Description

Technical Field

[0001] The present invention relates to the technical field of acupuncture and massage, and in particular to a portable acupuncture and massage device. Background Art

[0002] Acupuncture and massage, as traditional Chinese medicine treatments, works by stimulating acupuncture points and meridians to promote blood circulation and regulate organ function, thereby unblocking Qi and blood circulation, relieving fatigue, and aiding in fat loss. For obese individuals, the abdomen is a primary area of ​​fat accumulation. Targeted acupuncture and massage can effectively boost abdominal metabolism, help break down fat, and reduce abdominal bloating.

[0003] An example of a portable acupuncture and massage device in the prior art is the Kangshubao HA-01. This handheld device is compact, lightweight, and easy to carry. It integrates both massage and acupressure functions. The massage function relies on an internal micro-motor to drive the massage heads, generating vibrations that relax and massage muscles. The massage function is also available in a variety of shapes, allowing for targeted massage of various body parts, such as the shoulders, waist, abdomen, and legs.

[0004] However, in actual use, the portable acupuncture and massage device exhibits significant limitations when used with obese individuals. Due to the thick abdominal fat and low nerve sensitivity of obese individuals, the device struggles to automatically adjust massage intensity based on the varying fat thicknesses in different abdominal regions. It can only provide a fixed massage pattern and intensity, making it difficult to adapt the massage intensity to the various abdominal regions of an obese individual. Therefore, it is necessary to propose a portable acupuncture and massage device to address the difficulty of existing portable acupuncture and massage devices in adapting massage intensity to the varying fat thicknesses of obese individuals. Summary of the Invention

[0005] To solve the above problems, the present invention provides a portable acupuncture and massage device, which is used to adaptively adjust the massage intensity of different abdominal areas according to the uneven thickness of abdominal fat in obese users, while improving the fit with the abdomen when worn, thereby providing obese users with effective abdominal acupuncture and massage services.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a portable acupuncture and massage device comprising a massager body, the massager body being provided with a plurality of massage heads, each of which has one end extending through a side wall of the massager body and slidingly engaging with the side wall; elastic bands being symmetrically provided on the side wall of the massager body, and an adjustment assembly for adjusting the tightness of the elastic bands when worn, provided between adjacent ends of the elastic bands facing away from the massager body. Each massage head is provided with a vibration assembly for driving the vibration of the massage head, and an adaptive adjustment assembly for adjusting the vibration intensity of the massage head according to the fat thickness at different locations on the user's abdomen. Each massage head is also provided with a drive assembly for driving the vibration assembly; a fitting assembly is provided on the massager body for automatically fitting the elastic bands to the user's abdomen when adjusting the tightness of the elastic bands; and each massage head is also provided with an acupuncture assembly for performing acupuncture on the user while the massage head vibrates and massages the user.

[0007] The technical principles of the above scheme are as follows: The user stretches the elastic strap to wear the device on the abdomen, then adjusts the tightness of the elastic strap using the adjustment component. The fitting component then adapts to the changing contours of the abdomen, filling the gap between the device and the abdomen caused by fat accumulation. The drive component provides power to the vibration component, enabling it to drive the massage heads to vibrate and provide a vibration massage on the user's abdomen. As different massage heads contact different areas of the abdomen, the adaptive adjustment components on these massage heads adjust the vibration intensity of the vibration components in that area based on the varying fat thickness.

[0008] The above scheme has the following beneficial effects: 1. The present invention provides an adaptive adjustment component that can automatically adjust the vibration intensity of the massage head in the corresponding area according to the fat thickness differences in different areas of the abdomen of obese users. This breaks the limitations of the fixed intensity mode of existing devices and allows each area to obtain an adaptive massage intensity, thereby more accurately stimulating the abdominal acupuncture points and meridians, enhancing the effect of promoting blood circulation and regulating the functions of internal organs, and improving the efficiency of assisting fat loss.

