[0091] Embodiment 1

[0092] This embodiment provides a water outlet control mechanism, which is suitable for water outlet scenes such as bathrooms, water dispensers, and beverage machines. Figure 1-Figure 2 As shown, the water outlet control mechanism includes a main body 1 and a water outlet control structure 2. The shape of the main body 1 is similar to a cylindrical structure or a rectangular structure. A cavity is arranged inside the main body 1. The main body 1 is provided with a water inlet 11 and a water outlet 12. The water outlet control structure 2 is at least partially arranged 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 water inlet 11 and the water outlet 12 are selectively connected and switch between a quantitative water outlet mode and a non-quantitative water outlet mode.

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

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

[0095] Among them, the quantitative water outlet mode specifically means that even if water is continuously introduced from the water inlet 11, the flow rate or volume of water discharged from the water outlet 12 is a constant value; the non-quantitative water outlet mode specifically means that if water is continuously introduced from the water inlet 11, the flow rate or volume of water discharged from the water outlet 12 is not a constant value, but changes with the change of the water flow through the water inlet 11.

[0096] The water outlet control mechanism provided in this embodiment can realize free switching between the quantitative water outlet mode and the non-quantitative water outlet mode by using the water outlet control structure 2, which is convenient for users to switch modes during use and improves the user experience. At the same time, the main body 1 is provided with a water inlet 11 and a water outlet 12, and the water paths of the quantitative water outlet mode and the non-quantitative water outlet mode can share the same water inlet 11 and the same water outlet 12, without adding additional water inlets 11 or water outlets 12, thus saving production costs.

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

[0098] It can be understood that the water outlet 12 corresponding to the first station is closed and is in a state where water cannot be discharged, and the water outlet 12 corresponding to the second station is opened and is in a state where water can be discharged. Under the premise of water discharge, the quantitative water discharge mode and the non-quantitative water discharge mode can be further distinguished. Specifically, in the second station, the water discharge control structure 2 can be in a quantitative water discharge mode or a non-quantitative water discharge mode, and the other structures of the water discharge control mechanism can be matched with the water discharge control structure 2 to distinguish the quantitative water discharge mode and the non-quantitative water discharge mode to avoid interference with the water discharge mode. In the second station, the water discharge control structure 2 can be in a quantitative water discharge mode and a non-quantitative water discharge mode, and the water discharge control structure 2 can be refined by its own structure to divide different interval stations, corresponding to the quantitative water discharge mode and the non-quantitative water discharge mode, respectively.

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

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

[0101] Among them, the first sub-station and the second sub-station are respectively arranged on both sides of the first station along the circumferential direction of the main body 1, and the water outlet control structure 2 is configured to rotate relative to the main body 1 for switching between the first sub-station and the second sub-station.

[0102] In this way, the two sub-stations correspond to the quantitative water outlet mode and the non-quantitative water outlet mode respectively. By rotating the water outlet control structure 2, the switching between the two sub-stations can be achieved, thereby realizing the switching between the quantitative water outlet mode and the non-quantitative water outlet mode, which is convenient for users to operate.

[0103] In one embodiment, Figure 2 As shown, the water outlet control mechanism also includes an inner shell 4, which is at least partially arranged in the cavity of the main body 1, and the water outlet control structure 2 is passed 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 channel in the inner shell 4.

[0104] For example, 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 arranged inside the main body 1. The bottom cover 42 and the top cover 43 are respectively arranged at the two 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 surface of the shell 41, and a pressing member 44 is arranged on the outside of the other end. The pressing member 44 is specifically a gland nut. The pressing member 44 is sleeved on the outside of the top cover 43 and is used to lock the shell 41 and the top cover 43. The bottom cover 42 is arranged at one end of the main body 1 close to the water inlet 11 and is arranged corresponding to the water inlet 11. The outer wall of the bottom cover 42 does not fit the inner wall of the main body 1, and a gap is arranged between the bottom cover 42 and the inner wall of the main body 1. The gap is connected to the water inlet 11 and the water outlet 12 respectively, and is used to transport the water flowing in from the water inlet 11 to the water outlet 12 through the gap.

