Description

Technical Field

[0001] This invention relates to the field of physiotherapy equipment technology, specifically to a thermotherapy adaptive positioning device equipped with a multi-link synchronous drive structure. Background Technology

[0002] Medical constant-temperature hot compresses and thermotherapy rehabilitation of the core meridians and soft tissue areas of the human body can effectively accelerate local microcirculation and the excretion of waste metabolites. Currently, the temperature-controlled hot compress heat transfer mechanism of conventional rehabilitation physiotherapy equipment generally adopts the method of padding a resistance heating wire or a positive temperature coefficient heating plate inside the leather sleeve.

[0003] However, existing technologies face the following technical bottlenecks in physiotherapy applications: First, the heat-conducting layer of the hot compress is very easy to detach from the air, resulting in serious heat loss during physiotherapy. When the body changes posture, air gaps are easily created in the waist area, and the rigid heating element cannot achieve isobaric tracking and fit, resulting in a significant decrease in the depth of heat penetration.

[0004] Secondly, the heating wire introduced into the dynamic reciprocating module poses a high risk of leakage. If the external power supply wire is connected to the repeatedly swinging mechanism, the wire is very easy to break under fatigue reciprocating conditions, causing a short circuit and burn accident.

[0005] Third, traditional solid heat therapy contact surfaces lack heat transfer buffering, have poor temperature control and uniform heat distribution, and release heat linearly. Before the deep soft tissue reaches the therapeutic temperature threshold, the skin surface already has a noticeable burning sensation.

[0006] The urgent technical problem to be solved in the industry is: how to design a device that can adaptably and closely fit the lumbar spine curve with a heat-conducting adhesive surface, and convert pure mechanical energy into flexible constant temperature physiotherapy energy in a non-contact manner without the power supply wires connected to the rotating reciprocating component. Summary of the Invention

[0007] To address the safety issues of existing technologies, such as the heat-conducting contact surface easily detaching from the surface and the external heating wire of the dynamic reciprocating heating module being prone to breakage and electrical leakage, this invention designs a thermotherapy adaptive positioning device equipped with a multi-link synchronous drive structure. The multi-link mechanism allows the positioning heat-conducting seat and the posture-following frame to move synchronously. Combined with a non-contact constant-temperature heat transfer mechanism, this device improves the fit of the heat compress to the lower back and enhances the overall effect of constant-temperature therapy without requiring additional external heating wires.

[0008] To achieve the above objectives, the present invention provides the following technical solution: A thermotherapy adaptive positioning device equipped with a multi-link synchronous drive structure includes a chassis, a fixed frame, and a support frame; a load-bearing base plate fixedly connected to the top of the support frame; a posture follower frame hinged to one end of the load-bearing base plate; and a leg support plate hinged to the other end of the load-bearing base plate. The chassis is provided with a swing mechanism for driving the support frame to reciprocate. The device also includes: two hydraulic rods hinged between the load-bearing base plate and the support frame; a positioning heat-conducting seat movably connected to the inner side of the posture follower frame; and a multi-link mechanism disposed at the bottom of the load-bearing base plate, which, in conjunction with the rotation of the posture follower frame, drives the leg support plate to rotate and the positioning heat-conducting seat to move upward along an arc-shaped trajectory and arch upward. The inner side of the positioning heat-conducting seat is equipped with a thermal therapy heat transfer mechanism. It utilizes the circulating flow of the insulating liquid heat transfer medium inside the heat transfer rotating seat and the flexible heat-equalizing contact body to simultaneously achieve flexible isobaric constant temperature heat therapy and water flow white noise for deep sleep aid.

[0009] Preferably, the multi-link mechanism includes a first support rod hinged to the bottom of the support base plate, a second support rod rotatably connected to one end of the first support rod, and connecting rod brackets fixedly connected to both ends of the second support rod. The ends of the two connecting rod brackets away from the second support rod are hinged to the attitude follower frame. A second connecting rod is hinged to the other end of the first support rod, and the end of the second connecting rod away from the first support rod is hinged to the leg support plate. A third support rod is rotatably connected to the middle of the two connecting rod brackets, and the ends of the two third support rods away from the connecting rod brackets are hinged to the positioning heat-conducting seat. Movable shafts are fixedly connected to both ends of the positioning heat-conducting seat. An arc-shaped guide groove is provided on the inner wall of the attitude follower frame to slide with the movable shaft.

[0010] In the above solution, when the user adjusts the backrest angle, the hydraulic rod drives the movable frame to rotate backward, the connecting rod bracket drives the first support rod to swing, and the second connecting rod synchronously drives the leg support to unfold upward. At the same time, the third support rod pulls the movable shaft of the positioning heat conduction seat to slide along the arc-shaped guide groove, so that the positioning heat conduction seat moves upward and arches appropriately. By adjusting the backrest angle, the leg support lifting and lumbar support adaptive adjustment can be completed simultaneously, without the need to operate multiple control switches separately, simplifying the process of switching from sitting to lying down. The trajectory of the arc-shaped guide groove matches the changes in the curvature of the human lumbar spine, which can fill the gap in the waist when lying down in real time, avoiding fatigue caused by the waist being unsupported.

