Abstract
Description
Technical Field
[0001] This utility model relates to the field of toner cartridge refilling technology, specifically to a toner cartridge refilling device. Background Technology
[0002] A toner cartridge refilling device is a tool used to replenish toner cartridges. Its reasonable structural design prevents toner leakage, and it is convenient and efficient to operate, reducing operating costs and extending the life of the toner cartridge.
[0003] Traditional toner cartridges require operators to repeatedly squeeze the toner bottle against the toner compartment during refilling. However, the connection between the toner bottle and the compartment is unstable during this process. If the connection becomes loose, gaps can form, allowing toner to leak out. This leaked toner can then disperse into the air, posing a potential health hazard to the respiratory system if inhaled. Therefore, a new toner cartridge refilling device is proposed. Utility Model Content

[0022] like Figure 1-3 As shown, a toner cartridge refilling device includes a toner cartridge 1, an internal toner hopper 2 for loading toner, and an internal input end of the toner hopper 2 for auxiliary sealing or toner refilling, such as... Figure 1-3 As shown, specifically, the connecting component 3 includes an internal threaded sleeve 301. The internal input end of the powder hopper 2 is provided with an internal threaded sleeve 301. Two symmetrically distributed mounting blocks 302 are fixedly installed on the outer wall of the internal threaded sleeve 301. Each mounting block 302 is fixedly connected to the inner wall of the powder hopper 2.
[0023] More specifically, since the internal threaded sleeve 301 is located at the internal input end of the powder hopper 2, the internal threaded sleeve 301 provides a connection base, which not only provides a reliable point of force and support for the subsequent sealing operation of the powder hopper 2, but also creates the necessary connection conditions for operations such as accurately adding carbon powder into the powder hopper 2.
[0024] The input end of the powder hopper 2 is provided with a powder hopper cover assembly 4 for sealing the inlet of the powder hopper 2, such as... Figure 1-2 As shown, specifically, the powder hopper cover assembly 4 includes a lead screw 401. The input end of the powder hopper 2 is provided with the lead screw 401, and the left end of the lead screw 401 is fixedly installed with the powder hopper cover 402. The lead screw 401 is threadedly connected to the inside of the internal thread sleeve 301.
[0025] More specifically, when it is necessary to perform a sealing operation on the input end of the powder hopper 2, the operator can hold the powder hopper cover 402 and rotate it. During the rotation, the lead screw 401 will be tightly connected to the inside of the internal thread sleeve 301 through the thread structure. After the connection is in place, the powder hopper cover 402 can effectively seal the input end of the powder hopper 2, thereby achieving the sealing purpose.
[0026] The drum 1 is provided with a flow guiding component 5 on its side for guiding and adding toner, such as... Figure 1 , 3 As shown, specifically, the flow guiding assembly 5 includes a flow guiding cover 501. The flow guiding cover 501 is disposed on the side of the drum 1. The output end of the flow guiding cover 501 is fixedly connected to a connecting pipe 502. The output end of the connecting pipe 502 is fixedly connected to an external threaded pipe 503. The input end of the flow guiding cover 501 is fixedly connected to an internal threaded ring 504. A threaded cap 505 is threadedly connected to the external threaded pipe 503. A rubber sleeve 506 is fixedly installed on the outer wall of the flow guiding cover 501. A threaded cap 507 is threadedly connected to the inner thread of the internal threaded ring 504.
[0027] More specifically, when injecting toner into the toner hopper 2, the lead screw 401 is first rotated to separate from the internal threaded sleeve 301, and then the external threaded tube 503 is rotated to connect to the inside of the internal threaded sleeve 301. After the toner enters the inside of the flow guide 501, the toner inside the flow guide 501 will continue to enter the inside of the toner hopper 2 through the connecting tube 502 and the external threaded tube 503. Since the external threaded tube 503 and the internal threaded sleeve 301 are in a threaded connection and will not easily loosen, the leakage of toner is effectively avoided. The rubber sleeve 506 contacting the input end of the toner hopper 2 can also help to achieve a sealing effect. The threaded cap 1 505 and threaded cap 2 507 can effectively seal the internal space of the flow guide 501, the connecting tube 502, and the external threaded tube 503 when no toner is added.
[0028] The toner cartridge 1 is provided with a toner bottle assembly 6 for adding toner on its side, such as... Figure 1 , 3 As shown, specifically, the toner bottle assembly 6 includes a toner bottle 601, which is disposed on the side of the drum 1, and an external threaded ring 602 is fixedly installed at the output end of the toner bottle 601.
[0029] More specifically, when injecting toner into the toner hopper 2, firstly, the lead screw 401 is rotated to separate from the inner threaded sleeve 301, then the outer threaded tube 503 is rotated to connect to the inside of the inner threaded sleeve 301, and then the outer threaded ring 602 is threaded to the inside of the inner threaded ring 504, so that the outer threaded ring 602 and the outer threaded tube 503 are in a threaded connection state and will not easily loosen. Then, the toner bottle 601 can be squeezed to allow the toner inside to enter the guide shroud 501.
[0030] In summary: When the connecting component 3 and the toner cartridge cover component 4 are threadedly connected, the toner cartridge cover component 4 can seal and block the input end of the toner cartridge 2, thereby preventing toner leakage from the toner cartridge 2. When injecting toner into the toner cartridge 2, firstly, the toner cartridge cover component 4 and the connecting component 3 are rotated and separated, then the flow guide component 5 and the toner bottle component 6 are threadedly connected, and then the connecting component 3 and the flow guide component 5 are threadedly connected. Finally, the drum unit 1 is placed vertically with the input end of the toner cartridge 2 facing upwards. At this time, the toner inside the toner bottle component 6 can enter the toner cartridge 2 through the flow guide component 5. Since the connecting component 3 and the flow guide component 5, and the flow guide component 5 and the toner bottle component 6 are all threadedly connected, even if the toner bottle component 6 is repeatedly squeezed to allow toner to enter the toner cartridge 2, the toner bottle component 6, the flow guide component 5, and the connecting component 3 will not easily loosen, effectively preventing toner leakage.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
