[0252] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings.

[0253] like Figure 1As shown, the electronic photographic imaging device includes an imaging device body (not shown) and a developing cartridge 200 detachably mounted to the imaging device body. The imaging device body includes a communication port provided on the outer surface, and when the developing cartridge 200 is mounted to the imaging device, a toner replenishment inlet 201 of the developing cartridge 200 is connected to the communication port of the imaging device body, and a user can replenish toner (i.e., developer) to the developing cartridge 200 through the communication port.

[0254] Embodiment 1

[0255] like Figures 2 to 4 As shown, the powder adding box 100 of this embodiment includes a main body 1 and a pushing member 2, wherein the main body 1 includes a developer discharge portion 14 and a developer chamber 111. In this embodiment, the main body 1 is a cylindrical hollow cylinder, and the hollow portion constitutes a developer chamber 111 for accommodating a developer (such as toner), and the upper end of the developer chamber 111 is open. The developer discharge portion 14 of the powder adding box 100 is located at the lower end of the main body 1, and includes a developer outlet 113, and the toner is discharged from the outside of the main body 1 through the developer outlet 113.

[0256] The pushing member 2 is used to push the toner and can move in the longitudinal direction Z of the main body 1 toward the developer outlet 113, so that the toner contained in the main body 1 is discharged from the developer outlet 113 of the developer discharge portion 14. In this embodiment, the pushing member 2 is inserted into the main body 1 from the upper end of the main body 1 and can move relative to the main body 1. The pushing member 2 includes a first rod portion 21, a pressing portion 22 located at the upper end of the first rod portion 21, and a piston portion 23 located at the lower end of the first rod portion 21. The first rod portion 21 is generally a hollow cylinder, and has a hollow chamber 213 inside. The first rod portion 21 includes a first through groove 212 extending along the longitudinal direction Z of the main body on its circumferential side wall, and the length of the first through groove 212 is greater than the distance from the lower end of the pushing member 2 to the developer outlet 113. In this embodiment, the circumferential outer wall of the first rod portion 21 is provided with a plurality of first through grooves 212, and the plurality of first through grooves 212 are arranged at intervals along the circumferential outer wall of the first rod portion 21. The pressing portion 22 is in a flat rectangular parallelepiped shape, and the upper end of the first rod portion 21 is fixedly connected to the pressing portion 22. The piston portion 23 is installed on the circumferential outer wall of the lower end of the first rod portion 21, and the piston portion 23 is sealed and connected to the main body 1 and can slide along the inner wall of the main body 1. When the pushing member 2 moves in the longitudinal direction Z of the main body 1 toward the developer outlet 113, the toner contained in the main body 1 is discharged from the developer outlet 113 under the pushing of the pushing member 2.

[0257] like Figure 3 and Figure 4As shown, the powder box 100 also includes a locking device 103 for locking the pushing member 2, a covering member 104, a first fixing member 105 and a force-applying member 106. The locking device 103 includes a first hole 1031, a second hole 1032 and a moving member 1033, wherein the first hole 1031 is arranged on the circumferential wall of the upper end of the main body 1 and is a circular hole that penetrates the circumferential wall of the main body 1. The second hole 1032 is a hole with the same diameter as the first hole 1031, which is arranged on the circumferential wall of the lower end of the first rod 21 and faces the first hole 1031. In this embodiment, the moving member 1033 is cylindrical, and the outer diameter of the moving member 1033 is the same as or slightly smaller than the inner diameter of the first hole 1031 and the second hole 1032, and its axial length is greater than the axial length of the first hole 1031. The moving part 1033 is inserted into the first hole 1031 and the second hole 1032 to lock the pushing member 2, that is, the pushing member 2 is locked in the longitudinal direction Z of the main body 1 and cannot move. Figure 4 As shown, the movable part 1033 is in the locked position. In the present embodiment, a hook-shaped pulling portion 1034 is also provided at one end of the movable part 1033, and the user can pull or push the movable part 1033 to move through the pulling portion 1034. Optionally, the movable part 1033 can also be other shapes and structures, such as flat, prismatic, etc., and there is no strict restriction on its shape, as long as it can play the role of locking the pushing member 2, and the corresponding shapes of the first hole 1031 and the second hole 1032 can also correspond to the structure of the movable part 1033. In addition, the first hole 1031 can also be eliminated, and the movable part 1033 is inserted into the second hole 1032 and abuts against the upper end surface 24 of the main body 1. Optionally, the second hole 1032 can also be eliminated, for example, a protrusion is provided on the circumferential outer wall of the first rod portion 21 to cooperate with the movable part 1033 to achieve the same technical effect.

[0258] The cover 104 is a hollow columnar body, which can be detachably mounted on the outside of the moving part 1033 to cover the moving part 1033 . The setting of the cover 104 can protect the moving part 1033 to prevent the powder box user from accidentally touching the moving part 1033 .

[0259] The first fixing member 105 includes a disc-shaped fixing portion 1051 and a plurality of first arm portions 1052 extending outward from the circumferential side wall of the fixing portion 1051. The plurality of first arm portions 1052 are arranged at intervals along the circumferential outer wall of the fixing portion 1051. Figure 4As shown, the fixing portion 1051 is located in the hollow chamber 213 of the first rod portion 21, and the multiple first arm portions 1052 correspond to the multiple first through grooves 212 of the first rod portion 21. The first arm portion 1052 passes through the first through grooves 212 to form a fixed connection with the inner wall of the main body 1. The first rod portion 21 can move in the longitudinal direction Z of the main body 1 relative to the first arm portion 1052. The setting of the first through groove 212 can prevent the pushing member 2 from interfering with the first fixing member 105 during the movement along the longitudinal direction Z of the main body.

[0260] The force-applying component 106 is used to apply a force to the pushing member 2 to move the pushing member 2 in a direction close to the developer outlet 113. When the locking device 103 releases the lock on the pushing member 2, the pushing member 2 moves in a direction close to the developer outlet 113, thereby causing the toner (i.e., developer) to be discharged from the developer outlet 113 of the main body 1. In this embodiment, the force-applying component 106 is a first elastic member, specifically a tension spring. The force-applying component 106 is located in the hollow chamber 213 of the first rod portion 21, one end of which is connected to the first hook portion 1053 located in the middle of the fixing portion 1051, and the other end is connected to the second hook portion 221 located in the middle of the pressing portion 22, so that the force-applying component 106 is in a stretched state and has an elastic pulling force on the pushing member 2. The force-applying component of the present invention can also be other first elastic members, such as an elastic arm, a compression spring, etc.

[0261] A new toner cartridge, before adding toner, Figure 4 As shown, since the moving part 1033 of the locking device 103 is inserted into the first hole 1031 and the second hole 1032, the moving part 1033 is in the locked position, and the pushing member 2 is pressed against the moving part 1033. The pushing member 2 is blocked by the moving part 1033 and is in a locked state, and cannot move along the longitudinal direction Z of the main body 1. Figure 1 When adding powder, the user can insert the developer discharge portion 14 of the powder adding box 100 into the communication port of the imaging device, rotate the powder adding box 100 so that the developer outlet 113 of the powder adding box 100 is connected with the toner replenishment inlet 201 of the developer box 200 in the imaging device, and after removing the cover 104, the user pulls the moving part 1033 to the unlocking position, such as Figure 5 The position of the movable component 1033 is shown. In the unlocked position, the movable component 1033 is disengaged from the second hole 1032, and the pushing member 2 is not blocked by the movable component 1033. Under the action of the elastic restoring force of the tension spring 106, the pushing member 2 moves along the longitudinal Z direction of the main body 1 towards the developer outlet 113, and the toner is discharged from the developer outlet 113 of the developer discharge portion 14 until the lower end of the pushing member 2 contacts the inner wall of the lower end of the main body 1, and the powder adding operation is completed.

[0262] The powder adding box of the above structure does not require the user to press the pushing member 2. The user only needs to pull the moving part 1033 of the locking device 103 to move the moving part 1033 from the locked position to the unlocked position. The pushing member 2 can automatically add powder under the elastic restoring force of the tension spring 106.

[0263] Embodiment 2

[0264] like Figures 6 to 9 As shown, this embodiment provides a powder box 100. Different from the above-mentioned embodiment 1, the locking device 103 also includes a first pushing portion 1035 and a reset member 1036. The first pushing portion 1035 and the reset member 1036 are arranged in the first hole 1031. The first pushing portion 1035 can push the movable part 1033 from the locked position (that is, the movable part 1033 is in the first hole 1031 and the second hole 1032) to the unlocked position (that is, the movable part 1033 is pushed by the first pushing portion 1035 to move to the second hole 1032 to release the lock of the pushing member 2) under the action of external force. Specifically, the first pushing portion 1035 can be two connected cylinders, and the diameters of the two cylinders are different, wherein the diameter of the cylinder away from the moving part 1033 is larger than the diameter of the cylinder close to the moving part 1033, and the diameter of the cylinder away from the moving part 1033 is equal to or slightly smaller than the inner diameter of the first hole 1031, and the reset member 1036 is sleeved on the outer side of the cylinder of the first pushing portion 1035 close to the moving part 1033, and the reset member 1036 is limited to move between the inner end face of the cylinder away from the moving part 1033 and the bottom of the first hole 1031. When the reset member 1036 is not subjected to external force, the first pushing portion 1035 is maintained at a position away from the movable component 1033. When the user applies external force to press the first pushing portion 1035, the first pushing portion 1035 moves in a direction close to the movable component 1033, pushing the movable component 1033 into the second hole 1032, releasing the lock on the pushing member 2, and the powder adding box 100 performs the powder adding operation. At the same time, during the movement of the first pushing portion 1035, the reset member 1036 is compressed, generating a force acting on the first pushing portion 1035 in the opposite direction of the pushing direction of the first pushing portion 1035; when the user no longer applies a force to press the first pushing portion 1035 or the force is not sufficient to offset the elastic force generated by the reset member 1036, the reset member 1036 begins to recover, causing the first pushing portion 1035 to start moving away from the main body 1, thereby resetting the first pushing portion 1035. Specifically, the reset member 1036 may be a second elastic member, such as a compression spring, a spring sheet, an elastic sponge, an elastic rubber, etc.

[0265] Optionally, the first pushing portion 1035 may also be a structure of other shapes, such as flat, prismatic, etc. There is no strict limitation on its shape as long as it can push the movable part 1033 to move. The corresponding shapes of the first hole 1031, the second hole 1032 and the movable part 1033 may also correspond to the structure of the first pushing portion 1035.

[0266] Embodiment 3

[0267] like Figure 10 to Figure 11 As shown, this embodiment provides a powder adding box 100, which is different from the above-mentioned embodiment 2 in that a force-applying component 106 is arranged on the circumferential outer wall of the main body 1. Specifically, at least two first connecting parts 15 are evenly arranged on the circumferential outer wall of the main body 1, a second connecting part 221 corresponding to the first connecting part 15 is arranged on the pressing part 22, a third hook 151 is arranged on the first connecting part 15, and a fourth hook 2211 is arranged on the second connecting part 221. The number of force-applying components 106 is the same as the number of the first connecting parts 15 and the second connecting parts 221, and one end of the force-applying component 106 is connected to the third hook 151 on the first connecting part 15, and the other end is connected to the fourth hook 2211 on the second connecting part 221, so that the force-applying component 106 is in a stretched state and has an elastic pulling force on the pushing member 2. Specifically, the first connection portion 15 and the second connection portion 221 may be raised portions, and the raised portions may be in the shape of a cuboid, a cube, a prism, a pyramid, etc. There is no strict limitation on the shape, as long as the corresponding third hook portion 151 and fourth hook portion 2211 can be provided.

[0268] Optionally, the number of force-applying components 106, the first connecting portion 15 and the second connecting portion 221 can be set according to the actual size of the powder box 100. For a smaller powder box 100, two are sufficient. For a larger powder box 100, the number of force-applying components 106, the first connecting portion 15 and the second connecting portion 221 can be increased, such as 3-6, and evenly distributed on the circumferential outer wall of the main body 1 and the pressing portion 22.

[0269] Optionally, the locking device 103 may adopt the structure as in the first embodiment.

[0270] Embodiment 4

[0271] like Figures 12 to 15As shown, this embodiment provides a powder adding box 100. Different from the above-mentioned second embodiment, the pushing member 2 in this embodiment includes a piston portion 23, and the first rod portion 21, the first through groove 212, and the hollow chamber 213 are omitted. In this embodiment, the upper end of the main body 1 is provided with a first fixing member 105, and at least two engaging portions 1054 are evenly arranged at the bottom of the first fixing member 105. The upper circumferential wall of the main body 1 is provided with a first combining portion 16 that matches the engaging portion 1054. Specifically, the engaging portion 1054 can be a hook, and the first combining portion 16 can be a hole. The hook is inserted into the corresponding hole to install the first fixing member 105 on the upper end of the main body 1, and the piston portion 23 is arranged inside the main body 1. One end of the force-applying component 106 is connected to the first fixing member 105, and the other end is connected to the piston portion 23. Specifically, the force-applying component 106 in this embodiment is a first elastic member, which can be a compression spring. When the piston portion 23 is locked by the locking device 103, the force-applying component 106 is in a compressed state. When the locking device 103 is unlocked, the force-applying component 106 begins to recover and pushes the piston portion 23 to move in a direction close to the developer outlet 113. The first fixing member 105 and the middle of the piston portion 23 can be provided with a flange portion for fixing the compression spring 106.

[0272] Optionally, the engaging portion 1054 may also be a locking hole, and the first coupling portion 16 may be a corresponding hook, which can also achieve the effect of installing the first fixing member 105 on the upper end of the main body 1 .

