Description

Technical Field

[0001] This utility model relates to the field of bathroom technology, specifically to a concealed faucet assembly and bathroom device. Background Technology

[0002] Concealed shower systems embed water supply pipes and main control valves within the wall, exposing only the simple control panel and water outlet on the wall surface, thus creating a clean and aesthetically pleasing bathroom space. The core of this system lies in the reliable connection and coordination between the functional modules embedded in the wall and the ultimately exposed panel and water outlet components.

[0003] Currently, existing concealed water supply solutions typically employ a combination of a separate pre-installed box and a panel. The pre-installed box is fixed during the wall decoration stage and contains a water inlet channel and valve core, while the panel is installed later to cover the wall opening and support the water outlet or control handle. To achieve water circuit connectivity, the water outlet interface of the pre-installed box and the water outlet on the panel need to be connected via one or more sections of rigid or flexible connecting pipe, or an adjustable-length independent expansion joint is used as an intermediate connector. The length of the expansion joint is adjusted before panel installation to ensure the correct positioning of the water outlet.

[0004] However, independent connecting pipes or expansion joints increase the complexity of the structure, occupy the limited space inside the embedded box, and may lead to installation difficulties or poor adhesion between the panel and the wall, affecting the final performance and aesthetics. Utility Model Content

[0005] This utility model provides a concealed faucet assembly and bathroom device to solve the problems of difficult panel installation or poor adhesion to the wall.

[0006] In a first aspect, this utility model provides a concealed faucet assembly, comprising: Pre-embedded components, including water supply pipes; The panel assembly is inserted into the pre-embedded assembly along a first direction; A water outlet nozzle is connected to the panel assembly, and the water outlet nozzle is provided with a water inlet channel; The water supply pipe and the water inlet channel both extend along the first direction, and at least a portion of the water supply pipe is slidably inserted into the water inlet channel.

[0007] Beneficial effects: By aligning the water supply pipe of the pre-embedded component and the water inlet channel of the water outlet on the panel component along the insertion direction, and allowing the water supply pipe to slide into the water inlet channel, self-connection of the water circuit between the panel component and the pre-embedded component is achieved during the insertion and assembly process. This structure eliminates the need for independent connecting hoses or complex expansion joints, simplifying the structure, saving space within the pre-embedded box, and allowing for a thinner panel component. Simultaneously, the sliding insertion connection makes the installation process simpler and faster, effectively adapting to different wall thicknesses and installation depth tolerances, improving the installation's error tolerance and reliability.

[0008] In one optional embodiment, the water outlet includes: The housing is connected to the panel assembly. The housing is provided with a flow guiding cavity. The housing is provided with a first protrusion and a second protrusion on two opposite sides along the first direction. The first protrusion is provided with the water inlet channel, which communicates with the flow guiding cavity. The second protrusion is provided with the water outlet channel, which communicates with the flow guiding cavity.

[0009] Beneficial effects: By designing the water outlet nozzle as a structure including a housing, a flow guiding cavity, and protrusions located on both sides, the first protrusion is used to connect the water inlet and the second protrusion is used to discharge the water, so that the water flow is guided and turned in an orderly manner inside the water outlet nozzle.

[0010] In one alternative implementation, the panel assembly includes: The panel body is connected to the housing. The panel body has a side facing the pre-embedded component along the first direction. The side is provided with a groove. The panel body has a side edge that intersects with the side. A notch is provided on the side edge near the pre-embedded component along the first direction. The groove communicates with the notch. A second protrusion is located in the groove and the notch. The second protrusion is adapted to the groove and the notch. The outlet of the water outlet channel is flush with the side.

[0011] Beneficial effects: By placing the second protrusion within the groove and notch of the panel body and making the water outlet flush with the side of the panel, a concealed design of the water outlet structure is achieved. This design makes the water outlet terminal and the panel surface form a smooth and continuous whole, avoiding the visual abruptness caused by the water outlet protruding or concave, and improving the simplicity and aesthetics of the product appearance.

