DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0040] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0041] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure.

Therefore, the example term "below..." can include both upper and lower orientations. The device can be oriented otherwise (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0042] like Figure 1-Figure 4 as well as Fig. 9 As shown, the fat grinding device 1 according to the embodiment of the present invention includes a frame 10, a fat grinding assembly, a driving assembly and two sets of transmission assemblies 40.

[0043] Specifically, the frame 10 defines an installation cavity 11 and an escape opening 12 connected to the installation cavity 11; the grease grinding assembly is reciprocatably arranged on the frame 10, and the grease grinding assembly includes a bracket 21 and a first massage part 22 arranged on the bracket 21, and a portion of the bracket 21 passes through the escape opening 12 to support the first massage part 22; the drive assembly and the transmission assembly 40 are both arranged in the installation cavity 11, and the two groups of transmission assemblies 40 are arranged side by side on the frame 10, and the drive assembly is simultaneously connected to the two groups of transmission assemblies 40, and the two groups of transmission assemblies 40 are both connected to the grease grinding assembly.

[0044] Specifically, the driving assembly drives the fat grinding assembly to move through the transmission assembly 40, that is, the driving assembly drives the bracket 21 to move along the avoidance opening 12, so that the first massage part 22 moves along the frame 10, and the driving assembly provides power for the movement of the first massage part 22. The two sets of transmission assemblies 40 are respectively connected to the two ends of the fat grinding assembly, so that when the driving assembly drives the fat grinding assembly to move along the frame 10, it can be more stable to prevent jamming.

[0045] It is understandable that a portion of the bracket 21, the drive assembly and the transmission assembly 40 are all disposed in the installation cavity 11, which can protect the user and also protect and limit the above-mentioned mechanism. Another portion of the bracket 21 passes through the avoidance opening 12, thereby connecting with the first massage part 22 located outside the installation cavity 11.

[0046] In some embodiments, the first massage part 22 includes a plurality of first massage protrusions, and the plurality of first massage protrusions are evenly distributed, so that the massage effect of the first massage part 22 can be enhanced during the movement of the first massage part 22 .

[0047] In some embodiments, the first massage part 22 includes a shell, and a guide groove is provided on the shell to facilitate the user to introduce some nutrient solution during massage.

[0048] The avoidance opening 12 extends along the length direction of the frame 10, or the avoidance opening may extend along the width direction of the frame 10. For example, in a specific embodiment, the avoidance opening 12 extends along the length direction of the frame 10, and the two sets of transmission components 40 are respectively arranged at both ends of the width direction of the frame 10.

[0049] like Figure 1-Figure 4 As shown, in some embodiments, the first massage part 22 includes a plurality of rollers 222, and a plurality of first massage protrusions are provided on the rollers 222. When the first massage part 22 moves with the bracket 21, the rollers 222 themselves also rotate simultaneously.

[0050] in, Figure 1 and Figure 2 The fat grinding device 1 of the first embodiment, Figure 3 and Figure 4 This is the fat grinding device 1 of the second embodiment, wherein the arrangement of the roller 222 of the fat grinding device 1 of the first embodiment is different from the arrangement of the roller 222 of the fat grinding device 1 of the second embodiment, and can be selected according to needs.

[0051] like Figure 1-Figure 4 As shown, according to the fat rolling device 1 of the embodiment of the present invention, the driving component drives the first massage part 22 to move along the length direction of the avoidance opening 12 through the transmission component 40. By changing the rotation direction of the transmission component 40, the moving direction of the first massage part 22 can be changed, so that the first massage part 22 can move back and forth along the frame 10. When the frame 10 is close to the user so that the roller 222 contacts the user's skin, the first massage part 22 can automatically reciprocate and roll the user's skin, thereby saving the user's physical strength in operation and improving the user's convenience.

