Abstract
The invention relates to the field of office consumables, and relates to a carbon powder cartridge with a permanent magnet, which is applicable to laser printers and comprises a powder bin and a cartridge body of a developing device; a sensitometric drum in the cartridge body is protected by a protective cover. a permanent magnet is disposed at an arm side of the protective cover, and the permanent magnet and a permanent magnet at a corresponding position on a surface of a waste powder bin attract each other so as to provide reposition power for the protective cover; in addition, the invention has the advantages of beautiful appearance, easy dismounting, recycling and saving, long service life, and the like.
Description
Technical field
The consumptive material field that the present invention relates to handle official business is a kind of cartridge with permanent magnet that is used for laser printer.
Background technology
The employed cartridge of laser printer is after being installed to printer, and protective cover is in naked state because of the screens on the printer is opened it with photosensitive drums, so that printer normally can develop, print to after the transfer printing on the print media and accomplish print procedure.When cartridge was not installed on the printer, protective cover then was in closure state to play the effect of protection photosensitive drums.Because be in open configuration for a long time, torsion spring can more be in deformed state, and follow-up reset effect can reduce than the initial reset effect greatly, and can't continue the complete preservation photosensitive drums influences printing effect.
The reset generator of power of above-mentioned protective cover is the torsion spring that is positioned on the protective cover turning axle.Torsion spring generation deformation when protective cover leaves protective position, protective cover can not automatically reset to protective position under the twisting force that torsion spring deformation provides.By torsion spring the cartridge of the power that resets is provided, torsion spring can make its torsion diminish because of deformation in processes such as use, transportation, and protective cover resets and is short of power.
Summary of the invention
A kind of cartridge purpose with permanent magnet is to design a kind of cartridge that uses permanent magnet that the power that resets of protective cover is provided, and has solved to adopt torsion spring to provide the torsion mode to cause deficiencies such as protective cover distortion.
To achieve these goals, technical scheme of the present invention is: arm one side of protective cover is provided with a permanent magnet, thereby the permanent magnet of this permanent magnet and waste powder hopper surface correspondence position attracts each other and the power that resets is provided for protective cover.
A kind of cartridge with permanent magnet comprises the box body of a powder storehouse and a developing apparatus.The Outboard Sections that is positioned at photosensitive drums at cartridge is provided with protective cover, and the spy is provided with a permanent magnet in protective cover arm one side, is convenient to protective cover and better resets, and has reached the purpose of better protection photosensitive drums.On the waste powder hopper with protective cover on the corresponding position of permanent magnet be provided with a permanent magnet equally.On the protective cover on permanent magnet and the waste powder hopper permanent magnet protective cover reset after the position attract each other and fit like a glove.Thereby the permanent magnet of above-mentioned permanent magnet and waste powder hopper surface correspondence position attracts each other to protective cover provides rotational power, to abolish fundamentally that traditional torsion spring provides power and defective that deformation takes place.
A kind of cartridge with permanent magnet provided by the invention has advantages such as appearance looks elegant, easy disassembling, cycle saving, life-span be permanent.

Embodiment
A kind of cartridge with permanent magnet comprises the box body of a powder storehouse and a developing apparatus.The Outboard Sections that is positioned at photosensitive drums at cartridge is provided with protective cover, and the spy is provided with a permanent magnet in protective cover arm one side.On the waste powder hopper with protective cover on the corresponding position of permanent magnet be provided with a permanent magnet equally.On the protective cover on permanent magnet and the waste powder hopper permanent magnet protective cover reset after the position attract each other and fit like a glove.
