[0003] The purpose of this application is to overcome the aforementioned defects or problems in the prior art and to provide a body, toner bottle, developing apparatus, printing equipment, and method for recycling integrated circuit boards, which can facilitate the recycling of integrated circuit boards.

[0004] To achieve the above objectives, the following technical solution is adopted:

[0005] The first technical solution relates to a body for receiving toner supplied by a toner bottle and outputting a pattern formed by the toner to a printing medium; characterized in that it is also used to accommodate an integrated circuit board loaded along a second direction with the toner bottle and to extract information related to the toner bottle stored on the integrated circuit board; the body includes a housing and an information extraction component, the housing having a board holder, a bottle cavity, and a recycling cavity; the board holder is used to accommodate the integrated circuit board, the bottle cavity is used to accommodate the toner bottle, and the recycling cavity is used to recycle the integrated circuit board; the board holder is adjacent to the bottle cavity and has a stop, a clearance space, a first elastic claw, and a board. The cavity; the stop portion extends along a first direction away from the second direction, and the stop portion forms the clearance space adjacent to the inner side of the container cavity; the first elastic claw is located on the outer side of the stop portion, its claw body extends along the first direction, and its claw head is arranged inward and rearward; a container cavity suitable for accommodating two integrated circuit boards arranged along the first direction is formed between the stop portion and the first elastic claw; the container frame is provided with a support wall at the front of the container cavity to support the integrated circuit boards; the rear of the container cavity communicates downward with the recycling cavity; the information extraction member is adapted to extract the information recorded on the integrated circuit board located at the front of the container cavity.

[0006] The second technical solution is based on the first technical solution, wherein the information extraction component is an electrical connection terminal, the electrical connection terminal extends into the front part of the cavity and is elastic, it is adapted to elastically deform during the process of the integrated circuit board entering the front part of the cavity to avoid the integrated circuit board, and is electrically connected to the integrated circuit board when the integrated circuit board enters the front part of the cavity.

[0007] The third technical solution is based on the first technical solution, wherein the housing includes an upper housing and a lower housing connected to each other, the lower housing includes a lower housing body and a front cover connected to each other, the receiving plate frame is formed in the lower housing body, the recycling cavity is formed between the lower housing body and the front cover, and the front cover is at least partially detachably connected to the lower housing body.

[0008] The fourth technical solution is based on the first technical solution, wherein the housing is further provided with a toner-containing cavity, the toner-containing cavity is used to contain toner and is adjacent to the bottle cavity, and the recycling cavity is located in front of the toner-containing cavity and is isolated from the toner-containing cavity.

[0009] The fifth technical solution relates to a toner bottle for supplying toner to a body as described in any one of the first to fourth technical solutions, and also for carrying the integrated circuit board. The toner bottle extends along a first direction and is adapted to be inserted into the body along a second direction and removed from the body along the first direction. A retainer is provided on the outer side of the toner bottle. The retainer has a limiting block and a third elastic claw. The limiting block has a limiting surface adapted to abut rearward against the integrated circuit board. The limiting surface is configured such that after the integrated circuit board enters the front portion of the cavity, it contacts the claw head of the first elastic claw. The claw surfaces are arranged vertically; the third elastic claw is located behind the limiting block, with its claw head facing outward and forward, forming a gap with the limiting surface suitable for accommodating the integrated circuit board; the third elastic claw is adapted to avoid the first elastic claw during the process of the toner bottle being inserted into the body, so that the first elastic claw elastically deforms outward due to the inclined surface abutting against the integrated circuit board to allow the integrated circuit board to pass through; the third elastic claw is also adapted to abut against the inclined surface of the stop portion and elastically deform inward into the clearance space during the process of the toner bottle being inserted into the body.

[0010] The sixth technical solution is based on the fifth technical solution, wherein the toner bottle includes a cap and a bottle connected to each other, the cap is located further forward and is used to output toner, and the bottle is located further back and is used to contain toner; the cap includes a cap body, and the retainer is formed in the cap body.

[0011] The seventh technical solution relates to a developing apparatus, which includes an integrated circuit board, a body as described in any one of the first to fourth technical solutions, and a toner bottle as described in the fifth or sixth technical solution. The integrated circuit board is adapted to be carried and connected to the body by the toner bottle. When the developing apparatus is in operation, the integrated circuit board is located at the front of the container cavity.

[0012] The eighth technical solution relates to a printing device that includes a developing device as described in the seventh technical solution.

[0013] The ninth technical solution relates to a method for recycling an integrated circuit board, wherein the integrated circuit board is used to store information related to a toner bottle, the toner bottle is used to supply toner to the body of a developing apparatus and to carry the integrated circuit board, wherein, when the toner bottle is inserted into the body, the integrated circuit board is transferred to the body; when the toner bottle is removed from the body, the integrated circuit board is left in the body to form a recycling plate; when a new toner bottle is inserted into the body, during the process of transferring the integrated circuit board corresponding to the new toner bottle to the body, the recycling plate is pushed to a recycling chamber within the body for recycling.

[0014] The tenth technical solution is based on the ninth technical solution and is used in the developing apparatus as described in the seventh technical solution. When the toner bottle is inserted into the body, the third elastic claw deforms inward through its engagement with the inclined surface of the stop portion, entering the clearance space. The first elastic claw deforms outward through its engagement with the inclined surface of the outer surface of the integrated circuit board to avoid the integrated circuit board until it enters the front part of the cavity and then returns to its original shape. When the toner bottle is removed from the body, the first elastic claw prevents the integrated circuit board from exiting the cavity along a first direction. The third elastic claw exits from the clearance space along the first direction until it abuts against and passes over the inner surface of the integrated circuit board. The integrated circuit board left in the front part of the cavity forms a recyclable plate. When a new toner bottle is inserted into the body, the integrated circuit board abuts against the recyclable plate along the first direction, causing the recyclable plate to move along the first direction to the rear part of the cavity and fall from the rear part of the cavity into the recycling chamber for recycling.

[0015] Compared with existing technologies, the above solution has the following beneficial effects:

[0016] The first to tenth technical solutions provide methods for recycling the integrated circuit board body, toner bottle, developing device, printing equipment, and the integrated circuit board itself. These technical solutions enable the recycling of integrated circuit boards, which not only avoids waste but also facilitates the determination of whether unauthorized toner bottles were used to replenish toner by analyzing the model number and stored information of the integrated circuit board, and based on this, determines the specific solution for repairing the printing equipment.

[0017] In the above technical solution, by setting a limiting block and a third elastic claw, the integrated circuit board is held on the toner bottle when the toner bottle is not inserted into the main body, which is beneficial to achieving the correspondence between the integrated circuit board and the toner bottle information. By setting a stop part, the third elastic claw elastically deforms, allowing the integrated circuit board to smoothly enter the front of the container cavity. By setting the third elastic claw to prevent the integrated circuit board from exiting, the integrated circuit board is kept in the container cavity. By setting the rear of the container cavity and a recycling cavity that communicates with the rear of the container cavity in the vertical direction, the board to be recycled can enter the recycling cavity to wait for recycling. By a new integrated circuit board pressing against the board to be recycled, the board to be recycled can move through the rear of the container cavity into the recycling cavity.

[0018] In the above technical solution, the process of loading the toner bottle into the main body automatically realizes the recycling of the integrated circuit board, without causing trouble for the user. Attached Figure Description

[0090] The technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings.

[0091] Example 1

[0092] The developing unit 1 is used to receive selective light signals and selectively apply toner to the image expressed by the selective light signals through a photosensitive drum and transfer it onto the printing medium. Generally, the developing unit 1 is mainly used in printing equipment, such as laser printers or copiers, as long as they have the function of generating an image formed by toner on the printing medium.

[0093] See Figure 1 , Figure 1 The developing apparatus 1 in this embodiment is shown, such as Figure 1As shown, the developing apparatus 1 includes a body 2, a toner bottle 3, and an integrated circuit board 4. The body 2 performs the functions of the developing apparatus 1 and houses the toner bottle 3 and the integrated circuit board 4. The toner bottle 3 supplies toner to the body 2. In this embodiment, the toner bottle 3 is replaceable; that is, the toner bottle 3 can be easily inserted into the body 2 and easily removed from the body 2. Specifically, the toner bottle 3 has at least a step of moving along the second direction Y during insertion into the body 2, and at least a step of moving along the first direction Z during removal from the body 2. The integrated circuit board 4 provides the body 2 with information related to the toner bottle 3, which may include anti-counterfeiting information and / or toner capacity information. The integrated circuit board 4 is detachably fixed to the toner bottle 3 when it is not inserted into the body 2. The integrated circuit board 4 moves with the toner bottle 3 during insertion into the body 2 and is eventually connected to the body 2. The integrated circuit board 4 is retained on the body 2 during removal of the toner bottle 3, forming a recycling plate 4'. When replacing the toner bottle 3, the new integrated circuit board 4 pushes against the recycling plate 4' during the insertion of the toner bottle 3 into the body 2, causing it to move and be housed inside the body 2, thereby achieving the purpose of recyclability or determining whether an unauthorized toner bottle 3 has been used. The structure and shape of the integrated circuit board 4 in the developing apparatus 1 are well known to those skilled in the art and do not involve any improvements related to this patent, therefore they will not be described in detail below.

