Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of bathroom products, and particularly relates to a modular pre-buried water outlet valve assembly and a shower water outlet system. BACKGROUND

[0002] Different consumers have different consumer demands for bathroom shower systems based on different use scenarios, decoration styles, and functional requirements, and even during the decoration process, the consumer demand may suddenly change, and the function and style of the shower system need to be changed. For example, temporarily changing the decoration style, changing the exposed shower system into a concealed shower system, which can only re-lay the pre-buried water pipe and pre-buried components, and if the wall has been completed, the consumer can only face two choices: either spend a large cost to knock down the decorated wall to re-lay, or give up the change and accept the shower system that is not coordinated with the decoration style. For changing the concealed shower system into the exposed shower system, the prior art also has similar problems. Once the pre-buried box group and water pipe are laid, it is necessary to change the exposed shower system, and the wall and pre-buried box group need to be reprocessed, which wastes a large amount of economic cost and construction period cost, and greatly limits the freedom of consumer demand selection.

[0013] Preferably, the shower water outlet system further comprises a water outlet faucet, and the water outlet faucet is mounted on the bypass water pipe.

[0014] As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) Using the modular pre-embedded water outlet valve assembly of the present invention, during the pre-embedded stage of the shower system, only the pre-embedded box group needs to be pre-embedded in the wall and the inlet and outlet pipes need to be connected. Even after the bathroom wall decoration is completed, the user can still freely choose to continue using the concealed shower system or change to the exposed shower system by selecting different types of water outlet valve groups, without damaging the wall or rearranging the water pipes.

[0016] (2) The pre-embedded box assembly is equipped with a bypass clearance groove. When a concealed water outlet device is used, the valve body of the water valve assembly is directly attached to the pre-embedded core of the pre-embedded box assembly. The bypass clearance groove can reserve a receiving position for the valve body to add a bypass water outlet pipe. It can be adapted to different types of valve bodies. Users only need to replace the valve body to change the number of water outlets of the water outlet device according to their needs, without having to replace the pre-embedded box assembly.

[0017] (3) The valve body is equipped with a bypass water path that connects to the water outlet, and the bypass water outlet is connected to the bypass water outlet through the bypass water outlet pipe. Water can be discharged directly from the water outlet. The added water path does not need to go through the pre-embedded core. The water outlet can be added without changing the pre-embedded box assembly, providing users with more diverse needs.

[0018] (4) The mixing valve assembly uses a mixing valve core and a mixing valve seat is installed on the valve body. The mixing valve core is used for adjustment.

[0019] The opening size of the first and second water inlets controls the ratio of water entering the mixing chamber of the mixing valve core from the cold water and hot water circuits and the hot water inlet circuit. This controls the mixing ratio of cold water and hot water, thereby adjusting the temperature of the mixed water and outputting the mixed water to the outlet circuit, making it easy to control the outlet water temperature of the water outlet device.

[0020] (5) A mixing valve seat is provided on the valve body, which makes it easy to achieve different mixing valve groups by replacing the mixing valve core.

[0021] Functions include the ability to use either a manually adjustable mixing valve core or a thermostatic mixing valve core, allowing users to easily select and replace them in a modular fashion according to their needs.

[0022] (6) By setting the switch valve core, the opening and closing control of the outlet and the bypass outlet can be realized independently, thereby independently controlling the independent water output control of each water output path of the water output device, and also realizing the simultaneous water output of multiple paths.

[0023] (7) The valve core seat adopts an open cavity structure, and the open cavity is coaxially aligned with the water outlet and the bypass water outlet.

[0024] The design facilitates the installation of the switch valve core, enabling easy control of the opening and closing of the outlet and bypass outlet.

[0025] (8) The bypass outlet pipe is rotatably connected to the bypass outlet. By rotating it, the direction of the water outlet can be changed, making it convenient for users to adjust the water flow direction.

[0026] (9) The water valve assembly also includes a connector, through which the secondary water inlet channel of the connector is connected to the water inlet of the embedded core.

[0027] The water outlet is connected to the outlet of the pre-embedded core through the secondary outlet of the connector. The extension of the connector allows the valve body to be adapted to the pre-embedded box assembly outside the box cavity. This makes the valve body of the water valve assembly installed beyond the wall, turning the valve body into an exposed valve body. This achieves the goal of changing the water outlet device from concealed to exposed without changing the installation of the pre-embedded box assembly. Attached Figure Description

[0059] Example 1.

