Description

Technical Field

[0001] This invention relates to a printer, and more particularly to a toner cartridge counting gear button reset and zeroing structure. Background Technology

[0002] Currently, most toner cartridges on the market (such as Brother, Lenovo, and other laser printer toner cartridges) have a reset counter gear. When the toner cartridge is first installed in the printer, the counter gear will rotate and touch the counter component inside the printer to complete the reset, and then stay in a specific position and stop rotating.

[0003] When the preset number of pages is reached or the toner cartridge is removed and refilled, the printer needs to reset the counter gear to re-trigger the counter before printing can continue. Toner cartridge "reset" means eliminating the printer's memory of the old toner cartridge, allowing it to continue printing and increasing print volume. Brother, Lenovo, and other brands primarily use a counter gear to count pages; after refilling, the counter gear must be installed back to its starting position (reset) before printing can continue. The counter reset component of the 770 series toner cartridges is particularly complex. After testing at the manufacturing plant or after refilling, the toner cartridge must be disassembled, the counter gear manually reset, and the counter gear and transmission gear reassembled to their initial positions. Otherwise, the printer will not recognize the toner cartridge, rendering it unusable. Most users do not know how to reset the counter gear; this requires a professional, significantly increasing the difficulty of using the product and limiting the reuse of the toner cartridge.

[0004] Therefore, some toner cartridges on the market now have automatic resetting counting gears. However, if a paper jam or other issue occurs and the toner cartridge needs to be removed, the counting gears will automatically rotate and restart the count. This causes the printer to fail to prompt for a toner cartridge replacement when the toner is depleted and to fail to provide an accurate page count.

[0005] Therefore, in response to the above situation, the applicant designed a toner cartridge counting gear button reset and zeroing structure to solve the above problems. Summary of the Invention

[0006] To overcome the shortcomings of the prior art, the present invention provides a toner cartridge counting gear button reset and zeroing structure.

[0007] The technical solution adopted by this invention to solve its technical problem is:

[0008] A toner cartridge counting gear button reset and zeroing structure includes a counting gear and a side cover. The side cover has a reset rod and a reset button. The counting gear has a limiting paddle that abuts against the reset rod, thus keeping the counting gear in an idle position. A first elastic element is provided between the reset rod and the side cover to extend the reset rod. A second elastic element is provided between the limiting paddle and the side cover to drive the counting gear to rotate. The reset rod can be retracted by the reset button to avoid abutting against the limiting paddle.

[0009] The reset rod includes a rod cap and a rod body. The side cover is provided with a mounting hole and a through hole. The rod cap is located in the mounting hole. The rod body passes through the through hole and abuts against the limiting piece. The elastic element is located in the mounting hole and can squeeze the rod cap.

[0010] The reset button is rotatably connected to the side cover, and the reset button includes a push end and a press end located on both sides of the rotatable connection point. The push end is provided with a clearance hole, and the push end is located between the rod cap and the side cover. The rod body also passes through the clearance hole.

[0011] The elastic element is a compression spring, one end of which abuts against the bottom of the mounting hole, and the other end of which abuts against the rod cap.

[0012] The side cover is provided with a reset seat, the mounting hole is provided in the reset seat, and the reset button is rotatably connected to the reset seat.

[0013] The reset button is provided with a rotating shaft, and the reset seat is provided with a shaft hole that rotates and engages with the rotating shaft.

[0014] The reset seat is provided with several elastic feet, and the side cover is provided with a locking hole. The elastic feet can be inserted into the locking hole and locked with the locking hole by the locking block on the elastic foot.

[0015] The side cover is provided with a positioning rod, and the second elastic element is a torsion spring. The torsion spring is set on the positioning rod, and one torsion arm of the torsion spring abuts against the limiting piece.

