The automatic water-adding electric kettle usually consists of a kettle body and a base. The kettle body is placed on the base, and a water outlet column is also provided on the base. The upper end of the water outlet column is a rotatable faucet to add water to the kettle body.

In this rotary drive structure, the internal space of the faucet and the water outlet column is fully utilized, so that the setting of the rotary drive structure is very compact and reasonable, which can save setting space and is conducive to reducing the volume of the water outlet device, thereby optimizing the product design. Moreover, the structure of this mounting mechanism is relatively simple, easy to manufacture and form, and the structure is reliable, which reduces the manufacturing cost.

[0009] In an optional embodiment, a reinforcing mechanism is further included, and the reinforcing mechanism is used to strengthen the structural strength of the mounting column.

[0010] Beneficial effects: The rotary drive structure of the present invention further provides a reinforcing mechanism to reinforce the structural strength of the mounting column, so that the installation position of the driving member is more reliable, further improving the stability of the faucet rotation.

[0011] In an optional embodiment, the reinforcing mechanism includes at least two ribs, one end of the rib is connected to the outer wall of the mounting column, and the other end of the rib extends in a direction away from the mounting column.

[0012] Beneficial effects: The rotating drive structure of the present invention, the reinforcing mechanism includes at least two ribs, one end of the rib is connected to the outer wall of the mounting column, and the other end extends in the direction away from the mounting column. Such ribs can thicken the local outer wall of the mounting column, thereby improving the structural strength of the mounting column, achieving good reinforcement effect, and having a simple structure and being easy to manufacture.

[0013] In an optional embodiment, two mounting posts are provided, and the two mounting posts are symmetrically arranged relative to the output shaft of the driving member.

[0014] Beneficial effects: The rotating drive structure of the present invention has an installation mechanism including two installation columns, and the two installation columns are symmetrically arranged relative to the output axis of the driving member, so that the symmetrical sides of the driving member are fixed to the water outlet column through the installation columns, which can make the connection force between the driving member and the water outlet column more balanced, make the position of the driving member more stable, improve the reliability of the connection position of the driving member, and make the rotation of the faucet more stable and reliable.

[0015] In an optional embodiment, a limiting mechanism is further included, wherein the limiting mechanism is arranged on the water outlet column and the faucet, and the limiting mechanism is used to limit the rotation range of the faucet relative to the water outlet column.

[0016] Beneficial effect: The rotation drive structure of the present invention is also provided with a limiting mechanism on the water outlet column and the faucet. When the faucet rotates relative to the water outlet 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 adding position and the initial position, avoiding the faucet from discharging water in a non-set position and avoiding water from spilling onto the base or the table top, thereby ensuring the safe use of the water outlet device.

[0017] In an optional embodiment, the limiting mechanism includes a limiting hole and a mounting column, the limiting hole is formed on the faucet, the mounting column passes through the limiting hole and enters the faucet, the limiting hole has a first limiting edge and a second limiting edge, the first limiting edge corresponds to one of the rotation amplitude limit positions of the faucet, and the second limiting edge corresponds to another rotation amplitude limit position of the faucet.

[0018] Beneficial effects: The rotation drive structure of the present invention, the limiting mechanism includes a limiting hole and a mounting column, the limiting hole has a first limiting edge and a second limiting edge, the mounting column passes through the limiting hole and enters the faucet, during the rotation of the faucet, when the mounting column abuts the first limiting edge, the faucet rotates to a rotation amplitude limit position, such as a water adding position, so that the faucet can stop in time when it rotates to the water adding position, and when the mounting column abuts the second limiting edge, the faucet rotates to another rotation amplitude limit position, such as an initial position, so that the faucet can stop in time when it rotates to the initial position, thereby improving the accuracy of the faucet rotation amplitude and improving product reliability.

[0019] In an optional implementation, the limiting hole is an arc-shaped long hole.

[0020] Beneficial effect: In the rotation drive structure of the present invention, the limiting hole is an arc-shaped long hole, so that the structure of the limiting hole adapts to the rotation path of the mounting column, making the structure more compact and facilitating the optimization of the product structure.

