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 the heating element.
The mosquito repellent mat is heated to about 20° C., and insecticidal gas generated from the mosquito repellent mat placed on the heating element and heated by the heating element stops or weakens the activity of mosquitoes.

Therefore, a power source is required to heat the mosquito repellent mat, 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, in which the 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 conventionally proposed hand warmer that can be used as a mosquito repellent has a structure in which the hand warmer portion is heated as is, and 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 mat part, and a large amount of heat is directly released to the outside, resulting in extremely poor thermal efficiency.

This invention solves the problems with the previously proposed hand warmers, and makes it possible to realize a mosquito repellent hand warmer that can also be used as a mosquito repellent and has extremely high operational thermal efficiency.

In the mosquito repellent pocket heater of this invention, a fitting made of a poor conductor of heat can be detachably attached to the periphery of the opening to the fuel storage tank, which has an opening through which the fuel gas that has turned into vapor is released. It is considered to be a composition.

A platinum cotton material that generates heat by igniting the fuel gas from the opening is attached to this fixture so as to cover the opening, and a mosquito repellent mat can be removably attached to the fixture by covering this fixture. A holder is attached, and the pocket warmer lid is attached to the fuel storage tank so as to cover the holder.

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

FIG. 1 is a cross-sectional view showing the structure of an embodiment of the mosquito repellent pocket warmer of this invention, in which a base body 11 made of a heat conductive material such as a substantially circular plate-shaped metal is provided, and a structure that covers the base body 11 is provided. The tank lid 12 is fixed to the base body 11 at its peripheral edge by, for example, welding.

The base body 11 and the tank lid 12 constitute a fuel storage tank 13.

A substantially circular opening 14 is formed in the center of the tank lid 12, and at the periphery of this opening 14, the end of the tank lid 12 is bent at right angles to the surface of the opening 14 to form a peripheral edge 12-E. .

The fuel storage tank 13 is filled with a fuel-impregnated material 15 such as cotton, and this fuel-impregnated material 15 is impregnated with a volatile fuel 16 such as benzene.

The fitting 17 is made of, for example, a hard synthetic resin material that has good heat resistance and low thermal conductivity, and this fitting 17 is attached to the tank lid 1.
It is fitted and attached to the peripheral edge part 12-E of No.2.

This fitting 17 is formed in a substantially annular shape, and its inner diameter is set slightly larger than the outer diameter of the peripheral edge 12-E of the tank lid 12. It is configured to be detachable at will.

This fixture 17 is used when the pocket warmer is used as a mosquito repellent.

A stepped portion 18 is formed on the inner circumferential surface of the end of the fitting 17 remote from the tank lid 12 to enlarge the inner diameter of the inner circumferential surface.

A circular metal rod body 19 can be fitted and disposed in this stepped portion 18.
is formed, and the rope body 19 is attached to the fixture 17 by fitting at this stepped portion 18 .

A substantially annular platinum cotton body 20 is mounted and fixed on this rope body 19.

The end of the fitting 17 on the side of the tank lid 12 is bent at right angles to the side surface of the fitting 17 to form a stepped portion 21.

A holder 22 is formed of a material having high thermal conductivity such as metal and is detachably attached to the fixture 17 so as to cover the fixture 17 .

This holder 22 is formed into a substantially cylindrical shape with one side open, and its inner diameter is set to be slightly larger than the outer diameter of the fixture 17.

Therefore, when the holder 22 is fitted to the outside of the fixture 17, its end portion is located on the stepped portion 21, and the holder 22 is fitted onto the fixture 17.

A recess 23 is formed in the closed surface of the holder 22, and the recess 23 is formed in a shape into which a mosquito repellent mat 24 can be fitted and attached.

A pocket warmer lid 25 is attached to the fuel storage tank 13 so as to cover the holder 23 to which the mosquito repellent mat 24 is attached.

In the embodiment, for example, a metal pocket warmer cover 25 is formed into a substantially circular plate shape, and the peripheral edge of the pocket warmer cover 25 is formed by the tank cover 1.
It is formed so that it can be fitted to the peripheral edge of 2.

