[0021] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0022] Embodiment 1

[0023] Combined with Figure 1 , Attachment Figure 2 and attached Figure 3 A moisture-proof toner cartridge comprises a box body 1, a plurality of through holes 101 are provided at the upper end of the box body 1, a threaded tube 2 is installed at the upper end of the through hole 101, a venting barrel 3 is inserted on the through hole 101, a rebound component 4 is installed on the inner bottom wall of the venting barrel 3, a desiccant bag 5 is placed at the upper end of the rebound component 4, and a pressure cover component 6 acting on the desiccant bag 5 is connected to the inner thread of the threaded tube 2.

[0024] In combination with the above structure, the air-permeable barrel 3 is located in the box body 1, so that the desiccant bag 5 is located in the box body 1, thereby achieving moisture-proof treatment of the box body 1, namely the toner cartridge.

[0025] Combined with Figure 2 and attached Figure 3 The inner diameter of the threaded tube 2 is larger than the diameter of the through hole 101. The upper end of the air-permeable barrel 3 is provided with a lap ring 7 overlapped on the upper end of the through hole 101. The air-permeable barrel 3 is provided with a plurality of equidistant air holes 301 for easy ventilation, so that the desiccant bag 5 can function.

[0026] In combination with the above structure, the air-permeable barrel 3 is inserted through the overlapping ring 7 and overlapped on the upper end of the through hole 101, so that the air-permeable barrel 3 is easy to take out and place, and is easy to maintain.

[0027] Embodiment 2

[0028] Based on the first embodiment, combined with the attached Figure 3 The resilient assembly 4 includes a telescopic rod 8 mounted on the inner bottom wall of the air-permeable barrel 3, a placement plate 9 is fixed on the upper end of the telescopic rod 8, a spring 10 is connected to the outer sleeve of the telescopic rod 8 between the inner bottom wall of the air-permeable barrel 3 and the placement plate 9, and the desiccant bag 5 is placed on the upper end of the placement plate 9. The cover plate 11 is combined with the above structure. When the desiccant bag 5 needs to be replaced, it is only necessary to unscrew the gland assembly 6. Under the reset action of the spring 10, the telescopic rod 8 is extended, so that the placement plate 9 pushes the upper end of the desiccant bag 5 out of the air-permeable barrel 3. It is convenient to take out and replace the desiccant bag 5 without using tools such as tweezers; the telescopic rod 8 includes a sleeve fixed on the inner bottom wall of the air-permeable barrel 3, a protruding rod fixed on the lower end of the placement plate 9, and other components. The protruding rod slides up and down in the sleeve.

[0029] Combined with Figure 2 The gland assembly 6 includes a cover plate 11 threadedly connected to the threaded tube 2, a shaft 12 is connected to the lower end of the cover plate 11, a pressure plate 13 in contact with the upper end of the desiccant pack 5 is fixed to the lower end of the shaft 12, and a rotary vane 14 is fixed to the upper end of the cover plate 11. The outer side of the cover plate 11 and the inner side of the threaded tube 2 are respectively provided with a threaded external thread 1101 and an internal thread 201.

[0030] Combined with the above structure, after the desiccant bag 5 is placed in the breathable barrel 3, the pressing plate 13 of the pressure cover assembly 6 is placed in the breathable barrel 3, and the cover plate 11 is inserted into the threaded tube 2 by rotating the rotary vane 14, and the pressing plate 13 is pressed on the desiccant bag 5 and descends.

[0031] The specific usage is as follows:

[0032] When the desiccant bag 5 needs to be replaced, it is only necessary to unscrew the gland assembly 6. Under the resetting action of the spring 10, the telescopic rod 8 is extended, so that the placement plate 9 pushes the upper end of the desiccant bag 5 out of the air-permeable barrel 3. The desiccant bag 5 can be taken out and replaced without using tools such as tweezers, which is more convenient. Since the air-permeable barrel 3 is inserted through the lap ring 7 and overlapped on the through hole 101, it is only necessary to unscrew the gland assembly 6 to take out the air-permeable barrel 3, which is convenient for maintenance and prevents the air holes from being blocked.

[0033] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
