[0002] Currently, existing multi-functional shower products typically include handheld showerheads, overhead showerheads, spray guns, and faucets to provide various water output functions. Multi-functional shower products generally incorporate a water circuit switching switch between the inlet water circuit and the multiple functional water circuits. This switch allows for the switching of the inlet water circuit to different functional water circuits, thereby enabling the switching of different water output functions.

[0003] Existing water circuit switching switches typically connect a handle to a water distribution plate inside the water circuit switching chamber, thereby controlling the rotation of the water distribution plate to switch between different functional water circuits. The water distribution plate is usually mounted on a rotating column inside the water circuit switching chamber. Under the pressure of the water distribution plate and the water flow, the connection between the rotating column and the inner wall of the water circuit switching chamber is prone to breakage due to stress concentration, resulting in damage to the water circuit switching switch that cannot be repaired by replacing parts. Summary of the Invention

[0004] This application provides a water circuit switching valve and a bathroom device to solve the problem that in the prior art, the rotating column used to fix the water distribution plate in the water circuit switching switch is prone to breakage due to stress concentration under the pressure of the water distribution plate and the water flow, which leads to damage to the water circuit switching switch and makes it impossible to repair by replacing parts.

[0005] To address the above problems, this application provides: a water circuit switching valve, comprising:

[0007] A water circuit switching assembly, located inside the water circuit switching cavity, includes a valve stem and a rotating component. The valve stem is connected to the rotating component, and both ends of the valve stem are rotatably inserted into the valve seat assembly. The rotating component is provided with a water passage hole.

[0008] The valve stem drives the rotating component to rotate so that the water passage hole can correspond to the position of at least one of the water outlet holes, so that the water inlet hole can communicate with at least one of the water outlet holes through the water passage hole.

[0014] In one possible implementation, the rotating member has a through hole along the axial direction of its rotation center axis, the valve stem passes through the through hole, the inner wall of the through hole is provided with a first positioning part, and the valve stem is provided with a second positioning part in the circumferential direction corresponding to the position of the first positioning part. The first positioning part and the second positioning part abut against each other so that the valve stem can drive the rotating member to rotate.

[0015] In one possible implementation, the water circuit switching assembly further includes a handle connected to a first end of the valve stem, and the handle is provided with a pointing portion;

[0016] The valve seat assembly is provided with multiple joints spaced apart along the rotation direction of the rotating member, and each joint is provided with a water outlet channel.

[0017] When the handle drives the rotating component to rotate via the valve stem, so that the pointing part corresponds to the position of a certain connector, the water passage is connected to the water inlet channel in that connector.

[0018] When the position of the pointing part corresponds to that of the two adjacent connectors, the water passage is connected to the water outlet in the two connectors respectively.

[0019] In one possible implementation, the handle has a resilient post on the side facing the valve seat assembly, and the abutting end of the resilient post elastically abuts against the valve seat assembly. The handle drives the resilient post to rotate, so that the abutting end slides against the valve seat assembly.

[0020] In one possible implementation, the valve seat assembly has a plurality of positioning grooves spaced apart along the rotation direction of the rotating member on the side near the handle;

[0021] When the abutting end is sequentially inserted into the positioning groove at different positions, the pointing part corresponds to the position of a certain connector or to the position between two adjacent connectors.

[0022] In one possible implementation, the second end of the valve stem is provided with a first limiting portion along its rotation direction, and the valve seat assembly is provided with a second limiting portion corresponding to the position of the first limiting portion.

[0023] The handle is provided with a third limiting part, and the valve seat assembly is provided with a fourth limiting part corresponding to the position of the third limiting part.

[0025] In one possible implementation, the water circuit switching valve further includes a fixed cover and a rotating member, the valve seat assembly and the fixed cover forming a receiving cavity, the rotating member being located within the receiving cavity, and one end of the rotating member being rotatably inserted through the fixed cover and connected to the socket, such that the fixed cover abuts against the rotating member and the socket.

