Description

Technical Field

[0001] The invention belongs to the technical field of physical therapy equipment, and in particular relates to a physical therapy device. Background Art

[0002] When a newborn has digestive problems such as bloating and constipation, doctors usually use gentle manual abdominal massage to help relieve the baby's discomfort. The doctor will gently place his hands on the baby's soft abdomen and perform a slow and rhythmic circular massage in a clockwise direction. This massage method is designed to gently stimulate intestinal peristalsis and promote gas discharge, thereby relieving abdominal pain and bloating caused by indigestion. It does not require any complex instruments, and the doctor can perform the operation accurately with only his own hands and rich clinical experience. During the massage, the doctor will concentrate on observing the baby's reactions, such as the degree of crying, body twisting, changes in facial expressions, etc. If the baby cries too violently, the doctor will immediately adjust the intensity of the massage to make it gentler to ensure that the baby does not feel excessive discomfort due to the massage. At the same time, the doctor will also adjust the speed of the massage according to the baby's reaction to ensure that the massage can achieve the therapeutic effect without making the baby feel fear and resistance.

[0003] However, manual massage also has some obvious limitations. Doctors often have a very heavy workload. In addition to doing various examinations for children, they also have to carry out a variety of medical activities such as drug treatment and physical therapy. In their daily work, doctors are already very busy. When encountering a high incidence of gastrointestinal diseases, such as when the seasons change, the number of patients will increase significantly, and doctors need to perform manual massage treatments for many children. Long-term, high-intensity manual massage operations make doctors' hands, wrists, and even the entire upper limbs prone to fatigue, muscle soreness, and may even cause occupational diseases such as tenosynovitis. Moreover, due to the limited energy and physical strength of doctors, as the massage time increases, the stability of the technique and the accuracy of the strength will be affected, which in turn affects the treatment effect. Summary of the invention

[0004] In view of this, the present invention provides a physical therapy device to solve the problem of high labor intensity and low efficiency in the prior art that doctors manually massage the abdomen of newborns.

[0005] The technical solution adopted by the present invention is as follows: A physiotherapy device comprises a base plate, wherein a plurality of through slots are arranged at equal intervals around the center of the base plate, a frame is arranged in each of the through slots, a massage wheel is rotatably connected in the frame, and the side wall of the massage wheel is lower than the bottom of the base plate; a shell is arranged around the top of the base plate, and the top of the shell is rotatably connected to a top plate via a connecting shaft; a first motor and a transmission device are also arranged on the top plate, and the transmission device transmission-connects the output shaft of the first motor with the connecting shaft, and when the output shaft of the first motor rotates, the connecting shaft can be driven to rotate forward and reverse reciprocatingly through the transmission device.

[0006] In this technical solution, it should be noted that the physiotherapy device of this solution has the function of reciprocating alternating rolling massage, that is, the first motor can drive its own output shaft to rotate, and after the output shaft rotates, the unidirectional rotational motion of the output shaft is converted into the alternating rotational motion of the connecting shaft (that is, clockwise rotation and counterclockwise rotation are performed reciprocatingly) through the transmission device, thereby driving the bottom shell and the bottom plate to rotate alternately, so that the massage wheel on the bottom plate can perform alternating rolling massage on the patient's abdomen, and the alternating rolling can better promote the relaxation of abdominal muscles and blood circulation, help constipation, bloating and other problems, and is closer to the manual alternating rolling massage technique, making the massage process more natural and comfortable. Specifically, in this solution, the number of through grooves is specifically three, and they are evenly spaced at 120° intervals, so that the massage wheels are also spaced 120° apart from each other. The 120° interval makes the massage force evenly applied to the abdomen, avoiding local excessive force or uneven force that may be caused by a single massage wheel, and can better relax the abdominal muscles, improve the comfort of massage, and reduce the discomfort that may be caused by uneven force. When the three equally spaced massage wheels roll, the frequency and rhythm of their contact with the abdomen remain consistent, forming a regular massage rhythm, which helps users relax and adapt to the massage process more easily, just like a professional masseur performing a massage steadily, enhancing the massage effect. Secondly, from the perspective of mechanical structure, the three massage wheels are evenly spaced at 120°, which enables the entire massage device to maintain a good balance during operation, reduces the shaking and noise caused by structural imbalance, ensures a smooth massage process, and also helps to extend the service life of the device. In addition, the abdomen has a certain curvature, and the three massage wheels are evenly spaced to better fit the natural curve of the abdomen, so that the massage wheels are in full contact with the abdominal skin, improve the accuracy and effect of the massage, and ensure that the massage wheels can effectively act on various parts of the abdomen during the massage process. And this distribution method is relatively simple and symmetrical. When users operate the abdominal rolling massage device, it is easier to grasp and adjust the parameters such as the massage position, strength and speed, improve the convenience and flexibility of use, and meet the massage needs of different individuals. The massage wheel is the part that directly contacts the human body for massage, and is usually made of soft, skin-friendly materials such as silicone to ensure the comfort of the massage process. The surface of the massage wheel can be designed with different massage protrusions or textures to enhance the massage effect; secondly, in this solution, the massage wheel rotates and revolves simultaneously during the massage process. The rotation enables the massage wheel to directly roll the abdominal skin and muscles, producing a kneading effect similar to manual massage. The revolution enables the massage wheel to cover a larger area during the massage process, changing the angle and direction of the massage, thereby bringing a richer and more comprehensive massage experience to the user, similar to a professional masseur using a variety of techniques for massage, and through the combination of rotation and revolution, the contact between the massage wheel and the skin is more uniform, avoiding excessive pressure and friction on the skin caused by being fixed in one position for a long time or massaging in a single way.This helps protect your newborn's delicate skin, reduces the risk of skin damage, and makes massage safer and more comfortable.

[0007] Preferably, the transmission device includes a gear and a rack, the gear is fixedly sleeved on the connecting shaft, the rack and the gear are meshed with each other, a limit rod is provided at the bottom of the rack, a limit groove parallel to the rack is provided on the top plate, and the limit rod is slidably embedded in the limit groove; the transmission device also includes a driving assembly, the driving assembly connects the output shaft of the first motor with the rack, and when the output shaft of the first motor rotates, the rack can be driven to reciprocate through the driving assembly. The driving assembly includes a turntable, an eccentric shaft and a transmission rod, the turntable is connected to the output shaft of the first motor, the eccentric shaft is vertically arranged on the turntable and deviates from the center of the turntable, the transmission rod is arranged at one end of the rack and is perpendicular to the rack, and a strip hole is penetrated through the transmission rod, and the eccentric shaft is inserted into the strip hole.

