Referring to fig. 3 and 4, a water control valve 1000 according to an embodiment of the present invention includes a housing 100, a rotary table 200, a driving assembly 400, and a plurality of spray heads 300, wherein the housing 100 includes an upper housing part 102 and a lower housing part 101, the lower housing part 101 is fixedly connected to a face cover 2200, the upper housing part 102 is connected to the lower housing part 101, a mounting cavity 120 is formed between the upper housing part 102 and the lower housing part 101, and the upper housing part 102 is further provided with a first water inlet 110 communicating with the mounting cavity 120. The upper housing portion 102 is also connected to the annular portion 2160 such that the water passage chamber 2130 communicates with the first water inlet 110. The turntable 200 is disposed in the installation cavity 120, and the turntable 200 can reciprocally rotate with respect to the housing 100 about a rotation axis, for example, a support column 180 is disposed at a bottom wall of the installation cavity 120, and the turntable 200 is provided with a rotation portion 240, and the rotation portion 240 is rotatably connected to the support column 180. The turntable 200 is provided with a plurality of mounting locations 210, the plurality of mounting locations 210 being disposed about an axis of rotation. A plurality of spray heads 300 are correspondingly installed on the installation site 210, and a water spray channel 301 of the spray heads 300 communicates with the installation cavity 120. The plurality of spray heads 300 can repeatedly change the water outlet direction under the reciprocating rotation of the turntable 200. The driving assembly 400 is disposed in the installation cavity 120, and the driving assembly 400 includes a first impeller 410 and a transmission mechanism 420, wherein the first impeller 410 can rotate under the action of the water flow of the first water inlet 110, and drives the turntable 200 to rotate reciprocally through the transmission mechanism 420.
It will be appreciated that water enters the mounting chamber 120 from the first water inlet 110 and finally exits the water spray channel 301 of the spray head 300. The water flow drives the first impeller 410 to rotate, and the first impeller 410 drives the turntable 200 to reciprocate along the rotation axis through the transmission mechanism 420. Since the plurality of spray heads 300 are correspondingly mounted on the plurality of mounting positions 210 of the turntable 200, when the turntable 200 reciprocally rotates, the positions of the spray heads 300 can be driven to change, so as to change the water outlet direction, for example, when the spray heads 300 are used for water outlet, water can be discharged along the vertical direction, as shown in fig. 4, and the dash-dot line in fig. 4 indicates the water flow direction. When the spray head 300 discharges water, the water can be discharged in an inclined direction, as shown in fig. 5, and the dash-dot line in fig. 5 indicates the flow direction of the water. The water outlet direction of the spray head 300 is alternately changed between the water outlet in the vertical direction and the water outlet in the inclined direction by the reciprocating rotation of the rotary table 200. The plurality of mounting locations 210 are disposed around the rotation axis of the turntable 200, so that the plurality of spray heads 300 are also disposed around the rotation axis of the turntable 200, and when the water outlet direction of the spray heads 300 is inclined, the water outlet state of the water control valve 1000 is a weaving water type; when the water outlet direction of the spray head 300 is vertical, the water outlet state of the water control valve 1000 is vertical water type. Through the reciprocal rotation of carousel 200 for water control valve 1000 switches repeatedly between weaving water type and vertical water type, and visual effect is better, and is pleasing to the eye degree high. Meanwhile, the change of the water outlet direction of the spray head 300 can increase the flushing area of the water control valve 1000 and massage the skin of different positions of a user, so that the massage effect is improved, and the use experience of the user is better.
