[0023] Please refer to Figure 1 , the threaded connection between the upper housing 1 and the lower housing 2 enables the upper housing 1 and the lower housing 2 to be detachable, facilitating the maintenance and replacement of the internal filtering device 6.

[0024] Please refer to Figure 2 , the filtering device 6 includes an outer filter housing 61, blades 62 and a filter element structure 63. A plurality of blades 62 are annularly arranged outside the outer filter housing 61. The blades 62 can play a role in guiding the incoming gas. A filter element structure 63 capable of filtering the air is installed inside the outer filter housing 61.

[0025] Please refer to Figure 3, the filter element structure 63 includes a driving component 631, a driven component 632, a filter element 633 and a motor 634. The bottom of the driving component 631 is connected to the output end of the motor 634. The motor 634 is installed on the lower housing 2 and is electrically connected to an external controller. One side of the driving component 631 is fitted with the driven component 632, and a filter element 633 capable of filtering gas is installed on the driven component 632.

[0026] Please refer to Figure 4 , the driving component 631 includes a mounting frame 11, a connecting shaft 12, a gear 13, a pin hole 14, a connecting frame 15, a sleeve 16, an L-shaped plate 17 and a dial 18. Connecting shafts 12 are installed at the centers of the upper and lower ends of the mounting frame 11. The bottom connecting shaft 12 is connected to the motor 634, and the mounting frame 11 can be driven to rotate by the motor 634. The top connecting shaft 12 is rotatably engaged with the gear 13. A connecting frame 15 is fixed to one side of the mounting frame 11, and a sleeve 16 is installed on the connecting frame 15. Two groups of L-shaped plates 17 are fixed to the other side of the mounting frame 11. The two groups of L-shaped plates 17 are symmetrically arranged and are both installed with dials 18.

[0027] Please refer to Figure 3 , a fixing column 131 is provided on the gear 13. The top end of the fixing column 131 is connected to the inner wall of the outer filter housing 61, which can play a role in installing and fixing the gear 13, so that when the mounting frame 11 rotates, the gear 13 will not rotate accordingly.

[0028] Please refer to Figure 5 , the driven component 632 includes a main shaft 21, a driving gear 22, a first bevel gear 23, a second bevel gear 24 and a rotating shaft 25. The main shaft 21 is installed in the sleeve 16 and is rotatably engaged with the sleeve 16. A driving gear 22 meshing with the gear 13 is fixed to the top of the main shaft 21. A first bevel gear 23 is installed at the bottom of the main shaft 21. A second bevel gear 24 is meshed with one side of the first bevel gear 23.

The filter element 633 is installed on the rotating shaft 25 and will rotate synchronously with the rotating shaft 25.

[0029] Please refer to Figures 3 - 5 , the motor 634 drives the connected mounting frame 11 to rotate. By means of the rotation of the mounting frame 11, the connecting frame 15 on one side will be driven to rotate synchronously. The connecting frame 15 will drive the driving gear 22 located inside it to make a circular motion around the gear 13, and drive the first bevel gear 23 at its bottom to rotate. Through the meshing of the first bevel gear 23 and the second bevel gear 24, the second bevel gear 24 and the filter element 633 connected to it will rotate together on the rotating shaft 25, so that the filter element 633 can increase the contact area and contact efficiency with the air and improve the filtering effect on the gas.

[0030] Example 2: Please refer to Figures 6 - 9 , the specific embodiments of the present invention are as follows: See also Figure 6 The outer filter shell 61 includes a mounting groove 611, a vibrating member 612 and a pre-filter screen 613. A plurality of mounting grooves 611 are arranged in a circular array on the cylinder wall of the outer filter shell 61. Vibrating members 612 are installed on one side of the plurality of mounting grooves 611 close to the inside of the filter shell, and pre-filter screens 613 are fixed on the plurality of mounting grooves 611.

