Description

Technical Field

[0001] The present invention relates to the technical field of magnetic therapy, and more specifically, to a gear-driven portable folding magnetic therapy device. Background Art

[0002] A gear-driven portable folding magnetic therapy device is a healthcare device that combines mechanical transmission technology, portable design concepts, and magnetic therapy functions. From a mechanical structure perspective, it uses a gear transmission system. Through the meshing and rotation of gears, power is transmitted and converted to drive the various moving parts of the device to achieve specific functional operations, such as controlling the angle adjustment and position movement of the magnetic therapy area. Compared with other transmission methods, gear transmission has advantages such as accurate transmission ratio, high transmission efficiency, and compact structure, which can ensure the stability and accuracy of the device during operation.

[0003] Under normal circumstances, when using a traditional magnetic therapy cushion, the magnetic therapy pad is fixed at a specific angle and it is difficult to fit the back curve of the user. When the user relies on the magnetic therapy board, they can only receive static massage with the massage beads on the treatment board, resulting in the user's back acupoints being difficult to receive precise and effective massage. Moreover, the magnetic therapy board generates a large amount of heat during long-term operation, which is extremely easy to cause skin burns to the user. The traditional heat dissipation method is to open ventilation holes on both sides of the device, but this method has extremely low heat dissipation efficiency, and the ventilation holes are extremely easy to be blocked by dust. Once blocked, effective heat dissipation cannot be achieved, seriously affecting the use experience and safety of the magnetic therapy cushion. In view of this, we propose a gear-driven portable folding magnetic therapy device. Summary of the Invention

[0004] The purpose of the present invention is to provide a gear-driven portable folding magnetic therapy device to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides a gear-driven portable folding magnetic therapy device, including a base. A backrest pad is rotatably connected to the top of the base. A massage mechanism and a magnetic therapy board are arranged inside the backrest pad. By adjusting the angle of the backrest pad, the massage mechanism can fit the back curve of the human body. Through the design of a circumferential massage structure, the massage mechanism can achieve large-area coverage of the user's back and massage multiple acupoints simultaneously. A ventilation mechanism is arranged on one side of the massage mechanism. When the massage mechanism rotates and massages, it synchronously drives the ventilation mechanism to reciprocate. Moreover, the airflow generated when the ventilation mechanism moves promotes the air flow inside the backrest pad to form a heat exchange, ensuring the stable operation of the magnetic therapy board.

[0006] The beneficial effects of the present invention are: 1. In the present invention, when the first rotating rod of the massage mechanism rotates, it drives the second gear to operate through the first gear. The rotation of the second gear drives the power rod, thereby causing the pushing air plate to reciprocate on the guiding slide rod. The driving force generated during the massage process is ingeniously converted into the power source of the ventilation mechanism, accelerating the air flow inside the backrest pad. This design can not only quickly remove the heat generated by the operation of the magnetic therapy plate, achieve heat and cold exchange, ensure the stable operation of the magnetic therapy plate, and extend its service life, but also bring a more comfortable usage experience to the user, avoiding the stuffy feeling caused by heat accumulation. Meanwhile, the first rotating rod and the second rotating rod in the massage mechanism are connected by a synchronous belt. When the first rotating rod rotates, it drives the synchronous belt and the second rotating rod to operate. During the rotation, the equally spaced convex blocks on the surface of the synchronous belt can accurately locate and massage the back acupoints of the user according to the angle of the backrest pad fitting the human back curve.

[0007] 2. In the present invention, the backrest pad can adjust the angle according to the needs of the user, enabling the backrest pad to closely fit the user's back. As a result, the synchronous belt and the surface convex blocks in the massage mechanism can accurately locate and massage the back acupoints according to the unique contour of the human back during rotation, effectively relieving the tension and fatigue of the back muscles and promoting blood circulation in the body. After the blood circulation accelerates, the metabolism of human tissues also improves, which helps the magnetic field generated by magnetic therapy to better penetrate into the human body. Magnetic therapy uses the magnetic field to stimulate and regulate the human meridians, acupoints, and diseased parts. The rapid blood flow can transmit the biological effects excited by the magnetic field faster and more widely to all parts of the body, thereby enhancing the effect of magnetic therapy and more effectively improving the physiological functions of the human body, achieving better health care and treatment purposes. Moreover, the backrest pad can be rotated onto the seat cushion and made parallel to the seat cushion, enabling the backrest pad to be folded and stored for convenient carrying.

