When the upper cover 311 rotates relative to the lower cover 312, the shaft rod 320 also rotates synchronously, thereby driving the turntable 330 to rotate.

[0038] The fixing nut 322 is sleeved on the screw rod 321 and is threadedly connected to the screw rod 321. The fixing nut 322 can move up and down along the screw rod 321. When it is necessary to install the driving assembly 300 on the washbasin, the distance between the fixing nut 322 and the top surface of the housing 340 can be adjusted by rotating the fixing nut 322, and the driving assembly 300 is locked on the washbasin. It should be noted that a through hole for installing the driving assembly 300 is opened on the washbasin. The diameter of the through hole is equivalent to the diameter of the screw rod 321, and the through hole is located on the upper surface of the washbasin and not in the washbasin of the washbasin.

[0039] A gear member 331 facing the inner wall of the housing 340 is provided on the turntable 330, and a plurality of gear grooves 341 facing the turntable 330 are opened on the inner wall of the housing 340. Among them, during the rotation of the knob 310, the turntable 330 rotates synchronously, and the gear member 331 can abut against or disengage from the gear groove 341 to lock or unlock the turntable 330. With the cooperation of the gear member 331 and the plurality of gear grooves 341, a plurality of positioning gears are formed to control the opening size between the drain cover 200 and the top end of the drain passage 111.

[0040] The gear member 331 includes a ball 332 and an elastic member 333. The ball 332 can be a steel ball, and the elastic member 333 can be a spring. A groove for accommodating the ball 332 and the elastic member 333 is opened on the turntable 330. The axis of the groove is perpendicular to the inner wall of the housing 340. One end of the elastic member 333 is connected to the bottom wall of the groove, and the other end is connected to the elastic member 333. Under the action of the elastic member 333, the ball 332 can perform telescopic movement in a direction perpendicular to the inner wall of the housing 340. Among them, the housing 340 can be made of a metal material. When the elastic member 333 rotates relative to the gear groove 341, the ball 332 colliding with the inner wall of the housing 340 can make a sound.

[0041] A connecting pipe 352 is connected between the housing 340 and the main body 100, and a steel wire rope 350 is provided in the connecting pipe 352. Among them, spherical parts 351 can be provided at both ends of the steel wire rope 350. The spherical parts 351 can be steel balls. The two ends of the steel wire rope 350 are respectively connected to the pushing member 360 and the turntable 330. The turntable 330 can drive the steel wire rope 350 to move to drive the pushing member 360 to swing.

[0042] Among them, when the knob 310 rotates clockwise, the turntable 330 also rotates clockwise synchronously, and the steel wire rope 350 is pulled back into the housing 340 by the turntable 330. Correspondingly, the steel wire rope 350 in the main body 100 is dragged back into the connecting pipe 352. When the knob 310 rotates counterclockwise, the turntable 330 also rotates counterclockwise synchronously, and the steel wire rope 350 is pushed into the connecting pipe 352 by the turntable 330. Correspondingly, the steel wire rope 350 in the main body 100 is pushed out of the connecting pipe 352 and extends into the main body 100.

[0043] The driving member 360 is installed in the main body 100 in a swinging manner. On the side of the driving member 360 facing the spherical portion 351, there is a groove 362 sleeved on the outer side of the spherical portion 351. The groove 362 can cooperate with the spherical portion 351, so that when the steel wire rope 350 extends into the main body 100 or retracts from the main body 100 into the connecting pipe 352, the driving member 360 can swing relative to the spherical portion 351 on the steel wire rope 350.

[0044] Reference Figures 1 to 4 The main body 100 is provided with a water drainage channel 111, and a water drainage cover 200 is covered at the top opening of the water drainage channel 111.

[0045] At the bottom of the water drainage cover 200, there is a connecting rod 210 extending downward, and the connecting rod 210 abuts against the driving member 360. During the rotation of the turntable 330, the steel wire rope 350 can drive the driving member 360 to swing so as to lift the connecting rod 210. Among them, a connecting cap 220 is arranged at the bottom of the connecting rod 210, and an arc surface is arranged at the bottom end of the connecting cap 220. A guiding surface 361 is arranged on the side of the driving member 360 facing the connecting rod 210, and the guiding surface 361 can cooperate with the arc surface. When the driving member 360 swings, the arc surface and the guiding surface 361 can be better connected, and the friction force between the two is small, so that the driving member 360 can easily lift the connecting rod 210.

[0046] As Figure 3 shown, the water drainage cover 200 is in a closed state. During the clockwise rotation of the knob 310, the steel wire rope 350 in the main body 100 is pulled back into the connecting pipe 352, so that the driving member 360 swings downward along the spherical portion 351 on the steel wire rope 350, and then the connecting rod 210 moves vertically downward, driving the water drainage cover 200 to move downward until the water drainage cover 200 is in a closed state.

[0047] As Figure 4 shown, the water drainage cover 200 is in an open state. During the counterclockwise rotation of the knob 310, the steel wire rope 350 in the connecting pipe 352 extends into the main body 100, so that the driving member 360 swings upward along the spherical portion 351 on the steel wire rope 350, and then the connecting rod 210 moves vertically upward, driving the water drainage cover 200 to move upward to realize the open state of the water drainage cover 200. In addition, by rotating the knob 310 by a certain angle, the gear member 331 on the turntable 330 can be clamped in a certain gear slot 341 to control the opening size between the water drainage cover 200 and the top of the water drainage channel 111.
