[0002] With the improvement of people's living standards, cars have become a necessary means of transportation for families. At present, the built-in air conditioners in cars generally only have cooling, heating and ventilation functions. However, with the increasing prominence of environmental problems, the presence of haze and pollutants in the air, when people drive, the poor air quality in the car can easily affect people's respiratory system. Therefore, it is necessary to install corresponding car air conditioner vent purifiers at the car vent position. In order to improve the use efficiency of car air conditioner vent purifiers, a micro-electrostatic filter is needed, but the existing micro-electrostatic filter still has the following shortcomings:

[0003] For example, the utility model with application number 201820842912.7 discloses a vehicle-mounted air purifier, which utilizes the circulation of the automobile air-conditioning outlet to purify the air. It does not require power, external power, or its own power to purify the automobile air. However, similar to the comparative documents of the above-mentioned application, when the existing micro-electrostatic filter is used, most of the micro-electrostatic filters are not easy to quickly adsorb particulate matter in the air, which affects the air purification effect, resulting in reduced practicality and reduced efficiency of the micro-electrostatic filter.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a micro-electrostatic filter is proposed. Utility Model Content

[0009] Furthermore, the outer side of the discharge electrode is flush with the outer side of the electrode metal plate, and the front end of the discharge electrode is tightly fitted with the rear side of the electrode metal plate.

[0010] Furthermore, the installation component includes an installation slot, an installation slider and a docking mortise. The installation slot is internally connected to the installation slider, and the main shell has four internal corners with docking mortise.

[0016] 2. Through the setting of the installation component, the utility model can slide the installation frame into the main shell when the micro-electrostatic filter is in use by means of the installation groove opened inside the main shell and the installation slider added outside the installation frame, thereby limiting the installation of the micro-electrostatic filter, and facilitating subsequent maintenance and disassembly.
