The developing box stores the toner required for development, and the developing box is also provided with a driving force receiving member and a developing roller rotatably provided for carrying the toner. When the developing box is developing in the imaging device, the driving force receiving member cooperates with the driving force output member to receive the driving force, and then the developing roller can be driven to rotate by the driving force received by the driving force receiving member.

[0021] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0022] [Overall structure of the developer cartridge]

[0023] The developing box 100 involved in the utility model can be directly or indirectly installed in a detachable manner to an imaging device provided with a driving force output member. In one feasible manner, the developing box 100 is directly installed to the imaging device. In another feasible manner, the developing box 100 can be first combined with a drum box provided with a photosensitive drum, and then the combination of the developing box 100 and the drum box is installed to the imaging device. The developing box 100 and the drum box can be combined in a detachable manner or in a movable manner. For example, the developing box 100 and the drum box are combined in a hinged, sliding connection, etc.

[0024] like Figure 1 and Figure 2 As shown, the developing box 100 includes a shell 1, a rotating member 2 and a driving force receiving member 3. The rotating member 2 is rotatably arranged in the shell 1. The driving force receiving member 3 is used to receive a driving force from the imaging device to drive the rotating member 2 to rotate. Specifically, the driving force receiving member 3 is combined with a driving force output member. The driving force receiving member 3 can be directly combined with the rotating member 2. At this time, the driving force received by the driving force receiving member 3 will be directly transmitted to the rotating member 2. The driving force receiving member 3 can also be combined with the rotating member 2 through an intermediate component. At this time, the driving force received by the driving force receiving member 3 will be transmitted to the rotating member 2 through the intermediate component.

[0025] Further, the developing box 100 includes a developing roller 21, a powder feeding roller 22 and a stirring frame 23. A cavity 10 for accommodating toner is formed in the housing 1. The stirring frame 23 is located in the cavity 10 and is used to stir the toner stored in the cavity 10. The powder feeding roller 22 is used to supply toner to the developing roller 21. The developing roller 21 carries toner and supplies toner to the photosensitive drum outside the developing box, so that the electrostatic latent image formed on the surface of the photosensitive drum is developed, as shown in FIG. Figure 1 As shown, the developing roller 21 rotates around the first rotation axis L1, and the powder feeding roller 22 rotates around the second rotation axis L2. The first rotation axis L1 and the second rotation axis L2 are parallel to each other, and the extension direction of the first rotation axis L1 and the extension direction of the second rotation axis L2 are the longitudinal direction of the developing box 100.

[0026] The developing roller 21 , the powder feeding roller 22 and the stirring frame 23 are all rotatably arranged in the housing 1 , so the rotating member 2 can be regarded as at least one of the developing roller 21 , the powder feeding roller 22 and the stirring frame 23 .

[0027] The developing roller 21 includes a developing roller layer 211 and a developing roller shaft 212, and the developing layer 211 is coated on the surface of the developing roller shaft 212. The powder feeding roller 22 includes a powder feeding layer 221 and a powder feeding roller shaft 222, and the powder feeding layer 221 is coated on the surface of the powder feeding roller shaft 222. Generally, the powder feeding layer 221 is made of a porous elastic material (such as sponge), so that the powder feeding layer 221 can accommodate and transport carbon powder. The developing layer 211 is also made of an elastic material, but in general, the hardness of the developing layer 211 is greater than the hardness of the powder feeding layer 221.

[0028] Along the longitudinal direction, the driving force receiving member 3 is located at one end of the developing box. In the following, the driving force receiving member 3 is directly combined with the powder feeding roller shaft 222 as an example. That is to say, in the developing box 21 and the powder feeding roller 22 in the developing box 100 involved in the utility model, the powder feeding roller 22 is directly driven by the driving force receiving member 3, and the developing roller 21 is driven by the driving force from the powder feeding roller 22. For example, along the longitudinal direction, at least one of the two ends of the developing box 100 is provided with a driving force transmission member, and the driving force received by the driving force receiving member 3 is transmitted to the developing roller 21 through the driving force transmission member.

[0029] This design is beneficial to reducing the influence of the vibration generated by the driving force receiving member 3 during rotation on the position of the developing roller 21 relative to the photosensitive drum, especially at the moment when the driving force receiving member 3 is driven, the vibration generated by the driving force receiving member 3 is greater; as mentioned above, since the hardness of the powder feeding layer 221 is smaller than the hardness of the developing layer 211, even if the powder feeding roller 22 is affected by the vibration of the driving force receiving member 3, the powder feeding layer 221 can absorb the vibration, so that the position of the developing roller 21 relative to the photosensitive drum will not change easily. Finally, the imaging quality of the developing box 100 can remain stable.

