Description

Technical Field

[0001] This application belongs to the field of skin care technology, and more specifically, relates to an unfoldable therapeutic cover. Background Technology

[0002] With the popularization of phototherapy technology, home phototherapy devices are becoming increasingly popular, especially portable products for facial or localized body care. These products are generally designed as handheld devices or with caps that come with specific containers (such as skincare bottles) to meet users' needs for convenient daily home care.

[0003] However, to ensure the portability and compactness of existing cap-style phototherapy devices, the overall size of the device remains small. This results in a small coverage area per irradiation. When users need to treat larger areas such as the forehead or cheeks, they must repeatedly move the device to ensure that the irradiated spot covers the entire target area. This process is cumbersome and time-consuming, and manual movement makes it difficult to ensure uniform irradiation distance and angle, thus affecting the effectiveness of phototherapy and the user experience.

[0004] Therefore, there is an urgent need for a new technology that can solve the problem of frequent relocation of phototherapy instruments during the nursing process in existing technologies, while maintaining the portability and easy storage characteristics of the equipment. Utility Model Content

[0005] This application provides an unfoldable physiotherapy cover that is small in size, easy to store, and does not require frequent repositioning during use.

[0006] The technical solution adopted in this application embodiment is: providing an unfoldable physiotherapy cover, including: A lid for detachable connection to the container; and A phototherapy assembly includes a first phototherapy plate and a second phototherapy plate. The first phototherapy plate has a first light-emitting surface, and the second phototherapy plate has a second light-emitting surface that is in the same direction as the first light-emitting surface. Wherein, one end of the first phototherapy plate is rotatably connected to the cover, so that the first phototherapy plate can rotate between a folded position that fits the cover and an unfolded position that forms an angle with the cover; The second light therapy plate is slidably connected to the first light therapy plate so that the second light therapy plate can slide between a retracted position stacked on the first light therapy plate and an extended position where the second light-emitting surface extends out of the first light therapy plate; The phototherapy component has a storage state and a working state; In the stored state, the first light therapy plate is in the folded position and the second light therapy plate is in the retracted position; in the working state, the first light therapy plate is in the unfolded position and the second light therapy plate is in the extended position, with the first light-emitting surface and the second light-emitting surface together forming an extended irradiation surface.

[0007] Furthermore, the cover has a receiving groove on the side opposite to the container, and one end of the first phototherapy plate is pivotally connected to the receiving groove via a horizontal shaft so that it sinks into the receiving groove when in the folded position.

[0008] Furthermore, the depth of the receiving groove is adapted to the thickness of the phototherapy component in its stored state, so that when the phototherapy component is in its stored state, both the first phototherapy plate and the second phototherapy plate are embedded in the receiving groove.

[0009] Furthermore, it also includes a magnetic attraction component, the magnetic attraction component comprising: The first magnetic suction element is disposed on the side of the first phototherapy plate opposite to the first light-emitting surface; The second magnetic suction element is disposed on the first groove wall of the receiving groove; When the first light therapy plate is rotated to the unfolded position, the side of the first light therapy plate away from the first light-emitting surface is in contact with the first groove wall, and the second magnetic suction member is attracted and fixed to the first magnetic suction member to keep the first light therapy plate in the unfolded position.

[0010] Furthermore, the unfoldable therapy cover also includes: A detection element is disposed on the first phototherapy plate and is used to generate a trigger signal when the first magnetic suction component and the second magnetic suction component are attracted together. The control circuit board is electrically connected to the detection element and the phototherapy assembly, and upon receiving the trigger signal, drives the first light-emitting surface and the second light-emitting surface to emit therapeutic light.

[0011] Furthermore, the detection element is a Hall sensor, which is disposed adjacent to the first magnetic attractor and uses the magnetic field of the first magnetic attractor as the detection object; When the first magnetic attractor and the second magnetic attractor are attracted to each other, the Hall sensor emits the trigger signal due to the change in magnetic field strength.

