[0031] Reference Figure 1-4 The utility model provides an embodiment: a fine water mist nozzle, including a main body 1, a water pipe 2 is arranged inside the main body 1 near the upper end, which is convenient for conveying water to the device, the main body 1 includes a shell 101, a slide groove 102 is opened inside the shell 101, and a connecting ring 103 is slidably arranged inside the slide groove 102 near the upper end.

[0032] An atomizing head 104 is fixedly arranged inside the connecting ring 103, which belongs to the existing structure. The principle is that the atomizing effect can be achieved through multiple small holes to disperse the liquid into tiny droplets. The first connecting rod 109 is rotatably arranged on both sides of the lower end of the atomizing head 104. The dustproof plates 110 are rotatably arranged on both sides of the lower end of the shell 101 to prevent foreign matter from entering the interior of the device. A stopper 107 is fixedly arranged on the upper end of the atomizing head 104. Multiple water inlets 106 are opened on the upper end of the atomizing head 104. The water inlet 106 is arranged through. It is convenient for water to enter the atomizing head 104 for atomization. When using this device, the block 107 is squeezed by the water flow, so that the block 107 drives the atomizing head 104 to move downward, and then the dustproof plate 110 is driven to open by the first connecting rod 109. At the same time, the water flows into the atomizing head 104 through the water inlet 106, and the water can be atomized and sprayed out for fire extinguishing. When the use is over, the water flow is stopped, and the atomizing head 104 is reset, so that the atomizing head 104 drives the dustproof plate 110 to close to prevent foreign matter from entering the interior of the nozzle.

[0033] The two first connecting rods 109 are respectively arranged inside the two movable grooves 111, and the second springs 112 are fixedly connected between the two movable grooves 111 and the two first connecting rods 109. When the device is used, the second connecting rod 115 is used to conveniently drive the dustproof plate 110 to move. At the same time, the second connecting rod 115 can be reset by the second spring 112, which facilitates the atomizing head 104 to drive the dustproof plate 110 to close through the first connecting rod 109 and the second spring 112 to prevent foreign matter from entering the interior of the nozzle. A baffle 108 is fixedly provided at the upper end of the shell 101, and a shell 117 is provided on the outer surface of the shell 101. The strong material is used to protect the device. When the device is used, the baffle 108 is separated by the block 107 to facilitate the water flow into the atomizer head 104. A first spring 105 is fixedly connected between the slide groove 102 and the connecting ring 103 near the atomizer head 104. When the device is used, the atomizer head 104 is easily reset by the first spring 105.

[0034] A rotating rod 114 is fixedly provided at the lower end of the shell 101, and two second connecting rods 115 are rotatably provided on both sides of the rod body of the rotating rod 114. Brushes 116 are rotatably provided on the upper ends of the two second connecting rods 115. The two brushes 116 are slidably provided on both sides of the lower end of the atomizing head 104. When the device is used, the atomizing head 104 moves downward, so that the brush 116 is driven by the second connecting rod 115 to move, so as to facilitate the cleaning of the atomizing head 104. A placement groove 113 is provided at the lower end of the atomizing head 104. When the atomizing head 104 moves downward, the rotating rod 114 can be placed in the placement groove 113. A fine water mist fire extinguishing device includes a fine water mist nozzle. When the device is used, a water source can be provided for the atomizing head 104, so as to facilitate fire extinguishing through the atomizing head 104.

[0035] Working principle: When using this device, first, the block 107 is squeezed by the water flow, and then the block 107 is separated from the baffle 108, so that the block 107 drives the atomizing head 104 to move downward, and then the dustproof plate 110 is driven to open by the first connecting rod 109. At the same time, the water flow first enters the inside of the atomizing head 104 through the water inlet 106, and the water flow can be atomized and sprayed out for fire extinguishing. Moreover, when the atomizing head 104 moves, the second connecting rod 115 is then squeezed, so that the brush 116 moves on the atomizing head 104 to clean the atomizing head 104. Finally, when the use is finished, the water flow is stopped first, and then the atomizing head 104 is reset by the first spring 105, and then the atomizing head 104 drives the dustproof plate 110 to be closed by the first connecting rod 109 and the second spring 112.
