Description

Technical Field

[0001] This invention relates to the field of bathroom product technology, and in particular to a switching valve and shower head set. Background Technology

[0002] Commercially available shower sets typically include a faucet, a handheld showerhead, and an overhead showerhead. A switching valve connects to each of these components, allowing users to switch between the different water paths. Users adjust the switching valve to select the appropriate water flow mode. In existing technology, push-button switching valves have multiple buttons corresponding to different water flow modes. Users press a button to select the appropriate mode. However, when switching modes, users must first pull out the original button to reset it, and then press another button. This repetitive process creates a gap between resetting and reselecting, resulting in an inconvenient and unsatisfactory user experience. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a switching valve that can reset the original button while a new button is pressed, making operation simple and smooth.

[0004] The present invention also proposes a shower head set having the above-mentioned switching valve.

[0005] A switching valve according to a first aspect of the present invention includes:

[0006] The housing defines a first accommodating cavity, an inlet, and an outlet, both of which are connected to the first accommodating cavity;

[0007] The diverter is disposed in the first accommodating cavity and defines three water outlet channels that connect to the water outlet and three installation channels that connect to the water inlet. Each installation channel is connected to the corresponding water outlet channel.

[0008] Three movable components are provided, which are inserted through the installation channel and slidably connected to the diverter. Each movable component has a closed position and an open position. In the closed position, the movable component isolates the water inlet and the water outlet channel. In the open position, the water inlet and the water outlet channel are connected.

[0009] The adapter includes a first main body and three connecting parts. The first main body is movably connected to the diverter, and the three connecting parts are slidably connected to each of the movable parts.

[0010] When any one of the movable parts moves to the open position, the adapter can drive the other two movable parts to move to the closed position.

[0011] The switching valve according to embodiments of the present invention has at least the following advantages: In this embodiment, the switching valve allows only one movable element to be in the open position, while the other two movable elements are in the closed position, and only one water path is open within the switching valve. Furthermore, when a change in the water outlet mode is required, the movement of one movable element toward the open position can drive the movement of the other movable elements, causing the movable element originally in the open position to move to the closed position, while the other movable element originally in the closed position remains in the closed position. Compared to the prior art where the reset and selection steps are separate, requiring the user to complete two steps, in this embodiment, when switching the water outlet mode, only the target button needs to be pressed to achieve reset and selection. The water outlet mode switching is completed with only one press operation, which is faster than the prior art.

[0012] According to some embodiments of the present invention, the direction in which the movable member moves from the closed position to the open position is defined as a first direction, and the direction in which it moves from the open position to the closed position is defined as a second direction. One of the three movable members is connected to a first elastic member, which can drive the movable member to move along the first direction. The other two movable members are connected to second elastic members, which can drive the movable member to move along the second direction.

[0013] According to some embodiments of the present invention, the inner wall of the installation channel is provided with a first communication port communicating with the water outlet channel, and the installation channel also has a second communication port communicating with the water inlet. The movable member includes a first sealing part capable of sealingly connecting with the inner wall of the installation channel.

[0016] According to some embodiments of the present invention, the movable member further includes a third sealing part that is sealed to the second mounting channel. The third sealing part separates the second mounting channel into a second receiving cavity. The cavity wall of the second receiving cavity is provided with an air pressure balance hole that communicates with the external environment. The direction in which the movable member moves from the closed position to the open position is set as a first direction, and the direction in which it moves from the open position to the closed position is set as a second direction.

[0017] The first sealing part and the third sealing part have a first pressure-bearing surface that can be subjected to water pressure along the first direction and a second pressure-bearing surface that can be subjected to water pressure along the second direction, wherein the area of ​​the first pressure-bearing surface is larger than the area of ​​the second pressure-bearing surface.

[0018] According to some embodiments of the present invention, the cavity wall of the second accommodating cavity extends along the movable member to form an abutment protrusion, the abutment protrusion being able to abut against the end face of the movable member, and the switching valve further includes a second elastic member, the second elastic member being sleeved on the abutment protrusion, and the two ends of the second elastic member abutting against the end face of the movable member and the cavity wall of the second accommodating cavity, respectively.

[0019] According to some embodiments of the present invention, the water outlet channel includes a first water outlet channel defined by the first main body and a second water outlet channel defined by the second main body. The second main body further includes a support portion, the second water outlet channel being disposed through the support portion. The support portion extends axially to abut against the first main body to define the water passage gap between the first main body and the second main body, and to connect the second water outlet channel and the first water outlet channel.

