Further, the outer wall surface of the fixed portion 311 is provided with an annular groove 3112. The water level detection assembly 30 includes the first sealing member 34 arranged in the annular groove 3112. The first sealing member 34 abuts against the fixed portion 311 and the connecting wall 122, respectively. The annular groove 3112 arranged on the fixed portion 311 allows the first sealing member 34 to be installed on the fixed portion 311 in advance. During assembly, the fixed portion 311 and the connecting wall 122 are directly inserted, without the need for manual support of the first sealing member 34 for assembly, thereby reducing the assembly difficulty. In other embodiments, the annular groove 3112 can also be arranged on the inner wall of the connecting wall 122, and the first sealing member 34 is installed in the annular groove 3112 in advance.

[0041] In some embodiments, referring to Figure 6 The water level detection assembly 30 includes a second sealing member (not shown in the figure).
