Description

[0001] Case information

[0002] This application is a divisional application of the application filed on November 23, 2023, with application number 2023115745957 and invention title "Water Control Valve and Water Discharge Device". Technical Field

[0003] This invention relates to the field of water valve technology, and in particular to a water control valve and a water outlet device. Background Technology

[0004] In related technologies, water outlet devices such as shower heads, shoulder sprays, waist sprays, and overhead sprays are equipped with water control valves to switch between different water outlet states. Taking a shower head with a water control valve as an example, the valve has multiple buttons. Pressing one button connects one water path, and the shower head is in the first water outlet state; pressing another button connects the other water path, and the shower head is in the second water outlet state. The previously pressed button pops up and closes the original water path. Traditional water control valves use a rotary dial to control the button opening and closing. To limit the position of the dial, various limiting structures are usually used to abut against the dial. Therefore, the frictional resistance of the dial during rotation is relatively large, resulting in uneven rotation, jamming, and strong damping. Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a water control valve that can improve problems such as uneven rotation of the turntable, jamming, and strong damping.

[0006] The present invention also proposes a water outlet device having the above-mentioned water control valve.

[0007] According to a first aspect of the present invention, a water control valve includes: a water distribution body having a water inlet and multiple water outlet channels.

[0008] Multiple sealing valve bodies, the same number as the water outlet channels, are used to block the corresponding water outlet channels;

[0009] The turntable is rotatable relative to the water distribution body. The turntable is provided with a plurality of first through holes, which are arranged around the rotation axis of the turntable. The turntable is provided with at least one positioning part at one end along the rotation axis, and the positioning part is provided with a reset inclined surface.

[0010] Multiple buttons are arranged around the rotation axis, and each of the multiple buttons is fixedly connected to a corresponding sealing valve body so that when the button is pressed, the corresponding water outlet channel is opened. A latch is provided on the side of the button away from the pressing surface of the button. The latch is configured to pass through the first through hole and engage with the turntable when the button is pressed.

[0011] At least one reset mechanism is provided on the water distribution body, the reset mechanism including a reset pin and an elastic element acting on the reset pin, the reset pin being configured to elastically abut against the reset inclined surface in a direction parallel to the rotation axis.

The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features or their sequential relationship.

[0060] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0061] Reference Figure 1 and Figure 2 As shown, a water control valve 1000 according to one embodiment of the present invention can be applied to water outlet devices such as shower heads, shoulder sprays, waist sprays, and overhead sprays. The water control valve 1000 is used to control the water outlet state of the water outlet device. The water control valve 1000 includes a water distribution body 100 and multiple buttons 400. The water distribution body 100 is provided with a water inlet 110 and multiple water outlet channels 120. The multiple buttons 400 control the opening and closing of the corresponding water outlet channels 120. For example, the water control valve 1000 is connected to a shower head. When one of the buttons 400 is pressed, the corresponding water outlet channel 120 is turned on, and the shower head is in the first water outlet state. When another button 400 is pressed, the original button 400 pops up and closes the corresponding water outlet channel 120, while the other water outlet channel 120 is turned on, so that the shower head is in the second water outlet state.

[0062] To improve the smoothness of switching between different button 400 settings, refer to Figure 3 As shown, in an embodiment of the present invention, the water control valve 1000 further includes multiple sealing valve bodies 200, a turntable 300, and at least one reset mechanism 500. The number of sealing valve bodies 200 is the same as the number of water outlet channels 120, for example, three in each case. The three sealing valve bodies 200 are used to block the corresponding water outlet channels 120. The turntable 300 is rotatable relative to the water distribution body 100. The turntable 300 is provided with multiple first through holes 310, which are arranged around the rotation axis of the turntable 300. (Refer to...) Figure 4 As shown, the turntable 300 has at least one positioning part 320 at one end along the rotation axis, and the positioning part 320 has a reset inclined surface 321. The positioning part 320 can be located at the upper or lower end of the turntable 300. Multiple buttons 400 are arranged around the rotation axis of the turntable 300, and each button 400 is fixedly connected to a corresponding sealing valve body 200 so that when the button 400 is pressed, the corresponding water outlet channel 120 is opened. The upper end of the button 400 has a pressing surface 410, and the side of the button 400 away from the pressing surface 410 has a latch 420. The latch 420 is configured to pass through the first through hole 310 and engage with the turntable 300 when the button 400 is pressed.

