[0009] Preferably, the external powder feeding mechanism consists of a sealing plug, a silicone ring, a positioning clip, and a rubber ring. The surface of the second side cover is provided with a sealing plug for sealing the surface of the powder feeding port. One end of the sealing plug passes through the second side cover and extends into the interior of the powder feeding port. The surface of the sealing plug is wrapped with a rubber ring.

[0010] Preferably, a silicone ring is adhered to the surface of the rubber ring to seal the gap between the sealing plug and the powder filling port to prevent powder leakage. The inner wall of the silicone ring is in contact with the inner wall of the powder filling port. Positioning clips are installed on the surface of the silicone ring, and the positioning clips are engaged with the inner wall of the powder filling port.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the large-capacity toner cartridge structure not only allows the toner cartridge to hold more toner during use, improving work efficiency, but also ensures the printer's print quality and reduces downtime caused by replacing the toner cartridge body.

[0013] 2. By incorporating an external toner filling mechanism, the user pulls the sealing plug on the surface of the toner filling port outwards, causing it to move away from the port. This movement drives the rubber and silicone rings, moving the silicone ring away from the inner wall of the filling port. The sealing plug is then removed from the surface of the filling port, allowing toner to be added to the toner cartridge body through the filling port. After filling, the sealing plug moves the rubber and silicone rings to the inside of the filling port, where the silicone ring adheres to the inner wall. The silicone ring then automatically engages with the positioning clip, sealing the surface of the filling port under the combined action of the silicone and rubber rings. This prevents toner leakage from the cartridge body through the filling port and the sealing plug, achieving an external toner filling function. This eliminates the need to remove the second side cover from the cartridge body for toner filling, making the toner cartridge more convenient to use and ensuring the toner's internal seal.

[0022] The present invention provides a large-capacity toner cartridge structure as follows: Figure 1 and Figure 2As shown, the device includes a toner cartridge body 1. A connecting frame 105 is mounted on the surface of the toner cartridge body 1. A first side cover 101 is provided on the surface of the connecting frame 105. One end of the connecting frame 105 extends into the interior of the first side cover 101. Positioning members 102 are mounted on the surface of the first side cover 101. The positioning members 102 are engaged with the inner wall of the connecting frame 105. A gear set 104 is provided on the surface of the connecting frame 105. The gear set 104 rotates with the surface of the connecting frame 105. The surface of the connecting frame 105 is provided with... There is a rotating gear 107, which rotates and engages with the surface of the connecting frame 105. One end of the rotating gear 107 passes through the connecting frame 105 and the toner cartridge body 1 and extends into the interior of the toner cartridge body 1. A drive gear 108 is provided on the surface of the connecting frame 105, which rotates and engages with the surface of the connecting frame 105. A second side cover 103 is installed on one side of the toner cartridge body 1 by screws. Both the surface of the toner cartridge body 1 and the second side cover 103 are provided with a toner filling port 106.

[0023] Furthermore, such as Figure 3 and Figure 5 As shown, the interior of the toner cartridge body 1 and the surface of the connecting frame 105 are provided with a toner quantity increasing mechanism 2. The toner quantity increasing mechanism 2 is composed of a first mounting cylinder 21, a second mounting cylinder 22, a first gear body 23, a first stirring frame 24, a second stirring frame 25, and a second gear body 26. The second mounting cylinder 22 is mounted on the surface of the connecting frame 105, and the first mounting cylinder 21 is mounted on the surface of the connecting frame 105. The first gear body 23 is sleeved on the surface of the second mounting cylinder 22. The first gear body 23 and the surface of the first mounting cylinder 21 are rotatably engaged with each other. The first gear body 23 and the inner wall of the first side cover 101 are rotatably engaged with each other. The first gear body 23 meshes with the rotating gear 107 and the driving gear 108 respectively. The first mounting cylinder 21... A second gear body 26 is fitted onto the surface of the first mounting cylinder 21. The second gear body 26 rotates and engages with the surface of the first mounting cylinder 21. The second gear body 26 rotates and engages with the inner wall of the first side cover 101. The second gear body 26 meshes with the surface of the drive gear 108. The second gear body 26 meshes with the gear set 104. A first stirring frame 24 for stirring toner is mounted on the surface of the first gear body 23. One end of the first stirring frame 24 extends into the interior of the toner cartridge body 1 and rotates and engages with the inner wall of the toner cartridge body 1. A second stirring frame 25 is mounted on the surface of the second gear body 26. One end of the second stirring frame 25 extends into the interior of the toner cartridge body 1 and rotates and engages with the inner wall of the toner cartridge body 1.

[0024] In practice, when the drive gear 108 rotates, the meshing action of the drive gear 108 with the second gear body 26 and the first gear body 23 drives the second gear body 26 and the first gear body 23 to rotate on the surfaces of the first mounting cylinder 21 and the second mounting cylinder 22, respectively. At this time, the second gear body 26 drives the gear set 104 to rotate on the surface of the connecting frame 105. When the first gear body 23 and the second gear body 26 rotate, the first gear body 23 and the second gear body 26 drive the first stirring frame 24 and the second stirring frame 25 to rotate inside the toner cartridge body 1, and stir the toner inside the toner cartridge body 1. The design of the first gear body 23 with the first stirring frame 24 and the second stirring frame 25 with the second gear body 26 makes the toner inside the toner cartridge body 1 more uniform when it is dispensed, which helps to improve the printing quality and realize the function of increasing the toner volume of the toner cartridge structure.

