Description

[Detailed description of the invention] This invention relates to a mosquito repellent pocket burner that can also be used as a mosquito repellent.

Conventional electric mosquito repellents use a household power source to heat a heating element to around 120℃, and the insecticidal gas generated by the mosquito repellent mat placed on top of this heating element and heated by the heating element stops mosquito activity. or weaken its activity. Therefore, a power source is required to heat the mosquito repellent, and it cannot be used in a place without a power source.

This invention makes it possible to provide a mosquito repellent function to a hand warmer, and provides a mosquito repellent hand warmer that can function as a mosquito repellent without requiring a power source. BACKGROUND ART Hand warmers have been proposed in the past that have a structure in which a lid of the hand warmer can be removed and a mosquito repellent mat can be placed on the heating element of the hand warmer. However, this previously proposed pocket warmer that can be used as a mosquito repellent still heats the pocket warmer as it is.
Moreover, the structure is such that the mosquito repellent mat portion is exposed to the outside air. For this reason, the heat emitted from the heating element of the hand warmer part is used both to heat the hand warmer part and to heat the mosquito repellent part, and a large amount of heat is also directly released to the outside, resulting in extremely poor thermal efficiency.

This invention solves the various problems with the conventionally proposed hand warmers, and provides a mosquito repellent hand warmer that can also be used as a mosquito repellent, has good thermal efficiency in operation, and provides stable operation.

In the mosquito repellent pocket warmer of this invention, a fitting is detachably attached to the periphery of the opening of the fuel storage tank having an opening through which fuel vapor is released. A platinum cotton body is attached to this fixture so as to cover the opening of the fuel storage tank, and generates heat by igniting fuel vapor from the opening.

A holder is configured to be able to be detachably attached to this holder, and a mosquito repellent mat can be attached to the holder so as to cover the holder, and the holder can be rotated around its axis. Adjustment body can be attached freely. By rotating this adjustment body, the amount of air supplied to the platinum cotton body attached to the fixture via the holder can be adjusted. Furthermore, the mosquito repellent pocket warmer of the present invention has a structure in which a lid body is attached to the fuel storage tank so as to cover the adjustment body.

Hereinafter, the mosquito repellent pocket warmer of this invention will be explained in detail based on an embodiment thereof using the drawings.

The first fitting 17-1 is in contact with the end plate 21 of the first fitting 17-1 in the direction away from the tank lid 12.
A holder 22 is made of a material with high thermal conductivity such as metal and is detachably attached to the first fixture 17-1 so as to cover the first fixture 17-1. This holder 22 is formed into a substantially cylindrical shape with both opposing end surfaces being open faces, and its inner diameter is set slightly larger than the outer diameter on the communication hole 17-H side of the first fitting 17-1. Ru. Therefore, the retainer 22 is connected to the first fixture 17-1.
When the holder 22 is fitted to the outside of the communication hole 17-H side, the end thereof is located on the end plate 21, and the holder 22 is fitted to the first fitting 17-1.

A plurality of approximately rectangular windows 22-W1 and 22-W2 are formed on the side surface of the holder 22, and the holder 2
Step portions 35-1 and 35-2 are formed by cutting into the inner circumferential surfaces of the two inner circumferential surfaces at mutually opposing positions.
A metal rod-like body 36 having a rectangular outer shape is fitted and fixed across the step portions 35-1 and 35-2.
A mosquito repellent mat 24 is disposed on a rope 36 that is fitted and fixed to the stepped portions 35-1 and 35-2 of the holder 22. In this way, the adjusting body 38 is formed to be fitted onto the holder 22 with its inner circumferential surface facing the outer circumferential surface of the holder 22 to which the mosquito repellent mat 24 is attached. .

