[0037] As Figure 1 , Figure 4 , Figure 5 and Figure 6 shown, as a specific technical solution, the lifting mechanism 2 includes a fixed shell 202 fixedly connected to the outer wall of the air box pulse dust collector body 1; a linear module is arranged in the fixed shell 202, the linear module is provided with a movable seat 204, and the movable seat 204 is fixedly connected with a movable bar 201.

The bottom of the fixed shell 202 is fixedly communicated with a receiving bottom cylinder 205; when the movable seat 204 moves to the lowest position, the receiving bottom cylinder 205 is used for the entry of the second cylinder body 501 to provide a receiving space for the second cylinder body 501.

[0038] The motor 203 drives the screw rod 206 to rotate, the screw rod 206 is screwed with the threaded hole 2041, and in cooperation with the vertical sliding of the movable bar 201 in the sliding groove 104 and under the guiding action, the movable seat 204 and the movable bar 201 can move up and down together, and then the movable bar 201 drives the brushing mechanism 4 to brush on the filter cartridge 102 to achieve brushing and cleaning.

[0039] Among them, the motor 203 is a servo motor with a brake or provided with a worm and worm gear, and it has a self-locking function.

[0040] As Figures 4-6 shown, as a specific technical solution, the blocking mechanism 3 includes a fixed frame 303; the number of the fixed frames 303 is two, the two fixed frames 303 are respectively located above and below the fixed shell 202, and both of the two fixed frames 303 are fixedly connected with the outer wall of the air box pulse dust collector body 1. Two support rollers 302 are rotatably installed on both of the two fixed frames 303, the shielding belt 301 is wound around the four support rollers 302, and the shielding belt 301 is fixedly connected with the movable bar 201. Grooves are formed at the top and bottom of the fixed shell 202 for the shielding belt 301 to pass through.

[0041] When the movable bar 201 drives the brushing mechanism 4 to move up and down, in cooperation with the four supporting rollers 302, the shielding belt 301 also moves together with the movable bar 201. Through the above design, the chute 104 is always shielded and blocked, and the up and down movement of the movable bar 201 is not affected, preventing the dust in the air box pulse dust collector body 1 from entering the fixed housing 202 through the chute 104, playing a role in dust blocking.

[0042] As Figures 8-13 shown, as a specific technical solution, the brushing mechanism 4 includes a circular ring housing 401 fixedly connected to the end of the movable bar 201; an annular orifice plate 404 is fixedly installed on the inner ring of the circular ring housing 401, and a plurality of carrier strips 405 are arranged in an annular array inside the circular ring housing 401. A plurality of the carrier strips 405 are respectively fixedly connected to a plurality of groups of bristles 402, and the bristles 402 penetrate through the through holes on the annular orifice plate 404; a plurality of telescopic members are also arranged in an annular array inside the circular ring housing 401, and a plurality of the telescopic members are respectively connected to a plurality of the carrier strips 405.

[0043] As Figures 11-12 shown, as a specific technical solution, the telescopic member includes a fixed seat 406 fixedly connected to the outer wall of the inner ring of the circular ring housing 401. The fixed seat 406 is fixedly connected to a first cylinder 403. A first piston 408 is connected in the first cylinder 403 in a matching manner. The first piston 408 is fixedly connected to a first movable rod 407. The first movable rod 407 penetrates through a first hole formed at one end of the first cylinder 403 away from the fixed seat 406. The first movable rod 407 is fixedly connected to the carrier strip 405. A first spring 409 is arranged in the first cylinder 403, and the first piston 408 is elastically connected to the end face of the first cylinder 403 through the first spring 409.

[0044] As Figure 4 、 Figure 5 and Figure 7As shown in the figure, as a specific technical solution, it further includes an air extraction mechanism 5, and the air extraction mechanism 5 includes a second cylinder body 501; the second cylinder body 501 is fixedly installed on the movable seat 204, a partition 504 is fixedly installed in the second cylinder body 501, and a cavity is formed by the inner wall of the second cylinder body 501 and one side of the partition 504. The cavity is connected with a second piston 505 in a matching manner. The bottom of the second piston 505 is elastically connected to the inner wall of the bottom of the second cylinder body 501 through a second spring 507. A U-shaped connecting rod 506 is fixedly installed at the bottom of the second piston 505. One end of the connecting rod 506 away from the second piston 505 is fixedly connected to a second movable rod 502. The second movable rod 502 passes through a second hole formed in the top of the second cylinder body 501, and the second movable rod 502 extends above the second cylinder body 501. A bottom groove 5011 is formed in the bottom of the second cylinder body 501, and the connecting rod 506 is slidably connected to the bottom groove 5011.

