Technical Field

[0001] The utility model relates to the technical field of printing equipment, in particular to a processing box and a printing equipment using the processing box. Background Art

[0002] Printers are essential equipment in people's daily office life, among which A3 printers are the main office equipment, with the advantages of long life and large printing volume. A3 printers use a powder cartridge to supply toner to the processing box. When the toner in the processing box is used up, the user can replace the powder cartridge separately, which is more environmentally friendly and more economical. A pipe is provided between the powder cartridge and the processing box for powder delivery. The processing box is generally composed of a drum assembly and a developing assembly. The pipes are respectively connected to the powder outlet of the powder cartridge and the powder inlet provided on the drum assembly. Since the drum assembly and the developing assembly are relatively movable installation methods, a hose is used for the pipe. The hose in the prior art is too bent, which makes the toner delivery not smooth, and also takes up space for other components, for example, resulting in the capacity design of the powder cartridge and the waste toner cartridge being too small. Summary of the Invention

[0003] In order to solve the above problem, the utility model provides a processing box to solve the problem of unsmooth flow of carbon powder.

[0020] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0021] like Figure 1As shown, in order to better illustrate the processing box 1, an XYZ three-dimensional rectangular coordinate system is established, wherein the X-axis direction is the length direction of the processing box 1, which is also the installation direction of the processing box 1, the Y-axis direction is the width direction of the processing box 1, the plane formed by the X-axis and the Y-axis is the installation surface of the processing box 1, the Z-axis direction is the height direction of the processing box 1, the +Z-axis direction is also the "top" of the processing box, and the -Z-axis direction is the "bottom" of the processing box.

[0022] like Figures 1 to 3 A processing box 1 is shown, which can be detachably installed inside a printing device, and includes a drum assembly 11 and a developing assembly 12. The two assemblies are assembled by hinged connection and can swing relatively to each other in a small range. It also includes a connecting pipe 13, which is preferably made of a hose, such as a corrugated hose. The connecting pipe 13 is provided with a powder inlet 131 and a powder outlet 132. The powder outlet 132 is connected to the developing assembly 12, and the powder inlet 131 is connected to the toner output port of the printing device. When viewed from the direction in which the processing box 1 is installed on the printing device, the line A connecting the center of the powder inlet 131 and the center of the powder outlet 132 forms an angle with the mounting surface of the processing box 1 on the printing device, as shown in FIG. Figure 3 As shown, line B is a virtual line perpendicular to the installation surface of the processing box 1, and line A and line B form an angle α, and 0°≤α≤15°. This angle is conducive to the natural falling of carbon powder into the developing component 12, avoiding powder blockage in the connecting tube 13, and is also more conducive to the miniaturization of the processing box 1 without occupying the space of other components.

[0023] The powder inlet 131 of the connecting tube 13 can be directly connected to the printing device to receive toner from the powder cartridge (not shown). However, in order to facilitate the disassembly of the process cartridge 1, the connecting tube 13 can be disassembled together with the process cartridge 1 to facilitate operation and avoid powder leakage. The utility model provides a boss 111 on the drum assembly 11. Figure 1 and Figure 3 As shown, the powder inlet 131 is installed on the boss 111. The center of the boss 111 is a through hole connected to the powder inlet 131. When the process cartridge 1 is installed inside the printing device, the boss 111 receives toner from the powder cylinder.

[0024] After the toner is fed into the developing assembly 12, the drum assembly 11 cooperates to perform the printing imaging operation, and the toner is transferred to the paper. This is the existing technology and will not be described in detail. However, some waste toner will not be transferred to the paper. Therefore, a waste toner outlet 112 is provided on the drum assembly 11 for discharging the waste toner.

[0025] In order to facilitate the discharge of waste toner and the installation of the waste toner bin, the present invention has designed the layout of the waste toner outlet 112. Figure 4As shown, when viewed perpendicular to the direction in which the process cartridge 1 is mounted on the printing apparatus, i.e., along the Y-axis, and in the direction perpendicular to the length of the cartridge (the Z-axis), the waste toner outlet 112 is located between the powder inlet 131 and the powder outlet 132. Furthermore, when viewed perpendicular to the mounting direction of the process cartridge 1, the waste toner outlet 112 is located further away from the process cartridge 1 than the powder inlet 131 or the powder outlet 132, facilitating installation of the waste toner bin 14 and increasing the designed capacity of the waste toner bin 14.

[0026] Furthermore, the waste toner bin 14 is detachably mounted to the end of the process cartridge 1, and the waste toner outlet 112 is insertable into the interior of the waste toner bin 14. The waste toner bin 14 has a chamber for accommodating waste toner, comprising a first chamber 141 and a second chamber 142 that communicate with each other. When viewed perpendicular to the installation direction of the process cartridge 1, the first chamber 141 does not overlap with the powder outlet 132 or the powder inlet 131. However, the second chamber 142 partially overlaps with the powder outlet 132 and the powder inlet 131. This allows the chamber of the waste toner bin 14 to be as large as possible, eliminating the need for the user to frequently replace the waste toner bin 14 due to a full waste toner, which would force printing operations to stop.

[0027] Although the embodiments disclosed in the present invention are as described above, the contents are merely embodiments adopted to facilitate understanding of the technical solutions of the present invention and are not intended to limit the present invention. Any person skilled in the art of the present invention may make any modifications and changes in the form and details of the implementation without departing from the spirit and scope disclosed in the present invention. However, the scope of patent protection of the present invention shall still be based on the scope defined by the attached claims.
