The driven rotating rod contacts the squeezing sheet through a spring, and a drainage port connected to the outside is opened on the side of the sponge layer corresponding to the front of the fixed shell. When the driven rotating rod moves inside the fixed shell, the squeezing sheet can apply pressure to the sponge layer, so that the moisture absorbed by the mist wiped inside the sponge layer is continuously squeezed out, and the squeezed moisture can be discharged outward from the drainage port, thereby ensuring the sponge layer's effect of cleaning the mist. The squeezing sheet is circular, a triangular convex ridge is provided on the front of the squeezing sheet, and a plurality of triangular convex ridges are equidistantly provided along the circumference of the squeezing sheet.