[0045] As Figure 7 , Figure 11 and Figure 12 shown in the figure, as a specific technical solution, a connecting pipe 503 is arranged inside the movable strip 201 and the movable seat 204, and one end of the connecting pipe 503 is communicated with the top of the cavity. The other end of the connecting pipe 503 extends into the circular ring shell 401. A circular ring pipe 7 is fixedly installed on the outer circumferential inner wall of the circular ring shell 401. The connecting pipe 503 is fixedly communicated with the circular ring pipe 7. A plurality of interfaces 701 are arranged on the inner circle of the circular ring pipe 7 in an annular array distribution. The circular ring pipe 7 is communicated with one end of the first cylinder body 403 away from the carrier strip 405 through the interfaces 701.

[0046] As Figure 2 shown in the figure, when the brushing mechanism 4 is located at the bottom end of the top cylinder 103, the top end of the second movable rod 502 of the air extraction mechanism 5 just contacts the inner wall of the top of the fixed shell 202. At this time, the air extraction mechanism 5 does not extract air from the first cylinder body 403, the telescopic member is in an extended state, and the brush hair 402 extends out of the fixed shell 202, as Figures 8-9 shown in the figure; When the brush sweeping mechanism 4 is driven to move downward, the dust on the filter cartridge 102 can be swept downward by the bristles 402 to achieve cleaning; and when the brush sweeping mechanism 4 is driven to move upward until the annular shell 401 moves to the top of the top cylinder 103, the movable seat 204, the movable bar 201 and the air extraction mechanism 5 will move upward together, and through the obstruction of the top inner wall of the fixed shell 202, the second movable rod 502 moves toward the inside of the second cylinder 501, that is, the second movable rod 502 moves downward relative to the second cylinder 501, and the second movable rod 502 drives the second piston 505 to move downward in the cavity through the connecting rod 506, and the connecting rod 506 slides with the bottom groove 5011 to provide guidance; and the second piston 505 moves downward, so that the cavity enters. The air is evacuated and the second spring 507 is compressed. The cavity evacuates the first cylinder 403 through the connecting tube 503, the annular tube 7, and the interface 701, and cooperates with the external atmospheric pressure to make the first piston 408, the first movable rod 407, the carrier bar 405 and the bristles 402 move away from the axis of the annular shell 401. The telescopic rod completes the contraction, and the bristles 402 enter the annular shell 401. At the same time, the first spring 409 is compressed, and the bristles 402 move into the annular shell 401. The bristles 402 can enter the annular shell 401 through the through holes on the annular orifice plate 404, and the dust and dirt hidden in the bristles 402 will be blocked by the annular orifice plate 404, and the hidden dirt can be pushed down to achieve cleaning, thereby ensuring the cleanliness of the bristles 402.

[0047] The through hole is adapted to the bristles 402 and can only ensure the passage of the bristles 402 .

[0048] In the process of the brushing mechanism 4 moving from the top end to the bottom end of the top cylinder 103, the second piston 505, the connecting rod 506 and the second movable rod 502 can be driven to reset by the compression elastic force of the second spring 507, and return to the state as shown in FIG. Figure 7 As shown; at the same time, the second piston 505 moves upward in the cavity, injects the gas in the cavity into the connecting tube 503, and is injected into the first cylinder 403 through the connecting tube 503, the annular tube 7, and the interface 701. With the compression force of the first spring 409, the first piston 408, the first movable rod 407, the carrier bar 405 and the bristles 402 are moved close to the axis of the annular shell 401, the telescopic rod is extended, and the bristles 402 extend out from the annular shell 401.

[0049] During the daily use of the main body 1 of the air box pulse dust collector, the brushing mechanism 4 is located at the top of the top cylinder 103. After the bristles 402 complete self-cleaning, they are stored in the circular ring shell 401. The circular ring shell 401 provides protection for the bristles 402 and reduces the dust adhering to the bristles 402. When the filter cartridge 102 needs to be cleaned, the brushing mechanism 4 moves downward to the bottom of the top cylinder 103, and the bristles 402 extend. The brushing mechanism 4 continues to move downward, and the dust on the outer wall of the filter cartridge 102 can be brushed downward for cleaning. After cleaning, the brushing mechanism 4 is restored to the top position of the top cylinder 103, and the self-cleaning and protection after self-cleaning of the bristles 402 are continued.

