Detailed Description

Embodiments of the present invention are described in detail below with reference to the accompanying drawings.

As described above, the process cartridge may be divided into an integrated process cartridge and a divided process cartridge according to whether the process cartridge includes a waste toner hopper containing waste toner, and embodiments of the present invention will be described below by taking the integrated process cartridge as an example.

Fig. 1 is a perspective view of a process cartridge according to the present invention.

For clarity of description, the process cartridge C is first defined as follows: the installation direction of processing box C is the place ahead, and it is the rear to take out the direction to the angle when installing is accurate, and the position at the upside place of processing box C is the top, and the position at downside place is the below, and the position at left side place is the left, and the position at right side place is right-hand, and processing box C is the biggest at the size of left right direction, therefore, the left right direction is also called longitudinal direction, and the fore-and-aft direction is also called transverse direction, and the up-and-down direction is also called vertical direction.

The process cartridge C includes a powder hopper 1 and a waste powder hopper 2 combined with each other, and a first end cap 3 and a second end cap 4 combining the powder hopper 1 and the waste powder hopper 2, wherein the powder hopper 1 includes a powder hopper body 10 containing carbon powder, the waste powder hopper 2 includes a waste powder hopper body 20 containing waste powder, and a photosensitive member 21 for forming an electrostatic latent image is rotatably installed in the waste powder hopper 2; it is realized that the powder bin 1 and the waste powder bin 2 can also be combined by means such as a pin or a snap, and not necessarily by the first end cap 3 and the second end cap 4.

Fig. 2A is a perspective view of the waste bin according to the present invention as viewed from the outside; FIG. 2B is a perspective view of the waste bin according to the present invention as viewed from the inside; fig. 3 is a sectional view of the waste powder bin according to the present invention, taken along a plane perpendicular to the left-right direction thereof.

The waste powder bin 2 is integrally formed, the waste powder bin 2/waste powder bin main body 20 includes a bottom case 20a and a cover 20b which are integrally formed, a part of the bottom case 20a and the cover 20b enclose a housing cavity 20c, the housing cavity 20c has a bottom wall 20c2 at the rear, an opening 20c3 at the front, and a cavity 20c1 between the bottom wall 20c2 and the opening 20c3 in the front-rear direction, and waste powder is housed in the cavity 20c 1. The bottom case 20a includes a rear portion 20d, an intermediate portion 20e, and a front portion 20f which are arranged in this order from the rear to the front, the photosensitive member 21 is installed at a position closer to the front portion 20f in the front-rear direction, and a grasping portion 22 for causing the process cartridge C/waste toner hopper 2 to be grasped is arranged at a position closer to the rear portion 20d, that is, the photosensitive member 21 and the grasping portion 22 are located at both ends of the waste toner hopper main body 20 in the front-rear direction, respectively.

As shown in fig. 3, the cover 20b includes an attachment plate 20b1 attached to the bottom case 20a and a seal mounting plate 20b2 attached to the attachment plate 20b1, and a seal for preventing leakage of waste toner is mounted on the seal mounting plate 20b2 in the left-right direction. Preferably, the connecting plate 20b1 is a regular plate material, and includes a first plate 20b11 extending downward from the bottom case 20a and a second plate 20b12 extending forward from the first plate 20b11, the sealing member mounting plate 20b2 is connected to the second plate 20b12, and the first plate 20b11, the second plate 20b12 and the bottom case 20a enclose the accommodating cavity 20 c.

The forward facing surface of the first plate 20b11 forms a receiving cavity bottom wall 20c2, the upward facing surface 20b4 of the second plate 20b12 is formed as a smooth surface, or the surface 20b4 of the second plate 20b12 facing the cavity 20c1 is smooth; the seal mounting plate 20b2 extends downward from the second plate 20b12, and the apex D of the seal mounting plate 20b2 (the free end point of the second plate 20b 12/the connecting plate 20b 1) is located below the surface 20b4 or on the surface 20b4 in the up-down direction, that is, in the front-back direction, there is no protrusion in the space from the intersection of the first plate 20b11 and the second plate 20b12 to the housing cavity opening 20c3, so that, when the integrated waste toner hopper 2 is produced using a mold, the in-mold row 5 for forming the housing cavity 20c does not interfere during demolding (forward movement from the rear direction), and the demolding process of the waste toner hopper body 20 can be smoothly performed.

