Abstract

A fire extinguisher assembly is disclosed, providing a connection from a standard fire extinguisher tank through to a housing with dispersion vents. A spray nozzle is secured within the housing for dispersing the fire retardant agent through the dispersion vents, and a connecting means is disclosed, positioned on the housing for securing the extinguisher assembly to a structure. An adapter further comprised of a first end fastened to the spray nozzle and a second end connected to an extinguisher tank is also disclosed to provide the said connection, therefore the fire retardant agent is expelled directly from the extinguisher tank through to the dispersion vents.

Claims

1. An extinguisher assembly for dispersing a fire retardant agent, comprising:

a. a housing further comprised of dispersion vents for re-directing the fire retardant agent;

b. a spray nozzle secured within the housing for dispersing the fire retardant agent through the dispersion vents;

c. a connecting means positioned on the housing for securing the extinguisher assembly to a structure, and

d. an adapter further comprised of a first end fastened to the spray nozzle and a second end connected to an extinguisher tank;

wherein the fire retardant agent is expelled directly from the extinguisher tank through to the dispersion vents.

2. The extinguisher assembly of claim 1 further comprised of a reducer, connected in between the spray nozzle and the adapter and in threaded engagement with the housing.

3. The extinguisher assembly of claim 1 further comprised of a Schrader valve connected to the adapter.

4. The Schrader valve of claim 3 further comprised of sintered brass to prevent the fire retardant agent from corroding the Schrader valve.

5. The extinguisher assembly of claim 1 further comprised of a pressure switch connected to the adapter.

6. The extinguisher assembly of claim 1 wherein the connecting means is further comprised of a clip connected to a slotted shaft and a pawl operatively connected to the shaft.

7. The extinguisher assembly of claim 1 further comprised of a Printed Circuit Board (PCB) and electronic sensor connected to the PCB.

8. The extinguisher assembly of claim 1 further comprised of heat slits positioned on the outer circumference of the housing.

9. The extinguisher assembly of claim 1 further comprised of a Light Emitting Diode (LED) unit for alerting an occupant of low pressure in the extinguisher tank and remaining battery life.

10. The extinguisher assembly of claim 1 wherein the dispersion vents have an optimal pitch of 7.5 degrees.

11. The extinguisher assembly of claim 1 wherein the adapter is in threaded engagement with the housing.
