Description

Technical Field

[0001] This application relates to the field of massage devices, and in particular to a massage device and massage equipment. Background Technology

[0002] As living standards improve, more and more people are investing in their health, and massage devices designed to relieve fatigue in areas such as the neck, shoulders, and lower back are becoming increasingly popular. These devices typically have at least one massage head that contacts the user's area and applies pressure to relieve muscle soreness.

[0003] However, in these related technologies, when these massage heads make contact with the user's massage area, the massage pressure applied by the massage head is harsh, exacerbating the user's discomfort and pain. Furthermore, these massage heads can also abrade the skin of the massaged area, resulting in poor user massage comfort. Utility Model Content

[0004] In view of this, this application provides a massage device and a massage equipment that can improve the softness of the massage head to reduce the discomfort caused to the user's massage area, while also avoiding abrasion of the skin of the massage area, thereby improving the user's massage comfort.

[0005] Specifically, this application is implemented through the following technical solution:

[0006] According to a first aspect of the embodiments of this application, a massage device is provided, including a support assembly and a massage component. The support assembly includes a connecting frame and at least two connecting shafts connected to the connecting frame, with each connecting shaft spaced apart from the others. The massage component includes at least two massage heads corresponding one-to-one with the at least two connecting shafts, each massage head being rotatably sleeved on each connecting shaft, and at least one of the at least two massage heads having a hollow structure.

[0007] In one embodiment, the massage head includes a first connecting surface and a second connecting surface spaced apart along the connecting shaft, and a massage surface connected between the first connecting surface and the second connecting surface, with a hollow structure connected between the first connecting surface and the second connecting surface.

[0008] In one embodiment, the perforated structure includes at least two hole layers that are radially separated along the connecting axis, each hole layer having a different hole shape and / or hole size.

[0009] In one embodiment, each hole layer includes at least one of circular holes, elliptical holes, square holes, polygonal holes, irregular holes, and spiral holes.

[0010] In one embodiment, the hole size of each hole layer increases sequentially along the direction from the connecting shaft toward the massage surface.

[0011] In one embodiment, the connecting frame has a mounting groove and a drive connection portion located within the mounting groove, with each connecting shaft located outside the mounting groove and connected to the side wall of the mounting groove, so that at least a portion of each massage head can protrude from the bottom wall of the mounting groove.

[0012] In one embodiment, the connecting frame is further provided with at least two recessed relief portions, which are arranged in a one-to-one correspondence with at least two connecting shafts, and each massage head is partially located within each relief portion.

[0013] In one embodiment, the connecting frame is further provided with a support rib connecting the mounting groove and the drive connection part.

[0014] In one embodiment, at least two connecting shafts include a first connecting shaft and a second connecting shaft, and the massage assembly includes a first massage head located on the first connecting shaft and a second massage head located on the second connecting shaft. In the depth direction along the mounting groove, the dimension d1 of the first massage head protruding from the bottom wall of the mounting groove is not less than the dimension d2 of the second massage head protruding from the bottom wall of the mounting groove.

[0015] In one embodiment, the massage device further includes a drive member and a positioning member. The drive connection part is provided with an insertion hole arranged along the depth direction of the mounting groove. The bottom wall of the mounting groove is provided with a positioning hole communicating with the insertion hole. The drive member is located in the insertion hole, and the positioning member is located in the positioning hole and is fixedly connected to the drive member.

[0016] In one embodiment, the massage device further includes a limiting component located between the connecting shaft and the massage head, the limiting component being used to limit the axial movement distance of the massage head along the connecting shaft.

[0017] In one embodiment, the limiting component includes a bushing fitted onto the connecting shaft and a fastener connecting the bushing and the connecting shaft. The massage head is provided with a limiting hole that mates with the bushing, and the bushing abuts against the limiting hole.

[0018] According to a second aspect of the embodiments of this application, a massage device is provided, including a device body, a transmission mechanism and the aforementioned massage device, wherein a connecting frame is movably connected to the device body, and the transmission mechanism is connected between the device body and the connecting frame, enabling the connecting frame to move relative to the device body.

