Description

Multifunctional blower using rotating tools}

The present invention relates to a multifunctional blower that can be used in conjunction with rotating tools such as a lawnmower, a grinder, and a drill.

In general, a blower consists of a casing that has an impeller that generates a flow and guides the flow in and out of the impeller. There are several classification methods for blowers, but they are classified according to the characteristics of the flow passing through the most common impeller, and they are divided into axial flow fans, radial blowers, and mixed flow fans. These blowers are the one-piece blowers that are widely used at present, and representatively, there are BOSCH and DEWALT products. As a prior art, Patent Publication No. 10-2001-0016161 "Portable Blower" allows the operator to perform the blowing operation by transmitting the rotational force generated on the drive shaft inside the working rod according to the engine driving of the lawnmower to the rotation wheel of the blower. It maximizes the portability and mobility of the blower by making it easy to move between objects to be supplied with air or gas while carrying the blower. Utility Model Publication No. 20-2013-0001357 In "Portable Blower", the blower is the body Usually, you can put it on a desk or hang it with a suspender on a chair, and when you move, you can fix it to a waistband or use a suspender, which has the effect of emphasizing portability.
