[0002] Daily drinking water filtration is to pass raw water through a filter device before drinking. The filter device has a filter structure and contains filter materials to optimize the water quality. Generally, this type of structure uses a filter cylinder to contain filter materials (such as medical stone, etc.) and is placed in a filter. Although it can complete the filtration process, there are still some potential problems, such as: (1) Since the water flow does not flow through the filter material in sequence, once the water flow is too large and too fast, it cannot be filtered completely; (2) The filter material placed in the filter element is easy to clog the filter or the inlet and outlet, and it is not very convenient to replace the filter material.

DETAILED DESCRIPTION
[0019] In order to more intuitively and completely understand the technical solution of the utility model, the following non-limiting feature description is now provided in conjunction with the accompanying drawings of the utility model: Example
[0020] like Figure 1 — Figure 6 As shown, a filter element with a filter cartridge comprises a filter cartridge 1 and a filter cartridge 2. The filter cartridge 2 is placed in the filter cartridge 1, and the filter cartridge 2 has filter material built in it. Both ends of the filter cartridge 1 are provided with cartridge covers 3 to seal the two ports. The filter cartridge 2 comprises a main body 21 with a top opening and a cover 22 to seal the top opening. The cover 22 can be designed as a butt-jointed structure, that is, the cover 22 is inserted into the port of the main body 21 to form a seal, or designed as a more common rotating combined structure. The detachable design of the cover 22 can facilitate the replacement of the filter material. The upper section of the main body is cylindrical, and the lower part of the upper section of the main body is provided with a plurality of notches 23 around the cylinder. A plurality of filter holes 24 are provided at the bottom of the segment, a step is formed between the lower segment of the main body and the upper segment of the main body, the diameter of the lower segment of the main body is smaller than the diameter of the upper segment of the main body, the lower segment of the main body is concave and its top is the bottom of the upper segment of the main body, and a plurality of notches 25 are provided at the port position of the lower segment of the main body; the top of the cover 22 is concave, and a plurality of filter holes 24 are provided at the bottom of the concave portion, a step is formed between the side wall of the cover 22 and the upper segment of the main body, and the diameter of the side wall segment of the cover is smaller than the diameter of the upper segment of the main body; the lower segment of the main body is engaged with the cartridge cover 3 at one end of the filter cartridge 1, and the cover 22 is engaged with the cartridge cover 3 at the other end of the filter cartridge 1; here, the lower segment of the main body and the upper segment of the main body are of an integrated design.
[0021] The cartridge cover 3 of the filter cartridge 1 includes a top cover 31 and a bottom cover 32 . The top cover 31 is docked with the sealing cover 22 , and the bottom cover 32 is docked with the lower section of the main body. Through holes 33 are provided in the middle of the top cover 31 and the bottom cover 32 .
[0022] The top cover 31 has an annular structure protruding inwardly, which is divided into an inner ring 311 and an outer ring 312. The area surrounded by the inner ring 311 covers the through-port 33. The inner ring 311 is sealed and buckled with the port on the side wall of the cover 22, and the outer ring 312 is sealed and buckled with the port of the filter cartridge 1. The through-port 33 on the top cover 31 is communicated with the filter hole 24 at the bottom of the cover 22; the bottom cover 32 has an annular structure protruding inwardly, which is divided into a groove ring 321 and an outer wall ring 322. The area surrounded by the groove ring 321 covers the through-port 33 on the bottom cover 32. The groove ring 321 has a plurality of grooves 3211 protruding from the inside of the ring to the outside. The inner wall of the groove ring 321 is fitted with the lower section of the main body, the notch 25 of the lower section of the main body is communicated with the groove 3211, and the outer wall ring 322 is sealed and buckled with the port of the filter cartridge 1.
[0023] The filter cartridge 1 comprises an annular grid-shaped frame 11 and a filter screen (not shown) fixed on the frame. This design allows the filter screen to be used for coarse filtering.
[0024] According to this design, the water flow filtering direction of the filter element can be the following three:
[0025] (1) From the opening 33 on the bottom cover 32 through the filter holes 24 on the upper section of the main body, the filter material, the filter holes 24 on the cover 22, to the opening 33 on the top cover 31;
[0026] (2) from the filter screen through the notch 23, the filter material, the filter hole 24 on the cover 31, to the opening 33 on the top cover 31;
[0027] (3) From the opening 33 on the bottom cover 32 through the notch 25 of the lower section of the main body, the groove 3211, the notch 23, the filter material, the filter hole 24 on the cover 22, to the opening 33 on the top cover 31.
[0028] The above three waterways, no matter which one, will greatly meet the requirements of complete filtration, because the water flow will eventually pass through most areas of the filter cartridge 2, and avoid the situation that although the conventional product appears to be equipped with filter material, the water flow only touches the filter material and then flows out quickly, and a relatively complete filtration process cannot be achieved. Example
[0029] like Figure 3 and Figure 4 As shown, the scheme based on the first embodiment remains unchanged, only the setting between the cover 22 and the main body 21 is changed. After the filter material is filled into the main body 21, the cover 22 is sealed with the main body 21 to be integrated and inseparable, usually by welding. When the filter material needs to be replaced, the filter material cartridge 2 can be directly replaced. In actual use, in order to facilitate people to replace, the manufacturer will provide a filter material cartridge 2 with filter material already installed inside as an accessory for replacement, and there is no need to open the filter material cartridge 2 to replace the filter material.
[0030] Of course, the above are only preferred embodiments of the present invention, and the patent scope of the present invention is not limited thereto. All simple modifications and equivalent structural changes made using the description and drawings of the present invention should be included in the patent protection scope of the present invention.
