Description

Technical Field

[0001] The utility model relates to the technical field of nozzles, in particular to a self-explosive high-pressure fine water mist nozzle device. Background Art

[0002] Existing self-explosive fine water mist nozzle devices usually use glass shell explosion low-pressure spraying or electromagnetic energization spraying. The water mist droplets sprayed are too large to form a fog cover to completely isolate the burning object from the air and prevent combustion. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a self-explosive high-pressure fine water mist nozzle device, which can better form a fog cover, quickly and effectively extinguish the fire source, and can also work normally without power supply. In order to achieve the above purpose and other advantages according to the present invention, a self-explosive high-pressure fine water mist nozzle device is provided, including:

[0004] A shell, wherein an upper cover is fixedly connected to the upper end of the shell, a lower cover is threadedly connected to the lower end of the shell, and a clearance interval is provided inside the shell, an air bag is arranged in the clearance interval, and the air bag is threadedly connected to the lower cover;

[0005] A valve core is placed in the upper cover, and the valve core is in contact with the air bag;

[0006] A second clearance interval is provided on the lower cover, and a push component is placed in the second clearance interval, and the push component is used to deflate the airbag;

[0007] A plurality of first water channels are provided in the shell, a plurality of second water channels are provided in the lower cover, the first water channels are connected with the second water channels, and nozzles are fixedly connected to the lower cover at the second water channels.

[0008] Preferably, the pushing assembly includes a spring placed in the second yielding interval and a push rod placed in the spring, and the push rod puts the spring in a compressed state.

[0009] Preferably, one end of the lower cover is fixedly connected to a base, the base is fixedly connected to an air explosion chamber, one end of the push rod is located in the air explosion chamber, and the other end of the push rod is close to the airbag.

[0010] Preferably, a water hole is provided inside the upper cover, the water hole is connected to the make way interval, and the make way interval is connected to the plurality of first water channels.

[0011] Compared with the prior art, the utility model has the following beneficial effects: through the explosion of the gas explosion chamber, the push rod moves toward the airbag driven by the spring, and the airbag is gradually exhausted under the force of the push rod. At this time, the valve core gradually moves toward the airbag, so that the airbag is completely in the shell, and the high-pressure water is applied to the nozzle through the upper cover, and the nozzle sprays water to form a fog cover. Compared with the traditional low-pressure fine water mist nozzle or the electrified low-pressure water spray, the self-explosive high-pressure fine water mist nozzle sprays out better droplets, better forms a fog cover, quickly and effectively extinguishes the fire source, and can also work normally without power supply.