[0009] 2. The elastic strap, adjustment component and fitting component of the present invention cooperate to adjust the tightness through the adjustment component when worn, and the fitting component can automatically adapt to the abdominal contour to fill the gap caused by fat accumulation, thereby greatly improving the fit between the device and the abdomen.

[0010] 3. The overall structure of the present invention is compact. It integrates various functional components on the massager body and is portable with elastic straps, making it convenient for users to carry and use at any time. It meets the needs of obese users for abdominal acupuncture and massage in various scenarios such as at home and in the office.

[0011] Furthermore, the adjustment component includes a controller and an adjustment box, a first driving member is fixedly connected to the inner wall of the adjustment box, and the controller is used to control the rotation of the output shaft of the first driving member; a gear is coaxially fixedly connected to the output shaft of the first driving member, and a rack is symmetrically and meshed on the gear, and the racks slide with the bottom wall and the top wall of the adjustment box respectively, and one end of the racks passes through the adjacent side wall of the adjustment box and is fixedly connected to a fixing ring, and the fixing rings are fixedly connected to the adjacent elastic straps.

[0012] Beneficial effect: The controller controls the first driving member to drive the gear to rotate, and the meshing transmission of the gear and the rack can make the racks on both sides slide synchronously in opposite directions, and then drive the elastic strap to automatically retract and extend through the fixed ring. The elastic strap can be quickly retracted and extended, making it easy for users to wear it quickly.

[0013] Furthermore, the massage heads are slidably fitted with the massager body; the vibration assembly includes a slide groove opened on the inner side wall of the massager body, a support block is slidably fitted in the slide groove, the support block is fixedly connected to the bottom of the massage head, a first connecting rod is hinged on the side wall of the support block, a second connecting rod is hinged on the side wall of the first connecting rod, and the second connecting rod is symmetrical away from one end of the first connecting rod and is hinged to a third connecting rod.

[0014] Beneficial effect: The driving component drives the third connecting rod to rotate, and cooperates with the hinge structure of the first connecting rod, the second connecting rod and the third connecting rod to convert power into reciprocating sliding of the massage head during the transmission process, causing the massage head to vibrate reciprocatingly, simulating the pressing and relaxation during manual massage.

[0015] Furthermore, the adaptive adjustment component includes a sliding rod hinged to the end of the first connecting rod away from the support block. The end of the sliding rod away from the first connecting rod passes through the top wall of the massager body and slides with the top wall of the massager body. The end of the sliding rod away from the first connecting rod is fixedly connected to a buffer block.

[0016] Beneficial effect: When the massage head contacts areas of different fat thickness on the abdomen, the buffer block will first contact the abdomen. The area with thicker fat will produce greater pressure on the buffer block, pushing the slide rod to slide different distances, and then the support block and the massage head are driven to adjust their positions through the first connecting rod, so that the reciprocating motion stroke of the massage head changes, thereby realizing the function of adjusting the vibration intensity of the massage head.

[0017] Furthermore, the drive assembly includes a second drive member and a first rotating shaft. The second drive member is fixedly connected to the inner bottom wall of the massager body, and a controller is used to control the rotation of the second drive member's output shaft. The second drive member's output shaft is fixedly connected to an adjacent third connecting rod, and a first pulley is coaxially fixedly connected to the second drive member's output shaft. One end of the first rotating shaft is rotationally engaged with the inner side wall of the massager body, and the other end of the first rotating shaft is fixedly connected to the adjacent third connecting rod. A second pulley is coaxially fixedly connected to the first rotating shaft, and a belt is tensioned between the first and second pulleys. The second rotating shaft is fixedly connected between adjacent third connecting rods. Third rotating shafts are symmetrically and rotationally engaged on the inner side wall of the massager body, and the ends of the third rotating shafts facing away from the inner side wall of the massager body are fixedly connected to the adjacent third connecting rods.

