers. As a substitute for cigarettes, e-cigarettes first need to be compact, otherwise they are too heavy to carry or use. Rechargeable batteries have the advantage of strong endurance, but they have obvious disadvantages in smoking cessation products. The specific performance is as follows: Firstly, the weight of the rechargeable battery is large, which is not conducive to reducing the overall weight of the electronic cigarette; secondly, the battery life of the rechargeable battery is strong, so that the sustainable smoking time of the electronic cigarette is much longer than that of the traditional cigarette, which will result in It is not easy for smokers to control the amount of smoking, which in turn can not effectively quit.

detailed description

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

Considering that the power supply and the smoke body control unit of the existing electronic cigarette mostly adopt an integrated design scheme, which is easy to cause the circuit to be automatically connected due to vibration during transportation or carrying, the present invention adopts the plugging method to connect the power part and the body part of the cigarette. Separate to prevent the circuit from being automatically turned on during transportation or carrying. In addition, the existing electronic cigarettes are threaded to connect the atomizer to the body of the cigarette. When charging, the atomizer is first unscrewed, and then the cigarette body and the charger are screwed together, which is very troublesome. Ben The introduction of the inventive plugging method will greatly facilitate the charging of the electronic cigarette. It should be particularly pointed out that the plugging method introduced by the invention can be extended to other components of the electronic cigarette, and the electronic cigarette can be made into a multi-segment plugging method according to different needs, which can greatly enhance the flexibility of the electronic cigarette.

As can be seen from Figures 1-3, the power supply portion and the body portion of the electronic cigarette of the present invention are separate structures for easy plugging, convenient for charging, and avoiding the problem of automatic circuit connection caused during transportation or carrying. In this embodiment, the shape and size of the electronic cigarette are similar to those of a conventional cigarette, and the habit of the smoker is not substantially changed.

As shown in FIG. 3, the capacitor-provided heat-heated electronic cigarette provided by the present invention is composed of a power source portion, a body portion and a hollow mouthpiece.

Specifically, the power supply portion (shown in FIG. 1) includes: a power supply 1 powered by a capacitor; an indicator light 2 mounted at the rear end of the power supply 1; a pair of electrode plug connectors 3 mounted on the front end of the power supply 1 and a lead-in connector 4. The body portion of the body includes (as shown in FIG. 2): a hollow tobacco rod 5; a pair of electrode insertion ports 6 and a lead wire insertion port installed at the rear end of the hollow tobacco rod 5; and sequentially mounted in the hollow cavity of the hollow tobacco rod 5 The electrode insertion interface 6 and the control circuit module 8 before the lead insertion interface 7, the heating atomizing device 9, the liquid suction head 10 and the nicotine storage tank 12; the nicotine liquid storage chamber 12 is provided with a sponge body, and the wall of the chamber is provided There is a liquid inlet 11; both ends of the liquid suction head 10 are in contact with the heating atomizing device 9 and the sponge body, respectively.

As shown in FIG. 3, the power supply portion is separated from the body portion of the cigarette or through the electrode plug connector 3, the lead plug connector 4 and the electrode plug connector 6, and the lead plug connector 7 are connected by plugging, and a mechanical bayonet is provided at the joint. The anti-off device of the cigarette body is connected or screwed at the front end of the cigarette body portion and the rear end of the hollow cigarette holder 13; the power source 1, the indicator lamp 2, the control circuit module 8 and the heating atomization device 9 are electrically connected in sequence.

The functional principle of each component is described in detail below:

The power supply part is charged by an external capacitor charger, and the external charger can be an AC/DC conversion charger. Electrical appliances, computer USB interface chargers, DC batteries (or rechargeable batteries) chargers, solar battery chargers or human charging (such as hand-held, hand-operated, etc.). When charging, the power supply is partially from the body of the smoke. Pull out and charge through the electrode plug connector 3. It should be noted that the charging interface of the present invention is not limited to the electrode plug connector 3, and the charging interface can also be disposed at the front end of the power supply portion (near the indicator light 2), or the power supply portion. One of the major features of the electronic cigarette charging method of the present invention is human charging, because the advantage of fast charging speed makes the charging method practical, and this charging method is almost unrealistic for conventional rechargeable batteries.

Power supply 1 is powered by a single super capacitor, or multiple super capacitors in parallel, or multiple super capacitors in series. Supercapacitors are new high-efficiency energy storage devices that are different from traditional capacitors in recent years. They are characterized by light weight, high energy storage density, small size, long life, low internal resistance, large capacitance, especially charge and discharge speed. Far more than conventional batteries. Because it can store a large amount of electric energy for a long time in a small volume, the super capacitor has the power capability for small-sized electric equipment, and also shows the unique advantages that conventional rechargeable batteries do not have, such as the internal resistance is significantly smaller than the rechargeable battery, charging The speed is much larger than that of the rechargeable battery, which is very convenient for the electronic cigarette user to charge or suck at any time according to personal preference. So far, electronic cigarette products basically use rechargeable batteries as the power source, and the charging speed is very slow. It takes several hours to complete one charge, which is very inconvenient for users; and the charging process of super capacitors is very fast, only 2 In minutes or so, real-time performance is very good and can be greatly convenient for users. In addition, conventional rechargeable batteries can cause secondary pollution to the environment, while supercapacitors do not. Therefore, for an extremely large amount of electronic cigarette products, super capacitor is an ideal high-efficiency long-life green power source.

