Title: Roller type vagina contraction ball

Description:
FIELD OF THE INVENTION 
     The invention relates to vagina contraction balls and more particularly to a roller type vagina contraction ball. 
     BACKGROUND OF THE INVENTION 
     A vagina contraction ball is typically known as a vagina dumbbell or a vagina yoga ball, which is placed into the female vagina for exercise, so as to enhance the sensibility and flexibility of the vagina inner surface, female sphincter and pelvic floor muscle, making an instantaneous induction like a mimosa, and then the relaxation of the vagina inner surface muscle speeds up the pleasure of orgasm. With the rapid development of science and technology, the type of the vagina contraction ball is increased day by day, and therefore a corresponding roller type vagina contraction ball has been derived. 
     The existing vagina contraction ball can meet the needs of users well, and is mainly provided with a handle, a front end head, a silicone case and other components. Specifically, the front end head is disposed at a front end of the handle, and the case is sleeved on an outer surface of the front end head, so as to combine and form the vagina contraction ball for users to use. According to the above description, although the vagina contraction ball can meet the needs of users to achieve the purpose of exercising and contracting the vagina, the vagina contraction ball is usually inconvenient to exercise and contract the vagina of the user in all directions, and manual operation of users is required to achieve the purpose of exercising and contracting the vagina in all directions, resulting in affecting the contracting effect of the vagina contraction ball on the vaginas of the users, and troubling the users frequently. 
     Thus, the need for improvement still exists. 
     SUMMARY OF THE INVENTION 
     Therefore the purpose of the invention is to provide a roller type vagina contraction ball, so as to solve the following problems: although the vagina contraction ball proposed in the above background can meet the needs of users to achieve the purpose of exercising and contracting the vagina, the vagina contraction ball is usually inconvenient to exercise and contract vaginas of the users in all directions, and manual operation of users is required to achieve the purpose of exercising and contracting the vagina in all directions, resulting in affecting the contracting effect of the vagina contraction ball on the vaginas of the users. 
     In order to implement the above purpose, the invention provides the following technical solution: a roller type vagina contraction ball, including a handle, where a base is disposed at first end of the handle; a bottom end inside the base is disposed with a circuit board; a motor is disposed inside the base above the circuit board; the end, away from the handle, of the motor is provided with a reduction gear box; the end, away from the motor, of the reduction gear box is provided with a front bearing base; equidistant positioning shafts are disposed on an outer surface of one side, away from the reduction gear box, of the front bearing base; outer surfaces of the positioning shafts are all sleeved with balls; the ends, away from the front bearing base, of the balls are provided with a front cover; first end of the front cover is connected to first end of the front bearing base; a case is sleeved on an outer surface of the base, and an inner surface of the end, away from the base, of the case respectively contacts the front bearing base and an outer surface of the front cover. 
     Preferably, a switch is disposed at a top of the end, away from the case, of the handle, and an output end of the switch is electrically connected to an input end of the motor. The switch is disposed at a top of a rear end of the handle, so that the vagina contraction ball is convenient to be turned on and turned off. 
     Preferably, equidistant protrusions are disposed on an outer surface of the side, away from the handle, of the case; an angle between the adjacent protrusions is 90 degrees; and inner surfaces of the protrusions contact outer surfaces of one sides of the balls. The protrusions are equidistantly disposed on the outer surface of the case, so as to enhance frictional force between the case and the vagina inner surface, thereby improving the stimulation effect of the vagina contraction ball on the vagina. 
     Preferably, four groups of balls are provided, and an angle between the adjacent balls is 90 degrees. The balls are set to fit with the protrusions, so as to drive the case to rotate. 
     Preferably, a battery is disposed at a top of the base above the motor, and an output end of the battery is electrically connected to an input end of the circuit board. The battery is disposed at an upper end of the base, so as to perform power supply treatment on the vagina contraction ball. 
     Preferably, an outer surface of the side, away from the reduction gear box, of the motor is rotationally connected to an eccentric wheel. The eccentric wheel is driven to rotate when the motor runs, so that the base and the front cover can vibrate slightly, thereby achieving the purpose of vibrating and stimulating the vagina. 
     The invention has the following advantages and benefits in comparison with the conventional art: 
     The roller type vagina contraction ball can not only rub and irritate sensitive areas of the vagina automatically and in all directions to achieve the effect of contracting the vagina and exercising the vagina grip strength, thereby improving the vagina contracting effect when the vagina contraction ball is used; but also enhance the frictional force between the case and the vagina inner surface to further improve the stimulating effect of the vagina contraction ball on the vagina, thereby achieving the purpose of vibrating and stimulating the vagina. 
     The motor drives the front bearing base to rotate slowly through the reduction gear box to make the front bearing base drive the front cover to slowly rotate through the positioning shafts and the balls in turn, so that when rotating, the front cover and the front bearing base drive the case to rotate slowly through the balls, and sensitive areas of the vagina can be rubbed and irritated automatically and in all directions, so as to achieve the effect of contracting the vagina and exercising the vagina grip strength, thereby improving the vagina contracting effect when the vagina contraction ball is used. 
     A plurality of protrusions are equidistantly disposed on the outer surface of the case, and the balls are disposed inside the protrusions for supporting and limiting the protrusions, so as to enhance the frictional force between the case and the vagina inner surface, thereby further improving the stimulating effect of the vagina contraction ball on the vagina. 
     The eccentric wheel is driven to rotate when the motor runs, so that the base and the front cover can vibrate slightly, thereby achieving the purpose of vibrating and stimulating the vagina. 
     The above and other objects, features and advantages of the invention will become apparent from the following detailed description taken with the accompanying drawings