[0008] In this technical solution, it is necessary to explain in detail that the transmission device specifically includes a gear, a rack and a drive assembly. When it is necessary to drive the base plate to perform alternating rotational motion, the first motor is started and the output shaft of the first motor begins to rotate. The rotation of the output shaft drives the turntable and the eccentric shaft on the turntable to perform corresponding rotational motion. The eccentric shaft is arranged on the turntable at a certain eccentric distance, and when the turntable rotates, the eccentric shaft will perform circular motion. This circular motion of the eccentric shaft will produce movement in the bar hole, thereby driving the transmission rod to perform reciprocating linear motion. The rack connected to the transmission rod also performs reciprocating linear motion under the drive of the transmission rod. The movement of the rack will drive the gear meshing with it to perform alternating reciprocating rotational motion clockwise and counterclockwise. This alternating rotational motion of the gear is transmitted through the connecting shaft, thereby driving the outer shell at the bottom of the connecting shaft and the base plate to rotate alternately and reciprocatingly. Ultimately, the massage wheels on the base plate can perform alternating rotating rolling massage on the patient's abdomen, achieving multi-angle, all-round massage effects, better promoting abdominal muscle relaxation and blood circulation, helping to relieve constipation, abdominal bloating and other problems, and are closer to the manual alternating rolling massage technique, making the massage process more natural and comfortable.

[0009] Preferably, an essential oil box is provided on the top of the frame, an opening is provided on the bottom of the essential oil box, a sealing door is slidably embedded in the opening, a liquid outlet is penetrated through the sealing door, a guide rod is provided on the top of the inner cavity of the essential oil box, the bottom of the guide rod passes through the liquid outlet and is connected to a valve for closing the liquid outlet, a first spring is also sleeved on the guide rod, one end of the first spring is connected to the top of the essential oil box, and the other end is connected to the sealing door; the massage wheel is rotatably connected to the frame through a first rotating shaft, a second rotating shaft is also provided on one side of the frame, the second rotating shaft is connected to the first rotating shaft through a conveyor belt, a first cam is provided on the second rotating shaft, and the first cam is in contact with the bottom of the sealing door.

[0010] In this technical solution, it should be noted that the frame and the essential oil box adopt an integrated structural design, and the essential oil box is specially provided with an oil inlet for filling oil, which is convenient for users to add various essential oils, and the frame and the through groove are detachably connected. During operation, when the massage wheel performs rolling massage on the patient, due to the friction between the massage wheel and the patient's skin, a self-rotation motion will be generated. This self-rotation motion is transmitted through the first rotating shaft, thereby driving the conveyor belt connected to the first rotating shaft to rotate. The other end of the conveyor belt is connected to the second rotating shaft, and as the conveyor belt is driven, the second rotating shaft also starts to rotate. A first cam is installed on the second rotating shaft, and the shape and position design of the first cam makes it possible to lift the sealing door upward once every time a circle of rotation is completed during the rotation process. The sealing door is located at the opening of the essential oil box, and a liquid outlet is provided on it, and a valve for closing the liquid outlet is connected to the bottom of the guide rod at the top of the inner cavity of the essential oil box. When the first cam lifts the sealing door, the valve and the liquid outlet are staggered, and the liquid outlet is opened, and the essential oil in the essential oil box can flow out through the liquid outlet and directly act on the patient's skin. At the same time, the rolling massage wheel will evenly apply the flowing essential oil on the skin, which not only enhances the comfort of the massage, but also further enhances the therapeutic effect of the massage through the pharmacological effects of the essential oil, such as promoting blood circulation, relieving muscle tension, etc. In summary, in this scheme, the coordinated cooperation of each device realizes the organic combination of massage and essential oil care, and significantly improves the massage effect and the user's comfort. Specifically, when the massage wheel performs rolling massage on the patient, the friction between the massage wheel and the skin drives the first rotating shaft to rotate, and through the transmission of the conveyor belt, the second rotating shaft rotates accordingly, thereby driving the first cam on it to rotate. The eccentric design of the first cam makes it intermittently lift the sealing door during the rotation process, causing the valve to separate from the liquid outlet, and the essential oil flows out intermittently. The coordination of this series of actions enables the essential oil to act on the skin accurately and timely, and then the rolling massage wheel evenly applies the essential oil to ensure that the skin fully absorbs the essential oil, thereby enhancing the relaxing effect of the massage, promoting blood circulation, and relieving muscle tension. The entire process does not require manual intervention, realizing the automated combination of massage and essential oil care, bringing users a more comfortable and efficient massage experience.

[0011] Preferably, the second rotating shaft is connected to the frame via a one-way bearing, and one end of the conveyor belt is sleeved on the outer ring of the one-way bearing.