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

[0106] Specifically, Figure 2 and Figure 5 As shown, the peripheral side wall of the shell 41 is spaced apart with a second water inlet hole 411 and a second water outlet hole 412, and the second water inlet hole 411 and the second water outlet hole 412 are arranged in layers up and down, the second water inlet hole 411 is arranged close to the water inlet 11 and is connected with the first water outlet hole 422, the second water outlet hole 412 is arranged corresponding to the water outlet 12 and is connected with each other, the water in the gap is passed into the inner cavity of the shell 41 through the second water inlet hole 411, and the water outlet control structure 2 controls the switching of the water path in the shell 41, so that the water is transported to the water outlet 12 through the second water outlet hole 412 for discharge.

[0107] In one embodiment, Figure 2-Figure 7 As shown, the water outlet control mechanism further includes a pilot control structure 5 , which is disposed in the inner shell 4 and between the water inlet 11 and the water outlet control structure 2 , and is used for selectively blocking 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., the quantitative water outlet mode or the non-quantitative water outlet mode. Since the pilot control structure 5 is arranged between the water inlet 11 and the water outlet control structure 2, the pilot control structure 5 can control the water path better than the water outlet control structure 2, realize the pilot function, improve the control accuracy, and reduce the risk of water leakage in the closed mode to a certain extent.

[0109] Specifically, 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 arranged between the housing 41 and the bottom cover 42. The pilot seat 51 is made of elastic material, and the pilot seat 51 can also be called a leather cup seat. The pilot valve 52 is made of elastic material, and the pilot valve 52 can also be called a leather cup. The pilot valve 52 is arranged in the pilot seat 51 and slidably cooperates with the pilot seat 51. The pilot valve 52 is used to selectively block the pilot hole 420. Among them, a guide column is convexly provided on the side of the pilot seat 51 facing the pilot valve 52. The guide column penetrates the pilot valve 52 and the pilot hole 420. The pilot valve 52 can slide along the axial direction of the guide column to play a guiding role, so as to avoid a large position offset of the pilot valve 52 during the movement.

[0110] In one embodiment, Figure 2 , Figure 6 and Figure 7 As shown, the water outlet control structure 2 includes a first control assembly 21 and a second control assembly 22. The first control assembly is disposed in the main body 1. A pressure relief hole 511 is disposed in the main body 1. The pressure relief hole 511 is specifically disposed on a pilot seat 51 in the main body 1. The pressure relief hole 511 is disposed between the water inlet 11 and the water outlet 12. The second control assembly 22 is at least partially disposed in the main body 1 and abuts against the first control assembly 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 one 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 offset and the pressure relief hole 511 is not blocked, the water flowing out from the pilot hole 420 can enter the pilot seat 51, and then flow into the shell 41 through the pressure relief hole 511, and finally be discharged from the water 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 in the pressure relief hole 511, since the pressure relief hole 511 is arranged 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 of the pilot hole 420 cannot enter the shell 41 through the pilot seat 51, and is in the water-off mode, or is used to end the quantitative water outlet mode, so as to more accurately control the water output of the quantitative water outlet 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, which is convenient for users to operate.

[0115] In one embodiment, Figure 2 , Figure 6 and Figure 7 As shown, the first control component 21 includes a push rod 211, one end of the push rod 211 is abutted against the second control component 22, and the other end is provided with a control end 212, and the control end 212 is used to control the opening and closing of the pressure relief hole 511, wherein the push rod 211 and the control end 212 can be a split structure, which is convenient for the replacement and maintenance of the control end 212 that is used for a long time, and the push rod 211 and the control end 212 can also 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 that are 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 is passed through the pressure relief hole 511 and has a clearance fit with the pressure relief hole 511, and the second end 2122 is passed through the pressure relief hole 511 and has an interference fit with the pressure relief hole 511.

