[0030] Please see Figures 2 to 8 An air purifier with a dual-fan duct structure includes a housing 1. A plurality of housing air inlets 2 are evenly distributed in the middle of the outer wall of the housing 1. A plurality of housing air outlets 3 are located above and below the housing air inlets 2 on both sides of the housing 1. Motor fan wheels 7 are respectively installed at the upper and lower ends of the housing 1, located inside the housing air outlets 3. A duct support 6 is fixedly sleeved on the outer wall of the motor fan wheel 7, and the duct support 6 is connected to the inner wall of the housing 1. Through the rotation of the motor fan wheel 7, air from outside the housing 1 enters the housing 1 through the housing air inlets 2. Inside, the air entering the air inlet 2 of the casing is filtered by the filter assembly, and then the filtered air is discharged from the air outlet 3 at the upper and lower ends of the casing. At this time, the air volume is increased to a level that a single impeller cannot achieve by the dual impeller structure with the motor impeller 7 installed at the upper and lower ends, which greatly increases the purification effect. Furthermore, by assembling the motor impeller 7 at the upper and lower ends of the casing 1, with the filter assembly in the middle, a stable air duct structure is formed. The filter assembly located inside the air inlet 2 of the casing is installed between the motor impeller 7 at the upper and lower ends.

[0031] The air duct support 6 includes a first support plate 601 and a second support plate 602. The first support plate 601 is installed on the outside of the motor impeller 7, and the second support plate 602 is installed on the inside of the motor impeller 7.

[0032] The filter assembly includes a HEPA filter 5 and two honeycomb meshes 4. The upper end of the HEPA filter 5 is connected to one honeycomb mesh 4, and the lower end plate of the HEPA filter 5 is connected to the other honeycomb mesh 4. The filter assembly is installed between the upper and lower duct supports 6.

[0033] The filter assembly includes a HEPA filter 5, the pores of which are filled with carbon blocks.

[0034] Please see Figure 1 , Figures 9 to 12 A base 8 is movably mounted on the lower end of the housing 1. Movable plates 9 are provided on the base 8 in four directions, and soft pads are installed on the inner side of each movable plate 9. Connecting rods 10 are fixedly mounted on both ends of the outer side of the movable plates 9. A side plate 11 is fixedly connected to the end of the connecting rod 10 away from the movable plate 9. A moving component 12 is fixedly mounted on the lower end of the side plate 11. A rotating shaft 13 is fixedly sleeved on the inner wall of the moving component 12, and the outer walls at both ends of the rotating shaft 13 are movably sleeved with the inner walls of the base 8. A first knob 14 located outside the housing 1 is fixedly mounted on the outer end of the rotating shaft 13. A limiting component 15 located inside the first knob 14 is provided on the outer wall of the rotating shaft 13, restricting the movement of the moving component 12. A first threaded rod 16 is movably connected to the outer side of the limiting component 15. A second knob 18 is fixedly installed at the end of the threaded rod 16 away from the limiting component 15. The second knob 18 facilitates the operation of the first threaded rod 16. The outer wall of the first threaded rod 16 is threaded with a mounting plate 17 located inside the second knob 18, and the inner end of the mounting plate 17 is fixedly connected to the outer wall of the base 8. Extension plates 20 are fixedly installed in all four directions of the base 8. A second threaded rod 21 is threadedly installed on the inner wall of the extension plate 20 away from the base 8. A third knob 22 located above the extension plate 20 is fixedly installed at the upper end of the second threaded rod 21. A pressure plate 23 located below the extension plate 20 is fixedly connected at the lower end of the second threaded rod 21. A universal wheel 19 is movably connected to the lower end face of the base 8. By using the rolling of the universal wheel 19, the movement of the base 8 can drive the movement of the housing 1.

[0035] The inner end of the connecting rod 10 is fixedly connected to the outer side of the movable plate 9. The connecting rod 10 is used to connect the movable plate 9 and the side plate 11. The outer end of the connecting rod 10 is fixedly connected to the inner side of the side plate 11.

