Description

Technical Field

[0001] The utility model relates to the technical field of carbon powder boxes, in particular to a carbon powder box with an integrated trigger counting connecting rod structure. Background Art

[0002] In the printer that loads and uses the TN760 toner cartridge according to the prior art, the toner cartridge sensing element in the printer is arranged on one side of the conductive end cover of the toner cartridge. In the traditional TN760 toner cartridge, the stirring frame is often driven by the stirring frame gear to drive the stirring frame to operate, thereby driving the sensing element trigger structure located on the conductive end cover side of the toner cartridge to rotate. This scheme greatly increases the cost of optimizing the design of the toner cartridge. The stirring frame structure needs to be adjusted each time the optimization is performed. Therefore, some companies have improved the sensing element trigger structure, that is, the stirring frame driving method is cancelled and a counting gear connecting rod structure is used instead. Specifically, a counting gear is provided on one side of the stirring frame gear and is driven by the stirring frame gear meshing. The counting gear and the sensing element trigger structure are connected by a connecting rod, thereby triggering the sensing element of the printer.

[0003] In the above-mentioned improved design, when the toner cartridge is loaded into the printer, the counting gear driven by the stirring frame gear drives the sensing element trigger structure to toggle the trigger sensing element. When printing starts, the total capacity of the toner cartridge is sensed and identified, and this is used as the basis for subsequent printing volume monitoring. However, with this design, after the toner is exhausted, if the user chooses to refill the toner by himself and continue to use it, the conductive end cover and the gear end cover need to be removed separately, and the counting gear and the connecting rod structure need to be manually adjusted. The operation is cumbersome and error-prone, and is not user-friendly enough for ordinary users.

[0038] The counting linkage mechanism 113 is integrally formed by a connecting rod 1132 and a counting gear 1131 and a driving paddle wheel 1133 respectively arranged at both ends thereof.

The sensing lever 32 is arranged above the notch and interacts with the rotating paddle block on the surface of the driving paddle wheel 1133.

[0039] The reset component 33 includes a reset rod 331 and a reset spring 332.

The reset rod 331 is slidably connected in the reset rod mounting opening 312, and the reset spring 332 is connected between the spring positioning column 313 and the upper end of the reset rod 331.

[0040] The powder box assembly 1 is provided with a powder bin upper shell 11, and the powder bin upper shell 11 is provided with a connecting rod positioning groove 111. The counting connecting rod mechanism 113 is arranged in the connecting rod positioning groove 111, and the connecting rod positioning groove 111 is provided with a connecting rod head semicircular positioning key 112 at the end close to the driving gear assembly 2 and the induction detection assembly 3 respectively; the two ends of the connecting rod 1132 are respectively arranged in the two connecting rod head semicircular positioning keys 112.

[0041] Rib fasteners 1111 are provided at the upper parts of both ends of the connecting rod locating groove 111, a connecting rod cover plate 1112 is provided in the connecting rod locating groove 111, and oblique ribs 11121 are provided at both ends of the connecting rod cover plate 1112.

[0042] A reset extrusion piece 11332 is provided on the side of the driving wheel 1133 close to the powder box assembly 1, and is linked to the torsion spring 12 on the end face of the powder box assembly 1. When the empty tooth portion of the counting gear 1131 rotates to the direction facing the stirring frame gear 21, the driving wheel 1133 just completes one movement of the sensing lever 32, and the reset extrusion piece 11332 reaches the maximum compression state for the torsion spring 12; when the reset pull rod 331 is pulled away from the blocking block 11331, the torsion spring 12 drives the counting linkage mechanism 113 to reset.

[0043] The upper end of the sensing end cover 31 is provided with an extrusion fastener 314, and the extrusion fastener 314 is composed of an upper arc structure 3141 and a lower arc structure 3142. The upper end of the sensing lever 32 is provided with a sleeve portion 321, and the buckled end of the sleeve portion 321 is provided with a sliding inner bevel 322.

[0044] A conductive bracket 4 is provided on one side of the induction detection component 3, and a powder feeding roller conductive steel sheet 41 and a powder outlet knife conductive steel sheet 42 are buckled on the conductive bracket 4. The powder feeding roller conductive steel sheet 41 is in conductive contact with the powder feeding roller end 6 of the powder box component 1, and the contact end of the powder outlet knife conductive steel sheet 42 is buckled into the end buckle groove of the powder outlet knife 5 of the powder box component 1.

[0045] In summary, the specific implementation of the utility model is as follows: when the toner cartridge is put into use, the driving part of the printer is adapted to the driving gear of the driving gear assembly 2, and thereby engages and drives the stirring frame gear 21 to drive the stirring frame in the powder box assembly 1 to evenly stir the toner. At the same time, the stirring frame gear 21 engages and drives the counting gear 1131 to work, so that the driving dial 1133 at the other end of the connecting rod 1132 of the counting connecting rod mechanism 113 starts to rotate, and the rotating dial block on the driving dial 1133 dials the sensing dial rod 32, and the sensing dial rod 32 moves along the hinge located at the upper end of the sensing end cover 31. After the driving wheel 1133 is disengaged from the sensing lever 32, the sensing element of the printer rebounds and resets under the action of its own reset structure. At the same time, the sensing lever 32 is also pushed by the sensing element to rotate in the opposite direction and reset. After the driving wheel 1133 is disengaged from the sensing lever 32, the empty tooth portion of the counting gear 1131 is also rotated to a position meshing with the stirring rack gear 21, so that the stirring rack gear 21 can no longer drive the counting linkage mechanism 113.

[0046] In the process of the counting link mechanism 113 triggering the printer sensing element, the reset extrusion member 11332 of the driving dial 1133 squeezes the torsion spring 12 installed on the end surface of the powder box assembly 1 until the empty tooth portion of the counting gear 1131 also rotates to a position meshing with the stirring frame gear 21, and the reset extrusion member 11332 reaches the maximum compression state of the torsion spring 12, and the reset pull rod 331 blocks the rotation path of the blocking block 11331 on the driving dial 1133, preventing the torsion spring 12 from exerting a reset force on the reset extrusion member 11332, thereby resetting the counting link mechanism 113;

[0047] When the toner is used up and the user needs to refill the toner cartridge, the user pulls the reset rod 331 to make it leave the blocking block 11331 on the driving dial 1133. The reset force applied by the torsion spring 12 to the reset extruder 11332 resets the counting linkage 113, that is, the counting gear 1131 is driven to rotate, so that the starting end of the counting gear 1131 is meshed with the agitator frame gear 21 again.

[0048] The above description is only the optimal solution embodiment of the present invention and is not intended to limit the present invention. Various modifications or substitutions made to the present invention by those skilled in the art without departing from the essence and protection scope of the present invention should also be within the protection scope of the present invention.
