[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0026] A highly stable kneading massage mechanism includes a lower shell 1 and an upper shell 2. The upper shell 2 is fixedly mounted on the top of the lower shell 1 with screws. A motor base 3 is fixedly connected inside the lower shell 1, and a brushless motor 4 is fixedly connected to the motor base 3. A worm gear 5 is fixedly connected to the output shaft of the brushless motor 4. Two rotating seats 6 are also provided inside the lower shell 1. A worm wheel 7 and a first helical gear 8 are rotatably arranged between the two rotating seats 6. The worm wheel 7 and the first helical gear 8 are coaxially fixedly installed. Two bearings 9 are also provided on the lower shell 1. A drive shaft 10 is rotatably arranged between the two bearings 9. A second helical gear 11 that meshes with the first helical gear 8 is fixedly connected to the drive shaft 10. When the worm gear 5 rotates, it can drive the worm wheel 7. The first helical gear 8 rotates, which in turn drives the second helical gear 11 and the transmission shaft 10 to rotate. Through the multi-stage transmission of the gear set, the transmission ratio can be increased, providing a better transmission effect. Both ends of the transmission shaft 10 are connected to the connecting structure 12. A swing arm 13 is provided on one side of each of the two sets of connecting structures 12. A round massage head 14 is connected to one end of each of the two sets of swing arms 13. A large massage head 15 is also connected to the connecting structure 12. Limiting grooves 16 are opened on the opposite sides of the two sets of swing arms 13. Protrusions 17 are fixedly connected to both sides of the upper shell 2. The protrusions 17 can slide freely inside the limiting grooves 16, thereby limiting the movement trajectory of the swing arms 13, making it more stable during massage and improving the use effect of the massage mechanism.

[0027] Furthermore, a mounting base 18 for mounting the round massage head 14 is fixedly connected to one end of the swing arm 13, enabling quick assembly and disassembly of the round massage head 14.

[0028] Furthermore, the connecting structure 12 includes a mounting base 121. An eccentric wheel 122 is connected to one side of the mounting base 121. The eccentric wheel 122 is connected to one end of the drive shaft 10. When the drive shaft 10 drives the eccentric wheel 122 to rotate, it can rotate irregularly. A guide block 123 is connected to the other side of the mounting base 121. A bracket 124 is provided between the guide block 123 and the mounting base 121. When the guide block 123 rotates, it cooperates with the mounting base 121, allowing the bracket 124 to reciprocate and swing, thereby driving the large massage head 15 to start working. The large massage head 15 is detachably connected to the top of the bracket 124.

[0029] Furthermore, the circular massage head 14 includes a positioning seat 141 and a contact part 142. The positioning seat 141 is detachably mounted on the swing arm 13 via a fixing seat 18. The contact part 142 is made of silicone, which provides a good contact effect. A fixing member 143 is provided between the positioning seat 141 and the contact part 142. A positioning block 144 is fixedly connected to the top of the contact part 142. Multiple snap-fit ​​blocks 145 are fixedly connected to the fixing member 143. The multiple snap-fit ​​blocks 145 can snap into the slots inside the positioning block 144, thereby enabling quick disassembly and assembly of the contact part 142 for easy later maintenance. Multiple buckles 146 are also fixedly connected to the fixing member 143. A snap-fit ​​groove for snap-fitting the buckles 146 is provided inside the positioning seat 141 to realize the snap-fit ​​installation of the fixing member 143.

[0030] Furthermore, the large massage head 15 includes an inner shell 151 and an outer shell 154. The outer shell 154 is made of transparent material, which can provide a certain light transmission effect. The outer shell 154 can be fixedly installed on the inner shell 151 by screws. A locking seat 152 is fixedly connected to the bottom of the inner shell 151. The locking seat 152 is compatible with the bracket 124, which allows the large massage head 15 to be installed quickly. Two sets of LED light sources 153 are set inside the inner shell 151, which can provide some illumination in places where the light is not bright enough. At the same time, they can generate some light and heat during operation to enhance the massage effect.

[0031] The implementation principle of this embodiment is as follows: the brushless motor 4 drives the worm gear 5 to drive the worm wheel 7 to rotate coaxially with the first helical gear 8, and transmits the power to the transmission shaft 10 through the second helical gear 11. The eccentric wheel 122 converts the rotational motion into reciprocating oscillation, and drives the bracket 124 to drive the large massage head 15 to perform kneading motion. At the same time, the round massage head 14 at the end of the swing arm 13 maintains a stable trajectory under the constraint of the limiting groove 16 and the protrusion 17.