[0018] Beneficial effects: The second driving member drives the first rotating shaft to rotate synchronously through belt transmission, and cooperates with the connection between the second rotating shaft and the third rotating shaft to enable multiple third connecting rods to rotate, ensuring that all vibration components can operate synchronously and ensuring the coordination of vibration of each massage head. At the same time, the belt transmission has a buffering and shock-absorbing effect, which can extend the service life of the device.

[0019] Furthermore, the fitting assembly includes an annular airbag fixedly connected to the side wall of the massager body, and a wheel coaxially fixedly connected to the side wall of the gear away from the first drive member; a crank is eccentrically hinged on the wheel, a piston rod is hinged on the end of the crank away from the wheel, a piston block is fixedly connected to the end of the piston rod away from the crank, a first piston cylinder is slidably engaged with the outside of the piston block, the first piston cylinder is fixedly connected to the inner bottom wall of the regulating box, an air inlet pipe and an air outlet pipe are connected to the side wall of the first piston cylinder, a one-way valve is connected to the air inlet pipe and the air outlet pipe, the air inlet pipe is connected to the outside of the regulating box, the air outlet pipe is connected to the annular airbag, and the annular airbag is connected to an air release nozzle. The massage head is equipped with a finger pressure assembly for simulating manual finger pressure during massage.

[0020] Beneficial effects: When the gear rotates, the wheel drives the synchronous rotation. Through the cooperation of the crank, piston rod and piston block, the first piston cylinder inflates the annular airbag. The annular airbag expands synchronously to adapt to the changes in the abdominal contour, further fill the gap, and increase the stability of the device fixation. The flexible contact of the airbag can reduce the pressure on the abdominal skin.

[0021] Furthermore, the acupressure assembly includes a push-pull rod fixedly connected to the bottom of the support block, and the massage head is fixedly connected to an inflatable ball at one end away from the support block; a second piston cylinder is provided below the push-pull rod, and the bottom end of the push-pull rod passes through the top wall of the second piston cylinder and extends into the second piston cylinder and is fixedly connected to a push block, and the push block and the inner side wall of the second piston cylinder slide together; an air pipe is connected to the top of the second piston cylinder, and an exhaust hole is opened at the bottom of the second piston cylinder. The air pipe is connected to the inflatable ball at one end away from the second piston cylinder, and the material of the inflatable ball is silicone.

[0022] Beneficial effects: When the support block slides up and down, it drives the push-pull rod and the piston to reciprocate in the second piston cylinder, and the inflatable ball is inflated and deflated through the trachea, causing the inflatable ball to expand and contract, simulating the pressing effect of manual acupressure. Combined with vibration massage, it enriches the massage methods, enhances the stimulation intensity of acupoints, and improves the therapeutic effect.

[0023] Furthermore, the inflatable ball is made of silicone; the acupuncture component includes an electrode sheet fixedly bonded to the inflatable ball, and the controller is used to control the electrode sheet to electrically stimulate the skin.

[0024] Beneficial effects: The silicone material has good elasticity and softness, feels comfortable when in contact with the abdominal skin, and reduces the occurrence of skin allergies.

[0025] Furthermore, a polyamide fiber bonding layer is detachably connected to the user-facing side of the elastic bandage; a plurality of raised lines are provided on the side of the bonding layer away from the elastic bandage, and the raised lines are evenly distributed in a wavy shape.

[0026] Beneficial effects: The polyamide fiber material is high in strength and has the characteristics of being non-sweat-absorbent and breathable, which reduces the discomfort caused by sweat accumulation. The raised patterns can increase the friction between the fitting layer and the abdominal skin, thereby increasing the stability of fixation.

[0027] Furthermore, a plurality of magnets are embedded in the bonding layer, and the magnets are evenly distributed in a dot matrix; the thickness of the bonding layer is 0.5-1 mm.

[0028] Beneficial effects: The dot-matrix distributed magnets can generate a weak magnetic field around the abdomen when worn, and the vibration massage of the massage head can further promote blood circulation and metabolism in the abdomen.