[0020] According to some embodiments of the present invention, the first main body extends radially into three connecting arms, the connecting portion being disposed at the free end of the connecting arms, and each of the connecting arms being evenly distributed circumferentially on the first main body.

[0046] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0051] In existing technology, push-button switching valves have multiple buttons 130 corresponding to different water outlet modes. Users can select the appropriate water outlet mode by pressing the button 130. However, when a user wants to switch water outlet modes, they must first pull out the original button 130 to reset it, and then press another button 130. This means that when a user wants to switch water outlet modes while showering, they need to stop the original water outlet mode before selecting a new one. There is a certain operational gap between the two water outlet modes, which can cause the shower set to experience water flow interruption. Furthermore, the method of resetting before selecting is cumbersome and inconvenient, resulting in a poor user experience.

[0052] To address the aforementioned problems, a switching valve is proposed in the first aspect of this application, such as... Figure 1 and Figure 2As shown, the switching valve includes a housing 100, a flow divider 200, a movable part 300, and a transition part 400. The housing 100 of this application defines a first accommodating cavity, an inlet 110, and an outlet 120 (e.g., ...). Figure 7 (As shown). Both the inlet 110 and the outlet 120 are connected to the first receiving cavity. The diverter 200 is disposed within the first receiving cavity, and the interior of the diverter 200 defines three outlet channels 230 and three installation channels 240, as shown. Figures 4 to 6 As shown, the water outlet channel 230 is connected to the water outlet 120, and the installation channel 240 is connected to the water inlet 110. Furthermore, each installation channel 240 is connected to its corresponding water outlet channel 230, as shown below. Figure 9 In the illustrated embodiment, a through groove is provided on the side wall at the top of the water outlet channel 230, extending through to the side wall of the corresponding installation channel 240, thereby achieving communication between the water outlet channel 230 and the installation channel 240. Three movable members 300 are respectively inserted into the corresponding installation channels 240 and slidably connected to the diverter 200, capable of sliding axially relative to the diverter 200 to a closed position and an open position. In the closed position, the movable member 300 isolates the water inlet 110 and the water outlet channel 230, preventing water from flowing from the water inlet 110 through the installation channel 240 and the water outlet channel 230 to the water outlet 120. In the open position, the water inlet 110 and the water outlet channel 230 are connected, allowing water to flow from the water inlet 110 through the installation channel 240 and the water outlet channel 230 to the water outlet 120.

[0053] It should be noted that, Figure 4 and Figure 6 In the structure shown, the movable part 300 is in the open position. Figure 5 In the structure shown, the movable component 300 is in the closed position. For ease of subsequent description, the direction in which the movable component 300 moves from the closed position to the open position is defined as the first direction 600, and the direction in which it moves from the open position to the closed position is defined as the second direction 610. Figure 4 In the embodiment shown, the first direction 600 is the downward direction, and the second direction 610 is the upward direction.

[0054] like Figure 2 As shown, the adapter 400 includes a first main body 410 and three connecting parts 421. The first main body 410 is movably connected to the diverter 200. The movable connection can be as follows: Figure 4 The ball joint shown is an example of a ball joint. Three connecting parts 421 are movably connected to three movable members 300. The included angle between adjacent connecting parts 421 and the central axis is greater than 90°, meaning that when one connecting part 421 is pressed down, the other two connecting parts 421 will rise. Figure 2As shown, the movable member 300 has an annular groove, and the connecting part 421 engages in the annular groove, allowing the movable member 300 to slide axially within the annular groove. When the first connecting part 421 abuts against the lower sidewall of the annular groove, the second and third connecting parts 421 abut against the upper sidewall of their respective annular grooves. Combined with the movement of the movable member 300, when any one of the movable members 300 moves to the open position, the adapter 400 can drive the other two movable members 300 to move to the closed position.

[0055] Combination such as Figures 1 to 3 The illustrated embodiment is described in detail. Each movable component 300 is connected to a button 130, allowing the user to apply force to the movable component 300 via the button 130 to move it up or down. When the three movable components 300 are moved to the open position, the shower set can display different water flow patterns. For example, when the first movable component 300 is moved to the open position, the handheld shower head of the shower set provides side water flow; when the second movable component 300 is moved to the open position, the overhead shower head provides top water flow; and when the third movable component 300 is moved to the open position, the faucet of the shower set provides bottom water flow. Figure 3 As shown, button 130 is marked with different water flow modes for easy identification by the user. To ensure sufficient water pressure, the shower set can only select one water flow mode at a time, meaning that only one water path is connected in the switching valve at any given time.

