The present invention relates to a novel hand-held aerosol fire suppression apparatus, comprising thermal insulating layer, inner cylinder, aerosol generating agent, heat insulating material, jet nozzle, tapered jet orifice, enclosure, ignition head and piezoelectric crystal assembly, wherein the thermal insulating layer is arranged between the inner cylinder and the aerosol generating agent, and the jet nozzle is screwed to the enclosure by means of a thread structure that comprises 3~6 thread segments. Compared to that in the prior art, with the segment thread design for screwing the jet nozzle to the enclosure, the time required for removing the jet nozzle can be reduced significantly, and therefore the apparatus in the present invention has much better safety feature against accidents.

L'invention concerne un nouveau dispositif portable de lutte contre le feu comprenant une couche d'isolation (3), un cylindre interne (4), un agent de génération d'aérosol (5), un matériau d'isolation thermique (6), une tête de pulvérisation (9), un orifice contractile (10), une enveloppe (11), une tête d'allumage (12), et un ensemble de cristaux piézo-électriques (13). La couche d'isolation (3) est située entre le cylindre interne (4) et l'agent de génération d'aérosol (5), et un filetage de vis qui relie de manière rotative la tête de pulvérisation (9) à l'enveloppe (11) est un filetage à segments comprenant 3 à 6 segments. Par rapport à l'état de la technique, la conception du filetage à segments qui relie de manière rotative la tête de pulvérisation à l'enveloppe réduit grandement le temps nécessaire pour dissocier la tête de pulvérisation afin d'empêcher la survenue d'un accident et d'améliorer significativement la sécurité.
