Description

Toner bottle, toner bottle connecting structure, developing device and printing equipment Technical Field

[0001] The present application relates to the field of laser printing, and in particular to a toner bottle, a toner bottle connection structure, a developing device and a printing device. Background Art

[0002] In the prior art, laser printers and copiers generally include a developing device and a fixing device. The developing device is used to transfer the image to the print medium, while the fixing device is used to fix the image to the print medium. The developing device comprises a main body, which includes a housing and, housed within it, a photosensitive drum, a cleaning roller, a charging module, a developing roller, and a stirring element. The cleaning roller is used to clean residual toner from the photosensitive drum; the charging module is used to uniformly charge the photosensitive drum; the housing is provided with a light passage for introducing selective light to form a latent image on the photosensitive drum through the photoelectric effect; the developing roller is used to apply toner to the photosensitive drum according to the latent image to form an image; the photosensitive drum is used to transfer the image formed by the toner to the print medium; and the stirring element is used to stir the toner within the housing and transfer it to the developing roller. In the prior art, toner bottles can be replaced by being inserted into and removed from the main body. However, in the prior art, toner bottles are typically inserted into and removed from the main body perpendicular to their extension, resulting in a large opening in the main body, making it easy for foreign matter to enter and cause malfunction. Summary of the Invention

[0003] The purpose of this application is to overcome the above-mentioned defects or problems existing in the background technology, and to provide a toner bottle, a toner bottle connecting structure, a developing device and a printing device, wherein the toner bottle is suitable for being installed into or removed from the main body of the developing device along its extension direction, so that the opening on the main body is smaller and foreign matter is not easy to enter the main body and cause main body failure.

[0004] In order to achieve the above objectives, the following technical solutions are adopted:

[0005] As one embodiment of the present application, a toner bottle is provided for dispensing toner into a housing containing the toner bottle. The toner bottle extends in a first direction and includes a cover at a front end thereof. The cover is adapted to be fixed relative to the housing to dispense toner into the housing. The toner bottle is characterized in that an operating unit is provided at the front end of the cover. The operating unit has at least two operating portions adapted to be directly contacted by different fingers of the same hand, with the at least two operating portions facing away from each other to facilitate operation by a thumb or any other finger. The operating unit has at least two operating portions adapted to be directly contacted by different fingers of the same hand, with the at least two operating portions facing away from each other to facilitate operation by a thumb or any other finger, enabling different fingers of the same hand to operate each operating portion. This allows the operating unit to be placed in and out of the toner bottle within a relatively small operating space. Because the cover is positioned at the front end of the toner bottle in the first direction and the operating unit is positioned at the front end of the cover, the toner bottle can be operated from the end thereof by finger operation, thereby enabling the toner bottle to be inserted into the housing along its extending direction. This reduces the opening of the housing and prevents objects from entering the housing and causing malfunctions.

[0006] As one solution of the present application, a toner bottle connection structure is provided, wherein the toner bottle is adapted to be detachably connected to a main body of a developing device and to supply toner to the main body. The toner bottle comprises a bottle portion and a cover, the cover being located in front of the bottle portion in a first direction and configured to discharge toner to the main body. The bottle portion is rotatably connected to the cover, with its rotation axis extending in the first direction. The main body comprises a housing and a bottle portion drive assembly, the housing being adapted to receive the toner bottle in a second direction, opposite to the first direction, to accommodate the toner bottle. The housing is adapted to be fixedly connected to the cover after the toner bottle is fully inserted. The bottle portion drive assembly is located behind the bottle portion and rotates relative to the housing about the rotation axis. The bottle portion drive assembly is adapted to engage with the bottle portion to prevent rotation after the toner bottle is fully inserted. The direction in which the toner bottle is inserted into the main body is aligned with the direction of its rotation axis. Therefore, the main body opening is small, making it difficult for foreign matter to enter the main body and cause main body malfunction. The bottle driving assembly for driving the bottle to rotate and the cover for outputting toner are respectively located at the two ends of the bottle along the first direction, which significantly improves the influence of vibration caused by the joint rotation of the bottle driving assembly and the bottle anti-rotation cooperation on the output of toner by the cover, so that the loose sealing caused by vibration when the toner is output from the toner bottle to the main body can be improved.

[0007] The conveying member as a solution of the present application is used to be connected to a bottle body suitable for accommodating and conveying toner, so as to obtain toner from the bottle body and continue to convey it; the bottle body extends along a first direction and is provided with a bottle mouth portion in front and a bottle body portion in the rear, and the bottle body portion is provided with a spiral groove to convey the toner along the first direction when the bottle body rotates along the first rotation direction; the conveying member is suitable for being fixed relative to the bottle body in the first direction and rotating with the bottle body along the first rotation direction, and the conveying member is provided with: an annular wall, which is suitable for being inserted into the bottle mouth portion backward; a first baffle, whose front end extends out of the annular wall along the first direction, and whose inner edge extends inwardly into the inner edge of the annular wall; and a spiral protrusion, which protrudes inwardly from the inner surface of the annular wall in a spiral shape, and is configured to convey the toner along the first direction when the conveying member rotates with the bottle body, the front surface of the rear end of the spiral protrusion is connected to the front end of the spiral groove, and its front end faces away from the first rotation direction toward the first baffle. The front surface of the spiral protrusion of the conveying member engages the spiral groove, allowing toner moving in the first direction to continue to move in the first direction on the conveying member, propelled by the spiral protrusion. The front end of the spiral protrusion faces away from the first rotational direction toward the first baffle, allowing the first baffle to receive toner that falls from the front end of the spiral protrusion. This facilitates efficient transfer of residual toner from the bottle to the first baffle when the amount of toner in the bottle is low, and then transported to the powder delivery port via the first baffle, thereby avoiding waste.

[0008] As a solution of the present application, a developing device includes a main body, which includes a shell and a photosensitive drum, the shell contains toner, and the photosensitive drum transfers the image formed by the toner to the printing medium by rotating relative to the shell; and a toner bottle, which is used to supply toner to the shell and is suitable for being detachably connected to the shell for easy replacement, and includes a cover body and a bottle part that are connected to each other, the cover body is fixed relative to the shell and is provided with a powder feeding port for outputting toner to the shell, the bottle part rotates relative to the cover body around a rotation axis to convey the toner it contains to the cover body, wherein the powder feeding port is located on one side of the plumb plane where the rotation axis is located, and the bottle part also lifts the toner to the powder feeding port by rotation, and the bottle part and the photosensitive drum are linked to each other. The powder feeding port is located on one side of the plumb plane where the rotation axis of the bottle is located, that is, the powder feeding port is arranged laterally, and the toner is no longer fed out of the powder feeding port by gravity. The powder holding chamber of the main body that holds the toner no longer needs to be placed below the toner bottle, thereby reducing the thickness of the developing device in the vertical direction, which is conducive to the miniaturization of the printing equipment.

[0009] As a solution of the present application, a developing device includes a main body and a toner bottle; the toner bottle is suitable for moving along a first direction to be taken out of the main body and suitable for moving along a second direction away from the first direction to be loaded into the main body; the main body includes a shell, the shell is provided with a bottle cavity for accommodating the toner bottle, the bottle cavity extends along the first direction; a powder inlet is provided on the cavity wall of the bottle cavity, the shell is provided with a forward blocking portion in front of the powder inlet, and the shell is provided with a backward stopping portion in front of the blocking portion; the toner bottle extends along the first direction and includes a cover portion and a bottle portion connected to each other, the cover portion includes a cover body and a sliding cover, and the side wall of the cover body is provided with a powder feeding The sliding cover is adapted to slide relative to the cover body in a first direction to open the powder feeding port and slide in a second direction to close the powder feeding port. The sliding cover is provided with a blocking portion adapted to cooperate with the blocking portion and a retracting portion adapted to cooperate with the retracting portion. The blocking portion is configured to abut the blocking portion forwardly when the toner bottle moves in the second direction within the bottle chamber, causing the sliding cover to slide relative to the cover body in the first direction until the powder feeding port is opened. The retracting portion is configured to abut the retracting portion backwardly when the toner bottle moves in the first direction within the bottle chamber, causing the sliding cover to slide relative to the cover body in the second direction until the powder feeding port is closed. The toner bottle is inserted into and removed from the body along its extending direction, so the opening in the body is relatively small, making it difficult for foreign matter to enter the body and cause malfunctions. During the process of inserting the toner bottle into the body, the blocking portion abuts the blocking portion, causing the sliding cover to open the powder feeding port, thereby preventing powder leakage during the insertion process. When the toner bottle is taken out from the body, the sliding cover closes the powder feeding port by the stop portion abutting against the stop fitting portion, thereby preventing powder leakage during the taking out process.

[0010] As a solution of the present application, a developing device includes a body and a toner bottle; the toner bottle is suitable for moving along a first direction to be taken out of the body and suitable for moving along a second direction away from the first direction to be loaded into the body; the body includes a shell and a cover, the shell is provided with a bottle cavity for accommodating the toner bottle, the bottle cavity extends along the first direction; a powder inlet is opened on the cavity wall of the bottle cavity, the cover is suitable for sliding relative to the shell in the first direction to close the powder inlet and sliding along the second direction to open the powder inlet; the toner bottle extends along the first direction and includes a cover portion connected to each other The cover comprises a cover body, a powder feeding port being provided on a side wall of the cover body, a rearward-facing pushing portion being provided on the cover body behind the powder feeding port, and a forward-facing pulling portion being provided on the cover body behind the pushing portion.

The pulling portion is configured to pull against the cover when the toner bottle moves in a first direction within the bottle cavity, causing the cover to slide relative to the housing in the first direction to close the powder feeding port. The pushing and pulling portions provided on the cover body enable the cover to open and close the powder feeding port, effectively preventing toner contained in the housing from leaking from the powder feeding port into the bottle cavity during the process of loading the toner bottle into the main body.

[0011] As a solution of the present application, the main body is used to receive the toner supplied by the toner bottle and output the pattern formed by the toner to the printing medium; it is characterized in that it is also used to accommodate the integrated circuit board loaded along the second direction with the toner bottle and extract the information related to the toner bottle stored in the integrated circuit board; the main body includes a shell and an information extraction member, the shell is provided with a board holding rack, a bottle holding cavity and a recovery cavity; the board holding rack is used to accommodate the integrated circuit board, the bottle holding cavity is used to accommodate the toner bottle, and the recovery cavity is used to recover the integrated circuit board; the board holding rack is adjacent to the bottle holding cavity and is provided with a stopper, a clearance space, a first elastic claw and a holding cavity The board cavity; the stop portion extends along the first direction away from the second direction, and the stop portion is adjacent to the inner side of the bottle cavity to form the makeshift space, and the first elastic claw is located on the outer side of the stop portion, and its claw body extends along the first direction, and its claw head is arranged inward and backward; a board cavity suitable for accommodating two integrated circuit boards arranged along the first direction is formed between the stop portion and the first elastic claw, and the board frame is provided with a supporting wall at the front of the board cavity to support the integrated circuit board, and the rear part of the board cavity is downwardly connected to the recovery cavity; the information extraction component is suitable for extracting information recorded on the integrated circuit board located at the front of the board cavity.

