Technical Field

[0001] This utility model relates to the field of bathroom equipment technology, and in particular to a filter assembly installation structure. Background Technology

[0002] Floor-standing bathtub faucets are a common choice in modern bathrooms, but their post-installation maintenance is often overlooked. Due to their fixed structure, daily disassembly and cleaning become extremely inconvenient once installed. When scale, silt, or other impurities in the pipes cause blockages, users often need to remove the entire faucet from the floor for cleaning, a tedious and time-consuming process.

[0003] Currently available products lack a comprehensive solution to this problem. Some faucets lack a filter at the water inlet, which can easily lead to impurities directly damaging or clogging the valve core and showerhead. Others have built-in filters, but their design often makes them difficult for users to clean themselves. The filters become clogged due to lack of cleaning over time, ultimately reducing water flow and severely impacting the comfort and experience of showering. Utility Model Content

Detailed Implementation

[0018] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0019] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0020] like Figures 1-9 As shown, this embodiment provides a filter assembly installation structure 1, which can be used in a water system including a faucet, comprising: a pre-embedded body 10, a pre-embedded box 20, and a filter assembly 30. The pre-embedded body 10 is provided with a first fluid channel 16 and a second fluid channel 17. The first fluid channel 16 has a first inlet 12 and a first outlet 14 on the pre-embedded body 10, and the second fluid channel 17 has a second inlet 13 and a second outlet 15 on the pre-embedded body 10. Figure 1 , Figure 3 As shown, the first fluid channel 16 can be configured as a cold water channel with a cold water inlet direction C; the second fluid channel 17 can be configured as a hot water channel with a hot water inlet direction H. Of course, in some other embodiments, the embedded body 10 may also be provided with more or fewer fluid channels, and there is no limitation on the number of fluid channels of the embedded body 10 and the type of fluid flowing through them.

[0021] The embedded body 10 also has two filter assembly mounting slots 18, which are respectively connected to the first fluid channel 16 and the second fluid channel 17, and form openings on the outer surface of the embedded body 10. The filter assembly mounting slots 18 are suitable for detachable installation of the filter assembly 30, positioning the filter structure of the filter assembly 30 in the first fluid channel 16 and the second fluid channel 17, thereby filtering the fluid. Because the filter assembly 30 is detachably installed on the embedded body 10 through the filter assembly mounting slots 18, it is easy to install, disassemble, and clean, preventing the valve core or filter screen from becoming clogged due to impurities in the water, which could lead to reduced flow or damage to the valve core. Therefore, this structure is adaptable to the disassembly and installation of the filter assembly under wall-embedded conditions.

[0022] The filter assembly 30 includes a connector 31, a first seal 32, a filter screen 33, and a second seal 34. The connector 31 is detachably installed in the filter assembly mounting slot 18, and the filter screen 33 is connected to the connector 31, thereby positioning the filter screen 33 in the first fluid channel 16 or the second fluid channel 17. The filter assembly mounting slot 18 has an internal thread 19. The connector 31 has a first end and a second end in opposite directions. The first end of the connector 31 has an external thread 311, which is adapted to be screwed into the internal thread 19, thereby connecting the connector 31 to the filter assembly mounting slot 18. The second end of the connector 31 has a tool interface 312, the shape of which is designed to receive an operating tool, such as a hex wrench, so that the connector 31 can be screwed into the filter assembly mounting slot 18 using this operating tool. When the flow rate of the faucet decreases due to blockage, the connector 31 can be disassembled with a hex wrench, and the filter screen 33 can be taken out and cleaned together. After cleaning, the connector 31 and the filter screen 33 can be reinstalled with a hex wrench and the connector 31 can be tightened.

[0023] When connector 31 is connected to the filter assembly mounting slot 18, filter 33 is positioned in the first fluid channel 16 or the second fluid channel 17. In this embodiment, the connector 31 and filter 33 are connected by a snap-fit ​​structure. Specifically, a snap-fit ​​slot 313 is provided at the first end of connector 31, i.e., the lower end of connector 31. A snap-fit ​​flange 314 extends inward from the edge of the snap-fit ​​slot 313. A snap-fit ​​tooth 331 is provided at the top of filter 33. The snap-fit ​​tooth 331 has a groove 332. The snap-fit ​​tooth 331 engages with the snap-fit ​​slot 313, and the snap-fit ​​flange 314 engages with the groove 332, thereby forming a snap-fit ​​structure between connector 31 and filter 33. In this embodiment, multiple snap-fit ​​teeth 331 are arranged in a ring, and the snap-fit ​​flange 314 is also ring-shaped, but this is not a limitation. In some other embodiments, the snap-fit ​​teeth 331 may also be a single annular structure. Alternatively, in some other embodiments, the shape or arrangement of the snap-fit ​​teeth 331 may be square, polygonal, etc., which will not be listed here, and the snap-fit ​​flange 314 may have a corresponding mating shape.

[0024] Both the snap-fit ​​teeth 331 and the snap-fit ​​flange 314 are chamfered to facilitate the snap-fit ​​teeth 331 into the snap-fit ​​groove 313. The connector 31 has a first sealing groove 315 at the root of the external thread 311. The first sealing groove 315 is used to install a first sealing element 32, thereby forming a seal between the connector 31 and the embedded body 10. The first sealing element 32 is, for example, an O-ring.

