DETAILED DESCRIPTION

[0027] The embodiments of the present utility model are described in detail below:

[0028] Embodiment 1

[0029] Reference Figure 1 The first embodiment of the present invention provides a developing box and a waste powder storage device thereof. Figure 1 Schematic diagram of the structure of the developing box in the first embodiment of the utility model. Figure 2 for Figure 1 A cross-sectional view of the developing box along a first direction, Figure 3 It is a schematic structural diagram of the waste powder storage device in the first embodiment of the present utility model.

[0030] like Figure 1 and Figure 2As shown in FIG. 1 , the waste toner storage device is disposed in the developing box, and the waste toner storage device includes a housing 100, a waste toner conveying plate 200, and a power receiving component 300 connected to the waste toner conveying plate 200. A waste toner bin 110 is provided inside the housing 100. Figure 2 and Figure 3 As shown, the housing 100 includes a bottom cover 130 and a front cover 140, and the waste powder bin 110 includes a waste powder storage bin 112 and a waste powder inlet bin 111 distributed along a first direction and connected to each other. A powder guide structure 120 is provided on the side wall of the waste powder bin 110, and the powder guide structure 120 is connected to the inner side wall of the bottom cover 130, and the powder guide structure 120 extends along the first direction. The waste powder conveying plate 200 is arranged in the waste powder bin 110 and is arranged opposite to the powder guide structure 120. The first end of the waste powder conveying plate 200 is located in the waste powder storage bin 112 and connected to the power receiving component 300, and the second end of the waste powder conveying plate 200 is located in the waste powder inlet bin 111. The power receiving component 300 is arranged at the end of the shell 100, and can receive the driving force from the imaging device and drive the waste powder conveying plate 200 to move. When the waste powder conveying plate 200 moves, its second end will move in the waste powder entry bin 111, thereby stirring the waste powder entry bin 111 and the waste powder at the bin mouth, and combined with the guiding effect of the powder guide structure 120, the waste powder can be conveyed along the first direction to the inside of the waste powder bin 110, avoiding the accumulation of waste powder at the bin mouth of the waste powder bin 110, thereby ensuring the normal progress of printing work and ensuring the printing effect.

[0031] In this embodiment, the first direction refers to the direction from the waste powder inlet bin 111 to the waste powder storage bin 112. Of course, it should be noted that the first direction is not necessarily parallel to the width direction of the developer box, as long as it is the direction from the waste powder inlet bin 111 to the waste powder storage bin 112. That is, the first direction is approximately the width direction of the developer box, but it can have a certain angle deviation from the width direction of the developer box. Therefore, the extension direction of the powder guide structure 120 is along the width direction of the developer box in the general direction, but the structure inside the powder guide structure 120 can extend in other directions.

[0032] For example, refer to Figure 4 In this embodiment, the powder guiding structure 120 includes a plurality of powder guiding ribs 121 distributed along the second direction. When the waste powder conveying plate 200 is displaced and the waste powder at the bin opening is stirred, the waste powder can enter the waste powder storage bin 112 more smoothly along the powder guiding ribs 121. Similarly, the second direction is not necessarily parallel to the length direction of the developing cartridge, that is, the second direction is approximately the length direction of the developing cartridge, but may have a certain angle deviation from the length direction of the developing cartridge.

[0033] Further, the powder guide rib 121 includes a main rib 1211 and a branch rib 1212 connected to the side of the main rib 1211, and the branch rib 1212 extends along a first direction toward a direction away from the main rib 1211, so as to prevent the waste powder entering the waste powder storage bin 112 from flowing back, so that the waste powder remains in the waste powder storage bin 112. Further, a plurality of branch ribs 1212 are provided, and the plurality of branch ribs 1212 are distributed along both sides of the main rib 1211, and the branch ribs 1212 located on both sides of the main rib 1211 are staggered, which can further improve the effect of preventing backflow.

[0034] Embodiment 2

[0035] Reference Figure 5 , the second embodiment of the present utility model provides a waste powder storage device, which is different from the waste powder storage device in the first embodiment in that: there are two groups of powder guide ribs 121 distributed along the second direction, the two groups of powder guide ribs 121 are approximately symmetrically distributed, and the powder guide ribs 121 extend along the first direction toward the middle of the shell 100. When the waste powder conveying plate 200 is displaced, the waste powder can smoothly enter the waste powder storage bin 112 along the powder guide ribs 121, and the powder guide ribs 121 extend along the first direction toward the middle of the shell 100, so a certain arc is formed, which can also prevent the waste powder in the waste powder storage bin 112 from flowing back. Of course, it should be noted that the second direction has no distinction between positive and negative directions, but the first direction specifically refers to the direction from the waste powder entry bin 111 to the waste powder storage bin 112, and the direction from the waste powder storage bin 112 to the waste powder entry bin 111 is the opposite direction of the first direction.

