Abstract

The invention relates to a safety fuse starting device and a fire extinguisher. The safety fuse starting device comprises a shell which is provided with a first cavity, a second cavity and a heat conduction part located between the first cavity and the second cavity, and the shell is provided with a lead-out hole communicating with the first cavity; and the safety fuse starting device further comprises a first safety fuse with one end penetrating into the first cavity through the lead-out hole, and the other end arranged at a protection area, and a second safety fuse with one end arranged in the second cavity, and the other end used for extending to gas generating agents. Thus, heat generated by the first safety fuse in the first cavity is transmitted to the second cavity through the heat conduction part, and the second safety fuse is ignited; then, the gas generating agents are started through the second safety fuse, and the second safety fuse does not need to be directly led out from the second cavity to the protection area, and gas generated by the gas generating agents is prevented from leaking out; and the starting device is favorable to improvement of the fire extinguishing effect of the fire extinguisher.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing equipment, in particular to a fuse starting device and a fire extinguisher. Background technique [0002] Fire extinguishers generally include pressure storage type and non-pressure storage type, and the non-pressure storage type fire extinguisher greatly improves safety because it does not need to store pressure. Generally, in the non-pressure storage type fire extinguishing device, the thermal wire is used to ignite the starting agent, and then the fire extinguisher is activated. However, the thermal wire needs to be drawn from the inside of the fire extinguisher, so a reserved hole needs to be opened. When the thermal wire burns into the fire extinguisher, the reserved hole is in an unsealed state, so that part of the gas generated by the starting agent will be sprayed out of the reserved hole, thereby reducing the eruption force of the fire extinguisher and affecting the fire exting...
