Abstract
An air pump set includes an air pump, at least two air distributors and a pressure reducer. At least two air distributors are serially connected with the air pump for further distributing the pressurized air to respective air-requiring targets. The pressure reducer is serially connected between any adjacent two of the at least two distributors for reducing the pressure of the pressurized air to a downstream one of any adjacent two of the at least two distributors. The pressure reducer includes a hollow cylinder and a cylinder core. The hollow cylinder includes a first pair of inlet and outlet and a second pair of inlet and outlet. The cylinder core is loosely fitted within the hollow cylinder, and comprises a first air channel and a second air channel. The cylinder core is rotatable between a first position and a second position relative to the hollow cylinder.
