Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a rotation drive structure, a rotation protection system, and a water outlet device. Background Technology

[0002] An automatic water-filling electric kettle is a smart appliance that integrates functions such as automatic water filling, boiling, heat preservation, and tea brewing. It is suitable for various occasions such as homes and offices. An automatic water-filling electric kettle usually consists of two parts: the kettle body and the base. The kettle body is placed on the base, and the base is equipped with a water jet. The top of the water jet is a rotatable faucet for adding water to the kettle body.

[0003] The faucet of existing electric kettles is driven by a motor, but the faucet's rotation drive structure is relatively loose, resulting in a loose internal structure of the faucet and water jet, making the product larger and the user experience poor. Utility Model Content

[0004] In view of this, the present invention provides a rotation drive structure, a rotation protection system and a water outlet device to solve the problem that the existing electric kettle faucet rotation drive structure is loose and not compact, resulting in a large product size.

[0005] In a first aspect, this utility model provides a rotation drive structure applied to a water outlet device, the water outlet device including a water column and a faucet, the faucet being rotatably mounted on top of the water column via the rotation drive structure, the rotation drive structure comprising:

[0006] A driving component is fixed to the water column, and the driving component drives the faucet to rotate. The driving component is at least partially disposed inside the faucet.

[0007] The installation mechanism is used to fix the driving component to the water outlet column. The installation mechanism includes at least two installation columns, one end of which is connected to the water outlet column and the other end of which enters the faucet and is connected to the driving component.

[0008] Beneficial Effects: The rotary drive structure of this utility model includes a drive component and a mounting mechanism. The drive component is at least partially disposed inside the faucet. The drive component is fixed to the water column via the mounting mechanism, which includes at least two mounting columns. One end of each mounting column is connected to the water column, and the other end enters the faucet and connects to the drive component. This allows most of the drive component's structure to be housed inside the faucet, while simultaneously enabling the drive component to rotate the faucet. This rotary drive structure fully utilizes the internal space of the faucet and water column, resulting in a very compact and rational design that saves space and reduces the size of the water outlet device, thereby optimizing product design. Furthermore, this mounting mechanism has a simple structure, is easy to manufacture, and is reliable, reducing manufacturing costs.

[0009] In an alternative embodiment, a reinforcing mechanism is also included to enhance the structural strength of the mounting column.

[0010] Beneficial effects: The rotation drive structure of this utility model also provides a reinforcing mechanism to strengthen the structural strength of the mounting column, so as to make the installation position of the drive component more reliable and further improve the stability of the faucet rotation.

[0011] In one alternative embodiment, the reinforcing mechanism includes at least two ribs, one end of which is connected to the outer wall of the mounting post, and the other end of which extends away from the mounting post.

[0012] Beneficial effects: The rotation drive structure of this utility model has a reinforcing mechanism including at least two ribs. One end of the rib is connected to the outer wall of the mounting column, and the other end extends away from the mounting column. This rib can thicken the local outer wall of the mounting column, thereby improving the structural strength of the mounting column, resulting in a good reinforcement effect. Moreover, the structure is simple and easy to manufacture.

[0013] In one alternative embodiment, two mounting posts are provided, and the two mounting posts are symmetrically arranged relative to the output axis of the drive member.

[0014] Beneficial effects: The rotation drive structure of this utility model includes two mounting columns in the mounting mechanism. The two mounting columns are symmetrically arranged relative to the output axis of the drive component, so that the symmetrical sides of the drive component are fixed to the water outlet column through the mounting columns. This makes the connection force between the drive component and the water outlet column more balanced, the position of the drive component more stable, and improves the reliability of the connection position of the drive component, making the rotation of the faucet more stable and reliable.

[0015] In one optional embodiment, a limiting mechanism is further included, which is disposed on the water column and the faucet, and the limiting mechanism is used to limit the rotation range of the faucet relative to the water column.

[0016] Beneficial effects: The rotation drive structure of this utility model is equipped with a limiting mechanism on the water column and the faucet. When the faucet rotates relative to the water column, the limiting mechanism can limit the rotation range of the faucet, so that the faucet can stop in time when it rotates to the water filling position and the initial position, avoiding water from being discharged from the faucet in a non-set position, preventing water from being spilled on the base or table, and ensuring the safe use of the water dispensing device.