Referring to fig. 6 and 7, in the embodiment of the present invention, the transmission mechanism 420 includes a worm 422, a worm wheel 421 and a cam 423, the first impeller 410 is fixedly connected to the worm 422, the rotation axis of the first impeller 410 coincides with the rotation axis of the worm 422, the worm 422 is in transmission connection with the worm wheel 421, and the rotation axis of the worm 422 is perpendicular to the rotation axis of the worm wheel 421. The cam 423 is fixedly connected with the worm wheel 421, and the cam 423 can drive the turntable 200 to reciprocate. When the first impeller 410 is driven to rotate by the water flow, the worm 422 can be driven to synchronously rotate, and then the worm wheel 421 is driven to rotate. When the worm wheel 421 rotates, the cam 423 is driven to rotate, so that the protruding part of the cam 423 repeatedly abuts against the rotary table 200, so that the rotary table 200 reciprocally rotates, and the water outlet direction of the spray heads 300 is changed.
It can be appreciated that the cam 423 is driven to rotate by adopting the worm wheel 421 and the worm 422, so that the speed is reduced, and the whole volume of the transmission mechanism 420 can be reduced, so that the water control valve 1000 is more compact in structure and suitable for being applied to a device with a smaller installation space such as the shower head 2000. In another embodiment of the present invention, instead of using the worm wheel 421 and the worm 422, a plurality of gears may be used to cooperate, for example, the first impeller 410 drives the corresponding gear and the cam 423 to rotate, so as to drive the turntable 200 to reciprocate.
Referring to fig. 8 and 9, in the embodiment of the present invention, the turntable 200 includes a first arm 220 and a second arm 230 located at two circumferential sides of the cam 423, and when the protrusion of the cam 423 abuts against the first arm 220, the water outlet direction of the spray head 300 is inclined with respect to the rotation axis of the turntable 200, that is, the water outlet direction of the spray head 300 and the rotation axis of the turntable 200 form an included angle; when the protruding portion of the cam 423 is rotated to a position abutting against the second arm 230, the water outlet direction of the sprinkler head 300 is parallel to the rotation axis of the turntable 200.
For convenience of explanation, when the protruding portion of the cam 423 is abutted against the first arm 220, as shown in fig. 8, the cam 423 is in the first position; when the cam 423 is rotated in the counterclockwise direction to a position between the first arm 220 and the second arm 230 with the protruding portion of the cam 423 toward the rotation center of the turntable 200, the cam 423 is in the second position; when the cam 423 rotates in the counterclockwise direction to a position abutting the second arm 230, as shown in fig. 9, the cam 423 is in the third position; when the cam 423 is rotated between the second arm 230 and the first arm 220 in the counterclockwise direction and the protruding portion of the cam 423 is away from the rotation center of the turntable 200, the cam 423 is in the fourth position. I.e., the cam 423 may alternate in a counterclockwise direction between a first position, a second position, a third position, and a fourth position.
When the cam 423 is in the second position, a first angle between the water outlet direction of the spray head 300 and the rotation axis of the turntable 200 is equal to a second angle between the water outlet direction of the spray head 300 and the rotation axis of the turntable 200 when the cam 423 is in the first position. When the cam 423 is in the fourth position, the water outlet direction of the spray head 300 is parallel to the rotation axis of the dial 200. That is, when the cam 423 is at the first position and the second position, the water outlet direction of the nozzle 300 is inclined; when the cam 423 is in the third and fourth positions, the water outlet direction of the sprinkler 300 is vertical. By adopting the scheme, the user can conveniently see the water type change of the water control valve 1000, the situation that the user cannot feel due to the fact that the time of one water type is too short is effectively improved, the massage and flushing effects can be improved, and the use experience of the user is improved.
In another embodiment, when the protruding portion of the cam 423 abuts against the first arm 220 or the second arm 230, the water outlet direction of the spray head 300 is disposed at an angle with respect to the rotation axis of the turntable 200. Although the water outlet direction is inclined, the direction of inclination is different; when the protruding portion of the cam 423 is separated from the first arm 220 and the second arm 230, the water outlet direction of the spray head 300 is parallel to the rotation axis of the turntable 200, and a proper water outlet mode is specifically selected according to practical situations.
