Description

Technical Field

[0001] This invention relates to the field of bathroom product technology, and in particular to a valve and water outlet device. Background Technology

[0002] Existing technology includes devices that store a desired substance. Fluid passing through this device mixes with the stored substance, resulting in water flowing out containing the substance. For example, there are beauty showerheads on the market that store a skin-beautifying agent rich in collagen, which is then present in the water. In some usage scenarios, users desire a high water flow rate and a low consumption rate of the skin-beautifying agent to conserve it. However, the consumption rate of the skin-beautifying agent in beauty showerheads is closely related to the water pressure or flow rate; the higher the water flow, the higher the consumption rate. This makes existing beauty showerheads insufficient to meet user needs. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a valve that can adjust the consumption rate of a substance to be mixed (e.g., a skin care agent), and the consumption rate of the substance to be mixed can increase or decrease synchronously with the total water output of the valve.

[0004] The present invention also provides a water outlet device including the above-mentioned valve.

[0005] A valve according to a first aspect of the present invention includes: a housing having an inlet, an outlet, a main channel, and a storage chamber, wherein the inlet is connected to the main channel, and the storage chamber is used to store a substance to be mixed; a valve core assembly including a stationary plate and a first movable plate, wherein the stationary plate includes a second water passage and a first water passage, the inlet, the main channel, the second water passage, and the outlet are sequentially connected, the first movable plate having a first control port, wherein when the first water passage is connected to the first control port, the inlet, the main channel, the storage chamber, the first water passage, the first control port, and the outlet are sequentially connected; the first control port includes a first water passage area, the first water passage area is connected to the first water passage, and the first movable plate is movable relative to the stationary plate to change the size of the first water passage area.

[0006] The valve according to the first aspect of the present invention has at least the following beneficial effects: if the flow rate of water flowing along the second path is denoted as Q2, the flow rate of water flowing along the first path is denoted as Q1, and the total water output of the valve (the flow rate of water flowing out of the outlet) is denoted as Q... 总 So Q 总= Q2 + Q1. The water flowing along the first path contains the substance to be mixed, and the larger Q1 is, the higher the consumption rate of the substance to be mixed. Since the size of the first water passage area can change with the movement of the first moving plate, Q1 can be adjusted by moving the first moving plate relative to the stationary plate. Since Q1 can be adjusted, the consumption rate of the substance to be mixed stored in the storage chamber can be adjusted. Furthermore, since there are two paths for water to flow in the valve, the first path and the second path, even if Q is increased... 总 The user can also adjust the state of the first moving plate to decrease Q1, and correspondingly, Q2 will increase. Therefore, for the valve of the present invention, the consumption rate of the substance to be mixed does not need to increase or decrease synchronously with the total water output of the valve, which allows the user to flexibly adjust the consumption rate of the substance to be mixed.

[0047] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0048] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, 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 limiting this invention.

[0049] In the description of this invention, "multiple" refers to two or more. 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.

[0050] 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.

[0051] Figure 1 A valve 100 according to an embodiment of the present invention is shown. Figure 2 for Figure 1 The exploded view of valve 100 is shown. Figure 2As shown, the valve 100 includes a housing 101, which has an inlet 201, an outlet 202, and a main channel 203. Figure 8 for Figure 1 The sectional view of valve 100 shown is as follows: Figure 8 As shown, the outer casing 101 also includes a storage chamber 204 for storing the substance to be mixed. The substance to be mixed is not shown in the accompanying drawings. The substance to be mixed can be a skin-beautifying agent containing collagen, or other substances that need to be mixed with the fluid in the main flow channel 203. For example, the substance to be mixed can also be a scale inhibitor, a bactericide, etc. The substance to be mixed stored in the storage chamber 204 can be a liquid, a solid, or a gas.

[0052] The following description uses a skin-beautifying agent as the substance to be mixed, but in other embodiments, the skin-beautifying agent may be replaced with other types of substances to be mixed. Furthermore, although the following description uses water as the fluid flowing into and out of valve 100, and some structural features of the valve 100 of the present invention contain the word "water," the valve 100 of the present invention is not limited to controlling the flow of water; the water flowing into and out of valve 100 may be replaced with gas or other liquids besides water.

