Device for automatically lowering carbon dioxide concentration in car

Abstract

The invention discloses a device for automatically lowering carbon dioxide concentration in a car. The device comprises a carbon dioxide sensor (3), a car window controller (8), a displacement sensor (9) and an alarm (10) and is characterized in that a power supply (1) is connected with a detecting component (6) and a control component which are parallelly connected, the carbon dioxide sensor (3) and an induction coil (4) are mounted on the detecting component (6), a switch (5), a car window control component (7) and the alarm (10) are mounted on the control component, the car window control component (7) and the alarm (10) are parallelly connected, the parts are connected through wires, a fuse (2) is connected to the power supply (1), the induction coil (4) and the switch (5) form a normally open relay, the car window control component (7) comprises the car window controller (8) and the displacement sensor (9), and the power supply (1) is a storage battery. The device is simple in structure, intelligent, reliable, accurate, effective, safe, practicable and suitable for being popularized and used in the lowering of carbon dioxide concentration in the car.

Description

technical field [0001] The invention belongs to the technical field of vehicle intelligent lifesaving devices, and in particular relates to a device for automatically reducing the carbon dioxide concentration in a vehicle. Background technique [0002] Along with the continuous increase of private vehicles, the use safety of automobiles is also increasingly concerned by people, especially children or drunk people who do not have independent lifesaving ability stay in the car, and there is a danger of suffocation before rescue. At home and abroad, it is not uncommon for people to be locked in the car for too long, vomiting, nausea caused by lack of oxygen, and even more serious suffocation and death. [0003] In the prior art, there is an ambulance system for children or drunk people staying in the car, which senses the abnormal situation in the car through vibration, but because the children are young and the drunk people are confused, they may not be too restless when they ...

AI Technical Summary

Problems solved by technology

There are also some lifesaving systems that realize lifesaving through temperature detection. There are many unrealistic reasons for this kind of lifesaving. For example, the car is in an open parking lot exposed to the sun, and false alarms often occur. If the trigger conditions are set too harsh, children may Or it is difficult for a drunk person to trigger it in the car. At the same time, it is affected by the temperature in different regions, and the corresponding life-saving effect can no longer be achieved.
