Technical Field

[0001] The present application relates to the technical field of water supply equipment, and in particular to a water diversion valve and shower equipment. Background Art

[0002] In the related technology, the water outlet device realizes the opening and closing of the water circuit through the main valve core, the water diverter valve switches the opening and closing of different water outlet channels, the water circuit is switched by operating different water diverter buttons, and the water inlet water circuit of the water diverter valve is shut off by operating another main valve core by the driving component. One of the water outlet channels of the water diverter valve remains open. When the driving component operates the main valve core to open it again, water flows out through the water outlet channel of the water diverter valve that remains open, which may cause the unexpected water circuit to be opened, causing the user to be accidentally showered, affecting the user experience. Utility Model Content

[0003] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application proposes a water diverter valve capable of preventing accidental showering. The present application also proposes a shower device having the water diverter valve.

[0004] In a first aspect, a water diversion valve according to an embodiment of the present application includes a valve body assembly, at least two water diversion assemblies, a switching assembly, and a switch assembly;

[0005] The valve body assembly is provided with a water inlet channel communicating with the outside of the valve body assembly, and at least two water outlet channels communicating with the water inlet channel and the outside of the valve body assembly;

[0006] The water-dividing assembly corresponds to the water outlet channel one by one, and at least a part of the water-dividing assembly is located inside the valve body assembly; the water-dividing assembly is configured to be driven in the up-down direction and can switch between a blocking state and a conducting state, in which the water-dividing assembly blocks the corresponding water outlet channel in the blocking state, and conducts the corresponding water outlet channel in the conducting state;

[0007] The switching component is movably disposed inside the valve body component, and is used to lock one of the water-dividing components in the conducting state. The switching component is configured to drive the switching component to move when any water-dividing component switches from the blocking state to the conducting state, so as to unlock the previously locked water-dividing component;

[0008] The switch assembly is located between at least two water-dividing assemblies, and the switch assembly includes a switch drive assembly and a switch valve core. The switch drive assembly is connected to the valve body assembly, and at least a portion of the switch valve core is arranged in the valve body assembly and corresponds to the water inlet channel. The switch valve core is driven to move in the up and down directions to switch the on and off of the water inlet channel; the switch drive assembly and / or a set water-dividing assembly is connected to a switch connecting rod support arm. When the switch drive assembly is driven to drive the switch valve core downward to block the water inlet channel, the set water-dividing assembly is driven downward by the switch connecting rod support arm to switch from a blocking state to a conducting state.

[0009] The water distribution valve according to the embodiments of the present application has at least the following beneficial effects:

[0010] The switching of different water outlet channels is realized through the water distribution component and the switching component. Moreover, the on-off switching of the water inlet channel is realized through the switch valve core in the switch component. Therefore, when it is necessary to stop the water outlet, the switch valve core can be driven by the switch driving component to block the water inlet channel to realize the water closing function. At the same time, the switch driving component drives a set water distribution component through the switch link arm to keep the corresponding water outlet channel conducting. Thus, it is realized that a certain water outlet channel is kept conducting by default after each water closing, ensuring that when using next time, the water preferentially flows out from the water outlet channel corresponding to the set water distribution component, and avoiding water spraying by mistake from other water outlet channels. For example, in some applications, the water distribution valve can be used in shower equipment. The lower water outlet part of the shower equipment can be connected to the water outlet channel corresponding to the set water distribution component, and the remaining water outlet parts such as the overhead shower can be respectively connected to other water outlet channels. Thus, the water outlet water path of the lower water outlet part is conducted by default after each water closing. When using next time, the water preferentially flows out from the lower water outlet part, rather than from other water outlet parts such as the overhead shower, thereby avoiding water spraying by mistake.

[0011] For the water distribution valve according to some embodiments of the present application, the switch driving component includes a fixing part, a movable part and a switch reset part.

[0012] The movable part and / or a set water distribution component are / is connected with a switch link arm;

[0013] The movable part can be driven to move downward to push the switch valve core to block the water inlet channel, and abut against the set water distribution component through the switch link arm to make it in a conducting state. The switch reset part is used to drive the movable part to reset in the reverse direction.

[0014] For the water distribution valve according to some embodiments of the present application, the movable part includes a switch button, a switching core shaft and a rotating shaft connected in sequence.

The switch button can be driven downward to drive the switching core shaft to move and push against the rotating shaft. The rotating shaft is configured to be suitable for rotating relative to the fixing part along with the pushing of the switching core shaft. A locking structure for locking the relative positions of the rotating shaft and the fixing part is provided between the rotating shaft and the fixing part.

The switching elastic member is used to drive the switching drive rod to move away from the switching valve port, and the switching diaphragm is adapted to open the switching valve port under the action of water pressure.

[0016] According to some embodiments of the present application, for the water distribution valve, the water distribution components are circumferentially distributed around the switching component.

The dial is used to lock one of the water distribution components in the conducting state. When any of the remaining water distribution components is switched from the blocking state to the conducting state, it can drive the dial to rotate to release the lock on the previously locked water distribution component, and the dial reset member is used to drive the dial to rotate in the reverse direction to reset and lock the currently conducting water distribution component.

