[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present utility model and are not intended to limit the present utility model. In the present utility model, 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.
[0019] Please refer to Figure 1 and Figure 2 The physiotherapy device 100 of this application includes a main unit 1 and a physiotherapy head 2, which is used to stimulate the skin to perform physiotherapy. The main unit 1 includes a handle 11 and a mounting arm 12 connected at an angle. Compared to a handle 11 and mounting arm 12 connected in a straight line, the angled connection between the handle 11 and mounting arm 12 can reduce the overall height of the main unit 1. In addition, the treatment head 2 for skin physiotherapy is rotatably connected to the mounting arm 12 so that the treatment head 2 can switch between an unfolded state and a folded state. When in use, the treatment head 2 can be in the unfolded state. After use, the treatment head 2 can be rotated so that the treatment head 2 is stored in the storage space 13 formed by the mounting arm 12 and the handle 11. The space of the main unit 1 itself can be fully utilized to store the treatment head 2, making the structure of the physiotherapy device 100 more compact. When in the folded state, the projection of the treatment head 2 in the first direction completely overlaps with the projection of the main unit 1 in the first direction. The first direction is perpendicular to the axis of the handle 11. That is, in the first direction, the treatment head 2 will not protrude from the outer contour of the main unit 1, which can reduce the storage area of the physiotherapy device 100. The space occupied by the physiotherapy device is small, which is conducive to the storage and carrying of the physiotherapy device.
[0020] In this embodiment, the handle 11 and the mounting arm 12 can be integrally formed and connected. Alternatively, the handle 11 and the mounting arm 12 can be fixedly connected by means of screws, snap-fit connections, welding, or bonding. When the therapy head 2 is in the folded state, it can be partially or completely stored in the storage space 13, which is not limited here.
[0021] In one specific embodiment, reference is made to Figure 1 and Figure 8The axis of the handle 11 can be vertical, and the first direction is either front-back or left-right. The mounting arm 12 is fixed above the handle 11. One side wall of the mounting arm 12 and the top arm of the handle 11 form a storage space 13. When the physiotherapy head 2 is in the folded state, part of the physiotherapy head 2 is housed in the storage space 13.
[0022] In one embodiment, reference Figure 1 , Figure 1 This is the front view of the physiotherapy device. Figure 1 In the diagram, W1 represents the axial direction of handle 11, and the axial direction of handle 11 is the up-down direction. Figure 1 In the diagram, the W2 direction is the left-right direction, and the first direction is the front-back direction. The first direction is perpendicular to both the W1 and W2 directions. When the therapy head 2 is in a folded state, the projection of the therapy head 2 in the front-back direction completely overlaps with the projection of the host 1 in the front-back direction.
[0023] In another embodiment, reference Figure 10 and Figure 11 The main unit 1 also includes a baffle 19, which is located at the edge of one side wall of the mounting arm 12. The baffle 19 provides protection for the therapy head. The mounting arm 12, the baffle 19, and the handle 11 together form a receiving space. Figure 10 In the diagram, W1 represents the axial direction of handle 11, and the axial direction of handle 11 is the up-down direction. Figure 10 In the diagram, the W3 direction is the front-to-back direction, and the first direction is the left-to-right direction. The first direction is perpendicular to both the W1 and W3 directions. When the therapy head 2 is in the folded state, the therapy head 2 is located in the storage space, and the projection of the therapy head 2 in the left-to-right direction completely overlaps with the projection of the host 1 in the left-to-right direction.
[0024] Optionally, the therapy head 2 may be provided with a stimulation element for stimulating the skin to provide physiotherapy. The stimulation element may include one or more combinations of rollers, heating elements, cooling elements, microcurrent electrodes, phototherapy components, and vibration components.
[0025] For example, the treatment head 2 may include a roller ball, which, when in use, applies pressure to the skin through physical rolling, widening the gaps between the stratum corneum and promoting the transdermal absorption of active ingredients.
[0026] For example, the therapy head 2 may include a heating element, which, when in use, can transfer heat to the skin to achieve physiological effects such as vasodilation and promote the absorption of active ingredients through the skin.
