Spray nozzle of sprayer

Abstract

A spray nozzle of a sprayer comprises a main body of the spray nozzle, a head cap, a water distribution sleeve, a wrench, a big ring and a one-way liquid inlet mechanism, wherein one end of the water distribution sleeve is embedded in the head of the main body, and the other end butts against the head cap; a piston body is arranged in a cylinder body of the main body and inserted at the inner end of a piston body seat; one end of the piston body seat exposed outside the cylinder body is in butting fit with a top plate on the wrench; the wrench is articulated outside the main body; one end of a spring is embedded in the main body and the other end thereof is arranged at the inner end of the piston body; and a check valve is arranged in a liquid channel close to a liquid outlet part. The spray nozzle of the sprayer is characterized in that the check valve is made of soft plastic, one end of the check valve is inserted in the water distribution sleeve, and the other end is arranged in the liquid channel, and the check valve is sealed with the liquid channel in a matching way through a valve on the check valve. As the check valve is made of high soft plastic, the spray nozzle of the sprayer has simple structure, convenient manufacturing and low cost.

Description

technical field [0001] The invention relates to a nozzle of a nebulizer. Background technique [0002] At present, sprayers are widely used in agriculture, forestry, animal husbandry and other occasions to kill pests. With the continuous improvement of people's living standards, various beauty, makeup, washing and other industries also need to use sprayers. For this reason, there are many technologies Personnel made improvements to the sprayer. [0003] For example, the patent No. 200720111607.2 is a nozzle of a sprayer, which includes the main body of the nozzle, the casing, the head cap, a wrench, a large ring, and a suction pipe. The inner end of the body seat, the end of the piston body seat exposed outside the cylinder body is in conflict with the top plate on the wrench, the wrench is hingedly connected to the outside of the main body, and a spring is supported between the inner end of the piston body and the cylinder body, which is characterized in that The cylinder...

Problems solved by technology

[0003] For example, the patent No. 200720111607.2 is a nozzle of a sprayer, which includes the main body of the nozzle, the casing, the head cap, a wrench, a large ring, and a suction pipe. The inner end of the body seat, the end of the piston body seat exposed outside the cylinder body is in conflict with the top plate on the wrench, the wrench is hingedly connected to the outside of the main body, and a spring is supported between the inner end of the piston body and the cylinder body, which is characterized in that The cylinder body is arranged horizontally on the main body close to the one-way valve, and the air outlet of the cylinder body is facing the upper part of the sealing bead of the one-way valve, so that the gas in the cylinder body can affect the action of the sealing bead more quickly, so as to achieve the quick switch of the one-way valve effect, making the action of the sprayer more sensitive and reliable. The defect is that the one-way valve includes at least a sealing bead and its seat body, which makes its structure complex, difficult in process, and high in cost.