[0063] Reference Figure 3 As shown, a reset mechanism 500 is disposed on the water distribution body 100. The reset mechanism 500 includes a reset pin 510 and a first elastic element 520 acting on the reset pin 510. The first elastic element 520 can be a spring, elastic silicone, or rubber, etc. The reset pin 510 is configured to elastically abut against the reset inclined surface 321 in a direction parallel to the rotation axis of the turntable 300. Through the abutting cooperation between the reset pin 510 and the reset inclined surface 321, a reset force can be provided to the turntable 300, so that the turntable 300 is reset to its initial position.

[0064] Reference Figure 5 and Figure 6As shown, the water-sealing body includes a main body 140, which has multiple water passage holes 141. The number of water passage holes 141 is the same as the number of water outlet channels 120. The water inlet 110 is connected to the water outlet channel 120 through the corresponding water passage hole 141. The water-sealing valve body 200 is provided with a first sealing ring 230, which can seal with the water passage hole 141 to block the corresponding water outlet channel 120. When the button 400 is pressed, the water-sealing valve body 200 can be moved downward, causing the first sealing ring 230 to open the water passage hole 141, and the corresponding water outlet channel 120 is connected. The lower end of the water-sealing valve body 200 also cooperates with a second elastic element 270, which can be a spring, elastic rubber, silicone, etc. The second elastic element 270 can provide the water-sealing valve body 200 with an elastic force to make the first sealing ring 230 block the water passage hole 141, for example, by moving the water-sealing valve body 200 upward.

[0065] Next refer to Figure 7 and Figure 8 As shown, before button 400 is pressed, the first sealing ring 230 blocks the water passage hole 141, isolating the water inlet 110 and the water outlet channel 120. Then refer to... Figure 9 As shown, during the pressing of button 400, the inclined plane engages with latch 420 to drive turntable 300 to rotate. The rotation angle of turntable 300 can range from 3° to 30°. Finally, refer to... Figure 10 As shown, after the latch 420 and the inner wall of the first through hole 310 separate, the turntable 300 can be reset under the action of the reset mechanism 500, and the latch 420 and the lower wall of the turntable 300 are engaged, so that the button 400 remains in the pressed state, and at the same time the corresponding water passage 141 opens, and water flows out of the water outlet channel 120.

[0066] Reference Figure 11 As shown, turntable 300 is currently in its initial position. When button 400 pushes turntable 300 to rotate, refer to... Figure 12 As shown, the reset pin 510 and the reset inclined surface 321 abut against each other, providing a reset force to the turntable 300 to its initial position. When the latch 420 is located below the turntable 300, that is, the latch 420 and the inner wall of the first through hole 310 are separated, the turntable 300 can be reset to its initial position under the action of the reset pin 510 and the first elastic element 520, so that the latch 420 and the lower wall of the turntable 300 are engaged.

[0067] When switching to another water outlet channel 120, pressing another button 400 will also cause the turntable 300 to rotate. When the turntable 300 rotates to its maximum angle or close to its maximum angle, the latch 420 of the previously pressed button 400 loses the obstruction of the turntable 300 above. Therefore, under the elastic force of the second elastic element 270, the sealing valve body 200 drives the button 400 to rise, and then closes the water passage 141, thus cutting off the original water outlet channel 120. Meanwhile, the latch 420 of the other button 400 engages with the lower wall of the turntable 300, keeping the other water outlet channel 120 in a normally open state.