[0053] Figure 3 for Figure 2 An exploded view of the valve core assembly 106, as shown below. Figure 2 and Figure 3 As shown, valve 100 includes valve core assembly 106, which includes a stationary plate 302 and a first moving plate 304. Figure 4 As shown, the stationary plate 302 is provided with a second water inlet 406 and a first water inlet 404, which are distributed alternately. Figure 5 As shown, the first moving piece 304 is provided with a first control port 410.

[0054] The inlet 201, main channel 203, second outlet 406, and outlet 202 are "capable" of being connected in sequence. This sequential connection means that the four are connected in sequence when the valve 100 is in certain states (i.e., the examples described below); in other embodiments, this sequential connection also means that the four are connected in sequence regardless of the valve 100's state. Furthermore, when the first outlet 404 is connected to the first control port 410, the inlet 201, main channel 203, storage chamber 204, first outlet 404, first control port 410, and outlet 202 are connected in sequence.

[0055] In this embodiment, the first moving piece 304 is able to rotate relative to the stationary piece 302. Figure 7 The process of the first moving plate 304 rotating relative to the stationary plate 302 is shown. Figure 7 Not a sectional view. Figure 7 The static plate 302 and the first moving plate 304 are provided with cross-sectional lines only for easy distinction between them. The first control port 410 includes a first water-passing area, which is connected to the first water-passing port 404. The first water-passing area is also the area of ​​the first control port 410 that is not blocked by the static plate 302. Figure 7 As shown, the size of the first water-passing area can change as the first moving plate 304 rotates relative to the stationary plate 302. The larger the first water-passing area, the greater the flow rate of water passing through the first water inlet 404 and the first control port 410.

[0056] In other embodiments, the first movable piece 304 may also move relative to the stationary piece 302, as long as the movement of the first movable piece 304 can cause the size of the first water-passing area.

[0057] Figure 8 This is a cross-sectional view of valve 100 in its first state. Figure 9 A cross-sectional view of valve 100 in its second state is shown. Figure 8 In the middle, valve 100 is completely closed, and water cannot flow out from outlet 202. And... Figure 9 In this configuration, the inlet 201, main channel 203, second overflow 406, and outlet 202 are sequentially connected. At this time, a portion of the water entering the main channel 203 from the inlet 201 can subsequently flow sequentially through the second overflow 406, the second control port 407, and the outlet 202. Furthermore, Figure 9 In this configuration, the first water inlet 404 is connected to the first control port 410, and the water inlet 201, main channel 203, storage chamber, first water inlet 404, first control port 410, and water outlet 202 are also connected in sequence. At this time, a portion of the water entering the channel from the water inlet 201 can subsequently flow through the storage chamber 204, the first water inlet 404, the first control port 410, and the water outlet 202 in sequence.

[0058] When valve 100 is in the second state, for water entering the flow channel from inlet 201, a portion of the water flows out from outlet 202 without passing through storage chamber 204. The flow path of this portion of water is as follows: Figure 9 The second path 502 is shown; another part of the water first flows through the storage chamber 204 and then flows out from the outlet 202, and the flow path of this part of the water is as follows. Figure 9 The first path 501 is shown. The water flowing along the first path 501 contains a skin-beautifying agent. If the flow rate of the water flowing along the second path 502 is denoted as Q2, and the flow rate of the water flowing along the first path 501 is denoted as Q1, then the total outflow from valve 100 (the flow rate of water flowing out of outlet 202) is called Q. 总 So Q 总 =Q2+Q1.

[0059] Since the size of the first water-passing area can change with the movement of the first moving plate 304, the movement of the first moving plate 304 relative to the stationary plate 302 can adjust Q1. Because Q1 is adjustable, the consumption rate of the skin-beautifying agent stored in the storage chamber 204 can be adjusted. Since the valve has two paths for water flow, the first path 501 and the second path 502, even if Q is increased... 总 The user can also adjust the state of the first moving plate 304 to decrease Q1, and correspondingly, Q2 will increase. Therefore, for the valve 100 of the present invention, the consumption rate of the skin care agent can increase or decrease in sync with the total water output of the valve 100, which allows the user to flexibly adjust the consumption rate of the skin care agent.