[0025] Furthermore, such as Figure 4 and Figure 6 As shown, an external powder feeding mechanism 3 is provided on the surface of the powder feeding port 106. The external powder feeding mechanism 3 is composed of a sealing plug 31, a silicone ring 32, a positioning clip 33, and a rubber ring 34. A sealing plug 31 for sealing the surface of the powder feeding port 106 is provided on the surface of the second side cover 103. One end of the sealing plug 31 passes through the second side cover 103 and extends into the interior of the powder feeding port 106. The surface of the sealing plug 31 is wrapped with a rubber ring 34. A silicone ring 32 for sealing and preventing powder leakage between the sealing plug 31 and the powder feeding port 106 is adhered to the surface of the rubber ring 34. The inner wall of the silicone ring 32 is in contact with the inner wall of the powder feeding port 106. Positioning clips 33 are installed on the surface of the silicone ring 32. The positioning clips 33 are engaged with the inner wall of the powder feeding port 106.

[0026] During implementation, the user pulls the sealing plug 31 on the surface of the toner filling port 106 outwards, causing the sealing plug 31 to move away from the toner filling port 106. The sealing plug 31 drives the rubber ring 34 and silicone ring 32 to move, causing the silicone ring 32 to move away from the inner wall of the toner filling port 106, thus removing the sealing plug 31 from the surface of the toner filling port 106. Toner is then added into the toner cartridge body 1 through the toner filling port 106. After adding toner, the user places the sealing plug 31 on the surface of the toner filling port 106 and then pushes the sealing plug 31 back into the toner filling port 106. 1. This causes the sealing plug 31 to move the rubber ring 34 and silicone ring 32 to the inside of the toner filling port 106. The silicone ring 32 is in contact with the inner wall of the toner filling port 106. The silicone ring 32 drives the positioning clip 33 to automatically lock onto the inner wall of the toner filling port 106. Under the combined action of the silicone ring 32 and the rubber ring 34, the surface of the toner filling port 106 is sealed, preventing the toner inside the toner cartridge body 1 from leaking out between the toner filling port 106 and the sealing plug 31, so as to realize the function of external toner filling of the toner cartridge structure.

[0027] Working principle: In use, first place the toner cartridge body 1 in the designated position. The user assembles the first side cover 101 and the second side cover 103 onto the surfaces of the two sides of the toner cartridge body 1, respectively. The external drive device (not shown in the diagram) drives the drive gear 108 to rotate on the surface of the connecting frame 105. When the drive gear 108 rotates, under the meshing action of the drive gear 108 with the second gear body 26 and the first gear body 23, the second gear body 26 and the first gear body 23 are driven to rotate on the surfaces of the first mounting cylinder 21 and the second mounting cylinder 22, respectively. At this time, the second gear body 26 drives the gear set 104 to rotate on the surface of the connecting frame 105. When the first gear body 23 and the second gear... When the main body 26 rotates, the first gear body 23 and the second gear body 26 respectively drive the first stirring frame 24 and the second stirring frame 25 to rotate inside the toner cartridge body 1, stirring the toner inside the toner cartridge body 1. The design of the first gear body 23 and the first stirring frame 24 and the second stirring frame 25 and the second gear body 26 makes the toner inside the toner cartridge body 1 more uniform when dispensing, which helps to improve print quality. This realizes the function of increasing the toner volume of the toner cartridge structure, so that the toner cartridge structure can hold more toner when in use, improving work efficiency while ensuring the print quality of the printer and reducing downtime caused by replacing the toner cartridge body 1.

[0028] Subsequently, when the first gear body 23 rotates on the surface of the connecting frame 105, the meshing action of the first gear body 23 and the rotating gear 107 drives the rotating gear 107 to rotate on the surface of the connecting frame 105, thereby driving the toner scraper plate (not shown in the diagram) to rotate inside the toner cartridge body 1, promoting the flow of toner inside the toner cartridge body 1, and providing uniform toner supply to the printer. If the user needs to add toner to the inside of the toner cartridge body 1, the user pulls the sealing plug 31 on the surface of the toner filling port 106 outward, causing the sealing plug 31 to move away from the toner filling port 106. The sealing plug 31 drives the rubber ring 34 and the silicone ring 32 to move, causing the silicone ring 32 to move away from the inner wall of the toner filling port 106. The sealing plug 31 is then removed from the surface of the toner filling port 106, and toner is added to the inside of the toner cartridge body 1 through the toner filling port 106. After adding toner, the user places the sealing plug 31 back on the surface of the toner filling port 106. Push the sealing plug 31 onto the surface of the toner filling port 106, causing the sealing plug 31 to move the rubber ring 34 and silicone ring 32 to the inside of the toner filling port 106. The silicone ring 32 is in contact with the inner wall of the toner filling port 106, and the silicone ring 32 drives the positioning clip 33 to automatically lock onto the inner wall of the toner filling port 106. Under the combined action of the silicone ring 32 and the rubber ring 34, the surface of the toner filling port 106 is sealed, preventing the toner inside the toner cartridge body 1 from leaking out between the toner filling port 106 and the sealing plug 31. This realizes the function of external toner filling of the toner cartridge structure, so that the second side cover 103 does not need to be removed from the surface of the toner cartridge body 1 to add toner when using the toner cartridge structure. This makes the toner cartridge structure more convenient to operate when using, and at the same time, it can ensure the sealing of the toner inside the toner cartridge body 1, thus completing the use of the toner cartridge structure.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
