Description

Technical Field

[0001] This application relates to the field of water outlet equipment technology, and in particular to a water outlet mode switching mechanism and a water outlet device. Background Technology

[0002] Faucets and other water dispensing devices are essential basic equipment in people's daily lives. To adapt to different usage scenarios and needs, most water dispensing devices support multiple water dispensing modes, allowing users to choose flexibly as needed, thereby improving ease of use and cleaning efficiency, making daily water use more comfortable and water-saving.

[0003] In related technologies, button-type switching mechanisms include a switching button and a water distribution plate. The switching button drives the water distribution plate to rotate via a transmission component, realizing the switching process of the water output mode. However, the transmission component of the current switching mechanism has a complex structure, which not only easily leads to problems such as mechanism jamming and irregular operation, resulting in an increased product failure rate, but also results in the need for excessive switching force, causing slow mechanism response speed, lagging adjustment and control, and a poor user experience. Summary of the Invention

[0004] Therefore, it is necessary to provide a water outlet mode switching mechanism and water outlet device to address the problems of complex structure, easy failure and slow response speed of water outlet mode switching mechanism.

[0005] A water outlet mode switching mechanism is applied to a water outlet device, the water outlet device including a housing, the water outlet side of the housing being provided with at least three water outlet structures, each water outlet structure corresponding to a water outlet mode; the water outlet mode switching mechanism includes:

[0006] A first waterway is provided inside the housing, and an operating component is movably provided in the first waterway;

[0007] The switching component, at least part of which is fitted inside the first waterway, is movably disposed relative to the first waterway, and a water-dividing component is provided at the end of the switching component facing the water outlet structure.

[0008] A transmission assembly is disposed in the first waterway, and the transmission assembly is connected to the operating component;

[0009] The switching component has a first position and a second position distributed along the axial direction. When the water outlet device is discharging water, the switching component is in the first position, and when the water outlet device is shut off, the switching component is in the second position. When the switching component is in the first position, it is connected to the transmission assembly. The operating component can drive the switching component and the water distribution component to rotate around the axial direction through the transmission assembly, so that the water distribution component sequentially cooperates with each of the water outlet structures to switch the water outlet mode. When the switching component moves from the first position to the second position and is in the second position, it disengages from the transmission assembly.

[0010] In one embodiment of this application, the water outlet mode includes a default water outlet mode; the water outlet mode switching structure further includes a reset mechanism, which is disposed in the first water channel and the water distribution component. When the switching component moves from the first position to the second position, the switching component and the water distribution component rotate around the axis through the reset mechanism, so that the water distribution component cooperates with the water outlet structure corresponding to the default water outlet mode.

[0011] In one embodiment of this application, the reset mechanism includes a reset member and a reset guide surface. One of the reset member and the reset guide surface is disposed in the water distribution component, and the other is disposed in the first water channel. When the switching component moves from the first position to the second position, the reset member abuts against the reset guide surface and slides along the reset guide surface. When the switching component reaches the second position, the water distribution component cooperates with the water outlet structure corresponding to the default water outlet mode.

[0012] In one embodiment of this application, the reset mechanism further includes a limiting groove, which is disposed on the switching component or the first waterway along with the reset guide surface. When the switching component reaches the second position, the end of the reset component is inserted into the limiting groove.

[0013] In one embodiment of this application, the water outlet device further includes a water outlet mesh group disposed on the water outlet side of the housing, and the water outlet structure disposed on the water outlet mesh group; the water outlet mode switching mechanism further includes an elastic reset component disposed between the water outlet mesh group and the switching component, and during the closing process of the water outlet device, the elastic reset component is used to drive the switching component to move from the first position to the second position.

[0014] In one embodiment of this application, the elastic reset component includes a first elastic component, and the switching component is provided with an assembly groove on the side facing the water outlet network group. One end of the first elastic component is placed in the assembly groove, and the other end abuts against the water outlet network group.

[0015] In one embodiment of this application, the elastic reset assembly further includes a connector disposed within the assembly groove, the first elastic component being sleeved outside the connector, and the end face of the connector facing away from the first elastic component being in movable contact with the bottom of the assembly groove.

[0016] In one embodiment of this application, the diameter of the water-dividing component is larger than the diameter of the switching component. During the opening of the water outlet device, water flow can act on the side of the water-dividing component facing away from the water outlet structure through the first water channel, thereby driving the switching component to move from the second position to the first position.

[0017] In one embodiment of this application, a seal is provided between the portion of the switching component placed inside the first waterway and the first waterway.

[0018] In one embodiment of this application, the transmission assembly includes a first transmission wheel and a second transmission wheel coaxially arranged. The first transmission wheel and the second transmission wheel have a first engagement structure and a second engagement structure. In a first direction around the axial direction, the second transmission wheel is linked with the first transmission wheel through the first engagement structure. In a second direction around the axial direction, the second transmission wheel is axially disengaged from the first transmission wheel through the second engagement structure. The first direction is opposite to the second direction. A portion of the structure of the operating component meshes with the first transmission wheel. The operating component has a first state and a second state.

[0019] When the switching component is in the first position, the switching component is connected to the second transmission wheel. During the movement of the operating component from the first state to the second state, the operating component drives the first transmission wheel and the second transmission wheel to rotate in the first direction by a preset angle. The preset angle matches the central angle corresponding to the adjacent water outlet structure. During the movement of the operating component from the second state to the first state, the operating component drives the first transmission wheel to rotate in the second direction, and the first transmission wheel and the second transmission wheel disengage axially.

[0020] In one embodiment of this application, a first protrusion is provided on the side of the first transmission wheel facing the second transmission wheel, and a second protrusion is provided on the side of the second transmission wheel facing the first transmission wheel. The first protrusion has a first mating surface and a first inclined surface, and the second protrusion has a second mating surface and a second inclined surface. The first mating surface and the second mating surface constitute the first mating structure, and the first inclined surface and the second inclined surface constitute the second mating structure.