[0008] As a further improvement of this technical solution, a rotating shaft is rotatably connected inside the base. One end of the rotating shaft is threadedly connected with a fixing cap. The backrest pad is fixed at a position suitable for the human back curve through the cooperation of the rotating shaft and the fixing cap. One side of the base is fixedly connected with a bottom plate, and a seat cushion is fixedly connected inside the bottom plate.

[0009] The beneficial effect of adopting the above further solution is that the rotating shaft rotatably connected inside the base, in cooperation with the fixing cap threadedly connected at one end, enables the angle of the backrest pad to be flexibly adjusted. The user can rotate the backrest pad to a suitable angle according to their own back curve and then fix it by tightening the fixing cap, greatly improving the personalization degree of the device and ensuring that the massage mechanism and the magnetic therapy plate can closely fit the backs of different users.

[0010] As a further improvement of this technical solution, a ventilation plate is clamped on one side of the backrest pad close to the magnetic therapy plate. The ventilation plate is made of sound-insulating material and is used to shield the interference of the massage mechanism on the magnetic therapy plate. Sliding grooves are provided inside both ends of the backrest pad for the reciprocating movement of the ventilation mechanism. A guiding slide bar is fixedly connected inside the sliding groove on the backrest pad to guide the movement of the ventilation mechanism. A memory foam pad is fixedly connected to one side of the outer part of the backrest pad.

[0011] The beneficial effect of adopting the above further solution is that the presence of the ventilation plate effectively blocks the interference factors generated by the massage mechanism, ensuring that the magnetic therapy plate can work in a relatively quiet and stable environment, maintaining the accuracy and effectiveness of magnetic therapy, and enabling users to fully enjoy the health care effects brought by magnetic therapy.

[0012] As a further improvement of this technical solution, the massage mechanism includes a first rotating rod rotatably connected inside the backrest pad. A synchronous belt is sleeved on the surface of the first rotating rod. A second rotating rod is sleeved inside the synchronous belt, and the second rotating rod is rotatably connected to the backrest pad. Convex blocks are equidistantly fixed on the surface of the synchronous belt for massaging the user's back during rotation. Fixed sleeves are rotatably connected to both ends of the first rotating rod and the second rotating rod, and one side of the fixed sleeve is fixedly connected to the inner wall of the backrest pad to stabilize the first rotating rod and the second rotating rod. First gears are fixedly connected to the outer circles of both ends of the first rotating rod. A drive motor is fixedly installed at one end of the backrest pad close to the first rotating rod, and the output end of the drive motor is fixedly connected to the inner wall of the first gear.

[0013] The beneficial effect of adopting the above further solution is that the convex blocks equidistantly arranged on the surface of the synchronous belt rotate driven by the first rotating rod and the second rotating rod, and can accurately massage the user's back. Since the backrest pad can be adjusted in angle to fit the curve of the human back, the convex blocks can accurately stimulate each acupoint on the back according to the unique contour of the back during rotation. Acupoint massage helps to promote the circulation of qi and blood in the body's meridians, relieve discomfort symptoms such as back muscle tension and pain caused by meridian blockage and poor qi and blood circulation, and achieve effective conditioning and relaxation of the body.

[0014] As a further improvement of this technical solution, the ventilation mechanism includes a pushing air plate slidably connected to the guiding slide bar. Power rods are rotatably connected to both sides of the bottom of the pushing air plate. One end of the power rod is rotatably connected to a second gear, and one end of the power rod is rotatably connected to the second gear near the outer edge. A bracket is rotatably connected to the back of the second gear. The bottom surface of the bracket is fixedly connected to the backrest pad. The second gear is meshed with the bottom of the first gear. Slide bars are slidably connected to both sides of the top of the pushing air plate to ensure the stability of the pushing air plate during movement.

[0015] The beneficial effects of adopting the above further scheme are as follows: the ventilation mechanism ingeniously converts the driving force generated by the massage mechanism into the power for its own operation. The first gear rotates when the massage mechanism operates, driving the second gear, and then driving the ventilation mechanism to work. Without an additional power source, it not only simplifies the device structure but also improves the energy utilization efficiency, realizing the organic linkage of the massage and ventilation functions and giving full play to the functional advantages of the entire device.

[0016] In addition to the purposes, features, and advantages described above, the present invention has other purposes, features, and advantages. The following will refer to the drawings to further describe the present invention in detail. Brief Description of the Drawings

Detailed Embodiments

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] The present invention provides the following preferred embodiments See also Figure 1 - Figure 7 As shown, this embodiment provides a gear-driven portable foldable magnetic therapy device, comprising a base 100, the top of which is rotatably connected to a backrest plate 200, the interior of which is provided with a massage mechanism 300 and a magnetic therapy plate 201. By adjusting the angle of the backrest plate 200, the massage mechanism 300 can fit the curve of the human back. The massage mechanism 300, through the design of a surround-type massage structure, can achieve large-area coverage of the user's back and simultaneously massage multiple acupuncture points. A ventilation mechanism 400 is provided on one side of the massage mechanism 300. When the massage mechanism 300 rotates and massages, it synchronously drives the ventilation mechanism 400 to move back and forth. In addition, the airflow generated by the ventilation mechanism 400 during movement promotes the flow of air inside the cushion plate 200 to form a heat exchange, ensuring the stable operation of the magnetic therapy plate 201.

