Description

Technical Field

[0001] This utility model relates to the field of bathroom product technology, specifically to a concealed water outlet device. Background Technology

[0002] Currently, concealed water outlet devices commonly suffer from pre-embedding depth issues: when the main control valve body is embedded at different depths, the rigidly connected valve core assembly causes inconsistent positions of the water distribution handle from the wall, affecting both appearance and ease of operation. Users must adjust the handle position by threading or cutting the valve core rod, a complex and time-consuming process. Existing technologies simplify installation with integrated covers, but still rely on rigid piping and adjustable inner covers to compensate for pre-embedding errors, failing to resolve the handle positioning problem caused by differences in pre-embedding depth. Therefore, there is an urgent need for a concealed water outlet device that can adapt to different pre-embedding depths and eliminates the need for handle adjustment. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned defects or problems in the background technology and provide a concealed water outlet device that compensates for the difference in pre-buried depth through flexible pipelines and eliminates the influence of pre-buried depth error on the positioning of the water distribution handle by utilizing the deformation characteristics of the flexible hose, thereby achieving convenient installation.

[0004] To achieve the above objectives, the various embodiments of this utility model adopt the following technical solutions, but are not limited to the following solutions:

[0005] The first technical solution relates to a concealed water outlet device, comprising: a water distribution component, including a base, a water distribution valve disposed on the base, and a water distribution handle assembled on the water distribution valve; the base is adapted to be fixed to the mounting surface so that the relative position of the water distribution component and the mounting surface is fixed; a water passage body, including a concealed housing, a temperature control valve installed in the concealed housing, and a water outlet connector protruding from the surface of the concealed housing; a cavity is reserved in the concealed housing; a flexible pipeline, including a first flexible hose and a second flexible hose, wherein the first water inlet of the water distribution valve is connected to the mixed water outlet of the temperature control valve through the first flexible hose, and the first water outlet of the water distribution valve is connected to the water outlet connector through the second flexible hose; the cavity accommodates the bending movement of the first flexible hose and the second flexible hose.

[0006] The second technical solution is based on the first technical solution, wherein when the pre-embedded depth of the concealed shell changes, the deformation of the flexible pipeline in the cavity compensates for the depth difference.

[0007] The third technical solution is based on the first technical solution, wherein the joint of the flexible pipeline is positioned at the interface of the water distribution valve or the temperature control valve by a snap ring.

[0008] The fourth technical solution is based on the third technical solution, wherein the lengths of the first hose and the second hose are suitable for being pulled outside the mounting platform so that the retaining ring is engaged with the water distribution valve interface.

[0009] The fifth technical solution is based on the first technical solution, wherein the volume of the cavity is greater than the space required for the minimum bending radius of the first and second hoses.

[0010] The sixth technical solution is based on the first technical solution, wherein the base is driven through the mounting platform by long screws and locked to the concealed housing.

[0011] The seventh technical solution is based on the sixth technical solution, wherein the concealed housing consists of a detachable upper cover and a lower cover, and the lower cover is provided with fixing holes for long screws to pass through.

[0012] The eighth technical solution is based on the first technical solution, wherein the water distribution valve includes a water distribution valve body and a valve core, the valve core is locked to the water distribution valve body by a nut, and the water distribution handle is fixed to the valve core rod.

[0013] The ninth technical solution is based on the first technical solution, and further includes a decorative cover plate, which is fixed to the base and covers the outer side of the mounting surface.

[0014] The tenth technical solution is based on the ninth technical solution, and includes an adjusting handwheel, which protrudes from the decorative cover plate and is connected to the anti-rotation valve core of the temperature control valve.

[0015] As can be seen from the above description of the various embodiments of the present utility model, compared with the prior art, the various embodiments of the present utility model have the following beneficial effects:

[0016] In the first technical solution and related embodiments, a flexible pipeline connection system is adopted to eliminate the influence of differences in the pre-embedded depth of the concealed housing on the positioning of control components such as the water distribution handle by utilizing the deformation characteristics of the flexible hose. Specifically, the water distribution component is rigidly fixed to the mounting platform via a base, keeping the height of the water distribution handle fixed to the mounting platform and unaffected by changes in the pre-embedded depth of the concealed housing, thus eliminating the need for secondary adjustment of the water distribution handle. Replacing the rigid pipeline with a flexible pipeline eliminates the stringent requirements for positioning accuracy and simplifies the installation process. A cavity is provided within the concealed housing of the water-passing body to accommodate the bending and movement of the flexible hose as its depth changes, ensuring unobstructed water flow at different pre-embedded depths and achieving adaptive compensation for pre-embedded errors.

[0017] In the second technical solution and related embodiments, the deformation characteristics of the flexible hose compensate for different pre-embedded depths of the concealed housing, adapting to various installation scenarios. This design eliminates the need to cut the valve core rod or adjust the length via threads, improving the product's versatility and installation efficiency.

