Description

Technical Field

[0001] The present invention relates to the technical field of printer toner cartridges, and specifically provides a horizontal push-in in-position detection device. Background Art

[0002] A toner cartridge, also known as a photosensitive drum, generally consists of a basic substrate made of aluminum and a photosensitive material coated on the substrate; in a laser printer, more than 70% of the imaging components are concentrated in the toner cartridge. Currently, after a certain amount of printing powder in the printer toner cartridge is consumed, it is necessary to connect a powder cartridge to add printing powder to the toner cartridge so that the toner cartridge can be used again.

[0003] Currently, the in-position detection method for the ID CHIP of printer toner cartridges or ink cartridges on the market is to achieve device recognition by contacting the in-position chip through a shrapnel or a spring. The usual placement method is for the spring or shrapnel to move towards the chip's gold fingers for contact. Generally, it is pushed in vertically or contacted from top to bottom, and the spring or shrapnel is basically facing the gold fingers.

[0004] For example, the utility model patent with the application number CN202222981837.1 discloses a toner cartridge inspection structure, including a toner cartridge body and a powder cartridge body. The powder cartridge body is arranged in the inner cavity of the toner cartridge body. A shell is arranged on the left side of the inner cavity of the toner cartridge body. An activity groove is opened in the inner cavity of the shell. Fixing mechanisms are arranged at the top and bottom of the inner cavity of the activity groove. A fixing groove for cooperating with the fixing mechanism is opened on one side of the powder cartridge body close to the shell. Through the combined use of the fixing mechanism, the fixing groove and the control mechanism in this utility model, when pulling the pull block, while the pull block drives the connecting block to slide on the surface of the positioning column, the connecting block drives the fixing block into the inner cavity of the activity groove through the sliding rod and compresses the spring, solving the problem that the existing toner cartridge and powder cartridge are not convenient for inspection. When detecting the toner cartridge, some toner cartridges and powder cartridges are connected and fixed by screws. During inspection, it is not convenient to disassemble, and the screws are prone to thread slipping after multiple disassembly and assembly, affecting the fixing effect. However, the toner cartridge inspection structure provided by this utility model patent still has the problem that the in-position detection of the ID CHIP of the powder cartridge by the toner cartridge device cannot be achieved. Just by compressing the spring, it cannot be confirmed whether the powder cartridge is installed in the appropriate position and whether normal printing work can be carried out.

[0005] Based on the above problems, the present invention proposes a horizontal push-in in-position detection device. Summary of the Invention

[0058] The design principle of the present invention is as follows: By providing a drum device 3, a conductive pressing device 1 and a powder cartridge device 2, the conductive pressing device 1 includes a pressing head 11. During operation, the powder cartridge device 2 is pushed into the powder bin slot 31 of the drum device 3 by pushing the handle 22.
