Wherein, the driving mechanism can adopt a manual driving structure or an automatic driving structure to drive the water stopping mechanism 3 to move upwards.

In this embodiment, the water stopping device further comprises a lifting mechanism 6, the lifting mechanism 6 is connected with the water stopping mechanism 3, and the automatic driving structure drives the lifting mechanism 6 to move so as to lift the water stopping mechanism 3.

In this embodiment, the water stopping mechanism 3 includes a water stopping unit 32 for closing the drainage channel 11 and a fixing seat 31 connected with the lifting mechanism 6, a guide hole for the fixing seat 31 to move up and down is formed in the valve body 2, and the fixing seat 31 moves up and down along the guide hole under the action of the driving mechanism and the reset mechanism 5, so as to prevent the water stopping mechanism 3 from closing the drainage channel 11 inaccurately in the water tank due to the buoyancy of water.

In this embodiment, the reset mechanism 5 is a reset spring, one end of the spring is fixed on the valve body 2, the other end of the spring abuts against the water stopping mechanism 3 to enable the water stopping mechanism 3 to close the drainage channel 11, when the driving mechanism drives the water stopping mechanism 3 to ascend, the water stopping mechanism 3 will extrude the spring to enable the spring to have elastic force, and when the driving mechanism does not apply driving force to the water stopping mechanism 3 any more, under the action of the elastic force of the spring, the water stopping mechanism 3 can automatically reset, so as to close the drainage channel 11.

Referring to fig. 3 and 4, the driving mechanism adopts an automatic driving structure, and includes a sensing device and a water pump 41, the sensing device and the water pump 41 are electrically connected, when the sensing device senses that a user is close to or far away from the driving mechanism, a signal is transmitted to start the water pump 41, the water pump 41 pressurizes and pushes the lifting mechanism 6 to ascend to drive the water stopping mechanism 3 to ascend, and then the water discharging channel 11 is opened to discharge water. Of course, the water pump 41 may not be always turned on, and a time value may be set, for example, five seconds after the water pump 41 is turned on, the power supply may be automatically turned off after the water pump 41 works for five seconds, the water pump 41 starts to release the pressure, and the water stopping mechanism 3 descends under the action of the resetting mechanism 5 to close the water discharging passage 11.

The valve body 2 is internally provided with an accommodating cavity 23 and a sliding cavity 24, the water pump 41 is arranged in the accommodating cavity 23, and the lifting mechanism 6 is arranged in the sliding cavity 24. The water pump 41 has a water inlet 411 and a water outlet 412, and when the water pump 41 is started, water can be sucked into the water pump 41 from the water inlet 411 and then discharged from the water outlet 412 under the action of pressure difference. In this embodiment, a connection hole 241 communicating with the accommodating chamber 23 is disposed on a side wall of a lower end of the sliding chamber 24, the water pump 41 is installed in the accommodating chamber 23, and the water outlet 412 enters the sliding chamber 24 from the connection hole 241. A support portion 242 is provided in the slide chamber 24, and preferably, the support portion 242 has a ring shape. The lifting mechanism 6 is annular, the radius of the lifting mechanism 6 is matched with that of the supporting portion 242, a lifting portion 611 extends outwards from the upper end of the lifting mechanism 6, and when the lifting mechanism 6 is placed on the supporting portion 242, the lifting portion 611 can abut against the inner wall of the sliding cavity 24. The height of the supporting part 242 in the sliding cavity 24 is higher than that of the connecting hole 241, the lifting part 611, the supporting part 242 and the inner wall of the sliding cavity 24 form a lifting space 243, when the water pump 41 is started, water enters the lifting space 243 from the water outlet 412 of the water pump 41, only the lifting mechanism 6 can move, the lifting part 611 can be lifted slowly under the action of pressure, the fixing seat 31 is provided with the top of the lifting mechanism 6, the fixing seat 31 can be driven to move upwards when the lifting mechanism 6 rises, the water stopping unit 32 is lifted, and the drainage channel 11 is opened to discharge the water in the water tank to flush the toilet. It should be noted that the lifting space 243 should be a sealed space, so that when the water pump 41 is turned on, the pressure in the lifting space 243 is increased to push the lifting mechanism 6, and therefore, the sealing members 7 are disposed at the upper and lower ends of the lifting mechanism 6, the sealing members 7 are engaged with the inner wall of the sliding cavity 24 and the side wall of the supporting portion 242 to seal the lifting space 243, and when water enters the lifting space 243, the pressure difference between the lifting space 243 and other parts of the sliding cavity 24 is increased, so as to lift the lifting mechanism 6.

Further, in order to prevent the lifting mechanism 6 from moving upwards all the time, a plurality of pressure relief valves are arranged at the top of the lifting mechanism 6, and when the pressure in the lifting space 243 reaches a certain value, the pressure relief valves can be opened automatically to relieve the pressure, so that the pressure in the lifting space 243 is ensured, and the lifting mechanism 6 does not rise any more. Preferably, three pressure release valves are uniformly distributed at the top of the lifting mechanism 6.

Referring to fig. 5, the driving mechanism adopts a manual driving structure, and comprises a manual control box 42 and a lifting rope 43, the valve body 2 is provided with a connecting seat 25, the manual control box 42 is connected with the connecting seat 25 through a connecting sleeve 421, so that the manual control box 42 can be arranged outside the water tank, and manual control is facilitated. The lifting rope 43 enters the valve body 2 along the connecting sleeve 421 to be connected with the fixing seat 31, when pressure is applied to the manual control box 42, the manual control box 42 controls the lifting rope 43 to ascend to drive the fixing seat 31 to ascend, so that the water stopping unit 32 is driven to ascend to open the drainage channel 11, and when pressure is not applied to the manual control box 42, the water stopping mechanism 3 descends under the action of the resetting mechanism 5. It should be noted that, the lifting mechanism 6 is located at the lower end of the fixing seat 31 and is not connected to the fixing seat 31, so that when the lifting rope 43 drives the fixing seat 31 to rise, the lifting mechanism 6 does not rise together with the fixing seat 31, the friction resistance of the lifting mechanism during flushing by the manual driving structure is reduced, and the problem that the lifting mechanism 6 is stuck and does not reset due to the work of the lifting mechanism 6 during flushing by the manual driving structure is also reduced.