[0117] like Figure 2 As shown, when the first end 2121 is located in 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, and the water in the pilot control structure 5 can enter the inner shell 4 through the gap, which is used to realize the quantitative water outlet mode and the non-quantitative water outlet mode.

[0118] like Figure 8 As shown, when the second end 2122 is located in 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 fit tightly, and the water in the pilot control structure 5 cannot enter the inner shell 4 through the gap, so as to realize the water shut-off mode.

[0119] Under the control of the second control assembly 22, the push rod 211 can achieve mode switching by moving up and down along the axial direction of the main body 1, which is easy to operate and use.

[0120] It can be understood that the number of the first end 2121 and the second end 2122 can be one, that is, the top rod 211 has only one corresponding water outlet mode position or one corresponding water off mode position during the 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 off mode positions. Fig. 9As shown, the number of the first ends 2121 is two, and the two first ends 2121 are arranged at both ends of the second end 2122 along the axial direction of the main body 1. Then, the outer diameter of the end of the control end 212 close to the pressure relief hole 511 forms small, large, and small structures, which can respectively correspond to two different water outlet modes: quantitative water outlet mode and non-quantitative water outlet mode.

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

[0122] In one embodiment, the first control assembly 21 further includes a stopper 214, which is disposed in the housing 41 of the main body 1. The stopper 214 is provided with a first guide through hole, and the top rod 211 is passed through the first guide through hole and can slide relative thereto, and the first guide through hole plays a guiding role. At the same time, the two ends of the first reset member 213 are respectively abutted against the guide seat 51 of the guide control structure and the stopper 214 or the inner wall of the housing 41, and the stopper 214 or the housing 41 provides a support position for the first reset member 213, so as to facilitate the reset function of the first reset member 213.

[0123] In one embodiment, the first control component 21 also includes a first seal 215, which is disposed in the pressure relief hole 511. When the second end 2122 of the top rod 211 is inserted into the pressure relief hole 511, the second end 2122 can fit tightly with the first seal 215 to improve the sealing effect, prevent the risk of water leakage in the water-off mode, and improve the sealing effect of the water-off mode.

[0124] In one embodiment, Figure 2 , Figure 11-13As shown, the second control assembly 22 includes a guide member 221, which can be called a guide wheel or a special-shaped wheel. The guide member 221 abuts against the top rod 211. The guide member 221 is provided with a first guide track 2211 and a second guide track 2212 on the side facing the first control assembly 21. The top rod 211 can move along the first guide track 2211 and the second guide track 2212. The two guide tracks of the guide member 221 play the role of providing a planning path for the top rod 211, so that the top rod 211 has different height positions. Among them, the first guide track 2211 corresponds to the first station, and the second guide track 2212 corresponds to the second station.

[0125] Exemplarily, a groove is provided on the side of the guide member 221 facing the water inlet 11, and the notch of the groove is provided toward the water inlet 11. The bottom of the groove can form at least one of the first guide track 2211 and the second guide track 2212. The shape of the groove can be regular or irregular. One of the first guide track 2211 and the second guide track 2212 can also be the end surface of the guide member 221 facing the water inlet 11. The present embodiment does not limit the setting position and shape of the first guide track 2211 and the second guide track 2212. As long as there is a difference in the height position of the two guide tracks along the axial direction of the main body 1, that is, the distance between the two guide tracks and the pressure relief hole 511 is different, under the guiding action of the two guide tracks, the movement displacement of the top rod 211 along the axial direction of the main body 1 is different, resulting in the control end 212 of the top rod 211 being inserted into the pressure relief hole 511 at different positions, so that the switching between the water outlet mode and the water shut-off mode can be realized.

[0126] In one embodiment, the second control component 22 also includes a rotating rod 222, which is passed through the guide member 221. 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, which is used for switching between the water outlet mode and the water off mode.