[0021] When the operating component drives the first transmission wheel to rotate in the first direction, the first mating surface abuts against the second mating surface, thereby driving the second transmission wheel to rotate in the first direction;

[0022] When the operating component drives the first transmission wheel to rotate in the second direction, the first inclined surface slides into contact with the second inclined surface, and the second transmission wheel disengages from the first transmission wheel axially.

[0023] In one embodiment of this application, when the switching component is in the first position, the end of the switching component away from the water distribution component is connected to the second transmission wheel via a snap-fit ​​structure, the snap-fit ​​structure being used to limit the switching component and the second transmission wheel in the circumferential direction.

[0024] In one embodiment of this application, the snap-fit ​​structure includes a protrusion and a slot, one of which is disposed at the end of the switching component away from the water distribution component, and the other is disposed on the inner wall of the second transmission wheel. The protrusion can be inserted into or disengaged from the slot axially.

[0025] A water outlet device includes a housing and a water outlet mode switching mechanism as described above. The water outlet mode switching mechanism is disposed inside the housing and is used to switch the water outlet mode of the water outlet device.

[0026] In one embodiment of this application, the water outlet device includes a pull-out faucet.

[0027] The aforementioned water outlet mode switching mechanism includes a first water channel, a switching component, and a transmission assembly. When the switching component is in the first position, it is connected to the transmission assembly. The operating component can drive the switching component and the water distribution component to rotate axially via the transmission assembly, causing the water distribution component to sequentially engage with each water outlet structure to switch the water outlet mode. When the switching component moves from the first position to the second position and is in the second position, it disengages from the transmission assembly. This water outlet mode switching mechanism employs a clutch structure design for the switching component and the transmission assembly, simplifying the overall mechanism construction. The switching component is only connected to the transmission assembly when it is in the first position; otherwise, they are not connected. The position of the switching component is related to the water output of the water outlet device. The switching component needs to move back and forth between the first position and the second position. When the switching component is in the first position, it is connected to the transmission component, which can easily realize the function of switching the water output mode. When it is not necessary to switch the water output mode, the switching component is disengaged from the transmission component. At this time, the transmission component will not move axially synchronously with the switching component, which significantly simplifies the structure that needs to move axially, helps to reduce the failure rate of the mechanism, greatly reduces the motion resistance of the switching component and the water distribution component during the movement, and reduces the driving torque required for the switching component and the water distribution component to move axially, thereby significantly improving the response speed of the mechanism, making the mechanism run more smoothly and with high reliability.

[0028] The aforementioned water outlet device, including the aforementioned water outlet mode switching mechanism, has the same beneficial effects, which will not be elaborated here. Attached Figure Description

[0066] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0067] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0068] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0069] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0070] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0071] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0072] See Figures 1-15As shown, an embodiment of this application provides a water outlet mode switching mechanism applied to a water outlet device. The water outlet device includes a housing 100, and the water outlet side of the housing 100 is provided with at least three water outlet structures, each corresponding to a water outlet mode. The water outlet mode switching mechanism includes: a first water channel 1, a switching component 3, and a transmission assembly. The first water channel 1 is disposed within the housing 100, and an operating component 2 is movably disposed within the first water channel 1. At least a portion of the switching component 3 is fitted within the first water channel 1, and the switching component 3 is movably disposed relative to the first water channel 1. A water-dividing component 4 is disposed at the end of the switching component 3 facing the water outlet structure. The transmission assembly... The component is installed in the first waterway 1, and the transmission assembly is connected to the operating component 2. The switching component 3 has a first position and a second position distributed along the axial direction. When the water outlet device is discharging water, the switching component 3 is in the first position, and when the water outlet device is shut off, the switching component 3 is in the second position. When the switching component 3 is in the first position, the switching component 3 is connected to the transmission assembly. The operating component 2 can drive the switching component 3 and the water distribution component 4 to rotate around the axial direction through the transmission assembly, so that the water distribution component 4 cooperates with each water outlet structure in sequence to switch the water outlet mode. When the switching component 3 moves from the first position to the second position and is in the second position, the switching component 3 is disengaged from the transmission assembly.

[0073] This water outlet mode switching mechanism employs a clutch-like structure design between the switching component 3 and the transmission assembly, simplifying the overall structure. The switching component 3 is only connected to the transmission assembly when it is in the first position; otherwise, they are not connected. The position of the switching component 3 depends on the water outlet status of the device. It needs to reciprocate between the first and second positions. When in the first position, it connects to the transmission assembly, facilitating easy switching of the water outlet mode. When switching is not required, it disengages from the transmission assembly, preventing the transmission assembly from moving axially synchronously with it. This significantly simplifies the axial movement structure, reducing the failure rate. The axial movement resistance of the switching component 3 and the water distribution component 4 is greatly reduced, as is the driving torque required for their axial movement. This significantly improves the mechanism's response speed, resulting in smoother operation and higher reliability.

[0074] The water outlet mode switching mechanism of this application is applied to a water outlet device, which can be a faucet, such as a pull-out faucet. This water outlet device has multiple water outlet modes, such as: gentle water mode, spray mode, direct spray mode, powerful rinsing mode, and atomization mode. The water outlet mode switching mechanism of this application is used to switch the water outlet mode of the water outlet device to meet different user needs.

[0075] Typically, a water dispensing device includes a housing 100, which is the main structure of the device and is used to install or support other mechanisms within the device. The housing 100 can be made of materials such as metal, alloy, or plastic. The housing 100 has an inlet side and an outlet side. Generally speaking, water enters the housing 100 from the inlet side and then flows out from the outlet side for user use. To provide multiple dispensing modes, at least three dispensing structures are provided on the outlet side of the housing 100, each corresponding to a different dispensing mode, giving the device at least three dispensing modes. For example, the water dispensing device can have three, four, or five dispensing modes.

