Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically relating to an ear acupressure massager. Background Technology

[0002] Auricular therapy is an important branch of traditional Chinese medicine physiotherapy. Its core theory is that there is a corresponding reflex relationship between the auricle and the internal organs and systems of the human body. Stimulating specific auricular points can achieve the effect of regulating the body. Early auricular stimulation relied on manual operation by physicians, such as pressing with spring probes or needling with acupuncture needles. However, manual methods depend on professional experience and are difficult to standardize and routinely implement at home. With the initial development of medical equipment, the earliest acupoint detection electrode device appeared in 1955. Since then, auricular acupoint related equipment has gradually developed from simple detection to a combination of "detection + treatment," laying the theoretical and applied foundation for the subsequent development of auricular massage equipment. The "pressing-kneading" techniques of manual massage have also become the core simulation target of this bionic therapeutic device.

[0003] The maturity of multidisciplinary technologies provides core support for the research and development of bionic finger-type therapeutic devices. In the field of mechanical transmission, the miniaturization and adjustability of micro DC brushless motors and eccentric vibration motors allow the device to achieve complex movements such as rotation and vibration of the massage head within a limited space. The high strength and lightweight characteristics of carbon fiber materials also meet the precise transmission requirements of gears and drive shafts. In terms of bionics and materials technology, the application of materials such as medical-grade silicone with controllable Shore hardness and slow-rebound memory foam can simulate the touch of human fingers, while the adaptive structure of the built-in spring solves the problem of fitting irregular curved surfaces. In terms of temperature control technology, PTC heating elements combined with PID temperature control algorithms can achieve precise constant temperature control, while Bluetooth communication and mobile APP control technology allow users to flexibly adjust massage modes and parameters. In addition, the high capacity and fast charging technology of 18650 lithium batteries ensure the portability of the device and meet the needs of home and travel scenarios.

[0004] However, the core shortcomings of existing traditional ear acupressure massage devices can be summarized into the following five categories: 1. Single massage mode. Existing devices generally adopt a single action mode of "vibration + electrical stimulation," lacking the combined mechanical pressing, rotation, and kneading movements that simulate professional TCM massage. They can only provide superficial stimulation to ear acupoints and cannot achieve deep acupoint conditioning, making it difficult to achieve the expected effects of TCM ear acupressure therapy. At the same time, electrical stimulation can easily cause stinging discomfort in some people, limiting the applicable population. 2. Poor ear acupoint fit accuracy and insufficient positioning precision. Traditional devices rely on the passive fit of the overall structure to the ear, without designing an adaptive structure for the irregular curved surface of the ear, and ignoring individual ear shape differences. During the massage, problems such as "false pressure" and "misplaced pressure" are prone to occur, making it impossible to accurately act on the target ear acupoint area. Some devices lack acupoint limiting functions, and the movement trajectory of the massage head is uncontrollable, further reducing the targeted nature of the physiotherapy. 3. Unreasonable wearing structure and poor long-term user experience. Mainstream head-mounted devices use a single inverted U-shaped support structure, concentrating the device's weight on the soft tissue of the ear. The clamping force is difficult to control precisely, and prolonged wear can easily cause pressure and pain. Furthermore, changes in head posture (looking down, looking up, turning the head) can easily cause the device to shift or fall off, compromising the stability of the massage process and failing to meet the needs of long-term home care. 4. Fixed functional design, lacking personalized adaptation capabilities. Most existing devices only support a single massage mode, lacking zoned massage functions. They cannot provide targeted ear acupoint stimulation for specific user health needs (such as sleep regulation and stress relief). They also lack a constant temperature control module, which can cause cold stimulation when the ear contacts the device in low-temperature environments, further reducing user comfort. 5. Lack of hygienic design, posing a risk of cross-infection. The massage components of traditional devices are mostly fixed and non-removable structures, easily accumulating dirt, sweat, and bacteria after long-term use, making thorough cleaning difficult. In shared settings (such as nursing homes and traditional Chinese medicine clinics), this can easily lead to cross-infection risks, failing to meet the hygienic use standards for medical devices.