[0019] The technical solutions provided by the embodiments of this application have at least the following beneficial effects:

[0020] In the massage device provided in this application, a connecting frame is movably connected to the massage equipment, allowing the entire massage device to move relative to the massage area. This enables each massage head to individually contact the user's massage area for massage. Simultaneously, the connecting frame is equipped with connecting shafts to support the massage heads. Each massage head is rotatably mounted on its respective connecting shaft, allowing it to rotate axially around the connecting shaft during the movement of the connecting frame. This enables the massage head to roll relative to the massage area, reducing sliding friction between the massage head and the massage area and preventing abrasion of the skin. Furthermore, the massage head features a perforated structure. When the massage head contacts and presses against the user's massage area, it squeezes the perforated structure, utilizing its elastic deformation to cushion the pressure and discomfort on the user's massage area. This perforated structure increases the softness of the massage head, reducing the harshness of the applied force.

[0021] Thus, the massage device provided in this application can, on the one hand, allow the massage head to roll relative to the massage area during the massage process to avoid the massage head rubbing against the skin of the massage area, and on the other hand, improve the softness of the massage head to reduce the pain caused by the massage head to the user's massage area, thereby improving the user's massage comfort.

[0022] Understandably, the massage device provided in this application can be used with massage equipment, which is not limited to head massage equipment, neck massage equipment, shoulder massage equipment, waist massage equipment, foot massage equipment or fascia gun, etc., and can also include any equipment used by users who need a massage experience. This application does not limit this.

[0023] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

Detailed Implementation

[0035] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0036] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, height, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures). If the specific posture changes, the directional indications or positional relationships will also change accordingly.

[0037] As living standards improve, more and more people are investing in their health, and massage devices designed to relieve fatigue in areas such as the neck, shoulders, and lower back are becoming increasingly popular. These devices typically have at least one massage head that contacts the user's area and applies pressure to relieve muscle soreness.

[0038] In related technologies, these massage heads are often designed to be relatively stiff to overcome abrasion. However, when these massage heads come into contact with the user's massage area, the pressure applied by the massage head can be harsh, exacerbating the user's discomfort and even causing abrasion to the skin, resulting in poor massage comfort.

[0039] Based on this, this application provides a massage device and a massage equipment, which on the one hand enables the massage head to roll relative to the massage area during the massage process to avoid the massage head rubbing against the skin of the massage area, and on the other hand can improve the softness of the massage head to reduce the pain caused by the massage head to the user's massage area, thereby improving the user's massage comfort.

[0040] Understandably, the massage device provided in this application can be used with massage equipment, which is not limited to head massage equipment, neck massage equipment, shoulder massage equipment, waist massage equipment, foot massage equipment or fascia gun, etc., and can also include any equipment used by users who need a massage experience. This application does not limit this.

[0041] To better understand the massage device provided in this application, the massage device provided in this application will be described below.

[0042] This application provides a massage device, including a massage unit 1, a device body, and a transmission mechanism. The massage unit 1 is movably mounted to the device body, and the transmission mechanism is connected between the massage unit 1 and the device body to drive the massage unit 1 to move relative to the device body, so that the massage unit 1 can massage the user's massage area.

[0043] Understandably, the massage device (not shown in the figure) may include a lumbar massage device, the main body of which may include a massage belt for easy wearing by the user. The massage device may also include a shoulder and neck massage device, the main body of which may include a massage neck brace for easy wearing by the user or a massage pillow for easy support of the user's shoulders and neck. The massage device also includes a back massage device, the main body of which may include a cushion or chair for easy support by the user; this application does not impose any limitations.

[0044] The transmission mechanism includes gear mechanisms or linkage mechanisms, etc. The movement of the massage device 1 relative to the main body of the device includes rotation and / or sliding, etc., which are not limited in this application. In this way, the transmission mechanism can be used to transmit the driving force of the main body of the device to the massage device 1, so that the massage device 1 can move relative to the main body of the device, thereby massaging the user's massage area.

