Description

Technical Field

[0001] This utility model relates to the technical field of toner cartridges, and in particular to an easy-to-refill toner cartridge. Background Technology

[0002] Toner cartridges are the core consumable component in printers used to store toner. During printing, they distribute the toner evenly onto the paper to form text or images. Currently, once the toner is depleted, the cartridge is a disposable product and cannot be reused, requiring replacement with a new cartridge, resulting in high costs. Secondly, the toner inside the cartridge is dispensed via a piston-driven mechanism. However, during this process, toner tends to remain on the inner wall of the cartridge, leading to a significant amount of residual toner and reducing the toner supply. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a toner cartridge that can be recycled and reduces the amount of residual toner.

[0004] The technical solution adopted by this utility model is as follows: This utility model includes a box body, on which a powder inlet, a powder outlet, and a driving mechanism are provided. A powder storage cavity is provided in the box body. The powder inlet and the powder outlet are both connected to the powder storage cavity. A stirring frame is provided in the powder storage cavity. The stirring frame includes a mounting bracket and multiple arc-shaped stirring blades. The driving mechanism can drive the mounting bracket to rotate. The multiple arc-shaped stirring blades are staggered on the mounting bracket and all abut against the inner wall of the powder storage cavity.

[0005] Furthermore, the housing is provided with a sensor port that communicates with the toner storage chamber, and the sensor port is used to detect the remaining toner in the toner storage chamber.

[0006] Furthermore, the driving mechanism includes a driving gear, the driving gear is axially connected to a transmission shaft, one end of the powder storage chamber is provided with a connecting hole, the end of the transmission shaft passes through the connecting hole and is connected to the mounting bracket, a sealing ring is sleeved on the transmission shaft, and the outside of the sealing ring abuts against the connecting hole.

[0007] Furthermore, the drive shaft has an annular groove, and the sealing ring is fitted into the annular groove.

[0008] Furthermore, one end of the mounting bracket is provided with a connecting groove, and a slot is provided on the connecting groove. The end of the drive shaft is connected to the connecting groove and engaged with the slot. The other end of the mounting bracket is rotatably connected to the powder storage cavity.

[0009] Furthermore, the mounting bracket is provided with a powder feeding plate, which is configured to correspond to the powder outlet.

[0010] Furthermore, all of the arc-shaped stirring blades are arranged at an angle, with the ends of the arc-shaped stirring blades close to the ends of the adjacent arc-shaped stirring blades.

[0011] Furthermore, a powder filling cap is detachably connected to the powder filling port, and the powder filling port is located at the end of the box body.

[0012] Furthermore, one end of the box has a first cover and the other end has a second cover. The powder filling port is located on the first cover, and the drive gear is located in the second cover. The second cover has an opening corresponding to the drive gear.

[0027] like Figures 1 to 4As shown, in this embodiment, the present invention includes a box body 1, on which a powder inlet 2, a powder outlet 3, and a driving mechanism 5 are provided. A powder storage chamber 6 is provided in the box body 1. The powder inlet 2 and the powder outlet 3 are both connected to the powder storage chamber 6. A stirring rack 7 is provided in the powder storage chamber 6. The stirring rack 7 includes a mounting bracket 8 and multiple arc-shaped stirring blades 9. The driving mechanism 5 can drive the mounting bracket 8 to rotate. The multiple arc-shaped stirring blades 9 are staggered on the mounting bracket 8 and all abut against the inner wall of the powder storage chamber 6.

[0028] Compared with the shortcomings of the prior art, in this utility model, when the toner in the toner storage chamber 6 is exhausted, toner can be easily replenished into the toner storage chamber 6 through the toner filling port 2, so that the toner box can be recycled. In addition, the toner in the toner storage chamber 6 is stirred and transported by multiple arc-shaped stirring blades 9, so that the toner in the toner storage chamber 6 can be pushed to the toner outlet 3 for discharge by the arc-shaped stirring blades 9. In particular, since the multiple arc-shaped stirring blades 9 are staggered on the mounting bracket 8 and all abut against the inner wall of the toner storage chamber 6, the multiple arc-shaped stirring blades 9 can effectively scrape the inner wall of the toner storage chamber 6 and can repeatedly scrape off the toner on the inner wall of the toner storage chamber 6 to reduce the residual amount of toner. Therefore, this utility model has the advantages of being recyclable and reducing the residual amount of toner.

