[0040] In combination Figures 1 to 3 The light therapy hairpin 10 provided by the application comprises a pin body 100, a control board 200, a lamp plate 300 and a light-transmitting shell 400. One end of the pin body 100 is provided with a mounting cavity 101 and a light outlet hole 102, and the light outlet hole 102 is in communication with the mounting cavity 101. The design of the pin body 100 makes the light therapy hairpin 10 convenient to carry and handheld. The light-transmitting shell 400 is mounted on the pin body 100 and covers the light outlet hole 102, the control board 200 and the lamp plate 300 are both mounted in the mounting cavity 101, the control board 200 is electrically connected with the lamp plate 300, and the light emitted by the lamp plate 300 is emitted outward through the light-transmitting shell 400.

[0041] The light-transmitting shell 400 not only allows the light emitted by the lamp plate 300 to pass through to perform light therapy on the human skin, but also can contact and massage the human skin, further improving the skin treatment effect and enriching the function of the light therapy hairpin 10. The light-transmitting shell 400 separates the lamp plate 300 and the human skin, ensuring that the light emitted by the lamp plate 300 can all pass through the light-transmitting shell 400 for light therapy. The thickness of the light-transmitting shell 400 determines the distance between the lamp plate 300 and the human skin, and the light therapy distance is stable and controllable. Compared with general light therapy devices, the light therapy hairpin 10 provided by the application adopts a hairpin structure, which is beautiful and convenient to carry.

[0042] In some embodiments, in combination Figure 2 And Figure 3 The light outlet hole 102 penetrates the pin body 100, the number of the light-transmitting shell 400 is two, the two light-transmitting shells 400 cover two ends of the light outlet hole 102 respectively, and the lamp plate 300 is located between the two light-transmitting shells 400. The light emitted by the lamp plate 300 can pass through the two light-transmitting shells 400 and be irradiated from both sides of the pin body 100 respectively, and the user can select any side for light therapy according to his own needs or comfort.

[0043] Specifically, the light therapy hairpin 10 is placed on the cheek, chin or joint to realize massage and light therapy on the skin on both sides of the human body.

[0044] Specifically, the light-emitting hole 102 penetrates the hairpin body 100 along the thickness direction of the hairpin body 100, shortens the light-emitting distance, reduces the reflection and scattering of light in the hairpin body 100, and thus improves the propagation efficiency and utilization of light. In addition, the light-emitting hole 102 penetrates the hairpin body 100 in the thickness direction, has a small hole depth, a small processing amount, and a small effect on the strength of the hairpin body 100.

[0045] In some embodiments, in combination with Figure 3 and Figure 4 The light-transmitting shell 400 is a jade massage block, which is used for massaging human skin. The jade massage block not only allows the light emitted by the lamp panel 300 to pass through for phototherapy, but also has a hardness and shape design suitable for massaging human skin. The jade has a natural cold compress feature that can help reduce skin temperature and relieve inflammation and swelling when in contact with human skin. During phototherapy, the cold compress effect of the jade massage block can further enhance the skin treatment effect, such as reducing swelling and soothing sensitive skin. The massage effect of the jade massage block can promote blood circulation and increase skin metabolism. Combined with the phototherapy effect, it can better promote the regeneration and repair of skin cells and improve skin quality.

[0046] Optionally, the material of the jade massage block can be quartz, nephrite, or jadeite, etc. The jade massage block is optionally rich in metals or minerals.

[0047] For example, the light-transmitting shell 400 is a light-transmitting marble shell. On the one hand, marble has a lower cost than jadeite, nephrite, and jade, which is conducive to reducing the manufacturing cost of the phototherapy hairpin 10 and facilitating the promotion of the product. On the other hand, marble has high compressive strength and wear resistance, which improves the service life of the product and broadens the application scenarios of the product.

[0048] It can be understood that in other embodiments, the light-transmitting shell 400 can be a metal block, such as a hollow silver block, a hollow copper block, a hollow aluminum oxide block, or a light-transmitting silica gel block, a glass lens, a hollow ceramic block, without being limited to the above.

[0049] In some embodiments, in combination with Figure 3 and Figure 4 The light-transmitting shell 400 has a skin contact surface 401 exposed to the hairpin body 100, thereby more effectively delivering phototherapy effect and massage touch. As a medium for light transmission, the skin contact surface 401 can ensure that the light is more concentrated on the skin, increase the contact area between the light-transmitting shell 400 and the skin, and reduce the scattering and loss of light.

[0050] Specifically, the skin surface 401 is an arc surface that protrudes outward away from the lamp panel 300. Since the arc surface protrudes outward, it can form a larger contact area with the skin. At the same time, the arc surface allows the light-transmitting shell 400 to provide a better massage touch when it contacts the skin. The arc design allows the light-transmitting shell 400 to better adapt to the skin of different parts of the human body. For example, the skin shape and curvature of the chin, joints and other parts are different, and the light-transmitting shell 400 with an arc surface can better contact these parts, ensuring the maximization of light therapy and massage effect.