[0273] Optionally, the number of the snap-fitting portions 1054 and the first combining portions 16 can be set according to the actual size of the powder box 100. For a smaller powder box 100, two snap-fitting portions 1054 and the first combining portions 16 can be set. For a larger powder box 100, the number of the snap-fitting portions 1054 and the first combining portions 16 can be increased, such as 3-4, which are evenly distributed on the circumferential outer wall of the main body 1 at the bottom of the first fixing member 105.

[0274] Optionally, the engaging portion 1054 can be configured as a protrusion of other shapes, and the shape of the protrusion is not strictly limited. The first coupling portion 16 can be configured as a card hole or a card slot of a corresponding shape, into which the protrusion can be inserted.

[0275] Optionally, the locking device 103 may adopt the structure as in the first or second embodiment.

[0276] Compared with the above-mentioned embodiments, the pushing member 2 of this embodiment saves more space, reduces the volume of the entire powder adding box, is conducive to the miniaturization of the powder adding box, and reduces the cost of packaging and transportation.

[0277] Embodiment 5

[0278] The existing powder adding box has a rubber sleeve at the end of the piston rod that is sealed with the inner wall of the cylinder of the powder adding box, which causes the user to need a lot of force to add the toner when adding powder, and also requires a lot of force when pulling out the piston rod; in addition, when the cylinder is full of toner, the user needs more force to add the toner into the printer. The powder adding box of this structure is not conducive to the user to control the pressing and pulling speed, and cannot be pressed stably, and the powder adding effect is not good. In order to solve these problems, this embodiment provides a powder adding box.

[0279] like Fig.16 As shown, the powder adding box of this embodiment includes a main body 1 and a pushing member 2. The difference from the above embodiment is that Figures 16 to 18 As shown, the pushing member 2 includes a first rod portion 21 and a second fixing member 4. In this embodiment, the second fixing member 4 is an upper end cover 4 that closes the open end of the main body 1, and the upper end cover 4 is sealed and connected to the main body 1. The second fixing member 4 is cylindrical, including a cylindrical main body 41 and a cap 42 arranged at the upper end of the circumferential outer wall of the main body 41. The circumferential outer wall of the main body 41 is adapted to the circumferential inner wall of the main body 1, that is, the outer diameter of the main body 41 is equal to or slightly smaller than the inner diameter of the main body 1, so that the main body 41 can be inserted into the main body 1. The cap 42 is provided with an annular groove that matches the upper end of the main body 1, so that the upper end cover 4 can be fixedly sleeved on the upper end of the main body 1 through the annular groove. A circular through hole 43 is provided in the center of the main body 41, and a groove 44 is provided on the circumferential inner wall of the circular through hole 43. The groove 44 extends along the circumferential inner wall of the circular through hole 43 in a spiral shape. Optionally, the length of the groove 44 may also be smaller than the circumference of the circular through hole 43 .

[0280] like Figures 16 to 19 As shown, in this embodiment, a pressing portion 22 is provided at the upper end of the first rod portion 21, and the pressing portion 22 is in the shape of a disk. The first rod portion 21 is in the shape of a cylinder, and its outer diameter is smaller than the inner diameter of the main body 1 and the inner diameter of the circular through hole 43 of the upper end cover 4. The upper end of the first rod portion 21 is fixedly connected to the center of the pressing portion 22, and the circumferential outer diameter of the pressing portion 22 is larger than the inner diameter of the main body 1 and the inner diameter of the circular through hole 43 of the upper end cover 4. A convex rib 221 is provided on the circumferential outer wall of the first rod portion 21, and the convex rib 221 extends around the circumferential outer wall of the first rod portion 21 in a spiral shape. The convex rib 221 and the groove 44 on the circumferential inner wall of the circular through hole 43 are adapted to each other, that is, by rotating the first rod portion 21, the spiral convex rib 221 on the first rod portion 21 can cooperate with the groove 44, so that the first rod portion 21 moves in the axial direction A of the main body 1 (that is, the longitudinal direction of the main body). In this embodiment, the longitudinal direction of the main body, the rotation direction of the first rod portion 21 and the axial direction of the circular through hole are parallel.

[0281] like Fig.19As shown, a part of the convex rib 221 of the first rod portion 21 is located in the groove 44. When the main body 1 is filled with toner, the pressing portion 22 is rotated to drive the first rod portion 21 to rotate. The spiral convex rib 221 on the circumferential outer wall of the first rod portion 21 cooperates with the spiral groove 44 on the circumferential inner wall of the upper end cover 4. As the first rod portion 21 rotates, the first rod portion 21 gradually moves toward the inside of the main body 1, that is, along the axial direction A of the main body 1 toward the direction close to the developer outlet 113 of the main body 1. The lower end of the first rod portion 21 pushes the toner, so that the toner is gradually discharged from the developer outlet 113 of the main body 1. Of course, a piston portion (not shown in the figure) can be set at the lower end of the first rod portion 21. The piston portion can be a plate-like member. The piston portion is movably connected to the first rod portion 21, that is, the first rod portion 21 can rotate relative to the piston portion, and the first rod portion 21 can push the piston portion to move. Since the piston portion is sealed with the inner wall of the main body 1, the toner can be pushed more fully so that the toner is discharged from the developer outlet 113 of the main body 1.

[0282] The toner box is provided with convex ribs and grooves, and the toner in the main body is gradually pushed by rotating the first rod part. The toner is pushed stably, the speed is controllable, and the user's effort can be greatly reduced.

[0283] In this embodiment, the second fixing member is configured as the upper end cover of the main body, which is only a preferred method. The second fixing member can also be set in the main body or other positions fixedly connected to the main body. The spiral convex rib is provided on the circumferential outer wall of the first rod portion, and the cooperation with the spiral groove on the circumferential inner wall of the circular through hole of the upper end cover (second fixing member) of the main body is only a preferred method. The thread groove can also be provided on the circumferential outer wall of the first rod portion, and the convex rib (which can be a small section) or protrusion that cooperates with the thread groove can be provided on the circumferential inner wall of the circular through hole; of course, it is also possible to provide a thread (equivalent to the convex rib) on one of the first rod portion and the second fixing member, and provide a thread groove on the other; as long as the first rod portion can move along its rotation axis when the first rod portion is rotated.

[0284] Embodiment 6

[0285] When the existing powder adding box is not used for a long time, the gaps between the toner particles in the toner box will become smaller due to the long-term storage, and even agglomeration will occur, which is not conducive to the discharge of the toner. In order to solve these problems, this embodiment provides a powder adding box.

[0286] like Figure 20 to Figure 23As shown, the powder adding box 100 of this embodiment includes a main body 1, a pushing member 2 and a stirring device 102. Different from the above embodiment, in this embodiment, the main body 1 includes an inner cylinder 11, an outer cylinder 12, an upper end cover 13 and a developer discharge portion 14. The inner cylinder 11 and the outer cylinder 12 are fixedly connected and are both cylindrical hollow cylinders. The inner cylinder 11 is a hollow part that constitutes a developer chamber 111 (such as a developer chamber) for accommodating a developer (such as toner). Fig.23 The outer tube 12 is shown in the figure, the upper end of which is open, and the lower end is provided with a first powder outlet 113 (equivalent to the developer outlet in the first embodiment). The upper end of the outer tube 12 is open, and the lower end is provided with a second powder outlet. When adding powder, the first powder outlet 113 and the second powder outlet can be connected, and the carbon powder is discharged from the outside of the main body 1 through the first powder outlet 113 and the second powder outlet.

[0287] In this embodiment, the developer discharge portion 14 of the powder box 100 is located at the lower end of the main body 1, including a first powder outlet 113 and a second powder outlet. The first powder outlet 113 and the second powder outlet can be arranged in the center or offset from the middle axis of the main body 1. The upper end cover 13 is sealed and connected to the outer cylinder 12. The upper end cover 13 is roughly cylindrical, and a first through hole 131 is arranged at the center of its end face. The upper end cover 13 in this embodiment is equivalent to the second fixing member 4 / upper end cover 4 in the fifth embodiment, and can also be used for sealing the upper end of the main body 1, eliminating the spiral groove structure of the circumferential inner wall of the upper end cover in the fifth embodiment.

[0288] The pushing member 2 is used to push the toner. When the pushing member 2 moves in the longitudinal direction Z of the main body 1 toward the developer discharge portion 14, the toner contained in the main body 1 is discharged from the developer discharge portion 14. In this embodiment, the pushing member 2 includes a first rod portion 21 and a piston portion 23. The first rod portion 21 passes through the first through hole 131 of the upper end cover 13 and the lower end is inserted into the inner cylinder 11. The upper end of the first rod portion 21 is provided with a pressing portion 22. In this embodiment, the first rod portion 21 is cylindrical, passes through the circular first through hole 131 and is inserted into the inner cylinder 11, and can move relative to the main body 1. The pressing portion 22 is disc-shaped, and the upper end of the first rod portion 21 is fixedly connected to the center of the pressing portion 22. The outer diameter of the circumference of the pressing portion 22 is greater than the inner diameter of the outer cylinder 12 and the inner diameter of the circular first through hole 131 of the upper end cover 13. The piston portion 23 is sleeved on the outer wall of the lower circumference of the first rod portion 21 and is located between the first rod portion 21 and the inner wall of the inner cylinder 11. The piston portion 23 is sealed and connected to the inner cylinder 11 and can slide along the inner wall of the inner cylinder 11. When the first rod portion 21 moves in the longitudinal direction Z of the main body toward the developer discharge portion 14, the toner contained in the inner cylinder 11 is discharged from the developer discharge portion 14.

[0289] like Fig.21 and Fig. 22As shown, the powder adding box 100 in this embodiment also includes a stirring device 102 for stirring the carbon powder contained in the inner cylinder 11, and the stirring device 102 includes a transmission shaft, a stirring part 1022 and a first through hole 1023 matching the transmission shaft. In this embodiment, the transmission shaft is a spiral rod 1021, and the spiral rod 1021 is located inside the inner cylinder 11 and its length is less than the length of the inner cylinder 11. The first through hole 1023 is arranged on the lower end surface of the first rod portion 21, and is an 8-shaped hole, that is, when viewed along the longitudinal direction Z of the main body, the first through hole 1023 is roughly 8-shaped, one end of the spiral rod 1021 is inserted into the first through hole 1023 to form a movable connection with the first rod portion 21, and the first through hole 1023 is adapted to the spiral rod 1021, so that the spiral rod 1021 moves linearly relative to the first through hole 1023, and rotates in cooperation with the first through hole 1023. The first rod portion 21 is provided with a receiving chamber 1024 (equivalent to the hollow chamber 213 in the first embodiment) connected to the first through hole 1023. The receiving chamber 1024 extends along the length direction of the first rod portion 21 and has a length greater than or equal to the length of the spiral rod 1021, and can receive the spiral rod 1021. The spiral rod 1021 can be made of plastic material or metal material.

[0290] In this embodiment, the stirring portion 1022 is disposed at the lower end of the spiral rod 1021 in the length direction and is fixedly connected to the spiral rod 1021. Of course, it can also be configured to be detachable from the spiral rod 1021. The stirring portion 1022 is located at one end of the inner cylinder 11 close to the developer discharge portion 14. In this embodiment, the stirring portion 1022 includes a fixed block 1025 fixedly connected to the spiral rod 1021 and a stirring blade 1026. The fixed block 1025 is roughly conical in shape, and a circular ring 1027 is disposed on the outer side of the fixed block 1025. The stirring blade 1026 is in the form of a sheet and has a plurality of them. The stirring blade 1026 is connected between the fixed block 1025 and the circular ring 1027. The plurality of stirring blades 1026 are spaced apart along the circumferential direction of the fixed block 1025. The stirring blade 1026 and the upper end surface of the fixed block 1025 are at a preset angle, that is, the stirring blade 1026 extends from the circumferential side wall of the fixed block 1025 obliquely upward and away from the direction of the rotation axis of the stirring blade 1026. The stirring portion 1022 of this structure is conducive to stirring the powder, making the stirring more sufficient. The stirring blade 1026 can also be arranged to extend obliquely downward, and the material of the stirring blade 1026 can be plastic, as long as it can be used to stir carbon powder. In this embodiment, a plurality of protrusions 1028 are arranged at intervals along the circumference of the circular ring 1027 on one end surface away from the first rod portion 21, and the protrusions 1028 can abut against the bottom wall 112 at the first powder outlet 113 of the inner cylinder 11, so that the stirring blade 1026 and the fixing block 1025 are separated from the first powder outlet 113, so as to prevent the fixing block 1025 or the stirring blade 1026 from blocking the first powder outlet 113 of the inner cylinder 11 and causing carbon powder to be blocked. Regardless of whether the powder outlet is set at the middle position of the lower end of the inner cylinder 11 or deviates from the middle position, the setting of the protrusions 1028 can prevent the stirring device from blocking the powder outlet.

[0291] like Figure 21 to Figure 23 As shown, during the powder adding operation, the developer discharge portion 14 of the powder adding box 100 is inserted into the communication port of the imaging device, and the user presses the pressing portion 22 at the upper end of the first rod portion 21 to move the first rod portion 21 in the longitudinal direction Z of the main body toward the developer discharge portion 14. During the movement of the first rod portion 21, the protruding portion 1028 of the stirring portion 1022 presses against the bottom wall 112 at the lower end side of the inner cylinder 11. Fig.21 and Fig.23 The first through hole 1023 moves along the spiral rod 1021 toward the first powder outlet 113, and the spiral rod 1021 gradually enters the accommodating chamber 1024. The spiral rod 1021 moves linearly relative to the first through hole 1023 and rotates with the cooperation of the first through hole 1023 (its principle is similar to that of the existing toy hand-pushed flying saucer). The stirring part 1022 rotates under the rotation of the spiral rod 1021, thereby stirring the toner in the developer chamber 111 of the inner cylinder 11.