[0012] In one optional embodiment, the flow guiding cavity is provided with filter holes on its cavity wall, and the filter holes are respectively connected to the flow guiding cavity and the water outlet channel.

[0013] Beneficial effects: The filter holes between the guide chamber and the outlet channel are equivalent to setting up a filter barrier before the water outlet. This structure can effectively intercept impurities and particles that may be present in the water path, preventing them from entering and clogging the outlet channel, thereby ensuring smooth and stable water flow, extending the product's service life, and reducing maintenance requirements.

[0014] In one optional embodiment, the water outlet further includes: A first end cap is disposed on the second protrusion near the filter hole. The second protrusion has a first opening that communicates with the water outlet channel. The first end cap is disposed on the first opening and is connected to the second protrusion.

[0015] Beneficial effects: By using a removable first end cap to cover the filter hole area, the cleaning and maintenance of the filter holes are made easier. When the filter holes affect water flow due to the accumulation of impurities, it is not necessary to disassemble the entire outlet or panel; cleaning can be performed simply by opening the first end cap, reducing the difficulty and cost of later maintenance.

[0016] In one alternative embodiment, the first protrusion includes: The second end cap is disposed on the side of the housing away from the second protrusion along the first direction. The housing has a second opening that communicates with the flow guide cavity. The second end cap is disposed on the second opening and is connected to the housing. The water inlet pipe is connected to the second end cap, and the lumen of the water inlet pipe is connected to the flow guide cavity. The lumen of the water inlet pipe is the water inlet channel.

[0017] Beneficial effects: The separate connection between the second end cap and the inlet pipe simplifies the machining process of the outlet nozzle housing and reduces the complexity and cost of mold manufacturing. Simultaneously, this structure facilitates more precise machining and sealing of critical connection points such as the inlet pipe and the second end cap, ensuring the reliability and sealing of the connection between the inlet channel and the guide cavity, thus improving product quality stability.

[0018] In one optional implementation, the embedded component includes: An embedded box is provided with a groove on one side of the panel body along the first direction, and the panel body is covered on the groove; A valve is disposed within the groove and is connected to the water supply pipe.

[0019] Beneficial effects: By integrating valves into the recesses of the embedded box and covering them with the panel body, modular and concealed installation of all core functional components is achieved. This layout makes efficient use of the internal space of the embedded box, resulting in a compact structure and strong overall integrity. During installation, simply connect the panel assembly to the embedded box, simplifying the on-site installation process and improving installation efficiency.

[0020] In one alternative implementation, the panel assembly further includes: A fixing plate is disposed on the side of the panel body facing the embedded box along the first direction. The fixing plate is connected to the panel body. The edge of the fixing plate facing the embedded box in the first direction is provided with a folded edge. A snap-fit ​​block is provided on the folded edge. A snap-fit ​​hole is provided on the groove wall of the groove. The snap-fit ​​block is adapted to the snap-fit ​​hole. The first protrusion penetrates the fixing plate.

[0021] Beneficial effects: By utilizing the snap-fit ​​blocks on the fixing plate and the snap-fit ​​holes on the embedded box, the panel components can be quickly snapped together and fixed. This connection method can usually be completed without tools, making the operation simple and quick, greatly improving installation efficiency, and also providing convenience for later inspection and maintenance.

[0022] In one optional embodiment, a sealing element is provided between the outer wall of the water supply pipe and the inner wall of the water inlet channel.

[0023] Beneficial effects: By installing a seal between the sliding mating surfaces of the water supply pipe and the water inlet channel, good sealing performance is ensured at the water interface even in a dynamic connection state where they can slide relative to each other, effectively preventing leakage.

[0024] Secondly, this utility model also provides a bathroom fixture, including a concealed faucet assembly.

[0025] Beneficial effects: By applying the above-mentioned concealed faucet assembly, the bathroom fixtures (such as shower systems, basin faucets, etc.) that include this assembly have the advantages of simplified structure, convenient installation, small space occupation, simple and beautiful appearance, reliable operation and convenient maintenance.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] The following is combined Figures 1 to 7 The following describes embodiments of the present invention.

