[0047] The jet structure 7 can jet during the dust cleaning process to further clean the fan blades 404 .

[0048] The working principle of the present invention is as follows:

[0049] When the disinfection cabinet is exhausted in the drying mode, the driving source 506 is turned on to drive the rotating short shaft 507 to rotate. The rotating short shaft 507 will drive the first rotating tooth 508 to rotate during the rotation process. The first rotating tooth 508 is engaged with the second rotating tooth 509 and the second rotating tooth 509 is driven to rotate during the rotation process. The rotating tube 504 will drive the fixed frame 510 to rotate during the rotation process. The fixed frame 510 is connected to the external power supply through the embedded second conductive ring 513. When the outer wall of the second conductive ring 513 is touched, the external power supply will supply power to the first electromagnet 607 to generate a strong magnet, so that the first electromagnet 607 will be adsorbed on the outer peripheral surface of the fixed frame 510 and remain fastened. When the rotating tube 504 is driven to drive the fixed frame 510 to rotate, the fixed frame 510 will drive the first electromagnet 607 and the fan blades 404 to rotate. The centrifugal force generated by the rotating fan blades 404 sucks air from the air inlet end 402, and then moves outward along the fan blades 404, and finally discharged through the exhaust pipe 406, so as to exhaust air;

[0050] It should be noted that the housing 401 and the fixing plate 503 are respectively fixed to the inner bottom end of the disinfection cabinet 1 , and the exhaust pipe 406 will exhaust the air to the outside of the disinfection cabinet 1 during exhaust.

[0051] When cleaning the dust accumulated on the fan blades 404 for a long time, the installed differential pressure sensor 403 detects the change of air pressure at the air outlet (the differential pressure sensor 403 is calibrated before the detection is required, and the air pressure standard range of the maximum power generated by the fan blades 404 without dust is used as the standard, and the fan blades can be subsequently cleaned when it is lower than this range). When the differential pressure sensor 403 detects that the air pressure at the air outlet is reduced due to the accumulation of dust on the fan blades 404, the differential pressure sensor 403 will be connected to the input end of the controller (not shown in the figure), and the controller transmits the signal to the linear drive 601, and the linear drive 601 is directly connected to the linear drive 601. After receiving the signal, the linear driver 601 drives the sliding connection block 603 to drive the circular chuck 604 to move in the direction close to the fixed plate 503. When the circular chuck 604 moves, it drives the first electromagnet 607 to detach from the outer peripheral surface of the fixed frame 510 through the connecting ring 605 and the connecting support rod 606. At the same time, the circular chuck 604 also drives the connecting ring 611 to move through the retractable barrel 619 and the telescopic barrel 618. When it moves to a position close to the fixed plate 503, the connecting ring 611 drives the second electromagnet 610 to be adsorbed on the outer peripheral surface of the iron ring 511, and the first conductive ring 512 embedded in the iron ring 511 is The external power supply energizes the second electromagnet 610 to generate a strong magnet, so that the second electromagnet 610 is adsorbed on the outer peripheral surface of the iron ring 511 for fixation, and the linear drive 601 will continue to drive the circular chuck 604 to move in the direction of the fixed plate 503. At this time, the linear drive 601 will drive the retractable barrel 619 to slide on the outer wall of the telescopic barrel 618 and compress the spring 620. As the linear drive 601 continues to drive the circular chuck 604 to move in the direction of the fixed plate 503, the sliding box 608 fixed to the circular chuck 604 will drive the connecting bracket 614 to slide on the inner wall of the sliding box 608 through the connecting sliding member 615. When the connecting bracket 614 slides in the middle, the multiple connecting brackets 614 will slide outward and spread out along the axis of the circular chuck 604, so that the connecting bracket 614 and the rotating bracket 613 will simultaneously change from a close state to a spread out state. When the connecting bracket 614 slides and spreads out through the sliding member 615 on the inner wall of the sliding box 608, it will also drive the sponge scraper 617 and the fixed bracket 616 to move together. The fixed bracket 616 will contact the windward surface of the fan blade 404 during the movement and clean the dust accumulated on the windward surface of the fan blade 404. In this process, the retractable barrel 619 and the telescopic barrel 618 will be completely merged and overlapped together.

