[0002] At present, printing equipment is widely used in offices and homes, and has at least one of the functions of printing, scanning, copying, faxing, etc. Among them, there is a printer that uses electronic imaging technology to print images.

[0003] For consumers, imaging quality has always been a focus of attention. In the process of the developing roller transferring the toner, it is affected by the charge of the electrostatic latent image of the photosensitive drum and transfers the charge to the inside of the developing box, so that the toner is stained with the same electrical properties as the electrostatic latent image of the photosensitive drum, resulting in the toner being unable to be transferred to the photosensitive drum due to the same electrical polarity.

[0037] The following will describe the implementation methods of the present invention in detail in combination with the accompanying drawings and embodiments, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. It should be noted that these specific descriptions are only for ordinary technicians in this field to understand the present invention more easily and clearly, rather than a restrictive interpretation of the present invention; for example, the first and second mentioned in the embodiments of the present invention do not constitute a limitation thereto, but are only for expressing the serial numbers of multiple identical or similar devices and mechanisms. Ordinary technicians in this field can also readjust these serial numbers for the convenience of expression or in the process of arranging technical solutions; and alternative solutions are described for some mechanisms in different embodiments, and these alternatives can also be applied to other identical or similar devices and mechanisms; and as long as there is no conflict, the various embodiments in the present invention and the various features in each embodiment can be combined with each other, and the technical solutions formed are all within the protection scope of the present invention.

[0038] The technical solution of the present invention is described in detail below through the accompanying drawings and specific embodiments.

[0039] First, the present invention provides an image forming device, referring to Figure 1 , including a device body 10 and a paper box 11, a paper feeding component 12, a conveying component 13, a developing component 14, an optical scanning component 15, a transfer component 16, a fixing component 17 and a paper discharge component 18 arranged in the device body 10, the paper box 11 stores printing media, after the paper feeding component 12 picks up the printing media from the paper box 11, the conveying component 13 is used to first transfer the printing media to the transfer component 16, the optical scanning component 15 forms an image on the developing component 14, the transfer component 16 transfers the image to the printing medium, and then the conveying component 13 further conveys the printing medium to the fixing component 17, and after the fixing component 17 is fixed, it is discharged to the outside of the device body 10 through the paper discharge component 18.

[0040] The printing medium can be a recording medium such as paper or sheet material that can be used for printing, and is stored in a stacked state in the paper box 11. The paper feeding assembly 12 includes a paper feeding roller and a paper feeding driving mechanism connected to the paper feeding roller. The paper feeding roller is arranged above the stacked printing medium. Under the action of the paper feeding driving mechanism, the paper feeding roller abuts against the top printing medium in the stack. The paper feeding roller feeds the printing medium into the conveying channel of the conveying assembly 13. The conveying channel passes through the transfer assembly 16, the fixing assembly 17 and the paper discharge assembly 18. A conveying roller and a correction roller for moving the printing medium are arranged in the conveying channel. The correction roller is used to calibrate the position of the printing medium in the conveying channel so that the printing medium is in a correct posture during transfer and fixing. The optical scanning assembly 15 includes a laser unit and an optical assembly. After the laser unit emits a light beam, the light beam is transferred to the developing assembly 14 through the optical assembly, so that an image formed by toner for printing is formed inside the developing assembly 14.

[0041] like Figures 2 to 11 As shown, the present invention further provides a colorant box, which is arranged in the developing component 14 of the image forming device, and is used to provide colorant to the image forming device, including a box body 100, a developing member 200, a powder feeding member, a stirring member 300, a photosensitive member, a charging member and a driving member 400. The box body 100 includes a shell, and the interior of the shell has a cavity 110 for storing colorant and a supply port 120 connected to the cavity 110. The colorant in the cavity 110 is output to the outside of the cavity 110 through the supply port 120. The developing member 200 is arranged on the supply port 120 and is located on the inner side of the cavity 110, and contacts the colorant in the cavity 110 to supply the colorant to the outer side of the supply port 120. The powder feeding member is arranged in the cavity 110 and contacts the developing member 200, and is used to transfer the colorant to the developing member 200. The photosensitive member is arranged at the outer position of the supply port 120, and is in contact with the outer surface of the developing member 200. The outer surface of the photosensitive member is a photosensitive surface made of a photosensitive material. When fully charged, it can form an electrostatic latent image under the irradiation of a light beam. The charging member abuts against the photosensitive surface of the photosensitive member and is located at the upstream position of the developing member 200 in the rotation direction of the photosensitive member, so that the photosensitive member passes through the charging member first and then passes through the developing member 200 during rotation. The charging member is used to fill the charge on the photosensitive surface of the photosensitive member. The light scanning assembly 15 emits a light beam to the position between the charging member and the developing member 200, so that the charge is converted into the required electrostatic latent image. The toner on the surface of the developing member 200 is transferred to the photosensitive surface in the contact position with the photosensitive member, and an image composed of the toner is formed under the attraction of the charge on the electrostatic latent image.

