Description

[Detailed description of the invention] [Industrial application field]

TECHNICAL FIELD The present invention relates to a heating evaporation device that heats and evaporates chemical liquids such as fragrances and insecticides.

[Background of the invention]

As a heating evaporation device for heating and evaporating chemical liquids such as fragrances and insecticides, a bottle is placed on the bottom lid, and a cylindrical body with a lid and bottom is used, as described in, for example, Japanese Utility Model Application Publication No. 58-45670. The bottom cover is fitted from the bottom side, or as described in Japanese Utility Model Publication No. 44-8361, the bottle is inserted from the bottomless side of the cylindrical body with a lid and bottom, and the mouth of the bottle is screwed. There is something that can be attached to the main body. However, in the heating evaporation device described in Japanese Utility Model Application Publication No. 58-45670, the liquid absorbent wick cannot be accurately fixed to the heating element. However, there are problems such as poor evaporation of the chemical solution. In addition, in the heating evaporation device described in Japanese Utility Model Publication No. 44-8361, when the upper part of the core enters the interior, the insertion part becomes difficult to see, and the upper part of the core often hits the inner wall, making it easy to break.
There are problems in that good transpiration cannot be obtained and furthermore, it is difficult to attach the bottle. Therefore, in order to solve these problems, a heating evaporation device that evaporates the absorbed chemical liquid by heating a liquid absorbing wick partially immersed in the chemical liquid of the bottle is used.
The main body of the device is provided with a bottle insertion part through which the bottle can be taken in and taken out from a substantially horizontal direction, a heating element is provided on the upper side of the bottle insertion part, and a sub-circuit through which the liquid absorbent core of the bottle can be taken in and out from the approximately horizontal direction. A device comprising a U-shaped liquid absorbent wick insertion part has been proposed (Japanese Utility Model Publication No. 63-84240), and in this device, the bottle equipped with the liquid absorbent wick can be inserted into and taken out of the device main body in a substantially horizontal direction. In addition, when setting the bottle, the liquid absorbent wick does not interfere with the heating element or the main body of the device, which prevents damage to the liquid absorbent wick, and furthermore, prevents the bottle from generating heat. It is said that it can be kept in a good position against the body. Although this product is excellent in its own way, it has a U-shaped liquid absorption wick insertion part in the child circuit that allows the liquid absorption wick of the bottle to be inserted and removed from the horizontal direction in the heating element. It has been found that there are problems in that the temperature is relatively low at the tip of the U-shape (the opening of the U-shape), making it difficult for the liquid-absorbing core to be heated evenly from the surroundings, making it difficult to obtain good transpiration. It's here.

[Disclosure of the invention]

A first object of the present invention is to provide a heating evaporation device in which a bottle equipped with a liquid-absorbing core can be easily taken in and out of the device body, and which is less likely to be damaged. A second object of the present invention is to provide a heating evaporation device that can heat a liquid absorbent core well and evaporate liquid well. The object of the present invention is to provide a bottle mounting part that allows a bottle to be taken in and out in a direction perpendicular to a core provided on the bottle, and a heating mechanism that can heat the core of the bottle mounted on the bottle mounting part. Further, the heating mechanism is provided with an opening in the bottle mounting movement direction so that the core can be positioned within the heating mechanism when the bottle is mounted on the bottle mounting section, and the heating mechanism is provided with an opening in the bottle mounting movement direction, and the heating mechanism A heating evaporation device that evaporates a liquid in a bottle by heating it with the heat of a heating mechanism transmitted from the heating element, and the heat transfer device that evaporates the liquid in the bottle by heating it with the heat of the heating mechanism, which transfers the heat from the heating element well to the heating mechanism located inside the opening. This is achieved by a heating evaporation device characterized by having an R structure.

