[0078] Embodiment One

[0079] The embodiment provides a water outlet control mechanism suitable for water outlet scenes such as bathrooms, water dispensers, beverage machines, etc., as shown in FIGS. 1-2, which includes a main body 1 and a water outlet control structure 2. The main body 1 is similar in shape to a cylindrical structure or a cuboid structure, and is provided with a cavity inside. 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 to selectively communicate the water inlet 11 and the water outlet 12, and switch between the quantitative water outlet mode and the non-quantitative water outlet mode.

[0080] 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 arranged at two ends of the main body 1 along the axial direction of the main body 1. The present embodiment does not limit the arrangement positions of the water inlet 11 and the water outlet 12, and the arrangement positions can be adjusted according to actual production needs.

[0081] When the water inlet 11 and the water outlet 12 are not connected, the water outlet control mechanism is in the water-off mode; when the water inlet 11 and the water outlet 12 are connected, the water outlet control mechanism is in the water-out mode, and the water-out mode has a quantitative water-out mode and a non-quantitative water-out mode.

[0082] The quantitative water-out mode specifically means that even if water is continuously supplied from the water inlet 11, the flow rate or volume of water discharged from the water outlet 12 is a constant value; and the non-quantitative water-out mode specifically means that if water is continuously supplied 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 water supply amount of the water inlet 11.

[0083] The water outlet control mechanism provided in the present embodiment can realize free switching between the quantitative water-out mode and the non-quantitative water-out mode by using the water outlet control structure 2, so that the mode switching is convenient for users when the users use the water outlet control mechanism, and the use experience of the users is improved. Meanwhile, the main body 1 is provided with the water inlet 11 and the water outlet 12, and the water paths of the quantitative water-out mode and the non-quantitative water-out mode can share the same water inlet 11 and the same water outlet 12, so that no additional water inlet 11 or water outlet 12 needs to be added, and the production manufacturing cost is saved.

[0084] 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 water inlet 11 and the water outlet 12 are not connected; and when the water outlet control structure 2 is located at the second station, the water outlet control structure 2 is in the quantitative water-out mode and / or the non-quantitative water-out mode.

[0085] It can be understood that the first station corresponds to the water outlet 12 being closed and being in a state of being unable to discharge water, and the second station corresponds to the water outlet 12 being opened and being in a state of being able to discharge water. In the case of discharging water, 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 the quantitative water discharge mode or the non-quantitative water discharge mode. The quantitative water discharge mode and the non-quantitative water discharge mode can be distinguished by other structures of the water discharge control mechanism cooperating with the water discharge control structure 2, so as to avoid interference of the water discharge mode. In the second station, the water discharge control structure 2 can be in the quantitative water discharge mode and the non-quantitative water discharge mode. The quantitative water discharge mode and the non-quantitative water discharge mode can be refined by the structure of the water discharge control structure 2 itself, different interval stations are divided, and the quantitative water discharge mode and the non-quantitative water discharge mode are respectively corresponded.

[0086] The first station and the second station are arranged along the circumferential direction of the main body 1, and the water discharge 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 discharge control structure 2, switching between the first station and the second station can be realized, and the user operation is convenient to use.

[0087] In one embodiment, the second station includes a first sub-station and a second sub-station. When the water discharge control structure 2 is located in the first sub-station, the water discharge control structure 2 is in the quantitative water discharge mode. When the water discharge control structure 2 is located in the second sub-station, the water discharge control structure 2 is in the non-quantitative water discharge mode.

[0088] 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 discharge 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.

[0089] In this way, the two sub-stations respectively correspond to the quantitative water discharge mode and the non-quantitative water discharge mode. By rotating the water discharge control structure 2, switching between the two sub-stations can be realized, so as to realize switching between the quantitative water discharge mode and the non-quantitative water discharge mode. The user operation is convenient to use.

[0095] When the pilot control structure 5 is blocked in the pilot hole 420, the water outlet control mechanism is in the closed mode; when the pilot control structure 5 is disengaged 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 before the water outlet control structure 2, realize the pilot function, improve the accuracy of control, and to some extent, reduce the risk of water leakage in the closed mode.

