[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The air purifier and its mounting shell, through the purifier lower shell, purifier base, display body, purifier upper shell, filter element body, positioning column, mounting ring, elastic cylinder, spring body, telescopic cylinder, first moving plate, second moving plate, connecting plate, first pressing block, first rack plate, rotating column, first gear, stabilizing frame, second gear, moving rack plate and moving rack plate, before installing the purifier lower shell and purifier upper shell, first install the filter element body to the surface of the purifier lower shell and purifier base, and at the same time, the lower end of the filter element body is provided with a groove adapted to the positioning column, so that the filter element body can be positioned and installed by the positioning column, and then the purifier upper shell is aligned with the purifier lower shell and moves downward, and then the purifier upper shell will The first gear is engaged with the first gear and the second gear is engaged with the first gear. The first moving plate will drive the first pressing block to descend, and the first pressing block will press the filter element body to move downward. At this time, the filter element body is on the surface of the positioning column, and then when the filter element body continues to move downward, this will cause the filter element body to move downward. The groove at the bottom of the filter element body is adapted to the elastic tube, and the elastic tube will be pressed downward by the filter element body. At this time, the spring body begins to compress, and the telescopic tube limits the movement of the spring body, so that the entire filter element body will also be limited and fixed. The design moves the upper shell of the purifier downward. First, it can ensure the stability of the installation between the upper shell of the purifier and the lower shell of the purifier, and ensure that the first moving plate can be magnetically fixed to the iron plate on the inner wall of the lower shell of the purifier. At the same time, the stability of the first moving plate is enhanced by the contact frame contacting the first moving plate. Then, the upper and left surfaces of the filter element body are limited by the movement of the contact ring and the first pressing block, thereby solving the problem that the purifier shell cannot be installed and locked at one time in the past, reflecting the functionality of the design.

[0019] 2. The air purifier and its mounting shell are provided with a second moving plate, a second pressing block, a first rotating gear, a second rotating gear, a second rack plate, a limiting plate, a sliding block, a worm, a worm wheel, a motor body, a rotating shell, an iron block, a magnet body, a control button and a magnet frame. When the first moving plate moves downward, the second moving plate will also move downward. Before the upper shell of the purifier moves downward, the rotating shell will first be rotated until the iron block and the magnet body are magnetically attached. Then, when the second moving plate descends, the back side of the second moving plate is meshed with the second rotating gear, and then the second rotating gear will also rotate counterclockwise. Subsequently, the second rotating gear drives the first rotating gear to rotate, and then the first rotating gear will rotate. The second rack plate and the limit plate are driven to move toward the back side, and the sliding block is slidably installed inside the rotating shell, so that the second rack plate and the limit plate can slide stably. When the second moving plate stops moving, the back side of the limit plate will contact the back side of the inner wall of the lower shell of the purifier. Therefore, the lower shell of the purifier and the rotating shell can be limited and locked through the limit plate. At the same time, the second pressing block on the left side of the movable rack plate will also be pressed on the upper surface of the filter element body. The filter element body can be stably pressed and fixed through the cooperation between the second pressing block and the first pressing block. The overall filter element body has good installation stability. When the filter element body needs to be removed later, the first method can directly take the purifier upper shell from the top surface of the purifier lower shell. The filter element body is moved in an upward direction, so that the first moving plate and the second moving plate will also move upward, so that the abutment frame and the abutment ring will return to their original positions, so that the first moving plate and the filter element body are both released from the limit lock, and when the limit is released on the top surface of the filter element body, the spring body is not pressed by the filter element body, and the spring body begins to return to its original position and can push the filter element body upward, so that the upper shell of the purifier can be quickly removed from the top surface of the lower shell of the purifier. The second method is to press the control button, and then the motor