[0052] It should be noted that when the sponge scraper 617 contacts the windward surface of the fan blade 404, the fan blade 404 has a certain curvature, and the sponge scraper 617 has a certain elasticity. Therefore, when the sponge scraper 617 cleans the fan blade 404, the fan blade 404 changes irregularly due to the curvature of the curvature and the distance between the connecting bracket 614. The sponge scraper 617 can also be cleaned by the set width and elasticity and fits the windward surface of the fan blade 404.

[0053] When the dust is cleaned by centrifugal force, when the disinfection cabinet is in drying mode, the dried water vapor will be discharged outward along with the air by the fan structure 4, and part of the water vapor will adhere to the fan blade 404 along with the dust. Although the dust on the windward side of the fan blade 404 is cleaned by the fixed bracket 616, the dust may adhere to the fixed bracket 616 through the moisture containing water vapor. At this time, the rotating tube 504 is driven to rotate in the opposite direction by turning on the driving source 506. The rotating tube 504 will drive the iron ring 511 to rotate during the rotation process, and the iron ring 511 is adsorbed on the outer periphery of the iron ring 511 by powering on. The second electromagnet 610 on the surface will rotate together, and the second electromagnet 610 will also drive the connecting ring 611, the circular chuck 604 and the fan blade 404 to rotate together during the rotation. The centrifugal force generated by the rotation will cause the dust attached to the fixed bracket 616 to fall off, thereby completing the cleaning of the fixed bracket 616, avoiding the fixed bracket 616 from being dirty and failing to achieve the effect of cleaning the defects, and the dust detached from the fixed bracket 616 will be uniformly collected by the collection cover 501, and the dust in the collection cover 501 can be cleaned later by opening the sliding plate 502;

[0054] When cleaning is performed by jetting, the rotating tube 504 rotates in the opposite direction to drive the connecting ring 611, the circular chuck 604 and the fan blade 404 to rotate, the rotating tube 504 will drive the ventilation tube 702 to rotate through the one-way bearing 701, and the ventilation tube 702 will drive the gas injection cylinder 705 to rotate during the rotation process, and the gas injection cylinder 705 will drive the sliding joint 711 to slide through the slide groove during the rotation process (the rotation contact point of the slide groove is at a different distance from the side of the gas injection cylinder 705, so the sliding joint 711 will slide back and forth when sliding inside the slide groove), and the sliding joint 711 will drive the connecting frame 708 and the slider 710 to reciprocate on the outer circumference of the gas injection cylinder 705 during the sliding process. 08 During the reciprocating motion, the piston 706 will be driven by the connecting shaft 707 to slide back and forth on the inner wall of the gas injection cylinder 705. During each reciprocating sliding process of the piston 706, the air will re-enter the gas injection cylinder 705 from the air inlet hole. As the piston 706 squeezes the gas injection cylinder 705, the air inside will be injected into the airbag 704 through the slot 703. After the airbag 704 is expanded for a certain period of time after being injected with air, the air pressure inside will break through the opening pressure set by the pressure valve 712 and will be injected into the rotating tube 504. The injected air will finally be ejected through the jet port 713 to the driven fan blade 404 and the fixed bracket 616 at the jet port 713 for the final cleaning step.

[0055] During the process of re-exhausting air, the circular chuck 604 is driven by the second electromagnet 610 to move back to the inner wall of one side of the outer shell 401 and drive the first electromagnet 607 to contact the outer peripheral surface of the fixed frame 510 again for adsorption, so as to drive the fan blades 404 to rotate again, so that the fan blades 404 can be driven to rotate by being adsorbed together with the fixed frame 510 by the first electromagnet 607.
