Abstract

An automatic self-sealing balloon, includes a balloon body, a sealing member and a water injection port arranged on the balloon body. A cavity is formed inside the balloon body, and the water injection port communicates the cavity with external environment. The sealing member is provided in the cavity, and the sealing member is made from materials of less dense than water. The sealing member's peripheral contour is greater than the water injection port's inner contour. When the cavity of the balloon body is filled with water or inflated with gas to a full extent state, the sealing member blocks the water injection port to realize automatic self-sealing function.

Claims

exact text as granted — not AI-modified
1 . An automatic self-sealing balloon, comprising a balloon body and a water injection port arranged on the balloon body,
 wherein a cavity is formed inside the balloon body, and the water injection port communicates the cavity with external environment;   wherein a sealing member is provided in the cavity, and the sealing member is made from materials of less dense than water; and   wherein the sealing member's peripheral contour is greater than the water injection port's inner contour.   
     
     
         2 . The automatic self-sealing balloon according to  claim 1 , wherein the sealing member is of a spherical structure and the water injection port is of a columnar structure. 
     
     
         3 . The automatic self-sealing balloon according to  claim 1 , wherein the sealing member is made from foam materials. 
     
     
         4 . The automatic self-sealing balloon according to  claim 1 , wherein the sealing member is made from plastic materials. 
     
     
         5 . The automatic self-sealing balloon according to  claim 1 , wherein the balloon body is made from rubber materials. 
     
     
         6 . The automatic self-sealing balloon according to  claim 1 , wherein the balloon body and the water injection port are integral. 
     
     
         7 . The automatic self-sealing balloon according to  claim 1 , wherein a ratio of the water injection port's cross-sectional diameter to the sealing member's diameter is 1:1.5. 
     
     
         8 . The automatic self-sealing balloon according to  claim 1 , wherein patterns are printed on an outer surface of the balloon body.
