As we all know, the human body is a complex biological body full of microcirculation. Microcirculation is one of the basic characteristics of life, and it is an important way for the body and the surrounding environment to continuously carry out material, energy, and information transmission activities. People say that if the microcirculation is normal, there will be no stroke, if the microcirculation is good, there will be fewer myocardial infarctions, and if the microcirculation is smooth, there will be health and longevity. Therefore, improving microcirculation is an effective and necessary way to achieve human health care. At present, there are many ways to improve microcirculation, such as vasodilation drugs, blood circulation promoting and stasis drugs, acupuncture, qigong, physical therapy and physical therapy, etc. But there are very few methods that can really achieve home health care use, and are safe and have no side effects.

The human body can gradually improve the microcirculation of the human body during exercise, increase blood flow, and make the microcirculation smoother, so as to achieve the purpose of prolonging life. During exercise, the microcirculation of the human body will be subject to tiny disturbances from all directions of the outside world at any time. It is in this kind of continuous micro-disturbance that blood lipids will not be able to deposit and block capillaries like in a static state, and the blood lipids originally deposited in micro-vessels will also loosen in such micro-disturbances. If you persist in this disturbance and stimulation for a long time, the microcirculation will be improved considerably.

Therefore, there is a need for a device that can purposefully provide various mechanical vibrations for the human body to disturb the human body, so as to increase the blood flow and make the microcirculation of the human body more smooth.

Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

Fig. 1 is a side view of the health care chair provided by the present invention, including a chassis 1, a connector 2, a foot holder 3, a seat 4, a control button 5, a vibration direction control handle 6 and an upper body fixed baffle 7.

In the present invention, the connector 2 is a key component of the health care chair, and the connector 2 is a connecting part between the chassis 1 and the seat 4. The connector 2 drives the seat 4 to vibrate or rotate back and forth in various directions. The connector 2 can be designed as a cylindrical metal core, and a three-stage transmission mechanism as shown in FIG. 3 is arranged inside it.

As shown in FIG. 3 , the first-stage transmission structure includes a motor 8 , a connecting rod 9 , a connecting rod 10 and a slider 20 , which are used to complete the function of reciprocating vibration in a certain direction in the horizontal direction. The motor 8 is fixed on the chassis 2, and its shaft is fixedly connected with one end of the connecting rod 9. The other end of connecting rod 9 is rotatably connected with the front end of connecting rod 10 with a hinge. The end of the connecting rod 10 is rotatably connected to the slide block 20 with a hinge. The slider 20 is constrained by a chute (not shown) fixed on the chassis 2 to reciprocate in a certain horizontal direction. The setting of the chute for constraining the slider 20 is obvious, so the chute fixed on the chassis 2 is not shown in FIG. 3 . During work, the motor 8 drives the connecting rod 9 to rotate, the connecting rod 9 drives the connecting rod 10, and finally the connecting rod 10 drags the slider 20 to make the slider 20 reciprocate in the chute.

As shown in Figure 3, the second-stage transmission structure is fixed on the slider 20 as a whole, including a motor 17, a motor box 18, a transmission belt (or gear) 16 and a turntable 19 for completing the function of rotating in the horizontal direction. The motor box 18 is fixed on the slide block 20, and the motor 17 is placed in the motor box 18. The motor 17 and the turntable 19 are connected together by a transmission belt or a gear 16, and the rotating shaft of the turntable 19 is rotatably fixed on the slider 20 and can reciprocate with the slider 20. When working, the motor 17 drives the turntable 19 to rotate through the transmission belt 16 or the gear 16 , so that the turntable 19 can also perform rotational motion in addition to reciprocating vibration with the slider 20 .

As shown in FIG. 3 , the third stage transmission structure is fixed on the turntable 19 as a whole, including the motor 11 , the tripod 14 , the crankshaft 15 , the connecting rod 13 and the connecting rod 12 , and is used to complete the function of vibrating up and down. The motor 11 and the two tripods 14 are fixed on the turntable 19 and move with the turntable 19 . "Few" font crankshaft 15 is contained on two tripod supports 14. Connecting rod 13 is rotatably connected with crankshaft 15 with hinge, and connecting rod 13 is also rotatably connected with connecting rod 12 with hinge. The connecting rod 12 keeps the vertical direction, and is restricted by a chute fixed on the rotating disk 19 and can only move in the vertical direction. Likewise, the setting of the chute for constraining the connecting rod 12 is obvious, so the chute fixed on the turntable 19 is not shown in FIG. 3 . The upper end of the connecting rod 12 is fixedly connected with the seat 4 . When working, the motor 11 drives the crankshaft 15 to rotate between the two brackets 14, the crankshaft 15 drives the connecting rod 13 to swing, and the connecting rod 13 then pushes the connecting rod 12 connected thereto. Vibrate back and forth, so that the third-stage transmission structure makes the seat 4 connected to it vibrate up and down.

It can be known from the foregoing that the three-stage transmission structure respectively completes the functions of horizontal vibration, rotation and vertical vibration of the seat relative to the chassis. Each stage of the three-stage transmission structure is respectively fixed on the moving parts of the lower stage. Specifically, the second-stage transmission structure is fixed on the moving part slider 20 of the first-stage transmission structure, and the third-stage transmission structure is fixed On the moving parts turntable 19 of the second stage transmission structure. In this way, through the step-by-step transmission of the motion mode, the seat can finally move universally relative to the chassis 1 .

