Technical Field

[0001] This utility model relates to the field of toner cartridge technology, specifically to a toner cartridge with good sealing performance. Background Technology

[0002] Toner cartridges are a widely used detachable component in electronic imaging devices. When the toner in a cartridge is depleted, the old cartridge is replaced with a new one. The cartridge has a toner outlet and a switch. The switch is used to open and close the toner outlet to supply toner to the electronic imaging device. Existing toner cartridges have some shortcomings in use. To meet market needs, a toner cartridge with good sealing performance is required.

[0003] Existing toner cartridges have several drawbacks. The switch mechanism is prone to detachment, leading to toner leakage during transport and impacting usability. Furthermore, existing cartridges typically lack anti-caking features, preventing proper toner agitation and resulting in uneven toner distribution throughout the cartridge. This can cause inconsistent print quality and reduce print quality. Additionally, the sealing of existing cartridges needs improvement, reducing overall airtightness and making the toner susceptible to moisture absorption and leakage. Utility Model Content

[0004] The purpose of this invention is to provide a toner cartridge with good sealing performance, so as to solve the problems mentioned in the background art that toner cartridges usually do not have the function of preventing toner from condensing and that the sealing performance needs to be further improved.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a toner cartridge with good sealing performance, comprising a toner cartridge body, an outer shell provided on one side of the toner cartridge body, a first side cover provided on one side surface of both the toner cartridge body and the outer shell, the toner cartridge body and the outer shell being fastened to the surface threads of the first side cover by screws, a second side cover provided on one side of the toner cartridge body and the outer shell, a toner filling port provided on the surface of the toner filling port, a sealing cover provided on the surface of the toner filling port, a sponge roller provided inside the toner cartridge body, a second gear provided on the surface of the toner cartridge body, an assembly frame mounted on the surface of the toner cartridge body by screws, the second gear and the first gear extending into the interior of the assembly frame, an anti-condensation mechanism provided inside the toner cartridge body, and a high-sealing mechanism provided on the inner wall of the toner filling port and the surface of the sealing cover.

[0006] Preferably, the second side cover is threadedly fastened to the surface of the toner cartridge body and the first side cover by screws, one end of the sealing cover extends into the interior of the toner filling port, the surface of the outer shell is provided with a cover body, the sponge roller rotates with the inner wall of the toner cartridge body and the first side cover, one end of the sponge roller extends to the outer side of the second side cover, the surface of the toner cartridge body is provided with a first gear, the first gear rotates with the surface of the toner cartridge body, the first side cover is fastened to the assembly frame by screw threads, and the second gear rotates with the surface of the toner cartridge body.

[0007] Preferably, the anti-condensation mechanism consists of a rotating component, a stirring rod, a mounting head, and a gear body. The gear body is provided inside the toner cartridge body, and the gear body rotates and engages with the inner wall of the toner cartridge body. The surface of the gear body meshes with the surface of the second gear. The stirring rod for stirring the toner is provided inside the toner cartridge body.

[0008] Preferably, one end of the stirring rod is equipped with an installation head, which is fixed to the surface at the center of the gear body. The stirring rod rotates with the inner wall of the toner cartridge body. A rotating component is provided on the surface of the first side cover. The other end of the stirring rod passes through the assembly frame and is fixed to the surface at the center of the rotating component. The stirring rod rotates with the inner wall of the assembly frame.

[0009] Preferably, the high-sealing mechanism consists of a rubber ring, a silicone sealing gasket, a positioning block, and a positioning groove. The inner wall of the sealing cover is fitted with a rubber ring, and the surface of the rubber ring is wrapped with a silicone sealing gasket.

[0010] Preferably, the surface of the silicone sealing gasket is equipped with equally spaced positioning blocks, and the inner wall of the toner cartridge body is provided with positioning slots, and the positioning slots and the surfaces of the positioning blocks engage with each other.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the toner cartridge with good sealing performance not only allows the toner inside the cartridge to be turned over in all directions during use, keeping the toner in a loose state throughout the cartridge body, avoiding problems such as uneven density in different areas of the printed pattern, thus improving the printing effect of the laser printer, but also greatly improves the overall sealing performance of the toner cartridge during use, preventing the toner inside the cartridge body from getting damp, and at the same time, preventing toner leakage during use.

[0012] 1. By incorporating an anti-caking mechanism, the toner cartridge prevents caking when added, which can lead to uneven toner distribution and negatively impact print quality. The second gear rotates, causing the gear body to rotate inside the cartridge. This rotation, in turn, drives the stirring rod to rotate, agitating the toner throughout the cartridge and keeping it loose. This anti-caking mechanism ensures the toner cartridge maintains a consistent density and prevents uneven printing, improving the overall print quality of the laser printer.