[0031] See also Figure 6 The pre-filter 613 is made of metal mesh or nylon, which can intercept larger particles such as dust and hair in the incoming gas, and can protect the internal filter element 633 from being blocked prematurely.

[0032] See also Figure 7 The vibrating member 612 includes a mounting strip 31, an elastic column 32, a brush 33 and a spring 34. Two groups of mounting strips 31 are provided above and below. One side of the two groups of mounting strips 31 is fixed to the inner wall of the outer filter shell 61. A number of elastic columns 32 are installed between the two groups of mounting strips 31. A brush 33 is fixed on one side of the elastic columns 32 close to the pre-filter 613. A spring 34 is installed between each two adjacent groups of elastic columns 32.

[0033] See also Figure 7 The distances between the elastic columns 32 are the same, and they are all made of soft rubber, are elastic, and are in contact with the paddle 18 on the mounting frame 11. When the paddle 18 rotates with the mounting frame 11, it will contact the elastic column 32, and the elastic column 32 will vibrate left and right.

[0034] See also Figure 7 The brush 33 has a Y-shaped structure, and the forked brush heads at both ends can increase the contact area with the pre-filter 613. When the elastic column 32 vibrates left and right, it will drive the brush 33 to vibrate together, cleaning the dust adhered to the filter, thereby ensuring the filtering and interception effect of the pre-filter 613.

[0035] See also Figures 7 - 8 The two ends of the spring 34 are connected to two adjacent groups of elastic columns 32, which can connect several elastic columns 32 to form a whole, so that several elastic columns 32 are linked. When one elastic column 32 vibrates, the vibration force will be transmitted to the adjacent elastic column 32 with the help of the spring 34, thereby increasing the vibration effect of the elastic column 32, and with the help of the elastic potential energy of the spring 34 itself, the vibration force can be increased, making the vibration frequency of the elastic column 32 faster, thereby improving the cleaning effect of the brush 33 on the filter.

[0036] Based on the above embodiment, the specific working principle is as follows: When the vehicle air filter is in use, the air intake of the engine draws in the external air and enters the filter through the air intake pipe 4. The gas in the upper housing 1 is guided by the blades 62, so that the gas can fully contact the outer filter housing 61, and enter the inner filter element 633 through a plurality of pre-filters 613 installed on the outer filter housing 61 for deep filtration. The pre-filter 613 on the outer filter shell 61 is made of metal mesh or nylon to intercept larger dust and hair particles in the incoming gas. At the same time, the driving motor 634 drives the connecting shaft 12 and the installation frame 11 to rotate. The rotation of the installation frame 11 will drive the connecting frame 15 on one side to rotate synchronously. The connecting frame 15 will drive the driving gear 22 located inside it to make a circular motion around the gear 13. At this time, the main shaft 21 will drive the first bevel gear 23 at the bottom to rotate synchronously when rotating. Through the meshing of the first bevel gear 23 and the second bevel gear 24, the second bevel gear 24 and the rotating shaft 25 connected thereto will be driven to rotate on the installation frame 11, and the filter element 633 located on the rotating shaft 25 will be driven to rotate together, so that the filter element 633 can increase the contact area and contact efficiency with the air, thereby improving the filtering effect on the gas. When the mounting frame 11 is rotating, the paddle 18 on the mounting frame 11 will contact the elastic column 32 on the vibrating member 612, and the paddle 18 will move the elastic column 32 to vibrate left and right, and drive the brush 33 to vibrate together, so as to clean the dust adhering to the filter net, thereby ensuring the filtering and intercepting effect of the pre-filter 613, and the spring 34 on the elastic column 32 connects several elastic columns 32 into a whole, so that several elastic columns 32 are linked, increasing the vibration effect of the elastic column 32, making the vibration frequency of the elastic column 32 faster, and improving the cleaning effect of the brush 33 on the filter net. After the gas is filtered in the filter element 633, it will be discharged from the air outlet pipe 5 at the top of the shell.