[0076] The water outlet mode switching mechanism of this application is used to switch the water outlet mode in a unidirectional and cyclical manner. For example, the water outlet structure has four water outlet modes, namely the first mode, the second mode, the third mode and the fourth mode. The water outlet mode switching mechanism switches each water outlet mode in a unidirectional and cyclical manner, such as: the first mode - the second mode - the third mode - the fourth mode - the first mode... and so on.

[0077] The water outlet mode switching mechanism includes a first water channel 1, which is installed inside the housing 100. The first water channel 1 is one of the main structures in the water outlet device. The first water channel 1 is mainly used for water flow and for guiding the water flow in the process. Specifically, the first water channel 1 is the front water channel.

[0078] See Figure 1 As shown, the first waterway 1 is movably equipped with an operating component 2, which allows the user to switch and adjust the water outlet mode. In one embodiment, the operating component 2 has an operating end 202 connected to a button 17. At least a portion of the button 17 is exposed outside the housing 100 for easy pressing by the user. Furthermore, the operating surface of the button 17 conforms to the shape of a human finger, improving operational comfort.

[0079] See Figures 3-4 As shown, the water outlet mode switching mechanism also includes a switching component 3 (or a center plug). At least a portion of the structure of the switching component 3 is fitted inside the first water channel 1, and the switching component 3 is movably configured relative to the first water channel 1. The switching component 3 is generally a long rod-shaped structure. Depending on the different structural requirements, all or part of the structure of the switching component 3 is fitted inside the first water channel 1. In one embodiment, the first water channel 1 has an assembly through hole. At least a portion of the structure of the switching component 3 passes through the assembly through hole and is coaxially configured with the assembly through hole. The movement of the switching component 3 relative to the first water channel 1 includes reciprocating movement along the axis and rotation around the axis, so as to realize the water outlet process and the water outlet mode switching process of the water outlet device.

[0080] See Figure 2As shown, a water-dividing component 4 is provided at the end of the switching component 3 facing the water outlet structure. The water-dividing component 4 is linked to the switching component 3, meaning that the switching component 3 and the water-dividing component 4 can move back and forth along the axis or rotate around the axis synchronously. The water-dividing component 4 is used to cooperate with the water outlet structure on the water outlet side of the water outlet device to realize water outlet and the switching of water outlet mode. In one embodiment, the water-dividing component 4 is a water-dividing plate, and the center of the water-dividing component 4 is connected to one end of the switching component 3, so that the switching component 3 and the water-dividing component 4 are coaxially arranged. In one embodiment, the switching component 3 and the water-dividing component 4 are integrally formed to ensure the connection strength between the switching component 3 and the water-dividing component 4. In one embodiment, the switching component 3 and the water-dividing component 4 are separately formed and assembled and connected by a connecting structure, such as a threaded structure or a snap-fit ​​structure.

[0081] In one embodiment, on the water outlet side of the outer casing 100, the water outlet structures are distributed in a circumferential matrix. When switching water outlet modes, the water distribution component 4 and the switching component 3 rotate synchronously in one direction around the axial direction, so that the water distribution component 4 sequentially engages with each water outlet structure. For example, the water outlet device has four water outlet modes, namely the first mode, the second mode, the third mode, and the fourth mode. Correspondingly, there are four types of water outlet structures, namely the first water outlet structure, the second water outlet structure, the third water outlet structure, and the fourth water outlet structure. When switching water outlet modes, the water distribution component 4 and the switching component 3 rotate synchronously in one direction around the axial direction, and the water distribution component 4 sequentially and cyclically engages with the first water outlet structure, the second water outlet structure, the third water outlet structure, the fourth water outlet structure, the first water outlet structure, the second water outlet structure, and so on.

[0082] The water outlet mode switching mechanism also includes a transmission component, which is located in the first water channel 1 and connected to the operating component 2. The transmission component is used to transmit the operating action of the operating component 2 to the switching component 3 to realize the switching of the water outlet mode.

[0083] The switching component 3 has a first position and a second position, which are distributed axially. The switching component 3 reciprocates between the first position and the second position. The axial position of the switching component 3 is related to the state of the water outlet device, which includes water outlet and water shut-off. When the water outlet device is in the water outlet state, water flows out; when the water outlet device is in the water shut-off state, no water flows out. When the water outlet device is in the water outlet state, the switching component 3 is in the first position; when the water outlet device is in the water shut-off state, the switching component 3 is in the second position. Therefore, when the state of the water outlet device switches between water outlet and water shut-off, the switching component 3 is between the first position and the second position.

[0084] When the switching component 3 is in the first position, the switching component 3 is connected to the transmission component. At this time, if the user needs to switch the water outlet mode, he / she can operate the operating component 2. The operating component 2 can drive the switching component 3 and the water distribution component 4 to rotate around the axis through the transmission component, so that the water distribution component 4 can cooperate with each water outlet structure in sequence to realize the switching of the water outlet mode.

[0085] When the switching component 3 moves from the first position to the second position and is in the second position, there is no need to switch the water outlet mode. The switching component 3 is disengaged from the transmission component, and the transmission component will not move axially with the switching component 3. This significantly simplifies the structure of the water outlet mode switching mechanism that needs to move axially. The motion resistance of the switching component 3 and the water distribution component 4 during axial movement is greatly reduced, and the driving torque required for the switching component 3 and the water distribution component 4 to move axially is reduced, thereby significantly improving the mechanism's response speed.

[0086] In one embodiment of this application, the water outlet mode includes a default water outlet mode; the water outlet mode switching structure further includes a reset mechanism, which is disposed in the first water channel 1 and the water distribution component 4. When the switching component 3 moves from the first position to the second position, the switching component 3 and the water distribution component 4 rotate around the axis through the reset mechanism, so that the water distribution component 4 cooperates with the water outlet structure corresponding to the default water outlet mode.

[0087] The water dispensing device has at least three water dispensing modes, one of which is set as the default water dispensing mode, for example, the soft water mode is set as the default water dispensing mode. In one embodiment, after the user finishes using the water dispensing device and turns off the water, the water dispensing device will automatically revert to the default water dispensing mode.

