[0037] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0038] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0039] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0040] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0041] like Figures 1 to 4As shown, this embodiment of the invention provides a flow regulating valve 1, applied to a shower, for regulating the water flow rate of the shower. The flow regulating valve 1 includes a valve housing 10, a flow regulating assembly, and a motor assembly 20. The valve housing 10 has a first receiving cavity and a second receiving cavity, and an inlet and an outlet connected to the first receiving cavity. The flow regulating assembly includes a fixed plate 31, a movable plate 32, and a rotating shaft 33. The fixed plate 31 is fixedly disposed within the first receiving cavity and located between the inlet and the outlet, and has a water passage hole. The movable plate 32 is disposed within the first receiving cavity and abuts against the fixed plate 31, and the movable plate 32 can rotate relative to the fixed plate 31 and coincide with the water passage hole. The rotating shaft 33 is connected to the movable plate 32, and the rotating shaft 33 can drive the movable plate 32 to rotate to adjust the overlapping area of ​​the movable plate 32 and the water passage hole. The motor assembly 20 is disposed within the second receiving cavity and is configured to drive the rotating shaft to rotate. When the moving plate 32 is completely aligned with the water passage hole (i.e., the overlapping area of ​​the moving plate 32 and the water passage hole is 100%), the water passage hole is completely closed, and the water in the inlet cannot flow through the water passage hole to the outlet. At this time, the water flow rate is 0. When the moving plate 32 is completely offset from the water passage hole (i.e., the overlapping area of ​​the moving plate 32 and the water passage hole is 0%), the water passage hole is completely opened, and the water in the inlet can flow through the water passage hole to the outlet. At this time, the water flow rate is 100%. During the process of the moving plate changing from being completely aligned with the water passage hole to being completely offset from the water passage hole, as the rotation angle of the moving plate 32 increases, the degree to which the water passage hole is opened is greater, and the flow rate of water passing through the water passage hole is greater, that is, the water flow rate is greater. Therefore, by driving the rotating shaft and the moving plate 32 to rotate through the motor assembly 20, the overlapping area of ​​the moving plate 32 and the water passage hole can be adjusted, that is, the opening degree of the water passage hole can be adjusted, thereby adjusting the water flow rate. Moreover, the adjustment method is electronic control adjustment, which has high adjustment accuracy. Furthermore, the motor assembly 20 is integrated inside the valve body 10, making the overall structure more compact and miniaturized.

[0042] In this embodiment, refer to Figure 2 and Figure 3 The motor assembly 20 includes a stator 21 and a rotor 22. The rotor 22 is disposed inside the stator 21 and has a central hole. The rotating shaft 33 passes through the central hole. The rotor 22 can rotate relative to the stator 21 when the stator 21 is energized. A bearing 23 for supporting the rotation of the rotating shaft 33 is disposed inside the housing 21. In other embodiments, the rotor 22 may be disposed outside the stator 21, and this embodiment is not limited thereto. Optionally, the motor assembly 20 is a stepper motor. That is, the stator 21 is provided with multiple sets of coils, which generate a magnetic field when energized. The rotor 22 is composed of multiple sets of strong magnetic components. The rotor 22 and the stator 21 form multiple fixed angles. Each time a pulse current is emitted, the rotor 22 will rotate by a fixed angle, which is the rotation angle of the rotating shaft 33.

[0043] Reference Figures 1 to 3In this embodiment, the flow regulating valve 1 also includes a manual component 100. One end of the rotating shaft 33 extends to the outside of the valve housing 10, and the manual component 100 is connected to the portion of the rotating shaft 33 located outside the valve housing 10. When the stator 21 and / or rotor 22 and / or current supply fails or malfunctions, the rotating shaft 33 can be rotated by manually moving the manual component 100 to ensure smooth flow regulation of the flow regulating valve 1. Through the above configuration, the flow regulating valve 1 integrates electronic and manual regulation, making flow regulation more reliable. For example, the manual component 100 can be a handwheel or a cantilever. In this embodiment, the manual component 100 and the rotating shaft 33 are connected by a spline. Specifically, the outer surface of the rotating shaft 33 is provided with protruding teeth, and the inner surface of the manual component 100 is provided with tooth grooves. The protruding teeth are embedded in the tooth grooves to form a spline connection to transmit torque. In addition, the manual component 100 and the rotating shaft 33 are also fastened by fasteners, such as bolts or screws, making the connection firm and reliable, and easy to disassemble and assemble. Alternatively, the manual component 100 and the rotating shaft 33 can be connected by snap-fit, riveting, or welding.

