Description

Technical Field

[0001] This utility model relates to the field of printing consumables technology, and in particular to a toner hopper and developing device. Background Technology

[0002] The developing unit is a core consumable component in imaging equipment such as printers and copiers. It is mainly used to hold and transfer toner (developer) to ensure the precise execution of the developing process. The toner hopper is the core component of the developing unit, which is specifically used to load toner and work with the developing roller to complete the developing work.

[0003] The existing toner cartridge structure of the developing device has components such as the toner filling section and handle protruding outward from the cartridge wall. This not only results in an awkward and uncoordinated structure that is prone to damage, but also causes the cartridge wall to be positioned close to the center of the cartridge, resulting in a very small toner loading cavity. This necessitates frequent disassembly and refilling of the toner during printing, which is time-consuming, laborious, and leads to poor printing results. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a toner hopper and developing device. The toner hopper has a regular and coordinated structure, is not easily damaged, has a large toner loading capacity, and is time-saving and labor-saving to use, resulting in good user experience.

[0005] This utility model provides a powder hopper, comprising: an upper hopper body, including a first upper hopper wall, a second upper hopper wall, and a third upper hopper wall arranged intersecting each other, wherein the first upper hopper wall has a powder filling hole protruding inward, and the deviation distance between the axis of the second upper hopper wall and the powder filling hole satisfies 50mm < L1 ≤ 70mm; and a lower hopper body, communicating with the upper hopper body, including a first lower hopper wall arranged parallel to the first upper hopper wall and a second lower hopper wall arranged parallel to the second upper hopper wall, wherein the deviation distance between the second lower hopper wall and the second upper hopper wall satisfies 2mm < L2 ≤ 5mm, the second lower hopper wall has an operating part protruding outward and a recessed part arranged inward, and a receiving cavity is formed between the operating part and the recessed part.

[0006] In a preferred embodiment of this utility model, the deviation distance between the centerline of the first upper compartment wall and the centerline of the upper compartment body satisfies 200mm<L3≤250mm.

[0007] In a further preferred embodiment of this utility model, the deviation distance between the axis of the third upper chamber wall and the powder filling hole satisfies 20mm < L4 ≤ 30mm.

[0008] In a further preferred embodiment of this utility model, the deviation distance between the first lower compartment wall and the first upper compartment wall satisfies 2mm < L5 ≤ 5mm.

[0009] In a further preferred embodiment of the present invention, the upper compartment further includes a first connecting wall, and the lower compartment further includes a second connecting wall, wherein the first connecting wall and the second connecting wall are connected by being fastened together vertically.

[0010] In a further preferred embodiment of this utility model, the upper chamber body further includes an inclined wall, the upper end of which is connected to the third upper chamber wall, the side end of which is connected to the first upper chamber wall, and the lower end of which is connected to the first connecting wall. The upper end has the smallest axial distance from the powder filling hole, and the lower end has the largest axial distance from the powder filling hole.

[0011] In a further preferred embodiment of this utility model, the distance between the lower end and the axis of the powder feeding hole satisfies 60mm < L6 ≤ 80mm.

[0012] In a further preferred embodiment of the present invention, one end of the second upper compartment wall is provided with a positioning guide groove, and the positioning guide groove passes through the third upper compartment wall.

[0013] In a further preferred embodiment of this invention, the accommodating cavity is elongated.

[0014] This utility model also provides a developing apparatus, which includes: a waste toner hopper and a toner hopper as described in any of the above claims, wherein the waste toner hopper is connected to the toner hopper.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] The powder hopper provided by this utility model has a regular and coordinated upper and lower hopper structure. The powder filling hole is located inside the first upper hopper wall, making it less susceptible to damage from collisions. Furthermore, the deviation distance between the first upper hopper wall with the powder filling hole and the centerline of the upper hopper is increased, thus increasing the length of the upper hopper. Additionally, the deviation distance between the second upper hopper wall and the axis of the powder filling hole is also increased to 50mm < L1 ≤ 70mm, thus increasing the width of the upper hopper. Further, the deviation distance between the second lower hopper wall and the second upper hopper wall satisfies… 2mm < L2 ≤ 5mm, meaning the deviation distance between the second lower chamber wall and the axis of the toner filling hole also increases to 52mm < L1 + L2 ≤ 75mm, increasing the width of the lower chamber. Furthermore, the operating part and the recessed part on the second lower chamber wall form a receiving cavity, which reduces the overall weight of the toner chamber and easily accommodates the hand, making operation easy without interference. The upper and lower chambers of this toner chamber have a large toner loading capacity, eliminating the need for frequent disassembly and toner refilling, saving time and effort in operation, and providing a good user experience.

[0030] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments: Example

[0031] See Figures 1-6 This embodiment provides a toner hopper 100. The toner hopper 100, which is loaded with toner, is connected to a waste toner hopper and assembled to form a developing device. This device is then installed in a printing machine for developing operations. Specifically, the toner hopper 100 includes:

[0032] The upper compartment 10 includes a first upper compartment wall 11, a second upper compartment wall 12 and a third upper compartment wall 13 arranged intersecting each other, forming a right angle or an obtuse angle. The first upper compartment wall 11 has a powder filling hole 111 protruding inward. The deviation distance between the axis 111a of the second upper compartment wall 12 and the powder filling hole 111 satisfies 50mm < L1 ≤ 70mm.