[0060] like Figure 3 As shown, in one embodiment, the valve core assembly 106 further includes a second movable plate 303. Both the second movable plate 303 and the first movable plate 304 are capable of moving relative to the stationary plate 302, and the movement of the second movable plate 303 is independent of the movement of the first movable plate 304. "The movement of the second movable plate 303 is independent of the movement of the first movable plate 304" means that when the second movable plate 303 moves relative to the stationary plate 302, the first movable plate 304 may not move synchronously with the second movable plate 303. It should be noted that in some embodiments, the movement of the second movable plate 303 and the first movable plate 304 can be manually driven; in other embodiments, the movement of the second movable plate 303 and the first movable plate 304 can also be driven by a power source such as a motor.

[0061] like Figure 5 As shown, the second movable piece 303 is provided with a second control port 407. For example... Figure 9 As shown, when the second water outlet 406 is connected to the second control port 407, the water inlet 201, the main channel 203, the second water outlet 406, the second control port 407 and the water outlet 202 are connected in sequence, so that the water flows along the second path 502.

[0062] Figure 6 The process of the second moving plate 303 rotating relative to the stationary plate 302 is shown. Figure 6 Not a sectional view. Figure 6 The static plate 302 has a cross-sectional line simply to easily distinguish between the static plate 302 and the second moving plate 303. The second control port 407 includes a second water passage area, which communicates with the second water inlet 406. The second water passage area is the area of ​​the second control port 407 that is not blocked by the static plate 302. Figure 6As shown, as the second moving plate 303 rotates counterclockwise relative to the stationary plate 302, the second water-passing area gradually increases. Conversely, if the second moving plate 303 rotates clockwise relative to the stationary plate 302, the second water-passing area gradually decreases. The larger the second water-passing area, the greater the flow rate of water passing through the second water inlet 406 and the second control port 407.

[0063] Since the size of the second water passage area can change with the movement of the second moving plate 303, Q2 can be adjusted by moving the second moving plate 303 relative to the stationary plate 302. Therefore, setting the second moving plate 303 helps to improve the adjustment flexibility of the water flow of the valve 100.

[0064] like Figure 8 As shown, the outer casing 101 also includes a chamber inlet 205 and a chamber outlet 206, both of which are connected to the storage chamber 204. The chamber outlet 206 is connected to the first water inlet 404. The valve 100 also includes a check valve unit 105, which is installed at the chamber inlet 205. The check valve unit 105 is configured to: connect the chamber inlet 205 to the main flow channel 203 when the first water inlet 404 is connected to the first control port 410; and separate the chamber inlet 205 from the main flow channel 203 when the first water inlet 404 and the first control port 410 are separated. "Separated" means not connected. The separation of the first water inlet 404 and the first control port 410 means that the first moving plate 304 completely covers and blocks the first water inlet 404.

[0065] If the user does not need to use water containing skin care products, the user can adjust the position of the first moving plate 304 to separate the first water outlet 404 and the first control port 410. Since the valve 100 is equipped with a check valve 105, when the user does not need to use water containing skin care products, the check valve 105 can prevent the skin care products in the storage chamber 204 from leaking into the main channel 203, thus reducing the waste of skin care products.

[0066] The structure of the anti-reverse unit 105 is as follows: Figure 8 As shown, the anti-reverse unit 105 includes a fixed member 602, a movable member 603, and an elastic member 604. The fixed member 602 is connected to the outer casing 101 and has an anti-reverse channel 601 extending through both ends. One end (top) of the anti-reverse channel 601 communicates with the chamber inlet 205. The movable member 603 is movably connected to the fixed member 602 and can switch between an open position and a closed position relative to the fixed member 602. Figure 8 As shown, when the movable part 603 is in the closed position, the movable part 603 abuts against the bottom end of the fixed part 602 to block the anti-reverse passage 601. Figure 9As shown, when the movable part 603 is in the open position, there is a gap between the bottom end of the movable part 603 and the fixed part 602. The movable part 603 releases the blockage of the check channel 601, and the main channel 203 and the chamber inlet 205 are connected through the check channel 601. One end of the elastic part 604 is connected to the movable part 603, and the other end of the elastic part 604 is connected to the fixed part 602. The elastic force of the elastic part 604 is used to keep the movable part 603 in place. Figure 8 The closed position is shown. For example, the elastic member 604 is in a compressed state, with its top end abutting against the fixed member 602 and its bottom end abutting against the piston member. The elastic member 604 is used to drive the movable member 603 to move downward. In other embodiments, the top end of the elastic member 604 may also be connected to the housing.

