The protrusion 156 is disposed at the other end of the first push rod 154, so as to drive the first push rod 154 to move toward the water outlet 123. One end of the first push rod 154 passes through the first fixing hole and is located in the water inlet and outlet pipe 120, and is connected with the blocking piece 150, so as to drive the blocking piece 150 to move along the water inlet and outlet pipe 120 towards the direction far away from the water outlet 123, i.e. towards the third water gap 122, so as to open the water outlet 123 and block the third water gap 122, thereby realizing water drainage.

When water is supplied to the water mist module 300, the motor 161 rotates reversely to drive the gear 162 to rotate reversely, so as to drive the transmission member 163 to rotate reversely. The guiding slope 164 moves relative to the protrusion 156 in a reverse direction, a space is formed between the protrusion 156 and the guiding slope 164, the first elastic member 155 is supported between the protrusion 156 and the first fixing member 153, and the first elastic member 155 is reset to drive the protrusion 156 to move in a reverse direction, so that the first ejector 154 moves in a reverse direction, the blocking member 150 is pressed at the water outlet 123, the water outlet 123 is blocked, the third water outlet 122 is opened, and water is supplied to the water mist assembly 300. Optionally, during the reverse movement of the guiding inclined surface 164, the protrusion 156 is always abutted against the guiding inclined surface 164 due to the supporting force of the first elastic member 155, preventing the protrusion 156 from being separated from the guiding inclined surface 164, and improving the working stability of the water supply assembly 100.

Optionally, the first elastic member 155 includes a spring, the cross-sectional area of the protrusion 156 is larger than that of the first supporting rod 154, and the first elastic member 155 is disposed outside the first supporting rod 154.

As shown in fig. 2, 3 and 6, in some alternative embodiments, the block piece 150 includes a first sub-block piece 151 and a second sub-block piece 152, the first sub-block piece 151 corresponding to the drain opening 123, the first sub-block piece 151 for opening or closing the drain opening 123.

With this alternative embodiment, the second sub-blocking member 152 is disposed along the inner wall surface of the water inlet and outlet pipe 120, and the second sub-blocking member 152 can move relative to the inner wall surface of the water inlet and outlet pipe 120, so that when the third water gap 122 is blocked, the flow of the sewage in the water inlet and outlet pipe 120 is not affected, and the normal operation of the water supply assembly 100 is ensured.

In some alternative embodiments, the diameter of the first sub-block piece 151 gradually decreases along the direction from the water inlet and outlet pipe 120 to the water outlet 123, and the first sub-block piece 151 is funnel-shaped.

In this embodiment, the water inlet/outlet pipe 120 faces the water outlet 123, and is along the flow direction of the sewage when the water is discharged from the water inlet/outlet pipe 120. The first sub stopper 151 is for closing the water discharge opening 123, and when the first sub stopper 151 closes the water discharge opening 123, the first sub stopper 151 moves toward the water discharge opening 123. The diameter of the first sub-sealing member 151 gradually decreases along the direction from the water inlet/outlet pipe 120 to the water outlet 123, so that the water outlet 123 is gradually sealed in the process that the first sub-sealing member 151 moves towards the water outlet 123, and the closer the first sub-sealing member 151 is attached to the side wall of the water outlet 123, the better the sealing effect is.

As shown in fig. 2 and 3. In some optional embodiments, the water supply assembly 100 further includes a limiting member 170, one side of the limiting member 170 is connected to an inner wall surface of the water inlet and outlet pipe 120, the second sub-blocking member 152 is located between the inner wall surface of the water inlet and outlet pipe 120 and the limiting member 170, and the limiting member 170 is used for pressing the second sub-blocking member 152 to the third water gap 122.

When the second sub-blocking member 152 blocks the third water port 122, the third water port 122 is communicated with the water supply port 112, and when water is stored in the water supply assembly 100, the water source applies pressure to the second sub-blocking member 152, so that the second sub-blocking member 152 is separated from the third water port 122, and water leakage at the third water port 122 is caused. In this embodiment, the limiting member 170 is disposed in the water inlet/outlet pipe 120, the second sub-blocking member 152 is located between the inner wall surface of the water inlet/outlet pipe 120 and the limiting member 170, when the water source in the water supply assembly 100 applies pressure to the second sub-blocking member 152, the limiting member 170 can limit the second sub-blocking member 152, and the second sub-blocking member 152 is pressed at the third water gap 122, so as to seal the third water gap 122.
