In the prior art, the push-type switching valve has a plurality of buttons 130 corresponding to different water outlet modes, and a user can select a proper water outlet mode by pressing the buttons 130, however, when the user wants to switch the water outlet mode, the user first needs to pull the original button 130 to reset and then select to press another button 130. This means that when a user is taking a shower, if he wants to switch the water outlet state, he needs to stop the original water outlet mode first, then he can select a new water outlet mode, and a certain operation gap exists between the two water outlet modes, so that the shower set can be cut off. Moreover, the switching mode of resetting and then selecting is complicated, the operation is troublesome, and the experience of a user is poor.

In order to solve the above-mentioned problems, in the first aspect of the present application, a switching valve is provided, which includes a housing 100, a flow dividing member 200, a movable member 300, and an adapter member 400, as shown in fig. 1 and 2. The housing 100 of the present application defines a first receiving chamber, a water inlet 110, and a water outlet 120 (as shown in fig. 7). Both the water inlet 110 and the water outlet 120 are in communication with the first receiving chamber. The flow dividing member 200 is disposed in the first accommodating cavity, and the inside of the flow dividing member 200 defines three water outlet channels 230 and three mounting channels 240, as shown in fig. 4 to 6, the water outlet channels 230 are communicated with the water outlet 120, the mounting channels 240 are communicated with the water inlet 110, and each mounting channel 240 is respectively communicated with the corresponding water outlet channel 230, as in the embodiment shown in fig. 9, a through groove is disposed on a sidewall of the top end of the water outlet channel 230, and the through groove penetrates through to a sidewall of the corresponding mounting channel 240, thereby realizing the communication between the water outlet channel 230 and the mounting channel 240. The movable members 300 are three in number, respectively penetrate through the corresponding mounting channels 240, are slidably connected with the flow dividing member 200, and can slide to a closed position and an open position relative to the flow dividing member 200 along the axial direction. When in the closed position, the movable member 300 blocks the water inlet 110 and the water outlet channel 230, so that water cannot flow from the water inlet 110 through the mounting channel 240 and the water outlet channel 230 and then out of the water outlet 120. In the open position, the water inlet 110 and the water outlet channel 230 are communicated, so that water can flow from the water inlet 110, through the mounting channel 240 and the water outlet channel 230, and then out of the water outlet 120.

It should be noted that, in the structure shown in fig. 4 and 6, the movable member 300 is in the open position, and in the structure shown in fig. 5, the movable member 300 is in the closed position. For convenience of the following description, the direction in which the movable member 300 moves from the closed position to the open position is set to be the first direction 600, and the direction in which the movable member moves from the open position to the closed position is set to be the second direction 610. In the embodiment shown in fig. 4, the first direction 600 is a downward direction and the second direction 610 is an upward direction.

As shown in fig. 2, the adaptor 400 includes a first body portion 410 and three connecting portions 421, where the first body portion 410 is movably connected to the shunt member 200, and the movable connection may be ball-hinged as shown in fig. 4. The three connecting portions 421 are movably connected with the three movable members 300, respectively. The included angle between the adjacent connecting portions 421 and the central axis is larger than 90 °, and when one connecting portion 421 is pushed down, the other two connecting portions 421 rise. As shown in fig. 2, the movable member 300 has a ring groove, and the connecting portion 421 is engaged in the ring groove, so that the movable member 300 can slide in the ring groove in the axial direction. When the first connecting portion 421 abuts against the lower side wall of the ring groove, the second connecting portion 421 and the third connecting portion 421 abut against the upper side wall of the corresponding ring groove. In combination with the movement of the movable members 300, when any one of the movable members 300 is moved to the open position, i.e., the adapter 400 can drive the other two movable members 300 to move to the closed position.

In connection with the embodiments shown in fig. 1 to 3, the movable member 300 is connected with buttons 130, respectively, and a user can apply force to the movable member 300 through the buttons 130 to move it downward or upward. When the three movable pieces 300 move to the opening position, the shower sets can respectively show different water outlet modes, for example, when the first movable piece 300 moves to the opening position, the hand shower of the shower set carries out side water outlet, when the second movable piece 300 moves to the opening position, the top shower of the shower set carries out top water outlet, and when the third movable piece 300 moves to the opening position, the tap of the shower set carries out lower water outlet. As shown in fig. 3, the buttons 130 are marked with marks for different water discharge modes to be distinguished by a user. In order to ensure enough water outlet pressure, the shower head set can only select one water outlet mode to carry out water outlet, namely, only one waterway is in a communicating state at the same time in the switching valve.

