Description

Technical Field

[0001] This invention belongs to the technical field of bathroom products, specifically relating to a water valve body adapted to a pre-embedded box assembly and a concealed water valve. Background Technology

[0002] In existing water outlet device technologies using pre-embedded box assemblies, the water valve body adapted to the pre-embedded box assembly typically has an inlet path that matches the cold water inlet and hot water inlet of the pre-embedded box assembly, as well as an outlet path for the mixed cold and hot water. Simultaneously, depending on the outlet path configuration of the pre-embedded box assembly, outlets connected to each outlet path are installed on the outlet path to achieve water output from each outlet path. If the number of outlet paths needs to be increased, the pre-embedded box assembly model with the required outlet path function must be selected during installation. After the pre-embedded box assembly is installed, it is difficult to change the number of outlet paths, and the functionality of the water outlet device cannot be increased by adding outlet paths.

[0003] However, as consumers' demands for bathroom shower systems have increased, more and more functional water outlet devices have been designed, making the drawbacks of existing water outlet devices with pre-embedded boxes increasingly apparent. Because it requires knocking down already renovated walls and re-embedding and laying pipes, it greatly limits consumers' ability to upgrade and creates obstacles to enhancing their experience.

[0006] Preferably, the bypass water path is further provided with a bypass water outlet pipe, which extends from the bypass water outlet and is located on the side of the water passage valve seat. The water passage valve body is connected to an external water outlet device through the bypass water outlet pipe to guide the bypass water path outflow.

[0007] Preferably, the water valve seat is provided with an inlet and an outlet; the water inlet path is adapted to and connected to the water inlet channel of the pre-embedded box assembly through the water inlet, and the water outlet path is adapted to and connected to the water outlet channel of the pre-embedded box assembly through the water outlet.

[0008] Preferably, the water valve seat is provided with a sealing groove and a sealing ring. Each of the sealing grooves is opened along the outer periphery of the water inlet and the water outlet, so that the water valve body and the pre-embedded box assembly are sealed and connected by the sealing ring provided in the sealing groove.

[0009] Preferably, the water inlet path includes a cold water inlet path and a hot water inlet path, and is respectively connected to the cold water inlet channel and hot water inlet channel of the pre-embedded box assembly through the water inlet; the water valve body is provided with a mixing valve seat; the mixing valve seat is provided with a first water inlet, a second water inlet and a mixing outlet; the first water inlet is connected to the cold water inlet path, the second water inlet is connected to the hot water inlet path, and the mixing outlet is connected to the water outlet path.

[0011] Preferably, the valve core seat has an open cavity structure, and each open cavity is coaxially corresponding to the water outlet and the bypass water outlet.

[0012] Preferably, the bypass outlet pipe is rotatably connected to the bypass outlet so that the outlet position can be changed by rotating the bypass outlet pipe.

[0013] The invention also provides a concealed water valve, including a water valve body adapted to a pre-embedded box assembly as described above, and a mixing valve core; the water valve body is provided with a mixing valve seat, and the mixing valve core is installed on the mixing valve seat to control the mixing ratio of cold water and hot water, and output mixed water to the outlet.

[0014] Preferably, the concealed water valve further includes a switch valve core, the water valve body is provided with a valve core seat, and the switch valve core is installed on the valve core seat to control the opening and closing of the water outlet and the bypass water outlet.

[0015] 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:

[0016] (1) By using the water valve body of the present invention, by setting a bypass water passage that connects to the water outlet on the water valve body and setting a separate bypass water outlet, the water outlet can be directly formed from the water valve body without going through the pre-embedded box group. Therefore, without changing the pre-embedded box group that is compatible with it, by replacing the water valve body with different water outlets, a water outlet can be added to the water outlet device to meet the different water outlet function needs of users.

[0017] (2) A bypass water outlet pipe is directly installed in the bypass water circuit. The bypass water outlet pipe extends from the bypass water outlet, which facilitates the direct diversion of water from the bypass water outlet through the water valve body and facilitates the connection of other functional water circuit components.

[0018] (3) The water valve body is equipped with a mixing valve seat, which facilitates the installation of the mixing valve core. By adjusting the opening size of the first and second water inlets through the mixing valve core, the water volume ratio of the cold water and hot water circuits and the hot water inlet circuits entering the mixing chamber of the mixing valve core can be controlled, thereby controlling the mixing ratio of cold water and hot water, thus adjusting the temperature of the mixed water, and outputting the mixed water to the outlet circuit, making it easy to realize the outlet water temperature control of the outlet device;

[0019] (4) The design of the mixing valve seat is easy to adapt to various mixing valve cores. It can be adapted to manually temperature-adjustable mixing valve cores or thermostatic valve cores. Utilizing the memory metal characteristics in the thermostatic valve core, the size of the first and second inlets can be automatically adjusted according to the temperature of the mixed water, thereby automatically adjusting the temperature of the mixed water to achieve the effect of constant temperature water output, eliminating the need for temperature adjustment operation and making it convenient to use.