DETAILED DESCRIPTION

[0037] The following is further described in detail through specific implementation methods: Example 1:

[0038] like Figure 1 The figure shows: a portable acupuncture and massage device, comprising a massager body 1, on which are provided a plurality of massage heads 2, one end of each of the massage heads 2 passes through the side wall of the massager body 1 and slides with the side wall of the massager body 1; the side wall of the massager body 1 is symmetrically provided with elastic straps 3, and an adjustment component for adjusting the tightness of the elastic straps 3 when worn is provided between adjacent elastic straps 3 away from the end of the massager body 1; the massage heads 2 are provided with a vibration component for driving the massage heads 2 to vibrate, and an adaptive adjustment component for adjusting the vibration intensity of the massage heads 2 according to the fat thickness at different positions of the user's abdomen; the massage heads 2 are also provided with a driving component for driving the vibration component to operate; the massager body 1 is provided with a fitting component for automatically fitting the user's abdomen when adjusting the tightness of the elastic straps 3; the massage heads 2 are also provided with an acupuncture component for performing acupuncture on the user during the vibration massage of the massage heads 2.

[0039] like Figure 3 As shown, specifically, the adjustment component includes a controller and an adjustment box 4, and a first driving member is fixedly connected to the inner wall of the adjustment box 4 by screws. The controller is used to control the rotation of the output shaft of the first driving member. In this embodiment, the first driving member is a DC motor 5; a gear 6 is coaxially fixedly connected to the output shaft of the DC motor 5 by screws, and a rack 7 is symmetrically and meshed on the gear 6. The rack 7 slides with the inner bottom wall and the inner top wall of the adjustment box 4 respectively, and one end of the rack 7 passes through the adjacent side wall of the adjustment box 4 and is integrally formed with a fixing ring, and the fixing ring is fixedly bonded to the adjacent elastic band 3.

[0040] When the user wears the massager body 1 on the abdomen, the controller controls the DC motor 5 to drive the gear 6 to rotate. The meshing transmission of the gear 6 and the rack 7 can make the racks 7 on both sides slide synchronously in opposite directions, and then drive the elastic strap 3 to tighten and loosen through the fixed ring. The elastic force of the elastic strap 3 itself can make it easier for obese users to quickly retract and release the elastic strap 3, thereby making it easier for users to quickly wear the massager body 1.

[0041] like Figure 4 and Figure 5 As shown, specifically, the vibration component includes a slide groove 8 opened on the inner wall of the massager body 1, a support block 9 is slidably fitted in the slide groove 8, the support block 9 and the bottom of the massage head 2 are integrally formed, a first connecting rod 10 is hinged on the side wall of the support block 9, a second connecting rod 11 is hinged on the side wall of the first connecting rod 10, and the second connecting rod 11 is symmetrical away from one end of the first connecting rod 10 and is hinged to a third connecting rod 12.

[0042] like Figure 2 and Figure 4 As shown, specifically, the adaptive adjustment component includes a sliding rod 13 hinged to the end of the first connecting rod 10 away from the support block 9, the end of the sliding rod 13 away from the first connecting rod 10 passes through the top wall of the massager body 1 and slides with the top wall of the massager body 1, the end of the sliding rod 13 away from the first connecting rod 10 is fixedly connected to the buffer block 14 by a screw, and a silicone suction cup 30 is fixedly bonded to the side wall of the buffer block 14 away from the sliding rod 13.

[0043] Combine Figure 4 As shown, when the user puts on the massager body 1, the massage head 2 and the buffer block 14 on the massager body 1 can fit the patient's abdominal skin, and at the same time, the silicone suction cup 30 on the buffer block 14 can absorb the user's abdominal skin, so that the sliding rod 13 can fit closely to the user's abdominal skin without falling off.

