[0012] Preferably, the method for using the ventilation and dustproof fire pump control cabinet comprises the following steps: S1: Driven by the driving motor, the air inlet fan in the air inlet chamber can rotate, so that the air outside the control cabinet shell enters the air inlet chamber through the ventilation chamber, and the air circulates in the control cabinet shell. When the driving motor rotates, the main shaft of the driving motor drives the driving disk to rotate, and the driving belt makes the rotating disk rotate synchronously, thereby making the rotating rod rotate. The rotation of the rotating rod drives the rotating sleeve to rotate, and the moving sleeve ring clamped on the rotating rod is close to the rotating disk. At this time, the articulated frame on the moving sleeve ring drives the two connecting frames on the rotating disk to move on the rotating disk toward the inner wall of the rotating sleeve. When the end face of the connecting frame contacts the inner wall of the rotating sleeve When the rotating sleeve rotates, the movable sleeve ring can be driven to rotate, and the movable sleeve ring is clamped on the rotating rod, so that the rotating rod can rotate synchronously. When the rotating rod rotates, the rotating rod will drive the mounting shaft to make the torsion spring rotate in the annular groove and expand outward, so that the torsion spring is in a stressed state. The clamping block arranged at the end of the torsion spring is initially arranged in the notch in the inner wall of the annular groove. The mounting shaft drives the clamping block on the torsion spring to move along the notch in the annular groove. When the torsion spring reaches the critical point, the clamping block on the torsion spring will move to the next notch in the annular groove, thereby avoiding damage to the torsion spring caused by overload. S2: The baffle portion on the wind baffle is located in the air inlet cavity. When the air inlet fan rotates to allow air outside the control cabinet housing to enter the air inlet cavity, the air will contact the baffle portion. The baffle portion forms resistance to the air, which will cause the connecting portion to deflect counterclockwise on the carrier. When the connecting portion rotates counterclockwise on the carrier, the two slide grooves on the connecting portion will drive the moving rod to move the moving block toward the direction of the rotating sleeve. At this time, the moving block will drive the moving sleeve ring on the rotating rod to move toward the direction of the rotating sleeve, squeezing the connecting spring to make the connecting frame contact with the inner wall of the rotating sleeve, so that the rotating sleeve can drive the rotating rod to rotate; S3: When the connecting portion of the wind deflector rotates counterclockwise on the carrier, the telescopic block on the connecting portion drives the connecting rod to move the limit block toward the side of the adjusting rack provided with the protrusion. At this time, the stop block abuts against the bottom of the protrusion, thereby limiting the adjusting rack and restricting the moving rack on the carrier; S4: When too much dust accumulates on the filter screen and affects the wind flow in the air inlet chamber, the connecting spring arranged between the rotating disk and the movable sleeve ring will push the movable sleeve ring to move in the direction away from the rotating sleeve disk. The movement of the movable sleeve ring will pull the hinged frame to separate the connecting frame from the inner wall of the rotating sleeve disk, and the movement of the movable sleeve ring can drive the connecting part of the wind deflector to deflect clockwise on the supporting frame. When the connecting part deflects clockwise, the telescopic block arranged on the connecting part will drive the connecting rod to move in the direction away from the protrusion. At this time, the stopper on the limit block is separated from the bottom of the protrusion, and the adjusting rack is no longer limited. At this time, the movable frame is movably arranged on the supporting frame; S5: Since the rotating sleeve disk does not continue to drive the rotating rod to move at this time, the torsion spring that has been under stress will drive the installation shaft to rotate and reset the rotating rod. At this time, when the installation shaft rotates, it will drive the installation disk to make the connecting belt drive the adjusting disk to rotate. The rotation of the adjusting disk will cause the inner ratchet to drive the inner ratchet gear to rotate, and then the outer shell drives the adjusting gear ring to move the adjusting rack toward the bottom of the carrier frame. When the moving frame moves, the moving rack on the other side of the moving frame will drive the rotating gear to rotate the one-way shaft. At this time, the rotation of the one-way shaft will drive one of the rotating rollers to rotate, and then the filter belt containing a large amount of dust and impurities will move toward the dust storage chamber. S6: When the filter belt containing dust moves into the dust storage chamber, the air intake fan rotates to restore the air circulation in the air intake chamber to normal, and the baffle portion on the wind baffle plate causes the connecting portion to rotate counterclockwise on the carrier, thereby causing the movable ring to move toward the rotating sleeve, so that the connecting frame can continue to abut against the inner wall of the rotating sleeve, thereby continuing to rotate the rotating rod to drive the torsion spring to store force, so that the filter can continue to be switched when dust accumulates next time; S7: When the torsion spring releases kinetic energy to stop the installation shaft from rotating, the movable frame will move up and reset under the drive of the reset spring. When the movable frame resets, the moving rack drives the rotating gear to rotate. Under the restriction of the one-way shaft, the rotating roller will not drive the filter belt to move and reset. When the adjusting rack contacts the adjusting gear ring, the inner ratchet gear in the outer shell will not drive the inner ratchet pawl to rotate, thereby not affecting the rotation of the installation shaft.

