A multipurpose spray device is provided to put out a fire by automatically spraying fire extinguishing materials by sensing a fire with a sensor installed at a sprinkler and to use the compressed air as the jet-propelling material by filling a material storing container with agricultural water, agricultural chemicals, fertilizers, paints, or washing water and the compressed air. In a multipurpose spray device, a compressed air storing container(2) and a material storing container(3) are installed in parallel on a device rack(1) having a handle(1a) and wheels(1b). An injection port(21) equipped with an opening and closing valve(21a), a pressure gauge(22), and a discharge port(23) equipped with an opening and closing valve(23a) are installed at an injection pipe(20) formed at the upper end of the compressed air storing container. An injection port(30a) having an opening and closing valve(30b) is installed at an injection pipe formed at the upper end of the material storing container. An injection pipe(31) equipped with an opening and closing valve(31a) is connected to the side of the injection port and connected to the discharge port of the compressed air storing container. A receiving chamber is formed at the inner end of the injection pipe. A stirrer has plural curved pipes arranged on the peripheral wall at regular intervals. A liquid quantity indication pipe(33) is installed on the peripheral wall. An air exhaust port(35) having an opening and closing valve is mounted on the side of the injection port. A jetting pipe(4) is protruded at a lower outlet of the material storing container. A stirring unit having plural curved pipes attached to the peripheral wall is formed at an inlet of the jetting pipe. The outer end of the jetting pipe is connected to a discharge pipe(40) attached with an opening and closing valve(40a). Heat sensing sprinklers(41) are disposed at the upper and lower sides of the discharge pipe. A jetting pipe(42) is installed at one side of the jetting pipe and an opening and closing valve(42a) is attached on the jetting pipe. A compressed air inflow pipe(34) is installed by boring a hole through the peripheral wall of the material storing container. A stirrer has curved pipes attached to an annular forming unit formed at the inner end at regular intervals. An inlet of an inflow pipe communicates with the discharge port of the discharge port of the compressed air storing container.