Due to the comprehensive effect of the three-stage transmission structure, the seat 4 will generate universal mechanical motion. Motors 8, 11 and 17 can adopt variable-speed motors with steplessly adjustable speed, and their speed can be controlled by the control button 5 or handle 6 (Fig. 2) arranged on the seat 4, so as to achieve the purpose of converting vibration mode and intensity. For example, the control button 5 can include a plurality of buttons, which are respectively responsible for the switch of the health care chair power supply, the rotation direction and the rotation speed of the motors 8 and 11, so as to control the start of the health care chair and the horizontal and vertical reciprocating vibration states of the seat 4. The handle 6 can adjust the direction of rotation and the speed of rotation of the motor 17, for example, the rotation state of the motor 17 can be controlled by the torque on the handle 6, so as to control the orientation of the seat 4 and the rotation state of the seat 4.

Between the slider 20 and the chute of the constraint slider 20, between the connecting rod 12 and the chute of the constraint link 12, balls or rollers can be added to change the sliding friction into rolling friction to reduce friction loss and noise and extend the service life. There is long-term high-strength friction between the slide block 20, the connecting rod 12 and the chute that constrain them, so they should be made of wear-resistant materials such as bearing steel.

In Fig. 1 and Fig. 2, the chassis 1 can be made of metal materials such as cast iron, its height should not be too high, and its mass should be large enough to lower the center of gravity of the whole device so as to ensure the stability of the whole device. The shape of the chassis 1 should be as smooth as possible without sharp edges and corners. In order to avoid electric leakage accidents, the chassis 1 should be kept grounded when the power is on, so as to ensure the safety of users. For safety reasons, the chassis 1 may also include a casing made of insulating material to avoid electric shock accidents. Most of the power supply and main power components should be in the chassis.

The seat surface and the backrest of the chair of seat 4 should be made into the shape of the human body surface in contact with it with sponge, when the health care chair vibrates, people will feel comfortable sitting on it. In order to make the human body feel stable when sitting on the seat, the seat surface should be slightly tilted back. Simultaneously for avoiding seat when vibrating, upper body can not rock, on the backrest, added the upper body fixed baffle plate 7 of an overturning type to avoid the rocking of upper body. As can be seen in Fig. 1, when the health care chair was started, the upper body fixed baffle 7 could be turned over to the front of the chair from behind, and the upper body of the human body was clamped therein so that it was fixed to achieve the purpose of protection. For avoiding the rocking of both feet, the foot fixer 3 of buckle shape has been added near the chair foot to fix both feet, so that both feet can not be shaken when vibrating. In the same way, for making the human body comfortable, the side where the upper body fixed baffle plate 7 presses the upper body of the human body should also be made of sponge. In order to completely protect the safety of the human body, the upper body fixed baffle 7 should have an interlocking device with the power switch of the health care chair. When the fixed baffle 7 is not turned to the front, the health care chair cannot be started. Plate 7 is tightly pressed against the human body and cannot be loosened. In order to reduce the energy consumption of the whole device, the seat 4 should adopt a lighter material or a material-saving structural design as far as possible under the premise of ensuring the firmness. You are not limited to the styles shown in Figures 1 and 2.

Simultaneously in order to avoid seat 4 action, the human body above is dangerous due to inertial movement or swing, on seat 4, foot anchor 3 and upper body fixed baffle plate 7 are added to ensure human body and seat 4 when health care chair starts bound together. Upper body fixed baffle 7 as shown in Figure 1, can be designed to flip type. During use, upper body fixed baffle plate 7 is turned over from seat 4 to the front together with the backrest. For safety considerations, the health care chair should be designed so that when the upper body fixed baffle 7 is not flipped to the front, the health care chair cannot be started, and the switch button does not work, so as to ensure that the human body must be fixed on the seat and cannot move arbitrarily when the health care chair is started .

In order to enable the user to have corresponding rhythmic music when vibrating, to achieve better entertainment and relaxation purposes, audio equipment can be built in the chassis 1, and its rhythm can match the state of the control button 5 and the vibration direction control handle 6 . According to the strength of the vibration, music with different rhythms is released.

When the health care chair of the present invention is in use, at first a general inspection is made to the device, and after confirming that there is no abnormality, sit on the seat 4, fix one's own feet on the seat with the foot fixer 3 by oneself, and fix the upper body The baffle plate 7 presses the user's upper body tightly. Select the vibration mode by the control button 5, such as slow, fast, or slow first and then fast, etc., and adjust the vibration direction with the direction control handle 6. After everything is confirmed, the user holds the armrest of the seat tightly with both hands, presses the start button, and starts to use. In order to ensure safety, it can be designed to press any button during use, and the device will stop working. If the user wants to change the vibration mode, he must stop the health care chair, select a good vibration mode in a static state, and then start the health care chair. The above sport modes can also be pre-programmed for subsequent selection.

The device provided by the invention can be used for general family health care and entertainment. It makes the human body vibrate in multiple directions, and under the continuous disturbance of the acceleration in multiple directions, the microcirculation system of the human body can be exercised. Regularly doing this kind of activity will not only make it difficult for the blood lipids in the human body to settle in the microvessels, but also loosen the deposited substances that are easy to block the capillaries. Moreover, the device is highly entertaining and can completely relax the body and mind of the human body so as to achieve the purpose of health care. In addition to being used at home, it can also be used as entertainment equipment in playgrounds. But because this device adopts the mode of vibrating to the human body, the user should be allowed to adapt to the low gear and choose the intensity that suits him. When the intensity increases, the increased gradient should not be too sharp, and the intensity should not increase suddenly, so as not to cause discomfort to the user. When children or the elderly use it, it is best to have someone to protect it. In case of danger, the plug can be unplugged to allow the health care chair to stop working.
