Negative ion purification fan

The utility model discloses a negative ion purification fan which comprises a machine shell and a power wind set, the power wind set comprises a wind wheel arranged in the machine shell and a motor connected with the wind wheel, and the outer wall of the wind wheel is covered with a negative ion coating capable of generating negative ions. During use, the motor drives the wind wheel to rotate, air is drawn, meanwhile, the negative ion coating generates negative ions, the negative ions can enable dust particles with positive charges in the air to be coagulated and settled, air purification is achieved, the structure is simple, when the fan blades on the wind wheel rotate at a high speed, the negative ion coating can rub with the air at a high speed, and the purification effect is improved. 本实用新型公开了一种负离子净化风机，其包括：机壳和动力风组，动力风组包括设置于机壳内的风轮、与风轮连接的电机，所述风轮的外壁覆有可产生负离子的负离子涂层。在使用时，电机驱动风轮转动，实现对空气抽动，同时负离子涂层产生负离子，负离子能够使空气中带正电荷的粉尘微粒凝聚沉降，实现空气的净化，结构简单，风轮上的风叶高速转动时，负离子涂层可与空气高速摩擦，提高净化效果。
