An elaborately designed miniature air compressor is composed of a motor unit, a compression unit, and an air collection unit. Several bladders installed in the compression unit are sequentially actuated by a compression vane with a thrust and pulling force imparted from priston like motion caused by revolution of an eccentrically installed follower rod such that air is continuously supplied to the air collection unit and ejected out of an air output port uniformly, stably, and adequately. Besides, all component units of the miniature air pump are combined together by two shackles in stead of using latch pins.

1. A miniature air pump comprising a motor unit, a compression unit, and an air collection unit;Wherein, said motor unit further including a main motor portion, a base, and a rotor portion, a rotating shaft which being extended out of said main motor portion is tunneling through the base and is coupled with said rotor portion whereat an eccentric hole being provided; several air inlet apertures is formed at the side of said base; Said compression unit further including a compression vane, a fixture, and several compression chambers, a follower rod which being extended out of the center of said compression vane is inserted into said eccentric hole formed on said rotor portion with a predetermined offset angle, said compression chamber being composed of a bladder, a flow check membrane, and a leak proof gasket, said compression chambers are conjoined with said compression vane by tenons each formed at the rear of rear of respective bladder mated with a corresponding mortise eye formed on said compression vane after tunneling through said fixture, a first check valve is installed on said fixture facing to said flow check membrane for each compression chamber; Said air collection unit including several flow pathways corresponding to said bladders, several membranes functioning as second check valves equipped at each outer side of said flow pathway, several guide slots each formed between said first check valve and said bladder, and an air output port at the topmost end thereof; With this structure, being driven by said motor unit, said compression vane is rotated by said follower rod and applies sequentially all bladders with a thrust and a pulling force imparted from said eccentrically installed follower rod, when one of said bladders is in full state, said first check valve is tightly closed by inner pressure of said compression chamber, while said flow check membrane functioning as a second check valve is opened by inner pressure of said corresponding compression chamer, and the stored air is introduced to said air collection unit, as soon as said full bladder is deformed, said first check valve is opened to input new air into said bladder via said guide slot, while said flow check, membrane is closed by a negative inner pressure thereof, such repeated actions are continued as long as said motor unit is energized, and air is therefore continuously and uniformly filled into said air collection unit and is ejected out of the pump from said air output port, said pump is characterized in that the number of said bladders and corresponding parts is optionally selective, and said bladders can be symmetrically disposed in various configuration.