[0012] In this technical solution, it should be noted that in this solution, in order to optimize the coordination between the rotation of the massage wheel and the outflow of essential oil, a one-way bearing design is adopted to achieve more precise essential oil control. Specifically, the second rotating shaft is connected to the frame through a one-way bearing, and one end of the conveyor belt is sleeved on the outer ring of the one-way bearing. This design enables the massage wheel to trigger or stop the outflow of essential oil when rotating clockwise and counterclockwise, respectively, thereby avoiding the waste of essential oil and ensuring the rational use of essential oil during massage. When the massage wheel rotates clockwise, the inner and outer rings of the one-way bearing are locked to form a rigid connection. At this time, the rotation of the first rotating shaft drives the second rotating shaft to rotate through the conveyor belt and the one-way bearing. The first cam on the second rotating shaft rotates accordingly, and its eccentric design enables the cam to intermittently lift the sealing door during rotation. The rise of the sealing door causes the valve to separate from the liquid outlet, and the essential oil in the essential oil box can intermittently flow out from the oil outlet and act on the patient's skin. The outflowing essential oil is evenly spread by the rolling massage wheel, which enhances the comfort and therapeutic effect of the massage. However, when the massage wheel rotates counterclockwise, the outer ring of the one-way bearing is in a free state and is no longer locked with the inner ring. At this time, although the first rotating shaft is still rotating, the second rotating shaft will not rotate with it because the outer ring of the one-way bearing can rotate freely. Therefore, the first cam will not rotate, the sealing door will not be lifted, the liquid outlet will remain closed, and no essential oil will flow out. This design effectively avoids the unnecessary outflow of essential oil when the massage wheel rotates counterclockwise, ensures the rational use of essential oil, and avoids waste. Through the ingenious design of this one-way bearing, this scheme realizes the precise coordination of the rotation of the massage wheel and the outflow of essential oil. During the massage process, whenever the massage wheel rotates clockwise, the right amount of essential oil is released, and when it rotates counterclockwise, the release stops, so that the essential oil can be evenly distributed on the skin and give full play to its pharmacological effects, such as promoting blood circulation and relieving muscle tension. This intelligent essential oil control method not only improves the comfort and effect of massage, but also improves the efficiency of essential oil use, bringing users a more efficient and economical massage experience. Furthermore, the length of the cam of this solution is adjustable, and the adjustable length design of the cam provides users with greater flexibility and personalized choices. Specifically, when the user wants to use essential oil to assist massage, the cam can be adjusted to a longer state. At this time, the cam can contact the sealing door during rotation, and intermittently lift the sealing door through its eccentric design, so that the essential oil flows out from the liquid outlet and is evenly applied to the patient's skin, thereby enhancing the massage effect, relieving muscle tension, and promoting blood circulation. On the contrary, when the user does not want to use essential oil, the cam can be adjusted to a shorter mechanism. In this case, even if the cam rotates with the second shaft, its length is not enough to contact the sealing door, so it will not have a lifting effect on the sealing door, the liquid outlet remains closed, and no essential oil will flow out. This design meets the needs of different users and improves the applicability and user experience of the device.The adjustment of the cam length can be achieved through a variety of mechanical structures, such as setting a threaded adjustment device on the cam and changing the extension length of the cam by rotating the adjustment nut; or using a multi-stage cam structure to adjust the effective length of the cam by sliding or disassembling. These adjustment methods are not only easy to operate, but also can accurately control whether the cam is in contact with the sealing door, ensuring the reliability and stability of the device. Through this ingenious cam length adjustment design, the massage device of this solution can flexibly switch between using and not using essential oils, meeting diverse massage needs. It also reflects the humanized design and intelligent control of the device, providing users with a more convenient and efficient massage experience.

[0013] Preferably, a mounting cylinder is provided at the top of the inner cavity of the shell, an electric telescopic rod is provided in the mounting cylinder, a circular plate is provided at the bottom of the electric telescopic rod, a circular hole is provided through the middle of the bottom plate, the circular plate is slidably embedded in the circular hole, and a plurality of massage protrusions are provided at the bottom of the circular plate. A mounting seat is provided at the top of the inner cavity of the mounting cylinder, a second motor is provided on the mounting seat, a second cam that cooperates with the electric telescopic rod is fixedly connected to the output end of the second motor, the electric telescopic rod is slidably connected to the mounting cylinder, and a second spring connected to the mounting cylinder is provided on the electric telescopic rod.

[0014] In this technical solution, it should be noted that, on the basis of the alternating rolling massage, this solution innovatively adds a pressing massage structure, and the two organically cooperate to achieve the diversification of massage methods, significantly improving the massage effect and user comfort. Pressing massage can stimulate blood vessels and acupuncture points in specific parts in a targeted manner, further enhance local blood flow, promote metabolism, and accelerate the body's recovery process. It can directly act on the spasm points and pain points of the muscles, and relieve the tension of the muscles by applying appropriate pressure, thereby reducing muscle soreness and fatigue. In this solution, when it is necessary to perform physical therapy on the patient through pressing massage, the electric telescopic rod is started, and the output end of the electric telescopic rod is extended, driving the circular plate to move downward until the massage protrusion at the bottom of the circular plate moves downward to a position lower than the massage wheel, ensuring that the massage protrusion can accurately contact the patient's skin. After that, the second motor is started, and the output end of the second motor drives the second cam to rotate. During the rotation of the second cam, its protruding part will periodically squeeze the electric telescopic rod downward, so that the electric telescopic rod drives the circular plate and the massage protrusion to move up and down continuously under the elastic action of the second spring. The up and down moving massage protrusions can rhythmically perform a squeezing massage on the patient's abdomen with moderate and even massage force, which can deeply stimulate the abdominal muscles and acupoints, relieve muscle tension, promote gastrointestinal motility, and help digestion. At the same time, it can also stimulate the abdominal acupoints, regulate the body's qi and blood circulation, and achieve better physical therapy effects.

[0015] Preferably, the circular hole is communicated with each of the through slots, the frame is slidably connected to the through slots, one end of the frame is connected to one end of the through slots via a third spring, and a guide surface cooperating with a circular plate is provided on the essential oil box on the top of the frame, the guide surface is inclined, the guide surface is inclined upward in the direction in which the essential oil box is away from the circular plate, and the guide surface is located below the circular plate.

[0016] In this technical solution, it is necessary to explain in detail that a frame for mounting a massage wheel is provided on the bottom plate, so that when the circular plate is set, it is necessary to ensure that the circular plate is staggered with the frame to avoid motion interference between the circular plate and the frame when the circular plate moves downward. However, this staggered arrangement usually limits the area of ​​the circular plate, thereby reducing the number of massage protrusions at the bottom of the circular plate, affecting the massage efficiency. In order to solve this problem, this solution specially designs a guide surface at the top of the essential oil box. The ingenious setting of the guide surface ensures that even if the circular plate is located directly above the guide surface, there will be no motion interference when moving downward. The specific working principle is as follows: when the circular plate moves downward, it will first contact the guide surface at the top of the essential oil box and exert pressure on it. The guide surface adopts a slope design, which can effectively decompose the vertical downward pressure applied by the circular plate into the length direction of the through groove. This decomposition of pressure prompts the essential oil box to move along the through groove in the frame away from the circular plate. As the essential oil box moves, the circular plate and the essential oil box gradually stagger, thereby freeing up more space for the circular plate, enabling it to maintain a larger area, increase the number of massage protrusions, and thus improve the massage efficiency. This design not only cleverly solves the problem of motion interference between the circular plate and the frame, but also improves the massage coverage and effect by optimizing the area of ​​the circular plate and the layout of the massage protrusions. At the same time, the inclined design of the guide surface can also guide the circular plate to slide more smoothly between the frames, ensuring the continuity and stability of the movement during the massage process, bringing users a more comfortable and efficient massage experience. Preferably, a slide groove is provided on the through groove, and a slider is provided on the essential oil box, and the slider is slidably embedded in the slide groove.

[0017] In this technical solution, it should be noted that the provided slider and slide groove are used to limit and guide the essential oil box.

[0018] Preferably, a shell is provided on the top plate, and a handle is provided on the shell.

