More specifically, in the embodiment, when the second magnetic element 330 rotates clockwise around the axis of the upright post 310 along with the rotating head 320, and the second magnetic element 330 moves to the vicinity of the first magnetic element 230, the first magnetic element 230 can be driven to drive the sliding cover 220 to slide relative to the cover main body 210, and when the rotating head 320 moves to the water outlet 321 just aligned with the water inlet 211, the first magnetic element 230 also drives the sliding cover 220 to open the water inlet 211, and conversely, when the water is full, the rotating head 320 rotates counterclockwise around the axis of the upright post 310, so that the second magnetic element 330 drives the first magnetic element 230 to move in the opposite direction, thereby driving the sliding cover 220 to automatically close the water inlet 211.

Therefore, the electric kettle provided by the invention only needs to control the water inlet tap 300 to move relative to the kettle body 100, so that the water outlet 321 is aligned with the water inlet 211, the sliding cover 220 can open the water inlet 211 and add water into the water storage cavity 110, and after the water is filled, the water inlet tap 300 only needs to be controlled to move relative to the kettle body 100, so that the water outlet 321 is far away from the water inlet 211, and the sliding cover 220 can cover and seal the water inlet 211, namely, the driving component 500 is only needed to be controlled by the control unit, so that the rotating head 320 is driven to rotate relative to the upright column 310, the opening and closing actions of the water inlet 211 can be simultaneously realized, the process of independently opening and closing the kettle cover 200 is omitted, the process of manually driving the rotating head 320 to rotate is also omitted, the process of boiling water in the electric kettle is greatly simplified, and the user experience is optimized.

Further, the cover body 210 includes an upper cover 212 and a lower cover 213, wherein the upper cover 212 is connected with the lower cover 213 and encloses to form an accommodating cavity 214, the water inlet 211 is communicated with the accommodating cavity 214, and the sliding cover 220 is disposed in the accommodating cavity 214 and slidably engaged with the upper cover 212. Specifically, the upper cover 212 includes an upper cover body 2121 connected to the lower cover 213, and two slide ways 2122 fixedly connected to the upper cover body 2121, the two slide ways 2122 are disposed on a side surface of the upper cover body 2121 facing the accommodating cavity 214, the sliding cover 220 is located between the two slide ways 2122 and slidably fits with the two slide ways 2122, and the sliding cover 220 can slide along the slide ways 2122 under the driving of the first magnetic element 230 until it is close to and covers the water inlet 211, or slide along the slide ways 2122 under the driving of the first magnetic element 230 until it is far from and opens the water inlet 211.

Further, the extension path of the slide 2122 coincides with the projection of the movement path of the second magnetic element 330 relative to the kettle body 100 in the horizontal plane. In this way, it is ensured that the movement path of the first magnetic element 230 coincides with the projection of the movement of the second magnetic element 330 in the horizontal plane, that is, the first magnetic element 230 can follow the movement of the second magnetic element 330 in the same direction.

More specifically, the second magnetic element 330 is preferably a permanent magnet, but may be another type of magnetic induction element, and is not limited herein.

In one embodiment, referring to fig. 7 to 12, the driving assembly 500 includes a first motor 510, a motor bracket 520, and a thumb wheel 530; the mast 310 includes a mast upper cover 311, a mast body 312, a pull rod shaft 313, and a boss 314. The column body 312 is a cylindrical housing, and is rotatably connected to the rotating head 320, the column upper cover 311 is fixedly connected to one end of the column body 312 close to the rotating head 320, the pull rod shaft 313 is fixedly disposed in the column body 312, an axis of the pull rod shaft 313 coincides with an axis of the column body 312, the shaft sleeve 314 is fixedly connected to the column upper cover 311 and is sleeved on an outer periphery of the pull rod shaft 313, preferably, the shaft sleeve 314 and the column upper cover 311 are integrally formed, that is, the column upper cover 311 is sleeved on an outer periphery of the pull rod shaft 313 through the shaft sleeve 314; the motor bracket 520 includes a bearing portion (not shown) and a rotating sleeve 522 connected to the bearing portion, the bearing portion is fixedly connected to the rotating head 320, the rotating sleeve 522 is sleeved on the periphery of the shaft sleeve 314, the first motor 510 is fixedly disposed on the bearing portion and electrically connected to the control unit, and preferably, the bearing portion and the rotating sleeve 522 are integrally formed; the thumb wheel 530 includes a rotating plate 531 and a sliding protrusion 532, one end of the rotating plate 531 is fixedly connected to the output shaft of the first motor 510, the other end is fixedly connected to the sliding protrusion 532, a sliding slot 3111 is further disposed on the upright post upper cover 311, the sliding slot 3111 extends along the radial direction of the pull rod shaft 313, and the sliding protrusion 532 extends into the sliding slot and forms a sliding abutting fit with the upright post upper cover 311.

