Description

Technical Field

[0001] The present invention relates to the technical field of sports rehabilitation equipment, in particular to an underwater sports micro-hyperbaric oxygen chamber with a pressure self-regulating function. Background Art

[0002] Underwater high-pressure exercise rehabilitation is an emerging rehabilitation treatment method. It combines the buoyancy, resistance and high-pressure environment of water to provide patients with a unique rehabilitation training environment. The buoyancy of water can reduce body weight and reduce joint pressure. The human body moving in water is affected by the viscosity of water, which will produce three-dimensional resistance. Resistance training can be performed to enhance muscle strength and endurance, and improve movement stability. When the human body is immersed in water, it will be subjected to hydrostatic pressure, which can promote blood circulation and metabolism, increase venous return and lymph and tissue fluid return, help reduce edema, and is beneficial to patients with cardiovascular disease, post-traumatic swelling, etc. The underwater high-pressure environment can increase the oxygen content in the blood, improve tissue oxygen supply, promote metabolism, accelerate the repair of damaged tissues, and regulate nervous system function, relieve pain and muscle spasms.

[0003] Existing underwater rehabilitation equipment mainly focuses on underwater treadmills. This semi-open rehabilitation equipment ignores the positive role of micro-high pressure oxygen enrichment in rehabilitation, and also neglects the safety aspects of underwater sports rehabilitation. When trainees exercise underwater, there is a risk of falls and slips due to slipping and cramps. Even if the underwater treadmill is only above the waist, there is still a risk of choking and drowning. At the same time, slips and other accidents will cause secondary injuries due to bumps. Summary of the Invention

[0004] The purpose of the present invention is to provide an underwater sports micro-hyperbaric oxygen chamber with a pressure self-regulating function to solve the problems in the prior art.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: an underwater sports micro-hyperbaric oxygen chamber with a pressure self-regulating function includes a base, a cabin body, a control panel, a massage mechanism, an anti-fall mechanism and an auxiliary mechanism. The base is fixedly connected to the cabin body, the anti-fall mechanism and the auxiliary mechanism. A pulley foot is provided on the base, and the pulley foot is provided at the bottom of the base. The cabin body and the control panel are fixedly connected. A pressurization valve port and a pressure relief valve port are provided on the cabin body. The pressurization valve port, the pressure relief valve port and the massage mechanism are all connected to the control panel through electrical signals. The massage mechanism includes an arc table, and the arc table is fixedly connected to the anti-fall mechanism.

[0006] The present invention relates to a sealed oxygen chamber for underwater exercise. The control panel sends an electrical signal to a pressurization valve port and a pressure relief valve port, and oxygen is added or pressure is relieved in the chamber by controlling the opening and closing of the pressurization valve port and the pressure relief valve port, so that the environment in the chamber reaches a slightly high pressure and oxygen-rich state, which is beneficial to rehabilitation training. Water is injected into the chamber, and the trainee's waist is fixed by a massage mechanism, and the waist is continuously massaged to avoid the waist being tightly bound underwater and causing blood circulation obstruction. The massage mechanism is connected and assembled through an anti-fall mechanism to assist the trainee in completing the action in the underwater link. The trainee can complete rehabilitation training such as running in water, chest expansion and paddling in water, and hot spring stretching exercises on the auxiliary mechanism. At the same time, the anti-fall mechanism can detect and feedback the human body's movement posture. When the center of gravity of the waist deviates at a large angle, the anti-fall mechanism actively feedbacks and exerts force to pull back to avoid the trainee slipping in the water and getting injured.

[0007] Furthermore, the cabin is also provided with side windows, water inlets and drain outlets. The pressure valve port and the pressure relief valve port are both located on the top of the cabin, the water inlet and the drain outlet are both located on the bottom of the cabin, and the side windows are located on the side walls of the cabin.

[0008] The side windows installed on the side walls of the cabin are conducive to increasing the permeability of the cabin, and at the same time facilitate observation of the status of the trainees from the outside. Oxygen is added to the cabin by controlling the opening and closing of the pressurization valve. When the pressure in the cabin rises to the set pressure, water is injected into the cabin through the water inlet at the bottom of the cabin. After the exercise, the water in the cabin is drained through the drain port, and then the pressure is released through the pressure relief valve.