The indicator light 2 can be made by a light-emitting diode (LED), and different illuminating colors can be selected according to requirements. The indicator light is connected to the power supply part, and is controlled to be turned on and off by the control circuit module 8. When smoking, the indicator light 2 is on; when not in use, the indicator light 2 is off.

The electrode plug connector 3 of the power supply portion and the electrode plug connector 6 of the body portion of the cigarette body, and the lead plug connector 4 of the power source portion and the lead plug connector 7 of the body portion of the cigarette are connected by plugging, and a mechanical bayonet type anti-off device is disposed therebetween. The plug-in method has both electrical and mechanical connections. Compared with the existing threaded connection method, the connection method is more convenient and reliable, and has obvious advantages. It has never been used in e-cigarettes or other DC consumer electronic devices. In addition, it should be particularly pointed out that the existing capacitor or super capacitor is generally connected to the electrical device by means of a splicing method. The quick plugging method adopted by the present invention is a new connection method of the capacitor type energy storage device. The connection mode is convenient for quick connection and separation with the electric device, and the e-cigarette product can effectively solve the problem of automatic connection during transportation or carrying, and on the other hand has the advantages of convenient and quick use.

The control circuit module 8 is a control circuit including a differential pressure sensing element. Wherein, the differential pressure sensing element is configured to sense a micro differential pressure switching control circuit generated by the pumping action, and when the differential pressure sensing element senses a pressure difference caused by the pumping action, the control circuit is turned on by the power source 1 2. An electrical circuit composed of the control circuit module 8 and the heating atomizing device 9; otherwise, the electrical circuit is disconnected. In order to enable the power supply unit to provide a stable power output (constant voltage or constant current output), the control circuit of the present invention further includes a step-up conversion circuit or a buck conversion circuit and a boost conversion circuit.

Moreover, no delay circuit is provided in the control circuit of the present invention. Delayed circuits are generally used in existing electronic cigarettes to increase the atomization amount of the liquid smoke. The early adoption of this method is partly due to the low efficiency of the atomization method used, and on the other hand, because the rechargeable battery used has a limited discharge speed. Thus, further enthalpy results in low heat atomization efficiency. Although this approach can to some extent compensate for the shortcomings of the prior art, the atomization time is significantly greater than the pumping time, resulting in a difference from the traditional smoking method. On the one hand, the improvement of the atomization technology can significantly enhance the heating atomization efficiency. On the other hand, the super capacitor power supply mode is adopted, and the discharge speed is also significantly larger than that of the rechargeable battery, thereby ensuring efficient atomization without using a delay circuit. .

The hollow tobacco rod 5 is a hollow thin-walled tube which can be made of a metal material such as stainless steel, copper, aluminum, titanium alloy, magnesium alloy, etc., or can be made of a non-metallic material such as polytetrafluoroethylene or plastic having poor thermal conductivity. It can be made of transparent materials such as glass, plexiglass, transparent ceramics, etc., allowing the user to see the process of smoke generation and experience the fun that ordinary smoking can't feel.

Preferably, the tobacco rod 5 may be made of a low thermal conductive material such as polytetrafluoroethylene (thermal conductivity: 0.2 W/m. C) or the like. The tobacco rods of the existing electronic cigarette products generally adopt stainless steel tubes (thermal conductivity of about 16 W/m. °C) or copper tubes (thermal conductivity of 398 W/m · V). Because the thermal conductivity of polytetrafluoroethylene is much smaller than no Stainless steel and copper, therefore, provide significant thermal insulation against heat transfer from the heated atomizing device to the surface of the tobacco rod. On the one hand, it can effectively alleviate the problem of the smoking of the existing electronic cigarette products, and on the other hand, it can also improve the feel of the electronic cigarette (if stainless steel or copper is used, when the temperature is low, the electronic cigarette will have an icy discomfort. Feeling). Further, PTFE density of about 2200kg / m ^3, stainless steel, a density of about 7800kg / m ^3, the copper density of about 8900kg / m ^3, so as tobacco stems polytetrafluoroethylene material may also effectively reduce the electron The weight of the smoke makes it closer to the lightness of conventional cigarettes. In addition, the use of Teflon material can also increase the transparency of the tobacco rod, visualize the atomization process and increase the user's enjoyment.

The heating atomization device 9 is composed of an atomization chamber and an electric heater; the atomization chamber is a ceramic material atomization chamber; the electric heater is a positive temperature coefficient resistance heater, a porous ceramic resistance heater, a metal fiber or a resistance wire heater; Positive temperature coefficient resistance heater The positive temperature coefficient of the resistance has a Curie temperature of 70 ° C ~ 200 ° C, the resistance value is 0.5 Ω ~ 10 Ω _; the resistance value of the porous ceramic resistance heater is 0.5 Ω ~ 10 Ω _; The heater has a resistance value of 0.5 Ω to 10 Ω. Alternatively, a gap or a heat insulating material may be provided between the hollow tobacco rod 5 and the heating atomizing device 9 to further achieve the effect of heat insulation.

