Electric sprayer nozzle

Abstract

The invention relates to an electric sprayer nozzle and belongs to the technical field of spraying devices. The electric sprayer nozzle is fixed to a water tank through a bayonet. The electric sprayer nozzle comprises a shell, an air pump, a battery and a master control plate. The air pump, the battery and the master control plate are fixed to the shell. A pressure sensor is arranged on the inner side of an air outlet of the air pump and connected to the bayonet through a hose. The battery is used for supplying electricity to the air pump, the master control plate and the pressure sensor. An air inlet of the air pump is communicated with the atmosphere. The air outlet of the air pump is arranged on the bayonet and connected with the water tank. The signal input end of the master control plate is connected with the output end of the pressure sensor. The control output end of the master control plate is connected with the control end of the air pump. A breathable and waterproof column plug is arranged at the end, located on the bayonet, of the hose. The portion, located on the water tank side, of the bayonet is covered with a breathable and waterproof membrane. According to the electric sprayer nozzle, due to the mode that the breathable and waterproof membrane and the breathable and waterproof column plug are arranged, water is prevented from entering the pressure sensor of the electric sprayer nozzle, and therefore the problem that the electric sprayer nozzle is out of order is solved.

Description

technical field [0001] The invention relates to an electric spray head, which belongs to the technical field of spray devices. Background technique [0002] Sprayer is the abbreviation of spray equipment. A sprayer is a device that uses air suction to turn medicine or other liquids into mist and sprays them evenly on other objects. It is composed of compressed air devices, thin tubes, nozzles, etc. [0003] Generally speaking, it is pressurized manually. The sprayer is a cylinder with a height of 80 cm and a diameter of about 25 cm. When spraying the medicine, put it on the ground to inflate it, and then carry it behind your back. When the air is exhausted and the mist surface of the liquid medicine becomes smaller, put it on the ground to inflate it, and then carry it on your back...and so on. It was labor-intensive and time-consuming, and several barrels of medicine could not be dispensed in half a day. [0004] Relatively speaking, although the electric sprayer has the...
