[0002] A fog cannon truck is a type of fire-fighting equipment, which includes small fog cannon trucks and large fog cannon trucks. Its main function is to atomize water into tiny water mist particles through high-pressure equipment. After these particles come into contact with dust in the air, they will aggregate into large particles, thereby reducing the particulate matter content in the air.

[0003] According to observations based on existing technologies, the spraying range of the fog cannon truck is limited during use, and manual rotation is required during the rotation process. Manual operation may affect the uniformity of the spraying range, and long-term operation will also increase the fatigue of the staff. The fog cannon truck needs to treat the water when spraying, and neutralize it by adding disinfectants or other agents. Generally, the water is treated first and then sprayed, which will reduce the efficiency of the spraying. Utility Model Content
