DETAILED DESCRIPTION OF THE INVENTION

[0023] Referring to FIGS. 1 to 4, a roller type vagina contraction ball of the invention is provided and detailed below. The roller type vagina contraction ball comprises a handle 1, where a switch 2 is disposed at a top of the end, away from a housing 3, of the handle 1, and an output end of the switch 2 is electrically connected to an input end of the motor 14.

[0024] During use, the switch 2 is disposed at a top of a rear end of the handle 1, so that the vagina contraction ball is convenient to be turned on and turned off.

[0025] A base 5 is disposed at first end of the handle 1, a bottom end inside the base 5 is disposed with a circuit board 13, a motor 14 is disposed inside the base 5 above the circuit board 13, a battery 11 is disposed at a top of the base 5 above the motor 14, and an output end of the battery 11 is electrically connected to an input end of the circuit board 13.

[0026] During use, the battery 11 is disposed at an upper end of the base 5, so as to perform power supply treatment on the vagina contraction ball.

[0027] An outer surface of the side, away from the reduction gear box 10, of the motor 14 is rotationally connected to an eccentric wheel 12.

[0028] During use, the eccentric wheel 12 is driven to rotate when the motor 14 runs, so that the base 5 and the front cover 9 can vibrate slightly, thereby achieving the purpose of vibrating and stimulating the vagina.

[0029] The end, away from the handle 1, of the motor 14 is provided with a reduction gear box 10; the end, away from the motor 14, of the reduction gear box 10 is provided with a front bearing base 8; equidistant positioning shafts 7 are disposed on an outer surface of the side, away from the reduction gear box 10, of the front bearing base 8; outer surfaces of the positioning shafts 7 are all sleeved with balls 6; four groups of balls 6 are provided, and an angle between the adjacent balls 6 is 90 degrees.

[0030] During use, the balls 6 are set to fit with the protrusions 4, so as to drive the housing 3 to rotate.

[0031] The ends, away from the front bearing base 8, of the balls 6 are provided with a front cover 9, and first end of the front cover 9 is connected to first end of the front bearing base 8.

[0032] The housing 3 is sleeved on an outer surface of the base 5, and an inner surface of the end, away from the base 5, of the housing 3 respectively contacts the front bearing base 8 and the outer surface of the front cover 9.

[0033] Equidistant protrusions 4 are disposed on an outer surface of the side, away from the handle 1, of the housing 3; an angle between the adjacent protrusions 4 is 90 degrees; and inner surfaces of the protrusions 4 contact outer surfaces of one sides of the balls 6.

[0034] During use, the protrusions 4 are equidistantly disposed on the outer surface of the housing 3, so as to enhance frictional force between the housing 3 and the vagina inner surface, thereby improving the stimulating effect of the vagina contraction ball on the vagina.

[0035] During the use of the invention, the motor 14 first drives the front bearing base 8 to rotate slowly through the reduction gear box 10 to make the front bearing base 8 drive the front cover 9 to slowly rotate through the positioning shafts 7 and the balls 6 in turn, so that when rotating, the front cover 9 and the front bearing base 8 drive the housing 3 to rotate slowly through the balls 6, and sensitive areas of the vagina can be rubbed and irritated automatically and in all directions, so as to achieve the purpose of contracting the vagina and exercising the vagina grip strength; afterwards, a plurality of groups of protrusions 4 are equidistantly disposed on the outer surface of the housing 3, and the balls 6 disposed inside the protrusions 4 support and limit the protrusions 4, so as to enhance the frictional force between the housing 3 and the vagina inner surface, thereby further improving the stimulating effect of the vagina contraction ball on the vagina; and finally, the eccentric wheel 12 is driven to rotate when the motor 14 runs, so that the base 5 and the front cover 9 can vibrate slightly, thereby achieving the purpose of vibrating and stimulating the vagina. In addition, the vagina contraction ball may also be used to massage the male prostate, so as to achieve the effect of assisting rehabilitation massage and physiotherapy, thereby completing the use of the vagina contraction ball.

[0036] While the invention has been described in terms of preferred embodiments, those skilled in the art will recognize that the invention can be practiced with modifications within the spirit and scope of the appended claims.
