Description

Technical Field

[0001] This invention belongs to the field of massage chairs, specifically a massage chair. Background Technology

[0002] A massage chair is a home appliance designed to relieve fatigue and relax the mind and body. It provides a comfortable massage experience by simulating manual massage techniques. Through pressing and tapping, it precisely targets easily strained areas such as the shoulders, neck, and back, making it convenient for the elderly to relax their muscles. During the massage, a hot air blower is often used to further relax the muscles. Ideally, cupping should be performed after the massage for multiple relaxation effects. Therefore, there is a need for a massage chair that can provide both basic massage functions and the benefits of hot air blowing and cupping. Summary of the Invention

[0003] In view of the above situation and to overcome the defects of the prior art, the present invention provides a massage chair that effectively solves the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a massage chair, comprising a massage chair body, wherein a bushing is provided on the back of the massage chair body, the bushing is provided with mounting holes evenly distributed, and a massage mechanism is provided inside the bushing;

[0005] The massage mechanism includes a base located inside the bushing, which is fixedly mounted on the back of the massage chair. Multiple massage head assemblies are arranged in an array on the base, with each massage head assembly corresponding to a mounting hole.

[0006] The massage head assembly includes a fixed box, inside which a top massage component and an air pressure drive component are installed, and on the outer wall of the fixed box an air intake control component is installed.

[0007] The top massage component includes a piston block installed inside the fixed box. The piston block has a spherical limiting groove inside. A massage cupping module is provided inside the spherical limiting groove. A bottom groove is provided at the bottom end of the spherical limiting groove. A snap-fit ​​fixing module is provided inside the bottom groove. A fixing cylinder is fixedly installed at the bottom end of the piston block. The fixing cylinder is connected to the bottom groove.

[0008] The massage and cupping module includes a hemispherical massage head installed inside a spherical limiting groove. Rubber pads are provided on both the outer wall of the hemispherical massage head and the inner wall of the spherical limiting groove. The outer wall of the hemispherical massage head and the inner wall of the spherical limiting groove are tightly fitted together. A base plate is fixedly installed at the bottom end of the hemispherical massage head. A negative pressure cylinder is installed at the bottom end of the base plate. A rubber protrusion ring is provided at the end of the negative pressure cylinder away from the base plate. Through holes are evenly opened on the hemispherical massage head. Gears are symmetrically and coaxially installed on both sides of the hemispherical massage head. The gears are rotatably installed in a rotating groove. The rotating groove is symmetrically opened on both sides of the spherical limiting groove. A horizontal sliding groove is opened at the bottom end of the rotating groove. A toothed plate is slidably installed inside the horizontal sliding groove. The toothed plate is meshed with the gear. A screw is rotatably installed inside the horizontal sliding groove. The screw is threadedly connected to the toothed plate. One end of the screw is fixedly connected to the output shaft of the first motor. The first motor is fixedly installed inside the piston block.

[0009] The pneumatic drive component includes a piston plate movably installed inside a fixed box. Second rubber guide blocks are symmetrically installed on both sides of the piston plate. The second rubber guide blocks are slidably installed inside the second guide grooves, which are symmetrically opened on the inner walls of both sides of the fixed box. A support spring is fixedly installed at the bottom of the second rubber guide block. The bottom of the support spring is fixedly connected to the inner bottom wall of the second guide groove. A heat insulation plate is fixedly installed at the bottom of the piston plate. A heating coil is installed on the heat insulation plate. A piston cylinder is fixedly installed at the top of the piston plate. The outer wall of the piston cylinder is in close contact with the inner wall of the fixed cylinder. A communication control module is installed inside the piston cylinder.

[0010] The communication control module includes a fixed baffle that is fixedly installed on the top of the piston cylinder. The fixed baffle has a first arc-shaped through groove. A rotating baffle is rotatably installed below the fixed baffle. The rotating baffle is tightly attached to the fixed baffle. The rotating baffle has a second arc-shaped through groove.