[0044] In this embodiment, refer to Figure 3 The valve housing 10 is also provided with a sealing hole, which connects the first receiving cavity and the second receiving cavity. The other end of the rotating shaft 33 passes through the sealing hole and extends into the first receiving cavity to connect with the moving plate 32. A sealing ring 50 is provided between the rotating shaft 33 and the inner wall of the sealing hole to prevent water from entering the second receiving cavity containing the motor assembly 20. Optionally, multiple sealing rings 50 can be provided, and the multiple sealing rings 50 can be distributed at intervals along the axial direction of the rotating shaft 33 to enhance the sealing effect. Optionally, a positioning groove 3321 can be formed on the outer peripheral wall of the rotating shaft 33, and part of the sealing ring 50 is positioned in the positioning groove 3321 to prevent the sealing ring 50 from shifting.

[0045] In this embodiment, refer to Figure 2 and Figure 3 The flow control valve 1 also includes a limiting member 70, such as a snap ring. The limiting member 70 is disposed on the rotating shaft 33 and abuts against the end face of the sealing hole near the second receiving cavity. The rotating shaft 33 is a stepped shaft, including a first shaft portion 331, a second shaft portion 332, and a third shaft portion 333 connected in sequence with increasing diameters. The first shaft portion 331 passes through the center hole of the rotor 22. The limiting member 70 is disposed on the first shaft portion 331. The second shaft portion 332 passes through the sealing hole. The third shaft portion 333 extends into the first receiving cavity. The second shaft portion 332 and the third shaft portion 333 form a first shoulder. An annular limiting groove is provided on the end face of the sealing hole near the first receiving cavity. The first shoulder abuts against the bottom of the annular limiting groove. The limiting member 70 and the first shoulder together limit the axial position of the rotating shaft 33.

[0046] In this embodiment, refer to Figure 2 and Figure 3The flow control valve 1 also includes a wear-resistant pad 60, and the rotating shaft 33 further includes a fourth shaft portion 334. The fourth shaft portion 334 is connected to the end of the third shaft portion 333 opposite to the second shaft portion 332. The fourth shaft portion 334 and the third shaft portion 333 form a second shoulder. The wear-resistant pad 60 is disposed between the second shoulder and the end face of the sealing hole near the first receiving cavity. By providing the wear-resistant pad 60, wear on the rotating shaft 33 during rotation can be prevented.

[0047] Reference Figure 2 and Figure 3 One of the rotating shaft 33 and the moving piece 32 is provided with a connecting protrusion 335, and the other is provided with a connecting groove 322. The connecting protrusion 335 is inserted into the connecting groove 322, thereby connecting the rotating shaft 33 and the moving piece 32. In this embodiment, the connecting protrusion 335 is provided at the end of the fourth shaft portion 334 opposite to the third shaft portion 333, and the connecting groove 322 is provided on the moving piece 32. Alternatively, in other embodiments, the connecting protrusion 335 may be provided on the moving piece 32, and the connecting groove 322 may be provided on the rotating shaft 33. Optionally, the cross-sectional shape of the connecting protrusion 335 and the connecting groove 322 is non-circular, for example, it may be polygonal, to improve the stability of the connection between the rotating shaft 33 and the moving piece 32 and prevent relative rotation between the rotating shaft 33 and the moving piece 32. Furthermore, a positioning frame 40 is provided between the rotating shaft 33 and the moving piece 32. The positioning frame 40 is provided with a through hole 41, and the connecting protrusion 335 passes through the through hole 41 and is inserted into the connecting groove 322. By providing the positioning frame 40, the axial position of the moving piece 32 can be restricted, preventing the moving piece 32 from axially shaking.

[0048] In this embodiment, refer to Figure 2 and Figure 3 The inlet is located on the side wall of the valve housing 10, and the end of the valve housing 10 facing away from the manual component 100 is open, forming the outlet. By making one end of the valve housing 10 open, the assembly of the moving plate 32 and the fixed plate 31 can be facilitated. In this embodiment, in order to fix the fixed plate 31, a sealing sleeve 80 is provided at the opening of the second valve housing 10. The sealing sleeve 80 abuts against the fixed plate 31, and the sealing sleeve 80 and the moving plate 32 together limit the axial position of the fixed plate 31. A limit ring 90 is provided on the inner side of the sealing sleeve 80, which is used to position the sealing sleeve 80. In addition, a positioning protrusion 313 is provided on one of the fixed plate 31 and the cavity wall of the first receiving cavity, and a positioning groove is provided on the other. The positioning protrusion 313 is inserted into the positioning groove to limit the rotation of the fixed plate 31. In other embodiments, both the inlet and outlet can be located on the side wall of the valve housing 10.

