In an embodiment, the liquid inlet pipe 300 includes a pipe body 310 and a connecting cover 320, the connecting cover 320 is disposed around the pipe body 310, and an accommodating cavity 321 is formed by enclosing the pipe body 310 and the connecting cover 320 at intervals, an opening of the accommodating cavity 321 is located at one end of the pipe body 310 facing the sealing member 220, the pipe body 310 is used for driving the sealing member 220 to deform and open the connecting pipe 210, and when the sealing member 220 is opened, the sealing member 220 is accommodated in the accommodating cavity 321.
In this embodiment, the length of the tube body 310 is smaller than that of the connection cover 320, i.e. the end of the tube body 310 is located at the inner side of the connection cover 320, so that when the liquid inlet tube 300 contacts with the seal assembly 200, firstly the connection cover 320 contacts with the moving structure 230 and drives the moving structure 230 to move, and as the liquid inlet tube 300 moves, the moving structure 230 is separated from the seal member 220, at this time, the seal member 220 is in a movable state, after the tube body 310 contacts with the seal member 220 at this time, the seal member 220 can be smoothly pushed outwards, and at the same time, as the connection cover 320 covers the outer side of the tube body 310, once the tube body 310 splashes with waste water, the connection cover 320 can also block the waste water splashed from the tube body 310, thereby further improving the splash preventing effect of the seal assembly 200.
In addition, by arranging the accommodating cavity 321 inside the connecting cover 320, when the pipe body 310 drives the sealing element 220 to deform outwards, the accommodating cavity 321 can accommodate the sealing element 220 so as to have a compact structure between the pipe body and the accommodating cavity, and meanwhile, the inner wall of the accommodating cavity 321 can limit the movement of the sealing element 220 so as to prevent the deformation of the sealing element 220 from exceeding the material bearing limit of the sealing element, thereby improving the durability of the sealing assembly 200; after the sealing member 220 is accommodated in the accommodating cavity 321, the sealing member 220 can also deform to a certain extent and fix the liquid inlet pipe 300 and the sealing assembly 200 due to the flexibility of the sealing member 220, so as to improve the connection firmness between the liquid inlet pipe 300 and the sealing assembly 200.
