A water inlet slot 2 and a water outlet through-hole 3 are fixed at both ends of the bottom surface of the filter cartridge shell. At least two partitions 4 are integrally formed in the inner cavity of the filter cartridge shell, dividing the inner cavity into a water inlet filtration chamber 5, a middle filtration chamber 6, and a water outlet filtration chamber 7. In this embodiment, the water inlet slot can be a round hole, a strip-shaped slot, or a square hole, while the water outlet through-hole is a round hole.

[0029] Furthermore, the water inlet hole is located on the bottom wall of the water inlet filtration chamber, and the water outlet hole is located on the bottom wall of the water outlet filtration chamber; at the same time, the water inlet filtration chamber, the middle filtration chamber, and the water outlet filtration chamber are all filled with activated carbon filter layers; a filter cotton column 9 is provided in the water outlet filtration chamber, and the bottom end of the filter cotton column is inserted into the water outlet hole for positioning; the activated carbon filter layer in the water outlet filtration chamber covers the outside of the filter cotton column.

[0030] Furthermore, a cover 10 is snapped onto the top of the filter core shell, and a number of water-passing mesh sheets 11, corresponding to the positions of the partitions, are fixed to the bottom surface of the cover. The cover is fastened to the top surface of the filter core shell, and the bottom edges of the water-passing mesh sheets are attached to the top surface of the partitions. Water flows through the inlet filter chamber, intermediate filter chamber, and outlet filter chamber via the water-passing mesh sheets at the top of the partitions. These water-passing mesh sheets ensure the effectiveness of water flow and prevent the loss of the activated carbon filter layer, thereby improving filtration effectiveness.

[0031] In this embodiment, a vertical guide groove 12 is provided on the symmetrical inner wall of the filter core shell, and the vertical guide groove is located in the middle filter chamber; a guide plate 13 is fixed on the bottom surface of the shell; the symmetrical edges of the guide plate are inserted into the vertical guide groove for limiting; water in the middle filter chamber flows through the bottom of the guide plate.
