Abstract: The present disclosure is relates to a TPU ball structure and a manufacturing method thereof. The TPU ball structure includes a ball bladder layer, a yarn layer and a surface layer. The ball bladder layer is made of TPU material. The yarn layer is made of TPU material, and the yarn layer is disposed to cover the ball bladder layer. The surface layer is made of TPU material, and the surface layer is disposed to cover the yarn layer. The above layers of the TPU ball structure are made of TPU material to satisfy a requirement for environmental protection, and are recyclable. There is no need to use adhesive to adhere the above layers of the TPU ball structure. Therefore, the peeling strength between the layers of the TPU ball structure can be increased so that the whole peeling strength of the TPU ball structure can be increased.

Abstract: A glowing golf ball is provided. A mounting hole is mounted in a light permeable ball and a light emitting member is mounted in the mounting hole. The light emitting member consists of a tube, a light emitting cap, a miniature battery, and a tube base. The tube is provided with a mounting room for mounting the light emitting cap. A light source is disposed on the light emitting cap and the miniature battery is fixed on the tube base. When the tube base and the tube are covered and fixed by each other, the miniature battery and the light source of the light emitting cap are electrically connected. Thus the light source emits light for allowing golf players to see flight paths and final landing positions of the golf ball in a more eye-catching way under poor light condition.
