Description

Technical Field

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

[0002] A physiotherapy device typically consists of a main unit and a massage head. The massage head is used to contact the skin to provide therapeutic effects. To facilitate adjustment of the relative angle and position between the massage head and the main unit, some massage devices on the market use flexible wires to connect the massage head to the main unit, allowing the massage head to be removed from the main unit during use.

[0003] However, in the relevant technologies, after each use of the physiotherapy device, it takes a long time to manually tidy up the power cord, which is a rather cumbersome process and needs further improvement. Utility Model Content

[0004] The embodiments of this application provide a physiotherapy device and apparatus that can solve the technical problem of cumbersome wire storage operations.

[0005] In a first aspect, embodiments of this application provide a physiotherapy device, comprising:

[0006] Massage heads are used to contact the skin for physical therapy.

[0007] The main unit is connected to the massage head via a connecting cable. The massage head and the main unit are detachably connected. The main unit has a compartment inside for accommodating the connecting cable.

[0008] A winding mechanism, fixed to the host, is capable of automatically winding the connecting wire into the receiving compartment.

[0009] In one embodiment, the main unit has a housing, the receiving compartment is disposed in the housing, and an accommodating groove for accommodating the massage head is formed on the outer side wall of the housing, the accommodating groove communicating with the receiving compartment;

[0010] One end of the connecting line is fixedly connected to the winding mechanism, and the other end is fixedly connected to the massage head. When the winding mechanism automatically winds the connecting line into the receiving chamber, the connecting line can drive the massage head to move so that the massage head moves into the receiving slot.

[0011] In one embodiment, the winding mechanism is located in the receiving chamber, and a cable passage hole communicating with the receiving chamber is provided on the wall of the receiving groove. One end of the connecting cable is fixedly connected to the winding mechanism, and the other end passes through the cable passage hole and is fixedly connected to the massage head; and / or

[0012] The physiotherapy device also includes fasteners, through which the massage head is detachably fixed in the receiving groove.

[0013] In one embodiment, the massage head includes a handle and conductive electrodes fixedly connected together, at least a portion of the conductive electrodes protruding from the handle to contact the skin, and the connecting wire being electrically connected to the conductive electrodes;

[0014] The receiving groove includes a bottom wall and a side wall connected to each other. The side wall surrounds the outer periphery of the bottom wall. The bottom wall includes a first bottom wall and a second bottom wall connected in sequence. The second bottom wall is recessed inward relative to the first bottom wall. When the massage head is fixed in the receiving groove, the conductive electrode is arranged face to face with the second bottom wall, and the conductive electrode is spaced apart from the second bottom wall.

[0015] In one embodiment, the sidewall includes a first sidewall and a second sidewall connected to each other. The first sidewall is disposed at the edge of the first bottom wall, and the second sidewall is disposed at the edge of the second bottom wall. The second sidewall is an arc-shaped sidewall, and the height of the second sidewall gradually decreases in the direction away from the first bottom wall.

[0017] A fixed base is connected to the receiving compartment to limit its rotation relative to the receiving compartment;

[0018] A winding assembly is disposed in the receiving chamber, and one end of the connecting line is fixed to the winding assembly, while the other end is fixedly connected to the massage head;

[0019] The winding assembly is rotatable relative to the fixed base in a first direction to wind the connecting wire onto the winding assembly, and the winding assembly is rotatable relative to the fixed base in a second direction to release the connecting wire from the winding assembly.

[0020] The rotation direction in the first direction is opposite to the rotation direction in the second direction.

[0021] In one embodiment, the winding mechanism further includes an elastic element, one end of which is fixedly connected to the fixed base and the other end of which is fixedly connected to the winding assembly;

[0022] When the massage head and / or the connecting line is subjected to tension, the connecting line can drive the winding assembly to rotate relative to the fixed base in the second direction to release the connecting line on the winding assembly. When the winding assembly rotates in the second direction, it can cause the elastic element to undergo elastic deformation.

[0023] When the external force on the massage head and / or the connecting line is removed, the winding assembly can rotate relative to the fixed base in the first direction under the restoring force of the elastic element, so that the connecting line is wound around the winding assembly.