[0098] The second control assembly 22 is configured to rotate relative to the main body 1, and to drive the first control assembly 21 to move along the axial direction of the main body 1, so that the first control assembly 21 controls the end away from the second control assembly 22 to selectively block the pressure relief hole 511.

[0099] When the first control assembly 21 and the pressure relief hole 511 are disengaged and do not block the pressure relief hole 511, the water flowing out of the pilot hole 420 can enter the pilot seat 51, and then flow to 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, i.e. the quantitative water outlet mode or the non-quantitative water outlet mode.

[0100] When the first control assembly 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 for ending the quantitative water discharge mode, more accurately controlling the water discharge amount of the quantitative water discharge mode.

[0101] With the rotation of the second control assembly 22, the first control assembly 21 can convert the rotation of the second control assembly 22 into movement in the axial direction of the main body 1, realizing the switching of the water discharge mode (quantitative water discharge mode and non-quantitative water discharge mode) and the water-off mode, facilitating user operation and use.

[0102] In one embodiment, as shown in FIGS. 2, 6 and 7, the first control assembly 21 includes a top rod 211, one end of the top rod 211 abuts against the second control assembly 22, and the other end is provided with a control end 212 for controlling the opening and closing of the pressure relief hole 511, wherein the top rod 211 and the control end 212 can be a split structure, facilitating replacement and maintenance of the control end 212 for long-term use, or an integral structure, reducing the assembly link of parts and saving production cost.

[0103] Specifically, the control end 212 includes a coaxially arranged first end 2121 and a second end 2122, the outer diameter of the first end 2121 is smaller than that of the second end 2122, the first end 2121 is arranged in the pressure relief hole 511 and gap-fitted with the pressure relief hole 511, and the second end 2122 is arranged in the pressure relief hole 511 and interference-fitted with the pressure relief hole 511.

[0104] As shown in FIG. 2, when the first end 2121 is located in the pressure relief hole 511, since the first end 2121 and the pressure relief hole 511 are gap-fitted, 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, for realizing the quantitative water discharge mode and the non-quantitative water discharge mode.

[0105] As shown in FIG. 8, when the second end 2122 is located in the pressure relief hole 511, since the second end 2122 and the pressure relief hole 511 are interference-fitted, 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, for realizing the water-off mode.

[0106] Under the control of the second control assembly 22, the top rod 211 can realize mode switching by moving up and down in the axial direction of the main body 1, which is convenient to operate and use.

[0107] 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 in the movement process; the number of at least one of the first end 2121 and the second end 2122 can be multiple, which can correspond to multiple water outlet mode positions or water off mode positions. For example, as shown in FIG. 9, the number of the first end 2121 is two, and the two first ends 2121 are arranged at the two ends of the second end 2122 in the axial direction of the main body 1. The outer diameter of the end of the control end 212 close to the pressure relief hole 511 forms a small-large-small structure, which can correspond to two different water outlet modes of the quantitative water outlet mode and the non-quantitative water outlet mode.

[0108] As shown in FIGS. 2-9, the first control assembly 21 further comprises a first reset member 213, which can be a spring in particular. The first reset member 213 is sleeved on the outside of the top rod 211 and is used for resetting the top rod 211. In this way, in the process that the second control assembly 22 controls the top rod 211 to move in the axial direction of the main body 1 and towards the water inlet 11, the top 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 rebounding movement tendency under the self-restoring force to drive the top rod 211 to reset, so as to ensure the continuity and reliability of the next mode switching.

[0109] In an embodiment, the first control assembly 21 further comprises a stop block 214 arranged in the shell 41 of the main body 1. The stop block 214 is provided with a first guide through hole, and the top rod 211 passes through the first guide through hole and can slide relative to the first guide through hole. The first guide through hole plays a guiding role. Meanwhile, the two ends of the first reset member 213 abut against the pilot seat 51 of the guide control structure and the stop block 214 or the inner wall of the shell 41 respectively. The stop block 214 or the shell 41 provides a support position for the first reset member 213, so as to facilitate the resetting function of the first reset member 213.