[0030] According to the inventive concept of the utility model, when the developing roller 21 adopts other vibration reduction methods, or the influence of the vibration on the position of the developing roller 21 relative to the photosensitive drum is not considered, the driving force receiving member 3 can also be directly combined with the developing roller shaft 212.

[0031] [Structure of driving force receiving member]

[0032] like Figure 3A , Figure 3B , Figure 4A and Figure 4B As shown, the driving force receiving member 3 is formed in one piece, including a matching portion 31 and a main body portion 32. The main body portion 32 is used to combine with the driving force output member to receive the driving force, and the matching portion 31 is used to transmit the driving force. When the driving force receiving member 3 is directly combined with the powder feeding roller shaft 222, the matching portion 31 will be combined with the powder feeding roller shaft 222.

[0033] The mating portion 31 is formed as a columnar body, preferably a cylindrical body, and a mating cavity 314 is formed in the mating portion 31 to allow the driven part (powder feeding roller shaft 222) outside the driving force receiving member 3 to enter. Furthermore, the mating portion 31 also includes a driving portion 315 arranged in the mating cavity 314, so that when the driving portion 315 is cut along a plane perpendicular to the rotation axis L2, the cross-sectional surface of the mating portion 31 will be non-circular. The mating portion 31 transmits the driving force to the driven part through a driving surface 316 arranged on the driving portion 315. Preferably, the driving surface 316 faces the rotation axis L2, and more preferably, the driving surface 316 and the rotation axis L2 are parallel to each other.

[0034] The main body 32 includes a base 36 and a driving claw 33 which are connected to each other. Along the radial direction of the driving force receiving member 3, the base 36 is located radially outside the driving claw 33, or in other words, the base 36 is farther away from the rotation axis L2 than the driving claw 33; the base 36 is formed as an arc-shaped body extending along the rotation direction r of the driving force receiving member 3, wherein a coupling cavity 35 is formed to allow the driving force output member to enter, and along the rotation axis of the driving force receiving member 3, the coupling cavity 35 is connected to the matching cavity 314, preferably, the base 36 is formed as a cylindrical body, so that the base 36 can not only effectively protect the driving claw 33, but also limit the possible swing of the driving claw 33 and the driving force output member after being coupled with each other; along the rotation direction r of the driving force receiving member 3, a plurality of driving claws 33 are arranged in the coupling cavity 35 at intervals, and the structure of each driving claw 33 is the same, and only one of the driving claws 33 is selected for description below.

[0035] The driving claw 33 includes a root portion 331 and an action portion 332 that are connected to each other, the root portion 331 is connected to the base portion 36, and the action portion 332 extends from the root portion 331. As a whole, the driving claw 33 is formed in a cantilever shape, and the action portion 332 can swing around the root portion 331 in a direction close to the rotation axis L2 and in a direction away from the rotation axis L2. The action portion 332 basically extends along the rotation direction r, and includes a first connection portion 3a, a second connection portion 3b and an action protrusion 3c. The first connection portion 3a connects the second connection portion 3b and the root 331, and the second connection portion 3b connects the first connection portion 3a and the action protrusion 3c. Along the radial direction of the driving force receiving member 3, the action portion 332 has an outer surface 333 that is opposite to the rotation axis L2, wherein the outer surface 333 is opposite to the rotation axis L2. The portion corresponding to the first connection part 3a is a straight surface CA, and the portion of the outer surface 333 corresponding to the second connection part 3b is an arc surface AB, that is, on the outer surface 333, the starting point of the first connection part 3a is C, and the end point is A, the starting point of the second connection part 3b is A, and the end point is B. Along the rotation direction r, the straight surface CA is closer to the root 331 than the arc surface AB, or in other words, the arc surface AB is located downstream of the straight surface CA. Compared with the straight surface CA being located downstream of the arc surface AB, in the radial direction of the driving force receiving member 3, the driving claw 33 in the present application can obtain a larger activity space, that is, the driving claw 33 in the present application has a larger displacement; preferably, along the rotation axis L2 of the driving force receiving member 3, the arc surface AB is opposite to the through hole 213, or in other words, the arc surface AB is exposed through the through hole 213.

[0036] Along the rotation direction r, the action protrusion 3c extends from the second connecting part 3b in the direction away from the first connecting part 3a, and along the radial direction of the driving force receiving member 3, at least a part of the action protrusion 3c is closer to the rotation axis L2 than the second connecting part 3b, that is, at least a part of the action protrusion 3c protrudes from the second connecting part 3b toward the rotation axis L2.

