Gardening sprayer with pressure relief function

Abstract

The invention relates to the technical field of gardening, in particular to a gardening sprayer with a pressure relief function. The gardening sprayer comprises a connecting rod, a pressurizing cylinder, a water storage bottle and an end cover, wherein the end cover is mounted at the upper part of the water storage bottle; an adjusting sleeve is mounted at the other end of the connecting rod; theadjusting sleeve is detachably connected with the connecting rod, a piston head is installed at the end, away from the connecting rod, of the adjusting sleeve, air guide holes are formed in the middlepositions of the piston head and the adjusting sleeve, air outlet holes are symmetrically formed in the two sides of the end, away from the air inlet holes, of the adjusting sleeve, the two air outlet holes communicate with the air guide holes, and the outer side of the connecting rod is wrapped with the pressurizing cylinder. By arrangement of the adjusting sleeve, the pressure of the device isin a stable state all the time during use, the problem of cylinder explosion is avoided, and the device is novel in design concept and scientific in design, has huge economic benefits and wide marketprospects and is worthy of application and popularization.

Description

technical field [0001] The invention relates to the technical field of gardening, in particular to a gardening sprayer with pressure relief function. Background technique [0002] Sprayer is the abbreviation of spray equipment. A sprayer is a device that uses air suction to turn liquid medicine or other liquids into mist and sprays them evenly on other objects. It is composed of compressed air devices, thin tubes, nozzles, etc. In rural areas, sprayers It is an indispensable and important agricultural tool for the prevention and control of diseases and insect pests. Not only that, the sprayer also plays a great role in gardening. The quality of the sprayer indirectly affects the growth of vegetation. Therefore, the demand for a gardening sprayer with pressure relief function, growing day by day.

AI Technical Summary

Problems solved by technology

[0003] When the existing device is in use, residual pressure is prone to occur inside the water storage bottle, resulting in deformation of the water storage bottle and overflow of liquid inside the water storage bottle. There is a big problem of frying drums, the safety of use is low, and the service life is short; not only that, the existing device is prone to the problem of liquid residue during use. At this time, the residual liquid will erode the device and it is easy to appear during the spraying process. The nozzle and water pipe blockage unit problem, therefore, a gardening sprayer with pressure relief function is proposed to solve the above problems