[0013] 2. With a highly sealing mechanism, after the user adds toner to the cartridge body through the toner filling port, they place the sealing cap on the surface of the filling port. This causes one end of the sealing cap to move into the filling port, moving the rubber ring and silicone sealing gasket. The rubber ring then moves the silicone sealing gasket until it contacts the inner wall of the filling port, sealing the area between the sealing cap and the filling port. At this point, the silicone sealing gasket moves the positioning block into the corresponding positioning slot, preventing the sealing cap from detaching. Therefore, unless the user pulls the sealing cap outwards, it will not loosen from the filling port, achieving a highly sealed function for the toner cartridge. This significantly improves the overall sealing performance of the toner cartridge, preventing moisture absorption of the toner inside and avoiding toner leakage during use.

[0024] The present invention provides a toner cartridge with good sealing performance, as shown in the following structure. Figures 1 to 4As shown, the device includes a toner cartridge body 1, a housing 101 on one side of the toner cartridge body 1, and a first side cover 102 on one side of both the toner cartridge body 1 and the housing 101. The toner cartridge body 1 and the housing 101 are respectively threaded onto the surface of the first side cover 102 by screws. A second side cover 103 is provided on one side of the toner cartridge body 1 and the housing 101, and the second side cover 103 is threaded onto the surface of both the toner cartridge body 1 and the first side cover 102 by screws. One end of a sealing cap 110 extends into the interior of the toner filling port 104. A cover body 105 is provided on the surface of the housing 101. A sponge roller 106 rotates and engages with the inner walls of the toner cartridge body 1 and the first side cover 102. One end of the sponge roller 106 extends into the interior of the toner filling port 104. On the outer side of the second side cover 103, the surface of the toner cartridge body 1 is provided with a first gear 107. The first gear 107 rotates and engages with the surface of the toner cartridge body 1. The first side cover 102 and the assembly frame 109 are fastened together by screw threads. The surface of the toner cartridge body 1 is provided with a second gear 108. The second gear 108 rotates and engages with the surface of the toner cartridge body 1. The surface of the toner cartridge body 1 is provided with a toner filling port 104. The surface of the toner filling port 104 is provided with a sealing cover 110. The interior of the toner cartridge body 1 is provided with a sponge roller 106. The surface of the toner cartridge body 1 is mounted with an assembly frame 109 by screws. The second gear 108 and the first gear 107 extend into the interior of the assembly frame 109.

[0025] Furthermore, such as Figure 5 and Figure 6 As shown, the toner cartridge body 1 is equipped with an anti-condensation mechanism 2 inside. The anti-condensation mechanism 2 consists of a rotating component 21, a stirring rod 22, a mounting head 23, and a gear body 24. The gear body 24 is installed inside the toner cartridge body 1 and rotates with the inner wall of the toner cartridge body 1. The surface of the gear body 24 meshes with the surface of the second gear 108. The stirring rod 22 for stirring the toner is installed inside the toner cartridge body 1. One end of the stirring rod 22 is equipped with a mounting head 23, which is fixed to the surface at the center of the gear body 24. The stirring rod 22 rotates with the inner wall of the toner cartridge body 1. The surface of the first side cover 102 is equipped with a rotating component 21. The other end of the stirring rod 22 passes through the assembly frame 109 and is fixed to the surface at the center of the rotating component 21. The stirring rod 22 rotates with the inner wall of the assembly frame 109.

[0026] During implementation, when toner is added to the interior of the toner cartridge body 1, it is easy for the toner to clump together, resulting in uneven toner distribution and severely affecting the printing effect. When the second gear 108 rotates, it drives the gear body 24 to rotate inside the toner cartridge body 1. When the gear body 24 rotates, the mounting head 23 drives the stirring rod 22 to rotate inside the toner cartridge body 1. Under the action of the stirring rod 22, the toner inside the toner cartridge body 1 is turned over in all directions, keeping the toner in a loose state throughout the toner cartridge body 1, so as to achieve the function of preventing toner clumping.