[0019] In this technical solution, it needs to be further explained that the staff can control the movement of the entire device through the handle to massage different parts of the patient. This design gives the device greater flexibility and convenience, making the treatment process more in line with the patient's personalized needs. Specifically, the setting of the handle enables the operator to flexibly adjust the position of the device according to the patient's specific conditions, such as differences in body parts, the severity of the disease, and the patient's comfort feedback. For example, for patients who need to massage different parts such as the abdomen, back or limbs, the staff can easily move the device to the corresponding position through the handle to achieve accurate treatment. In addition, the device can also be installed on a liftable and movable bracket, further expanding its application range and usage scenarios. The lifting function of this bracket can accurately adjust the height of the device according to the patient's height, body shape and specific treatment area, ensuring that the massage head can accurately act on the target area. At the same time, the mobility of the bracket allows the device to not only be easily transferred between rooms in a hospital or clinic, but also adjust its position in real time as needed during the treatment process to improve treatment efficiency. For example, when treating children or short patients, the device can be lowered to a lower height to better adapt to their body proportions; while for tall patients, the device can be raised to ensure the accuracy and effect of the treatment. Through the dual design of the handle and the liftable mobile bracket, the massage device of this solution is not only easy to operate, but also can better meet the needs of different patients, different diseases and different treatment environments, greatly improving the quality and efficiency of medical care.

[0020] Preferably, it also includes a top shell and a motor, and the top shell is rotatably connected to the top of the shell through rotating parts such as bearings. This connection method allows the top shell to perform stable rotational motion relative to the shell. The motor is firmly mounted on the top with fixings such as bolts, and its output shaft passes through the top shell and is connected to the shell. The handle is on the top shell. By setting the motor, the unidirectional rotation function of the shell can be achieved. Specifically, when a unidirectional rolling massage is required for the patient, the staff can start the motor and select a clockwise or counterclockwise rotation direction according to the patient's specific needs and treatment plan. The output shaft of the motor drives the shell to rotate continuously and stably in the set direction, thereby achieving the effect of a unidirectional rolling massage.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. The physiotherapy device has the function of reciprocating alternating rolling massage, that is, the first motor can drive its own output shaft to rotate, and after the output shaft rotates, the unidirectional rotational motion of the output shaft is converted into the alternating rotational motion of the connecting shaft (that is, clockwise rotation and counterclockwise rotation reciprocating) through the transmission device, thereby driving the bottom shell and the bottom plate to rotate alternately, so that the massage wheel on the bottom plate can perform alternating rolling massage on the patient's abdomen. Alternating rolling can better promote relaxation of abdominal muscles and blood circulation, help constipation, abdominal distension and other problems, and is closer to the manual alternating rolling massage technique, making the massage process more natural and comfortable.

[0022] 2. Diversified massage methods: Combining rolling massage and pressing massage, it can not only promote gastrointestinal motility and blood circulation through the rolling of the massage wheel, but also use the pressing of the massage protrusions to stimulate specific parts, relieve muscle tension and pain, and provide a more comprehensive massage experience.

[0023] 3. Automatic outflow and application of essential oil: Through the unique transmission structure design, the massage wheel can drive the cam to rotate when rolling, intermittently lifting the sealing door to allow the essential oil to flow out, and with the help of the rolling massage wheel, it can be evenly applied to the skin, realizing the automatic combination of massage and essential oil care, enhancing the massage effect, and no human intervention is required.

[0024] 4. One-way bearing optimizes essential oil control: The one-way bearing design allows the essential oil to flow out when the massage wheel rotates clockwise, and stops flowing out when it rotates counterclockwise, accurately controlling the release timing of the essential oil, avoiding waste, and improving the efficiency of essential oil use.

[0025] 5. The cam length is adjustable: The cam length is adjustable, and users can flexibly choose whether to use essential oil massage according to their needs, meeting the personalized needs of different users and improving the applicability and usage experience of the device.

[0026] 6. Spatial layout optimization: By setting a guide surface on the top of the essential oil box, the problem of motion interference between the circular plate and the frame is solved, the circular plate area and the number of massage protrusions are increased, the massage efficiency is improved, and the internal structure of the device is made more compact and reasonable.

[0027] 7. Convenient movement and flexible adjustment: The staff can move the device by controlling the handle to facilitate massaging different parts of the patient. In addition, the device can be installed on a liftable and movable bracket, which further expands the usage scenarios. The height and position can be accurately adjusted according to the patient's height, body shape and treatment part to ensure the accuracy and effectiveness of the treatment.