[0045] To improve the massage comfort of the user's massage area, this application also provides a massage device 1. The massage device 1 provided by this application will be described below.

[0046] See Figure 1 and Figure 2 The massage device 1 provided in this application includes a support assembly 10 and a massage assembly 20. The support assembly 10 includes a connecting frame 11 and at least two connecting shafts connected to the connecting frame 11, with each connecting shaft spaced apart from the others. The massage assembly 20 includes at least two massage heads corresponding to each of the at least two connecting shafts, each massage head being rotatably sleeved on each connecting shaft, and at least one of the at least two massage heads having a hollow structure 23.

[0047] It should be noted that the connecting frame 11 is movably arranged relative to the main body of the massage device, and the transmission mechanism of the massage device is connected between the connecting frame 11 and the main body of the device to drive the connecting frame 11 to move and drive the massage device 1 to move relative to the main body of the device, so that the massage device 1 as a whole can move relative to the massage area to massage the massage area.

[0048] During the use of the massage device 1, the massage head of the massage component 20 can contact the user's massage area and move with the connecting frame 11. The massage head is connected to the connecting frame 11 via a connecting shaft, and the massage head can rotate relative to the connecting shaft, allowing it to rotate axially around the connecting shaft while moving with the connecting frame 11. This configuration allows the massage head to roll relative to the massage area, thereby reducing sliding friction between the massage head and the massage area and preventing the massage head from abrading the skin at the massage area.

[0049] Meanwhile, in the massage device 1 provided in this application, the massage head is also provided with a hollow structure 23. When the massage head comes into contact with and is pressed against the user's massage area, the massage head can squeeze the hollow structure 23 to cushion the pressure and pain on the user's massage area by utilizing the elastic deformation of the hollow structure 23. With this configuration, the massage head can increase its softness through the hollow structure 23 to reduce the harshness of the force applied to the massage area.

[0050] Thus, the massage device 1 provided in this application can, on the one hand, allow the massage head to roll relative to the massage area during the massage process to avoid the massage head rubbing against the skin of the massage area, and on the other hand, improve the softness of the massage head to reduce the pain caused by the massage head to the user's massage area, thereby improving the user's massage comfort.

[0051] Understandably, the connecting frame 11 and each connecting shaft can be fixedly connected by welding, gluing, or integral molding. The connecting frame 11 and each connecting shaft can also be detachably connected by plug-in or threaded connection, and this application does not impose any restrictions.

[0052] Understandably, the support assembly 10 may include multiple connecting shafts, such as 2, 3, 4, or 5, and each connecting shaft may be arranged at equal or unequal intervals and connected to the connecting frame 11 respectively; this application does not impose any limitation. Correspondingly, multiple massage heads may be provided, such as 2, 3, 4, or 5, and at least one massage head has a hollow structure 23; this application does not impose any limitation.

[0053] See Figure 2 and Figure 3 In some embodiments, to facilitate the movement of the drive connecting frame 11, the connecting frame 11 is provided with a mounting groove 111 and a drive connecting part 112 located in the mounting groove 111. Each connecting shaft is located outside the mounting groove 111 and connected to the side wall 1112 of the mounting groove, so that at least a portion of each massage head can protrude from the bottom wall 1111 of the mounting groove.

[0054] It should be noted that the drive connection part 112 can be used to connect with the transmission mechanism, and by placing the drive connection part 112 in the mounting groove 111, at least a portion of the transmission mechanism can be accommodated in the mounting groove 111, thereby protecting the installation of the transmission mechanism and the drive connection part 112. At the same time, the mounting groove 111 can also provide clearance space for the connection between the transmission mechanism and the drive connection part 112, thereby improving the neatness of the appearance and the compactness of the structure of the massage device 1.

[0055] In addition, by placing the connecting shaft outside the mounting slot 111, it is easy to install the massage head onto the connecting shaft and also easy for the massage head to contact the massage area.