[0013] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, when the rotating rod rotates, the rotating rod will drive the installation shaft to make the torsion spring rotate and expand outward in the annular groove, thereby putting the torsion spring in a stressed state. The block arranged at the end of the torsion spring is initially arranged in the slot in the inner wall of the annular groove. The installation shaft drives the block on the torsion spring to move along the slot in the annular groove. When the torsion spring reaches the critical point, the block on the torsion spring will move to the next slot in the annular groove, thereby avoiding damage caused by overload of the torsion spring. After the torsion spring is in a stressed state and dust is accumulated on the filter screen, the subsequent adjustment device can be conveniently controlled to switch the filter screen by resetting the torsion spring.

[0014] In the present invention, when the movable frame moves, the movable rack on the other side of the movable frame will drive the rotating gear to rotate the one-way shaft. At this time, the rotation of the one-way shaft will drive one of the rotating rollers to rotate, thereby moving the filter belt containing a large amount of dust and impurities toward the dust storage chamber, thereby realizing the movement and switching of the filter belt, so that the filter belt containing no dust is moved between the air inlet chamber and the ventilation chamber to continue to filter dust and impurities in the air, and then quickly switch.

[0015] In the present invention, when the control cabinet shell is ventilated, the movable sleeve ring can drive the rotating rod to rotate when the rotating sleeve disc contacts the connecting frame, and the rotating rod can drive the installation shaft to store force for the torsion spring. When too much dust is accumulated on the filter screen and affects the air circulation in the air inlet chamber, the connecting frame on the movable sleeve ring is separated from the rotating sleeve disc under the drive of the wind deflector. At this time, the kinetic energy of the stressed torsion spring is released, and the rotation directions of the installation shaft and the rotating sleeve disc are opposite. The rotation of the installation shaft can control the adjustment gear ring to move the movable frame downward, and when the movable frame moves downward, the gear can be rotated to make The one-way shaft drives the filter belt to move, and the accumulated dust is moved into the dust storage chamber, while the surface of the filter belt without dust accumulation moves to between the air inlet chamber and the ventilation chamber, and the wind deflector will move and reset, and the connecting frame will contact the inner wall of the rotating sleeve and continue to be connected to each other, so that the torsion spring continues to be stressed. Through the setting of the wind deflector, the torsion spring can store and release energy, which can drive the switching of the filter. During use, the dust on the filter can be effectively handled regularly, without the need for operators to perform regular dust maintenance, thereby improving the service life of the control cabinet shell.

