When the axial pushing force is not large (the torque of the external force applied to the rotating member is less than or equal to a preset value), the first component 402 drives the second component 403 to rotate, and when the axial pushing force is large (the torque of the external force applied to the rotating member is greater than the preset value), the axial pushing force overcomes the pressure of the elastic member on the second component 403, the first component 402 and the second component 403 are separated, thereby avoiding the transmission of the torque of the external force applied to the rotating member to the output shaft of the driving member, and thus reliably protecting the driving member.

[0087] The embodiment also provides a rotating protection structure applied to a water outlet device, the water outlet device comprising a water outlet column 1 and a faucet 2, the faucet 2 being rotatably arranged at the top of the water outlet column 1 through the rotating protection structure, and the rotating protection structure comprising a driving member 3 and an over-torque protection member 4, the driving member 3 being fixed to the water outlet column 1 and driving the faucet 2 to rotate, and the over-torque protection member 4 being arranged in the faucet 2, one end of the over-torque protection member 4 being connected to an output shaft 301 of the driving member 3, and the other end of the over-torque protection member 4 being connected to the faucet 2, the over-torque protection member 4 blocking the torque of an external force applied to the faucet 2 when the torque of the external force applied to the faucet 2 is greater than a preset value.

[0088] The rotating protection structure can block the torque of the external force applied to the faucet 2 when the user forcibly rotates the faucet 2 or hinders the rotation of the faucet 2, and the torque of the external force is greater than the preset value, thereby avoiding the excessive torque of the external force acting on the shaft of the driving member 3 (motor), reliably protecting the motor, preventing the motor from being easily damaged, eliminating the adverse effects of improper operation of the user on the motor, and ensuring the service life of the motor and the water outlet device.

When the faucet 2 is only driven by the driving force of 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 component, 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 outlet column 1. When the faucet 2 is subjected to a large external force (for example, the improper operation of the user is serious), the over-torque protection member 4 can block the external torque when the external torque applied to the faucet 2 is greater than the preset value, so as to avoid the excessive external torque from acting on the output shaft 301 of the driving member 3, thereby reliably protecting the electric motor.

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.

[0106] 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.

[0107] In other embodiments, the number of reinforcing bars 6 may be two, three, five, etc.

[0108] Furthermore, the rotation protection structure also includes a limiting mechanism, which is set 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.

[0109] 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.

[0110] 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.

[0111] 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.

[0112] The limiting hole 7 is suitable for installing the column 5 to pass through, and in the embodiment, two limiting holes 7 are formed to make two columns 5 pass through one limiting hole 7 respectively. The faucet 2 has a water adding position (one rotation amplitude limit position) and an initial position (another rotation amplitude limit position), and correspondingly, the limiting hole 7 has a first limiting edge 701 and a second limiting edge 702, and in the embodiment, the first limiting edge 701 corresponds to the water adding position of the faucet 2, and the second limiting edge 702 corresponds to the initial position of the faucet 2.

[0113] During the rotation of the faucet 2, when the column 5 abuts against the first limiting edge 701, the faucet 2 is rotated to the water adding position, so that the faucet 2 can be stopped in time when it is rotated to the water adding position, and when the column 5 abuts against the second limiting edge 702, the faucet 2 is rotated to the initial position, so that the faucet 2 can be stopped in time when it is rotated to the initial position, thereby improving the accuracy of the rotation amplitude of the faucet and improving the reliability of the product.

[0114] In addition, since the outer wall of the column 5 is provided with the rib 6, when the column 5 abuts against the first limiting edge 701, the rib 6 abuts against the first limiting edge 701, that is, the column 5 abuts against the first limiting edge 701 through the rib 6, and when the column 5 abuts against the second limiting edge 702, the rib abuts against the second limiting edge 702, that is, the column 5 abuts against the second limiting edge 702 through the rib 6.

[0115] Further, the limiting hole 7 is an arc-shaped long hole.

[0116] In the embodiment, the limiting hole 7 is an arc-shaped long hole, so that the structural form of the limiting hole 7 is adapted to the rotation path of the column 5, and the structure is more compact, which is beneficial to the optimization of the product structure. Specifically, the arc of the limiting hole 7 matches the rotation arc of the column 5.

