All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

As described in the background art, the image forming apparatus of the related art has a problem of leakage of waste powder, and the inventor has found that the problem arises because the image forming apparatus of the related art includes a process cartridge and a waste powder cartridge including a cartridge body provided with a waste powder port and a sealing sponge having a slit therein, the sealing sponge being shielded from the waste powder port. The process cartridge includes a cartridge body having a waste toner hopper and a toner discharge tube, residual toner remaining on the photoreceptor is removed by a cleaning device, and the removed residual toner is collected as waste toner in the waste toner hopper. The powder discharge pipe is propped up to open a notch on the sealing sponge, then penetrates through the waste powder port and extends into the cylinder body so as to discharge waste powder in the waste powder bin into the waste powder cylinder. However, since the end of the powder discharge tube is sharp, the powder discharge tube easily causes the breakage of the sealing sponge when the sealing sponge is pushed up, and thus the sealability between the waste powder port and the powder discharge tube is lowered, resulting in leakage of waste powder in the waste powder cylinder from the waste powder port.

To above-mentioned technical problem, this application embodiment provides a processing box and image forming equipment, through setting up the direction inclined plane in the one end that deviates from the useless powder storehouse of arranging the powder pipe, the distance between the axis of direction inclined plane and row powder pipe is by deviating from the one end in useless powder storehouse to the one end that is close to useless powder storehouse increase gradually, can reduce the sharp degree that arranges the powder pipe end like this, makes row powder pipe be difficult for the top to break seal sponge when stretching into useless powder section of thick bamboo, seal sponge seals between useless powder section of thick bamboo and the seal sleeve to effectively avoid useless powder leakage.

The principles and features of embodiments of the present application are described below with reference to the drawings, the examples being provided for the purpose of illustrating the embodiments of the present application and not for the purpose of limiting the scope of the embodiments of the present application.

Referring to fig. 1 and 2, the present embodiment provides an image forming apparatus including a waste toner cartridge including a cartridge body 210 and a flexible sealing member 220, and a process cartridge, the cartridge body 210 being provided with a waste toner opening 211. The flexible sealing member 220 may be a sponge member, a flannelette member, a rubber member, or the like, the flexible sealing member 220 may be a flat plate structure, and a plurality of intersecting slits 221 are provided on the flexible sealing member 220, so that the plurality of slits 221 are opened under the pushing of the external force to form a sealing port, the flexible sealing member 220 is disposed on the outer side of the cylinder 210, and the flexible sealing member 220 shields the waste powder port 211, so that the waste powder in the cylinder 210 is not easy to leak from the waste powder port 211.

Referring to fig. 1, 3 and 4, the process cartridge includes a cartridge body 110 and a toner discharge port assembly 120, the cartridge body 110 having a waste toner hopper 111 therein, the waste toner hopper 111 being for collecting residual toner removed from a photosensitive body, hereinafter, the residual toner removed from the photosensitive body will be referred to as waste toner.

The powder discharge port assembly 120 comprises a powder discharge tube 121 and a sealing sleeve 122, one end of the powder discharge tube 121 is communicated with the outlet of the waste powder bin 111, the other end of the powder discharge tube 121 is sealed, a powder discharge port 1211 is formed in the side wall of one end, facing away from the waste powder bin 111, of the powder discharge tube 121, and waste powder in the waste powder bin 111 can be transmitted to the powder discharge port 1211 through the powder discharge tube 121.

The sealing sleeve 122 is sleeved outside the powder discharge pipe 121, and the sealing sleeve 122 is connected with the powder discharge pipe 121 in a telescopic manner so as to close or open the powder discharge opening 1211. The telescopic connection of the sealing sleeve 122 and the powder discharge tube 121 means that the sealing sleeve 122 can slide along the axial direction of the sealing sleeve 122 relative to the powder discharge tube 121.

The sealing sleeve 122 may have a first position and a second position, and when the sealing sleeve 122 is in the first position, the side wall of the sealing sleeve 122 seals the powder discharge port 1211, referring to fig. 4, and at this time, the waste powder in the powder discharge tube 121 cannot be discharged from the powder discharge port 1211.

When the sealing sleeve 122 moves to the second position with respect to the powder discharge tube 121 toward the waste bin 111, the sealing sleeve 122 exposes the powder discharge port 1211, and referring to fig. 1, the waste powder in the powder discharge tube 121 may be discharged from the powder discharge port 1211.

When the waste powder in the waste powder bin 111 needs to be discharged into the waste powder cylinder, the sealing sleeve 122 is abutted against the flexible sealing piece 220, and then the waste powder cylinder is pressed towards the waste powder bin 111 along the axial direction of the powder discharge pipe 121, so that the waste powder cylinder pushes the sealing sleeve 122 to move to a second position to expose the powder discharge port 1211, and at the moment, the waste powder in the powder discharge pipe 121 enters the cylinder 210 through the powder discharge port 1211.

When the waste toner container or cartridge 110 is moved, the pressure applied to the waste toner container is released, and the sealing sleeve 122 is moved to the first position to block the toner discharge port 1211.

When it is necessary to discharge the waste powder in the waste powder bin 111 into the waste powder cylinder, the powder stirring screw 130 rotates to transfer the waste powder in the waste powder bin 111 to the powder discharge port 1211 and into the waste powder cylinder from the powder discharge port 1211.

Referring to fig. 4 and 5, in some embodiments, an end of seal sleeve 122 facing away from waste bin 111 may have a first notch 1225, where first notch 1225 corresponds to a location of guide ramp 1212 such that seal sleeve 122 exposes guide ramp 1212 through first notch 1225, such that when waste powder within waste bin 111 is discharged into a waste cartridge, only guide ramp 1212 abuts a corresponding flexible seal 220, and seal sleeve 122 corresponding to guide ramp 1212 does not abut flexible seal 220, further avoiding rupture of flexible seal 220.

Referring to fig. 1, 4 and 5, further, the first notch 1225 may have a first sidewall 1223 extending along a circumferential direction of the sealing sleeve 122, and the first sidewall 1223 may be parallel to a cross section of the sealing sleeve 122 or may be disposed obliquely with respect to the cross section of the sealing sleeve 122. The outside of the sealing sleeve 122 may be provided with a protrusion 1224, and when the powder discharge port assembly 120 is inserted into the waste powder cylinder, the waste powder cylinder may press the protrusion 1224, i.e., the flexible seal 220 may push against the protrusion 1224 to push the sealing sleeve 122 out of the powder discharge port 1211.

The end of the sealing sleeve 122 facing away from the waste bin 111 has a first end face 1226, and along the axial direction of the sealing sleeve 122, the minimum distance between the first side wall 1223 and the first end face 1226 may be equal to the minimum distance between the protruding portion 1224 and the first end face 1226, so that the flexible sealing member 220 abuts against the protruding portion 1224 and also abuts against the first side wall 1223, so as to better seal between the sealing sleeve 122 and the cylinder 210, thereby avoiding leakage of waste powder.
