Abstract

A valve structure with an elastic anti-leakage member includes a spool, a seat, and a switch. The spool body has at least one inner notch formed on a side of the spool body, and the inner notch has at least one elastic anti-leakage member installed in the inner notch, and the seat has an inner chamber with an internal cavity wall. The spool is contained in an inner of the seat, and the elastic anti-leakage member installed in the inner chamber of the inner notch of the spool body has a surface elastically abutting against the internal cavity wall of the inner chamber of the seat to achieve a good water anti-leakage effect.