[0042] The stirring member 300 is disposed in the cavity 110, located at the center of the cavity 110, and includes a rod body 310 and a conductive blade 320 disposed on the rod body 310. The conductive blade 320 extends from the axis of the rod body 310 toward the inner wall of the cavity 110, and the extended portion can abut against the inner side surface of the cavity 110 that is closest to the rod body 310 except for the side walls installed on both sides, or the shortest distance between the extended portion and the inner side surface of the cavity 110 that is closest to the rod body 310 except for the side walls installed on both sides during rotation is less than 3 mm, and the inner side surface corresponding to the shortest distance is the bottom surface of the toner box in the direction of gravity when the toner box is installed inside the image forming device, so that the trajectory projection of the conductive blade 320 on the plane perpendicular to the axial direction during rotation can cover the cross section of the cavity 110, so that the stirring member 300 can fully stir the stored toner in the cavity 110. At the same time, the rotation direction of the stirring member 300 in the cavity 110 is toward the developing member 200, for example, see Figure 2 The developing member 200 is arranged on the left side of the stirring member 300. When the stirring member 300 rotates toward the developing member 200, that is, rotates in the clockwise direction, the colorant is pushed onto the developing member 200, so that the outer surface of the developing member 200 is fully in contact with the colorant, and a uniform colorant layer is formed.

[0043] In addition, the driving component 400 includes a transmission gear group and a driving gear meshed with the transmission gear group. The driving gear is used to receive the driving force on the image forming device and transmit the driving force to the transmission gear group. Then the transmission gear assembly drives the developing component 200, the photosensitive component and the stirring component 300 to rotate and perform the imaging process.

[0044] In some embodiments of the present invention, the rod body 310 is evenly provided with a plurality of conductive electrodes 311 along its axis direction, each conductive electrode 311 protrudes toward the outside of the rod body 310 perpendicular to the axis, and the conductive blade 320 has a conductive groove 321 that is engaged with the conductive electrode 311. The charge on the toner is eliminated by the connection and cooperation between the conductive blade 320 and the conductive groove 321, and by the contact between the conductive blade 320 and the toner to transfer the charge. Among them, the conductive blade 320 can be detachably connected to the rod body 310. Such a configuration is conducive to the assembly of the stirring member 300, so that the conductive structure inside the stirring member 300 can fully implement the charge guiding effect, and due to the concave-convex cooperation between the conductive groove 321 and the conductive electrode 311, the electrical connection structure between the rod body 310 and the conductive blade 320 can be hidden in the internal structure of the stirring member 300, avoiding the internal conductive material from being exposed in the external cavity 110, resulting in the toner sticking to the internal conductive material to affect the on-off of the conductive circuit.

[0045] Furthermore, the conductive blades 320 are arranged parallel to and tilted along the axis of the rod body 310, and the conductive blades 320 have conductive slopes, and the angle between the conductive slopes and the axis can be set to 30-75 degrees, thereby increasing the contact area between the conductive blades 320 and the toner, and the conductive slopes are located at an upstream position in the rotation direction of the stirring member 300 when the stirring member 300 rotates, so that the conductive slopes of the stirring member 300 contact the toner as the first stirring action surface when the stirring member 300 rotates, and transfer charges in the process, for example, Figure 5 When the conductive blade 320 rotates in the clockwise direction, the conductive blade 320 has an action surface at the front end of the rotation direction and a back surface at the rear end of the rotation direction. The conductive inclined surface is the action surface, which improves the conductive contact effect between the conductive blade 320 and the colorant.

[0046] In one specific embodiment, see Fig.11 The edge position of the conductive blade 320 is set as a conductive edge 322, and the internal structure outside the conductive edge 322 is set as a non-conductive surface made of insulating material, which can reduce the conductive contact area between the conductive blade 320 and the toner while ensuring that the conductive structure of the conductive blade 320 is fully in contact with the toner. Figure 3 In the figure, the conductive edge 322 is set to an arc shape at the extended end of the conductive blade 320 away from the rod body 310. The arc forms a cylindrical surface surrounding the rod body 310 during the rotation of the stirring member 300, and between two adjacent conductive blades 320, the cylindrical surfaces formed by the two conductive edges 322 are connected or partially overlapped in the axial direction of the rod body 310, so that during the stirring process of the stirring member 300, the conductive edge 322 can contact all colorants in the axial direction to avoid uneven charge transfer of some colorants.

[0047] In one embodiment, the rod body 310 includes an axial conductive part 314 and a first component 312 and a second component 313 assembled with each other. The axial conductive part 314 is located between the assembly positions of the first component 312 and the second component 313 and is sealed and wrapped by the first component 312 and the second component 313. Each conductive electrode 311 is electrically connected to the axial conductive part 314. The axial conductive part 314 is hidden inside the rod body 310 to avoid contact with external colorant and affect the conductive effect. The assembly of the first component 312, the second component 313 and the axial conductive part 314 facilitates the assembly of the rod body 310 and reduces the production cost.

