Smoke alarm with high practicability

Abstract

The invention discloses a smoke alarm with high practicability. An installation base is fixedly connected to the top of an alarm body, a fixing base is arranged on the upper surface of the installation base, the top of the fixing base is fixedly connected with a ceiling, the installation base and the fixing base are removably connected, and a vane protection device is arranged around the alarm body; and a lead screw driving motor is installed in an inner cavity of the installation base, a guiding lead screw is vertically and fixedly connected to an output shaft of the lead screw driving motor,a fixing base clamping assembly is connected to the upper end of the guiding lead screw, a vertical guiding sliding block is connected to the guiding lead screw in a threaded mode, and a fixing basestabilizing assembly is arranged on the vertical guiding sliding block. Compared with the prior art, the smoke alarm has the advantages that the structure is compact, the practicability is high, a user can easily and conveniently achieve installation, fixing and removal between the installation base and the fixing base, the stabilization effect is good, the removal efficiency is high, and operation is easy and capable of saving labor; and meanwhile, protection vanes can be telescoped and form protection on the outer side of the alarm to form a protection wall, and therefore the device can achieve certain heat insulation protection and achieve a self 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 sur...
