It consists of a top lid with one slit on the side and a bottom part, and the bottle is placed in the bottom part.

[The problem that the idea aims to solve]

In the first disclosed technology, the amount of the medicinal solution in the bottle must be checked with the main body sideways or upside down, and in this case, it is not possible to know the liquid level in the bottle when it is in an upright position. The exact amount remaining was unknown.

Furthermore, the temperature of the liquid in the bottle rises due to the temperature of the heating element during heating, promoting thermal deterioration of the chemical solution and causing liquid leakage due to an increase in internal pressure.

Furthermore, in the second and third disclosed techniques, the inside of the bottle can only be seen from a limited number of directions (left, right, top and bottom) relative to the main body of the device, and even if it can be seen, the inside is dark and the liquid level cannot be seen. It was difficult to visually recognize it.

For this reason, in the case of the second disclosed technique, the liquid level cannot be checked unless the main body of the device is turned sideways or upside down, and in the case of the third disclosed technique, it is necessary to remove the bottom part from the main body to check the liquid level. Ta.

Further, in any of the first to third disclosed techniques, it was not possible to check the liquid amount in a dark place, such as when using the device in a liquid.

[Purpose of invention]

The present invention was developed in view of the above circumstances, and its purpose is to expose a part of the body of the bottle and expose it to the outside air to promote cooling in order to reduce the thermal influence of the heating element. The objective is to prevent liquid leakage due to an increase in internal pressure during heating, improve thermal stability, make it easier for outside light to enter the inside of the bottle, and make it easier to visually check the remaining amount of chemical liquid. In addition, by illuminating the liquid surface of the bottle with the illumination means, it is easier to visually check the remaining amount of the drug solution in a dark place, and it is possible to see it reliably even in a dark place. Sometimes, this can be seen as a pilot and illumination from the top of the device body, and furthermore, even if the lighting means is located at a distance from the top of the device body, this illumination means can be used for energization detection. An object of the present invention is to provide a heating evaporation device that can perform the following steps.

[Means and actions for solving problems]

In order to achieve the above object, the present invention accommodates a bottle having a liquid absorbent wick that absorbs the medicinal liquid contained inside the device body, and heats the liquid absorbent wick inside the device body to transpire the medicinal liquid. In the heating evaporation device, the device main body is provided with a bottle exposing device that exposes a part of the body of the bottle in the circumferential direction over substantially the entire length in the height direction. An illumination means for illuminating the liquid surface is provided, and a light guiding member made of a transparent material and formed in the shape of a rod is provided inside the apparatus main body, with one end facing the illumination means and the other end visible from the top of the apparatus main body. The configuration is set up as follows.

By exposing a part of the body of the bottle, this body is brought into direct contact with the outside air, promoting cooling to reduce the heat effect caused by the heating element during heating, and reducing the increase in internal pressure during heating. This prevents liquid leakage, improves the thermal stability of the chemical liquid, and makes it possible to darkly detect changes in the chemical liquid level inside the bottle by using lighting means and by making the entire height of a part of the bottle body visible. It can be clearly seen from start to finish even in places, and when it is being illuminated by the illumination means, this can be seen as a pilot and illumination from the top of the device body.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings. FIG. 1 shows a longitudinal section of a heating evaporation device according to an embodiment of the present invention. In the figure, reference numeral 1 denotes a main body of the apparatus, in which a bottle accommodating section 2 is formed, and an opening 3 is provided in the front part of the bottle accommodating section 2 and the peripheral wall section 4. And this opening 3
is a part of the body of the bottle 16 to be accommodated in the bottle accommodating portion 2, and is large enough to expose approximately the entire length in the height direction. Also, the peripheral wall portion 4
A window 5 is formed on the rear surface of the vehicle. An opening 7 is formed in the upper surface 6 of the bottle accommodating portion 2 . A heating element support part 8 is provided on the upper surface part 6 so as to be located on the upper peripheral edge side of the opening 7, and a heating element 9 is attached to this heating element support part 8. This heating element 9 is provided with a liquid absorbent wick insertion hole 10.

An illumination light 11 is provided inside the device main body 1 at a position behind the window 5. Further, the upper surface part 12 of the apparatus main body 1 is provided with a ventilation hole 13 located above the heating element 9, and the upper surface part 12 is provided with a mounting hole 14, which is filled with a transparent resin. A rod-shaped light guide member 15 made of the following is attached, and the lower end of the light guide member 15 is formed into a slope 15a, and this slope 15a faces the illumination lamp 11.

A bottle 16 is accommodated in the bottle accommodating portion 2. This bottle 16 contains a transpirable chemical solution 17 such as an insecticide, repellent, deodorant, bactericide, fragrance, etc., and a liquid absorbing wick 18 is attached to the mouth 16a of the bottle 16. The lower part of the liquid absorbent wick 18 is immersed in the chemical liquid 17, and the upper part of the liquid absorbent wick 18 is inserted into the liquid absorbent wick insertion hole 10 of the heating element 9.

Then, electricity is applied to the heating element 9 and the illumination lamp 11 to cause the heating element 9 to generate heat and to turn on the illumination lamp 11. The chemical liquid 17 absorbed by the liquid-absorbing wick 18 is evaporated by the heat generated by the heating element 9 and discharged to the outside through the ventilation hole 13.

In this case, a part of the body 16b of the bottle 16 is exposed over almost the entire length in the height direction at the opening 3 and is in direct contact with the outside air.
Cooling is promoted to reduce the thermal effects of the heating element 9 during heating use, and the level of the internal chemical liquid can be clearly seen from beginning to end. Therefore, liquid leakage due to an increase in internal pressure during heating is prevented, the thermal stability of the chemical liquid 17 can be improved, and the level of the chemical liquid can be monitored satisfactorily.

Furthermore, since light from the outside directly hits the body 16b of the bottle 16, the amount of liquid (liquid level) inside can be visually confirmed.

When the lighting lamp 11 is turned on, the bottle 16 is illuminated through the window 5. For this reason, the amount of liquid (liquid surface) is clearly illuminated due to the difference in the refractive index of light between the chemical liquid 17 and the air layer.

Further, the light from the illumination lamp 11 is irradiated to the outside through the light guide member 15 and becomes illumination, so that it can be seen that the device is energized from the outside.

At this time, since the light guide member 15 is rod-shaped, the light is guided over a long distance by the light guide member 15.

FIGS. 2 and 3 show other examples of illumination positions.

Further, the material of the bottle may contain an ultraviolet absorber to block ultraviolet rays contained in large amounts in sunlight and lamps, thereby increasing the stability of the drug over time. Further, ventilation holes and gaps may be provided in the main body of the device to further improve the evaporation of the chemical solution and the cooling effect.