[0026] In one possible implementation, the socket is provided with a fifth limiting part, and the fixed cover is provided with a sixth limiting part corresponding to the position of the fifth limiting part. The two opposite surfaces of the fifth limiting part along its rotation direction can respectively abut against the sixth limiting part to limit the maximum rotation angle range of the socket.

[0027] This application also provides a bathroom fixture, including the water circuit switching valve provided in any of the above embodiments.

[0028] The beneficial effects of this application are as follows: This application proposes a water circuit switching valve and a bathroom device. When in use, the user can rotate the valve stem, which in turn drives the rotating component inside the water circuit switching chamber to rotate. This allows the water passage holes of the rotating component to connect with water outlet holes at different locations, ultimately enabling the inlet channel to switch between different outlet channels through the water passage holes. Since the valve stem is connected to the rotating component and both ends of the valve stem are rotatably inserted into the valve seat assembly, the rotating component can be rotatably connected to the valve seat assembly by connecting to the valve stem. This rotatable connection between the two ends of the valve stem and the valve seat assembly improves the situation where the valve stem breaks due to stress concentration under the pressure of the rotating component and water flow. Furthermore, when the valve stem is damaged, the water circuit switching valve can be repaired by replacing the valve stem. Attached Figure Description

[0046] Example 1

[0047] Please see Figure 1 and Figure 2 This embodiment provides a water circuit switching valve applied to a bathroom fixture. The water circuit switching valve includes a valve seat assembly 100 and a water circuit switching assembly 200. The valve seat assembly 100 has a water circuit switching chamber 110, an inlet channel 120, and multiple outlet channels 130. The inlet channel 120 and the multiple outlet channels 130 are respectively connected to the water circuit switching chamber 110, and the inner wall of the water circuit switching chamber 110 is respectively provided with an inlet hole 121 communicating with the inlet channel 120 and an outlet hole 131 communicating with the outlet channels 130. The water circuit switching assembly 200 is located inside the water circuit switching chamber 110 and includes a valve stem 210 and a rotating member 220. The valve stem 210 is connected to the rotating member 220, and both ends of the valve stem 210 are rotatably inserted through the valve seat assembly 100. The rotating member 220 is provided with a water passage hole 221. The valve stem 210 drives the rotating component 220 to rotate so that the water passage 221 can correspond to the position of at least one water outlet 131, so that the water inlet 121 can be connected to at least one water outlet 131 through the water passage 221.

[0048] In use, the water circuit switching valve provided in the embodiments of this application allows the user to rotate the valve stem 210, thereby causing the rotating component 220 inside the water circuit switching chamber 110 to rotate. This allows the water passage hole 221 of the rotating component 220 to connect with the water outlet hole 131 at different positions, ultimately enabling the inlet channel 120 to switch between different outlet channels 130 through the water passage hole 221. Since the valve stem 210 is connected to the rotating component 220 and both ends of the valve stem 210 are rotatably inserted into the valve seat assembly 100, the rotating component 220 can be rotatably connected to the valve seat assembly 100 by connecting to the valve stem 210. This rotatable connection between the two ends of the valve stem 210 and the valve seat assembly 100 can improve the situation where the valve stem 210 breaks due to stress concentration under the pressure of the rotating component 220 and the water flow. Furthermore, when the valve stem 210 is damaged, the water circuit switching valve can be repaired by replacing the valve stem 210.

[0049] The different water outlets 130 can be connected to different bathroom appliances such as handheld shower heads, spray guns, overhead showers, and faucets.