[0088] The water outlet mode switching structure also includes a reset mechanism, which is used to automatically restore the water outlet device to the default water outlet mode after the water is turned off. The reset mechanism is located in the first water channel 1 and the water distribution component 4. When the switching component 3 moves from the first position to the second position, the switching component 3 and the water distribution component 4 rotate around the axis through the reset mechanism, so that the water distribution component 4 cooperates with the water outlet structure corresponding to the default water outlet mode, and the water outlet mode of the water outlet device is restored to the default water outlet mode.

[0089] In one embodiment of this application, the reset mechanism includes a reset member 501 and a reset guide surface 502. One of the reset member 501 and the reset guide surface 502 is disposed in the water distribution component 4, and the other is disposed in the first water channel 1. When the switching component 3 moves from the first position to the second position, the reset member 501 abuts against the reset guide surface 502 and slides along the reset guide surface 502. When the switching component 3 reaches the second position, the water distribution component 4 cooperates with the water outlet structure corresponding to the default water outlet mode.

[0090] See Figure 2 , Figures 8-9As shown, in one embodiment, a reset member 501 is disposed on the side of the water distribution component 4 connected to the switching component 3, and two reset members 501 are provided. Each reset member 501 has a rod-shaped structure, with one end connected to the water distribution component 4 and the other end serving as the action end, used to abut against the reset guide surface 502. The extending direction of the reset member 501 is consistent with the axial direction of the switching component 3. In one embodiment, the two reset members 501 are symmetrically arranged relative to the axis of the first water channel 1.

[0091] See Figures 7-9 As shown, a reset guide surface 502 is disposed in the first waterway 1. A central column 105 is disposed at the center of the side of the first waterway 1 facing the water outlet. The interior of the central column 105 is an assembly through hole. The switching component 3 is adapted to pass through the assembly through hole of the central column 105 and can move axially within the assembly through hole. The reset guide surface 502 is disposed outside the central column 105 and arranged circumferentially around the central column 105. Specifically, the reset guide surface 502 includes a first guide surface 5021, a second guide surface 5022, a third guide surface 5023, and a fourth guide surface 5024, so as to... Figure 9 Taking a perspective example, the first guide surface 5021, the second guide surface 5022, the third guide surface 5023, and the fourth guide surface 5024 are arranged in a clockwise direction. The first guide surface 5021, the second guide surface 5022, the third guide surface 5023, and the fourth guide surface 5024 are arranged in a spiral pattern. The spiral direction of the first guide surface 5021 and the third guide surface 5023 is the same, and the spiral direction of the second guide surface 5022 and the fourth guide surface 5024 is the same.

[0092] See Figure 9 As shown, in one embodiment, the two reset members 501 cooperate with the first guide surface 5021 and the third guide surface 5023 respectively. During the process of the switching component 3 moving from the first position to the second position, the working ends of the two reset members 501 abut against and slide against the first guide surface 5021 and the third guide surface 5023 respectively. The sliding direction of the two reset members 501 is clockwise as shown by the arrow. When the switching component 3 reaches the second position, the water distribution component 4 cooperates with the water outlet structure corresponding to the default water outlet mode.

[0093] In one embodiment of this application, the reset mechanism further includes a limiting groove 503. The limiting groove 503 and the reset guide surface 502 are simultaneously disposed on the switching component 3 or the first waterway 1. When the switching component 3 reaches the second position, the end of the reset component 501 is inserted into the limiting groove 503.

[0094] See Figures 9-10As shown, the reset mechanism also includes a limiting groove 503, and the setting position and number of the limiting groove 503 match the setting position and number of the reset component 501. The limiting groove 503 and the reset guide surface 502 are simultaneously provided in the switching component 3 or the first waterway 1.

[0095] In one embodiment, the limiting groove 503 and the reset guide surface 502 are simultaneously disposed in the first waterway 1. Specifically, the reset guide surface 502 includes a first guide surface 5021, a second guide surface 5022, a third guide surface 5023, and a fourth guide surface 5024. Two limiting grooves 503 are provided, one of which is disposed at the intersection of the first guide surface 5021 and the second guide surface 5022, and the other is disposed at the intersection of the third guide surface 5023 and the fourth guide surface 5024. The shape and size of the limiting groove 503 match the shape and size of the actuating end of the reset member 501.

[0096] When the switching component 3 reaches the second position, the active end of the reset component 501 is inserted into the limiting groove 503. The switching component 3 and the first water channel 1 are at the upper limit in the circumferential direction. The switching component 3 and the water distribution component 4 cannot continue to rotate around the axial direction. At this time, the water distribution component 4 just matches the water outlet structure corresponding to the default water outlet mode, realizing the function of restoring the default water outlet mode.

[0097] In one embodiment of this application, the water outlet device further includes a water outlet network group 200, which is disposed on the water outlet side of the housing 100, and the water outlet structure is disposed on the water outlet network group 200; the water outlet mode switching mechanism further includes an elastic reset component, which is disposed between the water outlet network group 200 and the switching component 3. During the closing process of the water outlet device, the elastic reset component is used to drive the switching component 3 to move from the first position to the second position.

[0098] See Figures 3-4 As shown, the water outlet device also includes a water outlet mesh group 200, which is located on the water outlet side of the outer casing 100. The water outlet mesh group 200 is mainly used to divert, rectify, and filter the water flow to form a uniform and stable water outlet.

[0099] The water outlet structure of the water outlet device is located in the water outlet network assembly 200. Specifically, the side of the water outlet network assembly 200 facing the switching component 3 is a water outlet panel. Each water outlet structure has two water outlets on the water outlet panel, and the two water outlets are symmetrically arranged with respect to the center of the water outlet panel. Accordingly, see [reference needed]. Figure 6As shown, the water distribution component 4 is provided with two channels 401. The two channels 401 are symmetrically arranged with respect to the axis of the water distribution component 4. When the two channels 401 are respectively connected to the two water outlets of a certain water outlet structure, the water outlet mode of the water outlet device is the water outlet mode corresponding to that water outlet structure. Furthermore, when the channels 401 are connected to the water outlets, they are relatively sealed to prevent water leakage.

