When the cross flow fan 3 works, air is sucked from the air inlet 11 to the air channel, air flow is formed in the air channel and blown to the air outlet 21, when the air flow passes through the plasma generator 5, positive and negative ions generated by the plasma generator 5 are taken out and blown out from the air outlet 21, and the ambient air is sterilized and purified by the positive and negative ions.

Wherein the air inlet 11 is provided at the bottom side of the rear case 1, and the air outlet 21 is provided at the upper side of the front cover 2. The structure enables the air purification sterilizer to intake air from the bottom and exhaust air from the upper side, thereby not only reducing dust falling into the air channel, but also forming an inverted L-shaped air channel in the shell. Compare the wind channel of straight line shape, thereby the shape of falling L wind channel lets the air current diversion in the wind channel slow down and can reduce the noise of air-out, improves user's use and experiences.
