Improvements to a self-fluffing vehicle fire extinguisher where the improvements relate to a system where the extinguisher can be monitored and maintained. Further Improvements include an anti-bridging mechanism that is articulated from the exterior of the chamber to fluff, mix or stir the powder within the chamber to keep it in a liquefied state. An automatic fluffing motor and manual fluffing wheel. Pressurizing the fire extinguisher can be with an external gas chamber or can be with a compressor that maintains the pressure within the extinguisher. A delivery system can direct the fire extinguishing media to an area of the vehicle that has an elevated temperature or can distribute the media thorough the occupied or unoccupied portion of the vehicle.

A method of actuating an extinguisher system may comprise retaining a broadhead cutter in close proximity to a burst disc surface, receiving an impulse signal, actuating a spring release mechanism in response to receiving the impulse signal, driving a cutter shaft towards the burst disc surface in response to actuation, and piercing the burst disc surface via the broadhead cutter coupled to the cutter shaft.

The present disclosure relates to a broadhead cutter activation mechanism and system inside of a fire extinguisher. The broadhead cutter device may be attached to a cutter shaft which is driven downward when the elastic potential energy is released form a spring system. The broadhead cutter device may be configured to pierce and open a burst disc to release the flow of an extinguishing agent under pressure.

According to one aspect, a fire extinguisher includes a fire extinguisher reservoir and a fire extinguisher outlet burst disc that forms a discharge barrier between the fire extinguisher reservoir and a discharge head to retain a pressurized fire extinguishing agent at an internal fire extinguisher pressure within the fire extinguisher reservoir. A cutter is detained within the fire extinguisher proximate the fire extinguisher outlet burst disc. An interior container within the fire extinguisher reservoir has a container pressure and is sealed with a container burst disc. An activation device having a piercing member is operable to pierce the container burst disc and diffuse the container pressure to create a pressure differential relative to the internal fire extinguisher pressure at the cutter, thereby driving the cutter through the fire extinguisher outlet burst disc to release the pressurized fire extinguishing agent through the discharge head.