[0018] According to some embodiments of the present application, for the water distribution valve, the water distribution component includes a water distribution drive rod and a water distribution link arm. The water distribution drive rod is movably connected to the valve body assembly in the up and down direction, and the water distribution link arm is connected to the water distribution drive rod and protrudes relative to the outer wall of the water distribution drive rod.

[0020] When one of the water distribution components is switched from the blocking state to the conducting state, the corresponding water distribution drive rod drives the water distribution link arm to move along the driving inclined surface into the avoidance groove, and drives the dial to rotate until the previously carded water distribution link arm by the card slot disengages from the card slot. The dial is driven by the dial reset member to rotate in the reverse direction so that the currently water distribution link arm in the avoidance groove is snapped into the card slot, locking the corresponding water distribution component in the conducting state.

[0059] The embodiments of the present application provide a water distribution valve, which is used to switch and conduct at least two water outlet channels. It not only has a water closing function, but also keeps the set water outlet channel conducting after each water closing, so that water flows out from the set water outlet channel preferentially when used again.

[0060] The following introduces the embodiments of the present application in conjunction with the accompanying drawings of the specification:

[0061] Reference Figures 1 to 4 , the water distribution valve of the embodiments of the present application includes a valve body assembly 100, a water distribution assembly 200, a switching assembly 300, and a switch assembly 400.

[0062] The valve body assembly 100 is provided with an inlet channel 101 communicating with the outside of the valve body assembly 100, and at least two outlet channels 102 communicating the inlet channel 101 and the outside of the valve body assembly 100.

[0063] The number of the water distribution components 200 is the same as that of the water outlet channels 102. The water distribution components 200 and the water outlet channels 102 are in one-to-one correspondence. The water distribution components 200 are used to switch the on-off of the corresponding water outlet channels 102. The water distribution components 200 cooperate with the switching component 300 to keep one of the water distribution components 200 conducting the corresponding water outlet channel 102, and when any other water distribution component 200 is driven to conduct the corresponding water outlet channel, the water distribution component 200 that previously conducted the corresponding water outlet channel 102 is switched to block the corresponding water outlet channel 102, so as to realize the switching and conduction of different water outlet channels 102.

[0064] Wherein, at least a part of the water distribution component 200 is located inside the valve body component 100, and the water distribution component 200 is configured to be driven in the up-and-down direction to be able to switch between a blocking state and a conducting state. The up-and-down direction is referenced to the up-and-down direction shown in the drawings, and is not limited to the vertical up-and-down direction in actual applications. In actual applications, with the different placement directions of the water distribution valve, the up-and-down direction of the water distribution valve can be along the horizontal direction, the vertical direction or a direction with a certain inclination angle relative to the vertical direction. In the blocking state, the water distribution component 200 blocks the corresponding water outlet channel 102, and the water distribution component 200 can be driven downward to switch to the conducting state. In the conducting state, the water distribution component 200 conducts the corresponding water outlet channel 102, and the water distribution component 200 can be driven upward to switch to the blocking state. The switching component 300 is movably arranged inside the valve body component 100, and the switching component 300 is used to lock one of the water distribution components 200 in the conducting state to ensure that the corresponding water outlet channel 102 remains stably conducting. When any water distribution component 200 switches from the blocking state to the conducting state, it can drive the switching component 300 to move to release the locking of the previously locked water distribution component 200, so as to realize the switching and conduction of different water outlet channels 102.

[0065] The switch component 400 is located between at least two water distribution components 200. The switch component 400 includes a switch driving component 410 and a switch valve core 420. The switch driving component 410 is connected to the valve body component 100. At least a part of the switch valve core 420 is arranged inside the valve body component 100 and corresponds to the water inlet channel 101. The switch valve core 420 can be driven to move in the up-and-down direction to switch the on-off of the water inlet channel 101. Therefore, when it is necessary to stop the water outlet, the switch driving component 410 can be used to drive the switch valve core 420 to move to block the water inlet channel 101 to realize the water closing function. When water outlet is needed, the switch valve core 420 can be driven to move by the driving component or the switch valve core 420 can be driven to return by other driving structures such as a reset member, so as to conduct the water inlet channel 101 to realize water inlet.

[0066] Reference Figures 4 to 6, wherein, a switch link arm 220 is connected to the switch driving assembly 410 and / or a set of water distribution assemblies 200. When the switch driving assembly 410 is driven downward to drive the switch valve core 420 to block the water inlet channel 101, the set of water distribution assemblies 200 is driven downward through the switch link arm 220 to switch from the blocked state to the conducting state. Therefore, while the switch driving assembly 410 drives the switch valve core 420 to close the water inlet channel 101 to achieve the water shut-off function, the switch driving assembly 410 drives the set of water distribution assemblies 200 through the switch link arm 220 to keep the corresponding water outlet channel 102 conducting.

[0067] When the water distribution valve of the embodiment of the present application is in use, refer to Figure 4 , in the initial position, the water distribution assembly 200 keeps blocking the corresponding water outlet channel 102, and the switch assembly 400 keeps the water inlet channel 101 conducting. Refer to Figure 5 、 Figure 6 , drive the switch driving assembly 410 downward to push the switch valve core 420 to block the water inlet channel 101. At the same time, the switch driving assembly 410 drives the set of water distribution assemblies 200 downward to conduct the corresponding water outlet channel 102. At this time, the water distribution valve is in the first state, that is, the water shut-off state, the water inlet channel 101 is closed and the set water outlet channel 102 is conducting.

