Description

Technical Field

[0001] The utility model relates to the technical field of air purification, in particular to a disinfection and sterilization module for purifying the air quality in a vehicle. Background Art

[0002] With the continuous improvement of people's living standards, cars have become an important means of transportation for people's daily travel. The air quality in the car is crucial for the health of the driver and passengers. However, currently, there is usually no integrated plasma or negative ion disinfection and sterilization module in the vehicle air conditioner or ventilation duct; under the existing technical conditions, in order to improve the air quality in the car, people often need to purchase plasma air purifiers or negative ion air purifiers externally. Such external purification devices have many problems; firstly, they need to occupy a certain amount of space in the car. In the case where the space in the car is already limited, the additional placed purification device may affect the cleanliness and comfort of the car; secondly, in order to ensure the firm and stable placement of the device, some fixing measures need to be taken, which not only increases the complexity of installation, but may also become loose due to bumps and other reasons during vehicle driving, and even pose a safety hazard.

[0003] More importantly, the external plasma air purifier or negative ion air purifier cannot conform to the flow of the air in the car. The air flow in the car is a complex process, and it is difficult for the external device to perfectly cooperate with the air flow system in the car, which results in its inability to quickly act on every corner of the car, and the purification effect is greatly reduced. Some areas may not be effectively purified because the air flow is difficult to reach, which limits the overall improvement of the air quality in the car.

[0004] In addition, since the external device operates independently of the vehicle air conditioner or ventilation system, it cannot achieve intelligent coordinated control. This makes it impossible to accurately adjust the air purification according to the actual situation in the car in different usage scenarios, and cannot meet people's needs for a high-quality in-car air environment. In summary, there is an urgent need for an in-car air purification technology that can effectively solve the above problems to improve the air quality in the car and provide a healthier and more comfortable travel environment for the driver and passengers.