The adjustment body 38 is formed into a substantially cylindrical shape with both end surfaces being open faces, and a plurality of approximately rectangular windows 38-W-1, 38-W2 are formed on the circumferential surface of the adjustment body 38, one of which is open. Band-shaped holding pieces 39-1 and 39-2 are formed so as to straddle the open surface. The inner diameter of the inner circumferential surface of the adjusting body 38 is set to be slightly larger than the outer diameter of the outer circumferential surface of the holder 22.
The rod-like body 36 and the mosquito repellent mat 24 are fitted onto the outer circumferential surface of the holder 22, on which the mosquito repellent mat 24 is fixedly disposed, so that the inner circumferential surface thereof is in contact with the outer circumferential surface of the holder 22.

When the adjusting body 38 is rotated around the axis, the windows 22-W1, 2 formed on the peripheral surface of the holder 22 open.
The overlapping state of 2-W2... and the windows 38-W1, 38-W2... formed on the circumferential surface of the adjustment body 38 changes, and the holding tool for the platinum cotton body 20 attached to the fixture 17-1 changes. The amount of air supplied through the windows of 22 and regulator 38 changes. That is, when the adjusting body 38 is rotated with respect to the holder 22, the window 22

In proportion to this set window area, the fixture 1
The amount of air supplied to the platinum cotton body 20 attached to the air filter 7-1 is set.

When the adjusting body 38 is rotated with respect to the holder 22, the relative positions of the holding pieces 39-1 and 39-2 with respect to the mosquito repellent mat 24 change as shown in FIGS. 3 and 4. However, in any rotational position, these holding pieces 39-1 and 39-2 are configured to prevent the mosquito repellent mat 24 from falling off from the open surface.

The lid body 25 is fitted and attached to the fuel storage tank 13 so as to cover the adjustment body 38 . In this embodiment, for example, a metal lid body 25 is formed into a substantially circular dish shape, a peripheral edge of the lid body 25 is formed so as to be able to fit into a peripheral edge of the tank lid 12, and a large number of openings are formed on the surface of the lid body 25. was formed. Therefore, the lid body 2
5 is fitted and attached to the tank lid 12 at its peripheral edge, the lid body 25 is attached to the tank lid 12.
is installed and fixed. Moreover, when the lid body 25 is pulled away from the tank lid 12 at its peripheral edge, the lid body 25 is removed from the tank lid 12.

The structure of this part is not limited to that shown in the example.
For example, a structure may be adopted in which one end of the circumferential side of the lid body 25 is attached to the tank lid 12 with a groove.

When using the pocket warmer as a mosquito repellent, as explained above, the first fitting 17-1 is fitted and fixed to the peripheral edge 12-E of the tank lid 12, and the platinum cotton is attached using the adjacent size, for example. The vaporous fuel gas released from the opening 14 on the body 20 is ignited. The holder 22 is fitted and fixed to the first fixture 17-1, and the mosquito repellent mat 24 is attached to the holder 22 via the rope 36. In this state, the lid is attached to the fuel storage tank 13. 25 and cover the mosquito repellent mat 24 to cover the fuel storage tank 13.

By igniting the fuel gas, heat is generated using the platinum cotton body 20 as a medium, and the heat generated by this heat is transferred to the mosquito repellent mat 2 attached to the holder 22.
4 is heated, insecticidal gas is emitted from the mosquito repellent mat 24, and the small hole 25-W formed in the lid body 25 is heated.
This insecticidal gas is released from 1 to 25-Wn and exhibits its mosquito repelling function. As the mosquito repellent 24, for example, one that generates insecticidal gas such as d1-d-T80-allethrin (pyrethroid) is used.

Since the first fitting 17-1 is made of a heat insulating material, the heat generated by the platinum cotton body 20 during this mosquito repelling operation is not dissipated to the fuel storage tank 13 side of the pocket warmer, resulting in heat loss. It exhibits an efficient mosquito repelling function with less mosquito repellent, and the duration of the mosquito repelling effect is significantly extended.