[0067] The working principle of the anti-reverse unit 105 is as follows. Figure 8 As shown, when the first moving plate 304 completely covers and blocks the first water outlet 404, the chamber outlet 206 is also effectively blocked. The skin-beautifying agent and air in the storage chamber 204 cannot leave the storage chamber 204 through the chamber outlet 206. The chamber outlet 206 cannot act as a pressure relief port for the storage chamber 204, and the pressure in the storage chamber 204 remains at a high level. The sum of the pressure in the storage chamber 204 and the elastic force of the elastic member 604 is greater than the water pressure in the main channel 203. Therefore, the water in the main channel 203 cannot easily push away the moving member 603, and the moving member 603 remains in the closed position. Figure 9 As shown, when the first water outlet 404 and the first control port 410 are connected, the chamber outlet 206 can serve as the pressure relief port of the storage chamber 204. The water in the pressure main channel 203 in the storage chamber 204 can push open the movable part 603 and enter the storage chamber 204.

[0068] like Figure 8 As shown, the outer casing 101 is also provided with a feeding port 207, which communicates with the storage chamber 204. Figure 2 As shown, valve 100 also includes a plug 104, which is detachably connected to housing 101 and seals the feed port 207. The plug 104 prevents the skin care agent in storage chamber 204 and water flowing through storage chamber 204 from leaking from the feed port 207. When the skin care agent stored in valve 100 is insufficient, the user can remove the plug 104 and then inject the skin care agent into storage chamber 204 through feed port 207. The plug 104 and housing 101 can be connected by a threaded connection. In other embodiments, the plug 104 can also be inserted into feed port 207 with an interference fit.

[0069] like Figure 6As shown on the right end, the second movable piece 303 can cover and block the second water inlet 406, at which point the area of ​​the second water inlet is 0. For example... Figure 7 As shown on the right end, the first moving plate 304 can cover and block the first water inlet 404, at which point the area of ​​the first water passage is 0. The above configuration helps to improve the functionality of the valve 100.

[0070] Specifically, such as Figure 10 As shown, valve 100 also has a third state. When valve 100 is in the third state, the first moving plate 304 completely covers the first water inlet 404, the first water inlet 404 and the first control port 410 are not connected, and the first water inlet 404 is blocked by the first moving plate 304; and at this time, the second water inlet 406 is connected to the second control port 407. In this case, Q1 = 0, Q 总 =Q2, the water flowing from valve 100 does not contain skin-beautifying agents. When valve 100 is in the third state, the second moving plate 303 moves relative to the stationary plate 302, thus adjusting Q. 总 In certain usage scenarios, if the user does not need to use water containing skin care products, the user can switch valve 100 to the third state to reduce waste of skin care products.

[0071] like Figure 11 As shown, valve 100 also has a fourth state. When valve 100 is in the fourth state, the second moving plate 303 completely covers the second water inlet 406, the second water inlet 406 is not connected to the second control port 407, and the second water inlet 406 is blocked by the second moving plate 303; and at this time, the first water inlet 404 is connected to the first control port 410. In this case, Q2 = 0, Q 总 =Q1. At this time, by moving the first moving plate 304 relative to the stationary plate 302, Q can be adjusted. 总 This regulates the rate at which the skin-beautifying agent is consumed.

[0072] When valve 100 is in the fourth state, the consumption rate of the skin-beautifying agent increases or decreases synchronously with the total water output of valve 100. However, it should be noted that, in addition to the fourth state, valve 100 of the present invention also has a second state. In the second state, the consumption rate of the skin-beautifying agent may not increase or decrease synchronously with the total water output of valve 100, providing greater flexibility in adjusting the consumption rate. Moreover, valve 100 of the present invention employs different methods for adjusting the skin-beautifying agent consumption rate in the second and fourth states, respectively.

[0073] In addition, such as Figure 8As shown, when valve 100 is in the first state, the second moving plate 303 completely covers the second water outlet 406, and the second water outlet 406 is blocked by the second moving plate 303. Furthermore, the first moving plate 304 completely covers the first water outlet 404, and the first water outlet 404 is blocked by the first moving plate 304. When valve 100 is in the first state, valve 100 is completely closed, and no water flows out of the outlet 202 of valve 100.

[0074] It should be noted that, as Figure 8 As shown, the valve core seat 301 of the valve core assembly 106 includes a second clearance port 208 and a first clearance port 209, the outer shell 101 includes a third clearance port 210, the chamber outlet 206 is connected to the first water inlet 404 through the second clearance port 208, and the third clearance port 210, the first clearance port 209 and the second water inlet 406 are connected sequentially from bottom to top.

