Description

Technical Field

[0001] The utility model relates to the field of medical spraying, in particular to a backpack sprayer. Background Art

[0002] A sprayer is a device that uses air suction to turn medicine or other liquids into mist and sprays them evenly onto other objects. The most widely used is a backpack sprayer, which is used to spray medicine to disinfect roads and ditches. Existing backpack sprayers include a cylinder for storing medicine liquid, a high-pressure gas cylinder for providing high-pressure gas to the medicine liquid in the cylinder, a manual pressure rod for providing high-pressure gas to the high-pressure gas cylinder, and a nozzle for spraying the medicine liquid. When working, the manual pressure rod is repeatedly lifted and pressed by hand to compress air in the atmosphere into the high-pressure gas cylinder, so that the gas in the high-pressure gas cylinder maintains a certain pressure. The gas in the high-pressure gas cylinder acts on the medicine liquid in the cylinder, and the medicine liquid is sprayed out from the spray hole of the nozzle in a mist-like state at high speed, thereby achieving the purpose of spraying.

[0003] However, this backpack sprayer requires manual operation, and fatigue is greatly increased after working for a long time. There is a backpack spray box that can solve the above technical problems, which includes a medicine box, a fan, a liquid outlet pipe and a cable.
