SPRAY HEAD DEVICE, SPRAYING SYSTEM, MOVABLE PLATFORM AND SPRAYING OPERATION METHOD THEREFOR

WIPO Patent Application WO/2020/220215

A1

Provided are a spray head device, a spraying system, a movable platform and a spraying operation method therefor. The spray head device (100) comprises a first sub-spray head (110), a second sub-spray head (120) and a switch device (130), wherein the switch device (130) respectively communicates with a first water inlet nozzle and a second water inlet nozzle and controls liquid to be selectively sprayed by means of the first sub-spray head (110) or the second sub-spray head (120); and under conditions where there is the same hydraulic pressure of the liquid, spray parameters of the first sub-spray head (110) are different from spray parameters of the second sub-spray head (120), and the spray parameters comprise at least one of a spraying flow rate and a spraying width. By means of the switch device, liquid is controlled to be sprayed out of spray head devices with different spray parameters, the flow rate and the spraying width are changed during the process of spraying, such that the time for manually changing a nozzle is saved on, the spray efficiency is improved, droplet leakage is prevented, the safety is improved, and the user experience is improved.