[0075] The structure of the stationary plate 302, the second moving plate 303, and the first moving plate 304 will be described below.

[0076] like Figure 5 As shown, the stationary plate 302 includes a main body portion 401 and a central portion 402 fixedly connected to each other. The main body portion 401 and the central portion 402 can be integrally formed or separately disposed. The main body portion 401 is circular and has a central through hole 403 and a second water inlet 406, which are spaced apart. The central portion 402 is connected to the wall of the central through hole 403, and the side of the central portion 402 and the wall of the central hole together define a first water inlet 404. A portion of the central portion 402 protrudes relative to the axial end face of the main body portion 401. The second water inlet 406 is fan-shaped, and the first water inlet 404 is fan-shaped. A fan-shaped ring (annular sector) refers to the shape obtained by cutting a circular ring into a fan shape.

[0077] The second movable piece 303 is generally circular. The second movable piece 303 is stacked on top of the main body 401. The second movable piece 303 has a mounting through hole 408, which is spaced apart from a second control port 407, which is located around the periphery of the mounting through hole 408. A portion of the central part 402 passes through the mounting through hole 408. The mounting through hole 408 is a circular hole, and the outer circumferential surface of the central part 402 includes two arc surfaces, allowing the central part 402 to rotate within the mounting through hole 408. In this way, the second movable piece 303 can rotate relative to the stationary piece 302. Furthermore, with the above arrangement, the central part 402 can position the second movable piece 303, facilitating the assembly between the second movable piece 303 and the stationary piece 302.

[0078] The first movable piece 304 is approximately circular. The top surface of the central portion 402 is flush with the top surface of the second movable piece 303. The outer diameter of the first movable piece 304 is larger than the outer diameter of the mounting through hole 408. A portion of the first movable piece 304 is stacked with the central portion 402, and another portion of the first movable piece 304 is stacked with the second movable piece 303. In this way, the first control port 410 can communicate with the first water inlet 404 through the mounting through hole 408.

[0079] like Figure 5 As shown, to match the shape of the second water inlet 406, the second control port 407 is also configured as a fan-shaped ring. To ensure that the second moving plate 303 can completely cover the second water inlet 406, the central angle between the second water inlet 406 and the second control port 407 can be less than 180°. To match the shape of the first water inlet 404 and enhance the continuity of Q1 adjustment, the first control port 410 on the first moving plate 304 is also fan-shaped.

[0080] In other embodiments, the second water inlet 406 and the second control port 407 may both be configured in a fan shape. The first water inlet 404 and the first control port 410 may both be configured in a fan-shaped annular shape.

[0081] like Figure 5 As shown, the outer edge of the stationary plate 302 has a stationary plate notch 405, the outer edge of the second moving plate 303 has a second notch 409, and the outer edge of the first moving plate 304 has a first notch 411. The purpose of the above notches will be introduced later. In addition, the top surface of the first moving plate 304 has a water passage groove 412, which is open at both ends and extends radially along the first moving plate 304. The top of the second control port 407 is located on the bottom wall of the water passage groove 412. This arrangement can prevent the valve stem 305 (which will be introduced later) from completely blocking the first control port 410.

[0082] like Figure 11 As shown, valve 100 also includes a second adjusting member 102 and a first adjusting member 103. The second adjusting member 102 is fixed relative to the second movable plate 303, and is movably connected to the housing 101, with at least a portion of the second adjusting member 102 exposed outside the housing 101. The first adjusting member 103 is fixed relative to the first movable plate 304, and is movably connected to the housing 101, with at least a portion of the first adjusting member 103 exposed outside the housing 101.

[0083] "The second adjusting member 102 and the second movable piece 303 are relatively fixed" can mean that the second adjusting member 102 and the second movable piece 303 are directly connected and fixed to each other, or that the second adjusting member 102 and the second movable piece 303 are indirectly connected together through some intermediate components. The relative fixing of the second adjusting member 102 and the second movable piece 303 means that the second adjusting member 102 and the second movable piece 303 can move synchronously. Since at least a portion of the second adjusting member 102 is exposed outside the housing 101, the second adjusting member 102 can come into contact with the user's hand. The user can drive the second adjusting member 102 to move, thereby driving the second movable piece 303 to move, and thus adjusting Q2.

