The spraying assembly 2 includes a connecting pipe 21 and a spraying hose 22, wherein the connecting pipe 21 can be a plastic pipe or a metal pipe, and is connected to the inner cavity of the shell 1, and can transport the fire extinguishing agent in the inner cavity, and the connecting pipe 21 can also rotate around the axis of the connecting pipe 21 itself relative to the shell 1, so as to increase the range of spraying the fire extinguishing agent. One end of the spraying hose 22 is connected to the connecting pipe 21, and the other end extends in a direction away from the connecting pipe 21. In order to increase the spraying range of the fire extinguishing agent, a plurality of spraying hoses 22 are provided, and are distributed along the circumference of the connecting pipe 21.

[0030] When a fire occurs, the staff can open the fire extinguishing device to allow the fire extinguishing agent in the inner cavity of the shell 1 to enter the connecting pipe 21, so that the fire extinguishing agent can be transferred to the spray hose 22 in the connecting pipe 21. While the fire extinguishing agent is being transferred, the connecting pipe 21 also rotates relative to the shell 1, and the spray hose 22 on the connecting pipe 21 also rotates synchronously with the connecting pipe 21. Through the action of centrifugal force, the fire extinguishing agent sprayed from the spray hose 22 can be sprayed a longer distance, thereby increasing the range of the spray hose 22 spraying the fire extinguishing agent and improving the efficiency of fire extinguishing.

[0031] The fire extinguishing device of the present disclosure is provided with a connecting pipe 21 that can rotate relative to the shell 1, and a plurality of spray hoses 22 are provided on the connecting pipe 21.
