[0002] Existing water dispensing devices generally have on / off functions, while some only have a metered dispensing function. Since the flow rate of metered dispensing is fixed, it's difficult to meet user needs in different usage scenarios, resulting in poor versatility and impacting user experience and satisfaction. Furthermore, when dispensing metered water, it's difficult to reset to the initial position after mode switching, making operation complex and inconvenient. Summary of the Invention

[0091] Example 1

[0092] This embodiment provides a water outlet control mechanism suitable for water outlet scenarios such as bathrooms, water dispensers, and beverage machines. Figures 1-2 As shown, the water outlet control mechanism includes a main body 1 and a water outlet control structure 2. The main body 1 is similar in shape to a cylindrical or cuboid structure. A cavity is provided inside the main body 1. The main body 1 is provided with an inlet 11 and an outlet 12. The water outlet control structure 2 is at least partially disposed in the cavity of the main body 1. The water outlet control structure 2 is configured to move relative to the main body 1, so that the inlet 11 and the outlet 12 are selectively connected, and switch between a quantitative water outlet mode and a non-quantitative water outlet mode.

[0093] The inlet 11 is used to introduce water, and the outlet 12 is used to discharge water. Water enters the inner cavity of the main body 1 through the inlet 11 and is finally discharged from the outlet 12. The water specifically refers to water before or after treatment, such as spray water, purified water, beverage water, or wastewater. The inlet 11 is located at one end of the main body 1 along the axial direction, and the outlet 12 is located on the side wall of the main body 1 along the radial direction. The axial directions of the inlet 11 and the outlet 12 are perpendicular to each other. Of course, in some other embodiments, the inlet 11 and the outlet 12 can also be located at both ends of the main body 1 along the axial direction. This embodiment does not limit the location of the inlet 11 and the outlet 12, and can be adjusted according to actual production needs.

[0094] When the inlet 11 and outlet 12 are not connected, the water outlet control mechanism is in the water shut-off mode; when the inlet 11 and outlet 12 are connected, the water outlet control mechanism is in the water outlet mode, which has a quantitative water outlet mode and a non-quantitative water outlet mode.

[0095] Specifically, the quantitative water discharge mode means that even if water is continuously supplied from the inlet 11, the flow rate or volume of water discharged from the outlet 12 is a constant value; the non-quantitative water discharge mode means that if water is continuously supplied from the inlet 11, the flow rate or volume of water discharged from the outlet 12 is not a constant value, but varies with the water supply from the inlet 11.

[0096] The water outlet control mechanism provided in this embodiment can freely switch between quantitative and non-quantitative water outlet modes using the water outlet control structure 2. This makes mode switching convenient for users and improves the user experience. Meanwhile, the main body 1 is equipped with an inlet 11 and an outlet 12. The water circuits for both quantitative and non-quantitative water outlet modes can share the same inlet 11 and outlet 12, eliminating the need for additional inlets 11 or outlets 12 and saving manufacturing costs.

[0097] In one embodiment, the water outlet control structure 2 has a first station and a second station. When the water outlet control structure 2 is located at the first station, the inlet 11 and the outlet 12 are not connected. When the water outlet control structure 2 is located at the second station, the water outlet control structure 2 is in a quantitative water outlet mode and / or a non-quantitative water outlet mode.

[0098] Understandably, the first station corresponds to a closed outlet 12, meaning no water can be discharged. The second station corresponds to an open outlet 12, meaning water can be discharged. Under this condition, a further distinction can be made between quantitative and non-quantitative water discharge modes. Specifically, at the second station, the water discharge control structure 2 can be in either quantitative or non-quantitative water discharge mode. This can be achieved by cooperating with other structures within the water discharge control mechanism to differentiate between quantitative and non-quantitative water discharge modes, avoiding interference between them. Furthermore, the water discharge control structure 2 itself can be further refined to divide the station into different intervals, each corresponding to a specific quantitative or non-quantitative water discharge mode.

[0099] The first and second workstations are arranged circumferentially along the main body 1. The water outlet control structure 2 is configured to rotate relative to the main body 1 for switching between the first and second workstations. By rotating the water outlet control structure 2, the switching between the first and second workstations can be achieved, making it convenient for users to operate.

[0100] In one embodiment, the second station includes a first substation and a second substation. When the water outlet control structure 2 is located at the first substation, the water outlet control structure 2 is in a quantitative water outlet mode. When the water outlet control structure 2 is located at the second substation, the water outlet control structure 2 is in a non-quantitative water outlet mode.

[0101] The first substation and the second substation are respectively located on both sides of the first substation along the circumferential direction of the main body 1. The water outlet control structure 2 is configured to rotate relative to the main body 1 for switching between the first substation and the second substation.