[0060] See Figures 1 to 3 The embodiment provides a modular pre-buried water outlet valve assembly, which comprises a pre-buried box group 1, a water passing valve group 2, a water mixing valve group 3, a switch valve group 4 and a cover plate 5. Wherein:

[0061] As Figures 4 to 6 shown, the pre-buried box group 1 comprises a box body 11 and a pre-buried core 12. The box body 11 comprises a bottom plate 111 and a wall plate 112, the wall plate 112 is fixedly connected to the bottom plate 111 and forms a box cavity 13 with the bottom plate 111; the pre-buried core 12 is arranged in the box cavity 13 and fixedly installed with the box body 11.

[0062] In the embodiment, the pre-buried core 12 comprises a waterway part 14 and a shell 15. The waterway part 14 is made of metal material, and the shell 15 is used for encapsulating the waterway part 14 and is integrally injection molded by hot melt plastic. The pre-buried core 12 is provided with a first water passing valve seat 125 on the shell 15 away from the bottom plate 111, and the first water passing valve seat 125 forms a plane structure to match the water passing valve group 2. The waterway part 14 comprises a water inlet channel and a water outlet channel, specifically, the water inlet channel comprises a cold water channel 121 for connecting an external cold water pipe and a hot water channel 122 for connecting an external hot water pipe; the water outlet channel comprises a first water outlet channel 123 for connecting an external water outlet pipe and a second water outlet channel 124, so as to realize connection of two water outlet channels from the pre-buried box group 1.

[0063] The first water passing valve seat 125 is provided with a cold water inlet 1251 for communicating the cold water channel 121, a hot water inlet 1252 for communicating the hot water channel 122, a first water outlet 1253 for communicating the first water outlet channel 123, and a second water outlet 1254 for communicating the second water outlet channel 124.

[0064] The box cavity 13 comprises a bypass accommodation slot 131, which is located at the side of the pre-buried core 12 and is formed by the wall plate 112, the bottom plate 111 and the side wall of the pre-buried core 12, and is used for accommodating the bypass water outlet pipe 2132 added by the water passing valve group 2.

[0065] The wall plate 112 of the box body 11 is provided with a pipe hole 1121 corresponding to the cold water channel 121, the hot water channel 122, the first water outlet channel 123 and the second water outlet channel 124. The cold water channel 121, the hot water channel 122, the first water outlet channel 123 and the second water outlet channel 124 of the pre-embedded core 12 in the embodiment are all extended to the outside of the box body 11 through the corresponding pipe holes 1121.

[0066] In the embodiment, the cold water channel 121, the hot water channel 122, the first water outlet channel 123 and the second water outlet channel 124 each include a hot-melt outer pipe 126 and a positioning inner pipe 127. The hot-melt outer pipe 126 is arranged on the shell 15, which is convenient for integrated molding when the shell 15 is manufactured. The positioning inner pipe 127 is arranged on the water channel piece 14, and after the shell 15 encapsulates the water channel piece 14, the positioning inner pipe 127 is arranged on the inner side of the hot-melt outer pipe 126, so that a connecting ring groove 128 is formed between the positioning inner pipe 127 and the hot-melt outer pipe 126. The water inlet pipe and the water outlet pipe are connected to the cold water channel 121, the hot water channel 122, the first water outlet channel 123 and the second water outlet channel 124 through the connecting ring groove 128, and are connected to the pre-embedded core 12 through hot-melt connection with the hot-melt outer pipe 126, so as to realize the sealed connection between the water inlet pipe and the water outlet pipe and the pre-embedded core 12. In the embodiment, the positioning inner pipe 127 is used to position the externally connected hot-melt water pipe, so as to limit the hot-melt part of the water pipe and the hot-melt outer pipe 126 at a specific position. Therefore, during the plug-in installation of the water inlet channel and the water outlet channel and the external water pipe, the abutting position of the hot-melt parts does not need to be determined again, so as to realize the quick positioning of the hot-melt part, reduce the operation difficulty and ensure the yield of the hot-melt finished product.

[0067] As shown in FIG. 1, Figures 7 to 9 The water passing valve group 2 in the embodiment is composed of a valve body 21. The valve body 21 is accommodated in the box cavity 13 of the pre-embedded box group 1 and is adaptively connected to the pre-embedded core 12. The valve body 21 is provided with a water inlet channel 211, a water outlet channel 212 and a bypass water channel 213. On the front side of the valve body 21, a water mixing valve seat 214 for connecting the water mixing valve group 3 is arranged. On the rear side of the valve body 21, a second water passing valve seat 215 for connecting the pre-embedded box group 1 is arranged.