[0094] See Figure 2 and Figure 3 , Figure 2 and Figure 3 The body 2 in this embodiment is shown. (As shown...) Figure 2 and Figure 3 As shown, the main body 2 includes a housing 5, a cover 6, a photosensitive drum 7, a cleaning component 8, a charging module 9, a developing roller 10, an intermediate roller 11, a stirring component 12, a driving mechanism 13, and an information extraction component 14 (made of...). Figure 43(Shown). The housing 5 houses and supports other components of the main body 2. The structure, connection relationships, 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 selective light signals input from the light-transmitting 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 printing medium. In this embodiment, the photosensitive drum 7 is exposed below the housing 5 to contact the printing medium and transfer the image. In this embodiment, "exposed" means that an object is at least partially not covered by the housing 5, can be directly observed by the naked eye, and can contact or cooperate with components outside the developing device 1. The cleaning member 8 is used to clean 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 based on 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 component 12 is used to stir and transport the toner contained in the housing 5. The drive mechanism 13 is mounted on 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 component 14 is used to extract information from the integrated circuit board 4 so that other modules installed inside the housing 5 can extract and utilize the information recorded on the integrated circuit board 4. In this embodiment, the information extraction component 14 adopts a flexible electrical connection terminal. In other embodiments, the information extraction component can also adopt a non-contact information extraction method, such as NFC. In the body 2, the structure and principle of the photosensitive drum 7, the cleaning component 8, the charging module 9, the developing roller 10, the intermediate roller 11, the stirring component 12, and the information extraction component 14 are well known to those skilled in the art and do not involve improvements related to this patent. Therefore, they will not be described in detail below.

[0095] See Figures 4 to 9 and Figure 43 , Figures 4 to 9 The housing 5 and cover 6 in this embodiment are shown. Figure 43 The information extraction component 14 in this embodiment is shown. For example... Figure 4 and Figure 5 As shown, the housing 5 includes an upper housing 15 and a lower housing 16. The upper housing 15 and the lower housing 16 are detachably fixed together and form a bottle-containing cavity 17, a powder-containing cavity 18, a functional cavity 19, and a guide channel 20. Figure 4As shown, the bottle-containing cavity 17 extends along the second direction Y and is used to house the toner bottle 3. The front end of the bottle-containing cavity 17 has an insertion port 21, which allows the toner bottle 3 to be inserted into the bottle-containing cavity 17 along the second direction Y. In this embodiment, "front" refers to being located in front along the first direction Z, and "rear" refers to being located behind along the first direction Z. The toner-containing cavity 18 is used to house toner, the stirring element 12, and other components. The toner-containing cavity 18 is connected to the bottle-containing cavity 17 through a toner inlet 22. The toner inlet 22 is used to introduce toner from the toner bottle 3 into the toner-containing cavity 18. The functional cavity 19 is adjacent to the toner-containing cavity 18 and is used to house components such as the photosensitive drum 7 and the developing roller 10. Figure 5 As shown, the guide channel 20 is located at the front end of the housing 5 and communicates with the bottle cavity 17. The guide channel 20 is used to guide the toner bottle 3 during the process of inserting the toner bottle 3 into the body 2 and during the process of removing the toner bottle 3 from the body 2. In this embodiment, the guide channel 20 has a Z-shaped structure, which is composed of a first channel, a second channel, and a third channel connected in sequence. The first channel is located at the front of the guide channel 20 and extends along the second direction Y, with an opening at its front end and a connection at its rear end with the second channel. The second channel is located in the middle of the guide channel 20 and extends perpendicular to the second direction Y, with its first end connected to the first channel and its second end connected to the third channel. Figure 4 and Figure 5 As shown, the third channel is located at the rear of the guide channel 20 and extends along the second direction Y. Its front end connects with the second channel, and its rear end extends into the interior of the housing 5 and stops at the stop block 23. Figure 4As shown, the upper housing 15 is provided with a light-transmitting port 24. The light-transmitting port 24 extends along the second direction Y and is used to allow selective light to pass through and irradiate 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 substrate 28 fixed to each other. The lower housing body 25 is provided with a first mating part 29, a guide rail 30, a blocking part 31, a backstop part 32, and a container frame 33. The first mating part 29 is located in the bottle cavity 17 and is used to mate with the toner bottle 3, so that the toner bottle 3 is fixed relative to the housing 5 along the second direction Y and the first direction Z. In this embodiment, the first mating part 29 is designed as a hole. In other embodiments, the first mating part 29 may also be set as a groove or protrude inward from the cavity wall of the bottle cavity 17. In this embodiment, "inner" refers to the direction toward the rotation axis of the bottle part 49 in the toner bottle 3, and "outer" refers to the direction away from the rotation axis of the bottle part 49. There are two guide rails 30, and both guide rails 30 extend along the second direction Y. Along the circumferential direction, the powder inlet 22 is located between two guide rails 30. The two guide rails 30 are used to engage with the cover 6, allowing the cover 6 to slide relative to the housing 5 along the second direction Y and the first direction Z. A blocking part 31 is located in front of the powder inlet 22 and has a forward-facing blocking surface. A retaining part 32 is located in front of the blocking part 31 and has a rearward-facing retaining surface. A container holder 33 is located at the front end of one side of the bottle cavity 62 and is used to accommodate the integrated circuit board 4 connected to the body 2. Figures 6 to 8 As shown, the container frame 33 includes a stop 34, a clearance space 35, a first elastic claw 36, and a container cavity 37. The stop 34 is located at the rear of the container frame 33 and extends along a first direction Z. The clearance space 35 is formed inside the stop 34. The first elastic claw 36 is located outside the stop 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, and its claw head is located at the front end of the claw body and has an inwardly and rearwardly facing claw surface. The front surface of its claw head is inclined outward along the first direction Z. The container cavity 37 is formed between the stop 34 and the first elastic claw 36. The container cavity 37 is used to accommodate the integrated circuit board 4 and provide a movement channel for the board 4' to be recycled. The container cavity 37 is divided into a front part and a rear part along the first direction Z. The substrate holder 33 has a support wall below the front part of the substrate cavity 37 to support the integrated circuit board 4 entering the front part of the substrate cavity 37. In this embodiment, "upper" refers to the direction away from the Earth's center along the vertical direction, and "lower" refers to the direction closer to the Earth's center along the vertical direction. Figure 43 As shown, the information extraction component 14 extends into the front of the cavity 37 and is elastic, with its front end forming a bevel to allow it to elastically deform and press against the input / output terminals on the integrated circuit board 4 when the integrated circuit board 4 enters the front of the cavity 37, thereby establishing an electrical connection between other modules and the integrated circuit board 4. The rear of the cavity 37 provides a movement channel for the board 4' to be recycled. Figure 4As shown, 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. Figure 2 , Figure 4 and Figure 9 As shown, a recycling chamber 38 is provided between the lower shell body 25 and the front cover 26. Along the first direction Z, the recycling chamber 20 is located in front of and isolated from the powder-containing chamber 18. Along the vertical direction, the recycling chamber 38 is located below the rear portion of the plate-containing chamber 37 and communicates vertically with the rear portion of the plate-containing chamber 37 to allow the plate to be recycled 4' to fall into the recycling 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 to be recycled 4' contained in the recycling chamber 38 can be easily recycled. Figure 4 As shown, the rear cover 27 is located at the rear end of the lower housing 16 and is fixedly connected to the lower housing 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.

[0096] like Figure 4 and Figure 5 As shown, the cover 6 is engaged with two guide rails 30, allowing the cover 6 to slide relative to the housing 5 in the second direction Y to open the toner inlet 22 and in the first direction Z to close the toner inlet 22. The outer side of the cover 6 is provided with an elastic sealing portion suitable for adhering tightly to the cavity wall of the bottle cavity 17, preventing toner contained in the toner cavity 18 from leaking into the bottle cavity 17 when the cover 6 closes the toner inlet 22.