[0102] In this way, the two substations correspond to the quantitative water dispensing mode and the non-quantitative water dispensing mode respectively. By rotating the water dispensing control structure 2, the switching between the two substations can be realized, thereby realizing the switching between the quantitative water dispensing mode and the non-quantitative water dispensing mode. The operation is convenient for users.

[0103] In one embodiment, such as Figure 2 As shown, the water outlet control mechanism also includes an inner shell 4, which is at least partially disposed within the cavity of the main body 1. The water outlet control structure 2 passes through the inner shell 4. The inner shell 4 is used to protect the water outlet control structure 2, and the water outlet control structure 2 can realize the switching of the water path within the inner shell 4.

[0104] For example, such as Figure 2 As shown, the inner shell 4 includes a shell 41, a bottom cover 42, and a top cover 43. The bottom cover 42 and the shell 41 are disposed inside the main body 1. The bottom cover 42 and the top cover 43 are respectively disposed at both ends of the shell 41 along the axial direction of the main body 1. One end of the top cover 43 abuts against the end face of the shell 41, and a clamping member 44 is disposed on the outside of the other end. The clamping member 44 is specifically a pressure cap nut, which is sleeved on the outside of the top cover 43 to lock the shell 41 and the top cover 43. The bottom cover 42 is disposed at the end of the main body 1 near the water inlet 11 and is disposed corresponding to the water inlet 11. The outer wall of the bottom cover 42 is not attached to the inner wall of the main body 1, but a gap is provided between the bottom cover 42 and the inner wall of the main body 1. The gap communicates with the water inlet 11 and the water outlet 12 respectively, so as to transport the water flowing in from the water inlet 11 to the water outlet 12 through the gap.

[0105] Specifically, such as Figures 2-4As shown, a first water inlet hole 421 is provided at the end of the bottom cover 42 facing the water inlet 11. The first water inlet hole 421 extends through the bottom cover 42 along the axial direction of the main body 1. A pilot hole 420 is provided at the end of the bottom cover 42 away from the water inlet 11. A first water outlet hole 422 is provided on the peripheral side wall of the bottom cover 42. The axial directions of the first water inlet hole 421 and the first water outlet hole 422 are perpendicular to each other. The first water inlet hole 421 is connected to the first water outlet hole 422 through the pilot hole 420. Water flowing in from the water inlet 11 flows through the first water inlet hole 421 to the pilot hole 420, and then flows out through the first water outlet hole 422 into the gap between the bottom cover 42 and the inner wall of the main body 1.

[0106] Specifically, such as Figure 2 and Figure 5 As shown, the periphery of the housing 41 is provided with a second water inlet 411 and a second water outlet 412 at intervals. The second water inlet 411 and the second water outlet 412 are arranged in upper and lower layers. The second water inlet 411 is located near the water inlet 11 and communicates with the first water outlet 422. The second water outlet 412 is correspondingly arranged with the water outlet 12 and communicates with each other. Water in the gap is introduced into the inner cavity of the housing 41 through the second water inlet 411. The water outlet control structure 2 controls the water path switching in the housing 41, so that water is delivered to the water outlet 12 through the second water outlet 412 and discharged.

[0107] In one embodiment, such as Figures 2-7 As shown, the water outlet control mechanism also includes a pilot control structure 5, which is located inside the inner shell 4 and between the water inlet 11 and the water outlet control structure 2. The pilot control structure 5 is used to selectively block the pilot hole 420.

[0108] When the pilot control structure 5 is blocked at the pilot hole 420, the water outlet control mechanism is in the closed mode; when the pilot control structure 5 is offset from the pilot hole 420, the water outlet control mechanism is in the water outlet mode, i.e., a quantitative water outlet mode or a non-quantitative water outlet mode. Since the pilot control structure 5 is located between the inlet 11 and the water outlet control structure 2, the pilot control structure 5 can control the water path before the water outlet control structure 2, realizing the pilot function, improving the accuracy of control, and to a certain extent reducing the risk of leakage in the closed mode.

[0109] Specifically, such as Figure 2 , Figure 6 and Figure 7As shown, the pilot control structure 5 includes a pilot seat 51 and a pilot valve 52. The pilot seat 51 is disposed between the housing 41 and the bottom cover 42. The pilot seat 51 is made of elastic material and can also be called a cup seat. The pilot valve 52 is also made of elastic material and can be called a cup. The pilot valve 52 is disposed within the pilot seat 51 and slides in cooperation with the pilot seat 51. The pilot valve 52 is used to selectively block the pilot hole 420. A guide post protrudes from the side of the pilot seat 51 facing the pilot valve 52. The guide post passes through the pilot valve 52 and the pilot hole 420. The pilot valve 52 can slide along the axial direction of the guide post, providing a guiding fit and preventing large positional displacement of the pilot valve 52 during movement.

