Referring to fig. 3, the reset mechanism 500 is provided to the water diversion main body 100, and the reset mechanism 500 includes a reset pin 510 and a first elastic member 520 acting on the reset pin 510, the first elastic member 520 may be a spring, a silica gel having elasticity, rubber, or the like, and the reset pin 510 is configured to elastically abut against the reset slope 321 in a direction parallel to the rotation axis of the turntable 300. By the abutting engagement of the reset pin 510 and the reset ramp 321, a reset force can be provided to the turntable 300 such that the turntable 300 is reset to the initial position.

Referring to fig. 5 and 6, the water sealing body includes a body part 140, the body part 140 is provided with a plurality of water passing holes 141, the number of the water passing holes 141 is the same as that of the water outlet passages 120, and the water inlet 110 is communicated with the water outlet passages 120 through the corresponding water passing holes 141. The water sealing valve body 200 is provided with a first sealing ring 230, and the first sealing ring 230 can be in sealing fit with the water passing hole 141, so that the corresponding water outlet channel 120 is sealed. When the key 400 is pressed, the water sealing valve body 200 can be driven to move downwards, so that the first sealing ring 230 opens the water passing hole 141, and at the moment, the corresponding water outlet channel 120 is connected. The lower end of the water sealing valve body 200 is also engaged with a second elastic member 270, and the second elastic member 270 may be a spring, rubber having elasticity, silicone, or the like. The second elastic member 270 may provide an elastic force to the sealing valve body 200 such that the first sealing ring 230 seals the water hole 141, for example, to move the sealing valve body 200 upward.

Referring to fig. 7 and 8, before the key 400 is pressed, the first sealing ring 230 seals the water passing hole 141 to block the water inlet 110 and the water outlet 120. Then referring to fig. 9, in the process of pressing the key 400, the button position 420 pushes the turntable 300 to rotate by using the cooperation of the inclined planes, and the rotation angle of the turntable 300 can be 3 ° -30 °; finally, referring to fig. 10, after the button 420 is separated from the inner wall of the first through hole 310, the turntable 300 can be reset under the action of the reset mechanism 500, and the button 420 is clamped to the lower wall surface of the turntable 300, so that the button 400 is kept in a pressed state, and meanwhile, the corresponding water through hole 141 is opened, and the water outlet channel 120 is discharged.

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 in the sleeve 530, the deflection angle of the reset pin 510 can be reduced, and the guiding accuracy of the reset pin 510 is improved.

Referring to fig. 8, in the embodiment of the invention, a first guiding surface 421 is disposed on a side of the button 420 facing away from the pressing surface 410, and a second guiding surface 311 is disposed on an inner wall of the first through hole 310, where the first guiding surface 421 and the second guiding surface 311 are both inclined surfaces and can be in guiding fit, so that when the button 400 is pressed, the first guiding surface 421 and the second guiding surface 311 abut against each other, thereby driving the turntable 300 to rotate. The entire inner wall of the first through hole 310 forms a second guide surface 311, and the second guide surface 311 is disposed around the first through hole 310. In another embodiment, a part of the inner wall of the first through hole 310 may form the second guiding surface 311, and a suitable scheme is specifically selected according to practical situations.

With continued reference to fig. 8, in the embodiment of the present invention, along the direction in which the key 400 is pressed, the inner wall of the first through hole 310 is sequentially provided with a first guiding surface 421 and a transition surface 312, and the transition surface 312 is disposed to extend in the vertical direction. It can be understood that when the key 400 is pressed down to a position where the button 420 abuts against the transition surface 312, for example, the key 400 is pressed down by a distance H1 (H1 is a distance between the pressing surface 410 when the key 400 is not pressed and the pressing surface 410 after the key 400 is pressed), the turntable 300 rotates to a maximum rotation angle, so that the other pressed key 400 is sprung and returns under the elastic force of the second elastic member 270. At this time, if the key 400 is not continuously pressed but is released, all the keys 400 are in a sprung state, i.e., all the water outlet passages 120 are closed. If the distance from the button 400 to the button H2 is continuously pressed (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 button 420 is inserted into the through hole, the pressed button 420 is engaged with the lower wall surface of the turntable 300, so that the corresponding water outlet channel 120 is kept normally open.

