An electrostatic precipitator 10 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in fig. 1-3, an electrostatic precipitator 10 according to an embodiment of the present invention includes a plurality of electrode units 100, the plurality of electrode units 100 includes at least one high potential unit 110 and at least one low potential unit 120, the plurality of electrode units 100 are disposed at intervals, the high potential unit 110 and the low potential unit 120 are alternately arranged, and a dust-removing air duct is formed between adjacent electrode units 100; wherein each electrode unit 100 comprises a conductive part 101 and an insulating part 102, the conductive part 101 comprises an electric field generator (not shown) and a conductive protrusion 1011, and the insulating part 102 covers at least a part of the electric field generator (not shown). The conductive members 130, the conductive members 130 are respectively connected to the plurality of conductive protrusions 1011; conductive member 130 includes a positioning member 131 and a conductive strip 132, conductive strip 132 is disposed through positioning member 131, and conductive protrusion 1011 is provided with a first groove 1012 matching conductive strip 132.

In other words, some of the electrode units 100 may be the high potential unit 110, some of the electrode units 100 may be the low potential unit 120, that is, the electrode unit 100 adjacent to the high potential unit 110 is the low potential unit 120, and the electrode unit 100 adjacent to the low potential unit 120 is the high potential unit 110, for example, the arrangement of the electrode units 100 is as follows: the high potential units 110, the low potential units 120, the high potential units 110, and the low potential units 120 are alternately arranged in sequence. A dust removal air duct is formed between the adjacent electrode units 100.

Each electrode unit 100 includes a conductive portion 101 and an insulating portion 102, the conductive portion 101 includes a conductive protrusion 1011 and an electric field generator (not shown), and the insulating portion 102 covers at least a portion of the electric field generator (not shown).

It is understood that the conductive protrusion 1011 refers to a portion of the conductive part 101 for achieving electrical conduction, mainly for an electrical connection site. The electric field generator (not shown in the figure) refers to a portion of the conductive portion 101 for generating an electric field.

The conductive members 30, the conductive members 130 are respectively connected to the plurality of conductive protrusions 1011; conductive member 130 includes a positioning member 131 and a conductive strip 132, conductive strip 132 is disposed through positioning member 131, and conductive protrusion 1011 is provided with a first groove 1012 matching conductive strip 132.

Because a high-voltage electric field can be generated between the adjacent electrode units 100 of the electrostatic dust collector 10, air molecules can be ionized into positive ions and negative ions through the high-voltage electric field, when the negative ions are in contact with bacteria, molds, viruses and the like, the negative ions carry redundant electrons, molecular protein structures in the bacteria, the molds, the viruses and the like can be damaged, structural change (two polarities of proteins are reversed) or energy transfer is generated on the bacteria, the molds, the viruses and the like, and therefore microorganisms such as bacteria, viruses and the like can die. Therefore, the electrostatic precipitator 10 has a sterilizing effect, thereby improving the cleanliness of air. In addition, since the dust removing air duct extends along the length direction (for example, the left-right direction in fig. 1) of the adjacent high potential unit 110 and low potential unit 120, the wind resistance of the electrostatic dust collector 10 can be reduced, so as to improve the dust removing efficiency, and since the wind resistance of the electrostatic dust collector 10 is small, the flow velocity of the air at the electrostatic dust collector 10 is fast, so as to ensure that the air sterilization effect is good in the same time.
