The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0028] The present invention is described in detail below in conjunction with the embodiments shown in the accompanying drawings:

[0029] like Figure 1-4As shown, in this embodiment, a cervical eccentric massage device is provided, including an outer shell 12, in which a driving assembly, a massage piece and a pair of symmetrically arranged transmission assemblies are arranged, and the transmission assembly is transmission-connected with the driving assembly to control the movement of the massage piece. The massage piece includes a pair of offset rotary blocks 3 symmetrically arranged in the outer shell 12, and the offset rotary blocks 3 are provided with inclined surfaces, and specifically, half of the surfaces are provided with a bulge toward the outside, and a massage connecting rod 2 is fixedly provided on the inclined surface, that is, the massage connecting rod 2 is fixedly connected to the above-mentioned inclined surface, so that the massage connecting rod 2 extends obliquely outward, and the massage connecting rod 2 is fixedly connected to the above-mentioned inclined surface. The massage connecting rod 2 is integrally formed with a massage head 1. Specifically, the massage connecting rod 2 and the massage head 1 are integrally formed. In the early stage of production, the fluctuation amplitude of the two ends of the massage head 1 against the surface of the human neck and back is preset according to the direction of the massage head to be pressed, and the offset angle is measured in advance. The offset position is described below. The materials used for the massage head 1 supported by the integral molding are consistent. The material can be selected to use flexible materials such as TPU or TPE to improve the comfort of the utility model. Even if it is old and worn, it will not cause the user's skin to be worn. The massage head 1 is a structure that is thick at both ends and thin in the middle. Specifically, the massage head 1 includes a knocking part that extends symmetrically to both ends. The thicker sides are the above-mentioned knocking parts, which are in direct contact with the user. An inclination angle is set between the offset rotary block 3 and the massage connecting rod 2, and this inclination angle is less than 90°; and an inclination angle is also set between the massage head 1 and the massage connecting rod 2, and the angle between the two is also less than 90°. The purpose of the tilt is to convert the rotational action into the alternating swing of the striking part; to strike and press the user's cervical vertebra; and the striking parts on both sides of the massage head 1 can press up and down, front and back, left and right under the movement of the driven output gear 7, and the striking parts on the upper and lower sides of the massage head 1 can alternately move back and forth to press. The offset rotary block includes an eccentric groove with an inward depression at the bottom, and the output transmission assembly includes a driven output gear, and the driven output gear is provided with an eccentric column corresponding to the eccentric groove. In this embodiment, a plurality of protrusions extending upward and distributed in a circular array are also provided in the middle of the driven output gear, and a plurality of grooves distributed in a circular array and recessed inward are also provided at the bottom of the offset rotary block, and the protrusions can be correspondingly engaged with the above-mentioned grooves to control the rotation of the offset rotary block.

[0030] The advantage of this setting is that it can give the massage head more angles to fit the neck and back muscles more closely during exercise, making the massage angle more suitable for the back and neck curves of the human body, thereby enhancing the massage effect.

[0031] In this embodiment, in order to further enable the massage head 1 to accurately press the muscles near the cervical spine, an inwardly inclined structure is provided at the connection between the massage rod 2 and the massage head 1, that is, one end of the massage rod 2 is integrally formed and bent inwardly, so that the above-mentioned pair of massage heads 1 are biased toward the middle. The inwardly inclined structure is used to make the massage surfaces of the pair of massage heads 1 face the middle of one side of the outer shell 12.

[0032] To further explain, in order to avoid excessive pressing, that is, to prevent the offset rotary block 3 from not slowing down and stopping in time, and excessively pressing the muscles of the user, a limiting column 4 is integrally formed and extended outward from the offset rotary block 3. Because the offset rotary block 3 is constantly rotating in a forward and reverse direction under the control of the motor 10, a limiting groove 5 is recessed on the inner wall of the outer shell 12, and the limiting column 4 extends into the limiting groove 5. The width of the limiting column 4 is smaller than the width of the limiting groove 5, and the outer shell 12 limits the swing range of the offset rotary block 3 through the limiting groove 5. The range in which the offset rotary block 3 can move depends on the width of the limiting groove 5. When the offset rotary block 3 is swung into place, the limiting groove 5 will further prevent the offset rotary block 3 from rotating through the limiting column 4, thereby achieving the purpose of stopping the offset rotary block 3 when it swings into place.

[0033] In this embodiment, the transmission assembly includes a driven output gear 7, the offset rotary block 3 is fixedly connected to one side of the driven output gear 7, and the offset rotary block 3 is coaxially arranged with the driven output gear 7. That is, the offset rotary block 3 and the driven output gear 7 rotate synchronously.

[0034] To further explain, the driving assembly includes a motor 10 and a screw 11, and the motor 10 is rotatably connected to the screw 11; a mounting seat 9 is provided in the outer shell 12, the driving assembly is fixedly connected to the mounting seat 9, and the screw 11 is fixedly connected to the rotor of the motor 10. The transmission assembly includes a driving gear 6, a driven output gear 7 and a gear set 8, and the driving gear 6 is mainly a helical gear. The driving gear 6 is meshed with the screw 11, and the gear set 8 is meshed with the driving gear 6 and the driven output gear 7 respectively, and the driving gear 6 is transmission-connected to the driven output gear 7 through the gear set 8. The driven gear, the driven output gear 7 and the gear set 8 are all rotatably connected to the outer shell 12. The gear set 8 preferably uses a pair of gears, and a fixed shaft is also fixedly provided in the middle of the pair, and the pair of gears are separately meshed with the driven output gear 7 and the driving gear 6.

[0035] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. For ordinary technicians in this field, they can make several modifications and improvements without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
