Description

Technical Field

[0001] This disclosure relates to the field of health care device technology, and in particular to a connecting device and a massage device. Background Technology

[0002] Massage devices, as health care instruments to relieve or eliminate physical fatigue, are becoming increasingly popular due to their flexibility and convenience. To achieve better massage effects, targeted massage devices are often designed based on the structural characteristics of different parts of the body, such as neck massagers, waist massagers, and shoulder and neck massagers. As people increasingly spend long hours in their work and daily lives, muscle discomfort is common, leading to a growing market demand for massage devices that can provide muscle massage.

[0003] In related technologies, some massage devices use transmission components such as eccentric wheels to drive the first massage head. However, when the first massage head is positioned above the transmission component, sufficient clearance needs to be reserved near the transmission component to avoid interference, resulting in a relatively bulky massage device, which is not conducive to miniaturization. Utility Model Content

[0004] This disclosure provides a connecting device and a massage device. The connecting device can effectively reduce motion interference near the transmission components, has a compact structure, and is conducive to the miniaturization of the massage device.

[0005] The technical solution is as follows: According to a first aspect of the present disclosure, a connecting device is provided, including a support assembly, a transmission assembly, and a connecting assembly. The support assembly has a first mounting portion. The transmission assembly includes a transmission member movably disposed on the support assembly, and the transmission member has a transmission portion spaced apart from the first mounting portion. The connecting assembly includes a sliding member slidably connected to the first mounting portion and a rotating member rotatably connected to the sliding member. One end of the rotating member has a first connecting portion, and the other end of the rotating member has a second connecting portion for connecting to a first massage head. The first connecting portion is drively connected to the transmission portion. The rotating member passes through the sliding member so that the second connecting portion is disposed outside the support assembly. When the transmission portion moves about a predetermined trajectory, the transmission portion can drive the rotating member to move, and cause the sliding member to slide relative to the support assembly.

[0006] The technical solution of this disclosure will be further explained below: In one embodiment, the set trajectory includes a first closed curve. The rotating member and the sliding member are universally hinged, and / or the first connecting part and the transmission part are universally hinged. When the transmission part moves along the first closed curve, the transmission part can drive the second connecting part to move along the second closed curve via the rotating member.

[0007] In one embodiment, the transmission part and the first mounting part are spaced apart along a first direction, and the bearing assembly includes a second mounting part spaced apart from the first mounting part along a second direction, the first direction intersecting the second direction. The transmission assembly also includes an eccentric wheel rotatably connected to the second mounting part. The transmission member has a first transmission body and a first transmission ring sleeved on the outside of the eccentric wheel. One end of the first transmission body is fixedly connected to the first transmission ring, and the transmission part is disposed at the other end of the first transmission body. When the eccentric wheel rotates, the eccentric wheel and the first transmission ring rotate eccentrically to drive the transmission part to move around a first closed curve.

[0008] In one embodiment, at least a portion of the first closed curve is arc-shaped, and when the transmission part moves along the first closed curve, the transmission part can also drive the second connecting part to move closer to or away from the first mounting part.

[0009] And / or, the rotating part and the sliding part are universally hinged, and the transmission part and the first connecting part are axially hinged or ball-jointed.

[0010] In one embodiment, a portion of the rotating member is spherical and is ball-hinged with the sliding member to enable universal hinge between the rotating member and the sliding member.

[0011] In one embodiment, the first mounting portion includes a slide groove, a first clearance opening communicating with the slide groove, and a second clearance opening communicating with the slide groove. The first clearance opening and the second clearance opening are spaced apart at both ends of the slide groove along a first direction. A sliding member is slidably disposed in the slide groove, and a portion of a rotating member passes through the first clearance opening, such that a first connecting portion is disposed outside the first clearance opening. A portion of the rotating member passes through the second clearance opening, such that a second connecting portion is disposed outside the second clearance opening.

