Electrostatic dust collecting module an electrostatic air purifier thereof

An electrostatic precipitation module, comprising:

• a first connecting rib;
• a metal conductor embedded inside the first connecting rib along a length of the first connecting rib;
• a plurality of conductive precipitation electrode plates connected to the first connecting rib and distributed along the length of the first connecting rib;
• a first set of connecting frames between which the plurality of conductive precipitation electrode plates and the first connecting rib are disposed to form a precipitation electrode plate module;
• a second connecting rib;
• a plurality of non-precipitation electrode plates connected to the second connecting rib and distributed along a length of the second connecting rib;
• and
• a second set of connecting frames between which the plurality of non-precipitation electrode plates and the second connecting rib are disposed to form a non-precipitation electrode plate module,
• wherein, the precipitation electrode plates are made from conductive plastic material by injection molding, and the metal conductor is embedded inside the first connecting rib by in-mold injection molding,
• the non-precipitation electrode plates are made from conductive plastic material by injection molding,
• the precipitation electrode plate module is placed parallel and adjacent to the non-precipitation electrode plate module such that the plurality of non-precipitation electrode plates and the plurality of conductive precipitation electrode plates are interlacedly disposed.
