A filter assembly 8 is fixedly installed at the center of the top surface of the mounting plate 6, and a protective shell 9 is fixedly installed on the top surface of the mounting plate 6 and is sleeved on the outside of the filter assembly 8. The two threaded rods 4 are driven to rotate synchronously by the driving assembly to realize the lifting and lowering of the mounting plate 6. In conjunction with the box body 2, the filter assembly 8 can be retracted into the box body 2 when not in use, thereby improving the device's resistance to knocks and collisions. At the same time, the protective shell 9 can also improve the device's resistance to knocks and collisions when in use. Compared with existing devices, it avoids some bumps and collisions that may be encountered in daily life. The exposed air filter may be deformed due to bumps, which in turn leads to a problem of poor filtering effect, thereby improving the stability of the device.

[0022] Reference Figure 1-3 The driving assembly includes a sprocket 10 rotatably connected to both sides of the top wall of the cavity 5, and the sprocket 10 is fixedly sleeved on the bottom end of the threaded rod 4, and a chain 11 is commonly sleeved between the two sprockets 10. A motor 12 for driving one of the threaded rods 4 to rotate is fixedly installed on one side of the cavity 5. The rotation between the two sprockets 10 is synchronized by the chain 11, and then the two threaded rods 4 are driven to rotate by the motor 12, thereby realizing the up and down movement of the mounting plate 6.

[0023] The mounting plate 6 is fitted with the side walls of the box body 2 on all sides, and slide grooves 13 are provided on both side walls of the box body 2. Both sides of the mounting plate 6 extend into the slide grooves 13, and the slide grooves 13 can further improve the smoothness of the mounting plate 6 when moving.

[0024] The protective shell 9 wraps around the edge of the filter assembly 8, and the top of the protective shell 9 is arc-shaped and has rounded corners to improve the collision resistance of the device.

[0025] Reference Figure 4 The filter assembly 8 includes a filter layer 14 fixedly connected to one side of the mounting plate 6, and an adsorption layer 15 fixedly connected to the other side of the mounting plate 6. The filter layer 14 is made of non-woven fabric, which can intercept large particles of dust and achieve preliminary filtration of the air.

[0026] The adsorption layer 15 is made of activated carbon fibers, which remove harmful gases and odors from the air and improve the filtering effect of the air.

[0027] Working principle:

[0028] When using the air filter which is resistant to knocks and not easy to deform, turn on the motor 12, cooperate with the sprocket 10 and chain 11 to drive the two threaded rods 4 to rotate synchronously, and then drive the mounting plate 6 to move upward until the mounting plate 6 moves to the top of the slide groove 13, turn off the motor 12, and at this time, both sides of the filter component 8 are exposed to the outside, and the air passes through the filter layer 14, and the non-woven fabric intercepts large particles of dust. The air then passes through the adsorption layer 15, and the activated carbon fiber removes harmful gases and odors in the air, thereby filtering the air. After use, reverse the motor 12, cooperate with the sprocket 10 and chain 11 to drive the two threaded rods 4 to rotate synchronously until the filter component 8 is completely retracted into the box body 2, at this time, the knock resistance of the device is improved. The above is the entire use process of the air filter which is resistant to knocks and not easy to deform.

Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed in the present application according to the technical solution and utility model concept of the present application, which should be covered by the protection scope of the present application.
