The user pulls the removal cover away from the second side cover, causing it to move the positioning block away from the positioning slot. At this point, the elastic clip is squeezed away from the inside of the removal cover, thus removing the cover from the surface of the second side cover and connecting rod. The user then removes the photosensitive drum from the waste toner compartment and the drum casing, and pulls it down to remove it from the waste toner compartment for replacement. This achieves quick replacement of the photosensitive drum in the toner cartridge structure, making it more convenient for users to remove and replace the drum, and preventing wear and tear that makes replacement difficult.

[0016] 3. By incorporating a sealing and leak-proof toner mechanism, users add toner into the toner cartridge through the toner filling port. After filling, the user places the sealing plug on the surface of the filling port, causing it to move inside. This movement of the sealing plug, along with the retaining ring and rubber pad, brings the silicone pad into contact with the inner wall of the filling port. The combined action of the retaining ring, rubber pad, and silicone pad seals the filling port and the sealing plug, preventing toner from leaking out of the cartridge. This achieves a leak-proof sealing function, preventing accidental toner leakage during use and ensuring better printing quality. Furthermore, it enhances the overall sealing performance of the toner cartridge structure. Attached Figure Description

[0027] The present invention provides a toner cartridge structure that is easy to pick up and put away, as shown in the following figure. Figure 1 and Figure 2As shown, the device includes a toner cartridge body 1, a waste toner compartment 101 on one side of the toner cartridge body 1, mounting plates 103 on the surface of the toner cartridge body 1, and fastening bolts 104 threaded onto the surface of the mounting plates 103. One end of each fastening bolt 104 passes through the mounting plate 103 and is threaded onto the surface of the waste toner compartment 101. A toner cartridge shell 102 is mounted on the surface of the toner cartridge body 1, and a toner filling port 105 is provided on the surface of the toner cartridge body 1. A photosensitive drum 106 is disposed inside the waste toner compartment 101, and the photosensitive drum 106 rotates with the inner wall of the waste toner compartment 101. A connecting rod 107 is mounted on the surface of the photosensitive drum 106. A first side cover 109 is screwed onto the surfaces of the toner cartridge body 1 and the waste toner compartment 101. A second side cover 112 is provided on the surfaces of the toner cartridge body 1 and the waste toner compartment 101.

The waste toner hopper 101 is equipped with a developing roller 110 and a charging roller 111. The developing roller 110 and the charging roller 111 are respectively rotatably engaged with the inner wall of the waste toner hopper 101. The waste toner hopper 101 is equipped with a sponge roller and a transfer roller. The transfer roller is located below the photosensitive drum 106, and the transfer roller and the sponge roller are respectively rotatably engaged with the inner wall of the waste toner hopper 101.

[0028] Furthermore, such as Figure 4 and Figure 6 As shown, the surface of the toner cartridge housing 102 is provided with an easy-to-use mechanism 2, which consists of a mounting handle 21, a mounting bracket 22, and an easy-to-use assembly 23. The easy-to-use assembly 23 is located on the surface of the toner cartridge housing 102 and consists of a fastening stud 231 and an anti-detachment sleeve 232. The surface of the toner cartridge housing 102 is provided with a mounting handle 21, and a mounting bracket 22 is mounted on the surface of the mounting handle 21. The mounting bracket 22 and the surface of the toner cartridge housing 102 are engaged with each other. An anti-detachment sleeve 232 is mounted on the surface of the mounting handle 21, and a fastening stud 231 is threadedly connected to the surface of the anti-detachment sleeve 232. One end of the fastening stud 231 passes through the anti-detachment sleeve 232 and the mounting handle 21 in sequence and is threadedly fastened to the surface of the toner cartridge housing 102. The fastening stud 231 and the anti-detachment sleeve 232 cooperate with each other.

