[0024] Figure 5 This is a schematic diagram of the structure of the toner cartridge of this utility model. Detailed Implementation

[0025] The present invention will now be described in detail with reference to specific embodiments.

[0026] Example 1: As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a portable, detachable toner cartridge with a toner cap structure includes a main body 1 and a top body 2. The main body is cylindrical, and a ring 3 is provided on the outer side of the main body. The main body is located in the ring, and the ring 3 is integrated with the main body 1. The main body and the ring are made of plastic. The top body 2 is located at the top of the main body, and the top surface of the top body has an inwardly recessed countersunk hole 4. A pull ring 5 is provided in the countersunk hole 4, and the two ends of the pull ring 5 are connected to the inner wall of the countersunk hole. The top body and the pull ring are made of plastic.

[0027] The pull ring has a bend 6. The bend allows for easy hooking by hand, and after deformation, the powder filling cap can be pulled out directly.

[0028] There is a gap between the bend and the inner wall of the countersunk hole.

[0029] Working Principle: The pull ring of this invention is located inside the countersunk hole, occupying no additional space. Its placement behind the toner filler cap structure does not affect the toner filler cap's placement within the toner cartridge, nor does it occupy additional space in the toner cartridge. Compared to existing technologies, ordinary consumers can easily pull out the toner filler cap structure using the pull ring, making toner addition convenient and user-friendly. No special tools or personnel are required. After adding toner, the toner filler cap structure is reinstalled, and the pull ring returns to the countersunk hole when the consumer releases it.

[0030] Example 2: In this example, the bend 6 is arc-shaped. This facilitates manufacturing. The rest is the same as in Example 1.

[0031] Example 3: In this example, the two ends of the pull ring are left end 51 and right end 52, respectively. The left end has a left straight strip and the right end has a right straight strip.

[0032] The left and right straight segments are located on the same diameter within the countersunk hole. The presence of these left and right straight segments facilitates the deformation of the pull ring, making it easier to hook out and improving ease of operation for consumers. The rest is the same as in Example 1 or Example 2.

[0033] Example 4: In this example, there are two rings 3, with a gap between them. This facilitates sealing with the opening.

[0034] The bottom end face of the main body has an opening, and the main body has a cavity inside, which communicates with the opening. The rest is the same as in Embodiment 1, Embodiment 2, or Embodiment 3.

[0035] Example 5: Figure 5 As shown, a toner cartridge includes a main frame 201, a photosensitive drum, and a toner container 202. The photosensitive drum and toner container are mounted on the main frame, and the toner container is located in an opening. It also includes a portable, detachable toner cartridge cover structure 203, which includes a main body and a top body. The main body is cylindrical, with a ring on its outer surface. The main body is located within the ring, and the ring is integrally connected to the main body. The main body and the ring are both made of plastic. The top body is located at the top of the main body, and its top surface has an inwardly recessed countersunk hole. A pull ring is located within the countersunk hole, and both ends of the pull ring are connected to the inner wall of the countersunk hole. The top body and the pull ring are both made of plastic. The main body is placed in the opening, with the ring in close contact with the inner wall of the opening, and the top body protruding outside the opening.

[0036] Compared to existing technologies, this toner cartridge allows ordinary consumers to easily pull out the toner filler using a pull ring, making toner addition convenient and user-friendly. It requires no special tools or personnel and does not affect the original shape of the toner cartridge.

[0037] Alternatively, in this example, the portable and detachable toner cartridge filling cap structure can also adopt the portable and detachable toner cartridge filling cap structure in any one of the embodiments 1 to 4.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
