An actuation unit for actuating the mixing cylinder and a hose are also included. The hose is connected to the outlet connector at a first end and is movably arranged on the housing at a second end. The hose extends through a channel in the mixing cylinder, and the mixing zone is at least partially arranged between the channel and the housing wall. The first inlet connector can be opened and closed by a first valve, and the second inlet connector can be opened and closed by a second valve. The first valve interacts with the actuation unit via a first actuation end, and the second valve interacts with the actuation unit via a second actuation end. The actuation unit is arranged adjacent to the mixing cylinder, and the valves are mechanically actuated by the actuation unit.

[0073] Example

[0074] Please refer to Figures 1 to 9 A water circuit control device for kitchen and bathroom applications includes a main body 1 and a control mechanism A. The main body 1 has a water circuit section 11. The control mechanism A includes a drive mechanism 2, a valve core 3, and an elastic body 4. The drive mechanism 2 includes a handle unit rotatably connected to the main body 1. The handle unit includes an outer rotating member and an inner driving member. The outer rotating member is an outer rotating ring 21. The inner driving member includes an inner driving ring 22 and a bushing 23. The outer rotating ring 21 is coaxially sleeved outside the inner driving ring 22 and fixed by spokes. The bushing 23 is coaxially rotatably sleeved inside the inner driving ring 22. The bushing 23 has a first end face arranged in a ring shape around the rotation axis. The first end face has a slope 231 with a varying height along the rotation axis. The slope 231, if centered on the center... The arrangement is smooth and varied. The bushing and the inner drive ring are provided with a protrusion that forms a spline and a spline hole to achieve synchronous rotation. The valve core 3 is slidably connected to the main body 1 and the sliding direction is parallel to the rotation axis. The slope 231 abuts against the valve core 3 and drives the valve core 3 to slide. The valve core 3 cooperates with the water circuit 11 and controls the water circuit 11 through the sliding of the valve core 3. The control includes switching, flow regulation, and switching and flow regulation to achieve water temperature regulation. The elastic body 4, such as a spring, is installed between the valve core 3 and the main body 1 and drives the valve core 3 to slide and reset.

[0075] The water circuit section 11 includes a first water circuit 111, a second water circuit 112, and a mixing water circuit 113. Both the first water circuit 111 and the second water circuit 112 are equipped with the aforementioned control mechanism A, and the control mechanisms A of the first water circuit 111 and the second water circuit 112 are arranged symmetrically relative to the rotation axis. The valve cores 3 of the control mechanisms A of the first water circuit 111 and the second water circuit 112 are both aligned with the aforementioned slope 231. Since the slope 231 is centrally symmetrically arranged and smoothly changes, the sliding directions of the valve cores 3 of the control mechanisms of the first water circuit 111 and the second water circuit 112 are reversed during the rotation of the handle unit. This causes the flow rate of the first water circuit 111 to increase, while the flow rate of the second water circuit 112 decreases, and vice versa, thereby achieving water temperature regulation. Figure 3 It is in a completely cold state. Figure 4 It is in a fully heated state. Figure 5 It is a mixture of hot and cold states and can be temperature-adjusted as needed.

[0076] The main body 1 includes an outer shell and an inner shaft. The inner shaft is fixed inside the outer shell, and the outer rotating ring 21 is connected to the outer shell. The inner drive component is rotatably sleeved on the outside of the inner shaft, which not only provides guidance for rotation but also, due to the small outer diameter of the inner drive seat driving the rotation, results in a small friction area, low friction, low operating force, and easy control. A first limiting structure restricting axial movement is provided between the outer shell and the outer rotating ring 21, and a second limiting structure restricting axial movement of the bushing 23 from the first end to the second end is provided between the inner shaft and the bushing 23.

[0077] The main body 1 includes a main body 12, an outer sleeve 13, an upper shell 14, and a water outlet shaft 15. The bottom surface of the main body 12 is recessed to form a control cavity 16. The control cavity 16 has a water outlet 161 perpendicular to the rotation axis. A valve seat 162 is installed at the opening of the control cavity 16. The valve seat 162 has an extension portion located within the control cavity 16. The bottom surface of the valve seat 162 is recessed with a mounting groove. The extension portion penetrates the mounting groove to connect to the water inlet 163 of the control cavity. The control cavity 16 has a control port located between the water inlet and the water outlet, which is formed by a conical wall. The valve core 3 has a control part 34 located within the control cavity 16 and a valve stem 31 fixed to the control part. The end of the valve stem 31 mates with a slope. The control unit 34 is equipped with a sealing element 32. The control unit 34 slides to control the sealing element 32 to seal or open the control port. In the specific structure, the control unit 34 has a large diameter section, a small diameter section, and a conical section between the large diameter section and the small diameter section. The bottom surface of the control unit 34 is recessed with an installation cavity. The elastic body 4 is installed in the installation cavity and abuts against the valve seat 162. The small diameter section is provided with a through groove 33 that connects to the installation cavity. The conical section and the conical wall cooperate to form a control port and can be adjusted from the maximum to the minimum (water shut-off) by sliding to control the water flow area. The sealing element 32 is located between the conical section and the large diameter section. The water inlet pipe 164 is installed at the installation groove. The water flow from the water inlet pipe 164 can enter the annular gap between the control cavity 16 and the large diameter section through the installation groove and the water inlet 163, and pass through the control port from bottom to top to the water outlet 163. The main body 12 is equipped with a mixing port that connects to the outlets of the first and second water passages. The outlet shaft 15 is connected to the mixing port, and the mixing passage 113 includes the mixing port and the outlet shaft 15. Because of the through groove 33, pressure relief and stabilization are achieved, reducing the pressure difference in the water chambers during the up-and-down movement of the valve core and improving control reliability and stability.

