Ball with an inflation device

Abstract

A ball with an inflation device includes a ball body and an inflation unit disposed in the ball body. The ball body has a reinforcement cavity on an inner wall thereof to accommodate the inflation unit and communicate with the inflation unit for air inflation. The inflation unit has an inflation body coupled to the reinforcement cavity of the ball body. An air chamber is formed between the ball body and the inflation body. The inflation body has an air inlet, an inflation inlet and leakage-proof members respectively coupled to the air inlet and the inflation inlet. The inflation inlet communicates with the inside of the ball body. When in use, the user presses down the air inlet of the press portion with his/her finger, the air in the air chamber will pass the leakage-proof member into the ball body. When the user releases his/her finger, the leakage-proof member is used to stop the air in the inner space of the ball body from leakage. Outer air enters the air chamber through the air inlet. The operation is repeated to inflate the ball body, without using other tools

1 . A ball with an inflation device, comprises a ball body and an inflation unit disposed in the ball body;
 the ball body having an inner space for air inflation and a reinforcement cavity on an inner wall thereof, the inflation unit being disposed in the reinforcement cavity;   the inflation unit having an inflation body coupled to the reinforcement cavity of the ball body, an air chamber formed between the ball body and the inflation body;   the inflation body having an air inlet, an inflation inlet and leakage-proof members respectively coupled to the air inlet and the inflation inlet, the inflation inlet of the inflation body being provided with a base, the base having an air passage communicating with the inner space of the ball body and the inside of the inflation body, another leakage-proof member and an elastic member being provided in the air passage to prevent air form leakage.   
     
     
         2 . The ball with an inflation device as claimed in  claim 1 , wherein the inflation unit has an air inlet, an inflation inlet and back pressure valves respectively coupled to the air inlet and the inflation inlet. 
     
     
         3 . The ball with an inflation device as claimed in  claim 1 , wherein the reinforcement cavity on the inner wall of the ball body is capable of supporting and maintaining the shapes of the ball body and the inflation body. 
     
     
         4 . The ball with an inflation device as claimed in  claim 1 , wherein the inflation unit is an undulating and resilient cylinder, and the inflation body is coupled to the reinforcement cavity on the inner wall of the ball body. 
     
     
         5 . The ball with an inflation device as claimed in  claim 1 , wherein the inflation unit is in a hemisphere shape, and the inflation body is coupled to the reinforcement cavity on the inner wall of the ball body. 
     
     
         6 . The ball with an inflation device as claimed in  claim 1 , wherein the inflation unit is in a sphere shape. 
     
     
         7 . The ball with an inflation device as claimed in  claim 1 , wherein the inflation unit is in a dish-like shape fixed on the inner wall of the ball body and is not detachable. 
     
     
         8 . The ball with an inflation device as claimed in  claim 1 , wherein the base of the inflation body has engaging rings at two ends thereof to secure the ball body and the inflation body. 
     
     
         9 . The ball with an inflation device as claimed in  claim 1 , wherein the inflation body and the ball body are detachable, the base of the inflation body has threads thereon, and the reinforcement cavity on the inner wall of the ball body is provided with a threaded base.