[0110] In an embodiment, the first control assembly 21 further comprises a first sealing member 215 arranged in the pressure relief hole 511. When the second end 2122 of the top rod 211 passes through the pressure relief hole 511, the second end 2122 can tightly abut against the first sealing member 215, thereby improving the plugging effect and preventing the risk of water leakage in the water off mode, and improving the sealing effect of the water off mode.

[0111] In one embodiment, as shown in FIG. 2, FIG. 11-13, the second control assembly 22 comprises a guide 221, which can be referred to as a guide wheel or a profiled wheel, abutting against the top rod 211, and provided with a first guide track 2211 and a second guide track 2212 on one side of the first control assembly 21, and the top rod 211 is capable of moving along the first guide track 2211 and the second guide track 2212, and the two guide tracks of the guide 221 provide a planned path for the top rod 211 to have 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.

[0112] Exemplarily, the guide 221 is provided with a groove on one side facing the water inlet 11, the groove is provided with a groove opening facing the water inlet 11, and the groove bottom can form at least one of the first guide track 2211 and the second guide track 2212, and the shape of the groove can be regular or irregular, and one of the first guide track 2211 and the second guide track 2212 can also be the end face of the guide 221 on one side 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 the height positions of the two guide tracks are different along the axial direction of the main body 1, that is, the distances between the two guide tracks and the pressure relief hole 511 are different, and under the guidance of the two guide tracks, the movement displacement of the top rod 211 along the axial direction of the main body 1 is different, which causes the control end 212 of the top rod 211 to pass through the pressure relief hole 511 at different positions, thereby realizing the switching between the water outlet mode and the water off mode.

[0113] In one embodiment, the second control assembly 22 further comprises a rotating rod 222, which is provided through the guide 221, and the rotating rod 222 drives the guide 221 to rotate relative to the main body 1, so that the top rod 211 is capable of moving along the first guide track 2211 and the second guide track 2212, for switching between the water outlet mode and the water off mode.

[0114] In actual use, the user can operate the rotating screw to rotate, the rotating rod 222 drives the guide 221 to rotate, and under the elastic force of the first reset member 213, the top rod 211 tightly abuts against the guide 221, and with the rotation of the guide 221, the guide 221 can guide the top rod 211 to move along the first guide track 2211 and the second guide track 2212, facilitating mode switching. Among them, the first guide track 2211 corresponds to the first station, and the water inlet 11 and the water outlet 12 are not connected, in the water off mode, and 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.

[0115] In one embodiment, the first guide rail 2211 and the second guide rail 2212 are continuous structures arranged on the guide member 221. In this way, there is no discontinuity in mode switching, ensuring the continuity of mode switching, to ensure the smoothness and convenience of the switching operation.

[0116] 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 rotating rod 222 abuts against the first guide rail 2211, the water outlet control structure 2 is in the water-off mode; when the rotating rod 222 abuts against the second guide rail 2212, the water outlet control structure 2 is in the constant water outlet mode and / or the non-constant water outlet mode.

[0117] In this way, since the first guide rail 2211 corresponds to the water-off mode, the central angle of the first guide rail 2211 is relatively small, without wasting the space position occupied by the guide member 221, and can also shorten the water-off time, which can achieve the timeliness of water-off and a relatively fast response speed. Since the second guide rail 2212 corresponds to the water outlet mode, the central angle of the second guide rail 2212 is relatively large, fully occupying the space position of the guide member 221, increasing the coverage range of the second guide rail 2212 in the guide member 221, ensuring the required time in the water outlet mode, and improving the accuracy of water outlet.