[0292] The stirring device 102 of this structure can stir the carbon powder during the process of pushing the first rod portion 21 to add powder, thereby increasing the gap between carbon powder particles, increasing the discharge rate of carbon powder, and avoiding clogging of the powder outlet due to carbon powder agglomeration and the like.

[0293] In this embodiment, providing the stirring portion 1022 at the lower end of the spiral rod 1021 is only a preferred solution. The stirring portion 1022 may also be eliminated, and the spiral rod 1021 itself may also achieve stirring of the carbon powder.

[0294] Embodiment 7

[0295] like Figures 24 to 27 As shown, the powder adding box 100 of this embodiment includes a main body 1, a pushing member 2 and a stirring device 102. Different from the above-mentioned embodiment 6, the stirring device 102 in this embodiment further includes a pulling member 1029. In this embodiment, a second through hole (not shown in the figure) communicating with the outside of the powder adding box 100 is provided in the middle position of the upper end (that is, the pressing portion 22) of the accommodating chamber 1024 of the first rod portion 21, and the pulling member 1029 can pass through the second through hole (not shown in the figure) to connect with the spiral rod 1021, that is, the pulling member 1029 passes through the middle of the pressing portion 22 into the accommodating chamber 1024 and connects with the spiral rod 1021.

[0296] The pulling member 1029 passes through the second through hole from the outside and is connected to the upper end of the spiral rod 1021, and is indirectly connected to the stirring part 1022, so that the stirring part 1022 can be driven to move when the pulling member 1029 is pulled. The pulling member is in the shape of an elongated strip and is made of a flexible material, and its length is longer than the length of the first rod part 21, so that at least a part of the pulling member is located outside the powder box 100, which is convenient for the user to pull. In this embodiment, the pulling member 1029 is a flexible rope, and a pulling part is also provided at one end of the pulling member 1029 located outside the powder box 100. In this embodiment, the pulling part is a pull ring 1029a, which is arranged outside the first rod part 21, which is convenient for the user to pull. Optionally, the pulling part can also be other shapes and structures, as long as it is convenient for the user to pull.

[0297] Optionally, the spiral rod 1021 can be eliminated, and one end of the pulling member 1029 passes through the first through hole 1023 and is directly connected to the stirring part 1022, while the other end is exposed outside the powder adding box. When the pulling member 1029 is pulled, the stirring part 1022 moves along the longitudinal direction of the main body. The stirring part 1022 does not rotate, and only the longitudinal movement can achieve the effect of stirring the carbon powder.

[0298] Optionally, the pulling member 1029 may also be made of a hard material (such as a hard push rod) so that the stirring portion 1022 can be moved up and down by pulling and pushing the pulling member 1022, thereby stirring the carbon powder in the main body 1 multiple times for more complete stirring.

[0299] like Figure 25 to Figure 27 As shown, Fig.26 The state diagram of the stirring device 102 before the stirring operation is shown. Fig. 27 The state diagram of the stirring device 102 after the pulling member 1029 is pulled is shown. Before the powder adding operation, the user can hook the pull ring 1029a of the pulling member 1029 and pull it outwards. The spiral rod 1021 moves in the longitudinal direction Z of the main body 1 away from the first powder outlet 113 under the pulling of the pulling member 1029. The spiral rod 1021 gradually enters the accommodating chamber 1024 and the spiral rod 1021 moves linearly relative to the first through hole 1023 and rotates under the cooperation of the first through hole 1023 (its principle is similar to that of the existing toy hand-pushed flying saucer). The stirring part 1022 rotates under the drive of the spiral rod 1021, so that the edge in the developer chamber 111 of the inner cylinder 11 points to the direction away from the first powder outlet 113 while rotating, so that the carbon powder in the developer chamber 111 is fully stirred, and the stirring effect is good and easy to control. After the stirring operation, the user can insert the developer discharge portion 14 of the powder adding box 100 into the connecting port of the imaging device, press the pressing portion 22 at the upper end of the first rod portion 21 to move the first rod portion 21 along the longitudinal direction Z of the main body, and the toner is discharged from the developer discharge portion 14 into the imaging device to complete the powder adding.

[0300] With the powder adding box having the above structure, even if the user forgets to pull the pulling member 1029 to loosen the powder before adding powder and directly presses the first rod portion 21, the stirring device 102 can still play the role of stirring the carbon powder. Specifically, the user presses the pressing portion 22 at the upper end of the first rod portion 21 to move the first rod portion 21 along the longitudinal direction Z of the main body. During the movement of the first rod portion 21, the protrusion of the stirring portion 1022 presses against the bottom wall 112 on the lower end side of the inner cylinder 11, and the first through hole 1023 moves along the spiral rod 1021 toward the first powder outlet 113, and the spiral rod 1021 gradually enters the accommodating chamber 1024. While the spiral rod 1021 moves linearly relative to the first through hole 1023, it rotates under the cooperation of the first through hole 1023 (its principle is similar to that of the existing toy hand-pushed flying saucer), and the stirring portion 1022 rotates driven by the spiral rod 1021, thereby stirring the carbon powder in the developer chamber 111 of the inner cylinder 11.

[0301] The stirring device 102 of this structure can fully stir the carbon powder when pulling the pulling member 1029, and can also stir the carbon powder when directly pushing the first rod portion 21. The setting of the stirring device 102 can fully stir the carbon powder in the powder box, increase the gap between the carbon powder particles, increase the carbon powder discharge rate, and avoid clogging the powder outlet due to carbon powder agglomeration and the like.

[0302] In this embodiment, the stirring part 1022 is provided at the lower end of the spiral rod 1021, which is only a preferred solution. The stirring part 1022 can also be eliminated, and the spiral rod 1021 itself can also stir the carbon powder. The pulling member is made of a flexible material, which is only a preferred rotation. The pulling member can also be made of a hard material, such as a slender push rod instead of the flexible rope in this embodiment. The push rod is used as a pulling member to pull the spiral rod and push the spiral rod, so that the spiral rod can move back and forth, and the carbon powder in the powder box can be stirred multiple times, so that the carbon powder is stirred more fully.

[0303] Embodiment 8

[0304] There is an existing powder adding box, which includes a cylinder and a piston rod that can move along the longitudinal direction of the cylinder. The piston rod is provided with a sleeve for fixing the piston rod. Before performing the powder adding operation, the user needs to remove the sleeve before performing the powder adding operation. For users who use this structure of the powder adding box for the first time, they often forget to remove the sleeve, and forcefully press the piston rod when adding powder, thereby causing damage to the powder adding box or parts on the equipment. At the same time, the powder adding box of this structure needs to remove the sleeve when using it, which brings inconvenience to the user. In order to solve these problems, this embodiment provides a powder adding box.

[0305] like Figures 28 to 34 As shown, the powder adding box 100 of this embodiment includes a main body 1, a pushing member 2 and a limiting device 101. The main body 1 in this embodiment is similar in structure to that in the sixth embodiment and will not be described in detail here.

[0306] like Fig.29 and Fig.31 As shown, the outer surface of the first rod portion 21 of the pushing member 2 also includes a symmetrically arranged receiving groove 211, which can be used to accommodate the limiting device 101. The bottom surface of the receiving groove 211 is provided with a first mounting protrusion 2111, and the side walls on both sides of the bottom surface are respectively provided with shaft holes 2112.

[0307] Fig.29The figure shows the matching relationship between the limiting device 101, the pushing member 2 and the main body 1 when the pushing member 2 is in the initial position. In this embodiment, the limiting device 101 includes a third elastic member 1011 and a second arm 1012 that can rotate relative to the pushing member 2. The second arm 1012 is plate-shaped and has a first side surface 10121 facing the pushing member 2 and a second side surface located on the other side. The first side surface 10121 is provided with a second mounting protrusion 10122. Fig.31 and Fig.32 The lower end of the second arm 1012 is provided with a rotating shaft 10123, which is perpendicular to the longitudinal direction Z of the main body 1, and its two ends are respectively inserted into the shaft hole 2112 located in the receiving groove 211, so that the second arm 1012 can rotate around the rotating shaft 10123. The third elastic member 1011 is a compression spring 1011 and has a strong elastic force. One end of the compression spring 1011 is installed on the first mounting protrusion 2111, and the other end is installed on the second mounting protrusion 10122. The compression spring 1011 has an elastic thrust on the second arm 1012. Under the action of the elastic force, the second arm 1012 extends in a direction away from the receiving groove 211 and forms an angle with the longitudinal direction Z of the main body, that is, the second arm 1012 is in an inclined upward state. The second arm 1012 presses on the notch portion 132 located at the end of the upper end cover 13, forming a certain resistance to the pushing member 2 to limit the pushing member 2 from moving along the longitudinal direction of the main body 1.

[0308] like Fig.33 As shown, a new powder adding box 100 has an inner cylinder 11 filled with carbon powder, and the piston portion 23 of the pushing member 2 is at the upper end of the inner cylinder 11. At this time, the pushing member 2 is in the initial position. When the pushing member 2 is not affected by external force, the second arm portion 1012 of the limiting device 101 presses against the upper end cover 13 to form resistance to the pushing member 2, so that the pushing member 2 remains in the initial position. Under the action of the limiting devices 101 located on both sides of the first rod portion 21, the pushing member 2 can remain in the initial position or automatically return to the initial position when the pushing member 2 is subjected to external collision. When performing the powder adding operation, the user can directly push the pressing portion 22 of the pushing member 2 to generate a pushing force acting on the pushing member 2 along the pushing direction P of the pushing member 2. Under the action of the pushing force, the pushing member 2 overcomes the resistance of the limiting device 101 and moves along the pushing direction P. At the same time, combined with Fig.34, the second arm 1012 follows the pushing member 2 to move along the advancing direction P, and under the interference of the inner cylinder 11, overcomes the elastic force of the compression spring 1011 and rotates around the rotation axis 10123 toward the receiving groove 211. Since the receiving groove 211 is large enough to accommodate the second arm 1012, when the force acting on the pushing member 2 along its advancing direction P reaches a preset threshold (i.e., when a certain force is reached), the second arm 1012 can eventually enter the receiving groove 211 as the pushing member 2 moves longitudinally under the interference of the inner cylinder 11. At this time, the limiting device 101 releases the restriction on the pushing member 2, i.e., the limiting device 101 has little or no resistance to the pushing member 2. As the pushing member 2 moves, the carbon powder in the inner cylinder 11 is gradually discharged from the powder outlet.

[0309] A new powder adding box 100, when the pushing member 2 is not affected by external force, under the restriction of the limiting device, the pushing member 2 is maintained at the upper end of the main body relative to the main body. When adding powder, it is only necessary to push the pushing member 2 hard to add powder, and there is no need to disassemble the limiting device 101. The powder adding operation is simple, convenient and fast.

[0310] The second arm 1012 of this embodiment is configured as a plate-like structure, which is only a preferred solution. The second arm 1012 can also be a rod-shaped structure, etc. In addition, the limiting device 101 can also be an elastic arm fixedly connected to the pushing member 2, the elastic arm extends in a direction away from the pushing member 2 and abuts against the end surface of the upper end cover 13. When the pushing member 2 reaches a certain pressure, the pushing member 2 overcomes the force of the elastic arm and moves in the longitudinal direction Z of the main body 1 toward the powder outlet. The elastic arm bends and deforms with the movement of the pushing member 2 and is finally accommodated in the accommodating groove 211. Of course, the accommodating groove can also be eliminated, as long as the space between the pushing member and the main body is sufficient for the second arm to avoid.

[0311] like Figures 35 to 38As shown in the figure, as a variation of the eighth embodiment, the limiting device 101 of this embodiment includes an elastic arm 1013 and a limiting portion 1014. The inner wall of the upper end of the main body 1 of the powder adding box 100 is provided with a mounting groove 110 for mounting the elastic arm 1013. The mounting groove 110 can be a circular groove. The elastic arm 1013 is cylindrical. The outer diameter of the elastic arm 1013 is the same as or slightly smaller than the inner diameter of the mounting groove 110. The elastic arm 1013 itself is elastic and can be deformed when subjected to external force. One end of the elastic arm 1013 protruding from the inner wall of the main body 1 abuts against the limiting portion 1014. Specifically, one end of the elastic arm 1013 protruding from the inner wall of the main body 1 is located below the limiting portion 1014 and abuts against the limiting portion 1014, thereby forming a resistance to the pushing member 2 to limit the longitudinal movement of the pushing member 2 along the main body 1.

[0312] like Fig.36 As shown, a new powder adding box 100, the main body 1 is filled with carbon powder, the piston part 23 of the pushing member 2 is at the upper end of the main body 1, and the pushing member 2 is at the initial position at this time. When the pushing member 2 is not subjected to external force, the elastic arm 1013 of the limiting device 101 abuts against the lower limit part 1014 of the first rod 2, forming resistance to the pushing member 2, so that the pushing member 2 remains in the initial position. Under the action of the limiting devices 101 located on both sides of the first rod 21, the pushing member 2 can remain in the initial position or automatically return to the initial position when the pushing member 2 is subjected to external collision.

