Vehicle-mounted fresh air system

Abstract

The invention provides a vehicle-mounted fresh air system, which comprises an air inlet opening module, an air outlet opening module, a control circuit module, a storage battery, an infrared detection module, a warning module and a carbon monoxide sensor, wherein the air inlet opening module comprises an air inlet opening filtering purification unit and an air inlet opening fan; the air outlet opening module comprises an air outlet opening fan; the carbon monoxide sensor detects whether the carbon monoxide content in a vehicle exceeds the standard or not; when an abnormal condition occurs, the warning module sends out sound and light to warn; the infrared detection module is used for detecting whether people or animals exist in the vehicle or not; the control circuit module is used for receiving and controlling the work of the whole system; the storage battery is used for storing electric energy; the storage battery is connected with the control circuit module and is connected with an automobile power generator. The vehicle-mounted fresh air system provided by the invention has the advantages that the automatic air exchange in the parking state or the people-free state of the vehicle is realized; the temperature in the vehicle can be reduced; harmful volatile gas (VOC) such as formaldehyde, methylbenzene and ammonia in the vehicle can be eliminated; the effects of eliminating bacteria, removing dust, purifying air in the vehicle and the like are achieved.

Description

technical field [0001] The invention relates to the field of vehicle-mounted instruments, in particular to a vehicle-mounted fresh air system. Background technique [0002] Existing cars on the market, after parking and turning off, will have the following problems: [0003] In the first case, when the car is stagnated outdoors at a relatively high temperature, the interior of the car is a relatively airtight environment, and the temperature inside the car will rapidly rise to 50-65°C with the high temperature outside, and the formaldehyde, toluene, and ammonia in the car will A large amount of harmful volatile gases (VOC) are released; if the user opens the door and enters the car to start the vehicle, the high temperature inside the car is unbearable, and the high concentration of harmful volatile gases will make the user feel very uncomfortable, bringing Potential safety and health hazards, such uncomfortable experience is common among car users; [0004] In the second ...

AI Technical Summary

Problems solved by technology

[0003] In the first case, when the car is stagnated outdoors at a relatively high temperature, the interior of the car is a relatively airtight environment, and the temperature inside the car will rapidly rise to 50-65°C with the high temperature outside, and the formaldehyde, toluene, and ammonia in the car will A large amount of harmful volatile gases (VOC) are released; if the user opens the door and enters the car to start the vehicle, the high temperature inside the car is unbearable, and the high concentration of harmful volatile gases will make the user feel very uncomfortable, bringing Potential safety and health hazards, such uncomfortable experience is common among car users;

[0004] In the second case, after the vehicle is parked for one night, the air in the car is not circulated, and bacteria are easy to breed. If you do not open the window for ventilation before using the car, it will be very uncomfortable;

[0005] In the third case, if children stay in the car for a long time, problems such as high temperature and hypoxia will occur, and dangerous cases frequently occur

[0006] Existing cars do not turn off the engine when they are parked in a closed space (such as an underground garage), and passengers continue to use the car air conditioner, which can easily cause carbon monoxide poisoning of the passengers in the car

[0007] At present, there is no good solution to the above problems on the market
