Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a rotating magnetic device and massage chair that integrates magnetic therapy and physical massage functions. It is suitable for daily physical therapy and health care scenarios such as relieving muscle pain and improving blood circulation in the neck, shoulders, back, limbs, and other parts of the human body. It belongs to the cross-technical field of dynamic magnetic field therapy equipment and massage equipment in category 09-05-01 of the "Medical Device Classification Catalog". Background Technology

[0002] With the development of the biomedical industry and physiotherapy and healthcare technologies, magnetotherapy, as a gentle and non-invasive physical therapy method, has been widely used in clinical rehabilitation and home healthcare. Rotating magnetic devices, as the core type of magnetotherapy equipment, use drive components to rotate permanent magnets, forming a dynamically changing rotating magnetic field. Utilizing the biological effects of the magnetic field on human tissues (such as improving local microcirculation, relieving muscle spasms, and promoting the excretion of metabolic waste), they provide adjunctive treatment for symptoms such as chronic pain and fatigue syndrome.

[0003] The core function of existing magnetic rotating devices is focused on the effect of magnetic therapy. Their structure usually only includes permanent magnets, rotating drive components and supporting and fixing structures. When working, the permanent magnets rotate at a fixed height and act on the human body only through the magnetic field. This has the defect of single function, that is, the simple magnetic field stimulation feels mild but lacks the direct soothing effect of physical pressure. It has limited effect on relieving problems such as muscle stiffness and nodules. Summary of the Invention

[0004] Therefore, in view of the above problems, the present invention proposes a rotating magnetic device and a massage chair with rotating magnetic device for daily physical therapy and health care of the human body's waist, back, limbs and other parts.

[0005] This invention is achieved through the following technical solution:

[0006] A magnetic rotating device includes a magnetic rotating housing, a plurality of permanent magnets disposed within the magnetic rotating housing, and a rotation drive device for driving the magnetic rotating housing to rotate. The magnetic rotating housing is provided with a plurality of lifting ends, and the permanent magnets are disposed within the lifting ends. The magnetic rotating housing is provided with a main shaft, which is rotatable relative to the magnetic rotating housing and has one end extending out of the magnetic rotating housing. A swashplate is fixed and inclinedly disposed on the main shaft, and a swing plate is rotatably connected to the swashplate. A connecting rod is hinged at both ends to the swing plate and the lifting ends, respectively.

[0007] The magnetic housing has several limiting channels for each lifting end to slide individually and for limiting the movement trajectory of the lifting end. One end of the lifting end is allowed to extend out of the magnetic housing when it rises.

[0008] As a further improvement of the present invention, a cylindrical roller bearing for the swashplate is provided between the swashplate and the inclined plate, wherein the inner ring of the cylindrical roller bearing for the swashplate is fixedly connected to the swashplate, and the outer ring is rotatably engaged with the inclined plate.

[0009] When the magnetic housing rotates, it drives the swashplate to rotate. Because the swashplate is tilted and fixed, the swashplate undulates adaptively along the inclined surface of the swashplate through the cylindrical roller bearing of the swashplate, and then swings around its own axis.

[0010] As a further improvement of the present invention, the swivel plate has a top groove formed inwardly from its surface at a position away from the end face of the inclined plate and at its center.

[0011] The magnetic housing is provided with a push shaft, which is configured to be coaxial with the main shaft, with its end facing the push groove, and the end of the push shaft is provided with a steel ball suitable for the push groove.

[0012] As a further improvement of the present invention, a mounting platform is provided inside the magnetic housing, the abutting shaft is slidably disposed on the mounting platform, and an elastic element is provided between the abutting shaft and the mounting platform. The elastic element acts on the abutting shaft to drive the lower end of the abutting shaft to maintain abutting engagement with the steel ball.

[0013] As a further improvement of the present invention, the side wall of the lifting end is provided with a sealing ring suitable for fitting against the inner wall of the limiting channel.

[0014] As a further improvement of the present invention, the connecting rod is provided with rotating ball heads at both ends, and the swing plate and the lifting end are both provided with ball head connecting seats, and the ball head connecting seats are provided with connecting grooves suitable for connecting the rotating ball heads.

[0015] As a further improvement of the present invention, the number of ball joint connectors provided on the oscillating plate is the same as the number of limiting channels, and the ball joint connectors on the oscillating plate are arranged in a circular array on the oscillating plate.

[0016] Based on the same concept, the present invention also discloses a massage chair, including an armrest, the armrest being provided with a receiving portion, the receiving portion being provided with a rotating magnetic device as described above, and the receiving portion being provided with a first driving device for driving the rotating magnetic device to slide along the length direction of the receiving portion.