[0097] See Figures 10 to 14 , Figures 10 to 14 The drive mechanism 13 in this embodiment is shown. For example... Figure 2 and Figure 10 As shown, the drive mechanism 13 includes a first rotating member 39, a bottle-part drive assembly 40, and a transmission assembly 41. The first rotating member 39 drives the photosensitive drum 7 to rotate. In this embodiment, the first rotating member 39 is a gear, with its lower part protruding from the lower housing body 25 to mesh with an external gear and obtain driving force from the outside. In this embodiment, the first rotating member 39 is the only power input end of the drive mechanism 13. The bottle-part drive assembly 40 drives the bottle part 49 of the toner bottle 3 to rotate. Figure 11 As shown, the bottle drive assembly 40 includes a second rotating member 42, a sliding connector 43, an energy storage member 44, a stop member 45, and a fastener 46. Among them, as... Figures 12 to 14As shown, the second rotating member 42 includes a rotating part 47 and a rotating shaft part 48. In this embodiment, the rotating part 47 is a gear and is clamped in the gap between the rear cover 27 and the base plate 28. The rotating shaft part 48 is fixedly connected to the rotating part 47 and supported by the rear cover 27 and the base plate 28. The front part of the rotating shaft part 48 extends out of the base plate 28 along the first direction Z and is provided with a radial protrusion along the radial direction. The sliding connector 43 is sleeved on the front part of the rotating shaft part 48 and is provided with a radial groove suitable for anti-rotation engagement with the radial protrusion. Of course, the sliding connector 43 and the rotating shaft part 48 can also achieve anti-rotation engagement through other non-rotational surface engagement methods. In this embodiment, "anti-rotation engagement" refers to an engagement method in which the two cannot move relative to each other in the rotational direction through non-rotational surface engagement. The sliding connector 43 is adapted to slide relative to the second rotating member 42 along the second direction Y and the first direction Z, and always anti-rotationally engages 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 substrate 28 along the second direction Y. Its function is to store energy when the sliding connector 43 moves along the second direction Y, and to push the sliding connector 43 to move along the first direction Z by releasing the energy. In some embodiments, the energy storage member 44, as an elastic member, can also be positioned between the sliding connector 43 and the second rotating member 42. In other embodiments, the energy storage member 44 can also be a magnetic member, having a magnetic interaction with the sliding connector 43. It can similarly achieve the function of storing energy when the sliding connector 43 moves along the second direction Y, and pushing the sliding connector 43 to move along the first direction Z by releasing the energy. When the energy storage member 44 is a magnetic member, it is generally fixed to the housing 4 or the second rotating member 42. The stop member 45 is used to limit the travel of the sliding connector 43 along 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 45 is fixed to the front end of the rotating shaft 48 by a fastener 46. Specifically, the front end of the rotating shaft 48 has a threaded hole, and the fastener 46 is a screw. The fastener 46 passes through the stop 45 and engages with the threaded hole of the rotating shaft 48, so that the stop 45 is fixed to the front end of the rotating shaft. The transmission assembly 41 is used to transmit power from the first rotating member 40 to the second rotating member 42, and also drives the stirring member 12 to rotate inside the powder-containing cavity 18. In this embodiment, the transmission assembly 41 includes a plurality of sequentially meshing transmission gears, the input end of which meshes with the first rotating member 40, and the output end of which meshes with the rotating part 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 known to those skilled in the art, such as a belt pulley transmission mechanism, as long as the linkage between the first rotating member 40 and the second rotating member 42 is achieved. The linkage between the first rotating member 40 and the second rotating member 42 means that the photosensitive drum (7) and the bottle part (49) are linked together.In this embodiment, "linkage" refers to two objects moving and stopping simultaneously through mechanical or other connection methods. This can be in the same direction or in opposite directions, and the speeds can be the same or different.

[0098] See Figure 15 , Figure 15 The toner bottle 3 and integrated circuit board 4 of this embodiment are shown. The toner bottle 3 is used to contain, transport, and supply toner to the toner inlet 22, and also to support the integrated circuit board 4. Figure 15 As shown, the toner bottle 3 includes a cap 50 in addition to the bottle portion 49. The bottle portion 49 is used to contain and transport toner. The cap 50 is used to supply toner to the toner inlet 22 and to support the integrated circuit board 4. In this embodiment, after the bottle portion 49 and the cap portion 50 are connected, the bottle portion 49 is adapted to rotate relative to the cap portion 50 in a first rotation direction ω.

[0099] See Figures 16 to 24 , Figures 16 to 24 The bottle portion 49 in this embodiment is shown. (As shown...) Figure 16 As shown, the bottle portion 49 includes a bottle body 51, a conveying component 52, and a sealing component 53. The bottle body 51 is generally manufactured using a blow molding process and is used to contain and convey toner along a first direction Z. Figure 17 and Figure 18As shown, the bottle body 51 extends along the second direction Y and sequentially includes an integrally connected bottle mouth portion 54 and bottle body portion 55. The bottle mouth portion 54 includes an integrally connected bottle mouth annular wall 56, bottle mouth flange 57, and bottle mouth end wall 58. The bottle mouth annular wall 56 is annular, and its central axis is consistent with the rotation axis of the bottle portion 49 and both extend along the first direction Z. The bottle mouth flange 57 is annular and protrudes outward from the rear end of the bottle mouth annular wall 56, and the bottle mouth end wall 58 is annular and protrudes inward from the front end of the bottle mouth annular wall 56, with the hollow portion of the bottle mouth end wall 58 forming the bottle mouth. The bottle body portion 55 extends along the second direction Y, and its front portion near the bottle mouth portion 54 tapers along the first direction Z to connect with the rear end of the bottle mouth annular wall 56. The inner surface of the front portion of the bottle body portion 55 is provided with two inwardly protruding stop protrusions 59, which are evenly distributed along the first rotation direction ω. The inner surface of the bottle body 55 has two inwardly protruding spiral protrusions 60, the central axes of which extend along the first direction Z and rotate in the same direction. A spiral groove 61 is formed between the same spiral protrusion 60 or between two adjacent spiral protrusions 60, extending from the rear of the bottle body 55 to the front of the bottle body 55 near the bottle mouth 54. The spiral protrusions 60 are configured such that when the bottle body 49 rotates along the first rotation direction ω, toner is conveyed from rear to front along the first direction Z in the spiral groove 61. The rear end surface of the bottle body 55 has a bottom groove 62, which extends radially and opens rearward. The bottom groove 62 is configured to allow a stop member 45 to extend into it along the first direction Z from its opening. When the sliding connector 43 rotates in the same or similar phase as the bottom groove 62, the bottom groove 62 is also configured to allow the sliding connector 43 to extend into it along the first direction Z from its opening to prevent rotational engagement between the sliding connector 43 and the bottle body 51. The conveyor 52 is adapted to connect to the bottle body 51. The conveyor 51 is used to convey toner from the bottle body 51 to the cap 49. Figure 19 and Figure 20As shown, the conveyor 52 includes an annular wall 63, an abutment flange 64, a first baffle 65, a second baffle 66, an abutment protrusion 67, a locking protrusion 68, and a spiral protrusion 69. The annular wall 63 is circular, with its central axis extending along a first direction Z, and is adapted to be inserted into the bottle body 51 from the bottle opening. The abutment flange 64 is circular, protruding outward from the front end of the annular wall 63, and is adapted to abut against the front surface of the bottle opening end wall 58 along a second direction Y. The first baffle 65 is used to output toner to the cap 50 when the bottle 49 rotates along a first rotation direction ω. The first baffle 65 is disposed at the front of the conveyor 52 and extends along the first direction Z. The front end of the first baffle 65 extends outward along the first direction Z from the abutment flange 64, and 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 stop at the front surface of the abutment flange 64. In a cross-section perpendicular to the first direction Z, the outer edge of the first baffle 65 abuts against the outer edge of the flange 64, and 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 distributed along the first rotation direction ω. The second baffle 66 is used to assist in stirring the toner, preventing it from clumping. The second baffle 66 is disposed at the front of the conveyor 52 and extends from the front surface of the flange 64 along the first direction Z. In a cross-section perpendicular to the first direction Z, the outer edge of the second baffle 66 abuts against the outer edge of the flange 64, and the inner edge of the second baffle 66 abuts against 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 the same group are located on one side of the two first baffles 65 and are evenly distributed between the two first baffles 65 along the first rotation direction ω. In this embodiment, each first baffle 65 and each second baffle 66 has reinforcing ribs on the back side facing away from the first rotation direction ω. The abutment protrusion 67 protrudes rearward 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 each group are evenly distributed along the first rotation direction ω, forming a phase angle between the two groups of abutment protrusions 67. The phase angle can preferably be 90 degrees, or other angles. Each group of two abutment protrusions 67 is used to abut and cooperate with two stop protrusions 59 respectively, so that when the bottle body 51 is driven by the bottle drive assembly 40 to rotate along the first rotation direction ω, it can push the conveyor 52 to rotate together along the first rotation direction ω. The locking protrusion 68 protrudes outward from the outer surface of the annular wall 63 and is located behind the abutment flange 64. The gap between the rear surface of the abutment flange 64 and the front surface of the locking protrusion 68 is adapted to the thickness of the bottle mouth end wall 58, so that when the conveyor 52 is connected to the bottle body 51, the bottle mouth end wall 58 is clamped between the abutment flange 64 and the locking protrusion 68, preventing the conveyor 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.A spiral protrusion 69 is formed by protruding inward from the inner surface of the annular wall 63 in a spiral shape. Its spiral direction is configured so that when the bottle portion 49 rotates along the first rotation direction ω, the toner moves along the first direction Z under the push of the spiral protrusion 69. In this embodiment, the number of spiral protrusions 69 is the same as the number of first baffles 65 and they correspond one-to-one. The front surface of the spiral protrusion 69 faces the first baffle 65 in a direction opposite to 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 it due to gravity when it detaches from the front end of the spiral protrusion 69. Figure 16 As shown, the sealing element 53 is an annular shape with thickness and is elastic at least in the first direction Z. The inner edge of the sealing element 53 is adapted to abut against the outer surface of the bottle neck annular wall 56, and the rear surface of the sealing element 53 is adapted to abut against the front surface of the bottle neck flange 57. In this embodiment, the sealing element 53 is connected to the bottle body 51 by fitting the sealing element 53 over the bottle neck annular wall 56 and abutting the rear surface of the sealing element 53 against the front surface of the bottle neck flange 57. The conveying element 52 is connected to the bottle body 51 by inserting the conveying element 52 into the bottle body 51 in the second direction Y with the abutting protrusion 67 facing the bottle neck until the bottle neck end wall 58 is clamped between the abutting flange 64 and the locking protrusion 68, and then rotating the bottle body 51 relative to the conveying element 52 in the first rotation direction ω, so that the stop protrusion 59 abuts against the abutting protrusion 67 in the first rotation direction ω. This embodiment includes two sets of abutment protrusions 67 to allow for a smaller angle of rotation of the conveyor 52 relative to the bottle body 51 during assembly of the bottle body 51 and the conveyor 52, thereby improving assembly efficiency. Figures 21 to 24As shown, after the bottle part 49 is connected, the rear surface of the sealing member 53 abuts against the front surface of the bottle mouth flange 57, the inner edge of the sealing member 52 abuts against the outer surface of the bottle mouth annular wall 56, and the bottle mouth end wall 58 is clamped between the abutting flange 64 and the locking protrusion 68, so that the conveying member 52 is fixed relative to the bottle body 51 in the first direction Z. The two abutting protrusions 67 of the same group are abutted by the corresponding stop protrusions 59 in the first rotation direction ω, so that the bottle body 51 can drive the conveying member 52 to rotate in the first rotation direction ω. When the stop protrusion 59 abuts against the abutting protrusion 67, the two spiral protrusions 69 are respectively set to correspond to the two spiral protrusions 60. Specifically, the front surface of the spiral protrusion 69 connects to the front end of the corresponding spiral groove 61, so that when the bottle rotates along the first rotation direction ω, the toner moving along the first direction Z through the spiral groove 61 can be smoothly transferred to the front surface of the spiral protrusion 69, and pushed by the spiral protrusion 69 to continue moving along the first direction Z until it falls from the front end of the spiral protrusion 69 onto the corresponding first baffle 65. Thus, the bottle 49 achieves the function of moving the toner from the bottle containing the toner in the first rotation direction ω to the first baffle 65 by rotating along the first rotation direction ω. Especially when there is less toner in the bottle 51, the toner will mainly concentrate in the spiral groove 61. At this time, the toner moves along the first rotation direction ω to the front surface of the spiral protrusion 69, and then detaches from the front end of the spiral protrusion 69 and falls onto the first baffle 65.

