Description

Technical Field

[0001] This application relates to the field of beauty and skincare technology, specifically to a beauty instrument and a physiotherapy device. Background Technology

[0002] Beauty devices generally consist of a main unit and a treatment component. The treatment component is used to contact the skin to provide therapeutic effects. To facilitate adjustment of the relative angle and position between the treatment component and the main unit, some massage devices on the market use flexible wires to connect the treatment component to the main unit. During use, the treatment component can be detached from the main unit to provide therapeutic effects to the body.

[0003] However, in related technologies, in order to prevent the loss or damage of treatment components, beauty devices are generally equipped with storage boxes. When the treatment components are not in use, they are stored in the storage box. Before each use, the user needs to manually open the storage box to take out the treatment component. The operation of taking out the treatment component is relatively cumbersome and needs further improvement. Summary of the Invention

Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0052] Please refer to Figure 1 , Figure 2 and Figure 5 The beauty device 10 of this application includes a treatment component 1, a main unit 2, and a cable retracting mechanism 4. On the one hand, the main unit 2 is connected to the treatment component 1 via a connecting cable 3. The connection between the main unit 2 and the treatment component 1 is detachable. When in use, the treatment component 1 can be separated from the main unit 2. The user can hold the treatment component 1 and flexibly adjust the direction of force and the contact angle of the treatment component 1, thereby improving the flexibility of the treatment operation. In addition, compared to holding the entire beauty device 10, the user only needs to hold the lighter treatment component 1, which can effectively reduce hand fatigue. On the other hand, the winding mechanism 4 is fixed to the main unit 2. The winding mechanism 4 can automatically wind the connecting wire 3 into the storage compartment 21 without manual winding, which can save time and simplify the storage operation. In addition, the connecting wire 3 can be stored in the storage compartment 21 inside the main unit 2, which can improve the structural compactness of the beauty device 10, reduce the overall space occupied by the beauty device 10, and facilitate the carrying, storage and transportation of the beauty device 10. In addition, the connecting wire 3 can be stored in the storage compartment 21 inside the main unit 2, which can reduce the contamination of the connecting wire 3 by external dust, impurities and other pollutants. At the same time, at least part of the connecting wire 3 is hidden inside the main unit 2, making the overall appearance of the beauty device 10 more concise and beautiful.

[0053] In this embodiment, when the physiotherapy device 1 is placed on the host 2, at least part of the physiotherapy device 1 is exposed outside the host 2. The user can directly grab the exposed part of the physiotherapy device 1 with his / her hand to take out the physiotherapy device 1 for use, making it more convenient to grab the physiotherapy device 1.

[0054] In this embodiment, the main unit 2 has a handle housing 22 for the user to grip. When using the beauty device, the user can hold the handle housing 22. The storage compartment 21 is disposed in the handle housing 22. The outer side wall of the handle housing 22 is provided with a receiving groove 23 for accommodating the therapy component 1. The therapy component 1 is detachably connected to the receiving groove 23. When the therapy component 1 is disposed in the receiving groove 23, at least part of the therapy component 1 is exposed outside the receiving groove 23. The user can directly grab the therapy component 1 and pull it out for use, eliminating the step of manually opening the storage box. The operation of taking out the therapy component 1 is more convenient.

[0055] In this embodiment, the therapy device 1 is used for contact with the skin. The therapy device 1 may include one or more combinations of rollers, hot compress modules, cold compress modules, microcurrent electrodes, phototherapy modules, and vibration modules. When using the beauty device 10, the user can use it by holding the therapy device 1 to treat the skin of the user's lips, face, nose, or other areas.

[0056] In this embodiment, the therapeutic component 1 may include a roller. When in use, the roller can apply pressure to the skin through physical rolling, thereby expanding the gaps between the stratum corneum and promoting the transdermal absorption of active ingredients.

[0057] In this embodiment, the physiotherapy device 1 may include a heat therapy module. When in use, the heat therapy module can transfer heat to the skin to promote the absorption of active ingredients through the skin.

[0058] In this embodiment, the physiotherapy device 1 may include a cold compress module. When the surface of the cold compress module comes into contact with the skin, the epidermal temperature is lowered through direct heat conduction, thereby achieving a physiotherapy effect.

[0059] In this embodiment, the physiotherapy device 1 may include a microcurrent electrode, which can emit a microcurrent to stimulate the skin, thereby achieving a physiotherapy effect.

[0060] In this embodiment, the physiotherapy device 1 may include a phototherapy module. When in use, the light emitted by the phototherapy module can be used to irradiate the skin to achieve a phototherapy effect.

[0061] In this embodiment, the physiotherapy device 1 may include a vibration module, which can gently stimulate the skin while applying skin care products, thereby accelerating the penetration and absorption of the skin care products and improving the skin care effect.