[0017] As a further improvement of the present invention, the first driving device includes: a transmission seat fixedly disposed at one end of the main shaft outside the magnetic housing; a lead screw disposed in the receiving part; the lead screw passes through the transmission seat and is connected to the transmission seat in a driving connection; and a drive motor is disposed in the receiving part and is connected to the lead screw in a driving connection to drive the lead screw to rotate.

[0018] The receiving portion is provided with a guide rod, which passes through the transmission seat to limit the rotation of the transmission seat when the transmission seat slides.

[0019] As a further improvement of the present invention, the rotation drive device includes a transmission tooth disposed on the side wall of the magnetic housing, a tooth row inside the receiving portion, the tooth row extending in the length direction of the receiving portion, the tooth row meshing with the transmission tooth to drive the magnetic housing to rotate when the magnetic device slides along the length direction of the receiving portion.

[0020] By adopting the aforementioned technical solution, the beneficial effects of the present invention are:

[0021] 1. In this invention, a rotating drive device drives the rotating magnetic shell to rotate, which in turn drives each lifting end to rotate. The lifting end is equipped with a permanent magnet, thereby achieving synchronous rotation of the permanent magnet with the rotating magnetic shell, thus forming a dynamically changing rotating magnetic field. This allows the use of the biological effects of the magnetic field on human tissues (such as improving local microcirculation, relieving muscle spasms, and promoting the excretion of metabolic waste) to achieve adjunctive treatment for symptoms such as chronic pain and fatigue syndrome.

[0022] 2. At the same time, since the main shaft is fixed to the external structure, when the magnetic housing rotates, the main shaft remains stationary, causing the tilt angle of the swashplate to change relative to the magnetic housing. That is, the swashplate rotates relative to the swashplate. At this time, the swashplate transmits the rotation to the lifting end through the connecting rod, causing the lifting end to reciprocate up and down along the axial direction inside the magnetic housing. In this way, the permanent magnet can also adjust its up and down position while rotating with the magnetic housing, thereby changing the magnetic field distribution state of the permanent magnet in space and forming a dynamically adjusted rotating magnetic field.

[0023] 3. The rotating magnetic device in this invention can not only perform magnetic therapy on the human body, but also simulate massage. The rotating magnetic field continuously acts on acupoints and lesion areas of the human body. Through the dynamic changes in the strength and direction of the magnetic field, it regulates the magnitude and direction of the biocurrent in the body, affecting cell membrane permeability, ion distribution, and magnetic moment orientation of biological macromolecules, thereby changing the physiological and biochemical processes of tissue cells and achieving effects such as reducing swelling and pain, reducing inflammation and calming the nerves. At the same time, the periodic pressing of the lifting end directly acts on muscles and subcutaneous tissues, promoting local capillary dilation through mechanical stimulation, accelerating blood flow and lymphatic circulation, helping to clear metabolic products, and relieving muscle adhesions and stiffness. The two physical methods work at different levels and complement each other, thereby significantly improving the intervention effect on symptoms such as chronic soft tissue injury and joint pain.

[0030] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0031] Example 1:

