[0026] The utility model drives the rotating piece 31 to abut against the abutting piece 22 by the driving motor 33 of the locking mechanism 3, so that the abutting piece 22 cannot slide, thereby keeping the cover 2 and the kettle body 1 locked. The driving motor 33 drives the abutting rod 321 on the linkage gear 32 to abut against the rotating knob 23, so that the cover 2 can be closed to prevent the cover 2 from opening. By sealing the cover 2 and the kettle body 1 and the cover 2 self-sealing, the cover 2 can be prevented from being accidentally opened in public places, which has better safety. At the same time, since the opening and closing of the cover 2 can be achieved by electronic control, pre-brewed tea can be placed in public places to prevent unauthorized drinking.

[0027] As an embodiment provided by the present utility model, Figure 4 and Figure 5 As shown, it also includes a movable rod 4, a liquid channel 24 is opened inside the lower shell body 21, one end of the liquid channel 24 is connected to the interior of the kettle body 1, and the other end is connected to the outside, the movable rod 4 is movably connected to the lower shell body 21, and one end of the movable rod 4 passes through and extends to the outside of the lower shell body 21, and the end of the movable rod 4 located outside the lower shell body 21 is fixedly installed with a sealing gasket 41, which can abut against one end of the liquid channel 24, thereby sealing one end of the liquid channel 24 to prevent the liquid inside the kettle body 1 from flowing out, and a waist-shaped hole is opened on one side of the rotating knob 23, one end of the movable rod 4 is inserted into the waist-shaped hole, a key slot is provided on the top of the movable rod 4, and the hole pitch of the waist-shaped hole is smaller than the bottom diameter of the movable rod 4. Therefore, when the rotating knob 23 is rotated downward, it can abut against the movable rod 4 and push the movable rod 4 to move downward, thereby separating the sealing gasket 41 from the liquid channel 24, and the liquid in the kettle body 1 can flow out through the liquid channel 24.

[0028] As a further embodiment provided by the present invention, Figure 4 As shown, the locking mechanism 3 also includes a driving gear 34, which is fixedly mounted on the output end of the driving motor 33, and a linkage gear 32 is movably arranged on the outer wall of the movable rod 4.

Specifically, the slide groove 43 is an "L"-shaped structure. A slider 322 is provided at the axis center of the linkage gear 32. The linkage gear 32 can be connected to the inside of the slide groove 43 through the slider 322. Since the slide groove 43 is an "L"-shaped structure, when the linkage gear 32 is installed, it is necessary to first connect the linkage gear 32 to the inside of the slide groove 43 through the slider 322. When the linkage gear 32 keeps rotating under the drive of the driving gear 34, the slider 322 first slides in the slide groove 43. When the slider 322 slides to the end of the slide groove 43, the slider 322 abuts against the slide groove 43. At this time, the movable rod 4 can be driven to rotate by the linkage gear 32.

[0031] As a further embodiment provided by the present invention, Figure 5 As shown, a limiting rod 27 is fixedly installed on the inner wall of one side of the lower shell 21, and the linkage gear 32 is driven to rotate by the driving motor 33, and the linkage gear 32 drives the abutment rod 321 to rotate. The abutment rod 321 can abut against the limiting rod 27, and the two ends of the abutment rod 321 respectively pass through the two sides of the linkage gear 32. The upper end of the abutment rod 321 abuts against the rotating knob 23, and the lower end of the abutment rod 321 abuts against the limiting rod 27, which can provide support force for the abutment rod 321 to prevent the abutment rod 321 from deformation when the rotation of the limiting rotating knob 23 is restricted.

[0032] As a further embodiment provided by the present invention, it also includes an upper shell 5, a display screen 6 is fixedly installed inside the upper shell 5, and the display screen 6 maintains data connection with the circuit board 51. A control board 28 is fixedly installed inside the protective cover 26, and the control board 28 is provided with basic electronic components such as a Bluetooth module, a control module, and a battery.

[0033] Working principle:

[0034] Before use, the staff first brews tea in the pot body 1;

[0035] After brewing is completed, the cover 2 is connected to the kettle body 1, and then the driving motor 33 is controlled by the mobile phone to drive the linkage gear 32 and the movable rod 4 to rotate, locking the abutment piece 22 and the rotating knob 23, thereby locking the kettle body 1 and the cover 2, as well as the inside and outside of the cover 2, to prevent unauthorized use;

[0036] After the user scans the QR code on the display screen 6 with a smart phone and makes payment;

[0037] The driving motor 33 drives the driving gear 34 to keep rotating. The rotation of the driving gear 34 drives the linkage gear 32 to rotate. The abutment rod 321 rotates synchronously with the linkage gear 32, thereby separating the abutment rod 321 from the limit rod 27. At this time, the rotary knob 23 is unlocked. At this time, the rotating block 42 abuts against one of the contact switches 52, providing a rotation position signal of the linkage gear 32, and the user can drink the tea in the kettle body 1. While driving the linkage gear 32 to rotate, the movable rod 4 is driven to keep rotating. The rotation of the movable rod 4 synchronously drives the rotating piece 31 to rotate. When the rotating piece 31 rotates, the rotating piece 31 can be separated from the abutment piece 22. At this time, the abutment piece 22 can slide inside the lower shell 21. At this time, the cover body 2 and the kettle body 1 are unlocked. At this time, the liquid inside the kettle body 1 can be replenished;

[0038] After the replenishment is completed, it is necessary to re-lock the bottle, and the driving motor 33 drives the linkage gear 32 to continue to rotate, so that the rotating piece 31 is kept in contact with the abutting piece 22, and the rotating block 42 is in contact with another contact switch 52. At this time, the abutting rod 321 is separated from the limit rod 27, so that only the abutting piece 22 can be locked. At the same time, the linkage gear 32 can be driven by the driving motor 33 to continue to rotate, so that the abutting rod 321 is in contact with the limit rod 27, and the rotating piece 31 is separated from the abutting piece 22. At this time, the rotating block 42 is in contact with another contact switch 522, so that the rotary knob 23 can be locked alone, while the abutting piece 22 is not locked, so that the beverage can be replenished in the kettle body 1.

[0039] Finally, the linkage gear 32 is driven to rotate by the driving motor 33, so that the abutment rod 321 and the limit rod 27 remain in abutment, while the rotating piece 31 abuts against the abutment piece 22, and the rotating block 42 abuts against one of the contact switches 52. At this time, the abutment piece 22 and the rotating knob 23 can be locked at the same time.

[0040] The elastic coefficient of the compression spring 32 mentioned herein meets the technical requirements of the technical solution of the present utility model.

[0041] Those skilled in the art will appreciate that other similar connection methods can also implement the present invention, such as welding, bonding, or screwing.

[0042] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
