[0045] Embodiment 1

[0046] This embodiment discloses a processing box in which, during the installation process, the movable parts will not squeeze the protrusion of the electronic imaging device and will not cause the protrusion to sink. In this application, the top, bottom, left side, and right side of the processing box are all the directions when the processing box is installed inside the electronic imaging device, and the front and rear side refer to the front and rear side of the installation direction of the processing box to the electronic imaging device during the installation process. During the installation of the processing box, for example, it can be stipulated that the powder bin part is in the front and the waste powder bin part is in the back.

[0047] Figure 1 This is a structural view of the top of the process box when it is installed inside the electronic imaging device. Figure 1 As shown, the process box includes a waste toner bin portion 100 and a powder bin portion 200. The waste toner bin portion 100 includes a waste toner bin upper portion 110 above the process box; similarly, the powder bin portion 200 includes a powder bin upper portion 210 above the powder bin portion 200.

[0048] Figure 2 This is a structural view of the bottom of the process box when it is installed inside the electronic imaging device. Figure 2 As shown, the waste toner bin portion 100 includes a photosensitive drum 120 below, and the powder bin portion 200 includes a powder bin lower portion 220 below. The process box further includes a movable component 230, which is movably mounted on the powder bin lower portion 220.

[0049] Figure 3 It is a cross-sectional view of the process box cut along a plane perpendicular to the length direction of the process box. Figure 3As shown, the movable component 230 is movably connected to the powder bin portion 200. In some implementations, the position of the movable component 230 on the processing box is closer to the bottom than the bottom 220 of the powder bin, that is, at least a portion of the movable component 230 protrudes relative to the bottom 220 of the powder bin, so that when the processing box is installed in the electronic imaging device along the direction of arrow E, the movable component 230 will first touch or abut the protrusion installed inside the electronic imaging device. By providing the movable component 230 to replace the fixed component in the background technology, during the installation of the processing box, the movable component 230 can move relative to the protrusion, so that the protrusion inside the electronic imaging device is no longer retracted downward in the vertical direction due to the installation of the processing box. In this embodiment, the movable component 230 will move due to the force of the protrusion. Of course, the movable component 230 can also move due to the force of other parts inside the electronic imaging device.

[0050] Figure 4 and Figure 5 It is a cross-sectional schematic diagram of two different positions of the movable component on the processing box. Figure 4a and Figure 5a yes Figure 4 and Figure 5 The enlarged view of the movable part 230 in the corresponding state. The matching relationship between the powder bin part 200 and the movable part 230 is a clearance fit, so the movable part 230 can move relatively freely relative to the powder bin part 200. In order to prevent the movable part 230 from detaching from the powder bin part 200, as shown in FIG. Figure 4 and Figure 4a As shown, the powder bin part 200 further includes a containing bin 240, and a part of the movable component 230 is located in the containing bin 240. In this embodiment, the movable component 230 includes a resisting portion 233, and the containing bin 240 includes an anti-detaching portion 241. Due to the interference between the resisting portion 233 and the anti-detaching portion 241, the movable component 230 will not detach from the powder bin part 200.

[0051] The movable component 230 has an abutting surface 231 that can abut against the electronic imaging device. When the processing box is installed in the electronic imaging device, driven by some mechanisms in the electronic imaging device (for example, a connecting rod mechanism is triggered when the door cover of the electronic imaging device is closed or opened, and the above-mentioned mechanism is not shown in the figure), the processing box will be lowered along the arrow F direction, so that the abutting surface 231 abuts against the protrusion of the electronic imaging device. At this time, the movable component 230 will be retracted into the processing box along the arrow P, that is, Figure 4 and Figure 4aThe state shown in is called the first position at this time. In addition, since there is a clearance fit between the movable component 230 and the powder bin portion 200, the resistance generated by the relative movement is small, so the movable component 230 will not squeeze the protrusion downward at this time. When the processing box is installed in place, the internal movement of the electronic imaging device causes the protrusion to move in the opposite direction of the processing box installation, and the protrusion leaves the position abutting against the abutting surface 231 and moves to the side close to the pushing surface 232. At this time, since there is a clearance fit between the movable component 230 and the powder bin portion 200 and the protrusion no longer abuts against the abutting surface 231, the movable component 230 is extended downward along the arrow Q relative to the processing box due to the effect of gravity. At this time (after the movable component 230 is extended), the pushing surface 232 can contact the protrusion, and at this time ( Figure 5 and Figure 5a ) is called the second position. Of course, when in the second position, the stopper 233 on the movable part 230 may not contact the anti-slip portion 241 because other parts in the electronic imaging device abut against the movable part 230, or other parts inside the processing box exert an effect on the movable part 230. However, as long as the second position is closer to the bottom of the processing box than the first position, and at least a part of the projection of the pushing surface 232 in the front or rear coincides with the projection of the protrusion in the front or rear (the overlap of one of the front or rear can be regarded as the projection overlap), it can be regarded as the second position.

