Description

Technical Field

[0001] This utility model relates to the field of printer consumables technology, specifically to a printer toner cartridge that is easy to refill. Background Technology

[0002] Printer toner cartridges are the core consumables in laser printers responsible for image formation. They typically contain key components such as a toner container, waste toner container, photosensitive drum, and developing roller. Text or images are printed through the electrostatic attraction and transfer of toner. To reduce operating costs, users often refill the toner cartridge after it runs out by removing the end cover and opening the refill port. Therefore, the ease and stability of the refilling process are crucial factors affecting the usability of the toner cartridge.

[0003] Existing toner cartridge end caps are typically fixed to the drum body with multiple screws, requiring users to have specialized tools such as screwdrivers to disassemble them. This not only increases the operational threshold but also makes the process of tightening multiple screws time-consuming and laborious, especially for non-professional users, who are prone to stripping screws or damaging the end cap due to improper operation. In addition, during toner refilling, toner is prone to clumping due to changes in the humidity of the storage environment or long-term stagnation. When the refill nozzle is inserted into the refill port, the clumped toner will block the channel, preventing toner from smoothly entering the toner cartridge. Users often need to repeatedly tap the drum body at the refill port to clear the channel, which not only easily causes toner spillage and contamination but may also damage the photosensitive components inside the toner cartridge due to vibration, affecting print quality. Therefore, a printer toner cartridge that is easy to refill is proposed. Utility Model Content

[0033] In one embodiment, specifically: limiting posts 34 are fixedly connected to both sides of the front portion of the upper surface of the drum body 11, and limiting holes 35 are opened on both sides of the front portion of the lower surface of the upper end cover 13. The upper part of the outer side wall of the limiting post 34 is attached to the inner side wall of the limiting hole 35. The cooperation between the limiting post 34 and the limiting hole 35 can ensure the accurate positioning of the upper end cover 13 during installation. At the same time, after the upper end cover 13 is installed, it plays a supporting and fixing role for the upper end cover 13.

[0034] In one embodiment, specifically: the bottom of the drum body 11 is fixedly connected to a lower end cover 37 by a plurality of screws 36; wherein, the lower end cover 37 is used to seal the bottom components of the drum body 11 (such as waste toner hopper or transmission structure), and does not need to be disassembled during toner filling operation, but is only disassembled by unscrewing the screws 36 during deep maintenance.

[0035] Working principle or structural principle

[0036] When the toner in the drum is depleted and needs to be refilled, the top cover 13 must first be removed. The specific steps are as follows:

[0037] The user inserts their fingers into the disassembly groove 14, pinches the lever 38 on the upper surface of the two sliders 16, and pushes them towards the center. This causes the sliders 16 to slide along the inner side of the slide groove 15. The sliders 16 drive the pins 17 to move inward simultaneously, compressing the spring 21 between the first mounting groove 20 and the second mounting groove 22. At the same time, the end of the pin 17 away from the slider 16 exits from the pin hole 19 of the insert 12, releasing the fixed relationship between the upper cover 13 and the toner cartridge body 11. The user then pulls the upper cover 13 upward to detach it from the fitting connection of the insert 12. At this time, the limiting hole 35 on the lower surface of the upper cover 13 separates from the limiting post 34 on the toner cartridge body 11, completing the disassembly.

[0038] After the upper cover 13 is removed, the powder filling operation begins. The specific process is as follows:

[0039] The user pulls the outer sealing cap 31 inside the toner tube 23 upwards by pulling the ear loop 32. At this time, the annular sealing ring 33 on the upper part of the toner tube 23 is temporarily separated from the outer sealing cap 31 (it can be resealed when closed later to prevent toner leakage); insert the toner nozzle of the external toner bottle into the cross-shaped membrane hole 39 of the inner sealing cap 30; connect an external power source (such as a power bank or mobile phone charger) through the Type-C interface 27, start the vibration motor 26 in the annular vibrator 24, the vibration motor 26 drives the annular vibrator 24 to vibrate at high frequency and transmit it to the toner tube 23, so that the clumps of toner in the tube and toner compartment are broken up to avoid clogging the toner filling channel; slowly pour the toner, and the toner flows smoothly into the toner compartment of the drum body 11 through the cross-shaped membrane hole 39 under the action of vibration;

[0040] After toner filling is completed, pull out the nozzle, and the cross-shaped membrane hole 39 automatically springs back to seal. Press the outer sealing cap 31 down along the inner wall of the toner filling tube 23 until its outer wall is tightly fitted with the annular sealing ring 33 to achieve a secondary seal. The double sealing structure prevents the toner from getting damp or leaking. Align the position of the upper end cap 13 with the drum body 11, so that the limiting pin 34 is inserted into the limiting hole 35 of the upper end cap 13, and the insert block 12 is fitted with the inner wall of the upper end cap 13. Release the lever 38, the spring 21 releases its stored energy, pushes the slider 16 to reset along the slide groove 15 to the outside, and drives the pin 17 to re-insert into the pin hole 19 of the insert block 12 to complete the fixing of the upper end cap 13.

[0041] In summary, this utility model, through the quick-release structure composed of slider 16, pin 17, spring 21, etc., and in conjunction with the operation of the lever 38, allows for the quick disassembly and installation of the upper cover 13 without the need for tools such as screwdrivers. This avoids the risk of stripped screws or damage to the upper cover 13, lowers the operational threshold, and improves operational convenience. Through the annular vibrator 24 and vibration motor 26 on the outside of the powder filling tube 23, vibration can be generated during powder filling to break up clumps of toner, eliminating the need for manual tapping and preventing toner spillage and contamination. At the same time, the annular structure of the annular vibrator 24 can evenly transmit vibration force, avoiding excessive local vibration that could damage the internal photosensitive components.
