Abstract

A carbon puff box relates to a recharging carbon powder device for developing mechanism of electrophotography picture, in particular to the carbon puff box for recharging carbon powder of a duplicator, a facsimile machine, a printer, which includes a cylindrical outer cylinder, a stripy out-powder port being arranged along a shaft, and an inner cylinder relative rotating to the outer cylinder being arranged in the outer cylinder. The inner cylinder accommodates carbon powder inside, whose one end provides a dynamic received part. The inner cylinder wall provides a stripy supply-powder port corresponding to the outer cylinder wall, and a pushing powder inclined plane. Around the outer surface of the inner cylinder fixing a seal, one long edge of the stripy sealing film is fixed on the outer surface of the inner cylinder supply-powder port, and the sealing film elastically covers the largest curved surface being formed by the seal. The inner cylinder is good rigidity, no deformation in the manufacturing and using process, reliable supplying powder and the extremely low amount of residual powder.

Description

Cartridge

Technical field

It is the device of the developing mechanism supply carbon dust of electrophotographic image that the utility model relates to a kind of, particularly supplies with the cartridge of carbon dust to duplicating machine, facsimile recorder, printer etc.

Background technology

Existing cartridge is a cylindrical body, in fill carbon dust, also have a puddle support that has the power receiving portion.After the cartridge installation, the strip powder supply port on the box body is in open mode, and puddle support scrapes supply equipment with carbon dust in rotating process.Utilize the rotary power of puddle support to be difficult to powder is all scraped, in addition, because puddle support is axially having bigger size, deform in making and using unavoidably, product percent of pass is reduced, residual powder is too much.

Summary of the invention

The purpose of this utility model provides the less cartridge of a kind of powder rational in infrastructure, residual.

For this reason, the cartridge that the utility model provides comprises a columniform urceolus, barrel has a strip meal outlet of arranging vertically, be built-in with an inner core of its rotation relatively at urceolus, the inside of inner core holds carbon dust, inner core one end has a power receiving portion, and inner tube wall is provided with and the corresponding strip powder supply port of outer tube wall.One week of inner tank theca powder supply port is fixed with seal, and a long limit of strip sealed film is fixed on the outer wall at inner core powder supply port place, and sealed film is flexibly topped on the maximum curved surface that seal forms.When meal outlet and powder supply port staggered, sealed film was pressed on the seal by outer tube inner wall, and the carbon dust in the inner core can not drop out; When inner core turns to meal outlet when overlapping with powder supply port, sealed film is by the elasticity of self, make loose another long limit break away from seal, promptly opened powder spout, carbon dust in the inner core has fed to machine, inner core is rotated further sealed film and is compressed the sealing powder supply port by outer tube inner wall again, and like this, a certain specific powder supply port supplies powder once to meal outlet when inner core rotates a week.Owing to adopted core structure in the better rigidity, all can not deform in manufacturing and the use, reliable for powder, residual powder amount is extremely low.

Be further to improve for the powder reliability, also can the lagging edge setting of powder supply port stretch to guide margin and in tube, tilt push away the powder inclined-plane.For improving continuity for powder, can many powder supply ports be set at inner core, like this, inner core circles and can repeatedly supply powder to meal outlet.For further reducing residual powder amount, be fixed with in the end of urceolus and push away powder spare, pushing away powder spare has the scraper that stretches into inner core and have helicoid, makes the carbon dust that is in the inner core end be driven to the powder supply port at middle part.

Fig. 1 is the most preferred embodiment stereographic map;

Fig. 2 is the STRUCTURE DECOMPOSITION figure of most preferred embodiment;

Fig. 3 is the middle longitudinal section of most preferred embodiment;

Fig. 4 is the A-A cut-open view of Fig. 3.

Be described in further detail below in conjunction with most preferred embodiment of the present utility model and accompanying drawing thereof.

Embodiment

Referring to Fig. 1, the urceolus 10 of cartridge has a meal outlet 11 vertically, and the opening end of urceolus 10 fastens by button bit 12 and lid 30.

Referring to Fig. 2, this routine urceolus 10 has a meal outlet 11, opening end has symmetrically arranged two button bits 12, lid 30 has a pressure head 31, the opening end of inner core 20 is stamped one and pushes away powder spare 50, and pushing away powder spare 50 has two scrapers 51 that have helicoid that stretch into inner core, is used for pushing the carbon dust of inner core 20 opening ends to powder supply port 22, pushing away powder spare 50 has an axle bed 52, and the tight cover of capping 40 with s function is fixed on and covers on the inner 31 of 30.Inner core 20 has two powder supply ports 22 corresponding with meal outlet 11, and every powder supply port 22 is continuous vertically, if tube is very long, also powder supply port 22 can be designed to axially be interrupted, to improve the rigidity of inner core.Inner core 20 rotates by the diagram A direction of arrow relative to urceolus 10, is provided with at the lagging edge of powder supply port 22 and pushes away powder inclined-plane 21.Week at each powder supply port 22 is stained with rubber seal 23, is stained with elasticity better seal film 24 at the guide margin of powder supply port 22, and sealed film 24 can be pressed in sealing powder supply port 22 on the seal.Powder supply port 22 length in the axial direction slightly is shorter than meal outlet 11, and like this, when a low-angle was missed in two salty merging, freely growing the limit and can flicking of sealed film 24 made carbon dust enter machine by two mouths.The other end of inner core 20 has a power receiving portion 25, and it also is an axle, passes the axis hole on urceolus 10 other ends, accepts the power of machine and inner core is rotated.

Referring to Fig. 3, in the inner core chamber 26 carbon dust is housed.

Referring to Fig. 4, for say something clear for the purpose of, this figure is amplified, inner core turns to powder supply port and meal outlet when missing a low-angle along the diagram B direction of arrow relative urceolus, sealed film freely grow the constraint that the limit can lose outer tube inner wall, rely on the elasticity of self to stretch, thereby make the interior carbon dust of inner core under the effect that pushes away powder inclined-plane 21, along diagram C direction of arrow supply equipment.
