[0043] It should be noted that

[0044] (1) This electrostatic sprayer is composed of a 200L-1500L (optional) medicine barrel, an air compressor, an electrostatic generator, an electrostatic nozzle, a main frame, an engine (optional) and other components.

[0045] (2) The sprayer uses an air compressor to drive the front-stage electrostatic two-fluid nozzle, thereby breaking up the water droplets and spraying them out of the nozzle.

[0046] (3) When the droplets are sprayed out of the nozzle, the electrostatic nozzle charges the droplets with high voltage and breaks up the droplets again. Thus, the droplets are sprayed out with ionic charge.

[0047] (4) The high-speed turbine blower generates a wind pressure of approximately 37 kp, which disperses the droplets and can deliver droplets with a median diameter of 80 μm to a height of approximately 6 meters. The spray nozzles on both sides spray a 12-meter radius within the greenhouse. The sprayer produces approximately 200 liters of mist per hour and can cover approximately 15 mu of land per hour. This saves approximately twice as much liquid as conventional sprayers.

[0048] (5) Uniform load droplets. Electrostatic charge can effectively reduce the size of droplets and improve the uniformity of droplets.

[0049] (6) The same charge, large diffusion area, and good sedimentation of distributed droplets. The droplets formed by static electricity have the same charge. They repel each other in space and do not condense with each other, so the coverage of the target is very uniform. The droplets float in the air for a long time and spread over a wide area. The adsorption and disinfection effect on bacteria and dust in the air is twice that of ordinary sprayers. Under the premise of the same amount of medicine, the amount of medicine applied by the electrostatic sprayer is about half that of the ordinary sprayer.

[0050] (7) Long lasting effect. Since the charged droplets have a strong adsorption capacity on the target and are evenly distributed, the application efficiency is high and the effect lasts longer.

[0051] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are exemplary and are not to be construed as limitations on the present invention. A person skilled in the art may change, modify, replace and modify the above embodiments within the scope of the present invention.