Referring to fig. 6 and 10, in the embodiment of the invention, the water control valve 1000 further includes a gasket 500, the gasket 500 includes a bottom plate 510 and a plurality of elastic seats 520, the bottom plate 510 is annular, the plurality of elastic seats 520 are connected to the bottom plate 510 and disposed around the rotation axis of the turntable 200, the elastic seats 520 are provided with through holes 521, and the plurality of spray heads 300 are disposed through the corresponding through holes 521. The elastic seat 520 has elasticity, and the turntable 200 can drive the spray head 300 to swing on the elastic seat 520.
It will be appreciated that when the cam 423 is in the first position, the turntable 200 overcomes the elastic force of the elastic seat 520, so that the nozzle is disposed obliquely.

The plurality of elastic seats 520 are correspondingly distributed between two adjacent ribs 630, so that the positions of the gaskets 500 are effectively limited, the tilting of part of the positions of the gaskets 500 is reduced, and the realization of the function of the nozzle 300 needing to swing is not affected.
Referring to fig. 10 and 13, in the embodiment of the present invention, the elastic seat 520 includes a bending portion 522 and a sealing portion 523 connected to each other, the bending portion 522 is disposed around the sealing portion 523, a through hole 521 is formed between the sealing portions 523, and the sealing portion 523 is in sealing engagement with the nozzle 300, thereby preventing water from seeping between the sealing portion 523 and the nozzle 300. The bending part 522 has elasticity and can be deformed to provide a sufficient deformation space for the deflection of the spray head 300, and also provide a restoring force for restoring the spray head 300.

Referring to fig. 11, 12 and 13, in the embodiment of the present invention, the spray head 300 includes a first section 310, a second section 320 and a third section 330 that are sequentially connected, a first arc surface 311 is disposed on an outer wall of the first section 310, a second arc surface 211 is disposed on an inner wall of the installation position 210, and the first arc surface 311 and the second arc surface 211 are both spherical and are in sliding fit. The outer wall of the second section 320 is in interference connection with the inner wall of the via 521, so that the sealing part 523 is in sealing fit with the second section 320, thereby reducing the occurrence of water leakage, water seepage and the like. The outer wall of the third section 330 is provided with a first guiding surface 331, the bottom wall of the lower casing 101 is provided with a water outlet 130, the inner wall of the water outlet 130 is provided with a second guiding surface 131, the first guiding surface 331 and the second guiding surface 131 are spherical, and the first guiding surface 331 and the second guiding surface 131 are in sliding fit, so that the spray head 300 can deflect to change the water outlet direction.
Referring to fig. 6 and 14, in the embodiment of the present invention, the driving assembly 400 further includes a second impeller 430, the first impeller 410 and the second impeller 430 are respectively connected to two ends of the worm 422, and rotation axes of the first impeller 410, the second impeller 430 and the worm 422 are coincident and can rotate synchronously. Two rotating frames 190 are arranged in the mounting cavity 120, the two rotating frames 190 are arranged at intervals, and two ends of the worm 422 are respectively connected with the two rotating frames 190 in a rotating mode.
Referring to fig. 15, the upper casing 102 is further provided with a second water inlet 140, the second water inlet 140 is communicated with the installation cavity 120, the first impeller 410 is disposed at the water outlet end of the first water inlet 110, and the second impeller 430 is disposed at the water outlet end of the second water inlet 140. Namely, the first water inlet 110 can drive the first impeller 410 to rotate when water is fed, and the second water inlet 140 can drive the second impeller 430 to rotate when water is fed. By adopting the scheme of the first impeller 410 and the second impeller 430, the stress at the two ends of the worm 422 can be balanced or nearly balanced, so that the stability of the worm 422 during rotation can be improved. When the water flow drives the first impeller 410 and the second impeller 430 at different positions, different driving forces can be generated, so that the rotating speed of the worm 422 is adjusted, and finally the frequency of water type conversion of the water control valve 1000 is adjusted, thereby meeting the use requirements of different people.
