Problems to be solved by the invention

[0003] The vaporizer 50 described above is configured so that the chemical liquid 51 in the container 52 gradually decreases due to the evaporation from the liquid absorbent core 53, so that the container 52 can be replaced. Transparent materials are used so that the replacement time can be visually confirmed.

[0004] However, if the container 52 is made up of a glass cover in consideration of decorativeness and texture, it is difficult to flatten the bottom surface of the container 52. As a result, there was a risk that the chemical liquid 51 that could not be sucked up by the liquid absorbent core 53 remained in the bottom corner of the container 52. In this case, although the chemical solution cannot evaporate, the chemical solution remains visually. As a result, the user cannot accurately grasp the replacement time of the container 52. As a result, the desired deodorizing effect and aroma effect cannot be obtained.

[0005] Such problems are not limited to the case where the material of the container 52 is glass, but even when other material forces such as a transparent resin are used, the evaporator 50 is inclined or the absorbent core When the lower end of 53 is separated from the bottom surface of the container 52, the chemical solution 51 in the container 52 cannot be completely consumed, and the same problem as described above occurs.

The present invention has been made to solve such problems, and an object of the present invention is to provide a vaporizer capable of surely vaporizing a chemical solution in a container.

Means for solving the problem

[0006] The object of the present invention includes a container for storing a chemical solution, and a liquid absorption part that is inserted into the container and partially exposed to the outside of the container, and the chemical solution in the container is exposed to the liquid absorption. A vaporizer configured to vaporize from a part is achieved by a vaporizer comprising an evaporation heating body for heating the container.

[0007] In this evaporator, it is preferable that at least a part of the heating element for evaporation is disposed below the lower end of the exposed portion of the liquid absorption. Specifically, it is preferable that the heating element for evaporation is disposed adjacent to a side wall of the container.

[0008] Alternatively, it is preferable that the heating element for evaporation is arranged so as to heat a lower portion of the container. Here, the arrangement position of the evaporation heating body for “heating the lower part of the container” is preferably a position in the vicinity of the container and below the maximum height of the stored chemical solution. A position where heating is intensive is more preferable. In particular, the heating efficiency of the chemical solution can be maximized by disposing the heating element for evaporation so as to be close to the bottom surface of the container.

[0009] The above-described evaporator may further include a blowing unit that blows air to the exposed portion of the liquid absorption. Further, instead of the air blowing means, or in combination with the air blowing means, a transpiration heater for heating the exposed portion of the liquid absorption can be further provided.

The invention's effect

[0010] According to the present invention, it is possible to provide a vaporizer capable of reliably vaporizing a chemical solution in a container. Brief Description of Drawings

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a side view showing a part of the evaporator according to one embodiment of the present invention. As shown in FIG. 1, the evaporator 1 is configured by mounting a container 4 having a liquid absorbing liquid 2 between a main body 6 and a cover 8.

[0014] Like the conventional liquid absorbent core, the liquid absorbent 2 is a rod-shaped member such as a felt or pulp, and has a lower end in contact with the bottom surface of the container 4 and an upper part exposed to the outside of the container 4. The lid 4a that seals the mouth of the container 4 is held. The shape of the liquid absorption 2 is not particularly limited as long as the chemical liquid can be sucked up, and can be any shape such as a cylindrical shape or a honeycomb shape. Examples of materials for liquid absorption 2 include cotton, rayon, acetate, synthetic resin (polyethylene, polypropylene, polyethylene + polypropylene mixture, polyethylene terephthalate, melamine, etc.), non-woven fabric, asbestos, and inorganic moldings in addition to felt and pulp. In particular, a felt core, an unglazed core, a pulp core, a synthetic resin core or an inorganic molded core is preferable. In addition, the liquid absorption 2 does not necessarily have to be composed of a single member force. It is also possible to configure by combining. For example, the liquid absorption may be constituted by a plurality of liquid absorption wicks, or the liquid absorption may be constituted by a liquid absorption wick and a transpiration mat arranged so that the lower surface is in contact with the upper end of the liquid absorption wick, It may be configured such that the absorbent core absorbs and the raised chemical is spread over the entire mat and evaporated. The container 4 is made of glass in the present embodiment, and stores therein a chemical liquid L such as a fragrance, a deodorant, and a disinfectant. The material of the container 4 is not particularly limited. For example, the container 4 can be made of transparent resin.

The main body 6 includes a holding unit 18 that holds the upper part of the liquid absorption 2 and the container 4 in a predetermined position, and further includes a heating element 10 and a fan 12. The heating element 10 and the fan 12 are energized by turning on the switch 16 with the plug 14 inserted into an external outlet (not shown). The heating element 10 is formed in a block shape, and is provided adjacent to the side wall of the container 4 so that the longitudinal direction is horizontal. The heating element 10 is a positive temperature coefficient thermistor (PTC), ceramic heater, Peltier element, platinum catalyst type heating element, platinum hammer catalyst type heating element, chemical reaction heating type heating element, sheet heater, bottomless vertical type Examples thereof include heaters and two-chromium wire heaters. Further, when the evaporator 1 includes an illumination device, the light source can be used as an incandescent bulb or the like, and the light source can be used as the heating element 10. The fan 12 is disposed so as to be adjacent to the exposed portion 2a of the liquid absorption 2.

