A slide rod having a sealing plate provided at an upper end vertically and slidably engages with a middle portion in the gutter spout cage by means of a vertical sliding engagement support frame, and serves as a spool capable of reciprocating vertically. An upper magnet and a lower magnet having the same polarity at opposite ends, and where vertical repulsion occurs, are respectively provided in a position at a lower end of the slide rod and in a corresponding position at the bottom of the gutter spout cage, and are used to provide an upward reset magnetic repulsion force to the slide rod and the sealing plate. A ring-shaped flange is provided at an upper portion of the gutter spout cage, and the ring-shaped flange and the sealing plate press against each other vertically to achieve sealing. When driven by pushing force resulting from flushing and draining, the sealing plate moves downwards, such that an opening to the drainage channel is formed between the sealing plate and the ring-shaped flange. An initial state is resumed after completion of the flushing and draining. The invention has good sealing performance, is reliable, facilitates water conservation and maintenance, and has a long service life.