When the drive motor 14 rotates, the main shaft of the drive motor 14 drives the drive disk 24 to rotate, and the driving belt 25 causes the rotating disk 23 to rotate synchronously, thereby causing the rotating rod 21 to rotate. The rotation of the rotating rod 21 drives the rotating sleeve 22 to rotate, and the movable sleeve 34 clamped on the rotating rod 31 is close to the rotating disk 32. At this time, the articulated frame 36 on the movable sleeve 34 drives the two connecting frames 33 on the rotating disk 32 to move on the rotating disk 32 toward the inner wall of the rotating sleeve 22.

[0021] In this embodiment, Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.14 and Fig.15As shown, the wind deflector 4 includes a baffle portion 41 and a connecting portion 42, the baffle portion 41 is located in the air inlet cavity 13, the connecting portion 42 is hingedly arranged on the carrier 17, a correspondingly arranged slide groove 43 is opened on the connecting portion 42, a moving block 44 is correspondingly rotatably arranged on the moving collar 34, and two moving blocks 44 are respectively extended toward the slide groove 43 on the connecting portion 42 and provided with moving rods 45; The baffle portion 41 on the wind baffle 4 is located in the air inlet chamber 13. When the air inlet fan 15 rotates to allow air outside the control cabinet housing 1 to enter the air inlet chamber 13, the air will contact the baffle portion 41. The baffle portion 41 forms resistance to the air, which will cause the connecting portion 42 to deflect counterclockwise on the supporting frame 17. When the connecting portion 42 rotates counterclockwise on the supporting frame 17, the two sliding grooves 43 on the connecting portion 42 will drive the moving rod 45 to move the moving block 44 toward the direction of the rotating sleeve 22. At this time, the moving block 44 will drive the moving sleeve ring 34 to move on the rotating rod 31 toward the direction of the rotating sleeve 22, squeezing the connecting spring 35 to make the connecting frame 33 contact the inner wall of the rotating sleeve 22, so that the rotating sleeve 22 can drive the rotating rod 31 to rotate.

One end of one of the rotating rollers 61 is connected to a unidirectional shaft arranged in one direction. The unidirectional shaft is provided with a rotating gear 63. The rotating gear 63 is meshed with the moving rack 55. When too much dust accumulates on the filter 6 and affects the wind flow in the air inlet chamber 13, the connecting spring 35 arranged between the rotating disk 32 and the movable sleeve ring 34 will push the movable sleeve ring 34 to move in the direction away from the rotating sleeve disk 22. The movement of the movable sleeve ring 34 will pull the hinge frame 36 to separate the connecting frame 33 from the inner wall of the rotating sleeve disk 22, and the movement of the movable sleeve ring 34 can drive the connecting portion 42 of the wind deflector 4 to deflect clockwise on the supporting frame 17. When the connecting portion 42 deflects clockwise, the telescopic block 57 arranged on the connecting portion 42 will drive the connecting rod 59 to move in the direction away from the protrusion 56. At this time, the stopper 512 on the limiting block 510 is separated from the bottom of the protrusion 56, and the adjusting rack 54 is no longer limited. At this time, the movable frame 51 is movably arranged on the supporting frame 17; Since the rotating sleeve 22 does not continue to drive the rotating rod 31 to move at this time, the torsion spring 391 which has been under stress will drive the installation shaft 37 to rotate and reset the rotating rod 31. At this time, when the installation shaft 37 rotates, it will drive the installation disc 515 to make the connecting belt 516 drive the adjusting disc 514 to rotate. The rotation of the adjusting disc 514 will make the inner ratchet pawl 517 drive the inner