[0005] Therefore, there is an urgent need to design an ear acupressure massager to solve the above problems. Summary of the Invention

[0006] To address the problems of existing traditional ear acupressure massage devices, such as limited massage modes, poor ear acupressure fit accuracy, insufficient positioning precision, unreasonable wearing structure, poor long-term user experience, rigid functional design, lack of personalized adaptation capabilities, and lack of hygiene design, posing a risk of cross-infection, this invention provides an ear acupressure massager.

[0017] The beneficial effects of this invention are: This invention discloses an ear acupressure massager, and compared with the prior art, the improvement of this invention lies in: (1) The ear acupoint massager designed in this invention integrates full ear acupoint massage, a driving mechanism, and an ear acupoint massage auxiliary mechanism on the ear bag, constructing a composite massage mechanical system of "pressing-rotating-vibrating". It accurately simulates the finger massage techniques of professional TCM doctors, enhances the depth of ear acupoint stimulation and physiotherapy effect, and abandons the single electrical stimulation mode, improving the comfort of use. Moreover, the ear acupoint massager of this invention has a lightweight structure and multiple functions. Users can easily wear it and move freely. It is easy to operate and suitable for home or daily use. Under the action of the driving mechanism, the ear acupoint massage head slides on the ear bag in an elliptical trajectory, moving in accordance with the shape of the ear, so that all acupoints of the ear can be massaged. At the same time, through the ear acupoint massage auxiliary mechanism, the ear acupoint massage head can achieve adaptive contact with the ear, avoiding excessive pressure causing discomfort or insufficient pressure causing insufficient massage effect. In addition, the ear acupoint massage auxiliary mechanism also automatically applies essential oil to the ear acupoint massage head during massage, improving the effect of ear acupoint massage, further promoting blood circulation in the ear, and facilitating patient rehabilitation treatment.

[0018] (2) The ear acupoint massage head designed in this invention is detachable and can be easily replaced according to the usage time, or replaced by one person at a time, to ensure hygiene and safety during use, as well as convenient replacement and maintenance in case of malfunction. In this invention, the ear acupoint massage head is a rolling massage head, which performs rolling massage when massaging the ear, avoiding the discomfort or even damage to the skin of the ear caused by traditional contact friction massage under long-term massage.

[0019] (3) The present invention integrates the drive mechanism into the ear bag, saving space and reducing the overall size of the device, making it more convenient and easy to wear. When used for massage, the drive mechanism can drive the ear acupoint massage head to slide back and forth around the whole ear, and the movement trajectory is elliptical, which fits the contour of the human ear better, so that it can systematically cover the main acupoint areas of the ear, avoiding the limitations of traditional fixed-point massage and improving the comprehensiveness and effect of massage.

[0020] (4) This invention designs an auricular acupressure massage auxiliary mechanism. Through the coordinated use of the oiling component and the oiling component, the auricular acupressure massage auxiliary mechanism plays a flexible connection and adjustment role between the massage head and the drive mechanism. This allows the massage ball to adaptively adjust the contact pressure according to the actual shape and contour of the user's ear, ensuring that the massage force is fully applied to the acupoints while reducing pressure discomfort. This improves the patient's massage comfort while ensuring the massage effect. The auricular acupressure massage auxiliary mechanism also has the function of applying essential oil to the auricular acupressure massage head. Essential oil care can be carried out simultaneously during the massage, promoting the penetration of effective ingredients through the skin. It has the dual effects of aromatherapy and acupoint stimulation, further unblocking the meridians, relieving fatigue, and improving the user experience and health care effect.

[0029] Furthermore, the accompanying drawings are not drawn to a 1:1 scale, and the relative dimensions of the components are shown in the drawings only as examples and not necessarily to actual scale. Example:

[0030] See attached document Figures 1-18 The ear acupressure massager shown includes a headband 1, two ear pads 2, an ear acupressure massage head 3, a drive mechanism 4, and an ear acupressure massage auxiliary mechanism 5. The two ear pads 2 are fixedly connected to both ends of the headband 1. The ear acupressure massage head 3 is slidably disposed on the ear pads 2 and can slide along the elliptical trajectory of the elliptical groove 201 on the inner side of the ear pads 2 to massage the main acupoints of the ear.

[0031] The drive mechanism 4 is located inside the ear bag 2 and is connected to the ear acupoint massage head 3. It is used to drive the ear acupoint massage head 3 to slide along an elliptical trajectory in the slide groove 201 to achieve reciprocating sliding around the whole ear and perform whole ear massage.

