Problems solved by technology

[0003] However, for pluggable water tanks, that is, water tanks that can be detached from mobile platforms such as drones, each time the water tank is plugged and unplugged, it is easy for air to enter the pipes of the sprinkler system.
When there is air in the pipeline of the sprinkler system, especially in the pump chamber, the outlet pressure of the sprinkler system is difficult to reach the above pressure threshold, so that the pressure relief valve cannot be pushed back to exhaust
At this time, it is necessary to manually open the pressure relief valve on each nozzle to discharge the gas in the spraying system, which is time-consuming and laborious, and increases labor costs

Abstract

A sprinkler assembly (100), comprising a spray head assembly (110), a pressure switch (120), a water pump device (130) and a main pipe (141), the main pipe (141) is inclined relative to the horizontal plane, and the first pipe adjacent to the main pipe (141) The pressure switch (120) provided at the end (1411) is used to connect the liquid inlet channel (111) and the exhaust channel (113), so as to discharge the gas in the spray assembly (110). It also relates to a spraying system, a mobile device and a spraying method.

Description

technical field [0001] The present application relates to the technical field of pump assembly equipment, and in particular, to a spraying assembly, a spraying system, a moving device and a spraying method. Background technique [0002] With the continuous improvement of environmental protection requirements, people have higher and higher requirements for leakage prevention of spraying systems when spraying is stopped. Due to the action of gravity, when the existing spraying system stops spraying, the spraying head usually has liquid dripping, that is, there is a leakage problem, which results in waste of the medicinal liquid and also causes pollution to the environment. In order to solve the problem of dripping from the nozzle after spraying is stopped, a normally closed pressure switch, namely a pressure relief valve, is usually set on the nozzle. When the outlet pressure of the spraying system is greater than the pressure threshold, the spraying system will perform the sp...