[0012] Furthermore, the first phototherapy plate has grooves on both sides, and the second phototherapy plate has sliders on both sides that are adapted to the shape of the grooves.

[0013] Furthermore, it also includes a positioning structure, the positioning structure comprising: A rolling element, wherein the slider is provided with an insert hole, the rolling element is located in the insert hole and can move along the axis of the insert hole; An elastic element is disposed within the mounting hole and pushes the rolling element outward from the mounting hole; The first positioning groove is provided on the groove wall of the slide. When the second phototherapy plate slides to the retracted position, the rolling part protrudes from the mounting hole and is embedded in the first positioning groove. The second positioning groove is provided on the groove wall of the slide. When the second phototherapy plate slides to the extended position, the rolling part protrudes from the mounting hole and is embedded in the second positioning groove.

[0014] Furthermore, the rolling element is a ball, and the outer end of the mounting hole is provided with a constriction, the inner diameter of which is smaller than the diameter of the ball.

[0015] Furthermore, a battery is installed inside the first phototherapy plate; The first phototherapy plate has a strip-shaped clearance groove and a conductive sheet on the side facing the second phototherapy plate. The strip-shaped clearance groove is parallel to the sliding direction of the second phototherapy plate, and the conductive sheet protrudes from one end of the bottom wall of the clearance groove and is electrically connected to the battery. The second phototherapy plate is provided with an elastic conductive head, the elastic conductive head protruding and extending into the clearance groove; When the second phototherapy plate slides from the retracted position to the extended position, the elastic conductive head moves within the clearance groove and contacts the conductive sheet when it reaches the extended position, thereby supplying power to the second phototherapy plate.

[0016] The beneficial effects of the unfoldable therapy cover provided in this application embodiment are as follows: In the unfoldable therapy cover of this application embodiment, the first phototherapy plate of the phototherapy component is rotatably connected to the cover body, and the second phototherapy plate is slidably connected to the first phototherapy plate. This dual movable structure design allows the device to be stored by folding the first phototherapy plate close to the cover body and stacking the second phototherapy plate on top of the first phototherapy plate to retract, switching to the stored state. The overall size remains similar to that of a traditional cover, ensuring that its portability and easy storage characteristics are not affected. In use, the first phototherapy plate can be rotated to the unfolded position at an angle to the cover body, and the second phototherapy plate slides out to the extended position, switching to the working state. This allows the first light-emitting surface of the first phototherapy plate and the second light-emitting surface of the second phototherapy plate to be spliced ​​in the same direction, forming a larger extended irradiation surface. This allows the user to cover a large area such as the forehead and cheeks without frequently moving the instrument, ensuring the uniformity of the irradiation distance and angle in each area, thereby improving the phototherapy effect and user experience.

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0024] Please see Figure 1 and Figure 2 The unfoldable physiotherapy cover provided in the embodiments of this application will now be described. The unfoldable physiotherapy cover provided in the embodiments of this application includes a cover body 1 and a phototherapy component 2.

[0025] Reference Figure 1 and Figure 3 The cap 1 is used for detachable connection with the container 8. The cap 1 is adapted to the bottle mouth of the matching container 8 and can adopt a detachable structure such as threaded engagement or snap-fit. The container 8 can be a skin care product container 8, such as a face cream jar or moisturizing cream jar or other beauty product container 8, etc., and the cap 1 can replace the cap of these containers 8 themselves.

