[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-4This utility model provides an embodiment of a protective and isolating air purification device, including a first purification cylinder 1, a second purification cylinder 2, an air exchange mechanism 5, a first filter mechanism 6, a second filter mechanism 8, and a HEPA filter 9. The second purification cylinder 2 is located at the rear end of the first purification cylinder 1. The first purification cylinder 1 has a first purification chamber inside, and the first purification chamber has an air exchange mechanism 5 for air exchange. The air exchange mechanism 5 includes a rotating shaft 13. The first filter mechanism 6 for adsorbing harmful substances is located behind the air exchange mechanism 5. The second purification cylinder 2 has a second purification chamber inside, and the front end of the second purification chamber has a second filter mechanism 8 that cooperates with the first filter mechanism 6. The HEPA filter 9 for isolating microorganisms in the air is located behind the second filter mechanism 8.

[0022] Please see Figures 1-2 In this embodiment, the rotating shaft 13 is located at the front center of the fixed frame 12. Three sets of fan blades 14 are arranged around the outer end of the rotating shaft 13. A drive motor 15 is located at the rear center of the fixed frame 12. A transmission shaft is provided between the rotating shaft 13 and the drive motor 15. One end of the transmission shaft is connected to the rotating shaft 13, and the other end passes through the center of the fixed frame 12 and is connected to the drive motor 15. Through the combination of the rotating shaft 13 and the fan blades 14, during operation, the drive motor 15 drives the transmission shaft to rotate the rotating shaft 13. 3 drives the three sets of fan blades 14 to rotate. When the three sets of fan blades 14 rotate, they generate negative pressure, which promotes the flow of outside air into the room and plays the role of ventilation in the clean room. The rear end of the first purification cylinder 1 is provided with a snap-fit ​​ring block 11, and the front end of the first purification cylinder 1 is provided with a snap-fit ​​ring groove 7 corresponding to the snap-fit ​​ring block 11. By combining the snap-fit ​​ring block with the snap-fit ​​ring groove 7, when the purification device is installed at the ventilation opening of the clean room, the first purification cylinder 1 and the second purification cylinder 2 can be snapped together as a whole by the snap-fit ​​ring groove 7 and the snap-fit ​​ring block 11.

[0023] Please see Figures 2-3In this embodiment, the first filtration mechanism 6 includes a primary fixing ring 17, a secondary fixing ring 18 at the center of the primary fixing ring 17, and a motor receiving groove 19 at the center of the secondary fixing ring 18 for accommodating the drive motor 15. Multiple sets of first activated carbon adsorption plates 20 are arranged around the primary fixing ring 17 and the secondary fixing ring 18. The inner wall of the first purification chamber has a first fixing ring groove 16 corresponding to the primary fixing ring 17. Through the combination of multiple sets of first activated carbon adsorption plates 20 and multiple sets of second activated carbon adsorption plates 26, air passes through the first activated carbon adsorption plates 20 and the second... When the activated carbon adsorption plate 26 is in use, the trace pollutants remaining in the air are adsorbed by the pores on the surface of the first activated carbon adsorption plate 20 and the second activated carbon adsorption plate 26. The ends of the first purification cylinder 1 and the second purification cylinder 2 that are far apart are both provided with a cover mesh groove 3. The inside of the two sets of cover mesh grooves 3 are respectively installed with a first protective cover mesh 4 and a second protective cover mesh 10. By combining the first protective cover mesh 4 and the second protective cover mesh 10, the first protective function is to protect the staff and prevent the user from accidentally touching the rotating fan blades 14. At the same time, it prevents larger floating objects in the air from entering the interior of the purification device and damaging the purification device.

[0024] Please see Figures 3-4 In this embodiment, a first annular fixing frame 22 is fitted around the outer end of the HEPA filter 9, and a second fixing ring groove 21 corresponding to the first annular fixing frame 22 is opened on the inner wall of the second purification chamber. Multiple sets of filter holes 23 are evenly opened on the surface of the HEPA filter 9. By combining the HEPA filter 9 with the multiple sets of filter holes 23 on the surface, when outside air enters the purification device, the user can select different levels of HEPA filter 9 according to their own needs. The H13 grade HEPA filter 9 can effectively filter out more than 99.97% of bacteria and viruses in the air, providing efficient protection and isolation. The second filtration mechanism 8 includes a second annular fixing frame 25, and a negative ion generator is provided in the center of the inner part of the second annular fixing frame 25. The generator 27 (model HO5-N202MS-I) is surrounded by multiple sets of second activated carbon adsorption plates 26 between the second annular fixing frame 25 and the negative ion generator 27. The interior of the second purification chamber is provided with a third fixing ring groove 24 corresponding to the second annular fixing frame 25. By combining the negative ion generator 27, the second activated carbon adsorption plates 26 and the first activated carbon adsorption plates 20, when air enters the second filter mechanism 8 and the first filter mechanism 6, the negative ion generator 27 can actively release negative ions, which destroy the cell structure of bacteria and viruses adsorbed by the second activated carbon adsorption plates 26 and the first activated carbon adsorption plates 20, making them inactive and preventing them from multiplying in the purification device.

[0025] During operation, the user snaps the first purification cylinder 1 and the second purification cylinder 2 together with the snap-fit ​​ring block 11 through the snap-fit ​​ring groove 7. Then, the purification device is installed at the ventilation opening of the clean room. Next, the drive motor 15 drives the transmission shaft to rotate the rotating shaft 13. The rotating shaft 13 drives the three sets of fan blades 14 to rotate. When the three sets of fan blades 14 rotate, they generate negative pressure, which promotes the flow of outside air into the room and plays the role of ventilation in the clean room.

[0026] When outside air enters the purification device, users can select different levels of HEPA filter 9 according to their needs. The H13 grade HEPA filter 9 can effectively filter out more than 99.97% of bacteria and viruses in the air, providing highly efficient protection and isolation.

[0027] When air passes through the first filter mechanism 6 and the second filter mechanism 8, the trace pollutants remaining in the air are adsorbed by the pores on the surface of the first activated carbon adsorption plate 20 and the second activated carbon adsorption plate 26. At the same time, the negative ion generator 27 can actively release negative ions, destroy the cell structure of the adsorbed bacteria and viruses, make them lose their activity and prevent them from multiplying in the purification device, effectively protecting and isolating microorganisms and pollutants in the cleanroom indoor and outdoor air.

[0028] Through the above steps, this application combines the first purification cylinder 1, the second purification cylinder 2, the ventilation mechanism 5, the first filtration mechanism 6, the second filtration mechanism 8, and the HEPA filter 9. During operation, the staff combines the first purification cylinder 1 and the second purification cylinder 2 and installs them at the ventilation opening of the cleanroom. First, the ventilation mechanism 5 draws outside air into the cleanroom for ventilation. Then, the HEPA filter 9 filters out particles larger than 0.3 micrometers in the air. Next, the first filtration mechanism 6 and the second filtration mechanism 8, combined, adsorb any remaining trace pollutants in the air. Finally, the second filtration mechanism 8 releases negative ions to destroy the cell structure of the adsorbed bacteria and viruses, rendering them inactive and preventing their reproduction within the purification device. This effectively protects and isolates microorganisms and pollutants from the air inside and outside the cleanroom.