To avoid the situation where the worm 422 is reversed or stalled by the water flow striking the first impeller 410 or the second impeller 430 at different locations, in the embodiment of the present invention, the outer diameter of the first impeller 410 is larger than the outer diameter of the second impeller 430. For example, as shown in fig. 14, the first impeller 410 has an outer diameter R1, the second impeller 430 has an outer diameter R2, and R1 is greater than R2. By designing the outer diameter of the first impeller 410 to be larger than the outer diameter of the second impeller 430, and the flow area of the first water inlet 110 to be equal to or larger than the flow area of the second water inlet 140, the first water inlet 110 always impacts the maximum outer diameter of the first impeller 410 when water is fed, so that the worm 422 can rotate synchronously with the first impeller 410 regardless of the position of the second impeller 430 when water is fed from the second water inlet 140, thereby avoiding the occurrence of reverse rotation or stalling.
Because different people have different requirements on the water type switching frequency of the water control valve 1000, the rotating speed of the worm 422 can be regulated to control the water type switching frequency of the water control valve 1000. For example, referring to fig. 15, on a projection plane perpendicular to the rotation axis of the turntable 200, the rotation center line S1 of the first impeller 410 divides the projection of the housing 100 into a first region 160 and a second region 170. In the first embodiment of the present invention, the center line of the first water inlet 110 and the center line of the second water inlet 140 are located in the first area 160 together, so that the water flowing through the first water inlet 110 is used to drive the first impeller 410 to rotate in the first direction, and the water flowing through the second water inlet 140 is also used to drive the second impeller 430 to rotate in the first direction. The water control valve 1000 further includes a plug 150, where the plug 150 is used to control the flow area of the inlet end of the second water inlet 140, so that the second impeller 430 obtains different impact forces to adjust the rotation speed of the worm 422, and further adjust the frequency of water switching of the water control valve 1000.
In the second embodiment of the present invention, the center line of the first water inlet 110 is located in the first area 160, and the center line of the second water inlet 140 is located in the second area 170, so that the water flowing through the first water inlet 110 is used to drive the first impeller 410 to rotate in the first direction, and the water flowing through the second water inlet 140 is used to drive the second impeller 430 to rotate in the second direction, and the first direction and the second direction are opposite. The choke plug 150 is used for controlling the flow area of the second water inlet 140, so that the second impeller 430 obtains different driving forces to adjust the rotation speed of the worm 422. It should be noted that, the maximum outer diameter of the first impeller 410 is greater than the maximum outer diameter of the second impeller 430, and the maximum through-flow section of the first water inlet 110 is greater than or equal to the maximum through-flow section of the second water inlet 140. The water flowing through the first water inlet 110 may impinge on the largest outer diameter of the first impeller 410, thus ensuring that the worm 422 rotates in the first direction regardless of where the second water inlet 140 impinges on the second impeller 430. And the water flowing through the second water inlet 140 is used for driving the second impeller 430 to rotate along the second direction, and can play a role of the speed reducing worm 422. It should be noted that, in fact, the second impeller 430 still rotates along the first direction under the driving of the first impeller 410, but only has a tendency to rotate toward the second direction under the influence of the water flow of the second water inlet 140, so the function of the speed reducing worm 422 can be achieved.
In the third embodiment of the present invention, the water flowing through the first water inlet 110 is used to drive the first impeller 410 to rotate along the first direction, and the plug 150 can seal a part of the through-flow cross section of the second water inlet 140. When the plug 150 is in the first position, the water flowing through the second water inlet 140 is used to drive the second impeller 430 to rotate along the first direction; when the plug 150 is in the second position, the water flowing through the second water inlet 140 is used to drive the second impeller 430 to rotate in a second direction, which is opposite to the first direction. By changing the position of the plug 150, the water flowing through the second water inlet 140 drives the second impeller 430 to rotate in different directions (only the direction tends to rotate, and the actual rotation direction of the second impeller 430 is the same as the rotation direction of the first impeller 410), so that the rotation speed of the worm 422 is adjusted to change the water type switching frequency of the water control valve 1000.
