Abstract

The application provides a dust collecting mechanism, a car air purifier and a fan, and relates to the technical field of air purification. The dust collecting mechanism includes 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. The generator holder is detachably connected with the collector holder, and the collector plate is connected and conducted with the generator filament through magnetic adsorption, 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.

Claims (23)

1 . A dust collecting mechanism comprising:

a generator assembly including a generator holder,

a plurality of generator plates and a plurality of generator filaments, the plurality of generator plates and the plurality of generator filaments being arranged in a spaced and staggered manner inside the generator holder; the ends of the generator filament are connected respectively inside the generator holder, and the multiple generator filaments are distributed in parallel and spaced apart from each other inside the generator holder; and

a collector assembly including a collector holder, a plurality of repeller plates and a plurality of collector plates, the plurality of repeller plates and the plurality of collector plates 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 plurality of collector plates are connected electrically with the plurality of generator filaments thereby enabling wireless conduction between the collector assembly and the generator assembly, and each individual collector plate of the plurality of collector plates and each individual generator filament of the plurality of generator filaments contact with one another in one-to-one correspondence pressed against each other;

wherein the plurality of collector plates and the plurality of generator filaments are connected to a high-voltage power supply to enable wireless connection (electrically connected without wires) between the collector assembly and the generator assembly, and the plurality of repeller plates and the plurality of generator plates are each grounded;

wherein the collector holder is provided with a first magnetic adsorption contact, a second magnetic adsorption contact, and a third magnetic adsorption contact, and the first, second and third magnetic adsorption contacts are facing away from the generator holder to facilitate connection to the high-voltage power supply;

wherein the plurality of collector plates and the plurality of generator filaments are connected to the high-voltage power supply via the first magnetic adsorption contact;

wherein the plurality of repeller plates are grounded via the second magnetic adsorption contact; and

wherein the plurality of generator plates and the collector holder are connected and conducted wirelessly so as to be grounded via the third magnetic adsorption contact.

2 . The dust collecting mechanism of claim 1 , wherein a handle is provided on the side of the generator holder facing away from the collector holder.

3 . The dust collecting mechanism of claim 1 , wherein a spacing between the plurality of collector plates and the plurality of repeller plates is 1-2 mm.

4 . The dust collecting mechanism of claim 1 , wherein the generator holder is in threaded connection with the collector holder; or

the generator holder is provided with a first clamping piece and the collector holder is provided with a second clamping piece, and the first clamping piece and the second clamping piece cooperate with each other such that the generator holder is detachably connected to the collector holder.

5 . A car air purifier, comprising the dust collecting mechanism of claim 1 .

6 . The car air purifier of claim 5 , further comprising:

a support base provided in the interior space of the car;

a mounting base provided on the support base, the dust collecting mechanism being provided on the mounting base;

an air inlet provided on the mounting base and close to the generator assembly of the dust collecting mechanism;

an air outlet provided on the mounting base and close to the collector assembly of the dust collecting mechanism; and

a blower provided at the air inlet and/or the air outlet to provide negative pressure.

7 . The car air purifier of claim 6 , wherein the mounting base is rotatably provided on the support base for adjusting the mounting base so that a preset included angle is maintained between the mounting base and the horizontal plane.

8 . A fan, comprising the dust collecting mechanism of claim 1 .