[0032] refer to Figure 1 , Figure 2This embodiment discloses a magnetic rotating device, including a magnetic rotating housing 3, a plurality of permanent magnets 101 disposed within the magnetic rotating housing 3, and a rotation drive device for driving the magnetic rotating housing 3 to rotate (which can be a motor connected to the magnetic rotating housing 3, or other power source capable of driving the magnetic rotating housing 3 to rotate, which will not be described in detail here). A plurality of lifting ends 9 are disposed within the magnetic rotating housing, and the permanent magnets 101 are disposed within the lifting ends 9. A main shaft 4 is disposed within the magnetic rotating housing 3, the main shaft 4 being rotatable relative to the magnetic rotating housing 3 and having one end extending out of the magnetic rotating housing 3. A swashplate 5 is fixedly and inclinedly disposed on the main shaft 4, and a swing plate 6 is rotatably connected to the swashplate 5. The system includes connecting rods 8, hinged at both ends to the swing plate 6 and the lifting end 9 respectively (connecting rods 8 to different eccentric positions of the swing plate 6); wherein, the main shaft 4 is coaxially arranged with the magnetic housing 3, the magnetic housing 3 has a cylindrical structure, the main shaft 4 can rotate relative to the magnetic housing 3 around its own axis, and the axis of the swashplate 5 has an angle with the axis of the main shaft 4, so that the swashplate 5 is inclined relative to the axis of the main shaft 4; when the swing plate 6 moves with the magnetic housing 3, the swing plate 6 is acted upon by the swashplate 5, and makes a periodic undulating swaying motion along its circumference during rotation; in addition, one end of the main shaft 4 passes through the magnetic housing 3 and is fixedly connected to an external structure (fixed to an external bracket). To ensure the main shaft 4 remains stationary while the magnetic housing 3 rotates, the specific working principle of this embodiment is as follows: the rotation drive device drives the magnetic housing 3 to rotate, and the magnetic housing 3 drives each of the lifting ends 9 to rotate. A permanent magnet 101 is installed inside each lifting end 9, thus achieving synchronous rotation of the permanent magnet 101 with the magnetic housing 3, thereby forming a dynamically changing rotating magnetic field. This utilizes the biological effects of the magnetic field on human tissues (such as improving local microcirculation, relieving muscle spasms, and promoting the excretion of metabolic waste) to achieve adjunctive treatment for symptoms such as chronic pain and fatigue syndrome. Simultaneously, since the main shaft 4 is fixed to the external structure, when the magnetic housing 3 rotates, the main shaft 4 remains stationary, allowing the swashplate to... The tilt angle of plate 5 changes relative to the magnetic housing 3, that is, the swing plate 6 rotates relative to the slant plate 5. At this time, the swing plate 6 is transmitted to the lifting end 9 through the connecting rod 8, which drives the lifting end 9 to reciprocate up and down along the axis within the magnetic housing 3. In this way, the permanent magnet 101 can also adjust its up and down position while rotating with the magnetic housing 3, thereby changing the magnetic field distribution state of the permanent magnet 101 in space and forming a dynamically adjusted rotating magnetic field. This ensures that the magnetic field strength of the same part alternates in real time with the massage rhythm (press-reset), and there is no "constant stimulation". As a result, the human tissue is always in a "dynamic response" state and will not produce "adaptation", thus improving the continuous intervention effect of magnetic therapy.

[0033] The magnetic housing 3 has several limiting channels 10 for each lifting end 9 to slide independently and for limiting the movement trajectory of the lifting end 9. One end of the lifting end 9 is allowed to extend outside the magnetic housing 3 when it rises. Specifically, the limiting channels 10 are arranged in a circular array on the magnetic housing 3. When in use, this device is close to the human body. During the lifting process, the lifting end 9 can also generate a certain frequency of mechanical pressure on the surface of the human body. This mechanical stimulation can form a synergistic effect with the rotating magnetic field, further enhancing the physical intervention effect on local tissues. Of course... The lifting end head 9 is arc-shaped to improve the fit and comfort of contact with the human body during massage, avoiding unnecessary friction or pressure on the skin during the pressing process. Furthermore, due to the periodic oscillation of the swing plate 6, the lifting movements of each lifting end head 9 can form an alternating pressing rhythm according to the difference in the position of the connecting rod 8, realizing comprehensive and continuous massage of different areas of the human body. This design can also press and massage different areas of the human body, ensuring that multiple parts of the body can receive sufficient pressure stimulation, realizing continuous massage, effectively relieving tension and fatigue of arm muscles, and improving the comfort and effectiveness of the massage.

[0034] In this embodiment, the rotating magnetic device can not only perform magnetic therapy on the human body, but also simulate massage. The rotating magnetic field continuously acts on acupoints and lesion areas of the human body. Through the dynamic changes in the strength and direction of the magnetic field, it regulates the magnitude and direction of the biocurrent in the body, affecting cell membrane permeability, ion distribution, and magnetic moment orientation of biological macromolecules, thereby changing the physiological and biochemical processes of tissue cells and achieving effects such as reducing swelling and pain, reducing inflammation and calming the nerves. At the same time, the periodic pressing of the lifting end 9 directly acts on muscles and subcutaneous tissues, promoting local capillary dilation through mechanical stimulation, accelerating blood flow and lymphatic circulation, helping to clear metabolic products, and relieving muscle adhesions and stiffness. The two physical methods work at different levels and complement each other, thereby significantly improving the intervention effect on symptoms such as chronic soft tissue injury and joint pain.

