Embodiment Construction
[0020] Such as figure 2 A powder box shown includes: a powder cylinder 1 that can accommodate carbon powder; a stirring frame 2 installed in the powder cylinder 1; a driving gear 11 of the stirring frame 2; and a first powder feeding element 3 and a powder box. The second powder feeding element 4, they deliver the carbon powder to the first powder outlet 6; there is a sliding element 5 near the first powder outlet 6, the sliding element 5 is hollow, and can slide back and forth on the powder cartridge 1, The first powder outlet 6 can be sealed or connected; the first magnetic element 7 is fixed on the front end of the powder cartridge 1; the second magnetic element 8 is fixed on the front end of the sliding element 5 close to the first magnetic element 7, They are two opposite magnets that attract each other.
[0021] Such as image 3 As shown, the sliding element 5 is pasted with a sealing material 10, such as sponge, felt, etc., which seals the first powder outlet 6 and p...

The invention discloses a powder box for an electro photography imaging device, comprising a powder barrel holding the carbon powder and provided with a powder outlet, a sliding element sliding freely in the powder barrel and a sliding element holding mechanism asking the sliding element to close the powder outlet under in the non-use state. The sliding element holding mechanism includes a first magnetic element arranged on the powder barrel and a second magnetic element arranged on the sliding element to generate a mutual magnetic force action with the first magnetic element. Compared with the sliding element holding mechanism using the elastic element, the shell is unnecessary to be arranged at one end of the powder barrel, thereby the powder box structure is simpler and the material is saved. Additionally, the manufacture is simpler and the manufacture difficulty is reduced owing to no strict requirement to the magnetic element in size.
Description
technical field [0001] The invention relates to a powder box for an electrophotographic imaging device. Background technique [0002] Common electrophotographic imaging devices, such as laser printers, copiers, etc., include: scanning devices, developing devices, transfer devices and fixing devices. Wherein, the developing device also includes: a photosensitive drum on which an electrostatic latent image is formed; a developing roller for developing the electrostatic latent image on the photosensitive drum; a charging roller for charging the surface of the photosensitive drum; Toner Roller; a toner cartridge that supplies toner for the development process. [0003] For an electrophotographic imaging device, the used carbon powder is a consumable material, and the toner cartridge with a certain capacity must be replaced with a new toner cartridge after use. [0004] Korean Patent Publication No. KR1020070021848A, published on February 23, 2007, discloses a powder outlet str...