[0100] The water outlet mode switching mechanism also includes an elastic reset component, which is disposed between the water outlet network group 200 and the switching component 3. During the water outlet device shutdown process, the elastic reset component is used to drive the switching component 3 to move from the first position to the second position. In one embodiment, see [reference needed]. Figure 3 As shown, when the water outlet device is opened, the water flow through the first water channel 1 pushes the water distribution component 4 and the switching component 3 toward the direction closer to the water outlet network group 200, and the water flow direction is as follows. Figure 3 As indicated by the middle arrow, when the water outlet device is closed, the water flow gradually decreases. When the elastic force of the elastic reset component exceeds the force of the water flow, the switching component 3 and the water distribution component 4 move from the first position to the second position. It is understandable that during the opening of the water outlet device, the water flow needs to overcome the elastic force of the elastic reset component to push the switching component 3 and the water distribution component 4 towards the direction closer to the water outlet network 200.

[0101] In one embodiment of this application, the elastic reset component includes a first elastic component 6. The switching component 3 is provided with an assembly groove 301 on the side facing the water outlet network group 200. One end of the first elastic component 6 is placed in the assembly groove 301, and the other end abuts against the water outlet network group 200.

[0102] The elastic reset assembly includes a first elastic component 6, which abuts against the switching component 3 and the water outlet network group 200. In one embodiment, the switching component 3 is provided with an assembly groove 301 on the side facing the water outlet network group 200, the opening of the assembly groove 301 facing the water outlet network group 200, one end of the first elastic component 6 is placed in the assembly groove 301, and the other end abuts against the water outlet network group 200.

[0103] Specifically, a second positioning post 20 is provided at the water outlet panel of the water outlet network assembly 200. One end of the first elastic component 6 is placed in the assembly groove 301, and the other end is sleeved on the second positioning post 20 and abuts against the water outlet panel to position the first elastic component 6 and improve structural reliability. Furthermore, the outer diameter of the second positioning post 20 is smaller than the inner diameter of the assembly groove 301. When the switching component 3 reaches the first position, the second positioning post 20 can enter the assembly groove 301 to save axial space.

[0104] In one embodiment, the first elastic member 6 is a spring.

[0105] In one embodiment of this application, the elastic reset assembly further includes a connector 7, which is disposed in the assembly groove 301. The first elastic component 6 is sleeved on the outside of the connector 7, and the end face of the connector 7 facing away from the first elastic component 6 is in active contact with the bottom of the assembly groove 301.

[0106] See Figure 3 and Figure 4 As shown, the elastic reset assembly also includes a connector 7, or rotating pin. The connector 7 has a columnar structure and is disposed within the assembly groove 301. The first elastic component 6 is sleeved on the outside of the connector 7. The connector 7 is movably disposed within the assembly groove 301, such that the end face of the connector 7 facing away from the first elastic component 6 makes movable contact with the bottom of the assembly groove 301. Since the switching component 3 needs to rotate around its axis during operation, the rotation of the switching component 3 will not cause the first elastic component 6 to rotate, thus preventing the first elastic component 6 from twisting under prolonged use, which would affect the rotation of the switching component 3 to its final position and thus affect the switching of the water outlet mode.

[0107] In one embodiment, the end face of the connector 7 facing away from the first elastic member 6 is an arc-shaped surface, the bottom of the assembly groove 301 is a flat surface, and the connector 7 and the bottom of the assembly groove 301 are in point-to-surface contact to reduce the friction between the connector 7 and the switching member 3, thereby further reducing the rotational resistance of the switching member 3.

[0108] In one embodiment of this application, the diameter of the water-dividing component 4 is larger than the diameter of the switching component 3. During the opening of the water outlet device, the water flow can act on the side of the water-dividing component 4 facing away from the water outlet structure through the first water channel 1, so as to drive the switching component 3 to move from the second position to the first position.

[0109] See Figures 2-3 As shown, the water distribution component 4 has a disc-shaped structure, and its diameter is significantly larger than that of the switching component 3. The side of the water distribution component 4 facing away from the water outlet structure has a large working surface, and the first water channel 1 has a water passage hole. During the opening of the water outlet device, water flow can act on the side of the water distribution component 4 facing away from the water outlet structure through the first water channel 1, thereby pushing the switching component 3 from the second position to the first position, realizing the water outlet process of the water outlet device.

[0110] Since the only structures that need to move along the axial direction in the water outlet mode switching mechanism of this application are the switching component 3 and the water distribution component 4, and the side of the water distribution component 4 facing away from the water outlet structure has a large working surface, the opening force required by the mechanism is small. The switching component 3 and the water distribution component 4 can quickly open the water outlet under the action of water pressure. The water outlet device has a fast response speed and the water outlet process is fast and smooth.

[0111] In one embodiment of this application, a seal 8 is provided between the portion of the switching component 3 placed inside the first waterway 1 and the first waterway 1.

[0112] See Figure 3 As shown, a seal 8 is provided between the portion of the switching component 3 placed inside the first water channel 1 and the first water channel 1, and there is only one seal 8 to save product costs. In addition, while ensuring the seal between the switching component 3 and the first water channel 1, the influence of the seal 8 on the axial movement of the switching component 3 is reduced, the moving friction of the switching component 3 is reduced, and the movement process of the switching component 3 is made faster and smoother.

[0113] In one embodiment, the seal 8 is a Y-shaped sealing ring.

