The moving rod 31 is fixedly connected to the inner wall of the device body 1, and a tooth groove is provided on the side of the moving rod 31 close to the fixed housing 44. The moving rod 31 is meshed with a gear 42, and the gear 42 is rotatably connected to the rotating rod 43. Notches 41 are provided on both sides of the fixed housing 44. The top of the rotating rod 43 is rotatably connected to the inner wall of the fixed housing 44. A T-shaped rod 48 is fixedly connected to the outer side of the fixed housing 44, and the top of the T-shaped rod 48 is fixedly connected to the cover plate 20. The inner wall of the fixed housing 44 is fixedly connected to a partition plate 46. The top end of the partition plate 46 does not contact the bottom end of the rotating wheel 47, and the rotating wheel 47 is rotatably connected to the rotating rod 43. The fixed housing 44 is provided with two groups of through holes 45, and a shunt pipe 30 is inserted into the interior of one group of through holes 45. The rear end of the shunt pipe 30 is communicated with the interior of the connecting pipe 25. The bottom end of the connecting pipe 25 is inserted into the solenoid valve 24, and the bottom end of the solenoid valve 24 is inserted into the gas tank 23. The gas tank 23 is fixedly connected to the rear end of the device body 1, and the front end of the connecting pipe 25 is fixedly connected to the delivery pipe 26.

[0037] Through the structural design of the guide mechanism, the function of guiding the compressed gas or gas pulse sprayed from the nozzle 27 is realized, the loss of gas during flow is reduced, and the air flow flowing to the bottom part of the bag body 29 can still maintain a high flow rate, so as to have a better cleaning effect on the bottom part of the bag body 29. During operation, the dust-containing gas enters the device body 1 through the air inlet 22. The larger dust particles will fall to the bottom of the device body 1 under the action of gravity for collection, while the smaller dust particles will be attached to the bag body 29. With the accumulation of dust particles on the bag body 29, the porosity of the bag body 29 will gradually decrease. At this time, the compressed gas or gas pulse is ejected from the nozzle on the bottom of the conveying pipe 26. The bag body 29 is blown out from the nozzle 27, thereby blowing the bag body 29 in the opposite direction and causing the bag body 29 to vibrate, and the dust particles attached to the bag body 29 will fall off, thereby completing the cleaning operation. When the compressed gas or gas pulse is ejected from the nozzle 27, the solenoid valve 24 is opened first, and the gas inside the gas tank 23 flows along the connecting pipe 25 and the delivery pipe 26. Since the connecting pipe 25 and the delivery pipe 26 are connected together and the shunt pipe 30 is connected to the connecting pipe 25, when the gas flows inside the delivery pipe 26, part of it will flow through the shunt pipe 30 to the inside of the fixed casing 44. The inside of the fixed casing 44 is divided into two chambers by the through hole 45. The gas will drive the rotating wheel 47 to rotate and be discharged from another set of through holes 45. The rotating wheel 47 and the gear 4 2 is fixed on the rotating rod 43. When the rotating wheel 47 drives the rotating rod 43 to rotate, the gear 42 will rotate synchronously. The gear 42 is partially meshed with the moving rod 31, thereby driving the two groups of moving rods 31 to move in opposite directions. The moving rod 31 is sleeved on the fixed rod 33 to support the movement of the moving rod 31, and a return spring 64 is sleeved on the fixed rod 33. At this time, the return spring 64 will be compressed. When the moving rod 31 moves, the top block 32 fixed at the bottom end thereof will abut against the abutment block 34 and push the abutment block 34 to move downward. The supporting spring 38 fixed on the bottom end of the moving sleeve 35 is compressed. At this time, the exhaust hole 40 opened on the moving sleeve 35 will be aligned with the exhaust hole 40 opened on the fixed sleeve 36, and the gas can pass through the moving sleeve 35. The movable sleeve 35 is smaller in radius than the bag body 29, so it can better guide the airflow ejected from the nozzle 27, so as to improve the dust cleaning effect on the bottom part of the bag body 29. Similarly, when the solenoid valve 24 is closed, the movable rod 31 will be reset under the action of the reset spring 64, and the movable rod 31 will move and drive the gear 42 to rotate in the reverse direction. When the top block 32 fixed at the bottom end of the movable rod 31 is no longer in contact with the abutment block 34, the movable sleeve 35 will move upward under the action of the support spring 38, so that the exhaust hole 40 opened on the movable sleeve 35 and the fixed sleeve 36 is no longer connected, so as to close the exhaust hole 40 of the fixed sleeve 36 to prevent dust from entering the movable sleeve 35.There are two groups of fixed shells 44, and both sides of the two groups of fixed shells 44 are provided with moving rods 31, and the moving rods 31 are symmetrically distributed along the central axis of the fixed shells 44.