[0016] The beneficial effects of this invention are as follows: The side cover is equipped with an elastic element, a reset rod, and a reset button. A limiting plate is provided on the counting gear. Therefore, when the counting gear stops at a specific position, the elastic element will press the limiting plate, causing the counting gear to rotate. However, the reset rod will restrict the limiting plate, keeping the counting gear stationary. When the toner cartridge runs out of toner or prints the preset number of sheets, the counting gear will not automatically reset, prompting the printer to issue a message to replace the toner cartridge. This allows the user to easily know when toner needs to be added. After refilling, simply press the reset button manually. The reset element drives the reset rod to retract, no longer restricting the limiting plate. Under the pressure of the elastic element, the limiting plate causes the counting gear to rotate, thus passing the specific position and re-contacting the counter component, completing the zeroing process. The printer can then restart counting and printing.

[0017] The above structure is easy to operate, requiring no disassembly of the toner cartridge or reassembly of the counting gear and transmission gear, thus providing great convenience to users, while retaining the printer's original functions of toner cartridge replacement prompts and accurate page counting.

[0024] The advantages and features of this disclosure, as well as its implementation methods, will be illustrated by the following embodiments described with reference to the accompanying drawings. However, this disclosure may be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be comprehensive and complete, and will fully convey the scope of this disclosure to those skilled in the art. Furthermore, this disclosure is limited only by the scope of the claims.

[0025] The shapes, dimensions, scales, angles, and numbers disclosed in the accompanying drawings used to describe embodiments of this disclosure are merely examples, and therefore this disclosure is not limited to the details shown. Throughout this specification, the same reference numerals refer to the same elements. In the following description, detailed descriptions of relevant known functions or configurations will be omitted where it is determined that such detailed descriptions would unnecessarily obscure the focus of this disclosure. Where the terms “comprising,” “having,” and “including” are used in this specification, additional components may be added unless “only” is used. Unless otherwise indicated, singular terms may include plural forms.

[0026] When interpreting components, even if not explicitly described, the components are understood to include a range of tolerances.

[0027] When describing positional relationships, such as "on," "above," "below," and "adjacent to," one or more parts may be arranged between two other parts unless "immediately following" or "directly" is used.

[0028] When describing temporal relationships, such as when time sequence is described as “after,” “following,” “next,” and “before,” discontinuous cases may be included unless “exactly” or “directly” is used.

[0029] It should be understood that although the terms “first,” “second,” etc., may be used herein to describe various elements, these elements should not be limited by these terms. These terms are used only to distinguish one element from other elements. For example, a first element may be referred to as a second element, and similarly, a second element may be referred to as a first element, without departing from the scope of this disclosure.

[0030] As will be fully understood by those skilled in the art, the features of the different embodiments of this disclosure may be coupled or combined with each other in part or in whole, and may cooperate with each other and be technically driven in various ways. The embodiments of this disclosure may be implemented independently of each other, or may be implemented together in an interdependent relationship.

[0031] Reference Figures 1 to 5This invention discloses a toner cartridge counting gear button reset and zeroing structure, including a counting gear 1, a side cover 2, and a transmission gear 3. The transmission gear 3 is connected to the stirring roller to provide power. The counting gear 1 has a toothed segment and a blank segment on its edge, and a lever 4 on its end face. When the transmission gear 3 meshes with the toothed segment, it drives the counting gear 1 to rotate. Then, the lever 4 rotates to the corresponding position to touch the counter component. Finally, when the counting gear 1 rotates to the blank segment and is close to the transmission gear 3, the transmission gear 3 disengages from the counting gear 1, thus preventing it from driving the counting gear 1 to rotate. At this point, the counting gear 1 is in a specific position. To reset the counting gear 1, the toner cartridge and the counting gear 1 and transmission gear 3 need to be disassembled and reassembled so that the counting gear 1 and transmission gear 3 re-mesh. The above structure and principle are the same as the counting principle of the counting gear 1 in the previous structure.

