A double valve flusher includes a body, a separating plate, an upper and a lower valve base, a movable valve, a film valve, a fixing member, and an electromagnet. An upper leak room is formed between the film valve and the upper valve base. A leak room is formed between the separating plate, the lower valve base and the movable valve contained in a chamber in the body. The upper leak passageway in the upper leak room and the upper valve base is blocked or opened by the core of the electromagnet, thus controlling the film valve in disfiguring to block or open the leak passageway of the leak room and the lower valve base. Then the movable valve is controlled to move up and down to flush or stop flushing water into a urinal where this flusher is positioned.