[0009] Furthermore, the massage mechanism also includes a ring shell, an arc slider, a first spring, a rounding mechanism and an adjustment mechanism. The anti-fall mechanism includes a return mechanism. The return mechanism includes a disc. The arc table is fixedly connected to the disc. The ring shell is fixedly connected to the arc slider. The arc slider is slidably connected to the arc table. The first spring is fixedly connected to the arc slider and the arc table. A hemispherical cavity is provided on the ring shell. Several groups of hemispherical cavities and rounding mechanisms are provided. Several groups of hemispherical cavities and rounding mechanisms are evenly distributed along the circumference of the ring shell. The rounding mechanism includes a rotating ball, which is movably connected to the hemispherical cavity. The adjustment mechanism includes a first motor and a servo cylinder. The first motor and the servo cylinder are connected to the control panel through electrical signals.

[0010] After entering the cabin, the auxiliary training personnel wear the massage mechanism, the training personnel wear the ring shell and fix it on the waist, and the arc slider fixes the ring shell. When the trainee rotates the body, the arc slider drives the arc slider to slide along the arc platform to squeeze the first spring. There are several groups of circumferentially evenly distributed rounding mechanisms in the hemispherical cavity on the ring shell. The trainee can send electrical signals to the first motor and servo cylinder of the adjustment mechanism through the control panel. The first motor adjusts the rotation speed of the rotating ball in the hemispherical cavity, and the servo cylinder adjusts the rounding radius of the rounding mechanism, thereby adjusting the massage strength and amplitude of the overall massage mechanism to adapt to the comfort level of the trainee and ensure that his waist will not be blocked due to long-term tight binding underwater.

[0011] Furthermore, the rounding mechanism also includes a spring disc, a ball head rod, a gear disc, a leather cover, a ring disc and a connecting column. A ring groove is provided on the rotating ball. The spring disc is rotatably connected to the ring groove. The spring disc is fixedly connected to the ball head rod and the connecting column. The gear disc is fixedly connected to the rotating ball. The leather cover is fixedly connected to the ring shell. The ball head rod is in contact with the leather cover. The ring disc is in contact with the connecting column. The output end of the servo cylinder is fixedly connected to the ring disc. The adjustment mechanism also includes a ring table, which is rotatably connected to the ring shell. A top ring groove is provided on the ring table, and the top ring groove is engaged with the tooth surface of the gear disc.

[0012] The first motor outputs a fixed-axis torque to the ring table, which engages with the tooth surface of the gear disc through the top ring tooth groove on the ring table, and transmits the torque to the gear disc, so that the rotating ball rotates in the hemispherical cavity. The ring groove of the rotating ball is assembled with a spring disc through rotation, and a ball head rod is assembled at one end of the spring disc. The rotating ball rotates, driving the ball head rod to roll into a circle in the leather cover, and the leather cover evenly distributed around the circumference performs a full-scale surround massage on the trainee's waist. Due to the spring force of the spring disc itself, the connecting column assembled at the other end of the spring disc contacts the ring disc, and the ring disc is driven to move away from the connecting column through the output end of the servo cylinder, so that the contact point between the ring disc and the connecting column is offset toward the center of the rotating ball. At this time, the ball head rod assembled at the other end is synchronously offset toward the center of the rotating ball, and the radius of the ball head rod rolling into a circle in the leather cover is reduced.

[0013] Furthermore, the adjustment mechanism also includes an assembly ring, the first motor and the servo cylinder are fixedly connected to the ring shell, and a side ring groove is also provided on the ring platform. The output end of the first motor is engaged with the tooth surface of the side ring groove, and the assembly ring is fixedly connected to the ring disk.