[0062] In this embodiment, the physiotherapy device 1 may include an iontophoresis electrode. When in use, the iontophoresis electrode can establish a direct current electric field on the skin, and the direct current will pass through the skin to achieve the physiotherapy effect.

[0063] In one embodiment, the connecting line 3 can be a conductive wire with conductive function, and the host 2 can be electrically connected to the physiotherapy device 1 through the connecting line 3. For example, the physiotherapy device 1 is provided with a third circuit board, and the host 2 is provided with a main circuit board 24, and the connecting line 3 is electrically connected to the third circuit board and the main circuit board 24 respectively.

[0064] In one embodiment, the beauty device further includes a wireless communication module (e.g., Bluetooth or Wi-Fi), through which the host 2 can connect to the therapy device 1. For example, the wireless communication module includes a first wireless communication module and a second wireless communication module. The first wireless communication module is disposed in the host 2 and electrically connected to the main circuit board 24 in the host 2. The therapy device 1 is provided with a third circuit board and a second wireless communication module, which are electrically connected, and the first and second wireless communication modules are connected by a signal. The host 2 can control the operation of the therapy device 1 through the wireless communication module.

[0065] In one embodiment, reference Figure 12 and Figure 13 The physiotherapy device 1 includes a gripping part 11 and multiple physiotherapy modules. The physiotherapy functions of the multiple physiotherapy modules are different from each other. Each physiotherapy module is detachably connected to the gripping part 11, allowing users to easily replace physiotherapy modules with different physiotherapy functions according to their own needs. The replacement of physiotherapy modules is simple and convenient. The physiotherapy functions may include, but are not limited to, roller physiotherapy, hot compress physiotherapy, cold compress physiotherapy, microcurrent stimulation physiotherapy, phototherapy, vibration physiotherapy, iontophoresis physiotherapy, etc. For example, the physiotherapy device 1 includes a gripping part 11, a first physiotherapy module and a second physiotherapy module. The gripping part 11 is provided with a first magnet 113, a third circuit board 114 and two conductive terminals 115. The third circuit board 114 is electrically connected to the connecting line 3 and the conductive terminals 115 respectively. The two conductive terminals 115 are disposed on one end of the gripping part 11. The first physiotherapy module includes a first base 13, two microcurrent electrodes 14, and a second magnet 15. The two microcurrent electrodes 14 are fixed to one end of the first base 13, and the second magnet 15 is fixed to the other end of the first base 13. The first physiotherapy module is magnetically fixed to the grip portion 11 by the first magnet 113 and the second magnet 15. When the first physiotherapy module is fixed to the grip portion 11, the two conductive terminals 115 can be electrically connected to the two microcurrent electrodes 14 respectively, and the two microcurrent electrodes 14 can output microcurrents to the skin. The second physiotherapy module includes a second base 16, two rollers 17, and a third magnet 18. The two rollers 17 are rotatably connected to one end of the second base 16, and the third magnet 18 is fixed to the other end of the second base 16. The second physiotherapy module is magnetically fixed to the grip portion 11 by the first magnet 113 and the third magnet 18. In use, the rollers 17 can apply pressure to the skin through physical rolling, widening the gaps between the stratum corneum and promoting the transdermal absorption of active ingredients.

[0066] In other embodiments, each physiotherapy module may be detachably connected to the gripping part 11 by means of snap-fit ​​connection, screw connection, threaded connection, etc., which is not limited here.

[0067] In one embodiment, the beauty device further includes a skin detection sensor (not shown in the figure), which is electrically connected to the main circuit board 24 of the host 2. The skin detection sensor can be mounted on the host 2 or on the treatment device 1. The skin detection sensor can detect skin parameters such as hydration, temperature, oil content, sun protection factor, or impedance, and send feedback signals to the main circuit board 24. The main circuit board 24 is used to control the display screen assembly 29 to display the detection results fed back by the skin detection sensor. The user can select a treatment device 1 with specific treatment functions for treatment based on the detection results. When the beauty device includes multiple treatment devices 1, the skin detection sensor can be mounted on one of the treatment devices 1, or it can be mounted on each treatment device 1; this is not limited here.

[0068] In this embodiment, the connection method between the winding mechanism 4 and the main unit 2 is not limited. The winding mechanism 4 can be fixed to the main unit 2 by adhesive bonding, snap-fit ​​connection, screw connection or other connection methods. The fixed position of the winding mechanism 4 in the main unit 2 is also not limited. For example, the winding mechanism 4 can be fixed in the receiving compartment 21 of the main unit 2; or, for example, the winding mechanism 4 can be fixed on the outer wall of the handle housing 22 of the main unit 2.