Thus, as shown in fig. 9 to 10, when the control unit controls the first motor 510 to rotate clockwise, one end of the rotating plate 531 rotates around the output shaft of the first motor 510, since the other end of the rotating plate 531 abuts against the upright post upper cover 311 through the sliding protrusion 532 in a sliding manner, and the upright post upper cover 311 is fixed relative to the post body 312; since the motor bracket 520 for fixing the first motor 510 is sleeved on the outer circumference of the pull rod shaft 313 through the rotating sleeve column 522 and can rotate around the pull rod shaft 313 under the action of external force, the sliding protrusion 532 extends into the sliding slot 3111 to generate a reaction force with the upright post upper cover 311 during the rotation of the first motor 510, and the reaction force enables the motor bracket 520, the first motor 510 and the rotating plate 531 to rotate around the pull rod shaft 313 together, during the process, the sliding protrusion 532 can only rotate along with the output shaft of the first motor 510 in the sliding slot 3111 and can slide along the radial direction of the pull rod shaft 313 in the sliding slot 3111 while rotating, and since the first motor 510 is fixed on the motor bracket 520 and the motor bracket 520 is fixed relative to the rotating head 320, the rotation of the first motor 510 finally causes the rotating head 320 to rotate around the axis of the pull rod shaft 313, thereby realizing the function of automatically rotating the rotary head 320. On the contrary, when the control unit controls the first motor 510 to rotate counterclockwise, the control unit can drive the rotating head 320 to rotate reversely, which is not described herein again. It can be seen that the above-mentioned driving assembly 500 has a simple structure and high reliability, and the space occupied by the faucet 300 can be effectively reduced by using the dial wheel 530 as a force transmission member, so as to optimize the user experience.

In addition, a first notch 3141 is formed in the shaft sleeve 314, a second notch 5221 is formed in the rotary sleeve column 511, the other end of the rotating plate 531 can extend into the first notch 3141 from the second notch 5221, and the first notch 3141 and the second notch 5221 are mainly used for preventing the shaft sleeve 314 and the rotary sleeve column 511 from interfering with the thumb wheel in the process of thumb wheel movement, so that the space occupation required by the matching installation of the thumb wheel 530, the upright column upper cover 311 and the first motor 510 can be reduced. Of course, in other embodiments of the present invention, the driving assembly 500 may be omitted, and a solution that only relies on manual operation to rotate the rotating head 320 also falls within the protection scope of the present invention.

In addition, the electric kettle provided by the invention can manually control the water outlet of the water inlet pipe 700, and can also realize the water outlet control of the water inlet pipe 700 by other induction components or structural components, which is not limited herein.

In one embodiment, referring to fig. 13 to 15, the base 400 includes a panel 410, a bottom cover 420, a coupler assembly 430, a gravity sensor 440, and a guide assembly 450; wherein, the coupler assembly 430 is used for cooperating with the kettle body 100 and can form an electrical connection with the kettle body 100; the gravity sensor 440 is disposed below the coupler assembly 430, and is used for sensing the water storage amount in the water storage cavity 110; the guide member 450 is disposed between the coupler member 430 and the gravity sensor 440, and guides the coupler member 430 to move toward the gravity sensor 440. Thus, when the kettle body 100 is placed on the base 400, the gravity of the kettle body acts on the coupler assembly 430, the coupler assembly 430 is mounted on the guide assembly 450, and the guide assembly 450 can guide the coupler assembly 430 to smoothly move toward the gravity sensor 440.