[0026] Reference Figure 1 and Figure 2The phototherapy component 2 includes a first phototherapy plate 21 and a second phototherapy plate 22. The first phototherapy plate 21 has a first light-emitting surface 211, and the second phototherapy plate 22 has a second light-emitting surface 221 that faces the same direction as the first light-emitting surface 211. The phototherapy component 2 is a part for performing physiotherapy. Both the first phototherapy plate 21 and the second phototherapy plate 22 are equipped with phototherapy components. For example, both the first phototherapy plate 21 and the second phototherapy plate 22 have a lamp board inside. The lamp board has LED beads and other light-emitting devices arranged on it and is encapsulated by a transparent material (such as glass, transparent plastic, or acrylic sheet) to form the first light-emitting surface 211 and the second light-emitting surface 221, respectively. The therapeutic light emitted by the light-emitting devices is emitted through this surface to act on the treatment area. In addition, the second phototherapy plate 22 is also used to cooperate with the first phototherapy plate 21 to set the second light-emitting surface 221 to face the same direction as the first light-emitting surface 211, thereby increasing the light-emitting area. The therapeutic light is emitted by the first light-emitting surface 211 and the second light-emitting surface 221. Its wavelength, intensity and other parameters are set according to the physiotherapy needs, such as red light and blue light for skin care.

[0027] Among them, reference Figure 2 and Figure 4 One end of the first light therapy plate 21 is rotatably connected to the cover 1, allowing the first light therapy plate 21 to rotate between a folded position that fits against the cover 1 and an unfolded position that forms an angle with the cover 1. The first light therapy plate 21 can be rotated to fit against the cover 1 or flipped up to form an angle with the cover 1. For example, the bottom surface of the cover 1 is threaded to connect with the container 8, while its upper surface is generally set as a plane. When the first light therapy plate 21 is rotated to fit against this upper surface, the first light therapy plate 21 is placed horizontally to reduce the longitudinal dimension of the entire physiotherapy cover and facilitate storage. When the first light therapy plate 21 is rotated to form an angle with the cover 1, for example, 90°, the first light therapy plate 21 protrudes high from the upper surface of the cover 1, exposing the first light-emitting surface 211 and preventing the treatment light from being blocked by the cover 1.

[0028] Reference Figure 1 and Figure 2 The second light therapy plate 22 is slidably connected to the first light therapy plate 21, allowing the second light therapy plate 22 to slide between its retracted position (stacked over the first light therapy plate 21) and its extended position (the second light-emitting surface 221 extending outwards from the first light therapy plate 21). The second light therapy plate 22 and the first light therapy plate 21 form a sliding fit, and its overall size can be set similar to that of the first light therapy plate 21, allowing it to be tightly stacked on top of the first light therapy plate 21 during storage, reducing the vertical dimension. When needed, the second light therapy plate 22 is slid to its extended position, extending the second light-emitting surface 221 outwards from the first light therapy plate 21, working together with the first light-emitting surface 211 to obtain a sufficiently large light-emitting treatment range.

[0029] Phototherapy component 2 has both a stored state and a working state; In the stowed state, the first light therapy plate 21 is in the folded position, and the second light therapy plate 22 is in the retracted position. In the stowed state, the first light therapy plate 21 is rotated to the folded position close to the cover 1 through a rotating connection with the cover 1, while the second light therapy plate 22 is retracted and stacked on top of the first light therapy plate 21 through a sliding connection with the first light therapy plate 21. At this time, the volume of the entire physiotherapy cover is minimized as much as possible, making it convenient to carry or store.

[0030] Reference Figure 2 and Figure 5 In its working state, the first light therapy plate 21 is in the unfolded position, and the second light therapy plate 22 is in the extended position. The first light-emitting surface 211 and the second light-emitting surface 221 together form an extended irradiation surface. When needed, first remove the cover 1 from the container 8, take out the skincare product from the container 8 for use, and then close the cover 1. Then, rotate the first light therapy plate 21 from the folded position to the unfolded position at an angle to the cover 1. This angle can be adjusted according to the treatment needs to ensure that the light-emitting surface is directly facing the target area. Next, push the second light therapy plate 22 so that it slides from the retracted position to the extended position, with the second light-emitting surface 221 extending beyond the first light therapy plate 21. At this time, the first light-emitting surface 211 and the second light-emitting surface 221, which face the same direction, are combined to form an extended irradiation surface, which can cover a large area without moving the instrument. This simplifies the operation, ensures the uniformity of irradiation, and improves the efficiency and experience of the treatment.