[0050] like Figure 2 and Figure 3 As shown, in the above embodiment, optionally, the rotating member 220 includes a first disc portion 222, a connecting portion 223, and a second disc portion 224 connected sequentially along the axial direction of its rotation center axis. The valve stem 210 passes through the first disc portion 222, the connecting portion 223, and the second disc portion 224 sequentially. The first disc portion 222 is provided with a water passage hole 221. The two opposite sides of the first disc portion 222 and the second disc portion 224 respectively abut against the two opposite inner wall surfaces inside the water circuit switching cavity 110. The water inlet gap 225 between the first disc portion 222 and the second disc portion 224 corresponds to the position of the water inlet hole 121, so that the liquid entering the water circuit switching cavity 110 from the water inlet hole 121 can flow into the water passage hole 221 through the water inlet gap 225.

[0051] Specifically, when the water circuit switching valve is in use, the water flowing into the water circuit switching chamber 110 from the inlet hole 121 can flow into the water passage hole 221 through the inlet gap 225 between the first disc 222 and the second disc 224. During this process, the water flowing into the inlet gap 225 can generate opposite forces on the first disc 222 and the second disc 224, which can cancel each other out to a certain extent. This reduces the friction between the rotating component 220 and the inner wall surface of the water circuit switching chamber 110 where the outlet hole 131 is provided, thereby reducing the resistance when the valve stem 210 and the rotating component 220 rotate, making it easier for the user to operate the valve stem 210. The direction and magnitude of the force exerted on the rotating component 220 by the water flow can be changed by adjusting the area ratio of the first disc 222 and the second disc 224 in the cross-section perpendicular to their rotation axis. For example, when the area of ​​the first disc 222 is larger than that of the second disc 224, the force exerted by the water flow on the first disc 222 is greater than the force exerted on the second disc 224.

[0052] like Figure 3 and Figure 6 As shown, in the above embodiment, optionally, the water switching cavity 110 is also provided with a plurality of annular seals 230, and the edge of the water outlet 131 is provided with an annular groove 111, and each annular seal 230 abuts against the inner wall surface of the first disc portion 222 and the corresponding annular groove 111.

[0053] Specifically, an annular groove 111 can be formed on the edge of the water outlet 131 to fix the annular seal 230, and each annular seal 230 is respectively abutted between the first disc portion 222 and the inner wall surface of the corresponding annular groove 111. The annular groove 111 limits the position of the annular seal 230, preventing the annular seal 230 from shifting position under the friction of the rotating member 220. In addition, the setting of the annular seal 230 can improve the problem of liquid flowing through the water passage 221 and the water outlet 131 leaking from the gap between the rotating member 220 and the edge of the water outlet 131 and flowing into the remaining water outlet 131.

[0054] like Figure 6 As shown, in the above embodiment, optionally, adjacent annular seals 230 are connected to each other and integrally formed, and adjacent annular grooves 111 are interconnected.

[0055] Specifically, multiple adjacent annular seals 230 are interconnected and integrally formed, which can connect multiple annular seals 230 to form an irregular seal, thereby improving the structural strength of the irregular seal and increasing the friction between the irregular seal and the edge of the water outlet 131, which can reduce the problem of the irregular seal being driven by the rotating component 220 to a certain extent.

[0056] like Figure 2 and Figure 3 As shown, in the above embodiment, optionally, an installation groove 112 is provided on the side of the water circuit switching cavity 110 near the second plate portion 224, and the second plate portion 224 abuts against the installation groove 112.

[0057] Specifically, when the second disc 224 abuts against the mounting groove 112, the portion of the second disc 224 exposed outside the mounting groove 112 is reduced, thereby decreasing the resistance of the second disc 224 to the flow of liquid into the water inlet gap 225.

[0058] like Figure 3 and Figure 4 As shown, in the above embodiment, optionally, an elastic ring 113 is provided between the second disc portion 224 and the mounting groove 112.

[0059] Specifically, by providing an elastic ring 113 between the second disc portion 224 and the mounting groove 112, the sealing between the inner wall surfaces of the second disc portion 224 and the mounting groove 112 can be improved, thereby preventing liquid from flowing out of the valve seat assembly 100 from the water switching chamber 110 through the gap between the inner wall surfaces of the second disc portion 224 and the mounting groove 112.