[0036] The movable assembly 12 includes a ball nut 121 and a ball screw 122. Rotation of the rotating shaft 13 via the first horizontal knob 14 causes the ball screw 122 on both sides to have threads in opposite directions on its outer walls. The threaded connection between the ball screw 122 and the ball nut 121 allows the horizontal rotation of the rotating shaft 13 to drive the movement of the connecting rods 10 on both sides through the connection of the ball screw 122 and the ball nut 121, until the movable plate 9 is connected to the machine. When the housing 1 contacts, the connecting rods 10 on the left and right sides of the housing 1 can be adjusted to clamp the movable plate 9. The inner wall of the ball nut 121 is threadedly connected to the outer wall of the ball screw 122. The inner wall of the ball screw 122 is fixedly connected to the outer wall of the rotating shaft 13. The upper end of the ball nut 121 is fixedly connected to the lower end of the side plate 11. The outer walls of the ball screw 122 at both ends in the horizontal direction are provided with threads in opposite directions. The outer walls of the ball screw 122 at both ends in the vertical direction are provided with threads in opposite directions.

[0037] The limiting assembly 15 includes a limiting gear 151 and a limiting block 152. After the movable plate 9 in four directions is adjusted, the first threaded rod 16 is rotated by the second knob 18. Due to the threaded connection between the mounting plate 17 and the first threaded rod 16, the first threaded rod 16 rotates in a circular motion while moving horizontally. The movement of the first threaded rod 16 drives the movement of the limiting block 152 until the limiting block 152 is engaged between two adjacent teeth of the limiting gear 151, thus limiting the movement of the rotating shaft 13. The inner wall of the limiting gear 151 is fixedly sleeved with the outer wall of the rotating shaft 13, and the limiting block 152 is movably engaged with two adjacent teeth of the limiting gear 151. The outer side of the limiting block 152 is movably connected to the inner end of the first threaded rod 16.

[0038] Working principle: During use, the filter assembly is installed between the upper and lower motor impellers 7. When the filter assembly consists of a honeycomb mesh 4 and a HEPA filter 5, the product adopts a stacked form, combining the HEPA filter 5 with the honeycomb mesh 4 at the upper and lower ends to form a large filter. Furthermore, the HEPA filter 5 can also be replaced with a honeycomb carbon plate, which can achieve the same effect of purifying formaldehyde and organic matter. The air outlet 3 of the casing can be set to three-sided or four-sided air outlet. When the casing 1 is multi-faceted, it can also be set to multi-faceted air outlet. If the whole machine is circular, it can be set to full-circle air outlet. The same applies to the air inlet.

[0039] First, place the housing 1 on the base 8. Rotating the first horizontal knob 14 causes the shaft 13 to rotate. Because the ball screws 122 on the left and right sides have opposite threads on their outer walls, and the ball screws 122 and ball nuts 121 are threaded together, the rotation of the horizontal shaft 13 drives the connecting rods 10 on both sides through the connection of the ball screws 122 and ball nuts 121, until the movable plate 9 contacts the housing 1. This allows adjustment of the connecting rods 10 on the left and right sides of the housing 1 to clamp the movable plate 9. Then, rotating the vertical shaft 13 causes the ball screws 122 on the front and rear sides to rotate, until the movable plates 9 on the front and rear sides clamp the housing 1. The connecting rods 10 then limit the position of the movable plate 9 on the housing 1. The deformation of the pads on the movable plate 9 indicates the contact force between the housing 1 and the movable plate 9 in all four directions. After adjustment, the first threaded rod 16 is rotated by the second knob 18. Due to the threaded connection between the mounting plate 17 and the first threaded rod 16, the first threaded rod 16 rotates in a circular motion while simultaneously moving horizontally. The movement of the first threaded rod 16 also drives the movement of the limiting block 152 until the limiting block 152 is engaged between two adjacent teeth of the limiting gear 151, thus restricting the movement of the rotating shaft 13. Finally, through the rotation of the motor impeller 7, the air outside the casing 1 enters the interior of the casing 1 through the casing air inlet 2. The air entering the casing air inlet 2 is filtered by the filter assembly, and then the filtered air is discharged from the casing air outlet 3 at the upper and lower ends. At this time, through the dual impeller structure with the motor impeller 7 installed separately at the upper and lower ends, the air volume is increased to a level that a single impeller cannot achieve, greatly increasing the purification effect. Furthermore, by assembling the motor impeller 7 at the upper and lower ends inside the casing 1, with the filter assembly in the middle, a stable air duct structure is formed.