[0011] Preferably, the thermotherapy heat transfer mechanism includes two parallel rotating shafts, each rotatably connected to the inner side of the positioning heat-conducting seat. Several heat-transfer rotating seats are fixedly connected to each of the two rotating shafts, equidistantly distributed along the axis of the shafts. The heat-transfer rotating seats on the two rotating shafts are staggered along the axial direction of the shafts. Several flexible heat-equalizing contact bodies arranged in a ring are fixedly connected to the outer sides of each of the heat-transfer rotating seats. A first motor is fixedly installed at one end of the inner side of the positioning heat-conducting seat. The output shaft of the first motor is fixedly connected to one of the rotating shafts. Pulleys are fixedly connected to one end of each of the two rotating shafts, and the two pulleys are connected by a belt drive.

[0012] In the above scheme, the first motor drives two rotating shafts to rotate synchronously in opposite directions through pulleys and belts, causing the heat transfer rotating seat and the flexible heat-equalizing contact body on it to revolve. The staggered distribution of the heat transfer rotating seat ensures that the massage trajectory covers all muscle groups on both sides of the spine, with no blind spots. The rotating flexible heat-equalizing contact body simulates the kneading and rolling massage techniques of human hands, applying cyclical rhythmic pressure to the waist muscles, promoting local blood circulation, and relieving muscle stiffness and soreness.

[0013] Preferably, the heat transfer rotor has a central heat storage cavity and several guide channels extending radially outward from the central heat storage cavity in a star shape; the axis of the guide channels does not pass through the geometric rotation center of the heat transfer rotor, but has a tangential deflection angle along the rotation direction of the axis; the flexible heat homogenizing contact body is a hollow flexible elastomer, and its root is sealed and fixed to the outer wall of the heat transfer rotor and communicates with the guide channels through a trapezoidal and hollow heat homogenizing buffer guide plate; the central heat storage cavity, the guide channels and the inner cavity of the flexible heat homogenizing contact body together form a sealed cavity, and the sealed cavity is filled with a liquid heat transfer medium; the liquid heat transfer medium is an insulating synthetic heat transfer oil with a flash point higher than 220℃ and a thermal conductivity greater than 0.42 W / (m·K); the flexible heat homogenizing contact body is made of thermally conductive silicone material with a graphene thermally conductive film pre-coated on the inner wall.

[0014] In the above scheme, when the heat transfer rotator rotates, the liquid heat transfer medium flows into the flexible heat homogenizing contact body under the action of centrifugal force, causing it to expand and harden. When pressed, it slowly flows back to form a hydraulic suspension buffer, eliminating the harsh touch of the traditional rigid flexible heat homogenizing contact body. The liquid heat transfer medium rolls and surges in the cavity, naturally producing a white noise like flowing water, which is transmitted to the user's ears through the structure, masking ambient noise and aiding relaxation and sleep. At the same time, the periodic shift of the center of gravity of the liquid heat transfer medium generates high-frequency secondary micro-vibrations, which are superimposed on the kneading action, making the massage force present a biomimetic rhythm and enhancing the massage penetration.

[0015] Preferably, the heat transfer rotating seat includes a main body fixedly sleeved on a rotating shaft, and a rotating ring rotatably sleeved around the main body. A bearing is provided between the rotating ring and the main body to achieve low-friction relative rotation between the two. A plurality of temperature-controlled heat energy conversion plates are evenly distributed in a ring on the outer wall of the rotating ring, and a plurality of throttling holes are opened on the temperature-controlled heat energy conversion plates. A plurality of heat storage cores are placed in the central heat storage cavity, and the outer diameter of the heat storage cores is smaller than the diameter of the throttling holes.

[0016] In the above scheme, the differential rotation between the rotating ring and the main body causes the temperature-controlled heat energy conversion plate to generate violent disturbances to the liquid heat transfer medium. The medium passes through the throttling orifice at high speed to form jets and vortices, which enhances the water hammer impact effect and strengthens the massage penetration sensation. At the same time, it generates a high-frequency sharp sound, which mixes with the low-frequency flowing water sound to form a broadband composite white noise. The heat storage core collides randomly under the drive of the liquid flow, emitting a crisp ticking sound, simulating the sound effect of a natural stream, further enhancing the hypnotic effect. The follow-up design of the rotating ring can also reduce fluid resistance, reduce motor load, and achieve energy saving.

[0017] Preferably, the temperature-controlled heat energy conversion plate adopts a composite structure: the interior is a neodymium iron boron permanent magnet core, the exterior is covered with an epoxy resin anti-corrosion layer, and the epoxy resin layer is further covered with a wear-resistant layer; the magnetic poles of two adjacent temperature-controlled heat energy conversion plates are opposite in direction; the heat storage core includes a microcrystalline glass sealed spherical shell, the micro-deformation heating core is made of high-frequency phase change heating alloy material and is suspended and confined in the center of the spherical shell, and the remaining space inside the spherical shell is filled with insulating thermally conductive silicone grease with a thermal conductivity greater than 2.0 W / (m·K).

