[0030] See appendix Figure 1-37. In an embodiment of this invention, a bidirectional rotary abdominal massager includes an outer ring rotary disc 1, an inner ring rotary disc 4, and a motor. The outer ring rotary disc 1 is provided with outer ring massage heads 2, which are distributed circumferentially along the outer ring rotary disc 1 and are strip-shaped. The outer ring rotary disc 1 has an inner gear ring 3. The inner ring rotary disc 4 is provided with inner ring massage heads 5, which are distributed circumferentially along the inner ring rotary disc 4 and are spaced between large and small. The inner ring massage heads 5 are hemispherical. The inner ring rotary disc 4 is driven by a first gear 6, which has an outer gear ring 7. The first gear 6 is connected to a hexagonal shaft 12, and the inner ring rotary disc 4 is sleeved on the hexagonal shaft 12. The output shaft of the motor is driven by a second gear 9.

[0031] The second gear 9 is coaxially connected to a bidirectional drive member 10, which has a gear ring portion 11 located between the inner gear ring 3 and the outer gear ring 7, and meshes with the inner gear ring 3 and the outer gear ring 7 respectively.

[0032] In this embodiment, specifically, the motor output shaft is a worm gear that meshes with the second gear 9. The teeth of the second gear 9 are inclined, equivalent to a worm wheel (a special helical gear). The rotation of the motor output shaft drives the second gear 9 to rotate, and the bidirectional drive member 10, which is coaxially arranged with the second gear 9, rotates. Through the meshing of the gear ring part 11 with the inner gear ring 3 and the outer gear ring 7, it drives the outer ring turntable 1 and the first gear 6 to rotate. The first gear 6 drives the inner ring turntable 4 to rotate through the hexagonal shaft 12. The outer ring massage head 2 and the inner ring massage head 5 move in opposite directions, performing forward and reverse massage on the human body to improve the massage effect. The circumferential distribution is adapted to the movement trajectory. The strip and hemispherical shapes and the large and small intervals can improve the massage effect of the corresponding massage heads. The inner ring turntable 4 is sleeved on the hexagonal shaft 12 for easy installation. The bidirectional drive member 10 drives the outer ring turntable 1 and the inner ring turntable 4 simultaneously through the gear ring part 11. The transmission structure is simple, with few transmission stages and high efficiency.

[0033] In other alternative implementations, the motor output shaft may engage with a second gear 9 via a gear, but is not limited to this; the motor driving the gear rotation is a well-established technology.

[0034] See appendix Figure 4-68. It also includes an inner shell 13, in which the motor is disposed. The second gear 9 is rotatably disposed within the inner shell 13. The inner shell 13 has a first opening through which the bidirectional drive member 10 passes. The first gear 6 is rotatably disposed on the inner shell 13. The inner shell 13 is provided with an upper cover 14. The first gear 6 is located below the upper cover 14. The upper cover 14 has a second opening through which the hexagonal shaft 12 passes. The outer ring turntable 1 is rotatably disposed on the upper cover 14. The outer ring turntable 1 is equipped with a cover plate 17, which is inserted into the upper cover 14. The upper cover 14 has circumferentially arranged balls 15. The outer ring turntable 1 has a circumferential sliding groove 16 below it, which engages with the balls 15.

[0035] In this embodiment, the inner shell 13 can protect the motor and the second gear 9, and together with the upper cover 14, form a mounting bracket for the outer ring turntable 1 to be installed. The bidirectional drive member 10 drives the outer ring turntable 1 to rotate through the internal gear ring 3. The circumferential groove 16 moves relative to the ball 15. The ball 15 and the circumferential groove 16 cooperate to reduce the coefficient of friction between the outer ring turntable 1 and the upper cover 14. The cover plate 17 covers the outer ring turntable 1 and together with the upper cover 14, limits the upper and lower positioning of the outer ring turntable 1 to ensure the stable rotation of the outer ring turntable 1. On this basis, an outer shell 18 can be set to protect the inner shell 13, the bidirectional drive member 10, the first gear 6 and other structures. Straps 19 are set on both sides of the outer shell 18. The connection method between the straps 19 can be adhesive, magnetic attraction, etc.

[0036] The above description represents the preferred embodiment of this utility model. It should be noted that the protection scope of this utility model is not limited thereto. For those skilled in the art, various improvements, modifications, or equivalent substitutions can be made without departing from the equivalent inventive concept disclosed in this utility model, and these modifications and substitutions are also considered to be within the protection scope of this utility model.
