Description

This application is the National Stage Application of PCT/CN2021/118157, filed on Sep. 14, 2021, which claims priority to Chinese Patent Application No. 202110304938.2, filed on Mar. 22, 2021, which is incorporated by reference for all purposes as if fully set forth herein. FIELD OF THE INVENTION The application relates to the technical field of air purification, and more particularly to a dust collecting mechanism, a car air purifier and a fan. DESCRIPTION OF THE RELATED ART With the increasing concern and requirements in life for air quality, it is more and more common to improve indoor/car air quality with air purifiers. An air purifier based on electrostatic dust collection technique includes an electrostatic filter element provided between an air inlet and an air outlet. The air enters the air purifier through the air inlet, passes through the electrostatic filter element, and then is discharged through the air outlet. The electrostatic filter element adsorbs pollutants in the air to purify the air. After the air purifier is used for a period of time, pollutants accumulate in the electrostatic filter element, so it is necessary to clean the electrostatic filter element regularly. The electrostatic filter element from prior art is generally integrated, and the emitting wire in the electrostatic filter element, the repelling piece and the collecting piece in the collecting block are integrated together, making it difficult to clean. SUMMARY OF THE INVENTION An object of the application to provide a dust collecting mechanism, a car air purifier and a fan that that can be easily cleaned. In a first aspect, an embodiment of the application provides a dust collecting mechanism including: a generator assembly including a generator holder, a generator plate and a generator filament, the generator plate and the generator filament being arranged in a spaced and staggered manner inside the generator holder; a collector assembly including a collector holder, a repeller plate and a collector plate, the repeller plate and the collector plate being arranged in a spaced and staggered manner inside the collector holder; wherein the generator holder is connected detachably with the collector holder, and the collector plate is connected and conducted with the generator filament through magnetic adsorption. In the above embodiment, the collector plate is connected and conducted with the generator filament through magnetic adsorption upon alignment, so that they can be connected to the power supply together, thereby enabling wireless conduction between the collector assembly and the generator assembly, simplifying the circuit structure, avoiding difficulty in detachment due to wired connection, and consequently facilitating assembly and disassembly between the collector assembly and the generator assembly, and the detached generator assembly would not cause disturbance in cleaning of the collector plate, making cleaning less difficult. In some embodiments, the collector plate and the generator filament are connected to a high-voltage power supply and the repeller plate and the generator plate are each grounded. In the above embodiments, among the collector plate and the generator filament, as a conducted unit, and also the repeller plate and the generator plate, only one of them is connected to the high-voltage power supply, thereby reducing the complexity of the circuit and difficulty in wiring and improving the safety performance.
