In implementing this technical solution, it was discovered that the prior art has at least the following problems:

[0004] During the rehabilitation care of disabled people such as the elderly, injured and disabled who have difficulty in moving, bathing has always been a problem. Most of the time, medical staff or family members simply wipe and clean the patients with a towel to prevent bedsores, ulcers and other phenomena on the patients' bodies. However, wiping with a towel cannot immerse the patient's entire body in a bath. There are still areas that cannot be wiped, which are prone to breeding bacteria and viruses, affecting the patient's physical comfort and not conducive to the patient's rehabilitation care.

[0011] Preferably: the lifting assembly also includes a secondary bevel gear meshed with the outside of the bevel gear frame, and the inner cavity of the secondary bevel gear is fixedly connected to a rotating shaft that rotates with the side frame, and is fixedly connected to the threaded rod, a threaded sleeve is threaded on the threaded rod, and the inner side of the threaded sleeve is fixedly connected to a connecting arm that slides with the side frame, and the bottom of the connecting arm is fixedly connected to a bed board used in conjunction with the box frame.

[0012] Preferably: the spoiler assembly also includes a single-head cylinder rotating on the base frame near both sides of the double-head cylinder, and the piston rod of the single-head cylinder is fixedly connected to a planetary bevel gear used in conjunction with the driving bevel gear, the outer side of the single-head cylinder is fixedly connected to a transfer bevel gear, and the transfer bevel gear is meshed with a differential bevel gear, and the top of the differential bevel gear is fixedly connected to a spoiler impeller used in conjunction with the spoiler cover through a fan shaft.

[0013] Preferably, a vertical groove for slidingly cooperating with the connecting arm is provided on the inner side of the side frame close to the box frame, and a leaking plate is embedded in the bed board and adopts a diamond grid state design, and a headrest made of silicone material is embedded on one side of the bed board.

[0014] Preferably, the side of the spoiler is provided with spoiler side holes, and the spoiler side holes are distributed in a circumferential divergent shape along the central axis of the spoiler; the top of the spoiler is provided with spoiler top holes, and the longitudinal axis of the spoiler top holes is distributed in an inwardly inclined and convergent shape.

[0015] Preferably: a placement plate is fixedly connected to the inner side of the box frame near the spoiler, and a sealing cover with a handle head is clamped on the top of the placement plate. The placement plate and the sealing cover are both annular in design, and both sides of the sealing cover are embedded with a flow-equalizing net with an arc design.

[0017] Preferably, reserved slots are provided around the bottom of the base frame, and movable wheels that penetrate and cooperate with the reserved slots are fixedly connected around the inner cavity of the base frame.

[0018] A method for operating a multifunctional rehabilitation bed includes the following steps:

[0019] Step 1: First start the double-headed cylinder to extend the two sets of main bevel gears and snap them into the bevel gear rack. Then start the servo motor to drive the bevel gear system to rotate, causing the four threaded rods to rotate, so that the threaded sleeves lift the bed plate to the predetermined height through the connecting arm.

[0020] Step 2: After the bed board is raised to a predetermined height, hot water for bathing is injected into the box frame to a specified level. The servo motor is then controlled to reverse, causing the bed board to reset to its initial position and pause. The patient lies flat on the drain board with his head resting on the headrest, and the bed board continues to move downward, allowing the hot water to submerge the body but the head to be exposed to the water due to the raised cushion to prevent drowning. After the bed board is in place, the servo motor is paused, the double-headed cylinder is closed, and the main bevel gear moves inward and out of the bevel gear frame, completing the reset.

[0021] Step 3: Subsequently, start the two single-head cylinders to move the two sets of planetary bevel gears inward to mesh with the drive bevel gears. Then start the servo motor to drive the planetary bevel gears to rotate, thereby driving the intermediate bevel gear and the differential bevel gear to rotate in a linked manner, so that the spoiler impeller rotates in the spoiler cover. The spoiler force generated by the impeller acts on the bathing hot water through the spoiler side holes and the spoiler top hole, forming a surging and slapping effect, simulating surfing water flow. Combined with manual rubbing, it ensures the patient's comfort during the bathing process.

