Description:
BACKGROUND OF THE INVENTION  
       [0001]     1. Field of the Invention  
         [0002]     The present invention relates to a cup structure with surfaces of changeable patterns, and more particularly to a cup structure installed at the periphery of a cup body that utilizes the rotation of a shaft to drive a reel to display a portion of patterns on the periphery of the cup body, so as to attract children&#39;s attention and curiosity and further to give more fun for children to use the cup for drinking water.  
         [0003]     2. Description of the Related Art  
         [0004]     As a cup is an indispensable appliance in our daily life, a cup is always a cup regardless of the material it is made of, and even if a cup body is painted with different figures or pictures, the figures or pictures are still static. Cups of this sort can no longer attract children&#39;s attention after a long time of use and thus will reduce the children&#39;s willingness of drinking water.  
         [0005]     In view of the shortcomings of the foregoing cup structure, some manufacturers have made improvements as disclosed in R.O.C. Application Pat. No. 87211563 (or Publication No. 357587) by providing a light emitting cup structure that comprises a cup body and a base, wherein the cup body is an integral structure having an internal wall, an external wall, and an appropriate gap between the two walls, and the base includes an electroluminescent laminate, a plurality of partitions extended from the bottom of the electroluminescent laminate, and a plurality of containing grooves disposed at the bottom of the base for containing a circuit board, a power supply and a switch electrically connected to the electroluminescent laminate, and a panel is fixed at the bottom of the base and has a through hole corresponding to the power supply, and a detachable cover is installed at the through hole, and the pressing portion of the foregoing switch is protruded from the panel, such that the base can be embedded into the bottom of the cup body, and the electroluminescent laminate on the base is situated precisely in the gap of the cup body to constitute a light emitting cup.  
         [0006]     After a power switch is turned on, sufficient electric power is supplied to the circuit board to control the electroluminescent laminate and further light up the electroluminescent laminate. However, the structure of such cup body must have the internal wall, external wall, and gap between the two walls to install the electroluminescent laminate, and thus the manufacturing procedure is very complicated. Further, the base has to contain the circuit board and power supply, and thus the base has relatively large height and weight, which may create a burden for children to use the cup.  
       SUMMARY OF THE INVENTION  
       [0007]     In view of the shortcomings of the prior art cup structure which is monotonous and boring to use and whose structure is complicated, the inventor of the present invention based on years of experience in the related industry to conduct extensive researches and experiments, and finally invented a cup structure with surfaces of changeable patterns in accordance with the invention.  
         [0008]     Therefore, it is a primary objective of the present invention to provide a cup structure with surfaces of changeable patterns to overcome the shortcomings of the prior art, and the cup structure comprises a cup body, and the cup body comprises an internal wall, an external wall, and a containing space. The containing space includes at least one driving shaft and driven shaft disposed on a side of the containing space, and the driving shaft is engaged with the driven shaft by an axle, and the containing space includes a reel. The length of the reel is much larger than the periphery of the cup body, and the surface of the reel includes various different patterns or a continuous essay. Both ends of the reel are wound around the driving shaft and the driven shaft, such that when the cup is used, the driving shaft and the driven shaft are rotated to change the surrounding portion of the cup body around the reel, and thus the patterns or texts on the reel can be rotated and changed constantly to satisfy the children&#39;s curiosity. Unlike the prior art cup structure having a complicated manufacturing process, the manufacture of the cup structure of the invention is much simpler, and it thus can save manufacturing costs.  
         [0009]     A secondary objective of the present invention is to provide a cup structure with surfaces of changeable patterns, and both ends of the reel are wound around different driving shafts, and these driving shafts keep a specific distance apart, such that when the cup is in use, the two driving shafts are rotated simultaneously, and the reel constantly changes the surrounding portion protruded from the cup body.  
         [0010]     A further objective of the present invention is to provide a cup structure with surfaces of changeable patterns that comprises a transmission wheel disposed between the driving shaft and the driven shaft, so as to provide smooth rotations of the reel.  
         [0011]     Another objective of the present invention is to provide a cup structure with surfaces of changeable patterns, wherein both ends of the reel are wound around different driving shafts, and these driving shafts keep a specific distance apart, and the bottom of the cup includes a drive circuit and a motor, and the motor includes an axle connected to the driving shaft, such that when the cup is in use, the motor is rotated to constantly change the surrounding portion of the reel protruded from the cup body.  
         [0012]     Another further objective of the present invention is to provide a cup structure with surfaces of changeable patterns, and the cup body at its bottom includes a base, and the periphery of the base includes an elastic member, so that when the base is embedded into the containing space, the elasticity of the elastic member fixes the base into its position, so as to achieve the waterproof effect.