Referring to fig. 4, in the embodiment of the present invention, the head of the water sealing valve body 200 includes a boss 260 and a positioning rib 261 disposed around the boss 260, a central hole 430 and a notch 440 communicating with the central hole 430 are disposed on a side of the key 400 facing away from the pressing surface 410, the boss 260 is clamped to the central hole 430, and the positioning rib 261 is clamped to the notch 440, so as to limit rotation of the key 400. By adopting the scheme, the stability of connection between the key 400 and the water sealing valve body 200 can be improved, the installation is convenient, and the assembly efficiency is high.

In the related art, when the water control valve controls water outlet of different water outlet channels, only one water outlet channel is usually allowed to outlet water, but the condition that a plurality of keys are pressed simultaneously is not allowed to exist. However, there are cases where a plurality of water outlet channels are opened due to the user pressing a plurality of keys simultaneously for curiosity and the like. Or one of the keys is pressed down, and the other key is not sprung up in an expected mode due to friction force, assembly precision, deformation, clamping and the like, so that a plurality of water outlet channels can simultaneously discharge water, and the product quality is affected.

In order to reduce the problem of simultaneous water discharge from the plurality of water discharge channels 120, referring to fig. 3, 4 and 13, in the embodiment of the present invention, a plurality of positioning posts 540 are disposed at one end of the water diversion body 100 facing the turntable 300, and the plurality of positioning posts 540 are uniformly disposed around the rotation axis of the turntable 300, for example, three positioning posts 540 are disposed. Wherein, the positioning post 540 may be the sleeve 530, that is, the positioning post 540 and the sleeve 530 are the same component. In another embodiment, the positioning post 540 may be two distinct components from the sleeve 530. The water control valve 1000 further includes a plurality of stop rotors 600, and the plurality of stop rotors 600 are respectively sleeved on the corresponding positioning posts 540, so that the stop rotors 600 can move along the rotation direction of the turntable 300. The water sealing valve body 200 comprises rotation stopping sections 210, wherein the rotation stopping sections 210 are configured such that only one rotation stopping section 210 is pressed down in any water outlet state of the water control valve 1000, and the rotation stopping sections 210 can push two adjacent rotation stopping rotors 600 to move so as to limit the rotation stopping sections 210 of the adjacent water sealing valve bodies 200 to be pressed down. Thereby ensuring that only one key 400 can be pressed to enable the water outlet channel 120 to outlet water, the structural design of the water control valve 1000 is reasonable, and the reliability is high.

In the embodiment of the present invention, the rotation stop section 210 includes a third groove 211 extending along the axial direction of the water sealing valve body 200, and a third guiding surface 212 is disposed at one end of the third groove 211 near the fastening position 420. The two ends of the stop rotor 600 along the rotation direction of the turntable 300 are respectively provided with a fourth guiding surface 620, the fourth guiding surface 620 is located on one side of the stop rotor 600 facing the buckling position 420, that is, on the upper side of the stop rotor 600, and the fourth guiding surface 620 can be in sliding fit with the corresponding third guiding surface 212. Wherein, the third guiding surface 212 and the fourth guiding surface 620 are inclined surfaces, and the stop rotor 600 can be pushed to move by the cooperation between the inclined surfaces.

During the operation of the stopper rotor 600, referring to fig. 7, 8, 9 and 10 in order, the third guide surface 212 and the fourth guide surfaces 620 of the stopper rotor 600 on both sides are brought into contact with each other from the separated state as shown in the state of fig. 7 to 9 in the process of pressing the key 400. When the key 400 is continuously pressed, as shown in fig. 10, the stop rotors 600 at both sides can be pushed to move to the third grooves 211 close to the adjacent water sealing valve body 200 by the cooperation of the third guide surface 212 and the fourth guide surface 620, and meanwhile, one end of the stop rotor 600 along the rotation direction of the turntable 300 is separated from the third grooves 211 and is abutted with the outer side wall of the rotation stopping section 210, and the other end of the stop rotor 600 is positioned in the third groove 211 of the other rotation stopping section 210. That is, when the key 400 is required to be pressed in order to keep the water outlet passage 120 normally open, the stopper rotor 600 can be pushed out of the third groove 211 by the engagement of the third guide surface 212 and the fourth guide surface 620 and can abut against the outer wall of the rotation stopping section 210, and at this time, the snap-in position 420 can be ensured to pass over the transition surface 312 of the first through hole 310 and to be engaged with the lower wall surface of the turntable 300.