[0035] It should be noted that a cylindrical roller bearing 7 is provided between the swashplate 6 and the swashplate 5. The inner ring of the cylindrical roller bearing 7 is fixedly connected to the swashplate 6, and the outer ring is rotatably engaged with the swashplate 5. When the magnetic housing 3 rotates, it drives the swashplate 6 to rotate. Because the swashplate 5 is tilted and fixed, the swashplate 6 undulates adaptively along the inclined surface of the swashplate through the cylindrical roller bearing 7, and then swings around its own axis. Through the action of the cylindrical roller bearing 7, the swashplate 6 can rotate and undulate adaptively relative to the axis of the main shaft 4 without driving the swashplate 5 and the main shaft 4 to rotate together. Its working principle is as follows: because the swashplate 5 is tilted, during the rotation of the swashplate 6, the distance between any end of the side of the swashplate 6 and the limiting channel 10 changes periodically. Specifically, this change is similar to the process of gradually transitioning from the "lowest point" to the "highest point" of the inclined surface, and then cyclically switching back from the "highest point" to the "lowest point". As the oscillating plate 6 continues to rotate, this periodic change will repeat continuously. This distance change is transformed into the periodic oscillation of the oscillating plate 6 around the main axis 4 by the pushing force between the swashplate 5 and the oscillating plate 6 (the oscillation plane has an oscillation angle with the axis of the main axis 4, similar to a "seesaw" motion). At this time, one end of the connecting rod 8 is hinged to the eccentric position (non-center) of the oscillating plate 6 through the rotating ball head 11 (described below), and the other end passes through the limiting channel 10 at the upper end of the magnetic housing 3, and is hinged to the lifting end head 9 through the rotating ball head 11 (described below). When the oscillating plate 6... When rotating relative to the main shaft 4, the trajectory of each eccentric position is an arc. Through the length constraint of the connecting rod 8, the arc trajectory is transformed into the linear reciprocating motion (i.e., "lifting") of the lifting end head 9 along the limiting channel 10. That is, when the swing plate 6 swings to one side, the connecting rod 8 pushes the lifting end head 9 to rise along the limiting channel 10, partially extending outside the limiting channel 10, and applying pressure to the human body placed on the upper side of the rotating magnetic housing 3; when the swing plate 6 swings to the other side, the connecting rod 8 pulls the lifting end head 9 to descend along the limiting channel 10, retracting into the limiting channel 10, completing one massage cycle.

[0036] A mounting platform 15 is provided inside the magnetic housing 3. The abutment shaft 13 is slidably disposed on the mounting platform 15. An elastic element 16, which is a pre-compressed compression spring, is provided between the abutment shaft 13 and the mounting platform 15. The elastic element 16 acts on the abutment shaft 13 to drive the lower end of the abutment shaft 13 to maintain abutment engagement with the steel ball 14. When the swing disk 6 rotates with the main shaft 4, the inner wall of the abutment groove 12 will continuously contact the steel ball 14 and generate relative sliding. The elastic reset element always applies an elastic force toward the abutment shaft 13 to the swing disk 6 to ensure that the steel ball 14 and the abutment groove are in contact. The inner wall of 12 fits tightly to prevent the swing plate 6 from shaking or getting stuck during movement. This structural design not only provides stable support and guidance for the swing of the swing plate 6, but also reduces the rigid collision between the swing plate 6 and the abutment shaft 13 through the buffering effect of the elastic reset component, reducing noise and wear during device operation, thereby extending the service life of the overall structure. At the same time, the setting of steel ball 14 transforms the sliding friction between the abutment shaft 13 and the abutment groove 12 into rolling friction, effectively reducing the movement resistance, making the swing of the swing plate 6 smoother and more stable, and further improving the accuracy and reliability of the lifting action of the massage end head 9.

[0037] In this embodiment, the included angle (the angle between the axis of the swashplate 5 and the axis of the main shaft 4) is 5°-25°. This angle design allows the swashplate 6 to generate an appropriate swing amplitude during rotation, thereby ensuring that the massage head 9 has sufficient pressure and stroke variation during lifting and lowering, making the massage effect closer to the comfortable feeling of manual massage. It can also be preset according to actual needs, so that the undulation and swing amplitude of the swashplate can be precisely controlled, thereby adjusting the reciprocating stroke of the massage head to adapt to the personalized requirements of different users for massage intensity and range.

[0038] The side wall of the lifting end 9 is provided with a sealing ring 17 suitable for fitting against the inner wall of the limiting channel 10. The sealing ring 17 is made of an elastic material, such as silicone or rubber, which can fit tightly against the inner wall of the limiting channel 10, preventing dust and impurities from entering the internal mechanical structure of the magnetic housing 3, thereby protecting the components and reducing wear. In addition, this design helps to ensure that the movement of the lifting end 9 is more stable and quiet, avoiding leakage or increased frictional resistance during the lifting process of the lifting end 9, and ensuring the continuity and accuracy of the alternating pressing action. At the same time, the high wear resistance of the sealing ring 17 extends the overall service life, reduces maintenance requirements, and enables the massage device to maintain high efficiency in long-term use.