ratchet gear 519 to rotate, so that the outer shell 518 drives the adjusting gear ring 520 to move the adjusting rack 54 toward the bottom of the carrier 17. When the moving frame 51 moves, the moving rack 55 on the other side of the moving frame 51 will drive the rotating gear 63 to rotate the one-way shaft. At this time, the rotation of the one-way shaft will drive one of the rotating rollers 61 to rotate, thereby moving the filter belt 62 containing a large amount of dust and impurities toward the dust storage chamber 16, thereby realizing the movement and switching of the filter belt 62, so that the filter belt 62 without dust is moved to between the air inlet chamber 13 and the ventilation chamber 11, so that the dust and impurities in the air can continue to be filtered, and then the switching is quickly performed; When the filter belt 62 containing dust moves into the dust storage chamber 16, the air intake fan 15 rotates to restore the air circulation in the air intake chamber 13 to normal, and the baffle portion 41 on the wind baffle plate 4 causes the connecting portion 42 to rotate counterclockwise on the supporting frame 17, thereby causing the movable collar 34 to move toward the rotating sleeve disk 22, so that the connecting frame 33 can continue to abut against the inner wall of the rotating sleeve disk 22, thereby continuing to rotate the rotating rod 31 to drive the torsion spring 391 to store force, so that the filter 6 can continue to be switched when dust accumulates next time; When the torsion spring 391 releases kinetic energy to stop the installation shaft 37 from rotating, the movable frame 51 will move up and reset under the drive of the reset spring 53. When the movable frame 51 is reset, the movable rack 55 drives the rotating gear 63 to rotate. Under the restriction of the one-way shaft, the rotating roller 61 will not drive the filter belt 62 to move and reset. When the adjustment rack 54 contacts the adjustment gear ring 520, the inner ratchet gear 519 in the outer shell 518 will not drive the inner ratchet pawl 517 to rotate, thereby not affecting the rotation of the installation shaft 37. Through this arrangement, when the control cabinet housing 1 is ventilated, the movable sleeve ring 34 can first drive the rotating rod 31 to rotate when the rotating sleeve disk 22 contacts the connecting frame 33, and the rotating rod 31 can drive the mounting shaft 37 to store force in the torsion spring 391. When too much dust accumulates on the filter 6 and affects the air circulation in the air inlet chamber 13, the connecting frame 33 on the movable sleeve ring 34 is separated from the rotating sleeve disk 22 under the drive of the wind deflector 4. At this time, the kinetic energy of the stressed torsion spring 391 is released, and the rotation direction of the mounting shaft 37 is opposite to that of the rotating sleeve disk 22. The rotation of the mounting shaft 37 can control the adjustment gear ring 520 to move the movable frame 51 downward, and when the movable frame 51 moves downward, it can The one-way shaft can drive the filter belt 62 to move by rotating the gear 63, and the accumulated dust can be moved into the dust storage chamber 16, while the surface of the filter belt 62 without dust accumulation can be moved between the air inlet chamber 13 and the ventilation chamber 11, and the wind deflector 4 can be moved to reset, and the connecting frame 33 can contact the inner wall of the rotating sleeve 22 and continue to be connected to each other, so that the torsion spring 391 continues to be stressed. Through the setting of the wind deflector 4, the torsion spring 391 can store and release energy, which can drive the switching of the filter 6. During use, the dust on the filter 6 can be effectively and regularly handled, without the need for operators to perform dust maintenance regularly, thereby improving the service life of the control cabinet housing 1.