[0069] In this embodiment, it should be noted that when using the beauty device 10, the therapy component 1 can be separated from the main unit 2 and electrically connected to the main unit 2 through the connecting cable 3. The main unit 2 and the therapy component 1 can be detachably connected. The cable winding mechanism 4 can retract the entire section of the connecting cable 3 that is stretched out of the main unit 2 into the receiving chamber 21. Alternatively, the cable winding mechanism 4 can retract only a portion of the section of the connecting cable 3 that is stretched out of the main unit 2 into the receiving chamber 21. This is not limited here.

[0070] In one embodiment, the connecting line 3 can be a conductive wire with conductive function, and the host 2 can be electrically connected to the physiotherapy device 1 through the connecting line 3. For example, the physiotherapy device 1 is provided with a third circuit board, and the host 2 is provided with a main circuit board 24, and the connecting line 3 is electrically connected to the third circuit board and the main circuit board 24 respectively.

[0071] In one embodiment, the beauty device further includes a wireless communication module (e.g., Bluetooth or Wi-Fi), through which the main unit can establish a signal connection with the therapy device 1. For example, the wireless communication module includes a first wireless communication module and a second wireless communication module. The first wireless communication module is disposed in the main unit 2 and electrically connected to the main circuit board 24 in the main unit 2. The therapy device 1 is provided with a third circuit board and a second wireless communication module, which are electrically connected, and the first and second wireless communication modules are signal-connected. The main unit 2 can control the operation of the therapy device 1 through the wireless communication module.

[0072] In one embodiment, reference Figure 2 , Figure 4 and Figure 5 The receiving slot 23 is connected to the receiving chamber 21. One end of the connecting wire 3 is fixedly connected to the wire take-up mechanism 4, and the other end is fixedly connected to the physiotherapy component 1. When the wire take-up mechanism 4 automatically winds the connecting wire 3 into the receiving chamber 21, the connecting wire 3 can drive the physiotherapy component 1 to move, so that the physiotherapy component 1 moves into the receiving slot 23. In this embodiment, when the wire take-up mechanism 4 retracts the connecting wire 3, it directly drives the physiotherapy component 1 into the receiving slot 23 of the outer shell, eliminating the need for the user to manually place the physiotherapy component 1, thus achieving automatic retrieval of the physiotherapy component 1 and reducing the risk of loss. In addition, at least part of the physiotherapy component 1 is stored in the receiving slot 23, which makes the overall appearance of the machine simpler.

[0073] In one embodiment, reference Figure 2 and Figure 4 The receiving groove 23 includes a first groove wall 232 and a second groove wall 233 connected to each other. At least a portion of the outer side wall of the handle housing 22 forms the first groove wall 232. The second groove wall 233 surrounds the outer periphery of the first groove wall 232. The second groove wall 233 has an opening at one end away from the first groove wall 232. The physiotherapy component 1 can enter or leave the receiving groove 23 through the opening. The physiotherapy component 1 can be received in the receiving groove 23 on the outer side wall of the handle housing 22, which makes it convenient for the user to directly take the physiotherapy component 1 from the outer side wall of the handle housing 22 for use.

[0074] The therapeutic device 1 includes a gripping part 11 and a conductive electrode 12. The gripping part 11 provides a gripping space for the user. The conductive electrode 12 is fixed to one end of the gripping part 11 and protrudes from the gripping part 11 to contact the skin. A connecting wire 3 is electrically connected to the conductive electrode 12, and an electric current is applied to the skin surface through the conductive electrode 12. Specifically, when the conductive electrode 12 is used as a microcurrent electrode, it can apply alternating current to the skin surface to stimulate skin cells; when the conductive electrode 12 is used as an iontophoresis electrode, it can apply direct current to the skin. The direct current can penetrate the skin barrier and deliver specific components to the target tissue.

[0075] refer to Figure 11 When the therapy device 1 is placed in the receiving slot 23, at least a portion of the conductive electrode 12 protrudes from the main unit 2 through the opening. When the user grips the handle housing 22, their hand can directly contact the exposed conductive electrode 12 without removing the therapy device 1 from the receiving slot 23, facilitating the formation of a current circuit between the skin and the conductive electrode 12. In one embodiment, refer to... Figure 2 and Figure 4 The first groove wall 232 includes a protrusion 2321 and a concave portion 2322 connected in sequence. The concave portion 2322 is recessed inward relative to the protrusion 2321. When the physiotherapy component 1 is fixed in the receiving groove 23, the conductive electrode 12 and the concave portion 2322 are arranged face to face and spaced apart. The second groove wall 233 is spaced apart from the conductive electrode 12. Because the connecting line has a certain length, the winding trajectory of the connecting line 3 is unstable when the connecting line 3 is automatically wound up, and the physiotherapy piece 1 swings with the movement of the connecting line 3; the conductive electrode 12 is spaced apart from the concave portion 2322, and the second groove wall 233 is spaced apart from the physiotherapy piece 1. The receiving groove 23 has a swing margin for the physiotherapy piece 1 in both the diameter direction and the depth direction. When the conductive electrode 12 enters the receiving groove 23, it is not easy to hit the first groove wall 232 and the second groove wall 233, which can reduce the risk of damage to the conductive electrode 12 or poor electrical contact caused by collision.

