Definitions
- the present invention relates to a portable aerosol fire-extinguisher of the type comprising a hollow casing defining in its interior a chamber for housing a solid substance which can be transformed, at a predetermined temperature, into an aerosol with flame-extinguishing properties, and which can be discharged in aerosol form through an opening which puts the chamber housing the extinguishing charge into communication with the exterior.
- a portable fire-extinguisher of the above-mentioned type is known, for example, from patent publication WO-00/37142.
- an electrical resistor supplied by batteries, via a switch, is provided for triggering the transformation of the extinguishing charge from solid to aerosol.
- Fire-extinguishers of the above-mentioned type have a disadvantage which is connected with the limited endurance of the batteries over time. As is known, batteries in fact become discharged after a number of months and, unless the user remembers to replace them periodically, there is a risk that the fire-extinguisher will not operate when required because the batteries are discharged.
- the extinguishing charge 5 is a compacted mixture comprising potassium nitrate, a binding resin, and an organic oxidizing agent.
- a metal plug 6 is fixed at the distal end 3a of the tubular metal casing 3 and forms a delivery opening or nozzle 7 which puts the internal chamber 4 into communication with the exterior.
- both the casing 3 and the plug 6 are made of metal, for example, aluminium.
- a perforated metal diaphragm 8 Directly on the inner side the plug 6, there is a perforated metal diaphragm 8 with a solid central portion 8a and one or more lateral holes 8b the purpose of which will be explained below.
- the extinguishing charge 5 is shaped so as to form a longitudinal duct or passage 9.
- Terms indicating directions and orientations such as “longitudinal” and “transverse” or “radial” are intended to be understood herein with reference to the longitudinal central axis X of the fire-extinguisher, unless indicated otherwise.
- terms such as “front” and “rear” refer to the distal portion and to the proximal portion of the fire-extinguisher, respectively, with reference to the normal condition of use in a user's hands.
- the longitudinal passage 9 puts the distal end 5a of the aerosol-forming charge 5 into communication with the central portion of the fire-extinguisher where, according to the invention, an explosive-capsule starting device is provided.
- An explosive capsule 10 is held in a front compartment 11 formed by a tubular insert 12 mounted centrally inside the supporting body 1.
- a firing mechanism, generally indicated 13 comprises a striker element 14 with an enlarged head 14a housed coaxially inside the insert 12 and a striker-operating spring 15, interposed between the head 14a and a reaction surface 16 which is oriented transversely relative to the principal longitudinal axis of the fire-extinguisher.
- the reaction surface 16 is formed by a cup-shaped body 17 which is housed in the supporting body 1, to the rear of and adjacent the insert 12.
- the cup-shaped body 17 forms a cavity 18 which is open at the rear.
- a resilient, fork-shaped retaining element 21 at least partially housed in the rear cavity 18 of the cup-shaped body 17 has two arms 20a, 20b which can open out resiliently and the free ends 19a, 19b of which are engaged in a hooking arrangement against an enlarged portion 14b formed at the proximal or rear end of the striker 14.
- the arms 20a, 20b are held in the parallel condition illustrated in the drawing by the wall of the rear cavity 18.
- the operating principle of the fire-extinguisher is based on the chemical reaction which, when triggered by the starting device constituted by the explosive capsule 10 and by the striker mechanism 13, brings the mixture of potassium salts to a temperature of about 300°C, giving rise to an exothermic reaction which produces an aerosol suspension of particles of extremely small particle size; these particles, which are discharged from the chamber 4 through the nozzle 7 owing to the pressure which accompanies the reaction, are spread over the source of a fire, inhibiting the combustion-supporting' effect of oxygen and suffocating the propagation of the fire.
- the fire-extinguisher operates as follows.
- the user sees the need, he grips a gripping ring 22 and pulls the fork-shaped element 9, by means of a cord 23, in the direction indicated by the arrow A in the drawing.
- the element 9 moves backwards, sliding along the cavity 18, withdrawing the striker element 14 by means of the hooked ends 19a, 19b and compressing the spring 15.
- the arms 20a, 20b snap apart, releasing the enlarged rear end 14b of the striker which is acted on by the spring and returns sharply to the initial position shown in the drawing, striking the starting capsule 10, which explodes.
- the small flare resulting from the explosion of the capsule 10 is propagated through the duct 9 in the extinguishing charge, reaches the flame-diffuser diaphragm 8 and is reflected thereby, so as to be radiated against the distal end portion 5a of the extinguishing charge 5, triggering its chemical reaction.
- the aerosol fluid produced by the combustion of the extinguishing charge is discharged energetically from the hole 7a in the delivery plug and can be directed towards the fire.
- the effectiveness of the fire-extinguisher according to the invention can be guaranteed for much longer periods of time than in conventional fire-extinguishers of the type discussed in the introductory portion of the present description and the fire-extinguisher does not require any maintenance or periodic checks.
- the details of construction of the fire-extinguisher may be varied widely with respect to those described and illustrated.
- the selection to form the passage duct in the central portion of the extinguishing charge constitutes a preferred selection but is certainly not essential for the purposes of the implementation of the invention.
- the passage 9 could alternatively be arranged in a lateral position rather than a central position, at the interface between the explosive charge and the metal casing 3, for example, by the formation of a longitudinal groove along one side of the extinguishing charge 5 and/or by suitable shaping of the casing 3.
- the selection to form the fire-extinguisher in a manner such that the reaction which produces the aerosol starts in the distal portion of the extinguishing charge also constitutes a preferred selection since it enables the temperatures to be lower in the region closer to the handle, in comparison with an alternative configuration in accordance with which the triggering reaction would start in the immediate vicinity of the explosive capsule 10 and the aerosol would reach the nozzle 7 by being propagated through the passage 9.
- the diffuser diaphragm 8 may be eliminated and its functions may be performed by the internal surface of the delivery plug 6.
