Detailed Description
The invention will now be described in detail with reference to fig. 1-7.
As shown in fig. 1-3, the present invention provides an electrostatic air purification plate 10, which comprises a plurality of electrostatic dust removal units arranged in an array, that is, a plurality of electrostatic dust removal units are arranged in an array, each electrostatic dust removal unit comprises a cylindrical cavity 11, a needle seat 12 and a discharge needle 13, the needle seat 12 is arranged at the center of the cylindrical cavity 11, and the discharge needle is arranged at the top end of the needle seat 12. The needle base 12 supplies power to the discharge needles 13, and compared with the traditional air purifier, the air purifier has the advantages that the purification plate is divided into a plurality of independent electrostatic dust removal units which are arranged in an array mode, and each cavity type is used for treating a part of air, so that the treatment efficiency can be effectively improved, and the air quality can be effectively improved. As long as the depth length of the cylindrical cavity is reasonably set, the air in different environments can be effectively treated. Meanwhile, the power required by each processing unit is reduced due to the distribution pattern, so that the power can be realized by using smaller voltage.
In the invention, the discharge needle comprises a needle plate 131 and a needle tip 132 arranged on the needle plate, and the needle plate 131 is fixed on the needle seat.
The needle point is arranged on the needle plate, so that the needle point can be conveniently and fixedly connected with the needle seat 12, meanwhile, the contact surface with the needle seat 12 is increased, and the needle seat is more stable when power is supplied through the needle seat.
The needle seat 12 can guide the air entering from the outside to move to a position close to the inner surface of the cylindrical cavity 11, thereby being more convenient for adsorption.
The electrostatic dust removal units are arranged in an array manner, the cylindrical cavities 11 are connected with each other, and the cylindrical cavities 11 can be conducted with each other, so that extra wires for configuring the cylindrical cavities can be omitted.
Fig. 3 is an array arrangement in an embodiment of the present invention, in the embodiment, the purification plate is composed of a plurality of rectangular electrostatic dust removal units, and the cross section of the cylindrical cavity is square, as can be seen from the figure, the cross section of the purification plate is in a shape composed of a plurality of squares.
