Specifically, the driving part 3 adopts a motor, and the driving part 3 has an output shaft 301. The output shaft 301 is arranged relative to the axial offset of the water outlet column 1, i.e. the output shaft 301 is arranged on one side of the water outlet column 1 in the axial direction, and the axial direction of the output shaft 301 does not coincide with the axial direction of the water outlet column 1, so as to leave more space in the water outlet column 1 and the faucet 2, facilitating the arrangement of water inlet pipe and electric wire and other components.

[0057] As shown in the figure, Figure 1As shown, the faucet 2 comprises a faucet cover 202 and a faucet base 203, the faucet cover 202 covers the top of the faucet base 203, and the faucet cover 202 and the faucet base 203 are connected by snap-fit, forming an integral structure.

[0060] Further, the transmission mechanism comprises a first transmission member 4, the first transmission member 4 is connected with the output shaft 301, and the first transmission member 4 is engaged with the faucet 2.

[0061] As shown, Figures 2-4 The transmission mechanism comprises a first transmission member 4, the first transmission member 4 is driven by the output shaft 301 of the drive member 3, in this embodiment, the first transmission member 4 is indirectly connected with the output shaft 301, and the first transmission member 4 is engaged with the faucet 2 to drive the faucet 2 to rotate. This transmission structure is reliable, high in firmness, and not easy to damage, which is conducive to ensuring the service life of the water outlet device.

[0062] Further, the faucet 2 is provided with a faucet engaging portion 201, the faucet engaging portion 201 is arranged close to the inner wall of the faucet 2, the first transmission member 4 has a transmission engaging portion 401, and the faucet engaging portion 201 is engaged with the transmission engaging portion 401.

[0063] As shown, Figure 11 The faucet 2 is provided with a connecting plate 204, the plane of the connecting plate 204 is perpendicular to the rotation shaft of the faucet 2, the faucet engaging portion 201 is arranged on the connecting plate 204, the faucet engaging portion 201 is a segment of engaging tooth structure, and the faucet engaging portion 201 is arranged close to the inner wall of the faucet 2 relative to the rotation shaft of the faucet 2, so as to cooperate with the biasing of the drive member 3, and does not hinder the installation of other structures in the faucet 2.

[0064] As shown, Figure 7As shown, the first transmission component 4 is a cylindrical structure. A transmission engagement part 401 is provided at the bottom of the first transmission component 4. The transmission engagement part 401 is a gear structure. The axial direction of the transmission engagement part 401 is collinear with the axial direction of the first transmission component 4. The transmission engagement part 401 meshes with the faucet engagement part 201.

[0065] Furthermore, the rotation drive structure also includes a mounting mechanism, which includes a bracket 5. At least a portion of the bracket 5 is placed inside the faucet 2, and the drive component 3 is fixed to the water column 1 via the bracket 5.

[0066] like Figures 2-4 As shown, the installation mechanism includes a bracket 5, and the driving component 3 is indirectly connected to the bracket 5 to fix the driving component 3 to the water outlet column 1 via the bracket 5. Figure 10 As shown, a support connecting column 502 is provided at the bottom of the support 5, and a water outlet column connecting hole 101 is provided inside the water outlet column 1. The support connecting column 502 and the water outlet column connecting hole 101 have the same cross-sectional shape perpendicular to the axial direction, as shown. Figure 12 As shown, the water outlet column connection hole 101 is located at the center of the water outlet column 1. The bracket connecting column 502 is adapted to be inserted into the water outlet column connection hole 101 so that the bracket 5 and the water outlet column 1 are fixed in the horizontal rotation direction. In this embodiment, the cross-sectional shape of the bracket connecting column 502 perpendicular to the axial direction is elliptical, and the bracket connecting column 502 is an elliptical cylinder. The shape and size of the water outlet column connection hole 101 match those of the bracket connecting column 502, and it is an elliptical hole.

