A knapsack sprayer that uses an air pump to distribute cold air intermittently and evenly to remove sweat

Abstract

The invention discloses a knapsack sprayer which utilizes an air pump to intermittently and evenly emit cold air to remove sweat. There are longitudinally arranged heat dissipation grills on one side of it. Compared with the prior art, the beneficial effect of the present invention is that: on the premise that the air circulates, the prior art is improved, and the use of circular protrusions , The protruding part of the ellipse is designed with a step tube, so that each circular and elliptical protruding position corresponds to an air outlet head, and the pump is used to inflate intermittently, and the exported gas provides cold air for the back of the operator. It is convenient for heat dissipation and deperspiration of the back, effectively preventing the back of the operator from getting drenched due to excessive sweating, and the gas can be evenly exported, so as to ensure that the back can be evenly cooled, which is more conducive to deperspiration and avoid heatstroke of the operator , At the same time, it can also effectively prevent sweat from falling into the outlet head.

Description

technical field [0001] The invention relates to the technical field of agricultural equipment, in particular to a knapsack sprayer which utilizes an air pump to distribute cold air intermittently and evenly to remove sweat. Background technique [0002] In rural areas, sprayers are an indispensable agricultural tool for preventing and controlling pests. Sprayers can be divided into portable sprayers, knapsack sprayers and hand-push sprayers. The technology is not perfect enough, and has the following defects to be improved: [0003] When using the knapsack sprayer, it is carried on the shoulder through the strap, and the liquid storage tank is against the back. Although there are round and oval protrusions, the distance between the back and the back pad is very small. For workers who are prone to sweating , the back is very easy to get wet, and the wet clothes are easy to stick to the back pad, and the wind in summer is so slight that it can't play the role of air circulati...

Problems solved by technology

[0003] When using the knapsack sprayer, it is carried on the shoulder through the strap, and the liquid storage tank is against the back. Although there are round and oval protrusions, the distance between the back and the back pad is very small. For workers who are prone to sweating , the back is very easy to get wet, and the wet clothes are easy to stick to the back pad, and the wind in summer is so slight that it can't play the role of air circulation at all, so the speed of sweating is far slower than the speed of sweating , most likely due to heat stroke
