Ventilation protection system preventing anoxia and carbon monoxide poisoning

Abstract

The invention provides a ventilation protection system preventing anoxia and carbon monoxide poisoning. The system comprises a system host and a draught fan. An intelligent controller, a rechargeablebattery, a sampling sucking pump, a gas ingredient detector, a commercial power interface, an electro-optic alarm and / or an electro-sound alarm are arranged in the system host. Needed power transformation, power supply and control circuits and modules or processing parts are arranged in the intelligent controller and connected with and control the draught fan, the sampling sucking pump, the gas ingredient detector, the commercial power interface and the rechargeable battery, during commercial power supply, normal operation of the ventilation protection system is kept and the electricity amountof the rechargeable battery is guaranteed by the intelligent controller through commercial power during commercial power supply, and when commercial power supply is interrupted, the intelligent controller carries out automatic switching to keep emergency operation of the ventilation protection system through the electricity amount of the rechargeable battery. The draught fan is mounted on a wallbody or a window or a ventilation hole way of a ventilation pipeline.

Description

technical field [0001] The invention relates to a ventilation protection system, in particular to a ventilation protection system for preventing hypoxia and carbon monoxide poisoning. Background technique [0002] Carbon monoxide poisoning, because it often occurs unconsciously, people with carbon monoxide poisoning are often incapacitated, so the injuries and consequences are often serious. Carbon monoxide poisoning that occurs indoors is commonly known as gas poisoning. It is mainly caused by the blockage of the flue or chimney during the cooking and heating process of coal-fired stoves and gas stoves, or the poor discharge of flue gas. Sometimes it is caused by unreasonable installation and use of gas water heaters. Caused; especially during occasional power outages, carbon monoxide poisoning is more likely to occur if you continue to use supporting electric exhaust equipment such as range hoods, exhaust fans for coal-fired stoves, gas stoves, and gas water heaters.

AI Technical Summary

Problems solved by technology

[0008] In the prior art, the smart exhaust fan device for preventing carbon monoxide poisoning usually uses grid power as the power source, and the carbon monoxide concentration cannot be detected when the grid is powered off, and the exhaust fan cannot be started and operated, and cannot prevent carbon monoxide poisoning. ; On the other hand, the types of gas component detectors used or the types of detected gas components are often relatively single or less, or there are too many alarm thresholds, control action thresholds or corresponding control logics of the detected gas component content. Simple or unreasonable, so in some cases it is impossible to timely alarm, ventilate and prevent hypoxia suffocation and carbon monoxide poisoning