[0024] In one embodiment, the winding assembly includes a drum and a first circuit board, the first circuit board being fixedly connected to the drum, the drum being rotatably connected to the fixed base, one end of a connecting wire being fixed to the drum, and the connecting wire being electrically connected to the first circuit board, the first circuit board being provided with an elastic electrode; the winding mechanism further includes a second circuit board, the second circuit board being fixed to the fixed base, the second circuit board abutting against the elastic electrode, and the first circuit board being electrically connected to the second circuit board through the elastic electrode; and / or

[0025] The physiotherapy device also includes a locking member disposed on the fixed base and / or the main unit. The locking member is capable of preventing the winding assembly from rotating relative to the fixed base in the first direction, so as to keep the connecting wire in the pulled-out state.

[0026] In one embodiment, there are multiple massage heads, connecting lines, and winding mechanisms.

[0051] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. 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 physiotherapy device 10 of this application includes a massage head 1, a main unit 2, and a winding mechanism 4. On the one hand, the main unit 2 is connected to the massage head 1 through a connecting cable 3. The connection between the main unit 2 and the massage head 1 is detachable. When in use, the user can hold the massage head 1 and flexibly adjust the direction of force and the contact angle of the massage head 1, thereby improving the flexibility of the physiotherapy operation. In addition, compared to holding the entire physiotherapy device 10, the user only needs to hold the lighter massage head 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 cable 3 into the storage compartment 21 without manual winding, which can save time and simplify the storage operation. In addition, the connecting cable 3 can be stored in the storage compartment 21 inside the main unit 2, which can improve the structural compactness of the physiotherapy device 10, reduce the overall space occupied by the physiotherapy device 10, and facilitate the carrying, storage and transportation of the physiotherapy device 10. Furthermore, the fact that the connecting cable 3 can be stored in the storage compartment 21 inside the main unit 2 can reduce the contamination of the connecting cable 3 by external dust, impurities and other pollutants. At the same time, at least part of the connecting cable 3 is hidden inside the main unit 2, making the overall appearance of the physiotherapy device 10 more concise and beautiful.

[0053] In this embodiment, the massage head 1 is used to contact the skin. The massage head 1 may include one or more combinations of rollers, a hot compress module, a cold compress module, a microcurrent electrode, a phototherapy module, and a vibration module. When using the physiotherapy device 10, the user can use it by holding the massage head 1 to perform physiotherapy on the user's lips, face, nose, or other parts of the skin.

[0054] In this embodiment, the massage head 1 may include a ball bearing. When in use, the ball bearing 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.

[0055] In this embodiment, the massage head 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.

[0056] In this embodiment, the massage head 1 may include a cooling module. When the surface of the cooling module comes into contact with the skin, the epidermal temperature is lowered through direct heat conduction, thereby achieving a physiotherapy effect.

[0057] In this embodiment, the massage head 1 may include a microcurrent electrode, which can emit a microcurrent to stimulate skin cells, thereby achieving a physiotherapy effect.

[0058] In this embodiment, the massage head 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.

[0059] In this embodiment, the massage head 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 a therapeutic effect.

[0060] In this embodiment, the massage head 1 may include a vibration module, which can gently stimulate the skin through vibration while applying skin care products, thereby promoting blood circulation, accelerating the penetration and absorption of skin care products, and enhancing the skin care effect.

[0061] 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 shell 22 of the main unit 2.

[0062] In this embodiment, it should be noted that when using the physiotherapy device 10, the massage head 1 can be separated from the main unit 2 and electrically connected to the main unit 2 through the connecting line 3. The main unit 2 and the massage head 1 can be detachably connected. The winding mechanism 4 can wind up the entire section of the connecting line 3 that is stretched out of the main unit 2 into the receiving chamber 21. The winding mechanism 4 can also wind up a portion of the section of the connecting line 3 that is stretched out of the main unit 2 into the receiving chamber 21. This is not limited here.

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

[0064] In one embodiment, the physiotherapy device further includes a wireless communication module (e.g., Bluetooth or Wi-Fi), through which the main unit can connect to the massage head. 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 massage head 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 main unit 2 can control the operation of the massage head through the wireless communication module.