[0056] See Figure 2 and Figure 3 In some embodiments, the connecting frame 11 is further provided with at least two clearance portions 114 recessed into the mounting groove 111. The at least two clearance portions 114 are arranged in a one-to-one correspondence with at least two connecting shafts, and each massage head can be partially located within each clearance portion 114.

[0057] With this configuration, at least one recessed portion formed by the clearance portion 114 can press against the drive connection portion 112 within the mounting groove 111, thereby increasing the support strength for the drive connection portion 112 and enabling the drive connection portion 112 to transmit the torque of the transmission mechanism. As an example, the recessed portion of the clearance portion 114 can form an arc-shaped structure, and the arc-shaped convex surface of the arc-shaped structure can press against the drive connection portion 112.

[0058] In addition, the clearance portion 114 can also be used to accommodate part of the massage head to further improve the structural compactness of the massage device 1.

[0059] See Figure 2 To improve the structural strength of the connecting frame 11, the connecting frame 11 is also provided with a support rib 113 connecting the mounting groove 111 and the drive connection part 112. Understandably, the connecting frame 11 may be provided with at least one of the clearance part 114 and the support rib 113, and this application does not impose any limitation.

[0060] See Figures 4 to 6 Taking the rotation of the drive connecting frame 11, which in turn drives the massage head to move relative to the massage area, as an example, the drive connecting part 112 is provided with an insertion hole along the depth direction of the mounting groove 111, and the bottom wall 1111 of the mounting groove is provided with a positioning hole 115 communicating with the insertion hole. The massage device 1 also includes a drive member 30 and a positioning member 40. The drive member 30 is located in the insertion hole, and the positioning member 40 is located in the positioning hole 115 and is fixedly connected to the drive member 30.

[0061] It should be noted that one end of the driving component 30 can be inserted into the socket to connect with the connecting frame 11, and the other end of the driving component 30 can be connected to the transmission mechanism to drive the connecting frame 11 to rotate. At the same time, the end of the driving component 30 inserted into the socket can be provided with a fixing hole, and the positioning component 40 can extend from the positioning hole 115 to the fixing hole to lock and fix the driving component 30, thereby improving the connection stability between the driving component 30 and the driving connection part 112.

[0062] With this configuration, the drive unit 30 can drive the connecting bracket 11 to rotate around the axis of the insertion hole, causing each massage head to rotate as well. Simultaneously, as each massage head rotates around the axis of the insertion hole, when it presses against the massage area, it can also rotate around the axis of its connecting shaft, allowing it to roll relative to the massage area and thus preventing scratches to the skin.

[0063] Understandably, the drive component 30 can be configured as a drive shaft, and the positioning component 40 can be configured as a fastening bolt. The fastening bolt can be concealed within the positioning hole 115 to avoid scratching the skin and to improve the aesthetics of the massage device 1.

[0064] See Figures 4 to 6Taking at least two connecting shafts, including a first connecting shaft 12 and a second connecting shaft 13, as an example, the massage assembly 20 may include a first massage head 21 located on the first connecting shaft 12 and a second massage head 22 located on the second connecting shaft 13. In the depth direction along the mounting groove 111, the dimension d1 by which the first massage head 21 protrudes from the bottom wall of the mounting groove 111 is not less than the dimension d2 by which the second massage head 22 protrudes from the bottom wall of the mounting groove 111.

[0065] This design, due to the different heights at which the first massage head 21 and the second massage head 22 protrude from the bottom wall of the mounting groove 111, allows the first massage head 21 and the second massage head 22 to exert different pressures on the user's massage area, thereby enriching the user's massage experience. Understandably, when the protrusion dimension d1 of the first massage head 21 is greater than the protrusion dimension d2 of the second massage head 22, the massage force exerted by the first massage head 21 on the massage area is greater than that exerted by the second massage head 22.

[0066] In some embodiments, the massage surface 24 of at least one of the first massage head 21 and the second massage head 22 may also be provided with uneven ribs to enrich the massage effect on the massage area.

