Description

Technical Field

[0001] This utility model relates to the field of toner cartridge technology, specifically to a toner cartridge that is easy to clean waste toner. Background Technology

[0002] Toner cartridges are a common printing consumable. Inside a toner cartridge are structural components such as a toner hopper, magnetic roller, and photosensitive drum. The photosensitive drum is used to transfer toner onto paper. To prevent impurities on the photosensitive drum from affecting its toner adsorption, a scraper is often installed on the photosensitive drum. The scraper removes waste toner from the surface of the photosensitive drum, and then the waste toner falls into the waste toner hopper. Existing toner cartridges have some shortcomings in cleaning waste toner. To meet market needs, there is a need for a toner cartridge that is easy to clean waste toner.

[0003] Existing toner cartridges suffer from several drawbacks. Waste toner adheres to the walls of the waste toner compartment, hindering cleaning. The inconvenient cleaning process prevents the removal of residual waste toner from the inner wall of the cartridge, leading to residue buildup. Furthermore, existing cartridges lack precise chip positioning, compromising chip stability within the mounting slot and hindering chip replacement. Finally, their leak-proof design is inadequate, allowing toner to leak between the filling port and the sealing cap, compromising overall sealing. Utility Model Content

[0004] The purpose of this invention is to provide a toner cartridge that is easy to clean, in order to solve the problems mentioned in the background art, such as the inconvenience of cleaning waste toner when using the toner cartridge, the inability to position and install the chip body, and the insufficient anti-leakage effect.

[0006] Preferably, the photosensitive drum and the inner wall of the toner cartridge body are rotatably engaged. A drive gear is mounted on the surface of the photosensitive drum, and the drive gear is rotatably engaged with the inner wall of the toner cartridge body. A waste toner inlet is provided on the surface of the toner cartridge body, and a waste toner cover is provided on the surface of the waste toner inlet. One end of the waste toner cover passes through the waste toner inlet and extends into the interior of the toner cartridge body. A magnetic roller is provided inside the toner cartridge body, and the magnetic roller is rotatably engaged with the inner wall of the toner cartridge body.

[0007] Preferably, the easy-cleaning mechanism consists of a toner adsorption roller, a tapping strip, a second gear, a rotating column, a first gear, and a mounting block. The interior of the drum body is provided with a toner adsorption roller for cleaning waste toner. The surface of the toner adsorption roller and the rotating frame rotate in mutual engagement. The inner wall of the drum body is provided with a rotating column, which rotates in mutual engagement with the inner wall of the drum body. The surface of the rotating column is equipped with a mounting block, which engages with the surface of the toner adsorption roller.

[0008] Preferably, the surface of the toner adsorption roller is equipped with equally spaced tapping strips, the surface of the toner adsorption roller is fitted with a second gear, the inside of the drum body is provided with a first gear, the first gear and the second gear mesh with each other, the first gear rotates with the inner wall of the drum body, and the first gear meshes with the drive gear.

[0009] Preferably, the positioning and installation mechanism consists of a support plate, a first positioning post, a second positioning post, and a limiting block. The surface of each fixing groove is equipped with a first positioning post, the surface of which is in contact with the surface of the chip body. The inner wall of each fixing groove is equipped with a limiting block for limiting the installation of the chip body, the surface of which is in contact with the surface of the chip body.

[0010] Preferably, a second positioning post is installed on the inner wall of the fixing groove, the surface of the second positioning post is in contact with the surface of the chip body, and a support plate for supporting the chip body is installed on the inner wall of the fixing groove, the surface of the support plate is in contact with the surface at the bottom of the chip body.

[0011] Preferably, the anti-leakage mechanism consists of a rubber ring, a silicone pad, an elastic block, and a fixing groove. The surface of the sealing cover is wrapped with a rubber ring, and the surface of the rubber ring is wrapped with a silicone pad for sealing the gap between the sealing cover and the powder filling port to prevent powder leakage. The surface of the silicone pad is in contact with the inner wall of the powder filling port.

[0012] Preferably, the surface of the silicone pad is equipped with elastic clips, and the inner wall of the powder filling port is provided with a fixing groove, which engages with the surface of the elastic clip.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the toner cartridge that is easy to clean not only allows the waste toner remaining on the inner wall of the toner cartridge to be knocked off during use, so that the waste toner does not adhere to the inner wall and does not cause waste toner residue, but also ensures the stability of the chip body when it is installed in the fixing slot. At the same time, it makes it convenient for users to disassemble and replace the chip body. Moreover, it prevents toner from leaking out from between the toner filling port and the sealing cap during use, resulting in a higher overall sealing performance of the toner cartridge.

