Foot air-extracting and inflating machine

Abstract

A foot air-extracting and inflating machine includes a machine body having a support frame provided with a pivot support member for pivotally assembling a pedal having its underside disposed with two push-rod pivot support members. The machine body is installed inside with two pumps respectively provided with a piston having a push rod pivotally combined with the push rod pivot support member of the pedal. Each pump has its lower side juxtaposed with two one-way valves respectively positioned in the two-way direction and having its lower side bored with air holes covered with a valve plate. An air suction tube and an exhaust tube are assembled under each pump, respectively aligned to the one-way valves. An air suction manifold communicates the two air suction tubes and connected with an air suction outer tube, and an exhaust manifold communicates the two exhaust tubes and connected with an exhaust outer tube.

1 . A foot air-extracting and inflating machine comprising:
 a machine body fixed with a support frame at its upper center, said support frame provided thereon with a pivot support member;   a pedal pivotally assembled over said machine body, said pedal disposed with a pivot to be pivotally combined with said pivot support member on said support frame of said machine body, said pedal having its underside provided with two push-rod pivot support members;   two pumps positioned in an interior of said machine body, each said pump installed inside with a piston, said piston provided with a push rod extending out of said machine body, said push rod having its upper end disposed with a pivot to be pivotally combined with said push-rod pivot support member of said pedal, each said pump having its lower side juxtaposed with two one-way valves respectively in a positive direction and in a reverse direction, an air suction tube and an exhaust tube positioned under each said pump and respectively aligned to each said one-way valve, said two air suction tubes communicating with each other by means of an air suction manifold, said two exhaust tubes communicating with each other by means of an exhaust manifold;   an air suction outer tube connected with said air suction manifold of said pumps; and   an air inflation outer tube connected with said exhaust manifold of said pumps.
