[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating and evaporating apparatus for evaporating insecticides, fragrances and the like using an electric heating type heating element.

[0002]

2. Description of the Related Art Conventionally, a heat evaporation apparatus has been used to evaporate insecticides and the like. The heating and evaporating device evaporates the effective component of the chemical solution by sucking the chemical solution in the medical solution container housed in the container with the liquid absorbing core and appropriately heating the liquid absorbing core with an electric heating type heating element. is there.

[0003]

There is a demand for a highly versatile heating and evaporating apparatus which can be used in various ways (for example, more than 20 ways). For example, depending on the size of the space to be applied and the target pest, air concentration,
What can change the amount of transpiration, the amount of volatilization, etc. is demanded.
In addition, it is also possible to set the extent to which the effect can be obtained, such as preventing insect invasion without having to kill insects, long-lasting, or immediate effect without long-lasting, according to the user's preference. It is convenient if possible. However, in the conventional heat evaporation apparatus, the adjustment range of the evaporation amount and the evaporation amount is insufficient, the types of usable chemicals are limited, and it has not been possible to meet the needs of the user.

The present invention has been made in view of such circumstances, and it is an object of the present invention to provide a heating and evaporating apparatus whose effect can be adjusted over a sufficiently wide range according to the use condition.

[0005]

The object of the present invention described above can be achieved by the following constitution. In a heating and vaporizing device in which a liquid medicine container is housed in a container, and a liquid absorbing wick protruding upward from the liquid medicine container is heated by a heating element provided in the container to evaporate the liquid medicine sucked into the liquid absorbing core. Heating temperature control means for changing the temperature of the heating element to a plurality of ranges; and adjusting a vertical position of at least one of the heating element and the chemical solution container in the container to increase a heated area of the liquid absorbing core. A heating and evaporating apparatus comprising: a changeable heated area changing means. The heating and evaporating apparatus according to the above, wherein a contact portion that comes into contact with the liquid medicine container at an uppermost end position of the liquid medicine container is provided in the body. The heating and evaporating apparatus according to any of the above or the above, further comprising a position recognition unit configured to recognize a position of at least one of the heating element and the chemical solution container in the container. The heating and evaporating apparatus according to any one of the above (1) to (4), further comprising a temperature recognition unit configured to recognize a temperature of the heating element. The heat evaporation device according to any one of the above-described items, wherein any one of a plurality of drug solution containers each containing a drug solution having a different concentration can be stored in the container.

According to the above arrangement, the amount of evaporation, the amount of evaporation, the concentration, and the like can be adjusted by both the heating temperature control means and the heated area changing means. Therefore, the effect can be adjusted over a sufficiently wide range according to the use situation, and it can respond to various needs of the user.
For example, it can be used effectively in rooms of different sizes, campers and tents, closets, kennels, etc., and over a long time, at a certain time, initially, finally,
Alternatively, the timing at which the effect is exerted, such as at an arbitrary time, can be adjusted. By adjusting both the heating temperature control means and the heated area changing means, it became possible to exhibit such a multi-function. According to the above configuration,
It is possible to quickly obtain a state in which the heated area of the absorbent core is increased. Therefore, when the amount of transpiration needs to be rapidly increased, the amount of transpiration can be appropriately increased quickly and easily with this configuration. According to the above configuration, the position of the heating element and / or the chemical solution container in the container can be accurately grasped. Further, according to the above configuration, the temperature of the heating element or the set temperature can be accurately grasped. Therefore, it is possible to reliably prevent erroneous setting of the positions of the heating element and the chemical solution container and the temperature of the heating element. According to the above configuration, the adjustment range of the effect can be further expanded by changing the concentration of the drug solution. For example, if the concentration is high, it can be used as a smoking agent (a substance that evaporates a high concentration of the drug in a short time to eliminate cockroaches, mites, fleas, etc.), and if the concentration is low, it can be used as a mosquito blood-sucking inhibitor or Iga-koiga. Can be used as an insect repellent.
Further, by changing the concentration of the chemical solution, the service life of the chemical solution container can be set to 30 days, 60 days, 90 days, or the like.

In the present invention, as the heating element, for example, a positive temperature coefficient thermistor (PTC thermistor) or an element using a nichrome wire as a heating element can be adopted. A heat transfer element made of metal or the like may be connected to the heat generation element or a heat generation container containing the heat generation element, and the liquid transfer core may be heated by the heat transfer member. As the heating temperature control means, an electronic control device with a built-in microcomputer can be used. Further, a heating element having a ring shape surrounding the liquid absorption core and having an adjustable inner diameter may be used. Although not particularly limited, the heating temperature control means can set the surface temperature of the heating element to about 40 to 200 ° C. and the surface temperature of the liquid absorbing core to 30 to 185 ° C. Further, by using a heating element (for example, a transformer-less heating element described in Japanese Patent Application Laid-Open No. 6-349566) in which a heating temperature does not significantly change with respect to a change in applied voltage, as a PTC thermistor, Even if the commercial power supply changes in the range of 100 to 220 V, good heat generation characteristics can be obtained.

In the present invention, examples of the absorbent core include felt, cotton, pulp, non-woven fabric, asbestos, inorganic molding materials, etc., and include felt cores (sintered cores made of resin such as polyacryl). ), Unfired core (ceramic core), pulp core or inorganic molded core is preferably used.
As the chemical liquid container, for example, a liquid container having a small-diameter cylindrical portion provided above a large-diameter cylindrical portion having a bottom and a liquid-absorbing core protruding from the small-diameter cylindrical portion can be used. As the means for changing the heated area of the chemical solution container, in addition to manually moving the medical solution container to a predetermined position in the body, automatically moving the chemical solution container to a predetermined position in the body, and generating heat in the body A device that moves the body manually or automatically may be employed.
