[0026] Please refer to Figures 1 to 5The cup cover in the figure is mainly designed with top cover 1, end cover 4, hand-screw part 5, middle cover 6, inner plug 7, rotating mechanism and other components. The design core of this case is to use the rotating mechanism to make the two components formed by the end cover 4 and the hand-screw part 5, the middle cover 6 and the inner plug 7 engage or separate with each other. When the correct fingerprint is entered, the two components engage so that the hand-screw part 5 and the middle cover 6 remain fixed to each other so that the hand-screw part 5 can unscrew the middle cover 6. When an incorrect fingerprint is entered or no fingerprint is entered, the two components are separated. When the hand-screw part 5 is rotated, the hand-screw part 5 and the middle cover 6 slide against each other so that the hand-screw part 5 cannot unscrew the middle cover 6, thereby ensuring the safety of drinking water.

[0027] The top cover 1 in the figure is a round hat-shaped structure as a whole, that is, the bottom is open and the interior is hollow, and the top has a through hole 11 structure, which makes it convenient for the collection part of the fingerprint collection circuit board 21 to be arranged at this position, so as to facilitate the collection of fingerprints. In order to fix the motor 32, motor 32, fixed plate 22 and other components in the cup cover, the bracket 12 structure can be designed accordingly. For sealing and installation, a sealing ring can be designed at the position of the through hole 11 so as to be sleeved on the collection part of the fingerprint collection circuit board 21. The fingerprint collection circuit board 21 is a prior art and is fixed on a fixed plate 22 at the same time, so that the motor 32 is controlled to stop or rotate the motor 32. The micro motor 32 used in the motor 32 is powered by the power supply in the cup cover. The rotating main shaft of the motor 32 is equipped with a bevel gear structure, and the matching rotating mechanism is also equipped with a bevel gear structure, thereby driving the rotating rod 33 in the rotating mechanism to rotate.

[0028] The main body of the end cover 4 in the figure is a disc-shaped structure, and a support 41 structure protruding outward is designed at the position where it is configured with the motor 32. The support 41 is hollow inside and is designed with an axial hole structure and an opening at the bottom, so that it is convenient to insert the rotating rod 33 and connect the two end shafts of the rotating rod 33 to the axial hole position.

[0029] The rotating mechanism in the figure is mainly designed with a rotating rod 33 and a cog rod 34. The rotating rod 33 is an axial rod structure, which is axially installed on the support 41 and is kept assembled with the rotating main shaft of the motor 32. The cog rod 34 is a J-shaped structure as a whole and is installed on the rotating rod 33. One end of the cog rod 34 is fixed on the rotating rod 33, and the other end has a tooth groove that meshes with the meshing teeth 61 on the middle cover 6; therefore, when the rotating rod 33 rotates, the cog rod 34 rotates a certain range with the rotating rod 33 as the center, so as to keep meshing or disengaging with the meshing teeth 61 of the middle cover 6.

[0030] The main body of the hand-turned member 5 in the figure is a sleeve-like structure, with both the top and bottom being open structures and the interior being hollow. The inner wall of the hand-turned member 5 is designed with a plurality of protrusions 51 in the lateral position, so that the protruding ring 62 at the corresponding position of the middle cover 6 is supported and limited, and the protruding ring 62 is located above the protruding buckle. The hand-turned member 5 and the end cover 4 are independently molded. In use, the hand-turned member 5 and the end cover 4 need to be combined together to form a component using existing technology such as ultrasonic welding, so that the two components keep rotating synchronously.

[0031] The middle cover 6 in the figure is a round hat-shaped structure with openings on the top and bottom and a hollow interior. The inner edge of the top has a plurality of meshing teeth 61 arranged in a ring, and the outer wall is provided with the above-mentioned convex ring 62. The above-mentioned meshing teeth 61 maintain a relative meshing or disengagement relationship with the cog rod 34.

[0032] The inner plug 7 in the figure is a conventional component, which is also independently molded from the middle cover 6. During use, the middle cover 6 and the inner plug 7 need to be combined together into an assembly using existing technology such as ultrasonic welding, so that the two components keep rotating synchronously.

[0033] As shown above, in the initial state, that is, when the fingerprint is not recorded, the cog rod 34 remains in a separated state with the meshing teeth 61. When the hand-turned part 5 is rotated, the hand-turned part 5 maintains relative rotation with the middle cover 6, that is, the hand-turned part 5 can only slip on the middle cover 6 and cannot drive the middle cover 6 to rotate; when the recorded fingerprint is wrong, the motor 32 will not work, thereby maintaining the original separated state, and the middle cover 6 will not rotate; when the correct fingerprint is recorded, the fingerprint collection circuit board 21 activates the motor 32. At this time, the rotating rod 33 drives the cog rod 34 to move counterclockwise to engage with the meshing teeth 61 of the middle cover 6, thereby linking the hand-turned part 5 and the end cover 4 as a component with the middle cover 6. At this time, when the hand-turned part 5 is rotated, the middle cover 6 will start to rotate, so that the cup cover can be taken out from the cup body.