[0110] In one embodiment, such as Figure 2 , Figure 6 and Figure 7 As shown, the water outlet control structure 2 includes a first control component 21 and a second control component 22. The first control component is disposed within the main body 1, and a pressure relief hole 511 is provided within the main body 1. The pressure relief hole 511 is specifically disposed on the pilot seat 51 within the main body 1, and is located between the inlet 11 and the outlet 12. The second control component 22 is at least partially disposed within the main body 1 and abuts against the first control component 21.

[0111] The second control component 22 is configured to rotate relative to the main body 1 and drive the first control component 21 to move along the axial direction of the main body 1, so that the first control component 21 controls the end away from the second control component 22 to selectively block the pressure relief hole 511.

[0112] When the first control component 21 and the pressure relief hole 511 are misaligned and the pressure relief hole 511 is not blocked, the water flowing out from the pilot hole 420 can enter the pilot seat 51, then flow through the pressure relief hole 511 into the housing 41, and finally be discharged from the outlet 12 through the second water outlet hole 412. The water outlet control mechanism is in the water outlet mode, that is, the quantitative water outlet mode or the non-quantitative water outlet mode.

[0113] When the first control component 21 is blocked by the pressure relief hole 511, since the pressure relief hole 511 is located between the water inlet 11 and the water outlet 12, it is equivalent to cutting off the water path between the water inlet 11 and the water outlet 12. That is, the water flowing out from the pilot hole 420 cannot enter the housing 41 through the pilot seat 51, and is in the water shut-off mode, or used to end the quantitative water output mode, so as to more accurately control the water output of the quantitative water output mode.

[0114] As the second control component 22 rotates, the first control component 21 can convert the rotation of the second control component 22 into movement along the axial direction of the main body 1, thereby realizing the switching of water outlet mode (quantitative water outlet mode and non-quantitative water outlet mode) and water shut-off mode, making it convenient for users to operate.

[0115] In one embodiment, such as Figure 2 , Figure 6 and Figure 7 As shown, the first control component 21 includes a push rod 211, one end of which abuts against the second control component 22, and the other end is provided with a control end 212. The control end 212 is used to control the opening and closing of the pressure relief hole 511. The push rod 211 and the control end 212 can be a separate structure, which facilitates the replacement and maintenance of the control end 212 for long-term use. Alternatively, the push rod 211 and the control end 212 can be an integrally formed structure, which reduces the parts assembly process and saves production costs.

[0116] Specifically, the control end 212 includes a first end 2121 and a second end 2122 coaxially arranged. The outer diameter of the first end 2121 is smaller than the outer diameter of the second end 2122. The first end 2121 passes through the pressure relief hole 511 and is clearance-fitted with the pressure relief hole 511. The second end 2122 passes through the pressure relief hole 511 and is interference-fitted with the pressure relief hole 511.

[0117] like Figure 2 As shown, when the first end 2121 is located inside the pressure relief hole 511, due to the clearance fit between the first end 2121 and the pressure relief hole 511, there is a gap between the first end 2121 and the inner wall of the pressure relief hole 511. Water in the pilot control structure 5 can enter the inner shell 4 through the gap to realize the quantitative water output mode and the non-quantitative water output mode.

[0118] like Figure 8 As shown, when the second end 2122 is located inside the pressure relief hole 511, due to the interference fit between the second end 2122 and the pressure relief hole 511, the second end 2122 and the inner wall of the pressure relief hole 511 are tightly fitted, and the water in the pilot control structure 5 cannot enter the inner shell 4 through the gap, thus realizing the water shut-off mode.

[0119] Under the control of the second control component 22, the push rod 211 can switch modes by moving up and down along the axial direction of the main body 1, which is convenient to operate and use.

[0120] It is understandable that the number of the first end 2121 and the second end 2122 can be one, meaning that the push rod 211 has only one corresponding water outlet mode position or one corresponding water shut-off mode position during movement; the number of at least one of the first end 2121 and the second end 2122 can be multiple, corresponding to multiple water outlet mode positions or water shut-off mode positions. For example, as Figure 9As shown, there are two first ends 2121. The two first ends 2121 are set at both ends of the second end 2122 along the axial direction of the main body 1. The outer diameter of the end of the control end 212 near the pressure relief hole 511 forms a small, large, and small structure, which can correspond to the two different water discharge modes of quantitative water discharge mode and non-quantitative water discharge mode, respectively.

[0121] like Figures 2-9 As shown, the first control component 21 also includes a first reset member 213, which may specifically be a spring. The first reset member 213 is sleeved on the outside of the push rod 211 for resetting the push rod 211. In this way, as the second control component 22 controls the push rod 211 to move along the axial direction of the main body 1 and toward the inlet 11, the push rod 211 compresses the first reset member 213, which is in a gradually compressed state. Under its own restoring force, the compressed first reset member 213 has a tendency to rebound, thereby driving the push rod 211 to reset, ensuring the continuity and reliability of the next mode switching.

