DETAILED DESCRIPTION OF THE INVENTION

[0019] Referring to FIGS. 1 to 4, the invention provides a reciprocating rotary masturbation cup, which comprises a housing 2 including an upper shell 20A and a lower shell 20B which are fixedly installed to protect the internal transmission components, a push-button 1 is fixedly installed on the top of the upper shell 20A, a direct current (DC) motor 7 is installed inside the upper shell 20A, the DC motor 7 includes an upper cover 3 of the DC motor 7 and a lower cover 13 of the DC motor 7. The DC motor 7 is fixedly installed between the upper cover 3 of the DC motor 7 and the lower cover 13 of the DC motor 7 through screws.

[0020] A sealing ring 4 is bonded between the upper cover 3 of the DC motor 7 and the lower cover 13 of the DC motor 7 to ensure the safety of the internal parts between the upper cover 3 of the DC motor 7 and the lower cover 13 of the DC motor 7 and prevent water from affecting its work. The lower cover 13 of the DC motor 7 is fixed with a motor fastener 5 at one side of the DC motor 7. The motor fastener 5 is sleeved at the output end of the DC motor 7 and is adapted to prevent it from shaking inside.

[0021] A circuit board 11 and a battery 12 are arranged internally between the upper cover 3 of the DC motor 7 and the lower cover 13 of the DC motor 7. The circuit board 11 is electrically connected to the battery 12. The push-button 1 is electrically connected to the circuit board 11. The circuit board 11 is electrically connected to the DC motor 7. The output end of the DC motor 7 is provided with a transmission gear 6. The bottom of the lower cover 3 of the DC motor 7 is provided with a roller fastening member 16. The lower cover 13 of the DC motor 7 is fixed on the outside of the roller fastening member 16 through screws.

[0022] The top of the lower shell 20B is provided with a component which is convenient for reciprocation and rotation. The component is a reciprocating roller 15, which is movably installed on the inner surface of the roller fastening member 16. The outer surface of the reciprocating roller 15 is provided with a curved groove 151, and the roller fastening member 16 is fixed with a pin 14 which is located in the curved groove 151. The reciprocating roller 15 is movably installed on the inner surface of the roller fastening member 16 through the pin 14.

[0023] A grooved gear 9 is sleeved on a forward end of the reciprocating roller 15 and secured thereto, and the grooved gear 9 and the transmission gear 6 are engaged with each other. A reciprocating silicone massage sleeve 8 is secured to an inner surface of the reciprocating roller 15. The reciprocating silicone massage sleeve 8 is composed of a silicone cylinder and a convex head. A plurality of spaced lengthwise ridges 152 are formed on the outer surface of the reciprocating roller 15.

[0024] The lengthwise ridges 152 are movably secured to the grooved gear 9, and the grooved gear 9 is movably limited on the lower cover 13 of the DC motor reduction. In this embodiment, the rotation of the transmission gear 6 drives the rotation of the grooved gear 9, and the grooved gear 9 drives the rotation of the lengthwise ridges 152 and the reciprocating roller 15. With the cooperation of the curved groove 151 and the pin 14, the reciprocating roller 15 realizes reciprocation and rotation at the same time.

[0025] In actual use, press the push-button 1 to start the DC motor 7. The output end of the DC motor 7 rotates to drive the transmission gear 6. At this time, the rotation of the transmission gear 6 drives the rotation of the grooved gear 9, and the grooved gear 9 drives the rotation of the lengthwise ridges 152 and the reciprocating roller 15. With the cooperation of the curved groove 151 and the pin 14, the reciprocating roller 15 realizes reciprocation and rotation at the same time, and the reciprocating silicone massage sleeve 8 also realizes reciprocation and rotation at the same time, which makes the user more relaxed and stimulated. The overall reciprocation and rotation of the masturbation cup saves product space, with simple structure and large torque.

[0026] 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.
