The side wall of the inner shell 41 is recessed relative to the position of the tapping limiting hole 611 to form a groove 612. The bottom of the groove 612 is arc-shaped. The tapping limiting hole 611 is located at the center of the bottom of the groove 612. The swing limiting hole 621 is arranged along the axis of the inner shell 41 and is located at the top of the inner shell 41.
[0029] Reference Figure 1 , Figure 2 and Figure 6 The silicone part 11 includes a silicone sleeve 2 and a silicone bottom shell 1. The bottom of the silicone sleeve 2 is hollowed out and covers the massage end and hand-held end of the inner shell 41. The massage end of the silicone sleeve 2 has three elastic parts.

The position of the swing connection part 221 corresponds to the position of the swing limiting hole 621. A swing groove 22 is provided on the outer wall of the silicone sleeve 2 opposite to the position of the swing connection part 221. A swing bar 23 is vertically provided in the swing groove 22. The top of the swing bar 23 extends outside the swing groove 22 (the height of the swing bar 23 is greater than the depth of the swing groove 22). The swing connection part 221 is along the inner shell 41. The axial setting of the inner shell 41 and the reciprocating swing of the pull rod 6 with the periodic eccentric movement of the pull rod 6, thereby driving the swing bar 23 to swing. The position of the striking connection part 24 corresponds to the position of the striking limiting hole 611 and the groove 612. The striking connection part 24 is set radially along the inner shell 41 and reciprocates with the periodic eccentric movement of the pull rod 6. The position of the air flow connection part 211 corresponds to the position of the air flow limiting hole 631. An air flow groove 21 is provided on the outer wall of the silicone sleeve 2 relative to the position of the air flow connection part 211. The air flow connection part 211 is set radially along the inner shell 41 and reciprocates with the periodic eccentric movement of the pull rod 6. The top of the silicone bottom shell 1 is hollowed out. The silicone bottom shell 1 covers the bottom of the inner shell 41 and is connected to the silicone sleeve 2.
[0030] Reference Figure 1 and Figure 2The inner shell 41 houses a drive source, a battery 9, a control board 7, and a charging board 8. The drive source is specifically a motor 5. The motor 5 and the battery 9 are arranged from top to bottom inside the handle end of the inner shell 41. The battery 9 is located between two baffles 31 in the inner shell 41. The control board 7 and the charging board 8 are respectively secured to the opposing inner walls of the inner shell 41. Two buttons 71 on the control board 7 are exposed on the silicone part 11, and two magnetic charging contacts 81 on the charging board 8 are exposed on the silicone part 11. The control board 7, the two buttons 71, the charging board 8, the two magnetic charging contacts 81, and the motor 5 are all electrically connected to the battery 9. The motor 5 is located between the battery 9 and the pull rod 6. The output shaft of the motor 5 is provided with a semi-circular eccentric hammer 51 and an L-shaped eccentric shaft 52. The eccentric hammer 51 is located between the motor 5 and the eccentric shaft 52. In order to make the entire massage device vibrate with the operation of motor 5, eccentric shaft 52 is rotatably connected to pull rod 6 through bearing 53. Pull rod 6 is T-shaped and its three branch ends are respectively connected to the elastic deformation part of silicone part 11 at the corresponding limiting hole position through connectors. In this utility model, the three connectors are specifically a striking connector 61, a swing connector 62 and an air flow connector 63. The striking connector 61, the swing connector 62 and the air flow connector 63 are respectively located at the three branch ends of pull rod 6 and are integrally formed with pull rod 6. The striking connector 61 is inserted into the striking connection part 24, the swing connector 62 is inserted into the swing connection part 221, and the air flow connector 63 is inserted into the air flow connector 63, so that the three branch ends of pull rod 6 are connected one-to-one with the three elastic parts on silicone sleeve 2.
[0031] Reference Figures 1 to 6 The working principle of the eccentric drive massage device of this utility model is as follows:
[0032] Motor 5 drives eccentric hammer 51 and eccentric shaft 52 to rotate together. Since the three branches of pull rod 6 are connected to the three elastic parts on silicone part 11, pull rod 6 cannot rotate and can only move around the circumference of eccentric shaft 52, making oscillating movements in a certain range. On the one hand, the branch end at the top of pull rod 6 drives the oscillating connecting part 221 to oscillate, thereby driving the oscillating bar 23 to oscillate and massage synchronously. On the other hand, the branch end on the left side of pull rod 6 drives the airflow connecting part 211 to reciprocate (similar to the oscillation of the diaphragm pump) to massage. During the oscillation, the airflow connecting part 211 drives the volume of the airflow groove 21 to change continuously, forming an airflow movement. On the other hand, the branch end on the right side of pull rod 6 drives the striking connecting part 24 to move. During its movement, the striking connecting part 24 continuously pulls the corresponding elastic part, forming an outward cyclical striking massage.
[0033] This invention's eccentrically driven massage device offers a gentler, more even, and deeper massage experience compared to existing massage devices. The elastic deformation of the silicone component 11 simulates the pressing and releasing motions of a human hand, precisely targeting acupoints, muscle groups, or other areas to effectively promote blood circulation and relieve muscle tension and pain. Furthermore, due to the excellent elasticity and adaptability of the silicone material, this device is suitable for users of different body types and massage needs, providing a personalized massage experience.
[0034] In summary, this utility model's eccentrically driven massage device, through its unique eccentric driving mechanism and perfect combination with silicone material, achieves an innovative upgrade to traditional massage methods, bringing a brand-new massage experience to the modern health and wellness field.
[0035] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of protection of the present utility model. Therefore, any equivalent changes made in accordance with the scope of the patent application of the present utility model shall still fall within the scope of the present utility model.