[0018] In the above scheme, the magnetostrictive core is driven by an alternating magnetic field to undergo high-frequency deformation and generate heat, thereby achieving temperature-controlled hot compresses. At the same time, the magnetic field alternately agitates the liquid heat transfer medium, enhancing microscopic turbulence and composite sound field, thereby improving the massage penetration and hypnotic effect.

[0019] Preferably, a one-way throttling valve is provided in the cavity of the heat homogenizing buffer guide plate, so that the resistance of the liquid heat transfer medium flowing back from the flexible heat homogenizing contact body to the central heat storage cavity is greater than the resistance of flowing from the central heat storage cavity to the flexible heat homogenizing contact body.

[0020] In the above solution, the fast-in, slow-out characteristic of the one-way throttle valve allows the flexible, heat-equalizing contact body to expand rapidly and fully before contacting the back, and to contract slowly when pressed, maintaining a continuous and stable pushing force throughout the entire pressing process, simulating the technique of a senior massage therapist who presses without releasing; at the same time, it can adaptively conform to the contour of the waist, avoiding the impact of hard contact, and improving comfort while ensuring the pressure, making it especially suitable for massaging the sensitive muscle groups on both sides of the spine.

[0021] The beneficial effects of this invention are as follows: 1. The positioning and heat-conducting seat of the present invention adopts a movable structure. The posture follower frame is provided with an arc-shaped guide groove. The movable shafts at both ends of the positioning and heat-conducting seat are linked with the third support rod and the multi-link mechanism. When the backrest is tilted back, the entire mechanism will drive the positioning and heat-conducting seat to move upward along the arc-shaped trajectory and arch appropriately, which fills the gap between the waist and the backrest after the change of human posture, so that the lumbar spine is always firmly supported. In this way, the problem of the lower back being unsupported and easily fatigued and sore after lying down in a traditional massage chair is effectively solved.

[0022] 2. This invention designs the heat transfer rotating seat and the hollow flexible heat-equalizing contact body into a connected, sealed cavity filled with a liquid heat transfer medium. It is also equipped with a guide channel with a tangential deflection angle and a one-way throttling valve. When the heat transfer rotating seat rotates, centrifugal force drives the medium to circulate, forming a flexible pulsating hydraulic massage with "fast in, slow out". This structure can continuously push deep muscles and adapt to the contours of the waist, reducing the uncomfortable feeling of hard contact. At the same time, the liquid heat transfer medium rolls in the cavity to generate a low-frequency flowing water sound. After passing through the turbulence of the differential rotating ring and the jet of the throttling orifice, a high-frequency sharp sound is superimposed. In addition, the crisp ticking sound emitted by the random collision of the heat storage core is added. The three sounds are mixed into a wide-frequency composite natural stream sound effect. No additional electronic equipment is needed throughout the process, which can effectively mask environmental noise and improve the sleep-aiding effect.

[0023] 3. This invention incorporates a neodymium iron boron permanent magnet core within a temperature-controlled heat energy conversion plate, with adjacent temperature-controlled heat energy conversion plates having opposite magnetic pole directions, creating an alternating magnetic field during rotation. The heat storage core includes a magnetostrictive core and a heat-conducting medium, which undergoes high-frequency deformation and self-heating under the action of the alternating magnetic field. The heat is transferred to the liquid heat transfer medium through the heat-conducting medium, achieving speed-dependent temperature-controlled heat therapy that is positively correlated with the rotation speed. The higher the rotation speed, the greater the heat generation, automatically adapting to the massage intensity. No additional electrically controlled heating elements are required, simplifying the structure and reducing energy consumption. Simultaneously, the alternating magnetic field agitates the liquid heat transfer medium, enhancing microscopic turbulence and further improving the massage penetration and composite sound field effect.

[0026] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0027] like Figures 1 to 10 As shown, this invention proposes a thermotherapy adaptive positioning device equipped with a multi-link synchronous drive structure, the technical solution of which is as follows: As a specific embodiment of the present invention, refer to Figure 1 and Figure 2A thermotherapy adaptive positioning device equipped with a multi-link synchronous drive structure includes a chassis 1 with a fixed frame 2 fixedly connected to the top, a support frame 3 rotatably connected to the inside of the fixed frame 2, a support base plate 4 fixedly connected to the top of the support frame 3, a posture follower frame 5 hinged to one end of the support base plate 4, and a leg support plate 7 hinged to the other end of the support base plate 4. A swing mechanism 8 is provided on the chassis 1 to drive the support frame 3 to reciprocate. Two hydraulic rods 6 are hinged between the support base plate 4 and the support frame 3, allowing the posture follower frame 5 to move inwards. The positioning heat-conducting seat 9 is connected, and a multi-link mechanism 10 is set at the bottom of the support base plate 4. The multi-link mechanism 10, in coordination with the rotation of the posture follower frame 5, synchronously drives the leg support plate 7 to rotate and the positioning heat-conducting seat 9 to move upward and arch along the arc trajectory. A thermal therapy heat transfer mechanism 11 is set inside the positioning heat-conducting seat 9. The thermal therapy heat transfer mechanism 11 utilizes the circulating flow of liquid heat transfer medium inside the heat transfer rotating seat 112 and the flexible heat-equalizing contact body 113 to simultaneously realize flexible isobaric constant temperature heat therapy and water flow white noise hypnosis.