[0068] Refer to Figures 6 to 8 , in the first state, control the switch valve core 420 through the switch driving assembly 410 to open the water inlet channel 101 and conduct it with the set water outlet channel 102. At this time, the water distribution valve is in the second state, that is, the water outlet state, and the water can flow out through the water inlet channel 101 and the set water outlet channel 102. In the second state, different water distribution assemblies 200 can be driven to switch to conduct the corresponding water outlet channels 102. By driving the switch valve core 420 through the switch driving assembly 410 to block the water inlet channel 101, the water can be shut off, and the water distribution valve returns to the first state, and the set water outlet channel 102 remains conducting. Thus, when switching to the second state to conduct the water inlet channel 101 next time, it can be ensured that the water flows out from the set water outlet channel 102.

[0069] During operation, both water outlet and water shut-off can be operated by pressing the switch driving assembly 410. The operation is simple and convenient. After each water shut-off, a certain water outlet channel 102 is default to be conducting, ensuring that when using next time, the water flows out from the water outlet channel 102 corresponding to the set water distribution assembly 200 preferentially, avoiding water splashing from other water outlet channels 102. Therefore, when using, there is no need to confirm whether the currently conducting water outlet channel 102 will splash water, which is beneficial to improving the use experience.

[0070] In some applications of the embodiments of the present application, the water diverter valve can be used in a shower device having a lower water outlet member and an overhead shower. The lower water outlet member and the overhead shower are respectively connected to different water outlet channels 102. The lower water outlet member can be connected to the water outlet channel 102 corresponding to the set water diverter assembly 200 described above, and the remaining water outlet members such as the overhead shower can be respectively connected to other water outlet channels 102. By switching the conduction of the water outlet channel 102, the water outlet of the lower water outlet member or the overhead shower can be switched. After the water is turned off, the water outlet waterway of the lower water outlet member is defaultly conducted. When used next time, the water will first flow out from the lower water outlet member instead of flowing out from other water outlet members such as the overhead shower, resulting in accidental spraying.

[0071] Reference Figure 3 、 Figure 4 , in some embodiments, the switch driving assembly 410 includes a fixing member 411 and a movable member. The fixing member 411 is connected to the valve body assembly 100 to realize the installation of the switch driving assembly 410.

[0072] The movable member is movably connected to the fixing member 411 and abuts against the switch valve core 420. The movable member and / or a set water diverter assembly 200 are connected with a switch link support arm 220. The switch link support arm 220 is used to link the movable member and the set water diverter assembly 200. While the movable member is driven downward to push the switch valve core 420 to block the water inlet channel 101, the movable member abuts against the set water diverter assembly 200 through the switch link support arm 220 and pushes the water diverter assembly 200 to move to the conducting state, so that the corresponding water outlet channel 102 is conducted.

[0073] The switch driving assembly 410 may further include a switch reset member 415. The switch reset member 415 is located between the movable member and the fixing member 411 and is used to drive the movable member to reset in the reverse direction. For example, when the movable member is in the initial position, the switch valve core 420 conducts the water inlet channel 101. The movable member is driven downward to push the switch valve core 420 to move, and at the same time drives the set water diverter assembly 200 downward, so as to close the water inlet channel 101 and conduct the set water outlet channel 102. The switch reset member 415 is used to drive the movable member to move upward and reset to the initial position.

[0074] The movable part may include a switch button 412, a switching mandrel 413, and a rotating shaft 414 that are connected in sequence. The rotating shaft 414 is rotatably sleeved with the fixed part 411. The rotating shaft 414 is configured to rotate relative to the fixed part 411 when pushed by the switching mandrel 413. The rotating shaft 414 abuts against the switch valve core 420. A locking structure for locking the relative positions of the rotating shaft 414 and the fixed part 411 is provided between the rotating shaft 414 and the fixed part 411. When the switch button 412 is driven downward, it can drive the switching mandrel 413 to move and push the rotating shaft 414. During the process of the switching mandrel 413 pushing the rotating shaft 414 to move, the rotating shaft 414 is driven to rotate. The rotating shaft 414 pushes the switch valve core 420 to move to block the water inlet channel 101, and the locking structure between the rotating shaft 414 and the fixed part 411 locks the rotating shaft 414. The rotating shaft 414 is adapted to switch the locking state and the unlocking state of the locking structure by rotation. Driving the switching mandrel 413 to push the rotating shaft 414 to move and rotate again can switch to the unlocking state.

[0075] Reference Figures 4 to 6 , a switch reset member 415 is provided between the switch button 412 and the fixed part 411. In the initial state, the switch button 412 is located at the first button position D1 (Reference Figure 4 ). When the switch button 412 is pressed downward, it can move to the second button position D2 (Reference Figure 5 ) by overcoming the elastic force of the switch reset member 415. At this time, the water inlet channel 101 is closed. After releasing the pressing force on the switch button 412, the switch reset member 415 drives the switch button 412 to reset upward to the first button position D1 (Reference Figure 6 ) through the elastic force.

