Description

Technical Field

[0001] The utility model relates to the technical field of filter discs, in particular to a filter disc for water purification. Background Art

[0002] The filter disc is a commonly used filter structure in water purifiers or water purification equipment. Filter material is placed on the filter disc for water purification.

[0003] The current filter disc filters and purifies water by placing activated carbon particles. However, the activated carbon particles are not effectively limited when placed in the filter disc. Therefore, when the filter disc is removed, the activated carbon particles may be scattered on the ground or inside the water purifier, causing inconvenience to users or staff. Therefore, the present application proposes a filter disc for water purification. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0020] like Figures 1-4 As shown, the embodiment of the present invention provides a filter disc for water purification, comprising:

[0021] The base 1 has an annular groove 2 on its outer wall, and the annular groove 2 is used to install a sealing ring. In this way, the filter disc is installed in the chamber inside the water purifier. The sealing ring can ensure the sealing between the filter disc and the water purifier, thereby more effectively purifying the clean water.

[0022] A plurality of water leakage holes 9 are provided on the base 1, and a limiting ring 7 is fixedly provided on the middle part of the base 1, which can be installed on the guide column inside the water purifier, or sleeved on the connecting pipe at the upper end of the water purifier filter element; a connecting ring 3 is fixed on the base 1, and a plurality of annular ribs 4 are fixed on the outer wall of the connecting ring 3. The base 1, the annular ribs 4 and the connecting ring 3 are integrally formed, and the plurality of annular ribs 4 are distributed in a linear array in the axial direction of the connecting ring 3. An annular limiting groove 5 is formed between two adjacent annular ribs 4, and a rubber ring or a sealing ring can be installed on the annular limiting groove 5. Since a circular groove is provided at the bottom of the base 1, the outer diameter of the circular groove matches the outer diameter of the annular rib 4, so that a plurality of filter discs can be stacked together to realize the installation between multiple filter discs.

[0023] A plurality of arc-shaped plates 8 are provided in the connecting ring 3, and the arc-shaped plates 8 are fixedly connected to the base 1 and the connecting ring 3. A filter cavity 10 is formed between two adjacent arc-shaped plates 8, and a filter unit 6 is placed in the filter cavity 10. The filter unit 6 includes a filter box 11 placed in the filter cavity 10, and a plurality of water outlet holes 14 are penetrated at the bottom of the filter box 11. A detachable upper cover 12 is installed on the upper end of the filter box 11, and a plurality of water inlet holes 13 are penetrated on the upper cover 12. Activated carbon particles are filled between the filter box 11 and the upper cover 12, and a mounting ring 15 matching the inner wall of the filter box 11 is fixed to the bottom of the upper cover 12. A rubber membrane is fixed to the outer wall of the mounting ring 15. When the mounting ring 15 is installed in the filter box 11 and the upper cover 12 abuts against the filter box 11, the rubber membrane abuts against the inner wall of the filter box 11, and the friction force of the rubber membrane is utilized to connect the upper cover 12 to the filter box 11.

[0024] The activated carbon particles can be limited by the filter unit 6 to avoid the disadvantage of scattering the activated carbon particles when the filter disc is taken out. Since multiple filter units 6 are set and some filter units 6 have more impurities after being used for a period of time, the filter units 6 with more impurities can be replaced in a targeted manner to reduce the waste of activated carbon particles.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
