Description

Cartridge

Technical field

The utility model relates to the used cartridge of a kind of electrophotographic image forming.

Background technology

Usually have graphics processing unit and developing cell in the electrophotographic image forming, the developers such as carbon dust that utilize developing cell to provide, for the latent electrostatic image developing that forms on the graphics processing unit on media such as paper, to form visual picture.Wherein carbon dust needs constantly in electrophotographic image forming, to replenish as consumables.The cartridge that holds a certain amount of carbon dust that has that general employing removably is mounted in the developing cell provides carbon dust to electrophotographic image forming.

As shown in Figure 1; Existing a kind of cartridge has box body 10; Have the carbon dust accommodation section that holds carbon dust in the box body, the bottom has the meal outlet of discharging carbon dust in the carbon dust accommodation section, has the gate 101 of able to turn on or off meal outlet and the handle 102 that the operation gate makes it to open and close meal outlet on the box body.Have tooth portion 103 on the handle 102, be used for electrophotographic image forming in gear set engagement, be passed to the tooth portion 104 of gate 101 again via gear set.

This kind cartridge can provide driving force through turning handle 102; Meal outlet is opened and is closed in the gear set engagement in the tooth portion 103 that relies on handle 102 and the electrophotographic image forming and the engagement of gear set and gate 101 tooth portions 104; Gate 101 Drive Structure are complicated, and handle 102 rotary resistances are bigger and fragile.The tooth portion 103 of gate 101 and handle 102 all is arranged on the outside of box body 10, receives external impacts easily and damages.In addition, need the mounting teeth wheels in the electrophotographic image forming, not only occupy its inner space but also increase its complexity, and need higher quality of fit and then cost increase.After electrophotographic image forming worked long hours, gear set may occurrence positions changes, thereby brought difficulty for handle 102 operation gates 101 open and close meal outlets, even caused the cartridge can't operate as normal.

Summary of the invention

The purpose of the utility model provides a kind of simple in structure, cartridge that gate can accurately open or close meal outlet.

For realizing above-mentioned purpose, the cartridge that the utility model provides comprises the box body with carbon dust accommodation section; Be arranged on the meal outlet of box body bottom, be used to discharge the carbon dust that the carbon dust accommodation section holds; Be arranged on the gate on the box body, can open or close meal outlet; Be arranged on the handle of box body one end rotationally, have the grip part so that handle rotates; Handle is provided with gear part, and gate is provided with the tooth portion that can receive gear part power.

Through the tooth portion engagement of the gear part that is provided with on the handle and gate, the tooth portion that driving force directly is passed to gate by the gear part of handle is to open and to close meal outlet, and simple in structure, rotary resistance is little.Also need not to be provided with gear set in the electrophotographic image forming, thereby can practice thrift its inner space.The tooth portion of gate be internal tooth with the handle gearing mesh, thereby lock incisor process and handle gear are not vulnerable to external impacts, thereby not fragile.

More concrete scheme is that handle has the plate-like piece that is arranged between grip part and the gear part, and the external diameter of plate-like piece is greater than the maximum outside diameter of gear part; Box body is provided with jut; Plate-like piece is provided with the recess that holds jut; Handle turns to meal outlet when opening or closing two extreme positions, and recess receives the constraint of jut respectively at two end faces that make progress in week.

The plate-like piece of handle is arranged on the outside of gear part can further protect the gear part of handle and the tooth portion of gate, through the cooperate anglec of rotation that limit handle of recess with jut.

Another program that the utility model provides is:

Cartridge comprises the box body with carbon dust accommodation section; Be arranged on the meal outlet of box body bottom, be used to discharge the carbon dust of carbon dust accommodation section; Be arranged on the gate on the box body, can open or close meal outlet; Be arranged on the handle of box body one end rotationally, have the grip part so that handle rotates; Handle is provided with gear part, and box body is provided with the gear part engagement of transition gear and handle, and gate is provided with tooth portion and transition gear engagement.

Through the transition gear engagement that is provided with on the gear part that is provided with on the handle and the box body, the tooth portion of transition gear and gate meshes, and the tooth portion that rotary driving force is passed to gate by the gear part of handle is to open and to close meal outlet, and simple in structure, rotary resistance is little.Also need not to be provided with gear set in the electrophotographic image forming, thereby can practice thrift its inner space.The tooth portion of gate be internal tooth with the transition gear engagement, thereby lock incisor process and handle gear are not vulnerable to external impacts, thereby not fragile.

More concrete scheme is that cartridge has the puddle support that stirs carbon dust accommodation section carbon dust, handle and the coaxial setting of puddle support.Thereby handle is positioned at the approximate centre position of box body end, can make cartridge be easier to balance.

Another more concrete scheme is that handle has the plate-like piece that is arranged between grip part and the gear, and the external diameter of plate-like piece is greater than the maximum outside diameter of gear; Box body is provided with jut; Plate-like piece is provided with the recess that holds jut; Handle turns to meal outlet when opening or closing two extreme positions, and recess receives the constraint of jut respectively at two end faces that make progress in week.

The gear part and the transition gear of handle can be further protected in the outside that the plate-like piece of handle is arranged on gear part, through the cooperate anglec of rotation that limit handle of jut with recess.