[0027] Furthermore, such as Figure 7 and Figure 8 As shown, a high-sealing mechanism 3 is provided on the inner wall of the toner filling port 104 and the surface of the sealing cover 110. The high-sealing mechanism 3 consists of a rubber ring 31, a silicone sealing gasket 32, a positioning block 33, and a positioning groove 34. The inner wall of the sealing cover 110 is fitted with a rubber ring 31, and the surface of the rubber ring 31 is wrapped with a silicone sealing gasket 32. The surface of the silicone sealing gasket 32 ​​is in contact with the inner wall of the toner filling port 104. The surface of the silicone sealing gasket 32 ​​is equipped with equally spaced positioning blocks 33. The inner wall of the toner cartridge body 1 is provided with positioning grooves 34, and the surfaces of the positioning grooves 34 and the positioning blocks 33 are engaged with each other.

[0028] In practice, after adding toner into the toner cartridge body 1 through the toner filling port 104, the user places the sealing cap 110 on the surface of the toner filling port 104, causing one end of the sealing cap 110 to move into the toner filling port 104. The sealing cap 110 drives the rubber ring 31 and the silicone sealing gasket 32 ​​to move, and the rubber ring 31 drives the silicone sealing gasket 32 ​​to contact the inner wall of the toner filling port 104. Under the action of the silicone sealing gasket 32, the sealing cap 110 and the toner filling port 104 are sealed. At this time, the silicone sealing gasket 32 ​​drives the positioning block 33 to lock into the corresponding positioning slot 34. Under the locking action of the positioning block 33 and the positioning slot 34, the sealing cap 110 is prevented from falling off. Therefore, if the user does not pull the sealing cap 110 outward, the sealing cap 110 will not fall off from the inside of the toner filling port 104, thus achieving the high sealing function of the toner cartridge.

[0029] Working principle: In use, first place the toner cartridge body 1 in the designated position. The user then uses screws to install the assembly bracket 109 onto the surface of the toner cartridge body 1. Next, screws are used to install the first side cover 102 and the second side cover 103 onto the surfaces of the toner cartridge body 1 and the outer casing 101, respectively. Then, the user opens the cover 105 and removes it from the surface of the outer casing 101 to empty the waste toner inside. The sealing cover 110 is then removed from the surface of the toner cartridge body 1 by pulling upwards. During use... Toner is added to the interior of the toner cartridge body 1 through the toner filling port 104. When the second gear 108 rotates, it drives the sponge roller 106 to rotate inside the toner cartridge body 1 for printing. According to existing technology, the interior of the toner cartridge also includes a toner delivery mechanism and a cleaning system. The toner delivery mechanism is responsible for evenly delivering toner to the OPC drum, and the cleaning system is responsible for removing toner residue on the OPC drum. Under the action of the sponge roller 106, toner is provided to the surface of the developing roller in the drum, and toner that has not been adsorbed onto the OPC drum is cleaned.

[0030] Subsequently, when toner is added to the interior of the toner cartridge body 1, it is easy for the toner to clump together, resulting in uneven toner distribution and severely affecting the printing effect. When the second gear 108 rotates, it drives the gear body 24 to rotate inside the toner cartridge body 1. When the gear body 24 rotates, the mounting head 23 drives the stirring rod 22 to rotate inside the toner cartridge body 1. Under the action of the stirring rod 22, the toner inside the toner cartridge body 1 is turned over in all directions, keeping the toner in a loose state throughout the toner cartridge body 1. This achieves the function of preventing toner clumping, allowing the toner cartridge to turn over in all directions during use, keeping the toner in a loose state throughout the toner cartridge body 1, avoiding problems such as uneven density in the printed pattern, and improving the printing effect of the laser printer.

[0031] Subsequently, the user adds toner into the toner cartridge body 1 through the toner filling port 104, and then places the sealing cap 110 on the surface of the toner filling port 104, causing one end of the sealing cap 110 to move into the interior of the toner filling port 104. The sealing cap 110 drives the rubber ring 31 and the silicone sealing gasket 32 ​​to move, and the rubber ring 31 drives the silicone sealing gasket 32 ​​to contact the inner wall of the toner filling port 104. Under the action of the silicone sealing gasket 32, a seal is formed between the sealing cap 110 and the toner filling port 104. At this time, the silicone sealing gasket 32 ​​drives the positioning block 33 to lock in place. Inside the corresponding positioning slot 34, the sealing cover 110 is prevented from detaching under the interlocking action of the positioning block 33 and the positioning slot 34. Therefore, if the user does not pull the sealing cover 110 outward, the sealing cover 110 will not loosen from the inside of the toner filling port 104, thus achieving the high sealing performance of the toner cartridge. This greatly improves the overall sealing performance of the toner cartridge during use, preventing the toner inside the toner cartridge body 1 from getting damp. At the same time, it can prevent toner leakage during the use of the toner cartridge, thus completing the use of the toner cartridge.

[0032] 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.