[0032] The ear acupressure massage auxiliary mechanism 5 is located inside the ear bag 2 and connected between the ear acupressure massage head 3 and the drive mechanism 4. This allows the ear acupressure massage head 3 to make adaptive contact with the ear and to apply essential oil to the ear acupressure massage head 3 during operation. It enables adaptive adjustment of the contact angle and pressure according to the actual shape and contour of the user's ear, ensuring that the massage force is fully applied to the acupoints while reducing pressure discomfort and improving the user experience. At the same time, essential oil care is applied simultaneously during the massage process to promote the penetration of effective ingredients through the skin. This combines the dual effects of aromatherapy and acupoint stimulation, further unblocking the meridians, relieving fatigue, and enhancing the user experience and health benefits.

[0033] In this embodiment, refer to the appendix Figure 3As shown, headband 1 is a dual support structure consisting of an inverted U-shaped main bracket and an O-shaped fixing band. Headband 1 is made of high-elasticity medical-grade AB material in one piece. The elastic coefficient is optimized through mechanical simulation to ensure that the clamping force on both sides is controlled within the range of 2.5-3.0N (which meets the pressure threshold of human ear soft tissue and avoids pressure pain). It is suitable for most people with a head circumference of 54-62cm. The weight of headband 1 is evenly distributed to the top of the head and the forehead area, which reduces the pressure on the ears by more than 60%, achieving comfortable wear for 8 hours, while preventing the device from shifting when the head posture changes.

[0034] Specifically, the headband 1 includes an O-shaped fixing band 101 and an integrally formed connecting portion 102 connected to both sides of the O-shaped fixing band 101. The O-shaped fixing band 101, in conjunction with the connecting portion 102, evenly distributes the weight of the device to the top of the head and the forehead area. Simultaneously, anti-slip textures are provided on the inner side of the O-shaped band to prevent the device from shifting when the head posture changes, ensuring a stable fit between the massager and the ear acupoints during the massage process. In this embodiment, the diameter of the O-shaped fixing band 101 is 8-10 cm, and its thickness is 0.8 cm.

[0035] See attached document Figure 2 As shown, the inner side of the ear cup 2 is provided with a memory foam ring, which protects the user's ear and improves comfort when the ear cup 2 fits the user's ear. The inner wall of the ear cup 2 has an elliptical groove 201 that communicates with its inner cavity, and the groove 201 is a T-shaped groove, which facilitates the sliding and locking of the ear acupoint massage head 3 and the sliding limit of the housing 501 in the ear acupoint massage auxiliary mechanism 5.

[0036] The 201 groove structure is highly adapted to the ear contour, allowing the massage head to massage key acupoints throughout the ear.

[0037] In this embodiment, refer to the appendix Figures 4-6 As shown, the drive mechanism 4 is located in the cavity outside the ear bag 2, and a detachable outer cover is also provided on the outside to seal the cavity outside the ear bag 2. The drive mechanism 4 includes a micro motor 401, a gear set 402, and a rotating arm 403. The micro motor 401 is fixedly mounted on the inner wall of the ear bag 2 and is used to drive the gear set 402 and the rotating arm 403 to move. The gear set 402 is connected to the output end of the micro motor 401. One end of the rotating arm 403 is connected to the ear acupressure head 3, and the other end is connected to the gear set 402. The gear set 402 and the rotating arm 403 cooperate to drive the ear acupressure head 3 to slide back and forth in an elliptical trajectory inside the ear bag 2.

[0038] Among them, the micro motor 401 is a DC brushless motor with adjustable speed, which can be selected with a voltage of 12V and an adjustable speed range of 50-150rpm; the gear set 402 and the rotating arm 403 are made of carbon fiber, which has the characteristics of being lightweight, high-strength, high-modulus, high-temperature resistant, impact resistant, chemical corrosion resistant, and having a low coefficient of expansion.

[0039] The micro motor 401 is started, which drives the rotating arm 403 to rotate at an angular velocity of 15° / s through the gear set 402. At the same time, the gear set 404 (reduction ratio 1:5) transmits the power of the micro motor 401 to the rotating arm 403, so that the rotating arm 403 rotates synchronously at an angular velocity of 3° / s, realizing the reciprocating sliding in an elliptical trajectory within the ear bag 2.

