[0023] like Figures 1 to 5 As shown, the utility model is a high-efficiency air purifier, comprising: a purifier housing 1, a conical groove 101 is provided at the bottom of the purifier housing 1, and a collecting assembly 8 is provided at the bottom of the conical groove 101, three columns 2 are fixedly installed at equal intervals along the circumference of the surface of the conical groove 101, a support plate 3 is fixedly installed between the tops of the three columns 2, a cylindrical filter element 4 is placed on the top of the support plate 3, an axial flow fan 5 is fixedly installed on the top of the purifier housing 1, and the air inlet end of the axial flow fan 5 is mounted on the top of the cylindrical filter element 4, a cover plate 6 is rotatably installed on the upper end of the axial flow fan 5, and air outlets 601 are provided on both sides of the cover plate 6, and the air outlet end of the axial flow fan 5 is located inside the cover plate 6 A cleaning assembly 7 for cleaning dust on the surface of the cylindrical filter element 4 is provided between the bottom of the support plate 3 and the inner wall of the purifier housing 1. Through the provision of the cleaning assembly 7, the bristles on one side of the two symmetrical arc-shaped brush plates 705 sweep away impurities such as catkins attached to the outer wall of the cylindrical filter element 4, thereby reducing the blockage of the filter pores on the surface of the cylindrical filter element 4 and improving the air filtration efficiency. At the same time, the gear 706 at the top of the reciprocating screw 703 engages and rotates with the gear ring 707 at the bottom of the cover plate 6, causing the cover plate 6 to rotate. The rotation of the air outlet 601 helps to more evenly distribute the purified air and improve the efficiency of indoor air purification. A door panel 9 is detachably mounted on one side of the purifier housing 1. The provision of the door panel 9 facilitates the removal and replacement of the cylindrical filter element 4.

[0024] The collection assembly 8 includes a first magnetic ring 801, which is fixedly mounted at the bottom of the tapered groove 101. A second magnetic ring 802 is attracted to the bottom of the first magnetic ring 801. The first and second magnetic rings 801 and 802 attract each other with opposite magnetic poles, and a collection box 803 is fixedly mounted at the bottom of the second magnetic ring 802. After the two symmetrical curved brush plates 705 sweep dust from the outer wall of the cylindrical filter element 4, the dust falls through the tapered groove 101 at the bottom of the purifier housing 1 into the interior of the collection box 803 for collection. This prevents dust from accumulating at the bottom of the purifier housing 1 and reattaching to the outer wall of the cylindrical filter element 4, which could affect the air filtration efficiency.

[0025] A bearing is provided on the inner wall of the lower end of the cover plate 6, with the inner ring of the bearing fixedly connected to the surface of the axial flow fan 5, and the outer ring of the bearing fixedly connected to the inner wall of the cover plate 6. The bearing arrangement allows the cover plate 6 to rotate freely on the surface of the axial flow fan 5. After the purified air is discharged from the outlet end of the axial flow fan 5, the rotation of the cover plate 6 helps to more evenly distribute the purified air, thereby improving the efficiency of indoor air purification.