[0100] See Figures 25 to 30 , Figures 25 to 30 The cover 50 and integrated circuit board 4 in this embodiment are shown. Figure 25 As shown, the cover 50 includes a cover body 70, a resilient sealing element 71, and a sliding cover 72. (As...) Figure 26 and Figure 27As shown, the cover 70 has 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 70 has an operating unit 76 in front of the partition wall 73. The operating unit 76 has at least two operating parts 77, each of which is suitable for operation by different fingers of the same hand. In this embodiment, "operating part" refers to the part of the cover 70 that directly contacts the fingers. When there are two operating parts 77, the two operating parts 77 are oriented away from each other to be suitable for operation by the thumb and index finger respectively; when there are three operating parts 77, the three operating parts 77 can be arranged in a triangle to be suitable for operation by the thumb, index finger, and middle finger respectively, but at least two operating parts 77 are oriented away from each other. At least one operating part 77 has a pulling space 80 between it and the partition 73. The pulling space 80 is used for the fingertip to insert, so that the user can pull the toner bottle 3 in the first direction Z to remove the toner bottle 3 from the main body 2. In the operating unit 76, at least one operating part 77 also drives the second mating part 78 to move radially, so that the second mating part 78 can engage or disengage from the first mating part 29. Specifically, when two fingers apply force to the two operating parts 77, at least one of the operating parts 77 deforms radially inward, driving the corresponding second mating part 78 to move radially inward, and the second mating part 78 disengages from the first mating part 29; when the fingers release the force applied to the two operating parts 77, at least one of the operating parts 77 deforms radially outward, driving the corresponding second mating part 28 to move radially outward, and the second mating part 78 engages with the first mating part 29. In this embodiment, "radial deformation," "radial outward deformation," and "radial inward deformation" refer to deformations having at least a component perpendicular to the first direction Z; "radial movement," "radial outward movement," and "radial inward movement" refer to movements having at least a component perpendicular to the first direction Z. When the second mating part 78 engages with the first mating part 29, the cover 70 is fixed relative to the housing 5 along the second direction Y and the first direction Z; when the second mating part 28 disengages from the first mating part 29, the cover 70 can move relative to the housing 5 along the second direction Y or the first direction Z. In a preferred embodiment, when the second mating part 78 engages with the first mating part 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 rotation direction ω, thereby fixing the cover 70 relative to the housing 5. In another preferred embodiment, when the second mating part 78 engages with the first mating part 29, the cover 70 is fixed only relative to the housing 5 along the second direction Y and the first direction Z. At this time, the cover 70 should also be provided with other structures to engage with the housing 5 so that the cover 70 and the housing 5 are fixed along the first rotation direction ω.To enable the deformation of the operating part 77 to drive the corresponding second mating part 78 to move radially, the operating unit 76 is further provided with a driving part 79. The driving part 79 is used to transmit the radial deformation of the operating part 77 to the second mating part 78, causing the second mating part 78 to move radially. The driving part 79 may or may not be integrated with the operating part 77. The driving part 79 may or may not drive the second mating part 78 to move radially through deformation. When a finger applies force to the two operating parts 77 in opposite directions, at least one of the operating parts 77 deforms radially inward, driving the second mating part 78 to move radially inward through the corresponding driving part 79. When the finger releases the force applied to the two operating parts 77 in opposite directions, at least one of the operating parts 77 recovers its radial deformation outward, driving the second mating part 78 to move radially outward through the corresponding driving part 79. In a preferred embodiment, the second mating part 78 is located on the outer edge surface of the driving part 79, and the driving part 79 is integrally connected with the corresponding operating part 77 and deforms with the deformation of the corresponding operating part 77. In a preferred embodiment, the outer edge surface of the driving part 79 is configured such that when the driving part 79 recovers its deformation, its projection on the projection plane perpendicular to the second direction Y coincides with the projection portion of the outer edge surface of the rear wall 75. In a preferred embodiment, there is a gap between the driving part 79 and the partition wall 73 to facilitate the deformation of the driving part 79. In this embodiment, the operating unit 76 is provided with two operating parts 77, one second mating part 78, and one driving part 79. The two operating parts 77 of the operating unit 76 are opposite to each other and both extend along the second direction Y. The two operating parts 77 are adapted to be operated by the thumb and index finger respectively. Both operating parts 77 are adapted to deform radially inward when the finger exerts force, and there is a pulling space 80 between the two operating parts 77 and the partition wall 73. One of the operating parts 77 is integrated with the driving part 79, which is integrated with the front wall 74. The outer edge of the driving part 79 is configured such that its projection on the projection plane perpendicular to the first direction Z when the driving part 79 recovers its deformation partially coincides with the projection of the outer edge of the rear wall 75. At least a portion of the driving part 79 is spaced from the partition wall 73. The second mating part 78 is a protrusion on the outer edge of the driving part 79. When a finger applies force to the two operating parts 77 in opposite directions, at least one of the operating parts 77 deforms radially inward, causing the corresponding driving part 29 to deform radially inward, so that the second mating part 78 moves radially inward. The second mating part 78 disengages from the first mating part 29, or the toner bottle 3 can move along the second direction Y. When the finger relaxes and applies force to the two operating parts 77 in opposite directions, at least one operating part 77 deforms radially outward, causing the corresponding driving part 79 to deform radially outward, so that the second mating part 78 can extend into the first mating part 29 and engage with the first mating part 29. The cover 50 is not only limited along the second direction Y but also limited along the first rotation direction ω relative to the shell 5, that is, the cover 50 and the shell 5 are fixedly connected.Preferably, the rear surface of the second mating part 78 is configured to be inclined inward along the second direction Y. In this case, during the process of the toner bottle 3 being inserted into the body 2 along the second direction Y, the second mating part 78 is gradually pressed inward by the housing 5, causing the driving part 79 to deform inward. This also allows the toner bottle 3 to move along the second direction Y until the second mating part 78 engages with the first mating part 29. In other embodiments, when the first mating part 29 is designed to protrude from the cavity wall of the bottle cavity 17, the second mating part 78 is correspondingly designed as a hole or groove to allow the first mating part 29 to extend into and engage. For example... Figure 27As shown, in this embodiment, a rearward 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 adapted to abut against the front surface of the seal 53. Between the plane containing the rear surface of the partition wall 73 and the plane containing the sealing stop surface 81, the partition wall 73 and the rear wall 75 enclose a toner delivery cavity 82. The toner delivery cavity 82 has a rearward opening. The rear wall 75 is also provided with a toner delivery port 83 that communicates laterally with the toner delivery cavity 82. In this embodiment, the toner delivery port 83 penetrates 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 is also provided with a stirring blade 84 extending along the second direction Y. The stirring blade 84 is used to assist in stirring the toner delivered by the bottle part 48 rotating along the first rotation direction ω after the toner bottle 3 is connected, so that the toner does not clump. In this embodiment, the rear wall 75 is further provided with four circumferentially distributed second elastic claws 85. The second elastic claws 85 are located behind the sealing stop surface 81. The claw body of the second elastic claw 85 extends along the first direction Z, and its claw head is located at the front end of the claw body and has an inward and rearward inclined claw surface. The claw head also has a forward abutment surface. In this embodiment, the rear end of the rear wall 75 is further provided with a pulling part 86. The pulling part 86 protrudes radially outward from the outer edge surface of the rear wall 75, and its position in the circumferential direction corresponds to the position of the toner inlet 83 in the circumferential direction. In this embodiment, the pulling part 86 is designed as an elastic claw, its claw body extends along the second direction Y, and its claw head is located at the rear end of the claw body and has an outward and forward claw surface. The pulling part 86 is used to push the cover 6 to move relative to the housing 5 along the first direction Z until the toner inlet 22 is closed when the toner bottle 3 moves relative to the body 2 in the first direction Z. In other embodiments, the pulling part 86 can also be configured as a protrusion protruding from the outer surface of the rear wall 75. In this embodiment, a guide portion 87 is also provided on the front wall 74. The guide portion 87 protrudes radially outward from the outer edge surface of the front wall 74. The guide portion 87 is used to cooperate with the guide channel 20 to guide the toner bottle 3 during the process of inserting it into the body 2 and removing it from the body 2. In other embodiments, the guide portion 87 can also be provided on the rear wall 75. In other embodiments, the guide portion 87 and the guide channel 20 can be interchanged, that is, the guide portion 87 is provided on the housing 5, and the guide channel 20 is provided on the cover 70. In other embodiments, if the second mating portion 78 engages with the first mating portion 29, and only the cover 70 is fixed relative to the housing 5 in the second direction Y and the first direction Z, the guide channel 20 can be designed so that when the guide portion 87 abuts against the stop block 23, the guide portion 87 and the guide channel 20 engage in a non-rotational cooperation, so that the cover 70 is fixed relative to the housing 5 in the first rotation direction ω. Figure 26As shown, the cover 70 is also provided with two slide rails 88, both of which extend from the front wall 74 to the rear wall 75 along the second direction Y. The powder feeding port 83 is located between the two slide rails 88 in the circumferential direction. The slide rails 88 are radially protruding from the outer edges of the front wall 74 and the rear wall 75 and are used to cooperate with the sliding cover 72, allowing the sliding cover 72 to slide relative to the cover 70 along the second direction Y and the first direction Z. In this embodiment, a limiting protrusion 89 is also provided outwardly on the outer edge 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, and is located between the two slide rails 88 in the circumferential direction, used to limit the travel of the sliding cover 72 along the first direction Z. Figure 26 , Figure 28 and Figure 30 As shown, the cover 70 is also provided with a retainer 90, which is used to hold the integrated circuit board 4 and fix the integrated circuit board 4 relative to the cover 70. The retainer 90 is disposed at the front end of the cover 70 and protrudes from the outer edge of the front wall 74. On the outer side of the retainer 90 are a limiting block 91 and a third elastic claw 92 facing each other. The limiting block 91 has a rearward limiting surface, which is configured to be aligned vertically with the claw surface of the first elastic claw 36 after the integrated circuit board 4 enters the cavity 37. In this embodiment, the limiting surface is located in the middle of the two claw surfaces in the vertical direction. The claw body of the third elastic claw 92 extends along the second direction Y, and its claw head is disposed at the rear end of the claw body and has an outward and forward claw surface. The integrated circuit board 4 is adapted to be installed between the limiting surface of the limiting block 91 and the claw surface of the third elastic claw 92, so that it is limited relative to the cover 70 along the second direction Y. Figure 26 As shown, the cover 70 also includes a pushing part 93, which is located behind the toner inlet 83 and in front of the pulling part 86. The pushing part 93 protrudes radially from the outer edge of the rear wall 75 and is used to push the cover 6 relative to the housing 5 to move along the second direction Y when the toner bottle 3 is inserted into the body 2 in the second direction Y, thereby opening the toner inlet 22. In this embodiment, the pushing part 93 is designed as the rear end of the slide rail 88. In other embodiments, the pushing part 93 may also be provided independently. Figure 25 As shown, the elastic seal 71 is an elastic foam, which is fixed to the outer edges of the front wall 74 and the rear wall 75. The elastic seal 71 is located circumferentially between the two slide rails 88 and behind the limiting protrusion 89 along the first direction Z. The elastic seal 71 has a through hole 94 corresponding to and communicating with the powder feeding port 83. Figure 25 , Figure 28 and Figure 29As shown, the sliding cover 72 has a plate 95 with an arc-shaped cross-section. The inner surface of the rear end of the plate 75 has an inclined surface that slopes backward in the inward direction. It is adapted to engage with two slide rails 88, so that the sliding cover 72 is 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 backstop fitting part 96 and a blocking fitting part 97. The backstop fitting part 96 is located in front of the blocking fitting part 97. The backstop fitting part 96 is adapted to cooperate with the backstop part 32 so that the backstop part 32 can prevent the sliding cover 72 from following the cover 70 in the first direction Z when the toner bottle 3 is removed from the body 2 in the first direction Z, thereby causing the sliding cover 72 to slide relative to the cover 70 in the second direction Y to close the through hole 94. The blocking part 97 is adapted to cooperate with the blocking part 31 so that the blocking part 31 can prevent the sliding cover 72 from moving along the second direction Y with the cover body 70 when the toner bottle 3 is inserted into the body 2 along the second direction Y, so that the sliding cover 72 slides relative to the cover body 70 along the first direction Z until it hits the limiting protrusion 89 to open the through hole 94.