[0031] Reference Figure 1 and Figure 2 The cover 1 has a receiving groove 11 on the side away from the container 8. One end of the first phototherapy plate 21 is pivotally connected to the receiving groove 11 through the horizontal shaft 7 so that it sinks into the receiving groove 11 when in the folded position.

[0032] Reference Figure 2 The receiving groove 11 is located on the side of the cover 1 facing away from the container 8, specifically on the upper surface of the cover 1 in some embodiments. The overall cross-sectional shape of the receiving groove 11 can be L-shaped, that is, it includes a bottom wall, a first groove wall 111 and two opposing second groove walls. The two ends of the first groove wall 111 are respectively connected to the two second groove walls, and the upper end is a groove. The side facing the first groove wall 111 is also a groove, so as to facilitate the sliding extension of the second light therapy plate 22 and avoid interference between the second light therapy plate 22 and the first groove wall 111, which would prevent the first light therapy plate 21 from rotating upward. The two second groove walls are provided with shaft holes, and a horizontal shaft 7 is inserted into the shaft holes and passes through the first light therapy plate 21, so that the first light therapy plate 21 can rotate around the horizontal shaft 7. The depth of the receiving groove 11 can accommodate the pivot end of the first light therapy plate 21, and the width is slightly larger than the thickness of the first light therapy plate 21, ensuring that the first light therapy plate 21 can smoothly sink into the groove.

[0033] The cooperation between the receiving groove 11 and the horizontal axis 7 makes the storage and unfolding of the first light therapy plate 21 more practical. When it is necessary to store the physiotherapy cover, the first light therapy plate 21 is rotated around the horizontal axis 7 towards the receiving groove 11 until the first light therapy plate 21 is completely submerged in the receiving groove 11 without protruding outwards, further compressing the storage volume of the physiotherapy cover, making storage more convenient, and preventing the first light therapy plate 21 from being accidentally damaged by collisions due to protrusion. In use, the user only needs to turn the free end of the first light therapy plate 21, and the first light therapy plate 21 will rotate out of the receiving groove 11 around the horizontal axis 7 until it is adjusted to the unfolded position at a suitable angle with the cover body 1.

[0034] Reference Figure 1 and Figure 2 The depth of the receiving groove 11 is adapted to the thickness of the phototherapy component 2 in its stored state, so that when the phototherapy component 2 is stored, both the first phototherapy plate 21 and the second phototherapy plate 22 are embedded in the receiving groove 11. The depth of the receiving groove 11 matches the overall thickness of the first phototherapy plate 21 and the second phototherapy plate 22 after stacking, to ensure that the phototherapy component 2 can be fully embedded when stored. For example, if the thickness of the first phototherapy plate 21 is 6mm and the thickness of the second phototherapy plate 22 is 5mm, the thickness of the two after stacking is 11mm, then the depth of the receiving groove 11 is also 11mm. Since the depth of the receiving groove 11 is adapted to the thickness after stacking, the first phototherapy plate 21 and the second phototherapy plate 22 will sink into the receiving groove 11 together, without any partial protrusion. After the phototherapy component 2 is embedded in the receiving slot, its outer surface remains basically flush with the surface of the cover 1. The entire treatment cover is like an ordinary cover without protrusions, making the storage volume of the treatment cover more compact and preventing it from snagging on clothing when placed in a cosmetic bag or pocket. At the same time, the first phototherapy plate 21 and the second phototherapy plate 22 are embedded together in the receiving slot 11 and are limited by the slot wall, avoiding wear and tear on the components caused by shaking during carrying and extending the life of the device.

[0035] Reference Figure 4 and Figure 5 In some preferred embodiments, the unfoldable physiotherapy cover also includes a magnetic suction assembly 3, which includes a first magnetic suction element 31 and a second magnetic suction element 32.