[0052] When the movable part is located in the second position and the electronic imaging device drives the protrusion to move along the processing box installation direction (direction of arrow E), the protrusion can exert force on the pushing surface 232 and push the powder bin part 200 to move relative to the waste powder bin part 100 and separate the roller drum.

[0053] Figure 6 This is a cross-sectional view of an optimized structure of the movable part along a plane perpendicular to the length direction of the processing box. Figure 6 In the figure, the new pushing surface 234 with the dotted line part replaces the previous pushing surface 232. The new pushing surface 234 is kept perpendicular to the horizontal plane when the process cartridge is installed in the electronic imaging device, so as to adapt to the situation where a special-shaped protrusion contacts. Through such an arrangement, the force between the special-shaped protrusion and the pushing surface is also the same as that of other protrusions, and the pushing force is directed parallel to the horizontal direction, so that the roller-drum separation is performed more smoothly.

[0054] Embodiment 2

[0055] This embodiment discloses a processing box in which, during the installation process, the movable parts will not squeeze the protrusion of the electronic imaging device and will not cause the protrusion to retract downward. In this application, the top, bottom, left side, and right side of the processing box are all the directions when the processing box is installed inside the electronic imaging device, and the front and rear side refer to the front and rear side of the installation direction of the processing box to the electronic imaging device during the installation process. During the installation of the processing box, for example, it can be stipulated that the powder bin part is in the front and the waste powder bin part is in the back.

[0056] Figures 7 to 10 The schematic diagram of the working principle of the processing box in different states in this embodiment is shown in FIG. Figures 7 to 10 In the figure, the waste powder bin part is omitted and not shown. The powder bin part 1200 includes a movable part 1230, a first pushing part and a second pushing part. The first pushing part has a tendency to push the movable part 1230 downward so that the movable part 1230 extends downward in the vertical direction. For example, the first pushing part may include a first elastic member 1210 and a push plate 1240 connected to the first elastic member 1210. The second pushing part has a tendency to push or pull the movable part 1230 to move away from the waste powder bin part. For example, the second pushing part may include a second elastic member 1220, and the second elastic member 1220 is connected to the movable part 1230. In other words, the first pushing part can be subjected to a force applied by the movable part 1230 in the vertical direction, and the second pushing part can be subjected to a force applied by the movable part 1230 in the horizontal direction. For example, when the movable component 1230 is in the first position, it can be considered that only the first pushing component is subjected to the force of the movable component 1230 in the vertical direction, and when the movable component 1230 is in the second position, it can be considered that the first pushing component is subjected to the force of the movable component 1230 in the vertical direction and the second pushing component is subjected to the force of the movable component 1230 in the horizontal direction. The powder bin portion 1200 also includes a locking component 1250, and the locking component 1250 does not interfere with the movable first pushing component and / or the second pushing component. The locking component 1250 can act on the movable component 1230 at a specific position so that the movable component 1230 no longer moves relative to the powder bin portion 1200. In some implementations, the movable component 1230 fixed by the locking component 1250 at this specific position can be regarded as the movable component 1230 being rigidly connected to the powder bin portion 1200.

