DETAILED DESCRIPTION

[0021] The present invention is further described below with reference to specific embodiments. It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this patent, those skilled in the art may make various changes or modifications to the present invention, and that these equivalent forms also fall within the scope defined by the appended claims.

[0022] See also Figure 1 、 Figure 2 、 Figure 3This is a schematic diagram of the structure of the patent, an air filter protective cover with a dust-proof structure, including a ventilation duct 1 and an air filter plate 2. A slot 3 is opened on the upper wall of the ventilation duct 1, and the air filter plate 2 is inserted into the ventilation duct 1 through the slot 3;

[0023] The air filter plate 2 is directly inserted into the slot 3, so when it needs to be replaced, the air filter plate 2 can be easily taken out without disassembling the ventilation duct 1;

[0024] A dustproof plate 4 is inserted into the side wall of the ventilation duct 1. The dustproof plate 4 includes a plate body 41, a mounting groove 42 and a filter 43. The upper wall of the plate body 41 is provided with a mounting groove 42. The filter 43 is inserted and installed in the mounting groove 42. The side wall of the mounting groove 42 is provided with bristles 5. The bristles 5 are in contact with the side wall of the filter 43.

[0025] The dustproof plate 4 is set on one side of the air filter plate 2. The air needs to be initially filtered through the dustproof plate 4 before entering the ventilation duct 1, and then undergo secondary filtration through the air filter plate 2. The dustproof plate 4 can intercept larger impurities in the air, such as leaves, dead insects, etc., thereby effectively extending the service life of the filter element inside the air filter plate 2;

[0026] The filter 43 in the device can be pulled out from the mounting slot 42. During the pulling out process, the bristles 5 can clean the filter 43, making it convenient to clean the dust plate 4.

[0027] A rotating rod 6 is rotatably mounted on the side wall of the mounting groove 42, and the rotating rod 6 is in contact with the side wall of the filter screen 43. A first bevel gear 7 is mounted on the side wall of the rotating rod 6. A connecting rod 8 is mounted on the inner wall of the mounting groove 42. A fan blade 9 is rotatably mounted on the outer side of the connecting rod 8. A second bevel gear 10 is mounted on the outer side of the fan blade 9. The first bevel gear 7 is meshed with the second bevel gear 10.

[0028] By setting the fan blades 9, when the fan blades 9 rotate, the fan blades 9 will blow air in the direction of the clearance groove 11, so that the dust and other impurities brushed off by the bristles 5 are blown out through the clearance groove 11, thereby improving the cleaning effect;

[0029] At the same time, it can also prevent dust from falling back onto the dust screen 43;

[0030] A clearance groove 11 is formed on the side wall of the plate body 41 , and the clearance groove 11 is connected to the installation groove 42 .

[0031] One end of the insertion rod 12 is installed at the four corners of the plate body 41, and the other end of the insertion rod 12 is installed with a sphere 13. Sockets 14 are opened at the four corners of the side wall of the ventilation duct 1. The position of the socket 14 corresponds to the position of the insertion rod 12. Both the sphere 13 and the insertion rod 12 can be inserted and installed in the socket 14.

[0032] Blocks 15 are slidably mounted on the upper and lower sides of the inner wall of the jack 14. One end of a spring 16 is mounted on the side walls of the two blocks 15. The other end of the spring 16 is in contact with the inner wall of the jack 14.

[0033] The spring 16 provides a thrust to the clamping blocks 15 so that the two clamping blocks 15 clamp the sphere 13 , thereby fixing the plate 41 on the ventilation duct 1 .

[0034] A pull ring 17 is installed on the upper wall of the air filter plate 2;

[0035] The pull ring 17 can facilitate the staff to take the air filter plate 2 out of the slot 3.

[0036] The outer side of the rotating rod 6 is sleeved with a rubber sleeve 18, and the rubber sleeve 18 fits the side wall of the filter screen 43;

[0037] The rubber sleeve 18 increases the friction between the rotating rod 6 and the filter screen 43 so that the filter screen 43 can drive the rotating rod 6 to rotate when moving upward.

[0038] A pull plate 19 is installed at one end of the filter screen 43 located above the plate body 41 .

[0039] When the present invention is working, the filter 43 can perform a preliminary filtration on the air entering the ventilation duct 1, intercepting larger impurities in the air, such as leaves, dead insects, etc., and then the air after the preliminary filtration will enter the ventilation duct 1, pass through the internal air filter plate 2 for a secondary filtration, and then be discharged;

[0040] In order to avoid affecting the air intake of the ventilation duct 1, the filter 43 needs to be cleaned regularly. When cleaning, it is only necessary to pull the filter 43 out of the mounting groove 42. During the pulling-out process, the bristles 5 can clean the filter 43, making it convenient to clean the dustproof plate 4. In the pulling-out process, the filter 43 will drive the rotating rod 6 to rotate, so that it drives the fan blades 9 to rotate under the cooperation of the first bevel gear 7 and the second bevel gear 10. The fan blades 9 will blow air in the direction of the give way groove 11, so that the dust and other impurities brushed off by the bristles 5 are blown out through the give way groove 11, thereby improving the cleaning effect and preventing dust from falling back onto the dustproof net 43.
