Technical Field
[0001] This utility model relates to the field of toner cartridge technology, and in particular to a toner cartridge for laser printers. Background Technology
[0002] Modern office equipment includes electro-photographic imaging devices, such as laser printers and digital copiers. While the structures of these devices vary, their working principles are essentially the same. They all involve six processes: charging, exposure, development, transfer, fixing, and cleaning. In the transfer process of a laser printer, the toner is pushed by the stirring rack inside the toner cartridge and adsorbed by the developing roller. The toner is then transferred to the printing paper or other media. Finally, the fixing device heats and pressurizes the toner to melt it, which then solidifies into text and images on the paper.
[0003] Existing toner cartridges are inconvenient for staff to add toner during installation and use, have poor sealing, and the small parts are easy to lose during the toner addition process, affecting the use of the toner cartridge. They also have poor dehumidification effect, which brings certain adverse effects to the user experience. In order to overcome the shortcomings of the existing technology, we propose a toner cartridge for laser printers. Utility Model Content

[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. In this utility model, the handle facilitates the installation and disassembly of the toner cartridge and printer by the operator. The toner inlet facilitates the delivery of new toner into the toner hopper. The sealing cap and plug provide a double seal for the toner inlet, preventing the equipment from malfunctioning if the sealing cap is lost. The rubber stopper facilitates the sealing of the toner outlet and allows the operator to easily open the rubber stopper to empty the waste toner hopper when adding toner.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] Example 1, as Figures 1-7 As shown, a toner cartridge for a laser printer includes a toner cartridge 1. A handle 2 is provided on the outer surface of the front end of the toner cartridge 1, which facilitates the installation and removal of the toner cartridge 1 from the printer. When toner needs to be added, the toner cartridge 1 is removed, the sealing cap 7 is unscrewed, the toner bottle opening is tilted, the toner cartridge 1 is placed vertically, the toner bottle opening is inserted into the toner inlet 4, and the plug 29 is pressed downwards to separate it from the side of the toner storage compartment 3. At this time, there is a sufficient gap between the plug 29 and the toner inlet 4 for toner to enter the new toner compartment 11. The toner falls into the new toner compartment under the action of gravity. Inside the new toner cartridge 11, the toner bottle is then pulled out from the toner inlet 4 to complete the toner filling process. The upper surface of the plug 29 is tapped downwards with a round stick to shake the toner scattered on its surface into the new toner cartridge 11. Under the elastic force of the spring 30, the plug 29 is pushed upwards and locked inside the toner inlet 4. The second sealing ring 31 is used to seal the toner inlet 4 to prevent toner leakage. At the same time, the sealing cap 7 is tightened. The plug 29 can effectively provide double protection for the toner inlet 4, preventing the toner cartridge from being unusable due to the small size of the sealing cap 7 during toner filling.
[0025] Example 2, as Figures 1-7As shown, a toner cartridge for a laser printer allows for the following process: When the operator needs to clean the waste toner, the rubber stopper 8 is opened, the toner outlet 5 is turned downwards, and the toner cartridge 1 is shaken left and right. Waste toner is discharged outwards through the outlet 5 under gravity. A sealing plate 14 seals the new toner compartment 11 and the waste toner compartment 12. When the operator needs to perform a deep cleaning of the waste toner compartment 12, the sealing plate 14 is removed, and the waste toner inside the compartment is cleaned with a brush. During operation, the toner cartridge 1 periodically powers the motor 26 and heating wire 15, causing them to control the rotation of the main shaft 25 and the stirring blade 24, thus agitating the toner. To prevent clumping, the air inside the heating chamber 16 is heated by the heating wire 15, and the heat is transferred to the interior of the new powder chamber 11 by multiple sets of heat-conducting rods 19 to dry the toner. When the gas inside the new powder chamber 11 is heated, the air pressure increases. When the pressure increases to a certain level, it pushes the sealing plug 20 upward, creating a gap between it and the exhaust port 22. At this time, the hot air inside the new powder chamber 11 is transported outward until the pressure difference between the inside and outside of the new powder chamber 11 is equal. Under the action of the counterweight 21, the sealing plug 20 is controlled to descend, and the exhaust port 22 is sealed by the first sealing ring 23 to prevent waste powder leakage.
[0026] It should be noted that this utility model is a toner cartridge for a laser printer. In use, the handle 2 allows the operator to easily remove the toner cartridge 1 from the printer. The toner cartridge 1 is placed vertically, the sealing cap 7 is unscrewed, and the toner bottle opening is inserted into the toner inlet 4. The bottle is then pressed downwards to separate the plug 29 from the inlet 4, leaving sufficient clearance for toner to enter the new toner container 11. After toner filling, the toner bottle is pulled out of the inlet 4. The spring 30 pushes the plug 29 upwards, making it fit tightly against the inlet 4. The second sealing ring 31 seals the inlet 4. The sealing cap 7 is then tightened, providing a double seal for the inlet 4 through the plug 29 and the sealing cap 7. When the operator needs to clean the waste toner, the toner cartridge 1 is placed horizontally with the outlet 5 facing downwards. The rubber stopper 8 is opened, and the toner cartridge 1 is shaken horizontally from side to side. Under gravity, the waste toner falls from the waste toner container 12. The sealing plate 14 above the waste toner hopper 12 is removed, and the inner wall of the waste toner hopper 12 is thoroughly cleaned using a cleaning brush. After completion, the sealing plate 14 is fixed above the waste toner hopper 12, sealing the new toner hopper 11 and the waste toner hopper 12. The heating wire 15 and the motor 26 are periodically energized, and the heating wire 15 heats the air inside the heating chamber 16. Multiple sets of heat-conducting rods 19 transfer the heat to the interior of the new toner hopper 11, thus heating the toner. During drying, the stirring blades 24 are rotated by the motor 26 to agitate the toner and prevent it from clumping. When the gas inside the new toner hopper 11 is heated and the gas pressure increases, the sealing plug 20 is pushed upward to create a sufficient gap between the sealing plug 20 and the exhaust port 22, allowing the hot air inside the new toner hopper 11 to be discharged to the outside. When the pressure difference between the inside and outside of the new toner hopper 11 is consistent, the sealing plug 20 is pressed tightly against the exhaust port 22 under the gravity of the counterweight 21, thus sealing the new toner hopper 11.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