[0052] like Figure 4 and Figure 5 As shown, according to the fat grinding machine 1 of the embodiment of the present invention, the driving assembly includes a first driving part 30, a transmission rod 33, a worm wheel 32 and a worm 31. The transmission rod 33 is rotatably provided on the frame 10, and the worm wheel 32 is fixed on the transmission rod 33. The first driving part 30 is transmission-connected to the worm 31, and the worm 31 is transmission-connected to the worm wheel 32 at the same time. The two ends of the transmission rod 33 are fixedly connected with driving wheels 41, and the driving wheel 41 is meshed with the transmission assembly 40.

[0053] That is to say, the first driving part 30 drives the worm 31 to rotate, and the worm 31 is connected to the worm wheel 32 in transmission. That is to say, the worm 31 can directly mesh with the worm wheel 32, or can be driven through a transmission wheel set. The rotation of the worm 31 drives the worm wheel 32 to rotate, and the worm wheel 32 is fixed on the transmission rod 33. The worm wheel 32 drives the transmission rod 33 to rotate. The two ends of the transmission rod 33 are fixedly connected with a driving wheel 41. The rotation of the transmission rod 33 drives the driving wheel 41 to rotate, and the rotation of the driving wheel 41 drives the transmission assembly 40 to move.

[0054] The meshing transmission between the worm wheel 32 and the worm 31 is a multi-tooth meshing transmission, which can obtain a large transmission ratio, stable transmission and low noise.

[0055] In some embodiments, the first driving unit 30 is configured as a motor. By changing the direction of rotation of the motor, the rotation direction of the driving wheel 41 can be changed.

[0056] like Fig. 9 As shown, in some embodiments, the transmission assembly 40 includes a tensioning portion 45 and a transmission belt. The tensioning portion 45 is rotatably disposed on the frame 10. The driving wheel 41 and the tensioning portion 45 are spaced apart. The transmission belt is simultaneously mounted on the driving wheel 41 and the tensioning portion 45. The transmission belt is connected to the bracket 21.

[0057] like Fig. 9 As shown, in some embodiments, the transmission belt is tensioned by the driving wheel 41 and the tensioning portion 45 , the driving wheel 41 rotates to drive the transmission belt to rotate, and the rotation of the transmission belt drives the bracket 21 to move along the frame 10 .

[0058] In some embodiments, the transmission belt includes one of a synchronous belt, a chain, and a flexible rope. The transmission belt and the drive wheel 41 cooperate to form a belt transmission method, which has a simple structure, stable transmission, and can buffer and absorb vibration. When the transmission belt is configured as a synchronous belt, the synchronous belt transmits power by the friction between the synchronous belt and the drive wheel 41; when the transmission belt is configured as a flexible rope, the flexible rope transmits power by the friction between the flexible rope and the drive wheel 41; when the transmission belt is configured as a chain, the chain transmits power by meshing with the drive wheel 41.

[0059] like Fig. 9 As shown, in some embodiments, a plurality of support wheels 60 are further provided in the installation cavity 11, and the plurality of support wheels 60 are spaced apart between the driving wheel 41 and the tensioning portion 45, and the transmission belt is simultaneously sleeved outside the plurality of support wheels 60. By providing the support wheels 60, the transmission belt can be supported to prevent the transmission belt from interfering with other components during rotation, especially when the shape of the bracket 21 is arc-shaped, by providing the support wheels 60, the distribution position of the transmission belt after tensioning can be adjusted.

[0060] In some embodiments, the transmission assembly 40 includes a rack, the rack is disposed on the frame 10, the driving assembly is disposed on the bracket 21, and the driving wheel 41 is engaged with the rack.

[0061] In some embodiments, the driving unit 30 is configured as an electric motor, and a transmission gear is sleeved on the output shaft of the electric motor, and the transmission gear is meshed with the driving wheel 41 .