Also, by rotating the adjustment body 38 with respect to the holder 22, the windows 22-W1, 22-W2, . . . formed on the circumference of the holder 22 and the windows 38 formed on the circumference of the adjustment body 38 are -W1, 38-W2, etc., it is possible to change the amount of air supplied to the platinum cotton body 20 and set the optimum heat generation conditions.

Generally, when used as a mosquito repellent, it is necessary to keep the heating temperature of the mosquito repellent mat 24 constant to ensure efficient release of insecticidal gas under stable heating conditions. However, the temperature, wind force, and humidity vary depending on the atmosphere in which the mosquito repellent pocket warmer is used, and there are also manufacturing irregularities in the platinum cotton body 20.
The heating conditions are not constant. Therefore, the adjustment body 38 is not present, and the platinum cotton body 20 is fixed to the fixture 17-1.
If the amount of air supplied cannot be adjusted, it is not possible to set the optimum combustion conditions. In this case, the mosquito repellent 24
The release of insecticidal gas may be completed, or, conversely, sufficient combustion conditions may not be set, resulting in incomplete release of insecticidal gas.

However, in the mosquito repellent pocket warmer of this invention, the holder 22
Rotate the adjustment body 38 against the mounting tool 17-
By adjusting the amount of air supplied to the platinum cotton body 20 fixed at 1, it is possible to always set optimal heating conditions in accordance with the usage atmosphere conditions.

When used as a pocket warmer, the first fitting 17
-1 is replaced with the second fixture 17-2. As shown in FIG. 5, the second fixture 30 is made of a metal material with high thermal conductivity and has a substantially annular shape. A rope body 19 is fixedly disposed at an intermediate position of the toric body at right angles to the circumferential surface of the toric body, and a platinum cotton body 20 is attached to the rope body 19. The inner diameter of the second fitting 17-2 is the circumferential edge 12-E of the tank lid 12.
It is set slightly larger than the outer diameter of.

When used as a pocket warmer, remove the holder 22 and the first fitting 17 from the tank lid 12, and attach the second fitting 17-2 to the tank lid 12.
is attached, and the vaporized gaseous fuel is ignited at the 20 portion of the platinum cotton body on its surface. In this case, since the second fitting 17-2 is made of a metal with high thermal conductivity, the heat generated by ignition using the platinum cotton body 20 as a medium is also released toward the fuel storage tank 13 of the pocket warmer. The entire body is heated efficiently, demonstrating the excellent heat retention efficiency of a pocket warmer.

In this way, according to this invention, when used as a mosquito repellent, the generated heat is transferred to the mosquito repellent 2.
The heat is effectively emitted in four directions so that the pocket warmer is not heated in vain, and since the lid body 25 is attached, heat dissipation loss is extremely small and a mosquito repelling effect with good thermal efficiency is maintained for a long time. In addition, when using it as a pocket warmer, the first fitting 17-1 is replaced with the second fitting 1.
7-2, the entire pocket warmer can be effectively heated and a pocket warmer with high heating efficiency can be realized. This invented mosquito repellent pocket heater does not require a power source and is extremely convenient as it can be easily used outdoors as a mosquito repellent when camping, hiking, fishing, etc.

In the description of the embodiment, an example in which a cylindrical body is used for igniting vaporous gaseous fuel has been discussed, but it is also possible to implement a structure in which a battery ignition mechanism is incorporated into the hand warmer. Furthermore, if the first fixture 17 is made of a material with high thermal conductivity, it is possible to simultaneously perform the functions of a pocket warmer and a mosquito repellent without replacing the fixture.For example, in a low-temperature atmosphere. It is efficient to use when working at low temperatures while keeping the body warm with a hand warmer while killing special pests that occur in the environment.

As explained in detail above, this invention has a simple and robust structure, and can function as a pocket warmer or a mosquito repellent by simply replacing the mount and holder under highly efficient operating conditions. It is possible to provide a mosquito repellent pocket warmer that can be realized in the following manner.