[0044] At this time, the driving assembly is used to drive the third connecting rod 12 to rotate. Due to the sliding cooperation between the support block 9 and the slide groove 8, the first connecting rod 10 and the second connecting rod 11 are hinged. Under the limiting effect of the slide bar 13 on the first connecting rod 10, the rotation of the third connecting rod 12 can drive the first connecting rod 10 and then drive the support block 9 to slide up and down in the slide groove 8. The support block 9 slides up and down and then drives the massage head 2 to slide up and down to perform vibration massage on the user's abdomen; when the fat thickness in a certain area of ​​the user's abdomen is thicker, the skin in this area is more protruding and less sensitive, so the slide bar 13 can be pushed to make the slide bar 13 move downward a greater distance, thereby driving the right end of the first connecting rod 10 to tilt downward. At this time, the third connecting rod 12 drives the left end of the first connecting rod 10 to do reciprocating up and down The stroke of movement increases, thereby increasing the stroke and strength of the vibration of the massage head 2, so that the massage head 2 can effectively massage the acupuncture points of the thicker skin in this area of ​​the user. On the contrary, the thinner skin on the abdomen of the user can drive the slide bar 13 to move downward a shorter distance, thereby driving the massage head 2 to vibrate and massage this area with less strength, thereby realizing that the adaptive adjustment component can automatically adjust the vibration intensity of the massage head 2 in the corresponding area according to the difference in fat thickness in different areas of the abdomen of obese users, breaking the limitation of the fixed strength mode of the existing device, so that each area can obtain an adaptive massage strength, thereby more accurately stimulating the abdominal acupuncture points and meridians, enhancing the effect of promoting blood circulation and regulating the functions of internal organs, and improving the efficiency of assisting fat loss.

[0045] like Figure 6 As shown, specifically, the driving assembly includes a second driving member and a first rotating shaft 16. The second driving member is fixedly connected to the inner bottom wall of the massager body 1 by screws. The controller is used to control the rotation of the output shaft of the second driving member. In this embodiment, the second driving member is a DC reduction motor 15; the output shaft of the DC reduction motor 15 is fixedly connected to the third connecting rod 12 adjacent to it by screws, and the output shaft of the DC reduction motor 15 is coaxially fixedly connected with a first pulley 17 by screws.

[0046] One end of the first rotating shaft 16 is rotatably engaged with the inner wall of the massager body 1, and the other end of the first rotating shaft 16 is fixedly connected to the third connecting rod 12 adjacent thereto by a screw. The first rotating shaft 16 is coaxially fixedly connected to the second pulley 18 by a screw, and belts are tensioned on the first pulley 17 and the second pulley 18.

[0047] Adjacent third connecting rods 12 are fixedly connected with second rotating shafts 19 by screws; a third rotating shaft 20 is symmetrically and rotatably matched on the inner wall of the massager body 1, and one end of the third rotating shaft 20 away from the inner wall of the massager body 1 is fixedly connected to the adjacent third connecting rod 12 by screws.

[0048] Combine Figure 6As shown, when the controller controls the direct current speed reducer motor 15 to rotate the output shaft, the first pulley 17 and the third connecting rod 12 adjacent thereto are rotated, the first pulley 17 rotates the first rotating shaft 16 through the belt, and since the second rotating shaft 19 is fixedly connected between the adjacent third connecting rods 12 by screws, the third connecting rod 12 drives all the second rotating shafts 19 to rotate and further drives all the third connecting rods 12 to rotate, the third rotating shaft 20 provides support for the rotation of the third connecting rod 12, so that it rotates stably, and only one power source can drive all the massage heads 2 to work independently, so that the structure is simplified, the stability of the device is increased, and the coordination of the vibration of the massage heads 2 is ensured.

