Technical Field

[0001] This utility model relates to the field of toner cartridge technology, and in particular to a quick-release toner cartridge. Background Technology

[0002] With the rapid development of society, printers are increasingly used in offices. In laser printers, more than 70% of the imaging components are concentrated in the toner cartridge. The quality of printing is largely determined by the toner cartridge. The toner cartridge not only determines the quality of printing, but also the amount of money the user needs to spend during use. Existing toner cartridges are not convenient for quick disassembly and installation during the assembly and disassembly of the device, resulting in low repair efficiency. This utility model proposes a new solution to the above problems. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0022] like Figures 1 to 6 The quick-release toner cartridge shown is characterized by comprising: a toner cartridge body 1, a toner filling hole 11 connected to the rear right side of the toner cartridge body 1, a sealing cover 12 on the toner filling hole 11, a toner storage space 2 inside the toner cartridge body 1, a discharge port 3 on one side of the toner cartridge body 1 and connected to the toner storage space 2, a developing roller 4 and an imaging drum 5 respectively movably sleeved in the discharge port 3, a connecting housing 6 on the toner cartridge body 1, a transmission assembly 7 on the left side of the toner cartridge body 1, a fixing part 8 above the toner cartridge body 1 that can fix the connecting housing 6 and the toner cartridge body 1 to each other, and a mounting part 9 on the connecting housing 6 that can be installed in a printing device.

[0023] In this quick-install toner cartridge with the above structure, the user places the toner cartridge body 1 inside the printer and aligns it with the drive output. The mounting part 9 then supports and fixes the toner cartridge body 1 inside the printer. When the toner cartridge body 1 needs to be refilled or repaired, the user unlocks the fixing part 8, causing the connecting housing 6 and the toner cartridge body 1 to separate. At this time, the user can deliver toner to the toner storage space 2 or repair the toner cartridge body 1. During operation, the developing roller 4 and the imaging drum 5 can be driven by the transmission component 7. Compared with the existing technology, this design facilitates quick disassembly and installation of the toner cartridge and improves repair efficiency.

[0024] like Figure 3As shown, in some embodiments of this utility model, the connecting housing 6 includes a left housing 61 and a right housing 62 respectively disposed on the left and right sides of the toner cartridge body 1. The left housing 61 and the right housing 62 are provided with connecting parts 63 that can be connected to each other, and a connecting hole 611 is provided on the left side of the left housing 61.

[0025] like Figure 4 As shown, in some embodiments of this utility model, the transmission assembly 7 includes a drive wheel 71 and an idler wheel 72 connected to each other on the left side of the drum body 1. The drive wheel 71 and the idler wheel 72 are fixedly connected to the imaging drum 5 and the developing roller 4, respectively. The drive wheel 71 and the idler wheel 72 are flexibly fitted together. A connecting wheel 73 and a stirring wheel 74 are sequentially fitted to the rear side of the idler wheel 72. Driven by the printer, the drive unit inside drives the drive wheel 71 to rotate through the connecting hole 611. While the drive wheel 71 rotates, it drives the idler wheel 72 to rotate, thereby driving the imaging drum 5 and the developing roller 4. The connecting wheel 73 can drive the stirring wheel 74 to rotate. The user can install a stirring roller on the stirring wheel 74 as needed to agitate the toner in the toner storage space 2.

[0026] like Figure 3 As shown, in some embodiments of this utility model, the fixing part 8 includes symmetrically fixed insertion slots 81 on the top of the drum body 1. An opening 82 is provided above each insertion slot 81. A retaining plate 83 is symmetrically inserted into each insertion slot 81. A handle 84 that can be disposed in the opening 82 is fixed on one side of each retaining plate 83. Multiple springs 85 are connected between every two handles 84. A chamfer 86 is provided on each retaining plate 83. Engaging grooves 87 are provided on both the left housing 61 and the right housing 62. The user can then... The left housing 61 and the right housing 62 move upwards towards the drum body 1, causing the engaging grooves 87 on the left housing 61 and the right housing 62 to contact the chamfer 86 on the card plate 83. At this time, the chamfer 86 drives the card plate 83 to move along the insertion groove 81. After the engaging groove 87 passes the card plate 83, the spring 85 drives each card plate 83 to reset, so that the card plate 83 is locked in the engaging groove 87. When it is necessary to disassemble the left housing 61 and the right housing 62, the user pulls the handle 84, causing the handle 84 card plate 83 to move, and the card plate 83 and the engaging groove 87 are separated.

[0027] like Figure 2 and 5As shown, in some embodiments of this utility model, the mounting part 9 includes a plug-in sleeve 91 disposed on one side of the left housing 61 and the right housing 62. A sliding sleeve 92 is movably inserted into each plug-in sleeve 91. An anti-slip plate 93 is fixed at the end of each sliding sleeve 92. A boss 94 is provided in each plug-in sleeve 91. A spring spring 95 is connected between each boss 94 and an adjacent plug-in sleeve 91. A slide rail 96 is provided through one side of each plug-in sleeve 91. A slider 97 is movably inserted into each slide rail 96. A screw hole 98 is provided in the middle of each slider 97. A screw 99 is threaded into each screw hole 98. A screw 99 is fixed at both ends of each screw 99. The printer has a knob 910 and a top plate 911. When the user places the toner cartridge body 1 inside the printer, the spring spring 95 connected between the boss 94 and the adjacent plug sleeve 91 drives the sliding sleeve 92 to move towards the wall inside the printer, so that the anti-slip plate 93 supports the toner cartridge body 1 against the wall inside the printer. Then, by rotating the knob 910, the knob 910 drives the screw 99 to rotate in the screw hole 98. At this time, the screw 99 drives the top plate 911 to press against the plug sleeve 91, so that the sliding sleeve 92 and the plug sleeve 91 are fixed to each other. When rotating the screw 99, the position of the slider 97 in the slide rail 96 can be adjusted so that the position of the top plate 911 pressing against the plug sleeve 91 is adjusted to a suitable position.

[0028] like Figure 6 As shown, in some embodiments of this utility model, the connecting part 63 includes buckles 631 symmetrically fixed on the front and rear sides of the left housing 61, and slots 632 symmetrically fixed on the front and rear sides of the right housing 62. A push plate 633 is movably inserted into each slot 632. An inclined block 634 is fixed on the opposite side of each pair of buckles 631. Each buckle 631 and each push plate 633 is provided with a locking point 635 and a locking groove 636. After the left housing 61 and the right housing 62 are installed above the toner cartridge body 1, the buckles 631 are placed in the slots 632. At this time, the user pulls the push plate 633, causing the push plate 633 to disengage from the inclined block 634. At this time, the inclined block 634 causes the buckles 631 to deform until the protrusion on the buckle 631 engages with the recess in the slot 632. At the same time, the locking groove 636 on the push plate 633 engages with the locking point 635.
