The utility model is described in further detail below with reference to the accompanying drawings.

Fig. 1 and 2 schematically show a waste bin structure according to an embodiment of the present utility model. As shown in the drawing, the waste powder bin of the present utility model includes a waste powder bin frame 110 and a waste powder bin cover 120, the waste powder bin frame 110 is a hollow rectangular frame body as a whole, and fixing openings for installing photosensitive elements are provided at left and right sides of the length direction thereof. For ease of understanding, the description is schematically illustrated with three axes, in which the X axis is the length direction of the waste bin frame 110, the Y axis is the width direction of the waste bin frame 110, and the Z axis is the height direction of the waste bin frame 110. In the Y-axis direction, the waste bin frame 110 includes a front portion 111 and a rear portion 112, wherein the front portion 111 is used for mounting a cleaning member (not shown) and a photosensitive member (not shown), and forms an original waste powder accommodating chamber together with the cleaning member and the photosensitive member, the rear portion 112 is used for fixedly connecting with the waste bin cover 120, and a mating portion of the rear portion 112 and the waste bin cover 120 is of a convex structure, thereby forming a newly added waste powder accommodating chamber a, and the rear portion 112 is further provided with a handle (not shown) for facilitating grasping by a user.

Wherein, the front part 111 and the rear part 112 are adjacently arranged by taking the Y axis as an illustration, and the waste powder bin frame 110 is divided into a front part and a rear part, and the front part and the rear part can be integrally formed by direct injection molding. Further, the rear portion 112 includes two limiting portions 113 protruding in the Z-axis direction, which are located at two sides of the rear portion 112, symmetrically disposed in the Y-axis direction, and fixedly connected to the rear portion 112, and the limiting portions 113 are mainly fixedly engaged with the waste bin cover 120.

Specifically, in the present embodiment, the limiting portion 113 includes a connecting portion 1131 perpendicular to the X direction and an arc-shaped expansion portion 1132, the connecting portion 1131 is fixedly connected to the bottom end of the rear portion 112, the expansion portion 1132 is fixedly connected to the connecting portion 1131, in the Y axis direction, the length of the expansion portion 1132 is longer than that of the connecting portion 1131, and the center of gravity of the waste powder bin frame 110 is taken as the center, the expansion portion 1132 extends toward the front portion 111 and gradually approaches to both side walls of the waste powder bin frame 110 until the expansion portion 1132 is joined to the front portion 111, that is, the expansion portion 1132 and the connecting portion 1131 form an obtuse angle, and by this structural design, the limiting portion 113 and the rear portion 112 jointly surround a newly added waste powder accommodating cavity a with a wide front and narrow rear portion, that is, the space of the waste powder accommodating cavity a gradually increases toward the front portion 111, so that the space for accommodating residual developer is increased to a certain extent, and the phenomenon that the residual developer overflows from the waste powder bin can be avoided.

As shown in fig. 2 and 3, in some embodiments, the waste bin cover 120 is provided with a notch 125, and the limit portion 113 is correspondingly provided with a protrusion 1133, and the protrusion 1133 and the notch 125 may be engaged, so as to provide a matching structure of the waste bin cover 120 and the waste bin frame 110, where two notches 125 and two protrusions 1133 may be used, and it should be noted that the shape of the waste accommodating cavity a formed by the limit portion 113 corresponds to that of the waste bin cover 120. In addition, the waste bin cover 120 may be fixed to the waste bin frame 110 by welding or cementing.

In this embodiment, the protrusion 1133 is located in the middle of the connection 1131 in the Y-axis direction, and the size of the protrusion 1133 may be set according to practical requirements, and the protrusion 1133 is mainly matched with the notch 125, and the notch 125 is located in the lower half of the waste bin cover 120, and the position of the notch corresponds to the protrusion 1133.

It should be noted that, the waste bin frame 110 is provided with hollow structures on both sides of the rear part 112, and the hollow parts are necessary to be left, because there are two protruding structures in the bin part (not shown in the figure), and when the bin is used in combination with the waste bin, the waste bin frame 110 needs to be provided with the two hollow structures to cooperate with the protrusions of the bin to ensure the normal use of the process cartridge. At the same time, the hollow structure is designed such that the expansion portion 1132 extends and expands to both sides of the X axis.

