[0042] The working principle of the above technical solution is:

[0043] A partition 2 is fixedly arranged in the middle of the shell 1, and the partition 2 divides the inner cavity of the shell 1 into a first air duct and a second air duct. Wind guide components are symmetrically arranged on both sides of the partition 2, and the wind guide components include a first wind guide cover 3, a wind wheel 5, a second wind guide cover 4 and an air filter 11 which are sequentially away from the partition.

A motor 9 is fixedly arranged in the motor compartment 8, and the motor 9 can be fixed in the motor compartment by bolts. The first air guide cover 3 can also be fixed to the partition 2 by bolts. The power output shaft of the motor 9 passes through the first air guide cover and extends to the side of the first air guide cover away from the partition 2. A vibration damping assembly 21 is arranged on the power output shaft of the motor. The vibration damping assembly 21 includes a vibration damping block 12, a vibration damping sleeve 13 and an annular connecting plate 14. The connecting block 16 is clamped in the connecting groove 15 for transmitting torque. The vibration damping block 12 and the vibration damping sleeve 13 are interference connected to limit the axial movement between the vibration damping block 12 and the vibration damping sleeve 13.

[0045] The vibration damping block 12 is detachably connected to the power output shaft of the motor 9, and an interference fit can be adopted between the vibration damping block 12 and the power output shaft of the motor 9; transmission planes in contact with each other can also be provided on the connecting hole of the vibration damping block 12 and the power output shaft of the motor 9 for transmitting torque, and a groove arranged along the circumferential direction is provided on the circumferential surface of the power output shaft of the motor 9, and a snap ring is clamped in the groove to limit the axial movement of the vibration damping block 12 on the power output shaft of the motor 9. The detachable transmission component on the power output shaft of the motor 9 is a prior art and will not be described in detail here.

[0046] The vibration-damping block 12 is made of a high molecular polymer material, so that the vibration of the motor cannot be transmitted to the wind wheel. Reducing the vibration of the wind wheel can improve the ventilation efficiency and reduce the noise of the wind wheel.

[0047] A control module compartment 18 is disposed at a distance from the motor compartment 8 on one side of the first air guide cover 3 that is recessed. The control module compartment 18 is used to install a control module that controls the operation of the air purifier.

[0048] The annular connecting plate 14 is fixedly arranged on the outer circumferential surface of the vibration damping sleeve 13, the annular connecting plate 14 is coaxially arranged with the vibration damping sleeve 13, the end surface of the annular connecting plate 14 away from the partition 2 is fixedly connected to the wind wheel 5, the wind wheel 5 and the annular connecting plate 14 can be connected by bolts, and the annular connecting plate 14 can be arranged at different positions of the outer circumference of the vibration damping sleeve 13 along the axial direction of the vibration damping sleeve 13 to adapt to the installation of the annular connecting plate 14 and the wind wheel 5.

[0049] A support leg 19 is fixedly arranged on the bottom surface of the shell 1, and the support leg 19 is arranged in four rectangular arrays. A second air inlet 20 is provided between the bottom surface of the shell 1 and the support leg 19. The support leg can maintain a certain distance between the bottom surface of the shell 1 and the ground, so that air can enter the shell from the second air inlet 20 on the bottom surface of the shell 1. The bottom surface of the shell 1 is detachably connected to the shell body, and after the bottom surface is removed, it can be used to install the air guide component of the shell.