[0084] Similarly, the fact that the first adjusting member 103 and the first moving piece 304 are relatively fixed means that the first adjusting member 103 and the first moving piece 304 can move synchronously. The part of the first adjusting member 103 exposed outside the housing 101 can be in contact with the user's hand. The user can drive the first adjusting member 103 to move with his hand, thereby driving the first moving piece 304 to move, and thus adjusting Q1.

[0085] With the second adjusting member 102 and the first adjusting member 103 provided, the movement of the second moving plate 303 and the first moving plate 304 is mainly driven by human power. The valve 100 does not need to be provided with a separate power source (such as a motor) to drive the movement of the second moving plate 303 and the first moving plate 304, and the cost of the valve 100 is low.

[0086] If the second movable piece 303 needs to rotate relative to the stationary piece 302, then the second adjusting member 102 can be configured to rotate relative to the outer casing 101. The user can twist the second adjusting member 102 to rotate the second movable piece 303. If the second movable piece 303 needs to move relative to the stationary piece 302, then the second adjusting member 102 can be configured to move relative to the outer casing 101. The user can drive the second adjusting member 102 to move by pressing, pushing, pulling, etc., thereby moving the second movable piece 303. Similarly, if the first movable piece 304 needs to rotate relative to the stationary piece 302, then the first adjusting member 103 can be configured to rotate relative to the outer casing 101; if the first movable piece 304 needs to move relative to the stationary piece 302, then the first adjusting member 103 can be configured to move relative to the outer casing 101.

[0087] like Figure 11As shown, when both the second adjusting member 102 and the first adjusting member 103 are rotatable relative to the housing 101, the rotation axis of the second adjusting member 102 and the rotation axis of the first adjusting member 103 are collinear, and the second adjusting member 102 and the first adjusting member 103 are distributed along the axial direction of the second adjusting member 102. This arrangement helps to reduce the distance between the second adjusting member 102 and the first adjusting member 103, making it convenient for the user to adjust the angles of different moving plates sequentially. In addition, this arrangement also helps to improve the structural compactness of the valve 100.

[0088] The other components in the valve core assembly 106 will be introduced below.

[0089] Please refer to Figure 17 The valve core assembly 106 also includes a valve stem sleeve 308, which is fixedly connected to the second adjusting member 102. A portion of the valve stem sleeve 308 is disposed in the second notch 409, thereby achieving fixation between the valve stem sleeve 308 and the second moving plate 303. The second notch 409 is not located in... Figure 17 As shown in Figure 5 As shown in the figure, Figure 5 As shown, the second notch 409 is located at the outer edge of the second movable piece 303. When the second adjusting member 102 is turned by the user, the valve stem sleeve 308 rotates synchronously with the second adjusting member 102, and the valve stem sleeve 308 abuts against the wall of the second notch 409, thereby pushing the second movable piece 303 to rotate. In this way, the synchronous rotation of the second adjusting member 102 and the second movable piece 303 can be achieved.

[0090] Similarly, please refer to Figure 17 The valve core assembly 106 also includes a valve stem 305, which is fixedly connected to the first adjusting member 103. A portion of the valve stem 305 is disposed in the first notch 411, thereby achieving fixation between the valve stem 305 and the first moving plate 304. The first notch 411 is not in Figure 17 As shown in Figure 5 As shown, the first notch 411 is located at the outer edge of the first movable piece 304. When the first adjusting member 103 is turned by the user, the valve stem 305 rotates synchronously with the first adjusting member 103. The valve stem 305 abuts against the wall of the first notch 411, thereby pushing the first movable piece 304 to rotate. In this way, the synchronous rotation of the first adjusting member 103 and the first movable piece 304 can be achieved.

[0091] like Figure 14 As shown, the valve stem sleeve 308 includes a second seat portion 707, a cylindrical portion 709, and a second protrusion 708. The second protrusion 708 and the cylindrical portion 709 are respectively connected to the opposite sides of the second seat portion 707. The valve stem sleeve 308 is integrally formed. Figure 14As shown, the outer circumferential surface of the cylindrical portion 709 has multiple external teeth, and the second adjusting member 102 has multiple internal teeth. The second adjusting member 102 is fitted onto the outside of the cylindrical portion 709, and the external and internal teeth mesh with each other. In this way, the second adjusting member 102 and the cylindrical portion 709 can rotate synchronously. In other embodiments, the cylindrical portion 709 and the second adjusting member 102 can also be connected by threaded fasteners, or they can be connected by adhesive bonding. A portion of the second protrusion 708 is inserted into the second notch 409.