[0067] Furthermore, in order to further improve the reliability of the structure, the bracket 5 is also fastened to the water outlet column 1 with bolts, so that the bracket 5 is fixed to the water outlet column 1.

[0068] Furthermore, part of the structure of the first transmission component 4 is disposed inside the bracket 5, and the side wall of the bracket 5 is formed with a hollow structure. The transmission engagement part 401 engages with the faucet engagement part 201 through the hollow structure.

[0069] like Figure 10 As shown, the bracket 5 has a mounting hole 505, into which the lower part of the first transmission member 4 is inserted. To achieve the offset setting of the drive member 3, the axial direction of the mounting hole 505 is offset from the axial direction of the water outlet column 1. Figure 7 As shown, in order to further improve assembly reliability, a first transmission shaft 402 is also provided at the bottom of the first transmission component 4. The first transmission shaft 402 is located at the center of the transmission meshing part 401. A positioning hole 503 is provided at the bottom of the mounting hole 505. The first transmission shaft 402 is suitable for insertion into the positioning hole 503 to ensure the rotation accuracy of the first transmission component 4 and prevent the first transmission component 4 from shaking.

[0070] The side wall of the support 5 is shaped with a hollow structure, which is specifically arranged on the side wall of the mounting hole 505. After the lower part of the first transmission member 4 is inserted into the mounting hole 505, part of the transmission engagement part 401 of the first transmission member 4 is exposed through the hollow structure, so that the transmission engagement part 401 is engaged with the faucet engagement part 201, and the structure is conveniently connected. The hollow structure is specifically an empty slot 501. The inside and outside of the mounting hole 505 are communicated through the empty slot 501. The size of the empty slot 501 is not specifically limited, as long as it does not affect the engagement between the transmission engagement part 401 and the faucet engagement part 201.

[0071] Further, the transmission mechanism further comprises an over-torque protection assembly. The over-torque protection assembly is arranged in the faucet 2 and between the output shaft 301 and the faucet 2. When the external force torque applied to the faucet 2 is greater than a preset value, the over-torque protection assembly blocks the external force torque.

[0072] The over-torque protection assembly is part of the transmission mechanism. 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 user's improper operation is not serious), the over-torque protection assembly is used for transmission, 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 user's improper operation is relatively serious), at this time, when the external force torque applied to the faucet 2 is greater than a preset value, the over-torque protection assembly can block the external force torque, so as to avoid the excessive external force torque acting on the output shaft 301 of the driving member 3 and form reliable protection for the motor. Through structural design, the setting and correspondence of the external force torque preset value can be realized, and the external force torque preset value is related to the specific structure of the over-torque protection assembly.

[0073] Further, the over-torque protection assembly comprises the first transmission member 4, the first pressing plate 6, the second transmission member 7 and the elastic member 8. The first pressing plate 6 is fixed with the water column 1, the first pressing plate 6 is covered with the first transmission member 4 and forms an internal containing space, the second transmission member 7 and the elastic member 8 are arranged in the containing space, one end of the elastic member 8 abuts against the first pressing plate 6, the other end of the elastic member 8 abuts against the second transmission member 7 towards the first transmission member 4, so that the second transmission member 7 and the first transmission member 4 are engaged, and the second transmission member 7 is further connected with the output shaft 301.

[0074] The over-torque protection assembly is a kind of clutch structure. The over-torque protection assembly comprises the first transmission member 4, the first pressing plate 6, the second transmission member 7 and the elastic member 8. The first transmission member 4, the first pressing plate 6 and the second transmission member 7 are coaxial, and the axial directions of the three are arranged to deviate from the axial direction of the water column 1, and the axial directions of the first transmission member 4, the first pressing plate 6 and the second transmission member 7 are parallel to the axial direction of the water column 1.