[0068] Understandably, by adopting the above scheme, a water distribution body 100 and multiple sealing valve bodies 200 are set up, and multiple buttons 400 are connected to the corresponding sealing valve bodies 200. By pressing the corresponding button 400, the sealing valve body 200 can open the corresponding water outlet channel 120. The operation is simple and convenient, and the reliability is good. Since the reset pin 510 is configured to elastically abut against the reset inclined surface 321 in a direction parallel to the rotation axis of the turntable 300, for example, the reset pin 510 abuts against the lower end face or the upper end face of the turntable 300, the turntable 300 and the wall surface of the water distribution body 100 can be kept in contact, reducing the possibility of the turntable 300 swaying or misaligning. At the same time, it can reduce the contact area between the turntable 300 and the water distribution body 100 or other components, reducing the friction of the turntable 300 during rotation. Therefore, it can improve the problems of uneven rotation, jamming, and strong damping of the turntable 300.

[0069] Reference Figure 3 and Figure 6 As shown in the embodiment of the present invention, the water distribution body 100 further includes an upper cover 150, an outer shell 160, and a bottom cover 130. The upper cover 150 is connected to the upper end of the main body 140, and a plurality of water outlet channels 120 are defined between the upper cover 150 and the main body 140. The outer shell 160 is located on the side of the upper cover 150 opposite to the main body 140, and The housing 160 is formed to accommodate multiple buttons. 400 inner cavity The bottom cover 130 is connected to the lower end of the main body 140, and the outer shell 160, the main body 140, and the bottom cover 130 can be connected by fasteners such as screws and bolts. The bottom cover 130 also has a connecting post 133, which passes through the main body 140 and the upper cover 150, and... The upper end of the connecting post 133 is located inside the cavity of the housing 160.In the middle, the turntable 300 is rotatably fitted onto the connecting column 133, meaning the turntable 300 can rotate around the connecting column 133. The water distribution body 100 also includes a pressure cap 180 and a buckle cap 170. The pressure cap 180 is connected to the connecting column 133 to prevent the turntable 300 from detaching from the connecting column 133. When the pressure cap 180 is connected to the connecting column 133 by fasteners such as screws or bolts, the buckle cap 170 is connected to the upper end of the pressure cap 180 to cover the fasteners and improve the overall aesthetics of the water control valve 1000.

[0070] Reference Figure 6 As shown, it can be understood that when the reset pin 510 and the first elastic element 520 are located below the turntable 300, the elastic force of the multiple first elastic elements 520 allows the turntable 300 and the pressure cap 180 to abut, thereby reducing the direct contact between the turntable 300 and structures such as the upper cover 150 or the main body 140, reducing friction, and also reducing the possibility of the turntable 300 swaying or misaligning. In another embodiment, the inner wall of the outer shell 160 may be provided with a positioning surface 161. Under the action of the multiple first elastic elements 520 and the reset pin 510, the turntable 300 abuts and is positioned with the positioning surface 161, which can also reduce the contact friction between the turntable 300 and the upper cover 150 or the main body 140, thus improving the smoothness of the turntable 300's rotation.

[0071] Reference Figure 3 and Figure 6 As shown in the embodiment of the present invention, the upper cover 150 is provided with a second through hole 151 through which the water sealing valve body 200 passes, and the bottom cover 130 is provided with a third through hole 132 for sliding engagement of the water sealing valve body 200. A second sealing ring 240 and a third sealing ring 250 are fitted onto the water sealing valve body 200. The second sealing ring 240 is located inside the second through hole 151, and the third sealing ring 250 is located inside the third through hole 132. Through the sealing engagement of the second sealing ring 240 and the third sealing ring 250, water leakage from the second through hole 151 or the third through hole 132 can be effectively prevented. In the embodiment of the present invention, the second through hole 151 and the third through hole 132 are coaxial and have the same inner diameter, and the areas of the second sealing ring 240 and the third sealing ring 250 subjected to water pressure are the same. This ensures that when the button 400 is in a water-stopped state, the pressing feel is not too heavy, improving the smoothness of pressing and providing a better user experience.

[0072] Reference Figure 4 As shown, in an embodiment of the present invention, the positioning part 320 is a raised rib, and the raised rib is provided with a first groove 322. The first groove 322 has reset inclined surfaces 321 formed on both sides of its wall surface along the rotation direction of the turntable 300. The two reset inclined surfaces 321 are arranged at an angle, which can be 120°. Figure 4 From the perspective of [the image], the first groove 322 is inverted V-shaped. Therefore, when the turntable 300 is in its initial position, [referencing] Figure 11 As shown, the top of the reset pin 510 is located in the middle of the first groove 322, which is the connection point of the two reset ramps 321. When the turntable 300 rotates under the drive of the latch 420, the reset pin 510 and one of the reset ramps 321 abut against each other, and at the same time, a reset force capable of resetting to the initial position is applied to the turntable 300.