[0012] In one embodiment, the slider has a spherical hole with a first notch facing a first clearance opening and a second notch facing a second clearance opening. The rotating member includes a connecting rod protruding from the first and second notches and a ball head fixed to the connecting rod. The ball head is spherically hinged to the spherical hole to rotatably connect the connecting rod and the slider. One end of the connecting rod has a first connecting portion, and the other end of the connecting rod has a second connecting portion.

[0013] In one embodiment, the connecting rod includes a first rod body with a first connecting portion and a second rod body with a second connecting portion, the first rod body and the second rod body being intersected.

[0014] And / or, the sliding element includes a first sliding body having a first spherical concave surface and a second sliding body having a second spherical concave surface. The first sliding body and the second sliding body are fixedly connected so that the first spherical concave surface and the second spherical concave surface cooperate to form a spherical hole.

[0015] In one embodiment, one of the first sliding body and the second sliding body is provided with a latching protrusion, and the other is provided with a latching hole that engages with the latching protrusion.

[0016] According to a second aspect of the present disclosure, a massage device is also provided, including a housing assembly, a first massage head, a power mechanism, and a connecting device as described in any of the above embodiments. A supporting assembly is fixed to the housing assembly. The first massage head is connected to a second connecting portion. The power mechanism is disposed on the housing assembly and drives a rotating component to move via a transmission assembly.

[0017] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects: When a massage is needed, the power mechanism generates power, which drives the transmission component to rotate via the transmission assembly, causing the transmission part to move along a set trajectory. Since the first connecting part is rotatably connected to the transmission part, it can drive the rotating component to rotate relative to the sliding component, thereby driving the first massage head mounted on the rotating component to rotate. During this process, because the sliding component is slidably connected to the support component, the rotating component can slide relative to the support component via the sliding component, which in turn can drive the first massage head to move closer to or away from the sliding component. Thus, through the cooperation of the sliding component and the rotating component, the movement of the first massage head can be controlled, and the connection structure between the rotating component and the transmission component can be simplified. This connection device effectively reduces motion interference near the transmission component, has a compact structure, and is conducive to the miniaturization of massage equipment.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and do not limit the scope of protection of this disclosure.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure.

[0031] To better understand the connection device of this disclosure, it will be described using a massage device in which the connection device is applied.

[0032] like Figures 1 to 4 As shown in the embodiments of this disclosure, a massage device 1 is provided, including a housing assembly 10, a first massage head 20, a power mechanism 30, and a connecting device 40. The connecting device 40 includes a support assembly 100, a transmission assembly 200, and a connecting assembly 300 fixed to the housing assembly 10. The support assembly 100 is provided with a first mounting portion 110. The transmission assembly 200 includes a transmission member 210 movably disposed on the support assembly 100, and the transmission member 210 is provided with a transmission portion 211 spaced apart from the first mounting portion 110. The connecting assembly 300 includes a sliding member 310 slidably connected to the first mounting portion 110 and a rotating member 320 rotatably connected to the sliding member 310. One end of the rotating member 320 is provided with a first connecting portion 301, and the other end of the rotating member 320 is provided with a second connecting portion 302 connected to the first massage head 20. The first connecting portion 301 is drively connected to the transmission portion 211. The rotating member 320 passes through the sliding member 310 so that the second connecting portion 302 is disposed outside the support assembly 100. When the transmission unit 211 moves along a set trajectory, it can drive the rotating member 320 to move and slide relative to the sliding member 310. The power mechanism 30 is provided in the housing assembly 10 and drives the rotating member 320 to move through the transmission assembly 200.