[0092] like Figure 13 As shown, the valve stem 305 includes a first seat portion 704, a stem portion 706, and a first protrusion 705. The valve stem 305 is a one-piece structure. The stem portion 706 and the first protrusion 705 are respectively connected to opposite sides of the first seat portion 704. The stem portion 706 is fixedly connected to the first adjusting member 103. The stem portion 706 and the first adjusting member 103 can also be connected by the meshing of external and internal teeth. A portion of the first protrusion 705 is inserted into the first notch 411.

[0093] like Figure 11 As shown, the cylindrical portion 709 is hollow, and the stem portion 706 and a portion of the first adjusting member 103 are rotatably disposed inside the cylindrical portion 709. The valve 100 also includes a screw 108 and a decorative cap 109. The screw 108 connects the first adjusting member 103 and the stem portion 706 together, causing the first adjusting member 103 to press against the top surface of the second adjusting member 102, thereby preventing the second adjusting member 102 from disengaging from the valve stem sleeve 308. The decorative cap 109 is detachably connected to the first adjusting member 103, and the decorative cap 109 covers the screw 108, thereby improving the aesthetics of the valve 100.

[0094] like Figure 18 As shown, the valve core seat 301 and the valve core cover 309 are interlocked, and the wear-resistant ring 307 is sandwiched between the valve core cover 309 and the second seat body 707. Figure 11 As shown, the gland 107 is threadedly connected to the housing 101, and the bottom surface of the gland 107 abuts against the top surface of the valve core cover 309 to prevent the valve core assembly 106 and the housing 101 from separating from each other.

[0095] In one embodiment, the valve core assembly 106 further includes a valve core sleeve 306, which guides and limits the rotation of the second moving plate 303. Figure 12 As shown, the valve core sleeve 306 is provided with a second limiting groove 701, which is fan-shaped. Please refer to... Figure 15 and Figure 16A portion of the second protrusion 708 of the valve stem sleeve 308 is disposed in the second limiting groove 701. When the valve stem sleeve 308 and the second moving plate 303 rotate synchronously, the second protrusion 708 moves along the second limiting groove 701. The walls at both ends of the second limiting groove 701 can abut against the second protrusion 708, thereby limiting the rotation of the valve stem sleeve 308, and further limiting the rotation of the second moving plate 303.

[0096] like Figure 12 As shown, in one embodiment, the valve core sleeve 306 is further provided with a first limiting groove 702, which guides and limits the rotation of the first moving plate 304. Figure 13 As shown, a portion of the first protrusion 705 protrudes relative to the outer peripheral surface of the first base portion 704. For example... Figure 16 As shown, this protruding portion can be disposed in the first limiting groove 702, which is fan-shaped. When the valve stem 305 and the first moving plate 304 rotate synchronously, the first protrusion 705 moves along the first limiting groove 702. The walls at both ends of the first limiting groove 702 can abut against the first protrusion 705, thereby limiting the rotation of the valve stem 305 and, consequently, limiting the rotation of the first moving plate 304.

[0097] like Figure 19 As shown, the valve core seat 301 also includes a third protrusion 710. A portion of the third protrusion 710 is disposed in the third notch 703 of the valve core seat 301 to prevent the valve core sleeve 306 from rotating relative to the valve core seat 301. Another portion of the third protrusion 710 is disposed in the stationary plate notch 405 to prevent the stationary plate 302 from rotating relative to the valve core seat 301. Furthermore, the valve core seat 301 and the housing 101 are also fixed to each other. Figure 17 As shown, the valve core seat 301 has a side opening 211 on its side. Water flowing out from the second control port 407 or the first control port 410 will subsequently pass through the second limiting groove 701 and the side opening 211 in sequence, and finally flow to the outlet 202.

[0098] The present invention also provides a water outlet device, which includes the valve 100 in any of the above embodiments. Specifically, the water outlet device can be a shower head, faucet, etc. When the skin-beautifying agent is used as the substance to be mixed and the water outlet device is set as a shower head, the water outlet device can function as a skin-beautifying shower head. The valve 100 can be installed inside the housing of the water outlet device; in other embodiments, the valve 100 can also be installed outside the housing of the water outlet device.

[0099] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