[0118] In one embodiment, as shown in FIGS. 2, 11-13, 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 arranged on both sides of the first guide rail 2211 along the circumferential direction of the main body 1, and the first sub-rail 22121 and the second sub-rail 22122 are continuous structures arranged 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;

[0119] As shown in FIG. 10, when the rotating rod 222 abuts against the second sub-rail 22122, the water outlet control structure 2 is in the non-constant water outlet mode. As shown in FIG. 11, when the rotating rod 222 abuts against the first guide rail 2211, the water outlet control structure 2 is in the water-off mode. As shown in FIG. 12, when the rotating rod 222 abuts against the first sub-rail 22121, the water outlet control structure 2 is in the constant water outlet mode;

[0120] 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 the water outlet 12 quantitatively discharging water, the central angle of the first guide track 2211 is relatively large, fully occupies the spatial position of the guide 221, increases the coverage range of the first guide track 2211 in the guide 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 central angle of the second sub-track 22122 is relatively small, when the second end 2122 of the top rod 211 penetrates the pressure relief hole 511, continuous water outlet can be realized, and the coverage range of the second sub-track 22122 in the guide 221 is not wasted.

[0121] Specifically, the distance between the first sub-track 22121 and the water inlet 11 is less than the distance between the second sub-track 22122 and the water inlet 11.

[0122] 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, in 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 sequentially arranged, the second sub-track 22122, the first guide track 2211 and the first sub-track 22121 are sequentially arranged and connected with each other, when the top rod 211 abuts against the second sub-track 22122 with the highest height, the top rod 211 is at the highest position of movement, then the first end 2121 at the lowermost end of the top rod 211 penetrates the pressure relief hole 511, water can be delivered to the inner shell 4 through the pressure relief hole 511 to realize the non-quantitative water outlet mode. When the top rod 211 abuts against the first guide track 2211 at the intermediate height, the top rod 211 has a downward downward trend, then the second end 2122 at the middle of the top rod 211 penetrates the pressure relief hole 511, the second end 2122 is blocked in the pressure relief hole 511, water cannot be delivered to the inner shell 4 through the pressure relief hole 511, and the water is turned off. When the top rod 211 abuts against the first sub-track 22121 with the lowest height, the top rod 211 has a downward trend, then the first end 2121 at the uppermost end of the top rod 211 penetrates the pressure relief hole 511, water can be delivered to the inner shell 4 through the pressure relief hole 511, the central angle of the first sub-track 22121 is relatively large, when the rotation angle of the guide 221 is just the central angle of the first sub-track 22121, the quantitative water outlet mode ends.

[0123] It needs to be particularly pointed out 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 and the like of the guide 221. For example, a groove is arranged on the side of the guide 221 facing the water inlet 11, the bottom wall of the groove is a gradient structure, one side wall of the groove is a straight arm structure, and the other side wall is a slope structure which is connected to the bottom wall of the groove and the end face of the guide 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 part of the side of the guide 221 facing the water inlet 11.

[0124] In one embodiment, as shown in FIGS. 2-12, the water outlet control structure 2 further comprises a reset assembly 23 arranged in the main body 1 and between the first control assembly 21 and the second control assembly 22. The reset assembly 23 can drive the second control assembly 22 to rotate relative to the main body 1 for resetting the second control assembly 22.

[0125] Under the driving of the reset assembly 23, the rotation resetting of the second control assembly 22 can be realized to ensure the accuracy and reliability of the water outlet in the quantitative water outlet mode.

[0126] Specifically, the reset assembly 23 comprises an impeller set 231 and a speed reduction gear set 232. The speed reduction gear set 232 is arranged between the impeller set 231 and the second control assembly 22, and the impeller set 231 can drive the second control assembly 22 to rotate through the speed reduction gear set 232.

[0127] Under the action of water pressure, the impeller set 231 rotates counterclockwise relative to the main body 1, and the impeller 2312 drives the speed reduction gear set 232 to rotate. The speed reduction gear set 232 plays a role of speed reduction to avoid the situation that the water outlet time in the quantitative water outlet mode is relatively short due to too fast water flow speed. The speed reduction gear set 232 drives the second control assembly 22 to rotate counterclockwise. During the rotation of the guide 221, the top rod 211 moves slowly upward along the first sub-track 22121 to the first guide track 2211 corresponding to the closed position under the elastic restoring force of the first reset member 213, and the second end 2122 is blocked in the pressure relief hole 511 to stop water outlet.

