Household liquid medicine sprayer

Abstract

The invention relates to the technical field of sprayers, in particular to a household liquid medicine sprayer which comprises a body, and a water storage tank, a liquid medicine box, a quantitative unit and an atomization unit that are arranged in the body; the liquid medicine box is provided with a first concentration detector; the quantization unit comprises a controller, a second concentrationdetector and a liquid mixing box; the second concentration detector is arranged in the liquid mixing box, the water storage tank is connected with the liquid mixing tank through a water outlet valve,the liquid medicine box is connected with the liquid mixing box through a liquid medicine valve, the controller is electrically connected with the water outlet valve, the liquid medicine valve, the first concentration detector and the second concentration detector; the atomization unit comprises a piezoelectric ceramic piece, an anti-corrosion layer and a microporous filtering layer, the piezoelectric ceramic piece is electrically connected with the controller, the anti-corrosion layer and a micro-hole filtering layer are attached to the surface of the piezoelectric ceramic piece in sequence,the micro-hole filtering layer is provided with a plurality of first filtering holes, and the aperture of each first filtering hole ranges from 20 [mu]m to 60 [mu]m. According to the invention, the liquid medicine residue generated in the spraying process of plants can be reduced, and the service life of the atomization unit is prolonged.

Description

technical field [0001] The invention relates to the technical field of sprayers, in particular to a household liquid medicine sprayer. Background technique [0002] At present, the household pesticide sprayers on the market are all constant sprays (also known as high-capacity sprays), which use hydraulic atomization for spraying. The common pressure is 0.3-0.4MPa, and the spraying liquid volume is generally 450-1500L / hm 2 , The droplet diameter is between 150 and 1200 μm. The manual sprayers and compressed sprayers commonly used in our country all adopt the constant spray technology. The constant spray technology uses a large amount of chemical solution per unit area, and the utilization rate of pesticides is low. The chemical solution is easy to be lost and wasted, which increases the cost of prevention and control, and also causes serious pollution to the air, soil and home environment. [0003] At present, the sprayers on the market belong to mechanical atomization, wit...

Problems solved by technology

Constant spray technology applies a large amount of liquid medicine per unit area, and the utilization rate of pesticides is low. The liquid medicine is easy to be lost and wasted, which increases the cost of prevention and control, and also causes serious pollution to the air, soil and home environment.

[0003] At present, the sprayers on the market belong to mechanical atomization, with heavy structural design, cumbersome and complicated operation, large volume of atomizers, serious noise, pollution of the surrounding environment, low utilization rate of pesticides, not suitable for home gardening and small gardens, and in use When spraying, the concentration of the spraying liquid is determined at the time of purchase, but different plants have different requirements for the concentration of the liquid. If the concentration of the liquid is too high, the plants cannot fully absorb it, and the subsequent volatilization into the air will still pollute the indoor environment. environment, and the manual blending of the liquid medicine cannot accurately blend the liquid medicine with a suitable concentration

[0004] In addition, because the atomization unit of the nebulizer has been in contact with the liquid medicine for a long time, most of the liquid medicine is corrosive, which easily affects the service life of the atomization unit