When a user needs to switch the shower mode in the shower process, taking the example of changing the top shower water outlet into the hand shower water outlet, the original state is that the third movable piece 300 is located at the open position, and the second movable piece 300 and the first movable piece 300 are both located at the closed position. The user presses the button 130 of the second movable member 300 to move the second movable member 300 downward to the open position, and in the process of moving the second movable member 300 downward, the connecting portion 421 corresponding to the third movable member 300 moves synchronously with the third movable member 300 until the third movable member 300 moves to the closed position, and since the first movable member 300 is originally located in the closed position, the connecting portion 421 corresponding to the first movable member 300 moves relative to the first movable member 300.

Based on the above, the switching valve in this embodiment can make one movable member 300 be located at the open position, and the other two movable members 300 be located at the closed position, and only one waterway is conducted in the switching valve. When the water outlet mode needs to be replaced, the movement of one movable member 300 towards the open position can drive the movement of the other movable member 300, so that the movable member 300 originally positioned at the open position moves to the closed position, and the other movable member 300 originally positioned at the closed position is kept at the closed position. Compared with the prior art that the steps of resetting and selecting are separated, the user needs to complete two steps of operations, and in the embodiment, the resetting and selecting can be achieved only by pressing the target button 130 when the water outlet mode needs to be switched, and the water outlet mode is switched only by one pressing operation, so that the method is more rapid than the prior art.

In some embodiments, as shown in fig. 2 and fig. 4 to fig. 6, one of the three movable members 300 is connected to a first elastic member 500, the first elastic member 500 can drive the movable member 300 to move along a first direction 600, the other two movable members 300 are connected to a second elastic member 510, and the second elastic member 510 can drive the movable member 300 to move along a second direction 610. In the embodiment shown in fig. 6, the first elastic member 500 is disposed at an upper end of the corresponding movable member 300, and is capable of driving the movable member 300 to move to the open position, so that water can flow out through the corresponding water outlet channel 230. As shown in fig. 4 and 5, the second elastic member 510 is disposed at the lower end of the corresponding movable member 300, and is capable of driving the movable member 300 to move to the closed position, so that the water cannot flow out through the corresponding water outlet channel 230. For convenience of description, the movable member 300 to which the first elastic member 500 is connected is named as a first movable member 301, and the movable member 300 to which the second elastic member 510 is connected is named as a second movable member 302.

As shown in fig. 4 to 6, fig. 4 and 5 show schematic views of the second movable member 302 in an open position and in a closed position, respectively, and fig. 6 shows a schematic view of the first movable member 301 in an open position. When the external water valve is opened, the user presses the second movable member 302 in the first direction 600, so that the pressure of the second movable member 302 in the first direction 600 is greater than the elastic force applied in the second direction 610, and thus the second movable member 302 moves down to the open position, and simultaneously 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 opened, and the water outlet channel 230 corresponding to the first movable member 301 is closed. The second movable member 302 is maintained at the open position by the water pressure in the switching valve, and the corresponding water outlet passage 230 is maintained at the open state, and the user performs a shower operation. After the shower is finished, the user closes the external water valve, the water pressure in the switching valve drops rapidly, the second movable piece 302 is driven by the second elastic piece 510 to move to the closed position, and the first movable piece 301 is driven by the first elastic piece 500 to move to the open position, so that the switching valve is in a state that the water outlet channel 230 corresponding to the first movable piece 301 is normally open in the anhydrous state.

By arranging the first elastic member 500 and the second elastic member 510, one fixed movable member 300 is kept at the open position when the external water valve is closed, and the other movable members 300 are all at the closed position, so that the reset of the switching valve is realized. The water outlet channel 230 corresponding to the first movable member 301 is connected with a lower water outlet device such as a faucet, so that the switching valve keeps a normal state of the faucet, when the external water valve is opened, the water outlet channel is default to be opened, and the situation that the user is wetted when the water valve is opened next time because the water outlet channel is not reset after the water outlet channel is used last time in a high-level water outlet mode such as water outlet of a handheld shower or water outlet of a top shower is avoided.