[0039] The connecting rod 8 is equipped with rotating ball heads 11 at both ends. Both the swing plate 6 and the lifting end 9 are provided with ball head connecting seats 18. The ball head connecting seats 18 have connecting grooves suitable for connecting the rotating ball heads 11. The rotating ball heads 11 and the connecting grooves are in spherical contact fit. This structural design allows the connecting rod 8 to rotate flexibly within a multi-angle range, enabling the lifting end 9 to adaptively lift and adjust its angle as the swing plate 6 rotates. The inner wall of the connecting groove of the ball head connecting seat 18 is smoothed during production, reducing frictional resistance and noise during movement of the rotating ball heads 11. It also avoids the jamming phenomenon common in traditional hinge structures, improving the smoothness of the massage movements. Furthermore, an elastic retaining ring is provided at the opening of the connecting groove to axially limit the rotating ball heads 11, preventing them from falling out of the connecting groove. This ensures the stability and reliability of the connection between the connecting rod 8 and the swing plate 6 and lifting end 9, ensuring that the massage effect is not affected by loosening during long-term, high-frequency use.

[0040] The limiting channels 10 are provided in multiple numbers, an even number, specifically 6 in this embodiment, arranged in a circular array on the magnetic housing 3. The number of ball joints 18 provided on the swing plate 6 is the same as the number of limiting channels 10. The ball joints 18 on the swing plate 6 are arranged in a circular array on the swing plate 6. Correspondingly, in this embodiment, the number of connecting rods 8 and lifting ends 9 are also provided in 6. With multiple lifting ends 9 arranged in a circular array, they can massage the user from different directions, avoiding the massage blind spots that exist in traditional single-point or linear massage. As the swing plate 6 swings periodically, multiple lifting ends 9 can contact and act on the human body surface in sequence, forming a continuous and rhythmic interlaced pressing effect, thereby improving the comprehensiveness and comfort of the massage.

[0041] The rotating magnetic device in this embodiment is applicable to various scenarios such as massage chairs, massage beds, and rehabilitation therapy equipment. In massage chair applications, it can be integrated into the backrest, seat cushion, or leg support area. Through its adaptive design with the chair structure, it can achieve precise massage of areas such as the shoulders, neck, lower back, buttocks, and thighs. In massage bed scenarios, it can be installed in different areas of the bed surface. Combined with the bed's lifting or tilting functions, it can meet the user's multi-position massage needs for the back, waist, and legs while lying down. In rehabilitation therapy equipment, its stable mechanical transmission and controllable massage intensity can assist in muscle relaxation, promote blood circulation, and provide strong support for rehabilitation training.

[0042] Example 2:

[0043] refer to Figures 1 to 4The present invention discloses a massage chair, including an armrest 1, wherein the armrest 1 is provided with a receiving part 2 for accommodating an arm, a rotating magnetic device is provided in the receiving part 2, and a first driving device is provided on the receiving part 2 for driving the rotating magnetic device to slide along the length direction of the receiving part 2.

[0044] The magnetic rotating device includes a magnetic rotating housing 3, a plurality of permanent magnets 101 disposed within the magnetic rotating housing 3, and a rotation drive device for driving the magnetic rotating housing 3 to rotate. A plurality of lifting ends 9 are disposed within the magnetic rotating housing, and the permanent magnets 101 are disposed within the lifting ends 9. A main shaft 4 is disposed within the magnetic rotating housing 3, and the main shaft 4 is rotatable relative to the magnetic rotating housing 3 with one end extending out of the magnetic rotating housing 3. A swashplate 5 is fixedly and inclinedly disposed on the main shaft 4, and a swing plate 6 is rotatably connected to the swashplate 5, with both ends hinged to the swing plate 6 and... The lifting end 9 is hinged to a connecting rod 8 (connecting rod 8 to different eccentric positions of the swing plate 6); wherein, the main shaft 4 is coaxially arranged with the magnetic housing 3, the magnetic housing 3 has a cylindrical structure, the main shaft 4 can rotate relative to the magnetic housing 3 around its own axis, and the axis of the swashplate 5 has an angle with the axis of the main shaft 4, so that the swashplate 5 is inclined relative to the axis of the main shaft 4; when the swing plate 6 moves with the magnetic housing 3, the swing plate 6 is acted upon by the swashplate 5, and makes a periodic undulating swaying motion along its circumference during rotation; in addition, the main shaft 4 extends out The rotating magnetic housing 3 is fixedly connected to the handrail 1 at one end. The specific working principle of this embodiment is as follows: the rotating drive device drives the rotating magnetic housing 3 to rotate, and the rotating magnetic housing 3 drives each of the lifting ends 9 to rotate. A permanent magnet 101 is installed inside each lifting end 9, thus achieving synchronous rotation of the permanent magnet 101 with the rotating magnetic housing 3, thereby forming a dynamically changing rotating magnetic field. This utilizes the biological effects of the magnetic field on human tissues (such as improving local microcirculation, relieving muscle spasms, and promoting the excretion of metabolic waste) to achieve adjunctive treatment for symptoms such as chronic pain and fatigue syndrome. When the main shaft 4 is fixed to the external structure, the main shaft 4 remains stationary when the magnetic housing 3 rotates, causing the tilt angle of the swashplate 5 to change relative to the magnetic housing 3. That is, the swing plate 6 rotates relative to the swashplate 5. At this time, the swing plate 6 transmits to the lifting end 9 through the connecting rod 8, causing the lifting end 9 to reciprocate up and down along the axial direction inside the magnetic housing 3. In this way, the permanent magnet 101 can also adjust its up and down position while rotating with the magnetic housing 3, thereby changing the magnetic field distribution state of the permanent magnet 101 in space and forming a dynamically adjusted rotating magnetic field.

