When the jet head is described in detail with reference to FIGS. 8 and 9 , the diameter D3 of the water jetting area P1 is larger than the diameter D2 of the jetting head 120 , and the diameter of the water jetting area or the water pressure water jetting area is larger than the diameter D2 of the jetting head 120 . (D3) is changed according to the distance between the injection head 120 and the flame. In general, as the distance between the spray head and the flame increases, the diameter of the water spray area increases. When the distance between the jet head 120 and the flame of the present invention is 60 cm, the size of the water jet region P1 has a diameter of 0.8M to 1.3M, and the distance between the flame and the jet head is adjusted according to the shape of the flame. Thus, the size of the water spraying area can be adjusted. The tap water or water pressure water uniformly sprayed to the water spray area through the spray head 120 is sprayed to have a predetermined area in the shape of a water umbrella (water film). The flame in the water umbrella (water film) area lacks oxygen to sustain a fire state, and a cooling effect by the latent heat of tap water or water pressure water occurs, so that suffocation and cooling fire extinguishing can be effectively performed. In addition, since the flame cannot escape the water spray area P1 in the shape of a water umbrella (water film), it is possible to prevent the spread of fire. In particular, when a fire occurs in general furniture and bedding, the effect of preventing the spread of flame and the fire extinguishing function are excellent. Furthermore, according to the structure of the spray head 120 of the present invention, tap water or water pressure water can be sprayed simultaneously over a wide area, so that when a fire occurs in the lower floor of the user's house, the user By spraying tap water or water pressure water on the balcony glass of one's own house, it not only blocks the flame from spreading to the inside, but also allows the water or water pressure water to be sprayed to the lower part to prevent the fire from spreading in the house. can be effectively prevented. In the event of a fire on the lower floor, the temperature of the ceiling of one's own house does not rise to 79 °C, so water cannot be discharged from the sprinkler head installed on the ceiling, and the external flame breaks the window of the veranda and enters the house and the fire spreads. Therefore, by using the fire extinguishing pressure box of the present invention, it is possible to wet the combustible material in the house and continuously spray water on the glass installed on the veranda, etc. to prevent the spread of fire.

Comparing the function and price of the fire extinguishing pressurized box of the present invention described above with a conventional fire extinguisher, a conventional fire extinguisher is typically available for one-time use. As long as tap water or water pressure water is continuously supplied through the water pipe, the fire extinguishing pressurized box can be used until the fire is extinguished. In general, when 25L of tap water or water pressure water is sprayed per minute, the amount of 100L tap water or water pressure water is sprayed for about 3 to 5 minutes. Perfect suppression is possible.
