Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic fire extinguishing mechanism that is incorporated into combustion appliances used for lighting and the like to prevent fire accidents.

Conventionally, small-scale combustion appliances such as oil lamps have not been equipped with fire prevention devices, and if the lamp falls over, it can immediately lead to a fire accident.

It has long been desired to install fire prevention devices on such small-scale combustion appliances, but since the combustion appliances themselves are small and there is little room for installing fire prevention devices, and they are also cheap, it is difficult to install fire prevention devices on these small-scale combustion appliances. Developing a fire prevention device for combustion appliances was a difficult problem due to limitations such as scale and price.

Therefore, the present invention was invented in view of the above-mentioned situation, and its purpose is to erect a cylindrical body on a disc made of a ferromagnetic material or a material containing a ferromagnetic material, and By supporting the flame, when a combustion appliance such as an oil lamp is tilted, the disc floats up, approaches the magnet and is attracted, and the cylinder covers the flame and extinguishes it. The present invention provides an automatic fire extinguishing mechanism that can be easily incorporated into combustion appliances.

Hereinafter, one embodiment will be described based on the drawings. FIG. 1 shows a candle-shaped lamp A incorporating an automatic extinguishing mechanism according to the present invention.

In this device, a liquid fuel such as rapeseed oil, salad oil, kerosene, or alcohol is stored in a candle-shaped container 1, and an ignition part 2 is fitted into the container.

The ignition section 2 includes a lid 3, a fire extinguisher 4, a spring 5 for elastically supporting the fire extinguisher 4, a welding core 8, and a support base 6.

The support stand 6 is cylindrical in shape and has a molten core support tube 6a extending through the center of the bottom surface 6b.

A groove is provided in the inner wall of the support cylinder 6a, and a spring 7 that clamps the molten core 8 is fitted into the groove.

The tip of the support tube 6a is rounded and tapered to prevent soot from coming out.

The above-mentioned fire extinguisher 4 also has a cylinder 4b inserted through the center of a disc 4a, and the cylinder 4b is loosely fitted to the outside of the support cylinder 6a, so that the fire extinguisher 4 can be moved up and down along the support cylinder 6a. It is a dynamic configuration.

The disc 4a moves up and down without contacting the side surface 6c of the support base 6.

At the time of lighting, the tip of the cylinder 4b is located at a slightly higher position than the tip of the support tube 6a.

The disk 4a is made of a ferromagnetic material such as iron or nickel, or made of plastic, rubber, or the like containing a ferromagnetic material.

The material of the cylindrical body 4b is preferably brass, copper, etc., which have high thermal conductivity, and when these metals are used, liquid fuel can be sucked up well.

In addition, in order to improve air circulation, support tubes 6a and 1 are provided.
A ventilation hole is provided in the body 4b.

In order to further improve air circulation, the ventilation hole of the cylinder body 4b located on the outside is provided with a groove at the height where the ventilation hole of the support cylinder 6a is provided, and a groove is bored deep into the groove. There is.

Although it is desirable that the support M6a and the cylindrical body 4b have ventilation holes, they may not be provided.

The periphery of the upper plate of the lid body 3 forms a flange, and the flange forms a flange of the container 1.
The lid 3 and the container 1 form a continuous curved surface.

The side wall 3b of the lid 3 is rounded so as to fit tightly into the container 1.

On the other hand, a hole 3a is bored in the center of the lid 3, and the upper ends of the support cylinder 6a and the cylinder 4b protrude from the hole 3a.

Further, an annular step 3c is provided on the inner peripheral edge of the side wall of the lid, and the support 6 is suspended from the lid 3 by contacting the collar 9 of the support stand with the step 3c and the side wall 3b. Fixed in state.

When the candle-shaped light fixture is tilted, the weight of the fire extinguisher 4 is not fully applied to the spring 5, so the spring 5 expands and pushes up the disc 4a. The disk 4a approaches the magnet 10 a little and is attracted to the magnet 10.

As a result, the fire extinguisher 4 moves upward along the support tube 6c, and the tube body 4b covers the molten core 8 protruding from the tip of the support tube 6a.
fire burns out.

This mechanism is an automatic fire extinguishing mechanism that is a feature of the present invention.

The angle of inclination of the light at which the fire extinguisher 4 operates can be arbitrarily set by changing the magnetic force of the magnet 10, the spring 5, and the weight of the fire extinguisher 4.

The automatic fire extinguishing mechanism of the present invention can be incorporated into various combustion appliances.

The embodiment shown in FIG. 6 is a light fixture that is fitted into the mouth of a liquor bottle 11 or the like, and a locking part is provided on the side surface of the fuel container 1 so that it can be fixed to the mouth of the bottle.

In the embodiment shown in FIG. 6, a stepped portion is provided as a locking portion, but a collar may be provided in addition, or a rubber locking tool may be used without providing a locking portion.

When the liquor bottle 11 etc. is empty, if you remove the ignition part 2 from the fuel container 1 and insert the ignition part 2 into the liquor bottle 11 etc. filled with liquid fuel again, it will last a long time without refilling the liquid fuel. You can turn on the time lamp.

Furthermore, the automatic fire extinguishing mechanism of the present invention can be incorporated into combustion appliances that utilize gaseous fuel.

A fire spout is fitted to the upper end of the support surface, the support cylinder is erected on a support stand, the fire extinguisher 4 is resiliently supported on the support stand, and the support cylinder is loosely fitted into the cylinder body 4b of the fire extinguisher 4. , by fitting the lid 3 to the support base and fitting the ignition part, which is provided with an on-off valve and a flow rate regulating valve in the gas flow path, to the gas cylinder,
It is possible to produce gas-burning appliances with automatic fire extinguishing mechanisms.

As shown in the above, the automatic fire extinguishing mechanism of the present invention is characterized in that it can be easily incorporated into small-scale combustors.

The present invention has a novel configuration and its practical effects are significant.