[0025] Reference Figures 5-6The filter screen 33 is a hollow cylindrical structure, including a support frame 333 and a filter screen material 334. The filter screen material 334 is supported and installed on the support frame 333. The filter screen material 334 is arranged in a C-shape around the outer periphery of part of the support frame 333, thereby forming a filter screen opening 339. The filter screen opening 339 of the filter screen 33 is positioned to face the direction of fluid inflow. This structure is more conducive to capturing impurities in the fluid in the filter screen and can accommodate more impurities, thereby improving the service life of the filter screen.

[0026] The support frame 333 includes a first support member 338, a second support member 335, and a strip support member 336 connecting the first support member 338 and the second support member 335. The first support member 338 and the second support member 335 have a circular cross-sectional shape. Two strip support members 336 can be provided. The two ends of the filter material 334 in the lateral direction are connected to the two strip support members 336, and the two ends of the filter material 334 in the longitudinal direction are connected to the first support member 338 and the second support member 335 respectively, so that the filter material 334 is arranged in a C-shape around the outer periphery of part of the support frame 333. Of course, as those skilled in the art will readily understand, the number of strip support members 336 can be set to more or less. For example, more than two strip support members 336 can be provided to enhance the support effect on the filter material 334. Alternatively, in some embodiments, if the filter material 334 has sufficient structural strength, the strip support 336 can be omitted; that is, the filter material 334 is connected to the first support 338 and the second support 335 respectively through its own structure. In some embodiments, the filter material 334 and the support frame 333 can be integrally formed.

[0027] The filter material 334 has multiple horizontally arranged openings in a vertical direction, which are used to filter impurities. Furthermore, the gap size of the horizontal openings can be adjusted according to specific filtration requirements to adapt to the filtration needs of different impurities, thereby improving the adaptability of the filter material 334.

[0028] Reference Figures 3-6 The pre-embedded body 10 has a positioning shoulder 11 in the filter assembly mounting slot 18. The diameter of the first support member 338 is larger than the diameter of the second support member 335, so that the second support member 335 and the filter material 334 can pass through the positioning shoulder 11, while the first support member 338 is limited by the positioning shoulder 11 and is axially positioned between the positioning shoulder 11 and the connector 31. The filter screen 33 may also have a radially protruding radial positioning protrusion (not shown), and the filter assembly mounting slot 18 may have a positioning groove (not shown). The radial positioning protrusion can cooperate with the positioning groove in the filter assembly mounting slot 18 to achieve the radial orientation of the filter screen 33, so that the filter opening 339 of the filter screen 33 is positioned to face the direction of fluid inflow.

[0029] The first support member 338 is connected to the snap-fit ​​teeth 331. The snap-fit ​​teeth 331 and the strip support member 336 are connected to opposite ends of the first support member 338. The second support member 335 has a second sealing groove 337 circumferentially provided. The second sealing groove 337 is used to install a second sealing member 34, thereby forming a seal between the filter screen 33 and the embedded body 10. The second sealing member 34 is, for example, an O-ring.

[0030] An embedded box 20 may be provided to cover the embedded body 10 to provide protection for the embedded body 10. The embedded box 20 includes a box body 21 and a connecting flange 22, which is used to connect to the embedded body 10 by screws.

[0031] Reference Figure 1 , Figure 8 and Figure 9 The first outlet 14 and the second outlet 15 can be fitted with pipe fittings 60, allowing hot water pipes and cold water pipes to be laid within the pipe fittings 60. A decorative cover 70 can also be fitted onto the pipe fitting 60, covering the surface of the embedded body 10 and the embedded box 20 for aesthetic decoration. The filter assembly 30 can be disassembled using a hex wrench by lifting the decorative cover 70 upwards; the disassembly operation is simple and convenient, allowing for quick disassembly and cleaning of the filter assembly 30.

[0032] Reference Figure 1 In addition, plugs 50 and sealing rings 51 can be selectively connected to the first outlet 14 and the second outlet 15 to selectively enable or disable the first fluid channel 16 or the second fluid channel 17.

[0033] Reference Figures 1-3 A flow regulation component 40 is also provided on the pre-embedded body 10. The flow regulation component 40 can be used to regulate the flow rate of the fluid flowing through the first fluid channel 16 and the second fluid channel 17, which can quickly realize the adjustment of the water flow in the pipeline and improve the adjustability of the pre-embedded body 10 components.

[0034] The flow regulation assembly 40 includes an adjustment knob 41 and a flow regulation ball 42. The flow regulation ball 42 is installed in the first fluid channel 16 and the second fluid channel 17, and the flow regulation ball 42 has an adjustment channel 421. The adjustment knob 41 is rotatably installed in the pre-embedded body 10, and one end of it is connected to the flow regulation ball 42. For example, the straight end of the adjustment knob 41 cooperates with the slot of the flow regulation ball 42, so that the rotation of the adjustment knob 41 can drive the flow regulation ball 42 to rotate to regulate the fluid flow rate. The rotation of the flow regulation ball 42 causes the adjustment channel 421 to be at least partially blocked by the inner wall of the pre-embedded body 10, thereby changing the cross-sectional area of ​​the adjustment channel 421 to regulate the flow rate of the fluid flowing through the first fluid channel 16 and the second fluid channel 17. By lifting the decorative cover 70, the adjustment knob 41 can be rotated with a tool to adjust the water flow rate. The adjustment operation is simple and convenient, and the water flow rate in the pipeline can be quickly adjusted.