[0026] The cleaning assembly 7 includes: a dual-axis motor 701, a reciprocating screw rod 703 and a gear ring 707. The dual-axis motor 701 is fixedly installed in the middle position of the bottom of the support plate 3. The output ends on both sides of the dual-axis motor 701 are fixedly installed with bevel gear shafts 702. There are two reciprocating screw rods 703. The two reciprocating screw rods 703 are symmetrically mounted in the vertical direction for rotation inside the purifier housing 1. The surface of the upper end of the reciprocating screw rod 703 and the top of the purifier housing 1 are rotatably mounted through a sealed bearing to improve the sealing between the reciprocating screw rod 703 and the top of the purifier housing 1. The bottom of the reciprocating screw rod 703 is fixed. It is fixedly connected with a bevel gear 704, and the surface of the bevel gear 704 is meshed with one end of the adjacent bevel gear shaft 702. The surface of the upper end of the reciprocating screw rod 703 is threadedly installed with an arc-shaped brush plate 705, and one side of the arc-shaped brush plate 705 is placed on the outer wall of the air inlet end of the axial flow fan 5. The outer wall of the air inlet end of the axial flow fan 5 is flush with the outer wall of the cylindrical filter element 4. The other side of the arc-shaped brush plate 705 is slidably installed on the inner wall of the purifier housing 1. The top of the reciprocating screw rod 703 is fixedly connected with a gear 706, and the bottom of the cover plate 6 is fixedly installed with a gear ring 707. The surface of the gear 706 is meshed with the inner wall of the gear ring 707. When the household air purifier is used for a long time, especially in spring, a large amount of dust, catkins and other impurities will adhere to the outer wall of the cylindrical filter element 4, resulting in a decrease in the air filtration efficiency of the cylindrical filter element 4. At this time, by starting the dual-axis motor 701, the dual-axis motor 701 drives the output ends on both sides to rotate in the same direction. At this time, the bevel gear shaft 702 at the output end of the dual-axis motor 701 is engaged with the bevel gear 704 at the bottom of the reciprocating screw rod 703, so that the arc-shaped brush plate 705 threadedly installed on the surface of the reciprocating screw rod 703 moves up and down, and the bristles on one side of the arc-shaped brush plate 705 push the cylindrical filter element 4 Impurities such as catkins attached to the outer wall are swept off, and the swept-off dust and catkins fall into the interior of the collection box 803 through the conical groove 101 at the bottom of the purifier shell 1 for collection, thereby reducing the blockage of the filter holes on the surface of the cylindrical filter element 4 and improving the air filtration efficiency. In addition, when the reciprocating screw 703 rotates, the gear 706 at the top of the reciprocating screw 703 engages and rotates with the gear ring 707 at the bottom of the cover plate 6, causing the cover plate 6 to rotate. The rotation of the air outlet 601 helps to distribute the purified air more evenly, improve the efficiency of indoor air purification, and make the air purification more efficient.

[0027] The bottom of the reciprocating screw rod 703 is rotatably mounted with a support block 7031, and one side of the support block 7031 is fixedly connected to the inner wall of the purifier housing 1. The setting of the support block 7031 supports the lower end of the reciprocating screw rod 703 and improves the rotation stability of the reciprocating screw rod 703.

[0028] The front and rear sides of the purifier housing 1 are provided with mounting slots, and an air exchange net 10 is fixedly installed inside the mounting slots. By providing the air exchange net 10 on both the front and rear sides of the purifier housing 1, the flow of surrounding air can be increased during operation of the air purifier, thereby improving purification efficiency.

[0029] Working principle: When the power is turned on and the air purifier is used for a long time at home, especially in spring, a large amount of dust, catkins and other impurities will adhere to the outer wall of the cylindrical filter element 4, which will reduce the air filtration efficiency of the cylindrical filter element 4. At this time, by starting the dual-axis motor 701, the dual-axis motor 701 drives the output ends on both sides to rotate in the same direction. At this time, the bevel gear shaft 702 at the output end of the dual-axis motor 701 is engaged with the bevel gear 704 at the bottom of the reciprocating screw rod 703, so that the arc brush plate 705 threadedly installed on the surface of the reciprocating screw rod 703 moves up and down, and the arc brush plate 705 The bristles on one side sweep away impurities such as catkins attached to the outer wall of the cylindrical filter element 4, and the swept dust and catkins fall into the interior of the collection box 803 through the conical groove 101 at the bottom of the purifier shell 1 for collection, thereby reducing the blockage of the filter holes on the surface of the cylindrical filter element 4 and improving the air filtration efficiency. In addition, when the reciprocating screw 703 rotates, the gear 706 at the top of the reciprocating screw 703 engages and rotates with the gear ring 707 at the bottom of the cover plate 6, causing the cover plate 6 to rotate. The rotation of the air outlet 601 helps to distribute the purified air more evenly and improve the efficiency of indoor air purification.