[0101] See Figures 31 to 33 , Figures 31 to 33 The toner bottle 3 connected in this embodiment is shown. The toner bottle 3 is connected by moving the cap 50 relative to the bottle 49 in the second direction Y with the stirring blade 84 facing the bottle opening. During this process, the inward and rearward inclined claw surface of the second elastic claw 85 abuts against the front end of the outer edge of the sealing member 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 abutment surface of the second elastic claw 85 in the first direction Z, thus completing the connection of the toner bottle 3. Figure 31 and Figure 32 As shown, after the toner bottle 3 is connected, the forward-facing contact surface of the second elastic claw 85 presses against the rear surface of the bottle mouth flange 57, causing the sealing member 53 to elastically abut against the sealing stop surface 81 of the cap 70, thereby achieving a sealed connection between the bottle part 49 and the cap part 50, and simultaneously limiting the bottle part 49 relative to the cap part 50 along the second direction Y. Because the bottle part 49 is engaged by four evenly distributed second elastic claws 85 along the circumferential direction, the bottle part 49 has a degree of freedom along the first rotation direction ω, and cannot detach radially from the cap 70. This allows the bottle part 49 to rotate relative to the cap part 50 along the first rotation direction ω. At this time, the stirring member 84 extends from the bottle mouth into the bottle mouth part 54 to stir the toner when the bottle part 49 rotates, and the first baffle 65 and the second baffle 66 extend into the toner delivery chamber 82. Figure 31 and Figure 33As shown, in this embodiment, after the toner bottle 3 is connected, the outer edges of the first baffle 65 and the second baffle 66 rotatably abut against the side wall of the toner delivery chamber 82 (i.e., the inner wall of the rear wall 75). The toner delivery port 83 is located on one side of the vertical plane where the rotation axis of the bottle 49 is located, and the toner delivery port 83 is inclined downward from the inside out. Similarly, the through hole 94 of the elastic seal 71 is also inclined downward from the inside out. Because the toner delivery port 83 is arranged laterally in this embodiment, the thickness of the entire developing device 1 in the vertical direction can be reduced. However, also because the toner delivery port 83 is arranged laterally, the toner cannot be transported from the bottom of the inner surface of the bottle 49 to the toner delivery port 83 by gravity alone. Instead, the first baffle 65 needs to lift the toner to the position of the toner delivery port 83 before it is output from the toner delivery port 83. Figure 33 It can be seen that when the outer edge of the first baffle 65 rotates along the first rotation direction ω to the inner lower edge of the toner feeding port 83, the first baffle 65 tilts downward from the inside out. This allows the toner that falls from the front end of the corresponding spiral protrusion 69 onto the first baffle 65 to be conveyed to the toner feeding port 83. In this embodiment, when the bottle 49 contains only a small amount of toner, the detailed process of the toner being output from the bottle body 51 through the through hole 94 in the toner bottle 3 is as follows: The bottle 49 rotates relative to the cap 50 along the first rotation 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. Since the front surface of the spiral protrusion 69 of the conveyor 52 is connected to the spiral groove 61, the toner is transferred from the spiral groove 61 to the front surface of the spiral protrusion 69. As the conveyor 52 is pushed by the bottle 51 and rotates along the first rotation direction ω, the toner is pushed by the spiral protrusion 69 to move along the first direction Z until 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 toner inlet 83. Since the upper surface of the first baffle 65 is in a downward tilted state from the inside out at this time, the toner enters the toner inlet 83 from the first baffle 65. Since both the toner inlet 83 and the through hole 94 are configured to be downward tilted from the inside out, the toner can be output from the through hole 94.

