Description

Technical Field

[0001] The present invention relates to the technical field of filter components for automobile air purifiers, and in particular to a filter component for automobile air purifiers. Background Art

[0002] A car purifier, also called a car purifier or car air purifier, typically consists of a high-voltage negative ion generator, a micro-fan, and an air filter. Its working principle is as follows: The micro-fan (also called a ventilator) inside the machine circulates air inside the vehicle. Polluted air passes through the PM2.5 filter and activated carbon filter, filtering or adsorbing various pollutants. The air then passes through the negative ion generator installed at the air outlet (the high voltage in the negative ion generator generates a DC negative high voltage during operation), which continuously ionizes the air and produces a large number of negative ions. These are then transported out by the micro-fan, forming a negative ion airflow, achieving the purpose of cleaning and purifying the air.

[0003] The existing car air purifier filter components have poor air purification effects, short service life, need to be replaced frequently, and have a short service life. In addition, the air purification components are not replaced and cleaned in time, resulting in reduced air purification effects. The functions are single and there is no dust collection function.