[0017] In one optional embodiment, the limiting mechanism includes a limiting hole and a mounting post. The limiting hole is formed in the faucet, and the mounting post passes through the limiting hole into the faucet. The limiting hole has a first limiting edge and a second limiting edge. The first limiting edge corresponds to one of the extreme rotation range positions of the faucet, and the second limiting edge corresponds to the other extreme rotation range position of the faucet.

[0018] Beneficial effects: The rotation drive structure of this utility model includes a limiting mechanism comprising a limiting hole and a mounting post. The limiting hole has a first limiting edge and a second limiting edge. The mounting post passes through the limiting hole and enters the faucet. During the rotation of the faucet, when the mounting post abuts against the first limiting edge, the faucet rotates to a limit position of rotation amplitude, such as the water filling position, allowing the faucet to stop in time when it reaches the water filling position. When the mounting post abuts against the second limiting edge, the faucet rotates to another limit position of rotation amplitude, such as the initial position, allowing the faucet to stop in time when it reaches the initial position. This improves the accuracy of the faucet's rotation amplitude and enhances product reliability.

[0019] In one optional embodiment, the limiting hole is an arc-shaped elongated hole.

[0020] Beneficial effects: The rotation drive structure of this utility model has an arc-shaped elongated hole for limiting the hole, so that the structure of the limiting hole can be adapted to the rotation path of the mounting column, making the structure more compact and conducive to the optimization of the product structure.

[0021] In one optional embodiment, an over-torque protection component is further included. The over-torque protection component is disposed inside the faucet. One end of the over-torque protection component is connected to the output shaft of the drive component, and the other end is connected to the faucet. When the external torque applied to the faucet is greater than a preset value, the over-torque protection component blocks the external torque.

[0022] Beneficial effects: When the user forcibly turns the faucet or obstructs the faucet from turning, if the external torque applied to the faucet exceeds the preset value, the over-torque protection component will block the external torque, preventing excessive external torque from acting on the shaft of the drive component (motor), thus providing reliable protection for the motor, making the motor less prone to damage, eliminating the adverse effects of improper user operation on the motor, and ensuring the service life of the motor and water outlet device.

[0023] In one optional embodiment, the over-torsion protection component includes a cover, a first component, a second component, and an elastic element. The cover is fixed to the first component, the second component passes through the cover, and the elastic element is placed inside the cover. One end of the elastic element abuts against the cover, and the other end abuts against the second component towards the first component, thereby engaging the first component and the second component. The end of the first component away from the second component is connected to the output shaft, and the end of the second component away from the first component is connected to the faucet.

[0024] Beneficial effects: The rotation drive structure of this utility model includes an over-torsion protection component comprising a cover, a first component, a second component, and an elastic component. This over-torsion protection component has a simple structure, is easy to install, contains few parts, and has high structural reliability.

[0025] In one alternative embodiment, the meshing surfaces of the first component and the second component are oblique sawtooth surfaces.

[0026] Beneficial effects: In the rotation drive structure of this utility model, the meshing surface of the first and second components is a serrated surface. During transmission, the first component always provides the second component with an axial force that pushes it away. This thrust is relative. When the axial thrust is small (the external torque applied to the faucet is less than or equal to a preset value), the first component will drive the second component to rotate. When the axial thrust is large (the external torque applied to the faucet is greater than the preset value), the axial thrust overcomes the pressure of the elastic element on the second component, and the first and second components will separate. This prevents the external torque applied to the faucet from being transmitted to the output shaft of the drive component, thus providing reliable protection for the drive component.

[0027] In one optional embodiment, the lower part of the faucet is provided with a connecting plate, the connecting plate having a mounting groove, and the cover is disposed in the mounting groove.

[0028] Beneficial effects: The rotating drive structure of this utility model has a connecting plate at the bottom of the faucet, and the cover is set in the mounting groove of the connecting plate, so as to make the over-torsion protection component more stable and the structure more compact.

[0029] In one alternative embodiment, the bottom of the mounting groove has a mounting hole, and the end of the second component away from the first component has a drive shaft, which is inserted into and fixed to the mounting hole.

[0030] Beneficial effects: The rotation drive structure of this utility model has a simple structure and good reliability. The transmission shaft of the second component is inserted into the assembly hole at the bottom of the mounting groove to realize the transmission.

[0031] In one optional embodiment, a rotating shaft is provided on the side of the connecting plate facing the water outlet column, a fixing plate is provided inside the water outlet column, the fixing plate is formed with mounting holes, the rotating shaft is inserted into the mounting holes, and the rotating shaft and the mounting holes are clearance-fitted.