[0076] Reference Figure 3 、 Figure 4 , the switch valve core 420 may include a switch driving rod 421 and a switch elastic member 422. The switch driving rod 421 abuts against the rotating shaft 414. The switch elastic member 422 provides an elastic force that drives the switch driving rod 421 to move in the direction towards the rotating shaft 414. When the locking structure is in the unlocked state, the switch reset member 415 drives the switch button 412 to move and reset in the direction away from the switch valve core 420 (i.e., upward). The switch elastic member 422 can drive the switch driving rod 421 to move in the direction towards the rotating shaft 414 through the elastic force to conduct the water inlet channel 101. At the same time, the switch driving rod 421 can push the rotating shaft 414 to move in the direction towards the switch button 412, driving the switch driving member and the rotating shaft 414 to reset.

[0077] Reference Figure 3 、 Figure 4, the switch valve core 420 may also include a switch diaphragm 423 and a support 424, the support 424 is located inside the valve body assembly 100 and connected to the valve body assembly 100, the water inlet channel 101 has a switch valve port 133, the edge of the switch diaphragm 423 is fixed between the valve body assembly 100 and the support 424, and the abutment 4231 of the switch diaphragm 423 is located above the switch valve port 133, which is used to switch the switch valve port 133 open and closed. In the initial state, the abutment 4231 of the switch diaphragm 423 is in the first switch diaphragm position B1, there is a gap between the abutment 4231 and the switch valve port 133, and the switch valve port 133 is conductive. The switch driving rod 421 is driven by the switch driving assembly 410 to push the abutment 4231 of the switch diaphragm 423 to block the switch valve port 133 to block the water inlet channel 101, and at this time, the abutment 4231 is in the second switch diaphragm position B2. The switch elastic member 422 is used to drive the switch driving rod 421 to move in a direction away from the switch valve port 133 to reset, and the abutment portion 4231 of the switch diaphragm 423 is suitable for deforming under the action of water pressure to open the switch valve port 133, and the abutment portion 4231 can return to the first switch diaphragm position B1. At this time, the reset of the switch driving rod 421 is not affected by the water pressure, and the reset is more reliable, effectively ensuring that the water inlet channel 101 is smoothly opened to let water in.

[0078] refer to Figures 8 to 10 As an example, the following configuration may be adopted so that the rotating shaft 414 can switch the locking state and the unlocking state of the locking structure by rotation: the fixing member 411 may be provided with an inner cavity, one end of the switching spindle 413 is located in the inner cavity, and the other end is connected to the switch button 412, the switch reset member 415 is located between the switch button 412 and the fixing member 411, at least a part of the rotating shaft 414 is located in the inner cavity and is rotatably sleeved with the switching spindle 413, the end (i.e., the lower end) of the switching spindle 413 facing away from the switch button 412 is provided with a tooth surface 4131, and the rotating shaft 414 is provided with a tooth surface 4131. There is a limiting protrusion 4141 corresponding to the tooth surface 4131, the limiting protrusion 4141 is convexly arranged on the outer peripheral surface of the rotating shaft 414, and the limiting protrusion 4141 forms a guiding inclined surface 4142 at one end facing the switching core shaft 413. The inner wall of the fixing member 411 is provided with a limiting groove 4113 extending in the up-down direction, and the inner wall of the fixing member 411 is also provided with a step ratchet 4112. The limiting groove 4113 runs through the side of the step ratchet 4112 away from the switching core shaft 413, and the limiting protrusion 4141 is located in the limiting groove 4113 and can move along the limiting groove 4113. The limiting protrusion 4141, the limiting groove 4113 and the step ratchet 4112 constitute a locking structure. The tooth surface 4131 abuts against the guiding inclined surface 4142 of the limiting protrusion 4141, which can drive the rotating shaft 414 to rotate while pushing the rotating shaft 414 to move.

[0079] The switch button 412 is driven to move between the first button position D1 and the second button position D2 in the up-down direction, and the switch reset member 415 is used to drive the switch button 412 to reset to the first position in the direction away from the fixing member 411 (i.e., upward). In the process of driving the switch button 412 downward from the first button position D1 to the second button position D2, the switch button 412 pushes the switching valve core to abut against the rotating shaft 414 to move downward, and the limiting protrusion 4141 moves along the limiting groove 4113 to be separated from the limiting groove 4113. At the same time, the switching valve core abuts against the guiding inclined surface 4142 of the limiting protrusion 4141 through the tooth surface 4131 to rotate the rotating shaft 414, so that the limiting protrusion 4141 and the step ratchet 4112 are engaged and locked, and the limiting protrusion 4141 and the step ratchet 4112 cooperate to limit the relative position of the rotating shaft 414 and the fixing member 411, and the switch valve core 420 blocks the water inlet channel 101. At this time, the driving force of the switch button 412 is released, and the switch reset member 415 can drive the switch button 412 to reset upward to the first button position D1. The rotating shaft 414 is locked by the locking mechanism and does not reset with the switch button 412, thereby maintaining contact with the switch valve core 420, and the water inlet channel 101 remains blocked.

