A photoelectric smoke detection alarm based on the Internet of Things

Abstract

The invention discloses a photoelectric smoke detection alarm based on the Internet of Things, which includes a casing, a control center component, a photoelectric infrared pair tube and a micro motor. The inside of the casing is sequentially arranged with a control center component and a photoelectric infrared Pair tubes, and an optical labyrinth is arranged between the photoelectric infrared tubes inside the shell, the micro motor is fixedly installed at the top center of the shell, and an isolation net is laid on the top of the shell, and an isolation net is fixed on the bottom edge of the shell. The outer wall of the top of the isolating tube is provided with an air intake pipe, and the outer wall of the output shaft of the micromotor is provided with a brush rod through a one-way bearing, and the rod end of the brush rod is fixedly connected with a sweeping rod. The photoelectric smoke detection alarm based on the Internet of Things can effectively prevent the dust in the air from causing the alarm to be insensitive to smoke inhalation, reduce the impact of dust on the detection work, and improve the working efficiency and timeliness of the alarm.

Description

technical field [0001] The invention relates to the technical field of photoelectric smoke detection alarms, in particular to a photoelectric smoke detection alarm based on the Internet of Things. Background technique [0002] Smoke detection alarm is an equipment tool for intelligent fire alarm processing in the existing society. It is mainly divided into two types: ion smoke alarm and photoelectric smoke alarm. , can urgently issue fire warnings, carry out fire early warning processing, effectively avoid the occurrence of fires due to unknowable fire spread, so as to facilitate artificial control of fire fires, fundamentally carry out timely early warning and fire extinguishing, and reduce the problem of fire spread Economic property loss and hidden dangers to personal health and safety. [0003] However, the existing smoke detection alarms have the following problems in use: [0004] 1. For example, the smoke alarm shown in the comparative patent "CN204406599U, a photoe...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a photoelectric smoke detection alarm based on the Internet of Things to solve the above-mentioned background technology. It is proposed that when the existing smoke detection alarm is used for a long time, a large amount of dust is easy to accumulate at the air inlet of the smoke alarm, forming The blockage of the airflow makes the alarm not sensitive enough when inhaling the smoke, resulting in untimely alarm processing and response, and there are defects in use. Detection, prone to dust problems and smoke absorption efficiency problems, the alarm response value does not exceed the preset smoke threshold in the alarm, so that the alarm does not work in time, resulting in detection errors that cause the fire to expand and then respond