[0011] The air intake control component includes a C-shaped tube fixedly installed on the side wall of the fixed box. The space formed between the piston block and the piston plate is connected to one end of the C-shaped tube, and the space formed between the piston plate and the inner bottom wall of the fixed box is connected to the other end of the C-shaped tube. A first valve is installed on the end of the C-shaped tube that is connected to the space between the piston block and the piston plate, and a second valve is installed on the end of the C-shaped tube that is connected to the space below the piston plate. An air intake pipe is installed in the middle of the C-shaped tube, and a connecting hose is connected to the air intake pipe. Multiple connecting hoses are respectively connected to multiple output branches on the same air pump. The air pump is installed on the massage chair body.

[0012] In massage mode, the top of the hemispherical massage head is positioned above the piston block, driving the rotating baffle to rotate continuously. This causes the first and second arc-shaped channels to alternately overlap and misalign. Simultaneously, the second valve is opened, and the air pump drives air into the space below the piston plate. When the first and second arc-shaped channels misalign, the air pressure at the bottom of the piston plate increases, thereby generating pressure on the human body from the hemispherical massage head. At the same time, the air is heated by the heating coil. After the first and second arc-shaped channels overlap, the heated air is discharged from the through-hole on the hemispherical massage head, achieving hot air blowing. Simultaneously, the air pressure below the piston plate decreases. Thus, during the alternating overlap and misalignment of the first and second arc-shaped channels, the hemispherical massage head reciprocates to generate pressure, achieving massage.

[0013] In cupping mode, the hemispherical massage head is driven to rotate within the spherical limiting groove until the negative pressure cylinder faces upward, causing the rubber protrusion at the end of the negative pressure cylinder away from the base plate to contact the skin. The first valve is opened, and the air pump drives air into the space between the piston block and the piston plate, causing the first and second arc-shaped through grooves to be misaligned. When the air pressure between the piston block and the piston plate increases, it drives the piston block to move upward, making the end of the negative pressure cylinder fit tightly against the skin on the back. At the same time, it pushes the piston plate and piston cylinder downward, creating negative pressure between the negative pressure cylinder and the skin, thus achieving the cupping effect.

[0014] Preferably, first rubber guide blocks are symmetrically installed on both sides of the piston block, and the first rubber guide blocks are slidably installed inside the first guide groove, which is symmetrically opened on the inner walls of both sides of the fixed box.

[0015] Preferably, the piston cylinder is symmetrically mounted with fixing plates at its top end, and each of the two fixing plates has a slot on the side away from each other.

[0016] Preferably, the snap-fit ​​fixing module includes side plates symmetrically installed on the bottom wall of the bottom groove. A side cylinder is installed on the side of the two side plates that are far apart from each other. A snap-fit ​​rod is movably installed inside the side cylinder. The snap-fit ​​rod is snapped into the slot. A pull rod is fixedly installed at the end of the snap-fit ​​rod that is far away from the side plate. One end of the pull rod extends through to the end of the side cylinder that is far away from the side plate. A first spring is installed between one end of the snap-fit ​​rod and the inner wall of the end of the side cylinder. A transverse sliding plate is fixedly installed at one end of the pull rod.

[0017] Preferably, a longitudinal plate is provided on the side of the transverse plate away from the side plate, and a connecting rod is provided between the longitudinal plate and the transverse plate. The two ends of the connecting rod are respectively hinged to the transverse plate and the longitudinal plate. The end of the connecting rod near the transverse plate is inclined upward. A pressure ball is fixedly installed at the top of the longitudinal plate. A sliding groove is provided in the longitudinal plate. Sliding frames are symmetrically installed on the inner bottom wall of the bottom groove. The longitudinal plate is slidably connected to the sliding frames through the sliding groove.

[0018] Preferably, a bottom cylinder is fixedly installed at the bottom end of the rotating baffle, and a sliding shaft is slidably installed on the inner side of the bottom cylinder. The sliding shaft is rotatably connected to the bottom end of the fixed box, and the bottom end of the sliding shaft is fixedly connected to the output shaft of the second motor. The second motor is fixedly installed at the bottom end of the fixed box.

