Description

Technical Field

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

[0002] Many toner cartridges allow users to refill the original toner cartridges themselves after they run out, so individual toner cartridges are also available on the market. Refilling toner yourself significantly reduces the cost of consumables for users. Toner, also called carbon powder, is a powdery substance used in laser printers to create and fix images on paper. Black toner is composed of binder resin, carbon black, charge control agents, and additives.

[0003] Traditional toner refills are typically stored in toner cartridges, where the powder is squeezed out from the funnel head. However, each time toner is squeezed out, excess toner is easily squeezed out with the air and sprayed out from the toner filling port of the drum, causing dust. This is still somewhat inconvenient in actual use. Therefore, there is an urgent need for a toner cartridge to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a toner cartridge to solve the problem mentioned in the background art that traditional toner refills are generally stored in a toner cartridge and the powder is squeezed out from the funnel head by squeezing the cartridge body. However, each time the toner is squeezed out, the toner is easily squeezed out in excess with the air and sprayed out from the toner filling port of the drum, causing dust. This still has certain inconveniences in actual use.

[0005] This utility model provides the following technical solution: a toner box, including a toner replenishing mechanism, wherein the toner replenishing mechanism includes a toner storage box, a funnel head and a sealing cover for placing toner, and are connected in sequence by a threaded rotation.

[0006] It also includes a dredging mechanism, which includes a counterweight ball placed in the powder storage box, the outer diameter of which is larger than the diameter of the powder outlet of the funnel head, and a dredging rod connected to the outside of the counterweight ball, facing the powder outlet of the funnel head.

[0007] To achieve the above technical solution, a counterweight ball is used to move the unblocking rod, allowing the unblocking rod to move around at the powder outlet of the funnel head, thereby improving the flowability of the carbon powder in the funnel head. Compared with the existing technology, this device uses the unblocking rod that moves around to unclog the funnel head, avoiding blockage and preventing excessive powder output that could cause dust.

[0008] Furthermore, the bottom of the powder storage box is concave and truncated cone-shaped, forming a stabilizing groove.

[0009] The above technical solution improves the stability of the powder storage box when it is square.

[0010] Furthermore, the surface of the powder storage box is connected to a vertical transparent plate, and the transparent plate is raised with a height of at least two millimeters.

[0011] Implementing the above technical solution makes it easier to determine the remaining amount of toner in the toner storage box.

[0012] Furthermore, a rubber strip is connected between the outer side of the sealing cap and the funnel head, and the length of the rubber strip is at least three centimeters.

[0013] The above technical solution ensures that the sealing cap will not be lost accidentally.

[0014] Furthermore, the lengths of the counterweight ball and the unblocking rod are equal to or greater than the distance from the powder outlet of the funnel head to the bottom of the powder storage box.

[0015] The above technical solution ensures that the unblocking rod is always inside the funnel head.

[0016] Furthermore, a positioning frame is connected to the powder storage box at the top of the counterweight ball, and the unblocking rod passes through the strip-shaped through hole of the positioning frame.

[0017] The above technical solution avoids the counterweight ball from moving into the funnel head and obstructing the powder output.

[0018] The technical effects and advantages of this utility model are as follows:

[0019] 1. This utility model uses a counterweight ball to drive the unblocking rod to move, so that the unblocking rod can move around at the powder outlet of the funnel head, thereby improving the flowability of carbon powder in the funnel head.

[0020] 2. Compared with the prior art, this utility model uses a dredging rod that moves in all directions to unclog the funnel head, thus avoiding blockage and preventing excessive powder output that could cause dust. Attached Figure Description

[0026] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0027] Example 1

[0028] Refer to the attached diagram in the instruction manual. Figure 1-4 The present invention provides a toner box, including a toner replenishing mechanism 1. The toner replenishing mechanism 1 includes a toner storage box 110 for toner storage, a funnel head 111 and a sealing cover 112, which are connected in sequence by a threaded rotation.

[0029] It also includes a dredging mechanism 2, which includes a counterweight ball 210 placed in the powder storage box 110, the outer diameter of which is larger than the diameter of the powder outlet of the funnel head 111, and a dredging rod 211 connected to the outside of the counterweight ball 210, facing the powder outlet of the funnel head 111. The length of the counterweight ball 210 and the dredging rod 211 is equal to or greater than the distance from the powder outlet of the funnel head 111 to the bottom of the powder storage box 110. A positioning frame 212 is connected to the powder storage box 110 at the top of the counterweight ball 210, and the dredging rod 211 passes through the strip-shaped through hole of the positioning frame 212.

[0030] When in use, insert the powder outlet of the funnel head 111 into the powder inlet of the toner cartridge, then shake the toner storage box 110 to move the counterweight ball 210 along the positioning frame 212, and then the counterweight ball 210 drives the unblocking rod 211 to move and unblock the powder outlet of the funnel head 111.

[0031] Example 2

[0032] Refer to the attached diagram in the instruction manual. Figure 1 The difference between Embodiment 2 and Embodiment 1 is that: the bottom of the powder storage box 110 is concave and truncated cone-shaped to form a stabilizing groove; a vertical transparent plate 113 is connected to the surface of the powder storage box 110, and the transparent plate 113 is convex with a convex height of at least two millimeters; a rubber strip 114 is connected between the outer side of the sealing cover 112 and the funnel head 111, and the length of the rubber strip 114 is at least three centimeters.

[0033] When placing the toner box 110, make it square so that the groove at the bottom of the toner box 110 is placed on the table. Then, the toner content inside the toner box 110 can be observed through the transparent plate 113.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