[0033] When massage is needed using the massage device 1, the power mechanism 30 generates power, which drives the transmission component 210 to rotate via the transmission assembly 200, causing the transmission part 211 to move around a set trajectory. Since the first connecting part 301 is rotatably connected to the transmission part 211, it can drive the rotating component 320 to rotate relative to the sliding component 310, thereby driving the first massage head 20 mounted on the rotating component 320 to rotate. During this process, because the sliding component 310 is slidably connected to the support component, the rotating component 320 can slide relative to the support assembly 100 via the sliding component 310, and can also drive the first massage head 20 to move closer to or away from the sliding component 310. Furthermore, through the cooperation of the sliding component 310 and the rotating component 320, the movement of the first massage head 20 can be controlled, and the connection structure between the rotating component 320 and the transmission component 210 can be simplified. This connecting device 40 can effectively reduce motion interference near the transmission assembly 200, has a compact structure, and is conducive to the miniaturization of the massage device 1.

[0034] Understandably, the slider 310 can slide relative to the support component 100, while the rotating component 320 can rotate relative to the slider 310. As the transmission part 211 drives the rotating component 320 to rotate through the first connecting part 301, the second connecting part 302 also rotates and can slide relative to the support component 100 during the rotation, so that the first massage head 20 can generate compound motion to better massage the user's body.

[0035] In addition, the first massage head 20 is independently assembled on the connecting device 40 through the second connecting part 302, and will not interfere with the moving components such as the power mechanism 30 and the transmission component 200 on the housing assembly 10. This also makes the massage device 1 less need to set up a large amount of clearance space, with a compact structure, which is conducive to further miniaturization of the massage device 1.

[0036] Optionally, the rotating member 320 can drive the first massage head 20 to reciprocate, reciprocate along a two-dimensional closed curve (e.g., along a circular curve or an elliptical curve), or reciprocate along a three-dimensional closed curve (e.g., an elliptical trajectory curved around a spherical convex surface). The reciprocating motion should be interpreted broadly.

[0037] It should be noted that the "set trajectory" includes straight lines, arcs, closed curves, etc., which can be flexibly set according to the motion trajectory to be achieved by the first massage head 20.

[0038] For example, when the first massage head 20 needs to perform a pinching motion, the trajectory is set to a straight line. At this time, the transmission member 210 can extend and retract to drive the first connecting part 301 to also extend and retract, and through the control of the sliding member 310, the second connecting part 302 can drive the first massage head 20 to perform a pinching motion.

[0039] For example, when the first massage head 20 needs to perform a kneading motion, the trajectory is set to a closed curve. At this time, the transmission component 210 can achieve eccentric motion through the eccentric component, thereby driving the transmission part 211 to move around the closed curve, which in turn drives the first connecting part 301 to also move around the closed curve. Furthermore, through the control of the sliding component 310, the second connecting part 302 can drive the first massage head 20 to perform the kneading motion. For example, when the transmission component 210 swings, the trajectory is set to be arc-shaped.

[0040] In some embodiments, the set trajectory includes a first closed curve. When the transmission part 211 moves along the first closed curve, the transmission part 211 can drive the second connecting part 302 to move along the second closed curve via the rotating member 320. Thus, when the power mechanism 30 drives the transmission part 211 to move along the first closed curve, since the rotating member 320 is universally hinged to the sliding member 310, and / or the first connecting part 301 is universally hinged to the transmission part 211, it can adapt to the movement trajectory of the transmission part 211, so that the transmission part 211 can drive the second connecting part 302 to move along the second closed curve via the rotating member 320. At this time, the second connecting part 302 can drive the first massage head 20 to perform three-dimensional movement to simulate the kneading massage of a human hand and improve the massage effect of the massage device 1.

