Description

Technical Field

[0001] The utility model relates to the technical field of toner cartridges in laser printers, in particular to a toner cartridge which is convenient for observing waste toner. Background Art

[0002] In laser printers, more than 70% of the imaging components are concentrated in the toner cartridge. The quality of printing is actually largely determined by the toner cartridge. The toner in the toner cartridge is the key to imaging during the printing process. As the printing equipment is used, the waste toner in the waste toner collection bin will gradually increase. If it is not cleaned for a long time or is not cleaned in time, the waste toner will accumulate too much, leading to a variety of problems. First, the waste toner may leak out of the toner cartridge, contaminating the inside of the printer and the printed paper, causing a decline in print quality, such as irregular black spots, black blocks or bottom ash on the paper. Secondly, the dirty objects such as paper ash and fiber in the waste toner will rub against the toner cartridge for a long time, which will wear the photosensitive film on the surface of the toner cartridge, thereby affecting the life of the toner cartridge and the printing effect. In addition, the harmful substances in the waste toner may also pose a potential threat to the environment and human health. In order to clean up the waste toner in time, it is necessary to observe the accumulation of waste toner well.

[0003] For example, a Chinese utility model patent with publication number CN214252897U discloses a toner cartridge that is easily sealed, including a second shell and a first shell, the first shell is arranged at the left end of the second shell, the second shell is fixed with the first shell by clamping, a waste bin is arranged at the left end of the first shell, a cleaning scraper is arranged on the left side of the interior of the first shell, a photosensitive drum is arranged on the right side of the cleaning scraper, a powder scraper is arranged on the left side of the interior of the second shell, the waste bin is composed of a detection sensor, a first observation window, a shell and a second observation window, the second observation window is arranged on the inner side of the upper end of the shell, the first observation window is arranged on the inner side of the left end of the shell, a detection sensor is arranged at the lower end of the first observation window, and the waste bin is fixedly connected to the first shell through the shell.

[0025] Please refer to Figure 1-4, A toner cartridge facilitating the observation of waste toner, comprising a first housing 1 and a second housing 2. A photosensitive drum 3 is provided between the first housing 1 and the second housing 2. A powder inlet chamber 4 is provided inside the first housing 1, and a waste toner chamber 5 is provided inside the second housing 2. A first observation window 6 is provided on one side of the second housing 2. The first observation window 6 is rotatably connected to the second housing 2. A second observation window 8 is provided below the first observation window 6. The second observation window 8 is slidably connected to the second housing 2 through a first sliding guide rail 9. A detection sensor 10 adjacent to the first observation window 6 is installed inside the second housing 2.

[0026] Specifically, the waste toner generated when the photosensitive drum 3 works enters the waste toner chamber 5 and gradually accumulates as the work continues. The detection sensor 10 can be arranged on the inner side wall of the waste toner chamber 5, and can detect the accumulated waste toner in the waste toner chamber 5 to obtain relevant information. The detection sensor 10 can be a weight detection sensor 10 and / or a visual detection sensor 10. By detecting the weight of the waste toner in the waste toner chamber 5 and / or the accumulation amount of the waste toner in the waste toner chamber 5, the accumulation situation of the waste toner can be accurately obtained. Among them, both the first housing 1 and the second housing 2 have front and rear side walls (not shown), and both the first housing 1 and the second housing 2 are structures with a hollow interior wrapped by an outer shell.

[0027] Among them, both the first observation window 6 and the second observation window 8 are rectangular plate-shaped transparent structures, and are preferably made of transparent plastic material, so as to be convenient for observation while effectively ensuring that the first observation window 6 and the second observation window 8 are not easily damaged during frequent opening and closing.

[0028] The toner cartridge provided by the present utility model is provided with a first observation window 6 at the upper end of the side of the waste toner chamber 5 and a second observation window 8 on the side of the waste toner chamber 5. By setting the first observation window 6 to be rotatably connected to the second housing 2 and setting the second observation window 8 to be slidably connected to the second housing 2 through the first sliding guide rail 9, it is convenient to rotate and open the first observation window 6 or horizontally pull open the second observation window 8 to observe the waste toner when the first observation window 6 and the second observation window 8 are contaminated by the waste toner, and at the same time, it is convenient to clean the first observation window 6 and the second observation window 8 to ensure the effect of observing the waste toner through the first observation window 6 and the second observation window 8. In addition, when the detection sensor 10 is damaged, since the detection sensor 10 is arranged adjacent to the first observation window 6, the detection sensor 10 can be easily taken out for repair by opening the first observation window 6, so it is also convenient for the disassembly and repair of the detection sensor 10.

[0029] In an optional embodiment, the second housing 2 is provided with an inclined side wall 19, the inclined side wall 19 faces the bottom of the waste toner chamber 5, and the first observation window 6 is arranged at the inclined side wall 19.