[0021] In an optional embodiment, an over-torque protection member is further included, which is arranged in the faucet, one end of the over-torque protection member is connected to the output shaft of the driving member, and the other end is connected to the faucet. When the external force torque applied to the faucet is greater than a preset value, the over-torque protection member blocks the external force torque.

[0022] Beneficial effect: With the rotary drive structure of the present invention, when the user forcibly turns the faucet or hinders the rotation of the faucet, if the external force torque applied to the faucet is greater than a preset value, the over-torque protection component will block the external force torque, thereby preventing excessive external force torque from acting on the shaft of the drive component (motor), thereby forming reliable protection for the motor, making the motor less likely to be damaged, eliminating the adverse effects of improper user operation on the motor, and ensuring the service life of the motor and the water outlet device.

[0023] In an optional embodiment, the over-torque protection member includes a cover body, a first component, a second component and an elastic member, the cover body is fixed to the first component, the second component is passed through the cover body, the elastic member is placed in the cover body, one end of the elastic member abuts the cover body, and the other end abuts the second component toward the first component to make the first component and the second component mesh, 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 the present invention, the over-torque protection member includes a cover body, a first component, a second component and an elastic member. The over-torque protection member has a simple structure, is easy to set up, contains fewer parts, and has high structural reliability.

[0025] In an optional embodiment, the meshing surfaces of the first component and the second component are oblique serrated surfaces.

[0026] Beneficial effect: In the rotary drive structure of the present invention, the meshing surfaces of the first component and the second component are oblique sawtooth surfaces. During the transmission process, the first component will always provide the second component with an axial force to push the second component away, and this thrust is relative. When the axial thrust is not large (the external force torque applied to the faucet is less than or equal to the preset value), the first component will drive the second component to rotate, and when the axial thrust is large (the external force torque applied to the faucet is greater than the preset value), the axial thrust overcomes the pressure of the elastic member on the second component, and the first component and the second component will separate, thereby preventing the external force torque applied to the faucet from being transmitted to the output shaft of the drive member, thereby forming a reliable protection for the drive member.

[0027] In an optional embodiment, a connecting plate is provided at the lower portion of the faucet, the connecting plate has a mounting groove, and the cover body is disposed in the mounting groove.

[0032] Beneficial effect: The rotation drive structure of the present invention inserts the rotating shaft of the faucet connecting plate into the mounting hole of the water outlet column fixing plate, and the rotating shaft and the mounting hole are clearance-matched. On the one hand, it does not affect the rotation of the faucet relative to the water outlet column. On the other hand, the mounting hole can limit the rotating shaft and prevent the rotating shaft from deviating from the position due to external force, thereby further improving the reliability of the structure.

[0033] In the second aspect, the present invention also provides a rotation protection system, which is applied to the rotation drive structure as mentioned above, and the rotation protection system includes a control member and an in-place detection mechanism, and the in-place detection mechanism is arranged at at least one rotation amplitude limit position of the faucet, and the control member is electrically connected to the in-place detection mechanism and the driving member of the rotation drive structure.

[0034] Beneficial effect: The rotation protection system of the present invention, 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 rotation amplitude limit position through the in-place detection mechanism, so that the faucet can stop in time when it reaches the rotation amplitude limit position, thereby further improving the reliability of the structure.

[0038] Because the water outlet device of the present invention, including the rotation drive structure of the present invention, has the same beneficial effects as the rotation drive structure, it will not be described in detail here.

[0039] In an optional embodiment, the lower portion of the faucet is inserted into the water outlet column.

[0040] Beneficial effects: In the water outlet device of the present invention, the lower part of the faucet is 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.

[0072] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0073] Combine the following Figure 1-Figure 17 , describing embodiments of the rotation drive structure, rotation protection system and water outlet device of the present invention.

[0074] According to an embodiment of the present invention, a rotation driving structure is provided, which is applied to a water outlet device. The water outlet device includes a water outlet column 1 and a faucet 2. The faucet 2 is rotatably arranged on the top of the water outlet column 1 through the rotation driving structure. The rotation driving structure includes: a driving member 3 and a mounting mechanism. The driving member 3 is fixed to the water outlet column 1, and the driving member 3 drives the faucet 2 to rotate. The driving member 3 is at least partially arranged in the faucet 2; the driving member 3 is fixed to the water outlet column 1 through the mounting mechanism, and 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 driving member 3.