[0014] 1. By incorporating a cleaning mechanism, the meshing of the first and second gears drives the second gear to rotate inside the drum body. This second gear, in turn, drives a rotating column to rotate inside the drum body. As the column rotates, it drives the toner adsorption roller and the tapping bar to rotate inside the waste toner compartment of the drum body. The toner adsorption roller rotates with the drive gear, allowing for more even adsorption of waste toner. The toner adsorption roller adsorbs the waste toner that falls into the drum body's waste toner compartment, and the tapping bar then knocks off the waste toner remaining on the inner wall of the drum body. This facilitates waste toner cleaning, preventing waste toner residue from adhering to the inner wall during use.

[0015] 2. With the positioning and installation mechanism, the user places the chip body on the surface of the fixing slot. The first and second positioning posts work together to position the chip body. The limiting block limits the chip body's position, making it less likely to come loose during use. When the chip body is installed on the surface of the fixing slot, the support plate supports the bottom of the chip body, making it more stable during use. This realizes the function of positioning and installing the chip body in the toner cartridge, ensuring the stability of the chip body when it is installed in the fixing slot. At the same time, it makes it convenient for the user to disassemble and replace the chip body.

[0016] 3. With the addition of a leak-proof mechanism, the user places the sealing cap on the surface of the toner filling port. This causes the sealing cap to move the rubber ring and silicone pad. After the rubber ring and silicone pad move into the inside of the toner filling port, the silicone pad moves to contact the inner wall of the toner filling port. At this time, the elastic clip on the surface of the silicone pad automatically engages with the corresponding fixing groove. The engagement of the elastic clip and the fixing groove prevents the sealing cap from coming loose from the surface of the toner filling port. The combined action of the rubber ring and silicone pad seals the gap between the sealing cap and the toner filling port, achieving the leak-proof function of the toner cartridge. This prevents toner from leaking out between the toner filling port and the sealing cap during use, resulting in a higher overall sealing performance of the toner cartridge.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0024] This utility model provides a structure for a toner cartridge that facilitates the cleaning of waste powder, as shown in the following figure. Figure 1 and Figure 2As shown, the device includes a toner cartridge body 1. A second side cover 102 is provided on one side of the toner cartridge body 1, and the second side cover 102 is fixed to the surface of the toner cartridge body 1 by screws. A first side cover 101 is provided on the side of the toner cartridge body 1 away from the second side cover 102, and the first side cover 101 is fixed to the surface of the toner cartridge body 1 by screws. A photosensitive drum 103 is provided on the surface of the toner cartridge body 1, and the photosensitive drum 103 rotates with the inner wall of the toner cartridge body 1. A drive gear 104 is mounted on the surface of the photosensitive drum 103, and the drive gear 104 rotates with the inner wall of the toner cartridge body 1. A waste toner outlet is provided on the surface of the toner cartridge body 1, and a waste toner cover 10 is provided on the surface of the waste toner outlet. 6. One end of the waste toner cover 106 passes through the waste toner inlet and extends into the interior of the drum body 1. A magnetic roller 107 is provided inside the drum body 1. The magnetic roller 107 rotates and engages with the inner wall of the drum body 1. A fixing groove 108 is provided on the surface of the first side cover 101. A chip body 109 is placed inside the fixing groove 108. A toner filling port 110 is installed on the surface of the first side cover 101. The toner filling port 110 is connected to the interior of the drum body 1. A sealing cover 111 is provided on the surface of the toner filling port 110. One end of the sealing cover 111 extends into the interior of the toner filling port 110. A rotating frame 105 is provided on the drum body 1. The rotating frame 105 engages and engages with the inner wall of the drum body 1.

