[0003] An outline of a heating evaporator is that a heating element such as a heater is provided in a container in which a liquid container is set at a lower portion, and the heating element applies heat to a liquid-absorbing wick that sucks up a chemical solution in the liquid container. Thus, a structure is provided in which vaporization and transpiration are promoted and diffused to the outside through a transpiration port provided above the vessel.

[0004]

Since the liquid medicine in the liquid container is consumed, the liquid container is replaced with a new liquid container when the liquid container becomes empty.

[0005] The liquid container can be replaced by rotating the male screw portion of the liquid container to be screwed with respect to the female screw portion of the body. In order to rotate the liquid container, the shape of the liquid container is determined to be substantially cylindrical from the relationship of the rotation space, etc., and the degree of freedom of design is limited by the relationship of being restricted by the shape of the cylindrical liquid container even in the overall shape. Is not present, and
A female thread must be machined on the body side, which is undesirable in terms of workability.

In addition, since the liquid container is supported by the screw, if the screw is stopped halfway during the screw fitting, the correct setting position of the liquid absorbing core with respect to the heating element may be shifted in the vertical direction. There was a problem such as.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a heating and evaporating apparatus which can obtain a large degree of freedom in design including a liquid container and can surely ensure a correct setting position of a liquid absorbing core. And

[0010] Further, since the liquid container can be exchanged by insertion / removal, the shape of the liquid container is not limited to a cylindrical shape, and the degree of freedom in design is increased.

In addition, since the engagement completed state can be reliably determined by the engagement projection and the engagement recess, a correct setting position of the liquid-absorbing wick can be reliably ensured.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be specifically described below with reference to FIGS.

FIG. 1 shows a front view of the heating evaporator 1.

The evaporator main body 3 of the heating evaporator 1 is made of a synthetic resin material. A heating section 5 is disposed inside the evaporator main body 3, and a liquid container 7 containing a chemical liquid is detachably mounted on a lower portion thereof. Insertion is set. The evaporator main body 3 can be divided into front and rear portions 3a and 3b from the butt line 11 shown in FIG. 4 by loosening the fastening screw 9. A slit-shaped air inlet 15 is provided on each of the left and right sides as viewed from the front.

As a result, the air taken in from the air inlet 15 ensures a reliable upward flow toward the upper evaporation port 13.

The transpiration port 13 is formed by a main opening 17 which is formed in a round hole and penetrates up and down, and a sub-opening 19 having an opening area smaller than the main opening 17 at four peripheral edges of the main opening 17. The opening area can be adjusted by the opening / closing control means 21.

The opening control means 21 includes a manual operation lever 23 projecting outward from the evaporator main body 3 and an operation lever 23.
And a strip-shaped control door 25 that expands and contracts the opening area of the transpiration port 13 by sliding movement of the transpiration port 13 (arrow in FIG. 3).

As shown in FIG. 4, the operation lever 23 can be slid upward and downward about the standard position P1. When the operation lever 23 is operated upward, the opening area of the transpiration port 13 is gradually reduced. The opening area is set to be the smallest at the upper level.

By operating downward from the standard position P1,
The opening area of the transpiration port 13 is set to increase gradually, and the opening area is maximized at the lowest order.

On the other hand, the liquid container 7 has a liquid absorbing core 35 extending upward from the inside of the container main body 7a via the cap attaching portion 7b.
And a convex engaging projection 37 formed in an elliptical shape as shown in FIG. 2 on the front surface of the container body 7a.

When the container main body 7a is inserted into the lower part of the evaporator main body 3, the engaging convex part 37 forcibly pushes and expands the skirt of the evaporator main body 3, thereby forming an elliptical through hole. The liquid container 7 is capable of engaging with the engaging concave portion 39, and has a play α in which the liquid container 7 descends by one step under its own weight when the engagement is completed.

The play α is ensured by making the diameter d of the engaging projection 39 slightly smaller than the diameter D of the engaging recess 39.

The engaging recess 39 does not necessarily have to have the shape of a through hole, but may have an elliptical depression. In this case, it is also possible to provide a means for providing the engaging concave portion 39 in the liquid container 7 and the engaging convex portion 37 in the evaporator main body 3, respectively.

The liquid absorbing core 35 is made of a material which is strong against heat for sucking up the chemical solution in the container body 7. When the liquid container 7 is inserted and set in the lower part of the evaporator body 3, the heating element 45 of the heating section 5 is set.
It is set to a length that protrudes slightly upward from.

The heating section 5 is surrounded by an insulating material as shown in FIG. 6, and comprises a heating control section 43 and a heating element 45.
And is fixedly supported by a support member 51 provided therein. The terminal 43 a of the heating control unit 43 is attached to the support member 51 and is electrically connected to a plug 31 protruding from the rear side of the evaporator main body 3. This is a PTC heater that flows and applies heat to the heating element 45.

The heating element 45 is formed in a ring shape that surrounds the outer periphery of the liquid absorption core 35 with a slight gap.

In FIG. 1, reference numeral 53 denotes a pilot lamp which is turned on during use.

According to the heat evaporator 1 configured as described above, by inserting the plug 31 into the socket 33, heat is given to the liquid absorbent core 35, and the vaporized chemical solution is diffused outside from the evaporation port 13. You. At this time, in order to replace the liquid container 7 with the new liquid container 7, the plug 31 is removed from the outlet 33, and the empty liquid container 7 is put on the empty liquid container 7 by hand. By pulling downward so that the engagement is released, the evaporator body 3 can be detached. At this time, the liquid container 7 is lowered by one step, so that the liquid container 7 is easy to handle and is easily pushed up once by the play α, and then easily pulled out.

Next, in order to insert and set a new liquid container 7, as shown in FIG. 2, the liquid container 7 is inserted into the lower part of the evaporator body 3 with the liquid absorbing core 35 of the liquid container 7 at the head. At this insertion,
The engaging protrusion 37 engages with the engaging recess 39. When the engagement is completed, the user releases the hand from the liquid container 7 to be fixedly supported in a state of being lowered by one step due to the play α between the engaging convex portion 37 and the engaging concave portion 39.

At this time, the liquid absorbing core 35 is set at the correct position with respect to the heating element 45 of the heating unit 5 by the completion of the engagement between the engaging convex portion 37 and the engaging concave portion 39, and the liquid container 7 is rotated. Since it can be attached and detached without being attached, it is not necessary to be confined to the cylindrical shape, and the degree of freedom in design is increased.

[0031]

As described above, according to the heat evaporator of the present invention, the liquid container can be easily replaced by the play of the engaging convex portion and the engaging concave portion, and the cylindrical shape can be prevented. This increases the degree of freedom in design.

Further, since the engagement completed state can be ascertained by the engagement projections and the engagement recesses, the correct setting position of the liquid absorbent core can be ensured.
