Description

Technical Field

[0001] The utility model relates to the field of bathtubs, in particular to a detachable bathtub filter mechanism. Background Art

[0002] A bathtub is a plumbing fixture used for bathing or showering, typically found in a home bathroom. Modern bathtubs are mostly made of acrylic or fiberglass, with some also made of ceramic-coated steel. Traditionally, most bathtubs were rectangular. In recent years, with the increasing popularity of acrylic heated bathtubs, bathtubs of various shapes have begun to appear. The most common color is white, though other shades such as pink are also available. Most bathtubs have a drain at the bottom and an overfilling prevention valve at the top. Some bathtubs have the faucet installed on the rim.

[0003] For example, the patent application of our company with authorization announcement number CN220750423U discloses a hot and cold water circulation system and a bathtub thereof, including a circulating water pump, a thermostat and a refrigerator; the water inlet and outlet of the circulating water pump are respectively connected to a return pipe and an outlet pipe, the return pipe is connected to the return water outlet, and a thermostat is also installed on the return pipe, which is a heater for heating the flowing water; a filter is also installed on a section of the return pipe near the return water outlet; two branch water pipes are connected to the outlet pipe through a tee, and the branch water pipes are connected to a water outlet nozzle through a water distributor; a refrigerator is also installed on the outlet pipe.

[0004] The above patented filter is located at the tail end of the bathtub shell. When the inner tank of the filter needs to be cleaned, the inspection door needs to be removed to clean or replace the inner tank of the filter. Moreover, the filter is located inside the inspection door, which is very inconvenient to disassemble.

[0005] Therefore, it is necessary for us to improve such a structure to overcome the above-mentioned defects. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] See also Figure 1-7 , a detachable bathtub filter mechanism, including a filter 4;

[0026] The filter 4 is located inside the bathtub, and the bathtub includes a bathtub liner 1 and a bathtub shell 2. The bathtub liner 1 and the bathtub shell 2 are integrally formed and made of PMMA plastic. The bathtub liner 1 is located inside the bathtub shell 2. The bathtub liner 1 is a stepped shell with a larger top and a smaller bottom, and the top is open. The bathtub shell 2 is a stepped shell with a larger top and a smaller bottom, and the bottom of the bathtub shell 2 is open. The bathtub liner 1 and the bathtub shell 2 are integrally formed. A base 3 is also fixedly installed at the bottom of the bathtub shell 2. The filter 4 includes a filter main shell 401 and a filter main shell 402. The filter element 402 is provided with a main filter housing 401 which is cylindrical in shape and has an open front end. A water inlet pipe 403 is provided at the top of the side of the main filter housing 401. A water outlet pipe 404 is provided at the center of the rear end of the main filter housing 401. A positioning circular pipe 405 is provided at the center of the rear end of the main filter housing 401 and extends forward. The positioning circular pipe 405 is connected to the water outlet pipe 404. At the same time, the front end of the outer wall of the positioning circular pipe 405 is closed toward the center, that is, the front end of the positioning circular pipe 405 is in the shape of a truncated cone, so as to facilitate insertion into the positioning hole 411.

[0027] In this solution, the side of the bathtub shell 2 is provided with an opening adapted for the filter main housing 401 , and the front end of the filter main housing 401 is fixedly and sealedly connected to the bathtub shell 2 ;

[0028] The filter element 402 includes a filter element bracket 406 and a filter screen 407. The filter element bracket 406 includes a base plate 408 and an end cover 409. The base plate 408 and the end cover 409 are fixedly connected by at least four connecting columns 410. The filter screen 407 is cylindrical in shape and fixedly connected to the base plate 408 and the end cover 409.

[0029] In this solution, the filter 407 is composed of a folded metal mesh, thereby increasing the area and thus improving the efficiency of filtration;

[0030] In this embodiment, a positioning hole 411 is provided at the center of the base plate 408 to match the positioning tube 405. An internal thread 412 is provided on the inner wall of the front opening of the filter main housing 401, and an external thread 413 is provided on the outer wall of the end cap 409 to match the internal thread 412.

[0031] At the same time, the front end of the end cover 409 is tilted so as to fit in with the tilted outer wall of the bathtub housing 2, thereby ensuring that the overall structure of the bathtub housing 2 is not obtrusive;

[0032] At the same time, the front end of the end cover 409 is also sunken and provided with a handle groove 414, so as to facilitate the rotation of the filter element 402;

[0033] When this solution is put into use, taking the hot and cold water circulation system and bathtub thereof, which is the subject of our company's application for authorization announcement number CN220750423U, as an example, the filter 4 is installed on a section of the return pipe near the return port. The water inlet pipe 403 of the filter 4 receives water flowing from the return port. The water flows from the return port into the filter 9, is filtered, and then flows through the thermostat through the outlet pipe 404.

[0034] Water enters from the water inlet pipe 403, flows through the surface of the filter screen 407, and the dirt in the water remains on the surface of the filter screen. The filtered water enters the positioning circular pipe 405 through the positioning hole 411 in the center of the cylindrical filter screen 407, and is finally discharged from the water outlet pipe 404.

[0035] When the filter element needs to be cleaned, the filter element can be easily removed from the bathtub by rotating the end cover of the filter element.
