Description

Technical Field

[0001] The utility model belongs to the technical field of processing boxes, and in particular relates to a waste toner bin supporting structure used for the processing box. Background Art

[0002] During the operation of the toner cartridge, after the toner cartridge's photosensitive drum undergoes a series of operations such as charging, exposure, and development, some toner cannot be completely transferred to the paper and becomes waste toner. The waste toner hopper is a container specifically designed to collect this waste toner. It is usually located on the side of the toner cartridge and is collected by components such as a cleaning scraper to prevent waste toner from scattering freely inside the toner cartridge, keeping the interior clean and avoiding any adverse effects on the normal operation of the cartridge and print quality. At the same time, a properly designed waste toner hopper also helps maintain the stability and effective operation of the toner circulation system within the toner cartridge. However, the waste toner hopper can deform in high temperature environments, when subjected to severe collisions, or when subjected to long-term unreasonable squeezing. Conventional technology is to add ribs to the inner wall of the waste toner hopper to strengthen the waste toner hopper frame and prevent deformation. However, if the processing cartridge is subjected to a severe collision or is exposed to high temperatures for a long time, the ribs may be damaged, causing the overall structure of the waste toner bin to become fragile and more prone to deformation during use, which may affect the normal operation of other parts of the toner cartridge. In the prior art, the support structure of the waste toner bin of the processing cartridge is usually composed of a single support plate or multiple support plates. This structure has the following problems: a single support plate cannot provide sufficient stability, which can easily cause the waste toner bin to deform; secondly, when multiple support plates are spliced ​​together, waste toner can easily accumulate in the gaps due to the presence of splicing gaps, affecting the normal flow of waste toner; finally, the existing support structure often cannot adapt well to the spatial layout inside the waste toner bin, resulting in low internal space utilization.

[0020] The embodiments of the present invention are described in detail below. Figures 1 to 4 , an embodiment of the present invention provides a waste toner bin support structure for a processing cartridge, comprising: a processing cartridge body 100 and a support structure 200, the processing cartridge body 100 comprising a waste toner bin 110 and a photosensitive drum 120, the photosensitive drum 120 being snapped onto the open end of the waste toner bin 110, the support structure 200 being located inside the waste toner bin 110, the support structure 200 comprising at least two intersecting support plates 230, the support plates 230 being provided with through holes 220 for guiding the flow of waste toner, the direction in which the axis of the photosensitive drum 120 extends being a first direction, the direction orthogonal to the first direction being a second direction, the length of the support structure 200 in the first direction being greater than the length in the second direction, the support plates 230 being aligned with the interior of the waste toner bin 110 The wall is fixed, and the stability of the support structure 200 is improved by setting at least two intersecting support plates 230, and the problem of deformation of the waste powder bin 110 due to uneven force is avoided. By setting the support plates 230 in an intersecting form, it can be flexibly adjusted according to the spatial layout inside the waste powder bin 110, thereby improving the utilization rate of the internal space of the waste powder bin 110. By setting through holes 220 on the support plates 230, the flow of waste powder can be effectively guided, and the accumulation of waste powder on the support plates 230 is avoided, thereby ensuring the normal flow of waste powder. By placing the support plates 230 in the waste powder bin 110, the stability of the support structure 200 is increased, and the support structure 200 is prevented from shifting or falling off during use.

[0021] Preferably, the two support plates 230 are made by an integral molding method. Since the integrally molded support plates 230 do not have welding or splicing points, the overall structural strength is higher and it is less likely to break or deform at stress concentration points, thereby enhancing the stability and durability of the support plates 230. It also reduces the additional parts and labor required in the assembly process, reducing manufacturing costs. Furthermore, the integrally molded support plates 230 can achieve lightweighting, which has a good effect on portable processing boxes. Of course, the present invention does not limit the specific connection method of the two support plates 230. Furthermore, the two support plates 230 are connected by a fixing member. Of course, the present invention does not limit the specific structure of the fixing member. Preferably, the fixing member can be a snap, adhesive buckle or screw. The two support plates 230 are connected together by mutually snapping, bonding or screwing. The connection by fixing member facilitates the assembly and disassembly of the support plates 230 and ensures the stability and functionality of the support plates 230. It is suitable for processing boxes that require regular maintenance or replacement.

[0022] Furthermore, refer to Figure 1 and Figure 2 , the photosensitive drum 120 rotates around its axis, the extending direction of the axis of the photosensitive drum 120 is called the first direction, and the direction orthogonal to the first direction is the second direction. Figure 3 and Figure 4 The waste powder bin 110 has a card slot 111 on its inner wall. The card slot 111 is used to fix the support plate 230. Both ends of the support plate 230 are provided with card stands 210. The card stands 210 can be connected to the card slot 111. Of course, the present invention does not limit the specific structure of the card slot 111 and the card stand 210. When the waste powder bin 110 is deformed in the second direction, the card stand 210 connected to the card slot 111 can effectively suppress the deformation of the waste powder bin 110 in the second direction. Further, referring to Figure 4, the support plate 230 is provided with through holes 220. Of course, the present invention does not limit the specific arrangement of the through holes 220. Preferably, the through holes 220 are in a regularly spaced array. The arrangement of the regularly spaced array can guide the waste powder to flow in a predetermined direction. Of course, the through holes 220 can also be arranged in a spiral pattern. In this way, the waste powder will flow along the spiral path, which helps to increase the contact area between the waste powder and the wall of the waste powder bin 110, and facilitates subsequent cleaning operations. Of course, the present invention does not limit the specific shape and material of the through hole 220. Preferably, the edge of the through hole 220 is provided with a smooth structure. When waste powder passes through, the smooth structure helps to remove the waste powder adhering to the edge of the through hole 220 and prevent the waste powder from accumulating near the through hole 220. Furthermore, the through hole 220 includes a first through hole 221 and a second through hole 222. The first through hole 221 and the second through hole 222 are located on different support plates 230. Preferably, the diameters of the first through hole 221 and the second through hole 222 are different. Through holes of different apertures can form a multi-stage filtration system, which is convenient for filtering waste powder of different particle sizes. Preferably, the aperture of the through hole 220 gradually decreases from the entrance to the outlet of the waste powder bin 110, which can control the flow rate of waste powder in different areas, optimize the distribution of waste powder, and reduce the risk of blockage.
