ABSTRACT:
A portable fire extinguisher comprising a blower tube assembly that includes an outer tube with an inner mixing chamber disposed “upstream” from an adjacent outlet port that provides a passage to direct a discharge flow of mixed air and fire retardant out of the outer tube to extinguish a fire. The inner mixing chamber is adapted for communication with a portable reservoir containing a liquid fire retardant which is enabled to flow into the inner mixing chamber. The blower tube assembly further includes an inner tube that defines a blower tube inlet port adapted to receive the outlet port of a portable forced air blower. The inner tube is disposed for communication with the inner mixing chamber of the outer tube to enable a continuous volume of forced air to flow from a portable forced air blower, through the inner tube and into the inner mixing chamber of the outer tube. At least one ambient air intake port is provided for communication with the inner mixing chamber to enable ambient air to enter the inner mixing chamber and mix with a flow of forced air and fire retardant for discharge through the outlet port of the outer tube.