[0065] In one embodiment, reference Figure 12 and Figure 13The massage head 1 includes a handle 11 and multiple therapy modules. The therapy modules have different functions, and each module is detachably connected to the handle 11. This allows users to easily replace modules with different functions according to their needs. The therapy modules can be easily replaced, and the therapy functions may include, but are not limited to, roller therapy, hot compress therapy, cold compress therapy, microcurrent stimulation therapy, phototherapy, vibration therapy, and iontophoresis therapy. For example, the massage head 1 includes a handle 11, a first therapy module, and a second therapy module. The handle 11 has 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 wire 3 and the conductive terminals 115, respectively. The two conductive terminals 115 are located at one end of the handle 11. The first therapy 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 therapy module is magnetically fixed to the handle 11 by the first magnet 113 and the second magnet 15. When the first therapy module is fixed to the handle 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 therapy 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 therapy module is magnetically fixed to the handle 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 can be detachably connected to the handle 11 by means of snap-fit ​​connection, screw connection, threaded connection, etc., which is not limited here.

[0067] In one embodiment, the physiotherapy 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 massage head 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 massage head 1 with specific physiotherapy functions for physiotherapy based on the detection results. When the physiotherapy device includes multiple massage heads 1, the skin detection sensor can be mounted on one of the massage heads 1, or it can be mounted on each massage head 1; this is not limited here.

[0068] In one embodiment, reference Figure 11When the massage head 1 is placed on the main unit 2, at least part of the massage head 1 is exposed outside the main unit 2. Users can directly grab the exposed part of the massage head 1 to take it out for use, making it more convenient to grab the massage head 1.

[0069] In one embodiment, reference Figure 2 , Figure 4 and Figure 5 The main unit 2 has a housing 22, with a receiving compartment 21 disposed within the housing 22. A receiving groove 23 for accommodating the massage head 1 is formed on the outer wall of the housing 22, and the receiving groove 23 communicates with the receiving compartment 21. One end of a connecting cable 3 is fixedly connected to a winding mechanism 4, and the other end is fixedly connected to the massage head 1. When the winding mechanism 4 automatically winds the connecting cable 3 into the receiving compartment 21, the connecting cable 3 can drive the massage head 1 to move, so that the massage head 1 moves into the receiving groove 23. In this embodiment, when the winding mechanism 4 retracts the connecting cable 3, it directly drives the massage head 1 into the receiving groove 23 of the housing, eliminating the need for the user to manually place the massage head 1, thus achieving automatic retrieval of the massage head 1 and reducing the risk of loss. Furthermore, with at least a portion of the massage head 1 retracted into the receiving groove 23, the overall appearance of the machine is more streamlined, and the risk of damage to the massage head 1 from impacts by external components is also reduced.

[0070] In this embodiment, when using the physiotherapy device 10, the user can hold the outer shell 22 for use. The receiving compartment 21 is set in the outer shell 22. The outer side wall of the outer shell 22 is provided with a receiving groove 23 for receiving the massage head 1. The massage head 1 is detachably connected to the receiving groove 23. When the massage head 1 is placed in the receiving groove 23, at least part of the massage head 1 is exposed outside the receiving groove 23. The user can directly grab the massage head 1 and pull it out for use. There is no need to set up a separate storage box to place the massage head 1, and the step of manually opening the storage box is also eliminated. The operation of taking out the massage head 1 is more convenient.

[0071] In one embodiment, reference Figure 2 and Figure 4 The winding mechanism 4 is located in the receiving chamber 21. The groove wall of the receiving slot 23 has a wire hole 231 communicating with the receiving chamber 21. One end of the connecting wire 3 is fixedly connected to the winding mechanism 4, and the other end passes through the wire hole 231 and is fixedly connected to the massage head 1. In this embodiment, the connecting wire 3 can pass through the wire hole 231, but the massage head 1 cannot pass through the wire hole 231. When the winding mechanism 4 retracts the connecting wire 3, it can drive the massage head 1 into the receiving slot 23 of the outer shell. The groove wall of the receiving slot 23 can block the receiving slot 23 and the receiving chamber 21, so that the massage head 1 will not be pulled into the receiving chamber 21. The massage head 1 can be received in the receiving slot 23 on the outer side wall of the outer shell 22, which makes it convenient for the user to directly take the massage head 1 from the outer side wall of the outer shell 22 for use.

