[0002] In people's daily lives, hand joints and leg joints are prone to fatigue due to high labor intensity. By massaging the painful areas manually, people will feel the pain relieved or disappear. Therefore, people often use massage devices to replace manual techniques to relax joints in daily life. Knee massage devices can relieve muscle spasms around the knee joint, improve joint blood circulation, eliminate inflammatory edema and congestion of knee joint soft tissues, enhance the strength and intensity of muscles around the knee joint, and inhibit the calcification or ossification process of the knee joint capsule and ligaments.

[0003] For example, the patent with the publication number CN219090119U discloses a knee joint massage and physiotherapy device, including a housing. Both sides inside the housing are provided with placement grooves. One side of each of the two placement grooves is fixedly connected with a first airbag, and one side of each of the two placement grooves is fixedly connected with a third airbag. One side inside each of the two first airbags is fixedly connected with a fixing block, and a spring is fixedly connected inside the fixing block. Through the setting of the adjusting pad in the present invention, when the legs are placed in the placement grooves, the adjusting pad can be adjusted in angle to enable adjustment of other postures for massage, preventing the user from feeling fatigued due to maintaining the same posture for a long time.

The outer shell 1 is a square structure, and the outer walls at both ends of the outer shell 1 have handle grooves 2, through which the device can be carried. U-shaped grooves 3 are respectively opened on both sides of the bottom of the outer shell 1, and the U-shaped grooves 3 are used to clamp the user's legs. An adjusting air cavity 11 is arranged on the side wall of one end of the U-shaped groove 3, and a restraining air cushion 31 is fixedly connected to the side wall of the U-shaped groove 3 outside the port of the adjusting air cavity 11, and a connected air guide valve tube is fixedly connected to the outer wall of one side of the adjusting air cavity 11 12, the end of the air guide valve tube 12 extends to the inside of the outer shell 1 and is connected to the regulating air pump 13, the regulating air pump 13 inflates and exhausts the restraining air cushion 31 through the air guide valve tube 12 and the regulating air cavity 11, a control host 15 is arranged on the inner wall of the outer shell 1 above the U-shaped groove 3, and dust-proof and heat-dissipating holes are evenly opened on the side walls of the outer shell 1 on both sides of the control host 15, a touch screen 16 is embedded on the top of the outer shell 1, the touch screen 16 is electrically connected to the control host 15, and a strap 17 is fixedly connected to the edge of one end of the bottom of the outer shell 1, and a limit buckle 18 is fixedly connected to the bottom of the side wall of the other end of the strap 17, and the end of the strap 17 is rolled up inside the limit buckle 18.

[0031] The limiting buckle 18 includes a mounting shell 181 fixedly connected to the bottom of the side wall at the end of the outer shell 1, and a rotating shaft 182 movably arranged on the inner walls at both ends of the mounting shell 181. A winding roller 183 is fixedly connected to the end of the rotating shaft 182. The movable end of the fixing strap 17 wound on the outer wall of the winding roller 183 passes through the bottom port of the outer shell 1. On the inner walls at both ends of the mounting shell 181 outside the rotating shaft 182, positioning cylinders 184 are respectively fixedly connected. A hairspring 185 is fixedly connected to the outer wall of the rotating shaft 182 inside the positioning cylinder 184. The outer end of the hairspring 185 is fixedly connected to the inner wall of the positioning cylinder 184. On one side of the inner wall at the bottom port of the mounting shell 181, a convex tooth limiting block 186 is fixedly connected. On the outer wall on the other side at the bottom port of the mounting shell 181, a spring rod 187 is fixedly connected. An installation frame is fixedly connected to the end of the spring rod 187.

After releasing the strap 17, the pinch roller 188 squeezes the strap 17 through the push of the spring rod 187 and puts it on the teeth on the end outer wall of the convex tooth limiting block 186, thus automatically completing the binding of fixing the massager on the user's leg, which is very convenient to use.

[0032] In order to solve the problem that the existing massager has too single massage function and its massage effect is difficult to fully soothe and relax the joints of the user, please refer to Figures 1 - 6 and provide the following preferred technical solutions:

[0033] Electromagnetic patch 314 is evenly and spacedly fixedly connected to the outer wall of the restraint air cushion 31, and massage rollers 4 are evenly and spacedly fixedly connected to the inner wall of the restraint air cushion 31. The massage rollers 4 are evenly distributed around the inner wall of the U-shaped groove 3.

[0034] The massage roller 4 includes fixing plates 41 evenly and spacedly fixedly connected to both sides of the inner wall of the restraint air cushion 31 and a rotating roller 42 movably arranged between the side walls of the corresponding fixing plates 41. Positioning shafts are fixedly connected to the outer walls at both ends of the rotating roller 42. The ends of the positioning shafts movably penetrate through the fixing plates 41. Massage bumps 43 are evenly and spacedly fixedly connected to the arc-shaped outer wall of the rotating roller 42. A driving gear 44 is fixedly connected to the outer wall of the positioning shaft at one end of the rotating roller 42. A chain 5 is sleeved on the outer wall of the driving gear 44. One end of the chain 5 extends into the adjustment air cavity 11. A micro motor 14 is fixedly connected to the inner wall of the adjustment air cavity 11. A driving gear is fixedly connected to the outer wall of the transmission shaft of the micro motor 14. The driving gear is sleeved with the chain 5 extending into the adjustment air cavity 11.

