Detailed implementation manners

[0028] For better understanding and implementation, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0029] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model.

[0031] Refer to Figures 1-7 , an embodiment of the present utility model discloses a neck massage device. The neck massage device includes a motor 1, and an output shaft 11 is provided on the motor 1; the neck massage device further includes a main shaft 2, and the main shaft 2 is connected to the output shaft 11 of the motor 1; the neck massage device further includes at least one massage head 3, which is provided with a swing arm shaft 31, and the swing arm shaft 31 is connected to the main shaft 2. Let the plane where the main shaft 2 and the swing arm shaft 31 are located together be the first plane, and the output shaft 11 of the motor 1 is inclined relative to the first plane, and let the inclination angle between the output shaft 11 of the motor 1 and the first plane be α.

[0032] Among them, in view of the fact that the existing neck massagers have an insufficiently compact internal movement structure. For example, the output shaft 11 of the motor 1 is horizontally arranged, resulting in a relatively large volume of the entire massager. Therefore, the motor 1 in this neck massage device is inclined, which can make the overall structure more compact and can well control the volume of the entire neck massage device. Moreover, if a larger battery can be accommodated within the same movement volume, the usage time of this neck massage device can be extended.

[0033] In an optional embodiment, the range of the inclination angle α is: 5° ≤ α ≤ 60°.

[0034] Among them, the inclination angle α can specifically be 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, etc. In other embodiments, the range of the inclination angle α can also be other values within 5° ≤ α ≤ 60°.

[0035] In an optional embodiment, a first transmission component is arranged between the output shaft 11 of the motor 1 and the main shaft 2. The first transmission component includes a worm 41 and a worm gear 42 meshing with the worm 41. The worm 41 is arranged on the output shaft 11 of the motor 1, and the worm gear 42 is arranged on the main shaft 2.

[0036] Among them, the output shaft 11 of the motor 1 drives the worm 41 to rotate, the worm 41 drives the worm gear 42 to rotate, the worm gear 42 drives the main shaft 2 to rotate, and the main shaft 2 drives the massage head 3 to work through the swing arm shaft 31. With such an arrangement, the rotation speed of the motor 1 is specifically reduced to the required rotation speed through the worm and worm gear 41 mechanism to prevent the rotation speed of the main shaft 2 from being too high, which may cause the massage frequency of the massage head 3 to be too high, thereby improving the comfort of the user.

[0037] In an optional embodiment, let the horizontal plane where the main shaft 2 is located be the second plane, and the axis of the projection of the output shaft 11 of the motor 1 on the second plane is perpendicular to the main shaft 2.

[0038] Among them, the relationship between the output shaft 11 of the motor 1 and the main shaft 2 is that the axis of the projection of the output shaft 11 of the motor on the second plane is perpendicular to the main shaft 2, which can further make the overall structure more compact and can well control the volume of the entire neck massage device.

[0039] In an optional embodiment, a second transmission component is arranged between the worm gear 42 and the main shaft 2. The second transmission component includes a first gear 43, a second gear 44, and a connecting column 45. One end of the connecting column 45 is fixedly connected to the worm gear 42 and the other end is fixedly connected to the first gear 43. The first gear 43 and the second gear 44 are meshed, the second gear 44 is fixedly connected to the main shaft 2, and the diameter of the first gear 43 is smaller than the diameter of the second gear 44.

[0040] Among them, the output shaft 11 of the motor 1 drives the worm 41 to rotate, the worm 41 drives the worm wheel 42 to rotate, the worm wheel 42 drives the first gear 43 to rotate through the connecting column 45, the first gear 43 drives the second gear 44 to rotate, the second gear 44 drives the main shaft 2 to rotate, and the main shaft 2 drives the massage head 3 to work through the swing arm shaft 31. And the first gear 43 is smaller than the second gear 44, which can achieve the effect of deceleration. With such a setting, in addition to the worm and worm wheel 41 mechanism as a deceleration structure, a deceleration structure of the first gear 43 and the second gear 44 is also set, further decelerating the motor 1, further preventing the rotation speed of the main shaft 2 from being too large and causing the massage frequency of the massage head 3 to be too high, and improving the comfort of the user.