The water outlet shaft 15 constitutes the aforementioned inner shaft portion and has a protruding shoulder 151. The second end face of the bushing 23 abuts against the shoulder 151. The shoulder 151 and the bushing 23 abut against each other to form a second limiting structure.

[0079] The aforementioned water control device for kitchen and bathroom applications is used in faucet devices. The upper shell 14 can be configured as the faucet body, which has a water outlet connected to the water outlet shaft 15. As needed, the faucet body is equipped with a sensing mechanism, which has a signal line connected to a control valve 5 located inside the faucet body and controlling the on / off state of the water outlet and the water outlet shaft. A lead wire sheath 121 is also fixed outside the body 12. The lead wire sheath is located inside the outer shell 13, and a through hole is formed between the lead wire sheath and the body to allow the signal wire to pass through and protect the signal wire.

[0080] As needed, a temperature-regulating valve core can be installed, which includes the aforementioned main body, bushing, valve core, and elastomer. These components can be assembled together to form a modular product, such as... Figures 7 to 9 It can be directly installed and adapted to different types of temperature-controlled faucets, with fewer parts, fewer malfunctions, and convenient maintenance.

[0081] In this embodiment, the valve core slides up and down, and its direction can also be adjusted to be tilted or arranged laterally as needed. Example

[0082] Please refer to Figures 10 to 15 The difference between this and Embodiment 1 is that the inner drive component does not include the bushing 23 but includes the inner drive ring 22 and the inner drive ring 22 is directly provided with the first end face, and the first end face is provided with the slope 231; the inner drive ring and the outer rotating part are integrally formed.

[0083] The water circuit includes a control chamber 16, which has an inlet 161 and an outlet 163 spaced apart along a direction parallel to the rotation axis. The control unit 34 slides to control the sealing member 32, which is located between the inlet 161 and the outlet 163 or outside the inlet 161 and the outlet 163. The control unit 34 and the inner wall of the control chamber 16 have a water passage gap, namely the control port of Embodiment 1, and the water volume is adjusted by sliding the control unit 34 to control the change of the area of ​​the water passage gap.

[0084] The main body 1 includes a lower body 171, an upper body 172, a housing 181, a top cover 182, and a water outlet shaft 15. The lower body 171 and the upper body 172 are fixed together and form the control cavity 16 therebetween. The lower body 171 is provided with the water inlet, and the upper body 172 is provided with the water outlet. The lower body and the upper body are fixed inside the housing 181. The water outlet shaft 15 is fixed to the upper body and connected to the water outlet. The top cover is fixed outside the water outlet shaft, and the top cover and the housing are arranged vertically at intervals. The outer rotating ring 21 is adapted to be located between the upper and lower intervals of the top cover and the housing. The upper body 171 has a circumferential wall 173 protruding from its top surface. The water outlet shaft is inserted into the circumferential wall, and the inner drive component is rotatably sleeved on the outside of the circumferential wall. The circumferential wall and the water outlet shaft together form the inner shaft part. The upper body 171 has multiple circumferentially spaced arc walls 174 protruding from its top surface. The upper end of the arc wall is snapped and fixed together with the top cover. The multiple arc walls are arranged circumferentially to surround the circumferential wall. The outer rotating ring 21 is sleeved on the outside of the arc wall, and the spokes pass through the gap between two adjacent arc walls to improve rotational stability.

[0085] The waterway section includes a first waterway 111, which includes the aforementioned control chamber 16. The control mechanism is connected to the first waterway 111 and controls the on / off state and / or flow rate adjustment of the first waterway. Example

[0086] Please refer to Figure 16 , Figure 17 The difference between this embodiment and embodiment 2 is that the water circuit includes a first water circuit 11, a second water circuit 12 and a mixing water circuit. The control mechanism is connected to the first water circuit, and the mixing water circuit is connected to the first water circuit and the second water circuit. The flow rate of the second water circuit is constant, but the water temperature and flow rate can be adjusted by controlling the flow rate of the first water circuit.