[0036] The first magnetic attractor 31 is located on the side of the first phototherapy plate 21 opposite to the first light-emitting surface 211, that is, the side that faces outwards during phototherapy, does not contact the skin, and is close to it. The first magnetic attractor 31 can be a neodymium iron boron strong magnet or a ferrite magnet. The first magnetic attractor 31 can be glued or embedded in a preset groove in the first phototherapy plate 21, or it can be set inside the first phototherapy plate 21.

[0037] The second magnetic attractor 32 is disposed on the first groove wall 111 of the receiving groove 11. The second magnetic attractor 32 is disposed on the first groove wall 111 of the receiving groove 11, meaning that when the first phototherapy plate 21 is rotated to the unfolded position, the side of it facing away from the first light-emitting surface 211 will abut against the first groove wall 111. The shape of the second magnetic attractor 32 matches that of the first magnetic attractor 31. If the first magnetic attractor 31 is sheet-shaped, the second magnetic attractor 32 will also be sheet-shaped of a corresponding size. The material can be the same as that of the first magnetic attractor 31, or it can be a metal part that can be attracted by a magnet, such as an iron sheet or a nickel sheet. The second magnetic attractor 32 can be fixed to the first groove wall 111 by adhesive or embedding to ensure that it will not fall off during the adsorption process.

[0038] When the first light therapy plate 21 is rotated to the unfolded position, the side of the first light therapy plate 21 facing away from the first light-emitting surface 211 is against the first groove wall 111, and the second magnetic suction member 32 is attracted and fixed to the first magnetic suction member 31 to keep the first light therapy plate 21 in the unfolded position. When the user needs to use the physiotherapy cover, the second light therapy plate 22 is first pushed out to the extended position to avoid the second light therapy plate 22 affecting the first light therapy plate 21's rotation and proximity to the first groove wall 111. Then, the first light therapy plate 21 is rotated out of the receiving groove 11 around the horizontal axis 7. As the first light therapy plate 21 rotates, its side facing away from the first light-emitting surface 211 gradually moves closer to the first groove wall 111 of the receiving groove 11. When the first light therapy plate 21 is rotated to the unfolded position, the side of the first light therapy plate 21 is just against the first groove wall 111, at which point the first magnetic suction member 31 and the second magnetic suction member 32 are just aligned and attracted to each other. This magnetic attraction firmly secures the first light therapy plate 21 in its unfolded position, preventing it from rotating due to slight hand movements or the weight of the treatment cover itself. When unfolding, the user simply rotates the first light therapy plate 21 until it is flush against the first groove wall 111; no further adjustment is required. During light therapy, even if the first light therapy plate 21 is accidentally touched, the magnetic attraction ensures its stability in the unfolded position, maintaining the irradiation angle and distance between the first light-emitting surface 211 and the second light-emitting surface 221, thus enhancing the light therapy effect. When storage is required, the user simply applies slight force to the first light therapy plate 21, overcoming the magnetic attraction, and rotates it back into the receiving groove 11, making the operation very convenient.

[0039] Reference Figure 4 and Figure 5 The unfoldable physiotherapy cover also includes a detection element 4 and a control circuit board 5.

[0040] The detection element 4 is disposed on the first phototherapy plate 21 and is used to generate a trigger signal when the first magnetic attractor 31 and the second magnetic attractor 32 are attracted together. The detection element 4 is used to sense the magnetic attraction state and send a signal. It is fixedly installed inside the first phototherapy plate 21, for example, in a position close to the first magnetic attractor 31, while maintaining a certain distance from the first magnetic attractor 31 to avoid magnetic interference. The detection element 4 can be a Hall sensor, a reed switch, etc.