[0122] In one embodiment, the first control component 21 further includes a stop 214, which is disposed within the housing 41 of the main body 1. The stop 214 has a first guide hole, through which the push rod 211 passes and can slide relative to it. The first guide hole serves as a guide. Simultaneously, both ends of the first reset member 213 abut against the pilot seat 51 of the guide control structure and the stop 214 or the inner wall of the housing 41, respectively. The stop 214 or the housing 41 provides a support position for the first reset member 213, facilitating its reset function.

[0123] In one embodiment, the first control component 21 further includes a first seal 215, which is disposed in the pressure relief hole 511. When the second end 2122 of the push rod 211 passes through the pressure relief hole 511, the second end 2122 can fit tightly with the first seal 215, thereby improving the sealing effect, preventing the risk of water leakage in the water-off mode, and improving the sealing effect of the water-off mode.

[0124] In one embodiment, such as Figure 2 , Figures 11-13As shown, the second control component 22 includes a guide member 221, which can be referred to as a guide wheel or a non-standard wheel. The guide member 221 abuts against the push rod 211. A first guide rail 2211 and a second guide rail 2212 are provided on the side of the guide member 221 facing the first control component 21. The push rod 211 can move along the first guide rail 2211 and the second guide rail 2212. The two guide rails of the guide member 221 provide a planned path for the push rod 211, allowing the push rod 211 to have different height positions. The first guide rail 2211 corresponds to the first workstation, and the second guide rail 2212 corresponds to the second workstation.

[0125] For example, a groove is provided on the side of the guide member 221 facing the water inlet 11, with the groove opening facing the water inlet 11. The bottom of the groove can form at least one of the first guide rail 2211 and the second guide rail 2212. The shape of the groove can be regular or irregular. One of the first guide rail 2211 and the second guide rail 2212 can also be the end face of the guide member 221 facing the water inlet 11. In this embodiment, the setting position and shape of the first guide rail 2211 and the second guide rail 2212 are not limited. As long as there is a difference in the height position of the two guide rails along the axial direction of the main body 1, that is, the distance between the two guide rails and the pressure relief hole 511 is different, under the guidance of the two guide rails, the movement displacement of the push rod 211 along the axial direction of the main body 1 is different, resulting in the control end 212 of the push rod 211 passing through the pressure relief hole 511 at different positions, which can realize the switching between the water outlet mode and the water shut-off mode.

[0126] In one embodiment, the second control component 22 further includes a rotary rod 222, which passes through the guide member 221. The rotary rod 222 drives the guide member 221 to rotate relative to the main body 1, so that the top rod 211 can move along the first guide rail 2211 and the second guide rail 2212 for switching between the water outlet mode and the water shut-off mode.

[0127] In actual use, the user can operate the screw to rotate the lever 222, which drives the guide 221 to rotate. Under the elastic force of the first reset member 213, the push rod 211 tightly abuts against the guide 221. As the guide 221 rotates, it guides the push rod 211 to move along the first guide track 2211 and the second guide track 2212, facilitating mode switching. The first guide track 2211 corresponds to the first station, where the inlet 11 and outlet 12 are not connected and are in the water shut-off mode. The second guide track 2212 corresponds to the second station, where the water outlet control structure 2 is in the water outlet mode, i.e., the quantitative water outlet mode and / or the non-quantitative water outlet mode.

[0128] In one embodiment, the first guide rail 2211 and the second guide rail 2212 are a continuous structure disposed on the guide member 221. This method ensures that there are no interruptions during mode switching, guaranteeing the continuity of mode switching and thus ensuring the smoothness and convenience of the switching operation.

[0129] Specifically, the central angle of the first guide rail 2211 is smaller than the central angle of the second guide rail 2212; wherein, when the rotary rod 222 abuts against the first guide rail 2211, the water outlet control structure 2 is in the water shut-off mode; when the rotary rod 222 abuts against the second guide rail 2212, the water outlet control structure 2 is in the quantitative water outlet mode and / or the non-quantitative water outlet mode.

[0130] In this approach, since the first guide rail 2211 corresponds to the water shut-off mode, its central angle is relatively small, thus not wasting space occupied by the guide component 221, and also shortening the water shut-off time, resulting in timely water shut-off and a faster response speed. Since the second guide rail 2212 corresponds to the water dispensing mode, its central angle is relatively large, fully utilizing the space occupied by the guide component 221, increasing the coverage area of ​​the second guide rail 2212 on the guide component 221, ensuring the required time for the water dispensing mode, and improving the accuracy of water dispensing.

