Abstract

The invention provides an independent fire detection alarm, and mainly relates to the field of fire alarm equipment. The independent fire detection alarm comprises a base, a bottom cover is movably installed on the base, a main body structural member is installed on the bottom cover through a buckle structure, a circuit board is fixedly installed in the middle of the main body structural member, a battery bin and an SIM card holder are arranged on the two sides of the circuit board on the main body structural member respectively, and an optical maze assembly is installed on the circuit board. An upper cover is movably installed outside the main body structural member on the bottom cover, a baffle is arranged in the upper cover, a work indicating lamp is installed in the main body structural member in an embedded mode, the optical maze assembly comprises a maze cover and a maze body, and a shading cover is arranged in the maze cover. The beneficial effects of the invention are that the optical maze and the buzzer are fused together, and a sound device and a photoelectric device share one cavity, thereby reducing the size of the device on the basis of guaranteeing the excellent performance of the alarm, and reducing the production cost.

Description

technical field [0001] The invention mainly relates to the field of fire alarm equipment, in particular to an independent fire detection alarm. Background technique [0002] The current smoke detection technology has existed in China for 30 years. Since the introduction of photoelectric smoke detectors in 1997, it has become popular in the domestic market with its green, environmental and pollution-free advantages, and ion detectors have gradually withdrawn from the mainstream. Until now, only a few special areas continue to use ion-type smoke detectors, and photoelectric smoke detectors are used in other places. [0003] In the past two decades, the size of the optical labyrinth of photoelectric smoke detectors has become smaller and smaller, with various forms, and most of them are mainly in the form of detecting scattered light. With the rise of independent photoelectric smoke detection alarms in recent years, although the diameter of the smallest smoke detection optical...