[0028] 8. The present invention can be adapted to different treatment needs. For example, when the patient needs massage in alternating directions, the massage mode can be switched to the alternating rolling massage mode. When only one-way massage is needed, the massage mode can be switched to the one-way rolling massage mode. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Example 1 like Figure 1-Figure 9As shown, a physiotherapy device is disclosed in an embodiment of the present invention, including a base plate 6, a plurality of through slots 7 are provided at the bottom of the base plate 6, and the plurality of through slots 7 are arranged at equal intervals around the center of the base plate 6, a frame 19 is provided in each of the through slots 7, a massage wheel 20 is rotatably connected in the frame 19, and a side wall of the massage wheel 20 is lower than the bottom of the base plate 6; a shell 5 is arranged around the top of the base plate 6, and the top of the shell 5 is rotatably connected to the top plate 2 through a connecting shaft 4; a first motor and a transmission device are also provided on the top plate 2, and the transmission device transmission-connects the output shaft of the first motor with the connecting shaft 4, and when the output shaft of the first motor rotates, the connecting shaft 4 can be driven to rotate forward and reverse reciprocatingly through the transmission device. It should be noted that the physiotherapy device of the present solution has the function of reciprocating alternating rolling massage, that is, the output shaft of the motor can be driven to rotate by the first motor, and after the output shaft rotates, the unidirectional rotational motion of the output shaft is converted into the alternating rotational motion of the connecting shaft 4 (i.e., clockwise rotation and counterclockwise rotation are performed reciprocatingly) through the transmission device, thereby driving the bottom shell 5 and the bottom plate 6 to rotate alternately, so that the massage wheel 20 on the bottom plate 6 can perform alternating rolling massage on the patient's abdomen, and the alternating rolling can better promote the relaxation of the abdominal muscles and blood circulation, help constipation, abdominal distension and other problems, and is closer to the manual alternating rolling massage technique, making the massage process more natural and comfortable. Specifically, in the present solution, the number of through grooves 7 is specifically three, and they are evenly spaced at 120°. In this way, the massage wheels 20 are also spaced at 120° from each other. The 120° distribution makes the massage force evenly applied to the abdomen, avoiding the local excessive force or uneven force that may be caused by a single massage wheel 20, and can better relax the abdominal muscles, improve the massage comfort, and reduce the discomfort caused by uneven force. When the three massage wheels 20 are evenly distributed, their frequency and rhythm of contacting the abdomen are consistent when rolling, forming a regular massage rhythm, which helps the user relax and adapt to the massage process more easily, just like a professional masseur performing massage steadily, enhancing the massage effect. Secondly, from the perspective of mechanical structure, the three massage wheels 20 are evenly distributed at 120°, so that the entire massage device maintains a good balance during operation, reduces the shaking and noise caused by structural imbalance, ensures a smooth massage process, and is also conducive to extending the service life of the device. In addition, the abdomen has a certain curvature, and the three massage wheels 20 are evenly distributed, which can better fit the natural curve of the abdomen, so that the massage wheels 20 are fully in contact with the abdominal skin, improve the accuracy and effect of the massage, and ensure that the massage wheels 20 can effectively act on various parts of the abdomen during the massage process. And this distribution method is relatively simple and symmetrical. When the user operates the abdominal rolling massage device, it is easier to grasp and adjust the parameters such as the massage position, strength and speed, improve the convenience and flexibility of use, and meet the massage needs of different individuals.The massage wheel 20 is the part that directly contacts the human body for massage, and is usually made of soft, skin-friendly materials, such as silicone, to ensure the comfort of the massage process. The surface of the massage wheel 20 can be designed with different massage protrusions 18 or textures to enhance the massage effect; secondly, in this solution, the massage wheel 20 rotates and revolves simultaneously during the massage process, and the rotation enables the massage wheel 20 to perform a direct rolling massage on the abdominal skin and muscles, producing a kneading effect similar to manual massage. The revolution enables the massage wheel 20 to cover a larger area during the massage process, change the angle and direction of the massage, thereby bringing a richer and more comprehensive massage experience to the user, similar to a professional masseur using a variety of techniques for massage, and through the combination of rotation and revolution, the contact between the massage wheel 20 and the skin is more uniform, avoiding excessive pressure and friction on the skin caused by being fixed in one position for a long time or massaging in a single way. This helps to protect the delicate skin of newborns, reduce the risk of skin damage, and improve the safety and comfort of massage.

[0038] like Figure 3As shown, in this embodiment, the transmission device includes a gear 10 and a rack 9, the gear 10 is fixedly sleeved on the connecting shaft 4, the rack 9 and the gear 10 are meshed with each other, a limit rod 11 is provided at the bottom of the rack 9, and a limit groove 12 parallel to the rack 9 is provided on the top plate 2, and the limit rod 11 is slidably embedded in the limit groove 12; the transmission device also includes a driving assembly, the driving assembly drives the output shaft of the first motor to connect with the rack 9, when the output shaft of the first motor rotates, the rack 9 can be driven to move back and forth through the driving assembly. The driving assembly includes a turntable 8, an eccentric shaft 15 and a transmission rod 14, the turntable 8 is connected to the output shaft of the first motor, the eccentric shaft 15 is vertically arranged on the turntable 8 and deviates from the center of the turntable 8, the transmission rod 14 is arranged at one end of the rack 9 and is perpendicular to the rack 9, and a strip hole 13 is penetrated through the transmission rod 14, and the eccentric shaft 15 is inserted into the strip hole 13. It should be explained in detail that the transmission device specifically includes a gear 10, a rack 9 and a driving assembly. When the base plate 6 needs to be driven to perform alternating rotational motion, the first motor is started and the output shaft of the first motor begins to rotate. The rotation of the output shaft drives the turntable 8 and the eccentric shaft 15 on the turntable 8 to perform corresponding rotational motion. The eccentric shaft 15 is arranged on the turntable 8 at a certain eccentric distance. When the turntable 8 rotates, the eccentric shaft 15 will perform circular motion. This circular motion of the eccentric shaft 15 will produce movement in the bar hole 13, thereby driving the transmission rod 14 to perform reciprocating linear motion. The rack 9 connected to the transmission rod 14 also performs reciprocating linear motion under the drive of the transmission rod 14. The movement of the rack 9 will drive the gear 10 meshing therewith to perform alternating reciprocating rotational motion in a clockwise and counterclockwise direction. This alternating rotational motion of the gear 10 is transmitted through the connecting shaft 4, thereby driving the housing 5 and the base plate 6 at the bottom of the connecting shaft 4 to rotate alternately and reciprocatingly. Finally, the massage wheel 20 on the base plate 6 can perform alternating rotating rolling massage on the patient's abdomen, achieving a multi-angle, all-round massage effect, better promoting relaxation of the abdominal muscles and blood circulation, helping to relieve constipation, abdominal bloating and other problems, and is closer to the manual alternating rolling massage technique, making the massage process more natural and comfortable.

