Description
Technical field
The utility model relates to electrophotographic image forming fields, specifically, being to be related to a kind of be used for imaging device supply
The powder box of carbon dust.
Background technique
Electrophotographic image forming such as laser printer is a kind of using electrofax principle, at least through charging, cruelly
Light, development, transfer, fixing and clean process form the equipment of image on image forming medium such as paper.Imaging device
On the material of easy consumption that uses, be generally called printing consumables, existing printing consumables is usually carbon dust.Usually consumed by development
Carbon dust is generally provided by powder box, after the carbon dust in powder box is finished, then the powder box more renewed.
As shown in Figure 1, a kind of existing powder box includes box body 101, carbon dust supply unit, lid 102, lid 103 and side cover 104.
Box body 101 has the powder cabin for accommodating carbon dust, and lid 102 is arranged in one end of box body 101, offers meal outlet on lid 102
1021, meal outlet 1021 is used to for the carbon dust in powder cabin being discharged.It is provided in lid 102 for opening and closing meal outlet 1021
Switch portion 105, and the free end side in switch portion 105 close to lid 102 is provided with switch protrusion 1051, switch portion 105
Peripheral wall is equipped with communication port, and when meal outlet 1021 is opened, communication port is corresponding with meal outlet 1021.
By the unitary rotation of powder box, while switch protrusion 1051 is fixed to realize the opening and closing of meal outlet.Therefore
A meal outlet will be specially arranged by needing outside the carbon dust supply unit inside lid 102 turns on the switch, i.e. switch portion 105.Due to
Switch portion 105 is arranged in lid 102, and lid 102 is connected with carbon dust supply unit, since switch portion 105 is fixed at meal outlet
It is interior, therefore powder feeding effect will be limited by 105 structure of switch portion.
Carbon dust supply unit is used to inside powder cabin convey carbon dust to meal outlet.Lid 102 has multiple gear teeth 1022,
Multiple gear teeth 1022 are located on the circumferential surface of lid 102.Due to being provided with gear teeth 1022 on lid 102, which is used for
Keep the development switch portion of developing cell mobile, to open or close the powder inlet of developing cell.This requires opening powder box
The powder inlet of Delevoping cartridge is opened while meal outlet, therefore it is required that gear teeth 1022, switch portion 105, development switch portion etc. are each
The dimensional accuracy cooperated between component is very high, and the meal outlet of powder box and entering for developing cell are accurately opened when being just able to achieve rotation
Powder mouth.
In addition, being additionally provided with lid 103 outside lid 102, the protruding portion of lid 103 covers on lid 102, and protruding portion is prominent to switch

Referring to Fig. 3 to Fig. 6, developing cell is provided in imaging device, developing cell has abutting part 41, development switch portion
43 and for lock development switch portion 43 locking member 42.Development switch portion 43 has for engaging with the first teeth portion 13
Second teeth portion 432, development switch portion 43 are used to open or close the powder inlet of developing cell.Abutting part 41 is that setting goes out in powder box
Protrusion 14 near powder mouth 12 prevents gate 21 from rotating for abutting the gate 21 of powder box.The middle part of locking member 42 has prominent
421 are played, the one end of locking member 42 has protrusion 422, and the bottom of development switch portion 43 has recess portion 431, do not pacify powder box
Dress in an imaging device when, protrusion 422 is located in recess portion 431, therefore, so that the switch portion 43 that prevents from developing is from closed position to beating
Open position is mobile.
The method for opening the meal outlet 12 of the powder box of the present embodiment includes the following steps.
Firstly, by the installation cavity body of powder box insertion imaging device.
Then, it using the axis of cylindrical part 11 as center axis (in such as Fig. 5 arrow R to) rotation box body 1 clockwise, abuts
Portion 41 is abutted with forced section 212, and gate 21 is fixed relative to imaging device, one of at least meal outlet 12 after cylindrical part 11 rotates
Divide, torsional spring 22 stress torsion corresponding with communication port 214.
Meanwhile with the rotation of the first teeth portion 13, protrusion 14 is first contacted with the protrusion 421 of locking member 42, locking member
After the bending of 42 stress, the end for the protrusion 422 having in locking member 42 is moved down, as shown in fig. 6, protrusion 422 is from recess portion
It is detached from 431, the locking of 42 pairs of component development switch portions 43 at this point, protrusion 14 unlocks.
Then, the first teeth portion 13 is engaged with the second teeth portion 432, is applied when the first teeth portion 13 rotates to development switch portion 43 and is made
Firmly, move development switch portion 43 to shown direction along arrow A in Fig. 6, development switch portion 43 opens powder inlet.To make
Obtain meal outlet 12, communication port 214 is connected to powder inlet.
The method for closing the meal outlet 12 of the powder box of the present embodiment includes the following steps.
Firstly, using the axis of cylindrical part 11 as reversed (i.e. counterclockwise) the rotation box body 1 of center axis, the first teeth portion 13 to
Switch portion 43 of developing applies active force, and development switch portion 43 closes powder inlet.
Then, protrusion 14 is separated with locking member, and the protrusion 422 in locking member 42 enters the recess portion of development switch portion 43
In 431, the locking development switch portion 43 of locking member 42.
Meanwhile gate 21 rotates under the action of 22 elastic restoring force of torsional spring, until meal outlet is fully sealed in sealing 213
12, abutting part 41 is gradually separated with forced section 212.
Finally, powder box is taken out from imaging device.
Therefore after powder box is installed to imaging device, box body is rotated by center axis of the axis of cylindrical part, due to lock
Forced section on door is abutted with abutting part of the developing cell near powder box meal outlet, and gate does not occur relative to imaging device
Rotation, the meal outlet of powder box, communication port are corresponding.Meanwhile protrusion unlock component to development switch portion locking, the first tooth
Portion applies active force to development switch portion, and development switch portion opens powder inlet, and the carbon dust in powder box is after meal outlet, communication port
Enter inside developing cell from powder inlet.In this way, avoiding the powder feeding effect to powder box from generating shadow without the switch portion in cylindrical part
It rings.The driving structure for opening gate can be opened simultaneously with the driving structure for opening developing cell without precisely cooperation, manufacture work
Skill is simpler, and production cost is lower, and can guarantee the stability of powder feeding, to guarantee print quality.In addition, this is practical new
Compared with the existing technology, components are less for the powder box of type, can be effectively reduced cost.
Finally it is emphasized that the above is only the preferred embodiment of the present invention, it is not limited to this reality
With novel, for those skilled in the art, the utility model can have various change and change, all in the utility model
Spirit and principle within, any modification, equivalent substitution, improvement and etc. done should be included in the protection model of the utility model
Within enclosing.
