Referring to fig. 1, there is shown an exploded perspective view of a powder cartridge provided herein in one embodiment. The powder cartridge comprises a cartridge body 1, an end cover 2 and a tail cover 3. The barrel 1 comprises a material containing cavity (not shown in the figure), a feeding hole 101 and a discharging hole (not shown in the figure). The material accommodating chamber is used for accommodating an image forming material such as developer, and the feed port 101 and the discharge port are respectively located at both ends of the barrel 1. The discharge port is used for outputting imaging materials for printing or copying imaging of the printing equipment. The feeding inlet 101 is used for adding the imaging material to the material containing cavity when the imaging material in the cylinder body 1 is used up, so that the powder cylinder can be continuously used to save cost. End cap 2 is fittingly connected to the discharge port, and end cap 2 is capable of cooperating with a structure in the electrophotographic apparatus to supply the electrophotographic apparatus with imaging material stored in the powder cartridge. The tail cover 3 is connected to the feed inlet 101 in a threaded connection mode to seal the cylinder body 1, and further prevent the imaging material in the material accommodating cavity from leaking. Wherein, barrel 1 still includes spacing arch 102, and spacing arch 102 is located feed inlet 101, and tail-hood 3 includes spacing groove 31, and spacing groove 31 corresponds the setting with spacing arch 102, and both can cooperate spacingly. When the tail cover 3 is connected with the barrel 1, the tail cover 3 is prevented from sliding on the feed port 101 in the axial direction and the radial direction under the condition of not being screwed down through the limit matching of the limit groove 31 and the limit bulge 102, so that the developer in the powder barrel is prevented from leaking, and the work of the electronic imaging device is further influenced.

Specifically, the cartridge 1 further includes a powder cartridge main body 11, a feeding portion 12, and a discharging portion (not shown in the figure), and the feeding portion 12 and the discharging portion are respectively connected to both ends of the powder cartridge main body 11. The material containing cavity is arranged on the powder cylinder main body 11, the feeding hole 101 is arranged on the feeding part 12, and the discharging hole is arranged on the discharging part. This application is through the setting of feeding portion 12 and ejection of compact portion, the end cover 2 and the tail-hood 3 of being more convenient for and being connected of barrel 1.

Further, the outer surface of the feeding portion 12 is provided with a first thread 121, and a limiting protrusion 102 is disposed at one end of the feeding portion 12 close to the powder cartridge main body 11. The inner surface of the tail cover 3 is provided with a second thread 32, and the second thread 32 is matched with the first thread 121, so that the tail cover 3 can be fixedly connected with the feeding part 12 through the first thread 121 and the second thread 32. During the equipment, connect end cover 2 in ejection of compact portion, with tail-hood 3 through first screw thread 121, second screw thread 32 threaded connection in feed portion 12, make spacing arch 102 block in spacing groove 31, and then when making tail-hood 3 and feed portion 12 sealing connection, through the cooperation of spacing arch 102 with spacing groove 31 to prevent that tail-hood 3 from taking place axial and radial slip on feed inlet 101 under the condition of not screwing up, guaranteed the leakproofness that tail-hood 3 and barrel 1 are connected.

Referring to FIG. 2, a perspective view of the tailcap of FIG. 1 in one embodiment is shown. The tail cover 3 further comprises a guide part 34 and a limiting part 33, and the limiting groove 31, the limiting part 33 and the guide part 34 are sequentially arranged along the screwing direction of the tail cover 3 and the feeding part 12. When the tail cap 3 is screwed to the inlet portion 12, the stopper projection 102 can be smoothly fitted into the stopper groove 31 by the guide of the guide portion 34.

Specifically, the guide portion 34 includes a guide notch 341 and a groove 342, and a height H of the guide notch 341 gradually decreases along the screwing direction of the tail cover 3, wherein the height H of the guide notch 341 is a distance from an inner wall of the guide notch 341 to a bottom of the limiting portion 33, as shown in fig. 5. The groove 342 is located at one end of the guiding gap 341 near the limiting portion 33. When the edge of the tail cover 3 is screwed to one end of the feeding part 12 close to the powder barrel main body 11, one end of the limiting protrusion 102, which is far away from the limiting part 33 from the guiding notch 341, relatively moves to one end of the guiding notch 341, which is close to the limiting part 33, and enters the groove 342, the tail cover 3 is continuously screwed, the limiting protrusion 102 abuts against the limiting part 33 and crosses the limiting part 33 to enter the limiting groove 31, and the tail cover 3 is prevented from sliding in the axial direction and the radial direction of the feeding part 12 under the condition of not being screwed down through the matching limitation of the limiting protrusion 102 and the limiting groove 31.

Further, the height of the limiting groove 31 is slightly larger than the height of the limiting protrusion 102, and the width of the limiting groove 31 is slightly larger than the width of the limiting protrusion 102, so that the limiting protrusion 102 and the limiting groove 31 can be better matched to realize limiting.

In order to make the limiting protrusion 102 more smoothly screwed into or out of the limiting groove 31, the outer surface of the limiting protrusion 102 is arc-shaped. Because the arc-shaped stopper projection 102 is more easily screwed into or out of the stopper groove 31 beyond the stopper portion 33.

Referring to fig. 3 and 4, fig. 3 is a perspective assembly view of the powder cartridge provided in the present embodiment; fig. 4 is a partially enlarged view of a powder cartridge provided in an embodiment of the present application. After the imaging material in the powder cartridge is used up, when the tail cover 3 needs to be detached, the tail cover 3 is rotated in the arrow direction in fig. 4, so that the limiting protrusion 102 abuts against the limiting part 33 and goes over the limiting part 33 to enter the groove 342, that is, the limiting protrusion 102 is separated from the restriction of the limiting groove 31. Continuing to rotate the tail cover 3 along the arrow direction in fig. 4, the limiting protrusion 102 rotates along the guiding notch 341 and the tail cover 3 relatively, and finally the tail cover 3 can be separated from the feeding portion 12, so as to open the tail cover 3. At this time, the imaging material may be added to the material containing chamber through the material inlet 101. After the image material is added, the tail cap 3 is screwed to the feeding portion 12 in the direction opposite to the arrow in fig. 4, so that the tail cap 3 is rotated along the first screw 121. When the edge of tail-hood 3 is close to the one end that feed portion 12 is close to powder section of thick bamboo main part 11 gradually, guide breach 341 guide tail-hood 3's installation has dodged and has set up in the spacing arch 102 at feed portion 12, thereby the butt of the edge of tail-hood 3 to spacing arch 102 has been avoided, spacing 33 contact spacing arch 102, spacing arch 102 is to spacing 33 application extrusion force crowded spacing portion 33 entering spacing groove 31 in, the joint location of tail-hood 3 and feed portion 12 has been realized, thereby prevent that tail-hood 3 is not hard up, the sealing performance of a powder section of thick bamboo has been strengthened, guarantee imaging device's normal work.

The above description is only for the preferred embodiment of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present application should be covered within the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