[0127] In actual use, the user can operate the screw rotation, and the rotary rod 222 drives the guide member 221 to rotate. Under the elastic force of the first reset member 213, the top rod 211 is closely abutted against the guide member 221. As the guide member 221 rotates, the guide member 221 can guide the top rod 211 to move along the first guide track 2211 and the second guide track 2212, which is convenient for mode switching. The first guide track 2211 corresponds to the first station, the water inlet 11 and the water outlet 12 are not connected, and are in the water shut-off mode. The second guide track 2212 corresponds to the second station, and the water outlet control structure 2 is in the water outlet mode, that is, the quantitative water outlet mode and / or the non-quantitative water outlet mode.

[0128] In one embodiment, the first guide track 2211 and the second guide track 2212 are continuous structures provided on the guide member 221. In this way, there will be no interruption in the mode switching, and the continuity of the mode switching is ensured, so as to ensure 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; when the rotary rod 222 abuts against the first guide rail 2211, the water outlet control structure 2 is in the water-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 way, since the first guide track 2211 corresponds to the water shut-off mode, the center angle of the first guide track 2211 is relatively small, and the space occupied by the guide member 221 is not wasted, and the water shut-off time can be shortened, which can achieve the timeliness of water shut-off and a relatively fast response speed. Since the second guide track 2212 corresponds to the water outlet mode, the center angle of the second guide track 2212 is relatively large, which fully occupies the space position of the guide member 221, increases the coverage of the second guide track 2212 on the guide member 221, ensures the time required in the water outlet mode, and improves the accuracy of water outlet.

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

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

[0133] In this way, since the first sub-track 22121 corresponds to the quantitative water outlet mode, the process of the top rod 211 moving along the first sub-track 22121 corresponds to the process of quantitative water outlet 12, and the center angle of the first guide track 2211 is relatively large, which fully occupies the spatial position of the guide member 221, increases the coverage of the first guide track 2211 on the guide member 221, ensures the time required in the quantitative water outlet mode, and improves the accuracy of water outlet. Since the second sub-track 22122 corresponds to the non-quantitative water outlet mode, the center angle of the second sub-track 22122 is relatively small, and when the second end 2122 of the top rod 211 is inserted into the pressure relief hole 511, continuous water outlet can be achieved without wasting the coverage of the second sub-track 22122 on the guide member 221.

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

[0135] Since the control end 212 of the top rod 211 has a first end 2121 and two second ends 2122, the two second ends 2122 are arranged at both ends of the first end 2121, that is, along the axial direction of the main body 1 and toward 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 top rod 211 abuts against the second sub-track 22122 with the highest height position, the top rod 211 is in the highest position of movement, and the first end 2121 located at the lowermost end of the top rod 211 is penetrated by the pressure relief hole 511, and water can be transported to the inner shell 4 through the pressure relief hole 511 to realize a non-quantitative water outlet mode. When the top rod 211 abuts against the first guide track 2211 at the middle height position, the top rod 211 has a tendency to drop downward, and the second end 2122 located in the middle of the top rod 211 is penetrated in the pressure relief hole 511, and the second end 2122 is blocked in the pressure relief hole 511, so that water cannot be transported to the inner shell 4 through the pressure relief hole 511, and the water shut-off mode is realized. When the top rod 211 abuts against the first sub-track 22121 at the lowest height position, the top rod 211 has a tendency to continue to drop downward, and the first end 2121 located at the uppermost end of the top rod 211 is penetrated in the pressure relief hole 511, so that water can be transported to the inner shell 4 through the pressure relief hole 511. The center angle of the first sub-track 22121 is relatively large. When the rotation angle of the guide member 221 is just the center angle of the first sub-track 22121, the quantitative water discharge mode ends.

[0136] It should be particularly 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 water inlet 11, the bottom wall of the groove is a gradual structure, one side wall of the groove is a straight arm structure, and the other side wall is a slope structure, which is just connected to 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 interval near the straight wall of the groove, the first guide track 2211 actually corresponds to the interval near the slope structure of the groove, and the first sub-track 22121 corresponds to the end face portion of the guide member 221 facing the water inlet 11.

