After the movable cover 2 rotates, it will block the two sets of air outlet grilles 13 on the top of the casing 1 and the air inlet grilles 10 at both ends of the casing 1. Completely blocking the air inlet grilles 10 and air outlet grilles 13 can effectively prevent dust from entering. When working again, the first drive motor 5 will be activated at the same time, which will also drive the movable cover 2 to rotate 90°, so that the air inlet grilles 10 and air outlet grilles 13 are open and the air can be purified normally, thus preventing dust from entering the air outlet.

[0031] An air intake grille 10 is movably hinged to the bottom of the groove 9. A fixed mesh plate 16 is fixedly connected to one end of the air intake grille 10. A filter screen 12 is movably connected to the inside of the air intake grille 10. Movable cavities 15 are provided at both ends inside the housing 1. A spring 14 is fixedly connected to the top of the movable cavity 15. A movable block 11 is fixedly connected to the bottom end of the spring 14. A paddle 7 is fixedly connected to one end of the movable block 11. Movable slots 6 are opened at both ends of the housing 1.

[0038] Specifically, such as Figure 1 , Figure 2 and Figure 6 As shown, when the air purifier is turned on, the second drive motor 20 installed inside the base 8 will be started at the same time. After the second drive motor 20 is started, it drives the drive gear 21 to rotate. The drive gear 21 then drives the top casing 1 to rotate slowly through the transmission gear plate 19. While the casing 1 is rotating, it can drive the air intake grille 10 to rotate continuously, thereby absorbing air from different areas in the space, thus enhancing the purification effect and realizing the ability to absorb air from multiple angles for purification.

[0039] Working Principle: When this utility model is in use, after the air purifier is turned on, the second drive motor 20 installed inside the base 8 will be started simultaneously. After the second drive motor 20 starts, it drives the drive gear 21 to rotate. The drive gear 21 then drives the top casing 1 to rotate slowly through the transmission gear plate 19. While the casing 1 is rotating, it can drive the air intake grille 10 to rotate continuously, thereby absorbing air from different areas of the space and enhancing the purification effect. When the air purifier is turned off after working, it will start the first drive motor 5. The first drive motor 5 drives the connecting plate 4 and the movable cover 2 to rotate 90° according to the set program. After the movable cover 2 rotates, it will block the two sets of air outlet grilles 13 on the top of the casing 1 and the air intake grilles 10 at both ends of the casing 1, thus blocking the air intake grilles 10 and the air outlet grilles. The complete shielding of 13 can effectively prevent dust from entering. When working again, the first drive motor 5 will be started at the same time, which will also drive the movable cover 2 to rotate 90°, so that the air intake grille 10 and the air outlet grille 13 can be opened to purify the air normally. After the air purifier has been working for a long time, the lever 7 can be pulled to lift the movable block 11. The movable block 11 will drive the positioning insert 17 to disengage from the inside of the air intake grille 10, and the air intake grille 10 can be pulled to open it so that the filter screen 12 can be pulled out for cleaning. After cleaning, the filter screen 12 is inserted between the air intake grille 10 and the fixed mesh plate 16, and then the air intake grille 10 is closed. Finally, the spring 14 can push the positioning insert 17 out through the movable block 11 so that it is inserted between the air intake grille 10 and the fixed mesh plate 16, thereby positioning the air intake grille 10.
