Carbon powder container

Abstract

The invention provides a carbon powder container. The carbon powder container comprises a container main body, an end cover, a driving piece, an annular gate piece, a guide rod, a protective cover and a cylindrical closed-ended positioning cover, wherein a through hole is formed in the bottom wall of the positioning cover in a penetration mode; a cylindrical part passes through the through hole; the positioning cover sleeves the end cover along the cylindrical part in a sling manner; a fixed part adjacent to the annular gate piece is arranged on a second end surface, close to the outer end of an opening, of the positioning cover; a first lock buckle part is further arranged on the positioning cover; a fixed column is arranged inwards on the bottom wall of the protective cover and is adjacent to the guide rod; the protective cover is provided with a second lock buckle part matched with the first lock buckle part. By virtue of fixed matching among the positioning cover, the protective cover and the annular gate piece, mechanical loss or elastic force attenuation is avoided, a powder outlet can be sealed even in the jolting transportation process, and the sealing property of the carbon powder container is improved favorably.

Description

technical field [0001] The invention relates to the field of electrophotographic imaging, in particular to a toner container for supplying toner to electrophotographic imaging equipment. Background technique [0002] An electrophotographic imaging device usually has an image processing unit and a developing unit, and uses developer such as toner provided by the developing unit to develop the electrostatic latent image formed on the image processing unit to form a visible image on paper and other media. Wherein, toner powder is used as a consumable item and needs to be constantly replenished into the electrophotographic imaging device. Generally, a toner container containing a certain amount of toner, which is detachably mounted to the developing unit in the electrophotographic imaging device, is used to supply the developing unit with toner. [0003] refer to figure 1 with figure 2 , figure 1 with figure 2 It is an exploded view and a sectional view of a carbon powder...

AI Technical Summary

Problems solved by technology

[0008] However, because the sealing of the ring gate 16 to the powder outlet 123 mainly depends on the biasing force of the spring 17, and when the toner container is used for a long time, it will inevitably affect the elastic recovery force of the spring 17, so the carbon powder is recovered. When the toner container is regenerated, the spring 17 needs to be replaced, and the replaced spring also needs to be of higher quality, which will inevitably increase the cost of recycling or producing the toner container

In addition, when the elastic recovery force of the spring 17 was weakened, when the toner container was extracted from the imaging device, the ring gate member 16 was prone to loose sealing of the powder outlet 123, and then the toner was easily leaked. Toner leakage can also occur in the imaging device, or during bumpy transportation, causing pollution to the environment