The integrated circuit board is used to store information related to a toner bottle. The toner bottle is used to supply toner to the main body of the developing device and to carry the integrated circuit board. When the toner bottle is loaded into the main body, the integrated circuit board is transferred to the main body; when the toner bottle is removed from the main body, the integrated circuit board is left in the main body to form a plate to be recycled; when a new toner bottle is loaded into the main body, the integrated circuit board corresponding to the new toner bottle is transferred to the main body, and the plate to be recycled is pushed into the recycling chamber in the main body for easy recycling. The method for recycling integrated circuit boards of one solution of the present application can realize the recycling of integrated circuit boards, which not only avoids waste, but also facilitates determining whether an unauthorized toner bottle is used to replenish toner by analyzing the model of the integrated circuit board and the stored information, and based on this, determining a specific plan for repairing the printing device.

[0080] The technical solutions in the embodiments will be described clearly and completely below with reference to the accompanying drawings.

[0081] Example 1

[0082] The developing device 1 is used to receive the selective light signal and selectively apply toner to transfer the image represented by the selective light signal to a print medium via a photosensitive drum. Generally, the developing device 1 is primarily used in printing devices, such as laser printers or copiers, as long as they can generate an image formed by toner on a print medium.

[0083] Referring to Figure 1 , a developing device 1 in this embodiment is shown. As shown in Figure 1 , the developing device 1 includes a main body 2, a toner bottle 3, and an integrated circuit board 4. The main body 2 is used to implement the functions of the developing device 1 and to accommodate the toner bottle 3 and the integrated circuit board 4. The toner bottle 3 is used to supply toner to the main body 2. In this embodiment, the toner bottle 3 is replaceable, meaning that the toner bottle 3 can be easily loaded and unloaded from the main body 2. Specifically, the toner bottle 3 moves along at least a second direction Y during loading into the main body 2, and moves along at least a first direction Z during unloading from the main body 2. The integrated circuit board 4 provides information related to the toner bottle 3 to the main body 2. This information may include anti-counterfeiting information and / or toner capacity information of the toner bottle 3. The integrated circuit board 4 is removably attached to the toner bottle 3 when the toner bottle 3 is not loaded into the main body 2. During loading, the integrated circuit board 4 moves with the toner bottle 3 and ultimately connects to the main body 2. During the removal of the toner bottle 3 from the main body 2, the integrated circuit board 4 remains on the main body 2, forming a recovery plate 4'. When the toner bottle 3 is replaced, the new integrated circuit board 4 pushes against the recovery plate 4' as the toner bottle 3 is inserted into the main body 2, causing it to move and be accommodated within the main body 2, thereby enabling the recovery of the toner bottle 3 or identifying unauthorized use. The structure and shape of the integrated circuit board 4 in the developing device 1 are well known to those skilled in the art and do not involve improvements related to this patent, so they will not be described in detail below.

[0084] Referring to Figures 2 and 3, the main body 2 of this embodiment is shown. As shown in Figures 2 and 3, the main body 2 includes a housing 5, a cover 6, a photosensitive drum 7, a cleaning element 8, a charging module 9, a developing roller 10, an intermediate roller 11, a stirring element 12, a drive mechanism 13, and an information extraction element 14 (shown in Figure 43). The housing 5 houses and supports the other components of the main body 2. The structure, connections, and function of the cover 6 are described in detail below. The photosensitive drum 7 rotates relative to the housing 5. After being uniformly charged by the charging module 9, it receives a selective light signal input from a light port 24 on the housing 5 and forms a latent image through the photoelectric effect. The photosensitive drum 7 also receives toner applied by the developing roller 10 based on the latent image and transfers the image formed by the toner to the print medium. In this embodiment, the photosensitive drum 7 is exposed below the housing 5 to contact the print medium and transfer the image. In this embodiment, "exposed" means that an object is at least partially not obscured by the housing 5, is directly visible to the naked eye, and can contact or cooperate with components outside the developing device 1. The cleaning member 8 is used to clean the residual toner on the photosensitive drum 7. The charging module 9 is used to uniformly charge the photosensitive drum 7. The developing roller 10 rotates relative to the housing 5 and is used to apply toner to the photosensitive drum 7 to form an image according to the latent image. The intermediate roller 11 rotates relative to the housing 5 and is used to cooperate with the developing roller 10. The stirring member 12 is used to stir and transport the toner contained in the housing 5. The driving mechanism 13 is installed in the housing 5 and is used to drive the various moving parts of the developing device 1 to rotate relative to the housing 5. The information extraction member 14 is used to extract information from the integrated circuit board 4 so that other modules installed inside the housing 5 can extract and use the information recorded on the integrated circuit board 4. In this embodiment, the information extraction member 14 uses an elastic electrical connection terminal. In other embodiments, the information extraction member can also use a non-contact information extraction method, such as NFC. In the main body 2, the structures and principles of the photosensitive drum 7, cleaning element 8, charging module 9, developing roller 10, intermediate roller 11, stirring element 12 and information extraction element 14 are well known to those skilled in the art and do not involve improvements related to this patent, so they will not be described in detail below.

[0085] Referring to Figures 4 to 9 and 43, Figures 4 to 9 illustrate the housing 5 and cover 6 in this embodiment. Figure 43 illustrates the information extraction member 14 in this embodiment. As shown in Figures 4 and 5, the housing 5 includes an upper housing 15 and a lower housing 16. The upper housing 15 and the lower housing 16 are detachably fixedly connected and form a bottle chamber 17, a powder chamber 18, a functional chamber 19, and a guide channel 20. As shown in Figure 4, the bottle chamber 17 extends along the second direction Y and is used to accommodate the toner bottle 3. A bottle insertion opening 21 is provided at the front end of the bottle chamber 17. The bottle insertion opening 21 is used to allow the toner bottle 3 to be inserted into the bottle chamber 17 along the second direction Y. In this embodiment, "front" refers to the front position along the first direction Z, and "rear" refers to the rear position along the first direction Z. The powder chamber 18 is used to accommodate toner, the stirring member 12, and other components. The powder chamber 18 is connected to the bottle chamber 17 via a powder inlet 22. The powder inlet 22 is used to introduce toner from the toner bottle 3 into the powder chamber 18. The functional chamber 19 is adjacent to the powder holding chamber 18 and is used to accommodate components such as the photosensitive drum 7 and the developing roller 10. As shown in Figure 5, a guide channel 20 is located at the front end of the housing 5 and communicates with the bottle holding chamber 17. The guide channel 20 is used to guide the toner bottle 3 during installation and removal from the housing 2. In this embodiment, the guide channel 20 has a Z-shaped structure and consists of a first channel, a second channel, and a third channel that are interconnected in sequence. The first channel is located at the front of the guide channel 20 and extends along the second direction Y. Its front end is open and its rear end connects to the second channel. The second channel is located in the middle of the guide channel 20 and extends perpendicular to the second direction Y. Its first end connects to the first channel and its second end connects to the third channel. As shown in Figures 4 and 5, the third channel is located at the rear of the guide channel 20 and extends along the second direction Y. Its front end connects to the second channel and its rear end extends into the housing 5 and stops at a stopper 23. As shown in Figure 4, the upper housing 15 is provided with a light aperture 24. The light opening 24 extends along the second direction Y and is used to allow selective light to pass through and illuminate the uniformly charged photosensitive drum 7. The lower housing 16 includes a lower housing body 25, a front cover 26, a rear cover 27, and a base plate 28, which are fixedly connected to each other. The lower housing body 25 is provided with a first mating portion 29, a guide rail 30, a blocking portion 31, a stopper 32, and a plate holder 33. The first mating portion 29 is located in the bottle cavity 17 and is used to mate with the toner bottle 3, securing the toner bottle 3 relative to the housing 5 along the second direction Y and the first direction Z. In this embodiment, the first mating portion 29 is designed as a hole. In other embodiments, the first mating portion 29 can also be configured as a groove or an inward protrusion from the wall of the bottle cavity 17. In this embodiment, "inward" refers to the direction toward the rotation axis of the bottle portion 49 in the toner bottle 3, and "outward" refers to the direction away from the rotation axis of the bottle portion 49. There are two guide rails 30, both of which extend along the second direction Y. Along the circumferential direction, the powder inlet 22 is located between the two guide rails 30. The two guide rails 30 are used to cooperate with the cover 6 so that the cover 6 can slide relative to the housing 5 along the second direction Y and the first direction Z.The blocking portion 31 is located in front of the powder inlet 22 and has a forward-facing blocking surface. The stopper portion 32 is located in front of the blocking portion 31 and has a rearward-facing stopper surface. The plate holder 33 is located at the front end of one side of the bottle holding chamber 62 and is used to accommodate the integrated circuit board 4 connected to the body 2. As shown in Figures 6 to 8, the plate holder 33 is provided with a stopper portion 34, a clearance space 35, a first elastic claw 36, and a plate holding chamber 37. The stopper portion 34 is located at the rear of the plate holder 33 and extends along the first direction Z. The clearance space 35 is formed inside the stopper portion 34. The first elastic claw 36 is located outside the stopper portion 34 and is used to prevent the integrated circuit board 4 from leaving the body 2 when the toner bottle 3 is removed from the body 2. The claw body of the first elastic claw 36 extends along the first direction Z. The claw head is located at the front end of the claw body and has a claw surface facing inward and backward. The front surface of the claw head is inclined outward along the first direction Z. A board cavity 37 is formed between the stopper 34 and the first elastic claw 36. The board cavity 37 is used to accommodate the integrated circuit board 4 and provide a passage for the board 4' to be retrieved. The board cavity 37 is divided into a front portion and a rear portion along a first direction Z. The board frame 33 is provided with a support wall below the front portion of the board cavity 37 to support the integrated circuit board 4 as it enters the front portion of the board cavity 37. In this embodiment, "upper" refers to a direction vertically away from the center of the Earth, and "lower" refers to a direction vertically closer to the center of the Earth. As shown in Figure 43, the information extraction component 14 extends into the front portion of the board cavity 37 and is resilient. Its front end is formed with an inclined surface to elastically deform when the integrated circuit board 4 enters the front portion of the board cavity 37, pressing against the input and output terminals on the integrated circuit board 4, thereby establishing electrical connections between other modules and the integrated circuit board 4. The rear portion of the board cavity 37 provides a passage for the board 4' to be retrieved. As shown in Figure 4, the front cover 26 is located at the front end of the lower housing 16 and is fixedly connected to the lower housing body 25. As shown in Figures 2, 4 and 9, a recovery chamber 38 is provided between the lower shell body 25 and the front cover 26. Along the first direction Z, the recovery chamber 20 is located in front of the powder holding chamber 18 and is isolated from the powder holding chamber 18. Along the up-down direction, the recovery chamber 38 is located below the rear portion of the plate holding chamber 37 and is connected to the rear portion of the plate holding chamber 37 along the up-down direction for the plate 4' to be recovered to fall into the recovery chamber 38. In this embodiment, the front cover 26 is at least partially adapted to be detachably fixed to the lower shell body 25 so that the plate 4' to be recovered accommodated in the recovery chamber 38 can be easily recovered. As shown in Figure 4, the rear cover 27 is located at the rear end of the lower shell body 16 and is fixedly connected to the lower shell body 25. The base plate 28 is fixed to the front of the rear cover 27 and is spaced apart from the rear cover 27.

