<P>PROBLEM TO BE SOLVED: To provide an air blower capable of easily adjusting dust suction force and jetting force. <P>SOLUTION: The air blower includes: an opening 2 for blowing and sucking dust; a suction chamber 6 having a suction fan 5 on which the suction force of a vacuum cleaner (not shown in the figure) acts and which is operated by the suction force; a jetting chamber 10 having a jetting fan 9 for generating the jetting force; a rotary shaft 13 for transmitting the power of the suction fan 5 to the jetting fan 9; an air intake 7 having a lid body 17 for fetching outside air for rotating the suction fan 5 and changing the amount of the outside air to be taken in; and a switch 14 for switching the suction of the air or the jetting of the air from the opening 2. By having a user operate an operation means 20 disposed at one end of a hose (not shown in the figure) of the vacuum cleaner and capable of arbitrarily changing the drive amount of an electric fan (not shown in the figure) of the vacuum cleaner, the suction and jetting of the air are switched by the switch 14, the drive amount of the lid body 17 is changed, and thus the suction force and the jetting force are easily adjusted. <P>COPYRIGHT: (C)2013,JPO&INPIT |