[0117] Further, the over-torque protection member 4 includes a cover body 401, a first component 402, a second component 403 and an elastic member 404, the cover body 401 is fixed with the first component 402, the second component 403 is arranged in the cover body 401, the elastic member 404 is arranged in the cover body 401, one end of the elastic member 404 abuts against the cover body 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 with the output shaft 301, and the end of the second component 403 away from the first component 402 is connected with the faucet 2.

[0118] As shown in Figures 3-4 , Figures 13-17 , the over-torque protection member 4 is a kind of clutch structure. The over-torque protection member 4 includes 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 in parallel with the axial direction of the water outlet column 1.

[0119] 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.

[0120] 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.

[0121] 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.

[0122] 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.

[0123] like Figure 16 As shown, this is the bottom structure of the first component 402, as follows: Figure 17As shown, it is the top structure of the second component 403. The first component 402 is provided with the first component engagement teeth 408 towards the bottom surface of the second component 403, and the second component 403 is provided with the second component engagement teeth 409 towards the top surface of the first component 402. The engagement surface between the first component 402 and the second component 403 is a bevel, i.e. both sides of the first component engagement teeth 408 and the second component engagement teeth 409 are bevels, which are arranged at an acute angle or an obtuse angle with the axial direction of the over-torque protector 4, as shown in the middle toothed structure. Figure 15

[0124] During the rotation of the second component 403 driven by the first component 402, the first component 402 will always provide the second component 403 with an axial force pushing the second component 403 away (the pushing force to move away), which is relative, i.e. the first component 402 pushes the second component 403 away, and the second component 403 also pushes the first component 402 away, and if the pushing force is too large, the first component 402 and the second component 403 will move away from each other.

[0125] When the axial pushing force is not large (only 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 engagement surfaces of the first component engagement teeth 408 and the second component engagement teeth 409 are in contact, the first component 402 will drive the second component 403 to rotate, and when the axial pushing force is large (the external force torque applied to the faucet 2 is greater than the preset value), the axial pushing force overcomes the pressure of the elastic member 404 on the second component 403, the first component 402 and the second component 403 will be separated, and the first component 402 and the second component 403 will slip, thereby avoiding the transmission of the external force torque applied to the faucet 2 to the output shaft 301 of the driving member 3, thereby forming reliable protection for the driving member 3.

[0126] In addition, the tooth tips of the first component engagement teeth 408 and the second component engagement teeth 409 are flat, and when the first component 402 and the second component 403 are separated, the tooth tips of the first component engagement teeth 408 and the second component engagement teeth 409 can contact each other, and the first component 402 and the second component 403 will slip.

[0127] As shown in the figure, in this embodiment, the connecting plate 201 has a mounting groove 202, which is arranged at the center position of the connecting plate 201, and the mounting groove 202 is concave downward, the inner dimension of the mounting groove 202 matches the outer dimension of the cover body 401, and the cover body 401 is arranged in the mounting groove 202, so that the setting position of the over-torque protector 4 is more stable. Figure 4

[0128] ​​The bottom of the installation 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 in the assembly hole 203, so as to connect the second component 403 with 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 is fixed with the assembly hole 203 at least in the rotating direction.

[0129] The side of the connecting plate 201 facing the water outlet column 1 is provided with a rotating shaft 206. The water outlet column 1 is provided with a fixing plate 101, which is formed with a mounting hole. The rotating shaft 206 is inserted into the mounting hole and gap-fitted with the mounting hole. By inserting the rotating shaft 206 of the connecting plate 201 into the mounting hole of the fixing plate 101 and gap-fitting the rotating shaft 206 with the mounting hole, 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 force, thereby further improving the reliability of the structure. In this embodiment, the mounting hole is a through hole to facilitate structural connection.

[0130] The embodiment also provides a rotation protection system applied to the rotation protection structure. The rotation protection system comprises a control member and a position detection mechanism. The position detection mechanism is arranged at at least one rotation amplitude limit position of the faucet 2. The control member is electrically connected to the position detection mechanism and the driving member 3 of the rotation protection structure.

[0131] In addition to limiting the rotation amplitude of the faucet 2 relative to the water outlet column 1 by the limiting mechanism of the rotation protection structure, the position detection mechanism can also be used to strengthen the detection and limitation of the rotation amplitude of the faucet 2, thereby further improving the reliability of the structure. The position detection mechanism is arranged at at least one rotation amplitude limit position of the faucet 2, i.e., the position detection mechanism is arranged at the initial position of the faucet 2, or the water filling position, or both the initial position and the water filling position.