[0029] In practice, the user places the installation handles 21 on the surface of the toner cartridge housing 102, causing the installation handles 21 to engage with the mounting brackets 22 on the surface of the toner cartridge housing 102. The user then tightens the fastening studs 231 on the surface of the installation handles 21. Under the action of the fastening studs 231, the installation handles 21 are installed on the surface of the toner cartridge housing 102. The anti-loosening sleeves 232 prevent the fastening studs 231 from loosening, thereby further improving the stability of the installation handles 21 when installed on the surface of the toner cartridge housing 102. The installation handles 21 make it easier for the user to handle and remove the toner cartridge structure, making it easier for the user to grasp, reducing hand pressure, and improving the convenience of handling, thus realizing the function of easy handling of the toner cartridge structure.

[0030] Furthermore, such as Figure 4 and Figure 7 As shown, the surfaces of the second side cover 112 and the disassembly cover 113 are provided with a quick replacement mechanism 3. The quick replacement mechanism 3 consists of a fixing frame 31, a positioning slot 32, a positioning block 33, and an elastic clip 34. The surface of the connecting rod 107 is equipped with an elastic clip 34, which engages with the inner wall of the disassembly cover 113. The inner wall of the disassembly cover 113 is equipped with a positioning block 33. The surface of the second side cover 112 is provided with a positioning slot 32, which engages with the surface of the positioning slot 32 and the surface of the positioning block 33. The surface of the photosensitive drum 106 is equipped with a fixing frame 31. One end of the disassembly cover 113 passes through the fixing frame 31 and extends to the outside of the fixing frame 31. The positioning slot 32 engages with the surface of the disassembly cover 113.

[0031] In practice, after prolonged use, the surface of the photoconductor drum 106 is prone to wear, affecting the printer's print quality. The user pulls the disassembly cover 113 away from the side cover 112, causing the disassembly cover 113 to move the positioning block 33 away from the inside of the positioning slot 32. At this time, the elastic clip 34 is squeezed away from the inside of the disassembly cover 113, thereby removing the disassembly cover 113 from the surface of the second side cover 112 and the connecting rod 107. The user then removes the photoconductor drum 106 from the surface of the waste toner compartment 101 and the drum housing 102, and then pulls the photoconductor drum 106 downwards to remove it from the inside of the waste toner compartment 101 for replacement. This achieves the function of quickly replacing the photoconductor drum 106 in the drum structure.

[0032] Furthermore, such as Figure 5 and Figure 8As shown, a sealing and leak-proof powder mechanism 4 is provided on the surface of the powder filling port 105. The sealing and leak-proof powder mechanism 4 consists of a sealing plug 41, a silicone pad 42, a fixing ring 43, and a rubber pad 44. The surface of the powder filling port 105 is provided with a sealing plug 41 for sealing the powder filling port 105. One end of the sealing plug 41 extends into the interior of the powder filling port 105. The inner wall of the sealing plug 41 is wrapped with a fixing ring 43. The surface of the fixing ring 43 is adhered with a rubber pad 44. The surface of the rubber pad 44 away from the fixing ring 43 is wrapped with a silicone pad 42 for sealing and preventing powder leakage between the sealing plug 41 and the powder filling port 105. The inner wall of the silicone pad 42 is in contact with the inner wall of the powder filling port 105.

[0033] During implementation, the user adds toner into the toner compartment of the drum body 1 through the toner filling port 105. After adding toner, the user places the sealing plug 41 on the surface of the toner filling port 105, causing the sealing plug 41 to move into the interior of the toner filling port 105. The sealing plug 41 drives the fixing ring 43, the rubber pad 44 and the fixing ring 43 to move, causing the silicone pad 42 to move to contact the inner wall of the toner filling port 105. Under the combined action of the fixing ring 43, the rubber pad 44 and the silicone pad 42, the toner filling port 105 and the sealing plug 41 are sealed, preventing the toner inside the toner compartment of the drum body 1 from leaking out between the toner filling port 105 and the sealing plug 41, thus achieving the function of sealing the drum structure to prevent toner leakage.