[0029] In some embodiments, the cartridge 1 is provided with a sensing port 12 communicating with the toner storage chamber 6. The sensing port 12 is used to detect the remaining toner level in the toner storage chamber 6. Specifically, after the toner cartridge is installed in the printer, the printer's detection unit detects the remaining toner level in the toner storage chamber 6 through the sensing port 12 to promptly remind the user when the toner in the cartridge is depleted. The detection unit can be a sensor device for sensing the remaining toner level, such as a photoelectric sensor detection device, which detects the remaining toner level through the principle of optical reflection, specifically including a light emission path and a light reception path. When the toner is replenished, the light is absorbed, causing the signal at the receiving end to weaken; when the toner level decreases, the reflected light strengthens, and the sensor determines the remaining level by detecting the change in light intensity. Alternatively, the detection unit can be a non-contact optical detection module for sensing the remaining toner level, which projects light onto the inner wall of the toner storage chamber 6 through the sensing port 12 and calculates the remaining level by utilizing the change in the absorption characteristics of toner for a specific wavelength of light.

[0030] In some embodiments, the drive mechanism 5 includes a drive gear 13, with a transmission shaft 15 axially connected to the drive gear 13. One end of the toner storage chamber 6 has a connecting hole 16, and the end of the transmission shaft 15 passes through the connecting hole 16 and is connected to the mounting bracket 8. A sealing ring 17 is fitted onto the transmission shaft 15, with the outer side of the sealing ring 17 abutting against the connecting hole 16. An annular groove 18 is formed on the transmission shaft 15, and the sealing ring 17 is fitted into the annular groove 18. After the toner cartridge is installed, the printer drives the drive gear 13, causing the transmission shaft 15 to rotate, thus enabling the arc-shaped stirring blades 9 to stir and transport the toner in the toner storage chamber 6. Specifically, the existing technology uses sealing cotton to achieve the seal between the drive shaft 15 and the connecting hole 16. However, the sealing cotton may loosen during long-term use, resulting in poor sealing effect. Therefore, by setting a sealing ring 17 that abuts against the connecting hole 16 on the drive shaft 15, not only can the carbon powder in the powder storage chamber 6 be prevented from flowing out to the outside through the connecting hole 16, but it can also have a better sealing effect during long-term use.

[0031] In some embodiments, one end of the mounting bracket 8 is provided with a connecting groove 19, and a retaining groove 20 is provided on the connecting groove 19. The end of the drive shaft 15 is connected to the connecting groove 19 and engaged with the retaining groove 20. The other end of the mounting bracket 8 is rotatably connected to the powder storage chamber 6. A powder-feeding plate 21 is provided on the mounting bracket 8, and the powder-feeding plate 21 is correspondingly provided with the powder outlet 3. Specifically, by connecting the end of the drive shaft 15 to the connecting groove 19 and engaging with the retaining groove 20, the stability of the drive shaft 15 when connected to the mounting bracket 8 can be ensured. In addition, when the stirring rack 7 rotates, the powder-feeding plate 21 can concentrate the toner at the powder outlet 3, ensuring a sufficient powder feeding amount.

[0032] In some embodiments, the plurality of arc-shaped stirring blades 9 are all inclined, with the ends of the arc-shaped stirring blades 9 close to the ends of adjacent arc-shaped stirring blades 9. Specifically, through the above arrangement, the plurality of arc-shaped stirring blades 9 can effectively scrape off the toner from the inner wall of the toner storage chamber 6, thereby further reducing the amount of toner residue on the inner wall of the toner storage chamber 6.

[0033] In some embodiments, a toner filling port 2 is detachably connected to a toner filling cover 22, and the toner filling port 2 is located at the end of the cartridge body 1; one end of the cartridge body 1 has a first cover 23, and the other end has a second cover 25, the toner filling port 2 is located on the first cover 23, and the drive gear 13 is located in the second cover 25, the second cover 25 is provided with an opening 26 corresponding to the drive gear 13. Specifically, toner is added through the toner filling port 2 by removing the toner filling cover 22; in addition, the opening 26 is used to expose the drive gear 13; after installation, the printer drives the drive gear 13 at the opening 26, so that the mixing rack 7 can rotate.

[0034] In some embodiments, the toner storage chamber 6 can hold 350g to 400g of toner. Specifically, the toner storage chamber 6 has a large capacity, which can increase the amount of toner loaded.

[0035] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
