A lightweight fire extinguisher is disclosed. In one embodiment, the fire extinguisher, which is portable, includes a press-source fluid container capable of retaining compressed air; extinguishant containers capable of retaining extinguishant; a pressure-source fluid tube connected to the pressure-source fluid container and the extinguishant containers, for leading the compressed air retained in the pressure-source container to the extinguishant containers; a pressure reducing valve intervening in the pressure-source fluid tube, for reducing pressure of the compressed air flowing down the pressure-source fluid tube; discharge device capable of discharging the extinguishant retained in the extinguishant containers; and an extinguishant tube connected to the extinguishant containers and the discharge device, for leading the extinguishant retained in the extinguishant containers to the discharge device.

A fire extinguisher comprising: a pressure-source fluid container to retain compressed pressure-source fluid;an extinguishant container to retain extinguishant;a pressure-source fluid tube connected to the pressure-source fluid container and the extinguishant container, to lead the pressure-source fluid retained in the pressure-source container to the extinguishant container;a pressure reducing device intervening in the pressure-source fluid tube, to reduce pressure of pressure-source fluid flowing down the pressure-source fluid tube;a discharge device to discharge the extinguishant retained in the extinguishant container;an extinguishant tube connected to the extinguishant container and the discharge device, to lead the extinguishant retained in the extinguishant container to the discharge device;a down flow prevention device, intervening in the extinguishant tube, to prevent the pressure-source fluid from flowing down the extinguishant tube; anda gas supply tube connected to the pressure reducing device and a breathing apparatus. 2. The fire extinguisher of claim 1, wherein the pressure reducing device is a pressure control valve to reduce the pressure of the pressure-source fluid and maintaining the pressure constant. 3. The fire extinguisher of claim 2, wherein the pressure-source fluid retained in the pressure-source fluid container is a mixture gas containing at least O2. 4. The fire extinguisher of claim 2, further comprising an excessive flow prevention device which intervenes in the pressure-source fluid tube and prevents the pressure-source fluid from flowing down the pressure-source fluid tube when a flow volume of the pressure-source fluid flowing down the pressure-source tube reaches a predetermined flow volume or more. 5. The fire extinguisher of claim 2, wherein the extinguishant is a flame retardant aqueous solution having a resin dissolved, which resin becomes higher in viscosity as a temperature rises. 6. The fire extinguisher of claim 2, further comprising a frame for arranging the pressure-source fluid container and the extinguishant container, wherein the frame is configured to hold the pressure-source fluid container and the extinguishant container upright. 7. The fire extinguisher of claim 1, wherein the pressure-source fluid retained in the pressure-source fluid container is a mixture gas containing at least O2. 8. The fire extinguisher of claim 7, wherein a back flow prevention device which intervenes in the pressure-source fluid tube and prevents the extinguishant from flowing back in the pressure-source fluid tube from the extinguishant container toward the pressure-source container, is provided downstream of the pressure reducing device in a direction that the pressure-source fluid flows down. 9. The fire extinguisher of claim 8, further comprising an excessive flow prevention device which intervenes in the pressure-source fluid tube and prevents the pressure-source fluid from flowing down the pressure-source fluid tube when a flow volume of the pressure-source fluid flowing down the pressure-source tube reaches a predetermined flow volume or more. 10. The fire extinguisher of claim 8, wherein the extinguishant is a flame retardant aqueous solution having a resin dissolved, which resin becomes higher in viscosity as a temperature rises. 11. The fire extinguisher of claim 7, further comprising an excessive flow prevention device which intervenes in the pressure-source fluid tube and prevents the pressure-source fluid from flowing down the pressure-source fluid tube when a flow volume of the pressure-source fluid flowing down the pressure-source tube reaches a predetermined flow volume or more. 12. The fire extinguisher of claim 7, wherein the extinguishant is a flame retardant aqueous solution having a resin dissolved, which resin becomes higher in viscosity as a temperature rises. 13. The fire extinguisher of claim 1, further comprising excessive flow prevention device which intervenes in the pressure-source fluid tube and prevents the pressure-source fluid from flowing down the pressure-source fluid tube when a flow volume of the pressure-source fluid flowing down the pressure-source tube reaches a predetermined flow volume or more. 14. The fire extinguisher of claim 1, wherein the extinguishant is a flame retardant aqueous solution having a resin dissolved, which resin becomes higher in viscosity as a temperature rises. 15. The fire extinguisher of claim 1, further comprising a frame to arrange the pressure-source fluid container and the extinguishant container, wherein the frame is configured to hold the pressure-source fluid container and the extinguishant container upright. 16. The fire extinguisher of claim 1, wherein the extinguishant is a flame retardant aqueous solution having a resin dissolved, which resin becomes higher in viscosity as a temperature rises. 17. The fire extinguisher of claim 1, wherein the down flow prevention device is arranged in the extinguishment container. 18. The fire extinguisher of claim 1, wherein the down flow prevention device is configured to prevent pressure-source fluid transferred to the extinguishant container from the pressure-source fluid container from flowing down the extinguishant tube.
