Description

Technical Field

[0001] This utility model relates to office equipment, and in particular to a toner cartridge that is easy to replace toner, belonging to the field of printer consumables technology. Background Technology

[0002] Toner cartridges are a core consumable for enabling printing functions in office equipment such as printers and copiers. The ease of toner replacement is closely related to the efficiency of office scenarios. In daily office work, printers are used extremely frequently, and once the toner runs out, it needs to be replaced promptly to ensure the continuous operation of document printing and data output.

[0003] Publication number CN220626863U discloses a universal toner cartridge, including a main body and a fixing mechanism. The fixing mechanism is located on the left and right sides of the main body. The main body includes a toner cartridge body, a toner storage compartment, and a partition. The toner storage compartment is fixedly installed at the inner end of the toner cartridge body, and the partition is fixedly installed at the right end of the toner storage compartment. The main body also includes a recycling compartment and an anti-condensation component. The recycling compartment is fixedly installed at the inner end of the toner cartridge body and the right end of the partition. The anti-condensation component is fixedly installed at the left end of the toner storage compartment, and a vibration motor is fixedly installed at the inner end of the toner cartridge body. This universal toner cartridge, by installing the anti-condensation component, allows the device to re-break up condensed toner through vibration, thereby reducing the impact of condensed toner on printer printing efficiency and improving the device's working efficiency.

[0004] However, in actual toner replacement operations, these toner cartridges are usually paired with toner bottles or refill bottles for refilling. These bottles, with their slender, pointed nozzles designed for precise alignment with the toner cartridge's refill port, still have some areas for improvement. The length and thickness of the nozzle often don't perfectly match the toner cartridge's refill port, potentially leading to toner leakage. When squeezing the bottle to add toner, if the refill port is too large, a gap may form between the nozzle and the port, allowing some toner to spray out or spill. This not only causes unnecessary toner waste but also pollutes the surrounding environment and may even pose a potential health risk if the toner is inhaled while floating in the air. These issues require improvement.

[0005] Therefore, a toner cartridge that facilitates toner replacement is proposed. Utility Model Content

[0006] In view of this, the present invention provides a toner cartridge that facilitates toner replacement, so as to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial alternative.

[0007] The technical solution of this utility model is implemented as follows: A toner cartridge that facilitates toner replacement includes a mounting base and a toner cartridge body.

[0015] I. In this utility model, by setting a closing mechanism at the feed inlet of the toner cartridge, when adding toner with a toner bottle or refill bottle, the closing mechanism automatically squeezes and tightly seals the closing sleeve against the nozzle of the toner bottle. This fundamentally eliminates the gap between the nozzle and the feed inlet, completely preventing toner leakage or spillage. Simply moving the lever opens the closing mechanism, facilitating nozzle insertion; releasing the lever automatically tightens the closing sleeve to seal the nozzle, achieving a seal without additional operation. Furthermore, the entire process requires no specialized tools, improving toner filling efficiency while reducing toner waste and environmental pollution, making it highly practical.

[0016] Second, in this utility model, by setting a quick connection mechanism between the toner cartridge and the mounting base, the disassembly and assembly process when replacing toner is effectively simplified. When toner needs to be replaced, the toner cartridge can be quickly removed from the mounting base. Compared with the cumbersome method of traditional bolt connection that requires repeated tightening with tools, this design can release the limit with just a pull, making disassembly efficient and labor-saving. During installation, simply align the cartridge with the mounting base and push it to achieve automatic positioning and fixation, without the need for additional tools.

[0026] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] like Figure 1-6 As shown, this utility model embodiment provides a toner cartridge that facilitates toner replacement, including a mounting base 1 and a toner cartridge body 2. A fixing ring plate 5 is installed on the toner cartridge body 2, a rotating plate 3 is rotatably installed inside the toner cartridge body 2, a guide groove 4 is provided on the rotating plate 3, a frame plate 6 is installed inside the fixing ring plate 5, a lever 7 is installed below the rotating plate 3, a moving block 8 is slidably installed inside the frame plate 6, a top block 9 is installed above the moving block 8, a guide rod 10 is installed below the moving block 8, an arc-shaped groove 11 is provided on the toner cartridge body 2, a coil spring 12 is installed inside the toner cartridge body 2, and a closing leather sleeve 13 is fitted above the top block 9.

[0029] In one embodiment, the guide rod 10 is disposed in the guide groove 4, and the toggle block 7 is slidably disposed in the arc groove 11. During the rotation of the rotating plate 3, the guide groove 4 on its surface will generate relative movement with the guide rod 10 below the moving block 8. Under the action of the guide groove 4, the guide rod 10 will drive the moving block 8 to slide within the frame plate 6.

