Knapsack sprayer utilizing an inflator to intermittently and uniformly emit cold air for sweat removal

Abstract

The invention discloses a knapsack sprayer utilizing an inflator to intermittently and uniformly emit cold air for sweat removal. The knapsack sprayer structurally comprises an atomization head, a telescopic rod, heat dissipation gratings, an atomizer body, a water pipe, a base, a sweat removing device and double shoulder straps; and one side of the atomizer body is provided with the heat dissipation gratings which are longitudinally arranged. Compared with the prior art, the knapsack sprayer has the beneficial effects that on the premise that air circulates, improvement is performed on the basis of the prior art, and convex portions of circular bulges and elliptical bulges are utilized to perform pipe arrangement design, so that the positions of the circular bulges and the elliptical bulges correspond to air outlet heads; by utilizing the inflator to perform intermittent inflation, air which is guided out provides cold air to the back of an operator, so that heat dissipation and sweatremoval of the back can be facilitated, and the back of the operator can be effectively prevented from being wetted through by excessive sweats; and the air can be uniformly guided out, so that the back can be uniformly cooled, sweat removal is more facilitated, the phenomenon of heatstroke of the operator can be avoided, and the sweats can be effectively prevented from falling into the air outlet heads at the same time.

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