[0075] In this rotary drive structure, the internal space of the faucet 2 and the water outlet column 1 is fully utilized, so that the rotary drive structure is arranged very compactly and reasonably, which can save the arrangement space, and is conducive to reducing the volume of the water outlet device, thereby optimizing the product design. Moreover, the structure of this installation mechanism is relatively simple, easy to manufacture and form, and the structure is reliable, which reduces the manufacturing cost.

[0076] The rotary drive structure of this embodiment is applied to a water outlet device, such as an electric kettle, which has the functions of automatic water supply, water boiling, heat preservation, tea brewing, etc. Figure 1-Figure 2 As shown, the water outlet device includes a kettle body 11, a base 10, a water outlet column 1 and a faucet 2, etc. The kettle body 11 and the water outlet column 1 are arranged on the base 10, and the bottom of the base 10 is suitable for being placed on a platform such as a desktop. The kettle body 11 has a water storage space inside, and the faucet 2 is rotatably arranged on the top of the water outlet column 1 through a rotating driving structure, and water can be added to the kettle body 11 through the faucet 2. The faucet 2 has an initial position and a water adding position, and the faucet 2 can rotate between the initial position and the water adding position. When the faucet 2 rotates from the initial position to the water adding position, the faucet 2 can discharge water and add water to the kettle body 11. When the faucet 2 rotates from the water adding position to the initial position, the faucet 2 does not hinder the user from operating the kettle body 11.

[0077] The rotation drive structure includes: a driving member 3 and a mounting mechanism, wherein the driving member 3 is fixed to the water outlet column 1, and the driving member 3 is used to provide power for the rotation of the faucet 2 relative to the water outlet column 1, and the faucet 2 can rotate horizontally relative to the water outlet column 1 under the driving action of the driving member 3. Specifically, the driving member 3 adopts a motor, and the driving member 3 has an output shaft 301. The driving member 3 is at least partially disposed in the faucet 2, and the driving member 3 is fixed to the water outlet column 1 through the mounting mechanism.

[0078] like Figure 3-Figure 4 As shown, in this embodiment, the faucet 2 includes a faucet cover 204 and a faucet seat 205. The faucet cover 204 is placed on the top of the faucet seat 205. The faucet cover 204 and the faucet seat 205 are snap-fitted and connected to form an integral structure. In order to facilitate the installation and setting of the internal structure, the faucet cover 204 and the faucet seat 205 are detachably connected. After the faucet cover 204 and the faucet seat 205 are connected, the two enclose the installation space inside the faucet 2.

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

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

[0081] like Figure 5-Figure 7 As shown, 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 driving member 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, the water outlet column 1 is perpendicular to the base 10, and 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 driving member 3, so that the housing part of the driving member 3 is relatively fixed to the water outlet column 1.

[0083] The number of the mounting posts 5 can be set as required, such as two, three, four mounting posts 5 and the like.

[0084] Furthermore, two mounting posts 5 are provided, and the two mounting posts 5 are symmetrically arranged relative to the output shaft 301 of the driving member 3 .

[0085] In this embodiment, two mounting columns 5 are provided, and the two mounting columns 5 are symmetrically arranged relative to the output shaft 301 of the driving member 3, so that the symmetrical sides of the housing of the driving member 3 are fixed to the water outlet column 1 through the mounting columns 5, which can make the connection force between the driving member 3 and the water outlet column 1 more balanced, make the position of the driving member 3 more stable, improve the reliability of the connection position of the driving member 3, and make the rotation of the faucet 2 more stable and reliable.

[0086] In this embodiment, a threaded hole is formed at the upper end of the mounting column 5. Correspondingly, an outer wall of the shell of the driving member 3 is provided with an outwardly extending ear plate, and 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 achieving the fixation of the driving member 3 and the water outlet column 1.

[0087] Furthermore, the rotation driving structure also includes a reinforcing mechanism, which is used to strengthen 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, making the connection between the driving member 3 and the water outlet column 1 more firm and reliable, and avoiding the vibration generated during the operation of the driving member 3, which affects the connection firmness between the driving member 3 and the water outlet column 1.

