[0042] It can be understood that in the present application, the output shaft of the drive motor 920 movably passes through the fixed seat 904 and is fixedly installed with a second bevel gear 919. The second bevel gear 919 meshes with the first bevel gear 918. One side surface of the first bevel gear 918 is fixedly installed on one end surface of the movable sleeve column 917. The movable sleeve column 917 is movably installed at the center of the movable turntable 905. The drive motor 920 cooperates with the first bevel gear 918 and the second bevel gear 919 to drive the movable sleeve column 917 to rotate.

[0043] It can be understood that in the present application, a threaded rod 916 is movably installed inside the movable sleeve column 917. One end of the threaded rod 916 away from the movable sleeve column 917 is fixedly installed with a gear disk 909. The gear disk 909 meshes with a second tooth 911. The second tooth 911 is fixedly installed inside the connecting turntable 921. The connecting turntable 921 is movably installed inside the fixed housing 13 through balls. A number of first teeth 903 are fixedly installed on one side surface of the gear disk 909 away from the threaded rod 916. The first teeth 903 mesh with one end of the clamping mechanism 8.

[0044] It can be understood that in the present application, a number of connecting columns 902 are fixedly installed on one side surface of the connecting turntable 921 away from the fixed housing 13. One end of the connecting column 902 away from the connecting turntable 921 movably passes through the equipment housing 2 and is fixedly installed with a movable disk 901. A number of clamping mechanisms 8 are fixedly installed on one side surface of the movable disk 901 away from the connecting column 902.

[0045] It can be understood that in the present application, a disc 907 is fixedly installed on the output shaft of the servo motor 908. The outer surface of the disc 907 is movably installed with a first belt 906. The inner surface of the other end of the first belt 906 is movably installed on the outer surface of the movable turntable 905. One side of the movable turntable 905 is movably installed on the end surface of one end of the fixed seat 904 through a rotating shaft. Both ends of the side of the movable turntable 905 away from the fixed seat 904 are fixedly installed with a rectangular connecting column 912. The end of the rectangular connecting column 912 away from the movable turntable 905 is fixedly installed with a fixed sleeve 910. A plurality of rectangular grooves 915 are formed inside the fixed sleeve 910. A rectangular protruding block 914 is movably installed inside each rectangular groove 915. The rectangular protruding block 914 is integrally arranged on the outer surface of the connecting sleeve 913. One end of the connecting sleeve 913 is fixedly installed on the side surface of the gear disc 909 and the connecting sleeve 913 is sleeved on the outer surface of the threaded rod 916. The servo motor 908 will drive the first belt 906 to rotate in cooperation with the disc 907. During the rotation of the first belt 906, it will drive the two rectangular connecting columns 912 to rotate together in cooperation with the movable turntable 905. At this time, the rectangular connecting column 912 will drive the clamping mechanism 8 to rotate in cooperation with the gear disc 909, the connecting turntable 921 and the movable disc 901. At this time, since the filter element 7 is installed inside the clamping mechanism 8, it will rotate together. When the filter element 7 rotates, the side with dust will gradually turn towards the dust discharge port 10. At this time, the clean air at the center of the filter element 7 will backwash the side of the filter element 7 with dust, so that the dust is discharged from the dust discharge port 10, increasing the service life of the filter element 7 and at the same time increasing the filtering efficiency.

[0046] As Figure 5 , Figures 8 to 11 shown, the clamping mechanism 8 includes a clamping rod 801, a protective housing 802, a sliding column 804 and a left - right threaded rod 805;

[0047] The protective housing 802 is fixedly installed on the side surface of the movable disc 901. A sliding column 804 is fixedly installed on both sides inside the protective housing 802. A left - right threaded rod 805 is movably installed between the two sliding columns 804. A clamping rod 801 is movably installed at both ends of the left - right threaded rod 805 and the sliding column 804. The two clamping rods 801 are respectively clamped on both sides of the center of the I - shaped rubber ring 12. The I - shaped rubber ring 12 is fixedly installed on the end surface of one end of the filter element 7. The gear disc 909 will drive the gear 809 in the clamping mechanism 8 to rotate in cooperation with the first tooth 903. The gear 809 will drive the left - right threaded rod 805 to rotate in cooperation with the second belt 807 and the first turntable 806.