[0038] Further, the vibration mechanism includes two groups of moving blocks 49, the moving blocks 49 are threadedly connected to the rotating rod 43, the rotating rod 43 passes through the mounting plate 62, the rotating rod 43 is provided with a thread at a position close to the top of the mounting plate 62, the bottom end of the rotating rod 43 is fixedly connected to the rotating disk 61, the rotating disk 61 is provided with a slot 59, the inside of the slot 59 is inserted with an insertion rod 58, the top part of the insertion rod 58 is T-shaped, the bottom end of the insertion rod 58 is fixedly connected with a sliding sleeve 56, the sliding sleeve 56 is sleeved on the connecting rod 57, both sides of the connecting rod 57 are rotatably connected to the swing rod 55, the bottom end of the swing rod 55 is rotatably connected to the support block 54, the bottom end of the support block 54 is fixedly connected to the support plate 53, and the support plate 53 is fixedly connected to the inner wall of the device body 1;

[0039] Through the structural design of the vibration mechanism, the function of repeatedly vibrating the bottom end portion of multiple groups of bag bodies 29 inside the device body 1 during the process of cleaning the inside of the device body 1 is realized, so that the dust attached to the bottom end portion of the bag body 29 can be quickly shaken off and then fall into the bottom end of the inside of the device body 1 for collection, thereby improving the cleaning effect of the bottom end portion of the bag body 29. When working, the rotation of the rotating rod 43 will be transmitted to the rotating disk 61 fixed on the bottom end. When the rotating disk 61 rotates The insertion rod 58 will make a circular motion along the central axis of the rotating disk 61, the insertion rod 58 will move up and down in the slot 59, the sliding sleeve 56 fixed on the bottom end of the insertion rod 58 will slide back and forth on the connecting rod 57, and the connecting rod 57 is rotatably connected to the swing rod 55, and the swing rod 55 is rotatably connected to the support block 54, so that the two sets of swing rods 55 can be driven to swing back and forth, and the swing rod 55 can slap the bottom end part of the bag body 29, so that the dust attached to the bottom end of the bag body 29 can be quickly shaken off.

[0041] The structural design of the sealing mechanism realizes the function of sealing the support plate 53 during the dust cleaning process inside the device body 1, so that the airflow above the support plate 53 will not flow to the bottom of the support plate 53 during dust cleaning, to ensure that the airflow will not blow the dust accumulated under the support plate 53. During operation, the rotation of the rotating rod 43 will drive the moving block 49 threadedly connected on the rotating rod 43 to move upward. The two groups of moving blocks 49 are connected together by the connecting rod 65 and the long rod 50 is fixed at the bottom end of the connecting rod 65. The bottom end of the long rod 50 is connected to the sealing block 52. Therefore, when the moving block 49 moves upward, the sealing block 52 will be lifted upward synchronously until the top of the sealing block 52 blocks the bottom end of the support plate 53. At this time, the airflow inside the device body 1 will not flow to the bottom of the support plate 53 through the support plate 53, to avoid the airflow blowing the dust collected under the support plate 53.

[0042] Furthermore, the top of the sealing block 52 is conical, the bottom of the sealing block 52 is hollow, and a discharge port is provided at the bottom of the support plate 53, the size of which is adapted to the sealing block 52;

[0043] During operation, the top of the sealing block 52 is conical so that dust falling onto the bottom of the support plate 53 can pass through the sealing block 52 smoothly, and the bottom of the sealing block 52 is hollow so as to reduce the weight of the sealing block 52 itself.

[0045] During operation, the long rod 50 passes through the retaining frame 51 to prevent the long rod 50 from shaking greatly during its rotation, thereby ensuring that the sealing block 52 can accurately close the discharge port on the bottom end of the support plate 53.

[0046] Furthermore, the bottom end of the nozzle 27 contacts the stopper 63, and the bottom end of the stopper 63 is fixedly connected to the top end of the moving rod 31;

[0047] During operation, the stopper 63 is not located directly below the nozzle 27 . When the moving rod 31 moves, the stopper 63 will be away from the nozzle 27 , so as to ensure the normal operation of the nozzle 27 .

[0048] Furthermore, the rotating disk 61 is provided with a plurality of groups of circular holes 60, and the circular holes 60 are distributed in a circumferential manner on the rotating disk 61;

[0049] During operation, the rotating disk 61 is provided with a plurality of groups of circular holes 60 to ensure that the dust on the rotating disk 61 can fall through the circular holes 60 , thereby preventing the dust from accumulating on the top of the rotating disk 61 .