[0018] In the third technical solution and related embodiments, the hose interface is mechanically locked to the valve body interface by a snap ring. The snap ring provides a reliable axial limiting force, effectively preventing the hose from falling off due to water pressure impact, realizing an integrated anti-detachment and sealing design, and ensuring the stability of the water circuit connection.

[0019] In the fourth technical solution and related embodiments, the hose length is designed to be able to be pulled out of the mounting platform for snap ring assembly, which makes it easier for construction personnel to complete the snap ring connection operation in open space, avoids working in narrow concealed housing, reduces installation difficulty and improves construction efficiency.

[0020] In the fifth technical solution and related embodiments, the cavity volume is designed to be larger than the space required for the minimum bending radius of the hose, ensuring that the hose maintains a safe bending arc when the depth changes, eliminating the risk of water blockage caused by excessive bending, and ensuring smooth water flow.

[0021] In the sixth technical solution and related embodiments, the base is rigidly locked to the concealed shell by long screws. The long screw structure can adapt to changes in the pre-embedded depth within a certain range, while strengthening the overall stability of the water distribution component and avoiding loosening due to vibration or water pressure impact.

[0022] In the seventh technical solution and related embodiments, the concealed housing adopts a detachable split design, which facilitates the pre-installation and subsequent maintenance of the temperature control valve and flexible pipeline, and improves the maintainability of the product.

[0023] In the eighth technical solution and related embodiments, the valve core is mechanically locked to the water distribution valve body by a nut. The nut provides reliable anti-loosening protection to prevent the valve core from shifting under the impact of water flow.

[0024] In the ninth technical solution and related embodiments, the decorative cover plate is fixed to the base and covers the mounting surface, effectively hiding the base and structural components such as screws, and improving the overall appearance and aesthetics of the product.

[0025] In the tenth technical solution and related embodiments, the adjustment handwheel and decorative cover are integrated, allowing users to directly adjust the water temperature through the surface of the decorative cover, making operation convenient. Attached Figure Description

[0045] In the claims, description and accompanying drawings of this utility model, the terms "comprising", "having", and variations thereof are used to mean "including but not limited to".

[0046] See Figures 1 to 12 ,like Figure 1 As shown, a concealed water outlet device includes a water distribution component, a water passage body, a flexible pipeline, a decorative cover plate 9, and an adjusting handwheel 10.

[0047] Water distribution components, such as Figure 2 As shown, it includes a base 1, a water distribution valve 2, and a water distribution handle 3. The water distribution valve 2 is assembled on the base 1, and the water distribution handle 3 is assembled on the water distribution valve 2.

[0048] The base 1 has a clearance space on its surface for the water distribution valve 2 to pass through, and is fixed to the bottom of the base 1 by the first screw 16.

[0049] like Figure 8 and Figure 9As shown, the base 1 is adapted to be fixed to the mounting platform 100 to fix the relative position of the water distribution component and the mounting platform 100. Specifically, one side of the base 1 is flush against the mounting platform 100. The base 1 is secured to the water-passing body by a long screw 12 passing through the mounting platform 100. The structure of the long screw 12 can adapt to changes in the pre-embedded depth within a certain range, while enhancing the overall stability of the water distribution component and preventing loosening due to vibration or water pressure impact.

[0050] Water distribution valve 2, such as Figure 2 As shown, it includes a water distribution valve 2 body and a valve core 22. The valve core 22 is locked inside the water distribution valve 2 body by a nut 24. The nut 24 provides anti-loosening protection to prevent the valve core 22 from shifting under the impact of water flow.

[0051] The water distribution handle 3 is a push-button handle suitable for pressing operation. The water distribution handle 3 is fixed to the top rod of the valve core 22. Specifically, the water distribution handle 3 has a mounting hole 31 for the valve core 22 rod to enter, and the surface of the valve core 22 rod has a positioning protrusion 27. The second screw 17 passes through the side of the mounting hole 31 to lock and abut against the surface of the valve rod to prevent the positioning protrusion 27 from retracting.

[0052] like Figure 8 and Figure 9 As shown, the water distribution handle 3 is fixed to the water distribution valve 2 and protrudes from the surface of the base 1. Specifically, the water distribution handle 3 protrudes from the mounting platform 100 for user operation. Since the position of the base 1 is fixed, the height of the water distribution handle 3 relative to the mounting platform 100 is also fixed, avoiding changes in handle height due to errors in the pre-embedded depth of the water-passing body.

[0053] The main body of the water flow, such as Figure 1 and Figure 3 As shown, it includes a concealed housing 4, a temperature control valve 5, and a water outlet connector 6.

[0054] The concealed housing 4 consists of a detachable upper cover 41 and a lower cover 42. The lower cover 42 has fixing holes for long screws 12 to pass through. The split design of the concealed housing 4 facilitates the pre-installation and subsequent maintenance of the temperature control valve 5 and the flexible tubing. A pre-reserved cavity 43 is provided inside the concealed housing 4 to accommodate the bending and movement of the flexible tubing. The pre-reserved cavity 43 is located in the lower cover 42.