Of course, the connection plate 20b1 may also be formed in an arc shape, in which case the boundary between the first plate 20b11 and the second plate 20b12 will not be clear, but the surface of the connection plate 20b1 facing the receiving cavity 20c is still smooth, and the connection plate 20b1 extends downward and forward from the bottom shell 20a as a whole, and the vertex D is also the vertex of the arc-shaped plate 20b1, which also ensures that the demolding of the inner row 5 can be carried out smoothly.

When the waste bin 2 is placed at an angle shown in fig. 3, the rear portion 20D extends horizontally in the front-rear direction, at least a part of the intermediate portion 20E also extends horizontally in the front-rear direction, and the front portion 20f includes an arc portion 20f1 connected to the intermediate portion 20E and a straight portion 20f2 connected to the arc portion 20f1, as shown in the drawing, the intersection of the arc portion 20f1 and the intermediate portion 20E is B, the intersection of the arc portion 20f1 and the straight portion 20f2 is a, and the end point of the straight portion 20f2 is C, so that the line segment AB is an arc line, the line segment AC is a straight line, and the straight line AC is parallel to the up-down direction, and in the front-rear direction, the straight line extending from the point D intersects the straight line AC at the point E, or the straight line extending from the point D is located below the arc line AB.

The purpose of this design is that, in the process of the inner slide 5 moving from back to front, the inner slide 5 can abut against the straight line AC, so as to smoothly separate from the bottom case 20a upwards and downwards along the plane of the straight line AC; if the straight line extending from point D intersects arc AB, then the inner slide 5 may first abut against arc AB when moving from back to front, and the arc AB will make it difficult for the inner slide 5 to disengage from the bottom case 20a from top to bottom compared to the plane of straight line AC; when the arc AB is modified to a straight line parallel to the straight line AC, although the problem that the inner row 5 is not easily separated from the bottom case 20a can be solved, it may result in that the waste toner hopper 2 as a whole is difficult to seal, and waste toner collected by the housing chamber 20c may leak from the front portion 20 f.

Further, as shown in fig. 3 in a continued manner, the intermediate portion 20e includes a rear inclined plate 20e1 connected to the rear portion 20d, a front inclined plate 20e3 connected to the front portion 20f, and an intermediate plate 20e2 located between the front inclined plate 20e3 and the rear inclined plate 20e1, the front inclined plate 20e3 and the rear inclined plate 20e1 are both inclined with respect to the front-rear direction, and the intermediate plate 20e2 is parallel to the front-rear direction, that is, the intermediate portion 20e protrudes in the up-down direction with respect to the rear portion 20d as a whole, and specifically, the intermediate portion 20e protrudes upward with respect to the rear portion 20d, so that a larger-capacity accommodation chamber 20c can be formed between the intermediate portion 20e and the cover 20 b; alternatively, the front slope plate 20e3 and the rear slope plate 20e1 may be arranged such that at least one of them is perpendicular with respect to the front-rear direction, that is, at least one of the front slope plate 20e3 and the rear slope plate 20e1 is parallel to the up-down direction, at which time the intermediate plate 20e2 protrudes upward to a position farthest from the rear portion 20 d; from the viewpoint of the design of the waste toner hopper 2 and the process cartridge C, it is preferable that each of the front and rear inclined plates 20e3 and 20e1 is inclined with respect to the front-rear direction, but the inclination angle is less than 90 °, and therefore, the description will be made below with respect to the front and rear inclined plates 20e3 and 20e1 having this structure.