[0041] In an optional embodiment, the end of the motor 1 away from the output shaft 11 is set as the tail end, and the tail end of the motor 1 is inclined and close to the massage head 3.

[0042] Among them, the inclination direction of the motor 1 is specifically that the tail end of the motor 1 is inclined downward, and the tail end of the motor 1 is closer to the massage head 3, which can not only make the overall structure more compact, but also make the overall center of gravity lower, and it is more difficult to fall off the user's neck.

[0043] In an optional embodiment, a biasing block 5 is fixed on the main shaft 2, the central axis of the biasing block 5 is inclined to the axis of the main shaft 2, and the swing arm shaft 31 includes a limiting block 311 rotatably connected to the biasing block 5 and a connecting block 312 arranged between the limiting block 311 and the massage head 3; a biasing groove 6 is recessed on the outer circumference of the biasing block 5, and a limiting ring section 313 engaged with the biasing groove 6 is arranged on the limiting block 311, and the limiting ring section 313 is rotatably connected in the biasing groove 6.

[0044] Among them, the output shaft 11 of the motor 1 drives the worm 41 to rotate, the worm 41 drives the worm wheel 42 to rotate, the worm wheel 42 drives the first gear 43 to rotate through the connecting column 45, the first gear 43 drives the second gear 44 to rotate, the second gear 44 drives the main shaft 2 to rotate, and the main shaft 2 actively drives the biasing block 5 to rotate. Since the limiting block 311 on the swing arm shaft 31 and the biasing block 5 are rotatably connected, this means that the swing arm shaft 31 will drive the massage head 3 to reciprocate in this first plane to massage the user's neck. It should be noted that the movement of the massage head 3 can be decomposed into a compound movement of a reciprocating swing in the first plane combined with another reciprocating rotation centered on the swing arm shaft 31.

[0045] To more clearly describe the combined movement of the massage head 3, it is specifically described in conjunction with the accompanying drawings. The reciprocating swing of the massage head 3 in the first plane can be referred to Figure 4 wherein the massage head 3 can specifically reciprocate in the first plane with the intersection point of the axis A of the main shaft 2 and the axis B of the swing arm shaft 31 as the center.

[0046] Moreover, the reciprocating rotation of the massage head 3 centered on the swing arm shaft 31 can be referred to Figure 5 , wherein the massage head 3 can specifically perform reciprocating rotation centered on the axis B of the swing arm shaft 31.

[0047] In an optional embodiment, a sliding bearing is provided between the deflection groove 6 and the limiting ring section 313.

[0048] Wherein, by providing a sliding bearing between the deflection groove 6 and the limiting ring section 313, the rotational smoothness of the limiting block 311 and the deflection block 5 on the swing arm shaft 31 can be improved, thereby improving the overall massage smoothness.

[0049] In an optional embodiment, the deflection block 5 includes a first shaft section 51 and a second shaft section 52. A connecting shaft section 53 is provided on one side of the first shaft section 51 facing the second shaft section 52, and the second shaft section 52 is detachably connected to the connecting shaft section 53; the diameter of the connecting shaft section 53 is smaller than the diameter of the first shaft section 51 to form a deflection groove 6 between the first shaft section 51 and the second shaft section 52.

[0050] Wherein, by providing the detachable first shaft section 51 and second shaft section 52, it is convenient to assemble the limiting ring section 313 of the limiting block 311 on the swing arm shaft 31 into the deflection groove 6 of the deflection block 5, reducing the assembly difficulty and improving the assembly efficiency.

[0051] In an optional embodiment, the first shaft section 51 and the connecting shaft section 53 are integrally formed.

[0052] Wherein, by providing the integrally formed first shaft section 51 and connecting shaft section 53, the structure is simple, convenient for manufacturing and production, reducing the manufacturing difficulty; moreover, the structural strength can also be enhanced to a certain extent.

[0053] The technical means disclosed in the solution of the present utility model are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present utility model.
