When the cover 60 and the cover 30 are combined together, the two engaging arms 64 engage with the two engaging portions 14 of the cover 30 of the housing 10, and the plurality of ribs 621 of the abutting portion 62 press against the sliding piece 40 at the closed position and compress and deform the sealing piece 50, as shown in fig. 6, in this case, the sealing piece 50 can actually close the powder outlet 12, so that the toner cartridge 1 cannot leak powder randomly, and the protrusion 44 of the sliding piece 40 extends into the through hole 625 of the abutting portion 62 and the positioning rib 623 extends into the hollow portion 42 of the sliding piece 40, so that the sliding piece 40 cannot easily slide from the closed position to change the powder outlet 12 from the closed state to the open state when the cover 60 and the cover 30 are combined, and therefore, the toner cartridge 1 has no possibility of powder leakage. In fact, the protruding ribs 621 are provided to help the abutting portion 62 press against the sliding piece 40 more reliably, so in other possible embodiments, the protruding ribs 621 may be omitted, and the abutting portion 62 or the protruding ribs 621 may press against the sliding piece 40 directly, and in addition, as long as the abutting portion 62 or the protruding ribs 621 can press against the sliding piece 40 reliably, so that the sliding piece 40 does not slide easily when the clip cover 60 is combined with the cover member 30, the positioning rib 623 of the abutting portion 62 does not need to extend into the hollow portion 42 of the sliding piece 40, or the positioning rib 623 and the hollow portion 42 may be omitted, and similarly, the protruding portion 44 of the sliding piece 40 does not need to extend into the through hole 625 of the abutting portion 62, or the protruding portion 44 and the through hole 625 may be omitted. It should be noted that, in the embodiment, when the clamping cover 60 is combined with the cover 30, the protruding structure of the positioning rib 623 is used to extend into the hollow portion 42, and the protruding structure of the protruding portion 44 is used to extend into the through hole 625, so that if the sliding piece 40 is not completely located in the closed state, the positioning rib 623 and the protruding portion 44 will be abutted against other unexpected positions, and the clamping cover 60 cannot be smoothly combined with the cover 30, which can be used to remind a user or an assembler that the sealing member 50 does not completely close the powder outlet 12, and the clamping cover 60 needs to be covered by the sliding piece 40 after the sliding piece 40 is completely located in the closed state to avoid powder leakage.

When the user wants to mount the toner cartridge 1 on the electronic imaging device, the user needs to first detach the cover 60 from the cover 30, and then only needs to press the toggle parts 643 of the two clamping arms 64 of the cover 60 inward to make the hook parts 641 at the top ends of the clamping arms 64 detach from the clamping parts 14 outward, so that the cover 60 can be easily detached from the cover 30, the process is simple and convenient, at this time, the sliding piece 40 is not pressed by the protruding rib 621 of the top part 62, as shown in fig. 7, and the sealing member 50 is only slightly deformed by the compression of the sliding piece 40; as mentioned above, the toner cartridge 1 is not likely to leak toner at all, and therefore the original thickness of the sealing member 50 is not too thick, so that when the sliding piece 40 is pushed by the corresponding component in the electronic imaging device, the sliding piece 40 can smoothly slide from the closed position to the open position, so that toner can be discharged from the toner outlet 12, and similarly, when the electronic imaging device does not need to supply toner from the toner cartridge 1, the sliding piece 40 can smoothly slide from the open position to the closed position, and the sealing member 50 is not easily pushed by the edge of the toner outlet 12 to tilt. In other possible embodiments, the structure of the clip cover 60 can be changed, for example, the clip arm 64 can be provided without the toggle portion 643, and the user only needs to place a finger on the hook portion 641 and apply an outward force to pull the hook portion 641 open during the practical operation, so that the hook portion 641 can be disengaged from the clip portion 14; the inner side of the latch arm 64 can be provided with a groove for the latch portion 14 to extend into, so as to combine the clip cover 60 with the cover member 30, in which case the hook portion 641 can be omitted, or the latch portion 14 can be a concave latch hole for the hook portion 641 of the latch arm 64 to extend into, or the clip cover 60 can be combined with the cover member 30.

The present invention is capable of other embodiments, and various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