[0076] In one embodiment, reference Figure 2 and Figure 4 The take-up mechanism 4 is located in the receiving chamber 21. The first groove wall 232 is provided with a wire-passing hole 231, which is connected to the receiving chamber 21. One end of the connecting wire 3 is fixedly connected to the take-up mechanism 4, and the other end passes through the wire-passing hole 231 and is fixedly connected to the conductive electrode 12. The connecting wire 3 can pass through the wire-passing hole 231, but the physiotherapy device 1 cannot pass through the wire-passing hole 231. When the take-up mechanism 4 retracts the connecting wire 3, it can drive the physiotherapy device 1 into the receiving groove 23 of the outer shell. The first groove wall 232 of the receiving groove 23 can block the receiving groove 23 and the receiving chamber 21, so that the physiotherapy device 1 will not be pulled into the receiving chamber 21. The physiotherapy device 1 can be accommodated in the receiving groove 23 on the outer side wall of the handle outer shell 22, which makes it convenient for the user to directly take out the physiotherapy device 1 from the outer side wall of the handle outer shell 22 for use.

[0077] In this embodiment, the edge of the wire hole 231 is provided with an arc-shaped transition surface, which can reduce the friction between the edge of the wire hole 231 and the connecting wire 3, so that the connecting wire 3 can be pulled out or retracted more smoothly.

[0078] In this embodiment, the second groove wall 233 includes a first enclosure wall 2331 and a second enclosure wall 2332 connected to each other. The first enclosure wall 2331 is disposed at the edge of the protrusion 2321, and the second enclosure wall 2332 is disposed at the edge of the concave portion. The second enclosure wall 2332 is an arc-shaped wall, and the height of the second enclosure wall 2332 gradually decreases in the direction away from the protrusion 2321. The gradually decreasing height of the second enclosure 2332 forms a "guide ramp," allowing the therapeutic component 1 to slide into the receiving groove 23 along the second enclosure 2332, making it easier for the therapeutic component 1 to enter the receiving groove 23. In addition, the height of the second enclosure 2332 gradually decreases in the direction away from the protrusion 2321, which can reduce the obstruction of the second enclosure 2332 on the therapeutic component 1. Even if the therapeutic component 1 has a slight collision with the second enclosure 2332, the small contact area reduces the risk of damage to the therapeutic component 1. At the same time, when the therapeutic component 1 is installed in the receiving groove 23, the second enclosure 2332 will cover the conductive electrode 12 less, and the conductive electrode 12 will have a larger exposed area. When the user holds the handle shell with one hand, it is easier for the hand to contact the conductive electrode 12.

[0079] In this embodiment, the height of the second enclosure 2332 refers to the distance between the end of the second enclosure 2332 and the reference plane in the radial direction of the handle housing, with the plane where the recess 2321 is located as the reference plane.

The fixed base 41 is limitedly connected to the receiving chamber 21 to prevent the fixed base 41 from rotating relative to the receiving chamber 21. For example, the outer wall of the fixed base 41 is provided with a groove, and the inner wall of the receiving chamber 21 is provided with a protrusion. The protrusion is inserted into the groove to prevent the fixed base 41 from rotating relative to the receiving chamber 21. Alternatively, the fixed base 41 may be directly bonded to the inner wall of the receiving chamber 21.

[0084] In this embodiment, the winding assembly 42 is disposed in the receiving chamber 21. One end of the connecting wire 3 is fixed to the winding assembly 42, and the other end is fixedly connected to the physiotherapy component 1. The winding assembly 42 can rotate relative to the fixed base 41 in a first direction, so that the connecting wire 3 is wound around the winding assembly 42, thereby realizing the function of winding the connecting wire 3 into the receiving chamber 21. In addition, the winding assembly 42 can rotate relative to the fixed base 41 in a second direction, so as to release the connecting wire 3 on the winding assembly 42, thereby realizing the function of releasing the connecting wire 3. The rotation direction of the first direction is opposite to the rotation direction of the second direction. For example, the first direction can be clockwise and the second direction can be counterclockwise; or, the first direction can be counterclockwise and the second direction can be clockwise.