[0040] Specifically, the gear set 402 includes a first gear 4021, a second gear 4022, a third gear 4023, and a fixing plate 4024. The first gear 4021 is fixedly connected to the micro motor 401 by bolts; the second gear 4022 meshes with the first gear 4021 and is rotatably connected to the fixing plate 4024 by bearings; the third gear 4023 meshes with the second gear 4022 and is rotatably connected to the rotating arm 403 by bearings; the fixing plate 4024 is rotatably connected to the first gear 4021, the second gear 4022, and the third gear 4023 by bearings.

[0041] The reduction ratio of the first gear 4021 to the second gear 4022 is 1:1, and the reduction ratio of the third gear 4023 to the second gear 4022 is 1:5. Through the reduction of the gear set 402, the rotation speed of the rotating arm 403 is slowed down, which meets the rotation speed requirements of the ear acupoint massage head 3 during massage.

[0042] In use, the micro motor 401 drives the first gear 4021 to rotate, the first gear 4021 drives the second gear 4022 to rotate, the second gear 4022 drives the third gear 4023 to rotate, the fixing plate 4024 ensures the stability of the three gears during rotation, the third gear 4023 drives the rotating arm 403 to rotate, and at the same time the rotating arm 403 changes angle relative to the third gear 4023, thereby fitting the elliptical groove 201 on the ear bag 2 to realize full ear key acupoint massage.

[0043] In the embodiments of this application, reference is made to the appendix. Figures 7-10 As shown, the ear acupressure massage head 3 includes a massage ball support 301 and a massage ball 302. The massage ball support 301 is made of lightweight, corrosion-resistant and high-temperature resistant carbon fiber material. It is slidably inserted into the groove 201 on the ear bag 2 and is detachably connected to the ear acupressure massage auxiliary mechanism 5. The massage ball 302 is rotatably embedded in the massage ball support 301.

[0044] For details, please refer to the appendix. Figure 8 and Figure 10As shown, the massage ball support 301 includes a support body 3011, a threaded sleeve 3012, and an oil delivery sleeve 3013. The threaded sleeve 3012 is fixedly mounted on the support body 3011 and is threadedly connected to the ear acupressure massage auxiliary mechanism 5, achieving a detachable connection. The oil delivery sleeve 3013 is fixedly connected to the support body 3011 and communicates with the inner cavity of the support body 3011. The oil delivery sleeve 3013 is also concentrically arranged with the threaded sleeve 3012. The oil delivery sleeve 3013 is used in conjunction with the ear acupressure massage auxiliary mechanism 5 to apply essential oil to the massage ball 302 through the support body 3011.

[0045] The threaded sleeve 3012 is detachably connected to the auricular acupressure auxiliary mechanism 5, enabling the detachable connection of the massage ball bracket 301. This facilitates later maintenance and convenient replacement. In clinical practice, it can achieve the goal of one replacement per person, ensuring hygiene and safety during use.

[0046] In the embodiments of this application, reference is made to the appendix. Figure 8 and Figure 11-15 As shown, the ear acupressure massage auxiliary mechanism 5 includes a housing 501, an oiling component 502, and an elastic element 503. The housing 501 is fitted into a sliding groove 201 and can slide within the groove 201. The oiling component 502 is movably disposed within the housing 501, with one end detachably connected to a threaded sleeve 3012 and communicating with an oil delivery sleeve 3013. While detachably connected to the threaded sleeve 3012, it can also introduce essential oil into the oil delivery sleeve 3013, allowing the essential oil to enter the support body 3011 from the oil delivery sleeve 3013, thereby applying essential oil to the massage ball 302. The other end of the oiling component 502 is slidably inserted into an annular groove 5011 within the housing 501 and can slide within the annular groove 5011. The elastic element 503 is fitted onto the oiling component 502, with both ends abutting against the inner wall of the housing 501, enabling adaptive adjustment of the contact force between the massage ball 302 and the ear. The elastic element 503 is a spring or a spring sheet.

[0047] When the massage ball 302 is placed on the ear, the ear exerts a counterforce on the massage ball 302, which in turn pushes the oiling component 502 to slide outward from the ear cup 2 along the annular groove 5011 within the housing 501. Due to the limiting effect of the groove 201 on the housing 501, the end of the oiling component 502 slides outward from the ear cup 2 within the annular groove 5011, thereby allowing the essential oil in the oiling component 502 to enter the oil delivery sleeve 3013 and finally flow into the support body 3011, thus applying essential oil to the massage ball 302. The massage ball 302 automatically applies essential oil and massages the ear by rolling and moving on the ear.

