Smoke alarm with high availability

Abstract

The invention discloses a smoke alarm with high practicability. The top of the alarm body is fixedly connected with a mounting seat, the top of the mounting seat is provided with a fixing seat, the top of the fixing seat is fixedly connected with the ceiling, and the mounting seat and the fixing seat are detachably connected. A blade protection device is arranged around the alarm body, a screw drive motor is installed in the inner cavity of the mounting seat, a guide screw is vertically fixed on the output shaft, and the upper end is connected with a clamping assembly of the fixing seat, and the thread on the guide screw is A vertical guide slider is connected, and the vertical guide slider is provided with a fixing seat stabilizing component. Compared with the prior art, the present invention has compact structure and strong practicability, and the user can easily and conveniently realize the installation, fixation and disassembly between the mounting seat and the fixing seat, with good stabilizing effect, high disassembly efficiency, simple and labor-saving operation; at the same time, the The protective blade shrinks and protects the outside of the alarm, forming a protective wall, so that the device is protected from heat to a certain extent, so that the device itself also has its own protection function.

Description

technical field [0001] The invention relates to the technical field of alarms, in particular to a smoke alarm with high practicability. Background technique [0002] Fire refers to a catastrophic burning phenomenon that is out of control in time or space. Among various disasters, fire is one of the main disasters that most often and most commonly threaten public safety and social development. Human beings can use and control fire, which is an important symbol of the progress of civilization, so smoke alarms were invented, also known as fire smoke alarms, smoke alarms or smoke sensors, etc., which are powered by the bus, and multiple , network and communicate with the fire alarm controller to form an alarm system. There is no sound at the scene when the alarm is triggered, and the host has sound and light prompts. [0003] Defects of the prior art: At present, the commonly used installation methods for smoke alarms are mostly to fix the smoke alarms to the wall or the surfac...
