AI Technical Summary
During the use of the toner cartridge, due to the limited space of the waste powder bin, the waste powder is unevenly distributed when printing A5 large and small paper, resulting in the cleaning scraper losing its cleaning function and affecting the printing effect.
Use inclined ribs with multiple guide holes as powder guide plates, which are integrated with the cleaning scraper and waste powder bin. The guide holes are arranged from the bottom to the top, with 3 layers of each layer to ensure that the waste powder is evenly distributed and avoid accumulation. .
Through the design of the guide holes, the waste powder is evenly distributed, which reduces the probability of the waste powder warehouse being full, maintains the function of the cleaning blade, and improves the printing effect.

Abstract
Description
Technical Field
[0001] The invention discloses a toner cartridge capable of preventing waste powder from accumulating, and relates to the technical field of laser printers, in particular to a toner cartridge. Background Art
[0002] Among the toner cartridges currently on the market, the waste toner bin of the toner cartridge is relatively small due to the limitation of the overall size. During actual use of the toner cartridge, especially when printing A5-sized paper, since there is no imaging on both sides of the photosensitive drum, all the toner on the photosensitive drum is converted into waste toner and enters the waste toner bin. Therefore, during actual use, the waste toner on both sides of the waste toner bin will be more than the waste toner in the middle, instead of being evenly distributed in the waste toner bin. When too much waste toner accumulates in the two sides, the subsequent waste toner cannot enter the waste toner bin and accumulates on the blade of the cleaning scraper, thereby causing the cleaning scraper to lose its cleaning function, resulting in abnormal printing effect of the toner cartridge. Summary of the invention
[0003] In view of the above-mentioned deficiencies in the prior art, the present invention provides a toner cartridge that prevents waste toner from accumulating, so that waste toner will not accumulate at a certain position of the waste toner bin during use of the toner cartridge.
[0004] The present invention adopts the following technical scheme: a toner cartridge for preventing waste powder accumulation, comprising a waste powder bin, a photosensitive drum, a cleaning scraper and a powder guide plate; the photosensitive drum and the cleaning scraper are installed in parallel on the waste powder bin, and the closed space surrounded by the photosensitive drum, the cleaning scraper and the waste powder bin is used to store waste powder; the powder guide plate is an oblique rib plate with a plurality of drainage holes, the drainage holes are arranged in 3 layers from bottom to top, each layer has 3 drainage holes, the drainage holes of the upper and lower layers are semicircular, the middle drainage hole is circular, and the diameter of the drainage hole depends on the height of the waste powder bin; the powder guide plate is integrated with the waste powder bin by injection molding, and is located on the waste powder bin below the cleaning scraper after it is installed in place, with one on each side, and the bottom and two ends are connected to the waste powder bin, and the powder guide plate is perpendicular to the plane of the cleaning scraper when viewed from a horizontal perspective, and there is an angle between the powder guide plate and the blade of the cleaning scraper when looking down from the cleaning scraper.
[0005] When printing A5 size manuscripts, there is more waste toner on both sides. When entering the waste toner bin, since the surface of the powder guide plate has multiple drainage holes and there is an angle with the blade of the cleaning scraper, part of the waste toner enters the lower part of the powder guide plate through the drainage holes of the powder guide plate, and the other waste toner moves along the powder guide plate to the middle area of the waste toner bin; with many drainage holes, the waste toner accumulated in the middle area and on both sides of the powder guide plate will be more balanced. Even if more waste toner enters on one side, under the action of the drainage holes, the waste toner on the side with more waste toner will still enter the other side with less waste toner through the drainage holes, making it difficult for the waste toner on both sides of the waste toner bin to accumulate and burst; the same principle applies to printing other manuscripts.
[0006] The beneficial effects of the present invention are: the waste powder is evenly distributed and the probability of waste powder explosion is reduced. BRIEF DESCRIPTION OF THE DRAWINGS
[0007] Attached Figure 1 1 is a top view of a waste toner bin of a toner cartridge for preventing waste toner from accumulating. Figure 2 It is an oblique view of a waste toner bin of a toner cartridge for preventing waste toner from accumulating according to the present invention, Figure 3 The present invention is a schematic diagram of a powder guide plate of a waste powder bin of a toner cartridge for preventing waste powder from accumulating. In the figure: 1 is the waste powder bin, 2 is the powder guide plate, and 3 is the drainage hole. Implementation
[0008] The present invention will be specifically described below in conjunction with the accompanying drawings: Figure 1 , Figure 2 and Figure 3 The invention discloses a toner cartridge for preventing waste powder from accumulating, comprising a waste powder bin 1, a photosensitive drum, a cleaning scraper and a powder guide plate 2; the photosensitive drum and the cleaning scraper are parallelly mounted on the waste powder bin 1, and a closed space surrounded by the photosensitive drum, the cleaning scraper and the waste powder bin 1 is used to store waste powder; the powder guide plate 2 is an oblique rib plate with a plurality of dredging holes 3, the dredging holes 3 are arranged in 3 layers from bottom to top, each layer has 3 dredging holes 3, the dredging holes 3 of the upper and lower layers are semicircular, the dredging holes 3 in the middle are circular, and the diameter of the dredging holes 3 depends on the height of the waste powder bin 1; the powder guide plate 2 is integrated with the waste powder bin 1 by injection molding, and is located on the waste powder bin 1 below the cleaning scraper after it is installed in place, with one on each side, and the bottom and two ends are connected to the waste powder bin 1, and the powder guide plate 2 is perpendicular to the plane of the cleaning scraper when viewed from a horizontal perspective, and there is an angle between the powder guide plate 2 and the blade of the cleaning scraper when viewed from the cleaning scraper. When printing A5 size manuscripts, there is more waste powder on both sides. When entering the waste powder bin 1, since the surface of the powder guide plate 2 has multiple drainage holes 3 and there is an angle with the blade of the cleaning scraper, part of the waste powder enters the lower part of the powder guide plate 2 through the drainage holes 3 of the powder guide plate 2, and the other waste powder moves along the powder guide plate 2 to the middle area of the waste powder bin 1; there are many drainage holes 3, so that the waste powder accumulated in the middle area and on both sides of the powder guide plate 2 will be more balanced. Even if more waste powder enters one side, under the action of the drainage holes 3, the waste powder on the side with more waste powder will still enter the other side with less waste powder through the drainage holes, so that the waste powder on both sides of the waste powder bin 1 is not easy to accumulate and burst; and the same principle applies to printing other manuscripts. The beneficial effect of the present invention is: the waste powder is evenly distributed and the probability of waste powder bursting is reduced.