[0045] The magnetic housing 3 has several limiting channels 10 for each lifting end 9 to slide individually and for limiting the movement trajectory of the lifting end 9. One end of the lifting end 9 extends out of the magnetic housing 3 when it rises. Specifically, the limiting channels 10 are arranged in a circular array on the magnetic housing 3. When in use, this device is close to the human body. During the lifting process, the lifting end 9 can also generate a certain frequency of mechanical pressure on the human body surface. This mechanical stimulation can form a synergistic effect with the rotating magnetic field, further enhancing the physical intervention effect on local tissues. Of course, the lifting end 9 can also generate a certain frequency of mechanical pressure on the human body surface. The lowering head 9 is arc-shaped to improve the fit and comfort of contact with the body during massage, avoiding unnecessary friction or pressure on the skin during the pressing process. Furthermore, due to the periodic oscillation of the swing plate 6, the lifting and lowering movements of each lifting head 9 can form an alternating pressing rhythm according to the difference in the position of the connecting rod 8, realizing comprehensive and continuous massage of different areas of the body. This design can also press and massage different areas of the body, ensuring that multiple parts of the body can receive sufficient pressure stimulation, realizing continuous massage, effectively relieving tension and fatigue of arm muscles, and improving the comfort and effectiveness of the massage.

[0046] Therefore, the rotating magnetic device in this embodiment can not only perform magnetic therapy on the human body, but also simulate massage. The rotating magnetic field continuously acts on acupoints and lesion areas of the human body. Through the dynamic changes in the strength and direction of the magnetic field, it regulates the magnitude and direction of the biocurrent in the body, affecting cell membrane permeability, ion distribution, and the magnetic moment orientation of biological macromolecules, thereby changing the physiological and biochemical processes of tissue cells and achieving effects such as reducing swelling and pain, and reducing inflammation and calming the nerves. At the same time, the periodic pressing of the lifting end 9 directly acts on muscles and subcutaneous tissue, promoting local capillary dilation through mechanical stimulation and accelerating blood flow and lymphatic circulation. It helps to clear metabolic waste products while relieving muscle adhesions and stiffness. The two physical methods work at different levels and complement each other (mechanical pressure can physically loosen muscle adhesions and fascial tension, reducing the mechanical tension of local tissues. Histological studies have shown that soft tissues in a relaxed state have lower electrical impedance and higher permeability, which creates more favorable conditions for the penetration of rotating magnetic fields, allowing magnetic field energy to act more deeply on the deep muscles and bones, thereby expanding the effective range and depth of magnetic therapy), thus significantly improving the intervention effect on symptoms such as chronic soft tissue injury and joint pain.