[0062] In some embodiments, the driving wheel 41 rotates so that the driving wheel 41 and the rack move relative to each other. Since the rack is fixedly connected to the frame 10, the driving wheel 41 moves along the rack, and the bracket 21 is connected to the driving wheel 41. In this way, the bracket 21 moves along the rack with the driving wheel 41, thereby realizing the movement of the first massage part 22 along the frame 10.

[0063] Among them, when the first driving part 30 is a motor, the rotation direction of the driving wheel 41 can be changed by changing the direction of the motor. After the rotation direction of the driving wheel 41 is changed, the moving direction of the driving wheel 41 relative to the rack is changed, thereby realizing the reciprocating movement of the first massage part 22 along the frame 10.

[0064] The rack is fixedly connected to the frame 10, which may be bolted, clamped, welded or integrally formed.

[0065] like Figure 4 As shown, in some embodiments, a first clamping portion 16 is provided in the installation cavity 11 , and a second clamping portion 214 is provided on the bracket 21 . The second clamping portion 214 is movably clamped with the first clamping portion 16 .

[0066] When the bracket 21 moves with the transmission belt, the second clamping portion 214 and the first clamping portion 16 move relative to each other, thereby guiding the movement of the bracket 21 through the limiting cooperation between the second clamping portion 214 and the first clamping portion 16, so that the bracket 21 can move along a predetermined track to prevent deviation and interference with other components. The second clamping portion 214 can be configured as a groove or a convex track.

[0067] When the frame 10 extends along a straight line, the first clamping portion 16 extends along a straight line; when the frame 10 extends along an arc, the first clamping portion 16 extends along the arc; when the frame 10 extends along a curved wave curve, the first clamping portion 16 extends along the curved wave curve.

[0068] Since the human body is curved and not a fixed plane, when the roller 222 contacts the user's skin, the curve and the thickness of subcutaneous fat will affect the contact between the roller 222 and the skin as the position changes. If the distance between the roller 222 and the skin is adjusted to remain unchanged, the user may feel that the pressure of the roller 222 is not enough in some parts, and the user may feel that the pressure of the roller 222 is too large in some parts. In some embodiments, a movable support part 212 is provided on the bracket 21, and the first massage part 22 is provided on the support part 212. The support part 212 can be movably connected to the bracket 21, or can be hinged to the bracket 21, such as Fig.10 As shown, when the support part 212 is hinged to the bracket 21, the support part 212 can rotate relative to the bracket 21, and the pressing force between the first massage part 22 and the skin can be adaptively adjusted.

[0069] An elastic member 213 is sandwiched between the bracket 21 and the supporting portion 212. The elastic member 213 is deformable, and the avoidance opening 12 extends along the length direction of the frame 10. In this way, the elastic member 213 enables the first massage part 22 to always be in close contact with the user's skin, and the pressing force between the first massage part 22 and the skin can be adaptively adjusted. When the skin curvature is large, the first massage part 22 is subjected to a large force, thereby compressing the elastic member 213 to a large extent. When the skin curvature is small, the first massage part 22 is subjected to a small force, thereby causing the elastic member 213 to be subjected to a small force, and stretching to a certain extent to make the first massage part 22 in close contact with the user's skin.

[0070] The elastic member 213 may be configured as a coil spring, a rubber spring, a torsion spring, or the like.

[0071] like Figure 7 and Figure 8 As shown, in some embodiments, the elastic member 213 is configured as a spring 2131, a second guide groove 15 is provided on the bracket 21, a first limiting portion 211 is fixedly connected to the wall of the second guide groove 15, the support portion 212 includes a support rod 2120, the support rod 2120 is movably inserted into the second guide groove 15, a second limiting portion 2121 is provided on the support rod 2120, the first limiting portion 211 is located between the second limiting portion 2121 and the first massage portion 22, and the spring 2131 is provided on the side of the second limiting portion 2121 away from the first limiting portion 211.