[0048] At the same time, when the oiling component 502 is pushed to move within the housing 501, the elastic element 503 is also squeezed, so that the massage ball 302 can make adaptive contact with the ear and adjust the intensity of its contact with the ear as needed.

[0049] Specifically, the oiling assembly 502 includes a threaded rod 5021, a drive disc 5022, and an oil delivery component. The threaded rod 5021 is screwed to the threaded sleeve 3012 for a detachable connection. The drive disc 5022 is movably disposed within the housing 501 and is fixedly connected to the threaded rod 5021, while also abutting against one end of the elastic element 503. One end of the oil delivery component passes through the drive disc 5022 and communicates with the oil delivery sleeve 3013, while the other end is slidably inserted into the annular groove 5011.

[0050] When the support body 3011 presses the drive disc 5022 through the threaded rod 5021, the drive disc 5022 will press and compress the elastic element 503, and at the same time, it will press the oil delivery component to slide in the annular groove 5011, so that the inner cavity of the oil delivery component of the housing 501 becomes smaller, and the essential oil enters the oil delivery sleeve 3013 from the cavity inside the oil delivery component.

[0051] Furthermore, the oil delivery component includes an oil storage sleeve 5023 and an installation tube 5024. One end of the oil storage sleeve 5023 passes through the drive disc 5022 and communicates with the oil delivery sleeve 3013, while the other end is movably inserted into the annular groove 5011 and can slide in the annular groove 5011. The installation tube 5024 is concentrically fixedly inserted into the oil storage sleeve 5023 to add essential oil to the oil storage sleeve 5023. A vibration motor 5025 is also detachably inserted into the end of the installation tube 5024, which drives the oiling assembly 502 to cause the massage ball 302 to vibrate and massage.

[0052] In this embodiment, the oil storage sleeve 5023 is a hollow cylindrical structure with one end open. Its closed end is provided with multiple oil outlets 5023A that communicate with its inner cavity. The oil outlets 5023A are fixedly connected to the oil delivery sleeve 3013 through the drive disc 5022. When the inner cavity of the oil storage sleeve 5023 is squeezed, the essential oil enters the oil delivery sleeve 3013 from the oil outlets 5023A and finally flows into the massage ball 302 through the support body 3011.

[0053] One end of the mounting tube 5024 is integrally equipped with a mounting head 5024A for mounting the vibration motor 5025. The mounting tube 5024 also has a T-shaped oiling groove 5024B inside, which is connected to the outside of the mounting tube 5024. The end of the oiling groove 5024B is connected to the bottom of the mounting head 5024A. By adding essential oil to the mounting head 5024A, the essential oil flows from the bottom of the mounting head 5024A into the oiling groove 5024B, and then flows out from the oiling groove 5024B into the oil storage sleeve 5023, thus filling the oil storage sleeve 5023. Finally, the vibration motor 5025 is installed in the mounting head 5024A, thereby blocking one end of the oiling groove 5024B and preventing the essential oil from flowing out.

[0054] When the massage ball 302 is placed on the ear, the ear exerts a counterforce on the massage ball 302, which in turn pushes the support body 3011 to move outward towards the ear cup 2. The outward movement of the support body 3011 causes the drive disc 5022 to move within the housing 501. While the drive disc 5022 is compressing the elastic element 503, it also drives the oil storage sleeve 5023 to slide within the annular groove 5011. As a result, under the compression of the housing 501, the essential oil in the oil storage sleeve 5023 is pushed from the oil outlet 5023A into the oil delivery sleeve 3013, and finally flows into the inner cavity of the support body 3011 to apply essential oil to the massage ball 302.

[0055] See attached document Figures 16-18 As shown, in order to further compress the essential oil in the oil storage sleeve 5023, this embodiment also provides a compression assembly, which includes two first racks 6, two gears 601, a piston 602, and two second racks 603. The two first racks 6 are symmetrically structured, movably inserted into the housing 501, and fixedly connected to the drive disc 5022. The two gears 601 are symmetrically sleeved on the mounting head 5024A through the bracket 6011, and the two gears 601 are rotatably connected to the bracket 6011 respectively, and mesh with the two first racks 6 respectively. The two second racks 603 are movably inserted into the oil storage sleeve 5023 from the inner wall of the mounting tube 5024, and are fixedly connected to the piston 602 set in the oil storage sleeve 5023, and mesh with the two gears 601 respectively.

