AIR SUCTION/INJECTION DEVICE AND VACUUM CLEANER COMPRISING THE SAME

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 is configured that the interior of the main unit constitutes a main passage of air, and the interior of an injection passage section provided in the main body constitutes a sub-passage. Once a suctioned airstream is created in the main passage, a power fan inside of a suction chamber is rotated, and in conjunction with such a rotation, an injection fan is rotated so that an injecting airstream is created in the sub-passage. In such case, a passage switching section composed of a valve member provided in the location of joining the main passage and the sub-passage is switched to easily switch between a creation of an injecting airstream and a creation of a suctioned airstream.
