The present invention relates to a heating evaporation device that evaporates by heating a core with a heating element.

[Conventional technology]

The heating evaporation device shown in Japanese Utility Model No. 60-125876 is known.

That is, a container is formed by the substantially cylindrical peripheral wall, the upper wall, and the lower wall, the bottle mounting recess is formed on the lower wall, the heating element is mounted on the upper portion of the peripheral wall, and the volatilization hole is formed on the upper wall. Formed, set the bottle in the bottle mounting recessed portion, the liquid absorbent core is exposed to the inside of the heating element, and the liquid absorbent in the bottle is evaporated by heating the liquid absorbent core by the heating element,
The vaporized chemical solution is volatilized from the volatilization hole by an air flow generated between the slit-shaped ventilation hole formed on the peripheral wall and the volatilization hole.

Further, as shown in Japanese Utility Model Laid-Open No. 63-165182 and Japanese Utility Model Laid-Open No. 63-187868, the inside of the container is divided into a bottle storage chamber and a heating chamber, and the liquid absorption core of the bottle provided in the bottle storage chamber is A heating evaporation device is known in which heating is performed by a heating element provided in a heating chamber and air is taken in through a ventilation hole formed in a lower portion of the bottle storage chamber.

[Problems to be solved by the device]

In the former heating evaporation device, the heating element is attached to the upper part of the peripheral wall via the stopper, the inside of the container is separated into the upper chamber and the lower chamber by the heating element and the stopper, and the upper chamber has a volatilization hole. Is formed, and a vent hole is formed in the side wall of the lower chamber, and the lower chamber and the upper chamber communicate with each other only through the gap between the hole of the heating element and the liquid absorption core, so that the air flowing in from the vent hole is in the upper chamber. Since it is difficult to flow into the container and the temperature inside the container tends to rise, it is necessary to enlarge the ventilation hole to take in a large amount of air, which not only impairs the strength and aesthetics of the container due to the large ventilation hole, but also Since air flows into the container, it is easily affected by the outside air.For example, in the case of cross wind, the heating element is cooled rapidly and the drug heating temperature drops, preventing drug evaporation, and stable drug evaporation is maintained depending on the state of the outside air. It is not possible, and moreover, it is difficult for air to flow into the upper chamber, so Since there is almost no ventilation in the side part and the drug evaporated from the absorbent core stays inside without volatilizing smoothly from the volatilization hole, a condensation phenomenon of the evaporated drug easily occurs, and the evaporated drug adhering to the upper chamber is removed. Maintenance is very troublesome because it needs to be cleaned.

Also, since the heat of the heating element is directly transferred to the bottle, the bottle may be heated and the air layer and liquid layer in the bottle may thermally expand to leak the drug solution, and the liquid drug in the bottle may deteriorate due to the heat. There is.

Further, in the latter heating evaporation device, since air enters the gap between the peripheral wall of the bottle storage chamber and the bottle from the ventilation hole, in order to smoothly take in the air between the peripheral wall of the bottle storage chamber and the bottle. It is necessary to make the gap large, resulting in a container that is much larger than the outer diameter of the bottle, which raises costs and limits aesthetics.

Therefore, an object of the present invention is to provide a heating evaporation device capable of solving the above-mentioned problems.

[Effect of device]

The projecting portion 1a provided on one side of the outer periphery of the lower portion of the container 1 forms an air introduction space 38 that is opened to the side, and the air introduction space 38 is opened to the upper part of the bottle storage chamber 13 through the communication hole 27, and the air introduction is performed. A vertically long rectifying body is provided on the inner surface of the space 38 toward the communication hole 27. Outside air flows from the air introduction space 38 into the upper part of the bottle storage chamber 13 through the communication hole 27, and turbulent outside air is generated. When it flows through the introduction space 38, it is converted into a laminar flow in a certain direction, and is guided by the flow straightening plate and smoothly flows into the upper part of the bottle storage chamber 13 in a certain direction from the ventilation hole 27.

As a result, the outside air that has flowed into the upper portion of the bottle storage chamber 13 spirals in the bottle storage chamber 13, gradually passes through the bottle insertion opening 15 and the communication hole 19, and then flows into the heating chamber 12. For this reason, the air introduction space 38 and the bottle storage chamber 13 serve as a buffer chamber, and the wind speed and wind pressure entering the heating chamber 12 are weakened so that the heating element 24 is less likely to be affected by the outside air and the medicine heating temperature is always substantially constant. Therefore, stable drug evaporation can be achieved.

Further, since the projecting portion 1a is provided on one side of the lower outer periphery of the container 1 and the power supply chamber 35 for mounting the power supply introducing member such as the conductive blade and the cord is formed together with the air introducing space 38, one projecting portion 1a serves as a power supply introducing member. Since the mounting portion can also serve as the outside air introducing space 38 and the projecting portion 1a is provided on one side of the outer periphery of the lower portion of the container 1, the entire container 1 can be made compact without being too large.

Further, since the outside air is introduced from the air introducing space 38 to the upper part of the bottle storage chamber 13 through the ventilation hole 27, the bottle storage chamber 1
No ventilation holes are required in the lower part of 3, and the effect of the saucer is exerted against natural liquid leakage due to rise in internal pressure of bottle due to atmospheric fluctuation and temperature change, which is a drawback of wicking type chemical solution, and chemical solution leakage As a result, there is no contamination of the floor.

Further, the bottle storage chamber 13 is partitioned from the heating chamber 12 by the partition wall 10, and it becomes difficult for the heat in the heating chamber 12 to be transferred to the bottle storage chamber 13. Furthermore, due to the spiral flow generated in the upper portion of the bottle, it becomes difficult to transfer the heat and the bottle heats up. The heating by the body is remarkably reduced, the air layer and the liquid layer in the bottle are not thermally expanded and the chemical liquid does not leak, and the chemical liquid is not deteriorated by heat.

Air is introduced into the heating chamber 12 through the air introduction space 38 and the vent hole 2.
8, the liquid smoothly flows in through the communication hole 19 and a space is formed around the heating element 24.
The chemical evaporated from 0 is not volatilized smoothly from the volatilization hole 14 to the outside of the container 1 by the heat rising airflow due to the heat of the heating element itself and the air flow, and remains in the heating chamber 12,
The drug coagulation phenomenon does not occur, and even if it slightly occurs, it is quickly volatilized and discharged to the outside of the container 1 by the rising air flow. Therefore, since the drug does not adhere to the container 1, it is necessary to clean the inside of the container. No complicated maintenance is required, and the installation surface is not polluted by dripping.

In terms of appearance, the heating temperature of the medicine can be made substantially constant without providing a ventilation hole on the outer periphery only with the volatilization hole 14 on the upper part,
Outside air is introduced into the upper part of the bottle storage chamber 13, the gap between the bottle storage chamber 13 and the bottle can be significantly reduced, and the overall size is reduced, the weight is reduced, the strength is improved, the aesthetic appearance is not deteriorated, and the light resistance is also high. It is possible to improve the stability of the drug.