[0028] In use, the hydraulic rod 6 extends and drives the frame 5 to rotate backward relative to the bearing base plate 4. The multi-link mechanism 10 simultaneously drives the leg support plate 7 to unfold upward, and at the same time pulls the positioning heat conduction seat 9 to move upward and arch along the preset arc trajectory, fitting and supporting the waist of the human body in real time, avoiding the heat conduction surface from being suspended. After the warm therapy heat transfer mechanism 11 is activated, the heat transfer rotating seat 112 drives the flexible heat homogenizing contact body 113 to rotate. The internal liquid heat transfer medium periodically flows into and out of the flexible heat homogenizing contact body 113 under the action of centrifugal force, forming a flexible hydraulic buffer and isobaric constant temperature coverage fit. At the same time, the surging of the medium generates continuous water flow white noise to help the user relax.

[0029] As a specific embodiment of the present invention, refer to Figures 2 to 4 The multi-link mechanism 10 includes a first support rod 101 hinged to the bottom of the support base plate 4. One end of the first support rod 101 is rotatably connected to a second support rod 102. Both ends of the second support rod 102 are fixedly connected to a linkage bracket 103. The ends of the two linkage brackets 103 away from the second support rod 102 are hinged to the attitude follower frame 5. The other end of the first support rod 101 is hinged to a second link 104. The end of the second link 104 away from the first support rod 101 is hinged to the leg support plate 7. The middle of the two linkage brackets 103 is rotatably connected to a third support rod 105. The ends of the two third support rods 105 away from the linkage brackets 103 are hinged to a positioning heat conduction seat 9. Both ends of the positioning heat conduction seat 9 are fixedly connected to a movable shaft 106. The inner wall of the attitude follower frame 5 is provided with an arc-shaped guide groove 107 that slides with the movable shaft 106.

[0030] When the user operates the hydraulic rod 6 to push the posture follower frame 5 to rotate backward relative to the support base plate 4, it will directly pull the two connecting rod supports 103 hinged to it. The movement of the connecting rod supports 103 drives the second support rod 102 and the first support rod 101 rotatably connected to it, causing the first support rod 101 to swing around its hinge point at the bottom of the support base plate 4. The swing of the first support rod 101 will transmit the motion to the leg support plate 7 through the second connecting rod 104 at the other end, thereby driving the leg support plate 7 to flip upward. At the same time, the connecting rod supports The third support rod 105, which is hinged in the middle of the 103, will generate a push-pull motion as the angle of the connecting rod bracket 103 changes. This motion acts on the positioning heat conduction seat 9, forcing the movable shaft 106 fixed at both ends of the positioning heat conduction seat 9 to slide along the pre-set arc-shaped guide groove 107 on the inner wall of the attitude follower frame 5. This arc-shaped sliding trajectory is designed such that when the attitude follower frame 5 tilts backward, the movable shaft 106 slides upward in the arc-shaped guide groove 107, and at the same time, the positioning heat conduction seat 9 as a whole generates an upward displacement and a change in its own curvature relative to the attitude follower frame 5.

[0031] The multi-link mechanism 10 can synchronously achieve adaptive adjustment of the treatment surfaces of the legs and waist by only one input action: the rotation of the drive posture follower frame 5. Users do not need to operate separately for leg and waist support, realizing "one-click linkage" and greatly simplifying the user operation process.

[0032] The positioning heat-conducting seat 9 is not fixed. Through the cooperation of the movable shaft 106 and the arc-shaped guide groove 107, it can automatically move upward and arch during the process of leaning back. This simulates the changes in lumbar curvature and contact point with the backrest when the human body changes from sitting to semi-reclining and fully reclining postures. It can fill the gap in the waist caused by the change of posture in real time, and provide continuous and close-fitting heat-conducting surface support, effectively avoiding the defect of serious heat loss when lying down in traditional equipment.

[0033] As a specific embodiment of the present invention, refer to Figure 6 The inner side of the positioning heat-conducting seat 9 is provided with a thermal therapy heat transfer mechanism 11. The thermal therapy heat transfer mechanism 11 includes two parallel rotating shafts 111 that are rotatably connected to the inner side of the positioning heat-conducting seat 9. Several heat transfer rotating seats 112 are fixedly connected to the two rotating shafts 111 and are equidistantly distributed along the axis of the rotating shafts 111. The heat transfer rotating seats 112 on the two rotating shafts 111 are staggered in the axial direction of the rotating shafts 111. Several flexible heat-equalizing contact bodies 113 arranged in a ring are fixedly connected to the outer side of the heat transfer rotating seats 112. A first motor 114 is fixedly installed at one end of the inner side of the positioning heat-conducting seat 9. The output shaft of the first motor 114 is fixedly connected to one of the rotating shafts 111. A pulley 115 is fixedly connected to one end of the two rotating shafts 111. The two pulleys 115 are connected by belt drive.