[0032] Beneficial effects: The rotation drive structure of this utility model, by inserting the rotating shaft of the faucet connecting plate into the mounting hole of the water column fixing plate, and with the rotating shaft and the mounting hole in clearance fit, not only does not affect the rotation of the faucet relative to the water column, but also the mounting hole can limit the rotating shaft and prevent the rotating shaft from deviating from its position due to external forces, thereby further improving the reliability of the structure.

[0033] Secondly, this utility model also provides a rotation protection system applied to the rotation drive structure as described above. The rotation protection system includes a control component and a position detection mechanism. The position detection mechanism is disposed at at least one extreme position of the rotation amplitude of the faucet. The control component is electrically connected to the position detection mechanism and the drive component of the rotation drive structure.

[0034] Beneficial effects: The rotation protection system of this utility model, when applied to the rotation drive structure as described above, not only has the same beneficial effects as the rotation drive structure, but also can detect whether the faucet has reached the limit position of rotation amplitude through the position detection mechanism, so that the faucet can stop in time when it reaches the limit position of rotation amplitude, further improving the reliability of the structure.

[0035] In one optional embodiment, the positioning detection mechanism includes a detection element and a trigger element, one of which is disposed on the water column and the other is disposed on the faucet.

[0036] Beneficial effects: The rotation protection system of this utility model has a relatively simple positioning detection mechanism that is easy to set up and install, which helps to reduce product costs.

[0037] Thirdly, this utility model also provides a water outlet device, including a water outlet column, a faucet, and a rotation drive structure as described above, wherein the faucet is rotatably disposed on the top of the water outlet column via the rotation drive structure.

[0038] Since the water outlet device of this utility model, including the rotation drive structure of this utility model, has the same beneficial effects as the rotation drive structure, it will not be described in detail here.

[0039] In one alternative embodiment, the lower part of the faucet is inserted into the water jet.

[0040] Beneficial effects: The water outlet device of this utility model has the lower part of the faucet inserted into the water outlet column, which saves installation space, facilitates structural connection, makes the structure of the water outlet device more compact, and optimizes the product appearance of the water outlet device.

[0041] In one alternative implementation, the water dispensing device is an electric kettle. Attached Figure Description

[0072] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0073] The following is combined with Figures 1-17 This document describes embodiments of the rotation drive structure, rotation protection system, and water outlet device of this utility model.

[0074] According to an embodiment of the present invention, a rotation drive structure is provided for use in a water outlet device. The water outlet device includes a water outlet column 1 and a faucet 2. The faucet 2 is rotatably mounted on the top of the water outlet column 1 via the rotation drive structure. The rotation drive structure includes a drive component 3 and a mounting mechanism. The drive component 3 is fixed to the water outlet column 1 and drives the faucet 2 to rotate. The drive component 3 is at least partially disposed inside the faucet 2. The drive component 3 is fixed to the water outlet column 1 via the mounting mechanism. The mounting mechanism includes at least two mounting columns 5. One end of the mounting column 5 is connected to the water outlet column 1, and the other end enters the faucet 2 and is connected to the drive component 3.

[0075] This rotary drive structure makes full use of the internal space of the faucet 2 and the water column 1, resulting in a very compact and reasonable arrangement of the rotary drive structure. This saves installation space, reduces the size of the water outlet device, and optimizes product design. Moreover, this installation mechanism has a relatively simple structure, is easy to manufacture, and is reliable, thus reducing manufacturing costs.

[0076] The rotation drive structure in this embodiment is applied to a water dispensing device, such as an electric kettle, which has functions such as automatic water filling, boiling, heat preservation, and tea brewing. Figures 1-2 As shown, the water dispensing device includes a kettle body 11, a base 10, a water column 1, and a faucet 2. The kettle body 11 and the water column 1 are mounted on the base 10, and the bottom of the base 10 is suitable for placement on a table or other platform. The kettle body 11 has a water storage space inside. The faucet 2 is rotatably mounted on top of the water column 1 via a rotation drive structure, allowing water to be added to the kettle body 11. The faucet 2 has an initial position and a water-filling position, and can rotate between the initial position and the water-filling position. When the faucet 2 rotates from the initial position to the water-filling position, water can be dispensed from the faucet 2 to add water to the kettle body 11. When the faucet 2 rotates from the water-filling position back to the initial position, the faucet 2 does not obstruct the user's operation of the kettle body 11.

