Abstract

The invention discloses a negative-pressure type sprayer for a fruit tree atomizer. The sprayer comprises a sprayer body and a sprayer cap. A high-pressure runner is arranged in the middle of the sprayer body. The sprayer body is in threaded connection with the sprayer cap. A nozzle is arranged on the left side of the sprayer body. A spraying hole with the taper is formed in the nozzle. One side of the spraying hole is communicated with the high-pressure runner, and a discharging hole is formed in the other side of the spraying hole. An air hole is formed in the spraying hole. The spraying hole is communicated with the discharging hole and the air hole. The scheme has the beneficial effects that the principle of a vacuum generator is utilized, high-speed compressed air is introduced in the liquid pesticide spraying hole, and a certain vacuum degree is generated at the spraying hole through the high-speed compressed air; by means of the structure, on one hand, liquid pesticide can be scattered, liquid pesticide can be sprayed out of the discharging hole easily, and the liquid pesticide is prevented from blocking the discharging hole; and on the other hand, the liquid pesticide can be sprayed to a fruit tree in a high-speed and even vaporific sector manner through the scheme, and accordingly the liquid pesticide can be evenly and effectively sprayed to the fruit tree.

Description

technical field [0001] The invention relates to a nozzle of a sprayer, in particular to a negative pressure nozzle for a sprayer for fruit trees. Background technique [0002] At present, fruit trees planted in different regions of my country are often harmed by various pests during the growth process, which has a great impact on the normal growth of fruit trees. For this situation, two methods are usually used: artificial physical control and chemical drug control. Artificial physical control mainly includes collecting pupae, tying grass handles, trapping and killing with lights, catching adults, and killing mature larvae. This method is cumbersome and the effect is not good. , Chemical control is generally sprayed on the fruit trees with a sprayer. [0003] The nozzle hole is an important part of the sprayer. The size of the nozzle hole is generally small. Therefore, after a period of use of the traditional sprayer, the residual liquid medicine is easy to cause the blocka...
