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.

[0005]

In order to achieve the above object, the structure of the heating vaporizer of the present invention is such that a liquid absorption core provided so as to project from a container filled with a chemical liquid is provided around the liquid absorption core. A heating vaporizer that heats by a heating element and evaporates the chemical liquid sucked up by the liquid absorbing core, and a heating element holding portion that holds the heating element in a state where the liquid absorbing core is separated,
A mounting portion for elastically deforming when the container is loaded to hold the container from a plurality of directions is provided, and a guide portion that engages with the heating element holding portion is formed inside the main body. The guide portion supports the heating element holding portion so as to be movable in the axial direction of the liquid absorbent core.

Further, the container is formed with bulging portions on both sides thereof, and the mounting portion is formed with a hole for fitting with the bulging portion formed on the container on one side thereof and on the other side thereof. A pedestal for receiving the bulging portion is formed.

In the heating vaporizer, it is preferable that a chamfered portion is formed on either one of the portion contacting the mounting portion of the container and the mounting portion.

[0008] Further, the heat generating element is moved up and down in the axial direction of the liquid absorbent core by a rotating operation, and the rotary portion is provided with a scale indicating the position of the liquid absorbent core and the heat generating element on its surface. Is provided.

In the heating evaporator 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 has a structure that is clamped by the mounting portion,
It is easy to position the container securely in the center position. Furthermore, since the liquid absorbent core is held by the heating element holding portion in a state where it does not contact the heating element, and the heating element holding portion is supported by the guide portion so as to move in the axial direction of the liquid absorbing core, heat is generated. It is possible to prevent contact between the body and the liquid absorbent core.
The heating vaporizer having the above structure can be loaded into the main body of the container even when the screw is not provided on the neck of the container. Then, there was a problem in the conventional heating vaporizer,
A spiral groove is provided on the neck of the container and a heating element is brought into contact with the liquid absorption core when the main body having a groove provided to engage with this groove is attached to the container, and at this time, contact is made with the liquid absorption core. It is possible to avoid deterioration of the liquid absorbent core due to decomposition of the drug, which is held in the liquid absorbent due to overheating, due to high temperature. On the other hand, in the same manner as in the conventional heating vaporizer, the heat of the chemical liquid absorbed and retained in the liquid absorption core due to the too large distance between the liquid absorption core and the heating element makes it difficult to evaporate. Can be avoided. Further, if the chamfered portion is formed on either one of the portion that comes into contact with the mounting portion and the mounting portion, the mounting between the container and the main body becomes even easier.