[0037] The action protrusion 3c includes a force-bearing surface 3c1, a first guide surface 3c2, a second guide surface 3c4 and a retaining surface 3c3, wherein the force-bearing surface 3c1 is used to abut against the driving force output member to receive the driving force, the first guide surface 3c2 and the second guide surface 3c4 are respectively located on both sides of the retaining surface 3c3, along the rotation axis L2, the first guide surface 3c2 is farther away from the matching portion 31 than the second guide surface 3c4, in the process of the driving force receiving member 3 and the driving force output member being combined, the first guide surface 3c2 is used to guide the driving force receiving member 3 / driving claw 33, so that the driving claw 33 can be smoothly combined with the driving force output member, and the second guide surface 3c4 is used to guide the driving force receiving member 3 / driving claw 33. 2. During the process of disengagement of the driving force receiving member 3 and the driving force output member, the second guide surface 3c4 is used to guide the driving force receiving member 3 / driving claw 33 so that the driving claw 33 can be smoothly disengaged from the driving force output member. When observed along the rotation axis L2 of the driving force receiving member 3, the second guide surface 3c4 is exposed through the through hole 213; at least a portion of the retaining surface 3c3 faces the rotation axis L2, and when the driving force receiving member 3 / driving claw 33 completes the engagement with the driving force output member, the retaining surface 3c3 cooperates with the surface of the driving force output member so that the driving force receiving member 3 and the driving force output member remain in a stably engaged state.

[0038] As shown in the figure, the action protrusion 3c also includes an end face 3c5, and along the rotation direction r, the end face 3c5 is located at the end of the driving claw 33, that is, the end face 3c5 faces the downstream of the driving claw 33 where it is located, and along the rotation direction r, the force surface 3c1 and the end face 3c5 are respectively located on both sides of the action protrusion 3c.

[0039] like Figure 4B As shown, along the radial direction of the driving force receiving member 3, the end surface 3c5 has a distal end point D and a proximal end point E, wherein the distal end point D is farther from the rotation axis L2 than the proximal end point E. Figure 4B In the figure, the line d1 connecting the projection point of the rotation axis L2 and the far end point D is not colinear with the line d2 connecting the projection point of the rotation axis L2 and the near end point E, and along the rotation direction r, the line d2 is located upstream of the line d1. In this way, during the installation of the driving force receiving member 3 along with the developing box 100, even if a foreign object abuts against the end surface 3c5, the driving claw 33 can smoothly avoid the foreign object by swinging around the root 331 in the direction away from the rotation axis L2.

[0040] The main body 32 also includes a transmission part 312. Along the rotation axis L2, the transmission part 312 is located between the driving claw 33 and the matching part 31, and also between the base 36 and the matching part 31. The transmission part 312 is used to transmit the driving force received by the driving claw 33 to the matching part 31. The matching part 31 is connected to one end of the transmission part 31, and at least one of the base 36 and the driving claw 33 is connected to the other end of the transmission part 312. That is, the driving claw 33 can be extended from at least one of the base 36 and the transmission part 312, or in other words, at least one of the base 36 and the transmission part 312 is connected to the root 331 of the driving claw 33. The driving force received by the driving claw 33 can be transmitted to the transmission part 312 through at least one of the base 36 and the driving claw 33, and then transmitted to the matching part 31 by the transmission part 312. Finally, the matching part 31 transmits the driving force.

[0041] In some embodiments, the action protrusion 3c can also be integrally provided with the second connecting portion 3b. In this case, the end point B of the second connecting portion 3b will coincide with the distal end point D.

[0042] When the driving claw 33 is extended from the base 36 and the transmission part 312 at the same time, it can not only increase the strength of the driving claw 33, but also effectively control the swing / movement amount of the driving claw 33 in the radial direction of the driving force receiving member 3, thereby preventing the driving claw 33 from being unable to stably combine with the driving force output member.

[0043] Furthermore, the driving force receiving member 3 also includes a through hole 313 arranged in the main body 32. Along the radial direction of the driving force receiving member 3, the through hole 313 is located on the radial outside of the matching portion 31. Along the rotation direction r, the through holes 313 and the transmission portions 312 are alternately arranged. Preferably, the number of the through holes 313, the number of the transmission portions 312, and the number of the driving claws 33 are the same. For example, the through holes 313, the transmission portions 312 and the driving claws 33 are all set to 3; along the rotation axis L2, a portion of the driving claw 33 is opposite to the through hole 313, that is, when observed along the rotation axis L2, a portion of the driving claw 33 will be observed. This structural design is conducive to realizing the integration of the driving force receiving member 3.

[0044] like Figure 4A As shown, along the rotation axis L2, at least a portion of the action portion 332 is also spaced apart from the transmission portion 312, so that the driving claw 33 / action portion 332 can be formed into a cantilever shape, so that the driving claw 33 / action portion 332 can swing in the radial direction when receiving a force in the radial direction; Figure 4B As shown, at least a portion of the acting portion 332 is spaced apart from the base portion 36 in the radial direction of the driving force receiving member 3 , so that the acting portion 332 has space to move away from the rotation axis L2 .

