<p>A device for measuring and dispensing powder materials comprises a slide housing (2), a slide (3) and an elastic element (6). The slide housing (2) is provided with a powder inlet slot (21). The slide (3) is provided with a measure slot (321). And the slide (3) is pressed against the slide housing (2) by the elastic element (6) to make said slide (3) move or rotate relative to said slide housing (2). Said slide (3) can move between the first position and the second position, on the first position, the measure slot (321) of the slide is in alignment with the powder inlet slot (21) of the slide housing and the powder is filled into the measure slot; on the second position, the measure slot (321) of the slide moves away from the powder inlet slot (21) of the slide housing and the powder is discharged from the measure slot. By use of the elastic element (6), it makes the slide (3) press against the slide housing (2) during moving so as to reduce the clearance between the slide (3) and the slide housing (2), makes the slide (3) move smoothly, and reduces the precesion demand of manufacture and assembly.</p> |