[0057] When the process cartridge is installed in the electronic imaging device and the door cover of the electronic imaging device is not closed, the process cartridge is installed in the direction of arrow E from the right side in the figure to the left side in the figure. Figure 7 The powder bin portion 1200 shown in the figure is the process box installed at the innermost side of the electronic imaging device. When the process box is installed in the electronic imaging device and the door cover of the electronic imaging device is not closed, as shown in FIG. Figure 7As shown, under the action of the first pushing member and the second pushing member, the movable member 1230 is extended relative to the processing box in the vertical direction and is also located away from the side of the waste toner bin.

[0058] like Figure 8 As shown, when the door cover of the electronic imaging device is closed, under the action of the connecting rod mechanism (not shown in the figure) in the door cover, the processing box will descend in the vertical direction (direction of arrow F), and the movable part 1230 will contact the movable rod 70 with a protrusion 71 inside the electronic imaging device. In some implementation schemes, the movable part 1230 is stuck in the groove 72 on the movable rod 70, and the movable rod 70 presses the movable part 1230 to make the movable part 1230 rise a certain distance in the vertical direction. This is called the first position, that is, in the first position, the movable part will apply a force in the vertical direction to the first pushing part. The groove 72 in this figure is only a possible position, and the groove 72 can also be relatively located on the right side of the protrusion 71 in the figure. It can be understood that the protrusion 71 in this embodiment can also be retracted in the vertical direction, but in this embodiment, only the protrusion 71 and the movable rod 70 with the protrusion 71 are shown.

[0059] Afterwards, the internal movement of the electronic imaging device will drive the movable rod 70 to move a short distance in the direction opposite to the direction in which the process cartridge is installed toward the electronic imaging device (direction of arrow I), such as Fig. 9 As shown. At this time, the movable rod 70 will drive the movable part 1230 to move along the arrow I toward the waste powder bin (i.e., opposite to the direction in which the processing box is installed toward the electronic imaging device). When the movement ends, it reaches the specific position where the locking part 1250 and the movable part 1230 act. At this time, the movable part 1230 is fixed relative to the powder bin part 1200 under the action of the locking part 1250 and no longer moves. This is called the second position, that is, in the second position, the movable part will apply a force in the vertical direction to the first pushing part and a force in the horizontal direction to the second pushing part. In this embodiment, the movable part 1230 in the first position and the second position state are at the same height, but it is still understandable that the movable part 1230 in the first position will retract into the inside of the processing box, and the movable part 1230 in the second position can receive the forced thrust provided by the electronic imaging device. After that, whether the movable rod 70 moves along the direction in which the processing box is installed toward the electronic imaging device, or returns to this position, the movable part 1230 will no longer move relative to the powder bin part 1200. Therefore, when the movable rod 70 moves in the direction of installing the processing box toward the electronic imaging device (the direction of arrow I'), the powder bin part 1200 can be pushed to separate relative to the waste powder bin part, thereby completing the roller-drum separation.

[0060] like Fig.10As shown in the figure, when printing is not performed and the door cover of the electronic imaging device is opened, the processing box will rise in the vertical direction (arrow F' direction), at which time the movable rod 70 is no longer in contact with the movable part 1230, and the first pushing part will push the movable part 1230 to extend downward in the vertical direction so that the movable part 1230 is no longer in a specific position with the locking part 1250, so that the locking part 1250 can no longer fix the movable part 1230 on the powder bin part 1200. Then the second movable part pulls the movable part 1230 to move away from the waste powder bin (arrow Z direction) and returns to the Figure 7 That is, when the movable part 1230 extends downward in the vertical direction, the movable part 1230 is limited in the horizontal direction by the locking part 1250; when the movable part 1230 is fully extended, the movable part 1230 is returned to the first position by the force of the second pushing part.

[0061] In other implementations, such as Fig.11 As shown, instead of using the movable part 1230 to cooperate with the groove 72, a hook is provided at the free end of the movable part 1230. In some implementations, the hook includes claw teeth 1231 and a pressing portion 1232. As the pressing portion 1232 and the movable rod 70 abut against each other, the two claw teeth 1231 move toward each other, thereby firmly grasping the movable rod 70.

[0062] Of course, the movable component 1230 extending in the vertical direction in the present embodiment may also be extended in a direction forming an acute angle with the vertical direction and then fixed to the movable rod 70 , which will not be described in detail here.