[0027] For example, the physiotherapy head 2 may include a cooling compress. When the surface of the cooling compress comes into contact with the skin, the epidermal temperature drops rapidly through direct heat conduction, thereby achieving a physiotherapy effect.
[0028] For example, the therapy head 2 may include a microcurrent electrode that can emit a microcurrent to stimulate the skin, thereby improving the skin care therapy effect.
[0029] For example, the therapy head 2 may include a phototherapy component, which, when in use, can irradiate the skin with light emitted by the phototherapy component to achieve a phototherapy effect.
[0030] For example, the therapy head 2 may include a vibration component that gently stimulates the skin with vibration while applying skincare products, which helps promote blood circulation, accelerates the penetration and absorption of skincare products, and enhances the skincare effect.
[0031] In one embodiment, when the therapy head 2 is in the unfolded state, the free end 21 of the therapy head 2 is away from the storage space 13, and the vertical distance between the center of mass of the therapy head 2 and the central axis of the handle 11 is D, where D≤3mm. When using the therapy device 100, the user generally holds the handle 11, and with D≤3mm, the center of mass of the therapy head 2 is close to the axis of the handle 11. This reduces the need for the hand to exert extra force to resist the tipping tendency caused by the weight of the therapy head 2 itself, making operation easier and reducing wrist and arm fatigue. Optionally, the vertical distance D between the center of mass of the therapy head 2 and the central axis of the handle 11 can be any one or any two of 0mm, 0.5mm, 1mm, 2mm, 2.5mm, 3mm, etc., and is not limited here.
[0032] In one embodiment, reference Figure 2 The treatment head 2 is rotatably connected to the side of the mounting arm 12 away from the handle 11. This increases the distance between the treatment head 2 and the handle 11, making it less likely for the target skin to come into contact with the handle 11 or the human hand when the treatment head 2 is in contact with or close to the target skin.
[0033] In one embodiment, reference Figures 2 to 7The physiotherapy head 2 includes a housing 22, a post 23, and a first guide portion 24. The post 23 protrudes from the outer wall of the housing 22 and has a shaft hole 231. The first guide portion 24 is disposed on the post 23 and located on the outer periphery of the shaft hole 231. The mounting arm 12 has a rotating shaft 121 and a second guide portion 122 on the side facing the housing 22. The second guide portion 122 is located on the outer periphery of the rotating shaft 121. The rotating shaft 121 is inserted into the shaft hole 231 to connect with the rotating shaft 121 of the post 23. One of the second guide portion 122 and the first guide portion 24 is a guide groove, and the other is an insert block. The rotating shaft 121 is coaxially arranged with the guide groove, and the insert block is inserted into the guide groove to limit the rotational stroke of the physiotherapy head 2 relative to the mounting arm 12. On the one hand, the second guide part 122 and the first guide part 24 can play a guiding role, making the rotation of the physiotherapy head 2 more stable; on the other hand, the second guide part 122 and the first guide part 24 can limit the rotation stroke of the physiotherapy head 2 relative to the mounting arm 12, prevent the physiotherapy head 2 from rotating excessively relative to the mounting arm 12, and reduce the problem of the connecting wire between the physiotherapy head 2 and the main unit 1 getting tangled.
[0034] In this embodiment, the second guide portion 122 can be an insert block, and the first guide portion 24 can be a guide groove; or, the second guide portion 122 can be a guide groove, and the first guide portion 24 can be an insert block.
[0035] In one embodiment, reference Figure 4 The physiotherapy head 2 also includes a bearing 16, which is sleeved on the end of the rotating shaft 121 away from the housing 22. The bearing 16 is used to prevent the insertion post 23 from disengaging from the rotating shaft 121.