[0035] The massage bumps 43 on the outer arc wall of the rotating roller 42 are of hemispherical structure. The diameters of the massage bumps 43 arranged in a circle around the rotating roller 42 are arranged at uniform intervals from large to small. The massage bumps 43 of the same diameter are horizontally arranged in a row on the outer arc wall of the rotating roller 42. And a limiting rod 45 is fixedly connected to the outer wall of the fixing plate 41 on one side of the driving gear 44. After the chain 5 is sleeved on the outer wall of the driving gear 44 and arranged around the U-shaped groove 3, the lower end of the chain 5 is lapped on the top end of the limiting rod 45 on the outer wall of the fixing plate 41.

[0036] The rotating roller 42 is of a hollow structure. A positioning sleeve 421 is fixedly connected to the inner wall at one end of the inner cavity of the rotating roller 42. A moving rod 422 is movably penetrated through the top of the positioning sleeve 421. A counterweight slider 423 is fixedly connected to the top of the moving rod 422. A support spring 424 is fixedly connected between the counterweight slider 423 and the positioning sleeve 421. The bottom edge on the other side of the counterweight slider 423 is movably connected to the outer wall of the adjusting rod 426. A support rod is fixedly connected to the outer wall of the adjusting rod 426 at uniform intervals. The end of the support rod is arranged in contact with the inner wall of the inner cavity of the rotating roller 42. And an installation ring is fixedly connected to the outer wall of the adjusting rod 426 at uniform intervals between the support rods. The second connecting rod 427 is movably connected to the outer circumferential wall of the installation ring at uniform intervals. The end of the second connecting rod 427 is movably connected to the massage rod 428. A guiding channel 429 is opened on the outer wall of the rotating roller 42 corresponding to the massage rod 428. The massage rod 428 is movably inserted into the guiding channel 429.

[0037] The end of the massage rod 428 is of a spherical structure. The massage rod 428 is arranged corresponding to the massage bumps 43 on the outer wall of the rotating roller 42. The guiding channel 429 is opened on the outer wall of the rotating roller 42 between every two adjacent rows of massage bumps 43. And when the support spring 424 maintains a normal diastolic state, the counterweight slider 423 is arranged in contact with the inner wall of the inner cavity of the rotating roller 42. At this time, the spherical head of the massage rod 428 retracts into the guiding channel 429.

[0038] The restraining air cushion 31 includes an airbag cushion 311 fixedly connected to the inner wall of the U-shaped groove 3 outside the port of the regulating air cavity 11 and a conductive cloth 312 fixedly bonded to the outer wall of the airbag cushion 311 at uniform intervals. The conductive cloth 312 is electrically connected to the control host 15 through a cable. An elastic cloth cover 313 is fitted on the outer wall of the conductive cloth 312. Electromagnetic stone patches 314 are fixedly connected to the outer wall of the elastic cloth cover 313 at uniform intervals. The fixed end of the electromagnetic stone patch 314 is connected to a conductive strip 315. The conductive strip 315 extends to the inner side of the elastic cloth cover 313 and is fixedly connected to the outer wall of the conductive cloth 312. The control host 15 transfers electrical energy to the conductive cloth 312, and then turns on the electromagnetic stone patch 314 through the conductive cloth 312 and the conductive strip 315. After the electromagnetic stone patch 314 is energized, a magnetic field is generated to perform magnetic therapy on the user's legs, and the electromagnetic stone patch 314 generates a certain amount of heat to simultaneously perform hot compress on the user's legs, thereby enhancing the physical therapy effect on the user's knee joints.

[0039] Specifically, the user inserts the knee joint of the leg into the U-shaped groove 3 and binds it, then lays the leg flat, turns on the device, and adjusts the air pump 13 to inflate the restraint air cushion 31 through the air guide valve tube 12 and the regulating air cavity 11. After the restraint air cushion 31 is inflated, it fully wraps the knee joint, and the electromagnetic stone patch 314 is attached to the leg skin. After the electromagnetic stone patch 314 is energized, magnetic therapy is performed on the knee joint to relieve the knee joint muscles. Then, the micro motor 14 is started and cooperated with the chain 5 to drive the massage roller 4 inside the restraint air cushion 31 to rotate. When the massage roller 4 rotates through the rotating roller 42, it drives the uneven massage protrusions 43 on its outer wall to roll and massage the user's legs. At the same time, when the rotating roller 42 rotates slowly, every time the counterweight slider 423 rotates When the first connecting rod 425 approaches to the horizontal, it gradually pushes the adjusting rod 426 to move horizontally inside the rotating roller 42. When the adjusting rod 426 moves horizontally, it pushes the second connecting rod 427 to squeeze the massage rod 428, so that the massage rod 428 extends out of the port of the guide channel 429 when the massage rod 428 rotates. Therefore, when the rotating roller 42 and the massage protrusion 43 perform rolling massage on the user's legs, a beating massage is performed simultaneously, and the user's knee joints are massaged synchronously from multiple directions, which greatly enhances the massage therapy effect on the knee joints.