[0049] As shown in Figure 1 and Figure 3 Specifically, the fitting assembly includes an annular air bag 21 fixedly bonded to the side wall of the massager main body 1, and a disc 22 coaxially fixedly connected to the side wall of the gear 6 away from the direct current motor 5; the disc 22 is eccentrically hinged with a crank 23, the crank 23 is hinged with a piston rod 24 at the end away from the disc 22, the piston rod 24 is integrally formed with a piston block at the end away from the crank 23, the piston block is slidably fitted with a first piston cylinder 25, the first piston cylinder 25 is fixedly connected to the inner bottom wall of the adjusting box 4 by screws, the side wall of the first piston cylinder 25 is communicated with an air inlet pipe and an air outlet pipe, the air inlet pipe and the air outlet pipe are communicated with one-way valves, the air inlet pipe is communicated with the outside of the adjusting box 4, the air outlet pipe is communicated with the annular air bag 21, and the annular air bag 21 is communicated with a deflation nozzle; the massage head 2 is provided with a finger pressure assembly for simulating manual finger pressing during massage.

[0050] As shown in Figure 3 When the user wears the massager main body 1 and adjusts the tightness of the elastic band 3 by the direct current motor 5, the direct current motor 5 can drive the gear 6 to rotate, the gear 6 drives the disc 22 to rotate synchronously, and through the cooperation of the crank 23, the piston rod 24 and the piston block, the piston block can do piston motion in the first piston cylinder 25, when the piston block moves downward, the pressure in the first piston cylinder 25 increases, under the action of the one-way valve in the air outlet pipe, the first piston cylinder 25 inflates the annular air bag 21, the annular air bag 21 expands synchronously at this time, adapts to the change of the abdominal contour, further fills the gap, increases the stability of the device, and the flexible contact of the annular air bag 21 can reduce the pressure on the abdominal skin.

[0051] When the piston block moves upward, the pressure in the first piston cylinder 25 decreases at this time, under the action of the one-way valve in the air inlet pipe, the air outside the adjusting box 4 enters the first piston cylinder 25 from the air inlet pipe at this time, so that the first piston cylinder 25 can continuously inflate the annular air bag 21.

[0052] As shown in Figure 4As shown, specifically, the acupressure assembly includes a push-pull rod 26 integrally formed at the bottom of the support block 9, and the massage head 2 is fixedly bonded with an inflatable ball 27 at one end away from the support block 9; a second piston cylinder 28 is provided below the push-pull rod 26, and the bottom end of the push-pull rod 26 passes through the top wall of the second piston cylinder 28 and extends into the second piston cylinder 28 and is integrally formed with a push block, and the push block and the inner wall of the second piston cylinder 28 are slidably matched; an air pipe is connected to the top of the second piston cylinder 28, and an exhaust hole is opened at the bottom of the second piston cylinder 28. The air pipe is connected to the inflatable ball 27 at one end away from the second piston cylinder 28, and the material of the inflatable ball 27 is silicone.

[0053] Combine Figure 4 As shown, when the support block 9 moves downward, the massage head 2 leaves the user's abdominal skin, and the push-pull rod 26 moves downward, driving the push block to move downward in the second piston cylinder 28. At this time, the space above the push block in the second piston cylinder 28 forms a negative pressure, and the space below is positive pressure (the positive pressure is discharged from the exhaust hole at the bottom of the second piston cylinder 28). At this time, the negative pressure can suck the gas in the inflatable ball 27 connected to the trachea at the top of the second piston cylinder 28 into the second piston cylinder 28; when the support block 9 moves upward, the massage head 2 presses the user's abdominal skin, and the push-pull rod 26 moves upward, driving the push block to move upward in the second piston cylinder 28. At this time, the second piston cylinder The space above the push block 28 forms a positive pressure, and the space below forms a negative pressure (the negative pressure sucks the gas outside the second piston cylinder 28 into the second piston cylinder 28 through the exhaust hole). At this time, the positive pressure can enter the interior of the inflatable ball 27 from the trachea, causing the inflatable ball 27 to expand and contact the user's abdominal skin together with the massage head 2. The inflatable ball 27 can expand gradually and press the skin before the massage head 2 contacts the abdominal skin. This massage technique of changing from deep to shallow can simulate the finger techniques of "combining pressing and kneading" and "progressive point pressure" in traditional Chinese medicine massage, making the entire massage process more in line with the rhythm and strength level of manual massage, thereby enhancing the physical comfort and therapeutic effect of obese users.

