Photoelectric smoke detection alarm based on Internet of things

Abstract

The invention discloses a photoelectric smoke detection alarm based on the Internet of things. The photoelectric smoke detection alarm comprises a shell, a control center assembly, photoelectric infrared pair tubes and a micromotor, wherein the interior of the shell is successively provided with the control center assembly and the photoelectric infrared pair tubes from top to bottom; an optical maze is arranged between the photoelectric infrared pair tubes in the shell; the micromotor is fixedly mounted at the center of the top of the shell; an isolation net is paved on the top of the shell; an isolation pipe is fixed at the edge of the bottom of the shell; an air inlet pipe is mounted on the outer wall of the top of the isolation pipe in a penetrated mode; a brush rod is mounted below theouter wall of the output shaft of the micromotor through a one-way bearing; and the rod end of the brush rod is fixedly connected with a sweeping rod. According to the photoelectric smoke detection alarm based on the Internet of things, the insensitivity of the alarm to smoke inhalation caused by dust in air can be effectively avoided, the influence of the dust on detection work is reduced, and the working efficiency and working timeliness of the alarm can be improved.

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