[0033] The lower compartment 20 is vertically connected to the upper compartment 10. The lower compartment 20 includes a first lower compartment wall 21 arranged parallel to the first upper compartment wall 11 and a second lower compartment wall 22 arranged parallel to the second upper compartment wall 12. The deviation distance between the second lower compartment wall 22 and the second upper compartment wall 12 satisfies 2mm < L2 ≤ 5mm. The second lower compartment wall 22 has an operating part 221 protruding outward and a recessed part 222 inward, and a receiving cavity 30 is formed between the operating part 221 and the recessed part 222.

[0034] Using the aforementioned powder hopper 100, the upper hopper body 10 and lower hopper body 20 are structurally arranged in a regular and coordinated manner. The powder filling hole 111 is located inside the first upper hopper wall 11, making it less susceptible to damage from collisions. Furthermore, the deviation distance between the first upper hopper wall 11 with the powder filling hole 111 and the centerline 10a of the upper hopper body 10 is increased, thereby increasing the length of the upper hopper body 10. Additionally, the deviation distance between the second upper hopper wall 12 and the axis 111a of the powder filling hole 111 is also increased to 50mm < L1 ≤ 70mm, thereby increasing the width of the upper hopper body 10. Further, the deviation distance between the second lower hopper wall 22 and the second upper hopper wall 12 satisfies 2... The deviation distance between the second lower chamber wall 22 and the axis 111a of the toner filling hole 111 is increased to 52mm < L1 + L2 ≤ 75mm, which increases the width of the lower chamber body 20. In addition, the operating part 221 and the recessed part 222 provided in the second lower chamber wall 22 form a receiving cavity 30. The receiving cavity 30 reduces the overall weight of the toner hopper 100 and is easy to accommodate the hand. The hand is not interfered with and the operation is very easy. The upper chamber body 10 and the lower chamber body 20 of the toner hopper 100 have a large toner loading capacity, and there is no need to frequently disassemble the machine to add toner. The operation is time-saving and labor-saving, and the user experience is good.

[0035] In this embodiment, specifically, the deviation distance between the first upper chamber wall 11 and the center line 10a of the upper chamber body 10 satisfies 200mm < L3 ≤ 250mm; that is, the deviation distance between the first upper chamber wall 11 with powder filling hole 111 and the center line 10a of the upper chamber body 10 is increased to 200mm < L3 ≤ 250mm, which increases the length of the upper chamber body 10.

[0036] Furthermore, in this embodiment, the deviation distance between the third upper chamber wall 13 and the axis 111a of the powder filling hole 111 satisfies 20mm < L4 ≤ 30mm; as set above, the height of the upper chamber 10 is increased, and the toner loading capacity of the upper chamber 10 is further increased.

[0037] In this embodiment, the deviation distance between the first lower compartment wall 21 and the first upper compartment wall 11 further satisfies 2mm < L5 ≤ 5mm. That is, the deviation distance between the first lower compartment wall 21 and the centerline 10a of the upper compartment body 10 is increased to 202mm < L3 + L5 ≤ 255mm, which increases the length of the lower compartment body 20 and further increases the toner loading capacity of the lower compartment body 20.

[0038] In this embodiment, the upper chamber 10 further includes a first connecting wall 14, and the lower chamber 20 further includes a second connecting wall 23. The first connecting wall 14 and the second connecting wall 23 are connected by a snap-fit, and then welded together. As configured above, a stable vertical connection between the upper chamber 10 and the lower chamber 20 can be achieved, preventing toner leakage.

[0039] Preferably, see Figure 2 The upper chamber 10 also includes an inclined wall 15. The upper end 15a of the inclined wall 15 is connected to the third upper chamber wall 13, the side end 15b is connected to the first upper chamber wall 11, and the lower end 15c is connected to the first connecting wall 14. The distance between the upper end 15a and the axis 111a of the toner filling hole 111 is the smallest, and the distance between the lower end 15c and the axis 111a of the toner filling hole 111 is the largest. With the inclined wall 15 configured as described above, when the developing device is installed, the inclined wall 15 limits the installation of the printer mounting cavity, preventing the upper chamber 10 from being over-installed and ensuring that the upper chamber 10 is installed in place.

[0040] Furthermore, the distance between the lower end 15c and the axis 111a of the toner filling hole 111 satisfies 60mm < L6 ≤ 80mm. As set above, the width of the upper chamber 10 is further increased, and the toner loading capacity of the upper chamber 10 is further increased.

[0041] See Figure 5 and Figure 6 In this embodiment, preferably, one end of the second upper chamber wall 12 is provided with a first positioning guide groove 121, which penetrates the third upper chamber wall 13. The first positioning guide groove 121 includes two groove walls that are substantially perpendicular to each other. The second lower chamber wall 22 is correspondingly provided with a second positioning guide groove 223, which penetrates the first positioning guide groove 121. When the developing device is installed, the above-mentioned positioning guide grooves cooperate with the positioning part of the printer mounting cavity, so that the toner cartridge 100 is installed stably and accurately, ensuring print quality.

[0042] Preferably, in this embodiment, the accommodating cavity 30 is elongated, and its long axis is parallel to the length direction of the upper chamber 10, which conforms to ergonomic design and facilitates stable accommodation of the hand. When assembling or disassembling the developing device, the hand-held operating part is easy to operate.

[0043] In addition, this embodiment also provides a developing device, which includes a waste toner hopper (not shown) and a toner hopper 100 as described above. The waste toner hopper and the toner hopper 100 are connected and assembled. The developing device is installed in a printing device to perform developing operations.

[0044] Finally, it should be noted that the above description is merely the preferred embodiment of this utility model and is not intended to limit the utility model in any way. Any person skilled in the art can make many possible changes and simple substitutions to the technical solution of this utility model using the disclosed methods and technical content without departing from the scope of the technical solution of this utility model, and these all fall within the protection scope of the technical solution of this utility model.
