Regarding the structural composition, technical means and efficacy of this creation, we will further elaborate on the following examples with reference to the following: Please refer to Figures 1~7 for a preferred embodiment of the creation, as shown in the figure. As shown, the inflated sphere and structure of the present invention are mainly formed by a combination of a sphere (10) and a ball cover (20), which is molded by soft rubber or the like. It is integrally formed, so there is no conventional two-ball and synthetic type of joint on its surface, and a predetermined hole (11) is reserved at a specific position of the sphere (10), and the through hole (11) is The circumference is formed with a step ring portion (12) which is slightly different from the spherical surface, and the ball cover (20) is also molded by soft rubber, and the size and shape of the ball cover (20) are The through hole (11) of the spherical body (10) and the peripheral step ring portion (12) are matched, so that the outer edge surface of the ball cover (20) has an arc surface conforming to the spherical surface of the sphere (10), and the inner edge surface is formed with a curved surface. The sleeve portion (21) of the inner diameter of the through hole (11) of the ball body (10) can be embedded, and a soft valve body (22) having an inner convex shape is integrally formed at a central portion of the sleeve portion (21), and is soft. The center of the valve body (22) is provided with a gas valve hole (23) according to the demand, and the gas valve hole (23) is tightly combined by the material property of the soft valve body (22), and at the same time, the ball cover (20) The outer edge surface is opposite to the soft valve body (22) The position of the gas valve hole (23) is recessed with a mark (24), so that the ball needle (30) is selected to be inserted at the correct position, and the outer layer of the soft valve body (22) is covered with a layer of hard rubber material. The hard valve casing (25) can maintain the shape of the soft valve body (22), and the lower end of the hard valve casing (25) is open and does not cover the lower end of the soft valve body (22), so that the ball needle (30) ) is completely inserted through the soft valve body (22), whereby the structure of the ball (10) and the ball cover (20) is obtained through the peripheral step of the through hole (11) of the ball (10) (12) ) Apply glue to the inner edge of the inner edge of the ball cover (20), and then cover the adhesive seal group to form a complete inflatable sphere.
