self-protecting smoke alarm

Abstract

The invention discloses a smoke alarm capable of self-protection, which comprises an alarm body. The alarm body is detachably connected, and at least two protective blades are arranged around the alarm body. The upper parts of the plurality of protective blades are connected with the same blade opening and closing device, and the blade opening and closing device is arranged in the mounting seat. Compared with the prior art, the present invention is compact in structure and strong in practicability, and the user can simply and conveniently realize the installation, fixation and disassembly between the mounting seat and the fixing seat through the cooperation of the fixing seat lock piece and the horizontal clamping rod, which is stable and stable. The effect is good, the removal efficiency is high, and the operation is simple and labor-saving; at the same time, in case of fire, the protective blades can be shrunk and protected on the outside of the alarm to form a protective wall, so as to provide certain heat insulation protection for the device, so that the device itself is also protected. It has its own protection function.

Description

technical field [0001] The invention relates to the technical field of alarms, in particular to a self-protecting smoke alarm. 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, and thus invented the smoke alarm, also known as fire smoke alarm, smoke alarm or smoke sensor, which is 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 surface of other supp...
