Abstract
A valve connector of an air pump includes a case with a channel and a guiding room therein. The channel is communicated with the guiding room. Two valve connector assemblies are provided in the case, each of which has a tunnel communicated with the guiding room, wherein the tunnels form apertures on a sidewall of the guiding room. A switching device is received in the guiding room and pivoted on the sidewall of the guiding room. The switching device has two arms on opposite sides of a pivot axle thereof. The arms are moved toward or away from the apertures respectively when the switching device is swung to close or open the apertures.