[0014] The trainee can send electrical signals to the first motor and servo cylinder of the adjustment mechanism through the control panel. The first motor outputs a fixed-axis torque to the ring table. The output end of the first motor engages with the tooth surface of the side ring tooth groove, and the ring table rotates on the ring shell. The output end of the servo cylinder drives the ring disk away from the connecting column, so that the contact point between the ring disk and the connecting column is offset toward the center of the rotating ball. The servo cylinder is reset, and the connecting column contacts the ring disk under the action of the spring force of the spring disc itself, completing the change of the radius of the rounding.

[0015] Furthermore, the anti-fall mechanism also includes a transverse movement module, a vertical movement module and an assembly frame. The transverse movement module is fixedly connected to the base, and the transverse movement module is slidingly connected to the vertical movement module and the assembly frame. The return mechanism also includes a second spring, and a convex plate is provided on the disc. The return mechanism is provided with two groups, and the two groups of second springs are respectively provided on opposite sides of the convex plate.

[0016] By cooperating with the transverse movement module and the vertical movement module, the specified displacement of the assembly frame in the two-axis plane can be completed, which can cooperate with the trainees' actions and assist the trainees in wearing the ring shell. The assembly frame is assembled with the arc table through the disc on the return mechanism. Two sets of second springs are respectively set on the opposite sides of its convex plate. The two sets of return mechanisms can follow the trainees' waist and turn within a certain degree of freedom. When a large turn is detected, that is, the trainees' center of gravity is unbalanced, the return mechanism actively compensates and returns to the center, which can effectively avoid the risks of trainees slipping, choking and drowning underwater.

[0017] Furthermore, the return mechanism also includes a second motor, an outer cylinder and a sensor. The second motor is fixedly connected to the assembly frame, one group of outer cylinders is rotatably connected to the assembly frame, another group of outer cylinders is fixedly connected to the disc, the convex plate is rotatably connected to the outer cylinder, the sensor is fixedly connected to the outer cylinder, the second spring is fixedly connected to the convex plate and the sensor, the sensor is connected to the second motor through an electrical signal, an outer ring tooth groove is provided on the outer cylinder, and the output end of the second motor is engaged with the tooth surface of the outer ring tooth groove.

[0018] When the trainee loses balance and is about to fall forward or backward, the convex plate rotates in the outer cylinder and quickly squeezes the second spring. A sensor is installed through the second spring. The sensor detects the large rotation of the convex plate and sends an electrical signal to the second motor. The second motor outputs a fixed-axis torque to the outer ring tooth groove. The output end of the second motor engages with the tooth surface of the outer ring tooth groove, causing the outer cylinder to rotate in the opposite direction of the rotation of the convex plate. After the convex plate is reset under the action of the spring force of the second spring, the second motor outputs a reverse torque to reset the outer cylinder and complete the active correction when the trainee loses balance and falls.

[0019] Furthermore, the auxiliary mechanism includes a seat, an armrest and a treadmill, and the seat, the armrest and the treadmill are all fixedly connected to the base.