[0034] The first motor 114 drives a rotating shaft 111 fixedly connected to its output shaft to rotate. The rotating shaft 111 transmits power to the pulley 115 of another rotating shaft 111 through a pulley 115 and a belt at one end, thereby achieving synchronous and opposite rotation of the two rotating shafts 111. Each rotating shaft 111 has multiple sets of heat transfer rotating seats 112 that are equidistantly distributed along the axial direction, and the heat transfer rotating seats 112 on the two rotating shafts 111 are staggered in the axial direction. Each heat transfer rotating seat 112 is also equipped with a ring of flexible heat-equalizing contact body 113 on its outer periphery. When the rotating shaft 111 rotates, it drives the heat transfer rotating seat 112 and the flexible heat-equalizing contact body 113 on it to revolve. The staggered layout ensures that the constant temperature heat treatment area can cover all soft tissue groups on both sides of the spine, avoiding blind spots in the temperature control of physiotherapy.

[0035] The device uses a rotating heat transfer seat 112 with a flexible heat-spreading contact body 113 to simulate the physiotherapy technique of kneading and rolling the muscles of the waist with the thumb or knuckles of a human hand. The staggered layout ensures that the force can be applied to the muscle groups on both sides of the spine. The continuously rotating flexible heat-spreading contact body 113 can apply cyclical and rhythmic pressure to the waist muscles, which helps to promote local blood circulation, relieve the stiffness and soreness of the waist muscles caused by prolonged sitting or fatigue, and achieve deep relaxation of the waist muscles.

[0036] As a specific embodiment of the present invention, refer to Figures 7 to 9 The heat transfer rotor 112 has a central heat storage cavity and several guide channels that extend radially outward from the central heat storage cavity in a star shape. The axis of the guide channels does not pass through the geometric rotation center of the heat transfer rotor 112, but has a tangential deflection angle of 5°-15° along the rotation direction of the rotating shaft 111. This allows for a stronger directional impact of liquid flow by utilizing centrifugal force during rotation. Meanwhile, the flexible heat homogenizing contact body 113 is a hollow flexible elastomer made of thermally conductive silicone material with a graphene thermally conductive film pre-coated on the inner wall. Its root is sealed and fixed to the outer wall of the heat transfer rotor 112 by a trapezoidal and hollow heat homogenizing buffer guide plate 1131. The central heat storage cavity, the guide channels, and the inner cavity of the flexible heat homogenizing contact body 113 together form a completely sealed heating cavity.

[0037] The sealed cavity is filled with a liquid heat transfer medium, which is an insulating synthetic heat transfer oil with a flash point higher than 220℃ and a thermal conductivity greater than 0.42 W / (m·K). The volume of the liquid heat transfer medium is controlled to be 60%-80% of the total volume of the sealed cavity. When the rotating shaft 111 drives the heat transfer rotating seat 112 to rotate, the liquid heat transfer medium will flow into the flexible heat homogenizing contact body 113 under the action of centrifugal force, causing it to expand and harden. When it comes into contact with the waist of the human body and is subjected to pressure, some of the medium is squeezed back into the central heat storage cavity, forming a kind of "hydraulic suspension" adaptive buffering effect, avoiding hard collisions. Meanwhile, due to the presence of gas spaces not filled with liquid heat transfer medium, the liquid heat transfer medium churns and breaks up violently within the central heat storage chamber and flow channel. On one hand, this produces a continuous and gentle "flowing water" white noise effect, which is transmitted to the user's eardrum through the soft pad, effectively inducing the user to relax and fall asleep. On the other hand, the periodic shift of the center of gravity and redistribution of mass of the liquid heat transfer medium provides the rotating heat transfer seat 112 with dynamically changing rotational inertia, generating high-frequency secondary micro-vibrations. These vibrations, superimposed on the original rotating kneading motion, make the force of the flexible heat-equalizing contact body 113 acting on the human body present a biomimetic rhythmic feeling of "light, heavy, fast, slow," greatly improving the comfort and penetration of the massage.

[0038] As a specific embodiment of the present invention, refer to Figures 8 to 9 The heat transfer rotating base 112 includes a main body fixedly sleeved on the rotating shaft 111, and a rotating ring 1121 rotatably sleeved around the main body. A miniature bearing is provided between the rotating ring 1121 and the main body to achieve low-friction and high-reliability relative rotation between the two. Several temperature-controlled heat energy conversion plates 1122 are evenly distributed in a ring along the circumference on the outer wall of the rotating ring 1121. These temperature-controlled heat energy conversion plates 1122 extend radially into the central heat storage cavity of the heat transfer rotating base 112. To increase the turbulence effect of the liquid flow, several throttling holes are opened on each temperature-controlled heat energy conversion plate 1122. Several heat storage cores 1123 are placed in the central heat storage cavity. The outer diameter of the heat storage cores 1123 is smaller than the diameter of the throttling holes.

