Abstract
A nozzle is provided. The nozzle includes a gas injection unit, a sieve body, and a derivation unit. The gas injection unit is adapted to inject a gas into a powder container containing a powder. The sieve body includes a cylinder, a filter, and a blade. The cylinder has a communication aperture for communicating the cylinder with the powder container. The filter is disposed at a bottom of the cylinder. The blade is adapted to agitate the powder introduced into the cylinder from the powder container through the communication aperture upon injection of the gas into the powder container to allow the powder to pass through the filter. The blade is rotatable about a rotation axis that intersects with the filter in proximity to the filter. The derivation unit is adapted to derive the powder passed through the filter out of the powder container.
