[0002] In general existing toner cartridges, its cover has a powder outlet for carbon powder discharge, a slidable slide is located on the cover, and a foam is located on the slide, when the slide slides When the position corresponds to the powder outlet, the foam can seal the powder outlet so that the carbon powder in the toner cartridge will not leak out; however, if the thickness of the foam is not thick enough, the foam will be applied to the powder outlet Insufficient pressure at the mouth, so that there is a gap between the foam and the powder outlet, and the toner will fall out from the gap, resulting in powder leakage. However, if the foam is too thick, it can be sealed out. powder outlet, but the price paid is that the resistance of the slider will be relatively large during the sliding process, and even during the sliding process, the foam will be warped by the edge of the powder outlet As a result, the foam is damaged or deformed and cannot completely seal the powder outlet, and there will still be powder leakage
In actual manufacturing, due to the tolerances in the dimensions of each component, it is difficult to grasp the exact foam thickness

Embodiment Construction
[0036] Please refer to figure 1 , figure 2 , the toner cartridge 1 provided by the first preferred embodiment of the present invention includes a housing 10, a sliding piece 40, a sealing member 50, a clip cover 60 and a control circuit board 70 disposed on the housing 10 At the end of the , it is important to note that at the figure 1 , figure 2 In the figure, the toner cartridge 1 is shown in the drawings with its bottom side facing upwards and its top side facing downwards in the drawings. Therefore, synonyms such as "upper" in describing components in the specification mean that they are facing downwards in the drawings, Synonyms such as "below" to describe elements mean that they are oriented upward in the drawings.
[0037] The bottom side of the housing 10 has a powder outlet 12, and the two sides of the housing 10 respectively have a plate-shaped protruding engaging portion 14. In this embodiment, the housing 10 has a cylinder body 20 and A cover 30, the barrel 2...

The invention discloses a powdered ink box comprising a casing, a sliding piece, a sealing piece and a clamp cover, the bottom side of the casing is provided with a powder outlet, two sides of the casing are provided with two clamping parts, and the sliding piece is arranged in the casing and can slide between an open position and a closed position. The sealing piece is arranged on the slide piece, when the sliding piece is located at the closed position, the powder outlet is sealed by the sealing piece, the clamp cover is provided with a contact-abutting part and two clamping arms extending upward from two sides of the contact-abutting part, the two clamping arms are clamped on the two clamping parts of the casing, the contact-abutting part abuts the sliding piece located at the closed position to compress and deform the sealing piece, thereby, the powder outlet is assuredly sealed by the sealing piece, and when the clamp cover is removed, the sliding piece can glidingly slide between the open position and the closed position.
Description
technical field [0001] The invention relates to an electronic imaging device, in particular to a toner cartridge for the electronic imaging device. Background technique [0002] In general existing toner cartridges, its cover has a powder outlet for carbon powder discharge, a slidable slide is located on the cover, and a foam is located on the slide, when the slide slides When the position corresponds to the powder outlet, the foam can seal the powder outlet, so that the carbon powder in the toner cartridge will not leak out; however, if the thickness of the foam is not thick enough, the foam will give the toner Insufficient pressure at the mouth, so that there is a gap between the foam and the powder outlet, and the toner will fall out from the gap, resulting in powder leakage. However, if the foam is too thick, it can be sealed out. powder outlet, but the price paid is that the resistance of the slider during the sliding process will be relatively large. As a result, the...
