[0024] In order to make the purpose, technical solutions and advantages of this application clearer, the application is further described in detail below in conjunction with the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain this application and are not used to limit this application.

[0025] With the continuous advancement of technology and people's increasing demands for a better quality of life, massage bathtubs have become increasingly popular. Existing massage bathtubs are typically equipped with a filter to filter the water discharged from the bathtub. However, these bathtubs often use open or pressure filters, which make it difficult to disassemble and install the filter element and the tub.

[0026] This embodiment provides a closed filter, which can improve the convenience of disassembly and assembly of the filter element and the cylinder.

[0027] See also Figure 1 In this embodiment, a closed filter includes a cylinder 10, a filter element 20 and an end cover 30; wherein, the cylinder 10 has a water inlet 14 and a water outlet 16, and a fixing member 12 is provided on the outside of the cylinder 10; the filter element 20 is inserted into the inside of the cylinder 10, and is used to filter the water flowing into the water inlet 14 and discharge it through the water outlet 16; the end cover 30 is screwed into the cylinder 10, and is used to press the filter element 20 to the inside of the cylinder 10, and the cylinder wall is clamped between the end cover 30 and the fixing member 12.

[0028] By adopting the technical solution of this embodiment, the end cover 30 is screwed together with the cylinder body 10, which can fix the filter element 20 and the cylinder body 10 at the same time. By removing the end cover 30, it is convenient to remove the cylinder body 10 from the cylinder wall, and at the same time, it is convenient to remove the filter element 20 from the inside of the cylinder body 10, thereby improving the convenience of disassembly and assembly of the cylinder body 10 and the filter element 20.

[0029] In this embodiment, the cylinder 10 is constructed into a cylindrical shape with both ends open, and a lower base 13 is fixedly connected to the lower end of the cylinder 10. The lower base 13 is sleeved on the outside of the cylinder 10, and the lower base 13 has a closed end face. The lower base 13 is coaxially arranged with the cylinder 10, and the lower base 13 closes the lower end of the cylinder 10. As an example, the lower base 13 is bonded and fixed to the cylinder 10.

[0030] In addition, the lower base 13 is fixedly connected to a water inlet 14, a support member 15 and a water outlet 16, wherein the support member 15 is coaxially arranged with the lower base 13, and the lower end of the support member 15 is fixedly connected to the end face of the lower base 13, and the support member 15 extends to the interior of the cylinder 10 and is coaxially arranged with the cylinder 10. Specifically, the upper end of the support member 15 is inserted into the lower end of the return water channel 21 of the filter element 20, and the support member 15 supports the filter element 20 and guides the water in the return water channel 21 to the water outlet 16 for discharge.

[0031] In addition, the water outlet 16 is connected to the support member 15, and the axis of the water outlet 16 is perpendicular to the axis of the support member 15. The water inlet 14 and the water outlet 16 are respectively placed on the left and right sides of the support member 15, and the water inlet 14 and the water outlet 16 are coaxially arranged. There is a gap between the inner end of the water inlet 14 and the support member 15. The water flowing in from the water inlet 14 flows into the inner cavity of the cylinder 10 outside the filter element 20 through the gap. After the water passes through the filter element 20 and completes filtration, it flows into the return water channel 21, and is finally discharged through the support member 15 and the water outlet 16 in sequence.

[0032] In this embodiment, an upper base 11 is fixedly connected to the upper end of the cylinder 10, and the upper base 11 is sleeved on the outside of the cylinder 10. The upper base 11 and the cylinder 10 are coaxially arranged. The fixing piece 12 is screwed onto the outside of the upper base 11, and the end cover 30 is screwed onto the inside of the upper base 11. The end cover 30 closes the upper end of the cylinder 10. The positioning column 31 and the end cover 30 are integrally formed. The positioning column 31 and the end cover 30 are coaxially arranged. The positioning column 31 is set on the inner surface of the end cover 30, and the positioning column 31 extends into the interior of the cylinder 10. Specifically, the lower end of the positioning column 31 is inserted into the upper end of the return channel 21 of the filter element 20 and closes the upper end of the return channel 21. In order to improve the stability of the filter element 20, an annular first step 311 is provided on the positioning column 31, and the first step 311 abuts against the upper end surface of the filter element 20.

[0033] It should be noted that the end cover 30 has an outer edge extending outward, and a clamping space for clamping the cylinder wall is formed between the outer edge and the fixing member 12 . The cylinder wall is clamped between the fixing member 12 and the end cover 30 .

[0034] It should be understood that when the end cover 30 is screwed into the interior of the cylinder 10, the filter element 20 can be clamped and fixed between the positioning column 21 and the support member 15 by utilizing the corresponding arrangement of the positioning column 31 and the support member 15. At the same time, due to the reduction of the axial distance between the fixing member 12 and the end cover 30, the cylinder wall can be clamped between the lock nut 12 and the end cover 30.

[0035] When in use, first drill a hole for fixing at a designated position on the bathtub surface, then use the clamping action of the fixing parts and the end cover to fix the closed filter on the bathtub surface, then connect the water inlet to the return device of the bathtub, and the water outlet to the water pump. Water flows into the cylinder from the water inlet, and the water flows into the cavity between the entire cylinder and the filter element. Under the action of the suction force of the water pump, the water passes through the filter element and enters the return water channel in the middle. After the water passes through the filter element, the impurities in the water will remain on the filter element, and then the clean water enters the water pump from the water outlet, thus completing the entire filtration process.

[0036] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
