Smoke alarm device for fire protection

Abstract

The invention provides a smoke alarm device for fire protection. The smoke alarm device for fire protection comprises a mounting hanging seat, an ATM microcontroller, a motor, a smoke alarm body, mounting holes, blades, a clamping frame, a contact switch, an alarm light, a horn window, elevated support bars, a threading hole and a bottom plate; the mounting hanging seat is uniformly provided withthree stepped mounting holes; the ATM microcontroller is mounted in the inner cavity of the mounting hanging seat; and the motor is disposed on the top surface of the clamping frame by a ring of screws. The device is capable of certain self-protection in case of a fire. In case of the fire, the motor rotates while the device alarms normally; the device is accommodated in a reserved mounting groovein the suspended ceiling through the power output shaft of the motor; in the accommodating process, eight blades in a petal-like structure draw back and protect the device from outside, thereby forming a protective wall to protect the device against heat and endow the device with a self-protective function, and improving the practicability.

Description

technical field [0001] The invention belongs to the technical field of fire safety devices, and more specifically relates to a smoke alarm device for fire protection. Background technique [0002] The structure of the smoke alarm is simple, and the smoke sensor is mostly used as the sensing element, and the smoke emitted by the fire inside the building is used as the sensing medium to achieve the effect of sounding the alarm. [0003] The inventor found similar patents for tree injection in the process of searching for patents. For example, the application number is: 201711165292.4, which mentioned a smoke alarm including a plastic shell, a circuit board, a sealing cover, and a cover plate , light-emitting diodes, phototransistors, nuts and threading holes, characterized in that the plastic housing is a cylindrical structure, the bottom of the plastic housing is open, the sealing cover is buckled on the bottom of the plastic housing, and the sealing cover is processed with t...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above-mentioned technical problems, the present invention provides a smoke alarm device for fire-fighting to solve the above-mentioned problem about the existing smoke alarm. After being installed on the suspended ceiling of a building, it is mostly exposed outside vertically. When an indoor fire occurs, It can only be used as an alarm, but it cannot be protected by itself. When the indoor temperature is too high, it will melt or burn.
