Description

Technical Field

[0001] The utility model relates to the technical field of carbon powder boxes, in particular to a carbon powder box which is convenient for adding carbon powder. Background Art

[0002] Toner cartridges are important components in laser printers. Current printer consumables can be roughly divided into three categories: ribbons, inkjet and laser. For a toner cartridge, some of the following parts are consumed quickly and need to be replaced or replenished frequently, such as the photosensitive drum, toner, magnetic roller, charging roller, cleaning blade and powder discharge knife. These are the typical six consumable parts, usually called the six major consumable parts.

[0003] Existing toner cartridges usually use a closed switch to seal the toner adding port. The sealing effect of a single closed switch is poor, and toner is easy to leak. In addition, the existing toner cartridges are not easy to disassemble and clean. The residual toner inside is not properly removed due to moisture, which also affects the printing quality, bringing certain adverse effects to people's use process. In order to solve the shortcomings of the existing technology, we propose a toner cartridge that is easy to add toner. Utility Model Content

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] Example 1, as Figures 1-4 As shown, a toner cartridge convenient for adding toner includes a toner cartridge body 1, a toner storage box 2 detachably mounted on one end of the toner cartridge body 1, a detachably mounted limit frame 4 surrounding the inner wall of the toner storage box 2, support columns 5 detachably mounted on the four corners of the inner wall of the toner storage box 2, a sealing cover plate 6 slidably connected to the inside of the toner storage box 2, and a movable cover plate 13 on the sealing cover plate 6 is tightly closed by the elastic force of the metal spring 14 itself to form a through hole opened by the sealing cover plate 6. The first sealing protection of the through hole, the rubber card block 11 serves as the second sealing protection of the through hole opened by the sealing cover plate 6, and the rubber card block 11 drives the fixed block 12 to be clamped in the card groove opened by the movable cover plate 13 to prevent the movable cover plate 13 from loosening, thereby improving the overall sealing effect. When adding carbon powder, it is only necessary to deduct the rubber card block 11 to drive the fixed block 12, and then push the movable cover plate 13 to no longer block the through hole opened by the sealing cover plate 6, so that carbon powder can be added conveniently. After use, the double seal ensures that the internal carbon powder does not leak.

[0022] Example 2, as Figure 2 and Figure 3As shown, a toner cartridge that is convenient for adding toner powder utilizes a limit block 9 to limit the position, and at this time, the sealing strip 7 is tightly pressed against the sealing cover plate 6 on the limit frame 4 and the support column 5, thereby enhancing the internal sealing, reducing the risk of internal toner getting damp, making it convenient for staff to use, reducing the waste of toner, and saving the cost of use. When it is necessary to clean the residual toner inside, the sealing cover plate 6 can be opened by rotating the limit block 9. The installation structure is simple, which is convenient for staff to quickly disassemble and clean the residual toner inside, and is not easy to contaminate the new toner added subsequently.

[0023] It should be noted that the present invention is a toner cartridge that is convenient for adding toner. When in use, the rubber card block 11 is lifted up in the through hole opened in the sealing cover plate 6. The rubber card block 11 stretches the rubber column 10 inside the through hole opened in the sealing cover plate 6. The rubber card block 11 opens on the sealing cover plate 6. At the same time, the sealing cover plate 6 drives the fixed block 12 to disengage from the card slot opened in the movable cover plate 13. The fixed block 12 no longer limits the movable cover plate 13, and then pushes the movable cover plate 13 to compress the metal spring 14. The movable cover plate 13 retreats into the sliding groove opened in the sealing cover plate 6, thereby no longer blocking the through hole opened in the sealing cover plate 6. Toner is injected into the toner storage box 2 through the through hole opened in the sealing cover plate 6, thereby achieving the purpose of conveniently adding toner.

[0024] After injecting toner into the toner storage box 2 and using it for a period of time, the limit block 9 is pushed to rotate on the fixed shaft 8, and the limit block 9 exits the limit groove opened by the toner storage box 2, and the limit block 9 completely enters the storage groove opened by the sealing cover 6, so that the limit block 9 no longer limits the sealing cover 6, and the sealing cover 6 is taken out from the toner storage box 2, and then the residual toner in the toner storage box 2 is cleaned, and then the rubber cover 3 is pulled to open the toner storage box 2, and the residual toner in the toner cartridge body 1 connected to the toner storage box 2 is removed. The remaining toner is poured out and the residual toner inside the toner cartridge body 1 and the toner storage box 2 is cleaned. After cleaning, the sealing cover 6 is put back in place, and then the sealing cover 6 is pressed. The sealing cover 6 drives the sealing strip 7 to be pressed tightly on the support column 5 and the limit frame 4, and then the limit block 9 is pushed to rotate on the fixed shaft 8. The limit block 9 is transferred from the storage groove opened by the sealing cover 6 to the limit groove opened by the toner storage box 2, completing the installation of the sealing cover 6, and realizing the purpose of convenient disassembly and assembly of the sealing cover 6 to clean the inside of the toner storage box 2.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