[0022] Step 4: Before steaming and fumigation therapy, first raise the patient and the bed board to the initial position, let the residual water drip through the leak plate and wipe it dry, open the electric control valve of the drain pipe, and empty the waste water in the box frame into the liquid storage tank. Then, raise the bed board to the predetermined height, light mugwort or incense in the placement tray, cover it with a sealing cover, and let the smoke diffuse evenly through the flow-equalizing net. Start the turbulent impeller to generate turbulent force, so that the smoke acts on the patient's body through the turbulent side holes, turbulent top holes and leak plate, promotes absorption, and completes the therapy.

[0023] The multifunctional rehabilitation bed and the working method thereof of the present invention have the following advantages:

[0024] 1. This multifunctional rehabilitation bed is first driven by a servo motor to provide a unified driving source, and the meshing stroke between the two sets of main bevel gears and the four bevel gear racks is adjusted by a double-headed cylinder. Then, the driving bevel gear and the driven bevel gear successively drive the two sets of main bevel gears and the four bevel gear racks that are meshed in place to rotate. The four bevel gear racks drive the four threaded rods to rotate through the rotating shafts on the four sets of secondary bevel gears. The four threaded rods drive the bed board and the patient lying flat on the drain board to perform adaptive lifting and lowering adjustments through the connecting arms on the four sets of threaded sleeves, meeting the needs of medical staff or family members to add hot water for bathing into the box frame, and at the same time, the patient lying flat on the drain board of the bed board moves down to the box frame filled with hot water for bathing, and the hot water for bathing just covers the patient's body, providing a bathing function for the patient, improving the patient's comfort, and contributing to the patient's rapid recovery.

[0025] 2. This multifunctional rehabilitation bed first adjusts the meshing stroke between the driving bevel gear and the two sets of planetary bevel gears by two single-head cylinders, and then the servo motor drives the two sets of transfer bevel gears and differential bevel gears to rotate in succession through the meshed driving bevel gear and the two sets of planetary bevel gears. The two sets of differential bevel gears drive the two sets of spoiler impellers to rotate in the two sets of spoiler covers, and the hot bathing water added to the box frame is disturbed to the patient's body area through the spoiler side holes and spoiler top holes on the two sets of spoiler covers, creating a comfortable surfing environment for the patient's bathing care.

[0026] 3. This multifunctional rehabilitation bed is designed so that after the patient has finished bathing and the waste water in the box frame is drained, ignited mugwort, incense, etc. are added to the placement tray. The smoke generated by it is dispersed into the box frame through the flow-equalizing net. The turbulent force generated by the two sets of rotating turbulent impellers is then used to force the smoke generated by the ignited mugwort, incense, etc. to evenly pass through the leak plate to reach the patient's body, promote absorption, further accelerate the patient's recovery speed, and shorten the patient's recovery period.

[0049] The spoiler assembly also includes a single-head cylinder 61 that rotates on both sides of the chassis 1 near the double-head cylinder 44, and the piston rod of the single-head cylinder 61 is fixedly connected to the planetary bevel gear 62 used in conjunction with the drive bevel gear 42. The two single-head cylinders 61 adjust the meshing stroke between the drive bevel gear 42 and the two sets of planetary bevel gears 62. The outer side of the single-head cylinder 61 is fixedly connected to a transfer bevel gear 63, and a differential bevel gear 64 is meshed on the transfer bevel gear 63. The servo motor 41 then drives the two sets of transfer bevel gears 63 and the differential bevel gear 64 to rotate in succession through the meshed drive bevel gear 42 and the two sets of planetary bevel gears 62. The top of the differential bevel gear 64 is fixedly connected to a spoiler impeller 65 used in conjunction with the spoiler cover 66 through the fan shaft. , two sets of differential bevel gears 64 drive two sets of spoiler impellers 65 to rotate in two sets of spoiler covers 66, and the hot bath water added in the box frame 2 is disturbed to the patient's body area through the spoiler side holes 11 and the spoiler top holes 12 on the two sets of spoiler covers 66, creating a comfortable surfing environment for the patient's bathing care; after the patient finishes bathing and the bathing waste water in the box frame 2 is emptied, the burning mugwort, incense, etc. are added to the placement tray 13, and the smoke generated by it is emitted into the box frame 2 through the flow equalizing net 15, and then the turbulent force generated by the rotating two sets of spoiler impellers 65 is used to force the smoke generated by the burning mugwort, incense, etc. to evenly pass through the leak plate 9 to reach the patient's body, promote absorption, further accelerate the patient's recovery speed, and shorten the patient's recovery period;