[0077] The rotation drive structure includes a drive component 3 and a mounting mechanism. The drive component 3 is fixed to the water outlet column 1 and provides power for the rotation of the faucet 2 relative to the water outlet column 1. Under the driving action of the drive component 3, the faucet 2 can rotate horizontally relative to the water outlet column 1. Specifically, the drive component 3 is a motor and has an output shaft 301. The drive component 3 is at least partially disposed inside the faucet 2 and is fixed to the water outlet column 1 by the mounting mechanism.

[0078] like Figures 3-4 As shown, in this embodiment, the faucet 2 includes a faucet cover 204 and a faucet base 205. The faucet cover 204 is placed on top of the faucet base 205, and the faucet cover 204 and the faucet base 205 are fastened together to form an integral structure. To facilitate the installation of the internal structure, the faucet cover 204 and the faucet base 205 are detachably connected. After the faucet cover 204 and the faucet base 205 are connected, they together form the internal installation space of the faucet 2.

[0079] The driving component 3 is at least partially disposed within the installation space of the faucet 2, so as to make the internal structure of the water column 1 and the faucet 2 more compact and the structural layout more reasonable. The driving component 3 is fixed to the water column 1 through the installation mechanism, so that the driving component 3 drives the faucet 2 to rotate relative to the water column 1.

[0080] The installation mechanism includes at least two mounting columns 5, one end of which is connected to the water outlet column 1, and the other end enters the faucet 2 and is connected to the drive component 3.

[0081] like Figures 5-7 As shown, the installation mechanism includes at least two mounting columns 5. One end of each mounting column 5 is connected to the water outlet column 1, and the other end enters the faucet 2 and is connected to the drive component 3. Optionally, the mounting column 5 and the water outlet column 1 are integrally formed.

[0082] In this embodiment, the mounting column 5 is arranged parallel to the axial direction of the water outlet column 1, and the water outlet column 1 is perpendicular to the base 10. The axial direction of the water outlet column 1 is the vertical direction. Specifically, the lower end of the mounting column 5 is connected to the water outlet column 1, and the upper end of the mounting column 5 enters the faucet 2 and is connected to the drive component 3, so that the housing part of the drive component 3 is relatively fixed to the water outlet column 1.

[0083] The number of mounting columns 5 can be set as needed, such as two, three, or four mounting columns 5.

[0084] Furthermore, there are two mounting posts 5, which are symmetrically arranged relative to the output shaft 301 of the drive component 3.

[0085] In this embodiment, there are two mounting posts 5, and the two mounting posts 5 are symmetrically arranged relative to the output shaft 301 of the drive component 3. This allows the symmetrical sides of the drive component 3 housing to be fixed to the water outlet column 1 through the mounting posts 5, which makes the connection force between the drive component 3 and the water outlet column 1 more balanced, the position of the drive component 3 more stable, and improves the reliability of the connection position of the drive component 3, making the rotation of the faucet 2 more stable and reliable.

[0086] In this embodiment, the upper end of the mounting column 5 is formed with a threaded hole. Correspondingly, the outer wall of the housing of the drive component 3 is provided with an outwardly protruding ear plate. The ear plate is formed with a through hole. Fasteners (such as screws) can pass through the through hole and be assembled with the threaded hole of the mounting column 5, thereby realizing the fixation of the drive component 3 and the water outlet column 1.

[0087] Furthermore, the rotation drive structure also includes a reinforcing mechanism to enhance the structural strength of the mounting column 5.

[0088] The reinforcing mechanism is used to strengthen the structural strength of the mounting column 5, making the structural strength of the mounting column 5 higher, and making the connection between the drive component 3 and the water outlet column 1 more secure and reliable, so as to avoid the vibration generated during the operation of the drive component 3 from affecting the connection between the drive component 3 and the water outlet column 1.

[0089] Furthermore, the reinforcing mechanism includes at least two ribs 6, one end of which is connected to the outer wall of the mounting column 5, and the other end extends away from the mounting column 5.

[0090] like Figures 5-6 As shown, the reinforcing mechanism includes at least two ribs 6. In this embodiment, four ribs 6 are provided. One end of each rib 6 is connected to the outer wall of the mounting column 5, and the other end extends in a direction away from the mounting column 5, that is, the other end of the rib 6 is arranged radially outward. The connection points of the four ribs 6 to the mounting column 5 are arranged at intervals around the circumference of the mounting column 5, so that the four ribs 6 are distributed to reinforce different positions of the outer wall of the mounting column 5, thereby increasing the structural strength of the mounting column 5.