[0313] like Fig.37 As shown, when performing the powder adding operation, the user can directly push the pressing portion 22 of the pushing member 2 to generate a pushing force acting on the pushing member 2 along the pushing direction P of the pushing member 2. Under the action of the pushing force, the pushing member 2 overcomes the resistance between the elastic arm 1013 and the limiting portion 1014 and moves along the pushing direction P. At this time, the elastic arm 1013 begins to deform. As the pushing force further increases, the pushing member 2 continues to move, and the deformation degree of the elastic arm 1013 increases. When the force along the pushing direction P of the pushing member 2 reaches a preset threshold (that is, when a certain force is reached), the elastic arm 1013 is deformed to completely cross the limiting portion 1014. At this time, the limiting device 101 releases the restriction on the pushing member 2, and the pushing member 2 moves along the pushing direction P, and the carbon powder in the main body 1 is gradually discharged from the powder outlet. Fig.38As shown, after the limiting device 101 releases the restriction on the pushing member 2, that is, after the limiting portion 1014 passes over the elastic arm 1013, the resistance of the elastic arm 1013 to the limiting portion 1014 disappears, the movement of the pushing member 2 becomes relatively easy, and the elastic arm 1013 recovers its deformation after passing over the limiting portion 1014.

[0314] Optionally, the elastic arm 1013 can also be other shaped structures, such as flat, prismatic, etc. There is no strict restriction on its shape, as long as it can play the function of limiting the position of the pushing member 2. The shape of the corresponding mounting groove 110 can also correspond to the shape of the elastic arm 1013.

[0315] Optionally, the elastic arm can also be arranged on the first rod portion, and the limiting portion is arranged on the inner wall of the main body. Specifically, a mounting groove is provided on the outer surface of the first rod portion, one end of the elastic arm is installed in the mounting groove, and the other end protrudes from the outer surface of the first rod portion. The limiting portion is a flange formed on the inner wall of the main body. In the initial position, one end of the elastic arm protruding from the outer surface of the first rod portion abuts against the limiting portion, and the limiting portion forms a resistance to the elastic arm, thereby limiting the longitudinal movement of the pushing member along the main body. During the powder adding operation, the pushing member overcomes the force of the elastic arm and moves in the longitudinal Z direction of the main body close to the powder outlet. The elastic arm bends and deforms as the pushing member moves, and finally deforms to be able to cross the limiting portion.

[0316] Embodiment 9

[0317] In the existing powder adding box, the pushing member for pushing powder includes a rod part and a piston part, and the rod part is roughly the same length as the main body of the powder adding box containing the developer, and occupies a relatively large volume of the powder adding box, while the main body actually contains the developer, resulting in low utilization of the powder adding box; and the large space occupied increases the packaging cost and transportation cost, etc. In order to solve these problems, this embodiment provides a powder adding box.

[0318] like Figure 39 to Figure 42As shown, the powder adding box of this embodiment includes a main body B1, a pushing member B2 and a force applying member B22. In this embodiment, the main body B1 includes an inner cylinder B11 and an outer cylinder B12, a developer discharge portion B14 and a developer chamber B111. Specifically, the inner cylinder B11 is a cylindrical hollow cylinder, and the outer cylinder B12 can be a cylindrical hollow cylinder. The outer cylinder B12 can also be other shapes, such as a rectangular parallelepiped or prismatic hollow cylinder. The outer cylinder B12 is sleeved on the outside of the inner cylinder B11, and the hollow part of the inner cylinder B11 constitutes a developer chamber B111 for accommodating a developer (such as toner). A second through groove B121 is arranged on the side wall of the outer cylinder B12 along the longitudinal Z direction of the main body B1. There are two second through grooves B121, which are arranged opposite to each other. A third through groove B112 is arranged on the side wall of the inner cylinder B11 along the longitudinal Z direction of the main body B1. There are two third through grooves B112, which are arranged opposite to each other. The positions of the two second through grooves B121 and the third through grooves B112 correspond to each other. The upper ends of the inner cylinder B11 and the outer cylinder B12 are open, and the upper end of the outer cylinder B12 is provided with a top cover 122 adapted to the outer cylinder B12. The developer discharge portion B14 of the powder box is located at the lower end of the main body B1, which may be the lower end of the outer tube B12. The developer outlet B113 is arranged at the lower end of the inner tube B11, and the carbon powder is discharged from the outside of the main body B1 through the developer outlet B113.

[0319] Optionally, the main body B1 may also be provided with only one cylinder, that is, only the outer cylinder B12 or the inner cylinder B11.

[0320] The pushing member B2 is used to push the carbon powder. Before the powder adding operation, the pushing member B2 is in the first position. After the powder adding operation is completed, the pushing member B2 is in the second position. Preferably, the position of the pushing member B2 at the upper end of the main body B1 is the first position. At this time, the carbon powder in the main body B1 has not been pushed out of the main body B1, that is, the pushing member B2 is in the initial position. The pushing member B2 can move along the longitudinal Z direction of the main body B1 in the direction close to the developer outlet B113 (i.e., move downward), so that the carbon powder contained in the main body B1 is discharged from the developer outlet B113 of the developer discharge part B14. The pushing member B2 moves to the position where its lower end contacts the bottom of the inner wall of the main body B1 as the second position (the pushing member B2 cannot move downward any further). In this embodiment, the pushing member B2 is inserted into the main body B1 from the upper end of the main body B1. Specifically, the pushing member B2 is inserted into the inner cylinder B11 and can move relative to the main body B1. The pushing member B2 includes a piston portion B21, which is sealed and connected to the main body B1 and can slide along the inner wall of the main body B1.

[0321] The force member B22 is used to drive the pushing member B2 to move in the direction close to the developer outlet B113. The force member B22 can be provided with two, which are respectively provided on the two side walls of the piston portion B21. Specifically, the force member B22 can be a cylindrical component, the first end of which is connected to the piston portion B21, and the second end of which extends out of the outer wall of the main body B1 from the third through groove B112 and the second through groove B121. The force member B22 can move up and down along the second through groove B121 and the third through groove B112 under the action of external force. The second end of the force member B22 is provided with a third through groove B121. Two combining parts B221, the second combining part B221 is used to install the first pulling member B23, specifically, the second combining part B221 is a groove set at the second end of the force-applying member B22, the first pulling member B23 can be a pull ring, the pull ring is fixed in the groove and thus fixed on the force-applying member B22, and a downward force is applied to the pull ring, driving the piston part B21 to move along the longitudinal Z direction of the main body B1 in the direction close to the developer outlet B113 (i.e., downward), so that the carbon powder contained in the inner cylinder B11 is discharged from the developer outlet B113 of the developer discharge part.

[0322] Optionally, the force-applying member B22 and the piston portion B21 are an integrally formed structure.

[0323] Optionally, the force member B22 and the piston part B21 are separate structures, a through hole is opened on the side wall of the piston part B21, and the first end of the force member B22 is inserted into the through hole to be fixed on the piston part B21; alternatively, the force member B22 is directly adhered and fixed to the side wall of the piston part B21.

[0324] Optionally, the force-applying member B22 may also be other shaped structures, such as a rectangular parallelepiped, a prism, a strip, etc. There is no strict limitation on its shape, as long as its second end can pass through the second through slot B121 and the third through slot B112 and extend out of the outer wall of the main body B1.

[0325] Optionally, the first pulling member B23 may also be a hook, a pull rope, a pull rod, a tension spring, etc. The second connecting portion B221 may be configured corresponding to the first pulling member B23, and may be a groove, a through hole, a connecting rod, etc.

[0326] Alternatively, the first pulling member B23 and the second coupling portion B221 may be omitted, and a force is directly applied to the force applying member B22 to move the pushing member B2 downward.

[0327] Optionally, the first pulling member B23 is the force-applying member B22. Specifically, the force-applying member B22 may be a tension spring, one end of which is directly connected to the piston portion B21, and the other end of which extends out of the side wall of the main body B1. Applying a downward force to the tension spring can also achieve the goal of moving the piston portion B21 along the longitudinal direction Z of the main body B1 in a direction close to the developer outlet B113 (i.e., moving downward).

[0328] Optionally, the force applying member B22 is provided as one.

[0329] The first sealing member B15 is used for sealing the second through groove B121. The first sealing member B15 includes two first sealing strips B151. The two first sealing strips B151 are arranged side by side in a close relationship in the second through groove B121. The two first sealing strips B151 are in a close relationship with each other when not subjected to external force. When subjected to external force, the two first sealing strips B151 can be compressed, thereby separating the two first sealing strips B151. The non-closed side of the two first sealing strips B151 is fixed to the second through groove B121. The first sealing member B15 may be a sponge, which may be pasted and fixed to the second through groove B121. When the force member B22 moves up and down, the force member B22 may compress the first sealing member B15, so that the side where the two first sealing strips B151 are in contact with each other is separated. The force member B22 moves in the gap between the two first sealing strips B151. The positions where the force member B22 has not moved to on the two first sealing strips B151 will not separate. The positions where the force member B22 has moved to will restore the deformation of the two first sealing strips B151. Optionally, the first sealing member B15 may also be felt or rubber.

[0330] The second sealing member B16 is used for sealing the third through groove B112. The second sealing member B16 includes two second sealing strips B161. The two second sealing strips B161 are arranged side by side in the third through groove B112. The two second sealing strips B161 are in a state of being in contact with each other when not subjected to external force. When subjected to external force, the two second sealing strips B161 can be compressed, thereby separating the two second sealing strips B161. The non-contacting side of the two second sealing strips B161 is fixed to the third through groove B112. Specifically, The second sealing member B16 may be a sponge, which may be pasted and fixed in the third through groove B112. When the force member B22 moves up and down, the force member B22 may compress the second sealing member B16, so that the side where the two second sealing strips B161 are in contact with each other is separated. The force member B22 moves in the gap between the two second sealing strips B161. The positions where the force member B22 has not moved to on the two second sealing strips B161 will not separate. The positions where the force member B22 has moved to will restore the deformation of the two second sealing strips B161. Optionally, the second sealing member B16 may also be felt or rubber.

[0331] When a new powder adding box is added, the user can insert the developer discharge portion B14 of the powder adding box into the connecting port of the imaging device, and rotate the powder adding box so that the developer outlet B113 of the powder adding box is connected to the toner supply inlet of the developing box 200 in the imaging device. Fig.42As shown, a downward force is applied to the force-applying member B22, thereby driving the pushing member B2 to move along the longitudinal Z direction of the main body B1 in the direction close to the developer outlet B113 (i.e., downward), so that the carbon powder contained in the main body B1 is discharged from the developer outlet B113 of the developer discharge portion. At the same time, the force-applying member B22 squeezes the first seal B15 and the second seal B16 and moves downward in the second through groove B121 and the third through groove B112 until the lower end of the pushing member B2 contacts the inner wall of the lower end of the main body B1. Then, the force that causes the pushing member B2 to move downward is stopped, and the powder adding operation is completed.

[0332] In the powder adding box of the above structure, at least a part of the force-applying member B22 is located on the outside of the side wall of the main body B1. The user applies force to the force-applying member to make the pushing member B2 move downward to add powder. Compared with the existing powder adding box, the powder adding box of this structure has a shorter overall length, which is conducive to the miniaturization of the powder adding box and reduces the space occupied, thereby reducing the packaging cost and transportation cost.

[0333] Embodiment 10

[0334] like Figure 43 to Figure 45 As shown, the powder box of this embodiment includes a main body C1 and a pushing member C2. The main body C1 in this embodiment can be in the form of a single cylinder in the first embodiment, or in the form of an inner and outer cylinder in the ninth embodiment. However, compared with the ninth embodiment, the second through groove B121 and the third through groove B112, and the first seal B15 and the second seal B16 are omitted in the main body C1. The other structures of the main body C1 are similar to those of the above-mentioned embodiments and will not be repeated here.

[0335] like Figure 43 to Figure 45As shown, the pushing member C2 of this embodiment is different from the above-mentioned multiple embodiments in that the pushing member C2 of this embodiment is foldable. Specifically, the pushing member C2 includes a piston portion C21, a second pushing portion C22, a pivot portion C23 and a force-bearing portion C24. A third connecting portion C211 is provided on the top of the piston portion C21. The first end of the pivot portion C23 is connected to the third connecting portion C211. Specifically, a third through hole C25 can be provided on the third connecting portion C211, and a fourth through hole C26 can be provided on the pivot portion C23. The first connecting shaft C27 passes through the third through hole C25 on the third connecting portion C211 and the fourth through hole C26 on the pivot portion C23 in sequence, so that the pivot portion C23 is hinged on the third connecting portion C211, thereby making the pivot portion C23 The pivoting portion C23 can rotate around the first connecting axis C27. When the pivoting portion C23 rotates to a position that fits on the top of the piston portion C21 (i.e., the pivoting portion C23 is in a horizontal state), the second end of the pivoting portion C23 protrudes from the side wall of the main body C1, and the second end of the pivoting portion C23 can be provided with a fifth through hole C28. The first end of the second pushing portion C22 is provided with a third connecting axis C29 that matches the fifth through hole C28. The third connecting axis C29 is inserted into the fifth through hole C28 to connect the second pushing portion C22 to the second end of the pivoting portion C23, and the second pushing portion C22 can rotate around the second end of the pivoting portion C23. Optionally, the third connecting axis C29 can be provided at the second end of the pivoting portion C23, and the fifth through hole C28 can be provided at the first end of the second pushing portion C22. The force-bearing portion C24 is arranged at the second end of the second pushing portion C22, and the force-bearing portion C24 rotates with the second pushing portion C22. In this embodiment, the force-bearing portion C24 can be flat, and a notch is arranged on the force-bearing portion C24, and the notch can be matched with the outer wall of the main body C1. When the second pushing portion C22 rotates to fit the outer wall of the main body C1, the notch is stuck on the outer wall of the main body C1. Preferably, the second pushing portion C22, the pivoting portion C23 and the force-bearing portion C24 are arranged in two groups, and the two groups of structures are arranged oppositely.