[0085] In one specific embodiment, reference is made to Figure 6The winding assembly 42 includes a drum 421, which includes a body 4211 and a limiting plate 4212. The limiting plate 4212 is fixed to one end of the body 4211. The middle part of the drum 421 has a shaft hole 4213 that passes through the body 4211 and the limiting plate 4212. The fixing seat 41 includes a base plate 411 and a post 412. The post 412 extends into the shaft hole 4213 so that the drum 421 can rotate around the post 412. The limiting plate 4212 and the base plate 411 are located at opposite ends of the body 4211. The limiting plate 4212, the base plate 411 and the body 4211 form a winding cavity for storing the connecting wire 3. The connecting wire 3 can be wound around the outer circumference of the body 4211. The take-up mechanism 4 also includes a coil spring, which is sleeved on the outer periphery of the insert post 412. One end of the coil spring is fixedly connected to the insert post 412, and the other end is fixedly connected to the cylinder 4211 of the drum 421. For example, the coil spring can be fixedly connected to the insert post 412 and the cylinder 4211 by welding, bonding or other means. The fixed base 41 is provided with a first outlet 413 communicating with the take-up cavity. The cavity wall of the receiving chamber 21 is provided with a second outlet 211 communicating with the first outlet 413 and the through hole 231. One end of the connecting wire 3 is fixed to the cylinder 4211, and the other end passes through the first outlet 413, the second outlet 211 and the through hole 231 in sequence and is fixedly connected to the physiotherapy piece 1. When the physiotherapy piece 1 or the connecting wire 3 is pulled outward, the connecting wire 3 can drive the cylinder 4211 to rotate relative to the insert post 412 in the second direction to release the connecting wire 3 on the cylinder 4211. When the cylinder 4211 rotates relative to the insert post 412 in the second direction, it can cause the elastic element 44 to undergo elastic deformation. When the external force on the physiotherapy piece 1 and / or the connecting wire 3 is removed, the cylinder 4211 can rotate relative to the insert post 412 in the first direction under the reset force of the elastic element 44, so that the connecting wire 3 automatically winds around the cylinder 4211.

[0086] In another embodiment, the winding assembly 42 includes a drum 421, which includes a body 4211 and a limiting plate 4212. The limiting plate 4212 is fixed to one end of the body. The drum 421 has a shaft hole 4213 in the middle that passes through the body 4211 and the limiting plate 4212. The fixing base 41 includes a base plate 411 and a post 412. The post 412 extends into the shaft hole 4213 so that the drum 421 can rotate around the post 412. The limiting plate 4212 and the base plate 411 are located at opposite ends of the body 4211. The limiting plate 4212, the base plate 411 and the body 4211 form a winding cavity for storing the connecting wire 3. The connecting wire 3 can be wound around the outer circumferential surface of the body 4211. The fixed base 41 is provided with a first outlet 413 communicating with the take-up cavity. The cavity wall of the receiving chamber 21 is provided with a second outlet 211 communicating with the first outlet 413 and the through hole 231. One end of the connecting wire 3 is fixed to the cylinder 4211, and the other end passes through the first outlet 413, the second outlet 211 and the through hole 231 in sequence and is fixedly connected to the physiotherapy component 1. The take-up mechanism 4 also includes a drive motor (not shown in the figure). The drive motor has an output shaft, which is fixedly connected to the cylinder 4211. The drive motor can drive the output shaft to rotate in a second direction. When the output shaft rotates, it can drive the cylinder 4211 to rotate in the second direction relative to the insert 412 to release the connecting wire 3 on the cylinder 4211. The drive motor can also drive the output shaft to rotate in a first direction. When the output shaft rotates, it can drive the cylinder 4211 to rotate in the first direction relative to the insert 412 so that the connecting wire 3 is automatically wound around the cylinder 4211.

[0087] In one embodiment, reference Figure 6 The take-up mechanism 4 also includes an elastic element 44, one end of which is fixedly connected to the fixed base 41, and the other end is fixedly connected to the take-up assembly 42. When the therapeutic component 1 and / or the connecting wire 3 are subjected to tension, the connecting wire 3 can drive the take-up assembly 42 to rotate relative to the fixed base 41 in a second direction to release the connecting wire 3 on the take-up assembly 42. When the take-up assembly 42 rotates in the second direction, the elastic element 44 can undergo elastic deformation. When the external force on the therapeutic component 1 and / or the connecting wire 3 is removed, the take-up assembly 42 can rotate relative to the fixed base 41 in a first direction under the reset force of the elastic element 44, so that the connecting wire 3 automatically winds around the take-up assembly 42. In this embodiment, the reset force of the elastic element 44 is used to drive the take-up assembly 42 to rotate relative to the fixed base 41 in the first direction, eliminating the need for an additional power source, reducing the number of parts, simplifying the structure, and saving costs.

[0088] In this embodiment, the type of elastic element 44 is not limited, and elastic element 44 may include at least one of spring, coil spring, etc.

