Electrostatic air purifier

The invention relates to an electrostatic air purifier, belongs to the technical field of air purification, and solves the technical problem that an existing electrostatic air purifier is poor in air purification efficiency. The electrostatic air purifier comprises a dust collection cover shell which is electrically connected with one electrode of a high-voltage generator, and an air inlet and an air outlet are formed in the dust collection cover shell; the mesh cage structure is installed in the dust collection cover shell and electrically connected with the other electrode of the high-voltage generator, and an air outlet channel communicated with the air outlet is formed between the mesh cage structure and the dust collection cover shell; the corona generating electrodes are connected to the mesh cage structure and are electrically connected with the mesh cage structure; and the air supply assembly is connected to the dust collection cover shell and located on the inner side of the mesh cage structure, and