[0021] The massage mechanism 300 is driven by the driving motor to rotate, so as to achieve the effect of continuous massage on the user's back. When the driving motor rotates, it will synchronously drive the push plate 401 in the ventilation mechanism 400 to reciprocate. Figure 2 , as follows: The driving motor drives the first gear 305 to rotate, thereby driving the second gear 403 to rotate. When the second gear 403 rotates, it drives the power rod 402 to pull the push air plate 401 to perform reciprocating motion. The push air plate 401 generates airflow during the reciprocating motion (because heat dissipation holes are provided on both sides of the backrest plate 200. When the push air plate 401 moves from point a to point b, it drives the external cold air to blow from point a to point b. When the push air plate 401 moves from point b to point a, the hot air at point b moves to point a and flows out of the backrest plate 200, forming a cold and heat exchange). This process accelerates the flow of air inside the backrest plate 200, can quickly take away the heat generated by the magnetic therapy plate 201, and realize cold and heat exchange. On the basis of the above, the specific structure is disclosed in detail: The base 100 is internally rotatably connected to a rotating shaft 101, one end of which is threadedly connected to a fixing cap. The rotation shaft 101 and the fixing cap cooperate to fix the backrest plate 200 in a position that fits the curve of the human back. One side of the base 100 is fixedly connected to a bottom plate, and the inside of the bottom plate is fixedly connected to a seat cushion 102. Using the principle of mechanical connection, the rotating shaft 101 inside the base 100 is rotatably connected to the backrest pad 200, enabling the backrest pad 200 to adjust the angle around the rotating shaft 101. One end of the rotating shaft 101 is threadedly connected with a fixing cap. After adjusting the angle of the backrest pad 200, by tightening the fixing cap and utilizing the fastening effect of the thread, the backrest pad 200 is stably fixed at the corresponding position. This design conforms to the ergonomic principle. Since the back curves of different users vary, by flexibly adjusting the angle of the backrest pad 200, it can closely fit the back curve of the human body. When the backrest pad 200 fits the back curve, the massage mechanism 300 inside the backrest pad 200 can more accurately massage the back acupoints of the user, and the magnetic therapy plate 201 can also better act on the human back, enhancing the massage and magnetic therapy effects, effectively relieving back discomfort, and improving the health care effect.

[0022] On one side of the backrest pad 200 close to the magnetic therapy plate 201, a ventilation plate 202 is snap-connected. The ventilation plate 202 is made of sound-insulating material and is used to shield the interference of the massage mechanism 300 on the magnetic therapy plate 201. Sliding grooves are respectively opened inside both ends of the backrest pad 200 for the reciprocating movement of the ventilation mechanism 400. A guiding slide rod 203 is fixedly connected inside the sliding groove on the backrest pad 200 for guiding the movement of the ventilation mechanism 400. A memory foam pad 204 is fixedly connected to one side of the outside of the backrest pad 200; The ventilation plate 202 snap-connected on one side of the backrest pad 200 close to the magnetic therapy plate 201 is made of sound-insulating material. Its core function is to shield the interference of the massage mechanism 300 on the magnetic therapy plate 201. When the massage mechanism 300 is operating, due to motor drive, component rotation, etc., certain noise and mechanical vibration will be generated. These noise and vibration may affect the stable operation of the magnetic therapy plate 201, interfere with the magnetic field generated by it, and thus reduce the magnetic therapy effect. The existence of the ventilation plate 202 effectively blocks the interference factors generated by the massage mechanism 300, ensuring that the magnetic therapy plate 201 can work in a relatively quiet and stable environment, maintaining the accuracy and effectiveness of magnetic therapy, and enabling users to fully enjoy the health care effects brought by magnetic therapy.

