The utility model provides a filter element of a filter device, comprising: a filter inner cylinder, a filter outer cylinder and an end cover; the filter inner cylinder has a central hole; the filter outer cylinder is set outside the filter inner cylinder, and the filter inner cylinder and the filter outer cylinder are coaxial setting; there is a filtering gap between the filtering inner cylinder and the filtering outer cylinder; the end caps are arranged at the two ends of the filtering inner cylinder and the filtering outer cylinder.

Furthermore, the utility model provides a filter element of a filter device, which may also have the following feature: the filter material with the function of filling the filter space.

In addition, the utility model provides a filtering device, including: the above-mentioned filter element, a filter housing assembly, a water inlet and a water outlet; wherein, the filter housing assembly is arranged coaxially with the filter element; the water inlet is arranged between the filter housing assembly and the filter outer cylinder ; The water outlet communicates with the central hole of the filter inner cylinder.

Further, the utility model provides a filter device, which may also have the following feature: it also includes a sealing ring, which is arranged between the filter element and the filter housing.

Further, the utility model provides a filter device, which may also have the following feature: the filter housing assembly includes a filter housing and a filter housing cover.

Beneficial Effects of Utility Models

The utility model provides a filter element, because it has a filter inner cylinder and a filter outer cylinder arranged coaxially, the water to be filtered enters the filter gap from the outside of the filter outer cylinder, and then enters the filter inner cylinder, and passes through After being filtered by the filter inner cylinder, it enters the central hole of the filter inner cylinder and flows out to complete the filtration process; one filter element completes the multi-channel filtration process of the traditional filter element.

The utility model provides a filtering device. Because it has a filter core for simultaneous filtering in multiple processes, it is necessary to enter the filtered water from the water inlet. After being filtered by the filter core, the entire filtering process is directly completed, and there is no redundant connecting pipe inside the filtering device.

The filter device provided by the utility model is only 1/3 of the size of the traditional filter device, light in weight, and has the same filtering effect. More coaxial filter cartridges can also be installed. The more filtering processes, the more the volume is reduced, and it is practical and convenient. , Mobile and flexible.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.

Fig. 3 is a structural schematic diagram of the filter element of the present invention.

Fig. 4 is a cross-sectional view of the filter element of the present invention.

As shown in FIGS. 3 and 4 , the filter element 100 of the filter device includes: an inner filter cylinder 10 , an outer filter cylinder 20 , an upper end cover 41 and a lower end cover 42 .

The filter inner cylinder 10 has a central hole, and the filter inner cylinder 10 can be made of rear activated carbon material. The filtering outer cylinder 20 can be made of pre-activated carbon material. The filtering outer cylinder 20 is sleeved outside the filtering inner cylinder 10, and the filtering inner cylinder 10 and the filtering outer cylinder 20 are arranged coaxially.

There is a filter gap 30 between the filter inner cylinder 10 and the filter outer cylinder 20 . According to the water quality to be filtered, corresponding functional filter materials can be filled in the filter gap 30 .

The upper end cover 41 is arranged on one end of the filter inner cylinder and the filter outer cylinder, and the lower end cover 42 is arranged on the other end of the filter inner cylinder and the filter outer cylinder.

The water that needs to be filtered enters the filter gap 30 from the outside of the filter outer cylinder through the filtration of the activated carbon in front of the filter outer cylinder. Then enter the filter inner cylinder, after passing through the filter inner cylinder with activated carbon, it enters the central hole of the filter inner cylinder and then flows out to complete the filtration process.

The filter inner cylinder and the filter outer cylinder can also be filter materials of other materials. The filter cavities may also need to be filled with corresponding filter material. If the liquid to be filtered is seriously polluted, a pre-filter cartridge can be installed outside the filter outer cylinder, and the filter inner cylinder, filter inner cylinder and pre-filter cartridge are coaxially arranged, so that the filtered liquid will have one more filtration process. ,
