Description

Technical Field

[0001] This invention belongs to the field of massage chairs, specifically a massage chair suitable for full-body massage. Background Technology

[0002] A massage chair is a health care device that uses mechanical devices to simulate manual massage techniques to achieve effects such as relaxation and fatigue relief. It provides a full-body massage through back, arm, buttock, leg, and foot massage components installed on the chair. However, it still has the following drawbacks:

[0003] When elderly people use massage chairs, the massage targets their backs. Since the back is close to the lungs, the pressing and kneading motions during the massage produce slight vibrations. These vibrations are transmitted through the bones and muscles of the chest and back to the lungs and trachea. The vibrations loosen the phlegm attached to the walls of the trachea and bronchi, causing it to detach from the walls and move towards the throat. This may cause the elderly to cough up phlegm during the massage. Since phlegm is sticky, it is not easy to expel, which in turn affects the massage comfort due to the elderly's insufficient ability to expel phlegm. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, the present invention provides a massage chair suitable for full-body massage, which effectively solves the problems mentioned in the background art above.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. In this invention, when the groove on the tapping ring plate corresponds to the groove on the arc-shaped slide, the rubber massage head moves back and forth, which can squeeze and massage the back of the elderly. When the groove on the tapping ring plate is misaligned with the groove on the arc-shaped slide, the reciprocating movement of the rubber massage head can push the tapping ring plate to move back and forth, simulating the tapping of the palm, which makes it easier for the elderly to expel phlegm.

[0020] 2. In this invention, during back massage, the limiting airbag and the rear support airbag are connected and expand together. The expansion of the limiting airbag is to adjust the position of the moving plate and the massage tapping parts to make it suitable for elderly people of different body types. The expansion of the rear support airbag is to provide soft support for the elderly's back and improve the massage comfort.

[0021] 3. In this invention, the U-shaped frame and the L-shaped plate are fixed by the locking rod being inserted into the slot under air pressure. When the backrest is rotated forward to make the elderly person lean forward, the moving tube slides into the second air inlet slot to further fix the L-shaped plate. At the same time, it allows outside air to enter the front support airbag, causing the front support airbag to expand and provide chest support and protection for the elderly person, improving the comfort of sputum expectoration.

[0022] 4. In this invention, when the elderly person leans forward by rotating the backrest forward, the screw block moves due to gravity, causing the rotating baffle to rotate until the second through groove is misaligned with the first through groove. This ensures that the air pressure inside the limiting airbag is not affected after leaning forward, thus maintaining the position of the massage and tapping parts for easy tapping of the elderly person. At the same time, the through hole aligns with the ventilation groove, allowing air from the rear support airbag to enter the arc-shaped sliding groove, which in turn pushes the tapping ring plate to rotate and close the tapping ring plate to the rod groove on the arc-shaped sliding seat, facilitating tapping and sputum removal for the elderly person.

[0023] 5. In this invention, the air pressure sensor can detect the air pressure after inflation and control the opening and closing of the branch solenoid valve. When the branch solenoid valve in the second air inlet slot is closed, the controller controls the main solenoid valve to close and reduces the suction negative pressure of the air pump, so that the suction head can assist the elderly in suctioning sputum.

A main solenoid valve 75124 is installed on the air inlet pipe 752. An air pressure sensor 75112 can detect the air pressure after inflation and control the opening and closing of the auxiliary solenoid valve 75111. When the second air inlet slot 75... After the internal branch solenoid valve 75111 is closed, the controller controls the main solenoid valve 75124 to close, and reduces the suction negative pressure of the air pump 75121, so that the suction head 75123 can assist the elderly in suctioning sputum. The air pump 75121 circuit is electrically connected to a rheostat. The controller controls the resistance of the rheostat to change the current flowing through the air pump 75121, thereby changing the speed of the impeller inside the air pump 75121, and thus adjusting the suction negative pressure.

[0053] Working principle: When the elderly only need a massage, the two L-shaped plates 72 on the U-shaped frame 71 are set to the open position. When using it, the elderly sit on the seat cushion 2 and lean against the backrest 3. Their legs enter the leg massager 4, their feet enter the foot massager 5, and their hands enter the hand massager 6. The foot massager 5 massages the feet, and the leg massager 4 massages the calves. The seat cushion 2 is also equipped with a massage mechanism that can be installed on the elderly's buttocks and thighs. The hand massager 6 massages the elderly's arms. When the air pump 75121 is turned on, the limiting airbag 732 and the rear support airbag 733 inflate to support the elderly's back. The massage tapping piece 735 can massage the elderly's back, thereby achieving a full-body massage. In this state, there is no restriction on the elderly, ensuring massage comfort.

