Similarly, when the arc-shaped racks are driven by the transmission gears to rotate counterclockwise by the same angle, all the transmission parts 452 on the rotary table 451 also rotate by the same angle, so as to drive all the air guide blades 420 to rotate from the horizontal state to the vertical state in the vertical plane, and thereby the blocking state of the first air duct 110 and the air outlet 140 is switched to the communication state.

Through the above arrangement, the rotation precision of the air guide blade 420 can be improved, so that the communication or the separation between the first air duct 110 and the air outlet 140 can be accurately switched, and the interference between the primary mode and the secondary mode of the air purifier 10 is further avoided.
