It is designed to be thrown a distance so that it can reach areas of difficult access and project the extinguishing agent achieving a fast extinguishing, it consists of a body (1) of spherical configuration in turn comprising a lower tank (4) which has a partially spherical configuration housing the extinguishing agent, which is formed by a first half-body (5) and a second half-body (5′) joined together, and an upper spray cap (7) equipped with spray nozzles (8) which are joined to the lower tank (4), and a solenoid valve (3) automatically or manually activated by remote control which allows the passage of the circulation of the extinguishing agent from the tank (4) to the spray nozzles (8) for its mass propagation from said spray nozzles (8) towards the exterior to extinguish the flames.

There is provided a fire extinguisher comprising a fire extinguishing agent; a first mechanism configured to operate said fire extinguisher via a manual operation; a second mechanism configured to operate said fire extinguisher automatically; and wherein said fire extinguisher comprises at least one detector to detect the existence of a fire and cause the operation of said second mechanism.

A fire suppression device may be launched from a hand-held, stand alone, or object- or vehicle-mounted device. The fire suppression device may be propelled by a first accelerant ejected out of a proximal end of the fire suppression device. The fire suppression device may be ruptured by a second accelerant after a predetermined amount of time. A fire suppressant may be dispersed on a fire when the fire suppression device is ruptured.

The invention discloses a unidirectional spray type fire extinguishing bomb without high explosive fragmentation, includes a housing, a fuse, an igniter, an fire extinguishing agent and a main charge, and further includes a tail braking device, combustor, a plate closure, a piston and a diffuser. The housing, the tail braking device and the piston are made of light metal materials; the housing is cylindrical; the tail braking device is arranged at the bottom of the housing and is fixed with the housing through a screw nail; and the fuse is arranged on the diffuser and is fixed through a screw nail. During working process, when the fuse detects the fire extinguishing bomb to be 5-10 meters far away from a combustion source, the igniter ignites the main charge, the piston is pushed under high pressure to move in the housing, and the fire extinguishing agent is sprayed out from spraying holes to the combustion source for fire extinguishing. The present invention has simple structure, and has no lethality when the fire extinguishing agent is sprayed.

The present disclosure provides a throwing device with a launcher and a propulsion system. The propulsion system comprises a retardant set between two sections of propellant for delaying the combustion and reducing the generated smoke or heat while launching the propulsion system. The launcher comprises: a tube for containing the propulsion system; and a trigger for triggering the ignition cartridge. A screw hole is in center of a bottom of the first chamber; nozzles are located around the screw hole; and a collar with a hole fixed in the bottom of the first chamber, wherein the ignition cartridge is fixed in the screw hole by the collar. The ignition cartridge comprises an explosive primer, and the launcher further comprises a firing pin triggered by the trigger to hit the explosive primer.

The present disclosure provides a propulsion system with a retardant set between two sections of propellant for delaying the combustion and reducing the generated smoke or heat while launching the propulsion system.

A portable fire extinguishing apparatus, which comprises a casing (20) and a cartridge (3) arranged inside the casing (20). The top end of the cartridge (3) is fixedly connected with the casing (20) through a snap ring (24); the bottom of the cartridge (3) is fixedly connected with the casing (20) through some nuts and bolts; and an explosion venting unit (2) is arranged at the jet end of the cartridge (3). Kinetic energy generated from explosion is consumed through shifting and limiting processes of the explosion venting units (2), therefore recoil force or forward impact force generated after explosion of explosives can be consumed or released, so that safe and effective explosion venting is achieved and hurt to human bodies or articles after explosion of grains is avoided.

Disclosed herein is a solid aerosol detonator capable of generating a fire extinguishing gas by vaporizing an internal solid fire extinguishing agent in order to extinguish a fire which may be generated in a place to live or an industrial place and a fire extinguishing apparatus using the same. The solid aerosol detonator and the fire extinguishing apparatus using the same can be detonated using only a fire extinguishing agent of a solid form without using an electronic match or an ignition agent, that is, a material coated on an electrical percussion. Accordingly, the combustion action of a solid aerosol can be stably generated because the solid aerosol detonator and the fire extinguishing apparatus using the same are not sensitive to a change in the physical properties and a change in the temperature even after a lapse of a specific time.