[0039] When the rotating shaft 111 drives the main body of the heat transfer rotating seat 112 to rotate at high speed, due to the isolation effect of the bearing, the rotating ring 1121 and the temperature control heat energy conversion plate 1122 on it will not immediately reach the same angular velocity as the main body. Instead, a relatively lagging, differential oscillation or rotation will occur. This relative rotational motion between the main body and the rotating ring 1121, together with the cutting of the liquid by the temperature control heat energy conversion plate 1122 itself, will cause violent disturbance to the liquid heat transfer medium in the central heat storage chamber. The liquid heat transfer medium is forced to be ejected at high speed from the throttling orifice, forming countless tiny jets and vortices, which greatly enhances the "water hammer impact" effect of the liquid flow and makes the massage penetration more powerful.

[0040] On the one hand, when the liquid heat transfer medium passes through the throttling orifice on the temperature-controlled heat energy conversion plate 1122 at high speed, it produces a high-frequency sharp sound similar to a whistle or wind chime. This sound mixes with the low-frequency "gurgling" sound generated by the fluid surging, forming a wide-range, highly natural, and immersive composite white noise. On the other hand, the heat storage core 1123, which is smaller than the throttling orifice, can freely shuttle within the cavity under the influence of the liquid flow. It continuously collides randomly with the inner wall of the temperature-controlled heat energy conversion plate 1122, the edge of the throttling orifice, and other heat storage cores 1123. This collision produces a crisp and pleasant "tickling" sound, simulating the natural sound effects of "rain hitting banana leaves" or "stream striking rocks." These sounds of different frequencies and timbres intertwine, enhancing the layering and realism of auditory hypnosis, and more effectively guiding users into a state of deep relaxation.

[0041] In addition, the rotation of the rotating ring 1121 causes the temperature control heat energy conversion plate 1122 to "follow the flow," recovering some of the liquid kinetic energy and converting it into the rotational kinetic energy of the rotating ring 1121, indirectly assisting the main body to maintain rotation, effectively reducing the load on the first motor 114, and achieving a certain energy-saving effect.

[0042] As a specific embodiment of the present invention, refer to Figures 8 to 10 The temperature control heat energy conversion plate 1122 has a neodymium iron boron permanent magnet core inside. The outside of the permanent magnet core is covered with an epoxy resin anti-corrosion layer to prevent the liquid heat transfer medium from corroding the neodymium iron boron material. The epoxy resin layer is then covered with a wear-resistant layer to resist the wear caused by long-term collision between the liquid heat transfer medium and the heat storage core 1123, ensuring the service life of the temperature control heat energy conversion plate 1122.

[0043] In particular, the magnetic poles of two adjacent temperature-controlled heat energy conversion plates 1122 are in opposite directions. This alternating magnetic pole arrangement creates a non-uniform magnetic field region with densely alternating magnetic field lines and rapidly changing directions in the central heat storage cavity outside the rotating ring 1121.

[0044] The thermal storage core 1123 includes a microcrystalline glass sealed spherical shell, and a micro-deformation heating core is made of a high-frequency phase change heating alloy material and suspended and confined in the center of the spherical shell. The remaining space inside the spherical shell is filled with insulating thermally conductive silicone grease with a thermal conductivity greater than 2.0 W / (m·K).

[0045] When the rotating shaft 111 drives the main body to rotate, the rotating ring 1121 rotates at a different speed through the bearing. At this time, the temperature-controlled heat energy conversion plate 1122 fixed on the rotating ring 1121 carries the alternating magnetic field and makes circular motion in the central heat storage cavity. Since the magnetic poles of the adjacent temperature-controlled heat energy conversion plates 1122 are opposite, the liquid heat transfer medium in the cavity will be subjected to a periodic magnetic stirring with alternating directions. This non-contact "magnetic stirring" effect adds a deeper and more microscopic fluid turbulence effect on the basis of the original mechanical disturbance, making the mixing of liquid and gas more complete, and the spectrum of water flow white noise is richer and closer to the real water sound in nature.

[0046] As the thermal storage core 1123 moves freely through the central heat storage cavity under the influence of the liquid flow, it repeatedly enters the strong magnetic field region formed by adjacent temperature-controlled thermal energy conversion plates 1122. Due to the staggered arrangement of the magnetic poles of the adjacent temperature-controlled thermal energy conversion plates 1122, the direction and intensity of the magnetic field experienced by the thermal storage core 1123 rapidly reverse after passing through each pair of temperature-controlled thermal energy conversion plates 1122. Under the action of the high-frequency alternating magnetic field, the magnetostrictive core inside the thermal storage core 1123 will produce rapid and minute "elongation-shortening" cyclic deformation. This high-frequency mechanical deformation generates internal friction within the material, thereby efficiently... Heat is generated (i.e., magnetostrictive heating effect), and the generated heat is rapidly conducted to the outer shell of the heat storage core 1123 through the heat conduction medium, thereby heating the surrounding liquid heat transfer medium. Compared with the aforementioned collision friction heating or chemical exothermic heating, this "magnetostrictive heating" has the advantages of high thermal efficiency and the heat generation being proportional to the rotation speed (i.e., the frequency of magnetic field change). When the massage chair is running at high speed for deep massage, the heat generation automatically increases, providing more sufficient heat to the user's waist. When running at low speed for relaxation, the heat generation decreases to avoid overheating. This adaptive speed-dependent temperature control characteristic is a prominent feature of this embodiment.