【Example】

Figures 1 to 5 show one embodiment of the heating evaporation device according to the present invention, where Figure 1 is a plan view, Figure 2 is a side view, and Figure 3 is a side view.
The figure is a front view with the lid open, Figure 4 is a schematic perspective view of the main parts,
FIG. 5 is a schematic plan view of the main parts. In each figure, reference numeral 1 denotes a main body of the heating evaporation device, and a bottle insertion portion 4 consisting of a recessed portion conforming to the shape of a bottle 3 is formed in the front face portion 2 of the device main body 1. Ceiling part 5 of the device main body 1 above this bottle insertion part 4
protrudes forward and forms a semicircular eaves portion 6. A transpiration hole 7 located directly above the bottle insertion part 4 is formed in the ceiling part 5. A heating body 8 made of a material with good thermal conductivity is provided on the upper side of the bottle insertion part 4 so as to protrude forward. In a plan view viewed from above, the heating body 8 has a substantially U-shape having, for example, an opening 8a, and this U-shaped groove portion constitutes a liquid-absorbing wick insertion portion 9. The heating element 8 is heated by, for example, energizing the heating element T, such as a positive temperature coefficient thermistor element connected to the heating element 8, through the power cord 1o. Inside the heating body 8, as shown in FIG. 5, a material 8s having a thermal conductivity higher than that of the heating body 8 is provided so as to be inclined inward at the opening 8alpl. In other words, since a heat transfer mechanism is configured in which heat from the heating element T is efficiently transferred to the heating element 8 located inside the opening 8a, the heat from the heating element T is heated more through the material 8S. However, since the material 8s is located further inside on the side of the opening 8a, more heat is supplied and heated at the position inside the heating element 8. . Front section 2 of the device main body 1. On the upper side, there is provided a front door 11 whose left side edge is attached to the main body 1 of the apparatus by a hinge member, and when the front door 11 is closed, the bottle 3 is inserted into the bottle insertion part. I try not to go beyond 4. In addition, there is a hook part 12 on the right edge of the front door 11.
is provided, and when the front door 11 is closed, the latch part 12 is inserted and locked into the latch hole 13 of the front part 2 of the device main body 1,
It is now locked. The bottle 3 is filled with a transpiring chemical liquid such as an insecticidal liquid for insecticidal purposes, an aromatic liquid for aromatic purposes, etc., and a liquid-absorbing wick for evaporating the chemical liquid upward from the mouth portion 3a of the bottle. 14 is made to protrude. Next, the operation of the heating evaporation device configured as described above will be explained. Insert the bottle 3 into the bottle insertion part 4 of the device main body 1. In this case, first open the front door 11 and open the liquid absorbent core 1 of the bottle 3.
The bottle 3 is inserted horizontally so that the liquid absorbent wick insertion portion 9 of the heating element 8 is located at the liquid absorbing wick insertion portion 9 of the heating element 8. Therefore, since the bottle 3 equipped with the liquid absorbent wick 14 can be taken in and out of the device main body 1 in a substantially horizontal direction, it is easy to attach (and remove) the bottle 3, and the liquid absorbent wick 14 can be removed when setting the bottle. There is no interference with the heating body 8 and the device main body 1, and damage to the liquid absorbent core 14 is prevented. Further, when inserting the bottle 3 into the bottle insertion part 4 of the device main body 1, there is no need to tilt or rotate the bottle 3.
Therefore, the medicinal solution in the bottle 3 will not be spilled. Next, the front door 11 is closed. In this state, when the positive temperature coefficient thermistor element is energized to heat the heating body 8, the liquid absorption core 14 is thereby heated, and the evaporated liquid is evaporated and released into the atmosphere from the evaporation hole 7. During this heating and evaporation, the liquid absorbent core 14 is heated almost uniformly from its surroundings. That is, since the heating body 8 is provided with an opening 8a through which the liquid absorbing wick 14 enters, there is no heating body on this side of the opening 8a, so although the heating rate is small accordingly, the opening 8a A material 8a having a thermal conductivity higher than that of the heating body by being inclined inward on the 8a side.
Since a heat transfer mechanism is constructed in which the heat from the heating element T is transferred well to the heating element at the position inside the opening 8a, the opening 8a is located inside the heating element 8.
The side becomes more heated, as if to compensate for the lack of a heating element on the side of the opening 8a, and the difference in temperature distribution decreases accordingly, and the liquid absorbent wick 14 is heated almost uniformly from the surroundings. It is. Incidentally, even if the width of the opening 8a (!ll) is increased, it is possible to compensate for the lack of a heating element on the side of the opening 8a, but if it is widened inward, the opening of the opening 8a The dimensions become narrower, which not only makes it difficult to insert the bottle 3, but also increases the risk of damaging the liquid absorbent wick 14 during insertion.Furthermore, if it is spread outward, the heating effect will be that bad, and the opening will be difficult. Even if the width dimension of the portion 8a side is increased either inward or outward, such a technique is inferior to the present invention. [Effect] The heating transpiration device according to the present invention crosses the core provided in the bottle. A bottle mounting section is provided that allows the bottle to be inserted or removed in any direction, and a heating mechanism that can heat the core of the bottle mounted on the bottle mounting section is provided. The heating mechanism is provided with an opening in the direction of movement of the bottle so that the wick can be positioned within the heating area, and the wick inside the bottle is heated by the heat of the heating mechanism transmitted from the heating element. The heating evaporation device for evaporating liquid is configured with a heat transfer mechanism that efficiently transfers heat from the heating element to the heating mechanism located inside the opening, so that it is easy to insert and remove a bottle equipped with a core into and out of the device body. This can be done, for example, from a horizontal direction, which has excellent workability, and the core is less likely to be damaged when setting the bottle.Furthermore, the heating mechanism is provided with an opening for the core to enter. Although the heating rate in that part is correspondingly small, we have constructed a heat transfer unit that efficiently transfers the heat from the heating element to the heating mechanism located inside the opening, so it is as if there is no heating mechanism on the opening side. This makes up for the difference in temperature distribution, which means that the core is heated almost uniformly from its surroundings, which results in excellent heating to the core and good evaporation of the liquid. It has the following features.
