Description
Technical Field
[0001] The utility model relates to a split-type drum powder box, which specifically belongs to the technical field of printer equipment. Background Art
[0002] The laser printer in the prior art includes a main body and a separate drum toner cartridge that can be separated from the main body. A paper counter and a counter switch are installed on the main body, and the counter counts the number of sheets of paper that have been printed by the separate drum toner cartridge. Fig.10 , Fig.11 As shown, the split toner cartridge includes a cartridge body and a shell. The main body is provided with a master and slave wheel, a transmission wheel, and a reset gear. The reset gear is a sector wheel body, and the circumferential part of the sector wheel body has teeth. The reset gear is located in the shell. When a brand new toner cartridge filled with toner is installed on the host, the reset gear contacts the counter switch, so that the counter is powered and the counter is reset. After the counter is reset, the reset gear is driven by the transmission wheel. Since only a part of the circumference of the reset gear has teeth, that is, after the reset gear is driven to rotate a certain angle, the reset gear will not be driven by the transmission wheel, that is, the reset gear completes the task of resetting the counter. The counter has a default print quantity standard value for the number of sheets that can be printed by a new toner cartridge. When the toner in the split toner cartridge is almost consumed and the counter is about to reach the default print quantity standard value, a new toner cartridge should be replaced. In order to protect the environment and save consumables, people often want to reuse the split toner cartridges that can still be used. In this case, it is necessary to add toner to the old split toner cartridge, remove the side cover, and re-rotate and adjust the position of the reset gear to reset the reset gear so that the position of the reset gear in the old split toner cartridge is the same as the reset gear position in the new toner cartridge. It can be seen that the operation method of reusing the toner cartridge is relatively complicated, and special tools are needed to remove the side cover, which requires certain special technical means and is not conducive to the operation of ordinary people.

[0028] The present invention will be described in detail below in conjunction with specific embodiments.
[0029] Example 1: Figures 1 to 9 As shown, a split-type toner cartridge that can be easily reset includes a frame 100 and an outer shell. Of course, like a conventional toner cartridge structure, it has components such as a photosensitive drum, a cleaning scraper, a charging roller, etc. The outer shell includes a main shell 1 and a side cover 2. The frame 100 is located in the main shell. One end of the frame is equipped with a main driven wheel 3, a transmission wheel 4, and a reset gear 5. The main driven wheel 3, the transmission wheel 4, and the reset gear 5 are located in the side cover 2. The side cover 2 is connected to the end of the frame 100. The reset gear 5 is a fan-shaped wheel body, and the circumferential portion of the fan-shaped wheel body has teeth. The main driven wheel 3 is meshed with the main wheel 41 of the transmission wheel 4, and the secondary wheel 42 of the transmission wheel 4 is meshed with the reset gear 5. The side cover 2 is provided with a through hole 6 at a position corresponding to the position of the reset gear 5. The reset gear 5 is connected to a rotating handle 7, and the rotating handle 7 is exposed outside the side cover 2.
[0030] The side cover 2 is provided with a reset mark 8 near the through hole.
[0031] Working principle: Figure 5 , Figure 6The figure shows the state of the reset gear in the original position. At this time, it is the state of a brand new toner cartridge. After such a toner cartridge is installed in the main unit of the printer, the reset gear contacts the counter switch. When the printer is working, the counter is powered and reset. The counter has a default standard value for the number of sheets that can be printed by a new toner cartridge. After the counter is reset, the main and driven wheels drive the transmission wheel to rotate, and the reset gear is driven by the transmission wheel. Since only a part of the circumference of the reset gear has teeth (the reset gear is a sector wheel body), that is, after the reset gear is driven to rotate a certain angle, the reset gear will not be driven by the transmission wheel, that is, the reset gear has completed the task of resetting the counter and will no longer rotate.
[0032] When the toner in the split toner cartridge is almost consumed, Figure 7 , Figure 8 As shown, the reset gear is in this state. The counter is about to reach the default standard value of the number of prints, and a new toner cartridge must be replaced at this time. In order to protect the environment and save consumables, people often hope to reuse the split toner cartridge that can still be used. At this time, it is necessary to add toner to the old split toner cartridge, and then rotate the rotating handle to adjust the position of the reset gear back to the original position to reset the reset gear. After the operation, it is equivalent to a brand new toner cartridge, which can be installed on the main unit of the printer for use. The utility model is easy to operate, does not need to disassemble the side cover, does not require special tools, does not require special skills, and has low operating requirements. The toner cartridge can be quickly reused, which is beneficial to environmental protection.
[0033] Embodiment 2: The feature of this embodiment is that the reset gear is integrally formed with the rotating handle. The length of the rotating handle is smaller than the diameter of the through hole. This makes it more convenient to assemble and install the side cover, and the rotating handle can directly pass through the through hole. The rest is the same as embodiment 1.
[0034] Embodiment 3: A split toner cartridge that can be easily reset includes a frame 100 and an outer shell. Of course, like a conventional toner cartridge structure, it has components such as a photosensitive drum, a cleaning scraper, a charging roller, etc. The outer shell includes a main shell 1 and a side cover 2. The frame 100 is located in the main shell. One end of the frame is equipped with a main driven wheel 3, a transmission wheel 4, and a reset gear 5. The main driven wheel 3, the transmission wheel 4, and the reset gear 5 are located in the side cover 2. The side cover 2 is connected to the end of the frame 100. The reset gear 5 is a fan-shaped wheel body, and the circumferential portion of the fan-shaped wheel body has teeth. The main driven wheel 3 is meshed with the main wheel of the transmission wheel 4, and the secondary wheel of the transmission wheel 4 is meshed with the reset gear 5. The side cover 2 is provided with a through hole 6 at a position corresponding to the position of the reset gear 5. The reset gear 5 is connected to a rotating handle 7, and the rotating handle 7 is exposed outside the side cover 2.
[0035] The reset gear 5 has a connecting shaft extending from its axis toward the through hole 6 , and a free end of the connecting shaft extends out of the through hole and is connected to a rotating handle 7 .
[0036] The reset gear 5 is detachably connected to the rotary handle, which facilitates assembly and installation.
[0037] For example, in this example, the free end of the connecting shaft can be snap-fitted to the rotating handle. This structure is also a kind of detachable connection.
[0038] The side cover is provided with a reset mark near the through hole.
[0039] Embodiment 4: The characteristic of this embodiment is that the size of the rotating handle is larger than the diameter of the through hole, and the size of the through hole matches the size of the connecting shaft. This can make the through hole smaller and reduce the dust from entering the side cover. The rest is the same as embodiment 3.
[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