[0073] Reference Figure 4 As shown, in the embodiment of the present invention, multiple ribs are provided, and the number is the same as the number of buttons 400, for example, three in each case. The three ribs are spaced apart around the rotation axis of the turntable 300, and are alternately arranged with multiple first through holes 310 along the rotation direction of the turntable 300; that is, a rib is provided between two adjacent first through holes 310. It can be understood that by providing multiple ribs, the stability of the turntable 300 during rotation can be improved, effectively reducing jamming, swaying, misalignment, and other issues. When one rib fails, the other ribs can still serve to reset the turntable.

[0074] Reference Figure 3 and Figure 4 As shown in the embodiment of the present invention, the protruding rib is an arc-shaped structure extending along the rotation direction of the turntable 300. The reset mechanism 500 includes a sleeve 530, a first elastic member 520 disposed within the sleeve 530, and a reset pin 510 slidably connected within the sleeve 530 and connected to the first elastic member 520. A second groove 531 is provided at one end of the sleeve 530 facing the protruding rib, allowing the protruding rib to slide through. The sleeve 530 serves to limit and guide the first elastic member 520, effectively preventing it from becoming loose or misaligned. The second groove 531 avoids the protruding rib, preventing it from getting stuck between the protruding rib and the sleeve 530, thus preventing the turntable 300 from rotating.

[0075] Reference Figure 3 As shown in the embodiment of the present invention, the reset pin 510 has a head, a middle section, and a tail connected in sequence. The head is spherical, the middle section is cylindrical with the same outer diameter as the maximum outer diameter of the head, and the tail is cylindrical with an outer diameter smaller than that of the middle section. The second elastic element 270 is a spring, which is fitted onto the tail and abuts against the bottom wall of the middle section. The outer diameter of the middle section is slightly smaller than the inner diameter of the sleeve 530, so that the reset pin 510 can slide within the sleeve 530 while reducing the deflection angle of the reset pin 510 and improving the guiding accuracy of the reset pin 510.

[0076] Reference Figure 8As shown in the embodiment of the present invention, the latch 420 has a first guide surface 421 on the side opposite to the pressing surface 410, and a second guide surface 311 is provided on the inner wall of the first through hole 310. Both the first guide surface 421 and the second guide surface 311 are inclined surfaces and can guide and cooperate, so that when the button 400 is pressed, it abuts against the first guide surface 421 and the second guide surface 311, thereby driving the turntable 300 to rotate. It should be noted that the entire inner wall of the first through hole 310 constitutes the second guide surface 311, and the second guide surface 311 is arranged around the first through hole 310. In another embodiment, a portion of the inner wall of the first through hole 310 may also constitute the second guide surface 311, depending on the actual situation.

[0077] Continue to refer to Figure 8 As shown in the embodiment of the present invention, along the direction in which the button 400 is pressed, the inner wall of the first through hole 310 is sequentially provided with a first guide surface 421 and a transition surface 312, the transition surface 312 extending vertically. It can be understood that when the button 400 is pressed down to the position where the latch 420 and the transition surface 312 abut, for example, by pressing the button 400 down a distance H1 (H1 is the distance between the pressing surface 410 when the button 400 is not pressed and the pressing surface 410 after the button 400 is pressed), the turntable 300 rotates to its maximum rotation angle, causing another pressed button 400 to spring back to its original position under the elastic force of the second elastic element 270. If the button 400 is released instead of pressed further, all buttons 400 are in the spring-up state, meaning all water outlet channels 120 are closed. If the button 400 is pressed to a distance of H2 (H2 is the distance between the pressing surface 410 when the button 400 is not pressed and the pressing surface 410 after the button 400 is pressed), when the latch 420 is inserted into the through hole, the pressed latch 420 engages with the lower wall of the turntable 300, thereby keeping the corresponding water outlet channel 120 normally open.