[0080] The switch button 412 is driven downward again to push the switch core shaft 413 to abut the rotating shaft 414, which can push the rotating shaft 414 away from the stepping ratchet 4112, and at the same time, the tooth surface 4131 pushes the guide inclined surface 4142 to rotate the rotating shaft 414, so that the limiting protrusion 4141 enters the limiting groove 4113 to achieve unlocking. In the unlocked state, the switch reset member 415 drives the switch button 412 upward to move and reset, and the switch elastic member 422 can drive the switch driving rod 421 to move upward through elastic force to conduct the water inlet channel 101. At the same time, the switch driving rod 421 can push the rotating shaft 414 to move upward, and the limiting protrusion 4141 moves toward each other along the limiting groove 4113, so that the switch driving member and the rotating shaft 414 are reset.

[0081] In some related technologies, a main valve core is set at the position where the mixing channel of the shower equipment is connected to the cold water inlet channel and the hot water inlet channel, so as to control the on-off of the water inlet waterway entering the water diversion valve before the water enters the water diversion valve, and the main valve core is connected to a designated water diversion button through a connecting piece. While the main valve core is operated by the driving part to shut off the water inlet waterway of the water diversion valve, the driving part can drive the connecting piece to drive the designated water diversion button to move to open the corresponding channel, and at the same time switch other water diversion buttons to close the corresponding channels. Therefore, when the main valve core opens the waterway again, the designated waterway is turned on by default, thereby avoiding the problem of accidental showering caused by the conduction of other waterways. However, the main valve core controls the on-off of the water inlet waterway outside the water diversion valve, and the on-off response of the water outlet of the water diversion valve is slow, and the connecting piece occupies a large volume. The connection structure of the driving part, the connecting piece and the water diversion button is relatively complicated, resulting in cumbersome assembly.

[0082] A switch assembly 400 is provided on the water diversion valve according to the embodiments of the present application to control the on-off of the water inlet channel 101 inside the valve body 110, which can improve the response speed of water outlet and water cut-off. Moreover, the switch assembly 400 and the set water diversion assembly 200 can be interlocked only through the switch link arm 220, realizing the conduction of the set water outlet channel 102 while cutting off the water. The interlocking structure is simple and easy to implement, and the overall structure is more compact.

[0083] In some embodiments, referring to Figures 1 to 4 , the water diversion assemblies 200 are circumferentially distributed around the switch assembly 400, that is, the switch assembly 400 is located in the middle of the circumference where the water diversion assemblies 200 are distributed. Compared with the scheme where the water diversion assembly 200 and the switch assembly 400 are linearly distributed, the distribution length is reduced. Compared with the scheme where the switch assembly 400 and the water diversion assembly 200 are annularly distributed, the space surrounded by the water diversion assemblies 200 is effectively utilized. Therefore, the overall structure is more compact.

[0084] Among them, the switch driving assembly 410 includes a switch button 412, and the water diversion assembly 200 includes a water diversion button 210. The water diversion buttons 210 are circumferentially distributed around the switch button 412. The water diversion button 210 of a set water diversion assembly 200 is connected with a switch link arm 220. The switch link arm 220 extends from the side wall of the water diversion button 210 in the direction of the switch button 412 to one end located below the switch button 412 of the switch driving assembly 410. Therefore, pressing the button downward can simultaneously push the switch link arm 220 to drive the set water diversion assembly 200 to conduct the corresponding water outlet channel 102, and the switch link arm 220 does not need to be assembled and connected with the switch driving assembly 410. The switch link arm 220 can be integrally formed with the set switch button, further simplifying the assembly.

[0085] In some embodiments, the water diversion button 210 can be arranged in a removable manner. Therefore, by replacing the water diversion button 210 of the water diversion assembly 200 and changing the button connected with the switch link arm 220 to the required water diversion assembly 200, the water outlet channel 102 that is defaultly conducted after water cut-off can be customized, improving the flexibility of the valve core assembly.

[0086] In some embodiments, the water distribution components 200 are circumferentially distributed around the switch component 400. The switching component 300 includes a dial 310 and a dial 310 return member. The dial 310 is rotatably disposed within the valve body component 100, and the dial 310 return member is disposed between the dial 310 and the valve body component 100. The dial 310 is used to lock one of the water distribution components 200 in the conducting state to ensure stable water output. When any other water distribution component 200 switches from the blocking state to the conducting state, it can drive the dial 310 to rotate to release the locking of the previously locked water distribution component 200. The dial 310 return member is used to drive the dial 310 to rotate in the reverse direction to reset and lock the currently conducting water distribution component 200, realizing the linkage switching between any two water distribution components 200. The rotation of the dial 310 always rotates in the circumferential direction, without the need to make movement space for the rotation of the dial 310 in the radial or axial directions. While ensuring a compact structure, the linkage between any two water distribution components 200 is realized.

