Air purification device and air treatment equipment

The utility model discloses an air purification device and air treatment equipment. The air purification device comprises a shell; the first electrode is connected to the shell and is used for loading negative voltage; the second electrode is connected to the shell, and the second electrode and the first electrode are arranged at an interval and are used for being grounded or connected with a zero potential; the third electrode is connected to the shell, is arranged outside an area between the first electrode and the second electrode and is used for loading negative voltage; wherein the first electrode and the second electrode are jointly used for generating plasma, the third electrode is used for generating negative ions, and the distance between the third electrode and the second electrode is larger than or equal to 10 mm. The technical problem to be solved by the utility model is that the negative ion generator and the plasma generator are combined on the same module and then the negative ion discharge ele