[0019] Preferably, a connecting seat is fixedly installed between the fixed box and the base.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] (1) In this invention, when the hemispherical massage head is on top of the piston block and protrudes upward, it can massage the back of the elderly. At the same time, hot air is blown through the through hole on the hemispherical massage head to facilitate the relaxation of back muscles. When the hemispherical massage head is rotated to the negative pressure cylinder facing upward, cupping can be performed on the back to increase the diversity of back muscle relaxation.

[0022] (2) In this invention, air is driven into the space below the piston plate by an air pump, and the second arc-shaped through groove is driven by a second motor to alternately offset and overlap with the first arc-shaped through groove. When the second arc-shaped through groove is offset from the first arc-shaped through groove, the air pressure below the piston plate increases, causing the hemispherical massage head to exert pressure on the back muscles. When the second arc-shaped through groove overlaps with the first arc-shaped through groove, the air below the piston plate is discharged, causing the hemispherical massage head to intermittently exert pressure on the back muscles, thereby achieving a massage effect.

[0023] (3) In this invention, a heating coil is installed on the heat insulation plate below the piston plate. When the second arc-shaped through groove is misaligned with the first arc-shaped through groove, the incoming air is concentrated in the space below the piston plate and heated by the heating coil. After the second arc-shaped through groove overlaps with the first arc-shaped through groove, the hot air is discharged to blow hot air onto the back muscles, thereby improving the relaxation effect on the back muscles.

[0024] (4) In this invention, when air is driven by an air pump into the space between the piston block and the piston plate, the piston block is driven to move upward, so that the end of the negative pressure cylinder is in close contact with the skin on the back. On the other hand, the piston plate and the piston cylinder are pushed downward, so that negative pressure is generated between the negative pressure cylinder and the skin, thereby achieving the cupping effect.

[0025] (5) In this invention, when the hemispherical massage head is set upward, the locking rod is engaged with the fixing plate to engage and fix the piston block and piston plate, so that when air enters the space below the piston plate, a massage effect is achieved. When the hemispherical massage head is rotated downward, its outer wall generates pressure on the pressure ball, driving the locking rod to disengage from the fixing plate, so that the piston block and piston plate can move away from each other and cupping is achieved.

The first valve 4222 and the second valve 4223 are used to control the inlet position, so as to facilitate the execution of massage and cupping operations respectively.

[0048] The pneumatic drive component 424 includes a piston plate 4241 movably installed inside the fixed housing 421. Second rubber guide blocks 4242 are symmetrically installed on both sides of the piston plate 4241. The second rubber guide blocks 4242 are slidably installed inside second guide grooves 4243, which are symmetrically formed on the inner walls of both sides of the fixed housing 421. A support spring 42410 is fixedly installed at the bottom end of each second rubber guide block 4242, and the bottom end of the support spring 42410 is fixedly connected to the inner bottom wall of the second guide groove 4243. A piston cylinder 4244 is fixedly installed at the top end of the piston plate 4241. The outer wall of the piston cylinder 4244... When the air pump drives air into the space between the piston block 4231 and the piston plate 4241, it is in close contact with the inner wall of the fixed cylinder 4238. On the one hand, it drives the piston block 4231 to move upward, so that the end of the negative pressure cylinder 42353 is in close contact with the skin on the back. On the other hand, it pushes the piston plate 4241 and the piston cylinder 4244 to move downward, so that negative pressure is generated between the negative pressure cylinder 42353 and the skin, thereby achieving the cupping effect. The top of the piston cylinder 4244 is symmetrically equipped with a fixed plate 4245. The two fixed plates 4245 are provided with a slot 4246 on the side away from each other. The piston cylinder 4244 is equipped with a communication control module 4249.

[0049] The communication control module 4249 includes a fixed baffle 42491 fixedly installed on the top of the piston cylinder 4244. The fixed baffle 42491 has a first arc-shaped through groove 42492. A rotating baffle 42493 is rotatably installed below the fixed baffle 42491, and the rotating baffle 42493 is tightly fitted to the fixed baffle 42491. The rotating baffle 42493 has a second arc-shaped through groove 42494. A bottom cylinder 42495 is fixedly installed at the bottom end of the rotating baffle 42493. A sliding shaft 42496 is slidably installed on the inner side of the bottom cylinder 42495. The sliding shaft 42496 is rotatably connected to the bottom end of the fixed box 421. The bottom end of the sliding shaft 42496 is connected to the second motor 42497.

