Air pump and vehicle

The utility model discloses an air pump and a vehicle. The air pump comprises a pump body; the cylinder sleeve is arranged in the pump body in an interference fit manner; and the sealing element is arranged between the pump body and the cylinder sleeve in a sealing manner. According to the air pump, the cylinder sleeve is in interference fit with the interior of the pump body, so that a gap between the cylinder sleeve and the pump body can be reduced, the sealing performance between the cylinder sleeve and the pump body can be improved, the sealing performance between the cylinder sleeve and the pump body can be further improved through the sealing piece, air leakage is avoided, and the air pump can work better. 本实用新型公开了一种气泵以及车辆，气泵包括：泵体；缸套，所述缸套过盈配合于所述泵体内；密封件，所述密封件密封设置于所述泵体和所述缸套之间。通过将缸套过盈配合在泵体内部，这样可以减小缸套与泵体之间的缝隙，从而可以提升缸套与泵体之间的密封性，而且密封件可以进一步地提升缸套与泵体之间的密封性，避免空气泄露，从而气泵可以更好地进行工作。
