Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 , Figure 2 , Figure 3In this embodiment of the invention, a plasma disinfection and sterilization air purification device includes a purification chamber 1. The side wall of the purification chamber 1 is provided with an inspection cover 21 and a controller. Inside the purification chamber 1, an electrostatic adsorption module 4, a plasma generation module 5, and an ozone removal module 6 are sequentially arranged. An air inlet channel 2 and an air outlet channel 3 are respectively provided at both ends of the purification chamber 1. A filter cartridge 7 is rotatably mounted inside one end of the air inlet channel 2 via a first connecting shaft 9. The filter cartridge 7 at one end of the air inlet channel 2 removes large particulate impurities from the gas. Subsequently, the gas undergoes electrostatic adsorption, plasma dust removal, and ozone removal through the electrostatic adsorption module 4, the plasma generation module 5, and the ozone removal module 6. In addition, the purified gas is discharged through the exhaust channel 3. One end of the first connecting shaft 9 is connected to the first motor 11 through the first gear set 10. The lower end of the intake channel 2 is also provided with a storage box 8. The storage box 8 is provided with a cleaning scraper 17 through an elastic mechanism. By setting the filter mechanism into a roller shape, the filter cylinder 7 is driven to rotate at a uniform speed by the first motor 11 and the first gear set 10. The cleaning scraper 17 set vertically on the filter cylinder 7 can be used to scrape and clean the outside of the filter cylinder 7, preventing the filter cylinder 7 from being blocked and affecting the dust removal efficiency. Moreover, the cleaning efficiency is high and the cleaning operation is convenient and quick. The storage box 8 is used to store the dust scraped off by the cleaning scraper.

[0023] like Figure 1 and Figure 2 As shown, in order to improve the sealing performance of the sliding connection between the outside of the filter cylinder 7 and the air inlet of the air inlet channel 2, the filter cylinder 7 is also designed as a metal hollow mesh cylinder, and the diameter of the filter cylinder 7 is smaller than the width of the air inlet of the air inlet channel 2. The air inlet of the air inlet channel 2 is rectangular, and the inner wall of the air inlet is provided with a rubber sealing layer, which facilitates the improvement of the sealing performance of the sliding connection between the outside of the filter cylinder 7 and the air inlet of the air inlet channel 2, and facilitates the gas to enter the purification chamber 1 for purification through the filter cylinder 7.

[0024] like Figure 1 and Figure 2 As shown, in order to facilitate the discharge of dust collected in the storage box 8, a connecting arm 13 is provided on the outer side of the lower end of the air intake channel 2. One end of the connecting arm 13 is rotatably connected to the outer wall of the storage box 8 through a second connecting shaft 12. One end of the second connecting shaft 12 is connected to a second motor 15 through a second gear set 14. The second gear set 14 is a reduction gear set, and the second motor 15 is fixedly installed on the outer wall of the connecting arm 13 through a mounting base. This allows the storage box 8 to be rotated and adjusted by the second motor 15 and the second gear set 14. When the opening of the storage box 8 faces downwards, it is convenient to discharge the dust collected in the storage box 8, making dust discharge convenient and quick.

[0025] like Figure 1 and Figure 3As shown, in order to improve the efficiency of cleaning the exterior of the filter cartridge 7, the elastic mechanism includes a limiting groove 18 provided on the inner wall of the storage box 8. Inside the limiting groove 18, a lifting plate 16 is elastically slidably provided via a guide rod 19 and a spring 20. A cleaning scraper 17 is vertically installed on one side of the lifting plate 16. A flexible dust scraping layer 22 is provided on one side of the cleaning scraper 17. The flexible dust scraping layer 22 is a cleaning bristle structure, which allows the cleaning scraper 17 to be elastically installed in the storage box 8 using the guide rod 19, spring 20 and lifting plate 16, and can perform flexible dust scraping cleaning on the exterior of the filter cartridge 7, which facilitates the improvement of cleaning efficiency and at the same time prevents the cleaning scraper 17 from damaging the filter cartridge 7.

[0026] The working principle and usage process of this utility model are as follows: In use, the gas to be purified enters the purification chamber 1 through the air inlet channel 2. Large particulate impurities in the gas are removed by the filter cylinder 7 at one end of the air inlet channel 2. Then, the gas undergoes electrostatic adsorption, plasma dust removal, and ozone removal through the electrostatic adsorption module 4, the plasma generation module 5, and the ozone removal module 6. The purified gas is discharged through the air outlet channel 3. Moreover, by setting the filter mechanism in the shape of a drum, the filter cylinder 7 is driven to rotate at a uniform speed by the first motor 11 and the first gear set 10. The cleaning scraper 17 set vertically on the filter cylinder 7 can be used to scrape and clean the outside of the filter cylinder 7, preventing the filter cylinder 7 from clogging and affecting the dust removal efficiency. The cleaning efficiency is high, and the cleaning operation is convenient and quick.
