Abstract
Improvements to a portable fire extinguisher are disclosed. The improvements allow for frequent and simplified maintenance of a fire extinguisher with minimal training and without need for custom equipment. The improvements include an anti-bridging mechanism that can be articulated from the exterior of the chamber to fluff, mix or stir the powder within the chamber to keep it in a liquefied state. These features will extend the service intervals while maintaining the fire extinguisher in a ready condition.
Claims20
A portable fire extinguisher including a chamber configured to be filled with fire suppressant material and to be pressurized with gas from a pressurized gas cartridge, the portable fire extinguisher further including a flow path for releasing the fire suppressant material from the chamber, the portable fire extinguisher comprising:
- an integral siphon tube having a first tube end coupled to the flow path and a second tube end disposed inside the chamber;
- a fluffing arm disposed in the chamber and configured to agitate the fire suppressant material in the chamber when the integral siphon tube is rotated, wherein the fluffing arm includes a first end coupled to the integral siphon tube and the fluffing arm extends radially away from the integral siphon tube to an opposite second end inside the chamber;
- and
- a support gusset coupled to the integral siphon tube and to the fluffing arm, wherein the support gusset extends radially away from the integral siphon tube inside of the chamber and supports at least a portion of the fluffing arm.
A method of maintaining fire suppressant material housed in a fire extinguisher, the method comprising:
- configuring the fire extinguisher providing to comprise a chamber filled with fire suppressant material, the chamber configured to be pressurized with gas from a pressurized gas cartridge, the portable fire extinguisher further configured with a flow path for releasing the fire suppressant material from the chamber, the portable fire extinguisher comprising an integral siphon tube having a first tube end coupled to the flow path and a second tube end disposed inside the chamber;
- agitating the fire suppressant material in the chamber using a fluffing arm disposed in the chamber and configured to agitate the fire suppressant material when the integral siphon tube is rotated, wherein the fluffing arm includes a first end coupled to the integral siphon tube and the fluffing arm extends radially away from the integral siphon tube to an opposite second end inside the chamber and comprising a support gusset coupled to the integral siphon tube and to the fluffing arm, wherein the support gusset extends radially away from the integral siphon tube inside of the chamber and supports at least a portion of the fluffing arm.

- an integral siphon tube having a first tube end coupled to the flow path and a second tube end disposed inside the chamber;
- a fluffing arm disposed in the chamber and configured to agitate the fire suppressant material in the chamber when the integral siphon tube is rotated, wherein the fluffing arm includes a first end coupled to the integral siphon tube and the fluffing arm extends radially away from the integral siphon tube to an opposite second end inside the chamber, the integral siphon tube includes an inlet at a first end of the integral siphon tube and an outlet at an opposite second end of the integral siphon tube, wherein the inlet is configured to receive the fire suppressant material from the chamber and the outlet is configured to provide the fire suppressant material to the flow path;
- and
- a support gusset coupled to the integral siphon tube and to the fluffing arm, wherein the support gusset extends radially away from the integral siphon tube inside of the chamber and supports at least a portion of the fluffing arm.
