Toner feeding barrel with toner feeding holes and toner feeding box

Abstract

The invention discloses a toner feeding barrel with toner feeding holes and a toner feeding box and belongs to the field of printer toner feeding boxes. The toner feeding barrel with the toner feedingholes comprises a toner barrel. The toner feeding barrel further comprises an upper cover, a piston, a first toner feeding hole, a second toner feeding hole, a conical sealing plug, and a conical opening; the upper cover is connected with the upper end of the toner barrel; the piston is slidingly connected into the toner barrel in a sealed manner; the first toner feeding hole is formed in the upper cover; the second toner feeding hole is formed in the piston and is corresponding to the first toner feeding hole; the conical sealing plug is arranged at the lower end of the second toner feeding hole; and the conical opening is formed in the lower end of the second toner feeding hole and is corresponding to the conical sealing plug. According to the toner feeding barrel with the toner feeding holes of the invention adopted, the conduction of the toner barrel can be realized through the first toner feeding hole and the second toner feeding hole, so that toner feeding can be carried out;after the toner feeding is completed, resetting can be performed; the conical sealing plug can be tightly attached onto the conical opening under the action of a tension spring so as to plug the conical opening; and toner feeding can be carried out without disassembling the upper cover required, and therefore, toner feeding efficiency is high.

Description

technical field [0001] The invention relates to the technical field of a powder filling box for a printer, in particular to a powder filling bucket and a powder filling box with powder filling holes. Background technique [0002] The HP laser printer adopts flash charging technology to add powder. The powder injection port of HP 1005w is located on the right side of the fuselage. You only need to open the cover above the powder injection port to fill the powder, and insert the powder container into the powder injection port. There is a chip at the insertion end of the toner box that is electrically connected to the printer, and the entire process of toner supply can be completed within a few seconds. The hole on the printer is punched into the toner box of the printer, so that the toner box can be reused, but the toner filling box in the prior art still has certain defects. When the powder in the toner box is used outside, it needs to be disassembled The upper cover and the...

Problems solved by technology

[0002] The HP laser printer adopts flash charging technology to add powder. The powder injection port of HP 1005w is located on the right side of the fuselage. You only need to open the cover above the powder injection port to fill the powder, and insert the powder container into the powder injection port. There is a chip at the insertion end of the toner box that is electrically connected to the printer, and the entire process of toner supply can be completed within a few seconds. The hole on the printer is punched into the toner box of the printer, so that the toner box can be reused, but the toner filling box in the prior art still has certain defects. When the powder in the toner box is used outside, it needs to be disassembled The upper cover and the piston then fill the powder bucket with powder, and the upper cover needs to be disassembled. The operation process is cumbersome and the powder filling efficiency is low.
