Abstract
A multi-stage electric gas pump includes a driving mechanism and an eccentric shaft including a main body having a longitudinal axis, a first eccentric portion, and a second eccentric portion, wherein the first eccentric portion and the second eccentric portion are fixed on the main body. The eccentric shaft is driven by the driving mechanism to produce a first circular movement of the first eccentric portion around the longitudinal axis and a second circular movement of the second eccentric portion around the longitudinal axis, wherein the second circular movement is synchronized with the first circular movement. The multi-stage electric gas pump further includes a first cylinder, a second cylinder, and a third cylinder. The cylinders in three stages are driven by the eccentric shaft so as to achieve three-stage pressurization of gas.
