Description

Technical Field

[0001] The utility model relates to the technical field of copiers, in particular to a multiple powder adding developing bin. Background Art

[0002] The description of the background technology in the present utility model belongs to the related technology related to the present utility model, which is only used to illustrate and facilitate the understanding of the content of the present utility model, and should not be understood as the applicant explicitly believes or presumed that the applicant believes that it is the prior art of the present utility model on the filing date of the first application.

[0003] The copier needs to heat the toner when copying, and the toner needs to be continuously added during the process of continuous consumption. Currently, the copier adds toner to the developing chamber by using electromagnetic waves to sense the toner and determine the amount of toner. When the electromagnetic wave senses that the toner content in the developing chamber is too low, it will send out an electric frequency signal. After receiving the electric frequency signal, the copier mainboard will automatically add toner to the developing chamber.

[0004] The applicant has previously applied for a new detection system for the toner content of a copier, with the authorization announcement number: CN220418689U, in which a toner storage box includes multiple toner holding parts, each of which is connected to the copier developing bin through a powder delivery pipe. This requires multiple powder delivery pipes, which has obvious defects. There are many pipes and interfaces. When multiple powder delivery pipes are selected, the device will be cumbersome because the pipes occupy more space. Moreover, too many interfaces between the pipes and the developing bin will cause a high failure rate of the developing bin. Utility Model Content

[0005] The purpose of the embodiment of the utility model is to provide a multiple powder adding developing bin. By adopting a multi-layer containing bin, the interface with the tube is arranged at the bottom of the storage box.