[0056] When the drive disc 5022 moves, it synchronously drives the rack 6 to move relative to the housing 501, which in turn causes the rack 6 to drive the two gears 601 to rotate. The rotation of the two gears 601 drives the two racks 603 to move in opposite directions, which in turn pushes the piston 602 to squeeze the essential oil in the inner cavity of the oil storage sleeve 5023, thereby squeezing the essential oil into the bracket body 3011, thus achieving the application of essential oil to the massage ball 302.

[0057] In this embodiment, a thermostatic control box is also provided on the earcup 2 to heat and control the temperature of the memory foam on the earcup 2. This thermostatic control box uses a PTC heating element (5W power) and a temperature sensor (accuracy ±0.3℃) in conjunction. By adjusting the heating power in real time, the surface temperature of the memory foam is stabilized at 36-38℃, simulating the temperature of a human hand, thus improving massage comfort and preventing the ears from getting cold in low-temperature environments. The heating principle and circuit control of this thermostatic control box are existing technologies, and this application does not make any improvements to them.

[0058] In this embodiment, six limit switches are embedded in the groove 201 on the earpiece 2. These switches work in conjunction with the control system to control the movement trajectory of the ear acupoint massage head 3. Specifically, the control system can control whether the ear acupoint massage head 3 travels its full or partial stroke within the groove 201. A full stroke provides a full ear massage, while a partial stroke focuses on specific acupoints on the ear. Multiple modes can be set via the system, each corresponding to a specific massage area. In this application, both the control system and the limit switches are existing technologies, and no improvements have been made to them.

[0059] In practical use, the ear acupressure massager in this embodiment can also be equipped with a music playback function and a heating function. The music playback function can be implemented by embedding a mini music playback module inside the ear bag 2, which can play songs for the user during massage to provide a massage experience. At the same time, a heating wire module is also wrapped inside the ear bag 2 to heat the ear bag 2, so that the user can heat the ear while massaging, thereby improving the massage effect.

[0060] The working principle of the ear acupressure massager of the present invention is as follows: When using it, first put the massager on your head, so that the O-ring fixing hoop 101 is located at the top of your head, then gently place the ear bag 2 on your ear and make the ear acupressure massage head 3 contact with your ear. When the massage ball 302 is attached to the ear, the ear gives the massage ball 302 a reverse force, which pushes the support body 3011 to move outward towards the ear bag 2. The outward movement of the support body 3011 drives the drive disc 5022 to move within the housing 501. While the drive disc 5022 is squeezing the elastic element 503, it also drives the oil storage sleeve 5023 to slide within the annular groove 5011. Thus, under the squeezing action of the housing 501, the essential oil in the oil storage sleeve 5023 enters the oil delivery sleeve 3013 from the oil outlet 5023A and finally flows into the inner cavity of the support body 3011 to apply essential oil to the massage ball 302.

[0061] The compression elastic element 503 ensures that the ear acupressure massage head 3 makes adaptive contact with the ear, achieving a close fit to the ear acupressure points without any pressure gaps. At the same time, it assists the ear acupressure massage head 3 in circulating and squeezing the drive disc 5022, facilitating the flow of essential oils.

[0062] When the drive disc 5022 moves, it synchronously drives the rack 6 to move relative to the housing 501, which in turn causes the rack 6 to drive the two gears 601 to rotate. The rotation of the two gears 601 drives the two racks 603 to move in opposite directions, which in turn pushes the piston 602 to squeeze the essential oil in the inner cavity of the oil storage sleeve 5023, thereby squeezing the essential oil into the bracket body 3011, thus achieving the application of essential oil to the massage ball 302.

[0063] When the vibration motor 5025 is turned on, the vibration motor 5025 drives the mounting tube 5024, the oil storage sleeve 5023, the drive disc 5022, and the threaded rod 5021 to vibrate up and down along the annular groove 5011 inside the housing 501, thereby realizing synchronous vibration massage when the massage ball 302 slides and massages.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