[0041] Combination Figure 4 as well as Figure 5 In some embodiments, the transmission part 211 and the first mounting part 110 are spaced apart along a first direction. The bearing assembly 100 includes a second mounting part 120 spaced apart from the first mounting part 110 along a second direction, which intersects the first direction. The transmission assembly 200 also includes an eccentric wheel 220 rotatably connected to the second mounting part 120. The transmission member 210 is provided with a first transmission body 212 and a first transmission ring 213 sleeved on the outside of the eccentric wheel 220. One end of the first transmission body 212 is fixedly connected to the first transmission ring 213, and the transmission part 211 is disposed at the other end of the first transmission body 212. When the eccentric wheel 220 rotates, the eccentric wheel 220 and the first transmission ring 213 rotate eccentrically to drive the transmission part 211 to move around a first closed curve. Thus, through the eccentric transmission cooperation between the eccentric wheel 220 and the first transmission ring 213, the transmission part 211 moves around the first closed curve, and the transmission part 211 can drive the second connecting part 302 to move along the second closed curve, and the second connecting part 302 can also drive the first massage head 20 to perform three-dimensional movement to simulate the kneading massage of a human hand and improve the massage effect of the massage device 1.

[0042] Understandably, when the transmission part 211 moves eccentrically, it is spaced apart from the first mounting part 110 along the first direction, so that the two do not interfere with each other. The second mounting part 120 is also spaced apart from the first mounting part 110 along the second direction, so that the sliding member 310 and the eccentric wheel 220 do not interfere with each other. This helps to shorten the length of the first transmission body 212 and makes the fit between the transmission assembly 200 and the connecting assembly 300 tighter.

[0043] Furthermore, the cooperation between the transmission ring and the first transmission body 212 ensures that the transmission part 211 and the eccentric wheel 220 are also spaced apart, so that the movement of the rotating part 320 will not interfere with the movement of the eccentric wheel 220, and the space occupied is small.

[0044] It should be noted that "universal joint" should be interpreted broadly, meaning that, compared to a axial joint, it has at least two directions of rotation. This can be achieved through ball joints, couplings, etc.

[0045] like Figure 4 As shown, the first direction is the X-axis direction, and the second direction is the Z-axis direction. (Refer to the attached diagram.) Figure 3 It is understood that the slider 310 and the rotating member 320 will not move in the second direction, and thus the slider 310 is confined within the first mounting portion 110, and will not interfere with the parts below the first connecting portion 301, such as the gear structure 34.

[0046] It should be noted that there are various ways to achieve the rotatable connection between the second mounting part 120 and the eccentric wheel 220, including but not limited to indirect rotatable connection via a rotating shaft. Alternatively, the eccentric wheel 220 may be fixed with a rotating shaft, and the eccentric wheel may be directly rotatably connected to the second mounting part 120 via the rotating shaft. This can be achieved through various conventional means, and no limitation is made here, as long as the rotatable connection requirement between the two is met.

[0047] like Figure 4 as well as Figure 5 As shown, in some embodiments, at least a portion of the first closed curve is arc-shaped. When the transmission part 211 moves along the first closed curve, the transmission part 211 can also drive the second connecting part 302 to move closer to or away from the first mounting part 110. Thus, as the transmission part 211 drives the rotating member 320 to rotate through the first connecting part 301, the second connecting part 302 also rotates and can slide relative to the slide groove 111 during the rotation, allowing the first massage head 20 to generate compound motion for better massage of the user's body.

[0048] In some embodiments, the first closed curve includes an elliptical trajectory or a circular trajectory.

[0049] like Figure 4 as well as Figure 5 As shown, in some embodiments, the rotating member 320 and the sliding member 310 are universally hinged, and the transmission part 211 is axially hinged or ball-jointed with the first connecting part 301. Thus, the universal hinge between the rotating member 320 and the sliding member 310 facilitates full utilization of the internal space of the bearing assembly 100. Furthermore, because the universal hinge between the rotating member 320 and the sliding member 310 can satisfy the space required for the eccentric movement of the transmission part 211, various rotational connection methods between the transmission part 211 and the first connecting part 301 can be used, allowing for flexible selection based on actual needs.

[0050] Understandably, when the transmission part 211 and the first connecting part 301 are hinged together, the assembly cost of the two is low and the space occupied is small.