Therefore, the pocket warmer lid 25 is held at its peripheral edge by the tank lid 1.
2, the pocket warmer lid 25 is fitted and fixed to the tank lid 12.

Further, when the pocket warmer cover 25 is separated from the tank cover 12 at its peripheral edge, the pocket warmer cover 25 is separated from the tank cover 12.
removed from the

The structure of this portion is not limited to that shown in the embodiment, and may be, for example, a structure in which one peripheral end of the pocket warmer cover 25 is attached to the tank cover 12 with a hinge.

When the pocket warmer is used as a mosquito repellent, the fitting 17 is fitted and fixed to the peripheral edge 12-E of the tank lid 12, and the vapor released from the opening 14 is placed on the platinum cotton body 20 using, for example, a phosphorus size. ignites the fuel gas.

The holder 22 is fitted and fixed to the fixture 17, and the mosquito repellent mat 24 is attached to the recess 23 on the holder 22. In this state, the pocket warmer lid 25 is fitted to the fuel storage tank 13, and the mosquito repellent mat 24 is fitted. 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 holder 22.
Small holes 25W+ to 25-W are formed in the pocket warmer lid 25 through which insecticidal gas is emitted from the mosquito repellent mat 24 by heating the upper mosquito repellent mat 24.

This insecticidal gas is released and the mosquito repellent function is demonstrated.

As the mosquito repellent mat 24, for example, one that generates insecticidal gas such as di-d-T2O-allethrin (pyrethroid) is used.

Since the fixture 17 is made of a heat insulating material, the heat generated by the platinum cotton body 20 during this mosquito trapping operation is not dissipated to the side of the fuel storage tank 13 of the pocket warmer, resulting in an efficient mosquito trap with less heat loss. The function is demonstrated and the duration of the mosquito repellent effect is significantly extended.

When used as a pocket warmer, the fitting 17 is replaced with a fitting 30 dedicated to the pocket warmer.

As shown in FIG. 2, the hand warmer mount 30 is made of a metal material with high thermal conductivity and is formed into a substantially annular shape.

A rope body 19 is fixedly disposed at an intermediate position of this toric body at right angles to the circumferential surface of the toric body, and a platinum cotton body 20 is mounted on this rope body 19.
is installed.

The inner diameter of the pocket warmer attachment 30 is the same as the peripheral edge 12 of the tank lid 12.
- It is set slightly larger than the outer diameter of E.

When used as a pocket warmer, the holder 22 and the attachment 1
7 from the tank lid 12, attach the pocket warmer attachment 30 to the tank lid 12, and remove the platinum cotton body 2 on the surface.
The vaporized gaseous fuel is ignited in the zero section.

In this case, since the hand warmer attachment 30 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 hand warmer, making the entire hand warmer more efficient. It heats up well and exhibits 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 effectively released in the direction of the mosquito repellent mat 24, so that the hand warmer is not heated unnecessarily, and the hand warmer lid 25 is attached. Because of this, the heat dissipation loss field is extremely small and the mosquito repellent effect with high thermal efficiency is maintained for a long time.

When used as a hand warmer, simply by replacing the fitting 17 with the hand warmer-dedicated fitting 30, the entire hand warmer can be effectively heated and a hand warmer with high heating efficiency can be realized.

This invented mosquito repellent stove does not require a power source and can be used for camping, camping, etc.
It is extremely convenient and can be easily used outdoors as a mosquito repellent while hiking, fishing, etc.

In the description of the embodiment, a case in which a phosphor is used to ignite vaporous gaseous fuel has been taken up, but it is also possible to realize a structure in which a battery ignition mechanism is incorporated into the hand warmer.

Furthermore, if the fixture 17 is made of a material with high thermal conductivity, it can function as a pocket warmer and a mosquito repellent at the same time. However, it is efficient to use when working at low temperatures while keeping your body warm with a hand warmer.

As explained in detail above, this invention has a simple and robust structure and can function as a pocket warmer or a mosquito repellent under highly efficient operating conditions by simply replacing the fixture and holder. A mosquito repellent pocket warmer that can be realized can be provided.
