DETAILED DESCRIPTION

[0038] 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.

[0039] 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.

[0040] 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. For example, if the device in the figure undergoes a position flip or a change in posture or a change in motion state, then these directional indications will also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". 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.

[0041] like Figure 1-Figure 4 As shown, the fat grinding device 1 according to the embodiment of the present invention includes a frame 10, a fat grinding assembly 20, a driving assembly 30 and a transmission assembly 40.

[0042] Specifically, the frame 10 defines an installation cavity and an escape opening 12 connected to the installation cavity, the escape opening 12 extends along the length direction of the frame 10, and the frame 10 defines a closed loop track 13, the closed loop track 13 includes a first track 131 and a second track 132 distributed in sequence along the thickness direction of the frame 10, and both ends of the first track 131 are connected to the second track 132; the grease grinding component 20 is reciprocatingly arranged on the frame 10, the grease grinding component 20 includes a bracket 21 and a first massage part 22 arranged on the bracket 21, a part of the bracket 21 passes through the escape opening 12 to support the first massage part 22, and a first sliding part 2121 is provided on the bracket 21, and the first sliding part 2121 is movably embedded in the closed loop track 13; the driving component 30 and the transmission component 40 are both arranged in the installation cavity, and the driving component 30, the transmission component 40 and the grease grinding component 20 are sequentially connected in transmission.

[0043] In detail, the driving assembly 30, the transmission assembly 40 and the grease grinding assembly 20 are sequentially connected in transmission. The driving assembly 30 drives the grease grinding assembly 20 to move through the transmission assembly 40. The driving assembly 30 provides power for the movement of the grease grinding assembly 20, and the movement of the bracket 21 drives the first sliding part 2121 to move along the closed loop track 13. The closed loop track 13 includes a first track 131 and a second track 132 sequentially distributed along the thickness direction of the frame 10. Both ends of the first track 131 are connected to the second track 132. Taking the case where the first sliding part 2121 is in the first track 131 as an example, the first sliding part 2121 moves in the first track 131 to one end of the first track 131, and the transmission assembly 40 changes the rotation direction. The first sliding part 2121 enters the second track 132 and moves toward the first track. The first sliding part 2121 moves to the other end of the first track 131, the transmission assembly 40 changes the rotation direction, and the first sliding part 2121 moves in the first track 131 toward one end of the first track 131, and so on. The first track 131 and the second track 132 are sequentially distributed along the thickness direction of the frame 10, so that the first sliding part 2121 drives the bracket 21 to move relative to the frame 10, so that the distance between the first massage part 22 and the frame 10 changes. In the process of the fat grinding device 1 massaging the user, the squeezing force of the first massage part 22 on the user's skin changes, thereby achieving periodic light-heavy-light, or heavy-light-heavy massage intensity for the user, thereby improving the massage effect of the fat grinding device 1, with a simple structure and cost savings.

[0044] It should be noted that by changing the transmission direction of the drive component 30 to the transmission component 40, the driving direction of the grease grinding component 20 by the transmission component 40 can be changed. For example, when the drive component 30 includes a motor, the moving direction of the grease grinding component 20 can be changed by changing the rotation direction of the output shaft of the motor.

[0045] like Figure 5 ,like Figure 8 , Fig. 9 as well as Fig.10 As shown, in some embodiments, the first massage part 22 includes at least one roller 222, and the roller 222 is provided with a plurality of first massage protrusions, which can enhance the massage effect of the first massage part 22. Figure 1 The configuration of the roller 222 in the first embodiment is shown. Figure 8 and Fig. 9 The configuration of the roller 222 in the second embodiment is shown. Fig.10 The configuration of the roller 222 in the third embodiment is shown.

[0046] like Figure 3 and Figure 4 As shown, in some embodiments, the driving assembly 30 includes a first driving portion 31 .

[0047] like Fig. 9 and Fig.10 The avoidance opening 12 is shown. According to the fat grinding device 1 of the embodiment of the present invention, the driving assembly 30 drives the first massage part 22 to move along the avoidance opening 12 through the transmission assembly 40. By changing the rotation direction of the transmission assembly 40, the moving direction of the first massage part 22 can be changed, so that the first sliding part 2121 can reciprocate along the frame 10 in the order of the first track 131-the second track 132-the first track 131-the second track 132 or the second track 132-the first track 131-the second track 132-the first track 131 Since the first track 131 and the second track 132 are distributed along the thickness direction of the frame 10, the distance between the first massage part 22 and the frame 10 changes, that is, when the first sliding part 2121 slides in the first track 131 and when the first sliding part 2121 slides in the second track 132, the distance between the first massage part 22 and the frame 10 is different. In this way, when the fat grinding device 1 contacts the human skin, the pressing force on the human skin will be different, thereby changing the massage force of the first massage part 22 on the user, with a simple structure and cost saving.

