[0002] Toner cartridges, also known as laser toner cartridges or laser toner cartridges, are important consumable components in laser printers. They mainly contain toner, which is a fine dry mixture of plastic particles, carbon powder and black or other colorants, which is used to make actual images on paper. The toner cartridge transfers the toner to the paper through the electrostatically charged photosensitive drum unit, and is fused to the paper by the heated roller during the printing process to complete the printing process. When using existing toner cartridges, it is often necessary to add toner to the toner cartridge. Since existing toner cartridges only use relatively simple switch parts to seal the powder inlet, the switch parts are easy to loosen and fall off, causing the toner in the toner cartridge to leak out, increasing costs and affecting the use effect of the toner cartridge. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a toner cartridge, which solves the problem that when the toner cartridge in the prior art is in use, it is often necessary to add toner to the toner cartridge. Since the prior art toner cartridge only uses a relatively simple switch component to seal the powder inlet, the switch component is easy to loosen and fall off, causing the toner in the toner cartridge to leak out, increasing costs and affecting the use effect of the toner cartridge.

[0036] The moving component 8 includes a mounting groove 801, which is provided on the lower surface of the housing 1, and a sliding plate 802 is slidably arranged in the mounting groove 801;

[0037] Connection grooves 803 are provided on both sides of the top of the installation groove 801, and the upper ends of the two connection grooves 803 are respectively connected to the corresponding slots 3;

[0038] Support plates 804 are fixedly installed on both sides of the upper surface of the slide plate 802 . The upper surfaces of the two support plates 804 respectively penetrate the corresponding connection grooves 803 and are fixedly connected to the corresponding plug-in plates 4 .

[0039] A screw rod 805 is rotatably installed between the two sides of the inner wall of the installation groove 801 , and the slide plate 802 is threadedly arranged on one side of the rod body of the screw rod 805 .

[0040] Through the above technical solution, after the staff pours the toner into the shell 1 through the powder inlet 2, the staff moves the bracket 6 to drive the sealing cover 7 to move along the direction of the connecting plate 5, so that the sealing cover 7 moves to the position of the powder inlet 2. Then the staff rotates the screw 805 to drive the slide plate 802 to move along the installation groove 801 by screwing it in, so that the sealing cover 7 moves to the opening of the powder inlet 2 and presses against the powder inlet 2, so that the sealing cover 7 can effectively cover the powder inlet 2, avoid leakage of toner in the toner cartridge, reduce costs, and do not affect the use effect of the toner cartridge.

[0041] In this embodiment, one end of the screw rod 805 passes through the mounting slot 801 and is fixedly mounted with the rotating wheel 9 .