[0131] In one embodiment, such as Figure 2 , Figures 11-13 As shown, the second guide rail 2212 includes a first sub-rail 22121 and a second sub-rail 22122. The first sub-rail 22121 and the second sub-rail 22122 are disposed on both sides of the first guide rail 2211 along the circumferential direction of the main body 1. The first sub-rail 22121 and the second sub-rail 22122 are a continuous structure disposed on the guide member 221. The central angle of the first sub-rail 22121 is larger than the central angle of the second sub-rail 22122.

[0132] Among them, such as Figure 10 As shown, when the rotary rod 222 abuts against the second sub-track 22122, the water outlet control structure 2 is in a non-quantitative water outlet mode. Figure 11 As shown, when the rotary rod 222 abuts against the first guide rail 2211, the water outlet control structure 2 is in the water shut-off mode. Figure 12 As shown, when the rotary rod 222 abuts against the first sub-track 22121, the water outlet control structure 2 is in the quantitative water outlet mode;

[0133] In this manner, since the first sub-track 22121 corresponds to the quantitative water dispensing mode, the movement of the push rod 211 along the first sub-track 22121 corresponds to the quantitative water dispensing process of the water outlet 12. The central angle of the first guide track 2211 is relatively large, fully occupying the space of the guide member 221, increasing the coverage area of ​​the first guide track 2211 on the guide member 221, ensuring the time required for the quantitative water dispensing mode, and improving the accuracy of water dispensing. Since the second sub-track 22122 corresponds to the non-quantitative water dispensing mode, the central angle of the second sub-track 22122 is relatively small. When the second end 2122 of the push rod 211 passes through the pressure relief hole 511, continuous water dispensing can be achieved, without wasting the coverage area occupied by the second sub-track 22122 on the guide member 221.

[0134] Specifically, the distance between the first sub-track 22121 and the inlet 11 is less than the distance between the second sub-track 22122 and the inlet 11.

[0135] Since the control end 212 of the push rod 211 has a first end 2121 and two second ends 2122, the two second ends 2122 are set at both ends of the first end 2121, that is, along the axial direction of the main body 1 and towards the water inlet 11. The first end 2121, the second end 2122 and the first end 2121 are arranged in sequence. The second sub-track 22122, the first guide track 2211 and the first sub-track 22121 are arranged in sequence and connected to each other. When the push rod 211 abuts against the second sub-track 22122 with the highest height, the push rod 211 is at the highest position of movement. Then the first end 2121 at the lowest end of the push rod 211 passes through the pressure relief hole 511. Water can be transported to the inner shell 4 through the pressure relief hole 511 to realize the non-quantitative water output mode. When the top rod 211 abuts against the first guide rail 2211 at the middle height position, the top rod 211 tends to descend. The second end 2122, located in the middle of the top rod 211, passes through the pressure relief hole 511, sealing the pressure relief hole 511. Water cannot be delivered to the inner shell 4 through the pressure relief hole 511, thus achieving the water shut-off mode. When the top rod 211 abuts against the first sub-rail 22121 at the lowest height position, the top rod 211 tends to continue descending. The first end 2121, located at the uppermost end of the top rod 211, passes through the pressure relief hole 511, allowing water to be delivered to the inner shell 4 through the pressure relief hole 511. The central angle of the first sub-rail 22121 is relatively large. When the rotation angle of the guide member 221 is exactly the same as the central angle of the first sub-rail 22121, the quantitative water dispensing mode ends.

[0136] It should be noted that the second sub-track 22122, the first guide track 2211, and the first sub-track 22121 need to meet different height positions, center angles, etc. on the guide member 221. For example, a groove is provided on the side of the guide member 221 facing the inlet 11. The bottom wall of the groove has a gradient structure, one side wall of the groove has a straight arm structure, and the other side wall has a slope structure. This slope structure connects the bottom wall of the groove and the end face of the guide member 221. Then, the second sub-track 22122 actually corresponds to the area near the straight wall of the groove, the first guide track 2211 actually corresponds to the area near the slope structure of the groove, and the first sub-track 22121 corresponds to the end face of the guide member 221 facing the inlet 11.

[0137] In one embodiment, such as Figures 2-12 As shown, the water outlet control structure 2 also includes a reset component 23. The reset component 23 is disposed inside the main body 1 and between the first control component 21 and the second control component 22. The reset component 23 can drive the second control component 22 to rotate relative to the main body 1 for resetting the second control component 22.

[0138] Driven by the reset component 23, the second control component 22 can be rotated and reset, ensuring the accuracy and reliability of the water output in the quantitative water output mode.

[0139] Specifically, the reset assembly 23 includes an impeller assembly 231 and a reduction gear assembly 232. The reduction gear assembly 232 is disposed between the impeller assembly 231 and the second control assembly 22. The impeller assembly 231 can drive the second control assembly 22 to rotate through the reduction gear assembly 232.

