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 spraying assembly (100) comprises a nozzle assembly (110), a pressure switch (120), a water pump device (130) and a main pipe (141). The main pipe (141) is obliquely arranged relative to the horizontal plane, and the pressure switch (120) arranged adjacent to the first end (1411) of the main pipe (141) is used for communicating a liquid inlet flow channel (111) with an exhaust flow channel (113)to exhaust gas in the spraying assembly (110). The invention further relates to a spraying system, a moving device and a spraying method.

Description

technical field [0001] The present application relates to the technical field of pump components and equipment, in particular to a spraying component, a spraying system, a mobile device and a spraying method. Background technique [0002] With the continuous improvement of environmental protection requirements, people have higher and higher requirements for anti-leakage of spraying systems when spraying is stopped. Due to the effect of gravity, when the existing spraying system stops spraying, the spray head usually has a problem of liquid dripping, that is, there is a problem of dripping, which causes the waste of liquid medicine and pollutes the environment. In order to solve the problem of dripping from the nozzle after the spraying is stopped, a normally closed pressure switch, namely a pressure relief valve, is usually installed on the nozzle. When the outlet pressure of the spraying system is greater than the pressure threshold, the spraying system will start spraying....
