Description

Technical Field

[0001] The utility model relates to the technical field of selenium cartridges, in particular to a split-type selenium cartridge structure. Background Art

[0002] Compared with the integrated toner cartridge, the split toner cartridge adopts a detachable toner cartridge design. When the toner is exhausted, the user only needs to replace the toner cartridge, and the drum core can continue to be used until the end of its life. The design of the split toner cartridge allows users to replace parts separately according to actual usage, thereby reducing printing costs.

[0003] The toner cartridge body is usually equipped with a PCB chip that can store the collected information of the printer and is used to monitor the usage of the toner cartridge. If the PCB chip malfunctions and cannot normally feedback information to the printer, the toner cartridge may not be used normally after installation. The PCB chip is usually encapsulated on the side of the toner cartridge body, which is difficult for individual users to disassemble and replace. Usually, the entire toner cartridge body can only be replaced, resulting in high replacement costs. To this end, we propose a split toner cartridge structure to solve the above problem.

DETAILED DESCRIPTION

[0020] In order to further explain the technical solution of the present invention, specific embodiments are described in detail below.

[0021] See also Figure 1 The utility model provides a split toner cartridge structure, including a toner cartridge body 1, a toner cartridge 2, a drum core 3 and a chip mounting structure 4. The toner cartridge 2 is embedded in the inner rear part of the toner cartridge body 1, the drum core 3 is rotatably mounted on the inner front part of the toner cartridge body 1, and the chip mounting structure 4 is provided on the side of the toner cartridge body 1.

[0022] See also Figure 2-6 The present invention provides a split-type toner cartridge structure. The chip mounting structure 4 includes a mounting cavity 41, a docking groove 42, a buckle groove 43, a chip box 44, a docking portion 45, a fastener 46, a PCB chip 47, a chip contact 48 and a contact opening 49. The side wall of the toner cartridge body 1 is provided with a mounting cavity 41, a docking groove 42 is provided on the front side of the mounting cavity 41, a buckle groove 43 is provided on the rear side of the mounting cavity 41, and the chip box 44 is embedded in the inner side of the mounting cavity 41. The front side of the chip box 44 is integrally provided with a docking portion 45, and the rear side of the chip box 44 is connected with a fastener 46. The chip box 44 is first aligned with the mounting cavity 41. The connecting portion 45 is snapped into the inner side of the docking groove 42 and then snapped into the inner side of the snap groove 43 through the fastener 46, thereby realizing the snap-fit ​​installation of the chip box 44 and the installation cavity 41. A PCB chip 47 is encapsulated inside the chip box 44, and chip contacts 48 are provided on the surface of the PCB chip 47. The chip contacts 48 can contact with the printer contacts, thereby realizing the data connection between the PCB chip 47 and the printer. A contact opening 49 is provided on the surface of the chip box 44, and the contact opening 49 corresponds to the position of the chip contact 48, so that the chip contact 48 can make normal contact with the printer contact through the contact opening 49.

[0023] To further explain, the chip box 44 is made of anti-static material as a whole, and its material is any one of polyimide, polyamide, polycarbonate, ABS, organic glass, etc. Since the PCB chip 47 is sensitive to static electricity, the chip box 44 can protect the PCB chip 47 from the influence of electrostatic discharge and extend the service life of the PCB chip 47.

[0024] To further illustrate, the size of the contact opening 49 matches the size of the chip contact 48 to reduce the exposed area of ​​the PCB chip 47 and improve the protection effect.

[0025] To further illustrate, the chip box 44 has symmetrical clamping grooves 410 on the upper and lower sides of the side surface, the chip box 44 is covered with a protective cover 411, and the inner surface of the protective cover 411 has symmetrical clamping blocks 412 on the upper and lower sides. The clamping blocks 412 are embedded in the inner side of the clamping grooves 410, so that the protective cover 411 is clamped and fixed to the side surface of the chip box 44. When the chip box 44 is not installed, the protective cover 411 can cover the contact opening 49, thereby achieving a closed protection effect and preventing accidental damage to the chip contacts 48.

[0026] To further illustrate, the protective cover 411 is made of a non-transparent material so that the PCB chip 47 can be stored away from light.

[0027] Here’s how it works:

[0028] First, snap the toner cartridge 2 into the inner side of the toner cartridge body 1 to ensure the toner supply to the drum core 3.

[0029] Second, by setting a chip mounting structure 4 on the side of the toner cartridge body 1, when installing the PCB chip 47, first peel off the protective cover 411 from the surface of the chip box 44 to expose the contact opening 49, then first insert the docking portion 45 on one side of the chip box 44 into the inner side of the docking groove 42, and then snap the fastener 46 on the other side of the chip box 44 into the inner side of the buckle groove 43, so that the chip box 44 and the installation cavity 41 are snapped and installed, and the assembly of the PCB chip 47 and the toner cartridge body 1 can be completed. When the toner cartridge body 1 is installed into the working position inside the printer, the chip contact 48 contacts the printer contact, thereby realizing the data connection between the PCB chip 47 and the printer.

[0030] Third, when removing the PCB chip 47, first push the fastener 46 away from the inner side of the fastener groove 43, then flip the side of the chip box 44 with the fastener 46 out of the installation cavity 41, and finally move the chip box 44 until the docking portion 45 is disengaged from the inner side of the docking groove 42 to complete the removal of the PCB chip 47, which greatly reduces the difficulty of disassembly and installation of the PCB chip 47 and facilitates individual users to disassemble and replace it.

[0031] Fourth, when the chip box 44 is not installed, the protective cover 411 can be clipped onto the side surface of the chip box 44 to cover the contact opening 49, thereby achieving a closed protection effect and preventing accidental damage to the chip contacts 48.

[0032] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