[0056] When a user needs to switch shower modes during a shower, taking the switch from overhead shower to handheld shower as an example, the original state is that the third movable part 300 is in the open position, while the second and first movable parts 300 are both in the closed position. The user presses the button 130 on the second movable part 300, causing it to move down until the movable part 300 reaches the open position. During the downward movement of the second movable part 300, the connecting part 421 corresponding to the third movable part 300 moves synchronously with the third movable part 300 until the third movable part 300 moves to the closed position. Since the first movable part 300 was originally in the closed position, the connecting part 421 corresponding to the first movable part 300 moves relative to the first movable part 300.

[0057] Based on the above, the switching valve in this embodiment allows only one movable element 300 to be in the open position, while the other two movable elements 300 are in the closed position, and only one water path is open within the switching valve. Furthermore, when changing the water outlet mode, the movement of one movable element 300 toward the open position can drive the movement of the other movable elements 300, causing the movable element 300 originally in the open position to move to the closed position, while the other movable element 300 originally in the closed position remains in the closed position. Compared to the prior art where the reset and selection steps are separate, requiring the user to complete two steps, in this embodiment, when switching the water outlet mode, only the target button 130 needs to be pressed to achieve reset and selection. The water outlet mode switching is completed with only one press operation, which is much faster than the prior art.

[0058] In some embodiments, such as Figure 2 , Figures 4 to 6 As shown, one of the three movable parts 300 is connected to a first elastic element 500, which can drive the movable part 300 to move along a first direction 600. The other two movable parts 300 are connected to second elastic elements 510, which can drive the movable part 300 to move along a second direction 610. Figure 6 In the illustrated embodiment, the first elastic member 500 is disposed at the upper end of the corresponding movable member 300, and can drive the movable member 300 to move to the open position so that water can flow out through the corresponding water outlet channel 230. Figure 4 and Figure 5 As shown, the second elastic element 510 is disposed at the lower end of the corresponding movable element 300, and can drive the movable element 300 to move to the closed position so that water cannot flow out through the corresponding water outlet channel 230. For ease of description, the movable element 300 connected to the first elastic element 500 is named the first movable element 301, and the movable element 300 connected to the second elastic element 510 is named the second movable element 302.

[0059] like Figures 4 to 6 As shown, Figure 4 and Figure 5 The diagrams show the second movable component 302 in the open and closed positions, respectively. Figure 6A schematic diagram shows the first movable member 301 in the open position. When the external water valve is opened, the user presses the second movable member 302 along the first direction 600, so that the pressure of the second movable member 302 along the first direction 600 is greater than the elastic force in the second direction 610. Therefore, the second movable member 302 moves down to the open position, while the first movable member 301 moves up to the closed position. At this time, the water outlet channel 230 corresponding to the second movable member 302 is open, and the water outlet channel 230 corresponding to the first movable member 301 is closed. The water pressure in the switching valve keeps the second movable member 302 in the open position, and the corresponding water outlet channel 230 remains open, allowing the user to shower. After showering, the user closes the external water valve, and the water pressure in the switching valve drops rapidly. The second movable member 302 is driven by the second elastic member 510 to move to the closed position, and the first movable member 301 is driven by the first elastic member 500 to move to the open position, so that the switching valve is in the normally open state of the water outlet channel 230 corresponding to the first movable member 301 when there is no water.

[0060] By setting the first elastic element 500 and the second elastic element 510, when the external water valve is closed, one movable element 300 of the switching valve is fixed in the open position, while the other movable elements 300 are in the closed position, thus achieving the reset of the switching valve. The water outlet channel 230 corresponding to the first movable element 301 is connected to a lower water outlet device such as a faucet, so that the switching valve remains in the faucet-open state. When the external water valve is opened, it will default to the faucet being open, preventing the user from getting wet when the water valve is opened again due to the valve not being reset after the previous use of a high-level water outlet mode such as a handheld shower or overhead shower.

