Based on this design, when the device is started, the first driving part drives the first plugging plate 140 to move towards the ventilation position at the first plugging position, and the first driving part synchronously drives the second plugging plate 180 to move towards the second plugging position at the dust discharging position, during this process, the communication port 130 on the first plugging plate 140 is gradually opened, the dust discharging port 170 is gradually closed, at this time, a part of air entering the secondary filter chamber 112 flows towards the communication port 130, and the other part flows towards the dust discharging port 170, so as to perform a dust removing operation, and correspondingly, when the device is stopped, the first driving part drives the first plugging plate 140 to move towards the first plugging position at the ventilation position, and the first driving part synchronously drives the second plugging plate 180 to move towards the dust discharging position at the second plugging position, during this process, the dust removing operation is also performed, and it can be understood that each time when the device or the closing device is started, the dust removing operation is performed, and when the device is started, the third driving part drives the filter cylinder 310 to rotate, so that the filter cylinder 310 gradually moves towards the dust discharging port 170 at one side part of the air inlet 160.
It should be noted that the dust removal operation is performed every time the device is started or shut down, so that the dust removal effect is prevented from being affected due to too much dust adhering to the filter cartridge 310.
In this embodiment, the communication port 130 is fan-shaped, the first plugging plate 140 is adapted to the communication port 130 and is tightly attached to the upper surface of the partition board 120, the first driving portion includes a rotation shaft 400, the rotation shaft 400 penetrates through the partition board 120 and is rotatably assembled in the center of the partition board 120, the first plugging plate 140 is fixedly connected with the outer side wall of the rotation shaft 400, a motor 410 is fixed on the partition board 120 at the bottom end of the rotation shaft 400, and the motor 410 is in transmission connection with the rotation shaft 400. The motor 410 can drive the rotation shaft 400 to rotate, so that the first plugging plate 140 fixed with the rotation shaft 400 moves, and the first plugging plate 140 is driven to move at the first plugging position and the ventilation position.
In this embodiment, the sealing plate 320 has a through groove 321 formed in the middle, the third driving portion includes a one-way bearing 500 fixedly mounted in the through groove 321, the top end of the rotating shaft 400 passes through the through groove 321, and the inner side of the one-way bearing 500 is fixedly connected with the rotating shaft 400. When the rotation shaft 400 rotates forward, the rotation shaft 400 can drive the first plugging plate 140 to move towards the ventilation position at the first plugging position, at this time, the one-way bearing 500 is in a locking state, the rotation shaft 400 is fixedly connected with the sealing plate 320, so that the rotation shaft 400 rotates to drive the sealing plate 320 to rotate together, and further drive the filter cartridge 310 to rotate, so as to realize rotation control of the filter cartridge 310, when the rotation shaft 400 rotates reversely, the rotation shaft 400 can drive the first plugging plate 140 to move towards the first plugging position at the ventilation position, at this time, the one-way bearing 500 is in an active state, the rotation shaft 400 is in rotational connection with the sealing plate 320, and rotation of the rotation shaft 400 can not drive the filter cartridge 310 to rotate, it can be understood that the forward rotation of the rotation shaft 400 drives the first plugging plate 140 to move towards the ventilation position at the first plugging position at a certain angle, and the reverse rotation of the rotation shaft 400 drives the first plugging plate 140 to move towards the first plugging position, so that the filter cartridge 310 remains stationary.

Based on the above design, the brush 700 may clean dust from the outer wall of the filter cartridge 310 during the movement of the second blocking plate 180.
In this embodiment, the sterilization module 800 is a high-flux pulsed xenon lamp, and the pulsed xenon lamp is a novel cold sterilization technology, which instantaneously releases the electric energy accumulated in the ultra-large capacity capacitor, and generates pulsed strong light with the energy up to 2J/c square meter for only 10-100 ms continuously through the high-purity xenon gas in the high-voltage ionization lamp tube, so as to effectively destroy various pathogens, thereby achieving the sterilization and disinfection effects.
Specifically, the high-flux pulse xenon lamp comprises a control unit, a power unit, a trigger unit and a processing unit. The power unit provides high-voltage high-current energy for the xenon lamp and triggers xenon ionization; after the energy storage capacitor is charged for a relatively long time (hundreds ms), discharging is carried out in an extremely short time (tens to hundreds mu s), the discharging voltage causes the xenon avalanche ionization in the lamp tube, the xenon converts and releases the charged energy in the form of high-intensity light radiation, and the discharging process is a light pulse; the control module can enable the pulse xenon lamp to start and stop at any time, and the reaction is rapid, compared with the ultraviolet lamp which needs to be preheated before being started, the requirement of being used at any time cannot be met, and in special occasions such as the process of packaging protein medicines, the protein can be denatured due to ultraviolet rays, so that the products need to be accurately controlled when being sterilized, the sterilization is immediately carried out when the parts needing to be sterilized are entered, and the parts which cannot be irradiated by the ultraviolet rays need to be immediately stopped after the parts which cannot be irradiated by the ultraviolet rays enter.
In this embodiment, a contact switch (not shown) for controlling the air extraction device is disposed on the partition 120, when the first blocking plate 140 is at the first blocking position, the first blocking plate 140 just contacts with the contact switch, at this time, the air extraction device stops working, and when the first blocking plate 140 is not moved to the first blocking position, the first blocking plate 140 does not contact with the contact switch, at this time, the air extraction device is started. Based on the above design, when this device starts, after first shutoff board 140 breaks away from first shutoff position once, updraft ventilator just starts, and this in-process, updraft ventilator leading-in air current can carry out dust removal operation, and when this device stopped, first shutoff board 140 is in ventilation position orientation first shutoff position removal in-process, updraft ventilator has not stopped yet, and updraft ventilator leading-in air current also can carry out dust removal operation this moment, and when first shutoff board 140 was in first shutoff position, first shutoff board 140 just contacted with contact switch, at this moment, updraft ventilator stop work. It should be noted that the rotation speed of the rotation shaft 400 is slow in this process.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