[0039] like Figure 6 , Figure 8 and Fig. 9As shown, in this embodiment, an essential oil box 21 is provided at the top of the frame 19, and an opening is provided at the bottom of the essential oil box 21. A sealing door 36 is slidably embedded at the opening, and a liquid outlet is penetrated through the sealing door 36. A guide rod 38 is provided at the top of the inner cavity of the essential oil box 21, and the bottom of the guide rod 38 passes through the liquid outlet and is connected to a valve 37 for closing the liquid outlet. A first spring 39 is also sleeved on the guide rod 38, one end of the first spring 39 is connected to the top of the essential oil box 21, and the other end is connected to the sealing door 36; the massage wheel 20 is rotatably connected to the frame 19 through a first rotating shaft 30, and a second rotating shaft 31 is also provided on one side of the frame 19, and the second rotating shaft 31 is connected to the first rotating shaft 30 through a conveyor belt 34, and a first cam 32 is provided on the second rotating shaft 31, and the first cam 32 contacts the bottom of the sealing door 36. It should be noted that the frame 19 and the essential oil box 21 adopt an integrated structural design. The essential oil box 21 is specially provided with an oil inlet for filling oil, which is convenient for users to add various essential oils. The frame 19 and the through groove 7 are detachably connected. During operation, when the massage wheel 20 performs rolling massage on the patient, due to the friction between the massage wheel 20 and the patient's skin, a self-rotation motion will be generated. This self-rotation motion is transmitted through the first rotating shaft 30, thereby driving the conveyor belt 34 connected to the first rotating shaft 30 to rotate. The other end of the conveyor belt 34 is connected to the second rotating shaft 31. With the transmission of the conveyor belt 34, the second rotating shaft 31 also starts to rotate. A first cam 32 is installed on the second rotating shaft 31. The shape and position design of the first cam 32 makes it possible to push up the sealing door 36 once every time a circle of rotation is completed during the rotation process. The sealing door 36 is located at the opening of the essential oil box 21, and a liquid outlet is provided on it, and a valve 37 for closing the liquid outlet is connected to the bottom of the guide rod 38 at the top of the inner cavity of the essential oil box 21. When the first cam 32 lifts the sealing door 36, the valve 37 is staggered with the liquid outlet, and the liquid outlet is opened, and the essential oil in the essential oil box 21 can flow out through the liquid outlet and directly act on the patient's skin. At the same time, the rolling massage wheel 20 will evenly apply the outflowing essential oil on the skin, which not only enhances the comfort of the massage, but also further enhances the therapeutic effect of the massage through the pharmacological effects of the essential oil, such as promoting blood circulation, relieving muscle tension, etc. In summary, in this solution, the coordinated cooperation of each device realizes the organic combination of massage and essential oil care, significantly improving the massage effect and the user's comfort. Specifically, when the massage wheel 20 performs rolling massage on the patient, the friction between it and the skin drives the first rotating shaft 30 to rotate, and through the transmission of the conveyor belt 34, the second rotating shaft 31 rotates accordingly, thereby driving the first cam 32 thereon to rotate. The eccentric design of the first cam 32 makes it intermittently lift the sealing door 36 during the rotation process, causing the valve 37 to separate from the liquid outlet, and the essential oil flows out intermittently.The coordination of this series of actions enables the essential oil to act on the skin accurately and timely, and then the rolling massage wheel 20 evenly applies the essential oil to ensure that the skin fully absorbs the essential oil, thereby enhancing the relaxing effect of the massage, promoting blood circulation, and relieving muscle tension. The entire process does not require manual intervention, realizing the automated combination of massage and essential oil care, bringing users a more comfortable and efficient massage experience.

[0040] like Figure 8As shown, in this embodiment, the second rotating shaft 31 is connected to the frame 19 through a one-way bearing 33, and one end of the conveyor belt 34 is sleeved on the outer ring of the one-way bearing 33. It should be noted that in this solution, in order to optimize the coordination between the rotation of the massage wheel 20 and the outflow of essential oil, the design of the one-way bearing 33 is adopted to achieve more precise control of the essential oil. Specifically, the second rotating shaft 31 is connected to the frame 19 through the one-way bearing 33, and one end of the conveyor belt 34 is sleeved on the outer ring of the one-way bearing 33. This design enables the massage wheel 20 to trigger or stop the outflow of essential oil when rotating clockwise and counterclockwise, thereby avoiding the waste of essential oil and ensuring the reasonable use of essential oil during massage. When the massage wheel 20 rotates clockwise, the inner ring and outer ring of the one-way bearing 33 are locked to form a rigid connection. At this time, the rotation of the first rotating shaft 30 drives the second rotating shaft 31 to rotate through the conveyor belt 34 and the one-way bearing 33. The first cam 32 on the second rotating shaft 31 rotates accordingly, and its eccentric design enables the cam to intermittently lift the sealing door 36 during the rotation process. The rise of the sealing door 36 causes the valve 37 to separate from the liquid outlet, and the essential oil in the essential oil box 21 can intermittently flow out from the oil outlet 40 to act on the patient's skin. The essential oil that flows out is evenly applied by the rolling massage wheel 20, which enhances the comfort and therapeutic effect of the massage. However, when the massage wheel 20 rotates counterclockwise, the outer ring of the one-way bearing 33 is in a free state and is no longer locked with the inner ring. At this time, although the first rotating shaft 30 is still rotating, the second rotating shaft 31 will not rotate accordingly because the outer ring of the one-way bearing 33 can rotate freely. Therefore, the first cam 32 will not rotate either, will not lift the sealing door 36, the liquid outlet remains closed, and no essential oil will flow out. This design effectively avoids unnecessary outflow of essential oil when the massage wheel 20 rotates counterclockwise, ensures the rational use of essential oil, and avoids waste. Through the ingenious design of this one-way bearing 33, this solution achieves the precise coordination between the rotation of the massage wheel 20 and the outflow of essential oil. During the massage process, whenever the massage wheel 20 rotates clockwise, the right amount of essential oil is released, and when it rotates counterclockwise, the release is stopped, so that the essential oil can be evenly distributed on the skin, giving full play to its pharmacological effects, such as promoting blood circulation, relieving muscle tension, etc. This intelligent essential oil control method not only improves the comfort and effect of massage, but also improves the efficiency of the use of essential oil, bringing users a more efficient and economical massage experience. Further, the length of the cam of this solution is adjustable, and the adjustable length design of the cam provides users with greater flexibility and personalized choices. Specifically, when the user wants to use essential oil to assist massage, the cam can be adjusted to a longer state. At this time, the cam can contact the sealing door 36 during the rotation process, and intermittently lift the sealing door 36 through its eccentric design, so that the essential oil flows out from the liquid outlet and is evenly applied to the patient's skin, thereby enhancing the massage effect, relieving muscle tension, and promoting blood circulation.On the contrary, when the user does not want to use essential oil, the cam can be adjusted to a shorter mechanism. In this case, even if the cam rotates with the second rotating shaft 31, its length is not enough to contact the sealing door 36, so it will not have a lifting effect on the sealing door 36, the liquid outlet remains closed, and no essential oil will flow out. This design meets the needs of different users and improves the applicability and user experience of the device. The adjustment of the cam length can be achieved through a variety of mechanical structures, such as setting a threaded adjustment device on the cam to change the extension length of the cam by rotating the adjustment nut; or using a multi-stage cam structure to adjust the effective length of the cam by sliding or disassembling. These adjustment methods are not only easy to operate, but also can accurately control whether the cam is in contact with the sealing door 36, ensuring the reliability and stability of the device. Through this ingenious cam length adjustment design, the massage device of this scheme can flexibly switch between using and not using essential oils, meeting diverse massage needs, and also embodies the humanized design and intelligent control of the device, providing users with a more convenient and efficient massage experience.

