Description

Technical Field

[0001] The utility model relates to the technical field of fire protection, in particular to a fire protection induction detection fire extinguishing device. Background Art

[0002] Fire refers to a catastrophic combustion phenomenon that is out of control in time or space. Among various disasters, fire is one of the most frequent and common major disasters that threaten public safety and social development.

[0003] According to a fire-fighting induction detection fire extinguishing device disclosed in Chinese patent publication number CN 115779315 B, the patent solves the problem that when a fire occurs, the temperature of the fire is very high and there are too many electronic devices, which causes the high temperature of the fire to damage the electronic devices. The patent sets a protective shell on the outside to block the high temperature of the outside, avoiding the internal electronic components from being directly subjected to the high temperature, and the high temperature is monitored by the mercury in the mercury tube. The setting of mercury cancels the monitoring of the electronic device, ensuring that an alarm can be given when a fire occurs, avoiding the situation where the electronic device may be damaged by the high temperature and cannot be monitored, and then the fan blades are driven to rotate by starting the motor, and then the fan blades suck and discharge the dry powder. The dry powder disperses after being discharged, and the diffusion of the dry powder plays a role in slowing down the fire, which has a certain effect on extinguishing the fire, and the starting of the motor will also drive the shaking of the bell, thereby generating a sound, which has the effect of an alarm. However, when the dry powder is sprayed out from the upper end of the fire extinguisher, part of the dry powder will be sprayed on the ceiling, thereby wasting the dry powder, and the spraying range of the dry powder is limited, resulting in poor fire extinguishing effect.

[0004] To this end, we propose a fire-fighting induction detection fire-extinguishing device to solve the problem of wasting dry powder and reducing fire-extinguishing performance in the above-mentioned device. Utility Model Content