[0067] In some embodiments, the insertion hole of the drive connection portion 112 may be arranged along the depth direction of the mounting groove 111, the axial direction of the first connecting shaft 12 and the second connecting shaft 13 may be set to be the same, and the axial direction of the first connecting shaft 12 and the second connecting shaft 13 may be perpendicular to the axial direction of the insertion hole.

[0068] See Figures 4 to 6 In some embodiments, the massage device 1 further includes a limiting component 50 located between the connecting shaft and the massage head, the limiting component 50 being used to limit the axial movement distance of the massage head along the connecting shaft. This configuration allows the limiting component 50 to restrict the sliding of the massage head relative to the massage area, thereby preventing the massage head from chafing the massage area.

[0069] As an example, the limiting component 50 includes a bushing 51 sleeved on the connecting shaft and a fastener 52 connecting the bushing 51 and the connecting shaft. The massage head has a limiting hole 27 that mates with the bushing 51, and the bushing 51 abuts against the limiting hole 27. The bushing 51 includes a first connecting portion 511 and a second connecting portion 512 sequentially connected along the axial direction of the connecting shaft. The outer diameter of the first connecting portion 511 is smaller than the outer diameter of the second connecting portion 512. The massage head has a first connecting hole that mates with the first connecting portion 511 and a second connecting hole that mates with the second connecting portion 512. The fastener 52 can be connected between the second connecting portion of the bushing 51 and the connecting shaft, thereby enabling the limiting component 50 to limit each massage head along the axial direction of the connecting shaft.

[0070] In addition, the bushing 51 is located between the massage head and the connecting shaft, and can also be used to reduce the friction between the massage head and the connecting shaft.

[0071] Understandably, fastener 52 includes fastening screws, fastening bolts, etc., and this application does not limit them.

[0072] See you later Figure 1 , Figure 4 and Figure 5 In some embodiments, to facilitate the setting of the hollow structure 23 of the massage head, the massage head includes a first connecting surface 25 and a second connecting surface 26 spaced apart along the axial direction of the connecting shaft, and a massage surface 24 connected between the first connecting surface 25 and the second connecting surface 26, and the hollow structure 23 is connected between the first connecting surface 25 and the second connecting surface 26.

[0073] The massage surface 24 of the massage head is used to contact the user's massage area to transmit massage force. The massage surface 24 can be arranged circumferentially along the connecting shaft, and also spaced apart from the connecting shaft radially, giving the massage head a thickness along the radial direction of the connecting shaft. A perforated structure 23 is disposed between the connecting shaft and the massage surface 24 to form pores in the wall thickness of the massage head. These pores reduce the structural rigidity of the massage head and increase its elastic deformation space.

[0074] Thus, during the use of the massage head, when the massage surface 24 comes into contact with and presses against the user's massage area, the massage surface 24 can deform radially along the connecting shaft to press the hollow structure 23. In turn, the elastic deformation of the hollow structure 23 can buffer the pressure pain of the massage surface 24 on the user's massage area, increase the softness of the massage head's force on the massage area, and thus improve the user's massage comfort.

[0075] Furthermore, in some embodiments, the massage head is typically designed to be larger to cover more massage areas on the user's body, thereby improving massage efficiency and effectiveness. However, increasing the volume of the solid massage head in related technologies results in a larger volume and thicker walls, making it less susceptible to compression and deformation. This leads to a more pronounced hardness felt by the user, resulting in poorer massage comfort. However, when increasing the volume of the massage head in this application, the hollow structure 23 can limit the increase in hardness caused by the increased volume. The hollow structure 23 removes some material from the massage head to reduce its hardness, and also increases the elastic deformation space through the formed pores, allowing for greater deformation and softness. Thus, the massage head provided in this application can maintain good softness even with increased volume, thanks to the hollow structure 23, thus ensuring massage comfort for the user.

[0076] Understandably, the hollow structure 23 of the massage head in this application can also reduce the weight of the massage head, thereby reducing the weight of the massage device 1, so as to improve the user's comfort when wearing the massage device 1 and reduce the burden.

