[0002] The electric sprayer is composed of a liquid storage barrel connected in sequence through a filter, a connecting head, a suction device (a small electric pump), a connecting pipe, a nozzle, and a nozzle. The suction device is a small electric pump, which is electrically connected to the battery through wires and switches. The battery box is installed at the bottom of the liquid storage barrel. The liquid storage barrel can be made into a groove with a sunken battery. The advantages of the electric sprayer are that the suction suction cylinder is eliminated, thereby effectively eliminating the disadvantages of pesticide external filtration that harms the operator, and it saves labor. The pressure of the electric pump is greater than that of the manual suction cylinder, which increases the spraying distance and range. The atomization effect is good, saving time, labor, and medicine.