[0020] The trainees can hold the handrails on the treadmill and run in the water, which can effectively reduce the burden on joints, enhance joint flexibility, exercise muscles throughout the body, and improve muscle endurance. Stopping the treadmill and holding the handrails to do chest expansion and paddling in the water can enhance chest muscle strength, shape chest lines, strengthen arm muscles, and improve body coordination. Sitting on the seats, pouring hot spring water into the cabin, and the trainees doing hot spring stretching exercises can promote blood circulation, relax muscles, and improve respiratory system function.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention designs a massage mechanism, which outputs a fixed-axis torque to the ring table through the first motor, so that the rotating ball rotates in the hemispherical cavity, drives the ball head rod to roll into a circle in the leather cover, and massages the waist. Due to the spring force of the spring disc itself, the connecting column assembled with the spring disc contacts the ring disc, and the servo cylinder drives the ring disc to move away from the connecting column. The contact point between the ring disc and the connecting column shifts toward the center of the rotating ball. At this time, the ball head rod synchronously shifts toward the center of the rotating ball, and the rolling radius of the ball head rod in the leather cover is reduced. The rotation speed and rolling radius of the rotating ball are adjusted, and then the overall massage strength and amplitude are adjusted to adapt to the comfort level of the trainee and ensure that the waist will not be blocked by blood circulation due to long-term tight binding underwater; the present invention designs a return mechanism. When the trainee's center of gravity is unbalanced and is about to fall forward or backward, the convex plate rotates in the outer cylinder to quickly squeeze the second spring, and the sensor sends an electrical signal to the second motor. The second motor outputs a fixed-axis torque to the outer ring tooth groove, so that The outer cylinder rotates in the opposite direction of the rotation of the convex plate. After the convex plate is reset under the spring force of the second spring, the second motor outputs a reverse torque to reset the outer cylinder, thereby completing the active correction when the trainee loses balance and falls, which can effectively avoid the risks of the trainee slipping, choking and drowning underwater. The auxiliary mechanism designed by the present invention can effectively reduce the burden on the joints, enhance the flexibility of the joints, and exercise the muscles of the whole body by holding the handrails on the treadmill. Stopping the treadmill to perform chest expansion and paddling in the water can enhance the strength of the chest muscles, shape the chest lines, strengthen the arm muscles, and improve the coordination of the body. Sitting on the seat, hot spring water is introduced into the cabin to perform hot spring stretching exercises, which can promote blood circulation, relax muscles, and improve the function of the respiratory system. The present invention can effectively assist the trainee to complete rehabilitation during underwater exercise, prevent the trainee from slipping, choking and drowning underwater, and massage the waist at the same time to ensure that the waist will not be blocked by blood circulation due to being tightly bound underwater for a long time.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, the present invention provides a technical solution of an underwater sports micro-hyperbaric oxygen chamber with a pressure self-regulating function, including a base 1, a cabin body 2, a control panel 3, a massage mechanism 4, an anti-fall mechanism 5 and an auxiliary mechanism 6. The base 1 is fixedly connected to the cabin body 2, the anti-fall mechanism 5 and the auxiliary mechanism 6. The base 1 is provided with a pulley foot 11, which is arranged at the bottom of the base 1. The cabin body 2 and the control panel 3 are fixedly connected. The cabin body 2 is provided with a pressurization valve port 22 and a pressure relief valve port 23. The pressurization valve port 22, the pressure relief valve port 23 and the massage mechanism 4 are all connected to the control panel 3 through electrical signals. The massage mechanism 4 includes an arc platform 43, and the arc platform 43 is fixedly connected to the anti-fall mechanism 5.

[0033] The present invention is a sealed oxygen chamber for underwater exercise. The control panel 3 sends an electrical signal to the pressurization valve port 22 and the pressure relief valve port 23. By controlling the opening and closing of the pressurization valve port 22 and the pressure relief valve port 23, oxygen is added or pressure is relieved in the cabin 2, so that the environment in the cabin 2 reaches a slightly high pressure and oxygen-rich state, which is conducive to rehabilitation training. Water is injected into the cabin 2, and the trainee's waist is fixed by the massage mechanism 4, and the waist is continuously massaged to prevent the waist from being tightly bound underwater and causing blood circulation problems. The massage mechanism 4 is connected and assembled through the anti-fall mechanism 5 to assist the trainee in completing the action in the underwater link. The trainee can complete rehabilitation training such as running in water, chest expansion and paddling in water, and hot spring stretching exercises on the auxiliary mechanism 6. At the same time, the anti-fall mechanism 5 can detect and feedback the human body's movement posture. When the center of gravity of the waist deviates at a large angle, it actively feedbacks and exerts force to pull back to prevent the trainee from slipping in the water and getting injured.

[0034] like Figure 1 、 Figure 2 As shown, the cabin body 2 is also provided with a side window 21, a water inlet 24 and a drain outlet 25. The pressure valve port 22 and the pressure relief valve port 23 are both located at the top of the cabin body 2, the water inlet 24 and the drain outlet 25 are both located at the bottom of the cabin body 2, and the side window 21 is located on the side wall of the cabin body 2.

