Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of air purification, and particularly relates to a vehicle air disinfection and sterilization purifier based on the Internet of Things, and also relates to a purifying method using the purifier. BACKGROUND

[0002] The vehicle is mainly an important tool for facilitating the travel of personnel, and generally mainly includes long-distance buses, buses and rail trains. The space of these vehicles is small and the personnel flow is dense, which is a place where bacteria and viruses are easily transmitted. Moreover, due to the large flow of personnel, the source of bacteria and viruses cannot be determined. At present, the air purification of the vehicle mainly has the following ways: 1. Artificial spraying of disinfectant for disinfection and sterilization. This disinfection and sterilization method can only be used for overall disinfection and sterilization when the vehicle stops running, which can ensure that the air in the running space is clean, but disinfection and sterilization cannot be performed during running. 2. The vehicle is purified by using an air purifier. For example, a rear-mounted vehicle air purifier based on the Internet of Things is disclosed in the patent file with the patent number 201820157507.1. The air purifier is designed in a strip shape and can be installed behind the rear seat of the car, without affecting the space in the car. However, this air purifier still has the following shortcomings: first, the structure of the air purifier is flat, and the internal space is very small, so there is not much space to install the electrostatic chamber, the activated carbon bin and the negative ion generating chamber. This design is unreasonable. Secondly, the air purifier has a large air flow resistance through the air inlet pipe and the air outlet pipe, so the air flow is small, which cannot meet the requirements of the use of the air purifier in, for example, buses, long-distance buses and rail vehicles. The disinfection and sterilization time is slow, and the virus and bacteria purification rate is low. Thirdly, the air flow resistance is large, and the back pressure of the fan is also large, so the speed of the fan needs to be increased to ensure a certain air output, and the noise is also large.