[0047] It should be noted that a cylindrical roller bearing 7 is provided between the swashplate 6 and the swashplate 5. The inner ring of the cylindrical roller bearing 7 is fixedly connected to the swashplate 6, and the outer ring is rotatably engaged with the swashplate 5. When the magnetic housing 3 rotates, it drives the swashplate 6 to rotate. Because the swashplate 5 is tilted and fixed, the swashplate 6 undulates adaptively along the inclined surface of the swashplate through the cylindrical roller bearing 7, and then swings around its own axis. Through the action of the cylindrical roller bearing 7, the swashplate 6 can rotate and undulate adaptively relative to the axis of the main shaft 4 without driving the swashplate 5 and the main shaft 4 to rotate together. Its working principle is as follows: because the swashplate 5 is tilted, during the rotation of the swashplate 6, the distance between any end of the side of the swashplate 6 and the limiting channel 10 changes periodically. Specifically, this change is similar to the process of gradually transitioning from the "lowest point" to the "highest point" of the inclined surface, and then cyclically switching back from the "highest point" to the "lowest point". As the oscillating plate 6 continues to rotate, this periodic change will repeat continuously. This distance change is transformed into the periodic oscillation of the oscillating plate 6 around the main axis 4 by the pushing force between the swashplate 5 and the oscillating plate 6 (the oscillation plane has an oscillation angle with the axis of the main axis 4, similar to a "seesaw" motion). At this time, one end of the connecting rod 8 is hinged to the eccentric position (non-center) of the oscillating plate 6 through the rotating ball head 11 (described below), and the other end passes through the limiting channel 10 at the upper end of the magnetic housing 3, and is hinged to the lifting end head 9 through the rotating ball head 11 (described below). When the oscillating plate 6... When rotating relative to the main shaft 4, the trajectory of each eccentric position is an arc. Through the length constraint of the connecting rod 8, the arc trajectory is transformed into the linear reciprocating motion (i.e., "lifting") of the lifting end head 9 along the limiting channel 10. That is, when the swing plate 6 swings to one side, the connecting rod 8 pushes the lifting end head 9 to rise along the limiting channel 10, partially extending outside the limiting channel 10, and applying pressure to the human body placed on the upper side of the rotating magnetic housing 3; when the swing plate 6 swings to the other side, the connecting rod 8 pulls the lifting end head 9 to descend along the limiting channel 10, retracting into the limiting channel 10, completing one massage cycle.

[0048] A mounting platform 15 is provided inside the magnetic housing 3. The abutment shaft 13 is slidably disposed on the mounting platform 15. An elastic element 16, which is a pre-compressed compression spring, is provided between the abutment shaft 13 and the mounting platform 15. The elastic element 16 acts on the abutment shaft 13 to drive the lower end of the abutment shaft 13 to maintain abutment engagement with the steel ball 14. When the swing disk 6 rotates with the main shaft 4, the inner wall of the abutment groove 12 will continuously contact the steel ball 14 and generate relative sliding. The elastic reset element always applies an elastic force toward the abutment shaft 13 to the swing disk 6 to ensure that the steel ball 14 and the abutment groove are in contact. The inner wall of 12 fits tightly to prevent the swing plate 6 from shaking or getting stuck during movement. This structural design not only provides stable support and guidance for the swing of the swing plate 6, but also reduces the rigid collision between the swing plate 6 and the abutment shaft 13 through the buffering effect of the elastic reset component, reducing noise and wear during device operation, thereby extending the service life of the overall structure. At the same time, the setting of steel ball 14 transforms the sliding friction between the abutment shaft 13 and the abutment groove 12 into rolling friction, effectively reducing the movement resistance, making the swing of the swing plate 6 smoother and more stable, and further improving the accuracy and reliability of the lifting action of the massage end head 9.

[0049] In this embodiment, the included angle (the angle between the axis of the swashplate 5 and the axis of the main shaft 4) is 5°-25°. This angle design allows the swashplate 6 to generate an appropriate swing amplitude during rotation, thereby ensuring that the massage head 9 has sufficient pressure and stroke variation during lifting and lowering, making the massage effect closer to the comfortable feeling of manual massage. It can also be preset according to actual needs, so that the undulation and swing amplitude of the swashplate can be precisely controlled, thereby adjusting the reciprocating stroke of the massage head to adapt to the personalized requirements of different users for massage intensity and range.

[0050] The side wall of the lifting end 9 is provided with a sealing ring 17 suitable for fitting against the inner wall of the limiting channel 10. The sealing ring 17 is made of an elastic material, such as silicone or rubber, which can fit tightly against the inner wall of the limiting channel 10, preventing dust and impurities from entering the internal mechanical structure of the magnetic housing 3, thereby protecting the components and reducing wear. In addition, this design helps to ensure that the movement of the lifting end 9 is more stable and quiet, avoiding leakage or increased frictional resistance during the lifting process of the lifting end 9, and ensuring the continuity and accuracy of the alternating pressing action. At the same time, the high wear resistance of the sealing ring 17 extends the overall service life, reduces maintenance requirements, and enables the massage device to maintain high efficiency in long-term use.