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

[0090] like Figure 5-Figure 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 radially arranged outward. The connection points of the four ribs 6 and the mounting column 5 are arranged at intervals around the circumference of the mounting column 5, so that the four ribs 6 are dispersedly arranged, so as to achieve reinforcement of different positions of the outer wall of the mounting column 5, so that the structural strength of the mounting column 5 is higher.

[0091] Furthermore, the width and height of each rib 6 can be set to be the same or different according to the installation position and installation space, so as to make full use of the space and further improve the reinforcement effect of the mounting column 5. The width of the rib 6 refers to the dimension of the rib 6 extending outward from the mounting column 5, and the height of the rib 6 refers to the dimension of the rib 6 in the vertical direction.

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

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

[0094] The limiting mechanism is arranged 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, so as to prevent 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 adding position and the initial position, thereby improving the structural reliability, preventing the faucet 2 from discharging water in a non-set position, preventing water from spilling onto the base or the desktop, and ensuring the safe use of the water outlet device.

[0095] Furthermore, the limiting mechanism includes a limiting hole 7 and a mounting column 5. The limiting hole 7 is formed on the faucet 2. The mounting column 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 rotation amplitude limit positions of the faucet 2, and the second limiting edge 702 corresponds to another rotation amplitude limit position of the faucet 2.

[0096] like Figure 8 As shown, in this embodiment, a connecting plate 201 is provided in the faucet seat 205, at least part 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, and 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, and the connecting plate 201 and the inner wall of the faucet seat 205 are surrounded to form the limiting hole 7.

[0097] The limiting hole 7 is suitable for the installation column 5 to pass through. In this embodiment, two limiting holes 7 are formed so that two installation columns 5 can pass through one limiting hole 7 respectively. The faucet 2 has a water filling position (one rotation amplitude limit position) and an initial position (another rotation amplitude 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 column 5 abuts against the first limiting edge 701, the faucet 2 rotates to the water adding position, so that the faucet 2 can stop in time when it rotates to the water adding position; and when the mounting column 5 abuts against the second limiting edge 702, the faucet 2 rotates to the initial position, so that the faucet 2 can stop in time when it rotates to the initial position, thereby improving the accuracy of the faucet rotation range and improving product reliability.

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

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

[0101] In this embodiment, the limiting hole 7 is an arc-shaped long hole, so that the structural form of the limiting hole 7 adapts to the rotation path of the mounting column 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 column 5.

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

[0103] The over-torque protection member 4 is arranged in the faucet 2, one end of the over-torque protection member 4 is connected to the output shaft 301 of the driving member 3, and the other end is connected to the faucet 2. When the external force torque applied to the faucet 2 is greater than the preset value, the over-torque protection member 4 blocks the external force torque. When the faucet 2 is only driven by the driving member 3 or the faucet 2 is subjected to a small external force (for example, the improper operation of the user is not serious), the over-torque protection member 4 is a transmission member, which can transmit the driving force of the driving member 3 to the faucet 2, so as to realize the rotation of the faucet 2 relative to the water column 1. When the faucet 2 is subjected to a large external force (for example, the improper operation of the user is relatively serious), when the external force torque applied to the faucet 2 is greater than the preset value, the over-torque protection member 4 can block the external force torque, avoid the excessive external force torque from acting on the output shaft 301 of the driving member 3, and form a reliable protection for the motor. Among them, the setting and correspondence of the preset value of the external force torque can be realized through structural design, so that the preset value of the external force torque is related to the specific structure of the over-torque protection member 4.

[0104] Furthermore, the over-torque protection member 4 includes a cover body 401, a first component 402, a second component 403 and an elastic component 404. The cover body 401 is fixed to the first component 402, the second component 403 is passed through the cover body 401, and the elastic component 404 is placed in the cover body 401. One end of the elastic component 404 abuts against the cover body 401, and the other end abuts against the second component 403 toward the first component 402, so that the first component 402 and the second component 403 are meshed. 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 Figure 3-Figure 4 , Figure 13-Figure 17 As shown, the over-torque protection member 4 is a clutch structure. The over-torque protection member 4 comprises a cover body 401 , a first component 402 , a second component 403 and an elastic member 404 , and the axial direction of the over-torque protection member 4 is arranged parallel to the axial direction of the water outlet column 1 .

