Description

Technical Field

[0001] This application relates to the field of toner cartridge technology, and more particularly to a moisture-proof toner cartridge. Background Technology

[0002] The toner cartridge is a key component of a laser printer. It mainly consists of a photosensitive drum, a magnetic roller, and a toner cartridge. Its working principle is that the photosensitive drum is charged and irradiated by a laser, forming an electrostatic latent image on its surface. Then, the magnetic roller picks up the toner that has fallen from the toner cartridge and makes the toner rubbed and become charged. The electrostatic latent image on the surface of the photosensitive drum then attracts the charged toner on the magnetic roller to form a toner image. Finally, the photosensitive drum comes into contact with the printing paper and prints the toner image on the paper.

[0003] The existing toner cartridge and toner box are separate, which allows the toner in the toner box to be replenished in time when it runs out, thereby reducing printing costs. However, in the existing technology, the sealing of the toner filling point is poor and it is easy to get clogged when filling. The filling is also not convenient and quick. Therefore, we have proposed a moisture-proof toner cartridge. Utility Model Content

[0031] like Figures 1-4 As shown in the figure, this application embodiment provides a moisture-proof toner cartridge, including:

[0032] The toner cartridge body 1 has a feeding port 2 at the upper middle part of the toner cartridge body 1. A sealing plug 3 is threaded into the inside of the feeding port 2, and a limiting ring 4 is fixedly provided at the lower end of the inner cavity of the feeding port 2.

[0033] The inner cavity of the toner cartridge body 1 is fixedly connected to the feed port 2 below the feed port 2, and a spiral feed rod 7 is rotatably provided in the lower part of the inner cavity of the feed port 6.

[0034] The inner side wall of the toner cartridge body 1 and the lower part of the limiting ring 4 are provided with a connecting groove 11, and a moisture-proof baffle 9 is rotatably connected to the upper end of the inner cavity of the connecting groove 11 via a connecting shaft 15. The right end of the limiting ring 4 is respectively limited and inserted with a push rod 18 on the left and right sides of the moisture-proof baffle 9 and a pressure rod 12 is inserted through and limited.

[0035] Moisture-proof baffle 9 is located at the right end of the feed housing 6.

[0036] Specifically: The toner cartridge body 1 adopts the existing toner cartridge structure on the market, which is existing technology. This application improves the toner cartridge feeding part.

[0037] like Figure 2 and Figure 4 As shown, the inner wall of the feed housing 6 is inclined toward the spiral feed rod 7, and the lower end of the inner cavity of the feed housing 6 is also inclined. The right end of the feed housing 6 is open.

[0038] The left side of the spiral feed rod 7 is inserted into the lower left side of the feed housing 6 via a bearing, and a drive motor 8 is fixedly connected to the left end of the spiral feed rod 7. The drive motor 8 is fixedly connected to the left end of the feed housing 6. The right end of the spiral feed rod 7 is inserted into the positioning block 10 via a bearing, and the lower end of the positioning block 10 is fixedly connected to the lower end of the inner cavity of the feed housing 6.

[0039] Specifically: The drive motor 8 adopts an existing motor on the market, which is a current technology. The drive motor 8 drives the spiral feed rod 7 to rotate, thereby enabling the feeding of materials quickly and avoiding the blockage of carbon powder during feeding.

[0040] like Figure 3 As shown, the limiting ring 4 has a first limiting cavity 13 at the insertion point of the pressure rod 12. A first retaining ring is fixedly sleeved inside the first limiting cavity 13 on the outer side of the pressure rod 12, and a first spring 14 is sleeved on the lower part of the first retaining ring on the outer side of the pressure rod 12. The arc center of the pressure rod 12 coincides with the center of the connecting shaft 15.

[0041] The limiting ring 4 has a second limiting cavity 16 at the insertion point of the push rod 18. The upper end of the push rod 18 is fixedly connected to a second retaining ring, and the upper end of the push rod 18 is provided with a second spring 17 inside the second limiting cavity 16. The arc center of the push rod 18 coincides with the center of the connecting shaft 15.

[0042] Specifically: the lower end of the sealing plug 3 will press the pressure rod 12, which will cause the lower end of the pressure rod 12 to press the moisture-proof baffle 9, thereby causing the moisture-proof baffle 9 to rotate to the left. This will cause the left end of the moisture-proof baffle 9 to press the right end of the sealing feed housing 6, thereby increasing the sealing performance at the feed port 2 of the equipment and achieving a highly efficient moisture-proof effect. After the pressure rod 12 pushes the moisture-proof baffle 9, the moisture-proof baffle 9 will push the pressure push rod 18, which will compress the second spring 17.

[0043] like Figure 2 and Figure 4 As shown, a sealing strip is provided on the outer side of the left end of the moisture-proof baffle 9, and the shape of the sealing strip is the same as that of the right end of the feed housing 6.

[0044] Specifically: the moisture-proof baffle 9 can seal the right end of the feed housing 6.

[0045] like Figure 2 As shown, multiple sealing rings 5 ​​are equidistantly embedded on the lower outer side of the sealing plug 3.

[0046] In other words, the sealing ring 5 can increase the sealing performance of the sealing plug 3.

[0047] Working principle: When the sealing plug 3 is inserted and sealed inside the feeding port 2, the lower end of the sealing plug 3 will squeeze the pressure rod 12, which will cause the lower end of the pressure rod 12 to squeeze the moisture-proof baffle 9, thereby causing the moisture-proof baffle 9 to rotate to the left. This causes the left end of the moisture-proof baffle 9 to squeeze the right end of the sealing feed housing 6, thereby increasing the sealing performance at the feeding port 2 of the equipment and having a highly efficient moisture-proof effect. After the pressure rod 12 pushes the moisture-proof baffle 9, the moisture-proof baffle 9 will push the pressure push rod 18 and compress the second spring 17.

[0048] When feeding is required, the sealing plug 3 is manually unscrewed, so that the upper end of the pressure rod 12 is not squeezed. Under the elastic force of the second spring 17, the moisture-proof baffle 9 will rotate to the right, so that the moisture-proof baffle 9 will not seal the right end of the feeding housing 6. The drive motor 8 is started to drive the spiral feeding rod 7 to rotate, and the added material enters the inner side of the toner box body 1 at an accelerated speed, so that the feeding will not cause the phenomenon of material blockage.

[0049] The above description is merely a specific embodiment of this application, enabling those skilled in the art to understand or implement this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features claimed in this application.