[0072] In detail, the first limiting portion 211 and the second limiting portion 2121 limit the spring 2131. When the support rod 2120 moves toward the direction close to the installation cavity 11, the distance between the first limiting portion 211 and the second limiting portion 2121 will be shortened, and the spring 2131 will be jointly compressed. When the support rod 2120 moves along the axial direction of the second guide groove 15 toward the direction away from the installation cavity 11, the spring 2131 gradually returns to its original position, and the first limiting portion 211 prevents the support rod 2120 from slipping out of the second guide groove 15.

[0073] like Figure 6 As shown, in some embodiments, at least one guide post 215 is provided on one of the bracket 21 and the support portion 212 , and at least one matching groove is provided on the support portion 212 , and the guide post 215 is inserted into the matching groove.

[0074] like Figure 6 As shown, in some embodiments, while the support rod 2120 moves along the second guide groove 15, the guide column 215 moves along the mating groove, so that the cooperation between the guide column 215 and the mating groove plays a role in positioning and guiding the support rod 2120, preventing the support rod 2120 from getting stuck in the second guide groove 15.

[0075] like Figure 2 and Figure 3 As shown, in some embodiments, a third guide groove 13 is provided on the outer wall of the frame 10 , and the third guide groove 13 extends along the length direction of the frame 10 . When the spring 2131 is compressed, part of the first massage part 22 can be retracted into the third guide groove 13 .

[0076] It is understandable that the third guide groove 13 enables the first massage part 22 to retract when it moves to any position and encounters skin resistance according to a predetermined trajectory during movement, thereby providing an avoidance space for the retraction of the first massage part 22 .

[0077] The width of the third guide groove 13 is greater than the width of the first massage part 22. When the elastic member 213 is compressed, the height of the first massage part 22 exposed in the third guide groove 13 is H, and H satisfies: 15mm≤H≤50mm, wherein H can be 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, etc.

[0078] like Figure 1-Figure 4 As shown, according to the fat grinding device 1 of the embodiment of the present invention, the frame 10 includes two second frames 102 arranged opposite to each other, the second frames 102 are arranged in an arc shape, and the second frames 102 are provided with a mounting cavity 11 and a fat grinding assembly.

[0079] In some embodiments, the frame 10 further includes a first frame body 101 , and two ends of the first frame body 101 are hinged to the second frame body 102 respectively.

[0080] In this way, the frame 10 can be more closely fitted to the human body. When the user uses the fat grinding device 1, the user only needs to put the fat grinding device 1 on the part of the user where the fat is to be used, and the fat can be crushed without the need for hand support. The first frame 101 and the second frame 102 are hinged, so that the frame 10 can be adapted to different curvatures of the human body or different parts of the same user.

[0081] like Figure 1 and Figure 2 As shown, in some embodiments, the free ends of the two second frames 102 are each provided with a connecting portion 50 , and the two connecting portions 50 can be connected.

[0082] The two connecting parts 50 can be directly connected or indirectly connected. In this way, when the fat grinding device 1 is not needed, the fat grinding device 1 can be folded up by connecting the two connecting parts 50.

[0083] When the fat grinding device 1 is in the folded state, the two second frames 102 are close to each other, and the two connecting parts 50 are connected. When the fat grinding device 1 needs to be used, the two connecting parts 50 are disengaged, the two second frames 102 are opened away from each other, and the fat grinding device 1 is put on the user's waist, legs or arms for massage. Since the second frame 102 and the first frame 101 are hinged, the fat grinding device 1 can adapt to body parts with different curvatures.

[0084] like Figure 1-Figure 4 As shown, in some embodiments, a second massage part 1011 is provided on one side of the first frame 101 close to the first massage part 22, and a plurality of second massage protrusions 10111 are provided on the second massage part 1011. In this way, when the first massage part 22 moves on the frame 10, the first frame 101 hinged to the second frame 102 will be driven to produce slight vibration, and the first frame 101 will transmit the vibration to the second massage part 1011, driving the second massage part 1011 to massage and soothe the body.