[0072] 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.

[0073] In one embodiment, the physiotherapy device 10 also includes fasteners (not shown in the figure). The massage head 1 is detachably fixed in the receiving groove 23 by the fasteners, which can ensure that the massage head 1 is firmly fixed in the storage state and prevent the massage head 1 from falling out of the receiving groove 23 due to accidental touch or vibration.

[0074] In this embodiment, the type of fastener is not limited. For example, the fastener may include a first magnetic element and a second magnetic element that attract each other. The first magnetic element is fixed to the wall of the receiving groove 23, and the second magnetic element is fixed to the massage head 1. When the massage head 1 is placed in the receiving groove 23, the first magnetic element and the second magnetic element attract each other to fix the massage head 1 in the receiving groove 23. As another example, the fastener may include a snap-fit ​​assembly, which includes a snap-fit ​​provided on the wall of the receiving groove 23 and a slot provided on the massage head 1. When the massage head 1 is placed in the receiving groove 23, the snap-fit ​​and the slot engage with each other to fix the massage head 1 in the receiving groove 23.

[0075] In one embodiment, reference Figure 3 The massage head 1 includes a handle 11 and a conductive electrode 12 fixedly connected to it. At least a portion of the conductive electrode 12 protrudes from the handle 11 to contact the skin. A connecting wire 3 is electrically connected to the conductive electrode 12. Current is applied to the skin surface through the conductive electrode 12. 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.

[0076] In this embodiment, the handle 11 has a mounting chamber 111, and one end of the handle 11 has a wire insertion hole 112 communicating with the mounting chamber 111. A conductive electrode 12 is fixed to the end of the handle 11 away from the wire insertion hole 112, and the conductive electrode 12 is in communication with the mounting chamber 111. The connecting wire 3 can pass through the wire insertion hole 112 and enter the mounting chamber 111 to directly contact the conductive electrode 12. In this embodiment, the conductive electrode 12 can be entirely protruding from the handle 11, or a portion of the conductive electrode 12 can be located in the mounting chamber 111, while another portion protrudes from the handle 11; this is not limited. In this embodiment, the connecting wire 3 can be fixedly connected to the conductive electrode 12 by welding, screw connection, or other methods.

[0077] In one embodiment, reference Figure 2The receiving groove 23 includes a bottom wall 232 and a side wall 233 connected to each other. The side wall 233 surrounds the outer periphery of the bottom wall 232. The bottom wall 232 includes a first bottom wall 2321 and a second bottom wall 2322 connected in sequence. The second bottom wall 2322 is recessed inward relative to the first bottom wall 2321. When the massage head 1 is fixed in the receiving groove 23, the conductive electrode 12 is spaced apart from the second bottom wall 2322. In this embodiment, when the winding mechanism 4 automatically retracts the massage head 1 into the receiving groove 23, the first bottom wall 2321 is correspondingly arranged with the handle 11, and the second bottom wall 2322 is face-to-face with the conductive electrode 12. The second bottom wall 2322 is recessed inward relative to the first bottom wall 2321. Because the connecting line 3 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 massage head 1 swings with the movement of the connecting line 3; the conductive electrode 12 is spaced apart from the second bottom wall 2322, and the side wall 233 is spaced apart from the massage head 1. The receiving groove 23 has a swing margin for the massage head 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 bottom wall 232 and the side wall 233, which can reduce the risk of damage to the conductive electrode 12 or poor electrical contact caused by collision.

[0078] In one embodiment, the side wall 233 has an opening at the end away from the bottom wall 232, through which the massage head 1 can enter or leave the receiving groove 23. The massage head 1 can be received in the receiving groove 23 on the outer side wall of the outer shell 22, so that the user can directly take the massage head 1 from the outer side wall of the outer shell 22 for use.

[0079] In one embodiment, reference Figure 11 When the massage head 1 is placed in the receiving groove 23, at least part of the conductive electrode 12 is exposed outside the main unit 2 through the opening. When the user grasps the outer shell 22, without removing the massage head 1 from the receiving groove 23, the hand can directly contact the exposed conductive electrode 12, which facilitates the formation of a current circuit between the skin and the conductive electrode 12.