The nicotine storage tank 11 is used for storing a liquid nicotine solution, which is internally provided with a liquid absorbing sponge, and liquid nicotine is supplied to the heating atomizing device 9 through the liquid suction head 10. The nicotine filling port 11 is located on the outer wall of the nicotine storage tank 12. When the hollow mouthpiece 13 is removed, the nicotine filling port 11 needs to be exposed outside the hollow rod 5 to facilitate the addition of the liquid nicotine solution. Nicotine filling port 11 is sealed with a gland to prevent leakage; when adding nicotine, temporarily open the gland. The hollow cigarette holder 13 is installed at the end of the tobacco rod 5 near the nicotine storage tank 12, and is connected or screwed by plugging, which is very convenient to replace. In addition to the above design, the nitric acid storage tank 12 can be filled with a pen-and-bold design, similar to the way in which the steel pen absorbs ink. The sponge in the nicotine storage tank 12 is a sponge of stainless steel fiber, copper fiber, gold fiber, platinum fiber, silver fiber, non-woven fabric, ceramic fiber, glass fiber, activated carbon or porous ceramic. Optionally, the liquid suction head (10;) is a liquid suction head made of foamed nickel.

The hollow mouthpiece 13 is a hollow injection molded hollow mouthpiece or a silicone hollow mouthpiece, and the outer shape of the front end portion is circular, flat or closed. A check valve can be arranged in the mouthpiece 13 so that the airflow can only be single in the mouthpiece To the flow, it can effectively prevent the circuit from being connected due to malfunction (such as airflow caused by blowing, vibration, etc.).

The electronic cigarette of the present invention can also provide an air inlet passage between the cigarette holder 13 and the tobacco rod 5, and can also provide an air inlet passage in the electrode insertion port 6 or the lead super interface 7, or at the same time between the cigarette holder 13 and the tobacco rod 5. An intake passage is provided in the electrode insertion port 6 and in the lead super interface 7, to reduce the suction resistance. When smoking, the airflow enters the hollow rod 5 through the air inlet and is mixed with the atomized nicotine gas to form aerosol smoke. The difference between the arrangement of the intake passages and the arrangement of the existing electronic cigarette intake passages is that the intake passages of the existing electronic cigarettes are generally disposed in the threaded connection gaps, or the intake holes are specifically opened.

The capacitor-powered, heat-sprayed electronic cigarette of the present invention can be similar in shape and size to conventional cigarettes, cigars or pipes, and can be designed in a variety of individual shapes.

The electronic cigarette provided by the invention uses a power supply part of a split design to supply power to the heating atomizing component and the indicator light with the high-efficiency atomization function, and exhibits many outstanding advantages different from the prior art. Due to the use of capacitor power supply, it is lighter in weight than conventional lithium batteries. In particular, a prominent feature of the electronic cigarette is that it is extremely fast charging, and one charge only provides the equivalent amount of smoking for a conventional cigarette, thereby helping the quitters to be effective. Control the amount of food intake. The outer wall of the power supply does not need to be separately provided to ensure the power supply capacity of the electronic cigarette unit is improved.

In addition, the rods are made of lightweight metal and non-metallic materials, which can reduce the weight of electronic cigarettes and are closer to traditional cigarettes. Due to the split design, the prominent feature of the electronic cigarette is that it is convenient to charge, and there is no automatic connection problem during transportation or carrying. Further, the electric heating atomizer is made by using a positive temperature coefficient resistor, a multi-hole ceramic resistor, a metal fiber, a foamed aluminum or a resistance wire. The remarkable feature of the electronic cigarette is that it has a very efficient atomization function. The form of the electronic cigarette is not limited to conventional cigarettes, but may be made into a cigar, a pipe, or other personalized form.

The atomizer of the electronic cigarette of the invention is made of a positive temperature coefficient resistor (PTC), a porous ceramic resistor, a metal fiber, a foamed aluminum or a resistance wire. Due to the use of capacitors, the charging process of the capacitor is generally completed in 1~2 minutes, which can meet the requirements of fast charging, and the capacitor can be charged once. After electricity, its power can reach the atomization amount equivalent to that of a traditional cigarette. It can easily control the smoking amount while satisfying the smoking cessation of smoking cessation. In addition, the capacitor has the advantage of light weight; PTC, porous ceramic resistor, foam The electric heating atomizer is made of aluminum or metal fiber, which can significantly enhance the atomization effect. Up to now, domestic and foreign literatures and patents have not used electronic cigarettes that use capacitors to supply PTC, porous ceramic resistors, metal fibers or resistance wire atomizers. The present invention opens up a PTC, porous ceramic resistor, metal fiber for this type. Or the electronic cigarette of the electric resistance wire atomizer implements a technical solution of fast charging.
