One is the different audience structure. The foreign auto show visitors are mainly professional visitors, while the domestic auto show is dominated by the public.
The second is that foreign auto shows do not have such a trouble in the domestic auto show. There are also beautiful models on the foreign auto show scene, but there is not so much noise in the venue and it is relatively quiet. The domestic auto show is more like a carnival, like a big PARTY.
Thirdly, the press conference of the foreign auto show was well organized. One by one, the media did not feel too nervous. Almost all the press conferences of the Shanghai Auto Show were arranged on the first day of the media day, which made the reporter exhausted.
Fourth, foreign auto shows do not have as many brands as domestic auto shows. The overseas auto show is mainly international big brands, with a limited number. In addition to the full participation of international brands in domestic auto shows, there are domestic independent brands and joint ventures' own brands.
The car purifier is also called a car purifier or a car Air Purifier, which usually consists of a high-voltage generating circuit negative ion generator, a micro fan, an air filter and other systems. Its working principle is as follows: the micro-fan (also known as ventilator) in the machine circulates the air in the car, and the polluted air passes through the PM2.5 filter and activated carbon filter in the machine to filter or adsorb various pollutants, and then After the negative ion generator installed at the air outlet (the high voltage in the negative ion generator generates DC negative high voltage during operation), the air is continuously ionized to generate a large number of negative ions, which are sent out by the micro fan to form an air flow of negative ions to achieve the purpose of cleaning and purifying the air.