[0036] In one embodiment, reference Figures 5 to 7The mounting arm 12 also includes a limiting member 123, which is located on the outside of the rotating shaft 121. The limiting member 123 includes an elastic arm 1231 and a protrusion 1232 on the elastic arm 1231. The side of the insert post 23 facing the limiting member 123 is provided with a plurality of positioning grooves 25. The plurality of positioning grooves 25 are distributed circumferentially along the shaft hole 231. When the housing 22 rotates, it can drive the protrusion 1232 to rotate relative to the positioning groove 25, so that the protrusion 1232 can be engaged or disengaged from the positioning groove 25. Specifically, when the housing 22 of the physiotherapy head 2 rotates relative to the rotating shaft 121, the positioning groove 25 rotates synchronously with the housing 22. When the positioning groove 25 rotates to the limiting member 123, the protrusion 1232 of the limiting member 123 can be inserted into the corresponding positioning groove 25. At this time, after the external force applied to the physiotherapy head 2 is removed, the concave-convex fit between the limiting member 123 and the positioning groove 25 can prevent the physiotherapy head 2 from rotating further, so that the physiotherapy head 2 can rotate to a specific position. When the physiotherapy head 2 continues to rotate, the groove wall of the positioning groove 25 squeezes the protrusion 1232 of the limiting member 123, causing the elastic arm 1231 to undergo elastic deformation. The elastic arm 1231 drives the protrusion 1232 to move away from the positioning groove 25, and the physiotherapy head 2 can continue to rotate.
[0037] In this embodiment, on the one hand, the number of positioning grooves 25 is two, three, or more, allowing the user to insert the limiting member 123 into different positions of the positioning grooves 25 to flexibly adjust the angle between the therapy head 2 and the mounting arm 12, thereby meeting different user needs. On the other hand, the limiting member 123 can produce a locking sensation when it is inserted into or removed from the positioning groove 25, which can improve the user's feel when rotating the therapy head 2 and also indicate to the user whether it has been rotated to the correct position.
[0038] In this embodiment, in order to reduce the friction between the positioning groove 25 and the limiting member 123, and to facilitate the sliding of the protrusion 1232 of the limiting member 123 into and out of the positioning groove 25, the protrusion 1232 on the elastic arm 1231 is an arc-shaped protrusion 1232, and the groove wall of the positioning groove 25 is an arc-shaped groove wall.
[0039] In this embodiment, the limiting member 123 can be fixed to the mounting arm 12 by means of bonding, screw connection, integral molding, etc., and is not limited here. The connection method between the elastic arm 1231 and the protrusion 1232 is also not limited, and the elastic arm 1231 and the protrusion 1232 can be fixed together by means of bonding, screw connection, integral molding, etc.
[0040] In one specific embodiment, reference is made to Figure 6The positioning groove 25 includes a first positioning groove 251 and a second positioning groove 252. When the protrusion 1232 moves into the first positioning groove 251, the physiotherapy head 2 can remain in a folded state. When the protrusion 1232 moves into the second positioning groove 252, the physiotherapy head 2 can remain in an unfolded state.
[0041] In one embodiment, reference Figure 5 The guide groove is an arc-shaped groove with a central angle of 50°-80°. The central angle of the guide groove refers to the central angle corresponding to the center arc of the guide groove. Optionally, the central angle of the guide groove can be any one or any two of 50°, 60°, 70°, and 80°, and is not limited here. In this embodiment, the size of the central angle of the guide groove limits the rotation angle of the therapy head 2. Setting the central angle of the guide groove to 50°-80° prevents the rotation angle of the therapy head 2 from being too large, reducing the problem of the connecting wires getting tangled due to excessive rotation angle.
[0042] In one embodiment, reference Figure 5 The mounting arm 12 has a recessed groove 17 on the side facing the housing 22. The rotating shaft 121 is disposed in the recessed groove 17, and the second guide part 122 is disposed on the groove wall of the recessed groove 17. An installation gap is formed between the groove wall of the recessed groove 17 and the rotating shaft 121, and the insertion post 23 is located in the installation gap. On the one hand, the installation gap can provide initial positioning for the insertion post 23, making it easy for the insertion post 23 to be quickly inserted into the preset position; on the other hand, when the insertion post 23 is inserted into the recessed groove 17 and the rotating shaft 121 is inserted into the shaft hole 231 of the insertion post 23, the groove wall of the recessed groove 17 can cover at least part of the insertion post 23, reducing the exposure of the insertion post 23 and improving the aesthetics of the physiotherapy device 100.