[0024] The use method and advantages of the present invention: The use method of the ventilation and dustproof fire pump control cabinet, the working process is as follows: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 , Fig.13 , Fig.14 , Fig.15 As shown: S1: Driven by the driving motor 14, the air inlet fan 15 in the air inlet chamber 13 can rotate, so that the air outside the control cabinet housing 1 enters the air inlet chamber 13 through the ventilation chamber 11, so that the air circulates in the control cabinet housing 1. When the driving motor 14 rotates, the main shaft of the driving motor 14 drives the driving disk 24 to rotate, and the driving belt 25 causes the rotating disk 23 to rotate synchronously, thereby causing the rotating rod 21 to rotate. The rotation of the rotating rod 21 drives the rotating sleeve 22 to rotate, and the movable sleeve 34 clamped on the rotating rod 31 is close to the rotating disk 32. At this time, the articulated frame 36 on the movable sleeve 34 drives the two connecting frames 33 on the rotating disk 32 to move on the rotating disk 32 toward the inner wall of the rotating sleeve 22. When the end face of the connecting frame 33 contacts the inner wall of the rotating sleeve 22, the friction between the two When the rotating sleeve 22 rotates, the movable sleeve 34 can be driven to rotate, and the movable sleeve 34 is clamped on the rotating rod 31, so that the rotating rod 31 can rotate synchronously. When the rotating rod 31 rotates, the rotating rod 31 will drive the installation shaft 37 to make the torsion spring 391 rotate and expand outward in the annular groove 38, so that the torsion spring 391 is in a stressed state. The block 392 set at the end of the torsion spring 391 is initially set in the bayonet 39 in the inner wall of the annular groove 38. The installation shaft 37 drives the block 392 on the torsion spring 391 to move along the bayonet 39 in the annular groove 38. When the torsion spring 391 reaches the critical point, the block 392 on the torsion spring 391 will move to the next bayonet 39 in the annular groove 38, thereby avoiding damage to the torsion spring 391 caused by overload. S2: The baffle portion 41 on the wind baffle plate 4 is located in the air inlet cavity 13. When the air inlet fan 15 rotates to allow air outside the control cabinet housing 1 to enter the air inlet cavity 13, the air will contact the baffle portion 41. The baffle portion 41 forms resistance to the air, which will cause the connecting portion 42 to deflect counterclockwise on the carrier frame 17. When the connecting portion 42 rotates counterclockwise on the carrier frame 17, the two slide grooves 43 on the connecting portion 42 will drive the moving rod 45 to move the moving block 44 toward the direction of the rotating sleeve 22. At this time, the moving block 44 will drive the moving sleeve ring 34 to move on the rotating rod 31 toward the direction of the rotating sleeve 22, squeezing the connecting spring 35 to make the connecting frame 33 contact the inner wall of the rotating sleeve 22, thereby enabling the rotating sleeve 22 to drive the rotating rod 31 to rotate; S3: When the connecting portion 42 of the wind deflector 4 rotates counterclockwise on the carrier 17, the telescopic block 57 on the connecting portion 42 drives the connecting rod 59 to move the limiting block 510 toward the side of the adjusting rack 54 provided with the protrusion 56. At this time, the stopper 512 abuts against the bottom of the protrusion 56, thereby limiting the adjusting rack 54 and restricting the moving frame 51 on the carrier 17. S4: When too much dust accumulates on the filter 6 and affects the wind flow in the air inlet chamber 13, the connecting spring 35 arranged between the rotating disk 32 and the movable sleeve ring 34 will push the movable sleeve ring 34 to move in the direction away from the rotating sleeve disk 22. The movement of the movable sleeve ring 34 will pull the hinge frame 36 to separate the connecting frame 33 from the inner wall of the rotating sleeve disk 22, and the movement of the movable sleeve ring 34 can drive the connecting portion 42 of the wind deflector 4 to deflect clockwise on the supporting frame 17. When the connecting portion 42 deflects clockwise, the telescopic block 57 arranged on the connecting portion 42 will drive the connecting rod 59 to move in the direction away from the protrusion 56. At this time, the stopper 512 on the limit block 510 is separated from the bottom of the protrusion 56, and the adjusting rack 54 is no longer limited. At this time, the movable frame 51 is movably arranged on the supporting frame 17; S5: Since the rotation of the rotating sleeve 22 at this time does not continue to drive the rotating rod 31 to