Referring to fig. 15 and 16, in the fourth embodiment of the present invention, the center line of the first water inlet 110 is located in the first area 160, and the water flow passing through the first water inlet 110 impacts the first impeller 410, so that the first impeller 410 rotates in the first direction, and the projection of the second water inlet 140 spans the first area 160 and the second area 170; the plug 150 is capable of blocking different positions of the second water inlet 140, such as when the plug 150 is in the first position, i.e., the position shown in fig. 15, at which time the water flow through the second water inlet 140 impinges on the second impeller 430, such that the second impeller 430 rotates in the first direction. By changing the position of the plug 150, it is possible to adjust the position of the water flow striking the second impeller 430, for example, to gradually slow down the rotation speed of the worm 422 when the position of the water flow striking the second impeller 430 from the second water inlet 140 approaches the rotation center line S1 of the first impeller 410. When the plug 150 is at the second position, that is, the position shown in fig. 16, the water flow passing through the second water inlet 140 impacts the second impeller 430, so that the second impeller 430 has a tendency to rotate along the second direction, and the rotation speed of the worm 422 can be further slowed down due to the opposite first direction and second direction, so that the water type change frequency of the water control valve 1000 is slowed down, and the water type change frequency of the water control valve 1000 can be changed by adjusting the position of the plug 150, so as to meet the use requirements of different people.
In order to adjust the position of the plug 150, referring to fig. 2, in the embodiment of the present invention, a connection post 2140 is disposed on the top wall of the water passing chamber 2130, the connection post 2140 is fixedly connected to the plug 150, and the plug 150 may be made of rubber or silica gel material, so as to ensure a certain tightness. The side wall of the mounting groove 2110 is provided with one of a sliding fit slider 2111 or a slide groove 2210, for example, a plurality of sliders 2111; the side wall of the face cover 2200 is provided with the other one of the slider 2111 and the slide groove 2210, for example, a plurality of slide grooves 2210. Through the cooperation of the sliding block 2111 and the sliding groove 2210, the user manually rotates the surface cover 2200, and the surface cover 2200 can drive the water control valve 1000 to rotate, so that the plug 150 can seal different positions of the second water inlet 140, and finally the water type switching frequency of the water control valve 1000 can be adjusted.
Referring to fig. 1 and 2, in an embodiment of the present invention, in order to facilitate a user to dial the surface cover 2200, the surface cover 2200 is further provided with a dial button 2220, the dial button 2220 is fixedly connected with the surface cover 2200, and the user can adjust the position of the surface cover 2200 by dialing the position of the dial button 2220, thereby adjusting the water type switching frequency of the water control valve 1000, and satisfying different use requirements of the user.

Because the plurality of spray heads 300 are correspondingly arranged on the plurality of mounting positions 210 of the turntable 200, when the turntable 200 rotates reciprocally, the positions of the spray heads 300 can be driven to change, so that the water outlet direction is changed, for example, when the spray heads 300 are used for discharging water, the water outlet direction can be changed alternately between the water outlet in the vertical direction and the water outlet in the inclined direction. The plurality of mounting locations 210 are disposed around the rotation axis of the turntable 200, so that the plurality of spray heads 300 are also disposed around the rotation axis of the turntable 200, and when the water outlet direction of the spray heads 300 is inclined, the water outlet state of the water control valve 1000 is a weaving water type; when the water outlet direction of the spray head 300 is vertical, the water outlet state of the water control valve 1000 is vertical water type. Through the reciprocal rotation of carousel 200 for water control valve 1000 switches between weaving water type and vertical water type, and visual effect is better, and is pleasing to the eye degree high. Meanwhile, the change of the water outlet direction of the spray head 300 can increase the flushing area of the water control valve 1000 and massage the skin of different positions of a user, so that the massage effect is improved, and the use experience of the user is better.
