ELECTRIC AIR PUMP POWERED BY AN EXTERNAL POWER SOURCE

Abstract

ELECTRIC AIR PUMP POWERED BY AN EXTERNAL POWER SOURCE The invention relates to an electric air pump powered by an external power source, comprising an outer casing (10), a pump assembly, and a control module. The pump assembly is located inside the outer casing (10). The control module is located in the outer casing (10) and comprises a printed circuit board, a power supply port (32), and a start switch (33). The power supply port (32) is electrically connected to the printed circuit board and can be connected to an external power source. The start switch (33) is electrically connected to the printed circuit board and is designed to control whether the printed circuit board is electrically connected to the pump assembly. Therefore, the electric air pump does not require an integrated battery. Figure to be published with the abstract: Figure 1
