Vertical vacuum cleaner

摘要

The present invention discloses an upright vacuum cleaner which comprises a cleaner body (100), a ground brush (200), a dust collection chamber (300), a conversion valve and a pipeline system. The conversion valve (400) is disposed at the outside of the back surface of the cleaner body (100) and is located at an inward recess between the dust collection chamber (300) and the ground brush (200). The conversion valve (400) is provided with a first air inlet, a second air inlet and an air outlet of the conversion valve. The pipeline system comprises a suction soft pipe (501), an air duct (203) of the floor brush, a machine body air inlet duct (503), a machine body air outlet duct (504) and a motor chamber exhaust pipe. The pipeline system further comprises a motor chamber air inlet pipe (505) of which one end is connected with the air duct (203) of the ground brush, and the other end is connected with the first air inlet (505) of the conversion valve after passing through the motor chamber and being bend upward against the outside of the back surface of the floor brush. The upright vacuum cleaner can clean not only the floor but also other places above the floor. The upright vacuum cleaner provides an unblocked air flow, has a compact structure, saves spaces, is convenient to package, and is not easily damaged.