[0050] As Figure 11 shown, as a specific technical solution, each of the plurality of partition strips 6 is connected with a transmission mechanism 8. The transmission mechanism 8 includes a second rack 803; one end of the second rack 803 is fixedly connected with the carrier strip 405. The second rack 803 is meshed with a gear 802. An installation frame is fixedly connected to the wall of the circular ring shell 401. The installation frame is rotatably connected with the gear 802. The gear 802 is meshed with a first rack 801. One end of the first rack 801 is fixedly connected with a guide sleeve 804. A guide rod 805 is fixedly installed in the circular ring shell 401. The guide sleeve 804 is slidably sleeved on the guide rod 805. A long groove is formed in the second rack 803 along the length direction. The long groove is connected with a guide post 806 in a clearance fit manner, and the end of the guide post 806 is fixedly connected with the side wall of the circular ring shell 401. One end of the first rack 801 is fixedly connected with a connecting column 807, and the connecting column 807 is fixedly connected with the partition strip 6.

[0051] As Figure 11 shown, as a specific technical solution, a plurality of through grooves 4011 and a plurality of inner grooves 4012 are formed in both the top and bottom of the circular ring shell 401; the connecting column 807 is slidably connected with the through groove 4011. The inner groove 4012 is divided into two parts. One part of the inner groove 4012 is located on one side of the through groove 4011, and the other part of the inner groove 4012 runs through the through groove 4011 in the horizontal direction.

[0052] As Figure 11 shown, as a specific technical solution, the connecting column 807 is fixedly connected with a movable plate 808, and the movable plate 808 is slidably installed in the inner groove 4012.

[0053] Among them, the number of partition strips 6 is twice the number of carrier strips 405. Both the upper and lower parts of a single carrier strip 405 are connected with a partition strip 6 through a transmission mechanism 8. When a plurality of carrier strips 405 move radially along the circular ring shell 401, the two groups of partition strips 6 on the upper and lower parts of the circular ring shell 401 can be driven to move.

[0054] Among them, when the brushing mechanism 4 is in an idle state, that is, at the top of the top cylinder 103, the annular groove formed by the inner ring of the circular ring shell 401 and the outer ring of the top cylinder 103 is blocked above and below the annular groove by two partition parts.

[0055] The purpose of the blocking is that there may be a gap between the through holes on the annular orifice plate 404 and the bristles 402. Through this blocking, the entry of dust into the gap is reduced, achieving the effect of improving dust-proof protection.

[0056] Specifically, when the bristles 402 extend out from the circular ring shell 401, as Figure 8 and Figure 11 shown, the partition strip 6 has not moved to the annular groove, and the partition strip 6 covers the through groove 4011; when the bristles 402 are retracted into the circular ring shell 401, the carrier strip 405 drives the second rack 803 to move away from the axis direction of the circular ring shell 401. Through the meshing transmission between the second rack 803 and the gear 802, the gear 802 rotates. Through the meshing transmission between the gear 802 and the first rack 801, the first rack 801, the connecting column 807, and the partition strip 6 move together towards the axis direction of the circular ring shell 401. The partition strip 6 moves to the annular groove, and when several partition strips 6 all move to the annular groove, the formed circular ring-shaped partition part can block and protect the annular groove; at the same time, during the process when the partition strip 6 leaves the through groove 4011, the movable plate 808 moves together with the connecting column 807. The movable plate 808 slides in the inner groove 4012. When the movable plate 808 moves to the part where the inner groove 4012 penetrates the through groove 4011, it blocks the through groove 4011, preventing dust from entering the circular ring shell 401 through the through groove 4011 after the through groove 4011 loses the blocking of the partition strip 6.

[0057] During the process when the bristles 402 extend out from the circular ring shell 401, the carrier strip 405 drives the second rack 803 to move towards the axis direction of the circular ring shell 401. Through the meshing transmission between the second rack 803 and the gear 802, the gear 802 rotates. Through the meshing transmission between the gear 802 and the first rack 801, the first rack 801, the connecting column 807, and the partition strip 6 move together away from the axis of the circular ring shell 401. The partition strip 6 moves to the through groove 4011, leaving the annular groove, and the partition strip 6 re-blocks the through groove 4011.

[0058] Through the above design, while the bristles 402 are retracted, the annular groove is automatically blocked and protected, and when the bristles 402 leave the circular ring shell 401, the blocking of the annular groove can be automatically cancelled.
