Technical Field

[0001] The utility model relates to the technical field of toner, in particular to a toner cartridge convenient for observing the toner capacity. Background Art

[0002] When a laser printer is printing, it needs a toner cartridge installed in a developing device to provide toner. After the powder filling cover is removed from the machine, it is driven by a buckle structure in the developing device to open, and the powder filling port is exposed to provide toner to the printer. According to user feedback, after using it for a period of time, the printer prints unclearly. To determine whether there is toner in the toner cartridge, the toner cartridge needs to be taken out and shaken to judge whether there is still toner. If the toner cartridge is out of toner, since the original designed powder filling cover cannot be manually pushed open, no additional toner can be added, and it can only be discarded, resulting in waste of resources.

One side of the first chain 7 is provided with a connecting frame 2. A first slider 4 is slidably connected to the inner wall of the connecting frame 2. One side of the first slider 4 is rotationally connected to one side of the first chain 7. The side of the connecting frame 2 away from the first chain 7 is slidably connected to one side of the inner wall of the second box body 12. A strip-shaped opening 11 is opened at the top of the inner wall of the first box body 1 close to the second box body 12. A connecting rod 15 is fixedly connected to the position of the connecting frame 2 close to the strip-shaped opening 11.

[0025] As an alternative technical solution of the present utility model, a third box body 10 is fixedly connected to one side of the outer wall of the first box body 1. A rotating motor 13 is fixedly connected to the inner wall of the third box body 10. A second chain 9 is provided between the output end of the rotating motor 13 and one of the two sprockets 6. By using this solution, the rotating motor 13 can be used to drive the second chain 9 to rotate. The rotation of the second chain 9 can drive the two sprockets 6 and the first chain 7 to rotate, driving the connecting frame 2 to move repeatedly.

[0026] As an alternative technical solution of the present utility model, a distance measuring instrument 3 is fixedly connected to the position near the center of the top surface of the outer wall of the first box body 1. The output end of the distance measuring instrument 3 passes through the top of the first box body 1, and the output end of the distance measuring instrument 3 faces directly downward. By using this solution, the distance measuring instrument 3 can be used to measure the distance between the feed inlet 16 and the bottom surface of the inner wall of the first box body 1 at all times. When the first box body 1 is filled with toner, the thickness of the toner can be measured, and the remaining amount of toner can be observed according to the thickness of the toner.

[0027] As an alternative technical solution of the present utility model, a display 5 is fixedly connected to the top surface of the outer wall of the first box body 1. The signal output end of the distance measuring instrument 3 is electrically connected to the signal input end of the display 5. By using this solution, the data measured by the distance measuring instrument 3 can be transmitted to the surface of the display 5 at all times, which can reduce the difficulty of personnel operation and further facilitate the personnel to observe the remaining amount of toner.

[0028] As an alternative technical solution of the present utility model, a second slider 8 is fixedly connected to the side of the connecting frame 2 away from the first chain 7. A strip-shaped chute 14 is provided at the position of the inner wall of the second box body 12 near the second slider 8. The second slider 8 is slidably connected to the strip-shaped chute 14. By using this solution, the connecting frame 2 can be limited, preventing the connecting frame 2 from shaking or rotating randomly, so that the connecting frame 2 moves back and forth in a straight line inside the second box body 12, which can drive the connecting rod 15 to move back and forth.

[0029] As an alternative technical solution of the present utility model, the connecting rod 15 is Z-shaped. One end of the connecting rod 15 passes through the strip-shaped opening 11, and one end of the connecting rod 15 is in contact with the bottom surface of the inner wall of the first box body 1. By using this solution, during the repeated movement of the connecting rod 15, the toner inside the first box body 1 can be leveled, so that the toner inside the first box body 1 is always in a flat state, increasing the accuracy of the measurement by the distance measuring instrument 3.

[0030] The following steps are required when using this toner cartridge that is convenient for observing the toner capacity:

[0031] 1) The distance measuring instrument 3 detects the distance from the feed inlet 16 to the inner bottom surface of the box body 1. After injecting toner, the distance from the feed inlet 16 to the top surface of the toner can be detected, and thus the thickness of the toner can be judged.

[0032] 2) The connecting frame 2 is slidably connected to the second box body 12, which has the effect of limiting the connecting frame 2, and the connecting frame 2 can move linearly inside the second box body 12;

[0033] 3) The connecting rod 15 moves repeatedly inside the first box body 1 to level the toner, so that the toner is in a flat state.

[0034] In summary, when the user uses it, the distance measuring instrument 3 detects the distance from the feed port 16 to the bottom surface inside the box body 1. After injecting the toner, it can detect the distance from the feed port 16 to the top surface of the toner. Thus, the thickness of the toner can be judged, and the data is sent to the display 5 at the same time, which is convenient for the staff to observe and requires no excessive operation. Finally, the connecting frame 2 is slidably connected to the second box body 12, which has the effect of limiting the connecting frame 2. The connecting frame 2 can move linearly inside the second box body 12. The rotating motor 13 drives the first chain 7 to rotate. The first slider 4 is rotatably connected to the first chain 7 and slidably connected to the connecting frame 2. When the first chain 7 drives the connecting frame 2 to move, the connecting frame 2 can be kept vertical at all times. At the same time, the connecting rod 15 moves repeatedly inside the first box body 1 to level the toner, so that the toner is in a flat state. This can not only increase the uniformity of toner output to ensure the printing quality, but also increase the accuracy of the distance measuring instrument 3.