[0063] Embodiment 3

[0064] Based on the first embodiment, this embodiment provides another structure and setting method of the movable parts. During the installation of the processing box, the movable parts will not squeeze the protrusion of the electronic imaging device and will not cause the protrusion to retract downward. In this embodiment, the top, bottom, left side, and right side of the processing box are all the directions when the processing box is installed inside the electronic imaging device, and the front and rear refer to the front and rear of the installation direction of the processing box to the electronic imaging device during the installation process. During the installation of the processing box, for example, it can be stipulated that the powder bin part is in the front and the waste powder bin part is in the back.

[0065] like Figure 12-16aAs shown, the processing box 20 includes a waste toner bin portion 300 and a powder bin portion 400. The waste toner bin portion 300 includes a photosensitive drum 320. The lower portion of the powder bin portion 400 includes a powder bin lower portion 420. The processing box 20 also includes a movable component 430, and the movable component 430 is movably connected to the powder bin portion 400. In some implementations, the movable component 430 is located on the processing box closer to the processing box lower portion than the powder bin lower portion 420, and at least a portion of the movable component 430 protrudes relative to the powder bin lower portion 420.

[0066] The powder bin portion 400 further includes a storage bin 440, and a portion of the movable component 430 is located in the storage bin 440. The powder bin portion 400 further includes a rotating portion 450. In this embodiment, the rotating portion 450 has an arc surface of a cylindrical outer circumference. The movable component 430 includes a rotatable portion 434. In this embodiment, the rotatable portion 434 has an arc surface of a cylindrical inner circumference, so that the rotatable portion 434 is entirely or partially surrounded by the outer surface of the rotating portion 450, so that the movable component 430 can rotate around the rotating portion 450, that is, the movable component 430 can be rotatably moved in the storage bin 440. In addition, the structures of the rotatable portion 434 and the rotating portion 450 are interchangeable.

[0067] In some embodiments, in this embodiment, a portion of the rotating portion 450 is connected to the powder bin portion 400, and the other portion is a cylindrical surface for the rotatable portion 434 to rotate around, and the rotatable portion 434 of the movable part 430 has an opening 434a, which is used to be mounted on the cylindrical surface of the rotating portion 450 in a snap-fitting manner to install and position the movable part 430.

[0068] In some embodiments, the movable component 430 further includes a resisting portion 433 , and the accommodating bin 440 includes an anti-detaching portion 441 , and the movable component 430 will not detach from the powder bin portion 400 through interference between the resisting portion 433 and the anti-detaching portion 441 .

[0069] In some embodiments, the process cartridge further comprises an elastic member 460 to constrain the movement of the movable member 430. In this embodiment, the elastic member 460 is a torsion spring, which is disposed in the powder bin portion 400, and provides a forced push constraint to the movable member 430 during the movement of the movable member 430, so as to help the movable member 430 to reset. In some embodiments, a positioning protrusion 470 is disposed in the powder bin portion 440, and the elastic member 460 is mounted on the positioning protrusion 470. In this embodiment, the elastic member 460 is located between the frame of the powder bin portion 400 and the movable member 430, so that one end of the elastic member 460 abuts against the movable member 430, and the other end abuts against the frame of the process cartridge. When the elastic member 460 is in a natural state, one end of the elastic member 460 can only overlap the movable member 430, and no force is applied to the movable member 430, or a force directed to the outside of the process cartridge is applied to the movable member 430. One end of the movable part 430 is sleeved on the rotating part 450 through the rotatable part 434, and the other end abuts on the anti-detachment part 441 through the abutting part 433 under the action of its own gravity or the elastic part 460. One end of the elastic part 460 in this embodiment abuts against the groove 435 of the movable part 430. As the movable part 430 rotates, one end of the elastic part 460 and the movable part 430 can adaptively move relative to each other, and under the limiting action of the two inner walls of the groove 435, the elastic part 460 is ensured not to be separated from the movable part 430, so as to provide stable constraints during the movement of the movable part 430.