[0114] In one embodiment of this application, the transmission assembly includes a first transmission wheel 9 and a second transmission wheel 10 coaxially arranged. The first transmission wheel 9 and the second transmission wheel 10 have a first engagement structure and a second engagement structure. In a first direction around the axial direction, the second transmission wheel 10 is linked with the first transmission wheel 9 through the first engagement structure. In a second direction around the axial direction, the second transmission wheel 10 is axially disengaged from the first transmission wheel 9 through the second engagement structure. The first direction is opposite to the second direction. A portion of the structure of the operating component 2 is engaged with the first transmission wheel 9. The operating component 2 has a first state and a second state. When the switching component 3 is in the first position, the switching component 3 is connected to the second transmission wheel 10. During the movement of the operating component 2 from the first state to the second state, the operating component 2 drives the first transmission wheel 9 and the second transmission wheel 10 to rotate in the first direction by a preset angle. The preset angle matches the central angle corresponding to the adjacent water outlet structure. During the movement of the operating component 2 from the second state to the first state, the operating component 2 drives the first transmission wheel 9 to rotate in the second direction, and the first transmission wheel 9 and the second transmission wheel 10 are axially disengaged.

[0115] See Figures 10-13 As shown, the first waterway 1 has an operating component mounting groove 106 on the side facing away from the outlet, so as to... Figure 10 Taking a specific perspective, the opening of the operating component mounting slot 106 faces upwards. The upper part of the operating component 2 is the operating end 202, and the lower part is a forked structure, with one of the forked structures having a rack portion 201. The forked structure of the operating component 2 can be inserted into the operating component mounting slot 106 to achieve the installation of the operating component 2.

[0116] Furthermore, a first positioning post 101 is provided at the opening of the operating component mounting groove 106. The first positioning post 101 is used to sleeve the second elastic component 16. One end of the second elastic component 16 is sleeved on the first positioning post 101, and the other end is inserted into the operating end 202. After the user presses the operating component 2, the second elastic component 16 is used to apply an elastic restoring force to the operating component 2 so that the operating component 2 rebounds.

[0117] The transmission assembly includes a first transmission wheel 9 and a second transmission wheel 10, which are coaxially arranged. Specifically, a first mounting portion 102 and a second mounting portion 103 are provided on the side of the first waterway 1 facing away from the outlet side. The first mounting portion 102 and the second mounting portion 103 are coaxially arranged, and in the radial direction, the first mounting portion 102 is located outside the second mounting portion 103. The first transmission wheel 9 is sleeved on the first mounting portion 102, and the second transmission wheel 10 is sleeved on the second mounting portion 103. Furthermore, the second transmission wheel 10 can move within a small range axially on the second mounting portion 103.

[0118] The first transmission wheel 9 and the second transmission wheel 10 have a first mating structure and a second mating structure. In a first direction around the axial direction, the second transmission wheel 10 is linked with the first transmission wheel 9 through the first mating structure. The first direction is as follows: Figure 12 In the direction indicated by the middle arrow a, in the second direction around the axial direction, the second transmission wheel 10 is axially disengaged from the first transmission wheel 9 through the second mating structure, as shown in the second direction. Figure 13 The direction indicated by the middle arrow b is the opposite of the first direction to the second direction.

[0119] In one embodiment, the first transmission wheel 9 is a gear, meshing with the rack portion 201 of the operating component 2. When the user presses down on the operating component 2, the first transmission wheel 9 rotates in a first direction. When the operating component 2 rebounds under the action of the second elastic component 16, the first transmission wheel 9 rotates in a second direction. The second transmission wheel 10 is a ratchet. When the user presses down on the operating component 2, the first transmission wheel 9 rotates in the first direction, and the first transmission wheel 9 drives the second transmission wheel 10 to rotate in the first direction through a first engagement structure. When the operating component 2 rebounds under the action of the second elastic component 16, the first transmission wheel 9 rotates in the second direction, and the second transmission wheel 10 disengages axially from the first transmission wheel 9 through a second engagement structure, and the second transmission wheel 10 does not rotate with the first transmission wheel 9 in the second direction.

[0120] Specifically, the operating component 2 has a first state and a second state. The first state is the natural state in which the operating component 2 is not pressed down by the user (at this time, the second elastic component 16 is not compressed), while the second state is the pressed state in which the operating component 2 is pressed down by the user (at this time, the second elastic component 16 is compressed).

[0121] When the switching component 3 is in the first position, it is connected to the second transmission wheel 10. As the operating component 2 moves from the first state to the second state, it drives the first transmission wheel 9 and the second transmission wheel 10 to rotate in the first direction by a preset angle. The size of this preset angle matches the central angle corresponding to the adjacent water outlet structure. Simultaneously, the switching component 3 and the water distribution component 4 also rotate in the first direction by a preset angle, causing the channel 401 of the water distribution component 4 to engage with the outlet of the next water outlet structure, thereby switching the water outlet mode to the next mode position. Conversely, as the operating component 2 moves from the second state to the first state, it drives the first transmission wheel 9 to rotate in the second direction. The first transmission wheel 9 and the second transmission wheel 10 disengage axially, and the second transmission wheel 10, the switching component 3, and the water distribution component 4 do not rotate, thus maintaining the currently adjusted water outlet mode.

[0122] In one embodiment, the first waterway 1 is further provided with a claw mounting groove 104, and the transmission assembly also includes a claw 15. One end of the claw 15 is provided in the claw mounting groove 104, and the other end is adapted to engage with the external teeth of the second transmission wheel. The claw 15 is used to limit the second transmission wheel 10 in one direction, so that the second transmission wheel 10 can only rotate around the first direction and maintain the adjusted water outlet mode, thereby further improving the reliability of the structure.