[0050] The side of the spoiler 66 is provided with a spoiler side hole 11, and the spoiler side holes 11 are distributed in a circumferential divergent shape along the central axis of the spoiler 66, and the top of the spoiler 66 is provided with a spoiler top hole 12, and the longitudinal axis of the spoiler 66 is distributed inwardly inclined and gathered, which is beneficial to the turbulent force generated by the rotation of the spoiler impeller 65 from the spoiler side holes 11 and the spoiler top hole 12 distributed in different states. The turbulent flow treatment is performed on the bathing hot water or steam fumigation smoke in the box frame 2, so that it effectively acts on the patient's body; the box frame 2 A placement tray 13 is fixedly connected to the inner side near the spoiler 66. After the patient finishes bathing and the bathing waste water in the box frame 2 is drained, it is convenient to add burning mugwort, incense, etc., and a sealing cover 14 with a handle head is clamped on the top of the placement tray 13 to seal the placement tray 13 after the burning mugwort and incense are added.

[0051] like Figure 12-14 As shown, during the rehabilitation care of patients, it is necessary to frequently train the muscles of the patients' hands and feet, which is usually massaged by medical staff or family members, or the patients can get out of bed and use rehabilitation equipment to train by themselves, which is rather troublesome and cannot meet the rehabilitation needs of patients' hands and feet at the same time. At the same time, it also achieves the filtering effect of bathing wastewater. A pulling assembly used in conjunction with the liquid storage tank 17 is provided on the side frame 3, and the pulling assembly includes a guide member 71 fixed to the side frame 3. The inner cavity of the liquid storage tank 17 is slidably connected with a filter plate 72.

[0052] A method for operating a multifunctional rehabilitation bed includes the following steps:

[0053] Step 1: When the patient needs to be bathed, the double-headed cylinder 44 is first controlled to open and drive the two sets of main bevel gears 45 to extend synchronously and get stuck in the meshing part of the four bevel gear racks 46. Then the servo motor 41 is controlled to open and drive the double-headed cylinder 44 on the driven bevel gear 43 to rotate synchronously through the driving bevel gear 42. The double-headed cylinder 44 drives the four bevel gear racks 46 to rotate accordingly through the two sets of main bevel gears 45 that are meshed in place. The four bevel gear racks 46 drive the rotating shafts 52 on the four sets of secondary bevel gears 51 to rotate accordingly. The four rotating shafts 52 drive the threaded sleeves 54 on the four threaded rods 53 to move upward. The four sets of threaded sleeves 54 drive the bed board 56 to move up to a predetermined height through the four connecting arms 55.

[0054] After the bed plate 56 moves down into place, the servo motor 41 is first controlled to pause, and the double-headed cylinder 44 is then controlled to close and drive the two sets of main bevel gears 45 to move inward synchronously and disengage the meshing portion of the four bevel gear racks 46 to the initial position;

[0055] The two sets of planetary bevel gears 62 are driven by the two single-head cylinders 61 to rotate, and the two sets of transfer bevel gears 63 are driven by the two transfer bevel gears 63 to rotate. The two sets of spoiler impellers 65 on the two sets of differential bevel gears 64 rotate in the two sets of spoiler covers 66. The turbulent force generated by the rotation of the two sets of spoiler impellers 65 in the two sets of spoiler covers 66 is transmitted to the bathing hot water area in the box frame 2 through the spoiler side holes 11 and the spoiler top hole 12, forcing the bathing hot water in the box frame 2 to surge in turbulence, slap the patient's body with turbulence, create a water surfing effect, and then combined with the rubbing action of the medical staff or family members on the patient's body, the patient can remain in a comfortable state during the bathing.

[0056] Step 4: Before the patient needs to be fumigated with steam, the bed board 56 is first controlled to move the patient who has finished bathing up to the initial position. The water on the bed board 56 also drips into the box frame 2 through the leak plate 9. After the patient's body and the leak plate 9 on the bed board 56 are wiped clean, the electric control valves on the two drainage pipes 16 are opened, and the bathing waste water in the box frame 2 is discharged into the two sets of liquid storage tanks 17 through the two drainage pipes 16. After the bathing waste water in the box frame 2 is completely emptied, the bed board 56 is controlled to move up to the initial position. After the predetermined height is reached, the burning mugwort, incense, etc. are placed in the placement tray 13, and the sealing cover 14 is clamped. After the smoke generated by the burning mugwort, incense, etc. in the placement tray 13 is dispersed through the flow-equalizing net 15, similarly, the two sets of spoiler impellers 65 are controlled to rotate in the two sets of spoiler covers 66 to generate a turbulent force that passes through the turbulent side holes 11 and the turbulent top holes 12 and is transmitted to the smoke area in the box frame 2, forcing the smoke in the box frame 2 to pass through the leak plate 9 on the bed board 56 to reach the patient's body and be absorbed;