[0087] Reference Figures 11 to 12 , the water distribution component 200 may include a water distribution driving rod 230 and a water distribution link arm 240. The water distribution driving rod 230 is movably connected to the valve body component 100 in the up and down direction. The water distribution link arm 240 is connected to the water distribution driving rod 230 and protrudes relative to the outer wall of the water distribution driving rod 230. The water distribution link arm 240 can be connected to the water distribution driving rod 230 by a fixed connection method, or can be integrally formed on the water distribution driving rod 230. The dial 310 surrounds the outside of all the water distribution driving rods 230. Avoidance grooves 311 and slots 312 communicating with the avoidance grooves 311 are provided at positions corresponding to the respective water distribution link arms 240 on the dial 310. The avoidance grooves 311 conduct the upper side edge of the dial 310 to enable the water distribution link arm 240 to enter and exit. Among them, the slot 312 communicates with one side wall of the avoidance groove 311 along the circumferential direction of the dial 310. The slot 312 is used to snap and lock the water distribution link arm 240 of the water distribution component 200 in the conducting state. After the water distribution link arm 240 enters the avoidance groove 311, the dial 310 can be rotated to move the slot 312 towards the water distribution link arm 240 until it accommodates it. The upper side wall of the slot 312 is used to abut against the upper side of the water distribution link arm 240, thereby locking the water distribution link arm 240.

[0088] A driving inclined surface 313 is provided on the groove wall of the avoidance groove 311. The driving inclined surface 313 extends obliquely upward. The driving inclined surface 313 abuts against the water distribution link arm 240, so that the water distribution link arm 240 can push the dial 310 to rotate along the driving inclined surface 313 when moving downward.

[0089] The water distribution drive rods 230 are circumferentially distributed around the fixing member 411. The water distribution link arms 240 are respectively convexly arranged in the direction of increasing radius of the dial 310. The avoidance grooves 311 on the dial 310 are arranged in one-to-one correspondence with the water distribution link arms 240. Thus, the movement of any one of the water distribution drive rods 230 can overcome the elastic force of the reset member of the dial 310 to drive the dial 310 to rotate, so that the water distribution link arm 240 enters the avoidance groove 311. Since the card slot 312 communicates with one side wall of the avoidance groove 311 along the circumferential direction of the dial 310, the elastic force of the reset member of the dial 310 causes the dial 310 to rotate in the reverse direction to make the water distribution link arm 240 enter the card slot 312 to achieve locking.

[0090] During application, when one of the water distribution assemblies 200 is switched from the blocking state to the conducting state, the corresponding water distribution drive rod 230 drives the water distribution link arm 240 to move downward. The water distribution link arm 240 moves along the driving inclined surface 313 and enters the avoidance groove 311, and drives the dial 310 to rotate so that the water distribution link arm 240 that was previously clamped by the card slot 312 disengages from the card slot 312. The dial 310 rotates in the reverse direction under the drive of the reset member of the dial 310 so that the water distribution link arm 240 currently in the avoidance groove 311 is clamped into the card slot 312, locking the corresponding water distribution assembly 200 in the conducting state.

[0091] In some embodiments, referring to Figures 4 to 6 , the water distribution assembly 200 further includes a water distribution diaphragm 250. The water distribution diaphragm 250 includes a main body portion 251 and an edge portion 252 surrounding the main body portion 251. The edge portion 252 is connected to the valve body assembly 100. The main body portion 251 is provided with a through hole 253. The water distribution drive rod 230 includes a rod portion 231 and a recessed portion 232. The rod portion 231 can block the through hole 253. The recessed portion 232 is recessed radially with respect to the outer peripheral surface of the rod portion 231. When the water distribution drive rod 230 moves to the position where the recessed portion 232 is located within the through hole 253, there is a clearance between the hole wall of the through hole 253 and the recessed portion 232, so that the main body portion 251 can move freely. The main body portion 251 can be deformed under the drive of water pressure or elastic force to change the on-off state of the water outlet channel 102.

[0092] Specifically, an outlet valve port 142 is provided in the water outlet channel 102. In the initial state, the main body portion 251 of the water distribution diaphragm 250 is in the first water distribution diaphragm position C1. The rod portion 231 of the water distribution driving rod 230 blocks the through hole 253, and the outer wall of the rod portion 231 fits against the hole wall of the through hole 253 to prevent the main body portion 251 from moving freely. The main body portion 251 blocks the outlet valve port 142 to block the water outlet channel 102, and the main body portion 251 has elastic deformation. The water distribution driving rod 230 can be driven to move relative to the main body portion 251 until the recessed portion 232 is located in the through hole 253. There is a clearance space between the hole wall of the through hole 253 and the recessed portion 232, so that the main body portion 251 can move freely. The main body portion 251 is elastically deformed to open the outlet valve port 142 to conduct the corresponding water outlet channel 102. The main body portion 251 is in the second water distribution diaphragm position C2, and the water distribution connecting rod arm 240 is engaged with the corresponding card slot 312 on the dial 310.

[0093] The water distribution assembly 200 further includes a switching elastic member 260. When the water distribution connecting rod arm 240 disengages from the card slot 312, the switching elastic member 260 drives the water distribution connecting rod arm 240 to withdraw from the avoidance groove 311, and drives the water distribution driving rod 230 to move so that the rod portion 231 blocks the through hole 253. The main body portion 251 deforms toward the outlet valve port 142 under the action of water pressure and elastic force and blocks the outlet valve port 142 to block the corresponding water outlet channel 102. The downward movement or reset of the water distribution driving rod 230 is not affected by water pressure, and the requirements for pipeline back pressure and the water pressure of the user's home are low; the movement is more reliable.

