As shown in fig. 17 and 18, as an embodiment of this embodiment, the reinforcing structure is a reinforcing member fastened inside the sidewall of the water collecting chamber, and the outer diameter of the reinforcing member is slightly smaller than the inner diameter of the sidewall of the water collecting chamber;

or the reinforcing structure is a reinforcing piece fastened on the outer part of the side wall of the water collecting cavity, and the inner diameter of the reinforcing piece is slightly larger than the outer diameter of the side wall of the water collecting cavity.

As shown in fig. 17, the reinforcement member is a sheet-shaped reinforcement ring 1003 matched with the side wall of the water collection cavity, and the sheet-shaped reinforcement ring 1003 is fastened inside or outside the side wall 508 of the water collection cavity 503 through a clamping device 1100.

The clamping device 1100 described in this embodiment includes a clamping slot 1101, and the clamping device 1100 clamps the sheet-shaped reinforcing ring 1003 inside or outside the sidewall 508 of the water collecting cavity 503.

Further, the upper end opening of the sheet-shaped reinforcing ring 1003 according to the embodiment has a flanging structure 10031, so as to further enhance the overall strength of the sheet-shaped reinforcing ring 1003.

As shown in fig. 18, the reinforcing member is a steel wire-shaped reinforcing ring 1004 matched with the side wall of the water collecting cavity, the steel wire-shaped reinforcing ring 1004 is connected by a fastening nut 10041 to form a closed ring, the water collecting device 500 comprises an opening of the water collecting cavity, and the steel wire-shaped reinforcing ring 1004 is fastened inside or outside the side wall 508 of the water collecting cavity 503 and is arranged close to the opening of the water collecting cavity 503 by adjusting the fastening nut 10041.