In some embodiments, as shown in fig. 3 and 4, the waste bin cover 120 includes a first plate 122 and a second plate 124, wherein an end of the waste bin cover 120 adjacent to the first plate 122 is a front end in the Y-axis direction, and a height of the first plate 122 in a direction perpendicular to the waste bin frame 110, i.e., a height in the Z-axis direction is smaller than the second plate 124, and in particular, the first plate 122 and the second plate 124 have a height difference. When the waste bin cover 120 is mounted on the waste bin frame 110, the front end of the waste bin cover 120 and the waste bin frame 110 form an opening 130, and under normal conditions, the cleaning element transfers the residual developer on the photosensitive element to the opening 130, then passes through the space formed by the first plate 122 and the waste bin frame 110, and finally flows to a larger storage space formed by the second plate 124 and the waste bin frame 110.

Wherein, the waste bin cover 120 further includes a transition portion 123 between the first plate 122 and the second plate 124, connecting the first plate 122 and the second plate 124, and the transition portion 123 is of an inclined structure, extending obliquely upward to the first plate 122 through the second plate 124, and the transition portion 123 is of a slope structure, so that the residual developer is more easily moved into a larger storage space formed by the second plate 124 and the waste bin frame 110 by the action of gravity.

In the Y-axis direction, the first plate 122 and the second plate 124 are respectively two front and rear parts of the waste powder bin cover 120, the first plate 122 is close to the front part 111, and the area of the second plate 124 is relatively larger, so that the waste powder bin cover 120 has a shape corresponding to the storage space of the rear part 112 and also has a structure with wide front and narrow rear. Specifically, the front end of the waste bin cover 120 is provided with a supporting portion 121, which is a strip-shaped structure fixedly connected to the waste bin cover 120 and protruding toward the front portion 111, and is used for supporting a cleaning element (not shown in the figure), a sponge strip (not shown in the figure) may be disposed between the cleaning element and the supporting portion 121, so as to prevent the cleaning element from leaking out in the process of conveying the residual developer on the photosensitive element to the accommodating cavity a formed by the waste bin cover 120 and the waste bin frame 110, as seen in a cross-sectional view along the length direction of the waste bin, the first plate 122 and the second plate 124 are parallel to each other, and the transition portion 123 is obliquely disposed, and it is understood that the transition portion 123 is an oblique extending portion between the first plate 122 and the second plate 124, and the distance from the first plate 122 to the waste bin frame 110 in the Z direction is smaller than the distance from the second plate 124 to the waste bin frame 110 in the Z direction, i.e. the space formed by the second plate 124 in the Z direction is larger than the space formed by the first plate 122 in the Z direction, and the residual developer is further stored in the structure to a certain extent.

And because the waste powder bin cover 120 and the accommodating cavity A formed by the waste powder bin cover are designed to be wide in front and narrow in back, when the waste powder bin collects residual developer, the residual developer can enter the accommodating cavity A more and faster, and meanwhile, the residual developer at the first plate 122 is easier to move to the second plate 124 with larger space due to the inclined arrangement of the transition part 123, so that the residual developer is effectively prevented from accumulating to the position of the opening 130, and the residual developer is easier to store in a wider space.

It can be seen from the above that: the waste powder bin frame is provided with a front part and a rear part, the front part is mainly used for installing the photosensitive element, the front part is also used as a part of an original waste powder bin, the rear part and the waste powder bin cover are fixedly connected to form a part for increasing the waste powder bin, the storage space of residual developer can be expanded, the limit part at the rear part is expanded to the front part and matched with the waste powder bin cover to form a structure with wide front part and narrow rear part, the storage space of residual developer is increased, in addition, the first plate and the second plate of the waste powder bin cover have a height difference, the storage space of residual developer is further increased, and an inclined transition part is also arranged.

What has been described above is merely some embodiments of the present utility model. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit of the utility model.
