Abstract

A cooling structure of an air cushion contains a body, and the body includes a plurality of air units, and each air unit includes a recess disposed on a top surface thereof, such that when a contacting portion of a user abuts against the body, the plurality of air units contact with the contacting portion, and the recesses form an airing space to cool a heat.

1 . A cooling structure of an air cushion comprising a body, and the body including a plurality of air units, and each air unit including a recess disposed on a top surface thereof, such that when a contacting portion of a user abuts against the body, the plurality of air units contact with the contacting portion, and the recesses form an airing space to cool a heat. 
     
     
         2 . The cooling structure of the air cushion as claimed in  claim 1 , wherein a top surface of the recess is lower than that of the air unit. 
     
     
         3 . The cooling structure of the air cushion as claimed in  claim 1 , wherein the air units are connected together to achieve an arc structure and are capable of being arranged on various types of air cushions. 
     
     
         4 . The cooling structure of the air cushion comprises a number of air units and a plurality of recesses fixed on a top surface of the body, and the plurality of recesses communicate with each other; such that when a contacting portion of a user abuts against the body, the number of air units contact with the contacting portion, and the recesses form an airing space to cool a heat.