[0068] The water inlet path 211 includes a cold water inlet path and a hot water inlet path, and the cold water inlet path and the hot water inlet path form water inlets 2151 on the second water passing valve seat 215, and are respectively matched with the cold water inlet 1251 and the hot water inlet 1252 of the first water passing valve seat 125 through the water inlets 2151. The water mixing valve seat 214 is provided with a first water inlet 2141, a second water inlet 2142 and a water mixing outlet 2143; the first water inlet 2141 and the second water inlet 2142 are respectively connected with the cold water inlet path and the hot water inlet path, and the water mixing outlet 2143 is connected with the water outlet path 212 of the valve body 21, so as to output the cold water and the hot water passing through the pre-buried box group 1 to the water outlet path 212 after mixing by the water mixing valve group 3.

[0069] In the embodiment, the valve body 21 is further provided with a bypass water path 213 connected with the water outlet path 212, and two bypass water outlets 2131 and two bypass water pipes 2132 are arranged on the bypass water path 213. One of the bypass water pipes 2132 extends from the bypass water outlet 2131 arranged on the second water passing valve seat 215 into the bypass accommodation groove 131 of the pre-buried box group 1 and then discharges water on the wall plate 112 below the pre-buried box group 1; the other bypass water pipe 2132 extends forward from the bypass water outlet 2131 on the front side of the valve body 21 and can be used for connecting an external water faucet or other water path control device.

[0070] On the second water outlet valve seat, the water outlet path 212 is provided with two water outlets 2152 to connect the water outlet path 212 with the first water outlet 123 and the second water outlet 124 of the pre-buried box group 1. The valve body 21 is further provided with three valve core seats 216 corresponding to the two water outlets 2152 and the bypass water outlet 2131 arranged on the second water passing valve seat 215, for assembling the on-off valve core 41 to facilitate the opening and closing control of the water outlets 2152 and the bypass water outlet 2131. In the embodiment, the valve core seat 216 is arranged in an open cavity structure, and each open cavity is coaxially arranged corresponding to the water outlet 2152 and the bypass water outlet 2131, which is simple in structure and convenient for installing and matching various on-off valve cores 41, so that the on-off valve core 41 can control the opening and closing of the corresponding water outlet 2152 and bypass water outlet 2131, thereby controlling the connection state of the water outlet path 212 and the bypass water path 213 and the water outlet pipe, and further controlling the water outlet.

[0071] On the second water outlet valve seat of the valve body 21, a sealing groove 2153 and a sealing ring 2154 are arranged, the sealing groove 2153 is arranged along the outer periphery of the water inlet 2151 and the water outlet 2152, and the sealing ring 2154 is embedded in the sealing groove 2153. When the valve body 21 is assembled with the pre-buried box group 1, the second water passing valve seat 215 and the first water passing valve seat 125 are matched and connected, and the sealing ring 2154 forms a sealing effect between the water inlet path 211 and the water inlet, and between the water outlet path 212 and the water outlet.

[0072] As Figure 10 shown, in this embodiment, the water mixing valve group 3 adopts a manually adjustable water mixing valve core 31, which is installed on the water mixing valve seat 214. The water mixing valve core 31 controls the water quantity ratio of the cold water and hot water paths entering the water mixing cavity of the water mixing valve core 31 by adjusting the opening size of the first water inlet 2141 and the second water inlet 2142, adjusts the mixing ratio of the cold water and the hot water, thereby adjusting the temperature of the mixed water, and outputs the mixed water to the water outlet path 212. The on-off valve group 4 adopts a general press-type on-off valve core 41, each of which is respectively inserted and installed on the valve core seat 216 of the opening cavity structure, and controls the opening and closing of the water outlet 2152 and the bypass water outlet 2131 through press operation.

[0073] The pre-embedded box group 1 is installed in the wall body, after the valve body 21, the water mixing valve core 31, and the on-off valve core 41 are adaptively installed, the cover plate 5 is attached with the box body 11 of the pre-embedded box group 1, so that the pre-embedded water outlet valve assembly can be hidden in the wall body, so that the water outlet valve assembly is flush with the wall body, and the overall integrity and aesthetic degree of the concealed shower system are realized.

