Abstract

The present invention is to provide a kind of hand-held air pump with pumping and inhaling capacity, comprising a pneumatic cylinder (10), a reciprocating component (20), a pumping unit (30) and a valve unit (40). The above-mentioned pneumatic cylinder (10) has the first end and the second end, and it contains a space (11) through the first end and the second end. The above-mentioned reciprocating component (20) is arranged at one end of the pneumatic cylinder (10) to be manipulated by users. The pumping unit (30) is pivotally coupled with the other end of the pneumatic cylinder (10), and it has two holes inside. One hole communicates with the pumping device (32) and the other hole communicates with the outside. The valve unit (40) has the first air passage (41) and the second passage (42) corresponding to the said two holes. The first air passage (41) has a one-way valve (411) and communicates with the space (11). The second passage (42) communicates with the valve unit (40) periphery that is equipped with a one-way valve (441). The valve unit (40) is arranged between the pneumatic cylinder (10) and pumping unit (30), and it can rotate between the first position and the second position by the drive of the pneumatic cylinder (10). The hole on the pumping unit (30) and communicating with the pumping device (32) can alternatively correspond with the first air passage (41) and the second passage (42). Thus, the air pump can perform the pumping or inhaling process.