[0336] like Fig.43 As shown in the figure, a new powder adding box, before the powder adding operation, the pivoting portion C23 can be in a state of being in contact with the top of the piston portion C21, and the second pushing portion C22 is in a state of being in contact with the outer wall of the main body C1. When the powder adding operation is performed, the user can insert the developer discharge portion C14 of the powder adding box into the connecting port of the imaging device, and rotate the powder adding box so that the developer outlet C113 of the powder adding box is connected to the toner replenishing inlet of the developer box in the imaging device, as shown in FIG. Fig.45As shown, a force is applied to the pivoting part C23 to make it rotate, so that the pivoting part C23 rotates to a state perpendicular to the piston part C21 (i.e., along the Z direction), and a force is applied to the second pushing part C22 to make it rotate, so that the second pushing part C22 rotates to a state in the same straight line with the pivoting part C23 (i.e., along the Z direction). At this time, the force-bearing part C24 is at the uppermost end, and the force-bearing part C24 is pressed to apply a downward force, thereby driving the entire pushing member C2 to move along the longitudinal Z direction of the main body C1 in the direction close to the developer outlet C113 (i.e., moving downward), so that the carbon powder contained in the main body C1 is discharged from the developer outlet C113 of the developer discharge part until the lower end of the pushing member C2 contacts the inner wall of the lower end of the main body C1, and then the force to move the pushing member C2 downward is stopped, and the powder adding operation is completed.

[0337] The powder adding box of the above structure, the rotatable structure of the second pushing part C22 and the pivot part C23 allows the pushing member C2 to be folded, so that the length of the pushing member C2 is reduced, and the overall length of the powder adding box is reduced, which is conducive to the miniaturization of the powder adding box and reduces the occupied space, thereby reducing the packaging cost and transportation cost; it can well solve the problems of the existing powder adding box occupying a large space, high packaging cost and transportation cost.

[0338] Embodiment 11

[0339] The existing powder adding box transmits electrical signals to the imaging device by changing the conductive steel sheets of the two connecting chips from the contact state to the separation state to transmit the powder adding information; when the contact state changes to the disconnected state, the voltage will change, and the imaging device will recognize the voltage change to determine whether the powder adding operation is completed.

[0340] Specifically, an insertion strip is provided. When the powder adding operation is completed by pressing the piston rod of the powder adding box, the insertion strip is inserted into the connection between the two conductive steel sheets, so that the two conductive steel sheets in contact are separated from each other, that is, the circuit is disconnected. At this time, an electrical signal is transmitted to the imaging device to identify that the powder adding operation is completed.

[0341] In the powder adding box of the above structure, since the surface of the conductive steel sheet is smooth, the inserting strip is easily separated from the conductive steel sheet during the process of inserting the inserting strip into the connecting part of the conductive steel sheet, resulting in the inability to separate the two conductive steel sheets in contact, and the voltage cannot be changed, so the imaging device cannot determine whether the powder adding operation is completed. In order to solve these problems, the present embodiment provides a powder adding box.

[0342] like Figures 46 to 52As shown, the powder box 100 of this embodiment includes a main body 1, a pushing member 2, an electrical interface 3 and a switch device 107. The structure of the main body 1 is similar to that of the first embodiment and will not be repeated here. The structure of the pushing member 2 is different from that of the first embodiment in that the first rod portion 21 includes a fourth through groove 214 arranged on its circumferential side wall and extending along the longitudinal direction Z of the main body. The length of the fourth through groove 214 is greater than the distance from the lower end of the pushing member 2 to the developer outlet 113, and a second protrusion 215 is provided at the upper end of the fourth through groove 214.

[0343] like Fig.47 As shown, the electrical interface 3 is used for communication between the powder box 100 and the imaging device. The electrical interface 3 is arranged at the side surface of the main body. In response to the push member 2 moving from the first position (the initial position before adding powder) to the second position (the position after adding powder), the signal can be transmitted to the imaging device through the electrical interface 3. The electrical interface 3 can be a chip (memory), a wireless transmitter, and other types of electrical interfaces 3. The electrical interface 3 can send a signal to the imaging device in response to the circuit being turned on in response to the closure of the switch device 107. The electrical interface 3 can be connected to an external electrical interface 3, such as an electrical interface of an imaging device. The electrical interface 3 can be a wireless transmitter, such as a Bluetooth, Bluetooth low energy and / or radio frequency identification (RFID) transmitter, and other types of wireless transmitters.

[0344] like Fig.47 and Fig.48As shown, the powder box 100 also includes a switch device 107, which includes a first magnet 1071, a second magnet 1072, a movable part 1073, a first conductive connecting part 61 and a second conductive connecting part 62. The movable part 1073 is roughly in the shape of a long flat strip and is longitudinally arranged on the side surface of the main body. A first protrusion 10731 is provided on the top of the movable part 1073, and the first protrusion 10731 is embedded in the fourth through groove 214. The pushing member 2 is provided with a second protrusion 215 that cooperates with the first protrusion 10731, and the second protrusion 215 is arranged at the upper end of the fourth through groove 214. In the process of moving the pushing member 2 from the first position to the second position, the second protrusion 215 abuts against the first protrusion 10731, thereby driving the movable part 1073 to move in the direction close to the developer outlet (moving downward). The upper end of the movable member 1073 is provided with a fastening portion 10732, and the side surface of the main body is provided with a positioning portion 17 that cooperates with the fastening portion 10732. Specifically, the fastening portion 10732 is an elastic buckle 10732 that can generate deformation, and the positioning portion 17 is a third protrusion 17. When the pushing member 2 is in the first position, the fastening portion 10732 is located on the upper side of the positioning portion 17. The lower end of the movable member 1073 is provided with a mounting frame 10733, and the mounting frame 10733 is used to mount the first magnet 1071. The mounting frame 10733 may not be provided, and the first magnet 1071 is glued and fixed to the lower end of the movable member 1073. The second magnet 1072 is fixedly connected to the first conductive connecting member 61 near its second end. The second magnet 1072 can be glued and fixed to the first conductive member. When the pushing member 2 is in the first position, the first magnet 1071 is located on the upper side of the second magnet 1072.

[0345] like Fig.47 and Fig.48 As shown, the first conductive connector 61 and the second conductive connector 62 can be metal sheets, such as steel sheets, copper sheets, aluminum alloy sheets, etc., or other non-metallic materials, such as conductive plastic sheets, conductive rubber sheets, etc. The second conductive connector 62 is fixed on the outer surface of the main body and one end of it is connected to the electrical interface 3. The first conductive connector 61 is fixed on the outer surface of the main body and the first end of it is connected to the electrical interface 3. The second end of the first conductive connector 61 presses on the surface of the second conductive connector 62 to form an electrical connection, that is, the circuit is in a closed state, and current can flow between the electrical interface 3 and the first conductive connector 61 and the second conductive connector 62. The first conductive connector 61 presses on the surface of the second conductive connector 62 to form an elastic contact.

[0346] The powder adding box 100 also includes a protective cover 5, which is roughly in the shape of a strip and is longitudinally arranged on the side surface of the main body 1. The protective cover 5 is used to cover the first conductive connecting member 61, the second conductive connecting member 62, the switch device 107 and other components arranged on the outer wall of the main body 1 to play a protective role.

[0347] like Figures 49 to 52 As shown, a new powder adding box, when performing a powder adding operation, the user can insert the developer discharge portion 14 of the powder adding box 100 into the connecting port of the imaging device, rotate the powder adding box 100 so that the developer outlet 113 of the powder adding box 100 is connected with the toner replenishing inlet 201 of the developer box 200 in the imaging device, press the pushing member 2 to move along the longitudinal direction of the main body (along the Z direction), and the toner is discharged from the developer outlet 113 of the developer discharge portion 14. When pressed to near the bottom (i.e., the second position), the second protrusion 215 on the side wall of the pushing member 2 presses against the first protrusion 10731 on the top of the movable member 1073, and the movable member 1073 moves downward with the pushing member 2, and the lower end of the buckle 10732 of the movable member 1073 begins to contact the third protrusion 17 on the side wall of the main body. The movable part 1073 continues to move downward until the lower end of the buckle 10732 is separated from the upper end of the third protrusion 17, and the deformation is restored. The upper end of the buckle 10732 is engaged with the lower end of the third protrusion 17, and the movable part 1073 moves downward to drive the first magnet 1071 to move downward synchronously. The first magnet 1071 and the second magnet 1072 attract each other, which can cause the second end of the first conductive connecting part 61 to be deformed, so that the second end of the first conductive connecting part 61 is separated from the surface of the second conductive connecting part 62, and the current cannot pass between the first conductive connecting part 61 and the second conductive connecting part 62, that is, the circuit is disconnected, the voltage changes, and the signal is transmitted from the electrical interface 3 to the imaging device. The imaging device receives the voltage change signal and recognizes that the powder adding is completed. The voltage change signal also has another function. When the imaging device receives the voltage change signal, it controls the unlocking of the toner box, and the toner box can be rotated and taken out. If the toner box is locked by the imaging device during the toner adding process, the box cannot be rotated and pulled out. After the toner adding is completed, the imaging device receives the electrical signal and unlocks it, and the toner box can be rotated 180 degrees and taken out.

[0348] Optionally, when the first conductive connector 61 and the second conductive connector 62 are in the initial state (i.e., when the pushing member 2 is in the first position), the second end of the first conductive connector 61 does not contact the surface of the second conductive connector 62, i.e., the circuit is in an open state, and the first magnet 1071 and the second magnet 1072 are set to repel each other. When the pushing member 2 moves from the first position to the second position, the first magnet 1071 and the second magnet 1072 repel each other, which can cause the second end of the first conductive connector 61 to deform, and the repulsive force pushes the second end of the first conductive connector 61 to move toward the second conductive connector 62 and finally presses against the surface of the second conductive connector 62 to form an electrical connection, i.e., the circuit changes from an open state to a closed state, the voltage changes, and the signal is transmitted from the electrical interface 3 to the imaging device. The imaging device receives the voltage change signal and recognizes that the powder adding is completed.

[0349] The toner box of the above structure disconnects the circuit by the attraction of the first magnet 1071 and the second magnet 1072 that attract each other after the switch device 107 approaches, and the signal of the voltage change is accurately transmitted to the imaging device, so that the imaging device can accurately recognize that the toner adding operation is completed.

[0350] Embodiment 12

[0351] like Figure 53 to Figure 57 As shown, the powder adding box 100 of this embodiment includes a main body 1, a pushing member 2, an electrical interface 3, a locking device 103, a force applying component 106 and a switch device 107. The structure of the pushing member 2 in this embodiment is similar to that of the fourth embodiment, the locking device 103 is similar to that of the second embodiment, and the force applying component 106 is similar to that of the fourth embodiment, which will not be described in detail here, and only the differences will be described.

[0352] like Figure 54 to Figure 57 As shown, the switch device 107 includes a first magnet 1071, a second magnet 1072, a lever member 1074, a first conductive connecting member 61 and a second conductive connecting member 62. The lever member 1074 has a first arm 10741 and a second arm 10742. A lever fulcrum 18 is provided on the outer wall of the main body 1. The first arm 10741 and the second arm 10742 can rotate around the lever fulcrum 18. The first magnet 1071 is connected to the first arm 10741, and the second arm 10742 is inserted into the connection between the first conductive connecting member 61 and the second conductive connecting member 62. At least a portion of the first conductive connecting member 61 is pressed against the surface of the second conductive connecting member 62 to form an electrical connection, that is, the circuit is in a closed state. The second magnet 1072 is fixedly connected to the pushing member 2. Specifically, the second magnet 1072 is fixed to the top of the piston portion 23. When the pushing member 2 moves from the first position to the second position, the first magnet 1071 and the second magnet 1072 attract each other. A fourth elastic member 1075 is provided on the side wall of the main body 1, and the fourth elastic member 1075 is connected to the first magnet 1071. When the first magnet 1071 and the second magnet 1072 attract each other, the fourth elastic member 1075 is compressed. Specifically, the fourth elastic member 1075 can be a compression spring, or a spring sheet, a tension spring, an elastic sponge, etc. The fourth elastic member 1075 is provided to enable the first magnet 1071 to remain stable when not subjected to the force of the second magnet 1072, thereby preventing the fourth elastic member 1075 and the first arm 10741 connected to the fourth elastic member 1075 from shaking / rotating at will, thereby causing the second arm 10742 of the lever member 1074 to pry the first conductive connector 61 to disconnect from the second conductive connector 62, thereby generating an erroneous voltage change signal.

[0353] During the powder adding operation, after the locking device 103 is unlocked, the force-applying component 106 is compressed and begins to recover, pushing the pushing member 2 to move downward. When the pushing member 2 moves from the first position to the second position, the first magnet 1071 and the second magnet 1072 attract each other, the first magnet 1071 compresses the fourth elastic member 1075, and the first arm 10741 and the second arm 10742 of the lever member 1074 rotate around the lever fulcrum 18 (the first arm 10741 rotates toward the direction of approaching the main body 1, and the second arm 10742 rotates away from the main body 1). The second arm 10742 pries the first conductive connecting member 61 away from the surface of the second conductive connecting member 62, and the first conductive connecting member 61 is disconnected from the second conductive connecting member 62, that is, the circuit is disconnected, the voltage changes, and the signal is transmitted from the electrical interface 3 to the imaging device. The imaging device receives the voltage change signal and recognizes that the powder adding is completed.