[0030] In one embodiment, the toner cartridge 2 is provided with a feed inlet, the fixing ring plate 5 is located above the feed inlet, and the closing sleeve 13 is made of rubber. The closing sleeve 13 fitted on the top block 9 will open as the top block 9 separates, thereby facilitating the insertion of the toner bottle's nozzle into the feed inlet.

[0031] In one embodiment, one end of the coil spring 12 is installed inside the toner cartridge 2, and the other end of the coil spring 12 is installed below the rotating plate 3. When the lever 7 is released, the coil spring 12 inside the toner cartridge 2 releases its elastic force, causing the rotating plate 3 to rotate in the opposite direction to reset.

[0032] In one embodiment, a connecting frame 14 is installed on the back of the toner cartridge 2, and an insert plate 15 is slidably installed inside the connecting frame 14. A magnet A16 is provided at one end of the insert plate 15. A cavity plate 17 is installed inside the mounting base 1, and a tongue-shaped block 18 is slidably installed inside the cavity plate 17. A pull rod 20 is installed on the side of the tongue-shaped block 18, and a spring 19 is sleeved on the pull rod 20. A slot plate 21 is also installed inside the mounting base 1, and a magnet B22 is provided inside the tongue-shaped block 18. When the toner needs to be replaced, the toner cartridge 2 can be quickly removed from the mounting base 1. Compared with the cumbersome method of traditional bolt connection that requires repeated tightening with tools, this design can be released with just a gentle pull.

[0033] In one embodiment, one end of the spring 19 is installed inside the cavity plate 17, and the other end of the spring 19 is installed on the side of the tongue block 18. The spring 19 drives the tongue block 18 to tend to insert into the connecting frame 14. When the insert plate 15 coincides with the position of the tongue block 18, the tongue block 18 will move towards the connecting frame 14 under the pushing force of the spring 19, and finally insert into the connecting frame 14.

[0034] In one embodiment, magnet A16 and magnet B22 are attracted by a magnetic field, and a handle is provided at one end of the pull rod 20 that passes through the outer wall of the cavity plate 17. When the pull rod 20 drives the tongue block 18 to slide into the cavity plate 17, the magnetic attraction between magnet A16 and magnet B22 will cause the insert plate 15 to return to the connecting frame 14.

[0035] In operation, when toner needs to be added to the toner cartridge 2, the toggle block 7 is first moved, causing it to slide along the arc-shaped groove 11 and rotate the rotating plate 3 within the toner cartridge 2. During the rotation of the rotating plate 3, the guide groove 4 on its surface will move relative to the guide rod 10 below the moving block 8. Under the action of the guide groove 4, the guide rod 10 will cause the moving block 8 to slide within the frame plate 6, causing the top blocks 9 above the multiple sets of moving blocks 8 to move away from each other. At this time, the sealing sleeve 13 fitted on the top block 9 will open as the top block 9 separates, making it easier for the tip of the toner bottle to be inserted into the feed inlet. Then, the lever 7 is released, and the coil spring 12 inside the toner cartridge 2 will release its elasticity, causing the rotating plate 3 to rotate in the opposite direction and reset. During the reset process of the rotating plate 3, the guide groove 4 drives the moving block 8 to reset again through the guide rod 10, so that multiple sets of top blocks 9 come closer to each other, and the sealing sleeve 13 tightens accordingly. After tightening, it will fit tightly against the tip of the toner bottle, thereby eliminating the gap between the tip and the feed inlet and effectively preventing toner leakage or spillage during toner addition.

[0036] When toner cartridge 2 needs to be installed onto mounting base 1, simply align the connecting frame 14 on the back of toner cartridge 2 with mounting base 1 and push it in. During the pushing process, the connecting frame 14 will first contact the tongue block 18. In this process, under the action of pressure and the tongue arc surface, the tongue block 18 will retract into the cavity plate 17 and cause the spring 19 to deform. When the insert plate 15 coincides with the tongue block 18, the tongue block 18 will move towards the connecting frame 14 under the pushing force of the spring 19 and finally insert into the connecting frame 14. At the same time, it will push the insert plate 15 and insert its other end into the slot plate 21. This completes the installation and fixation of the toner cartridge 2. When it is necessary to disassemble the toner cartridge 2, pull the handle at the end of the lever 20. The lever 20 will drive the tongue block 18 to slide into the cavity plate 17, so that the tongue block 18 exits the connecting frame 14. At this time, under the magnetic attraction of the magnetic field of magnet A16 and magnet B22, the insert plate 15 will be driven to return to the connecting frame 14, and one end of it will be pulled out from the slot plate 21, thereby releasing the limiting effect and allowing the toner cartridge 2 to be directly pulled out from the mounting base 1.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