[0048] like Figure 6 and Figure 7 As shown, in some embodiments, a closed loop track 13 is provided at both ends of the width direction of the frame 10, and a first sliding portion 2121 is provided at both ends of the bracket 21, and the first sliding portions 2121 are embedded in adjacent closed loop tracks 13. In this way, when the driving assembly 30 drives the grease grinding assembly 20 to move, the two first sliding portions 2121 on the bracket 21 can be subjected to more balanced forces, which can further prevent the first sliding portions 2121 from getting stuck with the closed loop track 13.

[0049] like Figure 8-Figure 10 As shown, in some embodiments, the frame 10 includes a first frame 101 and second frames 102 respectively arranged at both ends of the first frame 101, the first frame 101 and the second frame 102 are hinged, the two second frames 102 are bent in a direction of approaching each other, and the second frame 102 is provided with a mounting cavity and a massage component. In this way, the frame 10 can be more fitted to the human body. When the user uses the fat grinding instrument 1, the fat grinding instrument 1 only needs to be placed on the user's part that needs to be massaged, and can be fixed without hand support, and the fat can be automatically rolled and massaged. The first frame 101 and the second frame 102 are hinged, so that the angle between the first frame 101 and the second frame 102 can be changed, so that the frame 10 can adapt to human bodies with different curvatures or different parts of the same user.

[0050] like Fig.10 and Fig.11 As shown, in some embodiments, the fat grinding device 1 includes a hinge 17, and the hinge 17 includes a first connection part 171 and a second connection part 172 respectively arranged at both ends of the rotating shaft 173, the first connection part 171 is connected to the first frame 101, and the second connection part 172 is connected to the second frame 102, the hinge 17 is a metal part, and a torsion spring 174 is sleeved on the rotating shaft 173, and the two ends of the torsion spring 174 are respectively against the first connection part 171 and the second connection part 172, so that the fat grinding device 1 has a folded state and an unfolded state. When it is not needed, the fat grinding device 1 can be folded by pressing the two second frames 102. When it is needed, the two second frames 102 can be unfolded. When the fat grinding device 1 is in the unfolded state, the torsion spring 174 keeps the second frame 102 in the unfolded state.

[0051] 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, during the movement of the roller 222, the massager as a whole will be driven to produce slight vibrations on the skin, so that the second massage protrusions 10111 can have a massage effect on the user, thereby enhancing the comfort of using the massager.

[0052] like Figure 8-Figure 9 As shown, in some embodiments, a second driving unit is provided in the first frame 101, and the second driving unit is transmission-connected with the second massage part 1011 to drive the second massage part 1011 to rotate. By controlling the second driving unit, the second massage part 1011 can be controlled to rotate, and the second driving unit provides power for the rotation of the second massage part 1011, wherein the second driving unit can be configured as a motor.

[0053] like Figure 8-Figure 9As shown, in some embodiments, a clamping member 50 is provided at the free end of the second frame 102. In this way, the fat grinding device 1 can be clamped and received by the two clamping members 50 when not in use.

[0054] According to the fat grinding device 1 of the embodiment of the present invention, the first track 131 includes a first main track 1311 and a first guide section 1312, both ends of the first main track 1311 are respectively connected to the first guide section 1312, the other end of the first guide section 1312 is connected to the second track 132, and the first main track 1311 and the second track 132 are arranged side by side.

[0055] That is to say, the two ends of the first main rail 1311 are respectively connected to the first guide section 1312, and the first sliding part 2121 slides in the first main rail 1311 to the first guide section 1312, and is guided to the second rail 132 through the first guide section 1312, or the first sliding part 2121 moves in the second rail 132, and after changing the moving direction, is guided to the first main rail 1311 through the first guide section 1312.

[0056] The first main track 1311 and the second track 132 are arranged side by side, which can simplify the structural arrangement of the first track 131 and the second track 132 and reduce processing errors. In addition, it can also ensure that the first massage part 22 continues to exert a certain force for a certain period of time before changing the force, which can improve the massage effect.

[0057] like Figure 1 and Figure 2 As shown, according to the fat grinding device 1 of the embodiment of the present invention, the first track 131 includes a first main track 1311 and a first guide section 1312, and the two ends of the first main track 1311 are respectively connected to the first guide section 1312, and the second track 132 includes a second main track 1321 and a second guide section 1322, and the two ends of the second main track 1321 are respectively connected to the second guide section 1322, and the other end of the first guide section 1312 is connected to the other end of the adjacent second guide section 1322, and the first main track 1311 and the second main track 1321 are parallel.

