Description

Technical Field

[0001] The utility model relates to the technical field of selenium cartridges, in particular to an environmentally friendly selenium cartridge. Background Art

[0002] Toner cartridges, also known as photosensitive drums, are generally composed of a basic substrate made of aluminum and a photosensitive material coated on the substrate. Toner cartridges not only determine the quality of printing, but also determine how much money users need to spend during use. In laser printers, more than 70% of the imaging components are concentrated in the toner cartridge, and the quality of printing is actually largely determined by the toner cartridge. In the prior art, the powder bins in toner cartridges are sealed with sponge strips. During production and assembly, it is easy to cause poor sealing of the powder bin, causing carbon powder to leak from the gap, thus making the product unqualified, resulting in high product costs and low production efficiency. On the other hand, the general toner cartridge page output is 1,500 pages, and it cannot be used again after use, causing waste and environmental protection, and it is inconvenient to add powder twice, which increases the cost of use for consumers.

[0003] To solve the above problems, the existing patent (Announcement No.: CN217007966U) is an environmentally friendly toner cartridge, which effectively solves the defects of simple functions and crude structures of most traditional toner cartridges on the market by setting up gravity sensors, spring frames and other components. While ensuring the basic printing effect, it can also ensure the protection of the toner cartridge and the absorption effect of excess powder when adding powder, further improving the practicality of the entire device.

[0004] However, during the use of the toner cartridge in the above-mentioned public document, when the toner inside the toner cartridge is almost consumed, toner is directly added inside. At this time, the new toner will be mixed with the residual toner, affecting the printing effect of the printer. At the same time, there is always residual toner on the inner wall of the powder bin, which will also cause a certain degree of waste.

[0005] Therefore, those skilled in the art provide an environmentally friendly toner cartridge to solve the problems raised in the above background technology. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides an environmentally friendly toner cartridge. By setting a gravity sensor, the amount of toner inside the powder bin can be monitored in real time by weight. When the amount of toner is small, the gravity sensor controls the movement of the cleaning mechanism through the control system. By setting the cleaning mechanism, the inner wall of the powder bin can be automatically cleaned, which can effectively avoid the mixing of residual toner and new toner, thereby ensuring that the printer has a good printing effect. Secondly, by setting a buzzer, a sound can be emitted to directly remind the staff to add toner, which is very convenient, so as to solve the problems raised in the above-mentioned background technology.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] An environmentally friendly toner cartridge comprises a toner cartridge body, a connecting strip being fixedly connected to the rear end of the toner cartridge body, a powder bin being arranged inside the connecting strip, a gravity sensing component being arranged on the inner wall of the powder bin, a cleaning mechanism being arranged inside the powder bin, the cleaning mechanism comprising a partition fixedly connected to the inside of the powder bin, a small motor being connected to one side of the partition, a reciprocating screw being connected to the output shaft of the small motor, a connecting block being connected to the reciprocating screw via a threaded sleeve transmission, and the connecting block being connected to a wiping ring via a connecting rod.

[0009] As a further solution of the present invention, the gravity sensor is electrically connected to a small motor.

[0010] As a further solution of the utility model, a slide groove is opened inside the powder bin, a second conductive block is arranged inside the slide groove, a first conductive block is fixedly connected to the outer wall of the wiping ring, and the first conductive block is located inside the slide groove.

[0011] As a further solution of the utility model, a buzzer is provided on the connecting strip, the second conductive block is electrically connected to the buzzer, and the first conductive block is electrically connected to an external power supply.

[0012] As a further solution of the utility model, a notch is opened on the outer wall of the powder bin, and a filter is arranged on the notch.

[0013] As a further solution of the utility model, a feed port is arranged on the connecting strip, the feed port is communicated with the powder bin, and a photosensitive drum is arranged at the lower end of the toner cartridge body.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] By setting up a gravity sensor, the amount of toner inside the powder bin can be monitored in real time by weight. When the amount of toner is small, the gravity sensor controls the movement of the cleaning mechanism through the control system. By setting up the cleaning mechanism, the inner wall of the powder bin can be automatically cleaned, which can effectively prevent residual toner from mixing with new toner, ensuring that the printer has a good printing effect. Secondly, by setting up a buzzer, a sound can be emitted to directly remind the staff to add toner, which is very convenient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] See also Figures 1 to 3 In the embodiment of the utility model, an environmentally friendly toner cartridge includes a toner cartridge body 1, a connecting strip 2 is fixedly connected to the rear end of the toner cartridge body 1, a powder bin 3 is arranged inside the connecting strip 2, the powder bin 3 is used to place toner powder, a feed port 4 is arranged at the upper end of the powder bin 3, toner powder can be added to the powder bin 3 through the feed port 4, a photosensitive drum 5 is arranged at the lower end of the toner cartridge body 1, a notch 6 is opened on the powder bin 3, toner powder can flow out through the notch 6 for work, a filter screen 7 is arranged on the notch 6, the filter screen 7 can separate the toner powder, and it is convenient for printing operation.

[0021] A gravity sensor 14 is provided at the inner wall of the lower end of the powder bin 3 , and the remaining amount of carbon powder inside the powder bin 3 can be directly known by monitoring the state of the gravity sensor 14 .

[0022] A partition 8 is provided inside the powder bin 3, and a small motor 9 is provided at one end of the partition 8. When the gravity sensor 14 detects that the amount of carbon powder inside the powder bin 3 is small, the small motor 9 will be controlled by the control system to start working. The output shaft of the small motor 9 passes through the partition 8 and is connected to a reciprocating screw 10. When the small motor 9 is working, it will drive the reciprocating screw 10 to rotate synchronously. The reciprocating screw 10 is connected to a connecting block 11 through a threaded sleeve transmission. Under the action of the reciprocating screw 10, the connecting block 11 makes horizontal reciprocating motion. A wiping ring 13 is connected to the connecting block 11 through a connecting rod 12. The wiping ring 13 contacts the inner wall of the powder bin 3. When the wiping ring 13 moves with the connecting block 11, the inner wall of the powder bin 3 is cleaned.

[0023] A slide groove 15 is provided on the inner wall of the powder bin 3, and a second conductive block 17 is arranged inside the slide groove 15. A first conductive block 16 is fixedly connected to the wiping ring 13. When the wiping ring 13 moves, the first conductive block 16 moves along the slide groove 15. A buzzer 18 is provided on the connecting strip 2. When the first conductive block 16 moves to contact with the second conductive block 17, the buzzer 18 is powered, reminding the staff to add carbon powder in time.

[0024] The working principle of the utility model is as follows: when adding new carbon powder to the powder bin 3, it is necessary to clean the inside of the powder bin 3 first. When the carbon powder inside the powder bin 3 is less, the gravity sensor 14 transmits the signal to the control system after monitoring. The control system starts the small motor 9 to work. When the small motor 9 works, it will drive the reciprocating screw 10 to rotate synchronously. Under the limitation of the first conductive block 16 and the slide groove 15, the wiping ring 13 is driven by the connecting block 11 and the connecting rod 12 to move and clean along the inner wall of the powder bin 3 to avoid the residual carbon powder from mixing with the subsequently added carbon powder and affecting the printing effect of the printer. When the first conductive block 16 moves, it will gradually approach the second conductive block 17. When the first conductive block 16 moves to contact with the second conductive block 17, the work of the buzzer 18 is completed. The buzzer 18 makes a sound to remind relevant personnel to replenish the carbon powder in time.
