Abstract:
1. A portable air blower sending wind generated in a main body, comprising: a first pipe having a first outlet opening communicating with the main body, the first pipe discharging wind generated in the main body through the first outlet opening; and a second pipe having a larger diameter than that of the first pipe, the second pipe being attached movably in the axial direction to the outer circumference of the first pipe and having a second outlet opening having a larger diameter than that of the first outlet opening, wherein the second pipe is moved relative to the first pipe to dispose the second outlet opening upstream or downstream of the first outlet opening; the second pipe has an inflow window disposed upstream of the first outlet opening, the inflow window enabling air to flow from the outside into the second pipe; wind generated in the main body is sent from the first outlet opening in the case where the second outlet opening is disposed upstream of the first outlet opening; and wind generated in the main body is sent through the first outlet opening from the second outlet opening while wind flowing from the inflow window into the second pipe due to negative pressure is sent from the second outlet opening in the case where the second outlet opening is disposed downstream of the first outlet opening.