[0060] like Figure 4 and Figure 5 As shown, in the above embodiment, optionally, the rotating member 220 has a through hole 226 extending along the axial direction of its rotation center axis, the valve stem 210 passes through the through hole 226, the inner wall surface of the through hole 226 is provided with a first positioning part 227, and the valve stem 210 is provided with a second positioning part 211 in the circumferential direction corresponding to the position of the first positioning part 227. The first positioning part 227 and the second positioning part 211 abut against each other so that the valve stem 210 can drive the rotating member 220 to rotate.

[0061] Specifically, a first positioning part 227 and a second positioning part 211 that can cooperate with each other can be provided on the inner wall surfaces of the valve stem 210 and the through hole 226, respectively. When the first positioning part 227 and the second positioning part 211 abut against each other, the rotating member 220 and the valve stem 210 can be limited, so that the valve stem 210 can drive the rotating member 220 to rotate. Furthermore, the provision of the first positioning part 227 and the second positioning part 211 can ensure that the valve stem 210 can only pass through the rotating member 220 at a certain rotation angle, which can play a foolproof role. The first positioning part 227 and the second positioning part 211 can be respectively configured as positioning protrusions, positioning ribs, positioning grooves, etc., which can play a role in limiting and positioning foolproof.

[0062] Example 2

[0063] like Figure 4 and Figure 5As shown, this embodiment, based on Embodiment 1, proposes a different arrangement for the handle 240. Optionally, in the above embodiment, the water circuit switching assembly 200 further includes a handle 240, which is connected to the first end 212 of the valve stem 210. The handle 240 has a pointing portion 241. The valve seat assembly 100 has multiple connectors 140 spaced apart along the rotation direction of the rotating member 220, each connector 140 containing a water outlet channel 130. When the handle 240 drives the rotating member 220 to rotate via the valve stem 210, so that the pointing portion 241 corresponds to the position of a certain connector 140, the water passage 221 communicates with the water inlet channel 120 within that connector 140. When the pointing portion 241 corresponds to the position between two adjacent connectors 140, the water passage 221 communicates with the water outlet channels 130 within those two connectors 140 respectively.

[0064] Specifically, by providing a pointing part 241 on the handle 240, when the pointing part 241 corresponds to the position of a certain connector 140, the handle 240 drives the rotating part 220 to rotate through the valve stem 210 until the water passage 221 connects with the corresponding water outlet 131, thereby connecting the water passage 221 with the water inlet channel 120 in the corresponding connector 140. When the pointing part 241 corresponds to the position between two adjacent connectors 140, that is, when the pointing part 241 points to the position between the two adjacent connectors 140, the handle 240 drives the rotating part 220 to rotate through the valve stem 210 until the water passage 221 connects with the two corresponding water outlets 131, thereby connecting the water passage 221 with the water inlet channel 120 in the corresponding connector 140. Therefore, the arrangement of the handle 240 and the pointing part 241 allows users to easily switch between different water outlet functions. The pointing part 241 can be a handle or an arrow marker, which allows the user to easily rotate the handle 240.

[0065] like Figure 5 and Figure 7 As shown, in the above embodiment, optionally, the handle 240 is provided with an elastic post 242 on the side facing the valve seat assembly 100. The abutting end of the elastic post 242 elastically abuts against the valve seat assembly 100. The handle 240 drives the elastic post 242 to rotate so that the abutting end slides against the valve seat assembly 100.

[0066] Specifically, the handle 240 is provided with an elastic post 242 on the side facing the valve seat assembly 100, and the abutting end of the elastic post 242 can elastically abut against the valve seat assembly 100. The elasticity of the elastic post 242 can improve the problem of noise caused by structural looseness between the handle 240 and the valve seat assembly 100, and improve the user's operating feel.

[0067] The elastic column 242 may include a spring and a column body, with the spring abutting against the column body and the handle 240.

