Abstract

The utility model discloses a toner cartridge, and aims at providing a toner cartridge with a simple structure and a capability of being successfully recycled without dismantling a gear end cover. The toner cartridge comprises a counting tooth (7), a toner cartridge main body (9) and a gear end cover (5) matched with the side part of the toner cartridge main body (9), wherein the counting tooth (7) is arranged on the outer side of the gear end cover (5), the inner side of the counting tooth (7) is in transmission connection with a transmission mechanism inside the toner cartridge main body (9), at least one clamping pin (8) is arranged at the top of the counting tooth (7), the bottom of the counting tooth (7) is cylindrical, no interference rotation exists between the bottom of the counting tooth (7) and the inner side of the gear end cover (5), a limit block (6) used for locating the clamping pin (8) is arranged on the outer side of the gear end cover (5), and the limit block (6) can enable the counting tooth (7) to stop in a correct position during rotation. The utility model can be widely applied to the field of toner cartridges.

Description

A kind of cartridge

Technical field

The utility model relates to a kind of cartridge.

Background technology

Powder box installation back printer is recognized machine has dual mode, and the one, recognize machine through chip counter, the 2nd, recognize machine through counting tooth counting.Wherein, counting tooth counting is recognized the machine process and is: after newly powder box was packed printer into, the rotation of printer driver gear was rotated through the counting of the gear set drive on powder box tooth, and the card base on counting tooth top is dialed the counter switch of printer; Only less than the half-turn profile of tooth, blocked by the inner position-limit foot of gear end cap after the counting tooth half turn, thereby be parked in a fixed position on the counting tooth, the counter switch of a card base jack-up printer on counting tooth top; Printer is recognized the machine completion, and the machinery panel green light is bright, and is ready.When the printer powder box exhausted serviceable life, the machinery panel amber light was bright, and the prompting powder box life-span is most, can not continue to print again, and this moment, powder box must take out regeneration from printer, added carbon dust, and made the counting tooth reset to initial position; Or count tooth counting quota and turn to stuck position, need powder box be taken out regeneration equally.

Yet the cartridge under the prior art; Like Fig. 1, Fig. 2, shown in Figure 3; Because the technology shortcoming is perfect, the powder box that the life-span is used up is because the location card base 4 that gear end cap 1 inner spacing card base 2 will be counted on the tooth 3 blocks, and the counting tooth can not rotate for 3 this moments; The staff can only take gear end cap 1 apart and could will count tooth 3 initial position is installed back, and powder box could reproductive success.In addition, present powder box capacity can suitably increase, however the counting tooth of cartridge count down to one regularly can be stuck automatically, at this moment also must take out powder box regeneration, can more fully utilize the carbon dust in the powder box.Therefore, the powder box regenerative process all must be according to this job step each time, and the staff that this process of dismounting cartridge is generally also only known cartridge just can operate, and is extremely not convenient, obviously increases many troubles to related work.

The utility model content

The utility model technical matters to be solved is the deficiency that overcomes prior art, provide a kind of simple in structure, need not to take apart the cartridge that the gear end cap just can make the powder box reproductive success.

The technical scheme that the utility model adopted is: the utility model comprise counting tooth, powder box main body, with the adaptive gear end cap of said powder box main body sidepiece; Said counting tooth is located at the said gear end cap outside; The inboard gear train with said powder box body interior of said counting tooth is in transmission connection; The top of said counting tooth is provided with at least one card base; The bottom of said counting tooth is cylindrical shape and does not have interference rotation with the inboard of said gear end cap, and the outside of said gear end cap is provided with the limited block that is used to locate said card base.

Preferably, said limited block is made as ramped shaped, is convenient to said card base and crosses said limited block.

The beneficial effect of the utility model is: because the utility model has been cancelled the location card base of counting tooth bottom on the basis of existing technology; Therefore rotatablely moving of counting tooth can not be limited in gear end cap inboard; And withstand the printer switch in order to make the counting tooth when recognizing the machine rotation, stop at the fixed position; Be provided with a limited block in the outside of gear end cap, stop at the tram when making the counting tooth recognize the machine rotation.The cartridge of this structure need not be taken the gear end cap apart in the time of will making powder box regeneration, directly will count tooth and be rotated counterclockwise, and makes it cross limited block, gets back to initial position the counting tooth is resetted, and powder box is the ability reproductive success just; Said limited block is made as ramped shaped, and operability is stronger.

Embodiment

Like Fig. 4, Fig. 5, shown in Figure 6; The utility model relates to a kind of improved cartridge structure that under prior art, is optimized; It comprises powder box main body 9, with the adaptive gear end cap 5 of said powder box main body 9 sidepieces, said counting tooth 7 is located at the outside of said gear end cap 5, the gear trains of the inboard of said counting tooth 7 and said powder box main body 9 inside are in transmission connection; During the printer action, said gear train drives said counting tooth 7 and rotates; The said counting tooth 7 relatively counting tooth of prior art has reduced the location card base, surveys not have when rotatablely moving and in the said gear end cap 5 and interferes; The outside of said counting tooth 7 is provided with three card bases 8; Be provided with the limited block 6 that is used to locate said card base 8 in the outside of said gear end cap 5; Said limited block 6 can make said card base 8 when said counting tooth 7 is recognized the machine rotation, stop on the correct position, thereby makes the powder box reproductive success of printer.When printer because of powder box in the not enough or said counting tooth 7 of carbon dust when reaching stuck position and quitting work; Only need the said counting tooth 7 moving suitable distance of layback outward; Be rotated counterclockwise and make it to cross said limited block 6 in said counting tooth 7 then; Getting back to initial position makes said counting tooth 7 reset the powder box reproductive success.Said limited block 6 is made as ramped shaped, is convenient to said counting tooth 7 and crosses said limited block 6, accomplish homing action.The great advantage of the cartridge of this structure need not to take apart said gear end cap 5 exactly just can make the powder box reproductive success, convenient to use, workable.

In sum, the utility model can be widely used in the cartridge field.
