[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] Reference Figures 1 to 4 This utility model provides a cam reciprocating motion mechanism, including a first housing 11, a steel shaft 12, a cam unit 13, a drive assembly 14, a cam shaft 15, and a soft rubber outer skin 16;

[0030] The two ends of the steel shaft 12 are connected to the inside of the first housing 11, and the steel shaft 12 can remain stationary relative to the first housing 11;

[0031] There are multiple cam units 13, which are sequentially mounted on the steel shaft 12. The cam units 13 arranged sequentially along the length of the steel shaft 12 can collectively form a wide coverage area.

[0032] The drive assembly 14 is connected inside the first housing 11 and is driven by the camshaft 15. After the drive assembly 14 is started, it can drive the camshaft 15 to rotate back and forth. The drive assembly 14 can output different power to adjust the speed of the camshaft 15, thereby adjusting the massage intensity.

[0033] All cam units 13 are located on the same side of the camshaft 15. All cam units 13 have a position height that matches the shape of the camshaft. During rotation, the camshaft 15 can simultaneously form a squeezing contact with all cam units 13 to drive all cam units 13 to move relative to each other. During the movement, if the camshaft 15 itself has a wave-shaped shape, then the reciprocating camshaft 15 can drive all cam units 13 to move up and down synchronously within a wide coverage area, thereby forming a wave-like massage technique and enhancing the massage experience.

[0034] The soft rubber outer skin 16 is connected to the first housing 11 and wraps around the side of all cam units 13 away from the camshaft 15, so that the cam units 13 are pressed tightly against the camshaft 15, and the cam units 13 are limited to a certain extent, so that the cam reciprocating motion mechanism runs more smoothly.

[0035] As an optional implementation, a through hole 131 is provided on the cam unit 13, and multiple cam units 13 are sequentially passed through the through hole 131 onto the steel shaft 12;

[0036] The through hole 131 is an elongated hole, and the length direction of the through hole 131 is perpendicular to the length direction of the steel shaft 12. The cam unit 13 and the steel shaft 12 can move relative to each other along the length direction of the through hole 131.

[0037] Based on this, each cam unit 13 can adjust its relative position to the steel shaft 12 through the through hole 131 so that different cam units 13 have a position height that matches the cam shaft 15.

[0038] Based on this, for the cam unit 13 located at the bottom, the through hole 131 preferably has enough space so that it can still move downward under the squeezing force of the camshaft 15 rotating.

[0039] As an optional implementation, there are two steel shafts 12 arranged in parallel to each other, and each cam unit 13 has two symmetrical through holes 131, and each through hole 131 is connected to a corresponding steel shaft 12.

[0040] The two steel shafts 12 can make the force more even and the structure more stable.

[0041] As an optional implementation, the drive component 14 is a motor, the output shaft of which is connected to the camshaft 15. After the motor is started, it can drive the camshaft 15 to rotate through the output shaft.

[0042] As an optional implementation, a bushing 17 is also included, which is connected inside the first housing 11, and the end of the camshaft 15 away from the drive assembly 14 is movably connected to the bushing 17.

[0043] The bushing 17 cooperates with the motor of the drive assembly 14, so that the camshaft 15 can be in a relatively suspended state, thereby improving the stability of the rotation of the camshaft 15 and reducing the excessive center deviation of the camshaft 15 during use.

[0044] As an optional implementation, there is preferably a gap between the outermost cam unit 13 and the first housing 11. This arrangement can reduce the jamming phenomenon of the cam unit 13 by setting the gap.

[0045] Based on this, it also includes an elastic component 18. Each end of each steel shaft 12 is fitted with an elastic component 18. The two ends of the elastic component 18 are in contact with the first housing 11 and the outermost cam unit 13, respectively. In this embodiment, the elastic component 18 can be further preferably a spring. The spring has good elasticity. By placing the spring between the first housing 11 and the outermost cam unit 13, the loosening phenomenon caused by the gap in the outermost cam unit 13 can be reduced. In addition, the spring can play a buffering role between the cam unit 13 and the first housing 11. Therefore, the sound can also be effectively controlled and the noise can be reduced.

[0046] Reference Figure 3 and Figure 4 The present invention also provides a massager, including the above-mentioned cam reciprocating motion mechanism, and further including a connecting mechanism and a negative pressure suction mechanism, wherein the two ends of the connecting mechanism are respectively connected to the cam reciprocating motion mechanism and the negative pressure suction mechanism;

[0047] With this configuration, the massager can not only achieve massage in the form of cam reciprocating motion through the cam reciprocating motion mechanism, but also achieve massage in the form of negative pressure suction through the negative pressure suction mechanism, thus enriching the basic functions of the massager. Users can flexibly choose to turn on the cam reciprocating motion mechanism alone, or turn on the negative pressure suction mechanism alone, or turn on both the cam reciprocating motion mechanism and the negative pressure suction mechanism at the same time, making flexible choices according to actual usage needs.

[0048] As an optional implementation, the connecting mechanism includes a soft rubber connector 21 and a metal hose 22. The two ends of the soft rubber connector 21 are connected to the cam reciprocating motion mechanism and the negative pressure suction mechanism, respectively. The metal hose 22 is disposed inside the soft rubber connector 21. The metal hose 22 can be bent, thereby causing the soft rubber connector 21 to bend and deform as a whole, so that a shaping angle can be formed between the cam reciprocating motion mechanism and the negative pressure suction mechanism. Here, the user can flexibly set the shaping angle according to the actual use requirements.

[0049] After the connecting mechanism is bent and deformed, the massager as a whole can form a C-shape or U-shape, or other deformable postures within the allowable range of deformation, so that the cam reciprocating motion mechanism and the negative pressure suction mechanism can be used simultaneously, improving the user's massage experience and enhancing the fun of massage.

[0050] As an optional implementation, the negative pressure suction mechanism includes a second housing 31, a tooth box 32, an eccentric wheel 33, a pull rod 34, a suction cup 35, a pressure plate 36, a channel cavity 37, and a massager opening 38.

[0051] The tooth box 32 is connected inside the second housing 31. The eccentric wheel 33 is sleeved on the rotating shaft of the tooth box 32. The two ends of the pull rod 34 are respectively connected to the eccentric wheel 33 and the pull ring end of the suction cup 35. The face end of the suction cup 35 is connected to the channel cavity 37 through the pressure plate 36. The channel cavity 37 is connected to the massager port 38. The inside of the channel cavity 37 can form a channel chamber. The massager port 38 is set on the second housing 31.

[0052] After the jaw box 32 is powered on, the eccentric wheel 33 can rotate with the rotating shaft of the jaw box 32, thereby driving the pull rod 34 and the pull ring end of the suction cup 35 to reciprocate to squeeze and pull up, thereby generating air pressure in the channel chamber of the channel cavity 37 to massage the skin that is in contact with the massager opening 38.

[0053] In addition, as an electronic product, the massager obviously needs to be equipped with a power supply unit 41. The power supply unit 41 is connected to the cam reciprocating motion mechanism and the negative pressure suction mechanism circuit, and can supply power to both of them. The power supply unit 41 can be a replaceable battery or a battery that can be recharged and discharged. The power supply unit 41 itself and its application principle are conventional existing technology, so they will not be described in further detail.

[0054] Furthermore, as an electronic product, the massager can preferably be equipped with a controller inside in order to control the cam reciprocating motion mechanism and the negative pressure suction mechanism respectively, and a switch button can preferably be provided on the outside. The controller and the switch button themselves and their application principles are conventional existing technologies, so they will not be described in detail or shown in the accompanying drawings.

[0055] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