[0068] like Figure 5 and Figure 7 As shown, in the above embodiment, optionally, the valve seat assembly 100 has a plurality of positioning grooves 150 spaced apart along the rotation direction of the rotating member 220 on the side near the handle 240. When the abutting end is sequentially inserted into the positioning grooves 150 at different positions, the pointing part 241 corresponds to the position of a certain connector 140 or to the position between two adjacent connectors 140.

[0069] Specifically, multiple positioning grooves 150 can be provided at intervals along the rotation direction of the rotating member 220 on the side of the valve seat assembly 100 near the handle 240. When the handle 240 is rotated until the abutting end of the elastic column 242 is engaged in different positioning grooves 150, the pointing part 241 corresponds to the position of a certain connector 140 or the position between two adjacent connectors 140, thereby allowing the water circuit switching valve to switch between different water output functions. Furthermore, during the rotation of the handle 240, when the elastic column 242 slides relative to the valve seat assembly 100 until its abutting end abuts into the positioning groove 150, the abutting end and the inner wall of the positioning groove 150 will collide, generating a prompt sound. This prompt sound can remind the user that the water output function has been switched to the next level.

[0070] like Figure 5 and Figure 8 As shown, in the above embodiment, optionally, the second end 213 of the valve stem 210 is provided with a first limiting portion 214 along its rotation direction, and the valve seat assembly 100 is provided with a second limiting portion 160 corresponding to the position of the first limiting portion 214. The two opposite surfaces of the first limiting portion 214 along its rotation direction can respectively abut against the second limiting portion 160 to limit the maximum rotation angle range of the valve stem 210; and / or the handle 240 is provided with a third limiting portion 243, and the valve seat assembly 100 is provided with a fourth limiting portion 170 corresponding to the position of the third limiting portion 243. The two opposite surfaces of the third limiting portion 243 along its rotation direction can respectively abut against the fourth limiting portion 170 to limit the maximum rotation angle range of the handle 240.

[0071] Specifically, when the two opposing surfaces of the first limiting portion 214 of the valve stem 210 along its rotation direction abut against the second limiting portion 160 of the valve seat assembly 100, the maximum rotation angle range between the valve stem 210 and the valve seat assembly 100 is limited, thereby allowing the valve stem 210 to control the maximum rotation angle range of the handle 240 according to the number and position of the water outlet holes 131. When the two opposing surfaces of the third limiting portion 243 of the handle 240 along its rotation direction abut against the fourth limiting portion 170 of the valve seat assembly 100, the maximum rotation angle range between the handle 240 and the valve seat assembly 100 is limited, thereby allowing the handle 240 to control its maximum rotation angle range according to the number and position of the water outlet holes 131. The first limiting portion 214, the second limiting portion 160, the third limiting portion 243, and the fourth limiting portion 170 can be configured as arc-shaped grooves, limiting protrusions, limiting ribs, or other limiting structures, depending on the actual situation.

[0072] Example 3

[0073] like Figure 1 , Figure 8 and Figure 9 As shown, this embodiment proposes a configuration method for the socket 300 based on Embodiment 1 or Embodiment 2. Optionally, in the above embodiments, the water circuit switching valve further includes a socket 300, which is rotatably connected to the side of the valve seat assembly 100 away from the handle 240.

[0074] Specifically, a socket 300, which can be used to fix bathroom accessories such as hand showers and spray guns, can be rotatably connected to the side of the valve seat assembly 100 away from the handle 240. This allows the water circuit switching valve to be used as a fixed bracket, and the user can adjust the water outlet angle of the hand shower or spray gun by adjusting the rotation angle of the socket 300.

[0075] like Figure 8 and Figure 9 As shown, in the above embodiment, optionally, the water circuit switching valve further includes a fixed cover 400 and a rotating member 500. The valve seat assembly 100 and the fixed cover 400 surround to form a receiving cavity 410.
