Vacuum blower
Provided is a vacuum blower capable of increasing the volume of air by sucking in more air from a suction inlet when performing a suction operation as a vacuum blower, and capable of increasing the initial speed (suction speed) of an object to be sucked in the vicinity of the suction inlet. In addition, when the vacuum blower is used as a blower for blowing operation, the vacuum blower can blow air with high straightness from a spraying opening. In addition, the vacuum blower can quickly switch between suction operation and blowing operation. An inner pipe arranged on the inner side of an air pipe slides relative to the air pipe, so that the two end parts of the inner pipe are tightly attached to the two end parts (inflection parts), opposite to the two end parts of the inner pipe, of an air nozzle, one spraying opening is blocked, the other spraying opening is opened, and pressure air generated by an air blower is sprayed out along the inner side of the inner pipe. In this way, switching between the suction state and the spraying state is achieved.
本发明提供一种真空鼓风机，该真空鼓风机在作为真空风机进行抽吸操作时，能够通过从吸入口吸入更多空气而增大风量，而且能够增大吸入口附近的被吸物初始速度(吸入速度)。此外，在作为鼓风机进行喷吹操作时，该真空鼓风机能够自喷出口喷出平直度较高的风。另外，该真空鼓风机能够进行抽吸操作和喷吹操作的快速切换。通过使设于风管内侧的内管相对于风管滑动，使得内管的两端部分与与该内管两端部分相对的风嘴的两端部分(回折部分)紧贴，并使得其中一个喷出口堵塞，而另一个喷出口开放，从而使得鼓风机产生的压力风沿内管内侧喷出。如此，实现吸入状态和喷出状态的切换。