body starts, the motor body drives the worm wheel to rotate, and then the worm wheel drives the worm to rotate, and then the worm drives the first rotating gear and the second rotating gear to rotate, and the second rotating gear starts to rotate clockwise, and the second moving gear starts to rotate clockwise. The plate will move upward, and the second rack plate and the limit plate will also move forward, so that the limit between the rotating shell and the lower shell of the purifier is released. At the same time, the second moving plate will also drive the upper shell of the purifier slightly upward. At this time, the top surface of the filter element body also contacts the limit, and then the rotating shell can be rotated, so that the filter element body inside the lower shell of the purifier can be taken out and replaced. After taking it out, the rotating shell is rotated again to re-install the iron block and the magnet body by magnetic attraction. This design can press and fix the top surface of the filter element body simultaneously to ensure the stability of the filter element body during installation and use. At the same time, two sets of filter element replacement methods are provided. The operator can implement different replacement methods according to actual conditions, and it is more convenient to replace the filter element. BRIEF DESCRIPTION OF THE DRAWINGS

A contact frame 22 is fixedly connected to the left surface of the moving rack plate 20. A contact ring 23 is fixedly connected to the right surface of the moving rack plate 21. Both the moving rack plate 20 and the moving rack plate 21 are slidably mounted at the upper and lower ends of the stabilizing frame 18. Before installing the lower shell 1 of the purifier and the upper shell 4 of the purifier, first First, install the filter element body 5 to the surface of the purifier lower shell 1 and the purifier base 2. At the same time, the lower end of the filter element body 5 is provided with a groove adapted to the positioning column 6, so that the filter element body 5 can be positioned and installed through the positioning column 6, and then the purifier upper shell 4 is aligned with the purifier lower shell 1 and moves downward. Then the purifier upper shell 4 will drive the first moving plate 11 and the second moving plate 12 to descend. When the first moving plate 11 moves downward, the left surface of the first moving plate 11 will fit the left inner wall of the lower shell 1 of the purifier, and then the first moving plate 11 will drive the connecting plate 13, the first pressing block 14 and the first rack plate 15 to descend at the same time. During the descent, the first rack plate 15 is meshed with the first gear 17. At this time, the first gear 17 starts to rotate counterclockwise, and the The first gear 17 is limited by the rotating column 16, and then the second gear 19 is driven to rotate by the first gear 17. At this time, the second gear 19 will also rotate counterclockwise, and the second gear 19 will respectively mesh with the moving rack plate 20 and the movable rack plate 21. At this time, the moving rack plate 20 drives the contact frame 22 to move to the left, and the movable rack plate 21 drives the contact ring 23 to move to the right.

The installation stability of the filter element 5 is good, and at the same time, the left side surface of the abutment frame 22 will also abut the right side surface of the first moving plate 11, thereby enhancing the installation stability of the first moving plate 11. At the same time, the abutment ring 23 will fit the left side surface of the filter element body 5 to fix the position of the filter element body 5, thereby preventing the filter element body 5 from shaking during the subsequent transportation of the lower shell 1 of the purifier as a whole. The overall stability is good, and the first moving plate 11 will drive the first pressing block 14 to descend, and the first pressing block 14 will press the filter element body 5 to move downward. At this time, the filter element body 5 is on the surface of the positioning column 6, and then when the filter element body 5 continues to move downward, the groove at the bottom of the filter element body 5 is adapted to the elastic tube 8, and the elastic tube 8 will be pressed downward by the filter element body 5, and the spring body 9 begins to compress.The telescopic cylinder 10 limits the movement of the spring body 9, so that the entire filter element body 5 is also limited and fixed. This design can ensure the stability of the installation between the purifier upper shell 4 and the purifier lower shell 1 through the downward movement of the purifier upper shell 4, and ensure that the first moving plate 11 can be magnetically fixed with the iron plate 37 on the inner wall of the purifier lower shell 1. At the same time, the first moving plate 11 is strengthened by the contact frame 22 contacting the first moving plate 11, and then the upper and left surfaces of the filter element body 5 are limited by the movement of the contact ring 23 and the first pressing block 14, thereby solving the problem that the purifier shell cannot be installed and locked at one time in the past.