[0140] Under water pressure, the impeller assembly 231 rotates counterclockwise relative to the main body 1. The impeller 2312 drives the reduction gear assembly 232 to rotate, which reduces the water flow speed and prevents the water output time in the quantitative water output mode from being too short. The reduction gear assembly 232 drives the second control component 22 to rotate counterclockwise. During the rotation of the guide member 221, the push rod 211 moves slowly upward along the first sub-track 22121 to the first guide track 2211 under the elastic restoring force of the first reset member 213, corresponding to the closed position. The second end 2122 is sealed in the pressure relief hole 511, stopping the water output.

[0141] Specifically, such as Figures 2-12As shown, the impeller assembly 231 includes an impeller housing 2311 and an impeller 2312. The impeller 2312 is disposed within the impeller housing 2311, which provides support for the impeller 2312. A stop block 214 is disposed on either the impeller housing 2311 or the impeller 2312, providing a support position for the stop block 214. A second guide hole is also provided on the impeller housing 2311. A push rod 211 passes through the second guide hole and slides within it, serving a guiding function and improving the alignment accuracy of the push rod 211 and the pressure relief hole 511.

[0142] Specifically, such as Figures 2-12 As shown, the gear set includes a first gear 2321, a second gear 2322, a third gear 2323, and a fourth gear 2324. The output end of the impeller assembly 231 is connected to the first gear 2321. The first gear 2321 meshes with the second gear 2322, the second gear 2322 meshes with the third gear 2323, and the third gear 2323 meshes with the fourth gear 2324. The fourth gear 2324 is connected to the guide member 221 of the second control component 22. It can be understood that the number of gears in the reduction gear set 232 is not limited, that is, it can be a multi-stage transmission, and the number of second gears 2322 and third gears 2323 can be one or more. The guide shaft passes through multiple second gears 2322 or multiple third gears 2323 to form different gear combinations.

[0143] In one embodiment, such as Figure 10 As shown, the water outlet control mechanism also includes a limiting structure 3, which is disposed between the reset component 23 and the first control component 21. The limiting structure 3 is used to limit the distance between the first control component 21 and the reset component 23, and to lock the water outlet control structure 2 in the non-quantitative water outlet mode.

[0144] For example, a limiting block 31 is provided on the top rod 211 of the first control component 21, and a raised rib 32 is provided on the impeller 2312. Two adjacent raised ribs 32 form a limiting groove. When the top rod 211 is at the highest position, the limiting block 31 and the raised rib 32 are at the same height. The limiting block 31 prevents the impeller 2312 from rotating, so the guide 221 will not rotate, and the top rod 211 cannot be reset, thus ensuring the stability of the non-quantitative water output mode.

[0145] In one embodiment, such as Figure 2 , Figures 14-15 As shown, the water outlet control structure 2 also includes a damper 24, which is disposed between the second control component 22 and the reset component 23, so that the rotational force of the reset component 23 can be transmitted unidirectionally to the second control component 22 through the damper 24.

[0146] In this way, when the user mode is switched by rotating the rotary lever 222, the rotary lever 222 will drive the guide 221 to rotate, but will not drive the reduction gear set 232 and the impeller set 231 to rotate. However, in the quantitative mode, as the water pressure increases, the rotational force of the reset component 23 can be transmitted unidirectionally to the second control component 22 through the damper 24 for the reset of the guide 221 and for the shutdown of the quantitative water output mode.

[0147] In one embodiment, the damper 24 includes a pad 241 and a second reset member 242. The second reset member 242, the pad 241 and the reset assembly 23 are stacked together. The second control assembly 22 passes through the pad 241 and the second reset member 242 and abuts against the second reset member 242.

[0148] The second reset element 242 can be a disc spring, and the washer 241 can be a wear-resistant washer. The rotating rod 222 and the fourth gear 2324 are rotatable but have mutual friction. The second reset element 242 and the wear-resistant washer 241 are placed between the rotating rod 222 and the fourth gear 2324, and the second reset element 242 is fixed and compressed using a stainless steel block 240 and the shoulder of the rotating rod 222. When the rotating rod 222 switches to the quantitative water dispensing mode, the rotating rod 222 rotates. Because the fourth gear 2324 meshes with other gears in the reduction gear set 232, the fourth gear 2324 cannot rotate under the action of the reduction gear set 232, and the rotating rod 222 rotates over the friction between itself and the fourth gear 2324. In the quantitative water dispensing mode, the impeller set 231 drives the reduction gear set 232 to rotate. As the fourth gear 2324 rotates, it drives the guide element 221 and the rotating rod 222 to reset under the action of friction.

