When the drain 1000 is in the drain state, the overflow tube 260 is in a second position, such as the position shown in fig. 3, where the arrows in fig. 3 indicate the direction of water flow. At this time, the sealing ring 300 is separated from the annular protrusion 111, and the water inlet 101, the inner cavity of the main housing 110 and the water outlet 102 are sequentially communicated. When the basin 2000 needs to drain, the overflow pipe 260 is driven by the motor 510 to move to the second position, and at this time, the water in the basin 2000 passes through the water inlet 101, the inner cavity of the main housing 110 and the water outlet 102 in sequence, and finally is discharged out of the drainage device 1000.

And the drainage device 1000 has both drainage and overflow functions, so that the counter basin 2000 only needs to be provided with one drainage hole without being provided with an overflow hole.

It should be noted that, in another embodiment of the present invention, the main housing 110 may not be provided with the annular protrusion 111, but the inner diameter of the lower end of the main housing 110 may be gradually reduced to enable the sealing ring 300 to abut against the inner wall of the main housing 110 so as to seal and isolate the water storage cavity 112 from the water outlet 102, instead, the sealing ring 300 may be provided with the annular protrusion 111. Alternatively, the lower end of the overflow pipe 260 extends outward to form a flange (not shown), the sealing ring 300 abuts against the inner wall of the main housing 110, and the flange can support the sealing ring 300, so as to prevent the sealing ring 300 from being deformed too much under the pressure of water, which may result in water leakage. Specifically, an appropriate scheme is selected according to actual conditions, and the embodiment of the present invention is described by taking the case where the main housing 110 is provided with the annular protrusion 111 as an example.

Referring to fig. 4 and 5, in an embodiment of the present invention, the driving part 500 includes a control module (not shown) and a sensor 520, the sensor 520 is used for acquiring a user control signal, and the control module is electrically connected to the motor 510 and the sensor 520 respectively. Wherein, the control module can control the motor 510 to rotate according to the user control signal obtained by the sensor 520. The user control signal may be a gesture signal, the gesture signal being generated by a user waving his hand.

Specifically, the sensor 520 includes infrared pair tubes (not shown), the infrared pair tubes continuously emit infrared signals outwards, when the user's hand sweeps a position about 20-30 mm above the sensor 520, the infrared signals pass through the operational amplifier circuit and the shaping circuit, and output high level signals to the control module, the control module receives the abrupt level signals, and after internal signal processing, outputs positive logic signals to the motor 510, and controls the motor 510 to open the drainage device 1000, i.e., to separate the sealing ring 300 from the annular protrusion 111. If no new user control signal is detected within 30 minutes, an interrupt signal is triggered to the control module through the built-in timer, a negative logic signal is sent to the motor 510, and the motor 510 is controlled to close the drainage device 1000, that is, the sealing ring 300 and the annular convex part 111 are in sealing fit. If the user control signal is detected again within 30 minutes, the alternating infrared signal passes through the operational amplifier circuit and the shaping circuit, a low level is output to the control module, the control module receives the abrupt level signal, the control module outputs a negative logic signal to the motor 510 after internal signal processing, and controls the motor 510 to close the drainage device 1000, namely, the sealing ring 300 is in sealing fit with the annular convex part 111. When a bounce driving mode is adopted in the related technology, a user needs to stretch hands to the bottom of the basin and control a bounce switch, dirty water needs to be contacted in the process, and user experience is poor. The drainage device 1000 of the application adopts a gesture control mode, a user does not need to contact the drainage device 1000, the state of the drainage device 1000 can be switched easily, dirty water does not need to be contacted, and user experience is good.

In another embodiment of the present invention, the user control signal can also be a voice control signal. For example, the driving part 500 further includes a WiFi module, a control module, and a voice receiving module, the voice receiving module is used for receiving voice information of a user and sending the voice information to the control module, the WiFi module enables the water discharge apparatus 1000 to have a networking function, so that the control module can analyze the voice information and control the motor 510 to rotate according to a corresponding analysis result.

When the motor 510 fails, the state of the drainage device 1000 cannot be switched, and in order to solve the problem, as shown in fig. 4 and 5, in an embodiment of the present invention, the driving part 500 further includes a knob 530 and an elastic member, and the elastic member may be a spring 534, rubber with elasticity, or the like. The knob 530 is provided at an inner side thereof with a coupling seat 531, and an inner portion of the coupling seat 531 defines a coupling chamber 532, and the coupling chamber 532 has a substantially "convex" shape in cross section. The transmission shaft 400 is inserted into the rotor of the motor 510, so that the upper end of the transmission shaft 400 protrudes out of the motor 510. One end of the spring 534 is inserted into the connection chamber 532, and the other end of the spring 534 is inserted into the upper end of the transmission shaft 400. Knob 530 has a first state and a second state, and when knob 530 is in the first state, such as shown in fig. 3, spring 534 separates connecting base 531 from drive shaft 400, preventing motor 510 from driving drive shaft 400 to rotate knob 530 together. When the knob 530 is in the second state, for example, as shown in fig. 4, the user presses the knob 530 to the position where the connection seat 531 is sleeved on the transmission shaft 400 by overcoming the elastic force of the spring 534, so that the knob 530 can drive the transmission shaft 400 to rotate, and the transmission shaft 400 can drive the overflow pipe 260 to ascend or descend, so as to switch the state of the drainage device 1000. It can be understood that, with the scheme of the motor 510 and the knob 530, when the motor 510 fails, the knob 530 can also drive the transmission shaft 400 to rotate, which facilitates the switching between the drainage state and the water storage state of the drainage device 1000, and improves the reliability of the drainage device 1000.

In another embodiment of the present invention, in order to separate the knob 530 from the transmission shaft 400, a plurality of supporting platforms (not shown) may be disposed on the inner wall of the mounting base 150, the plurality of supporting platforms are disposed around the inner wall of the mounting base 150 at intervals, and a plurality of ribs (not shown) are disposed on the outer wall of the knob 530 at intervals. When the knob 530 is in the first state, the plurality of ribs can abut against the plurality of support tables to separate the connection seat 531 from the transmission shaft 400; when the knob 530 is in the second state, the rib can be lowered to a position where the connecting seat 531 and the transmission shaft 400 are connected through a gap between the adjacent supporting platforms, so that the knob 530 can drive the transmission shaft 400 to rotate.

It should be noted that, in another embodiment of the present invention, the knob 530 may be directly and fixedly connected to the transmission shaft 400, and the knob 530 can directly drive the transmission shaft 400 to rotate, so as to switch the operating state of the drainage device 1000 when the motor 510 fails.

It should be noted that, in another embodiment of the present invention, the motor 510 is a dual-output motor (not shown in the drawings), two ends of the dual-output motor are respectively provided with a first output shaft and a second output shaft, the first output shaft is connected to the transmission shaft 400, the knob 530 has a first state and a second state, and when the knob 530 is in the first state, the connecting seat 531 of the knob 530 is separated from the second output shaft; when the knob 530 is in the second state, the connecting seat 531 of the knob 530 is drivingly connected to the second output shaft. It can be understood that the first output shaft and the second output shaft can be integrally formed rotating shafts, and two ends of each rotating shaft respectively extend out of two ends of the double-output motor; alternatively, the first output shaft and the second output shaft may be two independent rotating shafts, and the two shafts are connected through a coupling or other structures.
