Description

[Detailed description of the device] [Industrial applications]

The present invention relates to a heating evaporation device that heats and evaporates a chemical liquid such as a fragrance, an insecticide, or an antibacterial agent.

[Prior art and its problems]

As a heating evaporation device for heating and evaporating a chemical liquid such as a fragrance, an insecticide, or an antibacterial agent, for example, as described in Japanese Utility Model Laid-Open No. 58-45670, a bottle is placed on the bottom cover and a bottomless cylinder type with a lid is attached. The bottom lid of the main body of the above is fitted, or as described in JP-B-44-8361, the bolt is inserted from the bottom side of the bottomless cylindrical body with the lid, and the mouth of the bolt is inserted. A screwed part arrives at the main body, or as described in Japanese Utility Model Laid-Open No. 63-84240, a liquid medicine absorbed by heating an absorbent core partially immersed in the liquid medicine of a bottle. In a heating evaporation device for evaporating, a bottle insertion part that can put the bottle in and out of the device in a substantially horizontal direction is provided in the device body, a heating element is provided on the upper side of the bottle insertion part, and the liquid absorption core of the bottle is provided in the heating element. A substantially U-shaped flat surface that can be taken in and out from a substantially horizontal direction Having a configuration of wick insertion portion have been proposed. By the way, it has been known that these heating evaporation devices have a problem that the chemical liquid in the bottle leaks out when they are accidentally tumbled. In other words, these heating evaporation devices fall down when a force is applied from the side, because the lower surface of the device body is flat,
It has become clear that there is a problem that the drug solution in the bottle leaks out. In particular, when the heating evaporation device is, for example, an electric mosquito trap, it is used in a dark place, so it may inadvertently be overturned. The mouth lie down, and the liquid medicine gradually leaks. Therefore, in order to deal with such a problem, it has been proposed to cover the opening of the container with a sheet that is permeable to vapor but impermeable to liquid like a fine porous polymer sheet. However, a polymer sheet capable of exerting such an effect is expensive and cannot be practically used as a product like an electric mosquito trap. Further, a container has been proposed (Japanese Utility Model Laid-Open No. 62-111034) in which the shape of the container is devised so that the drug solution does not leak and leak to the bottom even if it is accidentally tumbled. However, also in this case, when the amount of the chemical liquid filled in the container is small, although the problem of liquid leakage at the time of falling is solved, when the amount of the chemical liquid filled in the container is large, The problem of liquid leakage when falling is not solved. Further, in any of these cases, a shock is applied to the core material when the core falls, so that the core material may be broken.

[Means for solving problems]

A first object of the present invention is to provide a heating evaporation device which does not have a problem of liquid leakage even when a tipping force is applied. A second object of the present invention is to provide a heating evaporation device at low cost. A third object of the present invention is to provide a heating evaporation device in which the core material does not break even if it is turned over. The object of the present invention is a heating evaporation device comprising a container for containing a chemical liquid, a core material for absorbing the chemical liquid in the container, and a heating mechanism for heating the core material. Has a center of gravity in the lower part, and the outer surface of the bottom side of the main body of the heating evaporation device is formed into a convex curved surface so that it can be restored naturally even if it is fallen down. Achieved by the evaporation device. That is, if the lower part of the main body of the device is formed into a curved surface so that it is a part of a sphere, and a weight such as lead is arranged in the lower part, this product has a low center of gravity, a comfortable sitting, and a rising position. As it becomes like a small juvenile, even if it is accidentally tumbled, it will immediately return to its original normal state, so there is no need to use expensive polymer sheets, and chemicals will not leak out, and transpiration will occur. The effect does not decrease, and since the shock is less likely to be applied, the core material is hard to break.

【Example】

FIG. 1 is a sectional view showing one embodiment of a heating evaporation device according to the present invention. In the figure, reference numeral 1 denotes an outer frame case that constitutes the main body of the heating evaporation device A, and a lower surface 2 of the outer frame case 1 is formed into a curved surface. Reference numeral 3 denotes a weight made of a material having a large specific gravity such as lead, and the weight 3 is arranged at the tip of the lower surface portion 2 of the outer frame case 1, and is attached to the outer frame case 1 in FIG. Even if the force in the direction of the arrow acts and it is tilted, the outer frame case 1 is constructed so that it rises up and restores its original state like a Koboshi. It should be noted that, when the outer frame case 1 is tilted by the force in the direction of the arrow in FIG. It is configured to restore to the state of. Reference numeral 4 denotes a bottle for filling a chemical liquid such as an aromatic agent, an insecticide or an insect repellent, and the bottle 4 is configured to be set and fixed to the bottle mounting portion of the outer frame case 1. Reference numeral 5 denotes a porous core material that stands upright in the bottle 4 for absorbing a chemical liquid. Reference numeral 6 denotes a lid body provided so as to cover the upper opening of the outer frame case 1, and a hole 7 is formed in a top plate portion of the lid body 6 so that the heated and evaporated chemical liquid is released into the atmosphere. There is. Reference numeral 8 denotes a ring-shaped heating body attached to the lid body 6. When the lid body 6 is arranged with respect to the outer frame case 1, the core material 5 is located in the center hole of the ring-shaped heating body 8. It is like this. Next, the operation of the heating evaporation device A configured as described above will be described. First, the lid 6 is opened, and the bottle 4 is attached and fixed to the bottle mounting / attaching portion of the outer frame case 1. The mounting and fixing work of the bottle 4 is performed in the vertical direction of the outer frame case 1, but this is the front-back direction (horizontal direction).
It may be configured to be done by hand. Next, the lid 6 is closed. In this state, when the positive temperature coefficient thermistor element is energized to heat the heating element 8, the core material 5 is heated by this, and the chemical solution in the bottle 4 is evaporated and released into the atmosphere through the hole 7. By the way, even if the outer frame case 1 is tilted by the force in the direction of the arrow in FIG.
The outer case 1 is in its original state (first
Restore the state shown in the figure). Therefore, a force in the lateral direction is applied to some beat to bring it down, and the restoration is performed immediately so that the chemical liquid in the bottle 4 is not spilled and the surrounding area is not polluted. Moreover, since the means for preventing the problem of liquid leakage even when it is turned over has an extremely simple structure, the problem of increasing the cost of the heating evaporation device A does not occur. Moreover, there is no problem that the transpiration effect decreases. In addition, even if it is overturned, shock is not likely to be applied at this time, so if it falls, a shock acts as a reaction at that time, and this shock is transmitted to the core material and the core material may be broken. However, since the present invention does not have a fall shock, there is no risk of the core material 5 breaking.