[0080] In one embodiment, reference Figure 2 The sidewall 233 includes a first sidewall 2331 and a second sidewall 2332 connected to each other. The first sidewall 2331 is disposed at the edge of the first bottom wall 2321, and the second sidewall 2332 is disposed at the edge of the second bottom wall 2322. The second sidewall 2332 is an arc-shaped sidewall, and the height of the second sidewall 2332 gradually decreases in the direction away from the first bottom wall 2321, which can reduce the risk of the second sidewall 2332 colliding with the conductive electrode 12 and causing damage to the conductive electrode 12. In this embodiment, the height of the second sidewall 2332 refers to the distance between the end of the second sidewall 2332 and the reference plane in the radial direction of the host, with the plane where the second bottom wall is located as the reference plane.

[0081] The gradually decreasing height of the second sidewall 2332 forms a "guide ramp," allowing the massage head 1 to slide smoothly into the receiving groove 23, making it easier for the massage head 1 to enter the receiving groove 23. Furthermore, the height of the second sidewall 2332 gradually decreases in the direction away from the first bottom wall 2321, reducing the obstruction of the massage head 1 by the second sidewall 2332. Even if the massage head 1 slightly collides with the second sidewall 2332, the small contact area reduces the risk of damage to the massage head 1. Simultaneously, when the massage head 1 is installed in the receiving groove 23, the second sidewall 2332 obstructs the conductive electrode 12 less, resulting in a larger exposed area for the conductive electrode 12. This makes it easier for the user's hand to contact the conductive electrode 12 when holding the outer casing 22 with one hand.

[0082] In one embodiment, reference Figure 4 and Figure 6 The winding mechanism 4 includes a fixed base 41 and a winding assembly 42. 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.

[0083] 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 massage head 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.

[0084] 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 winding 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 winding 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 cable outlet 413 communicating with the cable receiving cavity. The cavity wall of the receiving chamber 21 is provided with a second cable outlet 211 communicating with the first cable outlet 413 and the cable passage hole 231. One end of the connecting cable 3 is fixed to the cylinder 4211, and the other end passes through the first cable outlet 413, the second cable outlet 211 and the cable passage hole 231 in sequence and is fixedly connected to the massage head 1. When the massage head 1 or the connecting cable 3 is pulled outward, the connecting cable 3 can drive the cylinder 4211 to rotate relative to the insertion post 412 in the second direction to release the connecting cable 3 on the cylinder 4211. When the cylinder 4211 rotates relative to the insertion post 412 in the second direction, the elastic element 44 can undergo elastic deformation. When the external force on the massage head 1 and / or the connecting cable 3 is removed, the cylinder 4211 can rotate relative to the insertion post 412 in the first direction under the reset force of the elastic element 44, so that the connecting cable 3 automatically winds around the cylinder 4211.

[0085] 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 wire passage 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 wire passage hole 231 in sequence and is fixedly connected to the massage head 1. The winding 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 insertion post 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 insertion post 412 so that the connecting wire 3 is automatically wound around the cylinder 4211.

[0086] In one embodiment, reference Figure 6 The winding 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 winding assembly 42. When the massage head 1 and / or the connecting line 3 are subjected to tension, the connecting line 3 can drive the winding assembly 42 to rotate relative to the fixed base 41 in a second direction to release the connecting line 3 on the winding assembly 42. When the winding assembly 42 rotates in the second direction, the elastic element 44 can undergo elastic deformation. When the external force on the massage head 1 and / or the connecting line 3 is removed, the winding 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 line 3 automatically winds around the winding assembly 42. In this embodiment, the reset force of the elastic element 44 is used to drive the winding 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.

[0087] 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.

[0088] 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 fixed base 41. One end of the connecting wire 3 is fixed to the drum 421 and 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 fixed 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.

[0089] 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 handle 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 handle 11 can be made of conductive metal materials such as stainless steel or silver. During operation, the handle 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 holds the handle 11 and the conductive electrode 12 comes into contact with the skin.

