The surface of the rubber ring 33 is in contact with the inner wall of the waste powder discharge hole 109.

[0030] During implementation, the user pulls the sealing cover 107 upwards, causing the sealing cover 107 to slide the connecting block 31 inside the fixing groove 32. The fixing groove 32 and the connecting block 31 work together to guide the sealing cover 107. At this time, the sealing cover 107 moves the silicone ring 34 and the rubber ring 33, causing the silicone ring 34 to move the rubber ring 33 away from the inner wall of the waste powder discharge hole 109. The user then discharges the waste powder from the waste powder bin through the discharge port 110 and the waste powder discharge hole 109. After the waste powder is discharged, the sealing cover 107 is then... The sealing cap 107 is placed on the surface of the waste powder discharge hole 109, so that the sealing cap 107 drives the connecting block 31 to slide inside the fixing groove 32. At this time, the sealing cap 107 drives the silicone ring 34 and the rubber ring 33 to move, so that the silicone ring 34 drives the rubber ring 33 to move to contact the inner wall of the waste powder discharge hole 109. Under the joint action of the silicone ring 34 and the rubber ring 33, the sealing cap 107 and the waste powder discharge hole 109 are sealed to prevent powder leakage, so as to realize the function of cleaning waste powder of the toner cartridge.

[0031] Furthermore, such as Figure 4 and Figure 7 As shown, the surfaces of the first side cover 101 and the second side cover 102 and the inner wall of the protective cover body 105 are provided with a protective anti-deformation mechanism 4. The protective anti-deformation mechanism 4 is composed of a positioning slot 41, an arc-shaped block 42, an arc-shaped slot 43 and an elastic clip 44. The surfaces of the first side cover 101 and the second side cover 102 are all equipped with elastic clips 44. The inner wall of the protective cover body 105 is provided with a positioning slot 41. The positioning slot 41 and the surface of the elastic clip 44 are engaged with each other. The surfaces of the first side cover 101 and the second side cover 102 are all equipped with arc-shaped blocks 42. The inner wall of the protective cover body 105 is provided with arc-shaped slots 43. The surfaces of the arc-shaped slots 43 and the arc-shaped blocks 42 are engaged with each other.

[0032] During implementation, the elastic clips 44 on the surfaces of the first side cover 101 and the second side cover 102 automatically engage with the inside of the positioning slot 41. Under the combined action of the positioning slot 41 and the elastic clips 44, the installation position of the protective cover body 105 is positioned. At this time, the arc-shaped clip 42 automatically engages with the inside of the arc-shaped slot 43.

This allows the protective cover body 105 to maintain a certain distance from the developing roller body 106 while also protecting the surface of the developing roller body 106, thereby realizing the function of the drum protecting the developing roller body 106 from deformation.

[0033] Working principle: In use, first place the toner cartridge housing 1 in the designated position. The user places the protective cover body 105 on the surface of the first side cover 101 and the second side cover 102 respectively. At this time, the user pushes the protective cover body 105. When the protective cover body 105 is pushed to the desired position, the elastic clips 44 on the surface of the first side cover 101 and the second side cover 102 automatically engage with the positioning slot 41. Under the combined action of the positioning slot 41 and the elastic clips 44, the installation position of the protective cover body 105 is positioned. At this time, the arc-shaped locking block... 42 automatically engages with the arc-shaped slot 43. The engagement of the arc-shaped slot 43 and the arc-shaped block 42 prevents the protective cover body 105 from detaching. This allows the protective cover body 105 to maintain a certain distance from the developing roller body 106 while also protecting the surface of the developing roller body 106. This achieves the function of protecting the developing roller body 106 from deformation by the toner cartridge, effectively solving the problem of the developing roller body 106 being deformed by pressure during use. This results in more stable performance, better printing quality, and a simple structure that is easy to manufacture.

[0034] Subsequently, after prolonged use, the surface of the developing roller body 106 inside the drum housing 1 tends to turn white, causing uneven or distorted printing during printing. When the user needs to clean the developing roller body 106 inside the drum housing 1, the user loosens the screws to remove the first side cover 101 and the second side cover 102 from the surface of the drum housing 1. The user then loosens the fastening studs 22 inside the fixing plate 23, moving the fastening studs 22 away from the surface of the gear assembly 108. The user then pulls the developing roller body 106 upwards to remove the developing roller body 106 and the gear assembly 108 from the drum housing.

Then, tighten the fastening stud 22 inside the screw hole 21. Under the action of the fastening stud 22, the developing roller body 106 and the gear assembly 108 are installed inside the drum housing 1. This enables the drum to be easily cleaned, allowing the user to easily remove the developing roller body 106 from the drum housing 1 and clean its surface. This makes the drum easier to operate.

[0035] Subsequently, the user pulls the sealing cover 107 upwards, causing the sealing cover 107 to slide the connecting block 31 inside the fixing groove 32. Under the combined action of the fixing groove 32 and the connecting block 31, the sealing cover 107 is guided. At this time, the sealing cover 107 drives the silicone ring 34 and the rubber ring 33 to move, causing the silicone ring 34 to drive the rubber ring 33 away from the inner wall of the waste powder discharge hole 109. The user discharges the waste powder inside the waste powder bin through the discharge port 110 and the waste powder discharge hole 109. After the waste powder is discharged, the sealing cover 107 is placed on the surface of the waste powder discharge hole 109, causing the sealing cover 107 to move... The connecting block 31 slides inside the fixing groove 32. At this time, the sealing cover 107 drives the silicone ring 34 and the rubber ring 33 to move, so that the silicone ring 34 drives the rubber ring 33 to contact the inner wall of the waste powder outlet hole 109. Under the joint action of the silicone ring 34 and the rubber ring 33, the sealing cover 107 and the waste powder outlet hole 109 are sealed to prevent powder leakage, so as to realize the function of cleaning waste powder of the toner cartridge. This allows the user to quickly discharge the waste powder inside the toner cartridge housing 1 when using the toner cartridge, making it more convenient to discharge waste powder from the toner cartridge and finally completing the use of the toner cartridge.
