  • Patent number: 9206914
    Abstract: A check valve is provided. The check valve includes a position limiting member, a back-flow preventing member and a lid body. The back-flow preventing member is disposed between the position limiting member and the lid body, and a blocking portion of the back-flow preventing member is flexible. When the blocking portion is impacted by an external water source, a gap will be formed between an external peripheral verge of the blocking portion and a stepped portion of the position limiting member to allow the water source to flow through the position limiting member. When the blocking portion is impacted by a reverse water source, the external peripheral verge of the blocking portion is abutted against the stepped portion to unallow the water source to flow through the position limiting member.
