Problems solved by technology
[0003] In the existing image forming device, the toner is usually placed in the toner drum or ink cartridge of the image forming device. If the user wants to know the remaining amount of toner, he needs to take out the toner cartridge or ink cartridge from the printer to check, which is very inconvenient
Moreover, when the user prints through the image forming device, he often encounters the situation that the printing is suspended due to insufficient toner, and he can only temporarily find the toner to add, which wastes the user's time and even delays the user's printing progress and causes huge losses.
[0004] In particular, the existing toner box powder detection schemes include optical powder detection, capacitive powder detection, and ultrasonic powder detection, which are relatively expensive or have complex structures. There is also a type of magnetic signal powder detection that is only suitable for magnetic toner detection. , there is also a way to detect insufficient toner by measuring the current of the SR (supply roller), but the disadvantage of this solution is that when the toner is detected to be insufficient, the image has defects, and the user cannot be reminded in advance

Embodiment Construction
[0047] In order to better understand the technical solutions of the present invention, the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.
[0048] It should be clear that the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0049]In this application, "at least one" means one or more, and "multiple" means two or more. "And / or" describes the association relationship of associated objects, indicating that there may be three types of relationships, for example, A and / or B, which can mean: A exists alone, A and B exist simultaneously, and B exists alone, where A, B can be singular or plural. The character " / " generally indicates that the contextual objects...

The embodiment of the invention provides a powder box, a method for detecting the residual amount of carbon powder and an image forming device. The powder box is installed on the image forming device,and comprises a powder bin used for containing the carbon powder; a stirring unit which is arranged in the powder bin and is used for stirring the carbon powder in the powder bin; and a detection unit which is arranged on the stirring unit and is used for making contact with the carbon powder in the carbon powder stirring process of the stirring unit and outputting a current signal. According tothe scheme, whether the powder box is lack of powder or not can be determined before printed images have defects due to powder lack, meanwhile, the detection process is more convenient, and the detection cost is lower.
Description
technical field [0001] The present application relates to the technical field of image formation, and in particular to a powder box, a method for detecting remaining amount of toner, and an image forming device. Background technique [0002] Image forming devices are indispensable office equipment in daily work and study. Toner is an indispensable material for laser printers to complete printing smoothly. [0003] In the existing image forming device, toner is usually placed in the toner drum or ink cartridge of the image forming device, and the user needs to take out the toner drum or ink cartridge from the printer to check the remaining amount of toner, which is very inconvenient. Moreover, when the user prints through the image forming device, he often encounters the situation that the printing is suspended due to insufficient toner, and he can only temporarily find the toner to add, which wastes the user's time and even delays the user's printing progress and causes hug...