As shown in the figure, the first plate 20b11 extends downward from the intersection point F of the rear oblique plate 20e1 and the middle plate 20e2, the second plate 20b12 coincides with the middle plate 20e2 along the vertical direction, or the second plate 20b12 extends forward from the first plate 20b11 along the front-rear direction not more than the middle plate 20e2, when a straight line parallel to the vertical direction is made through the point D, the straight line is compared with the middle plate 20e2 and the point H, the middle plate 20e2 is divided into a front side plate 20e21 and a rear side plate 20e22 adjacent to each other in the front-rear direction, wherein the rear side plate 20e22 is opposite to the second plate 20b12 in the vertical direction, in the embodiment of the invention, the intersection point of the front side plate 20e 21/middle plate 20e2 and the front oblique plate 20e3 is G, it is satisfied that the length m of the front side plate 20e21 is not less than the length n of the rear side plate 20e22, i.g. ≧ m, or more than m + 2 (m) or m + 2, in the process that the inner slide 5 moves forward from the cavity 20c1, since the front side plate 20e21 is parallel to the front-rear direction, the inner slide 5 does not interfere with the front side plate, and finally, the inner slide 5 smoothly comes out of the cavity 20c 1.

As can be seen from the above description, in order to enable the carry-in position 5 to be smoothly released from the accommodating cavity 20 c/cavity 20c1, the length of the portion of the middle plate 20e2 parallel to the front-rear direction, which is not opposite to the second plate 20b 12/connecting plate 20b1, in the front-rear direction should be no less than the length of the portion of the bottom plate 20a opposite to the second plate 20b 12/connecting plate 20b1, in the front-rear direction, and the length of the portion of the bottom plate 20a opposite to the second plate 20b12 in the front-rear direction is actually the depth of the accommodating cavity 20 c/cavity 20c1 in the front-rear direction, that is, the distance from the opening 20c3 of the accommodating cavity 20c to the bottom wall 20c2 in the front-rear direction; when the connecting plate 20b is formed as an arc-shaped plate, the depth of the housing cavity 20 c/cavity 20c1 in the front-rear direction means the farthest distance of the opening 20c3 from the connecting plate 20b in the front-rear direction.

In this way, in the limit that satisfies the above condition, when all of the intermediate plate 20e2 is not parallel to the second plate 20b12, the intersection point F of the first plate 20b11 and the bottom case 20a will move backward to the rear sloping plate 20e1 or the rear portion 20D, i.e. the connecting plate 20b1 will extend from a position behind the intermediate plate 20e2, but the free end point D of the second plate 20b 12/connecting plate 20b1, when projected in the up-down direction, will coincide with the intersection point F of the rear sloping plate 20e1 and the intermediate plate 20e2, i.e. the intersection point F of the rear sloping plate 20e1 and the intermediate plate 20e2 is not exceeded by the forward extension of the second plate 20b12 in the front-back direction, or the rear end point F of the intermediate plate 20e2 is not exceeded by the forward extension of the second plate 20b12 in the front-back direction, at which the portion of the bottom case 20a opposite to the connecting plate 20b1 is no longer parallel to the front-back direction, the portion of the bottom case may be referred to as the first connecting plate 20b1 (the first portion) as the front-back direction, or not parallel to the front-rear direction, at least a portion of the bottom case 20a not opposed to the connection plate 20b (e.g., the middle plate 20e2, which may be referred to as a second portion) needs to be parallel to the front-rear direction, and the length of the second portion is not less than the length of the first portion in the front-rear direction.

As described above, the waste toner receptacle 2 according to the present invention is redesigned such that the length of the portion of the intermediate plate 20e2 parallel to the front-rear direction, which is not opposed to the second plate 20b12, is not smaller than the length of the portion of the bottom shell 20a opposed to the second plate 20b12 in the front-rear direction, and when the slide 5 needs to be removed from the housing cavity 20c, it only needs to be moved forward from the rear in the front-rear direction, and therefore, the waste toner receptacle 2 can be integrally molded using the embodiment of the present invention.