[0094] Reference Figures 13 to 15 , in some embodiments, the valve body assembly 100 includes a valve body 110 and an inlet bracket 120. The inlet bracket 120 is located inside the valve body 110. An inlet cavity 121 is provided on the inlet bracket 120. The valve body 110 is provided with an inlet port 111 communicating with the inlet cavity 121. The inlet port 111 and the inlet cavity 121 define an inlet channel 101. The inlet bracket 120 is further provided with a first installation cavity 122 and at least two second installation cavities 123. The first installation cavity 122 communicates with the inlet cavity 121. The switch valve core 420 is installed in the first installation cavity 122, and the edge of the switch diaphragm 423 abuts between the inlet bracket 120 and the support 424. The number of the second installation cavities 123 is equal to the number of the water distribution assemblies 200, and each water distribution assembly 200 is correspondingly installed in the second installation cavity 123.

[0095] There is an installation space between the inlet bracket 120 and the valve body 110. The dial 310 is rotatably provided in this installation space. The dial 310 reset member can be between the dial 310 and the inlet bracket 120. The dial 310 reset member can be a torsion spring, with one end connected to the dial 310 and the other end connected to the inlet bracket 120.

[0096] The valve body assembly 100 further includes a base 140 and a water distribution plate 130. The water distribution plate 130 is located below the water inlet bracket 120, and the base 140 is provided below the water distribution plate 130 and connected to the water distribution plate 130. A water passage chamber 131 is defined between the base 140 and the water distribution plate 130. Below the position corresponding to each water distribution component 200 on the base 140, there are water outlet holes 141 that communicate the water passage chamber 131 with the outside of the base 140, forming a water outlet passage 102. One end of the water outlet hole 141 is located in the water passage chamber 131 to form a water outlet valve port 142. Below the position directly corresponding to the switch diaphragm 423 on the water distribution plate 130, there is a through hole 132 that communicates the water inlet chamber 121 and the water passage chamber 131. One end of the through hole 132 is located in the water inlet chamber 121 to form a switch valve port 133. The water distribution diaphragm 250 closes the water outlet valve port 142 to block the corresponding water outlet passage 102, and opens the water outlet valve port 142 to conduct the corresponding water outlet passage 102 and the water passage chamber 131. The switch diaphragm 423 closes the switch valve port 133 to block the water inlet passage 101, and opens the switch valve port 133 to conduct the water inlet passage 101 and the water passage chamber 131. When the switch valve port 133 is opened, water enters the water passage chamber 131 from the water inlet passage 101 and then flows out from the conducted water outlet passage 102.

[0097] The shower device according to the embodiment of the present application includes the aforementioned water distribution valve, and water outlet members having the same number as the water outlet passages 102. Each water outlet member is correspondingly connected to one water outlet passage 102, and the water outlet passage 102 corresponding to the water distribution component 200 driven by the switch driving assembly 410 through the switch link arm 220 is communicated with a set water outlet member.

[0098] During application, a set water outlet member can be connected to the water outlet passage 102 corresponding to the set water distribution component 200, and the remaining water outlet members can be respectively connected to other water outlet passages 102. Thus, after each water shut-off, the water outlet water path of the set water outlet member is default-conducted. Next time when in use, water preferentially flows out from the set water outlet member instead of other water outlet members such as the overhead shower, realizing the certainty of water outlet and thus avoiding accidental spraying.

[0099] As an example, refer to Figure 1 and Figure 2, the water distribution valve includes four water distribution components 200, and the valve body component 100 is correspondingly provided with four water outlet channels 102. Each water outlet channel 102 is respectively used to connect four water outlet parts in the shower equipment: the lower water outlet part, the handheld shower head, the ceiling shower head, and the spray gun. The water distribution buttons 210 on the water distribution component 200 corresponding to the lower water outlet part, the handheld shower head, the ceiling shower head, and the spray gun can be sequentially recorded as the lower water outlet button 211, the handheld button 212, the ceiling spray button 213, and the spray gun button 214. Among them, the switch link support arm 220 is connected to the lower water outlet button 211, and the corresponding water distribution drive rods 230 can be sequentially recorded as the lower water distribution drive rod 230, the handheld water distribution drive rod 230, the ceiling spray water distribution drive rod 230, and the spray gun water distribution drive rod 230. The corresponding water outlet channels 102 can be sequentially recorded as the lower water outlet channel 102, the handheld water outlet channel 102, the ceiling spray water outlet channel 102, and the spray gun water outlet channel 102.

[0100] In the initial state of the water distribution valve, when the switch button 412 is pressed, the switch button 412 moves from the first button position D1 to the second button position D2. During the movement of the switch button 412, the rotating shaft 414 is driven to move along the step ratchet 4112 through the switching core shaft 413. The rotating shaft 414 drives the switch drive rod 421 to move downward until the rotating shaft 414 is locked by the ratchet tooth surface 4131. The switch drive rod 421 pushes the abutting portion 4231 of the switch diaphragm 423 to move from the first switch diaphragm position B1 to the second switch diaphragm position B2 to fit with the switch valve port 133, blocking the water inlet channel 101 and realizing the closing of the water circuit.