[0041] like Figure 6 and Figure 7As shown, in this embodiment, a mounting cylinder 17 is provided at the top of the inner cavity of the housing 5, and an electric telescopic rod 28 is provided in the mounting cylinder 17. A circular plate 16 is provided at the bottom of the electric telescopic rod 28. A circular hole is provided through the middle of the bottom plate 6, and the circular plate 16 is slidably embedded in the circular hole. A plurality of massage protrusions 18 are provided at the bottom of the circular plate 16. A mounting seat 25 is provided at the top of the inner cavity of the mounting cylinder 17, and a second motor 26 is provided on the mounting seat 25. A second cam 27 that cooperates with the electric telescopic rod 28 is fixedly connected to the output end of the second motor 26. The electric telescopic rod 28 is slidably connected to the mounting cylinder 17, and a second spring 29 connected to the mounting cylinder 17 is provided on the electric telescopic rod 28. It should be noted that, on the basis of the alternating rolling massage, this solution innovatively adds a pressing massage structure, and the organic combination of the two realizes the diversification of massage methods, and significantly improves the massage effect and user comfort. The pressing massage can stimulate the blood vessels and acupuncture points of specific parts in a targeted manner, further enhance local blood flow, promote metabolism, and accelerate the body's recovery process. It can directly act on the spasm points and pain points of the muscles, and relieve the tension of the muscles by applying appropriate pressure, thereby reducing muscle soreness and fatigue. In this solution, when the patient needs to be treated with a pressing massage, the electric telescopic rod 28 is started, and the output end of the electric telescopic rod 28 is extended, driving the circular plate 16 to move downward until the massage protrusion 18 at the bottom of the circular plate 16 moves downward to a position lower than the massage wheel 20, ensuring that the massage protrusion 18 can accurately contact the patient's skin. After that, the second motor 26 is started, and the output end of the second motor 26 drives the second cam 27 to rotate. During the rotation of the second cam 27, its protruding part will periodically squeeze the electric telescopic rod 28 downward, so that the electric telescopic rod 28 drives the circular plate 16 and the massage protrusion 18 to move up and down continuously under the elastic action of the second spring 29. The up and down moving massage protrusions 18 can rhythmically perform squeezing massage on the patient's abdomen with moderate and even massage force, which can deeply stimulate the abdominal muscles and acupoints, relieve muscle tension, promote gastrointestinal motility, and help digestion. At the same time, it can also stimulate the abdominal acupoints, regulate the body's qi and blood circulation, and achieve better physical therapy effects.

[0042] An electric telescopic rod 28 is provided in the mounting tube 17, and a circular plate 16 is provided at the bottom of the electric telescopic rod 28. A circular hole is provided in the middle of the bottom plate 6, and the circular plate 16 is slidably embedded in the circular hole. A plurality of massage protrusions 18 are provided at the bottom of the circular plate 16. A mounting seat 25 is provided at the top of the inner cavity of the mounting tube 17, and a second motor 26 is provided on the mounting seat 25. A second cam 27 that cooperates with the electric telescopic rod 28 is fixedly connected to the output end of the second motor 26. The electric telescopic rod 28 is slidably connected to the mounting tube 17, and a second spring 29 connected to the mounting tube 17 is provided on the electric telescopic rod 28. It should be noted that, on the basis of the alternating rolling massage, this scheme innovatively adds a pressing massage structure, and the two are organically matched to achieve the diversification of massage methods, and significantly improve the massage effect and user comfort. Pressing massage can stimulate blood vessels and acupuncture points in specific parts in a targeted manner, further enhance local blood flow, promote metabolism, and accelerate the body's recovery process. It can directly act on the spasm points and pain points of the muscles, and relieve the tension of the muscles by applying appropriate pressure, thereby reducing muscle soreness and fatigue. In this solution, when the patient needs to be treated with a press-type massage, the electric telescopic rod 28 is started, and the output end of the electric telescopic rod 28 is extended, driving the circular plate 16 to move downward until the massage protrusion 18 at the bottom of the circular plate 16 moves downward to a position lower than the massage wheel 20, ensuring that the massage protrusion 18 can accurately contact the patient's skin. After that, the second motor 26 is started, and the output end of the second motor 26 drives the second cam 27 to rotate. During the rotation of the second cam 27, its protruding part will periodically squeeze the electric telescopic rod 28 downward, so that the electric telescopic rod 28 drives the circular plate 16 and the massage protrusion 18 to move up and down continuously under the elastic action of the second spring 29. The massage protrusion 18 that moves up and down can rhythmically perform squeezing massage on the patient's abdomen, and the massage force is moderate and uniform, which can deeply stimulate the abdominal muscles and acupuncture points, relieve muscle tension, promote gastrointestinal peristalsis, help digestion, and stimulate the acupuncture points in the abdomen, regulate the body's blood circulation, and achieve better physical therapy effects. The straight downward pressure is effectively decomposed to the length direction of the through groove 7. The decomposition of this pressure prompts the essential oil box 21 to move along the through groove 7 in the frame 19 in the direction away from the circular plate 16. As the essential oil box 21 moves, the circular plate 16 and the essential oil box 21 are gradually staggered, thereby freeing up more space for the circular plate 16, enabling it to maintain a larger area, increasing the number of massage protrusions 18, and thus improving the massage efficiency. This design not only cleverly solves the problem of motion interference between the circular plate 16 and the frame 19, but also improves the coverage and effect of massage by optimizing the area of ​​the circular plate 16 and the layout of the massage protrusions 18.At the same time, the inclined design of the guide surface 22 can also guide the circular plate 16 to slide more smoothly between the frames 19, ensuring the continuity and stability of the movements during the massage process, and bringing a more comfortable and efficient massage experience to the user. like Figure 6 As shown, in this embodiment, the through groove 7 is provided with a slide groove 24, and the essential oil box 21 is provided with a slider, and the slider is slidably embedded in the slide groove 24. It should be noted that the slider and the slide groove 24 are used to limit and guide the essential oil box 21.

[0043] like Figure 1 As shown, in this embodiment, a shell 1 is provided on the top plate 2, and a handle 3 is provided on the shell 1. It should be further explained that the staff can control the movement of the entire device through the handle 3, so as to massage different positions of the patient. This design gives the device greater flexibility and convenience, making the treatment process more in line with the patient's personalized needs. Specifically, the setting of the handle 3 enables the operator to flexibly adjust the position of the device according to the specific conditions of the patient, such as differences in body parts, the severity of the disease, and the patient's comfort feedback. For example, for patients who need to massage different parts such as the abdomen, back or limbs, the staff can easily move the device to the corresponding position through the handle 3 to achieve accurate treatment. In addition, the device can also be installed on a liftable and movable bracket, further expanding its application range and usage scenarios. The lifting function of this bracket can accurately adjust the height of the device according to the patient's height, body shape and specific treatment part, ensuring that the massage head can accurately act on the target area. At the same time, the mobility of the bracket allows the device to not only be easily transferred between rooms in a hospital or clinic, but also adjust its position in real time as needed during the treatment process, thereby improving the treatment efficiency. For example, when treating children or patients with short stature, the device can be lowered to a lower height to better adapt to their body proportions; while for tall patients, the device can be raised to ensure the accuracy and effect of the treatment. Through the dual design of the handle 3 and the liftable movable bracket, the massage device of this solution is not only easy to operate, but also can better meet the needs of different patients, different diseases and different treatment environments, greatly improving the quality and efficiency of medical care.