[0086] As shown in Figures 4 and 5, the cover 6 is engaged with the two guide rails 30, allowing the cover 6 to slide relative to the housing 5 in the second direction Y to open the powder inlet 22 and in the first direction Z to close the powder inlet 22. The outer side of the cover 6 is provided with an elastic sealing portion adapted to closely contact the wall of the bottle receiving chamber 17, thereby preventing toner contained in the powder receiving chamber 18 from leaking into the bottle receiving chamber 17 when the cover 6 closes the powder inlet 22.

[0087] Referring to Figures 10 to 14 , the drive mechanism 13 in this embodiment is shown. As shown in Figures 2 and 10 , the drive mechanism 13 includes a first rotating member 39, a bottle drive assembly 40, and a transmission assembly 41. The first rotating member 39 is used to rotate the photosensitive drum 7. In this embodiment, the first rotating member 39 is a gear, with its lower portion exposed from the lower housing 25 to engage with an external gear and obtain external driving force. In this embodiment, the first rotating member 39 is the only power input for the drive mechanism 13. The bottle drive assembly 40 is used to rotate the bottle portion 49 of the toner bottle 3. As shown in Figure 11 , the bottle drive assembly 40 includes a second rotating member 42, a sliding connector 43, an energy storage member 44, a stopper 45, and a fastener 46. As shown in Figures 12 to 14 , the second rotating member 42 includes a rotating portion 47 and a rotating shaft 48. In this embodiment, the rotating portion 47 is a gear and is sandwiched between the rear cover 27 and the base plate 28. The rotating shaft portion 48 is fixedly connected to the rotating portion 47 and supported by the rear cover 27 and the base plate 28. The front portion of the rotating shaft portion 48 extends out of the base plate 28 in the first direction Z and is provided with radial projections in the radial direction. The sliding connector 43 is sleeved on the front portion of the rotating shaft portion 48 and is provided with radial grooves adapted to engage with the radial projections for anti-rotation. Of course, the sliding connector 43 and the rotating shaft portion 48 can also achieve anti-rotation engagement through other non-rotational surface engagement methods. In this embodiment, "anti-rotation engagement" refers to a non-rotational surface engagement between the two, preventing relative movement in the direction of rotation. The sliding connector 43 is adapted to slide relative to the second rotating member 42 in both the second direction Y and the first direction Z, and remains anti-rotationally engaged with the second rotating member 42 during sliding. In this embodiment, the energy storage member 44 is an elastic member positioned between the sliding connector 43 and the base plate 28 in the second direction Y. Its function is to store energy when the sliding connector 43 moves in the second direction Y, and to release this energy to propel the sliding connector 43 in the first direction Z. In some embodiments, the energy storage member 44 can be an elastic member positioned between the sliding connector 43 and the second rotating member 42. In other embodiments, the energy storage member 44 can be a magnetic member, providing a magnetic interaction with the sliding connector 43. This can also achieve the function of storing energy when the sliding connector 43 moves in the second direction Y and releasing energy to propel the sliding connector 43 in the first direction Z. When the energy storage member 44 is a magnetic member, the energy storage member 44 is generally fixed to the housing 4 or the second rotating member 42. The stop member 45 is used to limit the sliding travel of the sliding connector 43 in the first direction Z, preventing it from disengaging from the rotating shaft portion 48. The stop member 45 is fixed to the rotating shaft portion 48. In this embodiment, the stop member 45 is fixed to the front end of the rotating shaft portion 48 by a fastener 46. Specifically, the front end of the rotating shaft portion 48 has a threaded hole, and the fastener 46 is a screw. The fastener 46 passes through the stop member 45 and screws into the threaded hole of the rotating shaft portion 48, thereby fixing the stop member 45 to the front end of the rotating shaft portion.The transmission assembly 41 is used to transmit power from the first rotating member 40 to the second rotating member 42 on the one hand, and on the other hand, it also drives at least the stirring member 12 to rotate inside the powder holding chamber 18. In this embodiment, the transmission assembly 41 includes a plurality of transmission gears meshed in sequence, the input end of which is meshed with the first rotating member 40, and the output end of which is meshed with the rotating portion 47. In other embodiments, the first rotating member 39, the transmission assembly 41 and the second rotating member 42 can be designed as any transmission mechanism well known to those skilled in the art, such as a pulley transmission mechanism, as long as the linkage of the first rotating member 40 and the second rotating member 42 is achieved. The linkage of the first rotating member 40 and the second rotating member 42 means that the photosensitive drum (7) and the bottle portion (49) are linked to each other. In this embodiment, "linkage" means that two objects move and stop at the same time through mechanical or other connection methods, and can move in the same direction or in opposite directions, and can move at the same speed or at different speeds.

[0088] Referring to Figure 15 , it illustrates the toner bottle 3 and integrated circuit board 4 in this embodiment. The toner bottle 3 is used to store, transport, and supply toner to the powder inlet 22, and also supports the integrated circuit board 4. As shown in Figure 15 , the toner bottle 3 includes a cover 50 in addition to a bottle portion 49. The bottle portion 49 is used to store and transport toner. The cover 50 is used to supply toner to the powder inlet 22 and support the integrated circuit board 4. In this embodiment, after the bottle portion 49 and cover 50 are connected, they are adapted to rotate relative to the cover 50 in a first rotational direction ω.