[0043] In one embodiment, the angle between the central axis of the handle 11 and the central axis of the mounting arm 12 is 120°-160°. Optionally, the angle between the central axis of the handle 11 and the central axis of the mounting arm 12 can be any one or any two of 120°, 130°, 140°, 150°, 160°, etc., and is not limited herein. With an angle of 120°-160° between the central axis of the handle 11 and the central axis of the mounting arm 12, the user can reduce excessive bending or straightening of the wrist when using the physiotherapy device, thereby reducing the risk of wrist fatigue.
[0044] In one embodiment, reference Figure 7The therapy head 2 includes a housing 22, a first circuit board 26, and multiple light sources 28. The first circuit board 26 and the multiple light sources 28 are electrically connected, and each light source 28 can emit at least two different colors of light. The housing 22 has a light-transmitting area, and the first circuit board 26 and the light sources 28 are both located within the housing 22, with the light sources 28 facing the light-transmitting area. In this embodiment, the light emitted by the light sources 28 can pass through the light-transmitting area of the housing 22 and reach the skin for phototherapy. Furthermore, each light source 28 can emit at least two different colors of light, and multiple light sources 28 can be combined to form various patterns, increasing the interest of the therapy device 100.
[0045] In one embodiment, reference Figure 7 The therapy head 2 also includes conductive electrodes 27 electrically connected to the first circuit board 26, with at least a portion of the conductive electrodes 27 protruding from the housing 22 to contact the skin. The number of conductive electrodes 27 can be two or more. After multiple conductive electrodes 27 come into contact with the skin, a current loop can be formed between the first circuit board 26, the conductive electrodes 27, and the skin to provide therapy to the skin.
[0046] In one embodiment, reference Figure 7The therapy head 2 includes a housing 22, a stimulation element, a first circuit board 26, and a button 29. The first circuit board 26 is electrically connected to the stimulation element and is located in the housing 22. The outer peripheral wall of the housing 22 is provided with a mounting groove 221. The groove wall of the mounting groove 221 is provided with a through hole 222 communicating with the first circuit board 26. The outer periphery of the through hole 222 is provided with an elastic part 223, which forms part of the groove wall. The outer periphery of the elastic part 223 is provided with a notch 224. The button 29 is movably disposed in the mounting groove 221. The button 29 includes a pressing part 291 and a plugging part 292. The plugging part 292 is fixed to the side of the pressing part 291 facing the through hole 222. The plugging part 292 is provided with a buckle 293. After the plugging part 292 passes through the through hole 222, the groove wall is sandwiched between the pressing part 291 and the buckle 293. The pressing part 291 and the elastic part 223 are disposed opposite to each other. In this embodiment, after pressing the pressing part 291 of the button 29, the pressing part 291 compresses the elastic part 223, causing the elastic part 223 to undergo elastic deformation. The insertion part 292 can move along the through hole 222 to contact the first circuit board 26. After the first circuit board 26 detects the pressing signal, it can control the stimulation element to work. After releasing the button 29, the pressing part 291 is driven to move away from the first circuit board 26 under the action of the elastic restoring force of the elastic part 223. The buckle 293 on the insertion part 292 can prevent the insertion part 292 from disengaging from the groove wall of the mounting groove 221. In addition, the elastic part 223 forms part of the groove wall. The outer periphery of the elastic part 223 has a notch 224. The notch 224 makes it easier for the elastic part 223 to undergo elastic deformation. A part of the groove wall is directly used as the elastic part 223, eliminating the need for additional elastic components and saving parts.
[0047] In one embodiment, reference Figure 7 The button 29 also includes guide posts 294, which are distributed around the outer periphery of the insertion portion 292. A guide hole 295, adapted to the guide post 294, is also provided on the groove wall, and the guide post 294 is inserted into the guide hole 295. The guide post 294 and the guide hole 295 provide guidance for the movement of the button 29, making the movement of the button 29 more stable.
[0048] In one embodiment not shown, the pressing part 291 has an insertion hole, and the groove wall is also provided with a guide block adapted to the insertion hole, which is inserted into the insertion hole. The guide block and the insertion hole can provide guidance for the movement of the button 29, making the movement of the button 29 more stable.
[0049] In one embodiment, reference Figure 9 The host 1 also includes a main circuit board 14, a battery 15 and a charging interface 18. The first circuit board 26 and the battery 15 are both electrically connected to the main circuit board 14, and the battery 15 is used to supply power to the main circuit board 14.