[0048] It can be understood that in the present application, one end of each of the clamping rods 801 can move through a rectangular slide 803, and the two rectangular slides 803 are conveniently opened at both ends of one side of the protective shell 802. One end of the positive and negative threaded rods 805 is fixedly installed with a first turntable 806, and a second belt 807 is movably installed on the outer surface of the first turntable 806. The second turntable 808 is movably installed on the inner surface of the other end of the second belt 807. A gear 809 is fixedly installed on one side surface of the second turntable 808 through a connecting rod. The side of the gear 809 away from the second turntable 808 is movably mounted on the side of one end of the elliptical fixed block 810 through a rotating axis, and the end of the elliptical fixed block 810 away from the gear 809 is fixedly mounted on the surface of one side of the movable disc 901. The positive thread and the negative thread of the positive and negative threaded rod 805 will respectively drive a clamping rod 801 to move outward, so as to facilitate the loosening of the filter element 7 for replacement. During installation, the transmission motor 920 is flipped to clamp the I-shaped rubber ring 12 fixedly mounted on one end of the filter element 7, thereby fixing it.

[0049] like Figure 12 As shown, the positioning mechanism 11 includes a placement slot 1101, a limiting slot 1102, a limiting rod 1103 and a return spring 1104;

[0050] The placement groove 1101 is opened inside one side of the elliptical fixed block 810, and the limiting groove 1102 is opened inside one side of the gear 809. A limiting rod 1103 is movably installed at one end of the placement groove 1101, and a reset spring 1104 is fixedly installed between the limiting rod 1103 and the placement groove 1101. The end of the limiting rod 1103 away from the reset spring 1104 is movably installed inside the limiting groove 1102. Both sides of the limiting groove 1102 and both sides of one end of the limiting rod 1103 are provided with inclined surfaces. When the fixation is completed, the limiting rod 1103 in the positioning mechanism 11 will be clamped in the inside of the limiting groove 1102. Since there is no driving force on the I-shaped rubber ring 12, it will be fixed at this time to prevent the filter element 7 from shaking during rotation.

[0051] Working principle:

[0052] First, the air suction device 5 fixedly installed on one side of the air inlet pipe 3 is turned on. At this time, the air suction device 5 will suck the dusty air from the air inlet pipe 3 into the interior of the equipment housing 2. At this time, the dusty air will pass through the filter element 7 to filter the dust in the center of the dusty air. Then, the clean air will be discharged from the center of the filter element 7 to the clean air discharge pipe 1 to ensure the quality of the air.

[0053] When the air suction device 5 is started, the servo motor 908 in the balanced rotating mechanism 9 will be started at the same time. At this time, the servo motor 908 will cooperate with the disc 907 to drive the first belt 906 to rotate. During the rotation process, the first belt 906 will cooperate with the movable turntable 905 to drive the two rectangular connecting columns 912 to rotate together. At this time, the rectangular connecting column 912 will cooperate with the gear plate 909 and the connecting turntable 921 and the movable disc 901 to drive the clamping mechanism 8 to rotate. At this time, since the filter element 7 is installed inside the clamping mechanism 8, it will rotate together. When the filter element 7 rotates, the dust-containing side will gradually turn to the dust discharge port 10. At this time, the clean wind at the center of the filter element 7 will backwash the dust-containing side of the filter element 7, and the dust has been discharged from the dust discharge port 10, thereby increasing the service life of the filter element 7 and increasing the filtration efficiency.

[0054] When the filter element 7 is aged and needs to be replaced, the clean air discharge pipe 1 movably installed by the clamp is removed, and the transmission motor 920 rotates at this time, and the transmission motor 920 cooperates with the first bevel gear 918 and the second bevel gear 919 to drive the movable sleeve column 917 to rotate, and the movable sleeve column 917 drives the threaded rod 916 to move outward when rotating. At this time, the gear plate 909 cooperates with the first tooth 903 to drive the gear 809 in the clamping mechanism 8 to rotate, and the gear 809 cooperates with the second belt 807 and the first rotating disk 806 to drive the positive and negative threaded rod 805 to rotate. At this time, the positive thread and the negative thread of the positive and negative threaded rod 805 will respectively drive a clamping rod 801 to move outward, so as to facilitate the loosening of the filter element 7 for replacement. When installing, the transmission motor 920 is turned over to clamp the I-shaped rubber ring 12 fixedly installed at one end of the filter element 7, thereby fixing it;

[0055] After the fixing is completed, the limiting rod 1103 in the positioning mechanism 11 will be clamped in the limiting groove 1102. Since there is no driving force on the I-shaped rubber ring 12, it will be fixed at this time to prevent the filter element 7 from shaking during rotation;

[0056] Therefore, the dust will not gradually clog the filter holes after long-term use, and the service life and filtering efficiency will be increased.

[0057] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