[0089] Referring to Figures 16 to 24 , the bottle portion 49 of this embodiment is shown. As shown in Figure 16 , the bottle portion 49 includes a bottle body 51, a conveying member 52, and a sealing member 53. The bottle body 51 is typically manufactured by a blow molding process and is used to contain and convey toner along a first direction Z. As shown in Figures 17 and 18 , the bottle body 51 extends along a second direction Y and includes an integrally connected bottle mouth portion 54 and a bottle body portion 55. The bottle mouth portion 54 includes an integrally connected bottle mouth ring wall 56, a bottle mouth flange 57, and a bottle mouth end wall 58. The bottle mouth ring wall 56 is annular in shape, with its central axis aligned with the rotational axis of the bottle portion 49 and both extending along the first direction Z. The bottle mouth flange 57 is annular in shape and protrudes outward from the rear end of the bottle mouth ring wall 56. The bottle mouth end wall 58 is annular in shape and protrudes inward from the front end of the bottle mouth ring wall 56. The hollow portion of the bottle mouth end wall 58 forms the bottle mouth. The body portion 55 extends along the second direction Y. Its front portion, near the bottle mouth 54, tapers along the first direction Z to connect with the rear end of the bottle mouth ring wall 56. The inner surface of the front portion of the body portion 55 is provided with two inwardly projecting stopper protrusions 59, spaced evenly along the first rotational direction ω. The inner surface of the body portion 55 is provided with two inwardly projecting spiral protrusions 60, the central axes of which extend along the first direction Z and rotate in the same direction. The space between each spiral protrusion 60 or between two adjacent spiral protrusions 60 forms a spiral groove 61, which extends from the rear end of the body portion 55 to the front end of the body portion 55 near the bottle mouth 54. The spiral protrusions 60 are configured such that when the bottle portion 49 rotates in the first rotational direction ω, toner is transported from rear to front in the spiral groove 61 along the first direction Z. The rear end surface of the body portion 55 is provided with a bottom groove 62, which extends radially and opens rearward. The bottle bottom groove 62 is configured to allow the stopper 45 to extend from its opening in the first direction Z. When the sliding connector 43 rotates in the same or similar phase as the bottle bottom groove 62, the bottle bottom groove 62 is also configured to allow the sliding connector 43 to extend from its opening in the first direction Z, thereby preventing the sliding connector 43 from rotating with the bottle body 51. The conveying member 52 is adapted to be connected to the bottle body 51. The conveying member 51 is used to convey toner within the bottle body 51 to the cover 49. As shown in Figures 19 and 20, the conveying member 52 includes an annular wall 63, an abutting flange 64, a first stopper 65, a second stopper 66, an abutting protrusion 67, a latching protrusion 68, and a spiral protrusion 69. The annular wall 63 is annular in shape, with its central axis extending in the first direction Z. It is adapted to be inserted into the bottle body 51 from the bottle mouth. The abutting flange 64 is annular in shape, protruding outward from the front end of the annular wall 63 and adapted to abut the front surface of the bottle mouth end wall 58 in the second direction Y. The first stopper 65 is used to output the toner to the cover 50 when the bottle portion 49 rotates along the first rotation direction ω.A first baffle 65 is disposed at the front of the conveyor member 52 and extends along the first direction Z. The front end of the first baffle 65 extends along the first direction Z to abut the flange 64, while the rear end of the first baffle 65 extends into the interior of the annular wall 63. In other embodiments, the rear end of the first baffle 65 may also rest on the front surface of the abutting flange 64. In a cross-section perpendicular to the first direction Z, the outer edge of the first baffle 65 engages the outer edge of the abutting flange 64, while the inner edge of the first baffle 65 extends inward into the inner edge of the annular wall 63. In this embodiment, there are two first baffles 65, evenly spaced along the first rotational direction ω. The second baffle 66 assists in stirring the toner to prevent it from clumping. The second baffle 66 is disposed at the front of the conveyor member 52 and extends along the first direction Z from the front surface of the abutting flange 64. In a cross-section perpendicular to the first direction Z, the outer edge of the second baffle 66 engages the outer edge of the abutting flange 64, while the inner edge of the second baffle 66 engages the inner edge of the annular wall 63. In this embodiment, there are four second baffles 66, divided into two groups of two. The two second baffles 66 in a group are located on either side of the two first baffles 65 and are evenly spaced between the two first baffles 65 along the first rotational direction ω. In this embodiment, each first baffle 65 and each second baffle 66 is provided with reinforcing ribs on the back surface facing away from the first rotational direction ω. Abutment protrusions 67 project rearwardly from the rear end of the annular wall 63 along the second direction Y. There are four abutment protrusions 67, divided into two groups of two. The two abutment protrusions 67 in a group are evenly spaced along the first rotational direction ω, forming a phase angle between the two groups of abutment protrusions 67. This phase angle can preferably be 90 degrees, or other angles. Each group of two abutment protrusions 67 is configured to abut and engage with the two stop protrusions 59, respectively, so that when the bottle body 51 is driven by the bottle drive assembly 40 to rotate in the first rotational direction ω, it can push the conveyor 52 to rotate along the first rotational direction ω. The latching protrusion 68 protrudes outward from the outer surface of the annular wall 63 and is located behind the abutting flange 64. The gap between the rear surface of the abutting flange 64 and the front surface of the latching protrusion 68 is adapted to the thickness of the bottle end wall 58. When the conveying member 52 is connected to the bottle body 51, the bottle end wall 58 is sandwiched between the abutting flange 64 and the latching protrusion 68, preventing the conveying member 52 from moving relative to the bottle body 51 in the first direction Z. The spiral protrusion 69 is used to convey toner from the spiral groove 61 to the first baffle 65. The spiral protrusion 69 is formed to protrude inwardly from the inner surface of the annular wall 63 in a spiral shape. The spiral direction is configured such that when the bottle body 49 rotates in the first rotational direction ω, the toner is pushed by the spiral protrusion 69 and moves in the first direction Z. In this embodiment, the number of spiral protrusions 69 matches the number of first baffles 65 and corresponds one-to-one. The front surface of the spiral protrusion 69 is directed toward the first baffle 65 in a direction away from the first rotation direction ω. That is, when the bottle portion 49 rotates along the first rotation direction ω, the toner pushed by the front surface of the spiral protrusion 69 falls onto the first baffle 65 located below under the action of gravity when it separates from the front end of the spiral protrusion 69.As shown in FIG16 , the sealing member 53 is annular in shape with a thickness and exhibits elasticity at least in the first direction Z. The inner edge of the sealing member 53 is adapted to abut against the outer surface of the bottle finish ring wall 56, and the rear surface of the sealing member 53 is adapted to abut against the front surface of the bottle finish flange 57. In this embodiment, the sealing member 53 is attached to the bottle body 51 by being positioned over the bottle finish ring wall 56, with the rear surface of the sealing member 53 abutting against the front surface of the bottle finish flange 57. The conveying member 52 is attached to the bottle body 51 by inserting the conveying member 52 into the bottle body 51 along the second direction Y, with the abutting protrusion 67 facing the bottle finish, until the bottle finish end wall 58 is sandwiched between the abutting protrusion 64 and the retaining protrusion 68. The bottle body 51 is then rotated relative to the conveying member 52 in the first rotational direction ω, causing the stop protrusion 59 to abut against the abutting protrusion 67 in the first rotational direction ω. The two sets of abutment protrusions 67 in this embodiment are designed to reduce the angle at which the conveyor 52 can be rotated relative to the bottle body 51 during assembly of the bottle body 51 and the conveyor member 52, thereby improving assembly efficiency. As shown in Figures 21 to 24, after the bottle portion 49 is connected, the rear surface of the sealing member 53 abuts the front surface of the bottle mouth flange 57, the inner edge of the sealing member 52 abuts the outer surface of the bottle mouth ring wall 56, and the bottle mouth end wall 58 is sandwiched between the abutment protrusion 64 and the retaining protrusion 68, securing the conveyor member 52 relative to the bottle body 51 along the first direction Z. The two abutment protrusions 67 in the same set are abutted by the corresponding stop protrusions 59 along the first rotational direction ω, allowing the bottle body 51 to rotate the conveyor member 52 along the first rotational direction ω. When the stop protrusion 59 abuts the abutment protrusion 67, the two spiral protrusions 69 are respectively positioned to correspond to the two spiral protrusions 60. Specifically, the front surface of the spiral projection 69 engages with the front end of the corresponding spiral groove 61, so that when the bottle portion rotates in the first rotational direction ω, toner moving in the first direction Z through the spiral groove 61 is smoothly transferred to the front surface of the spiral projection 69. There, the toner is propelled by the spiral projection 69 to continue moving in the first direction Z until it falls from the front end of the spiral projection 69 onto the corresponding first stopper 65. Thus, by rotating the bottle portion 49 in the first rotational direction ω, the toner is moved from the toner-containing bottle body 51 in the first direction Z to the first stopper 65. In particular, when there is little toner in the bottle body 51, the toner will primarily concentrate in the spiral groove 61. At this point, the toner moves in the first rotational direction ω to the front surface of the spiral projection 69, then escapes from the front end of the spiral projection 69 and falls onto the first stopper 65.