[0031] According to an embodiment of the present invention, a concealed faucet assembly is provided, including a pre-embedded component 1, a panel component 2, and a water outlet 3. The pre-embedded component 1 includes a water supply pipe 101. The panel component 2 is inserted into the pre-embedded component 1 along a first direction X. The water outlet 3 is connected to the panel component 2 and is provided with a water inlet channel 301. Both the water supply pipe 101 and the water inlet channel 301 extend along the first direction X, and at least a portion of the water supply pipe 101 is slidably inserted into the water inlet channel 301.

[0032] It should be noted that the embedded component 1 and the panel component 2 are assembled by plugging them together along a first direction X (i.e., the installation direction) perpendicular to the wall. The water supply pipe 101 in the embedded component 1 is a rigid straight pipe, preferably a copper pipe or an engineering plastic pipe. The water outlet 3 on the panel component 2 integrates a water inlet channel 301, which also extends straight along the first direction X.

[0033] During installation, the front end of the water supply pipe 101 is directly inserted into the water inlet channel 301 of the water outlet 3, with a clearance fit between the two, allowing for relative sliding within a certain range. This design allows the installer to fine-tune the fit between the panel and the wall before finally fixing the panel. Even if there is a slight deviation in the pre-embedded depth of the pre-embedded box 102, it can be absorbed and compensated by this sliding stroke, ensuring that the panel always fits tightly against the wall. The entire connection process requires no additional adapter hoses, achieving rapid installation.

[0034] In this embodiment, by arranging the water supply pipe 101 of the pre-embedded component 1 and the water inlet channel 301 of the water outlet 3 on the panel component 2 along the insertion direction, and allowing the water supply pipe 101 to be slidably inserted into the water inlet channel 301, the water circuit self-connection between the panel component 2 and the pre-embedded component 1 is achieved during the insertion assembly process. This structure eliminates the need for independent connecting hoses or complex expansion joint components, simplifies the structure, saves space within the pre-embedded box 102, and allows the panel component 2 to be made thinner. At the same time, the sliding insertion fit makes the installation process simpler and faster, and can effectively adapt to different wall thicknesses and installation depth tolerances, improving the error tolerance and reliability of the installation.

[0035] In one embodiment, the water outlet 3 includes a housing 302 connected to the panel assembly 2. The housing 302 is provided with a flow guiding cavity 3021. The housing 302 is provided with a first protrusion 303 and a second protrusion 304 on two opposite sides along the first direction X. The first protrusion 303 is provided with a water inlet channel 301, which communicates with the flow guiding cavity 3021. The second protrusion 304 is provided with a water outlet channel 3041, which communicates with the flow guiding cavity 3021.

[0036] It should be noted that the first protrusion 303 at the water inlet end is cylindrical, and the axially penetrating channel within it serves as the water inlet channel 301. The second protrusion 304 at the water outlet end can be cylindrical or square depending on design requirements, and its interior is machined with an outlet channel 3041 that communicates with the guide cavity 3021. Water enters through the water inlet channel 301 of the first protrusion 303, undergoes a change in flow direction within the guide cavity 3021, and then flows out through the outlet channel 3041 of the second protrusion 304. This integrated flow channel design ensures smooth water flow and reduces turbulence and noise.

[0037] In this embodiment, by designing the water outlet 3 as a structure including a housing 302, a flow guiding cavity 3021 and protrusions located on both sides, the first protrusion 303 is used to connect the water inlet and the second protrusion 304 is used to discharge water, so that the water flow is guided and turned in an orderly manner inside the water outlet 3.

[0038] In one embodiment, the panel assembly 2 includes a panel body 201 connected to the housing 302. The panel body 201 has a side 2011 facing the pre-embedded component 1 along a first direction X. The side 2011 is provided with a sink 2012. The panel body 201 has a side edge 2013 intersecting with the side 2011. A notch 2014 is provided on the side 2011 at one end near the pre-embedded component 1 along the first direction X. The sink 2012 communicates with the notch 2014. A second protrusion 304 is located in the sink 2012 and the notch 2014. The second protrusion 304 is adapted to the sink 2012 and the notch 2014. The outlet 3042 of the water outlet channel 3041 is flush with the side 2011.