[0075] The first pressing plate 6 is fixed with the water outlet column 1. Specifically, the first pressing plate 6 is provided with two butt joint columns 601, and the two butt joint columns 601 are symmetrically arranged relative to the axial direction of the first pressing plate 6. Correspondingly, the bracket 5 is provided with two bracket mounting columns 504, the bracket mounting column 504 corresponds to the position and size of the butt joint column 601, and the bracket mounting column 504 and the butt joint column 601 can be fastened by a fastener (such as a bolt) to realize the fixation of the first pressing plate 6 and the bracket 5, and the bracket 5 is fixed with the water outlet column 1, thereby realizing the fixation of the first pressing plate 6 and the water outlet column 1.

[0076] After the first pressing plate 6 is connected with the first transmission member 4, an accommodation space is formed in the interior of the two, and the second transmission member 7 and the elastic member 8 are arranged in the accommodation space. Figure 6 As shown in FIG. 4, the first transmission member 4 is provided with a first transmission member connecting groove 405, the opening of the first transmission member connecting groove 405 faces upward, and the cross-sectional shape of the first transmission member connecting groove 405 perpendicular to the axial direction of the first transmission member 4 is oval, so the first transmission member connecting groove 405 is an oval groove. Figure 8 As shown in FIG. 4, the bottom of the second transmission member 7 is provided with a second transmission member connecting column 703, the shape and size of the second transmission member connecting column 703 match the first transmission member connecting groove 405, the second transmission member connecting column 703 is suitable for being inserted into the first transmission member connecting groove 405 to realize the fixation of the first transmission member 4 and the second transmission member 7 in the horizontal rotation direction, but the first transmission member 4 and the second transmission member 7 are not fixed in the axial direction, and the first transmission member 4 and the second transmission member 7 can be close to or away from each other in the axial direction.

[0077] In the accommodation space, the bottom of the first pressing plate 6 has an assembly column 603 protruding toward the second transmission member 7 (downward), the interior of the assembly column 603 is a through hole structure, the top of the second transmission member 7 is provided with an insertion column 705, and the insertion column 705 is suitable for being inserted into the through hole of the assembly column 603. The elastic member 8 is sleeved on the outer wall of the assembly column 603, one end of the elastic member 8 abuts against the first pressing plate 6, and the other end of the elastic member 8 abuts against the second transmission member 7 toward the first transmission member 4, so as to press the second transmission member 7 and the first transmission member 4 and keep the second transmission member 7 and the first transmission member 4 in the engaged state. The elastic member 8 adopts a spring, and in the accommodation space, the elastic member 8 is in a compressed state.

[0078] The second transmission member 7 is provided with a second transmission member connecting groove 704 in the plug-in column 705, and the output shaft 301 of the driving member 3 is adapted to be inserted into the second transmission member connecting groove 704. The cross-sectional shape of the second transmission member connecting groove 704 perpendicular to the axial direction is oval, and the cross-sectional shape of the output shaft 301 perpendicular to the axial direction matches the same. After the output shaft 301 is adapted to the second transmission member connecting groove 704, the output shaft 301 can drive the second transmission member 7 to rotate together. The second transmission member 7 is engaged with the first transmission member 4, and the second transmission member 7 drives the first transmission member 4 to rotate. The first transmission member 4 is engaged with the faucet 2, and the faucet 2 is further driven to rotate relative to the water outlet column 1.

[0079] In order to realize the over-torque protection of the motor by the over-torque protection assembly, the engagement surface of the first transmission member 4 and the second transmission member 7 is a bevel sawtooth surface.

