Description

  The present invention relates to a cartridge filter for a filter that can enhance the filtration effect, can be taken out and recycled after a certain period of use, and does not need to discard the entire cartridge filter, and contributes to environmental protection.

A cartridge filter used in a general filter usually has a sealed tube body, a water inlet / outlet is formed in the tube body, and various filter media are arranged in the tube body, and water passes through the filter media. Foreign substances and bacteria can be filtered by passing.
However, after a certain period of time, the conventional cartridge filter has too many sources of contamination and the filtration effect is lost. Thus, the user discards the dirty cartridge filter and replaces it with a new one. Not only is it wasteful, but it also fails to meet environmental protection requirements.

  The problem to be solved by the present invention is to improve the filtration effect, and after a certain period of use, only the filtration layer can be taken out and recycled, and it is not necessary to discard the entire cartridge filter, contributing to environmental protection. It is to provide a cartridge filter for a machine.

  The cartridge filter of the filter of the present invention includes a tube, and an upper lid and a lower lid that are screwed to the tube, and a filtration layer of a different material is accommodated in the tube, and the upper lid and the lower lid are A water inlet and a water outlet are respectively provided, and a concave fitting tank is provided on the inner surface for fitting different types of filter media, and water that has entered from the water inlet of the upper lid passes through the filter media and the filter layer. Passed and filtered, discharged from the water outlet of the lower lid, and after use for a certain period of time, the upper lid and the lower lid are removed, and the filtration layer in the tubular body is taken out and can be recycled.

The recessed fitting tank provided in the circumferential direction of the upper lid and the lower lid forms a stepped portion having a larger diameter than the inner surfaces of the upper lid and the lower lid, and a recessed tank having a larger diameter than this is formed on the tip side of the stepped portion. The filter medium may be positioned by arranging the filter medium in the stepped portion and installing the C-shaped ring in the concave tank.
The filtration layer provided in the tube is preferably made of sand or an environment-friendly material that emits far infrared rays.
A male screw may be provided at each of an upper end and a lower end of the tube body, and a female screw to be engaged with the male screw of the tube body may be provided at the periphery of the opening of the upper lid and the lower lid.

  According to the cartridge filter of the filter of the present invention, the cartridge filter is obtained by combining the upper and lower lids, which are screwed to the upper and lower ends of the pipe body and arranged with different filter media, into the pipe body containing the filtration layers of different materials. In addition to enhancing the water filtration effect of the filter, the filter layer can be taken out and recycled after a certain period of use, and the entire cartridge filter need not be discarded, thereby achieving the purpose of protecting the environment.

It is a perspective view of the cartridge filter of the filter which shows the Example of this invention. It is a disassembled perspective view of the cartridge filter of the filter which shows the Example of this invention. It is sectional drawing of the cartridge filter of the filter which shows the Example of this invention. It is sectional drawing in the use condition of the cartridge filter of the filter which shows the Example of this invention.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view of a cartridge filter of the filter, and FIG. 2 is an exploded perspective view of the cartridge filter of the filter.
As shown in FIGS. 1 and 2, the cartridge filter of the filter of the present invention includes a tube body 1, and an upper lid 2 and a lower lid 3 that are screwed to the tube body 1.
Male screws 11 and 12 are provided at the upper and lower ends of the tube body 1, and filtration layers 13, 14 and 15 of different materials are arranged inside the tube body 1. In the present embodiment, the filtration layers 13, 14, and 15 can be selected from sand and materials that are environmentally friendly and emit far infrared rays, and are suitable for recycling.

The upper lid 2 is provided with a water inlet 21, and the lower lid 3 is provided with a water outlet 31.
Moreover, the recessed fitting tanks 22 and 32 are provided along the circumferential direction on the side wall inner surfaces of the upper lid 2 and the lower lid 3, and different types of filter media 4, 5, and 6 can be fitted into the recessed fitting tanks 22 and 32. it can. In this embodiment, after the filter media 4, 5, 6 are arranged in the concave fitting tanks 22, 32, the C-shaped ring 7 having elasticity is installed in the concave fitting tanks 22, 32, and the filter media 4, 5, 6 is positioned.
Further, the upper lid 2 and the lower lid 3 are provided with female screws 23 and 33 on the periphery of the opening, respectively, and can be screwed into the male screws 11 and 12 of the tube 1.

  As shown in FIG. 3, the recessed fitting tanks 22, 32 provided in the circumferential direction of the upper lid 2 and the lower lid 3 form a slightly large stepped portion on the inner surface of the upper lid 2 and the lower lid 3, and Concave tanks 221 and 321 having a slightly larger diameter are formed on the distal end side. And after arrange | positioning the filter media 4, 5, and 6 in a step part, the C-shaped ring 7 is installed in the concave tanks 221 and 321 (the C-shaped ring 7 is sandwiched and shrunk inside by a tool, the concave tank 221, , After having put it in the position of 321, it is spread again outward and locked to the concave tanks 221, 321), and the filter media 4, 5, 6 are positioned so that the filter media 4, 5, 6 are wobbled And will not fall off.

As shown in FIG. 4, the cartridge filter of the filter of the present invention is used by being incorporated in the filter. When water enters from the water inlet 21 of the upper lid 2, foreign substances in the water are first filtered through the filter media 4, 5, 6, and further bacteria in the water pass through the filter layers 13, 14, 15 of different materials. Filtered to enhance the filtration effect. Further, through the filter media 4, 5, 6 of the lower lid 3, foreign matter of the filter media that may be caused by the filter layers 13, 14, 15 is filtered.
After the use for a certain period of time, the upper lid 2 and the lower lid 3 are removed, the filtration layers 13, 14, 15 in the tube body 1 can be taken out and recycled, and it is not necessary to discard the entire cartridge filter. Can reach.

  The above is for explaining the best embodiment of the present invention, and does not limit the scope of rights of the present invention, and all slight modifications and changes without departing from the gist of the present invention are all within the scope of rights of the present invention. include.