[0078] Reference Figure 4 As shown in the embodiment of the present invention, the head of the sealing valve body 200 includes a boss 260 and a positioning rib 261 surrounding the boss 260. The button 400 has a central hole 430 and a notch 440 communicating with the central hole 430 on the side opposite to the pressing surface 410. The boss 260 is engaged with the central hole 430, and the positioning rib 261 and the notch 440 are engaged, thereby restricting the rotation of the button 400. By adopting the above solution, the stability of the connection between the button 400 and the sealing valve body 200 can be improved, and the installation is convenient and the assembly efficiency is high.

[0079] In related technologies, water control valves typically allow only one water outlet to flow when controlling water output from different channels, and simultaneous pressing of multiple buttons is not permitted. However, due to user curiosity or other reasons, multiple buttons may be pressed simultaneously, causing multiple water outlets to open. Alternatively, if one button is pressed, another button may not spring back as intended due to friction, assembly inaccuracies, deformation, or jamming, resulting in simultaneous water output from multiple channels and affecting product quality.

[0080] To reduce the problem of multiple 120 water outlets simultaneously discharging water, refer to... Figure 3 , Figure 4 and Figure 13 As shown in the embodiment of the present invention, the water distribution body 100 is provided with a plurality of positioning posts 540 at one end facing the turntable 300. The plurality of positioning posts 540 are evenly distributed around the rotation axis of the turntable 300, for example, there are three positioning posts 540. The positioning posts 540 can be sleeves 530, that is, the positioning posts 540 and the sleeves 530 are the same component. In another embodiment, the positioning posts 540 and the sleeves 530 can also be two different components. The water control valve 1000 also includes a plurality of stop rotors 600, which are respectively fitted onto the corresponding positioning posts 540, so that the stop rotors 600 can move along the rotation direction of the turntable 300. The sealing valve body 200 includes an anti-rotation section 210. The anti-rotation section 210 is configured such that, in any water discharge state of the control valve 1000, only one anti-rotation section 210 is pressed. Furthermore, the anti-rotation section 210 can push two adjacent stop rotors 600 to move, thereby restricting the pressing of the anti-rotation sections 210 of adjacent sealing valve bodies 200. This ensures that only one button 400 can be pressed to allow water to flow from the outlet channel 120. The control valve 1000 has a reasonable structural design and high reliability.

[0081] The structure of the stop rotor 600 can be referred to Figure 4 As shown in the embodiment of the present invention, the anti-rotation section 210 includes a third groove 211 extending axially along the sealing valve body 200, and a third guide surface 212 is provided at one end of the third groove 211 near the latch 420. The stop rotor 600 has a fourth guide surface 620 at both ends along the rotation direction of the turntable 300. The fourth guide surface 620 is located on the side of the stop rotor 600 facing the latch 420, that is, on the upper side of the stop rotor 600. The fourth guide surface 620 can slide and engage with the corresponding third guide surface 212. Both the third guide surface 212 and the fourth guide surface 620 are inclined surfaces, and the engagement between the inclined surfaces allows the stop rotor 600 to move.

[0082] During the operation of the stop rotor 600, refer to the following in sequence: Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, during the process of pressing button 400, from Figures 7 to 9 As shown in the diagram, the third guide surface 212 and the fourth guide surfaces 620 of the stop rotors on both sides move from a separated state to a contact state. When the button 400 is pressed down further, refer to... Figure 10 As shown, through the cooperation of the third guide surface 212 and the fourth guide surface 620, the stop rotors 600 on both sides can be pushed to move to the third groove 211 close to the adjacent sealing valve body 200. At the same time, one end of the stop rotor 600 along the rotation direction of the turntable 300 disengages from the third groove 211 and abuts against the outer wall of the anti-rotation section 210, while the other end of the stop rotor 600 is located in the third groove 211 of another anti-rotation section 210. That is, to keep the water outlet channel 120 open, when the button 400 is pressed, the stop rotor 600 can be squeezed out of the third groove 211 and abut against the outer wall of the anti-rotation section 210 through the cooperation of the third guide surface 212 and the fourth guide surface 620. At this time, it can be ensured that the latch 420 crosses the transition surface 312 of the first through hole 310 and engages with the lower wall of the turntable 300.