The inner bottom wall of the lower shell 1 of the purifier is connected with a rotating shell 33 through a hinge. An iron block 34 is installed inside the rotating shell 33. A magnet body 35 is installed inside the lower shell 1 of the purifier. The magnet body 35 and the iron block 34 are magnetically installed. A first rotating gear 25 is installed on the left side surface of the rotating shell 33. A second rotating gear 26 is installed on the left side of the first rotating gear 25. The second rotating gear 26 and the second moving plate 12 are meshed with each other. The lower surface of the first rotating gear 25 is meshed with a second rack plate 27. The back of the second rack plate 27 is fixedly connected to a limiting plate 28. A sliding block 29 is installed on the right side surface of the second rack plate 27. The sliding block 29 is in the rotating shell 33. The left inner wall of the filter element 5 is slidably installed, a worm 30 is installed on the right surface of the first rotating gear 25, and a worm wheel 31 is meshed and connected on the lower surface of the worm 30, and a motor body 32 is installed on the back of the worm wheel 31. The worm 30, the worm wheel 31 and the motor body 32 are installed inside the rotating shell 33, and the right surface of the first moving plate 11 abuts against the left surface of the abutment frame 22, and the lower surface of the first pressing block 14 abuts against the upper surface of the filter element body 5. When the first moving plate 11 moves downward, the second moving plate 12 will also move downward. Before the upper shell 4 of the purifier moves downward, the rotating shell 33 is first rotated until the iron block 34 is magnetically attracted to the magnet body 35, and then when the second moving plate 12 descends, the back of the second moving plate 12 abuts against the second The rotating gears 26 are meshed, and then the second rotating gear 26 will also rotate counterclockwise, and then the second rotating gear 26 drives the first rotating gear 25 to rotate, and then the first rotating gear 25 will drive the second rack plate 27 and the limit plate 28 to move to the back side when rotating, and the sliding block 29 is slidably installed inside the rotating shell 33, so that the second rack plate 27 and the limit plate 28 can slide stably, and when the second moving plate 12 stops moving, the back side of the limit plate 28 will contact the back side of the inner wall of the lower shell 1 of the purifier, so the lower shell 1 of the purifier and the rotating shell 33 can be locked by the limit plate 28, and at the same time, the second pressing block 24 on the left side of the movable rack plate 21 will also press on the upper surface of the filter element body 5,The cooperation between the second pressing block 24 and the first pressing block 14 can stably press and fix the filter element body 5, and the overall filter element body 5 has good installation stability. When the filter element body 5 needs to be removed later, the first method can directly take the purifier upper shell 4 from the top surface of the purifier lower shell 1 and move it upward, so that the first moving plate 11 and the second moving plate 12 will also move upward, so that the contact frame 22 and the contact ring 23 will return to their original positions. Therefore, the first moving plate 11 and the filter element body 5 are both released from the limit lock. When the top surface of the filter element body 5 is released from the limit, the spring body 9 is not pressed by the filter element body 5. At this time, the spring body 9 begins to return to its original position and can push the filter element body 5 upward, so that the purifier upper shell 4 can be quickly removed from the top surface of the purifier lower shell 1. The second method is to press the control button 36, and then the motor body 32 is started, and the motor body 32 drives the worm gear 31 to rotate, and then the worm gear 31 drives the worm gear 31 to rotate. The rod 30 rotates, and then the worm 30 drives the first rotating gear 25 and the second rotating gear 26 to rotate. At this time, the second rotating gear 26 starts to rotate clockwise, and the second moving plate 12 moves upward. At the same time, the second rack plate 27 and the limit plate 28 also move forward, so the limit between the rotating shell 33 and the lower shell 1 of the purifier is released. At the same time, the second moving plate 12 also drives the upper shell 4 of the purifier slightly upward. At this time, the top surface of the filter element body 5 also contacts the limit, and then the rotating shell 33 can be rotated, so that the filter element body 5 inside the lower shell 1 of the purifier can be taken out and replaced. After taking it out, the rotating shell 33 is rotated again to re-magnetize the iron block 34 and the magnet body 35. The design can press and fix the top surface of the filter element body 5 synchronously to ensure the stability of the filter element body 5 during installation and use.

