Description

Developer box

Technical field

The utility model relates to the printer that is applied in the electrofax mode, and the developer box that uses on the imaging devices such as duplicating machine or facsimile recorder particularly relates to the developer box with cylindrical body structure.

Background technology

In image processing system, using to make easy and simple to handlely always, do not allow developer disperse towards periphery, the tubular developer box of replenishment developer easily, it after the image processing system of packing into, also can be used as the supplementary device of developer except the container as the supplying developing agent uses.

Existing a kind of tubular developer box, it comprises that an inner core and with inner opening has the urceolus of outer opening, wherein inner core accommodates developer, it is rotatable be installed in the urceolus and with its sliding contact.The length of this developer box inner core is greater than urceolus, and the one end is provided with developer and fills mouth, and by a dome seal, the other end is provided with transmission gear, and it is connected with the puddle support that is located at inner core inside by a gland bonnet.Two ends at inner core also are respectively equipped with handle, be respectively applied for the rotary seal inner core, developer box is located in imaging device.By the rotation inner core, the inner opening of inner core is alignd with the outer opening of urceolus, can open inner opening, carry out the discharging of developer; The outer opening of the inner opening of inner core and urceolus staggers, and can close inner opening, stops the discharging of developer.

Developer box with said structure is made of inside and outside double tubular body, and part is too much, and cost of manufacture is higher.When installation is used, need the rotation inner core, the moment of torsion that is produced is bigger, and operation is inconvenient.In addition, developer box in use, inner core rotation can make developer drop to the urceolus from inner opening, is deposited in outer opening position, causes the developer leakage when taking out developer box.

Summary of the invention

The purpose of this utility model provides a kind of novel developer box that solves the problems of the technologies described above, and it does not establish inner core, and developer directly is stored in the urceolus.

For achieving the above object, the utility model provides following technical scheme: developer box comprises: the cylindrical body of accommodating developer; The meal outlet of opening on the cylindrical body circumferential wall; Be located at the puddle support that cylindrical body is inner and can rotate freely; Be installed in the sealing handle of cylindrical body one end; Wherein, the sealing handle has hermetic unit and grip, and hermetic unit is tubular, has on its circumferential wall and the corresponding opening of meal outlet, by the rotary seal handle, can open or close meal outlet.

Developer box with said structure has only one deck cylindrical body, and structure is simple relatively, and manufacturing cost is lower; By the short sealing handle opening/closing meal outlet of rotation length, moment of torsion is less relatively, and is easy to operate.In addition, what the meal outlet of developer box was aimed at imaging device always connects powder mouth position, can not produce developer and be deposited in the meal outlet position and cause leakage powder.

Better scheme is that developer box also comprises the sealing cap of being located at cylindrical body one end, by sealing cap and the joining transmission gear of puddle support.

Developer box with said structure can drive puddle support and rotate, thereby stir the developer that stores in cylindrical body by the cooperating of transmission gear and imaging device.

Better scheme is that developer box further comprises: extraction mechanism, to be located on the outer circle wall of cylindrical body, and it comprises a straight portion and a sloping portion.

Developer box with said structure, because of extraction mechanism is provided with straight portion, convenient when the operator extracts developer box, comfortable.

Description of drawings

Fig. 1 is the assembling synoptic diagram of the utility model developer box;

Fig. 2 is the structural drawing of the utility model developer box;

Fig. 3 is the upward view of the utility model developer box;

Fig. 4 is the A-A cut-open view of Fig. 2.

Below in conjunction with accompanying drawing developer box of the present utility model is described in detail.

Embodiment

Referring to Fig. 1, Fig. 2, developer box 1 comprises the elongated cylindrical body 2 of accommodating developer, it has both

ends

21 and 22, be located at the meal outlet 3 on cylindrical body 2 circumferential wall, be located at the puddle support 4 that cylindrical body 2 inside can rotate freely, be rotatably installed in the end 21 of cylindrical body 2, to seal the sealing handle 5 of this end opening.

Sealing handle 5 comprises a grip 51 and a hermetic unit 52, and wherein hermetic unit 52 is cylindric, and circumferential wall is provided with and meal outlet 3 corresponding slotted openings 53, and the length of hermetic unit 52 should guarantee its salable meal outlet 3.The operator is by holding grip 51 rotatable sealing handles 5, the slotted opening 53 of hermetic unit 52 is alignd with meal outlet 3 or staggers, and can open or close meal outlet 3.For reducing the length of hermetic unit 52, meal outlet 3 can be as much as possible be provided with near an end 21 of cylindrical body 2.

Also be provided with sealing cap 6 and transmission gear 7 in the end 21 of cylindrical body 2, puddle support 4 can link together with transmission gear 7 by sealing cap 6.On the circumferential wall of hermetic unit 52 corresponding to the position of transmission gear 7, be provided with slit 71, by this, transmission gear 7 can be driven by the drive unit on the imaging device, and then drive puddle support 4 rotates together, the developer that is stored in the cylindrical body 2 is delivered to meal outlet 3 places, simultaneously the developer in the cylindrical body 2 is stirred.

Puddle support 4 is spiral in the present embodiment, and by the wire rod of stainless steel or iron, the external diameter in accordance with regulations and the pitch of regulation are made.But also can be the puddle support of disclosed other form in the prior art, as vane type etc.

The hermetic unit 52 of sealing handle 5 can be enclosed within the outside of cylindrical body 2, also can be inserted into cylindrical body 2 inside.Referring to Fig. 3, Fig. 4, in the present embodiment, hermetic unit 52 is inserted in the cylindrical body 2, and at this moment, transmission gear 7 all is positioned at hermetic unit 52 with sealing cap 6, with sealed handle 5 sealings of an end 21 openings of cylindrical body 2.

In the opposite end of sealing cap 6, the other end 22 openings of cylindrical body 2 form developer and fill mouth 8, and they can be by a dome 9 sealings.

Also be provided with the mechanism 10 of taking on the circumferential wall of cylindrical body 2, it comprises a straight portion 101 and a sloping portion 102, under the situation that mounting condition allows, straight portion 101 can be done height as much as possible and do length, and the person takes with handled easily.

Technical conceive of the present utility model is not limited in the foregoing description, can also draw many different concrete schemes according to design of the present utility model, for example, sealing handle 5 can be filled mouth 8 with developer and is located at same end etc., all should be included within the described scope of claim such as these minor alterations and equivalent transformation.