[0106] The cover body 401 is fixed to the first component 402, for example, by screws. After the cover body 401 is fixed to the first component 402, a cavity is formed inside the over-torque protection member 4, and a part of the structure of the second component 403 and the elastic member 404 are arranged in the cavity. The second component 403 is inserted through the cover body 401, specifically, the second component 403 is inserted through the bottom of the cover body 401, and the elastic member 404 is placed in the cover body 401, the lower end of the elastic member 404 abuts the cover body 401, and the upper end of the elastic member 404 abuts the second component 403 toward the first component 402, so that the first component 402 and the second component 403 are pressed tightly and the first component 402 and the second component 403 are kept in a meshing state. The elastic member 404 is a spring, and the elastic member 404 is in a compressed state in the cavity of the over-torque protection member 4.

[0107] The end of the first component 402 away from the second component 403 is connected to the output shaft 301, that is, the upper end of the first component 402 is connected to the output shaft 301 of the driving member 3, and the end of the second component 403 away from the first component 402 is connected to the faucet 2, that is, the lower end of the second component 403 is connected to the faucet 2. The power output by the output shaft 301 of the driving member 3 drives the first component 402 to rotate. Since the first component 402 is engaged with the second component 403, the first component 402 drives the second component 403 to rotate, and then the second component 403 drives the faucet 2 to rotate, so that the faucet 2 rotates relative to the water outlet column 1.

[0108] Specifically, the end of the first component 402 away from the second component 403 has a transmission column 406, and a transmission hole 407 is formed in the transmission column 406. The output shaft 301 is suitable for inserting into the transmission hole 407, so that the power output by the output shaft 301 drives the first component 402 to rotate. Fig.13 As shown, the transmission hole 407 is a substantially oblong hole, and a toothed edge is 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 realize over-torque protection of the motor by the over-torque protection member 4, the meshing surfaces of the first component 402 and the second component 403 are oblique sawtooth surfaces.

[0110] like Fig.16 As shown, the bottom structure of the first component 402 is shown. Fig.17The top structure of the second component 403 is shown in FIG. The first component 402 is provided with a first component meshing tooth 408 on the bottom surface facing the second component 403, and the second component 403 is provided with a second component meshing tooth 409 on the top surface facing the first component 402. The meshing surface between the first component 402 and the second component 403 is an inclined surface, that is, both sides of the first component meshing tooth 408 and the second component meshing tooth 409 are inclined surfaces, and the inclined surface is arranged at an acute angle or an obtuse angle with the axial direction of the over-torque protection member 4, as shown in FIG. Fig.15 The tooth structure in the middle is shown.

[0111] In 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 to push the second component 403 away (thrust to keep the two away). The 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, the first component 402 and the second component 403 will move away from each other.

[0112] When the axial thrust is not large (only driven by the driving force of the driving member 3, or the external force 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. When the axial thrust is large (the external force 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, the first component 402 and the second component 403 will separate, and slippage will occur between the first component 402 and the second component 403, thereby preventing the external force torque applied to the faucet 2 from being transmitted to the output shaft 301 of the driving member 3, thereby forming a reliable protection for the driving member 3.

[0113] In addition, the tooth tips of the first component meshing teeth 408 and the second component meshing teeth 409 are planes. When the first component 402 and the second component 403 are separated, the tooth tips of the first component meshing teeth 408 and the second component meshing teeth 409 may contact each other, and the first component 402 and the second component 403 may slip.

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

[0115] The bottom of the mounting groove 202 has an assembly hole 203, which is a blind hole. The end of the second component 403 away from the first component 402 has a transmission shaft 405, which is arranged at the center of the second component 403 and extends downward. The transmission shaft 405 is inserted into and fixed to the assembly hole 203 to achieve the connection between the second component 403 and the faucet 2, thereby driving the faucet 2 to rotate relative to the water outlet column 1. It can be understood that the transmission shaft 405 and the assembly hole 203 are fixed at least in the rotation direction.