[0049] In this embodiment, the valve housing 10 includes a first housing 11 and a second housing 12, which are detachably connected. For example, the first housing 11 and the second housing 12 can be connected by bolts or snap-fit. A first receiving cavity and a sealing hole are both provided in the first housing 11, and a second receiving cavity is provided in the second housing 12. With the above arrangement, it is convenient to disassemble and maintain the components inside the valve housing 10.

[0050] In this embodiment, refer to Figure 4 The number of water passage holes is two, namely the first water passage hole 311 and the second water passage hole 312, which are symmetrically distributed at 180 degrees. The moving plate 32 includes two sealing parts 321, namely the first sealing part and the second sealing part, which are symmetrically distributed at 180 degrees. When the moving plate 32 rotates, the first sealing part alternately overlaps with the first water passage hole 311 and the second water passage hole 312, and at the same time, the second sealing part alternately overlaps with the second water passage hole 312 and the first water passage hole 311. Initially (when the moving plate 32 is at 0 degrees), the first sealing part completely overlaps with the first water passage 311, and the second sealing part completely overlaps with the second water passage 312. The flow rates of both the first water passage 311 and the second water passage 312 are 0. As the moving plate 32 rotates from 0 degrees to 90 degrees, the overlapping area of ​​the first sealing part with the first water passage 311 and the second sealing part with the second water passage 312 is adjusted. Furthermore, as the rotation angle of the moving plate 32 increases, the overlapping area of ​​the first sealing part with the first water passage 311 decreases, and the overlapping area of ​​the second sealing part with the second water passage 312 also decreases. As the moving plate 32 rotates from 90 degrees to 180 degrees, the overlapping area of ​​the first sealing part with the second water passage 312 and the second sealing part with the first water passage 311 is adjusted. Furthermore, as the rotation angle of the moving plate 32 increases, the overlapping area of ​​the first sealing part with the first water passage 311 and the second sealing part with the second water passage 312 also decreases. The overlapping area of ​​the two water passage holes 312 increases, and the overlapping area of ​​the second sealing part and the first water passage hole 311 increases. During the rotation of the moving plate 32 from 180 degrees to 270 degrees, the overlapping area of ​​the first sealing part and the second water passage hole 312 is adjusted, and the overlapping area of ​​the second sealing part and the first water passage hole 311 is adjusted. Furthermore, as the rotation angle of the moving plate 32 increases, the overlapping area of ​​the first sealing part and the second water passage hole 312 decreases, and the overlapping area of ​​the second sealing part and the first water passage hole 311 decreases. During the rotation of the moving plate 32 from 270 degrees to 360 degrees, the overlapping area of ​​the first sealing part and the first water passage hole 311 is adjusted, and the overlapping area of ​​the second sealing part and the second water passage hole 312 is adjusted. Furthermore, as the rotation angle of the moving plate 32 increases, the overlapping area of ​​the first sealing part and the first water passage hole 311 increases, and the overlapping area of ​​the second sealing part and the second water passage hole 312 increases. With the above settings, simply rotating the shaft 33 in one direction can adjust the flow rate of the water passage, making the adjustment method simple.

[0051] like Figures 5 to 6 As shown, this embodiment of the invention also provides a shower, including the aforementioned flow regulating valve 1, a shower body 2, and a mixing valve 3. The shower body 2 has a hot water inlet channel 201, a cold water inlet channel 202, a first mixed water outlet channel 203, and a second mixed water outlet channel 204. The hot water inlet channel 201 and the cold water inlet channel 202 are respectively connected to the hot water inlet and the cold water inlet of the mixing valve 3. The mixing valve 3 is used to mix hot and cold water. The mixed water outlet of the mixing valve 3 is connected to the first mixed water outlet channel 203, which is connected to the inlet of the flow regulating valve 1. The outlet of the flow regulating valve 1 is connected to the second mixed water outlet channel 204. The shower body 2 is also provided with multiple water outlets, such as a top spray outlet 2051, a shower head outlet, and a shower tail outlet. The nozzle 2052, lower nozzle 2053, and handheld nozzle 2054, among others, are all connected to the second mixed water outlet 204. A solenoid valve 4 is installed between each of the multiple nozzles and the second mixed water outlet 204. These solenoid valves 4 control the connection between the second mixed water outlet 204 and the multiple nozzles. The stator 21 of the multiple solenoid valves 4 and the flow regulating valve 1 is electrically connected to the controller 5. The controller 5 has a power interface 501 and a control line interface 502. The power interface 501 is connected to a power source, which can be a battery 6 or an external AC power source. The control line interface 502 is electrically connected to a circuit board. The circuit board has a button assembly 7, which is used to select the nozzle and the water flow rate.

[0052] In this embodiment, the manual component 100 is at least partially exposed outside the shower body 2 for ease of operation.