[0123] In one embodiment of this application, a first protrusion 11 is provided on the side of the first transmission wheel 9 facing the second transmission wheel 10, and a second protrusion 12 is provided on the side of the second transmission wheel 10 facing the first transmission wheel 9. The first protrusion 11 has a first mating surface 1101 and a first inclined surface 1102, and the second protrusion 12 has a second mating surface 1201 and a second inclined surface 1202. The first mating surface 1101 and the second mating surface 1201 form a first mating structure, and the first inclined surface 1102 and the second inclined surface 1202 form a second mating structure. When the operating component 2 drives the first transmission wheel 9 to rotate in a first direction, the first mating surface 1101 abuts against the second mating surface 1201 to drive the second transmission wheel 10 to rotate in the first direction. When the operating component 2 drives the first transmission wheel 9 to rotate in a second direction, the first inclined surface 1102 slides into contact with the second inclined surface 1202, and the second transmission wheel 10 disengages from the first transmission wheel 9 axially.

[0124] See Figure 14 and Figure 15 As shown, a first protrusion 11 is provided on the side of the first transmission wheel 9 facing the second transmission wheel 10. The number of first protrusions 11 can be one, two, three, four, etc. The first protrusion 11 has a triangular prism-like structure and has a first mating surface 1101 and a first inclined surface 1102. The first mating surface 1101 and the first inclined surface 1102 are arranged at an angle or connected by a transition surface. In one embodiment, the first mating surface 1101 extends axially and is a straight plane.

[0125] Correspondingly, a second protrusion 12 is provided on the side of the second transmission wheel 10 facing the first transmission wheel 9. The number of second protrusions 12 can be four, eight, etc., and the number of first protrusions 11 and second protrusions 12 can be equal or unequal. It should be noted that the number of second protrusions 12 is related to the rotation angle required by the switching component 3 when switching the water outlet mode, and this angle is related to the central angle of the adjacent water outlet structure, which will not be elaborated in detail here. The second protrusion 12 has a second mating surface 1201 and a second inclined surface 1202, which are arranged at an included angle or connected by a transition surface. In one embodiment, the second mating surface 1201 extends axially and is a straight plane. The first mating surface 1101 and the second mating surface 1201 constitute a first mating structure, and the first inclined surface 1102 and the second inclined surface 1202 constitute a second mating structure.

[0126] When the operating component 2 drives the first transmission wheel 9 to rotate in the first direction, the first mating surface 1101 abuts against the second mating surface 1201, thereby driving the second transmission wheel 10 to rotate in the first direction. When the operating component 2 drives the first transmission wheel 9 to rotate in the second direction, the first inclined surface 1102 slides against the second inclined surface 1202, and the second transmission wheel 10 disengages from the first transmission wheel 9 axially. It should be noted that when the operating component 2 drives the first transmission wheel 9 to rotate in the second direction, the first inclined surface 1102 and the second inclined surface 1202 slide relative to each other, the first transmission wheel 9 is blocked by the first water channel 1 and cannot move axially, and the second transmission wheel 10 moves a distance away from the first transmission wheel 9 under the sliding action of the first inclined surface 1102 and the second inclined surface 1202, and the moving distance of the second transmission wheel 10 is related to the inclined surface length of the first inclined surface 1102 and the second inclined surface 1202.

[0127] In one embodiment of this application, when the switching component 3 is in the first position, the end of the switching component 3 away from the water distribution component 4 is connected to the second transmission wheel 10 through a snap-fit ​​structure. The snap-fit ​​structure is used to limit the switching component 3 and the second transmission wheel 10 in the circumferential direction.

[0128] See Figure 2 , Figures 5-6 As shown, the switching component 3 has a first position and a second position distributed along the axial direction. When the switching component 3 is in the first position, the end of the switching component 3 away from the water distribution component 4 is connected to the second transmission wheel 10 through a snap-fit ​​structure, so that the switching component 3 and the second transmission wheel 10 are in a circumferential upper limit position, and the switching component 3 can rotate synchronously with the second transmission wheel 10 in the circumferential direction. When the switching component 3 moves from the first position to the second position and when the switching component 3 is in the first position, the end of the switching component 3 away from the water distribution component 4 is disengaged from the second transmission wheel 10.

[0129] In one embodiment of this application, the snap-fit ​​structure includes a protrusion 1301 and a slot 1302. One of the protrusion 1301 and the slot 1302 is disposed at the end of the switching component 3 away from the water distribution component 4, and the other is disposed on the inner wall of the second transmission wheel 10. The protrusion 1301 can be inserted into or disengaged from the slot 1302 axially.

[0130] See Figure 2 , Figures 5-6 As shown, in one embodiment, the snap-fit ​​structure includes a protrusion 1301 and a slot 1302. The protrusion 1301, also called a rib, is disposed at the end of the switching component 3 away from the water distribution component 4, and at least one protrusion 1301 is provided. The number of protrusions 1301 is less than or equal to the number of slots 1302, such as one, two, three, four, etc. In one embodiment, at least two protrusions 1301 may be provided to ensure that the switching component 3 can reliably connect with the second transmission wheel 10 in the circumferential direction. In one embodiment, four protrusions 1301 are provided, and the four protrusions 1301 are distributed in a matrix along the circumferential direction to ensure that the force between the second transmission wheel 10 and the switching component 3 is balanced.

[0131] The slot 1302 is disposed on the inner wall of the second transmission wheel 10, and the shape and position of the slot 1302 match the protrusion 1301. The number of slots 1302 is related to the number of water outlet modes. For example, when the water outlet device has three water outlet modes, the number of slots 1302 can be 3, 6, or 9; when the water outlet device has four water outlet modes, the number of slots 1302 can be 4, 8, or 12; when the water outlet device has five water outlet modes, the number of slots 1302 can be 5, 10, or 15. In one embodiment, the water outlet device has four water outlet modes, four protrusions 1301 are provided, and eight slots 1302 are provided. The eight slots 1302 are distributed in a circumferential matrix to balance the force between the second transmission wheel 10 and the switching component 3.

[0132] During the process of the switching component 3 moving from the second position to the first position, the protrusion 1301 moves axially together with the switching component 3, and the protrusion 1301 gradually approaches the slot 1302 until the protrusion 1301 is inserted into the slot 1302, and the switching component 3 reaches the first position.