[0102] See Figures 34 to 43 , Figures 34 to 36 The process of loading the toner bottle 3 and the integrated circuit board 4 into the main body 2 is shown. Figures 37 to 43 The diagram illustrates the connection relationship between the toner bottle 3 and the 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 the integrated circuit board 4 into the main body 2 is divided into three steps. In step one, the toner bottle 3 and the integrated circuit board 4 move relative to the main body 2 from an initial state to a first state along the second direction Y. For example... Figure 34As shown, in the initial state, the integrated circuit board 4 is installed between the limiting block 91 and the third elastic claw 92 of the retainer 90. The toner bottle 3 and the integrated circuit board 4 move away from the body 2 along the first direction Z, and are aligned with the body 2 with the bottle body 51 extending along the second direction Y, the bottom groove 62 facing the bottle opening 21, and the guide part 87 aligned with the guide channel 20. The user pushes the front ends of the two operating parts 77 with their fingers, thereby pushing the toner bottle 3 and the integrated circuit board 4 to move relative to the body 2 along the second direction Y. The bottle body 51 enters the bottle cavity 17 through the bottle opening 21, and the guide part 87 is guided by the first channel of the guide channel 20 to move along the second direction Y until it hits the rear end of the first channel. At this time, the toner bottle 3 and the integrated circuit board 4 are in the first state. In the first state, the anti-reverse engagement part 96 passes over the rear end of the anti-reverse part 32 from below along the second direction Y, and the pulling part 86 passes over the rear end of the cover 6 from below along the second direction Y. In step two, the toner bottle 3 and the integrated circuit board 4 move from the first state to the second state relative to the main body 2. The user rotates the two operating parts 77 with their fingers, causing the toner bottle 3 and the integrated circuit board 4 to rotate along the first rotation direction ω. The guide part 87 is guided by the second channel of the guide channel 20 to rotate along the first rotation direction ω from the first end of the second channel to the second end of the second channel. At this time, the toner bottle 3 and the integrated circuit board 4 are in the second state. Figure 35As shown, when the toner bottle 3 and the integrated circuit board 4 are in the second state, the anti-reverse engagement part 96 rotates along the first rotation direction ω to the rear of the anti-reverse part 32, and the blocking engagement part 97 faces the blocking part 31 along the second direction Y. The pulling part 86 rotates along the first rotation direction ω to the rear of the cover 6, and the pushing part 93 faces the cover 6 along the second direction Y, so that the cover 6 is between the pulling part 86 and the pushing part 93, and the integrated circuit board 4 faces the cavity 37 along the second direction Y and is located in front of the cavity 37. The third elastic claw 92 faces the stop part 34 along the second direction Y. In step three, the toner bottle 3 and the integrated circuit board 4 move relative to the body 2 from the second state to the developing device 1 entering the working state. The user pushes the front ends of the two operating parts 77 with two fingers, causing the toner bottle 3 and integrated circuit board 4 to move relative to the main body 2 along the second direction Y. During this process, the two fingers can apply force to the two operating parts 77 in opposite directions, causing the driving part 79 to deform radially inward. Alternatively, the two fingers can not apply force to the two operating parts 77 in opposite directions, and the driving part deforms radially inward through the engagement of the rear surface of the second mating part 78 with the housing 5, allowing the second mating part 78 to enter the bottle cavity 17. During this process, the guide part 87 is guided by the third channel of the guide channel 20 to move along the second direction Y from the front end of the third channel to the stop block 23. At this time, the second mating part 78 is facing the first mating part 29, and the driving part 79 returns to its original shape, allowing the second mating part 78 to extend into the first mating part 29. The cover 70 is fixed to the housing 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 connector 43, the stop 45 and the sliding connector 43 enter the bottle bottom groove 62, and the bottle part 49 is engaged with the sliding connector 43 to prevent rotation. If the rotation phase of the bottle bottom groove 62 is different from the rotation phase of the sliding connector 43, the stop 45 enters the bottle bottom groove 62, the rear surface of the bottle body 51 presses against the front surface of the sliding connector 43, causing the sliding connector 43 to slide along the second direction Y. The energy storage member 44 stores energy until the sliding connector 43 is driven by the second rotating member 42 to rotate along the first rotation direction ω until its phase is the same as or close to the phase of the bottle bottom groove 62. Then, the energy storage member 44 releases energy and pushes the sliding connector 43 to slide along the first direction Z until the sliding connector 43 enters the bottle bottom groove 62, and the bottle part 49 is engaged with the sliding connector 43 to prevent rotation. At this time, one end of the bottle portion 49 is supported by the cap portion 50 and has the degree of freedom to rotate in the first rotation 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 in the first rotation direction ω. Figure 40 As shown, in the third step, the pushing part 93 pushes the cover 6 to slide relative to the housing 5 along the second direction Y, thereby opening the powder inlet 22, as... Figure 41As shown, the blocking part 31 abuts against the blocking mating part 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 against the limiting protrusion 89. During the process of the sliding cover 72 opening the through hole 94, the elastic sealing member 71 radially deforms to abut against the cavity wall of the bottle cavity 17, allowing the toner inlet 83 to seal and connect with the toner inlet 22 through the through hole 94, so that toner can enter the toner cavity 18 from the toner bottle 3 without leaking into the interior of the body 2. Figure 43 As shown, the third elastic claw 92 is blocked by the stop part 34. Due to the inclined surface cooperation between the two, the third elastic claw 92 elastically deforms and extends into the clearance space 35 as the toner bottle 3 moves along the second direction Y. The third elastic claw 92 avoids the first elastic claw 36. The integrated circuit board 4 is pushed by the limiting block 91 to move along the second direction Y, causing the first elastic claw 36 to deform outward. During this process, the information extraction component 14 also deforms outward in contact with the integrated circuit board 4 until the integrated circuit board 4 enters the front part of the receiving cavity 37. The first elastic claw 36 returns to its original deformation, and its claw head is located directly in front of the integrated circuit board 4. The information extraction component 14 presses against the input and output terminals on the integrated circuit board 4, thereby establishing an electrical connection between other modules and the integrated circuit board 4. If the toner bottle 3 and the integrated circuit board 4 are not being installed into the body 2 for the first time, in this case, before the toner bottle 3 and the integrated circuit board 4 are installed into the body 2 this time, when the toner bottle 3 was removed from the body 2 last time, the recycling plate 4' was blocked by the first elastic claw 36 and was housed in the front part of the receiving cavity 37. In the third step, the integrated circuit board 4 pushes the plate to be recycled 4' along the second direction Y, causing the plate to be recycled 4' to move from the front of the container cavity 37 to the rear of the container cavity 37, and then falls into the recycling cavity 38 through the channel connecting the rear of the container cavity 37 to the recycling cavity 38 to wait for recycling.

[0103] The process of removing the toner bottle 3 from the main body 2 also includes three steps. In the first step, the user applies force to the two operating parts 77 in opposite directions. The operating parts 77 cause the driving part 79 to deform, and the second engaging part 78 disengages from the first engaging part 29. At the same time, the user's fingertip or other part extends into the pulling space 80 and pulls the toner bottle 3 along the first direction Z, so that the toner bottle 3 moves relative to the main body 2 from the working state to the second state along the first direction Z. During this process, the guide part 87 is guided by the third channel of the guide channel 20 to move along the first direction Z to the front end of the third channel. The pulling part 86 pulls the cover 6 along the first direction Z until the cover 6 closes the toner inlet 22. The stop part 32 abuts against the stop engaging part 96, preventing the sliding cover 72 from moving along the first direction Z, so that the sliding cover 72 moves relative to the cover body 70 along the second direction Y until the sliding cover 72 closes the through hole 94. During this process, the inclined surface of the inner rear surface of the plate 95 engages 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. At the same time, 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, unable to drive the integrated circuit board 4 to move in the first direction Z. Thus, the integrated circuit board 4 is left in the front of the cavity 37 to form a plate to be recycled 4'. In the second step, the user rotates the two operating parts 77 to drive the toner bottle 3 to rotate away from the first rotation direction ω, so that the toner bottle 3 moves from the second state to the first state. During this process, the guide part 87 is guided by the second channel of the guide channel 20 to rotate away from the first rotation direction ω and move from the second end of the second channel to the first end of the second channel. During this process, the anti-reverse engagement part 96 rotates away from the first rotation direction ω to the rear and lower part of the anti-reverse part 32, and the pulling part 86 rotates away from the first rotation direction ω to the rear and lower part of the cover 6. In the third step, the user's finger is inserted into the pulling space 80 and pulled along the first direction Z, so that the toner bottle 3 can move relative to the body 2 from the first state to the initial state along the first direction Z. During this process, the anti-reverse engagement part 96 passes over the anti-reverse part 32 from below along the first direction Z, and the pulling part 86 passes over the cover 6 from below along the first direction Z, until the toner bottle 2 separates from the body 3 and returns to the initial state.

[0104] The printing device in this embodiment uses the developing device 1 of this embodiment.

[0105] In this embodiment, the toner inlet 83 is located on one side of the vertical plane where the rotation axis of the bottle part 49 is located. That is, the toner inlet 83 is arranged laterally, and the toner is no longer delivered from the toner inlet 83 by gravity. The toner-containing cavity 18 of the body 2 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 beneficial to the miniaturization of the printing equipment.

[0106] In this embodiment, the bottle 49 and the photosensitive drum 7 are linked together, thus eliminating the need for a low-toner sensor, a corresponding controller, and a separate drive mechanism for rotating the bottle 49 within the toner 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 printing media, the linkage between the photosensitive drum 7 and the bottle 49 establishes a direct correlation between toner replacement needs and the amount of printing media. This makes toner bottle 3 replacement reminders very convenient, eliminating the need to check the remaining toner level in the bottle 3. This further simplifies the structure of the developing device 1, improves reliability, and reduces costs, providing more possibilities for the widespread adoption of laser printers and copiers.

