Description

Technical Field

[0001] This invention relates to the field of bathroom product technology, and specifically to a concealed shower system that is easy to install. Background Technology

[0002] Most shower systems currently on the market are exposed shower system sets. These sets are mounted on the outside of the wall, taking up space and being prone to bumps and knocks, which is inconvenient. As consumer demands have increased, many manufacturers have also developed shower system sets for concealed installation. However, these require specific piping layouts, and changing the layout incurs additional piping costs, significantly limiting consumer demand for upgrades. Furthermore, the valve bodies or connecting structures of these concealed shower system sets are often made of copper, which can leach metal elements upon contact with water, potentially affecting water quality and hygiene. Summary of the Invention

[0003] To address the problems existing in the prior art, this invention provides a concealed shower system that is easy to install. This system is easy to install, allows for easy switching of pipe pre-embedding and layout methods, and the control valve body of the system is made of all-plastic structure, which greatly improves the hygiene of the water quality.

[0004] The technical solution adopted to achieve the above-mentioned objectives of this invention is as follows:

[0005] A concealed shower system that is easy to install also includes a mixing valve and a switching valve. The mixing valve includes a mixing valve body and a first fixing sleeve for installing the mixing valve core. The mixing valve body is provided with a cold water interface, a hot water interface and a mixed water outlet. The cold water interface and the hot water interface are located on the same side of the axis of the mixed water outlet. The first fixing sleeve and the mixing valve body are rotated and locked together. The switching valve includes a switching valve body and a second fixing sleeve for installing the switching valve core. The switching valve body is provided with a mixed water inlet, a first outlet and a second outlet. The second fixing sleeve and the switching valve body are rotated and locked together. The mixed water outlet is connected to the mixed water inlet.

[0006] The mixing valve body is provided with a first mounting groove that mates with the first fixed sleeve. The inner wall of the first mounting groove is provided with a first screw-fit groove. The outer wall of the first fixed sleeve is provided with a first screw-fit key that rotatably mates with the screw-fit groove. The first fixed sleeve and the mixing valve body are rotatably connected by the first screw-fit key and the first screw-fit groove.

[0007] The switching valve body is provided with a second mounting groove that mates with the second fixed sleeve. The inner wall of the second mounting groove is provided with a second screw-fit groove. The outer wall of the second fixed sleeve is provided with a second screw-fit key that rotatably mates with the screw-fit groove. The second fixed sleeve and the switching valve body are rotatably connected by the second screw-fit key and the second screw-fit groove.

[0008] The first spin-fitting groove is L-shaped and includes a first embedding section and a first locking section that are interconnected. The first embedding section extends to the opening of the second mounting groove. The second spin-fitting groove is L-shaped and includes a second embedding section and a second locking section that are interconnected. The second embedding section extends to the opening of the second mounting groove.

[0009] There are two or more first screw-fit grooves, which are evenly distributed along the circumference of the first mounting groove. There are two or more first screw-fit keys, which are evenly distributed along the circumference of the first fixing sleeve. There are two or more second screw-fit grooves, which are evenly distributed along the circumference of the second mounting groove. There are two or more second screw-fit keys, which are evenly distributed along the circumference of the second fixing sleeve.

[0010] The mixing valve body is provided with a plug interface, which is connected to the mixed water outlet, and the plug interface and the mixed water outlet are distributed on the same straight line.

[0011] The plug interface, mixing water outlet, cold water interface, hot water interface and mixing valve body constitute a π-shaped mechanism, wherein the cold water interface and hot water interface are distributed on both sides of the mixing valve body, and the cold water interface and hot water interface are symmetrical about the axial section of the mixing valve body.

[0012] The mixing valve body is also provided with a third outlet. The mixing water inlet, the first outlet, the second outlet and the third outlet are arranged in a cross shape, and the mixing water inlet and the second outlet are distributed on the same straight line.

[0013] The mixed water outlet and the mixed water inlet are connected by a heat-fusion socket connection.

[0014] Compared with the prior art, the beneficial effects and advantages of the present invention are as follows:

[0015] 1. The system's mixing valve body features a cleverly designed and reasonable layout for the cold water and hot water interfaces. When the pipeline is pre-buried in the ground, simply rotate the mixing valve body to make the cold water and hot water interfaces face downwards. When the pipeline needs to be pre-buried in the ceiling, simply rotate the mixing valve body 180 degrees to make the cold water and hot water interfaces face upwards. This avoids the problem of pipeline crossings and increased difficulty in pre-buried pipelines when changing the pipeline pre-buried and laying methods of existing mixing valves.

[0016] 2. The fixing sleeve of the mixing valve core of the system is connected to the mixing valve body by a rotating fastening method, and the fixing sleeve of the switching valve core is connected to the switching valve body by a rotating fastening method. This allows the mixing valve body and the switching valve body to be made entirely of plastic, avoiding the problems of rust and metal element precipitation that can occur with metal inserts, thus ensuring the hygiene of the water quality and improving the service life of the control valve.

[0017] 3. The control valve body of this system is made entirely of plastic, resulting in low production costs, light product weight, and long service life.

[0018] 4. The fixing sleeve of the control valve core of the system is connected to the control valve body by a rotating fastening method, which makes it easy to remove the control valve core from the control valve body and facilitate the maintenance of the control valve.