[0047] In addition to the sounds of flowing water and collisions, the deformation process of the magnetostrictive core under a high-frequency alternating magnetic field generates weak but highly regular high-frequency vibrational sound waves. These sound waves, superimposed on the original white noise of the flowing water, form a background sound similar to "buzzing" or "natural resonance," further enhancing the hypnotic effect. At the same time, the force movement of the heat storage core 1123 in the magnetic field and its own high-frequency micro-vibrations are transferred to the flexible heat-equalizing contact body 113 through the liquid heat transfer medium, allowing the user's waist to feel a micro-high-frequency vibration sensation in addition to kneading and impact. This has unique therapeutic value for relieving deep fatigue of local muscles and can further enhance the hypnotic effect of ASMR.

[0048] Furthermore, because the heat-conducting medium fills the gap between the core and the outer shell, the outer wall of the core does not directly collide with the inner wall of the outer shell when the core undergoes high-frequency magnetostrictive deformation. The "hard point contact" or "fretting wear" that is unavoidable in traditional structures is eliminated. Instead, the core evenly transfers deformation energy and heat to the outer shell through the heat-conducting medium, reducing the wear on the core surface and the propagation of microcracks on the inner wall of the outer shell caused by long-term high-frequency vibration. The working life of the heat storage core 1123 is extended, which can meet the service life requirements of massage chair products and significantly enhance the reliability and durability of the product.

[0049] As can be seen, this embodiment, through the organic combination of the rotating ring 1121, the temperature-controlled heat energy conversion plate 1122 and the heat storage core 1123, not only achieves mechanical kneading, hydraulic self-adaptation and white noise sleep aid, but also further possesses advanced composite functions such as multi-band composite sound field and self-heating passive heat therapy. The realization of these functions depends on mechanical movement and material properties, without the need for additional voice modules and heating wires, simplifying the structure and reducing energy consumption, improving service life and user experience, and enhancing product reliability and market competitiveness.

[0050] As a specific embodiment of the present invention, a one-way throttling valve is provided in the cavity of the heat equalization buffer guide plate 1131, so that the resistance of the liquid heat transfer medium flowing back from the flexible heat equalization contact body 113 to the central heat storage cavity is greater than the resistance of flowing from the central heat storage cavity to the flexible heat equalization contact body 113.

[0051] When the rotating shaft 111 drives the heat transfer rotating seat 112 to rotate, the liquid heat transfer medium in the central heat storage chamber is thrown outward by centrifugal force. The liquid heat transfer medium passes smoothly through the one-way throttle valve with low resistance and quickly flows into the inner cavity of the hollow flexible heat homogenizing contact body 113. This allows the flexible heat homogenizing contact body 113 to expand rapidly before contacting the back, making full preparation for the subsequent pressing.

[0052] When the full, flexible heat-equalizing contact body 113 rotates with the heat transfer rotating seat 112 to face the waist of the human body and is squeezed by the reaction force of the human body, the pressure of the liquid heat transfer medium in the inner cavity of the flexible heat-equalizing contact body 113 increases, and there is a tendency to flow back to the central heat storage chamber. At this time, the one-way throttle valve is in a high resistance state, and the flexible heat-equalizing contact body 113 will not be flattened instantly like an ordinary balloon, but will gradually shrink at a slow and controlled speed. This "slow release" characteristic produces two important therapeutic effects: First, continuous pushing force: throughout the entire pressing process, the internal liquid pressure of the flexible heat-equalizing contact body 113 is always maintained at a high level, forming a continuous, stable and uninterrupted pushing force on the waist muscles. This continuous force of "pressing without releasing" can effectively penetrate into the deep fascia and muscle tissue, simulating the professional technique of a senior massage therapist when performing acupressure, and improving the constant temperature penetration effect of deep heat therapy. Second, flexible adaptive fit: Since the flexible heat-equalizing contact body 113 contracts slowly, it can adapt its deformation in a flexible manner according to the contour of the human waist, avoiding the "hard-on-hard" impact of the traditional rigid flexible heat-equalizing contact body 113, and improving comfort while ensuring sufficient pressing pressure.

