Description

Technical Field

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

[0002] Toner cartridges are a key consumable in laser printers, copiers, and multifunction printers. A toner cartridge typically consists of a plastic casing, a toner container, a charging roller, a magnetic roller, and other electronic components. During the printing process, the toner is evenly charged and adsorbed onto the photosensitive drum, then transferred to the paper through a transfer process, and finally fixed to the paper by the fixing unit to form the final printed output. To meet market needs, a toner cartridge with a fixing structure is required.

[0003] To facilitate installation, existing toner cartridges are typically aligned with the designated toner cartridge mounting position on a laser printer before being pushed into the toner compartment. This method often results in inaccurate alignment, and the existing toner cartridges do not provide adequate protection against toner detachment. This can lead to loose toner cartridges and affect print quality. Furthermore, the sealing performance of existing toner cartridges needs improvement, making it easy for toner to spill when adding it through the filling port. In addition, existing toner cartridges usually lack anti-static features, which can cause printer malfunctions due to static electricity. Utility Model Content

[0012] Preferably, the surface of the pull rod is equipped with anti-detachment clips, which are respectively engaged with the inner walls of the connecting cover plate and the fixing cover. The inner walls of the connecting cover plate and the fixing cover are each equipped with positioning blocks for preventing the toner compartment from loosening, and the positioning blocks are engaged with the surface of the toner compartment.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This toner cartridge with a fixed structure not only allows the toner compartment to be stably assembled inside the toner cartridge body during use, avoiding the phenomenon that the toner compartment is loose and affects the printing effect during use, but also makes the overall sealing of the toner cartridge higher, preventing spillage when the user adds toner through the toner filling port, making it more convenient to add toner, but also prevents static electricity between the toner cartridge and the printer during use, as the toner cartridge can discharge electrical energy and prevent the printer from malfunctioning due to static electricity;

[0014] 1. With a fixed anti-detachment mechanism, the user pulls the lever, causing it to slide inside the slot. This moves the anti-detachment clip away from the inner walls of the connecting cover and the fixed cover. The lever then moves the moving block to press the telescopic spring, causing the moving block to move towards the side of the spring. The user places the toner cartridge inside the toner cartridge body. The positioning clip automatically engages with the surface of the toner cartridge, positioning it correctly. After placement, the user releases the lever. The telescopic spring's elasticity resets the moving block, causing the lever to engage the anti-detachment clip with the inner walls of the connecting cover and the fixed cover. The moving block then engages with the surface of the toner cartridge, preventing it from shifting inside the toner cartridge body. This significantly improves the stability of the toner cartridge during use, achieving the function of fixing and preventing the toner cartridge from detaching. This ensures the toner cartridge is stably assembled inside the toner cartridge body, preventing printing issues caused by a loose toner cartridge.

[0015] 2. Equipped with a high-sealing mechanism, the sealing cover normally blocks the surface of the toner filling port. When toner needs to be added, the user rotates the sealing cover to move it away from the positioning clip. The user then adds toner through the filling port. After adding, the user rotates the sealing cover again, causing the sealing plug to move into the filling port. At this point, the positioning clip automatically engages with the inner wall of the sealing cover, and the sealing plug moves the rubber gasket to contact the inner wall of the filling port. The combined action of the sealing plug and the rubber gasket improves the seal between the sealing cover and the filling port, achieving a high-sealing function for the toner cartridge. This results in a higher overall sealing performance during use, preventing spillage when adding toner through the filling port and making toner filling more convenient.

[0016] 3. Equipped with an anti-static mechanism, the user places the conductive block on the surface of the placement slot. The user then pushes the conductive block, causing the guide slider to slide inside the fixed groove. The guide slider and the fixed groove work together to position the conductive block. Subsequently, the arc-shaped clip on the inner wall of the placement slot engages with the conductive block, securing it inside the slot and preventing it from detaching. The conductive block ensures conductivity, preventing static electricity and achieving the anti-static function of the toner cartridge. This prevents static electricity between the toner cartridge and the printer during use, allowing the toner cartridge to discharge electrical energy and preventing printer malfunctions due to static electricity.

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.

[0025] The present invention provides a toner cartridge with a fixed structure, as shown in the following structure: Figure 1 and Figure 2 As shown, the device includes a toner cartridge body 1, a connecting cover 101 mounted on the surface of the toner cartridge body 1, a fixing cover 102 mounted on the surface of the toner cartridge body 1 away from the connecting cover 101, a charging roller 104 mounted on the surfaces of the connecting cover 101 and the fixing cover 102, a cover 105 mounted on the surface of the toner cartridge body 1 by screws, a handle body 106 mounted on the surface of the cover 105, a toner compartment 107 disposed inside the toner cartridge body 1, a gear assembly 108 fitted on the surface of the toner compartment 107, and a toner filling port 103 opened on the surface of the cover 105, which is connected to the interior of the toner compartment 107.

