A first guide section and a second guide section are provided on the end face of the guide ring facing the counting gear. An inclined section is provided between the second guide section and the first guide section.

[0004] Currently, traditional refillable toner cartridges with a quick reset structure have a problem: when filling toner cartridges with toner vials, the toner's low fluidity makes it easy for it to clog the toner tubes, making the filling process difficult. Utility Model Content

[0005] The purpose of this invention is to provide an easy-refill toner cartridge with a quick-reset structure, in order to solve the problem mentioned in the background art that, during the use of existing easy-refill toner cartridges with quick-reset structures, the toner is prone to clogging in the toner tube of the toner bottle due to its low fluidity, making the toner filling operation difficult.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a base is included, the inner wall of the base is provided with a placement groove, the two sides of the base are provided with mounting grooves, a clamping mechanism is fixedly connected to one side of the inner wall of the mounting groove, a toner cartridge body is movably connected to the inner bottom wall of the placement groove, a cover plate is bolted to the upper end of the base, a sponge pad is glued to the lower end of the cover plate, and a feeding mechanism is fixedly connected to one side of the upper end of the toner cartridge body.

[0007] The clamping mechanism includes a spring, one side of which is fixedly connected to the inner wall of the mounting groove. A pressing shell is provided on the other side of the spring. A toothed plate is provided in the middle of one side of the pressing shell. A gear is meshed with one side of the toothed plate. A rotating rod is inserted into the middle of the gear. A toothed plate is meshed with one side of the outer wall of the gear. A clamping plate is fixedly connected to one end of the toothed plate. A storage groove is embedded in the middle of one side of the clamping plate. A spring is fixedly connected to one side of the clamping plate.

[0008] Preferably, the other side of the spring is fixedly connected to one side of the pressing shell around the perimeter, and the middle part of one side of the pressing shell is fixedly connected to one side of the toothed plate.

[0009] Preferably, one side of the clamping plate extends through the mounting groove to the inner wall of the placement groove and is in close contact with one side of the toner cartridge body.

[0010] Preferably, the outer wall of the placement groove is embedded and connected to the inner wall of the base, and one side of the mounting groove is embedded and connected to both sides of the base.

[0011] Preferably, the feeding mechanism includes a through hole, the outer wall of which is connected through to one side of the upper end of the drum body, a sealing cover is provided on the inner wall of the through hole, a toggle plate is provided on the inner wall of the sealing cover, a fixing tube is fixedly connected to the lower edge of the through hole, an annular groove is formed on the inner wall of the fixing tube, a spring is fixedly connected to the bottom wall of the annular groove, an annular plate is fixedly connected to the upper end of the spring, and a movable tube is fixedly connected to the inner side wall of the annular plate.

[0012] Preferably, the inner wall of the through hole is threadedly connected to the outer wall of the sealing cover, and the two sides of the inner wall of the sealing cover are fixedly connected to the two sides of the actuating plate.

[0013] Preferably, the inner wall of the annular plate is fitted onto the bottom of the outer wall of the movable tube, and the structure is integrally formed.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The clamping mechanism allows for quick and secure positioning and clamping of the toner cartridge during installation, effectively preventing displacement caused by shaking or vibration during use. When installing the toner cartridge into the base's placement slot, simply place the cartridge in the slot. The pressing shell is then compressed, causing toothed plate one to move. Toothed plate one drives a gear to rotate, which in turn moves toothed plate two, causing the clamping plate to move towards the toner cartridge until they are tightly fitted together, thus securing the cartridge. To remove the cartridge, simply reverse the pressing shell operation. The spring force of spring one will reset the pressing shell, releasing the clamping mechanism and facilitating removal. This clamping mechanism is simple in structure and easy to operate, greatly improving the efficiency of toner cartridge installation and removal, while also enhancing the stability of the cartridge during use.

[0016] 2. The specially designed feeding mechanism effectively prevents clogging during toner filling, improving the smoothness of the filling operation. When filling is required, first, the sealing cap is opened by rotating the lever to expose the through-hole. Then, the toner bottle's nozzle is inserted into the through-hole, allowing the toner to enter the fixed tube. Inside the fixed tube, the movable tube moves downwards under the impact of the toner, simultaneously compressing spring three. Once the toner has filled to a certain level, the toner bottle is removed, and the movable tube returns to its original position under the elastic force of spring three, pushing any remaining toner in the fixed tube into the drum unit, preventing toner accumulation and clogging. Furthermore, the combination of the annular groove and the annular plate makes the movable tube more stable during its up-and-down movement, further ensuring the smoothness of the filling process. This feeding mechanism not only solves the clogging problem of traditional drum filling but also improves filling efficiency and reduces operational difficulty. Attached Figure Description

[0027] Working Principle: First, the toner cartridge body 5 is placed inside the placement slot 2. Since the outer wall of the placement slot 2 is embedded and connected to the inner wall of the base 1, the stability of the toner cartridge body 5 is ensured. Next, the clamping mechanism 4 is operated, pressing the pressing shell 42. The pressing shell 42 drives the toothed plate 43 to move. The toothed plate 43 drives the gear 44, which meshes with it, to rotate around the rotating rod 45. The rotation of the gear 44 drives the toothed plate 46 to move, which in turn drives the clamping plate 47 to move away from the toner cartridge body 5 until the clamping plate 47 disengages from one side of the toner cartridge body 5. At this time, springs 41 and 49 are in a compressed state. Under the elastic force of springs 41 and 49, the toner cartridge body 5 is automatically fixed, preventing it from shaking during use. When toner needs to be added, the sealing cover 82 in the feeding mechanism 8 is rotated to seal the cartridge. The cover 82 is threaded to the inner wall of the through hole 81. The sealing cover 82 can be opened by rotating it. After the sealing cover 82 is opened, toner is added into the drum body 5 through the through hole 81. During the adding process, due to the setting of the spring 86, the annular plate 87 and the movable tube 88 on the bottom wall of the annular groove 85 in the fixed tube 84 of the feeding mechanism 8, the movable tube 88 can move appropriately in the fixed tube 84 according to the toner addition, ensuring the smoothness of toner addition. After adding toner, the sealing cover 82 is rotated in the opposite direction to close it, preventing external impurities from entering the drum body. When it is necessary to disassemble the drum body 5, press the pressing shell 42 to loosen the clamping plate 47 from clamping the drum body 5, and the drum body 5 can be taken out from the placement slot 2. The whole process is simple to operate. The setting of the clamping mechanism 4 and the feeding mechanism 8 effectively improves the efficiency and convenience of using the drum.

[0028] Then, through the coordinated work of clamping mechanism 4 and feeding mechanism 8, not only is the stable installation of the drum body 5 on the base 1 ensured, but the toner addition process is also made smoother and more efficient. Under the action of clamping mechanism 4, the drum body 5 is firmly fixed in the placement slot 2, avoiding printing quality problems caused by shaking. At the same time, the feeding mechanism 8 is designed so that the feeding channel can be easily opened by rotating the sealing cover 82. When adding toner, the movable tube 88 can move appropriately according to the actual situation under the action of spring 86, effectively preventing toner blockage and ensuring the smoothness of the addition process. After adding, rotating the sealing cover 82 again closes the feeding channel, which can prevent external impurities from entering the drum, protecting the cleanliness and normal use of the drum. The whole device has a compact structure and is easy to operate, greatly improving the efficiency and convenience of using the drum and bringing great convenience to the user's printing work. The above is the working process of the whole device, and the contents not described in detail in this manual are all prior art known to those skilled in the art.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