For convenience of description, two adjacent keys 400 are respectively designated as a first key and a second key, and assuming that the first key has been pressed, the user presses the first key and presses the second key, and the pressing of the second key requires that the stop rotor 600 is extruded out of the third groove 211, but the outer sidewall of the rotation stop section 210 of the water sealing valve body 200 connected with the first key is abutted with the end of the stop rotor 600, so that when the second key is pressed, the end of the stop rotor 600 cannot be extruded out of the third groove 211, and therefore the buckling position 420 of the second key cannot cross the transition surface 312 of the first through hole 310, so that the second key can be reset to the position where the corresponding water outlet channel 120 is closed after the second key is released.

In another case, assuming that all the keys 400 are not pressed, when the user presses the first key and the second key simultaneously, the stop rotor 600 needs to be extruded out of the third groove 211 and abuts against the outer side wall of the rotation stop section 210, and the fastening position 420 can pass over the transition surface 312 of the first through hole 310 and be fastened to the lower wall surface of the turntable 300. However, when the first key and the second key are pressed simultaneously, the stop rotor 600 between the first key and the second key is moved in a direction approaching to each other, so that neither the first key nor the second key can be pressed.

In another case, assuming that the first key is pressed, when the user wants to switch the water outlet state and presses the second key, the first key needs to be sprung under the action of the elastic force of the second elastic member 270 under normal conditions, but due to friction force, blocking and other reasons, the first key is not sprung according to the expected condition, but only a small distance is lifted to be blocked, when the second key is pressed, the stop rotor 600 is pressed towards the direction of the first key, and by the cooperation of the third inclined plane and the fourth inclined plane, an upward force can be given to the water sealing valve body 200 connected with the first key, so that the first key is driven to lift, and the success rate of resetting the first key is improved.

By adopting the scheme, the situation that a plurality of keys 400 are pressed simultaneously to lead to a plurality of water outlet channels 120 to outlet water simultaneously can be effectively reduced, the reset success rate of the keys 400 can be improved, the influence caused by the conditions of blocking, large friction force and the like is reduced, and the reliability of the water control valve 1000 is improved.

Referring to fig. 13, in the embodiment of the present invention, the water sealing valve body 200 and the stopper rotor 600 are provided with three, and are distributed around the rotation axis of the turntable 300. The rotation stopping section 210 further includes a shaft section 213, and the outer wall of the shaft section 213 forms part of the wall surface of the third groove 211. The distance from the center of rotation of the turntable 300 to the central axis of the water sealing valve body 200 is the radius to draw a circle, and the arc length passing between the central axes of two adjacent water sealing valve bodies 200 is L ₁ The arc length passing between the two ends of the stop rotor 600 is L ₂ An arc length L passing between one end of the stop rotor 600 near the shaft section 213 and the wall surface of the shaft section 213 ₃ The radius of the shaft segment 213 is R, which satisfies 3*L ₁ =（L ₂ +L ₃ +2r) 3. It will be appreciated that with the above-described size design, when one of the keys 400 is pressed, one end of the stopper rotor 600 can be pushed to cooperate with the third recess 211 of the adjacent sealing valve body 200, ensuring that the adjacent key 400 cannot be pressed simultaneously.

Referring to fig. 4 and 13, in the embodiment of the present invention, the turntable 300 is provided with a center post 330, and the stopper rotor 600 is provided with an arc surface slidably engaged with the center post 330. The arc surface plays a guiding role when the rotation stop section 210 pushes the rotation stop rotor 600 to move, and the rotation stop rotor 600 can rotate around the rotation axis of the rotating disc 300.

Referring to fig. 13, in the embodiment of the present invention, the stopper rotor 600 is provided with a long hole 610, the long hole 610 is long, the positioning post 540 is penetrating through the long hole 610, and the extending direction of the long hole 610 coincides with the moving track of the stopper rotor 600, or the extending direction of the long hole 610 is the same as the rotating direction of the turntable 300. It will be appreciated that the elongated hole 610 has a guiding function, so that the stopper rotor 600 can move along the extending direction of the elongated hole 610, thereby preventing the plurality of keys 400 from being simultaneously pressed, and improving the reliability of the water control valve 1000.

