The cloth body has a first inner tube cover system coupled to the inner tube body and provided with a water inlet hole side, and the second inner tube cover body is disposed on the other side of the inner tube body, and the surface layer filter body is sleeved outside the inner tube body, The inner tube of the filter element is placed in a filter outer tube body, and a water inlet is arranged on one side of the outer tube body of the filter element, and a water outlet is arranged on the other side of the outer tube body of the filter element, and the water inlet of the outer tube body of the filter element is relatively In the first inner tube cover, and the water outlet of the outer tube of the filter element is opposite to the second inner tube cover The elastic retaining ring provided by the first inner tube cover body and the second inner tube cover ring groove are tightly attached to the inner wall of the filter inner tube group, and the water enters through the outer core of the filter element. After the water inlet is introduced and filled with the space between the inner wall of the outer tube of the filter element and the outer wall of the inner tube of the inner tube group of the filter element, the guide tube provided by the inner tube body of the inner tube group of the filter element is matched with the surface layer filter body, and the water guide is introduced. The inner pipe body is provided with a water guiding hole and introduced therein, and then filtered by the filter material provided in the inner pipe body, and the water outlet is provided by the second inner pipe cover body, and the water outlet is led to the outer pipe body to be discharged. It can effectively improve the filtration efficiency and prevent the filter material from coming out, so as to achieve the filtering effect and the good stability of the built-in filter material.

In order to provide the Applicant with a better understanding of the structure, features and other objects of the present invention, the following detailed description is provided with the following detailed description, but the embodiments illustrated in the drawings are for illustrative purposes. It is not the only restriction on patent applications.

Please refer to the figures 1 to 3, which are schematic diagrams showing the improved three-dimensional combined state, three-dimensional decomposition state and side-viewing state of the filter element structure, which includes: a filter inner tube group 10, and the filter inner tube group 10 is provided. There is an inner tube body 11, a first inner tube cover body 12, a second inner tube cover body 13 and a surface layer filter body 14, and the outer surface of the inner tube body 11 is provided with a plurality of ring protrusions 110 and a plurality of ring-shaped bumps. The plurality of guide grooves 111 are formed at intervals of one end, and the outer surface of one end of the inner tube body 11 is provided with a plurality of water inlet holes 112, and the outer ring of the first inner tube cover 12 is provided with a plurality of positioning top holding protrusions 120, and the second inner portion The outer ring of the tube cover 13 is provided with a ring groove 130, and the ring groove 130 is combined with a resilient water stop ring 130A, and the surface filter body 14 is a filter cotton body or a filter cloth body. The second inner tube cover body 13 is penetrated through the front surface. A plurality of water outlets 131 are provided, the first inner tube cover 12 is coupled to the inner tube body 11 and provided with the water inlet hole 112 side, and the second inner tube cover 13 is disposed on the other side of the inner tube body 11 and the surface layer is filtered.