[0137] In one embodiment, Figure 2-Figure 12 As shown, the water outlet control structure 2 also includes a reset component 23, which is arranged in 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 to ensure the accuracy and reliability of 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 the action of water pressure, the impeller assembly 231 rotates counterclockwise relative to the main body 1, and the impeller 2312 drives the reduction gear assembly 232 to rotate. The reduction gear assembly 232 plays a role of deceleration to avoid the situation where the water flow speed is too fast and the water discharge time in the quantitative water discharge mode is relatively short. The reduction gear assembly 232 drives the second control component 22 to rotate counterclockwise. During the rotation of the guide member 221, the elastic recovery force of the top rod 211 on the first reset member 213 slowly moves upward along the first sub-track 22121 to the first guide track 2211, corresponding to the closed position, and the second end 2122 is blocked in the pressure relief hole 511 to stop the water discharge.

[0141] Specifically, Figure 2-Figure 12As shown, the impeller assembly 231 includes an impeller box 2311 and an impeller 2312. The impeller 2312 is arranged in the impeller box 2311, and the impeller box 2311 provides support for the impeller 2312. The stopper 214 is arranged on the impeller box 2311 or the impeller 2312 to provide a support position for the stopper 214. Of course, a second guide through hole is also provided on the impeller box 2311, and the push rod 211 is penetrated through the second guide through hole and slidably cooperates with the second guide through hole to play a guiding role, thereby improving the alignment accuracy of the push rod 211 and the pressure relief hole 511.

[0142] Specifically, Figure 2-Figure 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 group 231 is connected to the first gear 2321, the first gear 2321 and the second gear 2322 are meshed, the second gear 2322 is meshed with the third gear 2323, the third gear 2323 is meshed with the fourth gear 2324, and the fourth gear 2324 is connected to the guide member 221 of the second control assembly 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 the second gear 2322 and the third gear 2323 can be one or more, and the guide shaft is provided through multiple second gears 2322 or multiple third gears 2323 to form different gear combinations.

[0143] In one embodiment, Fig.10 As shown, the water outlet control mechanism also includes a limiting structure 3, which is arranged between the reset component 23 and the first control component 21, and is used for limiting between the first control component 21 and the reset component 23, and for locking the water outlet control structure 2 in the non-quantitative water outlet mode.

[0144] Exemplarily, a limit 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 limit groove. When the top rod 211 is at the highest position, the limit block 31 and the raised rib 32 are at the same height. The limit block 31 prevents the impeller 2312 from rotating, the guide member 221 will not rotate, and the top rod 211 cannot be reset, thereby ensuring the stability of the non-quantitative water outlet mode.

[0145] In one embodiment, Figure 2 , Figure 14-15 As shown, the water outlet control structure 2 further 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 unidirectionally transmitted to the second control component 22 through the damper 24 .

[0146] In this way, when the user switches the mode and rotates the rotary rod 222, the rotary rod 222 will drive the guide member 221 to rotate, but will not drive the reduction gear group 232 and the impeller group 231 to rotate. However, when 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, which is used to reset the guide member 221 and to close the quantitative water outlet mode.

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

[0148] Among them, the second reset member 242 can be a disc spring, the gasket 241 can be a wear-resistant gasket, and the rotating rod 222 and the fourth gear 2324 are structures that can rotate with each other, but there is a mutual friction. The second reset member 242 and the wear-resistant gasket 241 are arranged between the rotating rod 222 and the fourth gear 2324, and the second reset member 242 is fixed and compressed by the stainless steel pad 240 and the shaft shoulder of the rotating rod 222. When the rotating rod 222 is switched to the quantitative water discharge mode, the rotating rod 222 is rotated. Since the fourth gear 2324 and the other gears of the reduction gear set 232 are meshed, under the action of the reduction gear set 232, the fourth gear 2324 cannot rotate, and the rotating rod 222 overcomes the friction between the fourth gear 2324 and the fourth gear 2324 and rotates. In the quantitative water discharge mode, the impeller group 231 drives the reduction gear set 232 to rotate. As the fourth gear 2324 rotates, the fourth gear 2324 drives the guide member 221 and the rotating rod 222 to reset under the action of the friction force.