[0032] As shown in the figure, the side cover 2 of this application is provided with a reset rod and a reset button, and the counting gear 1 is provided with a limiting plate 5. The limiting plate 5 can abut against the reset rod, thereby keeping the counting gear 1 in the free-spinning position. There is an elastic element 6 between the reset rod and the side cover 2 to extend the reset rod, and there is an elastic element 7 between the limiting plate 5 and the side cover 2 to drive the counting gear 1 to rotate. The reset rod can be retracted by pushing the reset button to avoid abutting against the limiting plate 5. With the above structure, we only need to manually press the reset button to reset the counting gear 1 and make it rotate again. The operation is simple and convenient, and the previous prompt function is retained.

[0033] As shown in the figure, the reset rod includes a circular cap 8 and a rod body 9. The diameter of the cap 8 is larger than that of the rod body 9. The side cover 2 is provided with a mounting hole 10 and a through hole 11. The cap 8 is located in the mounting hole 10. The rod body 9 passes through the through hole 11 and abuts against the limiting piece 5. The cap 8 cannot pass through the through hole 11. The elastic element 6 is located in the mounting hole 10 and can squeeze the cap 8. In this way, the elastic element 6 can keep the reset rod in an extended state, thereby abutting against the limiting piece 5 and preventing the limiting piece 5 from rotating under the drive of the elastic element 7.

[0034] As a specific structure, the reset button is rotatably connected to the side cover 2, and the reset button includes a push end 12 and a press end 13 located on both sides of the rotation connection point. The push end 12 is provided with a clearance hole 14, and the push end 12 is located between the rod cap 8 and the side cover 2. The reset rod also passes through the clearance hole 14. With the above structure, the user only needs to press the press end 13 to rotate the push end 12 through the rotation connection point, thereby pushing the rod cap 8 to rise and retract. This structure not only allows us to make full use of the structure inside the toner cartridge, but also has a lever principle, which allows the press end 13 to be designed to be farther from the rotation connection point and the push end 12 to be closer to the rotation connection point, making it easier and less strenuous for the user to press.

[0035] As a preferred embodiment, the elastic element 6 is a compression spring, one end of which abuts against the bottom of the mounting hole 10, and the other end of which abuts against the rod cap 8.

[0036] As shown in the figure, for ease of processing and assembly, the side cover 2 is provided with a reset seat 15, the mounting hole 10 is provided in the reset seat 15, and the reset button is rotatably connected to the reset seat 15. Specifically, the reset button is provided with a rotating shaft 16, and the reset seat 15 is provided with a shaft hole 17 that rotatably engages with the rotating shaft 16. The shaft hole 17 on the reset seat 15 is open, which makes it easy for the rotating shaft 16 to be inserted into the shaft hole 17 from the opening. However, when the reset seat 15 is installed on the side cover 2, the surface of the side cover 2 can close the opening of the shaft hole 17, thereby preventing the rotating shaft 16 from coming out.

[0037] As shown in the figure, the specific installation structure of the reset base 15 is as follows: the reset base 15 is provided with a plurality of elastic feet 18, the side cover 2 is provided with a locking hole 19, the elastic feet 18 can be inserted into the locking hole 19 and locked with the locking hole 19 by the locking block on the elastic feet 18.

[0038] As shown in the figure, the side cover 2 is provided with a positioning rod 20, and the elastic element 7 is a torsion spring. The torsion spring is set on the positioning rod 20, and one torsion arm of the torsion spring abuts against the limiting plate 5. The other torsion arm of the torsion spring is fixed to the side cover 2. When the reset rod is retracted by pressing, one torsion arm of the torsion spring pushes the limiting plate 5, thereby causing the counting gear 1 to rotate and pass a specific position, so that the tooth segment re-meshes with the transmission gear 3. Then the transmission gear 3 can drive the counting gear 1 to rotate again, and then the lever 4 will also rotate to the corresponding position to touch the counter component, thereby realizing the printer to complete the zeroing work, and the printer can start counting again and printing again.

[0039] The above provides a detailed description of a toner cartridge counting gear button reset and zeroing structure provided by the embodiments of the present invention. Specific examples have been used to illustrate the principle and implementation of the present invention. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​the present invention. Therefore, the content of this specification should not be construed as a limitation of the present invention.