[0080] As shown in FIG. 1, the first transmission member 4 is provided with a first over-torque engagement part 403 on the surface facing the second transmission member 7, and a first over-torque engagement groove 404 is formed between adjacent first over-torque engagement parts 403. Similarly, the second transmission member 7 is provided with a second over-torque engagement part 701 on the surface facing the first transmission member 4, and a second over-torque engagement groove 702 is formed between adjacent second over-torque engagement parts 701. Figure 6 As shown in FIG. 1, the first transmission member 4 is provided with a first over-torque engagement part 403 on the surface facing the second transmission member 7, and a first over-torque engagement groove 404 is formed between adjacent first over-torque engagement parts 403. Similarly, the second transmission member 7 is provided with a second over-torque engagement part 701 on the surface facing the first transmission member 4, and a second over-torque engagement groove 702 is formed between adjacent second over-torque engagement parts 701. Figure 8 The engagement surface between the first over-torque engagement part 403 and the second over-torque engagement part 701 is a bevel surface, that is, the two sides of the first over-torque engagement part 403 and the second over-torque engagement part 701 are bevel surfaces, and the bevel surface is arranged at an acute angle or an obtuse angle with the axial direction of the first transmission member 4 and the second transmission member 7.

[0081] In the process of driving the first transmission member 4 to rotate by the second transmission member 7, the second transmission member 7 always provides the first transmission member 4 with an axial force pushing the first transmission member 4 away (a pushing force to move away), and the pushing force is relative, that is, the second transmission member 7 pushes the first transmission member 4 away, and the first transmission member 4 also pushes the second transmission member 7 away. If the pushing force is too large, the first transmission member 4 and the second transmission member 7 will move away from each other.

[0082] 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 surface of the first over-torque engagement part 403 and the second over-torque engagement part 701 is in contact, and the second transmission member 7 drives the first transmission member 4 to rotate. 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 8 on the second transmission member 7, the elastic member 8 is further compressed, the first transmission member 4 and the second transmission member 7 are separated, and the first transmission member 4 and the second transmission member 7 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.

[0083] In addition, the tooth tips of the first over-torque engaging portion 403 and the second over-torque engaging portion 701 are flat surfaces, and when the first transmission member 4 and the second transmission member 7 are separated, the tooth tips of the first over-torque engaging portion 403 and the second over-torque engaging portion 701 can contact each other, and the first transmission member 4 and the second transmission member 7 can slip.

[0084] In addition, in order to achieve reliable fixation of the driving member 3, the driving member 3 is further fixed to the water outlet column 1 by the first pressing plate 6 and the second pressing plate 9. As shown in Figures 2-5 the second pressing plate 9 is arranged on the side of the first pressing plate 6 away from the support 5, the second pressing plate 9 is sleeved on the outside of the upper part of the driving member 3, the first pressing plate 6 is sleeved on the outside of the lower part of the driving member 3, and after the first pressing plate 6 and the second pressing plate 9 are matched, an internal cavity is formed, and the main part of the driving member 3 (except the output shaft 301) is arranged in the cavity.

[0085] The outer wall of the second pressing plate 9 is provided with two ear plates 901, the two ear plates 901 are symmetrically arranged with respect to the axial direction of the second pressing plate 9, the first pressing plate 6 is further provided with two first pressing plate mounting columns 602, the positions of the first pressing plate mounting columns 602 correspond to the positions of the ear plates 901, and the first pressing plate mounting columns 602 and the ear plates 901 can be fixed by fasteners (such as bolts), so as to achieve fixation of the first pressing plate 6 and the second pressing plate 9, fixation of the first pressing plate 6 and the water outlet column 1, fixation of the main part of the driving member 3 (except the output shaft 301) and the water outlet column 1, fixation of the second pressing plate 9, the main part of the driving member 3 (except the output shaft 301), the first pressing plate 6, and the support 5 to the water outlet column 1, and formation of an integral whole, and when the faucet 2 rotates relative to the water outlet column 1, the second pressing plate 9, the main part of the driving member 3 (except the output shaft 301), the first pressing plate 6, and the support 5 do not rotate.

