A telescopic window 111 cooperating with the clamping slider 13 is provided on the cup cover body 11, and the ring gear 16 can drive the clamping slider 13 to extend and retract in the telescopic window 111 by rotation.

[0026] A groove 202 is provided at the upper end of the cup body 2 to cooperate with the clamping slider 13 . The clamping slider 13 can cooperate with the groove 202 to prevent the cup cover body 11 from being separated from the cup body 2 .

[0027] During operation, the driving member 14 drives the sun gear 15 to rotate, the sun gear 15 drives the three planetary gears 17 to rotate, and the three planetary gears 17 simultaneously drive the ring gear 16 to rotate, and finally, under the action of the guide groove 161, the clamping slider 13 is driven to extend and retract, and the clamping slider 13 and the groove 202 are switched to the clamping state. Through the cooperation of the planetary gear assembly and the driving member 14, the rotational torque can be increased by reducing the planetary gear structure, so that the ring gear 16 can more smoothly control the contraction of the clamping slider 13 to achieve efficient lid opening.

[0028] The guide groove 161 is in an arc shape, and the distance between the inner wall of the guide groove 161 and the outer wall of the gear ring 16 gradually increases or decreases along the rotation direction of the gear ring 16 .

[0029] The arc-shaped arrangement allows the clamping slider 13 to extend and retract more smoothly.

[0030] A gear-mounted rotating member that cooperates with the planetary gear 17 is provided in the cup cover body 11 . The planetary gear 17 is sleeved on the upper end of the gear-mounted rotating member, and the planetary gear 17 can rotate relative to the gear-mounted rotating member.

[0031] By setting the gear mounting rotating member, the position of the planetary gear can be effectively positioned.

[0032] The guide drive portion is provided with an arc-shaped guide groove 162 for avoiding air with the gear mounting rotating member. By providing the arc-shaped guide groove 162 , the stability of the rotation of the gear ring 16 can be effectively improved by cooperating with the gear mounting rotating member.

[0033] A convex ring 171 is provided on the lower end surface of the planetary gear 17 . The provision of the convex ring 171 can effectively reduce the friction between the lower end surface of the planetary gear 17 and the upper end surface of the ring gear 16 .

[0034] The gear mounting rotating part includes a rotating connecting column 18 and a rotating mounting cylinder 19. The rotating connecting column 18 is arranged in the rotating mounting cylinder 19. The diameter of the rotating mounting cylinder 19 is larger than the air-avoiding arc guide groove 162.

[0037] The cup cover 1 with a deceleration structure also includes a pop-up connector 20 and a pop-up ring 21. The pop-up ring 21 is sleeved on the cup cover body 11. The outer wall of the cup cover body 11 is provided with a cup cover boss. The upper end surface of the pop-up ring 21 is provided with multiple connecting columns 211. The number of pop-up connectors 20 is the same as the connecting columns 211. The lower end of the pop-up connector 20 is connected to the connecting column 211.

[0038] After the cup cover 1 with a deceleration structure is installed on the cup body 2, the pop-up ring 21 is placed on the installation step 201. Through the arrangement of the pop-up connector 20 and the pop-up ring 21, the clamping slider 13 can be retracted and disengaged from the groove 202. Under the action of the pop-up spring 22, the pop-up ring 21 pushes the installation step 201 downward, so that the cup cover 1 with a deceleration structure rises a certain distance.

[0039] The cup cover 1 with a deceleration structure also includes a sensing frame 23, which is fixedly mounted on one of the connecting posts 211, and can move up and down above the connecting mounting hole 112 along with the connecting post 211. An induction magnet 231 is provided on the sensing frame 23, and a Hall switch is provided on the controller component 12. The Hall switch can cooperate with the induction magnet 231 to obtain a lid closing signal.

[0040] Through the cooperation between the Hall switch and the induction magnet 231, when the user presses the cover to install, the pop-up ring 21 is squeezed upward, driving the induction magnet 231 on the induction frame 23 to move upward and close to the Hall switch. When pressed into place, the Hall switch senses the induction magnet 231, controls the drive part 14 to work, and realizes the automatic cover closing process in cooperation with the planetary gear assembly.