[0039] The panel body 201 may be made of ceramic, tempered glass or high-grade plastic. A recessed groove 2012 matching the shape of the second protrusion 304 is provided on the side 2011 of the panel body 201, and a notch 2014 communicating with the recessed groove 2012 is provided on the bottom side 2013 (or other side 2013) of the panel body 201.

[0040] During assembly, the outer surface of the second protrusion 304 of the water outlet 3 is flush with the back of the panel body 201. The outlet of the water outlet channel 3041 is flush with the periphery of the panel.

[0041] In this embodiment, by placing the second protrusion 304 within the recess 2012 and notch 2014 of the panel body 201, and making the water outlet 3042 flush with the side panel 2011, a concealed design of the water outlet structure is achieved. This design makes the water outlet terminal and the panel surface form a smooth and continuous whole, avoiding the visual abruptness caused by the outward or inward protrusion of the water outlet 3042, and improving the simplicity and aesthetics of the product appearance.

[0042] In one embodiment, a filter hole 3022 is provided on the cavity wall of the flow guiding cavity 3021, and the filter hole 3022 is connected to the flow guiding cavity 3021 and the water outlet channel 3041 respectively.

[0043] To improve water quality and protect downstream components, multiple filter holes 3022 are provided on the cavity wall at the connection between the flow guiding cavity 3021 and the water outlet channel 3041. These filter holes 3022 can be arranged in a ring array or a grid pattern, which can effectively filter out solid particulate impurities in the water (such as pipe rust and sand) without significantly affecting the water flow.

[0044] Optionally, a turbulence protrusion 3024 is provided in the flow guiding cavity 3021 near the filter hole 3022 to turbulent the incoming water, so that the incoming water in the flow guiding cavity 3021 can be buffered and can enter the filter hole 3022 perpendicular to the water inlet direction in the flow guiding cavity 3021 evenly.

[0045] In this embodiment, a filter hole 3022 is provided between the guide cavity 3021 and the water outlet channel 3041, which is equivalent to setting up a filter barrier before the water outlet terminal. This structure can effectively intercept impurities and particles that may exist in the water path, preventing them from entering and clogging the water outlet channel 3041, thereby ensuring smooth and stable water output, extending the service life of the product, and reducing maintenance requirements.

[0046] In one embodiment, the water outlet 3 further includes a first end cap 305 disposed on the side of the second protrusion 304 near the filter hole 3022. The second protrusion 304 is provided with a first opening 3043, which communicates with the water outlet channel 3041. The first end cap 305 is disposed on the first opening 3043 and is connected to the second protrusion 304.

[0047] Optionally, the first end cap 305 can be installed on the first opening 3043 covering the area of ​​the filter holes 3022 by means of threaded connection, snap-fit ​​connection or screw fixation. The first end cap 305 is usually also equipped with a sealing ring. When cleaning is required, simply unscrew or pry open the first end cap 305 to directly expose the filter holes 3022 for rinsing or brushing. After cleaning, tighten the cap again.

[0048] In this embodiment, a removable first end cap 305 is provided to cover the filter hole 3022 area, which facilitates the cleaning and maintenance of the filter hole 3022. When the filter hole 3022 affects the water flow due to the accumulation of impurities, it is not necessary to disassemble the entire water outlet 3 or the panel. Cleaning can be carried out simply by opening the first end cap 305, which reduces the difficulty and cost of subsequent maintenance.

[0049] In one embodiment, the first protrusion 303 includes a second end cap 3031 disposed on the side of the housing 302 away from the second protrusion 304 along a first direction X. The housing 302 has a second opening 3023, which communicates with the flow guiding cavity 3021. The second end cap 3031 covers the second opening 3023 and is connected to the housing 302. The water inlet pipe 3032 is connected to the second end cap 3031, and the lumen of the water inlet pipe 3032 communicates with the flow guiding cavity 3021. The lumen of the water inlet pipe 3032 is a water inlet channel 301.

