Description

Technical Field

[0001] The utility model relates to the technical field of powder feeders, in particular to a powder tank powder feeder. Background Art

[0002] like Figure 1 and Figure 2 The figure shows a conventional toner cartridge sealing device, which includes a frame 10, a closing structure 20 installed in the frame 10, and a spring 30 sleeved on the outside of the closing structure 20. The frame 10 is provided with a slide groove 101, one end of the slide groove 101 is provided with a first through hole 102, and the other end of the slide groove is provided with a second through hole 103. The closing structure 20 can move along the slide groove 101 between a closed position closing the first through hole 102 and an open position opening the first through hole 102. Figure 1 FIG. 2 is a schematic diagram showing the closure structure 20 in the closed position. Figure 2 The figure shows a schematic diagram of the closing structure 20 in the open position. Two buckle parts 201 are provided at one end of the closing structure 20, and the buckle parts 201 pass through the second through hole 103. When the closing structure 20 is in the closed position, the first through hole 102 is closed, thereby preventing the toner in the toner cartridge from leaking, and the buckle parts 201 are buckled on the frame 10 to prevent the closing structure 20 from falling off the frame 10. A hollow part 202 is provided between the two buckle parts 201, and strip parts 203 are provided on both sides of the hollow part 202 to connect with the buckle parts 201.