[0020] (5) The water valve body is provided with an inlet and an outlet to connect the inlet and outlet paths and the outlet and outlet paths respectively. This facilitates the separate setting of switch valve cores to control each outlet path by controlling the opening and closing of the outlet.

[0021] (6) The water valve body is provided with a valve core seat between the water outlet and the water outlet, and between the bypass water outlet and the bypass water outlet, for mounting the switch valve core, so as to facilitate the opening and closing control of the water outlet and the bypass water outlet; the independent valve core seat also allows users to freely choose and adapt to various types of switch valve cores.

[0022] (7) The valve core seat is designed with an open mouth structure. Each open mouth is coaxially corresponding to the water outlet and the bypass water outlet. The structure is simple and easy to install and adapt to various switch valve cores. This allows the switch valve core to control the connection status of the water outlet, the bypass water outlet and the water outlet pipe by controlling the opening and closing of the corresponding water outlet and the bypass water outlet, thereby controlling the water output.

[0023] (8) The design of the valve core seat makes it easy to adapt to various types of switch valve cores. For example, it can be adapted to push-button switch valves or rotary switch valves, providing users with different choices.

[0024] (9) A water valve seat is provided on the water valve body. The inlet and outlet are both located on the water valve seat, which facilitates the sealing and bonding connection between the water valve body and the pre-embedded box assembly. It also facilitates the modular design of the water valve body and the pre-embedded box assembly, making it convenient for installation and use.

[0025] (10) 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. Attached Figure Description

[0040] In the claims, description and accompanying drawings of this invention, the terms "comprising," "having," and variations thereof are used to mean "including but not limited to."

[0041] Example 1.

[0042] like Figures 1 to 4 As shown, the water valve body of this embodiment is provided with an inlet water passage 11, an outlet water passage 12 and a bypass water passage 13. On the front side of the water valve body, there is a mixing valve seat 14 for mounting the mixing valve core 4. On the rear side of the water valve body, there is a water valve seat 15 for connecting the pre-embedded box assembly 2.

[0043] The water inlet path 11 includes a cold water inlet path 111 and a hot water inlet path 112, with inlets 151 formed on the water valve seat 15. The mixing valve seat 14 is provided with a first inlet 141, a second inlet 142, and a mixing outlet 143. The first inlet 141 and the second inlet 142 are respectively connected to the cold water inlet path 111 and the hot water inlet path 112, and the mixing outlet 143 is connected to the outlet path 12 of the water valve body, so that the cold water and hot water that flow into the outlet valve through the pre-embedded box assembly 2 are mixed by the mixing valve core 4 and then output to the outlet path 12.

[0044] The water outlet 12 has two water outlets 152 on the water outlet valve seat, and forms a connected waterway with the first water outlet 223 and the second water outlet 224 of the pre-embedded box group 2 through the two water outlets 152, respectively, to deliver mixed water to the pre-embedded box group 2.

[0045] In this embodiment, the water passage valve body is also provided with a bypass water passage 13 connected to the water outlet passage 12. The bypass water passage 13 is provided with a bypass water outlet 131 and a bypass water outlet pipe 132 connected to the bypass water outlet 131. In this embodiment, the bypass water outlet 131 is located on the rear side of the water passage valve body, and the bypass water outlet pipe 132 is connected to the bypass water outlet 131 and extends rearward in a "U" shape to the side of the water passage valve seat 15, so that the bypass water passage 13 can directly discharge water from the valve body.

[0046] The water valve body is also provided with three valve core seats 16, which are respectively set to correspond to the two water outlets 152 on the water outlet 12 and the bypass water outlet 131 on the bypass water outlet 13, for mounting the switch valve core 3, so as to facilitate the opening and closing control of the water outlet 152 and the bypass water outlet 131. In this embodiment, the valve core seat 16 is set as an open cavity structure, and each open cavity is coaxially corresponding to the water outlet 152 and the bypass water outlet 131. The structure is simple and easy to install and adapt to various switch valve cores 3, so that each switch valve core 3 controls the opening and closing of the corresponding water outlet 152 and the bypass water outlet 131, thereby controlling the connection state of the water outlet 12, the bypass water outlet 13 and the water outlet pipe, and controlling the water output.

