A counter reset mechanism according to an embodiment of the present utility model is described below with reference to fig. 1 and 2.

The specific implementation manner of this embodiment is as follows:

as shown in fig. 1 and 2, the counter reset mechanism according to the embodiment of the present utility model includes a housing 100, a locking member 200, and a counter gear 300. A round hole 101 is formed in the shell 100; the locking member 200 is installed at the circular hole 101 at the top of the housing 100; the counter gear 300 includes a gear shaft 310, a stopper is provided on the gear shaft 310, the locking member 200 is perpendicular to the axial direction of the counter gear 300, and the locking member 200 can abut against the stopper.

As shown in fig. 2 and 3, it will be appreciated that in some embodiments, the locking member 200 includes a latch 201 and a spring 202, where the latch 201 includes a first cylinder 211 and a second cylinder 212, the first cylinder 211 has a radius greater than that of the second cylinder 212, the spring 202 is sleeved on the second cylinder 212, a first end of the spring 202 abuts against a protrusion where the circular hole 101 is located, and a second end of the spring 202 abuts against the first cylinder 211.

As further shown in fig. 2, it is understood that in some of these embodiments, the end of the latch 201 adjacent the gear shaft 310 is a beveled structure. The gear shaft 310 comprises a limiting block 311, and the limiting block 311 is matched with the inclined surface structure of the plug 201.

As shown in fig. 1, it will be appreciated that in some embodiments, a drive gear 400 is also included, the drive gear 400 being engageable with the counter gear 300. Counter gear 300 includes a toothed surface 321 and a non-toothed surface 322.

As shown in fig. 1, it will be appreciated that in some of these embodiments, a torsion spring 500 is also included, the torsion spring 500 being mounted to the underside of the counter gear 300. Illustratively, a mounting post is provided on the housing, the torsion spring is mounted on the mounting post, a first end of the torsion spring is in abutment with the drive gear, for example, an abutment plane is provided on the gear shaft, a first end of the torsion spring is in abutment with the abutment plane, and a second end of the torsion spring is in abutment with the housing, for example, an abutment post is provided on the housing.

The embodiment provides a toner cartridge, which comprises the counting reset mechanism according to the utility model, and further comprises a developing cartridge and a drum cartridge. The mounting position between the developing cartridge and the drum cartridge is generally narrow.

As shown in fig. 4, when the toner cartridge is reloaded into the printer, the front end of the toothed surface 121 of the counter gear is in engagement with the transfer gear. When the new toner cartridge is loaded into the printer and the power is turned on, the transmission gear 400 drives the counting gear 300 to rotate; as the counter gear 300 rotates forward, the counter gear 300 and the transmission gear 400 are disengaged from the engagement of the toothed surface 321 to the non-toothed surface 322, and the transmission gear 400 stops rotating; the first end of the latch 201 abuts against the abutment 610 of the drum cartridge 600, and the second end of the latch 201 extends into the rotational path of the stopper of the gear shaft 310 to block the continued rotation of the gear shaft 310. The count reset mechanism completes the count reset operation and the toner cartridge is in a ready-to-print state.

In the printing process, if the printer jams and other conditions occur, and the developing box is pulled out together with the drum box under the condition that the developing box has no problem, the locking part 200 rotates and limits the gear shaft 310, and the counting gear 300 cannot rotate; at this time, the position of the counter gear 300 in the axial direction has been separated from the printer body, but the drum cartridge 600 is not yet separated from the lock member 200 and continues to apply the pushing force to the lock member 200. Therefore, the counting can not be reset again, and the original true counting is reserved.

When printing is not clear, the developing box can be charged with carbon powder, and then the printing is required to be recounted. Lifting the developing cartridge upward to separate the developing cartridge from the drum cartridge, the drum cartridge removing the pressure applied to the locking member 200, and the latch being separated from the rotational path of the gear shaft; the torsion spring 500 rotates and toggles the counter gear 300 to engage the transfer gear 400 to begin resetting and recounting. After the carbon powder is replaced, the developing box is arranged in the drum box, so that the bolt 201 is pressed inwards; the first end of the latch 201 abuts against the drum box, and the second end of the latch 201 extends into the rotational path of the gear shaft 310 stopper to block the continued rotation of the gear shaft 310. The counting reset mechanism completes the counting reset work, and the toner cartridge is in a ready-to-print state.

The embodiment provides a printer, which comprises the toner cartridge according to the utility model, wherein the toner cartridge comprises the counting reset mechanism, a developing cartridge and a drum cartridge.

According to the printer provided by the embodiment of the utility model, by adopting the counting reset mechanism, the flexible reset counting is realized, the counting accuracy of the toner cartridge is improved, the printer jam and other conditions are conveniently treated, the cost is saved, and the printing quality is improved.