The first screw-fit groove 10 is L-shaped and includes a first embedding section 1001 and a first locking section 1002 that are interconnected. The first embedding section 1001 extends to the opening of the first mounting groove 9. There are three first screw-fit grooves 10, and the three first screw-fit grooves 10 are evenly distributed along the circumference of the first mounting groove 9. Figure 5 As shown, the inner side of the outer wall of the first fixed sleeve 7 is provided with a first screw key 11 that rotates with the first screw groove 10. There are three first screw keys 11, and the three first screw keys 11 are evenly distributed along the circumference of the first fixed sleeve 7.

[0034] The first fixed sleeve 7 and the mixing valve body 1 are connected by a first key 11 and a first groove 10 through a rotatable fastening mechanism to achieve mutual locking. When the first fixed sleeve 7 is nested into the first mounting groove 9, the first key 11 on the first fixed sleeve 7 is first inserted into the first groove 10 through the first insert section 1001. After insertion, the first fixed sleeve 7 is rotated so that the first key 11 enters the first locking section 1002 for fastening and locking. There are many ways for the first groove 10 and the first key 11 to cooperate. The first key 11 is not limited to the arc-shaped block shape of this embodiment, and the first groove 10 is not limited to the L-shape of this embodiment. It can also be other shapes that can be fastened and locked.

[0035] The mixing valve core 8 is installed on the mixing valve body 1 through the first fixing sleeve 7. The first handle 27 or the first knob is connected to the mixing valve core 8, and the mixing valve core 8 is controlled to move through the first handle 27 or the first knob.

[0036] The switching valve includes a switching valve body 12, a second fixing sleeve 18 for mounting the switching valve core, the switching valve core, and a second handle. Both the switching valve body 12 and the second fixing sleeve 18 are made of plastic.

[0037] The switching valve body 12 is equipped with a mixing water inlet 13, a first outlet 14, a second outlet 15, and a third outlet 16. These are arranged in a cross shape. The mixing water inlet 13 and the second outlet 15 are located on the same straight line, as are the first outlet 14 and the third outlet 16. The first outlet 14 can be connected to a PPR pipe socket, which extends to the overhead shower head installation position and connects to the overhead shower head 24. The second outlet 15 can be connected to a PPR pipe socket, which extends to the handheld shower head installation position and connects to the handheld shower head 25. The third outlet 16 can be connected to a PPR pipe socket, connecting to a lower water tap 26, which can be used for washing mops, etc.

[0038] The switching valve body 12 is provided with a second mounting groove 17 that mates with the second fixed sleeve. The inner wall of the second mounting groove 17 is provided with a second screw-fit groove. The second screw-fit groove is L-shaped and includes a second embedded section and a second locking section that are interconnected. The second embedded section extends to the opening of the second mounting groove. There are three second screw-fit grooves, evenly distributed along the circumference of the second mounting groove 17. The inner side of the outer wall of the second fixed sleeve 18 is provided with three second screw-fit keys that rotatably engage with the second screw-fit grooves. These three keys are evenly distributed along the circumference of the second fixed sleeve 18.

[0039] The second fixed sleeve 18 and the switching valve body 15 are connected by a second key and a second slot to achieve mutual locking. When the second fixed sleeve 18 is nested into the second mounting groove 17, the second key on the second fixed sleeve 18 is first inserted into the second slot through the second embedding section. After insertion, the second fixed sleeve is rotated to engage the second key in the second locking section. The second slot and key can be fitted in various ways. The second key is not limited to the arc-shaped block shape of this embodiment, and the second slot is not limited to the L-shape of this embodiment; it can also be other shapes that can engage and lock.

[0040] The valve core of the switching valve is installed on the valve body 12 of the switching valve through the second fixing sleeve 18. The second handle or the second knob is connected to the valve core of the switching valve, and the valve core of the switching valve is controlled to move through the second handle or the second knob.

[0041] The embedded box includes an upper box body 20 and a lower box body 21.

Then, rotate the switching valve body 12 so that the first outlet 14 faces upwards and the third outlet 16 faces downwards. Finally, connect the mixing water outlet 4 and the mixing water inlet 13 with a heat fusion socket connection. The assembly method of the mixing valve body 1 and the switching valve body 12 is as follows. Figure 6 As shown, assemble the first fixing sleeve 7, mixing valve core 8, first handle 27 or first knob, second fixing sleeve 18, switching valve core, and second handle or second knob to form a concealed valve. Place the concealed valve on the lower housing 21, and fasten the upper housing 20 together with screws to form a pre-embedded component. Embed the pre-embedded component into the wall. After the pipeline is pre-embedded, connect the cold water pipe 23, hot water pipe 22, handheld shower head 25, and overhead shower head 24 to assemble as shown. Figure 2 The concealed shower system shown.

[0043] If the pipeline needs to be pre-buried in the ground, rotate the mixing valve body 1 so that the hot water interface 3 and the cold water interface 2 face downwards. Then rotate the switching valve body 12 so that the first outlet 14 faces upwards and the third outlet 16 faces downwards. Then connect the mixing water outlet 4 and the mixing water inlet 13 with a heat fusion socket connection. At this time, the assembly method of the mixing valve body 1 and the switching valve body 12 is as follows.