[0050] Optionally, the second end cap 3031 can be sealed to the second opening 3023 by welding.

[0051] Optionally, the water outlet 3 can be connected to the panel body 201 via a second fastener 6.

[0052] In this embodiment, a separate connection structure is adopted between the second end cap 3031 and the water inlet pipe 3032, which simplifies the processing technology of the water outlet 3 housing 302 and reduces the complexity and cost of mold manufacturing. At the same time, this structure facilitates more precise processing and sealing of key connection parts such as the water inlet pipe 3032 and the second end cap 3031, ensuring the reliability and sealing of the connection between the water inlet channel 301 and the guide cavity 3021, and improving the quality stability of the product.

[0053] In one embodiment, the embedded component 1 includes an embedded box 102 and a valve 103. The embedded box 102 has a groove on one side facing the panel body 201 along the first direction X, and the panel body 201 covers the groove. The valve 103 is disposed in the groove and is connected to the water supply pipe 101.

[0054] The pre-embedded box 102 is an open box with an indented mounting groove on the open side. The mixing valve core, the dividing valve core, and other valve components 103 are fixed in the groove by a bracket. The water supply pipe 101 is connected to the outlet 3042 of the valve component 103.

[0055] Optionally, the embedded box 102 can be connected to the wall via the first fastener 5.

[0056] In this embodiment, by integrating the valve 103 into the recess of the embedded box 102 and covering it with the panel body 201, modular and concealed installation of all core functional components is achieved. This layout makes efficient use of the internal space of the embedded box 102, resulting in a compact structure and strong overall integrity. During installation, it is only necessary to align the panel assembly 2 with the embedded box 102, simplifying the on-site installation process and improving installation efficiency.

[0057] In one embodiment, the panel assembly 2 further includes a fixing plate 202 disposed on the side of the panel body 201 facing the embedded box 102 along the first direction X. The fixing plate 202 is connected to the panel body 201. The side edge 2013 of the fixing plate 202 facing the embedded box 102 in the first direction X is provided with a folded edge 203. A snap-fit ​​block 204 is provided on the folded edge 203. A snap-fit ​​hole 104 is provided on the groove wall of the groove. The snap-fit ​​block 204 is adapted to the snap-fit ​​hole 104. The first protrusion 303 penetrates the fixing plate 202.

[0058] The edge of the fixing plate 202 is bent towards the embedded box 102 to form a folded edge 203, and an outwardly protruding snap-fit ​​block 204 (which can be an elastic snap tongue or a rigid protrusion) is stamped on the folded edge 203. Correspondingly, snap-fit ​​holes 104 corresponding to the position and shape of snap-fit ​​blocks 204 are provided around the periphery of the recessed opening of the embedded box 102. During installation, the panel assembly 2 is aligned with the embedded box 102, and pressure is applied, so that the snap-fit ​​block 204 can be snapped into the snap-fit ​​hole 104 to achieve quick locking. At the same time, a through hole is opened in the center of the fixing plate 202 to allow components such as the water outlet 3 to pass through.

[0059] In this embodiment, the snap-fit ​​block 204 on the fixing plate 202 cooperates with the snap-fit ​​hole 104 on the embedded box 102 to achieve quick snap-fit ​​fixing of the panel assembly 2. This connection method can usually be completed without the use of tools, which is simple and quick to operate, can greatly improve the installation efficiency, and also provides convenience for later inspection and maintenance.

[0060] In one embodiment, a sealing element 4 is provided between the outer wall of the water supply pipe 101 and the inner wall of the water inlet channel 301.

[0061] Optionally, an annular groove may be provided on the outer wall of the water supply pipe 101 and / or the inner wall of the water inlet channel 301, and a sealing ring may be installed in the groove.

[0062] Alternatively, multiple sealing rings can be used.

[0063] In this embodiment, a sealing element 4 is provided between the sliding mating surfaces of the water supply pipe 101 and the water inlet channel 301 to ensure that the water interface can maintain good sealing performance even in a relatively sliding dynamic connection state, effectively preventing leakage.