[0035] The side windows 21 provided on the side walls of the cabin 2 are conducive to increasing the permeability of the cabin 2, and at the same time facilitate observation of the status of the trainees from the outside. Oxygen is added to the cabin 2 by controlling the opening and closing of the pressurization valve port 22. When the pressure in the cabin 2 rises to the set pressure, water is injected into the cabin through the water inlet 24 at the bottom of the cabin 2. After the exercise is completed, the water in the cabin is drained through the drain port 25, and then the pressure is released through the pressure relief valve port 23.

[0036] like Figure 4 、 Figure 5 As shown, the massage mechanism 4 also includes a ring shell 41, an arc slider 42, a first spring 44, a rounding mechanism 45 and an adjustment mechanism 46. The anti-fall mechanism 5 includes a return mechanism 54. The return mechanism 54 includes a disc 543. The arc table 43 is fixedly connected to the disc 543. The ring shell 41 is fixedly connected to the arc slider 42. The arc slider 42 is slidably connected to the arc table 43. The first spring 44 is fixedly connected to the arc slider 42 and the arc table 43. A hemispherical cavity 411 is provided on the ring shell 41. The hemispherical cavity 411 and the rounding mechanism 45 are each provided with several groups. Several groups of hemispherical cavities 411 and the rounding mechanism 45 are evenly distributed along the circumference of the ring shell 41. The rounding mechanism 45 includes a rotating ball 451, which is movably connected to the hemispherical cavity 411. The adjustment mechanism 46 includes a first motor 461 and a servo cylinder 462. The first motor 461 and the servo cylinder 462 are both connected to the control panel 3 through electrical signals.

[0037] After entering the cabin 2, the auxiliary training personnel wear the massage mechanism 4, and the training personnel wear and fix the ring shell 41 on the waist, and the arc slider 42 fixes the ring shell 41. When the trainee rotates his body, the arc slider 42 drives the arc slider 42 to slide along the arc platform 43 to squeeze the first spring 44. The hemispherical cavity 411 on the ring shell 41 is provided with several groups of circumferentially evenly distributed rounding mechanisms 45. The trainee can send an electrical signal to the first motor 461 and the servo cylinder 462 of the adjustment mechanism 46 by controlling the control panel 3. The first motor 461 adjusts the rotation speed of the rotating ball 451 in the hemispherical cavity 411, and the servo cylinder 462 adjusts the rounding radius of the rounding mechanism 45, thereby adjusting the massage strength and amplitude of the overall massage mechanism 4 to adapt to the comfort level of the trainee and ensure that his waist will not be blocked due to long-term tight binding underwater.

[0038] like Figure 4 、 Figure 5 As shown, the rounding mechanism 45 also includes a spring disc 452, a ball head rod 453, a toothed disc 454, a leather cover 455, a ring disc 456 and a connecting column 457. A ring groove 4511 is provided on the rotating ball 451. The spring disc 452 is rotatably connected to the ring groove 4511. The spring disc 452 is fixedly connected to the ball head rod 453 and the connecting column 457. The toothed disc 454 is fixedly connected to the rotating ball 451. The leather cover 455 is fixedly connected to the ring shell 41. The ball head rod 453 is in contact with the leather cover 455. The ring disc 456 is in contact with the connecting column 457. The output end of the servo cylinder 462 is fixedly connected to the ring disc 456. The adjustment mechanism 46 also includes a ring platform 463. The ring platform 463 is rotatably connected to the ring shell 41. A top ring tooth groove 4632 is provided on the ring platform 463. The top ring tooth groove 4632 engages with the tooth surface of the toothed disc 454.