[0053] As the current flexible heat exchanger 113 rotates away from the human body along with the heat transfer turntable 112, the resetting process is completed by two forces working together: On the one hand, the next flexible heat exchanger 113 enters the maximum centrifugal force zone, and a large amount of liquid heat transfer medium is quickly thrown into the flexible heat exchanger 113, causing the instantaneous pressure of the central heat storage chamber to drop, forming a negative pressure zone relative to the inner cavity of the current flexible heat exchanger 113, generating suction force; on the other hand, the flexible heat exchanger 113 is subjected to back compression force and elastic stretching during the filling of liquid heat transfer medium, accumulating a certain amount of energy. After the external force gradually weakens, the elastic contraction force of the flexible heat exchanger 113 continues to squeeze the remaining liquid heat transfer medium into the central heat storage chamber, and the liquid heat transfer medium in the flexible heat exchanger 113 is efficiently sent back to the central heat storage chamber for the charging of the next flexible heat exchanger 113.

[0054] As a specific embodiment of the present invention, refer to Figure 2 The top of the attitude follower frame 5 is provided with a head attitude support frame 12, and the inner side of the attitude follower frame 5 is provided with an adjustment mechanism 13 for driving the vertical movement of the head attitude support frame 12.

[0055] The head posture support frame 12 is slidably connected to the top of the posture follower frame 5. When the user needs to adjust the height of the head posture support frame 12, the head posture support frame 12 can be directly pulled by the adjustment mechanism 13 to adjust the height. The adjustment mechanism 13 can be a ratchet mechanism with a self-locking function.

[0056] As a specific embodiment of the present invention, refer to Figure 2 and Figure 5 The head posture support frame 12 is provided with a light-blocking and calming component 14 at its top. The light-blocking and calming component 14 includes damping shafts 141 that are fixedly connected to both ends of the head posture support frame 12. One end of each damping shaft 141 is fixedly connected to a mounting base 142. Insert rods 143 that pass through the mounting base 142 are inserted into the inner side of each mounting base 142. Eye shields 144 are rotatably connected to the top ends of the two insert rods 143. Telescopic members 145 for driving the insert rods 143 to slide are provided on the inner side of each mounting base 142.

[0057] When the goggles 144 are needed, the telescopic component 145 initiates the linear sliding of the drive rod 143. The linear sliding of the drive rod 143 is directly converted into the forward and backward translational movement of the goggles 144 relative to the head posture support frame 12 and the user's face, thereby extending or retracting the goggles 144. When the user applies manual torque to the goggles 144, it can overcome the resistance of the damping shaft 141, causing the goggles 144 to rotate around the axis of the damping shaft 141. Once the user stops applying torque, the resistance provided by the damping shaft 141 is sufficient to keep the goggles 144 at the currently adjusted pitch angle without swaying freely.

[0058] The present invention integrates an adjustable light-blocking and calming component 14 into the top of the head posture support frame 12 of the massage chair. The telescopic component 145 enables automatic forward and backward translation, and the damping axis enables arbitrary tilt angle locking. Users do not need to wear an additional independent eye mask. It can be pushed to the face for precise light blocking with one click. At the same time, it works with the micro vibration motor inside the eye mask to achieve soothing massage around the eyes.

[0059] In summary, this invention uses the light-blocking and calming component 14 to block light and massage the area around the eyes, the heat transfer mechanism 11 to generate the sound of flowing water and the sensation of warmth, and the swing mechanism 8 to perform low-frequency back-and-forth swaying. It helps users relax and fall asleep through multiple aspects such as vision, hearing, touch and body swaying. The whole process does not require the use of electronic sound modules or complex control systems. It has a simple structure, low cost and reliable operation.

[0060] Working principle: When the user adjusts from a sitting to a lying position, the hydraulic rod 6 is activated to drive the posture follower frame 5 to rotate backward. The multi-link mechanism 10 links the leg support plate 7 and the positioning heat-conducting seat 9 to achieve adaptive heat-conducting surface contact support. After the posture adjustment is completed, the swing mechanism 8 can be activated to drive the entire component to swing back and forth. After the heat transfer mechanism 11 is activated, the first motor 114 drives the rotating shaft 111 to rotate. Through the pulley 115 and belt, the other rotating shaft 111 rotates synchronously in opposite directions. The heat transfer rotating seat 112 and the flexible heat-equalizing contact body 113 rotate to achieve waist support. The liquid heat transfer medium in the heat transfer rotating seat 112 is kneaded and rolled, and under the action of centrifugal force, it flows into the flexible heat homogenizing contact body 113 through the guide channel. The differential rotation of the rotating ring 1121 and the main body drives the temperature control heat energy conversion plate 1122 to disturb the liquid and generate multi-frequency white noise. The heat storage core 1123 is magnetostrictive and self-heating under the action of alternating magnetic field to achieve speed-controlled heat therapy. The one-way throttling valve in the heat homogenizing buffer guide plate 1131 makes the medium enter quickly and exit slowly to form a continuous pushing force, completing hydraulic pulse massage, composite sound field sleep aid and adaptive heat therapy. The height of the head posture support frame 12 can be adjusted by adjusting mechanism 13. When eye care is needed, the telescopic component 145 is activated to drive the plug rod 143 to extend from the mounting base 142, pushing the eye mask 144 to the face. The tilt angle of the eye mask 144 around the damping axis 141 can be manually adjusted, and the micro vibration motor inside the eye mask 144 can be activated to achieve eye vibration massage and light blocking.

[0061] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
