The water nozzle 16 is movably arranged in the first through hole 141, and the outer wall of the water nozzle 16 is sealingly fitted with the first through hole 141. The water nozzle 16 is provided with a blind hole 162 communicating with the lower end thereof and a side through hole 161 communicating with the blind hole. An accommodating portion 163 for accommodating the elastic member 15 is arranged outside. The elastic member 15 is arranged between the accommodating portion 163 and the water valve, and is used for providing the water nozzle 16 with an elastic force downward.

The water valve connector 21 is sleeved on the upper end of the water discharging pipe 23, and the middle part is provided with a second through hole 211 communicating with the water discharging pipe 23. When the water valve connector 21 is not connected with the water nozzle 16, the side through hole 161 only communicates with the blind hole 162. When the water valve connector 21 is connected with the water nozzle 16, the second through hole 211 is sealingly connected with the blind hole 162, and the water valve connector 21 pushes the elastic member 15 upward to move upward to the side through hole 161 and the cavity 121 is communicated, so that the water feeding pipe 11 and the water discharging pipe 23 are connected.

[0057] In the present application, the communication state of the water feeding pipe 11 and the water discharging pipe 23 is changed by the up-down sliding of the water nozzle 16. The water nozzle 16 can be arranged in the form of directly extending into the water feeding pipe 11, and correspondingly, the end of the water feeding pipe 11 is provided with a protruding portion for abutting against the elastic member 15.

At this time, the side through hole 161 only connects the blind hole 162 and does not connect the cavity 121, and the water in the upper water pipe 11 is sealed in the cavity.

[0060] Please refer to Figure 7 When the lower water assembly 2 is connected with the upper water assembly 1, the water valve connector 21 presses against the water nozzle 16 and moves the water nozzle 16 upward, and the water nozzle 16 moves upward along the first through hole 141 to the side through hole 161 and the cavity 121. When the lower water assembly 2 is connected with the upper water assembly 1, the side through hole 161 keeps connected with the cavity 121, and at this time, the water in the upper water pipe 11 can flow into the water nozzle 16 from the side through hole 161, and then flow into the second through hole 211 of the water valve connector 21, and finally flow into the lower water pipe 23.
