FIRE EXTINGUISHING DEVICE, FIRE EXTINGUISHING SYSTEM COMPRISING FIRE EXTINGUISHING DEVICE, FIRE EXTINGUISHING METHOD INVOLVING USE OF FIRE EXTINGUISHING DEVICE, AND DETONATOR FOR FIRE EXTINGUISHING DEVICE Russian patent published in 2025 - IPC A62C19/00 F42C19/08 B64D1/16 

FIELD: fire-fighting equipment.

SUBSTANCE: group of inventions relates to the field of fire extinguishing, namely to a fire extinguishing device, to a fire extinguishing system containing such a device, to a fire extinguishing method, which includes a step of dropping at least one said fire extinguishing device, and to a detonator for the fire extinguishing device. Fire extinguishing device comprises a housing which defines the boundaries of an inner cavity in which the at least one dispersible fire extinguishing substance is located; and a pyrotechnic agent suitable for initiating an explosion causing said housing to rupture and spraying said dispersible fire extinguishing substance; wherein said pyrotechnic means comprises: at least one explosive charge generating said explosion; and a detonator causing said at least one explosive charge. Said detonator comprises: an ignition device configured to initiate said explosion, said at least one explosive charge while in an active state; and a shock sensor configured to detect a mechanical shock perceived by said fire extinguishing device, and switching said ignition device into said active state after detecting said mechanical shock. At that, the ignition device is an electrical ignition device and the impact sensor is an electrical module connected to the said electrical ignition device, electrical module comprises: an accelerometer type sensor, a power supply and a control means interacting with the accelerometer type sensor, and the electric ignition device includes an igniter cap, which interacts with said at least one explosive charge indirectly through a pyrotechnic fuse, which connects said cap igniter head and said at least one explosive charge, or directly within said at least one explosive charge.

EFFECT: broader functional capabilities.