[0040] In order to further enhance the massage effect on the user's knee joint, Figure 7 and Figure 8 As shown, this embodiment provides the following technical solutions:

[0041] A movable pad 6 is fixedly connected to the top edge of the U-shaped groove 3 on one side of the restraining air cushion 31 , and positioning rings 7 are evenly spaced and embedded on the side wall of the movable pad 6 , and a moxibustion tube 8 is movably sleeved in the positioning rings 7 .

[0042] The moxibustion cylinder 8 includes a heat preservation sleeve 81 movably sleeved in the positioning collar 7 and an upper cover 82 movably covering the outer wall of the top port of the heat preservation sleeve 81. Air inlet holes 811 are evenly spaced on the side wall below the top port of the heat preservation sleeve 81. A elastic cord 821 is fixedly connected to the lower end of the top plate of the upper cover 82, and a moxa stick 822 is fixedly connected to the bottom of the elastic cord 821. The moxa stick 822 is of a cylindrical structure. A lower cover 83 is movably sleeved on the outer wall of the bottom port of the heat preservation sleeve 81. The lower cover 83 is of an annular structure. An annular ash receiving groove is formed at the top of the lower cover 83. An annular buffer inclined plate is fixedly connected to the inner wall of the top port of the annular ash receiving groove. Elastic members 84 are evenly spaced and fixedly connected to the inner wall of the middle hole of the lower cover 83. The end of the elastic member 84 is fixedly connected to a ceramic heat conduction column 85. The top of the ceramic heat conduction column 85 is fixedly connected to a ceramic microporous filter disc 86. The lower end of the moxa stick 822 is lapped on the top of the ceramic microporous filter disc 86. The ceramic microporous filter disc 86 is suspended above the port of the annular ash receiving groove.

[0043] An annular plate 87 is fixedly connected to the inner wall of the heat preservation sleeve 81 below the air inlet holes 811. Fixed springs 88 are evenly spaced and fixedly connected to the bottom of the annular plate 87. A clamping rod 89 is fixedly connected to the bottom of the fixed spring 88. The clamping rods 89 are annularly distributed outside the moxa stick 822. The top of one of the clamping rods 89 is fixedly connected to a pressing block 891. A pressing rod 892 is fixedly connected to the bottom of the pressing block 891. The pressing rod 892 penetrates through the clamping rod 89 and extends to its bottom. The bottom of the pressing rod 892 is close to the edge of one side of the ceramic microporous filter disc 86 suspended on the top.

[0044] Specifically, after opening the upper cover 82, insert the moxa stick 822 into the placement sleeve at the bottom of the elastic cord 821. After lighting the moxa stick 822 and placing it in the heat preservation sleeve 81, re-cover the upper cover 82. Then, screw the heat preservation sleeve 81 into the threaded hole of the positioning collar 7 on the outer wall of the movable pad 6 by using the threads on its outer wall, so that the lower end of the ceramic heat conduction column 85 in the middle hole of the lower cover 83 at the bottom end of the heat preservation sleeve 81 fits against the skin of the user's leg. The moxa stick 822 stretches by dragging the elastic cord 821 due to gravity, making its lit end contact and overlap on the top of the ceramic micro-hole filter disc 86. The ceramic micro-hole filter disc 86 holds up the moxa stick 822 with the sharp cone at the top. The moxa stick 822 conducts heat through the ceramic micro-hole filter disc 86 and the ceramic heat conduction column 85, and then uses the ceramic heat conduction column 85 to thermally moxibust the skin at the user's knee joint. At the same time, the hot air emitted by the moxa stick 822 penetrates through the air filter micro-holes of the ceramic micro-hole filter disc 86 and thermally moxibusts the user's skin through the middle hole of the lower cover 83. After thermally moxibusting for a period of time, the user shakes and lifts the leg and then puts it down, which promotes the vibration of the fixed spring 88 on one side of the bottom of the annular plate 87 driven by the pressing block 891. After the fixed spring 88 vibrates, the corresponding clamping rod 89 slides up and down on the outside of the moxa stick 822. When the clamping rod 89 moves downward, it drives the extrusion rod 892 to squeeze one side edge of the top of the ceramic micro-hole filter disc 86, causing the ceramic micro-hole filter disc 86 to tilt and deflect in the middle hole of the lower cover 83 based on the ceramic heat conduction column 85. After the ceramic micro-hole filter disc 86 tilts, the ashes accumulated by the burning and dropping of the moxa stick 822 on its top will automatically slide into the annular ash receiving groove on the top of the lower cover 83, thus promoting the full combustion of the remaining moxa stick 822 and avoiding the influence of the ashes on the combustion temperature of the moxa stick 822, thereby ensuring the thermal moxibustion effect on the user's knee joint of the moxa stick 822. After the massage is over, just unscrew the lower cover 83 and clean it, which is convenient to use.
