Referring to fig. 1 to 5, a counting trigger mechanism of a developing cartridge includes: a developing cartridge 10, a power gear 20, a transmission gear 30, a trigger 40, and a protective cover 50. The power gear 20 is rotatably provided on the developing cartridge 10 and is connected with a rotating member inside the developing cartridge 10. The transmission gear 30 is rotatably provided on the developing cartridge 10. The power gear 20 is engaged with the driving gear 30. The transmission gear 30 is provided with a transmission hole 31. The trigger 40 is rotatably fitted over one side of the developing cartridge 10. The trigger 40 is rotatable with the drive gear 30. The trigger 40 may trigger a counter. The protection cover 50 is provided on the developing cartridge 10. The protective cover 50 is sleeved on the power gear 20 and the transmission gear 30.

Further, referring to fig. 3 to 6, the trigger 40 includes: a sleeve 41, a toggle portion 42 and a transmission portion 43. The sleeve 41 is rotatably provided at one side of the developing cartridge 10. The toggle part 42 is provided on the sleeve 41. The toggle part 42 rotates with the sleeve 41. The toggle 42 may trigger a counter. The transmission portion 43 is provided at one end of the sleeve 41. The transmission portion 43 is inserted in the transmission hole 31. The transmission part 43 can drive the sleeve 41 to rotate synchronously with the transmission gear 30.

It is understood that in the embodiment of the present invention, the sleeve 41 is coaxial with the transmission gear 30, and when the transmission portion 43 is inserted into the transmission hole 31, the transmission gear 30 rotates to drive the trigger 40 to rotate synchronously. At this point the toggle 42 swings to trigger the counter to count. After the metered output paper reaches a set value, the printer lifts and changes the developing box, so that the waste of the paper can be avoided.

It is noted that in some embodiments of the present invention, the transmission portion 43 is a transmission strap. In some other embodiments of the present invention, the transmission part 43 may also be other embodiments such as a transmission rod, a transmission ball, etc., as long as the function of synchronous transmission can be satisfied.

Referring to fig. 3-9, the trigger 40 further includes a disengagement assembly 44. The disengaging assembly 44 includes: a slide paddle 441 and a lift rail 442. A slide paddle 441 is provided on the sleeve 41. The sliding paddle 441 is provided with a slot 441 a. The rising rail 442 is provided on the shield 50. The riser rail 442 is a spiral track. The engaging groove 441a is fitted over the rising rail 442. The rising rail 442 has an insertion groove 442 a. The insertion groove 442a is for mounting the slide paddle 441. The locking groove 441a can slide along the ascending guide 442 and drive the sleeve 41 to move axially along the sleeve 41, so that the transmission portion 43 is separated from the transmission gear 30.

It should be noted that the ascending guide 442 has a spiral shape as shown in fig. 7 and 9, and the slot 441a can slide along the ascending guide 442. When the trigger 40 and the transmission gear 30 rotate synchronously, the driving slot 441a slides along the ascending guide rail 442, at this time, under the guidance of the spiral inclined surface of the ascending guide rail 442, the trigger 40 is centered along its rotation axis and gradually separated from the transmission gear 30, and the transmission part 43 gradually comes out of the transmission hole 31, and when the slot 441a moves to the end of the ascending guide rail 442, the transmission part 43 is completely separated from the transmission hole 31. By this time the trigger 40 stops rotating and does not interfere with the continued rotation of the drive gear 30.

Further, it is worth mentioning that the sliding dial 441 may enable the printer to detect the insertion of the developing cartridge 10 when the developing cartridge 10 is inserted into the printer, and the printer may not operate if the printer does not detect the developing cartridge 10. The protection of the printer can be achieved to prevent the printer from running and being damaged when the developing cartridge 10 is not present.

Referring to fig. 7 and 9, a backstop 442b is further provided on the elevation rail 442. Backstop 442b serves to prevent slide paddle 441 from sliding in the reverse direction.

It is understood that the non-return stopper 442b prevents the sliding paddle 441 from sliding backward, avoiding mechanical failure.

Further, in some embodiments of the present invention, the cross-section of the riser rail 442 is rectangular, trapezoidal, triangular, or semi-circular, among other shapes.

Of course, it should be noted that the cross-sectional shape of the lifting rail 442 may be rotated as required by those skilled in the art, as long as the lifting rail can slide in cooperation with the engaging groove 441a to separate the transmission part 43 from the transmission hole 31.

Further, the trigger 40 is made of plastic.

It can be understood that the trigger 40 is made of plastic material, and the trigger 40 made of plastic material has the advantages of low production cost, easy replacement, etc.

Referring to fig. 7, the shield 50 is further provided with a lower barrier 51.

Furthermore, the lower baffle 51 can prevent sundry residues from falling into the transmission part, and the failure rate is reduced.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