[0044] The working principle of this embodiment is: Device startup and initial adjustment: The staff moves the device to the position where the patient needs to be massaged by means of the handle 3, and adjusts the position and height of the device according to the patient's specific conditions, such as body parts, body shape and condition. If the device is installed on a liftable and movable bracket, the height of the device is accurately adjusted using the lifting function of the bracket to ensure that the massage wheel 20 and the massage protrusion 18 can accurately act on the target area.

[0045] Alternating rolling massage: The first motor is started, and its output shaft rotates and drives the connecting shaft 4 to rotate forward and backward through the transmission device. Specifically, the output shaft of the first motor rotates to drive the turntable 8 and the eccentric shaft 15 to rotate, and the circular motion of the eccentric shaft 15 is transmitted to the transmission rod 14 through the bar hole 13, so that it performs reciprocating linear motion. The transmission rod 14 drives the rack 9 to perform reciprocating linear motion, and the rack 9 meshes with the gear 10, so that the gear 10 performs alternating reciprocating rotation clockwise and counterclockwise. The rotation of the gear 10 is transmitted through the connecting shaft 4, driving the bottom shell 5 and the bottom plate 6 to rotate alternately, so that the massage wheel 20 on the bottom plate 6 performs alternating rolling massage on the patient's abdomen.

[0046] Rolling massage and essential oil application: During the rolling massage process, the massage wheel 20 generates a self-rotating motion due to the friction with the patient's skin. The self-rotating massage wheel 20 drives the conveyor belt 34 to rotate through the first rotating shaft 30, thereby rotating the second rotating shaft 31. During the rotation process, the first cam 32 on the second rotating shaft 31 will push up the sealing door 36 once every time it completes a circle of rotation. The sealing door 36 rises to stagger the valve 37 and the liquid outlet, the liquid outlet opens, and the essential oil in the essential oil box 21 flows out and acts on the patient's skin. The rolling massage wheel 20 evenly applies the flowing essential oil on the skin, realizing the organic combination of massage and essential oil care.

[0047] One-way bearing 33 with essential oil control: The second rotating shaft 31 is connected to the frame 19 through the one-way bearing 33, and one end of the conveyor belt 34 is sleeved on the outer ring of the one-way bearing 33. When the massage wheel 20 rotates clockwise, the inner and outer rings of the one-way bearing 33 are locked to form a rigid connection. The first rotating shaft 30 drives the second rotating shaft 31 to rotate through the conveyor belt 34 and the one-way bearing 33, and then drives the first cam 32 to rotate, so that the essential oil flows out. When the massage wheel 20 rotates counterclockwise, the outer ring of the one-way bearing 33 is in a free state, the second rotating shaft 31 does not rotate, the first cam 32 does not rotate, the sealing door 36 will not be lifted, the liquid outlet remains closed, and no essential oil flows out. This design achieves precise coordination between the rotation of the massage wheel 20 and the outflow of essential oil.

[0048] Pressure massage: The electric telescopic rod 28 is started, and its output end extends to drive the circular plate 16 to move downward until the massage protrusion 18 at the bottom of the circular plate 16 moves downward to a position lower than the massage wheel 20, ensuring that the massage protrusion 18 can accurately contact the patient's skin. Then the second motor 26 is started, and the output end of the second motor 26 drives the second cam 27 to rotate. During the rotation of the second cam 27, its protrusion will periodically squeeze the electric telescopic rod 28 downward, so that the electric telescopic rod 28 drives the circular plate 16 and the massage protrusion 18 to move up and down continuously under the elastic action of the second spring 29, and performs a squeezing massage on the patient's abdomen.

[0049] Spatial layout optimization and motion interference resolution: A frame 19 for mounting a massage wheel 20 is provided on the bottom plate 6, and a circular hole is connected to each through slot 7, and the frame 19 is slidably connected to the through slot 7, and one end of the frame 19 is connected to one end of the through slot 7 through a third spring 23. A guide surface 22 cooperating with the circular plate 16 is provided on the top of the frame 19. The guide surface 22 is inclined. When the circular plate 16 moves downward, it will contact the guide surface 22 on the top of the essential oil box 21 and exert pressure on it. The guide surface 22 decomposes the vertical downward pressure into the length direction of the through slot 7, prompting the essential oil box 21 to move in the frame 19 along the through slot 7 in the direction away from the circular plate 16, so that the circular plate 16 and the essential oil box 21 are gradually staggered to avoid motion interference. This not only increases the area of ​​the circular plate 16, increases the number of massage protrusions 18, and improves the massage efficiency, but also ensures the continuity and stability of the movements during the massage process.

[0050] Example 2 like Fig.10 As shown, this embodiment is provided with a top shell 41 and a motor 42 on the basis of the embodiment 1, and the top shell 41 is rotatably connected with the top of the housing 1 through a rotating part such as a bearing, and this connection mode enables the top shell 41 to perform a stable rotational motion relative to the housing 1. The motor 42 is firmly mounted on the top shell 41 by means of fixing parts such as bolts, and its output shaft passes through the top shell 41 and is connected to the housing 1.

[0051] In Example 2, the handle is provided on the top shell 41. By providing the motor 42, the one-way rotation function of the shell 1 can be realized. Specifically, when a one-way rolling massage is required for the patient, the staff can start the motor 42 and select the clockwise or counterclockwise rotation direction according to the patient's specific needs and treatment plan. The output shaft of the motor 42 drives the shell 1 to rotate continuously and stably in the set direction, thereby achieving the effect of one-way rolling massage.

[0052] The flexibility of this design lies in that it can be adaptively selected according to different treatment needs. For example, when the patient needs massage in alternating directions to promote blood circulation and relieve muscle tension, the device of embodiment 1 can be switched to perform alternating rolling massage. When only one-way massage is required, the motor drive of embodiment 2 can provide a more stable and continuous massage effect to meet diverse treatment needs.