[0128] Specifically, as shown in FIGS. 2-12, the impeller set 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 arranged on the impeller box 2311, the top rod 211 is arranged in the second guide through hole and is in sliding fit with the second guide through hole, thereby playing a guiding role and improving the alignment accuracy of the top rod 211 and the pressure relief hole 511.

[0129] Specifically, as shown in FIGS. 2-12, 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 set 231 is connected to the first gear 2321, the first gear 2321 and the second gear 2322 are engaged, the second gear 2322 and the third gear 2323 are engaged, the third gear 2323 and the fourth gear 2324 are engaged, and the fourth gear 2324 is connected to the guide 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 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 arranged in the plurality of second gears 2322 or the plurality of third gears 2323 to form different gear combinations.

[0130] In one embodiment, as shown in FIG. 10, the water outlet control mechanism further includes a limiting structure 3 arranged between the reset assembly 23 and the first control assembly 21 for limiting the first control assembly 21 and the reset assembly 23, and for locking the water outlet control structure 2 in the non-quantitative water outlet mode.

[0131] For example, the top rod 211 of the first control assembly 21 is provided with a limiting block 31, and the impeller 2312 is provided with a raised rib 32, and adjacent two raised ribs 32 form a limiting groove. When the top rod 211 is in the highest position, the limiting block 31 and the raised rib 32 are at the same height, the limiting block 31 prevents the rotation of the impeller 2312, the guide 221 cannot rotate, and the top rod 211 cannot be reset, thereby ensuring the stability of the non-quantitative water outlet mode.

[0132] In one embodiment, as shown in FIGS. 2, 14-15, the water outlet control structure 2 further includes a damper 24 arranged between the second control assembly 22 and the reset assembly 23, so that the rotating force of the reset assembly 23 can be transmitted to the second control assembly 22 in one direction through the damper 24.

[0133] In this way, when the user mode switches the rotating rod 222, the rotating rod 222 drives the guide 221 to rotate, but does not drive the gear set 232 and the impeller set 231 to rotate, but when in the quantitative mode, with the increase of water pressure, the rotating force of the reset assembly 23 can be transmitted to the second control assembly 22 through the damper 24 in one direction, for resetting the guide 221, for closing the quantitative water mode.

[0134] In one embodiment, the damper 24 comprises a gasket 241 and a second reset member 242, the second reset member 242, the gasket 241 and the reset assembly 23 are stacked, and the second control assembly 22 penetrates the gasket 241 and the second reset member 242 and abuts against the second reset member 242.

[0135] Wherein, the second reset member 242 can be selected as a disc spring, the gasket 241 can be selected as a wear-resistant gasket, the rotating rod 222 and the fourth gear 2324 can rotate relative to each other, but there is a frictional force between them. By setting the second reset member 242 and the wear-resistant gasket 241 between the rotating rod 222 and the fourth gear 2324, and using the stainless steel pad 240 and the shaft shoulder of the rotating rod 222 to fix and compress the second reset member 242. When the rotating rod 222 is switched to the quantitative water mode, the rotating rod 222 is rotated, and since the fourth gear 2324 is engaged with the other gears of the gear set 232, the fourth gear 2324 cannot rotate under the action of the gear set 232, and the rotating rod 222 overcomes the frictional force between the rotating rod 222 and the fourth gear 2324 to rotate. In the quantitative water mode, the impeller set 231 drives the gear set 232 to rotate, and with the rotation of the fourth gear 2324, the fourth gear 2324 drives the guide 221 and the rotating rod 222 to reset under the action of the frictional force.

