    • 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.
    • 提供喷嘴。 喷嘴包括气体注入单元,筛体和衍生单元。 气体注入单元适于将气体注入含有粉末的粉末容器中。 筛体包括圆柱体,过滤器和叶片。 气缸具有用于将气缸与粉末容器连通的连通孔。 过滤器设置在气缸的底部。 叶片适于在将气体注入粉末容器中时通过连通孔从粉末容器中搅动引入圆筒的粉末,以使粉末通过过滤器。 刀片能够围绕与过滤器相邻的旋转轴线旋转,靠近过滤器。 衍生单元适于将通过过滤器的粉末衍生出粉末容器。
