<p>The present invention provides a technology, which is capable of easily switching between the vacuum function and the blower function of the vacuum cleaner with a simple configuration, and is also capable of effectively utilizing the blower function even in the various situations. Typical air suction/injection device (10A) is configured that the interior of the main unit (111) constitutes a main passage (101) of air, and the interior of an injection passage section (112) provided in the main body (111) constitutes a sub-passage (102). Once a suctioned airstream is created in the main passage (101), a power fan (114b) inside of a suction chamber (115) is rotated, and in conjunction with such a rotation, an injection fan (114a) is rotated so that an injecting airstream is created in the sub-passage (102). In such case, a passage switching section composed of a valve member (116) provided in the location of joining the main passage (101) and the sub-passage (102) is switched to easily switch between a creation of an injecting airstream and a creation of a suctioned airstream.</p> |