[0039] The first motor 461 outputs a fixed-axis torque to the ring platform 463, which meshes with the tooth surface of the toothed disc 454 through the top ring tooth groove 4632 on the ring platform 463, and transmits the torque to the toothed disc 454, so that the rotating ball 451 rotates in the hemispherical cavity 411. The ring groove 4511 of the rotating ball 451 is assembled with a spring disc 452 through rotation. One end of the spring disc 452 is assembled with a ball head rod 453. The rotating ball 451 rotates, driving the ball head rod 453 to roll into a circle in the leather cover 455. The leather cover 455 evenly distributed on the circumference is used to press the waist of the trainee. The whole body performs an all-round surrounding massage activity. Due to the spring force of the spring disc 452 itself, the connecting column 457 assembled at the other end of the spring disc 452 contacts the ring disk 456, and the output end of the servo cylinder 462 drives the ring disk 456 to move away from the connecting column 457, so that the contact point between the ring disk 456 and the connecting column 457 is offset toward the center of the rotating ball 451. At this time, the ball head rod 453 assembled at the other end is synchronously offset toward the center of the rotating ball 451, and the radius of the ball head rod 453 rolling in the leather cover 455 is reduced.

[0040] like Figure 5As shown, the adjustment mechanism 46 also includes an assembly ring 464, the first motor 461 and the servo cylinder 462 are fixedly connected to the ring housing 41, and a side ring groove 4631 is also provided on the ring platform 463. The output end of the first motor 461 is engaged with the tooth surface of the side ring groove 4631, and the assembly ring 464 is fixedly connected to the ring disk 456.

[0041] The trainee can send an electrical signal to the first motor 461 and the servo cylinder 462 of the adjustment mechanism 46 by operating the control panel 3. The first motor 461 outputs a fixed-axis torque to the ring platform 463. The output end of the first motor 461 engages with the tooth surface of the side ring tooth groove 4631, and the ring platform 463 rotates on the ring shell 41. The output end of the servo cylinder 462 drives the ring disk 456 to move away from the connecting column 457, so that the contact point between the ring disk 456 and the connecting column 457 is offset toward the center of the rotating ball 451. The servo cylinder 462 is reset, and the connecting column 457 contacts the ring disk 456 under the action of the spring force of the spring disc 452 itself, thereby completing the change of the rounding radius.

[0042] like Figure 6 、 Figure 7 、 Figure 8 As shown, the anti-fall mechanism 5 also includes a transverse movement module 51, a vertical movement module 52 and an assembly frame 53. The transverse movement module 51 is fixedly connected to the base 1, and the transverse movement module 51 and the vertical movement module 52 and the assembly frame 53 are all slidably connected. The return mechanism 54 also includes a second spring 544, and a convex plate 5431 is provided on the disc 543. The return mechanism 54 is provided with two groups, and the two groups of second springs 544 are respectively provided on different sides of the convex plate 5431.

[0043] By cooperating with the transverse movement module 51 and the vertical movement module 52, the specified displacement of the assembly frame 53 in the two-axis plane can be completed, which can cooperate with the trainee's actions and assist the trainee in wearing the ring shell 41. The assembly frame 53 is assembled with the arc platform 43 through the disk 543 on the return mechanism 54. Two sets of second springs 544 are respectively arranged on the opposite sides of its convex plate 5431. The two sets of return mechanisms 54 can follow the trainee's waist and turn within a certain degree of freedom. When a large turn is detected, that is, the trainee's center of gravity is unbalanced, the return mechanism 54 actively compensates and returns to the center, which can effectively avoid the risk of trainees slipping, choking and drowning underwater.

[0044] like Figure 6 、 Figure 7 、 Figure 8As shown, the return mechanism 54 also includes a second motor 541, an outer cylinder 542 and a sensor 545. The second motor 541 is fixedly connected to the assembly frame 53, one group of outer cylinders 542 are rotatably connected to the assembly frame 53, another group of outer cylinders 542 are fixedly connected to the disc 543, the convex plate 5431 is rotatably connected to the outer cylinder 542, the sensor 545 is fixedly connected to the outer cylinder 542, the second spring 544 is fixedly connected to the convex plate 5431 and the sensor 545, the sensor 545 is connected to the second motor 541 through an electrical signal, an outer ring tooth groove 5421 is provided on the outer cylinder 542, and the output end of the second motor 541 is engaged with the tooth surface of the outer ring tooth groove 5421.