[0149] In one embodiment, Figure 2 , Figure 6 and Figure 7 As shown, the second control assembly 22 also includes a handle 223, a retaining ring 224, and a sealing ring 225. The rotating rod 222 is inserted into the handle 223 and fixed by a nut 226. The handle 223 is used to facilitate the user to operate and rotate the rotating rod 222. The retaining ring 224 is sleeved on the outside of the rotating rod 222 and is arranged between the rotating rod 222 and the top cover 43, and is used to reset the rotating rod 222. The sealing ring 225 is sleeved on the outside of the rotating rod 222 and is arranged between the rotating rod 222 and the top cover 43, and is used to ensure the sealing 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 restoring member 242 is greater than the resistance friction of the second control component 22 relative to the main 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, the sealing ring 225, the retaining spring 224, etc. By utilizing the 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, and when the mode is switched, the rotary rod 222 will not carry away the second reset member 242, thereby ensuring the reliability of the mode switching.

[0152] This embodiment also provides a water outlet device, including the above-mentioned water outlet control mechanism, and the water outlet control structure 2 can be used to realize free switching between the quantitative water outlet mode and the non-quantitative water outlet mode, which is convenient for users to switch modes during use, thereby improving the user experience. At the same time, the main body 1 is provided with a water inlet 11 and a water outlet 12, and the water paths of the quantitative water outlet mode and the non-quantitative water outlet mode can share the same water inlet 11 and the same water outlet 12, without adding additional water inlets 11 or water outlets 12, thereby saving production costs.

[0153] This embodiment also provides a water outlet control mechanism, such as Figure 1-Figure 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 a water inlet 11 and a water outlet 12; the water outlet control structure 2 is at least partially arranged in the main body 1, and 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 water inlet 11 and the water outlet 12 are selectively connected, which is used for opening and closing the quantitative water outlet mode; the reset component 23 is arranged between the first control component 21 and the second control component 22, and the reset component 23 can drive the second control component 22 to rotate relative to the main body 1, which is used for resetting the second control component 22; the damper 24 is arranged between the second control component 22 and the reset component 23, so that the rotational force of the reset component 23 can be unidirectionally transmitted to the second control component 22 through the damper 24.

[0154] When the second control assembly 22 rotates relative to the main body 1 and drives the first control assembly 21 to move along the main body 1 in the axial direction of the main body 1, the water inlet 11 and the water outlet 12 are not connected. That is, the first control assembly 21 and the pressure relief hole 511 are staggered and the pressure relief hole 511 is not blocked, and the water flowing out of the pilot hole 420 can enter the pilot seat 51, and then flow into the housing 41 through the pressure relief hole 511, and finally be discharged from the water outlet 12 through the second water outlet hole 412, and 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 main body 1 in the axial direction of the main body 1, the water inlet 11 and the water outlet 12 are connected to each other. That is, the first control component 21 is blocked at the pressure relief hole 511. Since the pressure relief hole 511 is arranged 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 of the pilot hole 420 cannot enter the housing 41 through the pilot seat 51, and is in the water shut-off mode, or is used to end the quantitative water outlet mode, and more accurately controls the water output of the quantitative water outlet mode.

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

[0157] The rotational force of the reset component 23 can be transmitted unidirectionally to the second control component 22 through the damper 24. In this way, when the user switches the mode and rotates the rotary rod 222, the rotary rod 222 will drive the guide member 221 to rotate, but will not drive the reduction gear group 232 and the impeller group 231 to rotate. However, when 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, which is used to reset the guide member 221 and to close the quantitative water outlet mode.

[0158] Embodiment 2

[0159] This embodiment is similar to the first embodiment, and the difference lies only in the specific detailed structures of the control end 212 , the guide member 221 and the damper 24 .

