Referring to fig. 1 to 4, a turn-over type developing cartridge counting switch includes: a developing cartridge 10, a power gear 20, and a transmission gear 30. 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 drive gear 30 is an incomplete gear. The drive gear 30 can trigger a counter in the printer. When the drive gear 30 triggers a counter in the printer and the counter starts counting, the drive gear 30 is disengaged from the power gear 20. The driving gear 30 is provided with a flap assembly 31. The flap assembly 31 can drive the internal structure of the printer to rotate to trigger the counter.
It should be noted that the counter trigger 40 is provided inside the printer, and the counter trigger 40 is rotatably provided on the printer. The count trigger 40 is electrically connected to the counter. The transmission gear 30 can drive the counting trigger piece to rotate.
It can be understood that when the developing cartridge 10 starts to operate, the rotating component inside the developing cartridge 10 drives the power gear 20 to rotate, which drives the transmission gear 30 and the counting trigger 40 to rotate, so that the counting trigger 40 starts the counter, and the counter starts counting the number of paper sheets output by the printer. When the counter detects that the number of sheets output from the printer reaches a set value, replacement of the developing cartridge 10 is prompted.
Further, referring to fig. 4, the transmission gear 30 is an incomplete gear. When the transmission gear 30 drives the counting triggering part 40 to rotate and the counter starts counting, the transmission gear 30 is meshed with the power gear 20 and is disconnected.
It can be understood that, the gear teeth on the transmission gear 30 are not provided with a full circle, when the transmission gear 30 rotates to a certain position, the counting triggering member 40 is driven to rotate and the counter is triggered to count, the transmission gear 30 is meshed with the power gear 20 and is disconnected, and the transmission gear 30 does not rotate any more.
Referring to fig. 1 to 8, a flap assembly 31 is disposed on the transmission gear 30. The counting trigger 40 is provided with a first protrusion 41. The flap assembly 31 can abut against the first protrusion 41 to drive the counting trigger 40 to rotate.
Further, referring to fig. 4 and 7, the flap assembly 31 includes: a flap 311 and a torsion spring 312. The flap 311 is hinged on the transmission gear 30. One end of the torsion spring 312 abuts against the transmission gear 30, and the other end abuts against the turning plate 311. The torsion spring 312 is used for resetting the flap 311.
Of course, it should be noted that the flap assembly 31 can rotate along with the transmission gear 30 and abut against the first protrusion 41, so as to drive the counting trigger 40 to rotate. The counting trigger 40 is electrically connected with the counter, and when the flap assembly 31 drives the counting trigger 40 to rotate, the counter is started.
Further, in some other embodiments of the present invention, the flap 311 is made of plastic.
It can be understood that the turning plate 311 is made of plastic material, and the turning plate 311 made of plastic material has the advantages of low production cost, easy replacement, etc.
Referring to fig. 1 to 3 and 6, the turn-over type developing cartridge counter switch further includes a protective case 50. The protective casing 50 is provided on the developing cartridge 10. The protective shell 50 is sleeved on the power gear 20 and the transmission gear 30.
It can be understood that the protective shell 50 is sleeved on the power gear 20 and the transmission gear 30, and the rotating component can be isolated from the outside by the protective shell 50, so that dust and impurities are prevented from entering the rotating component and affecting the rotation. Meanwhile, when the developing box is replaced, people can be prevented from contacting the rotating part, and injuries are avoided.
Further, referring to fig. 3 and 6, the protective case 50 is provided with a trigger protrusion 51. The trigger protrusion 51 may trigger the counter. In detail, the counting trigger 40 is further provided with a second protrusion 42. When the developing cartridge 10 is inserted into the printer, the trigger protrusion 51 abuts against the second protrusion 42 and drives the counter trigger 40 to rotate.
Of course, it should be noted that when the developing cartridge 10 is inserted into the printer, the triggering protrusion 51 may abut against the second protrusion 42 and drive the counting triggering member 40 to rotate, so that the printer can detect that the developing cartridge 10 is inserted, and if the printer does not detect the developing cartridge 10, the printer does not work. 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.
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.
