1. a nonlinear check valve structure, is characterized in that, comprising:

  • Two plastic cement inner membrances, these two plastic cement inner membrances are placed in the air sealing body that is made up of two plastic cement adventitias;

    Described inner membrance seals multiple camber lines of formation, described camber line comprises the multiple left camber line being positioned at side and the multiple right camber line being positioned at opposite side, described left camber line and right camber line arrange in left-right asymmetry mode, the bottom terminal of described left camber line and right camber line establishes a breach, an arc concave surface of camber line below this breach next-door neighbour opposite side, organize arrangement so that this left and right collocation mode is from top to bottom more, form nonlinear check valve structure;

    When sealing body is inflated via this air-stopping valve structure, air can flow to camber line along camber line of described left camber line and right camber line from after the air intake that described inner membrance air-stopping valve structure is preset enters, and be subject to the stop of this arc concave surface and proceed to this breach, namely be directed to the lower camber line of described opposite side camber line by the upper camber line of opposite side camber line by this breach, and flow into next breach, form right camber line, breach, left camber line, breach and take turns the air outlet of turning over and flowing to bottom described inner membrance by the mode of a right left side or left and right in turn and enter sealing body.
