Claim 1:
2. The multi-stage electric gas pump according to claim 1, wherein:
the first cylinder is configured to reciprocate in response to the first circular movement of the first eccentric portion to periodically pressurize gas drawn into the first chamber from an external environment of the multi-stage electric gas pump and discharge first pressurized gas out of the first chamber;
the second cylinder is configured to reciprocate in response to the first circular movement of the first eccentric portion to periodically pressurize the first pressurized gas drawn into the second chamber from the first chamber of the first cylinder and discharge second pressurized gas out of the second chamber; and
the third cylinder is configured to reciprocate in response to the second circular movement of the second eccentric portion to periodically pressurize the second pressurized gas drawn into the third chamber from the second chamber of the second cylinder and discharge third pressurized gas out of the third chamber.