[0077] Understandably, the hollow structure 23 of the massage head in this application can also save the materials required for manufacturing the massage head, thereby saving material costs.

[0078] Understandably, the hollow structure 23 of the massage head in this application can also reduce the drive load of the transmission mechanism.

[0079] In some embodiments, the hollow structure 23 includes an airbag structure, a honeycomb structure, etc., and this application is not limited thereto. Understandably, an airbag structure can achieve flexible support by utilizing the deformation of compressible gas within a closed air cavity. A honeycomb structure can achieve flexible support by utilizing multiple regularly arranged polygonal structures.

[0080] See Figure 4 and Figure 5 In some embodiments, to facilitate the provision of a hollow structure 23 on the massage head, the hollow structure 23 extends along the axial direction of the connecting shaft, and the hollow structure 23 can penetrate at least one of the first connecting surface 25 and the second connecting surface 26.

[0081] This design allows the perforated structure 23 to be directly machined from the first connecting surface 25 and / or the second connecting surface 26 without compromising the structural integrity of the massage surface 24, thus avoiding affecting the contact area between the massage surface 24 and the massage area. Simultaneously, the perforated structure 23 extends axially along the connecting shaft, enabling it to deform radially along the connecting shaft, thereby increasing the deformation space of the massage surface 24 and facilitating a more flexible contact when the massage surface 24 is pressed against the massage area.

[0082] As an example, Figure 5 The hollow structure 23 shown passes through the first connecting surface 25 and the second connecting surface 26 in sequence. This arrangement ensures that the hollow structure 23 is present at various points along the axial direction of the connecting shaft between the massage surface 24 and the connecting shaft. This means that regardless of where the massage surface 24 is pressed against the massage area, the hollow structure 23 increases the elastic deformation space of the massage surface 24, allowing it to provide a gentle massage force to the massage area from all points, thus preventing uneven massage force.

[0083] See Figure 1 and Figure 7 In some embodiments, the perforated structure 23 includes at least two hole layers spaced apart from each other in the radial direction along the connecting axis, with each hole layer having a different hole shape and / or hole size.

[0084] This design allows the massage head to form multiple superimposed elastic deformation spaces between the connecting shaft and the massage surface 24, increasing the softness of the massage surface 24. Simultaneously, the spacing between adjacent perforated layers allows the massage head's solid structure to be supported between these layers, providing stable support and thus creating a combination of soft and firm massage force to the massage area, preventing the massage force from being too soft or too hard. Understandably, the hollow structure 23 can have 2, 3, or 4 perforated layers, etc., and this application does not impose any limitation.

[0085] See Figure 7 In some embodiments, the hole size of each hole layer increases sequentially along the direction from the connecting shaft toward the massage surface 24.

[0086] This configuration allows the massage head to form a hardness gradient between the connecting shaft and the massage surface 24. The massage surface 24 serves as the outer layer of the massage head, and the connecting shaft as the inner layer. When the size of the mating hole near the outer layer is larger than that near the inner layer, it indicates that the elastic deformation space of the hole layer near the outer layer is greater than that near the inner layer. This causes the structural strength of the massage head to gradually decrease from the inside out, meaning the hardness of the massage head gradually decreases from the inside out, creating a hardness gradient with a hard middle and a gradually softening outer layer.

[0087] Thus, the massage surface 24 of the massage head, being closer to the outer layer, has better elasticity. When the massage surface 24 comes into contact with the massage area, it can generate a soft and comfortable massage force, reducing the user's pain. At the same time, the connecting shaft of the massage head can be used to connect with the drive shaft of the massage device 1. The connecting shaft is located inside the massage head, and can better transmit the torque of the drive component 30 through the structural strength of the massage head, so as to drive the massage head to rotate relative to the massage device 1.

