A ball valve type discharge valve 16a is provided on the forced discharge hose 16 so as to be able to forcibly discharge the extinguishing liquid in the tank unit 10 when necessary.

2 and 3, the foam part 30 may be composed of a nozzle 31 and a body 32.

One end of the nozzle is connected to the other end of the fire hose (15). The nozzle 31 may have a first passage 31a communicating with the fire hose 15 therein. Therefore, the digestive fluid supplied through the digestive hose 15 is delivered to the first flow path 31a. In this case, a first mesh net 91 may be provided at one end of the first flow passage 31a. The first mesh net 91 may be a mesh of size 30mesh. The digestive fluid flowing into the first flow passage 31a through the first mesh net 91 is formed due to friction when passing through the first mesh net 91.

One end of the body 32 may be connected to the nozzle 31, and the other end thereof may be formed such that the injection unit 40 is connected to one end. A second flow path 32a may be formed in the body 32. The inner diameter of the second channel 32a may be larger than the inner diameter of the first channel 31a. The second flow path 32a may be formed such that an inner circumferential surface is fitted to the outer circumferential surface of the other end of the nozzle 31 so as to communicate with the first flow path 31a. Therefore, the extinguishing liquid flowing through the first channel 31a is dispersed as it passes through the expanded inner diameter of the second channel 32a.

In this case, a second mesh net 92 may be provided at the other end of the second flow passage 32a. The second mesh net 92 may be a mesh of 30 mesh size. The digestive fluid discharged from the second flow path 32a through the second mesh net 92 is formed due to friction when passing through the second mesh net 92.

Although the extinguishing fluid passing through the foam part 30 is formed by the above configuration, the foaming means 50 may be provided in the portable foam fire extinguishing device of the present invention to further increase the foaming effect.

The forming means 50 includes a forming air space 51, a forming air hole 52, a forming air hose 53, and a forming air injection unit 54.

The forming air space 51 may be formed in the body 32. The forming air space 51 may be formed to surround the outer circumference of the other end of the nozzle 31, and may be formed to be spaced apart from the second flow path 32a.

The forming air hole 52 may be formed through the circumferential surface of the body 32 so that the outside of the forming air space 51 and the body 32 communicate with each other.

The forming air hose 53 may be formed such that one end is connected to the air discharge part of the tank part 10 and the other end is connected to the forming air hole 52. Therefore, the compressed air in the tank unit 10 is supplied to the forming air space 51. A check valve CV may be provided on the forming air hose 53 to prevent backflow of compressed air.

The forming air injection unit 54 may be formed to communicate the forming air space 51 with the first flow passage 31a. Therefore, the compressed air contained in the forming air space 51 is discharged to the first flow path 31a through the forming air injection unit 54, and the extinguishing liquid flowing through the first flow path 31a is compressed air. It forms when it collides with and converts into a form digest.

Referring to FIG. 4, the forming air injection unit 54 will be described in detail. The forming air injection unit 54 may be formed at the other end surface of the nozzle 31. The forming air injection unit 54 may be formed in a plurality radially around the first flow path (31a). The forming air injection part 54 may be formed in a groove shape. The reason why the forming air injection part 54 is formed in a groove shape on the other end surface of the nozzle 31 is that the first embodiment is formed when the forming air injection part 54 penetrates through the circumferential surface of the nozzle 31. This is to prevent the pressure collision of the extinguishing liquid and the foam air flowing through the flow path (31a) can occur. In addition, the forming air injection unit 54 is formed at the point where the first passage 31a and the second passage 32a come into contact with each other, and the inner diameter of the second passage 32a is larger than the inner diameter of the first passage 31a. Therefore, when the flow path is extended, the digestive fluid and the forming air are brought into contact with each other, thereby minimizing pressure collision and maximizing the forming effect.

Therefore, the forming air injection unit 54 can be said to be the core configuration of the present invention.

The injection part 40 may include an injection hose 41, a hose reel 42, and an injection gun 43.

One end of the injection hose 41 may be connected to the other end of the foam part 30 so as to communicate with the second flow path 32a, and the other end thereof may be connected to one end of the injection gun 43. The hose reel 42 is provided on the spray hose 41 so as to be able to wind the spray hose 41, so that the length of the spray hose 41 may be increased while minimizing space. The injection gun 43 has an injection passage 43a and 43b formed therein, and one end thereof may be connected to the other end of the injection hose 41 so that the injection passage communicates with the injection hose 41. One end of the injection gun 43 is provided with a ball valve type injection valve 44 is configured to control the injection of the foam fire extinguishing liquid on the injection gun 43. In addition, one end of the spray gun 43 is provided with a third mesh network 93 may be configured to form the foam fire extinguishing once more. The injection passages 43a and 43b may be composed of an acceleration passage 43a and a diffusion passage 43b. The speed increase passage 43a decreases the inner diameter toward the other end to increase the flow rate of the foam digestion liquid flowing through the speed increase passage 43a, and the diffusion flow path 43b increases the inner diameter toward the other end. The diffusion of the foamed digestion liquid flowing through the diffusion passage 43b is facilitated. The effect is to evolve objects quickly and extensively.

The technical idea should not be construed as being limited to the above-described embodiment of the present invention. Various modifications may be made at the level of those skilled in the art without departing from the spirit of the invention as claimed in the claims. Therefore, such improvements and modifications fall within the protection scope of the present invention, as will be apparent to those skilled in the art.