[0354] Optionally, when the first conductive connector 61 and the second conductive connector 62 are in the initial state (i.e., when the pushing member 2 is in the first position), the second arm 10742 of the lever member 1074 is in the state of prying up the first conductive connector 61, and the first conductive connector 61 does not contact the surface of the second conductive connector 62, i.e., the circuit is disconnected, the first magnet 1071 and the second magnet 1072 are configured to repel each other, and the fourth elastic member 1075 is configured to be a tension spring. When the pushing member 2 moves from the first position to the second position, the first magnet 1071 and the second magnet 1072 repel each other, and the repulsive force is greater than the tension spring. Due to the tension of the extension spring, the first arm 10741 and the second arm 10742 of the lever member 1074 rotate around the lever fulcrum 18, and the second arm 10742 rotates toward the second conductive connecting member 62, and no longer pries up the first conductive connecting member 61. The first conductive connecting member 61 elastically recovers its deformation toward the second conductive connecting member 62, and finally at least a portion of the first conductive member presses on the surface of the second conductive connecting member 62 to form an electrical connection, that is, the circuit changes from an open state to a closed state, the voltage changes, and the signal is transmitted from the electrical interface 3 to the imaging device. The imaging device receives the voltage change signal and recognizes that the powder adding is completed.

[0355] Embodiment 13

[0356] like Figure 58 to Figure 61As shown, the powder box of this embodiment is different from that of the twelfth embodiment in that the switch device 107 includes a second pulling member 1076, a rotating member 1077, a first conductive connecting member 61 and a second conductive connecting member 62, and the rotating member 1077 includes a third arm 10771 and a fourth arm 10772 connected to each other, and the third arm 10771 and the fourth arm 10772 are arranged at a certain angle. In this embodiment, the angle between the third arm 10771 and the fourth arm 10772 is an obtuse angle, and can also be an acute angle or a right angle. A through hole is set at the intersection of the support arms 10772, and a support shaft 19 matching the through hole is set on the outer wall of the main body 1. The third support arm 10771 and the fourth support arm 10772 can rotate around the support shaft 19. The free end of the third support arm 10771 is connected to one end of the second pulling member 1076. Under the action of the second pulling member 1076, the free end of the fourth support arm 10772 is inserted into or detached from the connection between the first conductive connecting member 61 and the second conductive connecting member 62. The fourth support arm 10772 is set as an insulating member, or the entire rotating member 1077 can be set on the insulating member. One end of the second pulling member 1076 is connected to the rotating member 1077, and the other end is connected to the pushing member 2. Specifically, the other end of the second pulling member 1076 is connected to the top of the piston part 23. The other end of the second pulling member 1076 enters the main body 1 from the upper end of the main body 1 and is connected to the piston part 23. In this embodiment, the second pulling member 1076 can be a rope. Optionally, the second pulling member 1076 can also be a line, a steel wire, etc. When the pushing member 2 is in the first position, the second pulling member 1076 is in a relaxed state and is not straightened. At this time, the free end of the fourth arm 10772 of the rotating member 1077 is not inserted into the connection between the first conductive connector 61 and the second conductive connector 62 or is partially inserted into the connection between the first conductive connector 61 and the second conductive connector 62. At this time, at least a part of the first conductive connector 61 and the second conductive connector 62 presses against the surface of the second conductive connector 62 to form an electrical connection, that is, the circuit is in a closed state. The force-applying component 106 in this embodiment is a tension spring, which is located between the piston portion 23 and the bottom of the main body 1. One end of the tension spring 106 is connected to the fifth hook 114 located at the lower end of the main body 1, and the other end is connected to the sixth hook 231 located at the bottom of the piston portion 23, so that the tension spring 106 is in a stretched state and has an elastic pulling force on the pushing member 2.

[0357] like Figure 58 to Figure 61As shown, during the powder adding operation, after the locking device 103 is unlocked, the tension spring 106 begins to contract, pulling the pushing member 2 downward, and when the pushing member 2 moves from the first position to the second position, the second pulling member 1076 is straightened, and the second pulling member 1076 pulls the rotating member 1077 to rotate around the support shaft 19, and the free end of the fourth arm 10772 of the second pulling member 1076 is completely inserted into the connection between the first conductive connector 61 and the second conductive connector 62, so that the first conductive connector 61 and the second conductive connector 62 are completely separated, the circuit is disconnected, the voltage changes, and the signal is transmitted from the electrical interface 3 to the imaging device. The imaging device receives the voltage change signal and recognizes that the powder adding is completed.

[0358] Optionally, in the initial state (i.e., the pushing member 2 is in the first position), the free end of the fourth arm 10772 of the rotating member 1077 is completely inserted into the connection between the first conductive connector 61 and the second conductive connector 62, and the first conductive connector 61 and the second conductive connector 62 are in a separated state, that is, the circuit is in a disconnected state. When the pushing member 2 moves from the first position to the second position, the second pulling member 1076 is straightened, pulling the free end of the fourth arm 10772 of the rotating member 1077 to disengage from the connection between the first conductive connector 61 and the second conductive connector 62, and at least a portion of the first conductive connector 61 contacts the second conductive connector 62 to form an electrical connection. The circuit changes from an open state to a closed state, the voltage changes, and the signal is transmitted from the electrical interface 3 to the imaging device. The imaging device receives the voltage change signal and recognizes that the powder adding is completed.

[0359] Optionally, a tilting portion may be provided on the first conductive connecting member 61 to facilitate the free end of the fourth arm 10772 of the rotating member 1077 to be inserted into the connection between the first conductive connecting member 61 and the second conductive connecting member 62 when rotating.

[0360] Embodiment 14

[0361] The capacity of the existing toner cartridge needs to match the capacity of the internal chamber of the developer cartridge. For example, when the imaging device shows that the developer cartridge is short of toner, it is necessary to add one or more toner cartridges of toner capacity to the developer cartridge at one time. Adding too much or too little toner will have an adverse effect on the printing of the device. In view of this, for different types of developer cartridges, manufacturers need to produce toner cartridges of different capacities to match them. It can be seen that the existing toner cartridges are not universal, which increases the manufacturing cost and causes waste of resources. To solve these problems, a toner cartridge is provided.

[0362] like Figure 62 to Figure 67As shown, the powder box 100 of the present embodiment includes a main body D1 and a quantitative filling mechanism; specifically, the powder box 100 of the present embodiment also includes a second developer accommodating chamber D2, a movable part D3, a first one-way valve component D4 and a second one-way valve component D5, wherein the main body D1 includes a first developer accommodating chamber D11 and a developer discharge portion D12. In this embodiment, the first developer holding chamber D11, the second developer holding chamber D2, the movable component D3, the first one-way valve component D4 and the second one-way valve component D5 constitute a quantitative filling mechanism; specifically, the main body D1 is a cylindrical hollow cylinder, the hollow part constitutes the first developer holding chamber D11 for holding the developer (such as toner), the upper end of the first developer holding chamber D11 is open, the developer discharge portion D12 of the powder box 100 is located at the lower end of the main body D1, including a developer outlet D121, and a second channel D7 is provided between the first developer holding chamber D11 and the developer outlet D121, the first developer holding chamber D11 is connected to the developer outlet D121 through the second channel D7, and the toner in the first developer holding chamber D11 is discharged to the outside of the main body D1 through the developer outlet D121. Alternatively, the main body D1 may also be a structure including two sleeved inner and outer cylinders (both inner and outer cylinders are hollow cylinders), and the first developer receiving chamber D11 is the hollow portion of the inner cylinder. Alternatively, the main body D1 may also be other geometric shapes, such as a rectangular parallelepiped or prism-shaped hollow cylinder. The inner wall of the first developer holding chamber D11 is provided with a first limiting position D111 and a second limiting position D112 for limiting the moving range of the movable part. The first limiting position D111 is farther from the developer outlet D121 than the second limiting position D112. Preferably, the first limiting position D111 is provided at the upper end of the first developer holding chamber D11, and the second limiting position D112 is located at the lower side of the first limiting position D111. When the movable part D3 is limited by the first limiting position D111, the movable part D3 is in the first position. When the movable part D3 is limited by the second limiting position D112, the movable part D3 is in the second position. The first limiting position D111 and the second limiting position D112 can be a circle of flanges extending toward the center of the first developer holding chamber D11, or can be a plurality of protrusions distributed on the inner wall of the first developer holding chamber D11 and extending toward the center of the first developer holding chamber D11.

[0363] The movable component D3 is used to extract and push the toner. The movable component D3 can move back and forth between the first position and the second position. Preferably, when the movable component D3 is in the first position at the upper end of the first developer holding chamber D11, the toner in the first developer holding chamber D11 has not been pushed out of the main body D1. The movable component D3 can move in the longitudinal direction Z of the first developer holding chamber D11 in the direction close to the developer outlet D121 (i.e., move downward), so that the toner in the first developer holding chamber D11 is discharged from the developer outlet D121 of the developer discharge portion D12. In this embodiment, the movable component D3 is inserted into the first developer holding chamber D11 from the upper end of the first developer holding chamber D11 and can move relative to the first developer holding chamber D11. The movable component D3 includes a first rod portion D31, a pressing portion D32 located at the upper end of the first rod portion D31, and a piston portion D33 located at the lower end of the first rod portion D31. The movable component D3 in this embodiment is equivalent to the pushing component in the first embodiment, and the structures of the two are roughly the same. The pushing component in the first embodiment can be referred to and will not be described again. The inner diameter of the first rod portion D31 can be matched with the inner diameter of the first limiting position D111, so that when the movable component D3 moves in the longitudinal direction Z of the first developer holding chamber D11 away from the developer outlet D121 (i.e., in the process of moving from the second position to the first position), the top of the piston portion D33 can abut against the bottom of the first limiting position D111, thereby limiting the moving range of the movable component D3, so that the movable component D3 cannot be pulled out of the first developer holding chamber D11. When the movable component D3 moves along the longitudinal direction Z of the first developer holding chamber D11 towards the developer outlet D121 (i.e., in the process of moving from the first position to the second position), the toner contained in the first developer holding chamber D11 is discharged from the developer outlet D121 under the pressure of the movable component D3. When the movable component D3 moves to the second position, the bottom of the piston part D33 can abut against the top of the second limiting position D112, thereby limiting the moving range of the movable component D3, and the movable component D3 can no longer move downward.

[0364] The second developer storage chamber D2 is arranged outside the main body D1. The second developer storage chamber D2 is a roughly rectangular box-shaped structure. A first channel D6 is arranged between the second developer storage chamber D2 and the first developer storage chamber D11. The second developer storage chamber D2 and the first developer storage chamber D11 are connected by the first channel D6. Preferably, the communication port between the second developer storage chamber D2 and the first channel D6 is arranged on the bottom surface D2a of the second developer storage chamber D2, and the communication port between the first developer storage chamber D11 and the first channel D6 is arranged on the side wall of the first developer storage chamber D11. The second developer storage chamber D2 is provided with a powder adding port D21 for adding developer into the second developer storage chamber D2. Preferably, the powder adding port D21 is arranged on the top surface D2b of the second developer storage chamber D2, and a cover D211 for closing the powder adding port D21 is also arranged at the powder adding port D21. The second developer holding chamber D2 is also provided with a vent D22, which is used for ventilation in the second developer holding chamber D2. Preferably, the vent D22 is provided on the top surface D2b of the second developer holding chamber D2, and the vent D22 is covered with a breathable membrane D221, which can also be a breathable net or breathable cloth. The powder adding port D21 and the vent D22 can be through holes of various geometric shapes such as circular, rectangular, square, elliptical, pentagonal, hexagonal, etc. The cover D211 that closes the powder adding port D21 and the breathable membrane D221 that covers the vent D22 are set to shapes corresponding to the powder adding port D21 and the vent D22.

[0365] Optionally, the connecting opening between the second developer holding chamber D2 and the first channel D6 is arranged on the side wall of the second developer holding chamber D2 facing the main body D1; the first channel D6 may also be omitted, and the side wall of the second developer holding chamber D2 may be attached to the side wall of the main body D1, and a channel opening may be arranged at the joint between the two to connect the second developer holding chamber D2 with the first developer holding chamber D11.

[0366] like Fig.66 and Fig.67As shown, the first one-way valve member D4 is arranged in the first channel D6. The first one-way valve member D4 only allows the toner to flow in one direction and is sealed in the other direction. In this embodiment, the first one-way valve member D4 is arranged to only allow the toner to flow from the second developer receiving chamber D2 to the first developer receiving chamber D11. The direction from the first developer receiving chamber D11 to the second developer receiving chamber D2 is sealed, that is, the toner in the first developer receiving chamber D11 cannot flow to the second developer receiving chamber D2. The first one-way valve member D4 is made of a flexible material, preferably an elastic material such as a silicon film. The first one-way valve component D4 is cone-shaped and has a plurality of intersecting slits D41 arranged at equal angles with its center as the intersection point. The end of the cone-shaped first one-way valve component D4 with a smaller diameter faces the first developer holding chamber D11, and the end with a larger diameter faces the second developer holding chamber D2. Under the action of air pressure in one direction (flowing from the second developer holding chamber D2 to the first developer holding chamber D11), the plurality of slits D41 of the first one-way valve component D4 can be opened, while the other direction is closed. The air pressure flowing from the second developer holding chamber D2 to the first developer holding chamber D11 can be generated by the movement of the movable component D3. When the movable component D3 is in the second position, the amount of gas in the first developer holding chamber D11 is small. At this time, in the process of pulling the movable component D3 from the second position to the first position (that is, the movable component D3 moves upward), the volume of the space where the gas in the first developer holding chamber D11 is located becomes larger, and the air pressure in the first developer holding chamber D11 becomes lower. The air pressure in the second developer holding chamber D2 is higher than the air pressure in the first developer holding chamber D11. The gas in the second developer holding chamber D2 flows to the first developer holding chamber D11, pushing the first one-way valve component D4 to open. Due to the air pressure difference between the second developer holding chamber D2 and the first developer holding chamber D11, the developer in the second developer holding chamber D2 will be sucked into the first developer holding chamber D11. The end with a larger diameter of the first one-way valve component D4 is also provided with a mounting portion D42. Specifically, the mounting portion D42 can be a flange extending in a direction away from the center of the first one-way valve component D4. The first one-way valve component D4 is fixed in the first channel D6 by the flange, and can be fixed by welding, gluing, snapping, etc.