[0023] The massage mechanism 300 includes a first rotating rod 301 rotatably connected inside the backrest plate 200. A synchronous belt 302 is sleeved on the surface of the first rotating rod 301. A second rotating rod 303 is sleeved inside the synchronous belt 302, and the second rotating rod 303 is rotatably connected to the backrest plate 200. The surface of the synchronous belt 302 is equidistantly fixed with bumps 304 for massaging the user's back during rotation. Both ends of the first rotating rod 301 and the second rotating rod 303 are rotatably connected with fixed sleeves, and one side of the fixed sleeve is fixedly connected to the inner wall of the backrest plate 200 to stabilize the first rotating rod 301 and the second rotating rod 303. Outer rings at both ends of the first rotating rod 301 are fixedly connected with first gears 305. A driving motor is fixedly installed at one end of the backrest plate 200 close to the first rotating rod 301, and the output end of the driving motor is fixedly connected to the inner wall of the first gear 305; The driving motor fixedly installed inside the backrest plate 200 is the power source for the operation of the entire massage mechanism 300. The output end of the driving motor is connected to the inner wall of the first gear 305 fixedly connected to the outer rings at both ends of the first rotating rod 301. When the driving motor starts, it outputs torque to drive the first gear 305 to rotate, and then the first rotating rod 301 connected thereto starts to rotate. This power transmission process is stable and efficient, ensuring that the massage mechanism 300 can operate continuously and provide uninterrupted massage services for the user. The synchronous belt 302 sleeved on the surface of the first rotating rod 301 and the second rotating rod 303 sleeved inside the synchronous belt 302 together constitute a synchronous transmission system. When the first rotating rod 301 rotates, the second rotating rod 303 is driven to rotate synchronously through the friction of the synchronous belt 302. This synchronous rotation ensures that the bumps 304 equidistantly fixed on the surface of the synchronous belt 302 can massage the user's back at a consistent speed and rhythm during rotation. Whether it is the area driven by the first rotating rod 301 or the second rotating rod 303, the bumps 304 can work in coordination to avoid discomfort caused by inconsistent massage rhythms and provide the user with a uniform and comfortable massage experience.

[0024] The ventilation mechanism 400 includes a push air plate 401 slidably connected to the guide slide bar 203. Both sides of the bottom of the push air plate 401 are rotatably connected with power rods 402. One end of the power rod 402 is rotatably connected with a second gear 403, and one end of the power rod 402 is rotatably connected to the second gear 403 near the outer edge. The back of the second gear 403 is rotatably connected with a bracket, and the bottom surface of the bracket is fixedly connected to the backrest plate 200. The second gear 403 is meshed with the bottom of the first gear 305. Both sides of the top of the push air plate 401 are slidably connected with slide bars to ensure the stability of the push air plate 401 during movement; The pushing air plate 401 is slidably connected to the guiding slide rod 203 and can reciprocate inside the backrest cushion 200 under the push of the power rod 402. When the massage mechanism 300 works, the first gear 305 rotates to drive the meshing second gear 403 to rotate. The rotation of the second gear 403 drives the power rod 402 to move, thereby pushing the pushing air plate 401 to slide back and forth on the guiding slide rod 203. This process accelerates the air flow inside the backrest cushion 200, can quickly take away the heat generated by the work of the magnetic therapy plate 201, realizes heat and cold exchange, and the efficient ventilation and heat dissipation can ensure that the magnetic therapy plate 201 is always at a suitable working temperature, operates stably, and avoids affecting the magnetic therapy effect due to overheating or shortening the service life of the magnetic therapy plate 201.

[0025] The working principle of the present invention: Place the magnetic therapy device on a stable place. The user sits on the cushion 102 of the base 100 and leans the back against the backrest cushion 200. By adjusting the rotating shaft 101 and the fixing cap inside the base 100, the backrest cushion 200 is fitted to the back curve of the user. Turn on the drive motor inside the backrest cushion 200. The output end of the motor drives the first gear 305 to rotate, and then the first rotating rod 301 rotates. The first rotating rod 301 drives the second rotating rod 303 to rotate synchronously through the synchronous belt 302. The bumps 304 on the synchronous belt 302 rotate to accurately massage the acupoints on the user's back. At the same time, the first gears 305 at both ends of the first rotating rod 301 rotate to drive the meshing second gears 403 to operate. The second gears 403 drive the power rods 402, and the power rods 402 push the pushing air plates 401 to reciprocate on the guiding slide rods 203, accelerating the air flow inside the backrest cushion 200, forming heat and cold exchange, and taking away the heat generated by the work of the magnetic therapy plate 201, ensuring the stable operation of the magnetic therapy plate 201. During the whole process, the sound insulation and ventilation plate 202 on the side of the backrest cushion 200 close to the magnetic therapy plate 201 shields the interference of the massage mechanism 300 on the magnetic therapy plate 201; the memory foam pad 204 on the outer side of the backrest cushion 200 provides comfortable support for the user.