In some embodiments, as shown in fig. 9, a first communication port 243 communicating with the water outlet passage 230 is provided on an inner wall of the installation passage 240, the installation passage 240 further has a second communication port 244 communicating with the water inlet 110, and the movable member 300 includes a first sealing portion 310 capable of being sealingly connected with the inner wall of the installation passage 240. The first sealing portion 310 blocks the first and

second communication ports

243 and 244 when the movable member 300 is in the closed position, and the first and

second communication ports

243 and 244 communicate when the movable member 300 is in the open position. In the embodiment shown in fig. 5, when the movable member 300 moves to the closed position, the first sealing portion 310 is blocked from the second communication port 244 of the installation passageway 240, so that the first communication port 243 and the second communication port 244 are disconnected from each other. In other embodiments, when the movable member 300 moves to the closed position, the first sealing portion 310 may also block the second communication port 244, so that the first communication port 243 and the second communication port 244 are disconnected; or in other embodiments, when the movable member 300 moves to the closed position, the first sealing portion 310 moves between the first communication port 243 and the second communication port 244, so that the first communication port 243 and the second communication port 244 are disconnected.

In some embodiments, as shown in fig. 2 to 6, the movable member 300 further includes a second sealing portion 320 and a third sealing portion 330 which are in sealing connection with the inner wall of the installation passageway 240, and the second sealing portion 320, the second communication port 244 and the third sealing portion 330 are sequentially disposed along the first direction 600, that is, the second sealing portion 320 and the third sealing portion 330 are located at both sides of the second communication port 244, which plays a role in sealing water leakage. In the embodiment shown in fig. 6, the second sealing part 320 is provided at the upper end of the movable member 300, enabling a sealed connection of the movable member 300 and the first mounting channel 241 to prevent water from oozing out from the button 130. The third sealing part 330 is provided at the lower end of the movable member 300, and enables a sealing connection of the movable member 300 and the second installation passageway 242 to prevent water from leaking out of the air pressure balance hole 246 of the second receiving chamber 245. The second sealing part 320 includes a first sealing ring 321, and the third sealing part 330 includes a second sealing ring 331. In the embodiment shown in fig. 4 to 6, the first seal ring 321 and the second seal ring 331 are both Y-shaped seal rings, the outer diameter of the first seal ring 321 gradually increases along the first direction 600, and the outer diameter of the second seal ring 331 gradually decreases along the first direction 600. When the external water valve is opened, the channel between the second sealing part 320 and the third sealing part 330 is filled with water, the edge wings of the Y-shaped sealing ring are opened under the action of water pressure, and the contact area with the inner wall of the installation channel 240 is increased, 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 edge wing of the Y-shaped sealing ring is restored to be smaller in contact area with the inner wall of the installation channel 240, so that the moving of the movable piece 300 is facilitated.

In some embodiments, as shown in fig. 2-6, to reduce the difficulty of manufacturing the shunt member 200, the shunt member 200 is manufactured separately. The flow dividing member 200 includes a first body member 210 and a second body member 220, and the first body member 210 and the second body member 220 are respectively in sealing connection with the inner wall of the first receiving chamber. The first body member 210 and the second body member 220 are spaced apart and define a water gap 250 therebetween that communicates with the water inlet 110. The mounting channel 240 includes a first mounting channel 241 defined by the first body member 210 and a second mounting channel 242 defined by the second body member 220. The three mounting channels 240 include three first mounting channels 241 and second mounting channels 242, the first mounting channels 241 and the second mounting channels 242 are spaced apart, and at the space therebetween, the first mounting channels 241 and the second mounting channels 242 are respectively communicated with the water passing gap 250, wherein the first mounting channels 241 are communicated with the water outlet channel 230 through the first communication ports 243. The movable member 300 includes a first sealing portion 310, and the first sealing portion 310 is located in the water gap 250 and is capable of moving to block the first installation channel 241 so that water cannot flow out of the first installation channel 241 and the corresponding water outlet channel 230.