In addition to adopting the stopper rotor 600 to ensure that the plurality of keys 400 are not simultaneously pressed, referring to fig. 14 and 15, in another embodiment of the present invention, the water control valve 1000 further includes a swinging member 700, the swinging member 700 is disposed in the water diversion body 100, the swinging member 700 includes a pillar 710 and a plurality of paddles 720 disposed around a center line of the pillar 710, for example, three paddles 720, the number of paddles 720 is the same as that of the water sealing valve bodies 200, the plurality of paddles 720 are respectively connected with the corresponding water sealing valve bodies 200, and are configured such that only one of the paddles 720 is pressed in any water outlet state of the water control valve 1000, so that the water control valve 1000 has only one water outlet passage 120 at most. For example, referring to fig. 16 and 17, when one of the keys 400 is pressed, one of the dials 720 is driven to deflect downward by the water sealing valve body 200, so that the corresponding dial 720 is in a pressed state, and the other dials 720 are in a tilted state, thereby effectively ensuring that at most one water outlet channel 120 is discharged.

Referring to fig. 14, in the embodiment of the present invention, the dial 720 is provided with a socket 721, the water sealing valve body 200 is provided with a fourth groove 220, and the fourth groove 220 and the socket 721 are correspondingly matched. The inner wall of the fourth groove 220 is abutted with the poking piece 720, so that the poking piece 720 is driven to move, and the poking piece 720 and the water sealing valve body 200 are simple and convenient in installation process and high in reliability.

Referring to fig. 14 and 17, in the embodiment of the present invention, the bottom wall of the water diversion body 100, that is, the inner bottom wall of the bottom cover 130 is provided with a sink 131, and the sink 131 is in a pit shape; the end of the post 710, which is engaged with the sinking stage 131, is spherical so that the swinging member 700 can swing. When one of the dials 720 is pressed, the other dials 720 are tilted, thereby preventing the plurality of keys 400 from being pressed at the same time.

The water outlet device of an embodiment of the present invention includes the water control valve 1000 of the above embodiment, and the water outlet device may be a shower, a shoulder spray, a waist spray, a top spray, etc. The water outlet device of the embodiment of the invention adopts the water control valve 1000 of the embodiment, and the water control valve 1000 is connected with the corresponding water sealing valve body 200 by arranging the water diversion main body 100 and the plurality of water sealing valve bodies 200 and a plurality of keys 400. By pressing the corresponding key 400, the water sealing valve body 200 can be caused to open the corresponding water outlet passage 120. The rotary table 300 can rotate relative to the water diversion main body 100, when the key 400 is pressed, the button position 420 of the key 400 abuts against and pushes the rotary table 300 to rotate, so that the rotary table 300 drives the reset inclined plane 321 of the positioning part 320 to squeeze the reset pin 510 and the elastic piece, and the elastic piece is in a compressed state. After the button position 420 of the button 400 passes through the first through hole 310 of the turntable 300, the button position 420 is separated from the inner wall of the first through hole 310, the turntable 300 can be reset to the initial position under the action of the elastic force of the reset pin 510 and the elastic element, and after the button is loosened, the button position 420 can be clamped to the lower end face of the turntable 300, so that the button 400 and the water sealing valve body 200 are kept in a pressed state, and the corresponding water outlet channel 120 can continuously outlet water. Because 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, the turntable 300 and the wall surface of the water diversion main body 100 can be kept in abutment, so that the condition that the turntable 300 is easy to deflect and misplace is reduced, meanwhile, the contact area between the turntable 300 and the water diversion main body 100 or other components can be reduced, and the friction force of the turntable 300 in the rotation process is reduced, thus the problems of unsmooth rotation of the turntable 300, clamping and strong damping feeling and the like can be improved.

Because the water outlet device adopts all the technical schemes of the water control valve 1000 in the above embodiment, at least the water outlet device has all the beneficial effects brought by the technical schemes in the above embodiment, and the description thereof is omitted.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present invention.