[0089] In one embodiment, reference Figure 6The winding assembly 42 includes a drum 421 and a first circuit board 422. The first circuit board 422 is fixedly connected to the drum 421, and the drum 421 is rotatably connected to the mounting base 41. One end of the connecting wire 3 is fixed to the drum 421, and the connecting wire 3 is electrically connected to the first circuit board 422. The first circuit board 422 is provided with an elastic electrode 4221. The winding mechanism 4 also includes a second circuit board 45, which is fixed to the mounting base 41 and abuts against the elastic electrode 4221. The first circuit board 422 is electrically connected to the second circuit board 45 through the elastic electrode 4221. When the drum 421 rotates, the connecting wire 3 fixed to one end of the drum 421 and the first circuit board 422 rotate synchronously, which can improve the stability of the electrical connection between the connecting wire 3 and the first circuit board 422. The first circuit board 422 is provided with an elastic electrode 4221, and the second circuit board 45 abuts against the elastic electrode 4221. The first circuit board 422 is electrically connected to the second circuit board 45 through the elastic electrode 4221. The electrical connection between the two circuit boards does not depend on conductive wires, which can reduce the risk of conductive wires becoming entangled when the first circuit board 422 rotates relative to the second circuit board 45. At the same time, it can ensure that the elastic electrode 4221 and the second circuit board 45 always maintain an electrical connection. In this embodiment, the elastic electrode 4221 may include one or more of the following: a spring pin, an elastic electrode sheet.

[0090] In one embodiment, reference Figure 2 , Figure 6 and Figure 7 The main unit 2 also includes a main circuit board 24 and a battery 25 electrically connected. The battery 25 can supply power to the main circuit board 24. The main circuit board 24 and the second circuit board 45 are electrically connected. There are two conductive electrodes 12, which are spaced apart. The conductive electrodes 12 can be made of conductive metal materials such as stainless steel or silver. The grip part 11 can be made of electrically insulating materials such as plastic or silicone. During operation, the main circuit board 24, the second circuit board 45, the first circuit board 422, the connecting wire 3, and the conductive electrodes 12 can be connected to form a current circuit. The current circuit is configured to form a current loop when the two conductive electrodes 12 come into contact with the skin. Alternatively, there can be one conductive electrode 12. Both the conductive electrode 12 and the grip part 11 can be made of conductive metal materials such as stainless steel or silver. During operation, the grip part 11, the main circuit board 24, the second circuit board 45, the first circuit board 422, the connecting wire 3, and the conductive electrode 12 can be connected to form a current circuit. The current circuit is configured to form a current loop when the human hand grips the grip part 11 and the conductive electrode 12 comes into contact with the skin.

[0091] In one embodiment, reference Figure 2The device comprises multiple therapeutic elements 1, connecting wires 3, receiving slots 23, and wire winding mechanisms 4. The conductive electrodes of each therapeutic element 1 are electrically connected to the main unit 2 via corresponding connecting wires 3. Each receiving slot 23 can accommodate a corresponding therapeutic element 1, and each wire winding mechanism 4 can automatically wind the corresponding connecting wire 3 into the receiving chamber 21. In this embodiment, multiple therapeutic elements 1 can simultaneously act on different areas (such as the shoulders and neck, waist, and legs), reducing the inconvenience of repeatedly moving a single therapeutic element 1. In addition, each conductive electrode 12 is exposed outside the main unit 2 through an opening. When the user is receiving treatment, one hand pulls out one of the treatment components 1 and makes the treatment component 1 contact the target skin area, while the other hand holds the handle housing 22 and directly contacts the conductive electrode 12 of the other treatment component 1 in the receiving slot 23. This allows the human hand, the first conductive electrode 12, the first connecting line 3, the main unit 1, the second connecting line 3, the second conductive electrode 12 and the target skin to form a current loop. The user can carry and move the beauty device 10 with them when receiving treatment, making the use of the beauty device 10 more flexible and convenient.

[0092] In one specific embodiment, reference is made to Figure 2 The number of therapeutic components 1, connecting wires 3, and take-up mechanisms 4 are all two. During operation, the first conductive electrode 12, the first connecting wire 3, the first first circuit board 422, the first second circuit board 45, the main circuit board 24, the second second circuit board 45, the second first circuit board 422, the second connecting wire 3, and the second conductive electrode 12 can be connected to form a current circuit. The current circuit is configured to form a current loop when the two conductive electrodes 12 come into contact with the skin.