[0054] Specifically, the acupuncture assembly includes an electrode sheet fixedly bonded to the inflatable ball 27, and the controller is used to control the electrode sheet to electrically stimulate the skin.

[0055] A low-frequency current (typically 1-100Hz) output by the controller to the electrodes acts on abdominal acupuncture points and the skin surface, simulating the "qi" sensation (nerve reactions of soreness, numbness, swelling, and pain) experienced in traditional acupuncture. This principle is based on the integration of transcutaneous electrical nerve stimulation (TENS) and Traditional Chinese Medicine meridian theory: low-frequency current is transmitted through the skin to the subcutaneous tissue, stimulating the nerve endings and meridian system corresponding to the acupuncture points, activating the body's own analgesic mechanisms (such as promoting endorphin secretion), while also regulating local blood circulation and internal organ function, achieving an effect similar to acupuncture's "unblocking meridians and harmonizing qi and blood." The controller adjusts current parameters synchronously with the vibration intensity of the massage head 2 (e.g., increasing the current frequency or intensity as massage intensity increases), creating a synergistic effect between electrical stimulation and mechanical massage, enhancing the combined stimulation of the acupuncture points.

[0056] The specific implementation process is as follows: The user first positions the massager's main body 1 against the abdomen, stretches the 80-100cm long elastic bands 3 around the waist, and positions the adjustment box 4 at the end of the bands in the desired position behind the waist. The controller then activates a DC motor 5, rated at 12V and adjustable between 300-500 rpm. The motor's output shaft rotates a 2mm module gear 6, which meshes with a rack 7, causing the racks 7 to slide synchronously in opposite directions at a speed of 5-8cm / s. The elastic bands 3 are tightened via the retaining ring until the user feels the desired tightness (at this point, the tension in the bands is between 20-30N). The motor then turns off. During this process, the first piston cylinder 25 inflates the annular airbag 21, and the volume of the annular airbag 21 gradually expands from the initial 100mL to 150-200mL, automatically filling the gap between the massager body 1 and the abdomen due to fat accumulation, ensuring that the device fits tightly against the abdomen. At the same time, the silicone suction cup 30 on the buffer block 14 generates adsorption force, adsorbing on the abdominal skin to prevent the slide rod 13 from detaching.

[0057] The user then activates the DC reduction motor 15 via the controller, which rotates at a speed of 60-100 rpm. The output shaft of the DC reduction motor 15 drives all third connecting rods 12 to form a coordinated rotational motion. The rotation of the third connecting rods 12 drives the support block 9, which in turn drives the massage head 2 (with a diameter of 2.5 cm) up and down, initiating a vibration massage of the abdomen.

[0058] When the massage head 2 contacts different areas of the abdomen, if the fat thickness of a certain area reaches 3-5 cm, the skin protrusion will push the sliding rod 13 to move downward by 2-3 cm, so that the right end of the first connecting rod 10 inclines downward, and the reciprocating stroke of the left end of the first connecting rod 10 driven by the third connecting rod 12 increases from 2 cm to 3-4 cm, and the vibration amplitude and intensity of the massage head 2 are increased accordingly (the vibration frequency is kept at 30-50 Hz, and the impact force is between 5-8 N), so as to penetrate the thick fat layer to stimulate the acupoints; if the fat thickness of the area is 1-2 cm, the moving distance of the sliding rod 13 is only 0.5-1 cm, and the vibration intensity of the massage head 2 is correspondingly reduced (the impact force is between 2-3 N), so as to realize self-adaptive adjustment.

[0059] Meanwhile, during the sliding of the supporting block 9 up and down, when the supporting block 9 moves downward, the inflatable ball 27 contracts; when the supporting block 9 moves upward, the pushing block moves upward, so that the gas in the second piston cylinder 28 is pressed into the inflatable ball 27, the inflatable ball 27 expands and contacts the skin before the massage head 2, forming a "massage and kneading combined" method. After the massage is completed, the user starts the DC motor 5 in the reverse direction through the controller, loosens the elastic bandage 3, and removes the device. If the annular air bag 21 needs to be deflated, the deflation nozzle can be opened, so that the air bag releases the gas to the initial volume within 5 seconds.