[0160] like Figure 16-Figure 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, and the number of the first end 2121 and the second end 2122 are both one. The first end 2121 is penetrated through the pressure relief hole 511 and has a clearance fit with the pressure relief hole 511, and the second end 2122 is penetrated through the pressure relief hole 511 and has an interference fit with the pressure relief hole 511.

[0161] The guide member 221 provided in this embodiment has a first guide track 2211 and a second guide track 2212. 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 track 2211 and the second guide track 2212, which is used for switching between the water outlet mode and the water off mode. The water outlet mode includes a quantitative water outlet mode and a non-quantitative water outlet mode.

[0162] Exemplarily, the first guide rail 2211 and the second guide rail 2212 are continuous structures arranged 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 rotary rod 222 abuts against the first guide rail 2211, the water outlet control structure 2 is in the water-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 or the non-quantitative water outlet mode.

[0163] Specifically, a groove is provided on the side of the guide member 221 facing the top rod 211. The groove may be a V-shaped structure. The side wall of the groove is an inclined wall structure, which facilitates the top rod 211 to slide in or out of the groove. The groove wall forms a first guide track 2211. The guide member 221 is not provided with a groove portion and the end face facing the side of the top rod 211 forms a second guide track 2212.

[0164] When the top rod 211 is located on the first guide track 2211, the height distance between the first guide track 2211 and the pressure relief hole 511 is relatively large, and the top rod 211 has a tendency to move upward, then the second end 2122 located at the lowest end of the top rod 211 is penetrated through the pressure relief hole 511 and blocked at the pressure relief hole 511, and the water is in the water shut-off mode. When the top rod 211 is located on the second guide track 2212, the height distance between the second guide track 2212 and the pressure relief hole 511 is relatively small, and the top rod 211 has a tendency to move downward, then the first end 2121 located at the upper end of the top rod 211 is penetrated through the pressure relief hole 511, and there is a gap between the first end 2121 and the pressure relief hole 511, and the water is in the water outlet mode, that is, the quantitative water outlet mode or the non-quantitative water outlet mode.

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

[0166] When the clutch 243 is in a disengaged state, 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 member 221 and the rotary rod 222 of the second control component 22 to reset, thereby realizing a non-quantitative water outlet mode; when the clutch 243 is in a closed state, the second control component 22 and the reset component 23 are connected. As the water pressure increases, the reset component 23 drives the guide member 221 and the rotary rod 222 of the second control component 22 to reset, thereby realizing a quantitative water outlet mode and achieving water outlet control.

[0167] In this way, the quantitative water outlet mode and the non-quantitative water outlet mode can share the same second guide track 2212, and the clutch 243 is used to distinguish between the quantitative water outlet mode and the non-quantitative water outlet mode.

[0168] Specifically, Figure 22-Figure 24 As shown, the clutch 243 includes a connecting seat 2433, a claw 2431 and a buckle 2432, one of the claw 2431 and the buckle 2432 is arranged on the second control component 22, and the other is arranged 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 are slidably matched, so that the claw 2431 and the buckle 2432 are selectively engaged.

[0169] When the user needs to switch to the non-quantitative water outlet mode, the user rotates the rotary rod 222, and the rotary rod 222 drives the guide member 221. The guide member 221 is guided by the rotary rod 222, and the second guide slope 2213 of the guide member 221 is raised along the first guide slope 24331 of the connecting seat 2433, so that the claw 2431 and the buckle 2432 connected to the guide member 221 and the reset assembly 23 are separated, and the impeller group 231 and the reduction gear group 232 cannot reset the guide member 221 and the rotary rod 222 when they rotate, so that the non-quantitative water outlet is realized. When the mode switching is needed, the rotary rod 222 is rotated, and the claw 2431 and the buckle 2432 are re-engaged under the action of the elastic force of the first reset member 213, and the guide member 221 and the reset assembly 23 are reconnected, so that the water off mode and the quantitative water outlet mode are realized.