[0034] Working principle: In use, first place the toner cartridge body 1 on one side of the waste toner compartment 101, causing the toner cartridge body 1 to move the mounting plate 103 to the side of the waste toner compartment 101. The user tightens the fastening bolts 104 on the surface of the mounting plate 103. Under the combined action of the mounting plate 103 and the fastening bolts 104, the toner cartridge body 1 and the waste toner compartment 101 are installed. Then, the user places the installation handles 21 on the surface of the toner cartridge housing 102, causing the installation handles 21 to move the mounting bracket 22 to the surface of the toner cartridge housing 102. The user then tightens the fastening studs 231 on the surface of the installation handles 21. Under the action of the mounting handle 21, the mounting handle 21 is installed on the surface of the toner cartridge housing 102. Under the action of the anti-loosening screw sleeve 232, the fastening screw 231 can be prevented from loosening, thereby further improving the stability of the mounting handle 21 when it is installed on the surface of the toner cartridge housing 102. Under the action of the mounting handle 21, it is more convenient for users to operate when taking out and putting in the toner cartridge structure. It is easier for users to grasp, reduces hand pressure, and improves the convenience of taking out and putting in, so as to realize the function of easy to take out and put in the toner cartridge structure. This makes it easier for users to put the toner cartridge structure into the printer for use, making the toner cartridge structure more convenient to operate when in use.

[0035] Subsequently, a negative charge is applied to the surface of the photosensitive drum 106 under the action of the charging roller 111. The laser, according to the shape of the printed pattern, irradiates the photosensitive drum 106, and the irradiated areas of the photosensitive drum 106 become positively charged. Since the photosensitive drum 106 is a photosensitive element, the irradiated areas will become positively charged. Toner enters the surface of the photosensitive drum 106, and under the action of the developing roller 110, the toner adheres to the heavily charged surface of the photosensitive drum 106. The negatively charged areas on the surface of the photosensitive drum 106 are ignored by the toner. The sponge roller inside the waste toner bin 101 provides toner to the surface of the developing roller 110 and cleans up any toner that has not been adsorbed onto the photosensitive drum 106. Since the surface of the transfer roller inside the waste toner bin 101 is negatively charged, it can adsorb the toner attached to the photosensitive drum 106 onto the paper. The toner attached to the paper is heated by the heating roller and squeezed by the pressure roller, and then printed onto the surface of the paper. Under the action of the toner scraper 108, excess toner on the surface of the photosensitive drum 106 can be cleaned off and the toner is cleaned into the interior of the waste toner bin 101.

[0036] Subsequently, after prolonged use, the surface of the photoconductor drum 106 is prone to wear, affecting the printer's print quality. The user pulls the disassembly cover 113 away from the side of the second side cover 112, causing the disassembly cover 113 to move the positioning block 33 away from the inside of the positioning slot 32. At this time, the elastic clip 34 is squeezed away from the inside of the disassembly cover 113, thereby removing the disassembly cover 113 from the surface of the second side cover 112 and the connecting rod 107. The user then removes the photoconductor drum 106 from the surface of the waste toner compartment 101 and the drum housing 102, and pulls the photoconductor drum 106 downwards to remove it from the inside of the waste toner compartment 101 for replacement. This enables the quick replacement of the photoconductor drum 106 in the drum structure, making it more convenient for users to remove and replace the photoconductor drum 106 during use, and preventing the photoconductor drum 106 from becoming worn and difficult to replace.

[0037] Subsequently, the user adds toner into the toner compartment of the drum body 1 through the toner filling port 105. After adding toner, the user places the sealing plug 41 on the surface of the toner filling port 105, causing the sealing plug 41 to move into the interior of the toner filling port 105. The sealing plug 41 drives the fixing ring 43 and the rubber pad 44 to move, causing the silicone pad 42 to move to contact the inner wall of the toner filling port 105. Under the combined action of the fixing ring 43, the rubber pad 44 and the silicone pad 42, a seal is formed between the toner filling port 105 and the sealing plug 41, preventing toner from leaking out from the toner compartment of the drum body 1. This achieves the function of sealing and preventing toner leakage in the drum structure, thus preventing accidental leakage of toner from the toner compartment during use and affecting the printing effect. At the same time, it makes the overall sealing of the drum structure higher during use, and finally completes the use of the drum structure.

[0038] 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.