[0051] The connecting rod 8 is equipped with rotating ball heads 11 at both ends. Both the swing plate 6 and the lifting end 9 are provided with ball head connecting seats 18. The ball head connecting seats 18 have connecting grooves suitable for connecting the rotating ball heads 11. The rotating ball heads 11 and the connecting grooves are in spherical contact fit. This structural design allows the connecting rod 8 to rotate flexibly within a multi-angle range, enabling the lifting end 9 to adaptively lift and adjust its angle as the swing plate 6 rotates. The inner wall of the connecting groove of the ball head connecting seat 18 is smoothed during production, reducing frictional resistance and noise during movement of the rotating ball heads 11. It also avoids the jamming phenomenon common in traditional hinge structures, improving the smoothness of the massage movements. Furthermore, an elastic retaining ring is provided at the opening of the connecting groove to axially limit the rotating ball heads 11, preventing them from falling out of the connecting groove. This ensures the stability and reliability of the connection between the connecting rod 8 and the swing plate 6 and lifting end 9, ensuring that the massage effect is not affected by loosening during long-term, high-frequency use.

[0052] The limiting channels 10 are provided in multiple numbers, an even number, specifically 6 in this embodiment, arranged in a circular array on the magnetic housing 3. The number of ball joints 18 provided on the swing plate 6 is the same as the number of limiting channels 10. The ball joints 18 on the swing plate 6 are arranged in a circular array on the swing plate 6. Correspondingly, in this embodiment, the number of connecting rods 8 and lifting ends 9 are also provided in 6. With multiple lifting ends 9 arranged in a circular array, they can massage the user from different directions, avoiding the massage blind spots that exist in traditional single-point or linear massage. As the swing plate 6 swings periodically, multiple lifting ends 9 can contact and act on the human body surface in sequence, forming a continuous and rhythmic interlaced pressing effect, thereby improving the comprehensiveness and comfort of the massage.

[0053] In this embodiment, the first driving device includes: a transmission seat 19 fixedly connected to one end of the main shaft 4 outside the magnetic housing 3; a lead screw 20 disposed in the receiving part 2; the lead screw 20 passing through the transmission seat 19 and being threadedly connected to the transmission seat 19; and a drive motor 21 disposed in the receiving part 2, which is driven by the lead screw 20 to rotate. Using the drive motor 21 as a power source, it first starts and outputs rotational torque. The output shaft of the drive motor 21 forms a transmission connection with the lead screw 20 (the specific connection method, such as gears or couplings, is not detailed, but the core is torque transmission). Therefore, the rotation of the drive motor 21... The rotational motion drives the lead screw 20 to rotate within the receiving portion 2. The lead screw 20 passes through the transmission seat 19 and forms a transmission connection with the transmission seat 19. When the lead screw 20 rotates, it drives the transmission seat 19 to move along the length direction of the receiving portion 2 on the lead screw 20. Through the transmission connection between the lead screw 20 and the transmission seat 19, the rotational motion of the motor is converted into the linear motion of the transmission seat 19 along the length direction of the receiving portion 2, thereby driving the rotary magnetic device to slide smoothly. This lead screw 20 transmission method has the characteristics of high transmission accuracy and rapid response, which can ensure that it moves stably according to the preset trajectory, avoids jamming or deviation during the sliding process, and improves driving efficiency and operational reliability.

[0054] The receiving part 2 is provided with a guide rod 201, which passes through the transmission seat 19 to limit the rotation of the transmission seat 19 when the transmission seat 19 slides.

[0055] In this embodiment, the rotation drive device includes a transmission tooth 23 disposed on the side wall of the magnetic housing 3 and a tooth row 22 on the inner side of the receiving portion 2. The tooth row 22 extends along the length direction of the receiving portion 2 and meshes with the transmission tooth 23 to drive the magnetic housing 3 to rotate when the magnetic device slides along the length direction of the receiving portion 2. The rotation drive device ingeniously converts the sliding motion of the magnetic device along the length direction of the receiving portion 2 directly into the rotational motion of the magnetic housing 3. This gear-meshing transmission method requires no additional power source. The main shaft 4 can be driven to rotate by the sliding motion of the rotating magnetic device itself, achieving efficient linkage of motion. This simple structure not only reduces the number of parts in the housing 2 and saves installation space, but also reduces the overall complexity of the device, making it easier to produce, assemble, and maintain. It also helps to control manufacturing costs. Of course, in actual use, it is necessary to control the transmission ratio between the gear row 22 and the transmission gear 23 to control the rotation speed of the rotating magnetic housing 3 and the lifting frequency of the lifting end 9, so as to ensure that the dynamic changes of the rotating magnetic field match the rhythm of mechanical pressing, thereby achieving the best synergistic therapeutic effect. This can be achieved by those skilled in the art simply by calculating conventional gear parameters (such as module, number of teeth, pressure angle, etc.), and will not be elaborated here.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions above are merely illustrative of the principles of the present invention. Various changes and modifications can be made to the present invention without departing from its spirit and scope. All such changes and modifications fall within the scope of the present invention as claimed, which is defined by the appended claims and their equivalents.