[0060] The self-adaptive adjustment assembly can automatically adjust the vibration intensity of the massage head 2 corresponding to different areas of the abdomen of the obese user according to the fat thickness difference of different areas of the abdomen, breaks the limitation of the fixed intensity mode of the existing device, allows each area to obtain adaptive massage intensity, and thus more accurately stimulates the abdominal acupoints and meridians, enhances the effect of promoting blood circulation and regulating visceral function, and improves the efficiency of auxiliary fat reduction. Meanwhile, the cooperation of the elastic bandage 3, the adjustment assembly and the fitting assembly can adjust the tightness through the adjustment assembly and automatically adapt to the abdominal contour through the fitting assembly when worn, fills the gap caused by fat accumulation, and greatly improves the fitting degree of the device and the abdomen.

[0061] Embodiment 2:

[0062] As shown in the accompanying Figure 1 embodiment 1, the difference is that the side wall of the elastic bandage 3 facing the user is detachably connected with a fitting layer made of polyamide fiber material; a plurality of raised patterns are arranged on the side wall of the fitting layer away from the elastic bandage 3, and the raised patterns are evenly distributed in a wavy shape.

[0063] The specific implementation process is as follows: The polyamide fiber material of the fitting layer has high strength, does not absorb sweat and has the characteristics of air permeability, which can reduce the discomfort caused by sweat accumulation when the elastic bandage 3 contacts the skin. Meanwhile, the detachable connection of the fitting layer can be easily cleaned by the user, and the raised patterns on the fitting layer can increase the friction between the fitting layer and the abdominal skin, thereby increasing the stability of the fixation of the elastic bandage 3.

[0064] Example 3:

[0065] As attached Figure 1 As shown, the difference from Example 2 is that a number of magnets are embedded in the bonding layer, and the magnets are evenly distributed in a dot matrix; the thickness of the bonding layer is 1 mm.

[0066] The specific implementation process is as follows: The magnets distributed in a dot matrix inside the fitting layer of the elastic bandage 3 can generate a weak magnetic field around the abdomen when worn, and cooperate with the vibration massage of the massage head 2 to further promote blood circulation and metabolism in the abdomen.

[0067] Embodiment 4:

[0068] As attached Figure 1 As shown, the difference from Example 3 is that in this embodiment, the portable acupuncture and massage device of the present invention is equipped with a portable storage backpack. The portable storage backpack is made of lightweight waterproof nylon and weighs 300g. It has a custom-shaped buffer compartment (25cm×18cm×8cm) that conforms to the contours of the massager body 1. The custom-shaped buffer compartment is filled with high-density sponge to secure the massager body 1 and prevent component wear caused by bumps during transportation. Elastic mesh pockets are located on both sides of the custom-shaped buffer compartment to store the elastic strap 3 (which can be compressed to 20cm in length when stored) and the charging cable (the device is equipped with a 1000mAh lithium battery that supports Type-C fast charging and can operate continuously for 2-3 hours when fully charged). A zippered hidden pocket is installed on the outside of the portable storage backpack. When stored, the backpack has a volume of only 30cm×22cm×10cm, which can be placed in a handbag, backpack, or suitcase.

[0069] In addition, the shoulder strap on the portable storage backpack is adjustable (length ranges from 40-80cm), allowing for both shoulder and hand carry. The surface is treated with an anti-fouling coating, allowing for quick cleaning of stains during daily use. This portable design allows users to remove the device and wear it at any time, whether at home, in the office, or while traveling, without being restricted by location. This enables "portable physical therapy on the go," solving the problem of traditional large-scale physical therapy equipment being difficult to move and limiting its use in certain scenarios, further enhancing the device's practicality and user acceptance.

[0070] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
