For the purpose of explaining the technical solution of the present invention, the implementation of the massage device provided in the present invention will be described in detail below with reference to specific drawings.

As shown in FIG. 1-2, in an embodiment of the present invention, the neck massage device is exemplified to describe the construction of the massage device. It should be understood that the construction of the massage device is not limited to the neck massage device. In particular, the neck massage device comprises a body 10, two massage head assemblies 20 extending from the body 10 and located oppositely, and a drive assembly 30 located in the body 10 for driving two massage head assemblies 20. The two massage head assemblies 20 mutually oscillate under the action of the drive assembly 30, creating kneading massage movements. When the two massage head assemblies 20 vibrate towards each other, the inner side 26 of each massage head assembly 20 adjacent to the other massage head assembly 20 forms an angle α with the surface of the body 10, and the angle α is in the range α≤54 °. When the two massage head assemblies 20 deviate from each other, the outer side 25 of each massage head assembly 20, distant from the other massage head assembly 20, forms an angle β with the surface of the body 10, and the angle β is in the range β ≥ 23 °.

In this embodiment, since the massage head assembly 20 oscillates mutually under the action of the drive assembly 30, during operation, the two massage head assemblies 20 are closer together or further apart, the inner side 26 and the outer side 25 of each massage head assembly 20, respectively form an angle with the housing 10. As shown in FIG. 1, when the two massage head assemblies 20 move towards each other, the angle α between the inner side 26 of the massage head assembly and the surface of the body 10 is the smallest, and if the minimum α value is in the range α ≤ 54 °, the angle α is too small to reach the finger, therefore, the finger will not be pinched, and the angle between the outer side 25 of the massage head assembly and the surface of the body 10 is the largest, so there is no pinching problem. When the two massage head assemblies 20 move apart, the angle β between the surface 25 of the outer side of the massage head assembly 20 and the surface of the body 10 is the smallest, and if the minimum β value is in the range β ≥ 23 °, the gap between the outer side 25 and the body 10 is sufficient large, and even if the finger is inserted, the finger will not be pinched, whereby the pinching problem of the fingers is substantially prevented during operation.

In addition, when the two massage head assemblies 20 oscillate towards each other as shown in FIG. 1, the height H1 is the distance from the lowest point of the inner side surface 26 of each massage head assembly 20 adjacent to the other massage head assembly 20 to the highest point of the surface of the body 10, and the height H1 is in the range H1 ≤ 10 mm. The smaller the H1, the better, that is, the smaller the gap between the inner side 26 and the surface of the housing 10, the less likely it is to get fingers caught, thereby preventing pinching of the fingers. When the two massage head assemblies 20 deviate from each other, the height H2 is the distance from the lowest point of the outer side 25 of each massage head assembly 20, distant from the other massage head assembly 20, to the highest point of the surface of the body 10, and the height H2 is in the range H2 ≥ 15 mm. The larger the H2, the better, that is, the larger the gap between the outer side 25 of the massage head assembly and the surface of the body 10, even if the finger is inserted, the finger will not be pinched.

In particular with regard to FIG. 3 and FIG. 4, the drive unit 30 comprises a drive motor 31 and an eccentric wheel assembly 32 driven by the drive motor 31 and capable of vibrating the massage head assembly 20. The housing 10 is provided with guide seats 11, which are located on both sides of the eccentric wheel assembly 32, respectively. Each guide seat 11 is provided with a guide groove 12 that opens towards the eccentric wheel assembly 32. A locating pin 13 is respectively provided on both sides of the eccentric wheel assembly 32, which can pass into the guide grooves 12 and can slide in the guide groove 12. Thus, the reciprocating swing of the eccentric wheel assembly 32 is smoother when the positioning pin 13 is positioned with the guide groove 12, so that the vibration of the massage head assembly 20 becomes smoother and the massage head experience is improved.

Specifically, the eccentric wheel assembly 32 has an eccentric wheel housing 321 located on the outside and two pad bodies 322. Two pad bodies 322 are respectively disposed on the inner side and the outer side of the eccentric wheel body 321 along the eccentric wheel axial direction. Two locating pins 13 are located on both sides of the eccentric wheel housing 321. In this embodiment, the structure and principle of the eccentric wheel assembly 32 for moving the massage head assembly 20 using the eccentric structure is the same as the previous massage device and is not shown in detail herein.

In addition, the drive assembly 30 further comprises a transmission assembly and a transmission shaft 33. The transmission assembly includes a first gear 34 driven by a drive motor 31 and a second gear 35 meshing with the first gear 34. Two eccentric gear assemblies 32 are respectively disposed at both ends of the transmission shaft 33, the second gear 35 is fitted on the transmission shaft 33 and is located on the inner side of one of the eccentric wheels 32.

Thus, the finger is prevented from being pinched when it enters the gap during massage. In addition, the auxiliary pad 40 can move with the massage head assembly 20 without affecting the massage movements of the massage head assembly 20.

In particular, a portion of the body 10 at the edge of the fastening hole 14 is convex upward, having a first spherical shape, and the auxiliary strip 40 is convex upward, having a second spherical shape, and the center of the first spherical surface 15 coincides with the center of the second spherical surface 41. Since the center of the first of the spherical surface 15 coincides with the center of the second spherical surface 41, the second spherical auxiliary pad 40 can close the gap when moved at any angle together with the massage head assembly 20, thereby preventing the insertion of fingers and ensuring safety.

The massage head assembly 20 comprises a drive arm 21 connected to the drive assembly 30, a massage head holder 22 attached to the drive arm 21, and a massage head 23 disposed on the massage head holder 22. The auxiliary strip 40 has a through hole 42 in the middle, and a drive bracket 21 is located in the through hole 42, and the outer edge of the auxiliary strip 40 extends into the inner side of the fastening hole 14. Thus, the outer edge of the auxiliary strip 40 extends into the inner side of the fastening hole 14, that is, the auxiliary pad 40 is bounded by the mounting hole 14 and moves with the massage head holder 22 in the range of the mounting hole 14.

In addition, a soft rubber pad 50 is disposed in the attachment hole 14, and an alignment ring 60 is disposed in the hole of the soft rubber 50, and the massage head assembly 20 passes through the soft rubber pad 50 and an alignment ring 60. When the massage head assembly 20 comes out of the attachment hole 14, a soft rubber pad 50 is arranged on the fastening hole 14, and the fastening hole 14 is blocked by a soft rubber pad 50. Thus, on the one hand, the finger is prevented from being pinched when it enters the fastening hole 14, on the other hand, this makes the fastening hole 14 more beautiful ... In addition, when the massage head assembly 20 passes through the soft rubber pad 50, the soft rubber pad 50 stretches to generate noise as the massage head assembly 20 moves, the locating ring 60 located here functions to attach the soft rubber pad 50 to reduce the tension range of the soft rubber pad 50 and further reduce noise, thereby providing the user with a better massage experience. Meanwhile, the soft rubber pad 50 is also protected from wear by attaching the locating ring 60.

In particular, the soft rubber pad 50 can be corrugated to form a collar 51, and the locating ring 60 is attached to the collar 51. The locating ring 60 located on the collar 51 presses against the soft rubber 50.

In this embodiment, the body 10 is covered with a silicone shield 70, and the soft rubber pad 50 is integrally formed with the silicone shield 70. During massage, the silicone shield 70 may come into contact with the neck, and the integral silicone shield 70 is located outside housing 10 to facilitate cleaning of the silicone protective casing 70 without damaging the housing 10.