[0041] The control circuit board 5 is electrically connected to the detection element 4 and the phototherapy assembly 2. Upon receiving a trigger signal, it drives the first light-emitting surface 211 and the second light-emitting surface 221 to emit therapeutic light. The control circuit board 5 is specifically a PCB printed circuit board, on which a microcontroller, driver chip, power management module, etc., are mounted. The control circuit board 5 is installed inside the cavity of the first phototherapy plate 21 and fixed by screws or brackets. The trigger signal is an electrical signal emitted by the detection element 4, specifically a high-level or low-level signal. For example, when the detection element 4 does not detect effective magnetic attraction, it maintains a low-level output; when the first magnetic attraction member 31 and the second magnetic attraction member 32 are fully attracted, the detection element 4 detects the change in the magnetic field and switches to output a high-level signal. Upon receiving this signal, the control circuit board 5 activates the phototherapy function of the phototherapy assembly 2, causing the first light-emitting surface 211 and the second light-emitting surface 221 to emit therapeutic light. To turn it off, simply rotate the first phototherapy plate 21 to separate the first magnetic attraction member 31 and the second magnetic attraction member 32; the high-level signal changes to a low-level signal, automatically stopping the phototherapy function and stopping the emission of therapeutic light. The switching on and off of the light is intelligently controlled by the control circuit board 5 based on the trigger signal, without any additional manual operation.

[0042] Reference Figure 4 The detection element 4 is a Hall sensor, which is positioned adjacent to the first magnetic chuck 31 and uses the magnetic field of the first magnetic chuck 31 as the detection object. When the first magnetic chuck 31 and the second magnetic chuck 32 are attracted, the Hall sensor emits a trigger signal due to the change in magnetic field strength. The Hall sensor is small in size and can be easily embedded in the narrow space of the first phototherapy plate 21. The magnetic field of the first magnetic chuck 31 is the detection object of the Hall sensor, and its magnetic field strength is related to the material and size of the magnetic chuck.

[0043] When the user rotates the first light therapy panel 21 to the unfolded position, the first magnetic clasp 31 gradually approaches the second magnetic clasp 32, and the two begin to generate a magnetic attraction. Before the attraction, the Hall sensor can only detect the magnetic field of the first magnetic clasp 31, which is relatively weak; as the attraction is completed, the magnetic fields of the first magnetic clasp 31 and the second magnetic clasp 32 are superimposed, and the magnetic field strength at the location of the Hall sensor will instantly jump to a preset threshold, thereby generating a trigger signal to start the light therapy function.

[0044] Reference Figure 3 and Figure 6The first phototherapy plate 21 has grooves 212 on both sides, and the second phototherapy plate 22 has sliders 222 on both sides that are adapted to the shape of the grooves 212. The grooves 212 extend along the sliding direction of the second phototherapy plate 22, and their specific length corresponds to the extension and retraction of the second phototherapy plate 22. The shape of the sliders 222 is adapted to the shape of the grooves 212, so that they can slide along the grooves 212. Specifically, the cross-sectional shape of the grooves 212 is T-shaped or L-shaped, and the sliders 222 are also correspondingly set to T-shaped or L-shaped, which can both slide smoothly and have an anti-detachment effect.

[0045] Reference Figure 6 The unfoldable physiotherapy cover also includes a positioning structure 6, which includes a rolling element 61, an elastic element 62, a first positioning groove 63, and a second positioning groove 64.

[0046] The slider 222 has a mounting hole 223, and the rolling element 61 is located within the mounting hole 223 and can move along the axis of the mounting hole 223. The rolling element 61 can be spherical or cylindrical. It is installed in the mounting hole 223 of the slider 222 and can move freely along the axis of the mounting hole 223. The part protruding from the mounting hole 223 can form a tight fit with the two positioning grooves. At the same time, the rolling characteristics can reduce the frictional resistance when the second phototherapy plate 22 slides, making the telescopic operation smoother. The mounting hole 223 can be cylindrical, and its depth is slightly greater than the sum of the diameter of the rolling element 61 and the compressed length of the elastic element 62.

