Description
Technical field
The present invention relates to a kind of developer replenishing container being releasably attached to developer receiving equipment, can use together with electro photography type imaging device (such as copy, facsimile recorder, printer or there is the composite machine of several functions of described duplicating machine, facsimile recorder and typewriter).
Background technology
Electro photography type imaging device has graphics processing unit and developing cell usually, the developers (toner) such as the carbon dust utilizing developing cell to provide, for the latent electrostatic image developing that graphics processing unit is formed to form visual picture on the media such as paper.Wherein developer is as consumables, needs constantly to supplement in electro photography type imaging device.General employing is releasably attached to the supply container of accommodating a certain amount of developer that has of developing cell in electro photography type imaging device and provides developer to developing cell.
See figures.1.and.2, Fig. 1 and Fig. 2 is exploded view and the cut-open view of a kind of developer replenishing container that can be removably mounted on developer replenishing apparatus disclosed in prior art.Developer replenishing container 100 comprises: resettlement section 110, for accommodating developer; Feed portion 120, for carrying out the developer in feed resettlement section 110 along with the rotation in feed portion 120; Discharge side 130, is provided with the escape hole 131 for allowing the developer of feed portion 120 feed to discharge; Pumping section 140, for acting at least discharge side 130, and has the volume changed along with moving back and forth; Driving force acceptance division 111, for receiving the rotating force making resettlement section 110 rotate from developer replenishing apparatus; Drive converter section 150, the rotating force for being received by driving force acceptance division 111 is converted to the power that pumping section 140 is operated.
Wherein, pumping section 140 scalable and this flexible being enough to utilizes volume to change the interior pressure changing developer replenishing container 100.Drive converter section 150 to drive pumping section 140 to do axial stretching action, drive between developer replenishing container 100 air pressure inside positive/negative-pressure and back and forth change.Under the effect of pumping section 140 normal pressure, developer flows out from escape hole 131, and enters into developing cell.When in pumping section 140 reinstatement process, negative pressure drives the developer of developer replenishing container 100 inside, makes internal development agent keep fluffy state, avoids caking.
But pumping section 140 has the volume changed along with moving back and forth and presses to change in developer replenishing container 100, intermittently can only supply developer to escape hole 131.Moreover, when in pumping section 140 reinstatement process, there is negative pressure by the situation of developer toward resorption, cause developer replenishing to have some setbacks.Further, after the repeatedly action moved back and forth of pumping section 140, the scalable performance of pumping section 140 will decline, thus the situation causing developer replenishing uneven.
Further, pumping section 140 axially ceaselessly moving at supply container, the junction of the wall portion of itself and discharge side 130 also usually occurs loosening because of the existence of axial tension, thus causes the leakage of developer.
Summary of the invention
In order to solve the problem, it is simple and have the developer replenishing container of better sealing property that fundamental purpose of the present invention is to provide a kind of developer, structure of can supplying unidirectional continuous uniform.
Another object of the present invention is to provide a kind of method utilizing above-mentioned developer replenishing container to carry out supplying developer.

As can be seen here, receive rotating force by the first gear of gear-type pump or the second gear and drive two gears to intermesh rotations, thus drive developer is discharged from developer outlet opening.The rotation of gear-type pump is synchronized with reception room, can unidirectional continuous uniform ground supply developer.Because gear pump structure is simple, and connect firm, also improve the reliability of developer replenishing.And, relatively rotate between reception room and discharge side and do not produce axial deformation or axial tension, there is good sealing property.
Further scheme is, developer replenishing container also comprises the transfer part for rotating force to be sent to gear-type pump from reception room, and transfer part comprises engaged wheel and the connecting rod for being connected with the first gear or the second gear by engaged wheel.
Visible, transfer part is made up of engaged wheel and connecting rod, and structure is simple, reliable operation.
Further scheme is, the outside surface of resettlement section is provided with the gear part for driving engaged wheel to rotate, gear part axial distance relative to developer replenishing mouth closer to driving force acceptance division.
As can be seen here, gear part is closer to driving force acceptance division, and improve the diameter run-out precision of gear part, transmission performance is reliable.
Further scheme is, the bottom of discharge side is provided with for the first support portion of support teeth wheel pump, the second support portion and the 3rd support portion, first support portion and the second support portion lay respectively at gear pump shaft to both sides, the 3rd support zone in follower shaft to side.
Visible, the bottom of discharge side is provided with support portion for supporting the position limiting gear-type pump and engaged wheel, is conducive to the accuracy of transmission, improves the reliability of gear-type pump supply developer.
In order to realize another above-mentioned object, the invention provides a kind of developer supply method, this developer supply method uses above-mentioned developer replenishing container to carry out supply developer, in the process of developer replenishing, developer replenishing container is mounted on developer replenishing apparatus, developer replenishing apparatus drives driving force acceptance division, driving force acceptance division provides the rotating force that resettlement section is rotated, along with the rotation developer movement of resettlement section to developer replenishing mouth, developer replenishing confession send the gear-type pump of developer to being positioned at discharge side, developer is delivered to developer outlet opening by gear-type pump under rotating force drives.