[0058] Specifically, the two ends of the first main track 1311 are respectively connected to the first guide segments 1312, and the two ends of the second main track 1321 are respectively connected to the second guide segments 1322. The first sliding part 2121 slides in the first main track 1311 to the first guide segment 1312, and is guided to the second guide segment 1322 by the first guide segment 1312. After the first sliding part 2121 changes its moving direction, the first sliding part 2121 moves along the second guide segment 1322 to the second main track 1321, and moves from the second main track 1321 to another second guide segment 1322, and moves from another second guide segment 1322 to the first guide segment 1312. After the first sliding part 2121 changes its moving direction, the first sliding part 2121 moves along the other first guide segment 1312 to the first main track 1311, and the cycle is repeated.

[0059] The parallelism between the first main track 1311 and the second main track 1321 can simplify the structural setting of the first track 131 and the second track 132 and reduce processing errors. In addition, it can also ensure that the first massage part 22 continues to exert a certain force for a certain period of time before changing the force, which can improve the massage effect.

[0060] In some embodiments, the angle ɑ between the central axis of the extension direction of the first guide segment 1312 and the central axis of the extension direction of the frame 10 satisfies: 0°<ɑ≤20°.

[0061] It can be understood that a suitable size of ɑ can make the first sliding part 2121 smoothly transition between the first main track 1311 and the second track 132, and prevent the first sliding part 2121 from getting stuck. ɑ can be 2°, 4°, 6°, 8°, 10°, 12°, 14°, 16°, 18°, 20°, etc.

[0062] In some embodiments, an angle β between a central axis of the second guide segment 1322 in the extension direction and a central axis of the frame 10 in the extension direction satisfies: 0°<β≤20°.

[0063] It is understandable that a suitable value of β can make the first sliding portion 2121 smoothly transition between the first main track 1311 and the second track 132, and prevent the first sliding portion 2121 from getting stuck. β can be 2°, 4°, 6°, 8°, 10°, 12°, 14°, 16°, 18°, 20°, etc.

[0064] like Figure 1 and Figure 2 As shown, according to the fat grinding device 1 according to the embodiment of the present invention, the closed loop track 13 also includes a transition track 133 , both ends of the second track 132 are provided with transition tracks 133 , and the transition track 133 is connected to both the first track 131 and the second track 132 .

[0065] The length of the first sliding part 2121 extends along the moving direction of the first sliding part 2121. The first sliding part 2121 can support the bracket 21. The first sliding part 2121 is set to have a certain length, so that the bracket 21 is more stable during the movement and avoids shaking. Since the first sliding part 2121 has a certain length, a transition track 133 is set to facilitate the first sliding part 2121 to completely move into the transition track 133 and then change the moving direction, so as to facilitate switching between the first track 131 and the second track 132, and avoid the first sliding part 2121 from getting stuck when switching between the first track 131 and the second track 132.

[0066] In some embodiments, the length of the transition track 133 is set to be greater than the length of the first sliding portion 2121, so that the first sliding portion 2121 can completely enter the transition track 133 and then change the moving direction to avoid jamming.

[0067] like Figure 1 , Figure 2 , Fig.12 as well as Fig.13 As shown, in some embodiments, the transition track 133 is configured as one of a U-shape, an arc shape, and a straight line shape. Fig.12 and Fig.13 In the embodiment of FIG. 1 , the transition track 133 is configured as a U-shape.

[0068] like Figure 1 and Figure 2 As shown, according to the fat grinding machine 1 of the embodiment of the present invention, a rack 14 is provided in the installation cavity, the rack 14 is fixedly connected to the frame 10, the driving assembly 30 and the transmission assembly 40 are both arranged on the bracket 21, and the transmission assembly 40 includes a driving wheel 41, which is meshed with the rack 14.

[0069] The driving wheel 41 rotates under the drive of the driving assembly 30, and the driving wheel 41 and the rack 14 move relative to each other, and the rack 14 is fixedly connected to the frame 10, so that the driving wheel 41 drives the bracket 21 to move, thereby causing the driving assembly 30 and the transmission assembly 40 and the first sliding part 2121 to move with the bracket 21.

[0070] The rack 14 is fixedly connected to the frame 10 , which may be bolted, clamped, welded or integrally formed.

[0071] In some embodiments, the first driving part 31 is configured as an electric motor, the driving wheel 41 is sleeved on the output shaft of the electric motor, and a protective part is provided on the bracket 21. The protective part defines an accommodating cavity, and the driving wheel 41 is located in the accommodating cavity. In this way, the driving wheel 41 can be protected by the protective part to prevent the driving wheel 41 from interfering with other components during rotation.

[0072] In some embodiments, when projected on a plane or curved surface parallel to the length direction of the bracket 21, the symmetric centerline of the extension direction of the bracket 21 coincides with the symmetric centerline of the extension direction of the rack 14. In this way, the bracket 21 can be subjected to more balanced force during movement to prevent deviation, jamming or shaking.