[0085] In some embodiments, an energy emitting device is disposed in the support 21 or the first massage part 22 .

[0086] like Fig. 9 As shown, in some embodiments, a controller and two detection switches 70 are provided in the installation cavity 11. The two detection switches 70 are respectively provided at both ends of the length direction of the avoidance opening 12. The detection switches 70, the energy emitting device and the first driving unit 30 are all electrically connected to the controller.

[0087] like Fig. 9As shown, in some embodiments, a controller and two detection switches 70 are provided in the installation cavity 11. The two detection switches 70 are respectively provided at both ends of the length direction of the avoidance opening 12. The detection switches 70 are electrically connected to the controller, and the controller is also electrically connected to the first driving unit 30.

[0088] In some embodiments, when the bracket 21 moves to trigger one of the detection switches 70, the detection switch 70 sends travel information to the controller. After receiving the travel information, the controller determines that the bracket 21 has moved to one end of the avoidance opening 12, and the controller controls the output shaft of the first drive unit 30 to change the rotation direction, driving the bracket 21 to move along the avoidance opening 12 toward the other end. When the bracket 21 moves to trigger another detection switch 70, the detection switch 70 sends travel information to the controller, and the controller controls the output shaft of the first drive unit 30 to change the rotation direction, driving the bracket 21 to move toward one end of the avoidance opening 12.

[0089] In some embodiments, an energy transmitting device is provided in the bracket 21 or the first massage part 22, and the energy transmitting device is electrically connected to the controller. When the fat grinding device 1 is close to the user's skin or in contact with the user's skin, a high energy beam can be emitted through the energy transmitting device to act on the human skin. As the bracket 21 moves, the energy transmitting device can reciprocate along the frame 10, and the high energy beam emitted by the energy transmitting device can act on the user's skin in a dispersed manner, preventing the high energy beam from being concentrated at one point and causing burns to the user's skin or muscles.

[0090] The controller is electrically connected to the energy emitting device. When the energy emitting device is capable of emitting more than one energy beam, the controller can control the generation and emission cycle of each energy beam. For example, by controlling the frequency cycle of pulsed microcurrent, the controller can simulate the feeling of hand massage to a certain extent.

[0091] According to the fat grinding device 1 of the embodiment of the present invention, the energy emitting device includes at least one of a microcurrent generator, an ultrasonic generator, a laser generator, a photon generator, an ion generator and an infrared generator.

[0092] In some embodiments, the first massage part 22 includes a plurality of rollers 222 , and the massage assembly 20 further includes a first sensor, which is electrically connected to the controller and is used to detect the displacement of the bracket 21 or the rotation angle of the roller 222 .

[0093] Among them, the first sensor is used to detect the displacement of the bracket 21 or the rotation angle of the roller 222, and judge the movement displacement of the energy transmitting device by the displacement of the bracket 21 or the rotation angle of the roller 222, so as to control the period of energy beam emission by the energy transmitting device, avoid the energy beam acting on the human skin too concentratedly, and prevent the user's skin or muscle burns.

[0094] When the first sensor is used to detect the displacement of the bracket 21 , the first sensor is configured as a displacement sensor. When the first sensor is used to detect the rotation angle of the roller 222 , the first sensor is configured as an angle sensor.

[0095] In some embodiments, the massage component 20 also includes a second sensor, which is electrically connected to the controller. The first drive unit 30 is configured as a motor, and a second sensor is provided on the output shaft of the motor. The second sensor is used to detect the rotation angle of the motor. The movement displacement of the energy emitting device is judged by the rotation angle of the motor, thereby controlling the period of the energy emitting device emitting the energy beam to avoid the energy beam acting on the human skin being too concentrated, thereby preventing the user from skin burns or muscle burns.

[0096] In some embodiments, a second driving unit is further disposed in the first frame 101 , and the second driving unit is transmission-connected to the second massage unit 1011 to drive the second massage unit 1011 to rotate.