[0091] Furthermore, depending on the installation location and available space, the width and height of each reinforcing bar 6 can be set to be the same or different, thus making full use of the space and further improving the reinforcement effect on the installation column 5. The width of the reinforcing bar 6 refers to the dimension of the reinforcing bar 6 extending outward from the installation column 5, while the height of the reinforcing bar 6 refers to the dimension of the reinforcing bar 6 in the vertical direction.

[0092] In other embodiments, the number of reinforcing bars 6 may be two, three, five, etc.

[0093] Furthermore, the rotation drive structure also includes a limiting mechanism, which is disposed on the water outlet column 1 and the faucet 2. The limiting mechanism is used to limit the rotation amplitude of the faucet 2 relative to the water outlet column 1.

[0094] The limiting mechanism is set on the water outlet column 1 and the faucet 2. The limiting mechanism is used to limit the rotation range of the faucet 2 relative to the water outlet column 1, thereby preventing the faucet 2 from rotating too much relative to the water outlet column 1, so that the faucet 2 can stop in time when it rotates to the water filling position and the initial position, improving the structural reliability, preventing the faucet 2 from dispensing water in non-set positions, preventing water from splashing onto the base or table, and ensuring the safe use of the water dispensing device.

[0095] Furthermore, the limiting mechanism includes a limiting hole 7 and a mounting post 5. The limiting hole 7 is formed in the faucet 2, and the mounting post 5 passes through the limiting hole 7 and enters the faucet 2. The limiting hole 7 has a first limiting edge 701 and a second limiting edge 702. The first limiting edge 701 corresponds to one of the extreme rotation range positions of the faucet 2, and the second limiting edge 702 corresponds to the other extreme rotation range position of the faucet 2.

[0096] like Figure 8 As shown, in this embodiment, a connecting plate 201 is provided inside the faucet seat 205. At least a portion of the outer edge of the connecting plate 201 is connected to the inner wall of the faucet seat 205, and the connecting plate 201 can be integrally formed with the faucet seat 205. The connecting plate 201 is formed with a limiting hole 7. In this embodiment, part of the structure of the connecting plate 201 is hollowed out, so that part of the outer edge of the connecting plate 201 is missing. The connecting plate 201 and the inner wall of the faucet seat 205 together form the limiting hole 7.

[0097] The limiting hole 7 is suitable for the mounting post 5 to pass through. In this embodiment, two limiting holes 7 are formed so that the two mounting posts 5 pass through one limiting hole 7 respectively. The faucet 2 has a water filling position (one rotation range limit position) and an initial position (another rotation range limit position). Correspondingly, the limiting hole 7 has a first limiting edge 701 and a second limiting edge 702. In this embodiment, the first limiting edge 701 corresponds to the water filling position of the faucet 2, and the second limiting edge 702 corresponds to the initial position of the faucet 2.

[0098] During the rotation of the faucet 2, when the mounting post 5 abuts against the first limit edge 701, the faucet 2 rotates to the water filling position, allowing the faucet 2 to stop in time when it reaches the water filling position. When the mounting post 5 abuts against the second limit edge 702, the faucet 2 rotates to the initial position, allowing the faucet 2 to stop in time when it reaches the initial position, thus improving the accuracy of the faucet rotation amplitude and enhancing product reliability.

[0099] In addition, since the outer wall of the mounting column 5 is provided with ribs 6, when the mounting column 5 abuts against the first limiting edge 701, the ribs 6 abut against the first limiting edge 701, that is, the mounting column 5 abuts against the first limiting edge 701 through the ribs 6; when the mounting column 5 abuts against the second limiting edge 702, the ribs abut against the second limiting edge 702, that is, the mounting column 5 abuts against the second limiting edge 702 through the ribs 6.

[0100] Furthermore, the limiting hole 7 is an arc-shaped elongated hole.

[0101] In this embodiment, the limiting hole 7 is an arc-shaped elongated hole, so that the structural shape of the limiting hole 7 adapts to the rotation path of the mounting post 5, making the structure more compact and facilitating the optimization of the product structure. Specifically, the curvature of the limiting hole 7 matches the rotation curvature of the mounting post 5.

