Description

Technical Field

[0001] This utility model relates to the field of toner cartridge technology, specifically to a toner cartridge with a toner cartridge detection function. Background Technology

[0002] A toner cartridge, also known as a photosensitive drum, is generally composed of a base material made of aluminum and a photosensitive material coated on the base material. In laser printers, more than 70% of the imaging components are concentrated in the toner cartridge, and the print quality is actually largely determined by the toner cartridge.

[0003] The drum unit has a refill port at one end for adding toner. This port is usually only covered by a cover, which is not very airtight and can easily lead to toner leakage. Utility Model Content

[0004] The purpose of this invention is to provide a toner cartridge with a toner outlet detection function to solve the problem of toner leakage that easily occurs during the use of toner cartridges, as mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a toner cartridge with a toner nozzle detection device, comprising a toner cartridge body, the toner cartridge body being composed of a support, a developing roller, a toner hopper, and a toner filling port, the developing roller being mounted on the surface of the support, the toner hopper being mounted on the surface of the support, a toner filling port being provided on one side of the toner hopper, the toner filling port being connected to the toner hopper, the toner filling port being opened on the surface of the support, and a toner nozzle detection mechanism being provided on the outside of the toner filling port, the toner nozzle detection mechanism including a detection component and a sealing component inside.

[0006] Preferably, a sealing component is inserted into the surface of the powder filling port, and a detection component is provided on the outside of the sealing component.

[0007] Preferably, the detection component consists of a powder discharge hole, a sealing plug, an observation window, and a collection cover. One end of the bracket is fixed with a collection cover, which is fitted onto the outside of the powder filling port. Observation windows are embedded on both sides of the surface of the collection cover.

[0008] Preferably, a powder discharge hole is provided at the bottom of the collection cover, and the inside of the powder discharge hole is filled with a sealing plug.

[0009] Preferably, the sealing component includes a threaded sealing cap, a threaded groove, and a sealing gasket. The threaded sealing cap is inserted into the powder filling port, and one end of the threaded sealing cap passes through the collection cap and extends to the outside of the collection cap.

[0010] Preferably, a sealing gasket is fitted onto the surface of the threaded sealing cap, and the surfaces at both ends of the sealing gasket are in close contact with the surfaces of the threaded sealing cap and the powder filling port, respectively.

[0011] Preferably, the powder filling port has a threaded groove inside, and the threaded groove and the threaded sealing cap are threadedly engaged.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The toner cartridge with toner outlet detection is equipped with a toner outlet detection mechanism. During use, toner can be filled into the toner hopper through the toner filling port. After filling, the sealing gasket can be put onto the surface of the threaded sealing cover. Then, the threaded sealing cover is inserted into the toner filling port and rotated. With the threaded engagement between the threaded sealing cover and the threaded groove, the threaded sealing cover is fixed inside the toner filling port, sealing the toner filling port. At this time, the sealing gasket is in close contact with the surface of the toner filling port, sealing the toner filling port and preventing toner leakage.

[0013] If the sealing gasket ages and thins over time, resulting in poor sealing performance and toner leakage, the leaked toner will fall into the collection cover and can be observed through the observation window. At this time, the threaded sealing cap can be rotated to remove it, and the sealing gasket can be removed and replaced. At the same time, the sealing plug can be removed to discharge and collect the toner inside the collection cover. This realizes the toner leakage detection function of the toner cartridge to the toner filling port, making it less likely for toner cartridges to leak during use. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0020] This utility model provides a toner cartridge with a toner nozzle detection structure as follows: Figure 1 and Figure 2 As shown, the device includes a drum body 1, which consists of a support 11, a developing roller 12, a toner hopper 13, and a toner filling port 14. The developing roller 12 is mounted on the surface of the support 11, and the toner hopper 13 is mounted on the surface of the support 11.

[0021] Furthermore, such as Figure 4 As shown, a powder filling port 14 is provided on one side of the powder hopper 13. The powder filling port 14 is connected to the powder hopper 13. The powder filling port 14 is opened on the surface of the support 11. A powder filling port detection mechanism 2 is provided on the outside of the powder filling port 14. The powder filling port detection mechanism 2 includes a detection component 21 and a sealing component 22 inside. The sealing component 22 is inserted into the surface of the powder filling port 14. The detection component 21 is provided on the outside of the sealing component 22. The detection component 21 consists of a powder discharge hole 211, a sealing plug 212, an observation window 213, and a collection cover 214. A collection cover 214 is fixed at one end of the support 11. The collection cover 214 is sleeved on the outside of the powder filling port 14. Observation windows 213 are embedded on both sides of the surface of the collection cover 214. A powder discharge hole 211 is opened at the bottom of the collection cover 214. The powder discharge hole 211 is filled with a sealing plug 212.

[0022] Furthermore, such as Figure 4 As shown, the sealing component 22 includes a threaded sealing cap 221, a threaded groove 222, and a sealing gasket 223. The threaded sealing cap 221 is inserted into the powder filling port 14. One end of the threaded sealing cap 221 passes through the collection cap 214 and extends to the outside of the collection cap 214. The sealing gasket 223 is fitted on the surface of the threaded sealing cap 221. The surfaces of both ends of the sealing gasket 223 are in close contact with the surfaces of the threaded sealing cap 221 and the powder filling port 14, respectively. The powder filling port 14 has a threaded groove 222 inside, and the threaded groove 222 is threadedly engaged with the threaded sealing cap 221.

[0023] In use, powder is poured into the powder hopper 13 through the powder filling port 14. After the powder is poured, the sealing gasket 223 can be put onto the surface of the threaded sealing cover 221. Then, the threaded sealing cover 221 is inserted into the powder filling port 14 and rotated. With the threaded engagement between the threaded sealing cover 221 and the threaded groove 222, the threaded sealing cover 221 is fixed inside the powder filling port 14, sealing the powder filling port 14. At this time, the sealing gasket 223 is in close contact with the surface of the powder filling port 14, sealing the powder filling port 14 and preventing powder leakage.

[0024] If the sealing gasket 223 ages and thins over a long period of time, resulting in poor sealing performance and toner leakage, the leaked toner will fall into the collection cover 214 and can be observed directly through the observation window 213. At this time, the threaded sealing cover 221 can be rotated to remove it, and the sealing gasket 223 can be removed and replaced. At the same time, the sealing plug 212 can be removed to discharge and collect the toner inside the collection cover 214, so as to realize the toner leakage detection function of the drum to the toner filling port 14.

[0025] Working principle: When in use, powder is first poured into the powder hopper 13 through the powder filling port 14. After the powder is poured, the sealing gasket 223 is put onto the surface of the threaded sealing cover 221. Then, the threaded sealing cover 221 is inserted into the powder filling port 14 and rotated. With the threaded engagement between the threaded sealing cover 221 and the threaded groove 222, the threaded sealing cover 221 is fixed inside the powder filling port 14, sealing the powder filling port 14. At this time, the sealing gasket 223 is in close contact with the surface of the powder filling port 14, sealing the powder filling port 14 and preventing powder leakage.

[0026] If the sealing gasket 223 ages and thins over a long period of time, resulting in poor sealing performance and toner leakage, the leaked toner will fall into the collection cover 214 and can be observed directly through the observation window 213. At this time, the threaded sealing cover 221 can be rotated to remove it, and the sealing gasket 223 can be removed and replaced. At the same time, the sealing plug 212 can be removed to discharge and collect the toner inside the collection cover 214, so as to realize the toner leakage detection function of the drum to the toner filling port 14, making it less likely for toner leakage to occur during use, and finally completing the use of the drum.
