[0020] The following specific implementation manner will further illustrate the present utility model in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION

[0021] In order to facilitate the understanding of the utility model, the utility model will be described more comprehensively with reference to the relevant drawings. Several embodiments of the utility model are given in the drawings. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and comprehensive.

[0022] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0024] See also Figure 1 and Figure 2 A combined bathtub filter element provided by an embodiment of the utility model includes an external thread base 10, a frame 20 arranged at the upper end of the external thread base 10, an internal thread top cover 30 arranged at the upper end of the frame 20, and a mesh cloth 40 sleeved on the outer periphery of the frame 20. The surface of the frame 20 is provided with a plurality of water through holes 21, the upper end of the internal thread top cover 30 is provided with an internal thread hole 31, and the lower end of the external thread base 10 is provided with an external thread connecting column 11, and the external thread connecting column 11 cooperates with the internal thread hole 31.

[0025] In the above-mentioned combined bathtub filter element, two detachable bathtub filters can be connected end to end through the inner thread hole 31 and the outer thread connecting column 11, so that multiple detachable bathtub filters can be used in combination, which can increase the filtering accuracy and improve the user experience.

[0026] In one embodiment of the present invention, the mesh 40 is a nylon mesh, and the use of the mixed fluidized bed filler 50 improves the filtering accuracy and water inlet flow rate of the combined bathtub filter element for coarse particles and chemicals in water.

[0027] In one embodiment of the utility model, a sealing cover 60 is further included on the upper end of the inner thread top cover 30 so as to close the filter element during bathing so that the bathtub can store water normally. When bathing is completed, the sealing cover 60 only needs to be removed to allow water to flow into the filter element for filtration.

[0028] In one embodiment of the present invention, a handle structure 70 is provided at the upper end of the sealing cover 60 to facilitate holding the sealing cover 60 .

[0029] In one embodiment of the present invention, the edge of the external screw base 10 is provided with an upwardly extending flange 12 , and the outer side of the lower end of the frame 20 abuts against the inner side of the flange 12 to limit the upper and lower ends of the mesh 40 .

[0030] In one embodiment of the present invention, please refer to Figure 3 and Figure 4, and also includes a fluidized bed filler 50 arranged in the skeleton 20. The addition of nitrifying bacteria to the fluidized bed filler 50 can effectively remove chemical substances and microorganisms in the water, such as nitrogen, dissolved oxygen, and microorganisms caused by human body oil secretion, so as to further improve the filtering accuracy of the combined bathtub filter element.