[0149] In one embodiment, such as Figure 2 , Figure 6 and Figure 7 As shown, the second control component 22 also includes a handle 223, a retaining ring 224, and a sealing ring 225. The rotating rod 222 passes through the handle 223 and is fixed by a nut 226, allowing the user to easily operate and rotate the rotating rod 222. The retaining ring 224 is sleeved on the outside of the rotating rod 222 and positioned between the rotating rod 222 and the top cover 43, used for resetting the rotating rod 222. The sealing ring 225 is sleeved on the outside of the rotating rod 222 and positioned between the rotating rod 222 and the top cover 43, used to ensure a tight seal between the top cover 43 and the rotating rod 222.

[0150] In one embodiment, the static friction between the second control component 22 and the second reset component 242 is greater than the resistance friction between the second control component 22 and the body 1.

[0151] That is, the static friction between the shoulder of the rotary rod 222 and the second reset member 242 needs to be greater than the friction between the rotary rod 222 and the end cover, sealing ring 225, snap ring 224, etc. Using this static friction, the reset assembly 23 drives the rotary rod 222 and the guide member 221 to reset through the gasket 241 and the second reset member 242. Moreover, when switching modes, the rotary rod 222 will not carry the second reset member 242, ensuring the reliability of mode switching.

[0152] This embodiment also provides a water outlet device, including the aforementioned water outlet control mechanism. The water outlet control structure 2 allows for free switching between a quantitative water outlet mode and a non-quantitative water outlet mode, making mode switching convenient for users and improving user experience. Simultaneously, the main body 1 is provided with an inlet 11 and an outlet 12. The water circuits for both quantitative and non-quantitative water outlet modes can share the same inlet 11 and outlet 12, eliminating the need for additional inlets 11 or outlets 12 and saving manufacturing costs.

[0153] This embodiment also provides a water outlet control mechanism, such as... Figures 1-15 As shown, the water outlet control mechanism includes a main body 1 and a water outlet control structure 2. The main body 1 is provided with an inlet 11 and an outlet 12. The water outlet control structure 2 is at least partially disposed within the main body 1. The water outlet control structure 2 includes a first control component 21, a second control component 22, a reset component 23, and a damper 24. The second control component 22 is configured to rotate relative to the main body 1 and drive the first control component 21 to move along the axial direction of the main body 1, so that the inlet 11 and the outlet 12 are selectively connected for the opening and closing of the quantitative water outlet mode. The reset component 23 is disposed between the first control component 21 and the second control component 22. The reset component 23 can drive the second control component 22 to rotate relative to the main body 1 for the reset of the second control component 22. The damper 24 is disposed between the second control component 22 and the reset component 23, so that the rotational force of the reset component 23 can be transmitted unidirectionally to the second control component 22 through the damper 24.

[0154] When the second control component 22 rotates relative to the main body 1 and drives the first control component 21 to move along the axial direction of the main body 1, the inlet 11 and the outlet 12 are not connected. That is, the first control component 21 and the pressure relief hole 511 are misaligned and the pressure relief hole 511 is not blocked. Water flowing out from the pilot hole 420 can enter the pilot seat 51, then flow through the pressure relief hole 511 into the housing 41, and finally be discharged from the outlet 12 through the second outlet hole 412. The water outlet control mechanism is in the water outlet state of the quantitative water outlet mode.

[0155] When the second control component 22 rotates relative to the main body 1 and drives the first control component 21 to move along the axial direction of the main body 1, the inlet 11 and the outlet 12 are connected to each other. That is, the first control component 21 blocks the pressure relief hole 511. Since the pressure relief hole 511 is located between the inlet 11 and the outlet 12, it is equivalent to cutting off the water path between the inlet 11 and the outlet 12. That is, the water flowing out from the pilot hole 420 cannot enter the housing 41 through the pilot seat 51, and it is in the water shut-off mode, or used to end the quantitative water output mode, so as to more accurately control the water output of the quantitative water output mode.

[0156] The reset component 23 can drive the second control component 22 to rotate relative to the main body 1. Under the drive of the reset component 23, the second control component 22 can be rotated and reset, ensuring the accuracy and reliability of the water output in the quantitative water output mode.

[0157] The rotational force of the reset assembly 23 can be transmitted unidirectionally to the second control assembly 22 through the damper 24. In this way, when the user mode is switched by rotating the rotary lever 222, the rotary lever 222 will drive the guide 221 to rotate, but will not drive the reduction gear set 232 and the impeller set 231 to rotate. However, in the quantitative mode, as the water pressure increases, the rotational force of the reset assembly 23 can be transmitted unidirectionally to the second control assembly 22 through the damper 24 for the reset of the guide 221 and for the shutdown of the quantitative water output mode.

[0158] Example 2

[0159] This embodiment is similar to Embodiment 1, with the only difference being the specific structural details of the control terminal 212, guide member 221, and damper 24.

