Description

[Detailed Description of the Invention] [Industrial field of application] This device is designed to suck up heat-transpiration agents such as insecticides and bactericides contained in the main body with a liquid-wicking core provided in the main body.
The present invention relates to a heating evaporator capable of evaporating a heating evaporation solvent by heating an absorbent core with an appropriate heating device.

[Prior Art] Conventionally, in this type of heating vaporizer, a full-scale open shovel 60-1258
There is one described in Japanese Patent Publication No. 76. This one is
The liquid-wicking core was press-fitted into and inserted into a tubular portion that was hung from the lid of the liquid medicine container to hold the liquid-wicking core in a stable and reliable manner.

[Problems to be solved by the device]

However, in the above conventional heating vaporizer, since the liquid absorbent core is held on the inner surface of the tubular portion in order to stably and reliably hold the liquid absorbent core, when press-fitting and inserting into the tubular portion of the liquid absorbent core. However, there is a problem that a large amount of friction is generated in the tube and it is difficult to insert the liquid absorbent core into the tubular portion.

Therefore, the heating vaporizer of the present invention has been made for the purpose of solving the problems of the conventional heating vaporizer.

[Means for Solving the Problems]

Therefore, in this invention, a closing body is provided at the mouth of the main body containing the agent for heat evaporation, the closing body is provided with a tubular portion surrounding the liquid absorption core, and the inner surface of the tubular portion is provided with a small portion. The protrusion is formed to be inscribed in the liquid absorbent core, and the lower part of the tubular portion is inscribed in the liquid absorbent core.

Further, a packing may be provided below the tubular portion for implementation.

In this invention, as the heat-transpiration agent, any of insecticides, bactericides, acaricides, repellents, aromatics, deodorants, antifungal agents and the like can be used. These agents are used as they are or in addition to solvents such as silicone oil and kerosene, and further added with various additives such as synergists, antioxidants and volatilization rate regulators.

In this invention, examples of the closing body include those having a form such as a lid and a stopper, and are not limited as long as they have a closing function.

In the present invention, the liquid absorbent core may be made of any organic or inorganic material, and specific examples thereof include the following. For example, felt core, unglazed core, asbestos core,
Porcelain porous, glass fiber, inorganic fiber such as asbestos hardened with a binder such as gypsum and bentonite, glass powder, kaolin, activated clay, talc, diatomaceous earth, clay, perlite, bentonite, alumina, silica,
Alumina silica, titanium, one or more kinds of mineral powder such as calcined powder of vitreous volcanic rock and calcined powder of vitreous volcanic ash or a mixture of these powders with wood powder, charcoal powder, activated carbon, etc., for example, dextrin, starch, For example, it is hardened with a binder such as silicone resin, fluororesin, arabic rubber, carboxymethyl cellulose, and synthetic glue. As a particularly preferable liquid absorbent core, 100 parts by weight of the mineral powder and wood powder or a mixture of the wood powder and carbon powder and / or activated carbon up to an equal weight of 10 to 30 is mixed.
It is produced by mixing 0 part by weight, blending 5 to 25 parts by weight of the total liquid absorption core with the binder, adding water to them, kneading, extrusion-molding, and drying. Is mentioned. This liquid-wicking core has a liquid-absorbing rate of 1 to 4
Desirably, it is 0 hour, preferably 8 to 21 hours.
Such a liquid absorption rate means that a liquid absorption core with a diameter of 7 mm and a length of 70 mm is placed in the n-paraffin liquid at a liquid temperature of 25 ° C.
It means a value obtained by immersing the liquid absorption core up to 5 mm and measuring the time until the n-paraffin reaches the apex of the absorbent core. Further, if necessary, a dye such as malachite green, sorbic acid and salts thereof, an antifungal agent such as dehydroacetic acid, and the like can be added to the liquid absorbent core.

In the present invention, the body may be of any size, shape, material, etc., as long as it can contain the chemical for heat evaporation. In addition, when the internal pressure of the main body rises morphologically,
A bellows type container may be made of a flexible material capable of absorbing the internal pressure.

[Operation] The present invention has the following operations due to the above means.

In this invention, since the small protrusions are formed on the inner surface of the tubular portion, the contact area between the tubular portion and the liquid absorbent core becomes point contact, and the liquid absorbent core is inserted into the tubular portion. The frictional resistance becomes smaller.

The liquid-wicking core held in the tubular portion functions as a plug of the main body containing the agent for heating and evaporation.

Further, as described in claim 2, if the packing is provided at the lower portion of the tubular portion, the gap between the liquid core and the tubular portion becomes smaller and the plug functions more reliably.

〔Example〕

Hereinafter, the structure of the heating vaporizer of the present invention will be described with reference to the drawings showing examples.

FIG. 1 is a vertical cross-sectional view of the heating vaporizer of the present invention.

(1) is a main body containing a heat-transpiration agent (2) therein, and a mouth (1a) of this (1) is closed by a closing body (3). A cylindrical portion (5) surrounding the liquid absorbent core (4) is vertically provided on the closing body (3), and a small projection (6) is formed on at least a part of the inner surface of the cylindrical portion (5). Is formed and is inscribed in the liquid absorbent core (4) (see FIG. 3). Further, the lower portion (5a) of the tubular portion (5) is inscribed in the liquid absorbent core (4).

FIG. 2 is a vertical sectional view showing another embodiment of the device of the tail.

What is shown in this embodiment is substantially the same as that shown in FIG. 1 except that a packing (7) is provided on the lower portion (5a) of the tubular portion (5). The packing (7) is a tubular part (5).
It can be provided as an integral part or a separate part in the lower part (5a).

The heating vaporizer of the present invention configured as described above is attached to an electric heating type heater as shown in the following, and the liquid absorption core (4)
By heating, the heating evaporation agent (2) contained in the main body (1) is evaporated.

As shown in FIG. 4, the electric heating type heater has a detachable bottom lid (8) at the bottom, and by removing the bottom lid (8), the heating vaporizer can be appropriately replaced. Has been done. The bottom lid (8) is provided with a flange portion (8a) on its peripheral edge and a recess (8b) for receiving the lower portion of the heating vaporizer in the center thereof. Further, a heater (10) for evaporating the heating evaporation agent (2) sucked up by the liquid absorption core (4) is provided in the main body (9) of the electric heating type heater. The heater (10) is of a cylindrical shape that surrounds the upper part of the liquid absorbent core (4) with a gap (11).

[Effect of device]

Since the heating vaporizer of the present invention is configured as described above, it has the following effects.

In this invention, since the contact area between the tubular part and the liquid absorbent core is small, the friction resistance when press-fitting and inserting the liquid absorbent core into the tubular part is small, so that the liquid absorbent core is inserted into the tubular part. Will be easier. In addition, since the liquid absorbent core is press-fitted and attached to the tubular portion, it is not only securely held, but also because the liquid absorbent core functions as a plug of the main body containing the heat evaporation agent, the main body is erroneously Even if you fold down, the heat evaporation agent will not spill out.

Further, according to the second aspect of the present invention, the packing provided at the lower portion of the tubular portion can seal the gap between the liquid absorbent core and the tubular portion, so that liquid leakage can be prevented more reliably.