[0036] Embodiment 3

[0037] The third embodiment of the present invention provides a waste toner storage device, which is different from the waste toner storage device in the first embodiment in that: the present embodiment provides a connection and transmission structure between a power receiving component 300 and a waste toner conveying plate 200. Figure 6 and Figure 7 , a long strip-shaped connecting hole 210 is provided at the first end of the waste powder conveying plate 200; the power receiving component 300 is a gear, and a transmission shaft 400 is fixedly connected to the gear. A protrusion 410 is provided on the side of the transmission shaft 400, and the transmission shaft 400 is inserted into the connecting hole 210, and the protrusion 410 abuts against the side wall of the connecting hole 210; when the gear drives the transmission shaft 400 to rotate, the protrusion 410 slides along the side wall of the connecting hole 210, and when the protrusion 410 abuts against different side walls of the connecting hole 210, it can drive the waste powder conveying plate 200 to move back and forth continuously. Every time the protrusion 410 rotates one circle, the waste powder conveying plate 200 completes a reciprocating motion, thereby forming agitation at the waste powder entry bin 111, so that the waste powder in the waste powder entry bin 111 can enter the waste powder storage bin 112 more smoothly.

[0038] Embodiment 4

[0039] The fourth embodiment of the present invention provides a waste toner storage device, which is different from the waste toner storage device in the first embodiment in that: the present embodiment provides a connection and transmission structure between a power receiving component 300 and a waste toner conveying plate 200. Figure 8 and Fig. 9 , an annular groove 141 is provided in the housing 100, and the annular groove 141 is provided on the inner side of the cover 140, and the power receiving component 300 is a gear; the waste powder conveying plate 200 has a connecting shaft 500, and the connecting shaft 500 and the waste powder conveying plate 200 are integrally formed. The first end of the connecting shaft 500 is rotatably connected to the gear, and the connecting point between the connecting shaft 500 and the gear deviates from the rotation center of the gear. It should be noted that the connecting point between the connecting shaft 500 and the gear mentioned here is not necessarily located on the gear. When the connecting shaft 500 is directly connected to the gear, the connecting point is located on the gear, but when the gear is connected to the connecting shaft 500 through other structures, the connecting point is located on other structures. At this time, the projection of the connecting point on the gear deviates from the rotation center of the gear. The second end of the connecting shaft 500 is movably inserted into the annular groove 141; when the gear rotates, it can drive the second end of the connecting shaft 500 to slide along the annular groove 141, and when the waste powder conveying plate 200 abuts against the shell 100, the connecting shaft 500 can rotate relative to the gear. Since the connecting shaft 500 is eccentrically connected to the gear, when the gear rotates, the connecting shaft 500 will rotate around the axis of the gear, thereby driving the second end of the waste powder conveying plate 200 to move, and the connecting shaft 500 and the gear are rotatably connected. Therefore, the second end of the waste powder conveying plate 200 only reciprocates within a small range and will not flip around the gear, so that there will be no motion interference with the shell 100. When the connecting shaft 500 is directly connected to the gear, a hole can be opened in the gear that deviates from its rotation center, and the first end of the connecting shaft 500 can be rotatably inserted into the hole. The gear can also be connected to the connecting shaft 500 through other structures. For example, refer to Figure 8 An eccentric wheel 600 is coaxially connected to the gear, and the first end of the connecting shaft 500 is rotatably connected to the eccentric wheel 600.

[0040] Embodiment 5

[0041] The fifth embodiment of the utility model provides a waste powder storage device, which is different from the waste powder storage device in the fourth embodiment in that: this embodiment provides another connection and transmission structure between the power receiving component 300 and the waste powder conveying plate 200. In this embodiment, the connecting shaft 500 is a non-linear shaft, and the connecting shaft 500 includes a first shaft section 510 and a second shaft section 520. The axes of the first shaft section 510 and the second shaft section 520 are parallel but not colinear. The first shaft section 510 is coaxially connected to the gear, and the second shaft section 520 is rotatably connected to the waste powder conveying plate 200. Therefore, when the gear rotates, the second shaft section 520 will rotate around the axis of the first shaft section 510, and at the same time, the second shaft section 520 will also rotate relative to the waste powder conveying plate 200, so that the second end of the waste powder conveying plate 200 can reciprocate only within a small range, and will not flip around the gear, so that there will be no motion interference with the housing 100.