[0047] The outlet valve seat is also provided with a sealing groove 153 and a sealing ring 154. The sealing groove 153 is opened along the outer periphery of the inlet 151 and the outlet 152, and the sealing ring 154 is embedded in the sealing groove 153. When the water valve body is assembled with the pre-embedded box assembly 2, the sealing ring 154 forms a sealing effect between the inlet passage 11 and the inlet channel, and between the outlet passage 12 and the outlet channel.

[0048] Example 2.

[0049] See Figures 5 to 6 This embodiment provides a concealed water valve, including the water valve body 1 of embodiment 1, and also includes a switching valve core 2 and a mixing valve core 3.

[0050] When the water valve body 1 is assembled with the pre-embedded box assembly 2, the water valve body is housed within the box 21 of the pre-embedded box assembly 2 and is fitted and connected to the pre-embedded core 22 via the water valve seat 15. The cold water inlet 111 and the hot water inlet 112 are connected to the cold water channel 221 and the hot water channel 222 of the pre-embedded core 22 via the inlet 151 on the water valve seat 15, respectively. The outlet 12 is connected to the first outlet channel 223 and the second outlet channel 224 of the pre-embedded core 22 via the two outlets 152 on the water valve seat 15, respectively. The bypass outlet pipe 132 extends backward from the bypass outlet 131 on the water valve seat 15 into the bypass clearance groove 23 of the pre-embedded box assembly 2, and after a detour, water exits from the wall panel below the pre-embedded box assembly 2.

[0051] When the water valve body of this embodiment is assembled and used with the pre-embedded box assembly 2, the pre-embedded box assembly 2 inputs cold water and hot water into the cold water inlet 111 and hot water inlet 112 of the water valve body through the cold water channel 221 and hot water channel 222, respectively. The cold water and hot water enter the mixing valve core 4 from the first inlet 141 and the second inlet 142 of the mixing valve seat 14, respectively. After mixing in the mixing chamber of the mixing valve core 4, the water enters the outlet 12 through the mixing outlet 143. When the switch valve core 3 opens the corresponding outlet 152, the mixed water in the outlet 12 flows out from the outlet 152 and enters the first outlet 223 or the second outlet 224 of the pre-embedded core 22, and flows out to the external outlet pipe. When the switch valve core 3 closes the corresponding outlet 152, the mixed water cannot enter the pre-embedded core 22 through the outlet 152, and the corresponding outlet is closed to control the water output of each water circuit. The mixed water in the outlet water passage 12 enters the bypass outlet water pipe 132 from the bypass outlet 131 of the bypass water passage 13, and exits directly from the water valve body without passing through the pre-embedded box group 2.

[0052] In other embodiments, the water valve body may be provided with two bypass outlets 131 and two bypass outlet pipes 132 in the bypass water passage 13, such as... Figures 7 to 8 As shown, one of the bypass water outlet pipes 132 has the same structure as the bypass water outlet pipe 132 in the above embodiment, and the other bypass water outlet pipe 132 extends forward from the bypass water outlet 131 on the front side of the water valve body, and can be used to connect external water outlet faucets and other water circuit control devices.

[0053] Because the water-passing valve body adopts the structure of valve core seat 16 for mounting switch valve core 3, users can choose either push-button switch valve core 3 or knob switch valve core 3 according to their needs, without being limited by other structures of the water-passing valve body, thus providing users with more options for accessories.

[0054] As can be seen from the specific embodiments of the present invention described above, by setting a bypass water passage 13 connected to the water outlet passage 12 on the water valve body and setting a separate bypass water outlet 131, a water outlet passage can be directly formed from the water valve body without passing through the pre-embedded box group 2. Therefore, there is no need to change the pre-embedded box group 2 that is adapted to it. Even if the pre-embedded box group 2 has been laid and the wall has been decorated, there is no need to knock down the wall and re-lay the pre-embedded box group 2. By selecting and replacing water valve bodies with different numbers of bypass water passages 13 to adapt to the installed pre-embedded box group 2, a water outlet passage can be added to the water outlet device to meet the user's need to increase the functionality of the water outlet device by adding a water outlet passage.

[0055] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this invention, but does not constitute a limitation on the scope of protection of this invention. Modifications, equivalent substitutions, or other improvements to the embodiments of this invention 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 invention or the foregoing embodiments, in conjunction with common knowledge, general technical knowledge, and / or existing technology, should all be included within the scope of protection of this invention.
