Specific embodiment
Below according to description of the drawings embodiment.
As shown in Figure 1, 2, the charging unit of the prior art includes corona wire 1, aperture plate 2, photosensitive drums 3 and shell 4.Using
The charging unit of the prior art, corona wire 1, aperture plate 2 form voltage difference, and ionized by way of electric discharge after distinguishing receiving voltage
Air, to form ion.Upper-center position of the corona wire of the prior art due to being arranged on aperture plate, in corona wire and grid
During net electric discharge, only between some in aperture plate or certain multiple netted electric wire electrical communication occurs for corona wire, because
There is the non-uniform phenomenon that charges in this photosensitive drums 3.
In order to solve the above technical problems, the present invention provides a kind of charging units.
As in Figure 3-5, charging unit includes corona wire 10, aperture plate 20 and shell 40；The corona wire 10 is provided with more
It is a and be evenly distributed, electric discharge protrusion 101 is additionally provided on corona wire 10, electric discharge protrusion 101 is evenly provided on corona wire.
Multiple aperture plate electric wires 201 are provided on aperture plate 20 and are uniformly distributed, is provided on the aperture plate electric wire 201 and connects electric protrusion 202, and
Electric protrusion 202 is connect to be evenly distributed on aperture plate electric wire 201.As shown in Figure 3,4, the electric discharge protrusion 101 and aperture plate on corona wire
The electric protrusion 202 that connects on electric wire 201 corresponds on paper；Corona wire 10 on the direction perpendicular to paper with aperture plate electric wire
201 correspond；Such arrangement can make the charge and discharge process of charging unit more uniform, and charge and discharge effect is more preferable.
As shown in Figure 4,5, when the electric discharge protrusion 101 on corona wire 10 on aperture plate electric wire 201 with connecing electric protrusion 202 one by one
After correspondence, electric discharge protrusion 101 with connect and be electrically connected between electric protrusion 202 after, charge 5 is obtained by ionized air, due to discharging
Protrusion 101 and the uniform arrangement for connecing electric protrusion 202, therefore uniformly arrangement is also presented in charge 5 between corona wire 10 and aperture plate 20,
Therefore when charge 5 is by electric field driven to photosensitive drums 30, charge 5 is evenly spaced in 30 surface of photosensitive drums, so as to make photosensitive drums
30 surface charging is uniform.
Above-described embodiment is intended merely to the purposes of the interpretation present invention, and is not limitation of the present invention, this technology
The technical staff in field in the essential scope of the present invention, makes a variety of changes or substitutes, and should also belong to the protection model of the present invention
Farmland.