[0107] In this embodiment, the first rotating component 39 is exposed outside the housing 5, allowing it to receive power from the outside. This makes the first rotating component 39 the only rotating component in the transmission mechanism 13 that receives external drive, which helps reduce structural complexity and save costs. The stirring component 12 located in the powder-containing cavity 18 is driven by the transmission assembly 41. Therefore, the entire transmission mechanism 13 drives at least the photosensitive drum 7, the bottle 49, and the stirring component 12, further reducing structural complexity and saving costs.

[0108] In this embodiment, the bottle drive assembly 40 and the cap 70 are located at the two ends of the bottle 51 along the first direction Z, which significantly improves the impact of vibration caused by the joint rotation of the bottle drive assembly 40 and the bottle 51 on the output toner of the cap 70, and improves the sealing problem caused by vibration when the toner is output from the toner bottle 3 to the body 2.

[0109] In this embodiment, the sliding connector 43 can slide relative to the second rotating member 42, which eliminates the need for the toner bottle 3 to establish an anti-rotation engagement with the bottle drive assembly 40 when it is fully inserted into the body 2. This is because if the toner bottle 3 must establish an anti-rotation engagement with the bottle drive assembly 40 when it is fully inserted, the rear end of the bottle body 51 would need to be equipped with a finely inclined guide structure so that the bottle 49 can maintain an anti-rotation engagement with the bottle drive assembly 40 regardless of its rotational phase relative to the body 2. In this embodiment, if the rotational phase of the bottle 49 is different 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 along the second direction Y to store energy in the energy storage member 44. This continues until the second connector 42 drives the sliding connector 43 to rotate to a rotational phase that is the same as or close to the rotational phase of the bottle 49. At this point, the energy storage member 44 releases energy, driving the sliding connector 43 to move along the first direction Z and insert into the bottle bottom groove 62, where it engages with the anti-rotation engagement. Therefore, this embodiment simplifies the structure of the bottle 51, makes it easier to process, and is suitable for blow molding. In this embodiment, the energy storage component 44 uses a spring, resulting in lower cost and a simpler structure.

[0110] In this embodiment, the toner feeding chamber 82 and the toner feeding port 83 are laterally connected, and the outer edge of the first baffle 65 abuts against the side wall of the toner feeding chamber 82. This not only agitates the toner but also facilitates the lifting of the toner to the toner feeding port 83. When the outer edge of the first baffle 65 rotates to align with the lower edge of the toner feeding port 83, the first baffle 65 tilts downwards in an inward-outward direction, which facilitates the transfer of the toner to the toner feeding port 83 by gravity after it has been lifted. The toner feeding port 83 tilts downwards in an inward-outward direction, which also facilitates the outward delivery of toner from the toner feeding port 83.

[0111] In this embodiment, the bottle body 51 and the conveyor 52 are manufactured separately, so that the bottle body 51 can be manufactured by blow molding, which helps to reduce structural complexity and manufacturing difficulty.

[0112] In this embodiment, the bottle body 51 and the conveyor 52 are fixed along the first direction Z by the interlocking connection between the bottle mouth end wall 58 and the abutment flange 64 and the locking protrusion 68. This facilitates the connection between the conveyor 52 and the bottle body 51. That is, when the conveyor 52 is inserted into the bottle body 51 along the second direction Y, the locking protrusion 68 will move inward due to deformation until it passes the bottle mouth end wall 58, thus locking the bottle body 51 and the conveyor 52 together. Therefore, the connection between the conveyor 52 and the bottle 51 is more convenient, which helps to improve assembly efficiency.

[0113] In this embodiment, the front surface of the spiral protrusion 69 of the conveyor 52 abuts against the spiral groove 61, allowing the toner moving along the first direction Z to continue moving along the first direction Z on the conveyor 52 by being pushed by the spiral protrusion 69. The front end of the spiral protrusion 69 faces away from the first rotation direction ω and toward the first baffle 65, allowing the first baffle 65 to receive toner falling from the front end of the spiral protrusion 69. This facilitates the effective 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 then conveys it to the toner inlet 83 through the first baffle 65, thereby avoiding waste.

[0114] In this embodiment, the bottle body 51 is provided with a stop protrusion 59, which abuts against the abutment protrusion 67 along the first rotation direction ω, thereby causing the bottle body 51 to drive the conveyor 52 to rotate along the first rotation direction ω. This is beneficial because when the conveyor 52 is inserted into the bottle body in a direction opposite to the second direction Y, it does not need to be aligned along the first rotation direction ω; it only needs to be inserted and then rotated to achieve the effect of rotating with the bottle body 51 along the first rotation direction ω. The abutment protrusion 67 is divided into two groups, and the two groups form a phase angle, which helps to reduce the rotation angle and improve production efficiency when assembling the bottle body 51 and the conveyor 52.

[0115] In this embodiment, the front surface of the second elastic claw 85 abuts against the rear surface of the bottle neck flange 57, and the sealing member 53 elastically abuts against the sealing stop surface 81, thereby limiting the bottle portion 49 relative to the cap body 70 along the first direction Z. It is well known that while elastic claw engagement is convenient for assembly, gaps often exist after engagement. However, in this patent, a sealing member 53 with elasticity along the first direction Z is provided between the claw head of the second elastic claw 85 and the sealing stop surface 81. Therefore, not only can axial limiting be achieved, but also a sealed connection between the bottle portion 49 and the powder feeding chamber 82 can be achieved. At least two second elastic claws 85 evenly distributed along the circumferential direction can not only restrict the bottle portion 49 from radially disengaging from the cap body 70, but also provide the bottle portion 49 with the freedom to rotate relative to the cap body 70 along the first rotation direction ω. Therefore, it is not only convenient for assembly, but also provides a good sealing effect after establishing a rotational connection.

[0116] In this embodiment, the toner inlet 83 is adjacent to the partition wall 73, so that toner will not remain at the front end of the toner delivery chamber 82.

[0117] In this embodiment, the rear surface of the claw head of the second elastic claw 85 is inclined inward along the first direction Z. This allows the claw head to automatically deform radially outward when the bottle part 49 moves along the first direction Z towards the cap 70, due to its engagement with the inclined surface of the bottle part 49. This enables the sealing member 53 and the bottle mouth flange 57 of the bottle part 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 returns to its original shape and abuts against the rear surface of the bottle mouth flange 57, achieving rapid assembly and improving assembly efficiency.

[0118] In this embodiment, the operation unit 76 has at least two operation parts 77 suitable for direct contact by different fingers of the same hand. The orientation of the at least two operation parts 77 is opposite to each other to facilitate operation by the thumb and any other finger, allowing different fingers of the same hand to operate each operation part 77. Thus, the operation unit 76 can realize the operation of inserting and removing the toner bottle 3 by setting a small operating space. Since the cover 70 is located at the front end of the toner bottle 3 along the first direction Z and the operation unit 76 is located at the front end of the cover, the toner bottle 3 can be operated from the end of the toner bottle 3 by finger operation, thereby enabling the toner bottle 3 to be inserted into the housing 5 along its extension direction. This results in a smaller opening in the housing 5, making it less likely for objects to enter the body and cause malfunction of the body 2. A pulling space 80 is formed behind at least one operation part 77, suitable for the fingertip of the corresponding finger to enter, so that the finger can be inserted 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 to the two opposing operating parts 77, the second mating part 78 can be driven to move radially relative to the cover 70. This allows the second mating part 78 to engage or disengage with the first mating part 29, 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 part 79 and the operating part 77 are integrated, and the radial deformation of the operating part 77 causes the driving part 79 to also deform radially. The second mating part 78 is disposed on the outer edge surface of the driving part 79, facilitating engagement or disengagement with the first mating part. The driving part 79 has at least a partial deformation gap with the partition wall 73, which is beneficial for the deformation of the driving part. The outer edge surface of the driving part 79 partially overlaps with the outer edge surface of the rear wall 75 during the recovery deformation, which allows the second mating part 78 to engage or disengage with the first mating part 22 with only a small stroke, reducing the amount of force required from the fingers on the operating part 77. The second mating part 78 is configured to be protruding and its rear surface is inclined outward along the first direction. When the toner bottle 3 is inserted into the body 2 along the second direction Y, it is not necessary to apply force to the two opposing operating parts 77. The second mating part 78 can be forced to deform the driving part 79 and enter the bottle cavity 17 simply by engaging with the inclined surface of the cavity wall of the bottle cavity 17.

[0119] In this embodiment, the guide channel 20 and the guide part 87 cooperate to guide the process of inserting the toner bottle 3 into the body 2, making it easier for the user to replace the toner bottle.

[0120] In this embodiment, the elastic seal 71 abuts against the cavity wall of the container cavity 17 when the sliding cover 72 opens the powder feeding port 83, which can better seal and connect the powder feeding port 83 with the powder inlet 22 and prevent powder leakage.

[0121] 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 against the elastic seal 71, thus 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.

[0122] In this embodiment, by providing a blocking engagement portion 97 and a backstop engagement portion 96 protruding from the outer surface of the plate 95, the gap between the blocking portion 31 and the backstop portion 32 can be reduced, which is beneficial to further reduce the length of the developing apparatus 1 along the first direction Z.