[0037] Working principle: When the staff uses the device, first connect the device to an external power supply to provide power support for the device. Before installing the purifier lower shell 1 and the purifier upper shell 4, first install the filter element body 5 to the surface of the purifier lower shell 1 and the purifier base 2. At the same time, the lower end of the filter element body 5 is provided with a groove adapted to the positioning column 6, so that the filter element body 5 can be positioned and installed through the positioning column 6. Then, the purifier upper shell 4 is aligned with the purifier lower shell 1 and moves downward. Then, the purifier upper shell 4 will drive the first moving plate 11 and the second moving plate 12 to descend. When the first moving plate 11 moves downward, the left surface of the first moving plate 11 will fit the left inner wall of the purifier lower shell 1, and then the first moving plate 11 will move downward. The movable plate 11 will drive the connecting plate 13, the first pressing block 14 and the first rack plate 15 to descend at the same time. During the descent process, the first rack plate 15 meshes with the first gear 17. At this time, the first gear 17 starts to rotate counterclockwise, and the first gear 17 is limited by the rotating column 16. Then, the second gear 19 is driven to rotate by the first gear 17. At this time, the second gear 19 will also rotate counterclockwise. The second gear 19 is respectively meshed with the moving rack plate 20 and the moving rack plate 21. At this time, the moving rack plate 20 drives the contact frame 22 to move to the left, and the moving rack plate 21 drives the contact ring 23 to move to the right. When the contact frame 22 moves, it will slowly conflict with the right side of the first moving plate 11, and the contact ring 23 will also slowly move to the right. The first moving plate 11 will drive the first pressing block 14 to descend, and the first pressing block 14 will press the filter element body 5 to move downward. At this time, the filter element body 5 is on the surface of the positioning column 6, and then when the filter element body 5 continues to move downward, the filter element body 5 will be moved downward by the first moving plate 11. , at this time, the groove at the bottom end of the filter element body 5 is adapted to the elastic tube 8, and the elastic tube 8 is pressed downward by the filter element body 5. At this time, the spring body 9 begins to compress, and the telescopic tube 10 limits the movement of the spring body 9, so that the entire filter element body 5 is also limited and fixed. The design moves the purifier upper shell 4 downward, firstly, it can ensure the stability of the installation between the purifier upper shell 4 and the purifier lower shell 1, and ensure that the first moving plate 11 can be magnetically fixed with the iron plate 37 on the inner wall of the purifier lower shell 1. At the same time, the first moving plate 11 is strengthened by the contact frame 22 contacting the first moving plate 11, and then the upper and left surfaces of the filter element body 5 are limited by the movement of the contact ring 23 and the first pressing block 14;

[0038] When the first moving plate 11 moves downward, the second moving plate 12 will also move downward. Before the upper shell 4 of the purifier moves downward, the rotating shell 33 is first rotated until the iron block 34 and the magnet body 35 are magnetically installed. Then, when the second moving plate 12 descends, the back of the second moving plate 12 is meshed with the second rotating gear 26, and then the second rotating gear 26 will also rotate counterclockwise. Subsequently, the second rotating gear 26 drives the first rotating gear 25 to rotate. Then, when the first rotating gear 25 rotates, it drives the second rack plate 27 and the limit plate 28 to move to the back, and the sliding block 29 is slidably installed inside the rotating shell 33, so that the second rack plate 2 7 and the limiting plate 28 can slide stably. When the second moving plate 12 stops moving, the back of the limiting plate 28 will contact the back of the inner wall of the lower shell 1 of the purifier. Therefore, the lower shell 1 of the purifier and the rotating shell 33 can be limited and locked by the limiting plate 28. At the same time, the second pressing block 24 on the left side of the movable rack plate 21 will also be pressed on the upper surface of the filter element body 5. The filter element body 5 can be stably pressed and fixed by the cooperation between the second pressing block 24 and the first pressing block 14. When the filter element body 5 needs to be taken out later, the first method can directly take the purifier upper shell 4 from the top surface of the lower shell 1 of the purifier and move it upward, so that the first moving plate 11 and the second The moving plate 12 will also move upward, so that the abutment frame 22 and the abutment ring 23 will return to their original positions, so that the first moving plate 11 and the filter element body 5 are both released from the limit lock. When the top surface of the filter element body 5 is released from the limit, the spring body 9 is not pressed by the filter element body 5. At this time, the spring body 9 begins to return to its original position and can push the filter element body 5 upward, so that the purifier upper shell 4 can be quickly removed from the top surface of the purifier lower shell 1. The second method is to press the control button 36, and then the motor body 32 is started, and the motor body 32 drives the worm wheel 31 to rotate, and then the worm 30 is driven to rotate through the worm wheel 31, and then the worm 30 drives the first rotating gear 25 and the second The rotating gear 26 rotates, and the second rotating gear 26 starts to rotate clockwise. At this time, the second moving plate 12 will move upward, and the second rack plate 27 and the limit plate 28 will also move forward. Therefore, the limit between the rotating shell 33 and the lower shell 1 of the purifier is released. At the same time, the second moving plate 12 will also drive the upper shell 4 of the purifier slightly upward. At this time, the top surface of the filter element body 5 also contacts the limit, and then the rotating shell 33 can be rotated to take out and replace the filter element body 5 inside the lower shell 1 of the purifier. After taking it out, the rotating shell 33 is rotated again to re-magnetize the iron block 34 and the magnet body 35. The above is all the working principles of the present invention.