[0055] Thermostatic valve 5 is pre-installed inside concealed housing 4, and water outlet connector 6 protrudes from the surface of concealed housing 4. For example... Figure 3 As shown, specifically, the inlets at the upper and lower ends of the thermostatic valve 5 are a cold water inlet 51 and a hot water inlet 52, respectively, and the outlet forms a mixed water outlet 53. The upper inlet extends into the upper cover 41 of the concealed housing 4, and the lower inlet extends into the lower cover 42 of the concealed housing 4.

[0056] The water outlet connector 6 protrudes from the surface of the concealed housing 4 and is threadedly connected to the screw connection 44 protruding from the surface of the upper cover 41, connecting to external water outlet components (such as shower heads, faucets, etc.).

[0057] like Figure 1 As shown, the base 1 is inserted through the mounting platform 100 by a long screw 12 and locked to the concealed housing 4. A sealing gasket 15 is provided between the base 1 and the concealed housing 4 to prevent water leakage.

[0058] Flexible pipelines, such as Figure 3 , Figures 5 to 7 As shown, it includes a first hose 7 and a second hose 8.

[0059] First hose 7, as Figure 7 and Figure 10 As shown, it connects the first inlet 25 of the water distribution valve 2 body to the mixed water outlet 53 of the temperature control valve 5.

[0060] Second hose 8, such as Figure 7 and Figure 11 As shown, the first outlet 26 of the water distribution valve 2 body is connected to the water outlet connector 6.

[0061] like Figure 5 and Figure 7 As shown, specifically, the first hose 7 and the second hose 8 are flexible corrugated pipes or rubber hoses, with connectors at both ends. The connectors are positioned at the interface of the water distribution valve 2 or the temperature control valve 5 by snap rings. The connectors have annular grooves, and the snap rings have a C-shaped opening structure. They are inserted into the annular grooves of the interface to form axial restraints and prevent the hoses from falling off due to water pressure impact. Specifically, the first hose 7 is snapped into the first inlet 25 of the water distribution valve 2 body by the first snap ring 13; the second hose 8 is snapped into the first outlet 26 of the water distribution valve 2 body by the second snap ring 14.

[0062] like Figure 7 As shown, the lengths of the first hose 7 and the second hose 8 are designed to be able to be pulled out beyond the mounting platform 100 for snap ring assembly, which facilitates the snap ring connection operation by construction personnel in open spaces, avoids working in narrow concealed housing 4, reduces installation difficulty and improves construction efficiency.

[0063] like Figure 6 As shown, cavity 43 accommodates the bending movement of the first hose 7 and the second hose 8. Specifically, the volume of cavity 43 is greater than the space required for the minimum bending radius of the first hose 7 and the second hose 8, ensuring that the first hose 7 and the second hose 8 maintain a safe bending curvature when the depth changes, and preventing waterway blockage.

[0064] Decorative cover plate 9, such as Figure 4 and Figure 9As shown, the decorative cover 9 is fixed to the base 1 and covers the outer side of the mounting surface 100, concealing the base 1 and the long screw 12, thus improving the product's aesthetics. Specifically, the decorative cover 9 has a snap-fit ​​that matches the corresponding slot on the base 1, facilitating installation and removal. The surface of the decorative cover 9 has mounting holes for the adjusting handwheel 10. The cover also has an opening for the water-dividing handle 3 button to extend for user operation.

[0065] The adjustment handwheel 10 is protruding from the decorative cover plate 9 and is connected to the valve core 22 of the temperature control valve 5 through an anti-rotation structure. Users can directly adjust the water temperature on the surface of the decorative cover plate 9 by adjusting the handwheel 10, which is convenient to operate.

[0066] like Figure 12 As shown, the concealed water outlet device meets the installation requirements between the pre-buried depth L1 and the pre-buried depth L2. The appearance of the concealed water outlet device is consistent, and there is no need to adjust the position of the water distribution handle 3.

[0067] In this embodiment, a flexible pipeline connection system is adopted to eliminate the influence of differences in the pre-embedded depth of the concealed housing 4 on the positioning of control components such as the water distribution handle 3 by utilizing the deformation characteristics of the flexible hose. Specifically, the water distribution component is rigidly fixed to the mounting platform 100 via the base 1, keeping the height of the water distribution handle 3 fixed to the mounting platform 100 and unaffected by changes in the pre-embedded depth of the concealed housing 4, thus eliminating the need for secondary adjustment of the water distribution handle 3. Replacing the rigid pipeline with a flexible pipeline eliminates the stringent requirements for positioning accuracy and simplifies the installation process. A cavity 43 is provided inside the concealed housing 4 of the water-passing body. This cavity 43 can accommodate the bending and movement of the flexible hose as its depth changes, ensuring unobstructed water flow at different pre-embedded depths and achieving adaptive compensation for pre-embedded errors.

[0068] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this utility model, but does not constitute a limitation on the scope of protection of this utility model. Modifications, equivalent substitutions, or other improvements to the embodiments of this utility model or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this utility model or the foregoing embodiments, should all be included within the scope of protection of this utility model.