[0086] The installation process of the rotating driving structure of the embodiment will be briefly described below:

[0087] Firstly, the first pressing plate 6, the driving member 3, and the second pressing plate 9 can be pre-assembled to form an integral structure, i.e., a motor assembly;

[0088] The faucet seat 203 is inserted into the water outlet column 1, the support 5 is placed into the faucet seat 203 from the top of the faucet seat 203, the support connecting column 502 of the support 5 is inserted into the water outlet column connecting hole 101 of the water outlet column 1, and the support 5 and the water outlet column 1 are fixed by bolts;

[0089] Then, the first transmission member 4 is installed into the mounting hole 505 of the support 5, the first transmission rotating shaft 402 is inserted into the positioning hole 503, and then the second transmission member 7 is installed into the first transmission member 4, the second transmission member connecting column 703 is inserted into the first transmission member connecting groove 405, and the first over-torque engaging portion 403 and the second over-torque engaging portion 701 are engaged;

[0090] The elastic member 8 is sleeved on the assembling column 603 of the first pressing plate 6, the upper end of the elastic member 8 abuts against the first pressing plate 6, the lower end of the elastic member 8 abuts against the second transmission member 7, the first pressing plate 6 is fixed to the support 5 by bolts, and thus the installation is completed.

[0091] After the rotating driving structure is installed, the whole rotating driving structure is offset in the axial direction of the water outlet column 1, occupies less space in the water outlet column 1 and the internal space of the faucet 2, and can leave a larger space for arranging the water inlet pipe and the electric wire, thereby facilitating the installation of the water inlet pipe and the electric wire.

[0092] The embodiment also provides a water outlet device, which comprises the water outlet column 1, the faucet 2 and the rotating driving structure.

[0093] The water outlet device, the output shaft 301 of the driving member 3 is arranged offset relative to the axial direction of the water outlet column 1, so that the whole rotating driving structure is arranged offset in the water outlet column 1, that is, the whole rotating driving structure is arranged close to the inner wall of one side of the water outlet column 1, so that the rotating driving structure is arranged very compactly and reasonably, the space for arrangement is saved, the internal space of the water outlet column 1 is occupied less, and the arrangement space of the water inlet pipe and the electric wire and other structures is avoided, so that the internal space of the water outlet column 1 is optimized significantly, and the layout of the water inlet pipe and the electric wire is facilitated.

[0094] In addition, when the user operates 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 assembly can block the external force torque, so as to avoid the excessive external force torque from acting on the output shaft 301 of the driving member 3 (the motor), reliably protect the motor, prevent the motor from being damaged easily, eliminate the adverse effects of improper operation of the user on the motor, and ensure the service life of the motor and the water outlet device.

[0095] 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, the opening is detachably covered with a cover body, and a faucet 12 is arranged on the top of the water outlet column 1, the faucet 12 can rotate, so that the faucet 12 is aligned with the top opening of the kettle body 11 in a water filling position, and the water filling process is realized. Control members and the like are further arranged in the base 10, and the control members are used to control the operation of the driving member 3 and the like. Of course, the water outlet device further comprises other structures and components possessed by existing water outlet devices, which will not be described herein.

[0096] In the embodiment, the lower part 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 rotating driving structure, facilitate the structural layout, and optimize the product appearance of the water outlet device.

[0097] The working process of the rotating driving structure in the water outlet device is described below in combination with the drawings:

[0098] 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 member 3 drives the second transmission member 7 to rotate. Since the second transmission member 7 is in meshing connection with the first transmission member 4, the second transmission member 7 drives the first transmission member 4 to rotate. The first transmission member 4 is in meshing connection with the faucet 2, and the first transmission member 4 drives the faucet 2 to rotate, thereby realizing the rotation of the faucet 2 relative to the water outlet column 1.

[0099] 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 second transmission member 7 and the first transmission member 4 can make the second transmission member 7 and the first transmission member 4 move away from each other, so that the second transmission member 7 and the first transmission member 4 are separated, thereby blocking the transmission of excessive external force torque to the motor output shaft.

[0100] Although the embodiments of the utility model are described in combination with the drawings, those skilled in the art can make various modifications and changes without departing from the spirit and scope of the utility model, and such modifications and changes all fall within the scope defined by the appended claims.