[0133] During the process of the switching component 3 moving from the first position to the second position, the protrusion 1301 moves axially together with the switching component 3. The protrusion 1301 gradually disengages from the slot 1302 until the protrusion 1301 completely leaves the slot 1302, at which point the switching component 3 reaches the second position or is about to reach the second position.

[0134] In one embodiment, the protrusion 1301 may be disposed on the inner wall of the second transmission wheel 10, and the slot 1302 may be disposed at the end of the switching component 3 away from the water distribution component 4, as long as the protrusion 1301 and the slot 1302 can be engaged and cooperated.

[0135] This application also provides a water outlet device, including a housing 100 and a water outlet mode switching mechanism as described above. The water outlet mode switching mechanism is disposed inside the housing 100 and is used to switch the water outlet mode of the water outlet device.

[0136] This water outlet device employs the aforementioned water outlet mode switching mechanism, which has a relatively simple overall structure. Switching component 3 is only connected to the transmission assembly when it is in the first position; otherwise, it is not connected. When switching component 3 is in the first position, it connects to the transmission assembly, facilitating easy switching of the water outlet mode. When switching is not required, switching component 3 disengages from the transmission assembly. In this case, the transmission assembly does not move axially synchronously with switching component 3, significantly simplifying the axial movement required. This greatly reduces the motion resistance of switching component 3 and water distribution component 4 during axial movement, and reduces the driving torque required for their axial movement. Consequently, the mechanism's response speed is significantly improved, resulting in smoother operation and higher reliability.

[0137] The water outlet device is a faucet, specifically a pull-out faucet. It offers multiple water flow modes, such as: gentle water mode, spray mode, direct spray mode, powerful rinsing mode, and misting mode. A water flow mode switching mechanism allows users to switch between different water flow modes to meet their varying needs.

[0138] The water dispensing device includes a housing 100, which is the main structure of the device and is used to install or support other mechanisms of the device. The housing 100 can be made of materials such as metal, alloy, or plastic. The housing 100 has an inlet side and an outlet side. Generally speaking, water enters the housing 100 from the inlet side and then flows out from the outlet side for user use. To provide multiple water dispensing modes, at least three water dispensing structures are provided on the outlet side of the housing 100, each corresponding to a different water dispensing mode, giving the device at least three dispensing modes. For example, the device can have three, four, or five water dispensing modes.

[0139] See Figure 1As shown, the water outlet device also includes a second water channel 14, which is located upstream of the first water channel 1. The second water channel 14 is positioned on the side of the second drive wheel 10 away from the first drive wheel 9. A third elastic member 18 is provided between the second water channel 14 and the second drive wheel 10 to support the second drive wheel 10 and prevent it from dislodging when moving away from the first drive wheel 9. Specifically, the third elastic member 18 is a spring, with one end connected to the second water channel 14 and the other end abutting against the second drive wheel 10. The end of the second water channel 14 facing away from the second drive wheel 10 is connected to a nut 19 to facilitate the installation of the water outlet device.

[0140] Of course, the water outlet device of this application also has other structures and components that are present in existing water outlet devices, which will not be elaborated here.

[0141] The following description, with reference to the accompanying drawings and taking the initial state of the water outlet device as the off state as an example, describes the opening process, closing process, and water outlet mode switching process of the water outlet device of this application:

[0142] When the water outlet device is in the off state, the switching component 3 is in the second position, see reference. Figure 4 As shown, at this time, the first elastic component 6 applies an elastic force to the switching component 3, so that the switching component 3 remains in the second position.

[0143] When the user turns on the water outlet, refer to Figure 3 As shown, water flows into the outer casing 100 through the second water channel 14, and then through the first water channel 1, acting on the side of the water distribution component 4 facing away from the water outlet network 200. When the force of the water flow is greater than the elastic force of the first elastic component 6, the water distribution component 4 and the switching component 3 move towards the water outlet network 200 until the water distribution component 4 is in contact with the water outlet panel. At this time, the channel 401 of the water distribution component 4 connects with the water outlet structure corresponding to the default water outlet mode, and the water outlet device discharges water according to the default water outlet mode.

[0144] When users need to switch water output modes, please refer to Figure 12 As shown, when the user presses button 17, the operating component 2 moves downward in the direction of the arrow (in the direction indicated by arrow x). The rack part 201 drives the first transmission wheel 9 and the second transmission wheel 10 to rotate in the first direction (in the direction indicated by arrow a). The second transmission wheel 10 drives the switching component 3 and the water distribution component 4 to rotate by a preset angle in the first direction. The channel 401 of the water distribution component 4 connects with the water outlet of the next water outlet structure, and the water outlet mode is switched to the next water outlet mode.

[0145] See Figure 13As shown, when the user releases button 17, the operating component 2 moves upward in the direction of the arrow (in the direction indicated by arrow y), and the rack part 201 drives the first transmission wheel 9 to rotate in the second direction (in the direction indicated by arrow b). The second transmission wheel 10 is limited by the pawl 15 and disengages from the first transmission wheel 9 axially. The second transmission wheel 10, the switching component 3 and the water distribution component 4 do not rotate, thereby maintaining the water output mode currently selected by the user.

[0146] When the user turns off the water outlet, refer to Figure 4 As shown, the water flow gradually decreases and the water pressure gradually decreases. When the force of the water flow is less than the elastic force of the first elastic component 6, the water distribution component 4 and the switching component 3 move away from the water outlet network group 200. During this process, when the working end of the reset component 501 abuts against the reset guide surface 502, the switching component 3 and the water distribution component 4 rotate around the axial direction until the working end of the reset component 501 inserts into the limiting groove 503. The switching component 3 and the first water channel 1 are at the upper limit in the circumferential direction, and the switching component 3 and the water distribution component 4 can no longer rotate around the axial direction. At this time, the water distribution component 4 just matches the water outlet structure corresponding to the default water outlet mode, realizing the function of restoring the default water outlet mode, and the switching component 3 returns to the second position.

[0147] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0148] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
