Description

Technical Field

[0001] The utility model relates to the technical field of in-vehicle odor monitoring, in particular to a sensor device for in-vehicle odor monitoring. Background Art

[0002] Currently, cars lack hazardous gas warning systems. When a large number of people are inside a vehicle with its doors and windows closed, the carbon dioxide concentration inside the vehicle rises rapidly. A carbon dioxide concentration exceeding 2% can cause dizziness, 5% can cause nausea, vomiting, and difficulty breathing, and over 8% can lead to death. If the air conditioner is running while the vehicle is stopped, especially in poorly ventilated areas, the air conditioner can draw exhaust fumes into the vehicle, causing a rapid rise in carbon monoxide concentrations and potentially causing carbon monoxide poisoning for the driver and passengers. Both carbon dioxide and carbon monoxide are colorless and odorless, making elevated concentrations difficult to detect, posing a threat to the driver's safety and the lives of those inside. Furthermore, the materials used in vehicle interiors can emit toxic gases such as formaldehyde, which, when their concentrations reach a certain level, can also pose a health hazard to those inside. To address the problem of elevated carbon dioxide and carbon monoxide concentrations being difficult for drivers and passengers to detect, and to detect in real time whether toxic gases such as formaldehyde exceed permitted levels, a sensor device for monitoring odors inside a vehicle is being developed.

[0003] The harmful gas warning device in the car disclosed in the publication number CN202929006U can monitor the concentration of harmful gases in the car in real time. When the concentration of harmful gases in the car is about to reach a value harmful to the human body, it can promptly issue reminders to the people in the car, thereby ensuring the safety of the people in the car.

[0004] However, the harmful gas warning device in the vehicle has the following disadvantages:

[0005] (1) When monitoring harmful gases in a vehicle, the harmful gases need to float to the surface of the sensor module and contact the sensor module before the sensor module can detect the harmful gases and issue an alarm. However, the floating speed of the gas is too slow, making it take too long to detect and issue an alarm.

[0006] (2) The process of installing the device into the vehicle is relatively complicated, which makes it inconvenient to disassemble and maintain it later. Utility Model Content

[0007] (1) Technical problems solved

[0008] The technical problem solved by the utility model is to provide a sensor device for monitoring odors in a vehicle, which is highly practical, can be easily operated, and has a relatively simple structure. It solves the problem proposed in the above-mentioned background technology that the floating speed of the gas is too slow, resulting in a long time for monitoring and issuing an alarm, and the process of installing it in the vehicle is relatively complicated, resulting in inconvenience in subsequent disassembly and maintenance.
