AIR PURIFIER AND BLOWER DEVICE THEREOF

The disclosure relates to an air purifier and a blower device thereof. The blower device comprises a first fan (1) and a second fan (2) which have a same blowing direction and are arranged sequentially in the air blowing direction at an interval. The first fan (1) and the second fan (2) are mounted coaxially and driven synchronously by a motor (3). By adopting the two fans provided at the interval and driven synchronously by one motor, the blowing effectiveness of the air purifier can be improved significantly, and a simple structure and good availability can be obtained.
