Patent attributes
The present invention relates to a method and device for increasing the quantity of electric charges in a chemical solution of an electrostatic sprayer. The method uses a liquid storage cavity of the electrostatic sprayer and an electrostatic module for generating static electricity. The liquid storage cavity is divided into a charging cavity and a chemical solution supply cavity. The charging cavity is isolated from the chemical solution supply cavity. An electrostatic output electrode of the electrostatic module applies static electricity to a chemical solution in the charging cavity in a static state so that the chemical solution carries a high content of electric charges. After the chemical solution carried with a high content of electric charges is sprayed out, the chemical solution in the chemical solution supply cavity is supplied into the charging cavity, so that the sprayed chemical solution is allowed to carry a high content of electric charges by charging static electricity to a small amount of the chemical solution in a stepped manner. In the method and device for increasing the quantity of electric charges in a chemical is solution of an electrostatic sprayer provided by the present invention, without changing the capacity, the quantity of electric charges in a part of the chemical solution in the liquid storage cavity is increased, the quantity of electric charges in the sprayed chemical solution is thus increased, and the absorption effect of the chemical solution is improved.