[0054] When the air pump 75121 is turned on, outside air is drawn into the internal cavity 753 through the air intake pipe 752, which generates pressure on the bottom of the piston block 754, thereby pushing the lever 756 to move upward, so that the bottom groove 755 is connected to the first air intake groove 758. At this time, outside air enters the inside of the limiting airbag 732 through the first air intake groove 758. At this time, the first through groove 7343 and the second through groove 7347 correspond to each other, allowing air to enter the rear support airbag 733, causing the limiting airbag 732 and the rear support airbag 733 to inflate, thereby supporting the elderly's back. When the air pressure in the internal space of the limiting airbag 732 and the rear support airbag 733 increases, the air pressure sensor 75112 located in the first air intake groove 758 detects the air pressure. When the air pressure reaches a certain value, the controller receives the signal and controls the solenoid valve 75111 to close.

[0055] During the massage, the electromagnet 73510 is continuously switched on and off by the controller. When energized, it attracts the magnetic block 7359, causing the rubber massage head 7357 to move outward. When de-energized, the magnetic block 7359 moves back under the repulsive force of the first spring 7358, causing the rubber massage head 7357 to move back and forth, squeezing and massaging the muscles of the elderly's back.

[0056] When the elderly person needs to clear phlegm after a massage, the air pump 75121 is shut off and the solenoid valve 75111 is opened to the connected state, expelling air from the limiting airbag 732 and the rear support airbag 733. The elderly person then rotates the two L-shaped plates 72 with both hands, moving them to the chest position. The air pump 75121 is then restarted, drawing outside air into the internal cavity 753 through the air inlet pipe 752. This creates pressure on the bottom of the piston block 754, pushing the locking rod 756 upwards. The locking rod 756 then inserts into the locking groove 759, securing the L-shaped plate 72. Finally, the cylinder is activated to rotate the backrest 3, shifting the elderly person from a reclining to a forward-leaning position. After the rotation:

[0057] On one hand, the moving tube 7573 slides outward under the action of gravity, so that the moving tube 7573 enters the second air inlet groove 7510. The outer wall of the moving tube 7573 is in close contact with the inner wall of the second air inlet groove 7510, and the longitudinal groove 7571 is opened, so that the air pump 75121 enters the front support airbag 74 from the second air inlet groove 7510, causing the front support airbag 74 to expand, supporting the elderly's chest and improving the comfort of the sputum expectoration process. When the air pressure sensor 75112 detects that the air pressure inside the front support airbag 74 has increased to a certain value, it closes the solenoid valve 75111.

[0058] On the other hand, the screw block 73411 slides along the screw barrel 73410 under its own weight and the weight of the counterweight rod 73412. The screw block 73411 is threadedly connected to the screw barrel 73410, causing the second through groove 7347 to rotate. When the second through groove 7347 is misaligned with the first through groove 7343, the limiting airbag 732 is isolated from the rear support airbag 733, ensuring the initial position of the massage tapping component 735. This facilitates tapping and spitting out phlegm for elderly people of different body types. At the same time, the through hole 7349 on the baffle 7348 corresponds to the ventilation groove 7345. At this time, the rear support airbag 733 moves back under its own elastic force, squeezing the air inside it into the arc-shaped slide groove 73511 through the ventilation groove 7345. This pushes the arc-shaped piston block 73513 to move, thereby driving the tapping ring plate 7353 to rotate, causing the tapping ring plate 7353 to rotate. 353 can close the rod groove 7354 on the arc-shaped slide 7352. At this time, the electromagnet 73510 is driven to intermittently switch on and off. When the rubber massage head 7357 moves outward, it pushes the patting ring plate 7353 to move outward. When the rubber massage head 7357 moves back, the patting ring plate 7353 can move back under the elastic force of the third spring 73517, so that the patting ring plate 7353 moves back and forth to pat and tap the back of the elderly, which can loosen the phlegm in the lungs and facilitate phlegm discharge. The patting ring plate 7353 is ring-shaped, which can simulate the ring-shaped patting surface formed when the palm is patted. At the same time, due to the retraction of the rear support airbag 733, the rear support airbag 733 no longer restricts the back of the elderly, so that the rear support airbag 733 and the front support airbag 74 will not clamp the elderly, ensuring the authenticity of the elderly when phlegm is discharged.

[0059] When the branch solenoid valve 75111 in the second air intake slot 7510 is closed, the controller detects the corresponding state and controls the main solenoid valve 75124 to close through the control program to ensure the support effect. At the same time, it reduces the current supplied to the air pump 75121, so that the negative pressure suction generated by the air pump 75121 is reduced to a smaller state. When the elderly perform sputum suction, after rotating the L-shaped plate 72 to the front of the chest, they hold the suction head 75123 in their hand and put one end of the suction head 75123 in their mouth. The smaller negative pressure is used to assist in the sputum suction operation without causing harm to the elderly and improving the sputum suction effect.

[0060] During use, the massage chair is controlled by issuing commands via remote control. The remote control has functions such as "massage", "expelling phlegm", "start", "pause", "ventilation" and "off", and these commands are all controlled by a program, making it convenient for the elderly to use.