[0160] like Figures 16-21 As shown, the control end 212 of the rotary rod 222 provided in this embodiment includes a first end 2121 and a second end 2122. There is one first end 2121 and one second end 2122. The first end 2121 passes through the pressure relief hole 511 and is clearance-fitted with the pressure relief hole 511. The second end 2122 passes through the pressure relief hole 511 and is interference-fitted with the pressure relief hole 511.

[0161] The guide member 221 provided in this embodiment has a first guide rail 2211 and a second guide rail 2212. The rotating rod 222 drives the guide member 221 to rotate relative to the main body 1, so that the top rod 211 can move along the first guide rail 2211 and the second guide rail 2212 for switching between water outlet mode and water shut-off mode. The water outlet mode has a quantitative water outlet mode and a non-quantitative water outlet mode.

[0162] For example, the first guide rail 2211 and the second guide rail 2212 are continuous structures disposed on the guide member 221, and the central angle of the first guide rail 2211 is smaller than the central angle of the second guide rail 2212; wherein, when the rotating rod 222 abuts against the first guide rail 2211, the water outlet control structure 2 is in the water shut-off mode; when the rotating rod 222 abuts against the second guide rail 2212, the water outlet control structure 2 is in the quantitative water outlet mode or the non-quantitative water outlet mode.

[0163] Specifically, a groove is provided on the side of the guide member 221 facing the push rod 211. The groove can be a V-shaped structure, and the side wall of the groove is an inclined wall structure, which makes it easy for the push rod 211 to slide into or out of the groove. The groove wall forms a first guide track 2211, and the end face of the guide member 221 without the groove and facing the push rod 211 forms a second guide track 2212.

[0164] When the push rod 211 is located on the first guide rail 2211, the height distance between the first guide rail 2211 and the pressure relief hole 511 is relatively large, and the push rod 211 tends to move upward. Therefore, the second end 2122 at the lowest point of the push rod 211 passes through and seals the pressure relief hole 511, indicating a water shut-off mode. When the push rod 211 is located on the second guide rail 2212, the height distance between the second guide rail 2212 and the pressure relief hole 511 is relatively small, and the push rod 211 tends to move downward. Therefore, the first end 2121 at the upper end of the push rod 211 passes through the pressure relief hole 511, with a gap between the first end 2121 and the pressure relief hole 511, indicating a water outlet mode, i.e., a quantitative water outlet mode or a non-quantitative water outlet mode.

[0165] like Figures 22-24 As shown, the damper 24 provided in this embodiment includes a clutch 243, which is disposed between the second control component 22 and the reset component 23, and is used for the second control component 22 to selectively connect to the reset component 23.

[0166] When the clutch 243 is disengaged, the second control component 22 and the reset component 23 are disconnected. As the water pressure increases, the reset component 23 cannot drive the guide 221 and the rotary rod 222 of the second control component 22 to reset, thus achieving a non-quantitative water output mode. When the clutch 243 is engaged, the second control component 22 and the reset component 23 are connected. As the water pressure increases, the reset component 23 drives the guide 221 and the rotary rod 222 of the second control component 22 to reset, thus achieving a quantitative water output mode and realizing water output control.

[0167] In this way, the quantitative water dispensing mode and the non-quantitative water dispensing mode can share the same second guide rail 2212, and the two water dispensing modes can be distinguished by the clutch 243.

[0168] Specifically, such as Figures 22-24 As shown, the clutch 243 includes a connecting seat 2433, a pawl 2431, and a latch 2432. One of the pawl 2431 and the latch 2432 is disposed on the second control component 22, and the other is disposed on the reset component 23. The connecting seat 2433 is provided with a first guide slope 24331, and the second control component 22 is provided with a second guide slope 2213 on the side facing the connecting seat 2433. The first guide slope 24331 and the second guide slope 2213 slide in cooperation, so that the pawl 2431 and the latch 2432 selectively engage.

[0169] When the user needs to switch to the non-quantitative water dispensing mode, rotating the rotary lever 222 causes the guide member 221 to move. Guided by the rotary lever 222, the second guide slope 2213 of the guide member 221 is raised along the first guide slope 24331 of the connecting seat 2433, causing the claws 2431 and the latches 2432, which are respectively connected to the guide member 221 and the reset assembly 23, to separate. At this time, the impeller assembly 231 and the reduction gear assembly 232 cannot reset the guide member 221 and the rotary lever 222 when they rotate, thus achieving non-quantitative water dispensing. When a mode switch is required, rotating the rotary lever 222 causes the claws 2431 and the latches 2432 to re-engage under the elastic force of the first reset member 213, and the guide member 221 and the reset assembly 23 to reconnect, thus achieving the water shut-off mode and the quantitative water dispensing mode.