[0132] In this embodiment, the position detection mechanism is arranged at the water filling position of the faucet 2, so as to simplify the structure of the water outlet device and reduce the manufacturing cost.

[0133] The position detection mechanism comprises a detection member 8 and a triggering member 9. One of the detection member 8 and the triggering member 9 is arranged at the water outlet column 1, and the other is arranged at the faucet 2.

[0134] In the embodiment, the detecting member 8 is arranged at the upper portion of the water outlet column 1, and the triggering member 9 is arranged at the lower portion of the faucet 2 (i.e. the lower portion of the faucet seat 205). The detecting member 8 is an optical switch, and the triggering member 9 is a rib plate. When the faucet 2 is rotated to the water filling position, the rib plate is inserted between the emitting tube and the receiving tube of the concave optical switch and blocks the light therebetween, and the optical switch sends a signal to the control member. At this time, the faucet 2 has been rotated to the position.

[0135] In other embodiments, the detecting member 8 can be arranged at the lower portion of the faucet 2, and the triggering member 9 is arranged at the upper portion of the water outlet column 1. As long as the positions of the two members match, the triggering and detecting can be realized.

[0136] The embodiment also provides a water outlet device, which comprises the water outlet column 1, the faucet 2, and the rotation protection structure as described above. The faucet 2 is arranged at the top of the water outlet column 1 through the rotation protection structure.

[0137] When the user operates the faucet 2 improperly (forcibly rotates the faucet 2 or hinders the rotation of the faucet 2), if 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, so as to avoid the excessive external force torque acting on the shaft of the driving member 3 (motor), reliably protect the motor, and prevent the motor from being damaged. In this way, the adverse effects of improper operation of the user on the motor are eliminated, and the service life of the motor and the water outlet device is ensured. In addition, the limiting mechanism is arranged 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 amplitude of the faucet 2, so that the faucet 2 can be stopped in time when the faucet 2 is rotated to the water filling position and the initial position. In this way, the water outlet of the faucet 2 at the non-set position is avoided, the water spilling on the base or the table top is avoided, and the use safety of the water outlet device is ensured.

[0138] In the embodiment, the water outlet device is specifically an electric kettle. The water outlet device further comprises a kettle body 11 arranged on the base 10. The top of the kettle body 11 is provided with an opening, and the opening is detachably covered with a cover. The faucet 12 is arranged at the top of the water outlet column 1 and can be rotated, so that the faucet 12 is aligned with the opening at the top of the kettle body 11 in the water filling position, and the water filling process is realized. The control member and the like are further arranged in the base 10. The control member is used to control the operation of the driving member 3 and the position detecting mechanism. Of course, the water outlet device further comprises other structures and components possessed by the existing water outlet devices, which are not described herein.

[0139] In the embodiment, the lower portion of the faucet 2 is inserted into the water outlet column 1, so as to save the arrangement space, facilitate the structural connection of the rotation protection structure, facilitate the structural layout, and optimize the product appearance of the water outlet device.

[0140] The working process of the rotation protection structure in the water outlet device in the embodiment is described as follows:

[0141] When the faucet 2 needs to rotate relative to the water outlet column 1, the power output by the output shaft 301 of the driving part 3 drives the first part 402 to rotate, and since the first part 402 is engaged with the second part 403, the first part 402 drives the second part 403 to rotate, the second part 403 is fixed with the faucet 2 in the rotating direction, and the second part 403 drives the faucet 2 to rotate, thereby realizing the rotation of the faucet 2 relative to the water outlet column 1.

[0142] If the user forcibly rotates the faucet 2 or hinders the rotation of the faucet 2 during the rotation of the faucet 2 relative to the water outlet column 1, the pushing force of the meshing teeth between the first part 402 and the second part 403 will make the first part 402 and the second part 403 move away from each other, so that the first part 402 and the second part 403 are separated, thereby blocking the transmission of excessive external torque to the motor output shaft.

[0143] 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 is rotated to the water outlet position, and at the same time, the trigger piece 9 of the in-place detection mechanism triggers the detection piece 8; when the mounting column 5 abuts against the second limiting edge 702, the faucet 2 is rotated to the initial position.

[0144] It should be noted that the rotation parameter of the driving part 3 can also be controlled by the control part to control the rotation position of the faucet 2, thereby further improving the accuracy of the rotation amplitude control of the faucet 2.

[0145] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and variations can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and variations fall within the scope defined by the appended claims.
