Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaners, and in particular to a filter structure for vacuum cleaners. Background Technology

[0002] A vacuum cleaner is a dust-collecting device that uses a motor to drive blades to rotate at high speed, creating negative air pressure inside a sealed casing to suck up dust and debris.

[0003] A filter cartridge typically consists of an upper cover, a bottom plate, and filter media. The filter media is located between the upper cover and the bottom plate. The filter media is made of filter paper or filter cloth and consists of multiple corrugated flaps. During installation and use, due to air pressure, the corrugated flaps may stick together, causing air tightness and affecting the filter cartridge's filtration efficiency and air permeability. Additionally, impurities may accumulate between the bottom plate and the gaps in the corrugated flaps, similarly affecting the filter cartridge's filtration performance. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 4In this embodiment of the present invention, a filter element structure 100 includes: an upper cover plate 10, a bottom plate 20, and a filter material 30. The filter material 30 is made of folded filter cloth or filter paper. The filter material 30 forms multiple corrugated flaps 31. The corrugated flaps 31 extend radially. Both the upper cover plate 10 and the bottom plate 20 are provided with pressure plate portions 11. The pressure plate portions 11 are used to fix the ends of the filter material 30. Multiple equally spaced ribs 12 are formed on the pressure plate portions 11. The equally spaced ribs 12 are used to space adjacent corrugated flaps 31. The equally spaced ribs 12 and the corrugated flaps 31 are spaced apart. The corrugated flaps 31 protrude radially from the pressure plate portions 11. The equally spaced ribs 12 are arranged at equal intervals.

[0024] In one specific embodiment, a filter element structure 100 further includes an inner support mesh 40. The inner support mesh 40 supports the filter material 30 from the inside. The filter material 30 surrounds the inner support mesh 40. The two ends of the inner support mesh 40 are respectively fixed to the upper cover plate 10 and the bottom plate 20.

[0025] In one specific implementation, both the upper cover plate 10 and the bottom plate 20 have an inner ring edge 13. The inner ring edge 13 is used to fix the inner support net 40. The inner wall of the inner support net 40 is disposed on the outer periphery of the inner ring edge 13.

[0026] In one specific implementation, the corrugated hinge 31 has bulges 311 on both sides. The bulges 311 are recessed inward. The bulges 311 on both sides are joined together. Through the joining of the bulges 311, a gap is formed between the two sides of the corrugated hinge 31 to allow airflow to pass through and improve filtration efficiency.

[0027] In one specific implementation, sealant is applied to the ends of the corrugated hinge 31. The sealant seals the ends of both ends of the corrugated hinge 31.

[0028] In one specific embodiment, the two ends of the filter material 30 are fixed to the pressure plate portion 11 with adhesive. Alternatively, adhesive can be applied to the pressure plate portion 11, and then the filter material 30 can be adhered to the adhesive. In another optional embodiment, an adhesive groove can be provided on the pressure plate portion 11 to facilitate the bonding of the filter material 30 and the pressure plate portion 11 using adhesive.

[0029] In one specific embodiment, a filter element structure 100 further includes a sealing device 50. The sealing device 50 is installed to the upper cover plate 10. The sealing device 50 achieves a seal between the filter element structure 100 and the mating installation position.

[0030] As one specific implementation, the base plate 20 is provided with a disassembly and assembly gripper. Users can use the disassembly and assembly gripper to disassemble and install the filter element structure 100.
