The intermittent pressurized fluid spray device includes water storage reservoir, air reservoir and multipath valves connected with the air reservoir and water storage reservoir. Said multipath valveincludes a main valve and a leading valve, in which the main valve is placed between the air reservoir and water storage reservoir, and the leading valve possess two positions respectively connected with pressurized air and atmosphere. By controlling two positions of the leading valve it can control opening and closing of valve core of main valve to make the air reservoir filled with pressurized air and water storage reservoir filled with water communicate or shut off. It possesses the advantages of small volume, simple structure, convenient operation and reliable performance, etc..