[0025] Furthermore, such as Figure 2 and Figure 4 As shown, the drum body 1 has a cleaning mechanism 2 inside, which consists of a toner adsorption roller 21, a tapping strip 22, a second gear 23, a rotating column 24, a first gear 25, and a mounting block 26. The drum body 1 has a toner adsorption roller 21 for cleaning waste toner. The toner adsorption roller 21 rotates with the surface of the rotating frame 105. The inner wall of the drum body 1 has a rotating column 24, which rotates with the inner wall of the drum body 1. The surface of the rotating column 24 is fitted with a mounting block 26, which engages with the surface of the toner adsorption roller 21. The surface of the toner adsorption roller 21 is fitted with equally spaced tapping strips 22. The surface of the toner adsorption roller 21 is fitted with a second gear 23. The drum body 1 has a first gear 25 inside, which meshes with the second gear 23. The first gear 25 rotates with the inner wall of the drum body 1 and meshes with the drive gear 104.

[0026] In practice, when the drive gear 104 rotates, it drives the first gear 25 to rotate inside the drum body 1. The meshing of the first gear 25 and the second gear 23 drives the second gear 23 to rotate inside the drum body 1. At this time, the second gear 23 drives the rotating column 24 to rotate inside the drum body 1. When the rotating column 24 rotates, it drives the toner adsorption roller 21 and the tapping bar 22 to rotate inside the waste toner compartment of the drum body 1. The toner adsorption roller 21 rotates with the drive gear 104, thus making the adsorption of waste toner more even. Under the action of the toner adsorption roller 21, the waste toner is adsorbed more evenly. Waste toner that falls into the waste toner compartment of the drum body 1 is adsorbed and then the waste toner remaining on the inner wall of the drum body 1 is knocked off by the tapping bar 22, so that the waste toner does not adhere to the inner wall of the drum body 1. After the user loosens the screw and removes the second side cover 102 from the surface of the drum body 1, he pulls the toner adsorption roller 21 so that the toner adsorption roller 21 is away from the surface of the mounting block 26. At this time, the toner adsorption roller 21 drives the rotating frame 105 away from the inner wall of the drum body 1, so that the toner adsorption roller 21 and the tapping bar 22 can be removed from the inside of the drum body 1, thereby facilitating the cleaning of the toner inside the waste toner compartment of the drum body 1, so as to realize the function of cleaning waste toner from the drum.

[0027] Furthermore, such as Figure 3 and Figure 5 As shown, a powder leakage prevention mechanism 4 is provided on the surface of the sealing cap 111 and the inner wall of the powder filling port 110. The powder leakage prevention mechanism 4 consists of a rubber ring 41, a silicone pad 42, an elastic block 43, and a fixing groove 44. The surface of the sealing cap 111 is covered with a rubber ring 41, and the surface of the rubber ring 41 is covered with a silicone pad 42 for sealing the powder filling port 110 and preventing powder leakage. The surface of the silicone pad 42 is in contact with the inner wall of the powder filling port 110. An elastic block 43 is installed on the surface of the silicone pad 42. A fixing groove 44 is opened on the inner wall of the powder filling port 110. The fixing groove 44 and the surface of the elastic block 43 are engaged with each other.

[0028] During implementation, after refilling the toner, the user places the sealing cap 111 on the surface of the toner filling port 110, causing the sealing cap 111 to move the rubber ring 41 and the silicone pad 42. After the rubber ring 41 and the silicone pad 42 move into the interior of the toner filling port 110, the silicone pad 42 moves to contact the inner wall of the toner filling port 110. At this time, the elastic locking block 43 on the surface of the silicone pad 42 automatically locks into the corresponding fixing slot 44. Under the locking action of the elastic locking block 43 and the fixing slot 44, the sealing cap 111 can be prevented from loosening from the surface of the toner filling port 110. Under the joint action of the rubber ring 41 and the silicone pad 42, the sealing cap 111 and the toner filling port 110 are sealed to achieve the function of preventing toner leakage from the drum.

[0029] Furthermore, such as Figure 3 As shown, a positioning and mounting mechanism 3 is provided inside the fixing groove 108. The positioning and mounting mechanism 3 consists of a support plate 31, a first positioning post 32, a second positioning post 33, and a limiting block 34. The first positioning post 32 is installed on the surface of the fixing groove 108, and the surface of the first positioning post 32 is in contact with the surface of the chip body 109. The inner wall of the fixing groove 108 is installed with a limiting block 34 for limiting the installation of the chip body 109, and the surface of the limiting block 34 is in contact with the surface of the chip body 109. The inner wall of the fixing groove 108 is installed with a second positioning post 33, and the surface of the second positioning post 33 is in contact with the surface of the chip body 109. The inner wall of the fixing groove 108 is installed with a support plate 31 for supporting the chip body 109, and the surface of the support plate 31 is in contact with the surface at the bottom of the chip body 109.

