[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1-Figure 3 The utility model provides an embodiment: a moisture-proof toner cartridge, comprising a box body 1, a drying chamber 20 is provided inside the box body 1, a sealing groove 15 is provided on the inner wall of the drying chamber 20, two fixing blocks 4 are fixedly connected to the top of the box body 1, a fixing groove 8 is provided inside the fixing block 4, a cover plate 2 is slidably connected to the top of the box body 1, a sealing gasket 10 is fixedly connected to the bottom of the cover plate 2, connecting grooves 14 are provided on both sides of the top of the cover plate 2, a connecting rod 9 is slidably connected to the inside of the connecting groove 14, and a push block 16 is fixedly connected to the outside of the connecting rod 9, One end of the connecting rod 9 is fixedly connected to a spring 22, the outer right side of the box body 1 is fixedly connected to a feed pipe 7, a sealing groove 19 is provided inside the feed pipe 7, a material port cover 5 is slidably connected to the inside of the feed pipe 7, a sealing gasket 17 is fixedly connected to the outside of the material port cover 5, a card slot 18 is provided on one side of the material port cover 5, a fixing component is installed on the outer right side of the box body 1, one end of the spring 22 is fixedly connected to the inner wall of the connecting groove 14, the outside of the spring 22 is slidably connected to the inside of the connecting groove 14, and one end of the connecting rod 9 is slidably connected to the inner wall of the fixing groove 8.

[0033] Specifically, the function of the drying chamber 20 is that when the moisture-proof material needs to be replaced, the user only needs to open the drying chamber 20, take out the old moisture-proof material and replace it with a new one, without disassembling the entire toner cartridge. The design of the push block 16 and the connecting rod 9 enables the user to easily open or close the upper cover 2 of the drying chamber 20 in the toner cartridge. By pushing the push block 16, the connecting rod 9 will move accordingly, thereby controlling the opening and closing of the cover 2. This design makes the operation simple and intuitive, without the need for complicated steps or tools. The function of the spring 1 21 is to provide a stable restoring force to ensure that the connecting rod 9 can be firmly stuck in the fixing groove 8. When the push block 16 is pushed, the spring 1 21 will be compressed, and when the external force disappears, the spring 1 21 will return to its original state, pushing the connecting rod 9 back to its original position. This design ensures that the cover 2 can fit tightly when closed to prevent toner leakage or external moisture intrusion.

[0034] Reference Figure 3 , Figure 5 , Figure 6The fixing assembly includes a fixing plate 6, one end of which is fixedly connected to the outer right side of the box body 1, a connecting groove 12 is opened inside the fixing plate 6, and a connecting plate 13 is slidably connected inside the connecting groove 12, and the outside of the connecting plate 13 is fixedly connected to the telescopic rod 11, and a spring 21 is sleeved on the outside of the telescopic rod 11, and a card block 23 is fixedly connected to the outside of the connecting plate 13, one end of the card block 23 is inserted into the inner wall of the card groove 18, and the card block 23 is plugged and matched with the card groove 18, and the longitudinal section of the card block 23 is set to be square, the sealing gasket 17 matches the sealing groove 19, and the sealing gasket 17 is arranged inside the sealing groove 19, one end of the spring 21 is fixedly connected to the outside of the connecting plate 13, and the other end of the spring 21 is fixedly connected to the inner wall of the connecting groove 12, the outside of the spring 21 is slidably connected to the inside of the connecting groove 12, and the other end of the telescopic rod 11 is fixedly connected to the inside of the connecting groove 12.

[0035] Specifically, the design of the connecting groove 12 helps prevent problems caused by looseness or misalignment of the telescopic rod 11, spring 1 21 and other structures. The combination of the telescopic rod 11 and the spring 1 21 provides a stable fixing force for the block 23. When the block 23 is inserted into the card slot 18, the telescopic rod 11 maintains a certain extension length, while the spring 1 21 is in a compressed state, providing a continuous and stable restoring force. This restoring force ensures that the block 23 can be firmly retained in the card slot 18 and is not easily removed due to external vibration or impact, thereby ensuring a stable connection between the feed port cover 5 and the feed pipe 7. The close combination of the sealing pad 2 17 and the sealing groove 2 19 can form an effective sealing barrier to prevent external moisture, dust and other impurities from entering the interior of the toner cartridge. This is crucial to maintaining a dry environment inside the toner cartridge, because moisture may cause toner to clump or deteriorate, thereby affecting the print quality and the stable operation of the printer.

[0036] Reference Figure 1 , Figure 2 The sealing gasket 10 matches the sealing groove 15, and the sealing gasket 10 is arranged inside the sealing groove 15. A mounting groove 24 is opened at the middle end of the top of the cover plate 2, and a handle 3 is rotatably connected inside the mounting groove 24.

[0037] Specifically, the tight combination of the sealing gasket 10 and the sealing groove 15 forms an efficient sealing system, which ensures that the moisture-proof material in the installation cavity can function in a dry and sealed environment. This sealing can prevent external moisture from invading the installation cavity, thereby maintaining the hygroscopic properties of the moisture-proof material and ensuring that it continuously and effectively prevents the toner from getting wet. By operating the cover plate 2 with the handle 3, the user can perform maintenance operations on the toner cartridge more safely. Compared with directly operating the cover plate 2 by hand, the handle 3 provides a more stable grip point, reducing accidents caused by slipping hands or improper operation. This helps protect the user's hands and reduces safety risks caused by operating errors.

[0038] Working principle: When it is necessary to clean or add powder to the toner cartridge, first push the connecting plate 13 to make the block 23 detach from the inside of the card slot 18, then buckle the material port cover 5 from the feed pipe 7, then pour the waste powder through the feed pipe 7, then add new toner to the inside of the box body 1 through the feed pipe 7, and then cover the feed pipe 7 with the material port cover 5, and finally release the connecting plate 13, and under the elastic force of the telescopic rod 11 and the spring 1 21, the block 23 is clamped into the inside of the card slot 18, so as to achieve the safety and stability of the toner cartridge. Through the firm buckle fixation, the fixed cover on the feed port of the toner cartridge is not easy to loosen or fall off during transportation, storage and use, reducing the risk of toner leakage caused by accidental falling off. It not only helps to protect the internal components of the printer from contamination and damage, but also reduces the safety risks that users may encounter during use.

[0039] When replacing the moisture-proof material, by simultaneously pushing the two push blocks 16 in the direction of the handle 3, the connecting rod 9 is driven to move simultaneously, so that the connecting rod 9 is separated from the interior of the fixed groove 8, and then the handle 3 is pulled to separate the cover plate 2 from the interior of the drying chamber 20, and then the moisture-proof material that needs to be replaced in the drying chamber 20 is taken out, and replaced with a new moisture-proof material after taking it out, and then the cover plate 2 is covered into the interior of the drying chamber 20. The working principle is not explained in detail above, wherein the spring 22 is in a compressed state, so that the connecting rod 9 is better stuck in the interior of the fixed groove 8. In this way, the moisture-proof material can be replaced without going through a complicated disassembly and assembly process. This not only reduces the difficulty of maintenance, but also reduces the risk of damage caused by improper operation.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