[0136] In one embodiment, as shown in FIGS. 2, 6 and 7, the second control assembly 22 further comprises a handle 223, a snap spring 224 and a sealing ring 225, the rotating rod 222 penetrates the handle 223 and is fixed by a nut 226, and the handle 223 is used to facilitate the user to operate the rotating rod 222. The snap spring 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 for resetting 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.

[0137] In one embodiment, the static friction between the second control assembly 22 and the second reset member 242 is greater than the resistance friction of the second control assembly 22 relative to the main body 1.

[0138] That is, the static friction force between the shaft shoulder of the rotating rod 222 and the second reset member 242 needs to be greater than the friction force between the rotating rod 222 and the end cover, the sealing ring 225, the snap spring 224, etc. By using the static friction force, the reset assembly 23 drives the rotating rod 222 and the guide 221 through the gasket 241 and the second reset member 242, and the rotating rod 222 does not drive the second reset member 242 during mode switching, thereby ensuring the reliability of mode switching.

[0139] The embodiment also provides a water outlet device including the water outlet control mechanism. The water outlet control mechanism 2 can be used to freely switch between the quantitative water outlet mode and the non-quantitative water outlet mode, the user can conveniently switch modes during use, and the user experience is improved. Meanwhile, the main body 1 is provided with the water inlet 11 and the 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 the need to increase additional water inlets 11 or water outlets 12, thereby saving production manufacturing costs.

[0140] The embodiment also provides a water outlet control mechanism, as shown in FIGS. 1-15. 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. The water outlet control structure 2 includes a first control assembly 21, a second control assembly 22, a reset assembly 23, and a damper 24. The second control assembly 22 is configured to rotate relative to the main body 1 and drive the first control assembly 21 to move along the axial direction of the main body 1, so as to selectively connect the water inlet 11 and the water outlet 12, and open and close the quantitative water outlet mode. The reset assembly 23 is arranged between the first control assembly 21 and the second control assembly 22. The reset assembly 23 can drive the second control assembly 22 to rotate relative to the main body 1, and reset the second control assembly 22. The damper 24 is arranged between the second control assembly 22 and the reset assembly 23, so that the rotation force of the reset assembly 23 can be transmitted to the second control assembly 22 in one direction through the damper 24.

[0141] When the second control assembly 22 rotates relative to the main body 1 and drives the first control assembly 21 to move along 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 misaligned and do not block the pressure relief hole 511. The water flowing out of the pilot hole 420 can enter the pilot seat 51, 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. The water outlet control mechanism is in the quantitative water outlet state.

[0142] When the second control assembly 22 rotates relative to the main body 1 and drives the first control assembly 21 to move along the axial direction of the main body 1, the water inlet 11 and the water outlet 12 are communicated with each other. That is, the first control assembly 21 blocks 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-off mode or used for ending the quantitative water discharge mode, and more accurately controls the water discharge amount of the quantitative water discharge mode.

[0143] The reset assembly 23 can drive the second control assembly 22 to rotate relative to the main body 1. Under the driving of the reset assembly 23, the rotation reset of the second control assembly 22 can be realized, thereby ensuring the accuracy and reliability of the quantitative water discharge mode.

[0144] The rotation force of the reset assembly 23 can be unidirectionally transmitted to the second control assembly 22 through the damper 24. In this way, when the user mode switching rotary rod 222 is rotated, the rotary rod 222 drives the guide piece 221 to rotate, but does not drive the speed reduction gear set 232 and the impeller set 231 to rotate. However, when in the quantitative mode, as the water pressure increases, the rotation force of the reset assembly 23 can be unidirectionally transmitted to the second control assembly 22 through the damper 24, for resetting the guide piece 221 and closing the quantitative water discharge mode.

[0145] Embodiment Two

[0146] This embodiment is similar to Embodiment One, and the only difference is the specific structural details of the control end 212, the guide piece 221 and the damper 24.

[0147] As shown in FIGS. 16-21, 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 is one. The first end 2121 is arranged through the pressure relief hole 511 and gap-fitted with the pressure relief hole 511, and the second end 2122 is arranged through the pressure relief hole 511 and interference-fitted with the pressure relief hole 511.