[0051] It should be noted that "shaft hinge" should be interpreted broadly, including the use of structures such as rotating shafts and shaft bodies 201 to enable the rotating component 320 to move around an elliptical trajectory.

[0052] In conjunction with the above-described embodiment of the slide groove 111, such as Figure 4 as well as Figure 5 As shown, in some embodiments, the transmission part 211 is provided with a shaft 201, and the first connecting part 301 is provided with a hinge hole 3011 that rotatably engages with the shaft 201. In this way, the shaft hinge engagement between the hinge hole 3011 and the shaft 201 facilitates assembly and realizes the shaft hinge connection between the rotating part 320 and the transmission part 210.

[0053] In combination with any of the above embodiments, such as Figure 4 as well as Figure 5 As shown, in some embodiments, a portion of the rotating member 320 is spherical and is spherically hinged to the sliding member 310, so that the rotating member 320 and the sliding member 310 are universally hinged. In this way, the rotating member 320 can achieve universal motion around the center of the sphere and can slide relative to the support assembly 100, which can satisfy the requirement that the rotating member 320 be driven by the transmission part 211 with different set trajectories.

[0054] For example, when the trajectory is set to a straight line, an arc, or a closed curve, the sliding member 310 can be used to limit the rotation of the rotating member 320, so that the rotating member 320 will not interfere with the movement of the transmission member 210.

[0055] In conjunction with the above embodiments, such as Figure 4 as well as Figure 5As shown, in some embodiments, the first mounting portion 110 includes a slide groove 111, a first clearance opening 112 communicating with the slide groove 111, and a second clearance opening 113 communicating with the slide groove 111. The first clearance opening 112 and the second clearance opening 113 are spaced apart at both ends of the slide groove 111 along a first direction. The sliding member 310 is slidably disposed in the slide groove 111, and a portion of the rotating member 320 passes through the first clearance opening 112, so that the first connecting portion 301 is disposed outside the first clearance opening 112. A portion of the rotating member 320 passes through the second clearance opening 113, so that the second connecting portion 302 is disposed outside the second clearance opening 113. In this way, the sliding member 310 is confined within the slide groove 111, which can fully utilize the internal space of the supporting component 100 to accommodate the sliding member 310, so that the two fit tightly together. Meanwhile, by providing the first clearance opening 112 and the second clearance opening 113, the omnidirectional rotation range of the rotating member 320 can be avoided, and the movement of the rotating member 320 will not be interfered with. Moreover, the rotating member 320 can be disposed through the first clearance opening 112 and the second clearance opening 113, so that the first connecting part 301 and the second connecting part 302 can also be disposed at intervals, thereby the first massage head 20 connected to the second connecting part 302 will not interfere with the movement of the transmission member 210 connected to the first connecting part 301.

[0056] Furthermore, such as Figure 4 As shown, in some embodiments, the slider 310 is provided with a spherical hole 311, which has a first notch facing the first clearance opening 112 and a second notch facing the second clearance opening 113. The rotating member 320 includes a connecting rod 321 protruding from the first and second notches and a ball head 322 fixed to the connecting rod 321. The ball head 322 is spherically hinged to the spherical hole 311, so that the connecting rod 321 is rotatably connected to the slider 310. One end of the connecting rod 321 is provided with a first connecting portion 301, and the other end of the connecting rod 321 is provided with a second connecting portion 302. Thus, the universal hinge between the rotating member 320 and the slider 310 is achieved through the engagement of the ball head 322 and the spherical hole 311. At the same time, by using the connecting rod 321 to pass through the first notch and the first clearance opening 112 to position the first connecting portion 301 below the first clearance notch, it is easy to connect to the transmission part 211. The second connecting part 302 is positioned above the second clearance notch by passing the connecting rod 321 through the second notch and the second clearance opening 113, making it easy to connect to the first massage head 20.

[0057] It should be noted that there are multiple ways to fix the ball head 322 to the connecting rod 321, including but not limited to welding, pin 323, snap fastener, etc.