[0061] In some embodiments, such as Figure 9 As shown, the inner wall of the installation channel 240 is provided with a first connecting port 243 communicating with the water outlet channel 230. The installation channel 240 also has a second connecting port 244 communicating with the water inlet 110. The movable member 300 includes a first sealing part 310 capable of sealingly connecting with the inner wall of the installation channel 240. When the movable member 300 is in the closed position, the first sealing part 310 isolates the first connecting port 243 and the second connecting port 244. When the movable member 300 is in the open position, the first connecting port 243 and the second connecting port 244 are connected. Figure 5In the illustrated embodiment, when the movable member 300 moves to the closed position, the first sealing part 310 blocks the second communication port 244 of the mounting channel 240, thereby disconnecting the first communication port 243 and the second communication port 244. In other embodiments, when the movable member 300 moves to the closed position, the first sealing part 310 may also block the second communication port 244, thereby disconnecting the first communication port 243 and the second communication port 244; or in other embodiments, when the movable member 300 moves to the closed position, the first sealing part 310 moves between the first communication port 243 and the second communication port 244, thereby disconnecting the first communication port 243 and the second communication port 244.

[0062] In some embodiments, such as Figures 2 to 6 As shown, the movable component 300 also includes a second sealing part 320 and a third sealing part 330 that are sealingly connected to the inner wall of the mounting channel 240. Along the first direction 600, the second sealing part 320, the second connecting port 244, and the third sealing part 330 are sequentially arranged; that is, the second sealing part 320 and the third sealing part 330 are located on both sides of the second connecting port 244, serving to seal and prevent water leakage. Figure 6 In the illustrated embodiment, the second sealing part 320 is disposed at the upper end of the movable member 300, enabling a sealed connection between the movable member 300 and the first mounting channel 241 to prevent water leakage from the button 130. The third sealing part 330 is disposed at the lower end of the movable member 300, enabling a sealed connection between the movable member 300 and the second mounting channel 242 to prevent water leakage from the pressure balance hole 246 of the second accommodating cavity 245. The second sealing part 320 includes a first sealing ring 321, and the third sealing part 330 includes a second sealing ring 331. Figures 4 to 6 In the illustrated embodiment, both the first sealing ring 321 and the second sealing ring 331 are Y-shaped sealing rings. The outer diameter of the first sealing ring 321 gradually increases along the first direction 600, while the outer diameter of the second sealing ring 331 gradually decreases along the first direction 600. When the external water valve is opened and the channel between the second sealing part 320 and the third sealing part 330 is filled with water, the flanges of the Y-shaped sealing ring open under water pressure, increasing the contact area with the inner wall of the mounting channel 240, thereby improving the sealing performance of the first sealing ring 321 and the second sealing ring 331. When the external water valve is closed, the flanges of the Y-shaped sealing ring return to their original shape, and the contact area with the inner wall of the mounting channel 240 is smaller, thus facilitating the movement of the movable part 300.

[0063] In some embodiments, such as Figures 2 to 6As shown, to reduce the manufacturing difficulty of the diversion component 200, it is manufactured in separate parts. The diversion component 200 includes a first main body 210 and a second main body 220, which are respectively sealed to the inner wall of the first accommodating cavity. The first main body 210 and the second main body 220 are spaced apart, and a water passage gap 250 communicating with the inlet 110 is defined at their midpoint. The installation channel 240 includes a first installation channel 241 defined by the first main body 210 and a second installation channel 242 defined by the second main body 220. The three installation channels 240 include three first installation channels 241 and three second installation channels 242, which are spaced apart. At their intervals, the first installation channels 241 and 242 communicate with the water passage gap 250, wherein the first installation channel 241 communicates with the outlet channel 230 through a first connecting port 243. The movable part 300 includes a first sealing part 310, which is located in the water passage gap 250 and can be moved to block the first installation channel 241 so that water cannot flow out from the first installation channel 241 and the corresponding water outlet channel 230.

[0064] In some embodiments, such as Figure 5 As shown, the third sealing part 330 separates the second mounting channel 242 into a second receiving cavity 245. The second receiving cavity 245 is located at the lower end of the second mounting channel 242. The cavity wall of the second receiving cavity 245 is provided with a pressure balancing hole 246 that communicates with the external environment (e.g., Figure 7 As shown), the pressure in the second accommodating cavity 245 is balanced with the external pressure, and due to the sealing effect of the third sealing part 330, water cannot enter the second accommodating cavity 245 through the third sealing part 330.

