[0046] To better understand this utility model, the following is combined with... Figure 1 - Figure 4 The working principle of the technical solution of this utility model will be described in detail below:

[0047] In the early stages of a fire, when using this water mist fire extinguishing device, rotating the cover plate 130 allows it to be removed from the opening of the cavity 111, connecting one end of the water injection pipe to the water source, placing the other end of the water injection pipe into the slot 112, and positioning the other end of the water inlet pipe 140 on the guide plate 150. At this point, the other end of the water inlet pipe 140 is connected to the water inlet cavity 1111. The cover plate 130 is then placed back over the opening of the water inlet cavity 1111. The cover plate 130 limits the water injection pipe, preventing it from easily detaching from the housing 110 during water injection. Water is then injected through the water injection pipe into the cavity 1111. Water is filled into the water inlet chamber 1111, and the water in the water inlet chamber 1111 enters the water storage chamber 1112 through the water inlet 121. Holding the water spray gun and aiming it at the fire source, the switch button on the spray gun is pressed, and the drive pump is turned on. This allows the water in the water storage chamber 1112 to be drawn out and enter the water spray gun through the water outlet pipe. The water spray gun sprays water mist to extinguish the fire. Continuously filling the water storage chamber 1112 with water allows the water spray gun to continuously spray water mist, thereby extinguishing larger fire sources in a timely and rapid manner. This water mist fire extinguishing device uses water for fire extinguishing, which is more economical and can replenish water in a timely manner to ensure the continuity of fire extinguishing. It can extinguish larger fire sources in a timely and rapid manner.

[0048] The water mist fire extinguishing device provided by this utility model has the following beneficial effects:

[0049] (1) The upper end of the water inlet pipe 140 is connected to the water inlet 121, and the lower end of the water inlet pipe 140 is close to the bottom of the water storage chamber 1112. The water inlet pipe 140 has an upper section 141 and a lower section 142 that are connected to each other. The upper section 141 is a conical structure with a pipe diameter that gradually decreases from top to bottom, and the lower section 142 is a columnar structure. This can prevent the water mist fire extinguishing device from tipping over and leaking water, and improve the effect of preventing tipping over and leaking water.

[0050] (2) During the process of water in the water inlet 1111 entering the water storage chamber 1112 through the water inlet 121, the sponge block and the filter screen 310 can filter impurities in the water. The dual filtration effect of the sponge block and the filter screen 310 can improve the filtration effect of impurities in the water.

[0051] (3) This water mist fire extinguishing device uses water for fire extinguishing, which is more economical and can replenish water in a timely manner to ensure the continuity of fire extinguishing. It can extinguish larger fire sources in a timely and rapid manner.