[0367] Optionally, the first one-way valve member D4 can also be a truncated cone, hemispherical cone, pyramidal cone or other geometric shape, and there is no strict limitation on its shape, as long as it can achieve the effect of making the developer in the second developer accommodating chamber flow unidirectionally to the first developer accommodating chamber D11.

[0368] Alternatively, the first one-way valve member D4 may be disposed in the second developer accommodating chamber D2 , specifically at the communication port between the second developer accommodating chamber D2 and the first developer accommodating chamber D11 .

[0369] The second one-way valve member D5 is arranged in the second channel D7. The second one-way valve member D5 only allows the toner to flow in one direction and is sealed in the other direction. In this embodiment, the second one-way valve member D5 is arranged to only allow the toner to flow from the first developer storage chamber D11 to the developer outlet D121, and the developer outlet D121 is sealed in the direction of the first developer storage chamber D11. The second one-way valve member D5 is similar to the first one-way valve member D4 in structure and principle. The end of the second one-way valve member D5 with a large diameter faces the first developer storage chamber D11, and the end of the second one-way valve member D5 with a small diameter faces the developer outlet D121. When the movable part D3 moves downward (i.e., in the process of moving from the first position to the second position), the toner contained in the first developer storage chamber D11 pushes open the upper multiple slits of the second one-way valve member D5 under the pressure of the movable part D3, and is discharged from the developer outlet D121.

[0370] Alternatively, the second passage D7 may not be provided, and the second one-way valve member D5 may be directly fixed on the side wall of the first developer accommodating chamber D11.

[0371] The movable component D3 can move between the first position and the second position. When toner needs to be replenished, the movable component D3 is pulled to move from the second position to the first position, the first one-way valve component D4 is opened, and the toner in the second developer receiving chamber D2 enters the first developer receiving chamber D11 through the first one-way valve component D4, and the third sealing member D51 of the second one-way valve component D5 blocks the communication channel. The movable component D3 is pushed to move from the first position to the second position, the first one-way valve component D4 is sealed, the second one-way valve component D5 is opened, and the toner reaches the developer outlet D121 from the first developer receiving chamber D11 and enters the developer cartridge, completing the toner replenishment operation.

[0372] In this embodiment, the volume of the first developer accommodating chamber D11 can be larger than the volume of the second developer accommodating chamber D2, and can also be smaller than the volume of the second developer accommodating chamber D2. The following specifically describes how to achieve quantitative filling of developer in two situations with actual examples.

[0373] Optionally, the first developer holding chamber D11 can be used as the quantitative filling value for each time. For example, if the volume of the first developer holding chamber D11 is set to 100g, and the volume of the second developer holding chamber D2 is 1000g, if the movable component D3 is pulled upward once (from the second position to the first position), 100g of toner can be sucked from the second developer holding chamber D2 into the first developer holding chamber D11. When the movable component D3 is pushed downward (from the first position to the second position), the 100g of toner in the first developer holding chamber D11 can be pushed into the developer box. The pulling and pushing of the movable component D3 constitutes a back and forth action, which can fill 100g of toner into the developer box. When 500g of toner needs to be supplemented, 5 back and forth actions are required. If one back and forth action of the movable component D3 can only suck in 50g of toner, 10 back and forth actions are required, and so on.

[0374] Optionally, the second developer holding chamber D2 can be used as the quantitative filling value for each time. For example, the volume of the second developer holding chamber D2 is set to 100g. A back and forth movement of the movable component D3 can extract all the developer in the second developer holding chamber D2. When 200g of replenishment is needed, toner can be replenished into the second developer holding chamber D2 first, and then powder can be added, and so on.

[0375] Optionally, the toner sucked into the first developer holding chamber D11 can be controlled by the movement of the movable component D3, thereby controlling the amount of toner added to the developer box with each back and forth movement. When the amount added to the developer box reaches a preset amount, the imaging device will send a signal prompt, at which time the toner addition can be stopped.

[0376] The powder adding box 100 of the present invention, by providing a quantitative filling mechanism, can perform one or more quantitative filling according to the developer box of different capacities through the quantitative filling mechanism, thereby being able to solve the technical problems existing in the existing powder adding box 100. With this structure, the amount of carbon powder added can be controlled as needed, and the amount of carbon powder can be added as needed. The applicable range is wide, that is, it can be applicable to a variety of different styles of developer boxes. The powder adding box 100 can be used multiple times, and carbon powder only needs to be added to the second developer holding chamber D2. In addition, the existing powder adding box 100 includes a main body D1 for accommodating the developer and a piston rod. When adding toner to the developing box, the powder adding box 100 is inserted into the connecting port on the printer, and the piston rod is pushed to add all the toner in the powder adding box 100 to the developing box. However, since the toner and gas in the powder adding box 100 are quickly pressed into the developing box at one time during the powder adding operation, a large amount of toner and gas entering the developing box can easily cause a large amount of toner to accumulate at the connecting port of the developing box, causing blockage, which is not conducive to the transportation of toner inside the developing box; at the same time, the air pressure in the developing box will increase rapidly, which will give the air permeable parts (such as the air permeable membrane) of the developing box a large air pressure, thereby causing damage to the air permeable parts (such as the air permeable membrane). The quantitative filling mechanism of the present invention can quantitatively fill the toner in multiple times, which solves the problem of clogging of the developing box and damage to the developing box caused by filling all the toner in the powder adding box 100 at one time in the prior art.

[0377] like Fig.68 and Fig.69As shown, as a variation of the fourteenth embodiment, the difference from the fourteenth embodiment is that the structures of the first one-way valve component D4 and the second one-way valve component D5 are different. In this embodiment, the first one-way valve component D4 and the second one-way valve component D5 include a third sealing component D51 and an elastic return component D52. Taking the second one-way valve component D5 as an example, the third sealing component D51 and the elastic return component D52 are both arranged in the second channel D7 connecting the first developer accommodating chamber D11 and the developer outlet D121. The third sealing component D51 is a roughly cylindrical component with an opening at the lower end and a cavity provided inside. The elastic return component D52 extends into the cavity from the opening of the third sealing component D51 and at least a part of the elastic return component D52 is located in the cavity and is fixed to the third sealing component D51. The part of the elastic return component D52 located outside the third sealing component D51 is aligned with the third sealing component D51. The second channel D7 is fixed, the upper end of the third seal D51 (i.e., the end away from the opening) is toward the first developer holding chamber D11, and the elastic return member D52 is toward the developer outlet D121. In a natural state (i.e., the elastic return member D52 is not subjected to external force), the third seal D51 is in a position lifted up by the elastic return member D52. The third seal D51 can seal the channel opening of the second channel D7 toward the first developer holding chamber D11, and the toner in the first developer holding chamber D11 cannot enter the developer outlet D121. When the movable component D3 moves downward (i.e., in the process of moving from the first position to the second position), the carbon powder contained in the first developer holding chamber D11 pushes the third seal D51 downward under the pushing force of the movable component D32, and compresses the elastic reset component D52 downward, so that the third seal D51 and the elastic reset component D52 move downward, and the third seal D51 is separated from the channel opening of the second channel D7 toward the first developer holding chamber D11 side, and the carbon powder can enter the second channel D7, and then be discharged from the main body D1 through the developer outlet D121. After the carbon powder in the first developer holding chamber D11 is pushed out, the elastic reset component D52 elastically recovers and pushes the third seal D51 upward to restore to the initial position of sealing the channel opening of the second channel D7 toward the first developer holding chamber D11 side. Preferably, the elastic reset component D52 is a compression spring, and optionally, the elastic reset component D52 can also be a tension spring, a spring sheet, an elastic rubber, an elastic sponge, etc.

[0378] Optionally, at least one powder inlet D511 is provided on the side wall of the third seal D51, and after the carbon powder enters the second channel D7, it can also enter the cavity of the third seal D51 through the powder inlet D511, and then enter the developer outlet D121 from the lower end opening of the third seal D51.

[0379] Optionally, the third sealing member D51 may also be a member in a rectangular parallelepiped, prism or other shape.

[0380] Optionally, the first one-way valve component D4 has a structure and principle similar to the above-mentioned second one-way valve component D5, and the first one-way valve component D4 is arranged in the first channel D6, the end of the third sealing member D51 away from the opening is toward the second developer containing chamber D2, and the elastic return member D52 is toward the first developer containing chamber D11.

[0381] Optionally, in a powder adding box 100, the first one-way valve component D4 can be set to the structure in Example 1, and the second one-way valve component D5 can be set to the structure in Example 2. Alternatively, the first one-way valve component D4 can be set to the structure in Example 2, and the second one-way valve component D5 can be set to the structure in Example 1. Alternatively, the first one-way valve component D4 and the second one-way valve component D5 can be both set to the structure in Example 1 or Example 2.

[0382] like Fig.70 As shown in the figure, as another variation of the fourteenth embodiment, different from the fourteenth embodiment, the powder adding box 100 in this embodiment further includes a third developer receiving chamber D13, which is arranged in the main body D1 and located between the first developer receiving chamber D11 and the developer outlet D121, and the third developer receiving chamber D13 is connected to the first developer receiving chamber D11 and the developer outlet D121 respectively. The channel connecting the first developer receiving chamber D11 and the third developer receiving chamber D13 is the second channel D7, and the second one-way valve member D5 is arranged in the second channel D7, so that the toner in the first developer receiving chamber D11 is unidirectionally transported to the third developer receiving chamber D13.

[0383] Alternatively, a second check valve member D5 may also be provided in the developer outlet D121.

[0384] Embodiment 15

[0385] like Fig.71 The existing developing box shown includes a developing part 210, a waste developer container 220 and a developer container 230 stacked in a vertical direction. The toner (developer) added by the toner box through the developer replenishing part 240 enters the developer container 230, enters the developer container 230 and is transferred to the front side of the developing box through multiple developer transmission components. The toner enters the developing part 210 through the developer supply channel 230-3, and the toner is then transferred to the developing roller 22 through multiple transmission components. However, in the developing box with such a structure, the outlet of the developer supply channel is easily blocked due to the accumulation of toner, thereby affecting printing. In order to solve these problems, this embodiment provides a developing box.

[0386] This embodiment provides a developing box, which can be detachably mounted to the main body of the imaging device, and the powder adding boxes of the above-mentioned embodiments 1 to 14 can be used to add developer to the developing box of this embodiment. Figure 72 to Figure 76 As shown, the developing box may include a developing part E1, a waste developer container E5 and a developer container E6. The developing part E1, the waste developer container E5 and the developer container E6 can be stacked in a vertical direction, and an optical path D is formed between the developing part E1 and the waste developer container E5. Exposure light passes through the optical path D to expose the photosensitive drum E11 of the developing part E1, and a developer supply channel E7 is set between the developing part E1 and the developer container E6 to enable the developer to be transported from the developer container E6 to the inside of the developing part E1.

[0387] like Fig.74 As shown, in some embodiments, the housing forming the exterior of the developing box may include a lower frame E12, an intermediate frame E51, and an upper frame E61. The developing part E1, the waste developer container E5, and the developer container E6 may be formed by the lower frame E12, the intermediate frame E51, and the upper frame E61, and the intermediate frame E51 may be provided with a recess E8 for generating a space for accommodating an optical scanner, and the optical scanner may be positioned in the recess E8. The lower frame E12 and the intermediate frame E51 are spaced apart in the vertical direction, so that an optical path D is formed between the developing part E1 and the waste developer container E5, and the optical path D through which the exposure light passes is formed between the lower frame E12 and the intermediate frame E51. The developing box also has a toner replenishment inlet E10, which is connected to the inside of the developing box, and the powder adding box may be connected to the toner replenishment inlet E10 to realize the addition of toner in the developing box; the toner replenishment inlet E10 may be provided on the side wall of the developing box.

[0388] like Fig.75 As shown, in this embodiment, the developing unit E1 includes a photosensitive drum E11 and a developing roller E13, the photosensitive drum E11 is a photoconductor that can form an electrostatic latent image, wherein the photosensitive drum E11 may include a cylindrical metal tube and a photoconductive layer with photoconductivity formed on the outer circumferential portion of the cylindrical metal tube, the developing unit E1 is provided with a charging roller E14 configured to charge the surface of the photosensitive drum E11 so that it has a uniform electric potential, a charging bias can be applied to the charging roller E14, the charging roller E14 charges the surface of the photosensitive drum E11, and the developing roller E13 supplies a developer to the electrostatic latent image formed on the surface of the photosensitive drum E11, and develops the electrostatic latent image into a developer image.