[0102] Furthermore, the rotation drive structure also includes an over-torque protection component 4, which is installed inside the faucet 2. One end of the over-torque protection component 4 is connected to the output shaft 301 of the drive component 3, and the other end is connected to the faucet 2. When the external torque applied to the faucet 2 is greater than a preset value, the over-torque protection component 4 blocks the external torque.

[0103] An over-torque protection element 4 is installed inside the faucet 2. One end of the over-torque protection element 4 is connected to the output shaft 301 of the drive element 3, and the other end is connected to the faucet 2. When the external torque applied to the faucet 2 exceeds a preset value, the over-torque protection element 4 blocks the external torque. When the faucet 2 is only driven by the drive element 3 or when the faucet 2 is subjected to a small external force (e.g., minor improper operation by the user), the over-torque protection element 4 acts as a transmission component, transmitting the driving force of the drive element 3 to the faucet 2, enabling the faucet 2 to rotate relative to the water column 1. However, when the faucet 2 is subjected to a large external force (e.g., severe improper operation by the user), and the external torque applied to the faucet 2 exceeds the preset value, the over-torque protection element 4 blocks the external torque, preventing excessive external torque from acting on the output shaft 301 of the drive element 3, thus providing reliable protection for the motor. The preset value of the external torque can be set and matched through structural design, making the preset value of the external torque related to the specific structure of the over-torque protection element 4.

[0104] Furthermore, the over-torsion protection component 4 includes a cover 401, a first component 402, a second component 403, and an elastic component 404. The cover 401 is fixed to the first component 402, the second component 403 is inserted through the cover 401, and the elastic component 404 is placed inside the cover 401. One end of the elastic component 404 abuts against the cover 401, and the other end abuts against the second component 403 towards the first component 402, so that the first component 402 and the second component 403 are engaged. The end of the first component 402 away from the second component 403 is connected to the output shaft 301, and the end of the second component 403 away from the first component 402 is connected to the faucet 2.

[0105] like Figures 3-4 , Figures 13-17 As shown, the over-torque protection component 4 is a clutch structure. The over-torque protection component 4 includes a cover 401, a first component 402, a second component 403, and an elastic component 404. The axial direction of the over-torque protection component 4 is parallel to the axial direction of the water column 1.

[0106] The cover 401 is fixed to the first component 402, for example, by screws. After the cover 401 is fixed to the first component 402, a cavity is formed inside the over-torsion protection member 4, and part of the structure of the second component 403 and the elastic member 404 are disposed in this cavity. The second component 403 passes through the cover 401, specifically, the second component 403 passes through the bottom of the cover 401, and the elastic member 404 is placed inside the cover 401. The lower end of the elastic member 404 abuts against the cover 401, and the upper end of the elastic member 404 abuts against the second component 403 towards the first component 402, so that the first component 402 and the second component 403 are pressed together and kept in an engaged state. The elastic member 404 is a spring, and the elastic member 404 is in a compressed state inside the cavity of the over-torsion protection member 4.

[0107] The end of the first component 402 furthest from the second component 403 is connected to the output shaft 301, meaning the upper end of the first component 402 is connected to the output shaft 301 of the drive component 3. The end of the second component 403 furthest from the first component 402 is connected to the faucet 2, meaning the lower end of the second component 403 is connected to the faucet 2. The power output from the output shaft 301 of the drive component 3 drives the first component 402 to rotate. Since the first component 402 and the second component 403 are engaged, the first component 402 drives the second component 403 to rotate, which in turn drives the faucet 2 to rotate, thus achieving the rotation of the faucet 2 relative to the water column 1.

[0108] Specifically, the end of the first component 402 furthest from the second component 403 has a transmission post 406, and a transmission hole 407 is formed inside the transmission post 406. The output shaft 301 is adapted to be inserted into the transmission hole 407 so that the power output by the output shaft 301 drives the first component 402 to rotate. Figure 13 As shown, the transmission hole 407 is an oblong hole, and toothed edges are formed on the inner wall of the transmission hole 407. The cross-sectional shape of the output shaft 301 perpendicular to the axial direction matches the shape of the transmission hole 407 to improve the transmission reliability between the output shaft 301 and the first component 402.

[0109] In order to achieve over-torque protection for the motor by the over-torque protection component 4, the meshing surface of the first component 402 and the second component 403 is a serrated surface.