[0074] The modular pre-embedded water outlet valve assembly of this embodiment, as a device for controlling the water outlet and adjusting the water outlet temperature of the water path of the shower system, when installed and used, first embeds the pre-embedded box group 1 in the wall body, and the external water inlet pipe is connected with the cold water path 121 and the hot water path 122 outside the box body 11, the water outlet pipes of the top shower and the handheld shower are connected with the first water outlet path 123 and the second water outlet path 124 outside the box body 11; the valve body 21 is installed in the box cavity 13 by fixed connection between the second water passing valve seat 215 of the valve body 21 and the first water passing valve seat 125 of the pre-embedded core 12, and the pre-embedded box group 1 is completed. At this time, the water inlets 2151 of the second water passing valve seat 215 are respectively adapted to the cold water inlet 1251 and the hot water inlet 1252 of the first water passing valve seat 125, the cold water inlet path of the valve body 21 is in communication with the cold water path 121, and the hot water inlet path is in communication with the hot water path 122; the water outlets 2152 on the second water passing valve seat 215 are respectively adapted to the first water outlet 1253 and the second water outlet 1254 of the first valve seat, and the water outlet path 212 of the valve body 21 is respectively communicated with the first water outlet path 123 and the second water outlet path 124. After the valve body 21 is attached with the pre-embedded box group 1, the bypass water outlet pipe 2132 provided at the rear side of the valve body 21 is accommodated in the bypass accommodation slot 131 of the pre-embedded box group 1.

[0075] In use, cold water and hot water enter the embedded core 12 of the embedded box assembly 1 through the external inlet pipes connecting the cold water channel 121 and the hot water channel 122, respectively. They then enter the cold water inlet and hot water inlet of the valve body 21 and are guided to the mixing chamber of the mixing valve core 31. By manually controlling the knob of the mixing valve core 31, the opening size of the first inlet 2141 and the second inlet 2142 is changed, adjusting the ratio of cold water and hot water entering the mixing chamber. The cold water and hot water flow within the mixing chamber... After being mixed into mixed water, it enters the water outlet 212 and the bypass water outlet 213 through the mixed water outlet 2143; pressing the switch valve core 41 can open or close the water outlets on the water outlet 212 and the bypass water outlet 213, thereby controlling the mixed water in the water outlet 212 to enter the external water outlet pipe through the first water outlet 123 and the second water outlet 124 and flow out from the overhead shower and hand shower, or controlling the mixed water in the bypass water outlet 213 to flow out from the bypass water outlet 2132.

[0076] By using the pre-embedded water outlet valve assembly of this embodiment, and pre-embedded box group 1 with two water inlets and two water outlets, a water outlet valve with two water inlets and four water outlets can be realized. In this embodiment, the pre-embedded box group 1 is provided with a bypass clearance groove 131 for accommodating the valve body 21 with an additional bypass water outlet pipe 2132. The pre-embedded box group 1 is fixedly installed in the wall, so if the number of water outlets needs to be changed, there is no need to dismantle the wall and re-lay the pre-embedded box group 1. For example, in other embodiments, the valve body 21 can be replaced with a valve body 21 with only one water outlet in the bypass water channel 213, such as... Figure 11 As shown, or replace it with a valve body 21 without bypass water passage 213, such as Figure 12 As shown, this allows users to freely select and change the number of water outlets of the outlet valve to two, three, four, or even more without changing the pre-embedded box group 1.

[0077] Because the mixing valve assembly 3 is modularly connected to the valve body 21 via the mixing valve seat 214, such as Figure 11 As shown, in other embodiments, the manually adjustable mixing valve core 31 can be replaced with an automatically adjustable thermostatic valve core, allowing users to easily select and replace it modularly according to their needs.

[0078] Therefore, by adopting the technical solution of the present invention, it is convenient to modularize each valve body 21 component into a standard product, and minimize the coherence between the components. In particular, after the pre-embedded box group 1 is used as the basic component of the shower system, the selection of the valve body 21 structure is no longer limited to the pre-embedded box group 1.

[0079] Example 2.

[0080] The main difference between this embodiment and Embodiment 1 lies in the composition of the water valve assembly 2. For example... Figures 13 to 15As shown, the pre-buried outlet valve assembly of the embodiment, wherein the pre-buried box group 1, the water mixing valve group 3 and the combined valve group 4 are completely same as those in embodiment 1, the difference is that the water passing valve group 2 of the embodiment includes a valve body 21, a connecting body 22 and a box body 23.

[0081] The water inlet channel 211, the water outlet channel 212, the bypass water channel 213, the water mixing valve seat 214 and the valve core seat 216 of the valve body 21 are same as those in the valve body 21 of embodiment 1 in structure and function, and will not be described here.