[0030] During implementation, the user places the chip body 109 on the surface of the fixing slot 108. The first positioning post 32 and the second positioning post 33 work together to position the chip body 109. The limiting block 34 limits the installation position of the chip body 109, making it less likely for the chip body 109 to come loose during use. When the chip body 109 is installed on the surface of the fixing slot 108, the bottom of the chip body 109 is supported by the support plate 31, making the chip body 109 more stable during use, thus realizing the function of positioning and installing the chip body 109 in the toner cartridge.

[0031] Working Principle: In use, first place the drum unit 1 in the designated position. When the drum unit 1 is working, the drive gear 104 drives the photosensitive drum 103 to rotate inside the drum unit 1. As the drive gear 104 rotates, it drives the first gear 25 to rotate inside the drum unit 1. The meshing of the first gear 25 and the second gear 23 drives the second gear 23 to rotate inside the drum unit 1. At this time, the second gear 23 drives the rotating column 24 to rotate inside the drum unit 1. When the rotating column 24 rotates, it drives the toner adsorption roller 21 and the tapping bar 22 to rotate inside the waste toner compartment of the drum unit 1. The toner adsorption roller 21 rotates with the drive gear 104, thus making the adsorption of waste toner more even. Under the action of the toner adsorption roller 21... The waste toner that falls into the waste toner compartment of the drum body 1 is adsorbed and then the waste toner remaining on the inner wall of the drum body 1 is knocked off by the tapping bar 22, so that the waste toner does not adhere to the inner wall of the drum body 1. After the user loosens the screw and removes the second side cover 102 from the surface of the drum body 1, he pulls the toner adsorption roller 21 so that the toner adsorption roller 21 is away from the surface of the mounting block 26. At this time, the toner adsorption roller 21 drives the rotating frame 105 away from the inner wall of the drum body 1, so that the toner adsorption roller 21 and the tapping bar 22 can be removed from the inside of the drum body 1, thereby facilitating the cleaning of the toner inside the waste toner compartment of the drum body 1, so as to realize the function of easy cleaning of waste toner. This allows the waste toner remaining on the inner wall of the drum body 1 to be knocked off when the drum is used, so that the waste toner does not adhere to the inner wall and does not cause waste toner residue. After the user removes the waste powder cover 106 from the surface of the waste powder inlet, the waste powder is poured out from the inside of the waste powder bin through the waste powder inlet.

[0032] Subsequently, the user places the chip body 109 on the surface of the fixing slot 108. Under the combined action of the first positioning post 32 and the second positioning post 33, the installation position of the chip body 109 can be positioned. Under the action of the limiting block 34, the installation position of the chip body 109 is limited, making it less likely for the chip body 109 to loosen during use. When the chip body 109 is installed on the surface of the fixing slot 108, the bottom of the chip body 109 is supported by the support plate 31, making the chip body 109 more stable during use. This realizes the function of positioning and installing the chip body 109 in the toner cartridge, thereby ensuring the stability of the chip body 109 when it is installed inside the fixing slot 108 during toner cartridge use. At the same time, it is convenient for the user to disassemble and replace the chip body 109.

[0033] Subsequently, the user pulls the sealing cover 111 to remove it from the surface of the toner filling port 110, and adds toner into the drum body 1 through the toner filling port 110. After adding toner, the user places the sealing cover 111 back onto the surface of the toner filling port 110, causing the sealing cover 111 to move the rubber ring 41 and the silicone pad 42. After the rubber ring 41 and the silicone pad 42 move into the interior of the toner filling port 110, the silicone pad 42 moves to contact the inner wall of the toner filling port 110. At this time, the elastic locking block 43 on the surface of the silicone pad 42 automatically locks in place. Inside the corresponding fixing slot 44, the locking action of the elastic block 43 and the fixing slot 44 can prevent the sealing cover 111 from loosening from the surface of the toner filling port 110. Under the combined action of the rubber ring 41 and the silicone pad 42, the sealing cover 111 and the toner filling port 110 are sealed to achieve the function of preventing toner leakage from the toner cartridge. This prevents toner from leaking out from between the toner filling port 110 and the sealing cover 111 when the toner cartridge is in use, resulting in a higher overall sealing performance of the toner cartridge and ultimately completing the use of the toner cartridge.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. 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. No reference numerals in the claims should be construed as limiting the scope of the claims.
