Description

A kind of electrophotographic imaging forming apparatus powder box

Technical field

The utility model relates to a kind of electrophotographic imaging forming apparatus, as printer, duplicating machine, facsimile recorder etc., particularly a kind of electrophotographic imaging forming apparatus powder box.

Background technology

Common electrophotographic imaging forming apparatus as laser printer, duplicating machine etc., comprising: scanister, developing apparatus, transfer device and fixing device.Wherein, developing apparatus also comprises: the photosensitive drums that is formed with electrostatic latent image thereon; Make the developer roll of latent electrostatic image developing on the photosensitive drums; Make the charging roller of electric charge on the photosensitive drum surface band; Carry carbon dust to give the powder feeding roller of developer roll; Powder box for the developing process supply toner.

For electrophotographic imaging forming apparatus, its employed carbon dust is a kind of consumable material, just must be replaced with new powder box after the powder box with a constant volume uses.

Korean Patent Publication No. KR1020070021848A, open day is on February 23rd, 2007, this application discloses a kind of meal outlet structure of powder box.Be provided with the packoff of a hollow near the inner meal outlet of powder box, its length is greater than the meal outlet width, and have one with the sizable opening of meal outlet, when powder box is not mounted when using, the sealing device seals up the powder box meal outlet, prevents that carbon dust from flowing out; When powder box was mounted use, the sealing device was promoted by the stationary installation in the machine, made the opening of packoff aim at the powder box meal outlet, and carbon dust flows out from meal outlet; When powder box was removed in machine, the sealing device pushed back to sealing state under the effect of flexible member, and this moment, meal outlet was closed, and carbon dust can't flow out from meal outlet.

Fig. 1 is for adopting a kind of powder box of this technology, and powder box comprises: powder tube 40, packoff 80, meal outlet 91 and flexible member 85 in the shell 30 of powder tube one end, powder tube.

Because what this technology adopted is that flexible member 85 promotes packoff 80, makes its sealing power discharging mouth 91, therefore needs to add a shell 30 again at an end of powder tube 40; Packoff 80 is arranged in this shell 30, and can slide in shell 30; One end in contact powder tube 40 of flexible member 85, other end contact sealing device 80 applies an elastic force for packoff 80, makes its answer.Propose unnecessary requirement for like this powder box structure, cause the powder box complex structure.

And the outside dimension of flexible member 85 requires to equate with the internal diameter of cylinder 90 on the shell 30.The external diameter of flexible member 85 rubs the flexible member 85 and the inwall of cylinder 90 than the internal diameter conference of cylinder 90, causes packoff 80 to be difficult to reply; The outside dimension of flexible member 85 flows than the little carbon dust that can hinder of the internal diameter of cylinder 90, causes meal outlet 91 powder sending quantity deficiencies, or flexible member 85 is sticked in the packoff 80 and can't operate as normal.Therefore, strict more to the dimensional requirement of flexible member 85, bring difficulty to the manufacturing.

The utility model content

Technical problem to be solved in the utility model provides a kind of simple in structure, powder box that manufacture difficulty is little.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:

A kind of electrophotographic imaging forming apparatus powder box comprises: a powder tube that is used to hold carbon dust, powder tube sidewall have a meal outlet from carbon dust to developing apparatus that carry; Be stored in the carbon dust in the powder tube; Puddle support in the powder tube; Be installed in the puddle support drive unit of powder tube end; But the sliding members of an art skating in the powder tube can open and close the meal outlet passage as required by sliding of this sliding members; One first magnetic element is arranged on the powder tube; Second magnetic element corresponding with first magnetic element is arranged on the sliding members.

Sliding members described in the utility model can be a hollow cylinder with second meal outlet, and when second meal outlet did not dock with powder tube meal outlet, powder spout was closed; When second meal outlet docked with powder tube meal outlet, powder spout was opened.This sliding members also can be short cylinder slide block, and when sliding members blocked powder tube meal outlet fully, powder spout was closed; When sliding members can not block powder tube meal outlet fully, powder spout was opened.

First, second magnetic element is opposite polarity magnet, from the front end face that cooperates with machine intimate, and first magnetic element of arranging successively, second magnetic element, meal outlet.

First, second magnetic element also can be the identical magnet of polarity, from the front end face that cooperates with machine intimate, and the meal outlet of arranging successively, second magnetic element, first magnetic element.

The utility model has the advantages that:

1. an end of powder tube no longer includes shell, makes the powder box structure become simpler, saves material;

2. do not re-use flexible member, and use magnetic element instead, and magnetic element no longer includes the strict demand on the size, make the manufacturing easier.

Description of drawings

Fig. 1 is a kind of powder box that adopts prior art;

Fig. 2 is a kind of embodiment of the present utility model;

Fig. 3 is the meal outlet place partial enlarged drawing of a kind of embodiment of the utility model.

Embodiment

A kind of powder box as shown in Figure 2 comprises: the powder tube 1 that can hold carbon dust; Be installed in the puddle support 2 in the powder tube 1; The driven wheel 11 of puddle support 2; Also have the first powder feeding element 3 and the second powder feeding element 4 in the powder box, they are transported to first meal outlet 6 with carbon dust; A sliding members 5 is arranged near first meal outlet 6, these sliding members 5 hollows, and can on powder tube 1, slidably reciprocate, can make 6 sealings of first meal outlet or connection; On the front end face of powder tube 1, be fixed with first magnetic element 7; Front end face at sliding members 5 close first magnetic elements 7 is fixed with second magnetic element 8, and they are two blocks of opposite magnet of magnetic, can attract each other.

As shown in Figure 3, be pasted with encapsulant 10 on the sliding members 5,, first meal outlet 6 sealed, prevent that carbon dust from leaking as sponge, felt etc.; On sliding members 5, also be provided with second meal outlet 9.

When powder box is not used, when being original state, first magnetic element 7 and second magnetic element 8 attract each other, sliding members 5 keeps virgin state not slide in the effect of magnetic force, therefore, second meal outlet 9 does not dock with first meal outlet 6, makes first meal outlet 6 keep sealing state, prevents that carbon dust from leaking;

When powder box is mounted use, sliding members 5 is promoted to the right from the left part by the stationary installation in the machine, second meal outlet 9 is docked, at this moment with first meal outlet 6, after carbon dust is transported in the sliding members 5, can flow out by second meal outlet 9 and first meal outlet 6;

When powder box was removed in machine, sliding members 5 slided into original state left under the magneticaction of first magnetic element 7 and second magnetic element 8, and first meal outlet 6 and second meal outlet 9 stagger, and made 6 sealings of first meal outlet.