[0083] For ease of explanation, the two adjacent buttons 400 are named the first button and the second button, respectively. Assuming the first button has been pressed, and the user wants to press the second button at the same time, pressing the second button requires the stop rotor 600 to be squeezed out of the third groove 211. However, the outer wall of the anti-rotation section 210 of the sealing valve body 200 connected to the first button is already in contact with the end of the stop rotor 600. Therefore, when the second button is pressed, the end of the stop rotor 600 cannot be squeezed out of the third groove 211. As a result, the latch 420 of the second button cannot pass through the transition surface 312 of the first through hole 310, so that the second button will return to the closed position of the corresponding water outlet channel 120 after being released.

[0084] In another scenario, assuming all buttons 400 are not pressed, when the user presses the first and second buttons simultaneously, the stop rotor 600 needs to be pushed out of the third groove 211 and abut against the outer wall of the anti-rotation section 210 so that the latch 420 can pass over the transition surface 312 of the first through hole 310 and engage with the lower wall of the turntable 300. However, when the first and second buttons are pressed simultaneously, the stop rotor 600 located between the first and second buttons will move towards each other, thus preventing the first and second buttons from being pressed.

[0085] In another scenario, assuming the first button is pressed and the user wants to switch the water flow status by pressing the second button, the first button should normally spring up under the elastic force of the second elastic element 270. However, due to friction, jamming, or other reasons, the first button does not spring up as expected, but only rises a short distance before getting stuck. During the pressing of the second button, the stop rotor 600 is pressed towards the first button. Through the cooperation of the third and fourth inclined surfaces, an upward force can be applied to the sealing valve body 200 connected to the first button, thereby causing the first button to rise and improving the success rate of the first button's reset.

[0086] When the above solution is adopted, it can effectively reduce the situation where multiple buttons 400 are pressed at the same time, resulting in multiple water outlet channels 120 flowing out water at the same time. It can also improve the reset success rate of buttons 400, reduce the impact of jamming, high friction and other issues, and improve the reliability of water control valve 1000.

[0087] Reference Figure 13 As shown, in the embodiment of the present invention, there are three sealing valve bodies 200 and three stop rotors 600, all distributed around the rotation axis of the turntable 300. The stop section 210 also includes a shaft section 213, the outer wall of which forms part of the wall surface of the third groove 211. Taking the rotation center of the turntable 300 as the center and the distance from the center to the central axis of the sealing valve body 200 as the radius, draw a circle. The arc length passing through the central axis between two adjacent sealing valve bodies 200 is L1, the arc length passing through the two ends of the stop rotor 600 is L2, and the arc length passing through the end of the stop rotor 600 near the shaft section 213 and the wall surface of the shaft section 213 is L3. The radius of the shaft section 213 is R, satisfying 3*L1=(L2+L3+2R)*3. Understandably, with the above-mentioned size design, when one of the buttons 400 is pressed, it can push one end of the stop rotor 600 to engage with the third groove 211 of the adjacent sealing valve body 200, ensuring that adjacent buttons 400 cannot be pressed at the same time.

[0088] Reference Figure 4 and Figure 13 As shown in the embodiment of the present invention, the turntable 300 is provided with a central column 330, and the stop rotor 600 is provided with an arc surface that slides with the central column 330. Therefore, when the anti-rotation segment 210 pushes the stop rotor 600 to move, the arc surface plays a guiding role, and the stop rotor 600 can rotate around the rotation axis of the turntable 300.

[0089] Reference Figure 13As shown, in an embodiment of the present invention, the stop rotor 600 is provided with an elongated hole 610. The elongated hole 610 is elongated, and the positioning post 540 passes through the elongated hole 610. The extending direction of the elongated hole 610 coincides with the moving trajectory of the stop rotor 600, or in other words, the extending direction of the elongated hole 610 is the same as the rotation direction of the turntable 300. It can be understood that the elongated hole 610 has a guiding function, enabling the stop rotor 600 to move along the extending direction of the elongated hole 610, thereby preventing multiple buttons 400 from being pressed simultaneously and improving the reliability of the water control valve 1000.

