The present disclosure proposes a neck massager.

In the embodiment of the present disclosure, please refer to FIGS. 1 to 5 in combination. The neck massager includes a housing 10 and a massage head assembly. The housing 10 has a receiving cavity in which an electric pulse generator (not shown) Out), the massage head assembly includes a connecting piece 20, a mounting seat 30, and a massage electrode 50 arranged on the mounting seat 30. The massage electrode 50 is electrically connected to the electric pulse generator. The connecting piece 20 includes a first connecting section 21 and The second connecting section 22, the first connecting section 21 is connected to the housing 10, the outer circumference of the second connecting section 22 is tapered in the direction away from the housing 10, and the mounting seat 30 is provided with a first relief hole 331 and The first limiting portion 32, the first relief hole 331 and the second connecting section 22 are in clearance fit, and the first limiting portion 32 is connected with the connecting member 20 to restrict the mounting seat 30 from being separated from the connecting member 20.

In one embodiment, the housing 10 includes a middle bracket 11 and clamping arms 12 separately provided at both ends of the middle bracket 11. The middle bracket 11 and the clamping arms 12 together form a receiving cavity, that is, the electric pulse generator can be arranged on the middle bracket 11 or Set on the clamp arm 12. The middle bracket 11 is arranged in an arc-shaped strip, and the ends of the two clamp arms 12 away from the middle bracket 11 are close to each other, so that the neck massager is roughly U-shaped or C-shaped. The middle bracket 11 has an inner side facing the user's neck and a distance away from the user. On the outer side of the neck, the massage head assembly is arranged on the inner side of the middle bracket 11. Specifically, the first connecting section 21 of the connecting member 20 is connected to the inner side of the middle bracket 11, and the massage electrode 50 is arranged on the surface of the mounting seat 30 facing away from the middle bracket 11, that is, on the surface of the mounting seat 30 facing the neck of the user. The number of massage head assemblies can be one or more. When there is one massage head assembly, two massage electrodes 50 are provided on the mounting seat 30. When there are multiple massage head assemblies, each mounting seat 30 can be provided with one massage electrode 50. The number of electrodes 50 and massage head components may specifically be two, three, four, and so on. Of course, in other embodiments, the housing 10 can also be provided with a C-shaped overall structure.

The outer circumferential size of the second connecting section 22 is tapered in the direction away from the first connecting section 21, that is, the distance between the opposite outer circumferential surfaces of the second connecting section 22 gradually decreases in the direction away from the first connecting section 21 For example, the outer peripheral surface of the second connecting section 22 may be a tapered surface, a curved surface, or a spherical surface. The mounting seat 30 is sleeved on the second connecting section 22 through the first giving way hole 331. When the outer circumference of the second connecting section 22 is arranged in a tapered direction away from the housing 10, the first giving way hole 331 can be made The hole diameter is at least larger than the outer diameter of a part of the second connecting section 22 to ensure that the first relief hole 331 can at least be clearance fit with a part of the second connecting section 22. In this way, the mounting seat 30 can move relative to the second connecting section 22 along the radial direction of the first relief hole 331, that is, the massage electrode 50 can be offset by a certain angle relative to the connecting member 20 to the circumference. Therefore, when the user wears the neck massager, the mounting seat 30 and the massage electrode 50 can be adaptively offset relative to the connector 20 according to the neck contours of different users, so that the massage electrode 50 is better attached to the user's neck . It can be understood that when the hole wall on one side of the first relief hole 331 abuts on the outer surface of the second connecting section 22, the second connecting section 22 can restrict the mounting seat 30 from moving in the lateral direction, that is, the first relief The larger the distance between the hole wall of the hole 331 and the second connecting section 22 is, the larger the offset range of the mounting seat 30 is, and the adaptability of the massage electrode 50 is better.

The first limiting portion 32 movably cooperates with the connecting member 20, so that the mounting seat 30 can move relative to the connecting member 20 along the arrangement direction of the first connecting section 21 and the second connecting section 22, so as to ensure that the mounting seat 30 can be relative to the connecting member 20. Offset to the surroundings. The first limiting portion 32 has a first limiting surface (not shown in the figure) facing the side of the massage electrode 50, and the connecting member 20 has a second limiting surface 213 on the side facing away from the massage electrode 50. When the mounting seat 30 is installed In the second connecting section 22, the first limiting surface can be located on the side of the second limiting surface 213 away from the massage electrode 50, so that the mounting seat 30 moves away from the first connecting section 21 relative to the connecting member 20 At this time, the first limiting surface can abut against the second limiting surface 213, thereby restricting the mounting seat 30 from being separated from the connecting member 20. That is, when the first limiting surface and the second limiting surface 213 abut, the distance between the hole wall of the first relief hole 331 and the second connecting section 22 is the largest, and when the hole wall of the first relief hole 331 When abutting against the second connecting section 22, the distance between the first limiting surface and the second limiting surface 213 is the largest. This arrangement can ensure that the mounting seat 30 and the connecting member 20 have a large movable space, which can facilitate the mounting seat 30 The offset movement relative to the second connecting section 22.

