Description

Technical Field

[0001] The utility model relates to the field of filters, in particular to a combined filter structure. Background Art

[0002] A filter is a device used to purify impurities, particles and pollutants from tap water or other water sources. Water filters usually include different filter media, such as activated carbon, ceramics, fiber filters, etc. These media can remove harmful substances from water and improve the quality and taste of water. Water filters can be installed on faucets, in kettles or in the water supply system of the entire house to provide clean and healthy drinking water. Using water filters can reduce substances such as bacteria, viruses, heavy metals, chlorine and odor in water to ensure the safety of drinking water.

[0003] After searching, Chinese patent announcement number: CN219231680U discloses a combined disc filter, including a water outlet main pipe, a support seat is welded at the bottom of the water outlet main pipe, and a plurality of mounting seats are fixedly connected to the top of the water outlet main pipe, and a filter head body is provided on the mounting seat; the front and rear sides of the mounting seat are fixedly connected with a positioning mechanism, and the plug-in end of the positioning mechanism is plugged with the filter head body, and the positioning mechanism includes a fixing frame, and the fixing frame is welded to the outside of the mounting seat, and a screw is provided on the outside of the fixing frame. The right end of the screw penetrates the fixing frame and extends to the outside thereof and is fixedly connected with a rotating block. The combined disc filter has a reasonable structural design and is easy to use. The filter head is installed by a snap-on method. When it is damaged, it can be quickly dismantled for maintenance or replacement. It has high practicality, reduces the cost of use, and can fully meet the use requirements.

[0004] Although the above device sets a positioning mechanism so that the filter head can be directly installed by snap-fitting, it is necessary to rotate the threads on both sides during installation, and multiple filter heads are installed on the main water pipe. This results in the need to repeatedly rotate multiple screws to disassemble and assemble the filter heads when replacing the filter heads, which is relatively time-consuming. Therefore, a combined filter structure is proposed to solve the above problem. Utility Model Content