[0047] The elastic element 62 is disposed in the mounting hole 223 and pushes the rolling element 61 outward from the mounting hole 223. The elastic element 62 can be a small compression spring or an elastic rubber column. When it is under pressure, its restoring force will push the rolling element 61 outward from the mounting hole 223, so that the rolling element 61 always maintains the tendency to contact the groove wall of the slide groove 212. When it encounters the positioning groove, it can push the rolling element 61 into the positioning groove to achieve positioning.

[0048] The first positioning groove 63 is located on the wall of the slide groove 212. When the second phototherapy plate 22 slides to the retracted position, the rolling element 61 protrudes from the mounting hole 223 and embeds into the first positioning groove 63. The position of the first positioning groove 63 corresponds to the retracted position of the second phototherapy plate 22, that is, when the second phototherapy plate 22 is completely stacked on the first phototherapy plate 21, the mounting hole 223 on the slider 222 is just aligned with the first positioning groove 63. The first positioning groove 63 can be a hemispherical groove.

[0049] The second positioning groove 64 is provided on the groove wall of the slide groove 212. When the second phototherapy plate 22 slides to the extended position, the rolling element 61 protrudes from the mounting hole 223 and is embedded in the second positioning groove 64. The position of the second positioning groove 64 corresponds to the extended position of the second phototherapy plate 22, that is, when the second phototherapy plate 22 is fully extended from the first phototherapy plate 21, the mounting hole 223 and the position of the second positioning groove 64 coincide. The second positioning groove 64 can be a hemispherical groove.

[0050] When the user pushes the second light therapy plate 22 to the retracted position, the slider 222 drives the rolling element 61 to move along the groove wall of the slide groove 212. At this time, the rolling element 61 is squeezed by the groove wall, overcoming the elastic force of the elastic element 62 and contracting into the mounting hole 223, and the elastic element 62 is in a compressed state. When the second light therapy plate 22 slides to the fully retracted position, the mounting hole 223 is aligned with the first positioning groove 63, the squeezing force of the groove wall on the rolling element 61 disappears, and the elastic element 62 pushes the rolling element 61 out of the hole, causing the rolling element 61 to partially protrude and embed into the first positioning groove 63, and the second light therapy plate 22 is fixed in the retracted position. When it is necessary to unfold the second light therapy plate 22, the user pulls the second light therapy plate 22 outward, causing the rolling element 61 to disengage from the first positioning groove 63 and compress the elastic element 62 again. As the second light therapy plate 22 continues to slide, the rolling element 61 rolls along the groove wall of the slide groove 212. When the second phototherapy plate 22 reaches the extended position, the mounting hole 223 aligns with the second positioning groove 64, and the elastic member 62 pushes the rolling member 61 to embed into the second positioning groove 64, thus fixing the position of the second phototherapy plate 22. This positioning method allows the second phototherapy plate 22 to remain stably in both positions, preventing displacement due to vibration or contact during phototherapy.

[0051] Reference Figure 6 The rolling element 61 is a ball bearing, and the outer end of the mounting hole 223 is provided with a constriction 112, the inner diameter of which is smaller than the diameter of the ball bearing. The constriction 112 is located on the side of the slider 222 facing the groove 212, and can be formed into an annular protrusion by extrusion, injection molding, or machining to reduce the inner diameter of the hole. This design eliminates the need for additional limiting components, preventing the ball bearing from falling out while ensuring that it has sufficient protrusion to fit into the positioning hole, simplifying the structure and reducing assembly difficulty.

[0052] Reference Figure 4 and Figure 5 A battery 215 is installed inside the first light therapy plate 21. The battery 215 is a rechargeable battery and is installed in the cavity of the first light therapy plate 21. The battery 215 is connected to the control circuit board 5 via wires to power the lamp board in the first light therapy plate 21. The first light therapy plate 21 may also be provided with a charging interface to replenish the power of the battery 215. This interface may be located on the side or end of the first light therapy plate 21 and can be a Micro-USB or Type-C interface.