[0090] In addition to using a stop rotor 600 to ensure that multiple buttons 400 are not pressed simultaneously, refer to Figure 14 and Figure 15 As shown, in another embodiment of the present invention, the water control valve 1000 further includes a swing member 700, which is disposed within the water distribution body 100. The swing member 700 includes a support column 710 and a plurality of levers 720 arranged around the center line of the support column 710, for example, three levers 720. The number of levers 720 is the same as the number of sealing valve bodies 200. The plurality of levers 720 are respectively connected to the corresponding sealing valve bodies 200 and are configured such that in any water outlet state of the water control valve 1000, only one lever 720 is pressed, so that the water control valve 1000 has at most one water outlet channel 120 open. For example, see reference. Figure 16 and Figure 17 As shown, when one of the buttons 400 is pressed, the sealing valve body 200 drives a lever 720 to tilt downward, so that the corresponding lever 720 is in the pressed state, while the other lever 720 is in the tilted state. Therefore, it can effectively ensure that only one water outlet channel 120 can output water at most.

[0091] Reference Figure 14 As shown in the embodiment of the present invention, the lever 720 is provided with a socket 721, and the water sealing valve body 200 is provided with a fourth groove 220, which corresponds to and engages with the socket 721. The lever 720 moves by abutting against the inner wall of the fourth groove 220, thus making the installation process of the lever 720 and the water sealing valve body 200 simple, convenient, and highly reliable.

[0092] Reference Figure 14 and Figure 17 As shown in the embodiment of the present invention, the bottom wall of the water distribution body 100, that is, the inner bottom wall of the bottom cover 130, is provided with a recessed platform 131. The recessed platform 131 is in the shape of a pit. The end of the support column 710 that cooperates with the recessed platform 131 is spherical, so that the swing member 700 can swing. When one of the levers 720 is pressed, the other levers 720 are raised, thereby preventing multiple buttons 400 from being pressed at the same time.

[0093] A water outlet device according to one embodiment of the present invention includes the water control valve 1000 of the above embodiment. The water outlet device can be a shower head, shoulder spray, waist spray, overhead spray, etc. The water outlet device of this embodiment uses the water control valve 1000 of the above embodiment. The water control valve 1000 is configured with a water distribution body 100 and multiple sealing valve bodies 200, and multiple buttons 400 are connected to the corresponding sealing valve bodies 200. By pressing the corresponding button 400, the sealing valve body 200 can open the corresponding water outlet channel 120. The turntable 300 can rotate relative to the water distribution body 100. When a button 400 is pressed, the latch 420 of the button 400 abuts against and pushes the turntable 300 to rotate, causing the turntable 300 to drive the reset inclined surface 321 of the positioning part 320 to press the reset pin 510 and the elastic element, and the elastic element is in a compressed state. When the latch 420 of button 400 passes through the first through hole 310 of turntable 300, the latch 420 separates from the inner wall of the first through hole 310. Turntable 300 can be reset to its initial position under the elastic force of reset pin 510 and elastic element. After release, latch 420 can be engaged with the lower end face of turntable 300, so that button 400 and water sealing valve body 200 remain in the pressed state, and the corresponding water outlet channel 120 can continuously output water. Since the reset pin 510 is configured to elastically abut against the reset inclined surface 321 in a direction parallel to the rotation axis of turntable 300, the wall surface of turntable 300 and water distribution body 100 can be kept in contact, reducing the possibility of turntable 300 swaying and misalignment. At the same time, it can reduce the contact area between turntable 300 and water distribution body 100 or other components, reducing the friction of turntable 300 during rotation. Therefore, it can improve the problems of uneven rotation, jamming and strong damping of turntable 300.

[0094] Since the water outlet device adopts all the technical solutions of the water control valve 1000 in the above embodiments, it has at least all the beneficial effects brought about by the technical solutions in the above embodiments, which will not be repeated here.