[0058] Optionally, such as Figure 4 as well as Figure 5As shown, in some embodiments, the ball head 322 is provided with a mounting through hole 3221, and a portion of the connecting rod 321 passes through the mounting through hole 3221 and is fixed by a pin 323.

[0059] Optionally, such as Figure 5 As shown, in some embodiments, the connecting rod 321 includes a first rod body 3211 with a first connecting portion 301 and a second rod body 3212 with a second connecting portion 302, the first rod body 3211 and the second rod body 3212 being intersected. Thus, by intersecting the first rod body 3211 and the second rod body 3212, the movement trajectories of the first connecting portion 301 and the second connecting portion 302 intersect, facilitating the movement of the first connecting rod via the transmission part 211, thereby driving the first massage head 20 on the second connecting rod to perform kneading motion, thus improving the massage effect of the massage device 1.

[0060] like Figure 4 as well as Figure 5 As shown, in some embodiments, the slider 310 includes a first slider 312 with a first spherical concave surface 303 and a second slider 313 with a second spherical concave surface 304. The first slider 312 and the second slider 313 are fixedly connected so that the first spherical concave surface 303 and the second spherical concave surface 304 cooperate to form a spherical hole 311. In this way, the ball head 322 is placed on the first spherical concave surface 303, and then the second slider 313 is fixedly connected to the first slider 312 so that the first spherical concave surface 303 and the second spherical concave surface 304 cooperate to form a spherical hole 311 that restricts the movement of the ball head 322, which is easy to assemble and realizes the universal hinge between the rotating member 320 and the slider 310.

[0061] It should be noted that there are various ways to achieve the fixed connection between the first sliding body 312 and the second sliding body 313, including but not limited to welding, bonding, snap-fitting, screwing, etc.

[0062] Optionally, such as Figure 5 As shown, in some embodiments, one of the first sliding body 312 and the second sliding body 313 is provided with a locking protrusion 305, and the other is provided with a locking hole 306 that engages with the locking protrusion 305. In this way, when the first sliding body 312 and the second sliding body 313 are assembled, they can be fixed by locking the locking protrusion 305 into the locking hole 306, which makes assembly easy.

[0063] It should be noted that there are various ways to connect the housing assembly 10 and the load-bearing assembly 100, including but not limited to screw fixing, snap fixing, welding fixing, adhesive fixing, and integral molding, etc.

[0064] In some embodiments, the support assembly 100 is assembled and fixed to the housing assembly 10. In this case, the connecting device 40 is modularly assembled onto the housing assembly 10 using the support assembly 100.

[0065] In some embodiments, the support component 100 is integrally formed with the housing component 10. In this case, the structure of the connecting device 40 can be assembled onto the housing component 10 together with the power mechanism 30, etc.

[0066] It should be noted that the power mechanism 30 can be implemented in various ways, including but not limited to motor + gear transmission mechanism, motor + belt transmission mechanism, motor + chain transmission mechanism, etc.

[0067] In one example, such as Figure 6 As shown, the power mechanism 30 includes a power source 31, a worm gear 32 driven by the power source 31, a worm wheel 33 driven by the worm gear 32, and a gear structure 34 driven by the worm wheel 33. The transmission assembly 200 is driven by the gear structure 34. Optionally, the driven gear of the gear structure 34 is coaxially driven by an eccentric wheel 220 or a second eccentric wheel 220.

[0068] It should be noted that the second closed curve includes two-dimensional closed curves (e.g., along circular curves, or elliptical curves, etc.), or three-dimensional closed curves (e.g., elliptical trajectories curved around the convex surface of a sphere), etc.