[0090] Referring to Figures 25 to 30, Figures 25 to 30 illustrate the cover 50 and integrated circuit board 4 in this embodiment. As shown in Figure 25, the cover 50 includes a cover body 70, an elastic sealing member 71, and a sliding cover 72. As shown in Figures 26 and 27, the cover body 70 is provided with a partition wall 73, a front wall 74, and a rear wall 75 that are integrally connected to each other. The partition wall 73 is disc-shaped and perpendicular to the second direction Y. The front wall 74 extends from a portion of the outer edge of the partition wall 73 along the first direction Z, and the rear wall 75 extends from the outer edge of the partition wall 73 along the second direction Y. The cover body 70 is provided with an operating unit 76 in front of the partition wall 73. The operating unit 76 is provided with at least two operating parts 77, each of which is suitable for being operated by different fingers of the same hand. In this embodiment, the "operating part" refers to the part of the cover body 70 that directly contacts the fingers. When there are two operating portions 77, the two operating portions 77 face away from each other, suitable for operation by the thumb and index finger, respectively. When there are three operating portions 77, the three operating portions 77 can be arranged in a triangular configuration, suitable for operation by the thumb, index finger, and middle finger, respectively, but at least two operating portions 77 face away from each other. A pulling space 80 is provided between at least one operating portion 77 and the partition wall 73. The pulling space 80 is designed to accommodate the fingertip of a finger, allowing the user to pull the toner bottle 3 in the first direction Z to remove the toner bottle 3 from the body 2. In the operating unit 76, at least one operating portion 77 also drives the second engaging portion 78 to move radially, thereby engaging or disengaging the second engaging portion 78 with the first engaging portion 29. Specifically, when two fingers apply force toward the two operating portions 77, at least one of the operating portions 77 deforms radially inward, driving the corresponding second engaging portion 78 to move radially inward, disengaging the second engaging portion 78 from the first engaging portion 29. When the fingers release the force applied to the two operating portions 77, at least one of the operating portions 77 recovers its deformation radially outward, driving the corresponding second engaging portion 28 to move radially outward, engaging the second engaging portion 78 with the first engaging portion 29. In this embodiment, "radial deformation," "radial outward deformation," and "radial inward deformation" refer to deformation having at least a component perpendicular to the first direction Z; "radial movement," "radial outward movement," and "radial inward movement" refer to movement having at least a component perpendicular to the first direction Z. When the second engaging portion 78 is engaged with the first engaging portion 29, the cover 70 is fixed relative to the housing 5 in both the second direction Y and the first direction Z. When the second engaging portion 28 is disengaged from the first engaging portion 29, the cover 70 is able to move relative to the housing 5 in either the second direction Y or the first direction Z. In a preferred embodiment, when the second matching portion 78 is engaged with the first matching portion 29, the cover 70 is not only fixed relative to the housing 5 along the second direction Y and the first direction Z, but also fixed relative to the housing 5 along the first rotational direction ω, thereby fixing the cover 70 relative to the housing 5.In another preferred embodiment, when the second mating portion 78 is engaged with the first mating portion 29, the cover 70 is only fixed relative to the housing 5 along the second direction Y and the first direction Z. In this case, the cover 70 should also be provided with other structures to engage with the housing 5 to secure the cover 70 and the housing 5 along the first rotational direction ω. In order to cause the deformation of the operating portion 77 to drive the corresponding second mating portion 78 to move radially, the operating unit 76 is further provided with a driving portion 79. The driving portion 79 is used to transmit the radial deformation of the operating portion 77 to the second mating portion 78, causing the second mating portion 78 to move radially. The driving portion 79 may be integrally connected to the operating portion 77 or not. The driving portion 79 may drive the second mating portion 78 to move radially by deformation or without deformation. When a finger applies force toward the two operating portions 77, at least one of the operating portions 77 deforms radially inward, driving the second mating portion 78 radially inward via the corresponding driving portion 79. When the finger releases the force applied to the two operating portions 77, at least one of the operating portions 77 recovers its deformation radially outward, driving the second mating portion 78 radially outward via the corresponding driving portion 29. In a preferred embodiment, the second mating portion 78 is located on the outer edge of the driving portion 79. The driving portion 79 is integrally connected to the corresponding operating portion 77 and deforms in response to the deformation of the corresponding operating portion 77. In a preferred embodiment, the outer edge of the driving portion 79 is configured so that, when the driving portion 79 recovers its deformation, its projection on a plane perpendicular to the second direction Y coincides with the projection of the outer edge of the rear wall 75. In a preferred embodiment, a gap is provided between the driving portion 79 and the partition wall 73 to facilitate deformation of the driving portion 79. In this embodiment, the operating unit 76 includes two operating portions 77, a second mating portion 78, and a driving portion 79. The two operating portions 77 of the operating unit 76 face away from each other and extend along the second direction Y. The two operating portions 77 are adapted to be operated by the thumb and index finger, respectively. Both operating portions 77 are adapted to deform radially inward when a finger exerts force, and a pulling space 80 is provided between each operating portion 77 and the partition wall 73. One of the operating portions 77 is integrally connected to a driving portion 79, which is integrally connected to the front wall 74. The outer edge of the driving portion 79 is configured so that, when the driving portion 79 recovers its deformation, its projection on a plane perpendicular to the first direction Z partially overlaps with the projection of the outer edge of the rear wall 75. At least a portion of the driving portion 79 is spaced apart from the partition wall 73. The second mating portion 78 is configured as a protrusion on the outer edge surface of the driving portion 79. When the fingers apply force to the two operating portions 77 toward each other, at least one of the operating portions 77 deforms radially inward, driving the corresponding driving portion 29 to deform radially inward, causing the second mating portion 78 to move radially inward, and the second mating portion 78 is disengaged from the first mating portion 29, or the toner bottle 3 is able to move along the second direction Y.When the finger releases the force exerted on the two operating portions 77, at least one of the operating portions 77 recovers its deformation radially outward, driving the corresponding driving portion 79 to recover its deformation radially outward, allowing the second engaging portion 78 to extend into and engage with the first engaging portion 29. The cover 50 is then restrained relative to the housing 5 not only in the second direction Y but also in the first rotational direction ω, thereby firmly connecting the cover 50 to the housing 5. Preferably, the rear surface of the second engaging portion 78 is configured to be inclined inwardly in the second direction Y. In this case, as the toner bottle 3 is installed into the body 2 in the second direction Y, the second engaging portion 78 is gradually pressed inward by the housing 5, causing the driving portion 79 to deform inward, similarly moving the toner bottle 3 in the second direction Y until the second engaging portion 78 engages with the first engaging portion 29. In other embodiments, when the first engaging portion 29 is designed to protrude from the wall of the bottle receiving chamber 17, the second engaging portion 78 is correspondingly designed as a hole or groove to facilitate the insertion and engagement of the first engaging portion 29. As shown in Figure 27, in this embodiment, a rearward-facing sealing stop surface 81 is provided on the inner side of the rear wall 75 behind the partition wall 73. The sealing stop surface 81 is annular and is adapted to abut against the front surface of the sealing member 53. Between the plane of the rear surface of the partition wall 73 and the plane of the sealing stop surface 81, the partition wall 73 and the rear wall 75 enclose a powder feeding chamber 82. The powder feeding chamber 82 has a rearward opening. The rear wall 75 also has a powder feeding port 83 that laterally connects to the powder feeding chamber 82. In this embodiment, the powder feeding port 83 extends through the rear wall 75 perpendicular to the second direction Y and is adjacent to the partition wall 73. The rear surface of the partition wall 73 also has a stirring blade 84 extending along the second direction Y. After the toner bottle 3 is connected, the stirring blade 84 is used to assist in stirring the toner fed by the bottle portion 48 along the first rotational direction ω to prevent the toner from clumping. In this embodiment, the rear wall 75 is further provided with four second elastic claws 85 evenly distributed along the circumference. The second elastic claws 85 are positioned entirely behind the sealing stop surface 81. The claw bodies of the second elastic claws 85 extend in the first direction Z, and the claw heads are located at the front end of the claw bodies and have inclined claw surfaces facing inward and backward. The claw heads also have forward-facing abutment surfaces. In this embodiment, the rear end of the rear wall 75 is further provided with a pulling portion 86. The pulling portion 86 protrudes radially outward from the outer edge of the rear wall 75, and its circumferential position corresponds to the circumferential position of the powder feed port 83. In this embodiment, the pulling portion 86 is designed as an elastic claw. The claw body extends in the second direction Y, and the claw heads are located at the rear end of the claw body and have claw surfaces facing outward and forward. The pulling portion 86 is used to push the cover 6 relative to the housing 5 in the first direction Z until the powder feed port 22 is closed when the toner bottle 3 moves relative to the body 2 in the first direction Z. In other embodiments, the pulling portion 86 may also be configured as a protrusion protruding from the outer surface of the rear wall 75 .In this embodiment, a guide portion 87 is further provided on the front wall 74. The guide portion 87 protrudes radially outward from the outer edge of the front wall 74. The guide portion 87 is configured to cooperate with the guide channel 20 to guide the toner bottle 3 during installation and removal from the body 2. In other embodiments, the guide portion 87 may also be provided on the rear wall 75. In other embodiments, the guide portion 87 and the guide channel 20 may be interchangeable, with the guide portion 87 being provided on the housing 5 and the guide channel 20 being provided on the cover 70. In other embodiments, if the engagement of the second engaging portion 78 with the first engaging portion 29 only secures the cover 70 relative to the housing 5 in the second direction Y and the first direction Z, the guide channel 20 may be designed so that when the guide portion 87 abuts the stopper 23, the guide portion 87 and the guide channel 20 engage in a rotationally fixed manner, thereby securing the cover 70 relative to the housing 5 in the first rotational direction ω. As shown in FIG26 , the cover body 70 is further provided with two slide rails 88 . Both slide rails 88 extend from the front wall 74 to the rear wall 75 along the second direction Y. The powder feed port 83 is circumferentially located between the two slide rails 88 . The slide rails 88 are radially projecting from the outer edge surfaces of the front wall 74 and the rear wall 75 and are configured to cooperate with the sliding cover 72 to enable the sliding cover 72 to slide relative to the cover body 70 along the second direction Y and the first direction Z. In this embodiment, a limiting protrusion 89 is further provided on the outer edge surface of the front wall 74 . The limiting protrusion 89 protrudes outward from the front wall 74 to a greater extent than the sliding cover 72 protrudes outward from the front wall 74. The limiting protrusion 89 is located at the front end of the front wall 74 . The limiting protrusion 89 is circumferentially located between the two slide rails 88 and is configured to limit the travel of the sliding cover 72 along the first direction Z. As shown in Figures 26, 28, and 30, the cover 70 also includes a retainer 90 for holding the integrated circuit board 4 and securing it relative to the cover 70. The retainer 90 is located at the front end of the cover 70 and protrudes from the outer edge of the front wall 74. A stopper 91 and a third elastic claw 92 are positioned on the outside of the retainer 90, facing each other. The stopper 91 has a rearward-facing stopper surface. This stopper surface is configured to align vertically with the claw surface of the head of the first elastic claw 36 after the integrated circuit board 4 enters the front portion of the board cavity 37. In this embodiment, the stopper surface is located midway between the two claw surfaces. The third elastic claw 92 has a claw body extending in the second direction Y. Its claw head is located at the rear end of the claw body and has a claw surface facing outward and forward. The integrated circuit board 4 is adapted to be mounted between the stopper surface of the stopper 91 and the claw surface of the third elastic claw 92, thereby retaining it relative to the cover 70 in the second direction Y. As shown in Figure 26 , the cover 70 further includes a push portion 93 located behind the powder feed port 83 and in front of the pull portion 86. The push portion 93 radially protrudes from the outer edge of the rear wall 75 and is used to push the cover 6 relative to the housing 5 in the second direction Y to open the powder feed port 22 when the toner bottle 3 is installed in the body 2 in the second direction Y. In this embodiment, the push portion 93 is designed as the rear end of the slide rail 88.In other embodiments, the push portion 93 may also be provided separately. As shown in Figure 25, the elastic seal 71 is an elastic foam member fixedly attached to the outer edges of the front wall 74 and the rear wall 75. The elastic seal 71 is circumferentially positioned between the two slide rails 88 and behind the stop projection 89 along the first direction Z. The elastic seal 71 is provided with a through hole 94 corresponding to and communicating with the powder feed port 83. As shown in Figures 25, 28, and 29, the sliding cover 72 includes a plate 95 having an arcuate cross-section. The inner surface of the rear end of the plate 95 has an inclined surface that tilts backward in the inward direction. The plate 95 is adapted to engage with the two slide rails 88, allowing the sliding cover 72 to be guided by the two slide rails 88 to slide relative to the cover 70 in the second direction Y to close the through hole 94 or to slide relative to the cover 70 in the first direction Z to open the through hole 94. The outer surface of the plate 95 is provided with a stopper 96 and a blocking member 97. The retaining engagement portion 96 is located forward of the blocking engagement portion 97. The retaining engagement portion 96 is adapted to cooperate with the retaining engagement portion 32, thereby preventing the sliding cover 72 from following the cover body 70 in the first direction Z when the toner bottle 3 is removed from the body 2 in the first direction Z, thereby allowing the sliding cover 72 to slide relative to the cover body 70 in the second direction Y to close the through-hole 94. The blocking engagement portion 97 is adapted to cooperate with the blocking engagement portion 31, thereby preventing the sliding cover 72 from following the cover body 70 in the second direction Y when the toner bottle 3 is inserted into the body 2 in the second direction Y, thereby allowing the sliding cover 72 to slide relative to the cover body 70 in the first direction Z until it abuts against the limiting protrusion 89 to open the through-hole 94.

[0091] Referring to Figures 31 to 33 , they illustrate the toner bottle 3 after it has been connected in this embodiment. The toner bottle 3 is connected by moving the cover 50 relative to the bottle portion 49 in the second direction Y, with the agitator blade 84 facing the bottle opening. During this process, the inwardly and rearwardly facing inclined surface of the second elastic claw 85 abuts the front end of the outer edge of the seal 51, causing the second elastic claw 85 to deform outward until the bottle opening flange 57 of the bottle body 51 passes over the forward-facing abutting surface of the second elastic claw 85 in the first direction Z. This completes the connection of the toner bottle 3. As shown in Figures 31 and 32 , after the toner bottle 3 is connected, the forward-facing abutting surface of the second elastic claw 85 presses against the rear surface of the bottle opening flange 57, causing the seal 53 to elastically abut the sealing stop surface 81 of the cover 70, thereby achieving a sealed connection between the bottle portion 49 and the cover 50 and simultaneously limiting the bottle portion 49 relative to the cover 50 in the second direction Y. Because the bottle portion 49 is secured by four circumferentially distributed second elastic claws 85, it has freedom of movement along the first rotational direction ω and cannot radially disengage from the cover 70. This allows the bottle portion 49 to rotate relative to the cover 50 in the first rotational direction ω. At this point, the stirring member 84 extends from the bottle opening into the bottle mouth portion 54 to stir the toner as the bottle portion 49 rotates. The first and second baffles 65 and 66 extend into the powder feeding chamber 82. As shown in Figures 31 and 33, in this embodiment, after the toner bottle 3 is connected, the outer edges of the first and second baffles 65 and 66 rotatably abut against the sidewalls of the powder feeding chamber 82 (i.e., the inner wall of the rear wall 75). The powder feeding port 83 is located on one side of the vertical plane of the rotational axis of the bottle portion 49 and is tilted downward from the inside out. Similarly, the through hole 94 of the elastic sealing member 71 is also tilted downward from the inside out. Because the powder feed port 83 in this embodiment is arranged laterally, the overall thickness of the developing device 1 can be reduced in the vertical direction. However, due to the lateral arrangement of the powder feed port 83, toner cannot be transported from the bottom of the inner surface of the bottle portion 49 to the powder feed port 83 solely by gravity. Instead, the first baffle 65 is required to lift the toner to the position of the powder feed port 83 and then discharge it from the powder feed port 83. As shown in Figure 33, when the outer edge of the first baffle 65 rotates along the first rotation direction ω to abut the inner lower edge of the powder feed port 83, the first baffle 65 tilts downward from the inside to the outside. This allows toner that has fallen from the front end of the corresponding spiral protrusion 69 onto the first baffle 65 to be transported to the powder feed port 83. In this embodiment, when only a small amount of toner is stored in the bottle portion 49, the detailed process by which the toner is discharged from the bottle body 51 through the through hole 94 in the toner bottle 3 is as follows: the bottle portion 49 rotates relative to the cover portion 50 in a first rotational direction ω, and the toner is conveyed along the first direction Z in the spiral groove 61 of the bottle body 51 to the front end of the bottle body 55. Because the front surface of the spiral protrusion 69 of the conveying member 52 abuts against the spiral groove 61, the toner is transferred from the spiral groove 61 to the front surface of the spiral protrusion 69.Since the conveying member 52 is pushed by the bottle body 51 to rotate along the first rotation direction ω with the bottle body 51, the toner is pushed by the spiral protrusion 69 to move along the first direction Z until it reaches the front end of the spiral protrusion 69. After leaving the front end of the spiral protrusion 69, the toner falls onto the upper surface of the first baffle 65 until the outer edge of the first baffle 65 moves to the inner edge of the powder feeding port 83. Since the upper surface of the first baffle 65 is in a state of tilting downward from the inside to the outside at this time, the toner enters the powder feeding port 83 from the first baffle 65. Since the powder feeding port 83 and the through hole 94 are both configured to tilt downward from the inside to the outside, the toner can be output from the through hole 94.