[0045] Preferably, along the rotation axis L2, the action protrusion 3c is opposite to the through hole 313, that is, the action protrusion 3c is suspended. This design will enable the action protrusion 3c to be deformed more easily, or in other words, the driving claw 33 / action protrusion 3c will be able to move more easily in the radial direction relative to the root 331, so that the driving claw 33 / action protrusion 3c and the driving force output member can be smoothly combined and disengaged.

[0046] In some embodiments, Figure 4B As shown, along the rotation axis L2, at least a portion of the second connecting portion 3b and the action protrusion 3c are opposite to the through hole 313. Preferably, along the rotation direction r, the starting point A and the end point B of the second connecting portion 3b are both located within the range of the through hole 313. In this way, along the radial direction of the driving force receiving member 3, the driving claw 33 / the action portion 332 can produce a larger deformation amount, and accordingly, the engagement process and the disengagement process of the driving force receiving member 3 and the driving force output member are smoother.

[0047] In some embodiments, along the rotation axis L2, at least a portion of the first connecting portion 3a, the second connecting portion 3b and the action protrusion 3c are opposite to the through hole 313. Compared with the previous deformation method, this design can produce a larger deformation amount of the driving claw 33 / the action portion 332, and the engagement process and disengagement process of the driving force receiving member 3 and the driving force output member will also be smoother.

[0048] In summary, when the driving force receiving member 3 is integrally molded, along the rotation axis L2, in the mold, the core used to form the relative part of the driving claw 33 relative to the through hole 313 can be smoothly demolded from the through hole 313 in the direction from the main body 32 toward the mating part 31 (demolding direction).

[0049] According to the above description, the relative part includes at least the functional protrusion 3c; in some embodiments, the relative part may include at least a portion of the second connecting part 3b and the functional protrusion 3c; in some embodiments, the relative part may include a portion of the first connecting part 3a, the second connecting part 3b and the functional protrusion 3c.

[0050] Assuming that the through hole 313 is not provided, or the through hole 313 is provided but the corresponding portion does not exist in the driving claw 33, when the driving force receiving member 3 is integrally molded, the mold core for forming the driving claw 33 will not be able to be demolded from the demolding direction. Furthermore, for the driving claw 33, at least a gap needs to be formed between the action protrusion 3c and the transmission part 312 to ensure that the action protrusion 3c can exist in the form of a cantilever, so that the action protrusion 3c can swing / move in the radial direction of the driving force receiving member 3. Therefore, a part of the mold core must be located A gap is formed between the acting protrusion 3c and the transmission part 312, but in the direction opposite to the demolding direction, the mold core located between the acting protrusion 3c and the transmission part 312 cannot be ejected. To realize this structure, the main body 32 and the matching part 31 of the driving force receiving part 3 need to be formed separately. Obviously, the separately arranged main body 32 and the matching part 31 not only increase the number of parts of the driving force receiving part 3, complicate assembly, and reduce production efficiency, but also cause the precision of the driving force receiving part 3 to decrease.

[0051] As described above, the driving force receiving member 3 can also directly cooperate with the rotating member 2. For example, the driving force receiving member 3 is directly installed on the developing roller shaft 212 or the powder feeding roller shaft 222, etc. Then, the driving force receiving member 3 can directly drive the rotating member 2 to rotate after receiving the driving force. At this time, the combination of the driving force receiving member 3 and the rotating member 2 can be called a rotating component.

[0052] Furthermore, the rotating member 2 and the driving force receiving member can be separately and independently arranged in the housing 1, or they can be combined into a rotating assembly and then arranged in the housing 1.

[0053] Furthermore, the developing box 100 provided with the driving force receiving member 3 or the rotating component can also be combined with the drum box to form a processing box, and the processing box can be installed in a detachable manner to the imaging device. It can be understood that the developing box 100 can also be directly installed in a detachable manner to the imaging device, and the drum box can be provided with a photosensitive drum that can form an electrostatic latent image, or the photosensitive drum may not be provided.

[0054] [Beneficial Effects]

[0055] According to the inventive concept of the utility model, the technical solution of the utility model has the following beneficial effects:

[0056] 1. The provision of the through hole 313 allows the driving force receiving member 3 to be integrally molded, and the mold for forming the driving force receiving member 3 can be smoothly demolded along the demolding direction, thereby simplifying the structure of the driving force receiving member 3 without the need for additional assembly. Accordingly, the cost of the driving force receiving member 3 is reduced.

[0057] 2. In the driving claw 33, the through hole 313 can also enable at least the action protrusion 3c to be formed into a cantilever shape, so that the action protrusion 3c can swing / move in the radial direction of the driving force receiving member 3, thereby making the mutual engagement and disengagement of the driving force receiving member 3 and the driving force output member smoother.