The cover portion 8 has a transpiration port 20 formed at a position facing the fan 12, and is fitted to the main body portion 6. Further, a projecting piece 22 that engages with an engaging portion formed on the outer surface of the side wall of the container 4 is provided on the inner surface of the cover portion 8, and a downward force is also inserted between the main body portion 6 and the cover portion 8. The container 4 is detachably supported by engagement with the projecting piece 22.

[0017] According to the evaporator having the above configuration, when the heating element 10 and the fan 12 are energized by the operation of the switch 16, the chemical liquid L sucked up from the lower end of the absorbing liquid 2 is evaporated in the exposed portion 2a, and the fan The air from 12 is discharged to the outside through the transpiration port 20 of the cover 8. With such consumption of the chemical liquid L, the liquid level inside the container 4 gradually decreases. According to the evaporator of the present embodiment, the container 4 is heated by the heating element 10, and thus the inside of the container 4 The remaining chemical solution L is promoted to evaporate. Therefore, even if it is difficult to absorb and raise the chemical liquid L by the liquid absorption 2 due to the chemical liquid L remaining in the bottom corner of the container 4 etc., all the remaining chemical liquid L is evaporated and passed through the liquid absorption 2 Can be evaporated to the outside. As a result, inside the container 4 Since the chemical liquid L can continue to evaporate until the chemical liquid L is completely removed, the transpiration effect of the chemical liquid L can be maximized, and the user can accurately grasp when the container 4 is replaced. When removing the container 4, pull the container 4 downward while holding the main body 6 or the cover 8 to release the engagement with the container 4 using the stagnation of the protruding piece 22. The container 4 can be extracted.

[0018] The heating temperature of the container 4 is appropriately set according to the type of the drug that favors the evaporation of the drug contained in the drug solution L and prevents the unused drug solution L from remaining. However, if the heating temperature is too high, the drug may deteriorate. For this reason, when a chemical | medical agent is a fragrance | flavor, it is preferable to control the temperature of the chemical | medical solution L accommodated in the container 4 at 20-50 degreeC, 25-40 degreeC is more preferable. If it is difficult to maintain the chemical solution L at the above temperature due to the high use environment temperature, a cooling device for cooling the container 4 may be provided.

[0019] The temperature of the chemical liquid L is preferably maintained constant throughout the period of use in order to perform the transpiration of the chemical liquid L at a desired transpiration rate, but actually varies depending on the environmental temperature. . Therefore, a temperature sensor that measures the environmental temperature and the temperature of the surface of the container 4 or the inside of the container 4 is further provided, and the temperature of the chemical liquid L is made substantially constant by controlling the amount of heat generated by the heating element 12 based on the detection result of the temperature sensor. It is preferable to do. As a result, when the environmental temperature is low, the heat generation amount of the heating element 12 can be increased to prevent a decrease in transpiration efficiency, while when the environmental temperature is high, the heat generation amount of the heating element 12 can be reduced. Since it can be reduced to prevent excessive transpiration, the transpiration of the chemical solution L in the container 4 can be stably performed so that the product life is almost as planned.

[0020] While one embodiment of the present invention has been described above, specific embodiments of the present invention are not limited to the above embodiment. For example, in this embodiment, transpiration of the chemical liquid L is promoted by blowing air from the fan 12 to the exposed portion 2a of the liquid absorbing liquid 2, but as a blowing means for blowing air to the exposed portion 2a, A suction fan that generates an air flow from the exposed portion 2a toward the fan 12 may be used. Further, the chemical liquid L may be naturally evaporated from the exposed portion 2a without providing the fan 12.

[0021] In order to promote the evaporation of the chemical liquid L from the exposed portion 2a of the liquid absorbing liquid 2, the above Patent Documents 1 to 3 As described, a transpiration heating element for heating the liquid absorbing liquid 2 may be provided in the vicinity of the exposed portion 2a. This heating element for transpiration can be provided in combination with the fan 12 or in place of the fan 12. As a method for promoting the evaporation of the chemical liquid L from the exposed portion 2a, a method of bringing the vibrator of the ultrasonic vibration generator into contact with the exposed portion 2a can be exemplified.

In the present embodiment, the heating element 10 is provided adjacent to the side wall of the container 4. However, the heating element 10 functions as an evaporation heating body that promotes evaporation of the chemical liquid L inside the container 4. For example, the shape and arrangement are not particularly limited. For example, the shape of the heating element 10 may be formed in a ring shape instead of a block shape as in the present embodiment so that the outer peripheral surface of the container 4 is uniformly heated.

[0023] In order to increase the heating efficiency of the container 4, the heating element 10 is preferably disposed below the lower end of the exposed portion 2a of the liquid absorption 2, but the entire heating element 10 is not necessarily located at the above position. It is sufficient that at least a part of the heating element 10 that does not need to be disposed on the lower side of the exposed portion 2a of the liquid absorption 2 is disposed below. For example, by arranging a rod-shaped heating element so that the upper part is adjacent to the exposed part 2a of the liquid absorption 2 and the lower part is adjacent to the side wall of the container 4, A single heating element can also be used for chemical solution evaporation in

In addition, as shown in FIG. 2, a heating plate 112 having a surface heating element 110 on its surface is configured to be slidably housed in the lower part of the main body 6, and the container 4 is composed of the main body 6, the cover 8, and the like. After being inserted in between, the sheet heating element 110 can be brought into contact with the bottom surface of the container 4 by pulling out the heating plate 112 in the direction of the arrow. Thereby, the planar heating element 110 functions as a heating element for evaporation that heats the lower part of the container 4. In FIG. 2, the same components as those in FIG. 1 are denoted by the same reference numerals.