[0092] Referring to Figures 34 to 43, Figures 34 to 36 illustrate the process of installing the toner bottle 3 and integrated circuit board 4 into the main body 2. Figures 37 to 43 illustrate the connection between the toner bottle 3 and integrated circuit board 4 and the main body 2 when the developing device 1 is in operation. In this embodiment, the process of installing the toner bottle 3 and integrated circuit board 4 into the main body 2 is divided into three steps. In step 1, the toner bottle 3 and integrated circuit board 4 are moved relative to the main body 2 from an initial position along the second direction Y to a first position. As shown in Figure 34, in the initial position, the integrated circuit board 4 is installed between the stop block 91 and the third elastic claw 92 of the retaining frame 90. The toner bottle 3 and integrated circuit board 4 are moved away from the main body 2 along the first direction Z and aligned with the main body 2 with the bottle body 51 extending along the second direction Y, the bottle bottom groove 62 facing the bottle insertion opening 21, and the guide portion 87 aligned with the guide channel 20. The user's fingers push the front ends of the two operating portions 77, thereby moving the toner bottle 3 and the integrated circuit board 4 relative to the body 2 in the second direction Y. The bottle 51 enters the bottle receiving chamber 17 through the bottle insertion opening 21. The guide portion 87, guided by the first channel of the guide channel 20, moves in the second direction Y until it abuts the rear end of the first channel. At this point, the toner bottle 3 and the integrated circuit board 4 are in the first state. In the first state, the retaining engagement portion 96 extends from below the retaining portion 32 in the second direction Y, passing over the rear end of the retaining portion 32. The pulling portion 86 extends from below the cover 6 in the second direction Y, passing over the rear end of the cover 6. In step 2, the toner bottle 3 and the integrated circuit board 4 move relative to the body 2 from the first state to the second state. The user's fingers rotate the two operating portions 77, causing the toner bottle 3 and the integrated circuit board 4 to rotate in the first rotational direction ω. The guide portion 87, guided by the second channel of the guide channel 20, rotates in the first rotational direction ω from the first end of the second channel to the second end of the second channel. At this point, the toner bottle 3 and the integrated circuit board 4 are in the second state. As shown in Figure 35 , when the toner bottle 3 and integrated circuit board 4 are in the second state, the retaining engagement portion 96 rotates in the first rotational direction ω to directly behind the retaining engagement portion 32, and the blocking engagement portion 97 faces the blocking portion 31 in the second direction Y. The pulling portion 86 rotates in the first rotational direction ω to directly behind the cover 6, and the pushing portion 93 faces the cover 6 in the second direction Y, positioning the cover 6 between the pulling portion 86 and the pushing portion 93. The integrated circuit board 4 faces the plate receiving cavity 37 in the second direction Y and is located in front of the plate receiving cavity 37. The third elastic claw 92 faces the blocking portion 34 in the second direction Y. In step three, the toner bottle 3 and integrated circuit board 4 move relative to the main body 2 from the second state to the developing device 1 entering the operating state. The user pushes the front ends of the two operating parts 77 with two fingers, pushing the toner bottle 3 and the integrated circuit board 4 to move relative to the body 2 along the second direction Y. During this process, the two fingers can apply force towards the two operating parts 77 to cause the driving part 79 to deform radially inward. The two fingers can also not apply force towards the two operating parts 77 to cause the driving part to deform radially inward through the cooperation between the rear surface of the second matching part 78 and the shell 5, so that the second matching part 78 can enter the bottle cavity 17.During this process, the guide portion 87 is guided by the third channel of the guide channel 20 and moves along the second direction Y from the front end of the third channel to the stop block 23. At this time, the second matching portion 78 is facing the first matching portion 29, and the driving portion 79 restores its deformation, so that the second matching portion 78 extends into the first matching portion 29, the cover body 70 is fixed to the shell 5, and the developing device 1 enters the working state. When the developing device 1 enters the working state, if the rotation phase of the bottle bottom groove 62 is the same as the rotation phase of the sliding connection 43, the stopper 45 and the sliding connection 43 enter the bottle bottom groove 62, and the bottle portion 49 and the sliding connection 43 are locked; if the rotation phase of the bottle bottom groove 62 is different from the rotation phase of the sliding connection 43, the stopper 45 enters the bottle bottom groove 62, and the rear surface of the bottle body 51 presses against the front surface of the sliding connection 43, causing the sliding connection 43 to slide along the second direction Y, and the energy storage member 44 stores energy until the sliding connection 43 is driven by the second rotating member 42 to rotate along the first rotation direction ω until the phase is the same or close to the phase of the bottle bottom groove 62, the energy storage member 44 releases energy and pushes the sliding connection 43 to slide along the first direction Z until the sliding connection 43 enters the bottle bottom groove 62, and the bottle portion 49 and the sliding connection 43 are locked. At this point, one end of the bottle portion 49 is supported by the cover portion 50 and has the freedom to rotate along the first rotational direction ω, while the other end is supported by the sliding connector 43 and can be driven by the bottle portion drive assembly 40 to rotate along the first rotational direction ω. As shown in Figure 40, in the third step, the pusher 93 pushes the cover 6 to slide relative to the housing 5 in the second direction Y, thereby opening the powder inlet 22. As shown in Figure 41, the blocking portion 31 abuts the blocking mating portion 97, causing the sliding cover 72 to slide relative to the cover body 70 in the first direction Z, thereby opening the through-hole 94 until it abuts the limiting protrusion 89. As the sliding cover 72 opens the through-hole 94, the elastic sealing member 71 radially deforms to a shape that abuts the wall of the bottle holding chamber 17, allowing the powder delivery port 83 to seal and connect with the powder inlet 22 through the through-hole 94. This allows toner to enter the powder holding chamber 18 from the toner bottle 3 without leaking into the interior of the body 2. As shown in Figure 43, the third elastic claw 92 is blocked by the stopper 34. Due to the inclined surfaces therebetween, the third elastic claw 92 elastically deforms and extends into the clearance space 35 as the toner bottle 3 moves in the second direction Y. The third elastic claw 92 avoids the first elastic claw 36. The integrated circuit board 4 is pushed by the stopper 91 in the second direction Y, causing the first elastic claw 36 to deform outward. During this process, the information extraction component 14 contacts the integrated circuit board 4 and also deforms outward. Until the integrated circuit board 4 enters the front of the board cavity 37, the first elastic claw 36 recovers its deformation, with its claw head located directly in front of the integrated circuit board 4. The information extraction component 14 then abuts against the input and output terminals on the integrated circuit board 4, thereby establishing an electrical connection between the other modules and the integrated circuit board 4.If this is not the first time the toner bottle 3 and the integrated circuit board 4 are being installed in the main body 2, then, before the toner bottle 3 and the integrated circuit board 4 are installed again, when the toner bottle 3 was last removed from the main body 2, the to-be-recovered plate 4' was blocked by the first elastic claw 36 and accommodated in the front portion of the plate receiving chamber 37. In the third step, the integrated circuit board 4 pushes against the to-be-recovered plate 4' in the second direction Y, causing the to-be-recovered plate 4' to move from the front portion of the plate receiving chamber 37 to the rear portion of the plate receiving chamber 37, and then fall through the passage at the rear portion of the plate receiving chamber 37 that connects to the recovery chamber 38, into the recovery chamber 38, awaiting recovery.

[0093] The process of removing the toner bottle 3 from the main body 2 also includes three steps. In step one, the user applies force toward the two operating portions 77, causing the operating portions 77 to deform the driving portion 79, disengaging the second engaging portion 78 from the first engaging portion 29. Simultaneously, the user's finger or other part of the finger extends into the pulling space 80, pulling the toner bottle 3 in the first direction Z, thereby moving the toner bottle 3 relative to the main body 2 from the working state in the first direction Z to the second state in the first direction Z. During this process, the guide portion 87 is guided by the third channel of the guide channel 20 to move in the first direction Z to the front end of the third channel. The pulling portion 86 pulls the cover 6 in the first direction Z until the cover 6 closes the powder inlet 22. The stopper portion 32 abuts the stopper engaging portion 96, preventing the sliding cover 72 from moving in the first direction Z, allowing the sliding cover 72 to move in the second direction Y relative to the cover body 70 until the sliding cover 72 closes the through-hole 94. During this process, the inclined surface of the rear inner surface of the plate body 95 cooperates with the inclined surface of the elastic seal 71, gradually compressing the elastic seal 71 inward until the sliding cover 72 closes the through-hole 94. The integrated circuit board 4 is blocked by the claw head of the first elastic claw 36 and cannot move relative to the housing 5 in the first direction Z. Simultaneously, the third elastic claw 92 exits the clearance space 35 in the first direction Z and abuts against the inner surface of the integrated circuit board 4, preventing it from moving in the first direction Z. Consequently, the integrated circuit board 4 is retained in the front portion of the board cavity 37, forming a waiting plate 4'. In the second step, the user applies a rotating force to the two operating components 77, driving the toner bottle 3 away from the first rotational direction ω, thereby moving the toner bottle 3 from the second state to the first state. During this process, the guide portion 87 is guided by the second channel of the guide channel 20 to rotate away from the first rotational direction ω, moving from the second end of the second channel to the first end of the second channel. During this process, the retaining engagement portion 96 rotates away from the first rotational direction ω to the rear and lower portion of the retaining portion 32, and the pulling portion 86 rotates away from the first rotational direction ω to the rear and lower portion of the cover 6. In the third step, the user inserts a finger into the pulling space 80 and pulls the toner bottle 3 along the first direction Z, causing the toner bottle 3 to move relative to the body 2 from the first state along the first direction Z to the initial state. During this process, the retaining engagement portion 96 passes over the retaining portion 32 from below along the first direction Z, and the pulling portion 86 passes over the cover 6 from below along the first direction Z, until the toner bottle 2 is separated from the body 3 and returns to the initial state.