[0070] The movable part 430 has a contact surface 431 that can contact the electronic imaging device. When the process box is installed into the electronic imaging device along the direction of arrow E and the process box is lowered along the direction of arrow F so that the contact surface 431 contacts the inside of the electronic imaging device, especially the protrusion inside the electronic imaging device, the movable part 430 will be retracted into the inside of the process box along the arrow M, that is, Fig.15 and Fig.15a In the state shown in , since there is a clearance fit between the movable part 430 and the powder bin part 400, the resistance to relative movement is small, and the gravity of the movable part 430 is small enough, or in the case where the elastic part 460 is provided, the thrust force exerted by the elastic part 460 on the movable part 430 is small enough, so that the movable part 430 will not press the protrusion downward, and the protrusion will not retract downward. At this time ( Fig.15 and Fig.15a The middle state is called the first position. In the first position, the movable part 430 retracts upward into the process box by rotating around the rotating part 450, and the blocking part 433 and the anti-detachment part 441 are free from interference. At this time, the elastic member 460 is in a deformed state due to the force of the movable part 430, and the reaction force (elastic restoring force) applied to the movable part 430 is a pushing force for returning the movable part 430 to its original position.

[0071] When the processing box is installed in place, the internal movement of the electronic imaging device causes the protrusion to move in the opposite direction of the processing box installation, and the protrusion leaves the position of abutting against the abutting surface 431 and moves to the side close to the pushing surface 432. At this time, since there is a clearance fit between the movable part 430 and the powder bin part 400 and the protrusion no longer abuts against the abutting surface 431, the movable part 430 is extended downward along the arrow N relative to the processing box by the action of gravity and the elastic restoring force of the elastic member 460 to achieve the reset action. At this time (after the movable part 430 is extended), the pushing surface 432 can contact the protrusion. At this time ( Fig.16 and Fig.16a ) is called the second position. Of course, when it is in the second position, the resisting portion 433 on the movable part 430 may not contact the anti-slip portion 441 because other components in the electronic imaging device abut against the movable part 430, or other components inside the processing box exert an effect on the movable part 430. Therefore, at the second position, the force applied by the elastic member 460 to the movable part 430 is reduced or until the elastic member 460 returns to the above-mentioned natural state. Compared with the first position, the movable part 430 is closer to the bottom of the processing box in the second position, and at least a part of the projection of the pushing surface 432 in the front or rear coincides with the projection of the protrusion in the front or rear (the overlap of one of the front or rear can be regarded as the projection overlap).

[0072] When the movable part is located in the second position and the electronic imaging device drives the protrusion to move along the processing box installation direction (direction of arrow E), the protrusion can exert force on the pushing surface 432 and push the powder bin part 400 to move relative to the waste powder bin part 300 and separate the roller drum.

[0073] In some embodiments, a locking portion 432a may be further provided on the pushing surface 432, and the locking portion 432a is positioned so as to be able to engage with the protrusion, wherein the specific structure of the locking portion 432a is not limited, and the locking portion 432a may be a groove structure or a protrusion structure, or may be a rough surface with a large friction coefficient, so as to limit the protrusion from slipping when force is applied on the pushing surface 432 as much as possible, so that when the protrusion applies force to the pushing surface 432, it can push the powder bin part 400 to move relative to the waste powder bin part 300, and it is not easy to slip out of the pushing surface 432.

[0074] This embodiment can ensure that the movable part 430 performs the moving action stably after each installation, and provides stable resetting of the movable part 430 and keeps the roller-drum separation during the moving process between the first position and the second position. In addition, compared with the first embodiment, when the movable part moves in the storage bin, there is friction on both sides, which may cause the swing of the movable part. In this embodiment, the movable part moves in the storage bin in a rotating form, which is more flexible and stable.

[0075] Embodiment 4

[0076] like Figure 17-19 As shown, based on the third embodiment, this embodiment provides another arrangement of the movable parts. The ends of the powder bin part 400 and the waste powder bin part 300 of the process box are connected via a protective cover 500, wherein an end cover 480 is arranged on the end of the powder bin part 400, the movable part 430 and the elastic member 460 in this embodiment are arranged on the end cover 480, and the protective cover 500 is arranged on the outside of the end cover 480.

