The air purifier includes a composite filter cartridge. The existing composite filter cartridge includes a filter cartridge with a corrugated structure. After long-term use, dust and other impurities are easily mixed and adsorbed on the outer side wall of the filter cartridge, resulting in large resistance to air filtration and affecting the air intake efficiency. Content of the Utility Model

[0004] Therefore, the utility model provides a high-efficiency and low-resistance composite filter cartridge to solve the problem that dust in the prior art easily clogs the filter cartridge and affects the air intake efficiency of the air filter cartridge.

[0027] The terms such as "upper", "lower", "left", "right", "middle" cited in this specification are only for the convenience of description and clarity, rather than to limit the scope of implementation of the present utility model. The change or adjustment of their relative relationships shall also be regarded as the scope of implementation of the present utility model without substantial change in the technical content.

[0028] Please refer to Figures 1-6 , the present utility model provides a high-efficiency and low-resistance composite filter element, including a composite filter element ring 30 and a support base 10 for supporting the composite filter element ring 30.

[0029] The upper end of the support base 10 is provided with an outer net 20 and an inner net 40, and the composite filter element ring 30 is located between the outer net 20 and the inner net 40.

[0030] The upper end of the support base 10 is provided with a first limiting groove 11 for limiting the outer net 20, the composite filter element ring 30 and the inner net 40. The outer net 20, the composite filter element ring 30 and the inner net 40 are sequentially placed in the cavity of the first limiting groove 11. The outer of the inner net 40 is sleeved with the composite filter element ring 30, and the outer of the composite filter element ring 30 is sleeved with the outer net 20. The outer net 20 is used to block large-particle dust impurities.

[0031] A plurality of dust cleaning plates 100 for facilitating the dust cleaning of the composite filter element ring 30 and the outer net 20 are installed on the outer wall of the inner net 40. The composite filter element ring 30 is corrugated. An external groove is arranged on the side close to the outer net 20, and an internal groove is arranged on the side close to the inner net 40. The dust cleaning plate 100 is located in the middle of the internal groove. Air moves from the outer net 20 towards the inner net 40. Therefore, impurities are easily adsorbed at the external groove of the outer net 20 and the composite filter element ring 30. When the dust cleaning plate 100 touches both sides of the internal groove, the impurities adsorbed on the external groove are bounced off.

[0032] One end of the dust cleaning plate 100 is fixedly installed with a long rod 110 for limiting the dust cleaning plate 100, and a plurality of dust cleaning plates 100 are installed at the upper end of the long rod 110. A gear 111 is fixedly installed at the lower end of the long rod 110.

[0033] A plurality of limiting holes 12 for limiting the long rod 110 are arranged in the cavity of the first limiting groove 11. The long rod 110 penetrates through the limiting holes 12 and extends to the lower end of the support base 10. An installation groove 13 for limiting the rotating assembly 200 is arranged on the side wall of the lower end of the support base 10. The cross section of the installation groove 13 is L-shaped. The installation groove 13 is divided into a horizontal groove and a vertical groove. The vertical groove is provided to facilitate the installation and disassembly of the rotating assembly 200, and the horizontal groove is provided to facilitate the rotation of the rotating assembly 200.

[0034] A second limiting groove 14 for limiting the rotating assembly 200 is arranged at the bottom end of the support base 10. Through the processing of the second limiting groove 14, two annular blocks are formed at the bottom of the support base 10. The annular block with a smaller diameter is cut, so that the height of the annular block with a smaller diameter plus the thickness of the handle 230 is less than that of the annular block with a larger diameter. Therefore, after the rotating assembly 200 is installed, the bottom horizontal height of the handle 230 is higher than the annular block with a larger diameter at the lower end of the support base 10, ensuring the stability of the support base 10 when the support base 10 is installed.

[0035] A plurality of first limiting vertical rods 21 for stabilizing the external network 20 are installed in the middle of the external network 20, and a plurality of second limiting vertical rods 41 for stabilizing the internal network 40 are installed in the middle of the internal network 40. A plurality of limiting blocks 42 for limiting the long rod 110 are fixedly installed on the outer wall of the second limiting vertical rod 41.

[0036] A rotating assembly 200 for controlling the rotation of a plurality of gears 111 is installed at the lower end of the support base 10. The rotating assembly 200 includes a first annular block 210. A second annular block 220 is fixedly installed at the upper end of the first annular block 210. A plurality of tooth blocks 221 for meshing with the gears 111 are fixedly installed on the inner wall of the second annular block 220. A handle 230 for facilitating the rotation of the first annular block 210 is fixedly installed at the lower end of the first annular block 210. Sliders 231 for sliding in the cavity of the installation groove 13 are fixedly installed at both ends of the handle 230.

[0037] When the outer wall of the external network 20 and the external groove of the composite filter element ring 30 are blocked, the first annular block 210 is reciprocally rotated by holding the handle 230, so that the slider 231 reciprocally slides in the transverse groove of the installation groove 13 and synchronously drives the tooth block 221 to rotate, so that the tooth block 221 meshing with the gear 111 drives the gear 111 to rotate forward and backward, synchronously drives the long rod 110 to rotate, so that the dust cleaning plate 100 swings, and pats both sides of the internal groove of the composite filter element ring 30, shakes off the impurities in the external groove of the composite filter element ring 30, and the vibration generated by the patting synchronously drives the external network 20 to vibrate, so that the impurities adhered to the outer wall of the external network 20 fall downward, so as to prevent the existence of impurities from affecting the air intake efficiency of the present invention.

[0038] Although the present invention has been described in detail with general descriptions and specific embodiments above, on the basis of the present invention, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present invention all fall within the scope of protection required by the present invention.