[0148] The guide piece 221 provided in this embodiment has a first guide track 2211 and a second guide track 2212. The rotary rod 222 drives the guide piece 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, for switching between the water discharge mode and the water-off mode. The water discharge mode has the quantitative water discharge mode and the non-quantitative water discharge mode.

[0149] Exemplarily, the first guide track 2211 and the second guide track 2212 are continuous structures provided on the guide member 221, and the central angle of the first guide track 2211 is smaller than that of the second guide track 2212; when the rotating rod 222 abuts against the first guide track 2211, the water outlet control structure 2 is in the water-off mode; when the rotating rod 222 abuts against the second guide track 2212, the water outlet control structure 2 is in the quantitative water outlet mode or the non-quantitative water outlet mode.

[0150] Specifically, the guide member 221 is provided with a groove on the side facing the top rod 211, and the groove can be a V-shaped structure. The side wall of the groove is a slope wall structure, which facilitates the sliding of the top rod 211 into or out of the groove. The groove wall forms the first guide track 2211, and the end face of the side of the guide member 221 not provided with the groove forms the second guide track 2212.

[0151] When the top rod 211 is located in 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. Therefore, the second end 2122 located at the lowermost end of the top rod 211 penetrates the pressure relief hole 511 and blocks the pressure relief hole 511, and at this time, the water outlet control structure 2 is in the water-off mode. When the top rod 211 is located in 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. Therefore, the first end 2121 located at the upper end of the top rod 211 penetrates the pressure relief hole 511, and the first end 2121 and the pressure relief hole 511 have a gap therebetween, and at this time, the water outlet control structure 2 is in the water outlet mode, i.e., the quantitative water outlet mode or the non-quantitative water outlet mode.

[0152] As shown in FIGS. 22-24, the damper 24 provided in the embodiment includes a clutch 243, which is arranged between the second control assembly 22 and the reset assembly 23, and is used for selectively connecting the second control assembly 22 to the reset assembly 23.

[0153] When the clutch 243 is in the disengaged state, the second control assembly 22 and the reset assembly 23 are disconnected, and as the water pressure increases, the reset assembly 23 cannot reset the guide member 221 and the rotating rod 222 of the second control assembly 22, thereby realizing the non-quantitative water outlet mode. When the clutch 243 is in the engaged state, the second control assembly 22 and the reset assembly 23 are connected, and as the water pressure increases, the reset assembly 23 resets the guide member 221 and the rotating rod 222 of the second control assembly 22, thereby realizing the quantitative water outlet mode and achieving water outlet control.

[0154] 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 the two water outlet modes, i.e., the quantitative water outlet mode and the non-quantitative water outlet mode.

[0155] Specifically, as shown in Figures 22-24, the clutch 243 comprises a connecting seat 2433, a pawl 2431 and a buckle 2432, one of which is arranged on the second control assembly 22, and the other is arranged on the reset assembly 23; the connecting seat 2433 is provided with a first guide slope 24331, and the second control assembly 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 in sliding fit, so that the pawl 2431 and the buckle 2432 are selectively clamped.

[0156] When the user needs to switch to the non-quantitative water outlet mode, the rotating rod 222 is rotated, the rotating rod 222 drives the guide 221, the guide 221 is guided by the rotating rod 222, the second guide slope 2213 of the guide 221 is lifted along the first guide slope 24331 of the connecting seat 2433, so that the pawl 2431 and the buckle 2432 connected with the guide 221 and the reset assembly 23 respectively are separated, at this time, the impeller set 231 and the reduction gear set 232 cannot reset the guide 221 and the rotating rod 222 when rotating, realizing the non-quantitative water outlet. When mode switching is needed, the rotating rod 222 is rotated, under the action of the elasticity of the first reset member 213, the pawl 2431 and the buckle 2432 are re-clamped, the guide 221 and the reset assembly 23 are re-connected, realizing the water-off mode and the quantitative water outlet mode.