[0057] Step 5. When the bathing waste water in the box frame 2 is completely discharged into the two groups of liquid storage tanks 17 through the two drainage pipes 16, and when the patient needs rehabilitation training, the patient's hands grab the two groups of hand-pulled frames 77, and the patient's ankles pass through and are placed in the two groups of foot pull rings 78. Then, the patient's hands and feet apply downward pressure to the two groups of hand-pulled frames 77 and foot pull rings 78, and force the two support ropes 76 to pass through the two groups of guide members 71 to drive the two main ropes 75 to pull upward. The two main ropes 75 pulled upward drive the two groups of filter plates 72 to slide upward in the two groups of liquid storage tanks 17, and compress the two groups of damping springs 73. During the compression period, the two groups of damping springs 73 also generate reaction force on the two main ropes 75, and transmit it to the patient. The hands and feet of the patient are stretched and rehabilitated, and the two sets of filter plates 72 sliding up and down also filter the bathing wastewater in the two sets of liquid storage tanks 17 back and forth, providing convenience for subsequent wastewater treatment.

[0058] It should be noted that the specific models and specifications of the servo motor 41, double-head cylinder 44 and single-head cylinder 61 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be repeated in detail.

[0059] The power supply circuits of the servo motor 41 , the double-headed cylinder 44 and the single-headed cylinder 61 are clear to those skilled in the art and will not be described in detail here.

10. A method for operating a multifunctional rehabilitation bed, based on the multifunctional rehabilitation bed according to any one of claims 1 to 9, characterized in that: The steps include: Step 1: First, start the double-headed cylinder (44) to make the two sets of main bevel gears (45) extend outward and snap into the bevel gear frame (46), then start the servo motor (41) to drive the bevel gear system to rotate, drive the four threaded rods (53) to rotate, and make the threaded sleeve (54) lift the bed plate (56) to a predetermined height through the connecting arm (55); Step 2: After the bed board (56) is raised to a predetermined height, hot water for bathing is injected into the box frame (2) to a specified liquid level, and then the servo motor (41) is controlled to reverse, so that the bed board (56) is first reset to the initial position and paused. After the patient lies flat on the drain plate (9) and leans against the headrest (10), the bed board (56) continues to move downward, so that the hot water submerges the body but the head is exposed to the water surface due to the padding, to prevent drowning. After reaching the position, the servo motor (41) is paused, the double-headed cylinder (44) is closed, and the main bevel gear (45) moves inward and disengages from the bevel gear frame (46), completing the reset; Step 3: Subsequently, the two single-head cylinders (61) are started to move the two sets of planetary bevel gears (62) inwardly to engage with the driving bevel gear (42), and then the servo motor (41) is turned on to drive the planetary bevel gears (62) to rotate, thereby driving the intermediate bevel gear (63) and the differential bevel gear (64) to rotate, so that the spoiler impeller (65) rotates in the spoiler cover (66). The spoiler force generated by the impeller acts on the bathing hot water through the spoiler side hole (11) and the spoiler top hole (12), forming a surging and slapping effect, simulating surfing water flow, combined with manual rubbing, to ensure the patient's comfort during the bathing process; Step 4: Before steam fumigation therapy, the patient and the bed board (56) are first raised to the initial position, the residual water is allowed to drip through the leak plate (9) and wiped dry, the drain pipe (16) electric control valve is opened, and the waste water in the box frame (2) is emptied into the liquid storage tank (17), then the bed board (56) is raised to a predetermined height, wormwood or incense is lit in the placement tray (13), and the sealing cover (14) is covered. The smoke is evenly diffused through the flow-equalizing net (15), and the turbulent impeller (65) is started to generate turbulent force, so that the smoke acts on the patient's body through the turbulent side hole (11), the turbulent top hole (12) and the leak plate (9), promoting absorption and completing the turbulent therapy.
