It can be understood that when rainwater enters the second channel 15, the rainwater can drive the driving block 3141 to move. The driving block 3141 moves in the second channel 15. When the driving block 3141 moves to a certain position, the first liquid outlet 151 and the second liquid outlet 152 can be exposed.