[0093] In one embodiment, reference Figure 4The receiving chamber 21 includes an upper side wall 212, a lower side wall 213, and a limiting wall 214. The upper side wall 212 and the lower side wall 213 are arranged opposite each other at both ends of the limiting wall 214 along the axial direction of the receiving chamber 21. The upper side wall 212, the lower side wall 213, and the limiting wall 214 together enclose a receiving space in which multiple take-up mechanisms 4 are located. The multiple take-up mechanisms 4 are stacked along the axial direction of the receiving chamber 21, and the multiple take-up mechanisms 4 are sandwiched between the upper side wall 212 and the lower side wall 213. This can make full use of the axial space of the receiving chamber 21 and reduce the increase in the volume of the receiving chamber 21 caused by radial expansion. At the same time, the upper side wall 212 and the lower side wall 213 press the take-up mechanism 4 along the axial direction. There is no need to set a partition between the multiple take-up mechanisms 4, which can further reduce the volume of the receiving chamber 21 and reduce the axial shaking of the take-up mechanism 4 when the beauty device 10 moves. Furthermore, the cross-sectional shape of the take-up mechanism 4 is adapted to the cross-sectional shape of the limiting wall 214. The cross-sectional shape of the limiting wall 214 is polygonal, and the cross-section is perpendicular to the axis of the receiving chamber 21. The inner wall of the polygonal limiting wall 214 has multiple sharp corners or straight edges, which can directly limit the accidental rotation of the take-up mechanism 4 through physical blocking of the corners. Moreover, the polygonal adaptation structure locks the take-up mechanism 4 through shape matching, eliminating the need for additional screws, buckles and other locking components. This reduces the space occupied by screws, buckles and other locking components, further reducing the volume of the receiving chamber 21 and facilitating the miniaturization of the beauty device 10.

[0094] In this embodiment, the cross-sectional shape of the limiting wall 214 can be triangular, quadrilateral, pentagonal, hexagonal, etc., and is not limited here.

[0095] In one embodiment, reference Figure 7 The beauty device 10 also includes a current adjustment module 26 and a time adjustment module 27. The main circuit board 24 is electrically connected to the current adjustment module 26 and the time adjustment module 27 respectively. The current adjustment module 26 is used to adjust the magnitude of the current output by the conductive electrode 12, and the time adjustment module 27 is used to adjust the duration of the current output by the conductive electrode 12.

[0096] In this embodiment, by setting multiple sets of therapeutic components 1, connecting lines 3, receiving slots 23, and wire take-up mechanisms 4, the beauty device offers users a variety of usage options. Users can place the main unit 2 on a table and hold two therapeutic components with both hands to apply treatment to the target skin area; alternatively, users can hold the main unit 2 with one hand and the therapeutic component 1 with the other hand to apply treatment to the target skin area.

[0097] In one embodiment, reference Figure 7The beauty device 10 also includes a charging electrode assembly 28 and a display screen assembly 29. The main circuit board 24 is electrically connected to the charging electrode assembly 28 and the display screen assembly 29 respectively. The charging electrode assembly 28 is electrically connected to the battery 25, and an external power source can charge the battery 25 through the charging electrode assembly 28. The display screen is fixed to the housing of the main unit 2 and is used to display parameters such as the magnitude and duration of the current output by the conductive electrode 12.

[0098] In one embodiment, reference Figure 8 The beauty device 10 also includes a locking member 5, which is disposed on the fixed base 41 and / or the main unit 2. The locking member 5 can prevent the winding assembly 42 from rotating relative to the fixed base 41 in the first direction, so that the connecting wire 3 maintains a preset pulled-out length. After the user pulls out the connecting wire 3 to the required length according to the treatment area, the user can fix the winding assembly 42 by locking the locking member 5 to prevent the winding mechanism 4 from automatically retracting the connecting wire 3 and interfering with the treatment operation.

[0099] In one specific embodiment, the winding assembly 42 includes a drum 421, which includes a body 4211 and a limiting plate 4212. The limiting plate 4212 is fixed to one end of the body. The drum 421 has a shaft hole 4213 in the middle that passes through the body 4211 and the limiting plate 4212. The fixing base 41 includes a base plate 411 and a post 412. The post 412 extends into the shaft hole 4213 so that the drum 421 can rotate around the post 412. The limiting plate 4212 and the base plate 411 are located at opposite ends of the body 4211. The limiting plate 4212, the base plate 411 and the body 4211 form a winding cavity for storing the connecting wire 3. The connecting wire 3 can be wound around the outer circumferential surface of the body 4211. The take-up mechanism 4 also includes a coil spring, which is sleeved on the outer periphery of the insert post 412. One end of the coil spring is fixedly connected to the insert post 412, and the other end is fixedly connected to the drum body 4211 of the drum 421. The fixed base 41 is provided with a first outlet 413 communicating with the take-up cavity. The cavity wall of the receiving chamber 21 is provided with a second outlet 211 communicating with the first outlet 413 and the through hole 231. One end of the connecting wire 3 is fixed to the cylinder 4211, and the other end passes through the first outlet 413, the second outlet 211 and the through hole 231 in sequence and is fixedly connected to the physiotherapy piece 1. When the physiotherapy piece 1 or the connecting wire 3 is pulled outward, the connecting wire 3 can drive the cylinder 4211 to rotate relative to the insert post 412 in the second direction to release the connecting wire 3 on the cylinder 4211. When the cylinder 4211 rotates relative to the insert post 412 in the second direction, it can cause the elastic element 44 to undergo elastic deformation. When the external force on the physiotherapy piece 1 and / or the connecting wire 3 is removed, the cylinder 4211 can rotate relative to the insert post 412 in the first direction under the reset force of the elastic element 44, so that the connecting wire 3 automatically winds around the cylinder 4211. The locking component 5 includes an electromagnetic linear actuator (not shown in the figure). The electromagnetic linear actuator is fixed at the first outlet 413. The handle housing 22 of the main unit 2 is provided with a button to control the operation of the electromagnetic linear actuator. When the user pulls out the connecting line 3 to the required length, the electromagnetic linear actuator can be controlled to work by pressing the button, so that the guide shaft of the electromagnetic linear actuator extends into the first outlet 413 and presses against the cylinder 4211 to prevent the cylinder 4211 from continuing to rotate relative to the insert 412, thereby keeping the connecting line 3 at the preset pull-out length.

