Detailed Implementation

[0042] The following is combined with Figures 1-13 This utility model will be described in detail.

[0043] This embodiment provides a pre-embedded device, including a box 10. The box 10 includes a metal part 102 and a plastic part 101 wrapped around the outside of the metal part 102. The internal cavities of the metal part 102 and the plastic part 101 are interconnected to form an installation cavity 20. The metal part 102 has several installation holes 30 communicating with the installation cavity 20. The installation cavity 20 is used to place a valve body assembly, and each installation hole 30 is used for connecting the pipe interface of the valve body assembly to an external pipe. A portion of the plastic part 101 protrudes from the pre-embedded groove and forms a sealing section 50. The length of the sealing section 50 can be cut to fit the current pre-embedded depth. Compared with a box 10 that uses only plastic parts 101, the combination of the metal part 102 and the plastic part 101 enhances the sealing effect and has better strength. At the same time, in conjunction with the sealing section 50, it isolates the inside of the box 10 from the outside, preventing water from flowing into the wall from the box 10 when the valve body assembly inside the box 10 leaks, reducing the possibility of problems such as mold growth and tile detachment.

[0044] In this embodiment, the metal part 102 and the plastic part 101 are integrally molded to form the box body 10. During the overmolding process, the metal part 102 is first placed in the mold cavity, and then molten plastic flows into the mold cavity and completely covers the outer surface of the metal part 102. After molding and cooling, as shown... Figure 7 As shown, the metal part 102 and the plastic part 101 are tightly joined, which can isolate the wall from water when the valve body assembly leaks, preventing water from flowing out of the box 10. Furthermore, the encapsulated box 10 has high strength and can withstand certain external impacts during installation. In other embodiments, the metal part 102 and the plastic part 101 are separately molded and then assembled into the box 10. In the separate molding process, the metal part 102 and the plastic part 101 are manufactured separately, and then connected together to form the box 10. A sealing ring is also fitted between the metal part 102 and the plastic part 101 to prevent leakage.

[0045] like Figure 6 As shown, the plastic part 101 includes a base 1011 and an extension 1012 connected sequentially along the axial direction. The metal part 102 is connected to the base 1011, and the end of the extension 1012 away from the base 1011 forms a sealing section 50. The outer wall of the metal part 102 is provided with a plurality of connecting protrusions 1021 extending radially outward along the metal part 102. The connecting protrusions 1021 are provided with connecting holes communicating with the inner wall of the metal part 102. Each connecting hole forms a mounting hole 30, and at least some of the mounting holes 30 are provided with internal threads to improve the convenience of connecting the valve body to the external pipeline. The plastic part 101 is provided with a connector sleeve 1013 wrapped around the outside of the protrusion.

[0046] like Figure 5As shown, the pre-embedded device also includes a fixing frame detachably connected to the outside of the box 10. The fixing frame is used to fix the box 10 to the false wall 120. When the box 10 needs to be pre-embedded in the concrete solid wall 130, the fixing frame can be removed, and the box 10 can be directly fixed to the concrete solid wall 130. When the box 10 needs to be connected to the false wall 120 such as wall panels or decorative panels, the fixing frame is installed, and the box 10 is installed to the false wall 120 through the fixing frame, thereby expanding the applicable range of the box 10. Furthermore, the fixing frame includes a first fixing member 701 and a second fixing member 702 that are separately connected. The first fixing member 701 and the second fixing member 702 are provided with a first connecting position 801, and the outer side wall of the box 10 is provided with a second connecting position 802 that is concave and convex with the first connecting position 801. Specifically, the first fixing member 701 and the second fixing member 702 are provided with positioning protrusions, which constitute the first connecting position 801. The outer surface of the extension 1012 is provided with a positioning groove, which constitutes the second connecting position 802. The positioning protrusions and the positioning groove are connected together. During installation, the first fixing member 701 and the second fixing member 702 are located on both sides of the extension 1012. The first fixing member 701 and the second fixing member 702 gradually approach each other and connect together. At the same time, the positioning protrusions connect to the positioning grooves, completing the installation of the fixing frame. In other embodiments, the fixing frame is integrally formed and is connected to the extension 1012 by threads or other snap-fit ​​methods.

[0047] The sealing section 50 can be adapted to different application scenarios of the embedded device. When embedded in the false wall 120, such as... Figure 1 As shown, the false wall 120 is composed of wooden columns, beams, and boards. Its exterior wall materials are mostly embedded within a wooden frame to form a composite structure. The interior of the wall is filled with insulation material and covered with a waterproof layer and a decorative finish. Because its structure itself already possesses waterproof, insulation, and moisture-proof functions, it is usually unnecessary to install a sealing element 60 outside the sealing section 50. However, when pre-embedded in the solid wall 130, such as... Figure 2 As shown, there is a gap between the wall of the solid wall 130 and the box 10. External water can be prevented from seeping in by adding a sealant 60 between the sealing section 50 and the wall.