The air pump drives air into the space below the piston plate 4241, and the second motor 42497 drives the second arc-shaped through groove 42494 to alternately offset and overlap with the first arc-shaped through groove 42492. When the second arc-shaped through groove 42494 is offset from the first arc-shaped through groove 42492, the air pressure below the piston plate 4241 increases, causing the hemispherical massage head 42351 to exert pressure on the back muscles. When the second arc-shaped through groove 42494 overlaps with the first arc-shaped through groove 42492, the air below the piston plate 4241 is discharged, causing the hemispherical massage head 42351 to intermittently exert pressure on the back muscles, thereby achieving a massage effect.

[0050] A heat insulation plate 4247 is fixedly installed at the bottom of the piston plate 4241. A heating coil 4248 is provided on the heat insulation plate 4247. When the second arc-shaped through groove 42494 is misaligned with the first arc-shaped through groove 42492, the incoming air is concentrated in the space below the piston plate 4241 and heated by the heating coil 4248. After the second arc-shaped through groove 42494 coincides with the first arc-shaped through groove 42492, the hot air is discharged to blow hot air onto the back muscles, thereby improving the relaxation effect on the back muscles.

[0051] The snap-fit ​​fixing module 4237 includes side plates 42371 symmetrically installed on the bottom wall of the bottom groove 4236. Side cylinders 42372 are installed on the opposite sides of the two side plates 42371. A locking rod 42373 is movably installed inside the side cylinder 42372. A pull rod 42374 is fixedly installed at the end of the locking rod 42373 away from the side plate 42371. One end of the pull rod 42374 extends through to the end of the side cylinder 42372 away from the side plate 42371. The locking rod 42374... A first spring 42375 is installed between one end of 373 and the inner wall of the end of the side cylinder 42372. A transverse plate 42376 is fixedly installed at one end of the pull rod 42374. A longitudinal plate 42377 is provided on the side of the transverse plate 42376 away from the side plate 42371. A connecting rod 42379 is provided between the longitudinal plate 42377 and the transverse plate 42376. The two ends of the connecting rod 42379 are hinged to the transverse plate 42376 and the longitudinal plate 42377, respectively. 79 is inclined upward at one end near the transverse plate 42376. A pressure ball 42378 is fixedly installed at the top of the longitudinal plate 42377. A sliding groove 423710 is opened in the longitudinal plate 42377. Sliding frames 423711 are symmetrically installed on the inner bottom wall of the bottom groove 4236. The longitudinal plate 42377 is slidably connected to the sliding frame 423711 through the sliding groove 423710. The locking rod 42373 is inserted into the locking groove 4246. The hemispherical massage head 4235 When the piston is set to face upwards, the locking rod 42373 engages with the fixing plate 4245, securing the piston block 4231 and the piston plate 4241. This allows air to enter the space below the piston plate 4241, achieving a massage effect. When the hemispherical massage head 42351 rotates downwards, its outer wall exerts pressure on the pressure ball 42378, driving the locking rod 42373 to disengage from the fixing plate 4245. This allows the piston block 4231 and the piston plate 4241 to move away from each other, thus achieving cupping.

[0052] Working principle: Elderly people are prone to back muscle fatigue. They can use the massage chair body 1 to massage their backs at home. Because the multiple fixed boxes 421 arranged in the array correspond one-to-one with the multiple mounting holes 3 on the bushing 2, the top of the hemispherical massage head 42351 is located on the outside of the bushing 2 through the mounting holes 3. When the elderly person is lying or sitting on the massage chair body 1, the multiple hemispherical massage heads 42351 support the elderly person and contact the elderly person's back muscles. At the same time, the bushing 2 is equipped with a support airbag to provide auxiliary support for the elderly person. The massage chair body 1 can perform massage and cupping for the elderly person.