[0026] Furthermore, such as Figure 2 and Figure 4As shown, a high-sealing mechanism 2 is provided on the surface of the cover 105 and the inner wall of the powder filling port 103. The high-sealing mechanism 2 includes a sealing cover 21, a sealing plug 22 and a high-sealing assembly 23. The high-sealing assembly 23 is provided on the surface of the cover 105 and the inner wall of the powder filling port 103. The high-sealing assembly 23 is composed of a rubber gasket 231 and a positioning clip 232. The surface of the cover 105 is provided with a sealing cover 21 for sealing and blocking the surface of the powder filling port 103. The sealing cover 21 and the surface of the cover 105 rotate and cooperate with each other. The inner wall of the sealing cover 21 is equipped with a sealing plug 22. One end of the sealing plug 22 extends into the interior of the powder filling port 103. The surface of the sealing plug 22 is adhered with a rubber gasket 231. The surface of the rubber gasket 231 contacts the inner wall of the gear assembly 108. The surface of the cover 105 is equipped with a positioning clip 232, which engages with the inner wall of the sealing cover 21.

[0027] In practice, the sealing cover 21 normally blocks the surface of the toner filling port 103. When toner needs to be added to the toner cartridge 107, the user rotates the sealing cover 21 on the surface of the cover 105, moving the sealing cover 21 away from the surface of the positioning clip 232. The user then adds toner to the toner cartridge 107 through the toner filling port 103. After adding toner, the user rotates the sealing cover 21 on the surface of the cover 105, causing the sealing cover 21 to move the sealing plug 22 into the toner filling port 103. At this time, the positioning clip 232 automatically engages with the inner wall of the sealing cover 21, and the sealing plug 22 moves the rubber pad 231 to contact the inner wall of the toner filling port 103. The combined action of the sealing plug 22 and the rubber pad 231 improves the sealing effect between the sealing cover 21 and the toner filling port 103, thus achieving a high sealing performance of the toner cartridge.

[0028] Furthermore, such as Figure 2 and Figure 5 As shown, the surface of the fixed cover 102 is provided with an anti-static mechanism 3. The interior of the anti-static mechanism 3 includes a placement groove 31, a conductive block 32, an arc-shaped clip 33, a guide slider 34, and a fixing groove 35. The surface of the fixed cover 102 is provided with a placement groove 31. The interior of the placement groove 31 is provided with a conductive block 32 for anti-static purposes. The surface of the conductive block 32 is provided with a guide slider 34. The inner wall of the fixed cover 102 is provided with a fixing groove 35. The surfaces of the fixing groove 35 and the guide slider 34 slide against each other. The inner wall of the placement groove 31 is provided with an arc-shaped clip 33 for preventing the conductive block 32 from loosening. The arc-shaped clip 33 and the inner wall of the conductive block 32 engage with each other.

[0029] During implementation, the user places the conductive block 32 on the surface of the placement groove 31. At this time, the user pushes the conductive block 32, which drives the guide slider 34 to slide inside the fixed groove 35. Under the combined action of the guide slider 34 and the fixed groove 35, the installation position of the conductive block 32 is positioned. Subsequently, the arc-shaped clip 33 on the inner wall of the placement groove 31 is engaged with the inside of the conductive block 32. Under the action of the arc-shaped clip 33, the conductive block 32 is installed inside the placement groove 31, preventing the conductive block 32 from coming loose from the inside of the placement groove 31. Under the action of the conductive block 32, it can conduct electricity and avoid static electricity, so as to achieve the anti-static function of the toner cartridge.

[0030] Furthermore, such as Figure 3 and Figure 6 As shown, a fixing and anti-detachment mechanism 4 is provided on the inner wall of the connecting cover 101 and the fixed cover 102 and on the surface of the toner hopper 107. The fixing and anti-detachment mechanism 4 includes a telescopic spring 41, a moving block 42 and a fixing and anti-detachment assembly 43. The fixing and anti-detachment assembly 43 is provided on the inner wall of the connecting cover 101 and the fixed cover 102 and on the surface of the toner hopper 107. The fixing and anti-detachment assembly 43 is composed of a groove 431, a pull rod 432, an anti-detachment clip 433 and a positioning clip 434. The inner walls of the connecting cover 101 and the fixed cover 102 are both provided with moving blocks 42. The moving blocks 42 slide and cooperate with the inner walls of the connecting cover 101 and the fixed cover 102 respectively. The moving blocks 42 are engaged with the surface of the toner hopper 107. The surface of the moving blocks 42 is equipped with a telescopic spring 41. 1. One end of the telescopic spring 41 is fixed to the inner wall of the fixed cover 102 and the powder filling port 103 respectively. A pull rod 432 is installed on the surface of the movable block 42. One end of the pull rod 432 extends to the outer side of the connecting cover 101 and the fixed cover 102 respectively. The inner walls of the connecting cover 101 and the fixed cover 102 are provided with grooves 431. The grooves 431 and the surface of the pull rod 432 slide against each other. An anti-detachment clip 433 is installed on the surface of the pull rod 432. The anti-detachment clip 433 is engaged with the inner walls of the connecting cover 101 and the fixed cover 102 respectively. The inner walls of the connecting cover 101 and the fixed cover 102 are both equipped with positioning blocks 434 for preventing the toner cartridge 107 from loosening. The positioning blocks 434 are engaged with the surface of the toner cartridge 107.

