BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating vaporizer capable of holding a cored container filled with a chemical solution with a sandwiching type mounting portion.

[0002]

2. Description of the Related Art In a heating vaporizer, a part of an absorbent core is inserted into a liquid container, and the absorbent core is heated by a heating element near the absorbent core outside the liquid container to vaporize the liquid in the liquid container. There is something to evaporate. In this type of heating evaporator, some containers are attached to the main body by screwing a screw screwed on the neck of the container with a screw screwed on the main body of the evaporator. Further, a device in which the amount of transpiration is adjustable is disclosed in Japanese Utility Model Laid-Open No. 62-45986. In the one disclosed herein, a configuration in which the position of the liquid absorption core with respect to the heating element is changed by sandwiching the adjustment ring in the threaded portion of the liquid container, and the liquid container and the outer container have a screwed structure, By changing the position of the liquid absorption core by adjusting the rotation of
The bottom of the liquid container is provided with replaceable holding bases of different heights to change the position of the liquid absorption core. Furthermore, the liquid container is placed on the holding base and attached to the side wall of the outer container on which the heating element is fixed. There has been proposed a configuration in which a cam groove is formed and a holder on which a liquid container is placed is engaged with the cam groove stepwise to change the position of the liquid absorption core.

[0003]

However, in the heating vaporizer of the type in which the container and the main body are screwed together, the screwing operation is troublesome, and the core and the heating element may come into contact with each other during use due to improper screwing. It may happen. On the other hand, in the structure using the adjustment ring and the holding table to adjust the transpiration amount, the user has to attach and detach these members, and the management thereof is complicated and the usability is poor. If these separate parts are used, there is a problem that the number of parts increases and the cost increases. Also,
The configuration in which the liquid container and the outer container are adjusted by screwing has a problem that the attaching and detaching operation of the liquid container becomes complicated. Further, in the structure in which the holding table on which the liquid container is placed is engaged with the cam groove to adjust the movement, it is difficult to obtain the engagement accuracy of the cam portion, and there is a possibility that the heat generating element and the liquid absorbing core are misaligned. There was also

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a heating vaporizer capable of improving the detachability of a container and avoiding the contact between the heating element and the liquid absorbent core. To aim.

is there. Further, the container has bulging portions formed on both sides thereof.
The mounting portion is formed on the container on one side thereof.
A hole to be fitted with the bulging part is formed, and the bulging part is formed on the other side.
A pedestal for receiving is formed.

Further, the heating unit is moved up and down in the axial direction of the liquid absorbent core by a rotating operation, and the rotary unit is provided with a scale indicating the position of the liquid absorbent core and the heat generating unit on the surface thereof. Is provided.

In the heating vaporizer having the above structure, the mounting portion of the main body is elastically deformed when the container is loaded, so that the container can be loaded by press fitting, and the container can be easily removed. The workability of attaching and detaching is improved. In addition, since the container is sandwiched, the container can be reliably held at the center position, and therefore the liquid absorbent core is arranged at the central axis position of the heat generating element, so that the heat generating element and the liquid absorbent core are Inadvertent contact with is avoided. Further, in the heating vaporizer having the above structure, the container can be loaded into the main body even when the screw is not provided on the neck of the container.

As shown in FIG. 3, the container 3 has a hemispherical convex surface 3 at a relative position on the flat surface of a flat-shaped tail-shaped container.
a and 3b are provided, and a neck 7 having a truncated cone shape is fastened to the injection port provided at the upper part. At the center of the neck portion 7, a tubular liquid suction lead outlet 7a is integrally provided. The liquid absorbent core 9 inserted into the liquid absorbent core outlet 7a is preferably made of a material that does not deform or expand depending on the evaporative agent used, and has heat resistance of about 150 ° C., for example, felt core or asbestos core. Many components are used initially. In addition, as the medicines, medicinal liquids such as insecticides, acaricides, repellents, aromatics and deodorants are stored.

When the above-mentioned container 3 is press-fitted from below the main body 2, one convex surface 3a of the container 3 is a concave surface 5a in the pedestal 5 of the mounting portion 4, and the other convex surface 3b is a circular hole 6 in the mounting portion 4. They are fitted and fixed. In this state, the neck portion 7 of the container 3 is brought into close contact with the close contact member 8 in the mounting portion 4, and the tip of the liquid absorbent core 9 is at a predetermined position (when the scale of the rotating portion 12 is set to 1, Bottom position). In this state, the socket 23 is inserted into an indoor outlet, and the rotating portion 12
When is rotated, the heating element 17 descends to gradually cover the liquid absorbent core 9 from above and heat the liquid absorbent core 9, so that evaporation of the chemical liquid is activated. Incidentally, the scale is set so that the exposed portion of the liquid absorbent core 9 is completely covered with the scale 5 being max.
When the container 3 becomes a void, it can be easily removed by pulling it out from the side surface.

In the example described above, the case where the convex portions that bulge on both sides of the container are formed and the convex portions are engaged with the mounting portion of the main body has been described, but as shown in FIG. Container 5
It is also possible to form recesses (dotted lines in the figure) on both sides of 3 and form protrusions 55 that engage with these recesses in the main body mounting portion so that the container 53 and the main body 2 engage with each other. further,
You may make it the structure of an attachment part hold a container from 3 directions. 6A and 6B show a cross-sectional view and a bottom view, respectively. As shown in FIG. 6, the tip of each member 66 that holds the container 63 may be bent inward, and the bottom of the container 63 may be supported by these bent portions 67. In the structure shown in FIG. 6, since the container does not need to be formed with any uneven portion, a container having a normal shape can be used.