[0094] The printing apparatus in this embodiment uses the developing device 1 in this embodiment.

[0095] In this embodiment, the powder feeding port 83 is located on one side of the plumb plane where the rotation axis of the bottle portion 49 is located, that is, the powder feeding port 83 is arranged laterally, and the toner is no longer fed out from the powder feeding port 83 by gravity, and the powder holding chamber 18 of the main body 2 for holding the toner no longer needs to be placed below the toner bottle 3, thereby reducing the thickness of the developing device 1 in the vertical direction, which is conducive to the miniaturization of the printing equipment.

[0096] In this embodiment, the bottle portion 49 and the photosensitive drum 7 are linked together, eliminating the need for a low-powder sensor, a corresponding controller, and a separate drive mechanism for rotating the bottle portion 49 within the powder chamber 18. This simplifies the structure of the developing device 1, improves reliability, and reduces costs. Furthermore, since the rotation of the photosensitive drum 7 is directly related to the amount of printed media, the linkage between the photosensitive drum 7 and the bottle portion 49 establishes a direct correlation between the need for toner replacement and the amount of printed media. This makes it much easier to remind the user to replace the toner bottle 3, eliminating the need to monitor the remaining toner level within the bottle 3. This further simplifies the structure of the developing device 1, improves reliability, and reduces costs, further enhancing the widespread adoption of laser printers and copiers.

[0097] In this embodiment, the first rotating member 39 is exposed from the housing 5, receiving power from the outside. This makes the first rotating member 39 the only externally driven rotating member in the transmission mechanism 13, thereby reducing structural complexity and saving costs. The stirring member 12 located in the powder chamber 18 is driven by the transmission assembly 41. Therefore, the entire transmission mechanism 13 drives at least the photosensitive drum 7, the bottle portion 49, and the stirring member 12, further reducing structural complexity and saving costs.

[0098] In this embodiment, the bottle driving assembly 40 and the cover body 70 are respectively located at the two ends of the bottle portion 51 along the first direction Z, which significantly improves the influence of vibration caused by the joint rotation of the bottle driving assembly 40 and the bottle portion 51 on the output of toner by the cover body 70, so that the loose sealing caused by vibration when the toner is output from the toner bottle 3 to the main body 2 can be improved.

[0099] In this embodiment, the sliding connector 43 can slide relative to the second rotatable member 42, eliminating the need to establish a rotationally locked engagement with the bottle drive assembly 40 when the toner bottle 3 is fully inserted into the body 2. This is because, if the toner bottle 3 were to establish a rotationally locked engagement with the bottle drive assembly 40 upon full insertion, the rear end of the bottle body 51 would require a sophisticated, sloped guide structure to ensure that the bottle portion 49 maintains a rotationally locked engagement with the bottle drive assembly 40 regardless of its rotational phase relative to the body 2. However, in this embodiment, if the rotational phase of the bottle portion 49 differs from that of the sliding connector 43 after the toner bottle 3 is fully inserted, the rear surface of the bottle body 51 will press against the sliding connector 43, causing it to move in the second direction Y, causing the energy storage member 44 to store energy. This energy storage member 44 then releases energy, driving the sliding connector 43 to move in the first direction Z and insert into the bottle bottom groove 62, where it engages with the rotationally locked engagement. Therefore, this embodiment can make the structure of the bottle body 51 simpler, easier to process, and suitable for manufacturing by blow molding process. In this embodiment, the energy storage member 44 adopts a spring, which is lower in cost and simpler in structure.

[0100] In this embodiment, the powder feeding chamber 82 is laterally connected to the powder feeding port 83, and the outer edge of the first baffle 65 abuts against the side wall of the powder feeding chamber 82. This not only agitates the toner but also facilitates lifting the toner to the powder feeding port 83. When the outer edge of the first baffle 65 rotates to abut the lower edge of the powder feeding port 83, the first baffle 65 tilts downward from the inside to the outside, facilitating the gravity transfer of the lifted toner to the powder feeding port 83. The powder feeding port 83 also tilts downward from the inside to the outside, facilitating the outward transport of toner from the powder feeding port 83.

[0101] In this embodiment, the bottle body 51 and the conveying member 52 are manufactured separately, so that the bottle body 51 can be manufactured by blow molding, which is beneficial to reducing structural complexity and manufacturing difficulty.

[0102] In this embodiment, the bottle body 51 and the conveying member 52 are secured along the first direction Z by intervening engagement between the bottle end wall 58, the abutting flange 64, and the latching protrusion 68. This facilitates the connection between the conveying member 52 and the bottle body 51. Specifically, when the conveying member 52 is inserted into the bottle body 51 along the second direction Y, the latching protrusion 68 deforms and moves inward until the latching protrusion 68 passes over the bottle end wall 58, latching the bottle body 51 and the conveying member 52 together. This facilitates the connection between the conveying member 52 and the bottle body 51, thereby improving assembly efficiency.

[0103] In this embodiment, the front surface of the spiral protrusion 69 of the conveying member 52 engages with the spiral groove 61, allowing the toner moving in the first direction Z to continue to move on the conveying member 52, pushed by the spiral protrusion 69, in the first direction Z. The front end of the spiral protrusion 69 faces away from the first rotational direction ω and toward the first baffle 65, allowing the first baffle 65 to receive toner that falls from the front end of the spiral protrusion 69. This facilitates the efficient transfer of residual toner from the bottle 51 to the first baffle 65 when the amount of toner in the bottle 51 is low, and the toner is then transported to the powder feeding port 83 via the first baffle 65, thereby avoiding waste.

[0104] In this embodiment, the bottle body 51 is provided with a stop protrusion 59 configured to abut against the abutment protrusion 67 in the first rotational direction ω, thereby causing the bottle body 51 to drive the conveyor member 52 to rotate in the first rotational direction ω. This facilitates the conveyor member 52 to rotate along the first rotational direction ω when inserted into the bottle body in a direction away from the second rotational direction Y. This eliminates the need to align the conveyor member 52 in the first rotational direction ω; it can simply be rotated after insertion to achieve rotation along the first rotational direction ω with the bottle body 51. The abutment protrusions 67 are divided into two groups, forming a phase angle between the two groups. This helps reduce the rotation angle during assembly of the bottle body 51 and the conveyor member 52, thereby improving production efficiency.

[0105] In this embodiment, the front surface of the second elastic claw 85 abuts forward against the rear surface of the bottle mouth flange 57, causing the seal 53 to elastically abut forward against the sealing stop surface 81, thereby limiting the position of the bottle portion 49 relative to the cover body 70 in the first direction Z. As is well known, while elastic claw engagement facilitates assembly, a gap often exists after engagement. In this patent, a seal 53 elastic in the first direction Z is provided between the claw head of the second elastic claw 85 and the sealing stop surface 81. This not only achieves axial positional limitation but also ensures sealed communication between the bottle portion 49 and the powder feeding chamber 82. The at least two circumferentially distributed second elastic claws 85 not only restrict the bottle portion 49 from radially disengaging from the cover body 70 but also provide the bottle portion 49 with the freedom to rotate relative to the cover body 70 in the first rotational direction ω. Consequently, assembly is facilitated and a good sealing effect is achieved after the rotational connection is established.

[0106] In this embodiment, the powder feeding port 83 is adjacent to the partition wall 73 , so that toner does not remain at the front end of the powder feeding chamber 82 .

[0107] In this embodiment, the rear surface of the claw head of the second elastic claw 85 is inclined inwardly along the first direction Z. This allows the claw head to automatically deform radially outwardly due to the engagement with the inclined surface of the bottle portion 49 when the bottle portion 49 moves toward the cover body 70 along the first direction Z. This allows the sealing member 53 and the bottle mouth flange 57 of the bottle portion 49 to enter between the sealing stop surface 81 and the front surface of the second elastic claw 85. The second elastic claw 85 then recovers its deformation and abuts against the rear surface of the bottle mouth flange 57, thereby achieving rapid assembly and improving assembly efficiency.

[0108] In this embodiment, the operating unit 76 has at least two operating portions 77 suitable for direct contact by different fingers of the same hand. At least two operating portions 77 face away from each other to facilitate operation by the thumb and any other finger. This allows different fingers of the same hand to operate each operating portion 77. This allows the operating unit 76 to be positioned within a relatively small operating space, enabling the insertion and removal of the toner bottle 3. Because the cover 70 is positioned at the front end of the toner bottle 3 along the first direction Z and the operating unit 76 is positioned at the front end of the cover, the toner bottle 3 can be manipulated from the end thereof by finger operation, thereby enabling insertion of the toner bottle 3 into the housing 5 along its extending direction. This reduces the opening of the housing 5, making it difficult for objects to enter the housing 5 and cause malfunction of the housing 2. A pulling space 80 is formed behind at least one operating portion 77, suitable for insertion of the fingertip of the corresponding finger. This facilitates the fingertip's insertion into the pulling space 80 to forcefully remove the toner bottle 3 from the housing 5 along its first direction Z. In this embodiment, by applying force toward the two operating portions 77, which are facing away from each other, the second engaging portion 78 can be driven to move radially relative to the cover 70, enabling the second engaging portion 78 to engage or disengage with the first engaging portion 29, thereby enabling the toner bottle 3 to be smoothly inserted into the body 2 along the second direction Y or removed from the body 2 along the first direction Z. In this embodiment, the driving portion 79 is integrally connected to the operating portion 77. Radial deformation of the operating portion 77 can also cause the driving portion 79 to deform radially. The second engaging portion 78 is disposed on the outer edge of the driving portion 79, facilitating engagement and disengagement with the first engaging portion. The driving portion 79 is at least partially spaced from the partition wall 73, facilitating deformation of the driving portion. The outer edge of the driving portion 79 partially overlaps with the outer edge of the rear wall 75 when recovering from deformation, facilitating engagement and disengagement of the second engaging portion 78 with the first engaging portion 22 with minimal movement, thus minimizing the need for finger force on the operating portion 77. The second engaging portion 78 is configured as a projection with its rear surface inclined outwardly along the first direction. When the toner bottle 3 is installed into the body 2 along the second direction Y, there is no need to apply force toward the two operating portions 77 facing away from each other. The second engaging portion 78 only needs to engage with the inclined surface of the wall of the bottle receiving cavity 17 to force the driving portion 79 to deform and cause the second engaging portion 78 to enter the bottle receiving cavity 17.

[0109] In this embodiment, the guide channel 20 cooperates with the guide portion 87 to provide guidance for the process of installing the toner bottle 3 into the body 2, making it easier for the user to replace the toner bottle.