[0110] like Figure 16 As shown, this is the bottom structure of the first component 402, as follows: Figure 17The diagram shows the top structure of the second component 403. The bottom surface of the first component 402 facing the second component 403 has a first component meshing tooth 408, and the top surface of the second component 403 facing the first component 402 has a second component meshing tooth 409. The meshing surface between the first component 402 and the second component 403 is an inclined plane; that is, both sides of the first component meshing tooth 408 and the second component meshing tooth 409 are inclined planes. These inclined planes form an acute or obtuse angle with the axial direction of the over-torsion protection component 4. Figure 15 The tooth-like structure in the middle is shown.

[0111] During the process of the first component 402 driving the second component 403 to rotate, the first component 402 will always provide the second component 403 with an axial force that pushes the second component 403 away (a thrust that makes the two move away from each other). This thrust is relative, that is, the first component 402 pushes the second component 403 away, and the second component 403 also pushes the first component 402 away. If the thrust is too large, it will cause the first component 402 and the second component 403 to move away from each other.

[0112] When the axial thrust is small (only driven by the driving force of the drive member 3, or the external torque applied to the faucet 2 is less than or equal to the preset value), the meshing surfaces of the first component meshing teeth 408 and the second component meshing teeth 409 are in contact, and the first component 402 will drive the second component 403 to rotate. However, when the axial thrust is large (the external torque applied to the faucet 2 is greater than the preset value), the axial thrust overcomes the pressure of the elastic member 404 on the second component 403, and the first component 402 and the second component 403 will separate. Slippage will occur between the first component 402 and the second component 403, thereby preventing the external torque applied to the faucet 2 from being transmitted to the output shaft 301 of the drive member 3, thus providing reliable protection for the drive member 3.

[0113] Furthermore, the tips of the first component meshing teeth 408 and the second component meshing teeth 409 are flat. When the first component 402 and the second component 403 are separated, the tips of the first component meshing teeth 408 and the second component meshing teeth 409 can contact each other, and the first component 402 and the second component 403 can slip.

[0114] like Figure 4 As shown, in this embodiment, the connecting plate 201 has a mounting groove 202, which is located at the center of the connecting plate 201. The mounting groove 202 is recessed downwards, and the internal dimensions of the mounting groove 202 match the external dimensions of the cover 401. The cover 401 is located in the mounting groove 202 to make the position of the over-torsion protection member 4 more stable.

[0115] The bottom of the mounting groove 202 has a mounting hole 203, which is a blind hole. The end of the second component 403 furthest from the first component 402 has a drive shaft 405. The drive shaft 405 is located at the center of the second component 403 and extends downwards. The drive shaft 405 is inserted into and fixed to the mounting hole 203 to connect the second component 403 to the faucet 2, thereby causing the faucet 2 to rotate relative to the water jet 1. It is understood that the drive shaft 405 and the mounting hole 203 are fixed at least in the direction of rotation.

[0116] A rotating shaft 206 is provided on the side of the connecting plate 201 facing the water outlet column 1. A fixing plate 101 is provided inside the water outlet column 1, and the fixing plate 101 is formed with mounting holes. The rotating shaft 206 is inserted into the mounting holes, and the rotating shaft 206 is clearance-fitted with the mounting holes. By inserting the rotating shaft 206 of the connecting plate 201 into the mounting holes of the fixing plate 101, with the rotating shaft 206 clearance-fitted with the mounting holes, on the one hand, the rotation of the faucet 2 relative to the water outlet column 1 is not affected; on the other hand, the mounting holes can limit the rotation of the rotating shaft 206 and prevent the rotating shaft 206 from deviating from its position due to external forces, further improving the reliability of the structure. In this embodiment, the mounting holes are through holes to facilitate structural connection.

[0117] This embodiment also provides a rotation protection system applied to the above-mentioned rotation drive structure. The rotation protection system includes a control component and a position detection mechanism. The position detection mechanism is set at at least one rotation amplitude limit position of the faucet 2. The control component is electrically connected to the position detection mechanism and the drive component 3 of the rotation drive structure.

[0118] In addition to limiting the rotation amplitude of the faucet 2 relative to the water column 1 through the limiting mechanism of the rotation drive structure, a position detection mechanism can be used to enhance the detection and limitation of the rotation amplitude of the faucet 2, further improving the structural reliability. The position detection mechanism is set at at least one extreme position of the rotation amplitude of the faucet 2, that is, the position detection mechanism is set at the initial position of the faucet 2, or the water filling position, or both the initial position and the water filling position.