[0100] In another specific embodiment, refer to Figure 8A limiting ring groove 4214 is formed on the side of the limiting plate 4212 away from the base plate 411. The locking member 5 is a ball that cooperates with the limiting ring groove 4214. The ball can roll along the limiting ring groove 4214. The take-up mechanism 4 also includes a cover 43, which is fixedly connected to the fixed base 41. The limiting plate 4212 is located between the cover 43 and the cylinder 4211. The cover 43 is provided with a guide groove 431 for guiding the ball along the radial direction of the limiting plate 4212. The guide groove 431 communicates with the limiting ring groove 4214. One end of the ball is located in the guide groove 431, and the other end is located in the limiting ring groove 4214. The limiting ring groove 4214 includes a running section and a reset section. The running section is the movement trajectory of the ball when the connecting line 3 is unwound normally; the reset section is the movement trajectory of the ball when the connecting line 3 resumes automatic take-up. The running section includes multiple arc-shaped grooves 4311, and guide protrusions 4312 are provided in the arc-shaped grooves 4311. The guide protrusions 4312 can guide the movement direction of the balls.

[0101] When connecting line 3 is pulled out, the ball moves forward within the running section. Figure 9 (In the direction of the arrow in the image) After the connecting line 3 is pulled out to the required length, the connecting line 3 is released. Under the reset force of the coil spring, the ball moves in the opposite direction within the running section to the adjacent guide protrusion 4312. The guide protrusion 4312 prevents the ball from continuing to move in the opposite direction within the running section, thereby preventing the drum 421 from continuing to rotate in the opposite direction, thus locking the connecting line 3 so that the pulled-out connecting line 3 can remain in the pulled-out state for user use.

[0102] When connecting wire 3 is finished being used and needs to be wound up, pull connecting wire 3 outward to move the ball to the end of the running section, then release connecting wire 3, and the ball enters the reset section from the running section. Guided by guide protrusion 4312, the ball moves in the opposite direction along the reset section. Figure 10 (In the direction of the arrow in the text) to the starting point of the running section, so that the connecting line 3 can be automatically wound up under the reset force of the coil spring.

[0103] In this embodiment, the length of the connecting line 3 is 0.4 meters to 1 meter. If the connecting line 3 is too long, it will easily increase the risk of knotting and tangling, and at the same time, it will increase the overall size and weight of the beauty device 10. If the connecting line 3 is too short, it will easily reduce the radius of motion of the therapy component 1 and reduce the operational flexibility of the therapy component 1. Optionally, the length of the connecting line can be any one or any two of 0.4 meters, 0.5 meters, 0.6 meters, 0.7 meters, 0.8 meters, 0.9 meters, and 1 meter, and is not limited here.

[0104] This application also provides a physiotherapy device 100, which includes a container 20 and a beauty device 10 as described above. The container 20 is fixedly connected to the beauty device 10 and is used to store skincare products. The beauty device 10 and the container 20 are assembled together, making it convenient for users to directly take out the physiotherapy device 10 to treat their skin after using skincare products, thereby promoting the absorption of the skincare products and avoiding the need for users to separately search for the beauty device 10. Furthermore, the beauty device 10 can be carried along with the skincare products, improving ease of use.

[0105] In this embodiment, the method of fixing the container 20 to the beauty device 10 is not limited. For example, the inner wall surface of one end of the handle housing 22 of the main unit 2 has an internal thread, and the outer wall surface of the container 20 has an external thread that mates with the internal thread, so the container 20 is threadedly connected to one end of the handle housing 22. As another example, the inner wall surface of one end of the handle housing 22 of the main unit 2 has a buckle, and the outer wall surface of the container 20 has a groove that mates with the buckle, so the container 20 is snapped together with one end of the handle housing 22.

[0106] The embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
