Description

Shoulder-carried sprayer

Technical Field

The utility model relates to a sprayer specifically is an adopt lithium cell as power drive's shoulder back of body formula sprayer.

Background

The shoulder-carried sprayer is mainly a sprayer which is carried on the back of a human body by adopting a knapsack structure to perform the work of spraying, sterilizing and the like, and has the advantages of flexible and convenient use, lower manufacturing cost and the like. The shoulder-carried type sprayers can be divided into electric sprayers and manual sprayers according to different driving modes. The manual sprayer has the biggest defects that the labor intensity of operators is high, on one hand, the weights of a loading device and liquid medicine are needed, on the other hand, a pressure pump needs to be driven manually continuously, the defects of low working efficiency, low speed, limited liquid medicine spraying pressure, short spraying distance and the like exist frequently, and the manual sprayer is easy to cause pollution of pesticide to human bodies and harmful to human health. The electric sprayer can automatically supply liquid and electrically spray uniformly, so that the labor intensity of operators is reduced, but a battery pack serving as a power supply usually adopts a lead-acid storage battery and is directly sealed at the bottom of a water tank for storing liquid medicine, the whole sprayer can only be integrally moved and charged due to the fact that the battery pack cannot be disassembled, and particularly after the water tank is filled with the liquid medicine, the charging process is very troublesome and laborious, and potential safety hazards also exist; meanwhile, the lead-acid storage battery which cannot be disassembled is inconvenient to maintain and replace, the service life is short, and the lead-acid storage battery is easy to cause environmental pollution after being damaged and abandoned.

Disclosure of Invention

The utility model aims to solve the technical problem that overcome prior art's defect and provide an adopt the lithium cell of removable installation as the shoulder back of the body formula atomizer of battery package.

The technical problem of the utility model is realized through following technical scheme:

a shoulder-back sprayer comprises a back rest assembly, a water tank arranged on the back rest assembly, a battery pack and an electric water pump which are arranged in the water tank and are in conductive connection, and a spray rod arranged outside the water tank; the water inlet of the electric water pump is communicated with the water tank, the water outlet of the electric water pump is communicated with the spray rod, the battery pack is a lithium battery pack, the battery pack is arranged in a battery box at the bottom of the water tank, and a door cover for the battery pack to be put in or taken out is arranged on the battery box.

The battery box is composed of an upper shell integrally formed at the bottom of the water tank and a lower shell detachably buckled at the bottom of the upper shell, and the battery pack and the electric water pump are both arranged between the upper shell and the lower shell; the outer surfaces of the upper shell and the lower shell are provided with door openings for opening or closing the door covers.