[0110] In this embodiment, the elastic sealing member 71 presses against the wall of the bottle containing cavity 17 when the sliding cover 72 opens the powder feeding port 83 , thereby better sealing the powder feeding port 83 and the powder inlet 22 to avoid powder leakage.

[0111] In this embodiment, the inner surface of the rear end of the sliding cover 72 is inclined, which can gradually compress the elastic seal 71 when it abuts the elastic seal 71, thereby preventing the elastic seal 71 from being damaged due to the pressure of the sliding cover 72 and extending the life of the toner bottle 3.

[0112] In this embodiment, by providing a blocking fitting portion 97 and a stop fitting portion 96 protruding from the outer surface of the plate body 95 , the interval between the blocking portion 31 and the stop portion 32 can be reduced, which is beneficial for further reducing the length of the developing device 1 along the first direction Z.

[0113] In this embodiment, since the direction in which the toner bottle 3 is inserted into the body 2 is consistent with the direction of its rotation axis, the opening of the body 2 is relatively small, and foreign matter is not likely to enter the body and cause a malfunction of the body 2 .

[0114] In this embodiment, when the toner bottle 3 is loaded into the body 2, the blocking portion 31 abuts the blocking engagement portion 97, causing the sliding cover 72 to open the through-hole 94, and the pushing portion 93 abuts the cover 6 to open the powder inlet 22, thereby preventing powder leakage during loading. When the toner bottle 3 is removed from the body 2, the retaining portion 32 abuts the retaining engagement portion 96, causing the sliding cover 72 to close the through-hole 94, and the pulling portion 86 abuts the cover 6 to close the powder inlet 22, thereby preventing powder leakage during removal.

[0115] In this embodiment, during the process of installing the toner bottle 3 into the main body 2, the stop-recession fitting portion 96 passes over the stop-recession portion 32 from below the stop-recession portion 32 along the second direction Y or the first direction Z, and the pulling portion 86 passes over the cover 6 from below the cover 6 along the second direction Y or the first direction Z. This can prevent the uncertainty of movement caused by the interference between the stop-recession portion 32 and the stop-recession fitting portion 96 and the interference between the pulling portion 86 and the cover 6, increase the certainty of the action and its effect, and make it more convenient for users to use.

[0116] This embodiment can realize the recycling of the integrated circuit board 4, which not only avoids waste, but also helps to determine whether an unauthorized toner bottle 3 is used to replenish toner by analyzing the model and stored information of the integrated circuit board 4, and based on this, determine a specific plan for repairing the printing device.

[0117] In this embodiment, the limiting block 91 and the third elastic claw 92 are provided to retain the integrated circuit board 4 on the toner bottle 3 when the toner bottle 3 is not installed in the main body 2, which facilitates achieving correspondence between the information of the integrated circuit board 4 and the toner bottle 3. The stopper 34 is provided to elastically deform the third elastic claw 92, so that the integrated circuit board 4 can smoothly enter the front of the board receiving chamber 37. The third elastic claw 92 is provided to prevent the integrated circuit board 4 from exiting, so that the integrated circuit board 4 is retained in the board receiving chamber 37. By providing vertical communication between the rear portion of the board receiving chamber 37 and the recovery chamber 38, the board to be recovered 4' can enter the recovery chamber 38 and wait for recovery. The new integrated circuit board 4 is pressed against the board to be recovered 4', allowing the board to be recovered 4' to move through the rear portion of the board receiving chamber 37 into the recovery chamber 38.

[0118] In this embodiment, the integrated circuit board 4 is automatically recycled during the process of installing the toner bottle 3 into the body 2, without causing any trouble to the user.

[0119] Example 2

[0120] The difference between the second embodiment and the first embodiment is that the housing 5 in the second embodiment is different from the housing 5 in the first embodiment, the cover 50 in the second embodiment is different from the cover 50 in the first embodiment, and the method of installing the toner bottle 3 and the integrated circuit board 4 into the body 2 in the second embodiment is different from the method of installing the toner bottle 3 into the body 2 in the first embodiment. The details are as follows:

[0121] Referring to Figure 44 , Figure 44 illustrates the housing 5 in this embodiment. As shown in Figure 44 , in this embodiment, the guide channel 20 extends only along the second direction Y. In this embodiment, both the upper housing 15 and the lower housing 16 are provided with a first mating portion 29, both of which are holes. In this embodiment, the blocking portion 31 is no longer provided with a stopper 32 in front of the blocking portion 31. Instead, a fourth elastic claw 98 is provided at the front end of the lower housing body 25. The claw body of the fourth elastic claw 98 extends along the first direction Z, with its claw head facing inward and rearward, and the front surface of its claw head tilted inward along the second direction Y. The fourth elastic claw 98 is configured to cooperate with the stopper mating portion 96. In this embodiment, the housing 5 is further provided with a first blocking block at the front end of the guide rail 30. The first blocking block is used to prevent the cover 6 from continuing to move in the first direction Z after closing the powder inlet 22.

[0122] Referring to Figures 45 and 46 , the cover 50 according to the second embodiment is shown. As shown in Figures 45 and 46 , in this embodiment, the operating unit 76 of the cover 70 comprises two operating portions 77 integrally connected to the corresponding driving portion 79. Each driving portion 79 is provided with a second engaging portion 78, which radially protrudes from the outer edge of the driving portion 29. The two second engaging portions 78 face away from each other and are adapted to engage with the corresponding first engaging portion 29. In this embodiment, a fifth elastic claw 99 is provided behind the push portion 93. The claw body of the fifth elastic claw 99 extends in the second direction Y, with the claw head facing forward and outward, and the rear surface of the claw head tilted inward along the second direction Y. In this embodiment, the plate 95 of the sliding cover 72 serves as the blocking engaging portion 97. The front surface of the retaining engaging portion 96 on the plate 95 is tilted outward along the second direction Y, while the rear surface thereof is tilted inward along the second direction Y. In this embodiment, the cover body 70 is further provided with a second blocking block at the rear end of the slide rail 88 , and the second blocking block is used to prevent the sliding cover 72 from continuing to move along the second direction Y relative to the cover body 70 after closing the through hole 94 .

[0123] Referring to Figures 47 to 51, Figures 47 to 51 illustrate the structure of the developing device 1 in this embodiment in its operating state. As shown in Figure 47, in this embodiment, the process of installing the toner bottle 3 and integrated circuit board 4 into the body 2 consists of a single step: driving the toner bottle 3 and integrated circuit board 4 from their initial state along the second direction Y until the guide portion 87 moves from the front end of the guide channel 20 to the rear end of the guide channel 20, thereby placing the developing device 1 in its operating state. During this process, the two operating portions 77 can be deformed toward each other by a finger, thereby causing the two second mating portions 78 to move radially inward, driven by their corresponding driving portions 79. Alternatively, the finger can be free of force applied to the two operating portions 77, allowing the second mating portions 78 to abut against the inclined surface of the housing 5, causing the driving portion 79 to deform radially inward, thereby allowing the second mating portions 78 to enter the bottle cavity 17. As shown in Figures 48 to 50 , during this process, when the fifth elastic claw 99 abuts the cover 6, its rear surface is tilted inwardly along the second direction Y. Therefore, the fifth elastic claw 99 deforms inwardly and passes over the cover 6 until its claw head is located behind the cover 6, at which point the fifth elastic claw 99 recovers its deformation. As shown in Figure 51 , during this process, because the rear surface of the retaining engagement portion 96 is tilted inwardly along the second direction Y, and the front surface of the claw head of the fourth elastic claw 98 is tilted inwardly along the second direction Y, when the retaining engagement portion 96 abuts the fourth elastic claw 98, the fourth elastic claw 98 deforms outwardly until the retaining engagement portion 96 passes over the claw head of the fourth elastic claw 98, at which point the fourth elastic claw 98 recovers its deformation. During this process, the blocking portion 31 abuts the blocking engagement portion 97 forward, preventing the sliding cover 72 from moving in the second direction Y. The sliding cover 72 then moves relative to the cover body 70 in the first direction Z until the through-hole 94 is opened and abuts the stopper protrusion 89.

[0124] In this embodiment, the process of removing the toner bottle 3 from the main body 2 also consists of a single step. During this step, two fingers apply force toward the two operating portions 77 of the toner bottle 3, which are in the operating state, causing the operating portions 77 to deform and move closer together. This, in turn, causes the two mating portions 78 to move radially inward, driven by the corresponding driving portions 79, disengaging the second mating portion 78 from the first mating portion 29. Simultaneously, the two fingers partially extend into the pulling space 80, pulling the toner bottle 3 from the intermediate state in the first direction Z. The guide portion 87 moves from the rear end of the guide channel 20 to the front end of the guide channel 20 until it disengages the guide channel, returning the toner bottle 3 to its initial state relative to the main body 2. During this process, the fifth elastic claw 99 pulls the cover 6 to slide along the first direction Z until it closes the powder inlet 22 and abuts the first blocking block. Because the forward and outward-facing surface of the fifth elastic claw 99 is inclined outward in the second direction Y, after the cover 6 is blocked by the first block, the fifth elastic claw 99 is forced to deform inward, allowing its claw head to pass over the rear end of the cover 6 and abut the surface of the cover 6 until it is free of the cover 6, at which point the fifth elastic claw 99 resumes its deformation. During this process, the fourth elastic claw 98 blocks the retaining portion 96, preventing the sliding cover 72 from sliding in the first direction Z. The sliding cover 72 then slides relative to the cover body 70 in the second direction Y until it closes the through-hole 94 and abuts the second block. Because the front surface of the retaining portion 96 is inclined outward in the second direction Y, after the sliding cover 72 is blocked by the second block, the fourth elastic claw 98 is forced to deform outward, allowing the retaining portion 96 to pass over the claw head of the fourth elastic claw 98 in the first direction Z, at which point the fourth elastic claw 98 resumes its deformation.

[0125] The printing apparatus in this embodiment uses the developing device 1 in this embodiment.

[0126] In this embodiment, a first blocking block is provided so that the fifth elastic claw 99 cooperating with the cover 6 can pass over the cover 6 after the cover 6 closes the powder inlet 22; a second blocking block is provided so that the fourth elastic claw 98 cooperating with the sliding cover 72 can pass over the fourth elastic claw 98 after the sliding cover 72 closes the powder feeding port 83.

[0127] In this embodiment, the steps of installing the toner bottle 3 and integrated circuit board 4 into the body 2 and removing the toner bottle 3 from the body 2 in the developing device 1 are both performed in a single step and are performed along the second direction Y or the first direction Z. This facilitates assembly and disassembly, reducing user learning costs. Furthermore, during this process, neither the toner bottle 3 nor the housing 5 leaks toner.

[0128] The above description of the specification and embodiments is used to explain the scope of protection of the present application, but does not constitute a limitation on the scope of protection of the present application.