In the technical solution of the present disclosure, the outer peripheral dimension of the second connecting section 22 of the connecting member 20 is set to be tapered in the direction away from the housing 10, and when the mounting seat 30 is installed on the connecting member 20, the first part of the mounting seat 30 The positioning hole 331 is in clearance fit with the second connecting section 22, so that the mounting seat 30 can move relative to the second connecting section 22 along the radial direction of the first relief hole 331, that is, the massage electrode 50 can be moved around the connecting member 20 Offset a certain angle. The first limiting portion 32 on the mounting base 30 is connected to the connecting member 20, so that the mounting base 30 can be prevented from being separated from the connecting member 20 when it is ensured that the mounting base 30 can move relative to the connecting member 20.

In one embodiment, the outer peripheral surface of the second connecting section 22 is arranged in a spherical shape. This can ensure that the outer peripheral surface of the second connecting section 22 is relatively smooth, so that the mounting seat 30 moves more smoothly on the first connecting section 21, and is also beneficial to increase the offset angle of the mounting seat 30, so that the massage electrode 50 Can be better adapted to fit the user's neck. Of course, in other embodiments, the outer circumferential surface of the second connecting section 22 may also be arranged in an arc shape along the extending direction of the second connecting section 22.

The limiting portion 32 extends into the second relief hole 23 and is movably connected with the second limiting portion 211 to restrict the first limiting portion 32 from falling off the second relief hole 23.

Specifically, the massage electrode 50 is disposed on the surface of the base 31 facing away from the upper shell 33, a storage cavity is formed between the upper shell 33 and the base 31, and the first relief hole 331 communicates with the storage cavity. The first limiting portion 32 is elongated, the free end of the first limiting portion 32 protrudes from the first relief hole 331, and the first limiting portion 32 is spaced apart from the wall of the first relief hole 331, To ensure that the second connecting section 22 can extend into the first relief hole 331. The second relief hole 23 is provided through the connector 20 along the arrangement direction of the first connection section 21 and the second connection section 22, that is, the second relief hole 23 penetrates the end of the second connection section 22, so that when the second connection When the segment 22 extends into the first relief hole 331, the first limiting portion 32 can also extend into the second relief hole 23.

The hole walls of the first limiting portion 32 and the second relief hole 23 are also arranged at intervals, and the distance between the hole walls of the first limiting portion 32 and the second relief hole 23 is larger than that of the first relief hole 331 The distance between the wall and the second connecting section 22 is to prevent the first limiting portion 32 from abutting against the wall of the second relief hole 23 when the mounting seat 30 moves on the second connecting section 22 to ensure installation The seat 30 can smoothly offset movement relative to the second connecting section 22. The first limiting surface is provided at the end of the first limiting portion 32, the second limiting portion 211 is connected to the wall of the second relief hole 23, and the second limiting surface 213 is provided on the second limiting portion 211.

Specifically, the limiting member 322 is detachably connected to the connecting shaft 321, and the limiting hole 212 penetrates the second limiting portion 211 along the penetrating direction of the first relief hole 331, so that the connecting shaft 321 can protrude from the limiting hole 212 A side of the second limiting portion 211 away from the mounting seat 30, so that the limiting member 322 can be connected to the connecting shaft 321. The outer size of the limiting member 322 is larger than the aperture of the limiting hole 212, that is, the first limiting surface is provided on the limiting member 322. When the hole wall of the first relief hole 331 abuts the second connecting section 22, the limiting The positioning member 322 is spaced from the second limiting portion 211. Such a structure is simple, easy to install, and can ensure the reliability of the connection between the first limiting portion 32 and the second limiting portion 211.

Wherein, the limiting hole 212 may be a straight hole, or the hole diameter of the limiting hole 212 first increases and then decreases along its axis, that is, the hole diameter at the two openings of the limiting hole 212 is larger than the hole diameter at the middle position, so The interference between the edge of the limiting hole 212 and the connecting shaft 321 is reduced. In addition, in an embodiment, the hole wall of the limiting hole 212 includes two oppositely arranged straight sections and two oppositely arranged arc-shaped sections along the circumferential direction. The straight line sections are connected between the two arc-shaped sections, that is, the limiting hole 212 has a waist circle.
