1. a light inflator is characterized in that, comprising:

  • One cylindrical shell, first end that it is relative and second end are provided with a loam cake and a lower cover respectively, and this lower cover is covered with inlet hole with second end sealing of said cylindrical shell on this;

    One gas transmission bar has the gas distribution channel of its first end of axial perforation and second end;

    One piston apparatus;

    Include a piston body and a check valve;

    The external diameter of this piston body is provided with piston ring, and this piston body is located at second end of said gas transmission bar, and this check valve is located between this gas transmission bar second end and this piston body;

    And this piston body and gas transmission bar second end are arranged in this cylindrical shell, said piston body is provided with a center hole and at least one through hole that is positioned at this piston body downside;

    Said check valve include one possess interior space a check valve seat and a check valve block;

    This check valve seat is the cylindrical shell of step shape;

    And have one be communicated with space in this central hole;

    The position of this central hole is provided with at least one outstanding bottom surface, space in this but does not cover the projection of this central hole;

    One end of this check valve is inserted in the gas distribution channel of this gas transmission bar second end, and the other end is inserted in this piston body, and said check valve block is located at the interior space of this check valve seat and can between the projection of the center hole of this piston body and check valve seat, be moved;

    One head has the gas flow that connects both sides, and this head is located at first end of this gas transmission bar, and the gas distribution channel of this gas flow and gas transmission bar is communicated;

    One valve joint is located at this head and is communicated with this gas flow;

    When said cylindrical shell moves with respect to this gas transmission bar with the direction of leaving this head;

    Make air get into cylindrical shell through the vent of this loam cake;

    And get into said cylindrical shell bottom through the through hole of this piston body;

    When cylindrical shell moves with respect to this gas transmission bar with the direction towards this head, then make the gas distribution channel of the air of this cylindrical shell bottom, and then flow out by this head and valve joint through said center hole and this gas transmission bar of check valve entering.