[0077] like Fig.18 and Fig.19 As shown, the end cover 480 includes an inner wall 482 facing the inner side of the processing box, and the end cover 480 is provided with a receiving chamber 440, a rotating portion 450, and an anti-detachment portion 441, all of which can be formed by extending from the inner wall 482. A part of the movable component 430 is located in the receiving chamber 440. Through the cooperation of the rotatable portion 434 and the rotating portion 450, the movable component 430 can be rotatably moved in the receiving chamber 440, and through the interference between the abutment portion 433 and the anti-detachment portion 441, the movable component 430 will not be separated from the end cover 480. The end cover 480 is also provided with a positioning protrusion 470, and the elastic member 460 is installed on the positioning protrusion 470. The first end 460a of the elastic member 460 abuts on the movable component 430, and the second end 460b abuts on the frame 481.

[0078] In some embodiments, a first end wall 442 and a second end wall 443 are further provided on the end cover 480, so that the movable component 430 is located between the first end wall 442 and the inner wall 482, and the second end 460b of the elastic member 460 is located between the second end wall 443 and the inner wall 482, so as to prevent the movable component 430 and the elastic member 460 from falling off from the end cover 480 during the activity.

[0079] According to this embodiment, it is conceivable that the movable component 430 can be set not only on the end cover 480, but also on the protective cover 500 or on the waste powder bin part 300, as long as the movable component 430 can transmit the thrust force provided by the electronic imaging device shown to the powder bin part 400 of the processing box, so that relative movement occurs between the powder bin part 400 and the waste powder bin part 300.

[0080] Embodiment 5

[0081] like Fig. 20As shown, based on the first embodiment, this embodiment provides another arrangement of the movable part. The processing box also includes an elastic member 260, which is located between the frame of the powder bin part 200 and the movable part 230, and provides a forced push constraint to the movable part 230 during the movement of the movable part 230 to help the movable part 230 to reset. In this embodiment, the elastic member 260 is arranged in the accommodating bin 240, and one end of the elastic member 260 abuts on the movable part 230, and the other end abuts on the frame of the processing box. When the elastic member 260 is in a natural state, one end thereof may only touch the movable part 230, and no force is applied to the movable part 230 or a force directed to the outside of the processing box is applied to the movable part 230. In some embodiments, the elastic member 260 is a sponge, and is respectively arranged to abut on the two abutting portions 233 of the movable part 230.

[0082] When the processing box is installed in the electronic imaging device, when the contact surface 231 of the movable part 230 contacts the inside of the electronic imaging device, especially the protrusion inside the electronic imaging device, the movable part 230 is retracted into the inside of the processing box. Since the movable part 230 and the powder bin part 200 are clearance-matched, the resistance generated by the relative movement is small, and the gravity of the movable part 230 is small enough. In the case where the elastic part 260 is provided, the thrust force applied by the elastic part 260 on the movable part 230 is small enough, so that the movable part 230 will not press the protrusion downward, and the protrusion will not be retracted downward. At this time, the movable part 230 is in the first position.

[0083] When the processing box is installed in place, the internal movement of the electronic imaging device causes the protrusion to move in the opposite direction of the processing box installation, and the protrusion leaves the position abutting against the abutting surface 231 and moves to the side close to the pushing surface 232. At this time, since there is a clearance fit between the movable part 230 and the powder bin part 200 and the protrusion no longer abuts against the abutting surface 231, the movable part 230 is extended downward relative to the processing box by the action of gravity and the elastic restoring force of the elastic member 260 to achieve the reset action. At this time, the movable part 230 is in the second position. At the second position, the force applied by the elastic member 260 to the movable part 230 is reduced or until the elastic member 260 returns to the above-mentioned natural state.

[0084] When the movable component is located at the second position and the electronic imaging device drives the protrusion to move along the processing box installation direction, the protrusion can exert a force on the pushing surface 232 and push the powder bin part to move relative to the waste powder bin part and separate the roller drum.

[0085] In addition, if Fig.21 As shown, an optimized structure of the elastic member 260 is provided. The elastic member 260 may be an integral sponge, which is located in the accommodating chamber 240 and directly abuts against the two abutting portions 233 of the movable component 230 .

[0086] The remaining structures are the same as those of the first embodiment. This embodiment can ensure that the movable component 230 is stably executed in its movable action after each installation, and provides stable resetting for the movable component 230 during the movement between the first position and the second position.

[0087] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