[0090] In one embodiment, reference Figure 2The system comprises multiple massage heads 1, connecting cables 3, and winding mechanisms 4. Each massage head 1 is electrically connected to the main unit 2 via a corresponding connecting cable 3. Each winding mechanism 4 automatically winds up its corresponding connecting cable 3 into the receiving compartment 21. In this embodiment, multiple massage heads 1 can simultaneously act on different parts of the body (such as the shoulders and neck, waist, legs, etc.), reducing the inconvenience of repeatedly moving a single massage head 1. For example, the system may also have two massage heads 1, connecting cables 3, and winding mechanisms 4. Each massage head 1 is electrically connected to the main unit 2 via a corresponding connecting cable 3, and each winding mechanism 4 automatically winds up its corresponding connecting cable 3 into the receiving compartment 21.

[0091] In one specific embodiment, reference is made to Figure 2 The massage head 1, connecting wire 3, and winding mechanism 4 are all in pairs. 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.

[0092] In one embodiment, reference Figure 7 The physiotherapy 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.

[0093] In one embodiment, reference Figure 7 The physiotherapy 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.

[0094] In one embodiment, reference Figure 8 The physiotherapy 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 the connecting wire 3 to the required length according to the physiotherapy 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 physiotherapy operation.

[0095] 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 winding 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 cable outlet 413 communicating with the cable receiving cavity. The cavity wall of the receiving chamber 21 is provided with a second cable outlet 211 communicating with the first cable outlet 413 and the cable passage hole 231. One end of the connecting cable 3 is fixed to the cylinder 4211, and the other end passes through the first cable outlet 413, the second cable outlet 211 and the cable passage hole 231 in sequence and is fixedly connected to the massage head 1. When the massage head 1 or the connecting cable 3 is pulled outward, the connecting cable 3 can drive the cylinder 4211 to rotate relative to the insertion post 412 in the second direction to release the connecting cable 3 on the cylinder 4211. When the cylinder 4211 rotates relative to the insertion post 412 in the second direction, the elastic element 44 can undergo elastic deformation. When the external force on the massage head 1 and / or the connecting cable 3 is removed, the cylinder 4211 can rotate relative to the insertion post 412 in the first direction under the reset force of the elastic element 44, so that the connecting cable 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 outer casing 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.

[0096] 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 winding mechanism 4 also includes a cover 43, which is fixedly connected to the fixed seat 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 unwinding normally; the reset section is the movement trajectory of the ball when the connecting line 3 resumes automatic winding. 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.

[0097] 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.

[0098] 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.

[0099] In this embodiment, the length of the connecting line 3 is 0.4 meters to 1 meter. If the length of 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 physiotherapy device 10. If the length of the connecting line 3 is too short, it will easily reduce the radius of motion of the massage head 1 and reduce the operational flexibility of the massage head 1.

[0100] 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 winding mechanisms 4 are located. The multiple winding mechanisms 4 are stacked along the axial direction of the receiving chamber 21, and the multiple winding 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 winding mechanism 4 along the axial direction. There is no need to set a partition between the multiple winding mechanisms 4, which can further reduce the volume of the receiving chamber 21 and reduce the axial shaking of the winding mechanism 4 when the physiotherapy device 10 moves. Furthermore, the cross-sectional shape of the winding 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 axial direction 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 winding mechanism 4 through physical blocking of the corners. Moreover, the polygonal adaptation structure locks the winding 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 physiotherapy device 10.

[0101] In this embodiment, the cross-sectional shape of the limiting wall 214 can be triangular, quadrilateral, pentagonal, hexagonal, etc., and is not limited here.

[0102] This application also provides a physiotherapy device 100, which includes a container 20 and a physiotherapy instrument 10 as described above. The container 20 is fixedly connected to the physiotherapy instrument 10 and is used to store skincare products. The physiotherapy instrument 10 and the container 20 are assembled together, which makes it convenient for users to directly take out the massage head 1 to treat their skin after using skincare products, so as to promote the absorption of skincare products and avoid the need for users to search for the physiotherapy instrument 10 separately. It also allows the physiotherapy instrument 10 to be carried along with skincare products, improving the convenience of use.

[0103] In this embodiment, the method of fixing the container 20 to the physiotherapy device 10 is not limited. For example, the inner wall surface of one end of the outer shell 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 outer shell 22. As another example, the inner wall surface of one end of the outer shell 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 snap-fit ​​connected to one end of the outer shell 22.

[0104] 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.