[0073] like Figure 1 , Figure 3 as well as Figure 4 As shown, in some embodiments, the bracket 21 includes a first support portion 211 and a second support portion 212, the first support portion 211 and the second support portion 212 are movably connected, the first support portion 211 is movable along the thickness direction of the frame 10, the first support portion 211 is provided with a first massage portion 22, and the second support portion 212 is provided with a driving assembly 30 and a transmission assembly 40.

[0074] In this way, when the first sliding portion 2121 switches between the first track 131 and the second track 132, the relative position between the first support portion 211 and the frame 10 changes, which does not affect the engagement of the driving wheel 41 with the rack 14. The second support portion 212 and the first support portion 211 move relative to each other. In the thickness direction of the frame 10, the second support portion 212 remains unchanged relative to the frame 10, and the relative position of the driving wheel 41 and the rack 14 remains unchanged.

[0075] In some embodiments, one of the second support portion 212 and the first support portion 211 is provided with a first slide groove, the first slide groove extends along the thickness direction of the frame 10, and the other is provided with a guide column, which is movably clamped in the first slide groove. In this way, the first support portion 211 and the second support portion 212 are movably connected through the cooperation of the guide column and the first slide groove. When the first sliding portion 2121 switches between the first track 131 and the second track 132, the guide column moves in the first slide groove. The cooperation between the first slide groove and the guide column also guides the movement of the second support portion 212.

[0076] like Figure 1 and Figure 2 As shown, in some embodiments, the frame 10 is further provided with a second slide groove 15, and the second slide groove 15 is spaced apart from the first rail 131 and the second rail 132 in the thickness direction of the frame 10. The bracket 21 is further provided with a second sliding portion 2111 spaced apart from the first sliding portion 2121, and the second sliding portion 2111 is movably embedded in the second slide groove 15. When the first sliding portion 2121 switches between the first rail 131 and the second rail 132, the second sliding portion 2111 always moves in the second slide groove 15, so that the first support portion 211 is supported and limited by the cooperation of the second sliding portion 2111 and the second slide groove 15 to prevent shaking.

[0077] like Figure 8-Figure 10 As shown, in some embodiments, a third slide groove 16 is further provided on one side of the frame 10 close to the first massage part 22, and the first massage part 22 is opposite to the third slide groove 16, so that when the first sliding part 2121 switches between the first track 131 and the second track 132, the third slide groove 16 can avoid the first massage part 22 and provide sufficient retraction space for the first massage part 22.

[0078] In some embodiments, an energy emitting device is provided in the bracket 21 or the first massage part 22. The energy emitting device is used to emit a high-energy beam. The energy emitting device can move back and forth with the movement of the bracket 21. The high-energy beam emitted by the energy emitting device can act on the user's skin in a dispersed manner to prevent the high-energy beam from being concentrated at one point and causing burns to the user's skin or muscles.

[0079] The energy transmitting device is used to transmit high energy beams to the user. For example, the energy transmitting device can have ultrasonic transmitting function, infrared transmitting function, ultraviolet sterilization function, light wave transmitting function and micro current generating function.

[0080] Among them, ultrasonic beauty method utilizes the specific properties of mechanical ultrasonic vibration waves, which have high frequency and no interference, strong conductive penetration, and good directional energy transmission. It can perform precise and deep directional massage on various parts of the human body that need it. It can fully improve the permeability and activity of human tissues and blood circulation, dissolve and consume fat tissue, and at the same time soothe pores and make them transparent, so that they can expand to discharge dirt in the pores or introduce nutrients that are beneficial to skin absorption.

[0081] Infrared beauty therapy uses infrared light waves to irradiate parts of the human body or directly contact the human body through the working head to heat the skin. Infrared rays can act deeply on the human dermis tissue. Through the infrared thermal effect, it can dilate blood vessels to improve blood circulation, and make capillaries fully active to relieve fatigue, tighten the skin and remove wrinkles. It also has a certain effect on repairing skin scar damage.

[0082] Ultraviolet beauty therapy uses ultraviolet rays to act on the surface of the skin to kill bacteria. It can kill bacteria, remove dandruff, and improve skin acne spots.

[0083] Photon beauty therapy uses light waves to act on the skin to produce a strengthening effect.

[0084] Microcurrent beauty therapy uses medium-frequency pulse microcurrent to act on human muscles, nerves, skin and other tissues, stimulating human tissues to produce stress response impedance, thereby promoting skin metabolism and collagen fiber synthesis, playing a role in scar repair, wrinkle removal and muscle firming, stimulating human tissue nerves and improving human nerve fatigue.
