Motor direct drive air pump and related applications thereof

Abstract

A motor direct drive air pump comprises a housing, a first shaft, and a second shaft. The housing is formed with a left space and a right space; one of the spaces is a compression chamber having an air inlet and an air outlet; the other space has a transmission chamber and a driving chamber; stators are disposed in the driving chamber. A first shaft is disposed through a central partition of the housing; a first impeller is embedded at a portion of the first shaft located in the compression chamber, while a first gear is embedded at a portion of the first shaft located in the transmission chamber, and rotors are embedded at a portion of the first shaft located in the compression chamber. A second shaft is disposed through the central partition of the housing; a second impeller is embedded at a portion of the second shaft located in the compression chamber, while a second gear is embedded at a portion of the second shaft located in the transmission chamber, and the second impeller and the second gear are respectively coupled to the first impeller and the first gear. Therefore, a power outputted from a motor directly drives the first and the second impellers and allow the air pump to operate, without any additional coupling.