[0119] In this embodiment, the positioning detection mechanism is located at the water filling position of the faucet 2 to simplify the structure of the water outlet device and reduce manufacturing costs.

[0120] The detection mechanism includes a detection element 8 and a trigger element 9. One of the detection element 8 and the trigger element 9 is located in the water column 1, and the other is located in the faucet 2.

[0121] In this embodiment, the detection element 8 is located at the upper part of the water column 1, and the trigger element 9 is located at the lower part of the faucet 2 (i.e., the lower part of the faucet seat 205). The detection element 8 is a photoelectric switch, and the trigger element 9 is a rib. When the faucet 2 is rotated to the water filling position, the rib is screwed into the space between the transmitting tube and the receiving tube of the concave photoelectric switch and blocks the light between them. The photoelectric switch sends a signal to the control element, indicating that the faucet 2 has been rotated to the correct position.

[0122] In other embodiments, the detection element 8 can be located at the lower part of the faucet 2, and the trigger element 9 can be located at the upper part of the water column 1. As long as the two are positioned correctly, trigger detection can be achieved.

[0123] This embodiment also provides a water outlet device, including a water outlet column 1, a faucet 2, and a rotation drive structure as described above. The faucet 2 is rotatably mounted on the top of the water outlet column 1 via the rotation drive structure.

[0124] In this water dispensing device, if the user operates it improperly (forcibly turning the faucet 2 or obstructing its rotation), and the applied external torque to the faucet 2 exceeds a preset value, the over-torque protection component 4 will block the external torque, preventing excessive external torque from acting on the shaft of the drive component 3 (motor). This provides reliable protection for the motor, making it less prone to damage and eliminating the adverse effects of improper user operation on the motor, thus ensuring the service life of the motor and the water dispensing device. Furthermore, limit mechanisms are installed on the water column 1 and the faucet 2. When the faucet 2 rotates relative to the water column 1, the limit mechanism can limit the rotation amplitude of the faucet 2, ensuring that the faucet 2 stops in time when it reaches the water filling position or the initial position. This prevents the faucet 2 from dispensing water from outside the set position, avoids water spilling onto the base or table, and ensures the safe use of the water dispensing device.

[0125] In this embodiment, the water dispensing device is specifically an electric kettle. The water dispensing device also includes a kettle body 11, which is mounted on a base 10. The top of the kettle body 11 has an opening, which is detachably covered by a lid. A faucet 12 is mounted on the top of the water column 1. The faucet 12 can rotate so that when in the water-filling position, it is aligned with the top opening of the kettle body 11 to complete the water filling process. Control components are also provided inside the base 10 to control the operation of the drive component 3 and the positioning detection mechanism. Of course, this water dispensing device also includes other structures and components common to existing water dispensing devices, which will not be elaborated here.

[0126] In this embodiment, the lower part of the faucet 2 is inserted into the water column 1 to save space, facilitate the structural connection of the rotation drive structure, simplify the structural layout, and optimize the appearance of the water outlet device.

[0127] The working process of the rotary drive structure in the water outlet device of this embodiment is described below:

[0128] When the faucet 2 needs to be positioned relative to the water column 1, the power output from the output shaft 301 of the drive component 3 drives the first component 402 to rotate. Since the first component 402 meshes with the second component 403, the first component 402 drives the second component 403 to rotate. The second component 403 is fixed to the faucet 2 in the direction of rotation. The second component 403 drives the faucet 2 to rotate, thereby realizing the rotation of the faucet 2 relative to the water column 1.

[0129] If the user forcibly rotates the faucet 2 or obstructs the rotation of the faucet 2 during the rotation of the faucet 2 relative to the water column 1, the thrust of the meshing teeth between the first component 402 and the second component 403 will cause the first component 402 and the second component 403 to move away from each other, thereby separating the first component 402 and the second component 403 and blocking the transmission of excessive external torque to the motor output shaft.

[0130] During the rotation of the faucet 2 relative to the water column 1, when the mounting column 5 abuts against the first limit edge 701, the faucet 2 rotates to the water outlet position, and at the same time, the trigger element 9 of the position detection mechanism triggers the detection element 8; when the mounting column 5 abuts against the second limit edge 702, the faucet 2 rotates to the initial position.

[0131] It should be noted that by controlling the rotation parameters of the drive component 3 through the control component, the rotation position of the faucet 2 can also be controlled, further improving the accuracy of the control of the rotation amplitude of the faucet 2.

[0132] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
