[0002] A water mist nozzle, also known as an atomizing nozzle or a mist nozzle, is a nozzle device commonly used in agriculture and industry. Its working principle is based on the liquid being ejected through small holes or slits under the action of high pressure inside the nozzle, thus forming an atomization effect. Specifically, a high-pressure pump pushes the liquid into the nozzle and ejects the liquid through the small holes or slits in the nozzle.

[0003] After searching the Chinese patent "A high-pressure fine water mist open water spray device", the publication number is "CN214975180U". This patent solves the problem that the existing sprinkler still drips after the fire is extinguished by adding an anti-drip device. The utility model has a simple structure, convenient maintenance and replacement, and easy use. However, the device is prone to incomplete closure during use, and it is not convenient to effectively seal the fine water mist sprinkler, which makes the fine water mist sprinkler prone to dripping.

[0004] Therefore, a drip-proof water mist nozzle is proposed to solve the above problems. Utility Model Content

[0015] 1. By setting a sealing mechanism, when the fine water mist nozzle drips, the first sealing ball in the fine water mist nozzle is clamped on the mounting block, and cooperates with the groove on the mounting block to prevent water leakage. The first sealing ball cooperates with the compression spring to prevent water leakage. When in use, the water flow squeezes the first sealing ball and the compression spring into the fixed cylinder through the impact force, and the second sealing ball in the water guide groove can close the water guide groove through its own gravity to prevent water leakage. The motor controls the rotating rod to drive the ball valve to rotate, and controls the water flow in the fine water mist nozzle, which can prevent the fine water mist nozzle from dripping and improve the sealing of the fine water mist nozzle.