[0053] When a massage is needed, the elderly person changes into loose clothing that is convenient for massage. The controller then controls the second valve 4223 on multiple fixed boxes 421 to open and turns on the air pump, allowing outside air to enter the space below the piston plate 4241 through the C-shaped tube 4221.

[0054] In its original state, the second arc-shaped through groove 42494 on the rotating baffle 42493 and the first arc-shaped through groove 42492 on the fixed baffle 42491 are misaligned, causing air to enter and accumulate in the space below the piston plate 4241, increasing the air pressure below the piston plate 4241, thereby generating upward pressure on the hemispherical massage head 42351, which in turn exerts pressure on the back muscles, producing a massage effect. The locking rod 42373 engages with the locking groove 4246 on the fixed plate 4245, thereby locking and fixing the piston plate 4241 and the piston block 4231.

[0055] After a period of air intake, the second motor 42497 is turned on to drive the sliding shaft 42496 to rotate 180 degrees. The sliding shaft 42496 is slidably connected to the bottom cylinder 42495, thereby driving the rotating baffle 42493 to rotate 180 degrees, so that the second arc-shaped through groove 42494 coincides with the first arc-shaped through groove 42492. At this time, the air below the piston plate 4241 enters the bottom groove 4236 from the second arc-shaped through groove 42494 and the first arc-shaped through groove 42492, and finally blows to the back of the elderly through the through hole 42354, generating a hot air blowing effect. The bottom of the piston plate 4241 is equipped with a heat insulation plate 4247, and a heating coil 4248 is provided on the heat insulation plate 4247. When air gathers below the piston plate 4241, the air pressure is increased to massage, and the heating coil 4248 heats the air, which facilitates subsequent hot air blowing and improves the relaxation effect on the back muscles of the elderly.

[0056] The output shaft of the second motor 42497 is controlled to rotate intermittently by 180 degrees, so that the second arc-shaped through groove 42494 and the first arc-shaped through groove 42492 alternately stagger and overlap, thereby alternatingly performing massage and hot air blowing.

[0057] When the elderly need cupping, the first motor 42312 is turned on to drive the toothed plate 42310 to move. Since the toothed plate 42310 is meshed with the gear 4239, it drives the hemispherical massage head 42351 to rotate 180 degrees, so that the negative pressure cylinder 42353 on the hemispherical massage head 42351 is set upward. Then the elderly expose their back and lie on the massage chair body 1, so that the skin of the back is in close contact with the rubber protrusion 42355 of the negative pressure cylinder 42353 on each fixed box 421 away from the bottom plate 42352.

[0058] During the rotation of the hemispherical massage head 42351, the hemispherical massage head 42351 exerts pressure on the pressure ball 42378, pushing the longitudinal plate 42377 to move downward along the sliding frame 423711. Then, the connecting rod 42379 pulls the locking rod 42373 to disengage from the locking groove 4246, thereby separating the piston block 4231 from the piston plate 4241.

[0059] Then, the first valve 4222 is opened, connecting the C-shaped tube 4221 with the space between the piston block 4231 and the piston plate 4241. The air pump is then turned on, allowing air to be pumped into the space between the piston block 4231 and the piston plate 4241 in each fixed box 421. As the air pressure between the piston block 4231 and the piston plate 4241 increases, it exerts pressure on the piston block 4231, causing the rubber protrusion 42355 of the negative pressure cylinder 42353, away from the bottom plate 42352, to press tightly against the elderly person's back skin, achieving a seal. Simultaneously, it pushes... Piston plate 4241 moves downward, wherein the second arc-shaped through groove 42494 on rotating baffle 42493 and the first arc-shaped through groove 42492 on fixed baffle 42491 are misaligned. When piston plate 4241 moves downward, it drives piston cylinder 4244 to move downward. Since bottom groove 4236 is connected to the inner cavity of hemispherical massage head 42351 through through hole 42354, when piston cylinder 4244 moves downward, negative pressure is generated between negative pressure cylinder 42353 and the skin on the back of the elderly, thereby achieving the effect of cupping.
