As is well known, fire is not too dry and occurs naturally in forested mountains, but most fires or wildfires are caused by carelessness of users or hikers. And because it is very often generated by the gas supplied to each home, most of the human beings can be seen as a genius (天災).

In the event of a fire in various buildings, it is possible to extinguish relatively quickly with the cooperation of local fire departments and other civil defense personnel, but in the case of forest fires, it is impossible to enter vehicles, and the roads are also difficult to extinguish. In other words, it is easy to spread, and there are sometimes inexplicable problems such as casualties occurring during forest fire extinction and suppression.

In general, extinguishing powder type extinguishers are for extinguishing fires in the early stages of fire. There are various types of extinguishers that inject powder extinguishing agents by incombustible high-pressure gas (carbon dioxide, nitrogen). It is used in, but because the structure of the pressure gas cylinder must be provided inside the container of the fire extinguisher, the structure is complicated, the user's operation was also difficult.

In addition, since the extinguishing powder is pressure-filled, there is a risk of leakage of pressure during storage. As a result, the spraying distance of the extinguishing powder is shortened during actual use, which is a factor that may lower the extinguishing effect or threaten user safety.

In addition, the throwing fire extinguisher is known that throws the container itself at the point of fire to destroy the container and spread the powder extinguishing agent inside to exert a fire extinguishing function. Due to the carelessness of the product, there is a risk of unauthorized explosion, which lowers the reliability of the product.

Therefore, the present invention has been made to solve all the problems caused by the existing fire extinguisher as described above,

An object of the present invention can be configured as a portable small fire extinguisher can be easily applied to a variety of situations, easy operation and operation and light weight can provide convenience in handling, the directivity of the fire extinguishing powder Its purpose is to provide explosive injection type fire extinguishers that can secure the user's safety and improve the extinguishing capacity by securing and spreading the range of extinguishing powder.

Figure 2 is a longitudinal cross-sectional view showing the overall configuration of the fire extinguisher of the present invention, Figure 6 shows a cross-sectional view showing an operating state of the present invention,

The present invention comprises a substitute gas (10) consisting of a tapered cylindrical shape to be accommodated in the digestive powder (A) therein and having a female threaded portion (11) for fastening to the bottom;

A mesh body 20 of a predetermined mesh that is fixedly installed on the upper inner circumferential surface of the surrogate gas 10 and that provides a function of uniformly crushing the particles when the extinguishing powder is sprayed;

The cover 30 is installed integrally fixed to the inner circumferential surface of the surrogate gas 10 in a state located outside the mesh 20 and protects the mesh 20 and the fire extinguishing powder A until the extinguishing powder is sprayed. ;

A small body 40 having a conical shape and having a fastening male thread part 41 to be detachably fastened to the female thread part 11 of the surrogate gas 10;

Gunpowder 50 is installed in a solid body of a predetermined form on the inner bottom of the small gas 40 to generate an explosive force which is the driving force of the extinguishing powder (A);

It is combined with the gunpowder 50 and to include a working strap 60 is applied to the friction agent 61 on the outer peripheral surface to ignite the gunpowder when pulled.

In the above, the material of the gas 40 is appropriate to apply a metal plate such as tin so that it can handle the explosive force of the gunpowder, and the substitute gas 10 for accommodating the fire extinguishing powder (A) is applied even if the tin or thick earth It's okay.

In addition, the large and small container body (10, 40) is to be configured as a whole conical shape in order to give directivity to the injection direction of the extinguishing powder and the explosive force of the gunpowder, the inclination angle is not particularly limited, but about 30 degrees is suitable Do.