[0088] As an example, at least two perforated layers include a first perforated layer 231 near the massage surface 24 and a second perforated layer 232 near the connecting shaft. The first perforated layer 231 has at least two first mating holes spaced apart circumferentially along the connecting shaft, and the second perforated layer 232 has at least two second mating holes spaced apart circumferentially along the connecting shaft. The size of the first mating holes can be set larger than the size of the second mating holes. In this way, the first perforated layer 231 is softer than the second perforated layer 232, and can easily deform to buffer the massage force on the massage area and reduce the pain caused by the massage surface 24 applying force to the massage area. At the same time, the second perforated layer 232 can be used to connect the drive shaft of the massage device 1 to transmit torque.

[0089] Understandably, each pore layer includes at least one of circular pores, elliptical pores, square pores, polygonal pores, irregular pores, and spiral pores.

[0090] In some embodiments, to facilitate the setting of the first mating hole and the second mating hole, the first mating hole and the second mating hole can be set to the same shape.

[0091] As an example, see Figure 7 The first and second mating holes can each be configured as ellipses. Specifically, the major axis of the ellipse can be set along the circumference of the connecting shaft, and the minor axis along the radial direction of the connecting shaft. Of course, in other embodiments, the major axis of the ellipse can also be set along the radial direction of the connecting shaft, and the minor axis along the circumference of the connecting shaft; this application does not impose any limitations. It is understood that the elliptical dimension located in the first hole layer 231 can be set larger than the elliptical dimension located in the second hole layer 232. Of course, in other embodiments, the elliptical dimension located in the first hole layer 231 can be set no larger than the elliptical dimension located in the second hole layer 232; this application does not impose any limitations.

[0092] Of course, in other embodiments, the first mating hole and the second mating hole may also be configured as hexagons. As an example, one diagonal of the hexagon may be arranged circumferentially along the connecting shaft, and / or, two opposite sides of the hexagon may be arranged radially perpendicular to the connecting shaft. Understandably, the size of the hexagon located in the first hole layer 231 may be larger than the size of the hexagon located in the second hole layer 232. Of course, in other embodiments, the size of the hexagon located in the first hole layer 231 may be no larger than the size of the hexagon located in the second hole layer 232; this application does not impose any limitations on this.

[0093] In other embodiments, at least one of the at least two hole layers may have at least two types of mating holes alternately distributed circumferentially along the connecting axis, each mating hole having a different shape and / or size. As an example, the first hole layer 231 may have a first mating hole and a third mating hole spaced apart circumferentially along the connecting axis. The first mating hole may be elliptical, and the third mating hole may be hexagonal. The first hole layer 231 may alternately have the first and third mating holes. The second hole layer 232 may have a second mating hole and a fourth mating hole spaced apart circumferentially along the connecting axis. The second mating hole may be square, and the fourth mating hole may be hexagonal. The second hole layer 232 may alternately have the second and fourth mating holes. Thus, the first hole layer 231 and the second hole layer 232 can provide different elastic effects by providing a mixture of holes.

[0094] In some embodiments, the massage head may be configured as spherical, wheel-shaped, ellipsoidal, etc., and this application does not impose any restrictions.

[0095] In some embodiments, to reduce the pain caused by the massage head on the massaged area, the massage head may be made of soft rubber. Furthermore, the soft rubber material also helps to prevent scratching the skin of the massaged area.

[0096] Understandably, soft rubber materials include silicone, rubber, latex, polyurethane (PU), thermoplastic polyurethane elastomer (TPU), ethylene-vinyl acetate copolymer (EVA), etc., and this application does not impose any restrictions.

[0097] In some embodiments, a protective cover may be provided on the massage head to prevent excessive wear. Furthermore, the protective cover may be made of a skin-friendly material to improve the tactile experience when the massage head contacts the massaged area, thereby enhancing the massage effect.

[0098] See you later Figure 5 In some embodiments, the axial direction of the holes in each hole layer is parallel to the axial direction of the connecting shaft. In other embodiments, the axial direction of the holes in each hole layer may also be inclined relative to the axial direction of the connecting shaft; this application does not impose any limitations.