[0101] During the process of pressing the switch button 412, the switch button 412 contacts the switch link support arm 220 on the lower water outlet button 211. Under the action of the pressing force, the switch button 412 drives the lower water outlet button 211 to move downward through the switch link support arm 220, realizing the linkage between the switch button 412 and the lower water outlet button 211. Thus, the switch button 412 drives the lower water distribution drive rod 230 to move downward. When the water distribution link support arm 240 of the lower water distribution drive rod 230 enters the avoidance groove 311, the dial 310 is driven by the torsion spring to rotate clockwise, and the card slot 312 on the dial 310 is engaged with the water distribution link support arm 240 of the lower water distribution drive rod 230. After the lower water distribution drive rod 230 moves downward, the concave portion 232 of the lower water distribution drive rod 230 reaches the through hole 253 of the main body portion 251 of the water distribution diaphragm 250, leaving a clearance with the main body portion 251 of the water distribution diaphragm 250, causing the main body portion 251 to deform upward under the action of the plastic elastic force. The main body portion 251 of the water distribution diaphragm 250 moves from the first water distribution diaphragm position C1 to the second water distribution diaphragm position C2, opening the lower water outlet channel 102.

[0102] At this time, the water diversion valve is in the first state, that is, the water inlet channel 101 is closed and the lower water outlet channel 102 is open.

[0103] After the switch button 412 is released, under the action of the reset spring force of the switch reset member 415, the switch button 412 returns from the second button position D2 to the first button position D1.

[0104] When the switch button 412 is pressed again, the switch button 412 moves from the first button position D1 to the second button position D2. During the movement of the switch button 412, the switching mandrel 413 is driven to drive the rotating shaft 414 to move along the stepping ratchet 4112. After the rotating shaft 414 crosses the ratchet inclined tooth surface 4131, it is unlocked. Under the action of the spring force of the switch elastic member 422, the switch driving rod 421 and the rotating shaft 414 move upward until the switch driving rod 421 is separated from the switch diaphragm 423. After the switch driving rod 421 is separated from the switch diaphragm 423, the switch diaphragm 423 has sufficient plastic elastic deformation space. Under the action of the plastic elastic force and water pressure, the switch diaphragm 423 moves from the second switch diaphragm position B2 to the first switch diaphragm position B1, separates from the water inlet valve port, opens the water inlet channel 101, and the water flow defaults to flow through the lower water outlet channel 102.

[0105] At this time, the water diversion valve is in the second state, that is, the water inlet channel 101 and the lower water outlet channel 102 are open. In the second state, the corresponding water outlet channel 102 can be switched on by pressing other water diversion buttons 210. For example:

[0106] When the handheld button 212 is pressed, the handheld button 212 and the handheld water diversion drive rod 230 move downward. During the movement, the water diversion link arm 240 on the handheld water diversion drive rod 230 contacts the drive inclined surface 313 of the dial 310, driving the dial 310 to rotate counterclockwise. After the dial 310 rotates counterclockwise, the card slot 312 of the dial 310 is separated and unlocked from the lower water outlet water diversion drive rod 230. The lower water outlet water diversion drive rod 230 is located in the avoidance slot 311 and moves upward above the drive inclined surface 313 of the dial 310 under the action of the spring force of the corresponding switching elastic member 260. After the lower water outlet water diversion drive rod 230 moves upward, the through hole 253 of the main body portion 251 of the corresponding water diversion diaphragm 250 is filled with the periphery of the rod portion 231 of the lower water outlet water diversion drive rod 230. The main body portion 251 of the water diversion diaphragm 250 deforms downward under the action of plastic elastic force and water pressure, and the main body portion 251 moves from the second water diversion diaphragm position C2 to the first water diversion diaphragm position C1, closing the lower water outlet channel 102. During the downward movement of the handheld water outlet drive rod, the water diversion link arm 240 on the handheld water outlet drive rod contacts the drive inclined surface 313 of the dial 310, driving the dial 310 to rotate counterclockwise. When the water diversion link arm 240 on the handheld water outlet drive rod moves to the corresponding card slot 312 of the dial 310, the dial 310 rotates clockwise under the action of the torsion spring force. The card slot 312 and the water diversion link arm 240 on the handheld water outlet drive rod are engaged and locked with each other. After the handheld water outlet drive rod moves downward, the recessed portion 232 of the handheld water outlet drive rod is cleared from the hole wall of the through hole 253 of the main body portion 251 of the water diversion diaphragm 250, causing the main body portion 251 to deform upward under the action of plastic elastic force. The main body portion 251 of the water diversion diaphragm 250 moves from the first water diversion diaphragm position C1 to the second water diversion diaphragm position C2, opening the handheld water outlet passage.

[0107] When the overhead shower button 213 is pressed, the overhead shower button 213 and the overhead shower water distribution drive rod 230 move downward. During the movement, the water distribution link arm 240 on the overhead shower water distribution drive rod 230 contacts the drive inclined surface 313 of the dial 310, driving the dial 310 to rotate counterclockwise. After the dial 310 rotates counterclockwise, the card slot 312 of the dial 310 is separated and unlocked from the hand-held water distribution drive rod 230.