[0030] Specifically, by arranging the first observation window 6 on the inclined side wall directly opposite the bottom of the waste powder bin 5, compared with the prior art solution where the observation window is arranged directly above, it can obtain a better observation field of view without being blocked by the inclined side wall, thus making it more convenient to observe the waste powder.

[0031] In an alternative embodiment, the lower end of the second outer shell 2 is provided with a second sliding guide rail 11 and a sliding cover 13. The sliding cover 13 is slidably connected to the second outer shell 2 through the second sliding guide rail 11, and a push-pull handle 12 is connected to the side end of the sliding cover 13.

[0032] Specifically, by arranging the second sliding guide rail 11 and the sliding cover 13 at the lower end of the second outer shell 2, the sliding cover 13 is slidably connected to the second outer shell 2 through the second sliding guide rail 11, and a push-pull handle 12 is connected and arranged at the side end of the sliding cover 13. Therefore, when there is a large accumulation of waste powder in the waste powder bin 5, the sliding cover 13 can be easily pulled open through the push-pull handle 12 to quickly discharge and remove a large amount of waste powder.

[0033] In an alternative embodiment, a lifting handle 14 is connected to the upper end of the first observation window 6. There are two second observation windows 8, and a horizontal pull handle 15 is connected to both of the two second observation windows 8.

[0034] Specifically, by arranging the lifting handle 14, it is convenient to open and close the first observation window 6 by lifting to observe the waste powder in the waste powder bin, and at the same time, it is convenient to clean the inner wall of the first observation window 6 and take out the detection sensor 10; by arranging two second observation windows 8 and connecting and arranging a horizontal pull handle 15 on both of the two second observation windows 8, the second observation window can be opened from either side, thus making it more convenient to open and close the second observation window to observe the waste powder in the waste powder bin, and at the same time, it is convenient to clean the inner wall of the second observation window 6.

[0035] In an alternative embodiment, an alarm 16 is provided at the upper end of the second outer shell 2, and the alarm 16 is electrically connected to the detection sensor 10.

[0036] Specifically, by arranging the alarm 16 at the upper end of the second outer shell 2 and electrically connecting the alarm 16 to the detection sensor 10, the alarm 16 can issue an alarm when the waste powder in the waste powder bin 5 accumulates to a certain threshold. Therefore, through the alarm 16, it is convenient to monitor the accumulation situation of the waste powder inside the waste powder bin 5 in real time.

[0037] In an alternative embodiment, one end of the first observation window 6 is rotatably connected to the second outer shell 2 through a hinge 7.

[0038] Specifically, by setting the hinge 7 to achieve the rotational connection between the first observation window 6 and the second housing 2, it is convenient to repair or replace when the hinge 7 is damaged, which is beneficial to ensuring that the first observation window 6 can be smoothly opened and closed.

[0039] In an optional embodiment, the second observation window 8 is provided with scale marks 20.

[0040] Specifically, the scale marks 20 are provided on one side end face of the second observation window 8 for the observer to read the accurate accumulation amount of waste powder in the waste powder bin through the scale marks 20, which is beneficial for the observer to accurately grasp the information of the waste powder accumulation amount, thus ensuring accurate observation.

[0041] Working principle: When the laser printer is working, the charging roller 18 charges the photosensitive drum 3. The laser printer emits the light beam generated by the laser emitter thereof onto the photosensitive drum 3 to form a latent image on the surface of the selenium drum. The developing roller 17 drives the powder in the powder supply bin 4 to rotate under the action of the photosensitive drum 3, and the powder is adsorbed onto the selenium drum, so that the latent image is converted into a real image. With the feeding of the printing paper, the powder on the surface of the selenium drum is transferred onto the printing paper by a transfer roller (not shown) provided below the photosensitive drum 3 to form an image. Then, by using the method of pressure melting, the image is fixed on the printing paper to complete the printing process. After that, the residual powder on the surface of the photosensitive drum 3 is scraped into the waste powder bin 5, and the waste powder gradually accumulates as the laser printer continuously works. Through the first observation window 6 and the second observation window 8, a good observation view of the waste powder in the waste powder bin 5 can be obtained, and the waste powder amount in the waste powder bin 5 can be detected in real time through the detection sensor 10. When the detection sensor 10 is damaged and the first observation window 6 and the second observation window 8 are contaminated by waste powder, seriously hindering the observer from observing and grasping the waste powder accumulation situation, the observer can open the first observation window 6 or the second observation window 8 to directly observe the waste powder accumulation situation, and at the same time, the inner side wall of the first observation window 6 or the second observation window 8 can be cleaned, or the detection sensor 10 can be taken out through the first observation window 6 for repair, so as to facilitate the observation of waste powder while ensuring the observation effect of waste powder.

[0042] The above content is a further detailed description of the present utility model in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several simple deductions or replacements can still be made, which should all be regarded as belonging to the protection scope of the present utility model.