[0048] When pre-embedding a solid wall of 130, such as Figure 2 As shown, the sealing element 60 is laid flat and sealed to the wall, and at least the end of the sealing element 60 is sealed against the outer facade of the box 10. Alternatively, the sealing element 60 is sealed and fitted onto the outer facade of the box 10, and at least the end of the sealing element 60 is against the wall, so as to seal the gap between the box 10 and the wall and reduce the possibility of water flowing in from the gap between the box 10 and the wall.

[0049] The sealing element 60 includes an integrally formed sealing straight section 601 and a sealing horizontal section 602. The space enclosed by the sealing straight section 601 is used for the housing 10 to pass through. The sealing straight section 601 is sealed to the outer facade of the housing 10, and the sealing horizontal section 602 is sealed to the wall. The cross-section of the sealing element 60 can be L-shaped or C-shaped, etc.

[0050] like Figures 2 to 4 As shown, the height of the box body 10 is greater than the height of the pre-embedded groove in the wall, and the position of the box body 10 protruding from the pre-embedded groove constitutes the sealing section 50. The first end of the sealing element 60 is connected to the sealing section 50. The sealing section 50 has a smooth surface, making the connection between the sealing section 50 and the sealing element 60 flat and improving the sealing connection between the two. Here, "smooth surface" should be understood as having no protrusions or recesses on the surface of the sealing section 50. In addition, the sealing section 50 is generally made of injection molding, and the surface roughness of the unpolished injection molding is generally 0.02-1.25 micrometers, which is sufficient to meet the sealing connection requirements.

[0051] The sealing element 60 is sheet-shaped. During installation, after making an opening in the sealing element 60 to fit the box body 10, the sealing element 60 is directly fitted onto the outside of the box body 10. The first end of the sealing element 60 is connected to the sealing section 50, and the second end of the sealing element 60 is laid flat and connected to the wall. Specifically, the sealing element 60 is made of polypropylene cloth, a synthetic fiber material made from polypropylene. Its main functions include waterproofing, seepage prevention, reinforcement and isolation, and environmental protection, and it is widely used in construction engineering, water conservancy engineering, home decoration, and other fields. In other embodiments, the sealing element 60 can be a multi-layer structure composed of a non-woven fabric layer and a rubber layer, or it can be made of other elastic waterproof materials.

[0052] The box body 10 is also provided with several fixing positions 40 for fasteners to be inserted to fix the box body 10 to the wall. At least one of the metal part 102 and the plastic part 101 is provided with a fixing position 40, and there is an adjustment gap between the fastener and the fixing position 40, so that the box body 10 can rotate relative to the wall, thereby eliminating the tilt angle of the box body 10. The tilt angle of the box body 10 can be eliminated without reinstalling the box body 10, simplifying the installation process.

[0053] like Figure 9 , Figure 11 and Figure 12 As shown, each fixed position 40 is an arc-shaped hole, and the center positions of the corresponding arc-shaped holes overlap with each other. Specifically, each arc-shaped hole is located on the same circumference, or on concentric circumferences with different radial dimensions, ensuring that the box 10 can rotate relative to the wall.

[0054] The shower device also includes a mounting panel 90 that is detachably connected to the housing 10. The mounting panel 90 prevents dust and other debris from entering the housing 10 and strengthens the structure of the housing 10 to prevent deformation during installation. At the same time, the mounting panel 90 or the housing 10 is equipped with a level 100 to facilitate observation of whether the housing 10 is currently in a level state.

[0055] The installation process of the pre-embedded device proposed in this embodiment is as follows:

[0056] Install the box 10 into the pre-embedded groove in the wall, and insert fasteners through the fixing holes to complete the initial fixing of the box 10. If the box 10 is tilted at this time, such as Figure 8 and Figure 9 As shown, with an angle of inclination α, the bubble level in the level ruler 100 is tilted to one side. By rotating the box 10, the bubble level is brought to the center of the level ruler 100. At this point, the tilt angle is eliminated, and the box 10 is in a horizontal position, as shown. Figure 10 and Figure 11 Then connect the first end of the seal 60 to the sealing end, and connect the second end of the seal 60 to the wall. Finally, install the mounting panel 90 into the mounting cavity 20 to complete the installation.

[0057] When installing the valve body assembly into the housing 10, remove the mounting panel 90, install the valve body assembly into the mounting cavity 20, and then connect the decorative panel 110 to the housing 10, as follows. Figure 13 As shown.

[0058] This embodiment also proposes a shower system, including a pre-embedded device as described above, and at least a handheld shower head and an overhead shower head, wherein the handheld shower head and the overhead shower head are connected to the water pipe interface of the valve body assembly.

[0059] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