[0065] like Figure 4As shown, both the first sealing part 310 and the third sealing part 330 protrude from the main body of the movable member 300. Along the axial direction of the movable member 300, the first sealing part 310 and the third sealing part 330 each have two end faces. Since the lower end face of the third sealing part 330 is the wall of the second accommodating cavity 245 and does not contact water, it does not bear water pressure. The other three end faces all bear water pressure. For ease of description, the end face facing the first direction 600 is named the first pressure-bearing surface 340, which bears water pressure in the first direction 600. The end face facing the second direction 610 is named the second pressure-bearing surface 341, which bears water pressure in the second direction 610. The area of ​​the first pressure-bearing surface 340 is larger than the area of ​​the second pressure-bearing surface 341. Therefore, when the movable member 300 moves to the open position, the water pressure in the first direction 600 is greater than the water pressure in the second direction 610, thus keeping the movable member 300 in the open position. When the movable part 300 is connected to the second elastic part 510, the area of ​​the first pressure-bearing surface 340 and the area of ​​the second pressure-bearing surface 341 should be reasonably designed so that the pressure difference is greater than the elastic force of the second elastic part 510, thereby keeping the movable part 300 in the open position.

[0066] In some embodiments, such as Figure 5 As shown, the cavity wall of the second accommodating cavity 245 extends along the second direction 610 to form an abutment protrusion 247. The abutment protrusion 247 can abut against the end face of the movable member 300, thereby forming a limit position. That is, when the movable member 300 moves to the open position, the end face of the movable member 300 abuts against the abutment protrusion 247, and the displacement of the movable member 300 along the first direction 600 is restricted. The second elastic member 510 is disposed in the second accommodating cavity 245 and sleeved on the abutment protrusion 247. Thus, when the second elastic member 510 contracts or extends, the abutment protrusion 247 can prevent the second elastic member 510 from deflecting or tipping. The two ends of the second elastic member 510 abut against the end face of the movable member 300 and the cavity wall of the second accommodating cavity 245, respectively, and can drive the movable member 300 to move in the second direction 610. Furthermore, when the movable member 300 moves to the open position and the abutting protrusion 247 abuts against the movable member 300, there is still a certain gap between the end face of the movable member 300 and the lower end face of the second accommodating cavity 245 to accommodate the second elastic member 510.

[0067] In some embodiments, such as Figure 5 and Figure 8As shown, the water outlet channel 230 includes a first water outlet channel 231 defined by a first main body member 210 and a second water outlet channel 232 defined by a second main body member 220. The second main body member 220 also includes a support portion 221. The second water outlet channel 232 is disposed through the support portion 221. The support portion 221 extends along the second direction 610 to abut against the first main body member 210, so as to define a water passage gap 250 between the first main body member 210 and the second main body member 220, and to connect the second water outlet channel 232 and the first water outlet channel 231.

[0068] In some embodiments, such as Figure 2 As shown, the first main body 410 extends radially with three connecting arms 420. One end of the connecting arm 420 is connected to the first main body 410, and the other end extends to a free end. A connecting part 421 for movably connecting with the movable member 300 is provided at the free end of the connecting arm 420. Each connecting arm 420 is evenly distributed circumferentially on the first main body 410. When one connecting arm 420 descends or rises, the other two connecting arms 420 rise or descend by the same amount.

[0069] The second aspect of this application also proposes another switching valve, including a housing 100, a diverter 200, and three movable members 300. The diverter 200 is located within a first accommodating cavity of the housing 100 and defines three water outlet channels 230. The two ends of each water outlet channel 230 are connected to an inlet 110 and an outlet 120, respectively. Each movable member 300 passes through a water outlet channel 230 and is slidably connected to the diverter 200. The movable member 300 can move relative to the diverter 200 to a closed position and an open position. When the movable member 300 is in the closed position, its sealing portion closes the water outlet channel 230; when the movable member 300 is in the open position, its sealing portion opens the water outlet channel 230. The adapter 400 includes a first main body 410 and three connecting portions 421. The first main body 410 is movably connected to the diverter 200, specifically, by a ball joint. The three connecting members are slidably connected to the movable members 300. Furthermore, when any one of the movable parts 300 moves to the open position, the adapter 400 drives the other two movable parts 300 to move to the closed position, so that only one waterway in the diverter 200 is open.

[0070] The third aspect of this application also proposes a shower set, including an overhead shower, a handheld shower, a faucet, and a switching valve mentioned in any of the above embodiments. The water outlet channel 230 of the switching valve is connected to the overhead shower, the handheld shower, and the faucet respectively. Through the setting of the adapter 400, only one water path can be connected at any given time. Thus, only one of the overhead shower, the handheld shower, and the faucet can output water at any given time, achieving centralized water supply. Furthermore, the switching of the water output mode is relatively simple and quick, which can greatly improve the user experience.

[0071] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