[0082] In the embodiment, the water passing valve group 2 is arranged outside the pre-buried box group 1, and the water inlet channel and the water outlet channel of the pre-buried core 12 are connected to the water inlet channel 211 and the water outlet channel 212 of the valve body 21 through the connecting body 22. Specifically, the connecting body 22 is provided with a secondary water inlet channel including a third water inlet channel 221 and a fourth water inlet channel 222, a secondary water outlet channel including a third water outlet channel 223 and a fourth water outlet channel 224, and a third water passing valve seat 225. The third water passing valve seat 225 is same as the second water passing valve seat 215 in embodiment 1 in structure and function, and is provided with a water inlet 2151, a water outlet 2152, a sealing groove 2153 and a sealing ring 2154 for adaptive connection with the first water passing valve seat 125 of the pre-buried box group 1. The third water inlet channel 221 forms a water channel communication between the cold water channel 121 of the pre-buried core 12 and the cold water inlet channel of the valve body 21; the fourth water inlet channel 222 forms a water channel communication between the hot water channel 122 of the pre-buried core 12 and the hot water inlet channel of the valve body 21; the third water outlet channel 223 and the fourth water outlet channel 224 form water channel communications between the first water outlet channel 123 and the second water outlet channel 124 of the pre-buried core 12 and the water outlet channel 212 of the valve body 21, respectively, so as to guide the cold water and the hot water entering through the pre-buried box group 1 into the cold water inlet channel and the hot water inlet channel of the valve body 21 through the third water inlet channel 221 and the fourth water inlet channel 222, and guide the mixed water of the water outlet channel 212 of the valve body 21 out of the water passing valve group 2 through the third water outlet channel 223 and the fourth water outlet channel 224, and then into the water outlet pipe through the pre-buried box group 1.

[0083] By using the water channel bridging effect of the connecting body 22 on the pre-buried box group 1 and the valve body 21, the valve body 21 can be arranged outside the box cavity 13 of the pre-buried box group 1, so as to connect the water inlet channel of the pre-buried core 12 through the secondary water inlet channel of the connecting body 22, connect the water outlet channel of the pre-buried core 12 through the secondary water outlet channel of the connecting body 22, and use the extension of the connecting body 22 to connect the valve body 21 to the pre-buried box group 1 outside the box cavity 13 of the pre-buried box group 1. The installation position of the valve body 21 of the water passing valve group 2 exceeds the wall surface, the valve body 21 becomes an exposed valve body 21, and the outlet device is changed from a concealed installation to an exposed installation without changing the installation of the pre-buried box group 1.

[0084] Embodiment 3.

[0085] The embodiment provides a shower water outlet system adopting the pre-buried water outlet valve assembly of the embodiment 1. As shown in FIG. 16, the external water pipe 6 is inserted into the connecting ring groove 128 between the hot-melt outer pipe 126 and the positioning inner pipe 127, and is connected to the pre-buried box group 1 through the hot-melt process to realize the hot-melt sealing connection, for guiding cold water and hot water into the pre-buried water outlet valve assembly, and conveying the mixed water to a top spray (not shown in the figure) and a shower head (not shown in the figure).

[0086] As Figures 17 to 18 shown, when the pre-buried box group 1 and the external water pipe 6 have been pre-buried in the wall, only a waterway connecting piece 8 matched with the pre-buried box group 1 is needed to connect the cold water channel 121 and the hot water channel 122 of the pre-buried core 12 to the water inlet channels of the exposed wall-mounted faucet, and the concealed shower system can still be changed into the exposed shower system.

[0087] As shown in the above embodiments, the modular pre-buried water outlet valve assembly of the present application only needs to pre-bury the pre-buried box group in the wall during the pre-buried stage of the shower system, and connect the water inlet pipe and the water outlet pipe, so that the user can still freely choose to continue to use the concealed shower system or change it into the exposed shower system after the wall of the bathroom is decorated, without the need to destroy the wall and re-arrange the water pipe. At the same time, the user can also change the valve body style according to the actual needs, and switch the number of water outlet channels without obstacles, to facilitate the increase of functional water outlet channels.

[0088] The above description of the specification and the embodiments is used to explain the protection scope of the present application, but does not constitute a limitation on the protection scope of the present application. Through the inspiration of the present application or the above embodiments, the modification, equivalent replacement or other improvement of the embodiments of the present application or one part of the technical features can be obtained by the ordinary skilled in the art combining with the common knowledge, the ordinary technical knowledge in the art and / or the prior art through logical analysis, reasoning or limited test, which should be included in the protection scope of the present application.