[0069] Furthermore, the design of the second closed curve can be flexibly tailored to the characteristics of the human body's curves, and its specific implementation methods include spiral curves, circular curves, etc. For example, the second connecting part 302 can be designed with a second closed curve based on the curve of the human back to drive the first massage head 20 to knead the human shoulder. Alternatively, the second connecting part 302 can be designed with a second closed curve based on the curve of the human back to drive the first massage head 20 to knead the human back. Alternatively, the second connecting part 302 can be designed with a second closed curve based on the curve of the human waist to drive the first massage head 20 to knead the human waist. Alternatively, the second connecting part 302 can be designed with a second closed curve based on the curve of the human hips to drive the first massage head 20 to knead the human hips. Alternatively, the second connecting part 302 can be designed with a second closed curve based on the curve of the human thighs to drive the first massage head 20 to knead the human thighs.

[0070] It should be noted that there is no limit to the number of the first massage heads 20, including but not limited to 1, 2, 3, etc., which can be flexibly designed according to actual massage needs.

[0071] like Figure 7As shown, in some embodiments, the first massage head 20 can massage the neck of the human body. The connecting device 40 includes two units, spaced apart on both sides of the housing assembly 10. The first massage head 20 also includes two units, each connected to the second connecting portion 302. Thus, the massage device 1 can massage the muscles on both sides of the neck, increasing the massage range and improving massage efficiency.

[0072] like Figure 7 As shown, in some embodiments, the massage device 1 further includes a second massage head 50, and the power mechanism 30 can drive the second massage head 50 to move.

[0073] It should be noted that the movement trajectory of the second massage head can be flexibly designed according to the curve of the body part to be massaged, as long as it can simulate the kneading massage effect of human hands. For example, when using the second massage head to massage the shoulders, it can move from the scapula towards the spine, and after reaching the first preset position, it can move towards the neck. After reaching the second preset position above the first preset position, it can move from the spine towards the scapula again. This process is repeated to achieve kneading. Of course, it can also move in the opposite direction, from the spine towards the scapula to the second preset position... Alternatively, the second massage head moves from the initial position down the rhomboid muscles (or other shoulder muscles) towards the back, then towards the spine, then towards the neck, and finally back to the initial position. This repeated motion achieves a kneading effect. Of course, the movement can also be reversed, moving from the initial position towards the neck… For example, when using the second massage head for a back massage, it can move from the side of the body towards the spine, reaching a first preset position, and then moving towards the neck. After reaching a second preset position above the first preset position, it then moves back from the spine towards the side of the body. This process is repeated to achieve kneading. Of course, the movement can also be reversed.

[0074] It should be noted that there is no limit to the number of the second massage heads, including but not limited to 1, 2, 3, etc., which can be flexibly designed according to actual massage needs.

[0075] For example, when the second massage head is used to massage the human shoulder, if there are two second massage heads, the movement of the second massage head can drive the two second massage heads to massage the upper and lower parts of the human shoulder simultaneously.

[0076] For example, when the second massage head is used to massage the back of the human body, if there are three second massage heads, the movement of the second massage head can drive the three second massage heads to massage the upper, middle and lower parts of the back at the same time.

[0077] It should be noted that "kneading massage" should be interpreted broadly, including back-and-forth swaying, back-and-forth rotation, and back-and-forth movement along a set trajectory. The massage intensity on the human muscles can be applied back and forth from light to heavy.

[0078] In the description of this disclosure, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0079] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include at least one of that feature. In the description of this disclosure, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0080] In this disclosure, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0081] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0082] It should be noted that when a component is described as "fixed to," "set on," "fixed to," or "installed on" another component, it can be directly on the other component or there may be an intervening component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intervening component. Furthermore, when a component is considered to be "fixedly connected" to another component, the connection can be detachable or non-detachable, such as screw fixing, snap-fit ​​fixing, integral molding fixing, welding fixing, etc., which can be achieved in conventional technologies and will not be elaborated here.

[0083] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0084] The above embodiments are merely illustrative of several implementation methods of this disclosure, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept of this disclosure, and these modifications and improvements all fall within the protection scope of this disclosure.