[0048] Specifically, the first component 312 is provided with a receiving groove 3121, the axial conductive member 314 is embedded in the receiving groove 3121, and the second component 313 has a sealing protrusion 3131 for sealing the receiving groove 3121. The solute groove is provided on the assembly surface of the first component 312 connected to the second component 313, wherein the first component 312 and the second component 313 are connected together by a snap connection or a screw connection, see Figure 4 The sealing protrusion 3131 is stepped, having a first level 3131a and a second level 3131b, and the receiving groove 3121 is arranged at a wide groove wider than the groove bottom width at its groove position, wherein the first level 3131a is used to be embedded in the receiving groove 3121, and is used to seal and fix the axial conductive member 314 in the receiving groove 3121, and the second level 3131b is further embedded in the wide groove, so that the axial conductive member 314 is fully sealed inside the rod body 310.

[0049] In another embodiment, the box body 100 is provided with a first electrode sheet 130 and a second electrode sheet 140 electrically connected to the external circuit. The first electrode sheet 130 is arranged on the side of the box body 100 containing the driving component 400, and the second electrode sheet is arranged on the other side of the box body 100 not containing the driving component 400, and is electrically connected to the axial conductive member 314 in the rod body 310 through the first electrode sheet 130 and the second electrode sheet 140.

[0050] Among them, the box body 100 is provided with a first gear 410 electrically connected to the first electrode sheet 130 on one side containing the first driving component 400, and a counting gear 430 and a second gear 420 meshing with the counting gear 430 are provided on the other side. The second gear 420 is electrically connected to the second electrode sheet 140. The first gear 410 has a first conductive end 411 that passes through the box body 100 to reach the cavity 110 and is inserted into one end of the rod body 310. The second gear 420 has a second conductive end 421 that passes through the box body 100 to reach the cavity 110 and is inserted into the other end of the rod body 310. The first conductive end 411 and the second conductive end 421 are both in electrical contact with the axial conductive member 314. The first conductive end 411 can be set as a shaft end made of conductive material, on which a protruding first buckle is provided, and the second conductive end 421 can also be set as a shaft end made of conductive material, on which a protruding second buckle is provided, and the gear parts on the first gear 410 and the second gear 420 are respectively mounted on the first conductive end 411 and the second conductive end 421 through keys, and the two sides of the box body 100 are provided with a coaxial first through hole and a second through hole, and the first conductive end 411 is inserted into one end of the rod body 310 through the first through hole, and the second conductive end 421 is inserted into the other end of the rod body 310 through the second through hole. Through the electrical contact between the first conductive end 411 and the second conductive end 421 and the first electrode sheet 130 and the second electrode sheet 140, the stirring member 300 can make electrical contact with the toner inside the cavity 110 by utilizing the conductive property.

[0051] Can be expanded, see Figure 3 The counting gear 430 is provided with an electric contact portion 431 and a counting action portion 432 electrically connected to the electric contact portion 431. The electric contact portion 431 is electrically connected to the second electrode sheet 140. The counting action portion 432 is made of a conductive material and is used to cooperate with a counting unit outside the image forming device. By conductive means, the counting action portion 432 is electrically contacted with the counting unit of the external image forming device before the counting gear 430 rotates, and the counting signal is transmitted to the counting unit in the form of an electrical signal, which can effectively send the counting information to the counting unit. After the counting gear 430 rotates, the counting action portion 432 is separated from the counting unit, so that the counting unit can know the usage status of the colorant box, or, each time the counting action portion 432 contacts the counting unit, the counting unit calculates the number of rotations of the developing component 200 and / or the sensing component inside the colorant box according to the number of contacts, thereby knowing the usage status of the colorant inside the colorant box.

[0052] Further reading Figures 5 to 9The first end of the stirring member 300 is provided with a first conductive seat 330, and the second end is provided with a second conductive seat 340. The first conductive seat 330 is arranged in a first mounting hole where the first end of the rod body 310 matches with the first conductive end 411, and the second conductive seat 340 is arranged in a second mounting hole where the second end of the rod body 310 matches with the second conductive end 421. The two ends of the axial conductive member 314 are electrically connected to the first conductive seat 330 and the second conductive seat 340 respectively, the first conductive seat 330 contacts and matches with the first conductive end 411, and the second conductive seat 340 contacts and matches with the second conductive end 421. Such an arrangement can ensure smooth conductive contact while maintaining the compactness of the stirring member 300 as a whole.

[0053] In another embodiment, see Figure 7 The rod body 310 is provided with a plurality of slots 315 along the axial direction, and the conductive blade 320 has a snap portion that matches the slot 315. The connecting line between the conductive electrode 311 and the slot 315 is parallel to the conductive inclined surface, so that during the installation of the conductive blade 320, the installation position of the conductive electrode 311 on the conductive blade 320 matches the inclination angle of the conductive blade 320 on the rod body 310, thereby reducing the space occupied by the conductive blade 320.

[0054] Finally, it should be noted that the above description is only the best embodiment of the present invention and does not limit the present invention in any form.