[0123] 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, making it difficult for foreign objects to enter the body and cause malfunctions.

[0124] In this embodiment, during the insertion of the toner bottle 3 into the body 2, the sliding cover 72 opens the through hole 94 by the blocking part 31 abutting against the blocking fitting part 97, and the toner inlet 22 is opened by the pushing part 93 abutting against the cover 6, thus preventing toner leakage during insertion. During the removal of the toner bottle 3 from the body 2, the sliding cover 72 closes the through hole 94 by the anti-reverse part 32 abutting against the anti-reverse fitting part 96, and the toner inlet 22 is closed by the pulling part 86 abutting against the cover 6, thus preventing toner leakage during removal.

[0125] In this embodiment, during the process of inserting the toner bottle 3 into the body 2, the anti-reverse engagement part 96 passes over the anti-reverse part 32 from below along the second direction Y or the first direction Z, and the pulling part 86 passes over the cover 6 from below along the second direction Y or the first direction Z. This can prevent the uncertainty of movement caused by interference between the anti-reverse part 32 and the anti-reverse engagement part 96 and interference between the pulling part 86 and the cover 6, thereby increasing the certainty of the action and its effect, and making it more convenient for the user to use.

[0126] This embodiment enables the recycling of integrated circuit board 4, which not only avoids waste but also helps to determine whether to use unauthorized toner bottles 3 to replenish toner by analyzing the model and stored information of integrated circuit board 4, and based on this, determine the specific plan for repairing the printing equipment.

[0127] In this embodiment, by setting a limiting block 91 and a third elastic claw 92, the integrated circuit board 4 is held on the toner bottle 3 when the toner bottle 3 is not inserted into the body 2, which facilitates the correspondence between the integrated circuit board 4 and the toner bottle 3. By setting a stop part 34, the third elastic claw 92 is elastically deformed, allowing the integrated circuit board 4 to smoothly enter the front part of the receiving cavity 37. By setting the third elastic claw 92 to prevent the integrated circuit board 4 from exiting, the integrated circuit board 4 is left in the receiving cavity 37. By setting the rear part of the receiving cavity 37 to be vertically connected to the recycling cavity 38, the plate to be recycled 4' can enter the recycling cavity 38 to wait for recycling. By the new integrated circuit board 4 pressing against the plate to be recycled 4', the plate to be recycled 4' can move through the rear part of the receiving cavity 37 into the recycling cavity 38.

[0128] In this embodiment, the process of loading the toner bottle 3 into the main body 2 automatically realizes the recycling of the integrated circuit board 4, without causing trouble for the user.

[0129] Example 2

[0130] The difference between Embodiment 2 and Embodiment 1 lies in the following: the housing 5 in Embodiment 2 is different from the housing 5 in Embodiment 1; the cover 50 in Embodiment 2 is different from the cover 50 in Embodiment 1; and the method of installing the toner bottle 3 and the integrated circuit board 4 into the body 2 in Embodiment 2 is different from the method of installing the toner bottle 3 into the body 2 in Embodiment 1. Specifically:

[0131] See Figure 44 , Figure 44 The housing 5 in this embodiment is shown. (As shown...) Figure 44 As shown, 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 part 29, which are all holes. In this embodiment, the stop part 32 is no longer provided in front of the blocking part 31, but 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, and its claw head is set inward and rearward. The front surface of its claw head is inclined inward along the second direction Y. The fourth elastic claw 98 is configured to cooperate with the stop mating part 96. In this embodiment, the housing 5 is also 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 along the first direction Z after the powder inlet 22 is closed.

[0132] See Figure 45 and Figure 46 , Figure 45 and Figure 46 The cover 50 in Embodiment 2 is shown. (As shown...) Figure 45 and Figure 46As shown, in this embodiment, in the operating unit 76 of the cover 70, both operating parts 77 are integrated with the corresponding driving parts 79. Each of the two driving parts 79 has a second mating part 78, which protrudes radially from the outer edge of the driving part 29. The two second mating parts 78 are opposite to each other and are respectively adapted to engage with the corresponding first mating part 29. In this embodiment, a fifth elastic claw 99 is provided behind the pushing part 93. The claw body of the fifth elastic claw 99 extends along the second direction Y, with its claw head facing forward and outward, and the rear surface of the claw head inclined inward along the second direction Y. In this embodiment, the plate 95 of the sliding cover 72 is the blocking mating part 97, and the front surface of the anti-reverse mating part 96 on the plate 95 is inclined outward along the second direction Y, and its rear surface is inclined inward along the second direction Y. In this embodiment, the cover 70 also has a second blocking block at the rear end of the slide rail 88. The second blocking block is used to prevent the sliding cover 72 from continuing to move relative to the cover 70 along the second direction Y after the through hole 94 is closed.

[0133] See Figures 47 to 51 , Figures 47 to 51 The structure of the developing apparatus 1 in the working state in this embodiment is shown. Figure 47 As shown, in this embodiment, the process of installing the toner bottle 3 and integrated circuit board 4 into the body 2 consists of only one step: driving the toner bottle 3 and integrated circuit board 4 to move from the initial state along the second direction Y until the guide part 87 moves from the front end of the guide channel 20 to the rear end of the guide channel 20, at which point the developing device 1 is in working condition. During this process, a finger can deform the two operating parts 77 to bring them closer together, allowing the two second mating parts 78 to move radially inward by the corresponding driving parts 79. Alternatively, the finger can not apply force to the two operating parts 77; the driving parts 79 can be deformed radially inward by the contact between the second mating parts 78 and the inclined surface of the housing 5, allowing the second mating parts 78 to enter the bottle cavity 17. Figures 48 to 50 As shown, during this process, when the fifth elastic claw 99 abuts against the cover 6, because its rear surface is inclined inward along the second direction Y, the fifth elastic claw 99 deforms inward and passes over the cover 6 until its claw head is behind the cover 6, after which the fifth elastic claw 99 returns to its deformed state. Figure 51 As shown, during this process, because the rear surface of the anti-reverse engagement 96 is inclined inward along the second direction Y, and the front surface of the claw head of the fourth elastic claw 98 is inclined inward along the second direction Y, when the anti-reverse engagement 96 and the fourth elastic claw 98 come into contact, the fourth elastic claw 98 deforms outward until the anti-reverse engagement 96 passes the claw head of the fourth elastic claw 98, after which the fourth elastic claw 98 returns to its original shape. During this process, the blocking part 31 abuts against the blocking engagement 97, preventing the sliding cover 72 from moving along the second direction Y, and moves relative to the cover body 70 along the first direction Z until it opens the through hole 94 and abuts against the limiting protrusion 89.

[0134] In this embodiment, the process of removing the toner bottle 3 from the body 2 consists of only one step. In this step, two fingers apply force to the two operating parts 77 of the toner bottle 3 in the working state, causing the operating parts 77 to deform and move closer to each other. This causes the two mating parts 78 to move radially inward by the corresponding driving parts 79, disengaging the second mating part 78 from the first mating part 29. At the same time, two fingers partially extend into the pulling space 80, pulling the toner bottle 3 from the middle state along the first direction Z. The guide part 87 moves from the rear end of the guide channel 20 to the front end of the guide channel 20 until it disengages from the guide channel, and the toner bottle 3 returns to its initial state relative to the 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 toner inlet 22 and abuts against the first blocking block. Because the forward-facing and outward-facing claw surface of the fifth elastic claw 99 is inclined outward along the second direction Y, after the cover 6 is blocked by the first blocking block, the fifth elastic claw 99 is forced to deform inward, causing its claw head to pass over the rear end of the cover 6 and abut against the surface of the cover 6 until it detaches from the cover 6, at which point the fifth elastic claw 99 returns to its original shape. During this process, the fourth elastic claw 98 blocks the anti-reverse engagement part 96, preventing the sliding cover 72 from sliding along the first direction Z, and causing it to slide relative to the cover body 70 along the second direction Y to close the through hole 94 and abut against the second blocking block. Because the front surface of the anti-reverse engagement part 96 is inclined outward along the second direction Y, after the sliding cover 72 is blocked by the second blocking block, the fourth elastic claw 98 is forced to deform outward, allowing the anti-reverse engagement part 96 to pass over the claw head of the fourth elastic claw 98 along the first direction Z, at which point the fourth elastic claw 98 returns to its original shape.

[0135] The printing device in this embodiment uses the developing device 1 of this embodiment.

[0136] In this embodiment, by setting a first blocking block, the fifth elastic claw 99 that cooperates with the cover 6 can pass over the cover 6 after the cover 6 closes the powder inlet 22; by setting a second blocking block, the fourth elastic claw 98 that cooperates with the sliding cover 72 can pass over the sliding cover 72 after the sliding cover 72 closes the powder delivery outlet 83.

[0137] In this embodiment, the steps of installing the toner bottle 3 and the integrated circuit board 4 into the body 2 and removing the toner bottle 3 from the body 2 in the developing apparatus 1 each require only one step and both involve movement along the second direction Y or the first direction Z. Therefore, assembly and disassembly are convenient, and the user's learning cost is low. Furthermore, during this process, neither the toner bottle 3 nor the housing 5 will leak toner.

[0138] The description of the above specification and embodiments is used to explain the scope of protection of this application, but does not constitute a limitation on the scope of protection of this application.