move, the torsion spring 391 which has been under stress will drive the installation shaft 37 to rotate and reset the rotating rod 31. At this time, when the installation shaft 37 rotates, it will drive the installation disc 515 to make the connecting belt 516 drive the adjusting disc 514 to rotate. The rotation of the adjusting disc 514 will make the inner ratchet pawl 517 drive the inner ratchet gear 519 to rotate, and then the outer shell 518 drives the adjusting gear ring 520 to move the adjusting rack 54 toward the bottom of the carrier frame 17. When the moving frame 51 moves, the moving rack 55 on the other side of the moving frame 51 will drive the rotating gear 63 to rotate the one-way shaft. At this time, the rotation of the one-way shaft will drive one of the rotating rollers 61 to rotate, and then the filter belt 62 containing a large amount of dust and impurities will move toward the dust storage chamber 16. S6: When the filter belt 62 containing dust moves into the dust storage chamber 16, the air intake fan 15 rotates to restore the air circulation in the air intake chamber 13 to normal, and the baffle portion 41 on the wind baffle plate 4 causes the connecting portion 42 to rotate counterclockwise on the supporting frame 17, thereby causing the movable collar 34 to move toward the rotating sleeve 22, so that the connecting frame 33 can continue to abut against the inner wall of the rotating sleeve 22, thereby continuing to rotate the rotating rod 31 to drive the torsion spring 391 to store force, so that the filter 6 can continue to be switched when dust accumulates next time; S7: When the torsion spring 391 releases kinetic energy to stop the installation shaft 37 from rotating, the movable frame 51 will move up and reset under the drive of the reset spring 53. When the movable frame 51 is reset, the movable rack 55 drives the rotating gear 63 to rotate. Under the restriction of the one-way shaft, the rotating roller 61 will not drive the filter belt 62 to move and reset. When the adjusting rack 54 contacts the adjusting gear ring 520, the inner ratchet gear 519 in the outer shell 518 will not drive the inner ratchet pawl 517 to rotate, thereby not affecting the rotation of the installation shaft 37.

A method for using a ventilated and dustproof fire pump control cabinet, using the ventilated and dustproof fire pump control cabinet according to any one of claims 1 to 8, characterized in that: The steps include: S1: The drive motor (14) can drive the air inlet fan (15) in the air inlet chamber (13) to rotate, so that the air outside the control cabinet housing (1) enters the air inlet chamber (13) through the ventilation chamber (11), so that the air circulates in the control cabinet housing (1). When the drive motor (14) rotates, the main shaft of the drive motor (14) drives the drive disk (24) to rotate, and the drive belt (25) causes the rotating disk (23) to rotate synchronously, thereby causing the rotating rod (2 1) rotates, the rotating rod (21) rotates, which drives the rotating sleeve (22) to rotate, and the movable sleeve ring (34) clamped on the rotating rod (31) approaches the rotating disk (32). At this time, the hinge frame (36) on the movable sleeve ring (34) drives the two connecting frames (33) on the rotating disk (32) to move on the rotating disk (32) toward the inner wall of the rotating sleeve (22). When the end surface of the connecting frame (33) contacts the inner wall of the rotating sleeve (22), friction between the two is generated. The rotating sleeve (22) is driven by friction transmission, and when the rotating sleeve (22) rotates, the movable sleeve (34) is driven to rotate, and the movable sleeve (34) is clamped on the rotating rod (31), so that the rotating rod (31) can rotate synchronously. When the rotating rod (31) rotates, the rotating rod (31) drives the installation shaft (37) to rotate the torsion spring (391) in the annular groove (38) and expand outward, so that the torsion spring (391) is in a stressed state. The end of the torsion spring (391) is provided with The block (392) is initially arranged in a slot (39) in the inner wall of the annular groove (38), and the mounting shaft (37) drives the block (392) on the torsion spring (391) to move along the slot (39) in the annular groove (38). When the torsion spring (391) reaches a critical point, the block (392) on the torsion spring (391) moves to the next slot (39) in the annular groove (38), thereby preventing the torsion spring (391) from being damaged due to overload; S2: The baffle portion (41) on the wind baffle plate (4) is located in the air inlet cavity (13). When the air inlet fan (15) rotates to allow air outside the control cabinet housing (1) to enter the air inlet cavity (13), the air will contact the