[0031] During implementation, the user pulls lever 432, causing it to slide inside the groove 431. At this time, lever 432 moves anti-detachment clip 433 away from the inner wall of connecting cover 101 and fixed cover 102. Lever 432 also moves moving block 42 to compress telescopic spring 41, causing moving block 42 to move towards one side of telescopic spring 41. The user places toner cartridge 107 inside toner cartridge body 1, and positioning clip 434 automatically engages with the surface of toner cartridge 107, positioning and installing the toner cartridge 107. After the toner cartridge 107 is placed, the user releases the lever 432. Under the elastic force of the telescopic spring 41, the moving block 42 is reset, causing the lever 432 to automatically engage the anti-detachment clip 433 with the inner wall of the connecting cover 101 and the fixed cover 102. At this time, the moving block 42 engages with the surface of the toner cartridge 107. Under the action of the moving block 42, the toner cartridge 107 is prevented from becoming loose inside the toner cartridge body 1, greatly improving the stability of the toner cartridge 107 during use, so as to achieve the function of fixing and preventing the toner cartridge 107 from detaching.

[0032] Working principle: In use, first place the toner cartridge body 1 in the designated position on the printer. The user pulls the lever 432, causing it to slide inside the slot 431. At this time, the lever 432 moves the anti-disengagement clip 433 away from the inner wall of the connecting cover 101 and the fixed cover 102. The lever 432 causes the moving block 42 to compress the telescopic spring 41, causing the moving block 42 to move to one side of the telescopic spring 41. The user places the toner cartridge 107 inside the toner cartridge body 1. The positioning clip 434 automatically locks onto the surface of the toner cartridge 107, positioning and installing the toner cartridge 107. After the toner cartridge 107 is placed, the user releases the lever 432. 2. Under the elastic force of the telescopic spring 41, the moving block 42 is reset, causing the pull rod 432 to automatically engage the anti-disengagement clip 433 with the inner wall of the connecting cover plate 101 and the fixed cover 102. At this time, the moving block 42 engages with the surface of the toner cartridge 107. Under the action of the moving block 42, the toner cartridge 107 is prevented from becoming loose inside the toner cartridge body 1, which greatly improves the stability of the toner cartridge 107 during use, so as to realize the function of fixing and preventing the toner cartridge 107 from being disengaged by the toner cartridge. This allows the toner cartridge 107 to be stably assembled inside the toner cartridge body 1 during use, avoiding the phenomenon that the toner cartridge 107 is loose and affects the printing effect during the use of the toner cartridge.

[0033] Subsequently, the sealing cap 21, in its normal state, blocks the surface of the toner filling port 103. When toner needs to be added to the toner cartridge 107, the user rotates the sealing cap 21 on the surface of the cover 105, causing the sealing cap 21 to move away from the surface of the positioning clip 232. The user then adds toner to the toner cartridge 107 through the toner filling port 103. After adding toner, the user rotates the sealing cap 21 on the surface of the cover 105, causing the sealing cap 21 to move the sealing plug 22 to the toner filling port 103. Inside 3, the positioning clip 232 automatically engages with the inner wall of the sealing cover 21, and the sealing plug 22 drives the rubber pad 231 to contact the inner wall of the toner filling port 103. Under the combined action of the sealing plug 22 and the rubber pad 231, the sealing effect between the sealing cover 21 and the toner filling port 103 is better, so as to achieve the function of high sealing performance of the toner cartridge. This makes the overall sealing performance of the toner cartridge higher during use, and the user will not spill toner when adding toner through the toner filling port 103, making it more convenient to add toner to the toner cartridge.

[0034] Subsequently, the user places the conductive block 32 on the surface of the placement slot 31. At this time, the user pushes the conductive block 32, which drives the guide slider 34 to slide inside the fixed slide groove 35. Under the combined action of the guide slider 34 and the fixed slide groove 35, the installation position of the conductive block 32 is positioned. Then, the arc-shaped clip 33 on the inner wall of the placement slot 31 is engaged with the inside of the conductive block 32. Under the action of the arc-shaped clip 33, the conductive block 32 is installed inside the placement slot 31, preventing the conductive block 32 from coming loose from the inside of the placement slot 31. Under the action of the conductive block 32, it can conduct electricity and avoid the phenomenon of static electricity, so as to realize the anti-static function of the toner cartridge. This prevents the phenomenon of static electricity between the toner cartridge and the printer when the toner cartridge is used. The toner cartridge can discharge electrical energy and avoid the phenomenon of the printer not working properly due to static electricity. Finally, the use of the toner cartridge is completed.
