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.