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

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

[0118] In addition to limiting the rotation range of the faucet 2 relative to the water outlet column 1 by the limit mechanism of the rotation drive structure, the in-place detection mechanism can also be used to strengthen the detection and limitation of the rotation range of the faucet 2, further improving the structural reliability. The in-place detection mechanism is set at at least one rotation range limit position of the faucet 2, that is, the in-place detection mechanism is set at the initial position of the faucet 2, or the water filling position, or at the initial position and the water filling position at the same time.

[0119] In this embodiment, the in-place detection mechanism is disposed at the water filling position of the faucet 2 to simplify the structure of the water outlet device and reduce the manufacturing cost.

[0120] The in-place detection mechanism comprises a detection member 8 and a trigger member 9 , one of which is arranged on the water outlet column 1 , and the other is arranged on the faucet 2 .

[0121] In this embodiment, the detection member 8 is arranged at the upper part of the water outlet column 1, and the trigger member 9 is arranged at the lower part of the faucet 2 (that is, the lower position of the faucet seat 205). The detection member 8 adopts a photoelectric switch, and the trigger member 9 is a rib plate. When the faucet 2 is rotated into the water adding position, the rib plate is screwed into the transmitting tube and the receiving tube of the concave photoelectric switch and blocks the light between the two. The photoelectric switch sends a signal to the control member, and the faucet 2 has been rotated into place at this time.

[0122] In other embodiments, the detection member 8 may be disposed at the lower portion of the faucet 2, and the trigger member 9 may be disposed at the upper portion of the water outlet column 1. As long as the positions of the two match, trigger detection can be achieved.

[0123] The present embodiment further provides a water outlet device, comprising a water outlet column 1, a faucet 2 and the above-mentioned rotation drive structure, wherein the faucet 2 is rotatably disposed on the top of the water outlet column 1 through the rotation drive structure.

[0124] In this water outlet device, when the user operates improperly (forcefully turning the faucet 2 or hindering the faucet 2 from turning), if the external torque applied to the faucet 2 is greater than the preset value, the over-torque protection member 4 will block the external torque to prevent excessive external torque from acting on the shaft of the driving member 3 (motor), thereby forming reliable protection for the motor, making it less likely to be damaged, eliminating the adverse effects of improper user operation on the motor, and ensuring the service life of the motor and the water outlet device. In addition, a limiting mechanism is also provided on the water outlet column 1 and the faucet 2. When the faucet 2 rotates relative to the water outlet column 1, the limiting mechanism can limit the rotation range of the faucet 2, so that the faucet 2 can stop in time when it rotates to the water filling position and the initial position, thereby preventing the faucet 2 from discharging water at a non-set position and preventing water from spilling onto the base or the desktop, thereby ensuring the safe use of the water outlet device.

[0125] In this embodiment, the water outlet device is specifically an electric kettle. The water outlet device also includes a kettle body 11, which is arranged on the base 10. The top of the kettle body 11 has an opening, and the opening is detachably covered with a cover body. A faucet 12 is arranged on the top of the water outlet column 1, and the faucet 12 can be rotated so that the faucet 12 is aligned with the top opening of the kettle body 11 when it is in the water adding position to realize the water adding process. A control component is also arranged inside the base 10, and the control component is used to control the operation of the driving component 3 and the in-place detection mechanism. Of course, the water outlet device also includes other structures and components that the existing water outlet devices have, which will not be repeated here.

[0126] In this embodiment, the lower part of the faucet 2 is inserted into the water outlet column 1 to save installation space, facilitate the structural connection of the rotation drive structure, facilitate the structural layout, and optimize the product 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 is needed to be relative to the water outlet column 1, the power output by the output shaft 301 of the driving member 3 drives the first component 402 to rotate. Since the first component 402 is engaged with the second component 403, the first component 402 drives the second component 403 to rotate. The second component 403 and the faucet 2 are fixed in the rotation direction. The second component 403 drives the faucet 2 to rotate, thereby realizing the rotation of the faucet 2 relative to the water outlet column 1.

[0129] If the user forcibly turns the faucet 2 or prevents the faucet 2 from rotating while the faucet 2 is rotating 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, separating the first component 402 and the second component 403, thereby blocking excessive external torque from being transmitted to the motor output shaft.

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

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

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