At the same time, the second spring 2220 is deformed by force. When the cam 2106 continues to rotate, the deformation of the second spring 2220 drives the extrusion plate 2219 to reset, thereby achieving the effect of driving the moving rod 2218 to move, so that the piston 2208 moves up and down in the water collecting pipe 2207. When the piston 2208 moves downward, the salt in the water collecting pipe 2207 is Water is squeezed into the second one-way valve 2209 and the second water pipe 2210, so that the brine enters the first arc tube 2211 and the second arc tube 2212 and is sprayed out through the spray tube 2213, thereby achieving the effect of melting the snow on the ground. When the piston 2208 moves upward, the brine in the water tank 2201 will enter the third bellows 2203, enter the inner cavity of the connecting pipe 2202 through the third bellows 2203, and then enter the first bellows 2204 and the first water pipe 2205 through the connecting pipe 2202, and enter the inner cavity of the water collecting pipe 2207 through the first one-way valve 2206, thereby achieving the effect of replenishing the brine in the water collecting pipe 2207.