baffle portion (41). The baffle portion (41) forms resistance to the air, which causes the connecting portion (42) to deflect counterclockwise on the support frame (17). When the connecting portion (42) rotates counterclockwise on the support frame (17), the two slide grooves (43) on the connecting portion (42) drive the moving rod (45) to move the moving block (44) toward the direction of the rotating sleeve (22). At this time, the moving block (44) drives the moving sleeve ring (34) on the rotating rod (31) to move toward the direction of the rotating sleeve (22), compressing the connecting spring (35) to make the connecting frame (33) contact the inner wall of the rotating sleeve (22), thereby enabling the rotating sleeve (22) to drive the rotating rod (31) to rotate; S3: When the connecting portion (42) of the wind deflector (4) rotates counterclockwise on the carrier (17), the telescopic block (57) on the connecting portion (42) drives the connecting rod (59) to move the limiting block (510) toward the side of the adjusting rack (54) provided with the protrusion (56), and at this time, the stop block (512) abuts against the bottom of the protrusion (56), thereby limiting the adjusting rack (54) and restricting the movable frame (51) on the carrier (17); S4: When too much dust accumulates on the filter (6) and affects the wind flow in the air inlet chamber (13), the connecting spring (35) disposed between the rotating disk (32) and the movable sleeve (34) will push the movable sleeve (34) to move in a direction away from the rotating sleeve (22). The movement of the movable sleeve (34) will pull the hinge frame (36) to separate the connecting frame (33) from the inner wall of the rotating sleeve (22), and the movement of the movable sleeve (34) can drive the wind deflector ( 4) is deflected clockwise on the carrier (17). When the connecting portion (42) is deflected clockwise, the telescopic block (57) arranged on the connecting portion (42) drives the connecting rod (59) to move in a direction away from the protrusion (56). At this time, the stopper (512) on the limit block (510) is separated from the bottom of the protrusion (56) and the adjustment rack (54) is no longer limited. At this time, the movable frame (51) is movably arranged on the carrier (17); S5: Since the rotating sleeve (22) does not continue to drive the rotating rod (31) to move when it rotates at this time, the torsion spring (391) which is always in a stressed state will drive the installation shaft (37) to rotate and reset the rotating rod (31). At this time, when the installation shaft (37) rotates, it will drive the installation plate (515) to make the connecting belt (516) drive the adjustment plate (514) to rotate. The rotation of the adjustment plate (514) will cause the inner ratchet (517) to drive the inner ratchet gear (519) to rotate, thereby causing the outer shell (518) to drive the adjustment gear ring (520) to move the adjustment rack (54) toward the bottom of the carrier frame (17). When the moving frame (51) moves, the moving rack (55) on the other side of the moving frame (51) will drive the rotating gear (63) to rotate the one-way shaft. At this time, the rotation of the one-way shaft will drive one of the rotating rollers (61) to rotate, thereby moving the filter belt (62) containing a large amount of dust and impurities toward the dust storage chamber (16); S6: When the filter belt (62) containing dust moves into the dust storage chamber (16), the air inlet fan (15) rotates to restore the air circulation in the air inlet chamber (13) to normal, and the baffle portion (41) on the wind baffle plate (4) causes the connecting portion (42) to rotate counterclockwise on the support frame (17), thereby causing the movable ring (34) to move in the direction of the rotating sleeve disk (22), so that the connecting frame (33) can continue to abut against the inner wall of the rotating sleeve disk (22), thereby continuing to rotate the rotating rod (31) to drive the torsion spring (391) to store force, so that the filter (6) can continue to be switched when dust accumulates next time; S7: When the torsion spring (391) releases kinetic energy to stop the installation shaft (37) from rotating, the movable frame (51) moves upward and resets under the drive of the reset spring (53). When the movable frame (51) resets, the movable rack (55) drives the rotating gear (63) to rotate. Under the restriction of the one-way shaft, the rotating roller (61) will not drive the filter belt (62) to move and reset. When the adjustment rack (54) contacts the adjustment gear ring (520), the inner ratchet gear (519) in the outer shell (518) will not drive the inner ratchet pawl (517) to rotate, thereby not affecting the rotation of the installation shaft (37).