[0053] Reference Figure 7The first phototherapy plate 21 has a strip-shaped clearance groove 213 and a conductive sheet 214 on the side facing the second phototherapy plate 22. The strip-shaped clearance groove 213 is parallel to the sliding direction of the second phototherapy plate 22. The conductive sheet 214 protrudes from one end of the bottom wall of the clearance groove and is electrically connected to the battery 215. The length of the strip-shaped clearance groove 213 can be slightly greater than the sliding stroke of the second phototherapy plate 22 to ensure that the elastic conductive head 224 can move within the groove throughout its entire movement. The cross-section of the strip-shaped clearance groove 213 can be U-shaped. The second phototherapy plate 22 is located at one end of the clearance groove, near the position it ultimately reaches when it extends outward. The conductive sheet 214 can be made of copper or gold-plated metal and is directly electrically connected to the battery 215 inside the first phototherapy plate 21 via a wire. Preferably, the surface of the conductive sheet 214 has protrusions to enhance the reliability of contact with the elastic conductive head 224.

[0054] The second phototherapy plate 22 is equipped with an elastic conductive head 224, which protrudes and extends into the clearance groove. The elastic conductive head 224 is the power receiving element of the second phototherapy plate 22, installed on the side of the second phototherapy plate 22 facing the first phototherapy plate 21, corresponding to the position of the strip-shaped clearance groove 213. The elastic conductive head 224 is made of a highly conductive elastic material, such as a phosphor bronze spring sheet with conductive contacts, or a metal probe with an integrated spring, and has a certain amount of flexibility. The conductive head protrudes from the surface of the second phototherapy plate 22, just enough to extend into the strip-shaped clearance groove 213, with a gap between the protrusion height and the bottom wall of the clearance groove to avoid affecting sliding. One side of the conductive sheet 214 is a guide slope to facilitate the sliding guidance of the elastic conductive head 224 to the upper end face of the conductive sheet 214 for continuous contact.

[0055] When the second phototherapy plate 22 slides from the retracted position to the extended position, the elastic conductive head 224 moves within the clearance groove and contacts the conductive sheet 214 upon reaching the extended position, thereby supplying power to the second phototherapy plate 22. When the user pushes the second phototherapy plate 22 to slide outward from the retracted position, the elastic conductive head 224 on the second phototherapy plate 22 moves synchronously within the strip-shaped clearance groove 213 of the first phototherapy plate 21. At this time, the elastic conductive head 224 does not contact the bottom wall of the groove, leaving a gap to avoid affecting the sliding, and is not connected to the conductive sheet 214, so the second phototherapy plate 22 is in a de-energized state. As the second phototherapy plate 22 continues to slide, the elastic conductive head 224 moves smoothly along the clearance groove until the second phototherapy plate 22 fully reaches the extended position, at which point the elastic conductive head 224 precisely aligns with the conductive sheet 214 protruding from the end of the clearance groove. The elasticity of the flexible conductive head 224 ensures it presses firmly against the conductive sheet 214, forming a reliable electrical contact. The battery 215 inside the first phototherapy plate 21 then forms a power supply circuit through the conductive sheet 214 and the flexible conductive head 224, transmitting power to the lamp panel of the second phototherapy plate 22. When the control circuit board 5 activates the phototherapy function, the second light-emitting surface 221 of the second phototherapy plate 22 emits light synchronously with the first light-emitting surface 211 of the first phototherapy plate 21 under electrical drive. This design only supplies power to the second phototherapy plate 22 when it is fully extended and the irradiation range needs to be expanded, saving energy and avoiding accidental power consumption when the second phototherapy plate 22 is idle. At the same time, the strip-shaped clearance groove 213 provides a stable movement path and protection for the conductive head, preventing the conductive components from being exposed to the outside and becoming contaminated or damaged. Combined with the elastic contact structure, it ensures the stability and durability of the power supply connection, making the equipment more efficient and reliable.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