[0045] When the trainee loses balance and is about to fall forward or backward, the convex plate 5431 rotates in the outer cylinder 542 and quickly squeezes the second spring 544. The sensor 545 is assembled through the second spring 544. The sensor 545 detects that the convex plate 5431 has rotated significantly and sends an electrical signal to the second motor 541. The second motor 541 outputs a fixed-axis torque to the outer ring tooth groove 5421. The output end of the second motor 541 engages with the tooth surface of the outer ring tooth groove 5421 to make the outer cylinder 542 rotate in the opposite direction of the rotation of the convex plate 5431. After the convex plate 5431 is reset under the action of the spring force of the second spring 544, the second motor 541 outputs a reverse torque to reset and rotate the outer cylinder 542, thereby completing the active correction when the trainee loses balance and falls.

[0046] like Figure 6 As shown, the auxiliary mechanism 6 includes a seat 61 , an armrest 62 and a treadmill 63 , and the seat 61 , the armrest 62 and the treadmill 63 are all fixedly connected to the base 1 .

[0047] The trainees can run in the water while holding the handrail 62 on the treadmill 63, which can effectively reduce the burden on the joints, enhance the flexibility of the joints, exercise the muscles of the whole body, and improve muscle endurance. Stopping the treadmill 63 and holding the handrail 62 to perform chest expansion and paddling in the water can enhance the strength of the chest muscles, shape the chest lines, strengthen the arm muscles, and improve the coordination of the body. Sitting on the seat 61, hot spring water is injected into the cabin 2, and the trainees perform hot spring stretching exercises, which can promote blood circulation, relax muscles, and improve the function of the respiratory system.

[0048] The working principle of the present invention is as follows: oxygen is added through the pressurizing valve port 22 to raise the pressure in the cabin 2 to the set pressure, water is added through the water inlet 24, and after the exercise, water is drained through the drain port 25, and the pressure is released through the pressure relief valve port 23. The trainee wears the ring shell 41 and fixes it on the waist. When the body rotates, the arc slider 42 slides along the arc platform 43 to squeeze the first spring 44, and the first motor 461 outputs a fixed axis torque to the ring platform 463, which engages with the tooth surface of the toothed disc 454 through the top ring tooth groove 4632, so that the rotating ball 451 rotates in the hemispherical cavity 411, and the spring disc 4 One end of the spring disc 452 is equipped with a ball head rod 453, which drives the ball head rod 453 to roll into a circle in the leather cover 455 to massage the waist. Due to the spring force of the spring disc 452 itself, the connecting column 457 assembled at the other end of the spring disc 452 contacts the ring disk 456. The output end of the servo cylinder 462 drives the ring disk 456 to move away from the connecting column 457, so that the contact point between the ring disk 456 and the connecting column 457 is offset toward the center of the rotating ball 451. At this time, the ball head rod 453 is synchronously offset toward the center of the rotating ball 451. The ball head rod 453 is in the leather cover. The radius of the circle 455 is reduced, and the massage strength and amplitude of the overall massage mechanism 4 are adjusted to suit the comfort level of the trainee, ensuring that his waist will not be blocked by blood circulation due to long-term tight binding underwater. The trainee is assisted in wearing the ring shell 41, and the assembly frame 53 is assembled with the arc platform 43 through the disk 543 on the return mechanism 54. The two sets of return mechanisms 54 can follow the trainee's waist to turn within a certain degree of freedom. When a large turn is detected, that is, the trainee's center of gravity is unbalanced, the return mechanism 54 actively compensates and returns to the center, which can effectively avoid the trainee from slipping, choking and drowning underwater. The trainee runs in the water while holding the handrail 62 on the treadmill 63, which can effectively reduce the burden on the joints, enhance joint flexibility, exercise the muscles of the whole body, and improve muscle endurance. Expanding the chest and paddling in the water can enhance the strength of the chest muscles, shape the chest lines, strengthen the arm muscles, and improve body coordination. Sitting on the seat 61, hot spring water is introduced into the cabin 2, and the trainee performs hot spring stretching exercises, which can promote blood circulation, relax muscles, and improve respiratory system function.