[0389] The developing roller E13 is rotatably disposed on one side of the photosensitive drum E11, and in the case of a two-component developing method using a developer and a carrier as a developer, the developing roller E13 may be in the form of a magnet fixedly mounted in a rotatable sleeve. The sleeve may be positioned to be separated from the photosensitive drum E11 by tens to hundreds of microns. The carrier may be attached to the outer periphery of the developing roller E13 due to the magnetic force of the magnet, and the developer may be attached to the carrier due to an electrostatic force, so that a magnetic brush including the carrier and the developer is formed on the outer periphery of the developing roller E13. Due to the developing bias applied to the developing roller E13, only the developer is transferred to the electrostatic latent image formed on the photosensitive drum E11.

[0390] In the case of a single-component developing method using a developer as a developer, the developing roller E13 may contact the photosensitive drum E11 or may be positioned to be separated from the photosensitive drum E11 by tens to hundreds of microns. In the present embodiment, a single-component contact developing method is adopted, in which the developing roller E13 and the photosensitive drum E11 contact each other to form a developing roller gap. The developing roller E13 may include a conductive metal core (not shown) and an elastic layer (not shown) formed on the outer peripheral portion of the conductive metal core (not shown). When a developing bias is applied to the developing roller E13, the developer is transported via the developing roller E13 and adheres to the electrostatic latent image formed on the surface of the photosensitive drum E11.

[0391] like Fig.74As shown, the developing box may also be provided with a supply roller E15, a cleaning component E52, and an adjusting component E16, a supply bias may be applied to the supply roller E15 to attach the developer to the developing roller E13, the adjusting component E16 may adjust the amount of the developer attached to the surface of the developing roller E13, and the cleaning component E52 may remove the residual developer and impurities from the surface of the photosensitive drum E11 before the photosensitive drum E11 is charged. Specifically, the adjusting component E16 may be an adjusting blade, the tip of which contacts the developing roller E13 with a predetermined pressure, and the cleaning component E52 may be a cleaning blade whose top end contacts the surface of the photosensitive drum E11, the tip of which contacts the photosensitive drum E11 with a predetermined pressure, and may remove impurities (waste developer) from the surface of the photosensitive drum E11. When the developing box is working, a charging bias is applied to the charging roller E14, and the photosensitive drum E11 is charged to have a uniform potential. The recess E8 is provided with a light scanner, and the light scanner irradiates light modulated according to image information onto the photosensitive drum E11 to form an electrostatic latent image on the surface of the photosensitive drum E11. The supply roller E15 attaches the developer to the surface of the developing roller E13. The adjusting component E16 forms a developer layer with uniform thickness on the surface of the developing roller E13. The developing bias is applied to the developing roller E13. The developer transported to the gap of the developing roller E13 due to the rotation of the developing roller E13 is transported and attached to the electrostatic latent image formed on the surface of the photosensitive drum E11 due to the developing bias, thereby forming a visible developer image on the surface of the photosensitive drum E11, so that the photosensitive drum E11 can be printed. After printing is completed, the residual developer on the surface of the photosensitive drum E11, which has not been transferred to the printing medium, can be removed by the cleaning component E52.

[0392] like Fig.74As shown, a rotatable conveying member E17 may also be provided in the developing section E1, and the length direction of the conveying member E17 (i.e., the direction of its own rotation axis) is parallel to the direction of the rotation axis of the developing roller E13. The developing section E1 includes a developing chamber E18 and a main hopper E19 located between the developing chamber E18 and the developer container E6. The conveying member E17 is disposed in the main hopper E19, and the conveying member E17 is disposed on one side of the supply roller E15. A developer supply channel E7 is provided between the developing section E1 and the developer container E6. In this embodiment, one is provided at each end of the developing section E1 in the length direction (i.e., the axial direction of the developing roller). The conveying member E17 is disposed at the outlet of the developer supply channel E7 (according to the flow direction of the developer, the developer supply channel E7 is connected to the developer container E6). One end is the entrance of the developer supply channel E7, and the end connected to the developing part E1 is the outlet of the developer supply channel E7, and the outlet of the developer supply channel E7 refers to the outlet of the developer supply channel and a partial area of ​​the developing part around the outlet). The conveying member E17 can rotate in the developing part E1, and the conveying member E17 can transport the developer along the length direction of the conveying member E17 and the rotation direction of the conveying member E17 (that is, the direction of the supply roller E15 and the developing roller E13), and transport the developer to the supply roller E15, and then the supply roller E15 transports the developer to the developing roller E13. Specifically, the conveying member E17 is a stirring member E171, and screw structures E172 are provided at both ends of the stirring member E171 in the length direction (i.e., the direction of its rotation axis), and the screw structures E172 at both ends are respectively located at the outlet of the developer supply channel E7, and threads are provided on the screw structure E172, and the threads of the screw structure E172 are arranged along the length direction of the rotating shaft, and stirring blades E173 are provided between the screw structures E172 at both ends. Preferably, the stirring member E171 may include a rotating shaft and a stirring blade E173 mounted on the rotating shaft, and the rotating shaft may be provided as a round shaft, a square shaft or other rotatable bar shaft. Optionally, when there is only one developer supply channel E7, the screw structure E172 may be provided only at the outlet of the developer supply channel E7.

[0393] The developing box also includes a driving force receiving mechanism for receiving driving force from the imaging device, and the rotating shaft can receive the driving force from the driving force receiving mechanism and rotate. When the stirring member E171 rotates, the screw structure E172 rotates, and the developer (which may be toner or particles used for developing) falling onto the screw structure E172 at the outlet of the developer supply channel E7 is transferred by the screw thread on the screw structure E172 along the direction of the rotation axis of the stirring member E171 toward the outlet of the developer supply channel E7, specifically toward the stirring blade E173 of the stirring member E171. The stirring blade E173 can be set to a rectangular, square, arc, wavy or other plate-like structure for stirring. The stirring blade E173 of this structure can be connected to the rotating shaft by welding, fixed to the rotating shaft by bolts, fixed to the rotating shaft by plugging, or integrated with the rotating shaft; optionally, the stirring blade E173 can be connected to the rotating shaft vertically or obliquely, and the stirring blade E173 can be provided with one or more pieces, and optionally, the stirring blade E173 is provided with two pieces, and the two stirring blades E173 are respectively arranged on both sides of the rotating shaft. When the stirring member E171 rotates, the stirring blade E173 rotates along the rotating direction of the stirring member E171, and the developer around it is transferred along the rotating direction of the stirring member E171 (that is, the developer is transferred toward the direction where the supply roller E15 and the developing roller E13 are located). The stirring member E171 of this structure can transfer the developer transferred by the screw structure E172 to the stirring blade E173 to the side of the developing roller E13, promote the flow of the developer, and avoid accumulation. In addition, the developer can be stirred by the stirring blade E173 and charged to have a predetermined potential. Optionally, the screw structure may not be set at the outlet, for example, it may be set away from the outlet, but the developer beside the outlet of the developer supply channel can be unblocked. Since the developer has a certain fluidity, when the developer beside the outlet of the developer supply channel is unblocked, the developer at the outlet of the developer supply channel will flow, so that the developer accumulated at the outlet of the developer supply channel is unblocked.

[0394] In this embodiment, two developer supply channels E7 are connected between the developing section E1 and the developer container E6. The two developer supply channels E7 are respectively located at the two ends of the stirring member E171. The screw structures E172 at the two end portions of the stirring member E171 are respectively arranged below the outlets of the two developer supply channels E7. When both ends of the rotating shaft in the length direction are provided with the screw structures E172, the stirring blades E173 are arranged between the first screw structures E172 at the two end portions. When the conveying member E17 conveys the developer to the developing roller E13 of the developing section E1, the threaded sections of the screw structures E172 at both ends in the length direction of the rotating shaft convey the developer toward the direction close to the stirring blades E173, so that the screw structures E172 at both ends of the stirring member E171 deliver the toner from the outlet of the developer supply channel to the middle of the two developer supply channels, thereby avoiding the accumulation of a large amount of toner at the outlet of the developer supply channel E7 and avoiding blockage.

[0395] The waste developer container E5 is located on the upper side of the developing section E1, the waste developer container E5 is spaced upward from the developing section E1, and an optical path D is formed between the waste developer container E5 and the developing section E1. The waste developer container E5 extends backward from the end portion near the photosensitive drum E11 beyond the length of the developing section E1, and the end portion has a cleaning member E52 mounted thereon, and the waste developer that can be removed from the photosensitive drum E11 by the cleaning member E52 is accommodated in the waste developer container E5. And, the concave portion E8 of the waste developer container E5 accommodating the optical scanner located at the rear of the developing section E1 may be defined by the developing section E1 having a length shorter than that of the waste developer container E5 and the waste developer container E5 located on the upper side of the developing section E1. For example, the waste developer container E5 may include a first portion E53 and a second portion E54 sequentially arranged from the vicinity of the photosensitive drum E11, and the first portion E53 may be arranged near the photosensitive drum E11 and mainly accommodate the waste developer. The second portion E54 corresponds to the recess E8 and can be positioned to be stepped upward than the first portion E53. The second portion E54 is connected to the first portion E53, and therefore, the second portion E54 has a shape that is inclined upward from the first portion E53 toward the second portion E54. The waste developer container E5 may further include a third portion E55, which is located behind the recess E8 and extends downward from the second portion E54. By doing so, the waste developer container E5 can obtain a larger space for accommodating waste toner.

[0396] The developer container E6 includes a storage portion E62 for accommodating developer. The storage portion E62 can be located in a position away from the developer supply portion in the rearward direction. For example, the storage portion E62 can be located above the third portion E55 of the waste developer container E5. The lower wall of the storage portion E62 can be partially embedded downward in the third portion E55, and the storage portion E62 can be formed into a shape complementary to the upper wall and protrude downward, by which a larger capacity of the storage portion E62 can be obtained. A conveying member E63 can also be provided in the developer container E6, and the conveying member E63 can convey the developer to the developer supply channel E7, and then the developer can be transported to the developing portion E1 through the developer supply channel E7.

[0397] When the device of the present invention is used, the developer is conveyed to the developer supply channel E7 by the conveying member E63 in the developer container E6, flows into the main hopper E19 of the developing section E1 through the developer supply channel E7, and conveyed to the developing roller E13 by the conveying member E17 in the main hopper E19, and then conveyed to the photosensitive drum E11 by the developing roller E13 for printing. In the process of conveying the developer, because the conveying member E17 is arranged to rotate in the developing section E1, the conveying member E17 can convey the developer along the length direction of the conveying member E17 to the direction away from the exit of the developer supply channel E7 and the rotation direction of the conveying member E17, thereby avoiding the developer at the exit of the developer supply channel E7 from being conveyed in time and causing the accumulation box to block the developer supply channel E7. At the same time, the developer can be delivered to the developing section E1, and the toner is conveyed faster, thereby avoiding the accumulation of a large amount of toner at the exit of the developer supply channel E7 and avoiding blockage.

[0398] like Fig.77As shown, as a variation of the fifteenth embodiment, a developing box is provided, which is different from the fifteenth embodiment in that: in this embodiment, the conveying member E17 is a first screw E174, and the rotation axis of the first screw E174 itself is arranged in parallel with the developing roller E13. One, two or more developer supply channels E7 can be provided between the developing part E1 and the developer container E6, and one, two or more first screws E174 can be provided. In this embodiment, the threads of the first screw E174 are arranged along the length direction of the first screw E174, and the threads of the first screw E174 are located at the outlet of the developer supply channel E7. The first screw E174 can receive the driving force from the driving force receiving member of the developing box to rotate. When the first screw E174 rotates, the thread of the first screw E174 rotates along the rotation direction of the first screw E174. When the developer falls on the thread, the developer is transferred on the thread of the first screw E174, so that the first screw E174 can transfer the developer along its length direction. Because of the rotation of the first screw E174, part of the developer falling on the first screw E174 is also transferred in the direction where the supply roller E15 and the developing roller E13 are located. The first screw E174 is provided with two sections of thread, and the directions of the two sections of thread are arranged oppositely. The two sections of thread of the first screw E174 are respectively located at the exits of the two developer supply channels E7 of the developing box, and the directions of the two sections of thread are arranged oppositely, so that the developer at the exit of the developer supply channel E7 is transferred on the first screw E174 along the direction of the middle position of the first screw. In some other embodiments, two first screws E174 are provided, the two first screws E174 are provided in the same axial direction, and the thread directions of the two first screws E174 are relatively provided, and the first screw E174 can be provided at the outlet of the developer supply channel E7, so that the developer below the developer supply channel E7 can be relatively transferred along the thread on the first screw E174, so that the developer at the outlet of the developer supply channel E7 is transported by the first screw E174, and in the transmission along the length direction of the conveying member E17, the first screw E174 transfers the developer at the developer supply channel E7 along the axial direction of the rotating shaft to the direction close to the middle position of the rotating shaft, thereby avoiding the accumulation of a large amount of toner at the outlet of the developer supply channel E7 and avoiding blockage; in addition, since the first screw E174 transfers the developer at the outlet of the developer supply channel E7 along the axial direction of the rotating shaft to the direction close to the middle position of the rotating shaft, the distribution of the developer in the length direction of the first screw E174 is more uniform.

[0399] like Fig.78As shown, as another variation of Example 15, another developer box is provided, which is different from Example 15 in that: in this embodiment, a powder detection device E9 is provided between the two developer supply channels E7. When the developer supply channel E7 is blocked or the toner has poor fluidity, the developer cannot flow from the outlet of the developer supply channel E7 to the position detected by the powder detection device E9, and the printer displays a powder shortage signal, but in fact there is still toner in the developing section. In this embodiment, the conveying member E17 is provided as an attachment to the powder detection device, so that the conveying member E17 can transfer the developer to the vicinity of the powder detection device E9, so as to avoid inaccurate detection by the powder detection device E9 and affect printing.
