9 Claims. 1

This invention relates to Vaporizers of the type and kind employing an electric heating element for heating water or other fluid to generate vapor for discharge of a medicated or other vapor from the device. More particularly, the invention deals with a device of the character described, which is so designed as to provide substantially instantaneous generation of vapor for quick and continued supply of the medicated or other vapors, thereby producing an efficient and economical type of device of the kind under consideration.

The novel features of the invention will be best understood from the following description, when taken together with the accompanying drawing, in which certain embodiments of the invention are disclosed and, in which, the separate parts are designated by suitable reference characters in each of the views and, in which the drawin is a sectional view through a device made according to our invention with part of the construction broken away.

In illustrating one adaptation and use of our invention, we have shown the same applied to a jug or vessel having an insulated wall such as the commonly known Thermos jugs for the purpose of holding a fluid temperature and, thus, minimizing the electric consumption in a prolonged operation of the device. In many instances, vaporizers of the kind under consideration are used for'medicinal purposes for a continued or lengthy discharge of a medicated vapor to ease congested conditions, such as asthma, head colds, hay fever, sinus trouble and the like. On the other hand, the apparatus may be also utilized for the discharge of various insecticides for the treatment of clothing in a closet or, on the other hand, to generally treat or condition a room or compartment for any purpose whatever.

In the drawing, IO represents the jug or container of a large Thermos device, the walls of which are constructed from inner and outer wall portions H and I2 with suitable insulatin material l3 therebetween. The upper end of the jug or container has a large upwardly extending neck I 4 integral with the wall structure thereof and treated, as seen at l5, to receive a detachable cap l6, which forms the mounting part of my improved vaporizing attachment. Inother words, a vessel can be constructed solely for the intended Purpose or a conventional standard Thermos jug can be converted by substitution of the adaptor cap NS for the present closure-cap in using the same as a vaporizing device. Secured centrally to the upper surface of the cap is a 2 plate l1, having a housing portion l8, in which is a socket l 9. In the socket I9 is disposed two electric terminals, one of which is shown at 20, for placing the electric heating element 2| in circuit with an electric source of supply. Adjacent the casing I8 is a small steam or vapor chamber 22 having a tube 23 secured in the lower wall thereof and extending through the plate I! and through the cap 15, as well as an insulating plug 24 disposed upon the inner surface of the cap IS. The plug 24 has two bores 25 and 26; the pipe or tube 23 extends into one bore and the electric wires, one of which is shown at 21, extends from the terminal pins 20 through the bore 26 and contacting with the heating element 2 I.

Arranged in the bore 25 isa governor or control thimble or sleeve 28, having a steam inlet, as at 29, and a condensation discharge, as at 30, the latter'being disposed at the lower end of said thimble, If desired, two of the inlets 28 may be employed, but only one will appear in the sectional view shown.

Arranged upon the plug 24 is a long tube or cylinder 3|, which forms a steam generating cylinder and extends well into the jug or container ID to such a degree as to be exposed to a relatively large part of water or other fluid disposed in said jug or container.

At the lower end of the cylinder 3| is a plug 32 of insulating material forming a support for the lower end of the heating element 2|, as seen at 33, the plug also having a port 34 for admission of fluid into the cylinder 3| to a level common to the level of fluid as contained in the jug or container 10, which level of fluid is indicated Detachable with respect to the top of the chamber 22 is a cap 36 having attached to the" inner surface thereof a chain 31, from which is suse pended a perforated medication or other container 38. Secured to and extending outwardly from the chamber 22 is a discharge spout or nozzle 39.

In the use of the device, the jug or container I0 is partially filled with water or other fluid, after which the vaporizer attachment, as a complete unit, is attached to the jug in the manner shown. The container 38 is filled with the suitable crystal or other medications, or other type of materiahto be used in conjunction with the device and, after which, the socket of an extension cord, from a source of supply, is connected with the plug pins 20 to heat the element 2!. The element may be of any type or kind, but a carbon heating element is preferred. In a matter of from ten to fifteen ing objectionable odors and similar purposes.

seconds the water or fluid within the cylinder 3i becomes heated sufficiently to generate steam or vapor, which rises in the cylinder and is passed through the port or ports 29 and, thus, up into the chamber 22 around the container where it picks up the medication and the vapor is then discharged through the nozzle 39. Any conden sation that may collect will drain back into the cylinder 3| through the port 38. With a relatively large body of fluid, we have found that a device of this type and kind can operate for many hours at a nominal electric consumption and without any danger of overheating and with the continued ejection of vapor from the nozzle for any purpose for which the device i used. The

discharge of medicine has proved to be very desirable from the standpoint oflgiving'con'ifort to those suffering from the ailments of the general type and kind mentioned heretofore. 0n the other hand, various insecticides and other types of chemicals can be utilized for vapor discharge from the device for the treatment of moths other house pests or insects; Whereas the device may be used for purification and/or otherwise treating a room or compartment for counteract- In referring to fluid, it will be understood that the fluid itself may comprise a pie-prepared solution having properties which are suitable for the in tended purpose. of the container 38* or a chemical of some type or kind therein may be optional.

In Vaporizers of the kind under consideration, one of the objectionable features has been the long time required for generation of vapors. This has been quite a nuisance or annoyance to the user. One of the distinctive features of our invention resides in the fact that a substantially instantaneous generation of vapor is provided and this is largely due to the relatively restricted cylinder and the use of a heating element which can be active immediately upon the small body of fluid within the cylinder, without, in any way, materially changing the temperature of the remainder of the fluid in the container or vessel.

We have found from experiene that, while the fluid in the cylinder 3| is sufficiently hot to generate the steam vapors, the fluid in the container or jug would be hardly warm to the touch, at least after a short use of the device. In time, the fluid in. the jug will be heated'to a greater extent but this heating really adds to the effi ciency of operation of the device.
