Description

Technical Field

[0001] The present application relates to the field of universal joints, and in particular to a dry fog universal joint. Background Art

[0002] Compressed air enters the air inlet channel of the dry mist nozzle through the air inlet pipe. When the compressed air passes through the cavity inside the dry mist nozzle, it compresses and sucks in the liquid, causing the liquid in the water inlet channel to enter the cavity. The compressed air passes through the nozzle head at a supersonic speed. When the gas speed exceeds the speed of sound, sonic boom and ultrasonic vibration are generated. The liquid is broken into tiny particles when passing through the nozzle. After entering the sonic boom area, it is further vibrated into droplets with a diameter of 1-10μm, and dry mist is sprayed out from the nozzle head.

[0003] In order to expand the spray range of the existing dry mist nozzle, the dry mist nozzle is installed through a universal joint. However, the existing universal joint and the delivery pipe are fixedly connected. Since the universal joint is prone to wear, it needs to be maintained regularly. The fixed connection is inconvenient to disassemble. Utility Model Content