[0051] In some embodiments, in combination Figure 3 and Figure 4 , the light-transmitting shell 400 has a mounting surface 402 close to the lamp panel 300, which is used to be mounted with the stem 100. The mounting eliminates the gap between the light-transmitting shell 400 and the stem 100, reduces the leakage of light at the connection between the light-transmitting shell 400 and the stem 100, and increases the accumulation of the mounting surface 402, thereby improving the mounting strength.

[0052] In one of the embodiments, the mounting surface 402 is a flat surface, which realizes a larger contact area between the light-transmitting shell 400 and the stem 100, thereby improving the stability of the mounting.

[0053] In one of the embodiments, the lamp panel 300 includes a substrate and LED lamp beads arranged on the substrate, and the substrate is electrically connected with the control panel 200, which controls the light-emitting of the LED lamp beads through the substrate. Optionally, the number of LED lamp beads can be multiple, and the multiple LED lamp beads are arranged on the substrate at intervals to improve the light therapy effect.

[0054] Specifically, the substrate is provided with LED lamp beads on both sides to reduce the light therapy dead angle and make the light therapy more uniform and effective. Optionally, the parameters of the LED lamp beads on different sides of the substrate are not completely the same to meet different application scenarios and user light therapy needs. The parameters of the LED lamp beads include the number, arrangement, rated power and light-emitting wavelength.

[0055] In one of the embodiments, the light emitted by the lamp panel 300 includes red light and blue light, and the combination of red light and blue light can produce a synergistic effect to enhance the light therapy effect. Red light promotes cell metabolism and wound healing, while blue light kills bacteria and inhibits sebaceous gland secretion, which together improve the skin condition.

[0056] Optionally, the wavelength of the red light is 630 nm, and the wavelength of the blue light is 415 nm. The irradiation of the red light with a wavelength of 630 nm can enhance the catalase activity in the mitochondria, improve the metabolic activity of the cells, promote the proliferation of the fibroblasts and the endothelial cells, increase the metabolism of the cells, and promote the synthesis of the cells. The irradiation of the blue light with a wavelength of 415 nm can cause the endogenous porphyrin and coproporphyrin in the anaerobic P. acnes to undergo photochemical reaction to generate singlet oxygen, thereby killing the bacteria and inhibiting the secretion of the sebaceous glands. Moreover, the total optical power is in the range of 20 mW / cm 2 to 40 mW / cm 2, and the irradiation intensity of the red light and the blue light is moderate, which can ensure the phototherapy effect and avoid excessive damage to the skin. The total optical power of the red light and the blue light can be specifically selected as 20 mW / cm 2, 25 mW / cm 2, 30 mW / cm 2, 35 mW / cm 2, or 40 mW / cm 2.

[0057] In some embodiments, in conjunction with Figure 2 and Figure 3 The zither body 100 has a limiting baffle 103 arranged around the light outlet hole 102, and the limiting baffle 103 abuts against the side wall of the light-transmitting shell 400. The limiting baffle 103 can ensure that the light-transmitting shell 400 is in the correct position during installation and prevent it from moving radially due to external force or manufacturing error.

[0058] In one of the embodiments, the limiting baffle 103 has a notch 104 to expose part of the side wall of the light-transmitting shell 400. On the one hand, it allows part of the side wall of the light-transmitting shell 400 to be directly exposed to the outside, thereby achieving phototherapy on the skin located on the side wall of the light-transmitting shell 400. On the other hand, it facilitates the assembly and disassembly of the light-transmitting shell 400 through the notch 104.

[0059] In one of the embodiments, the notch 104 corresponds to a central angle of 20° to 100°. For example, the light outlet hole 102 is a circular hole, and the notch 104 corresponds to a central angle of 20° to 100° formed by the center of the circular hole. On the one hand, the exit angle of the notch 104 is greater than or equal to 20°, which ensures that it can cover a certain range of phototherapy area. On the other hand, the central angle occupied by the notch 104 is less than or equal to 100°, which avoids weakening the limiting effect of the limiting baffle 103 on the light-transmitting shell 400.

[0060] In some embodiments, the light-transmitting shell 400 is provided with a temperature adjusting member electrically connected to the control board 200, which can heat or cool the light-transmitting shell 400 to achieve the function of hot or cold compress on the human skin. Hot compress can promote blood circulation, and has the effects of anti-inflammation, cold prevention, fatigue reduction, and increase of the extensibility of human tissues, and is suitable for chronic injuries such as arthritis and lumbar muscle strain. Cold compress can constrict blood vessels and reduce the exudation of capillary blood, and has the effects of reducing swelling, analgesia, anesthesia, and preventing inflammation, and is suitable for acute injuries such as sprains and swelling. The light therapy hairpin 10 can provide personalized treatment plans for different diseases by realizing the hot or cold compress function of the light-transmitting shell 400 through the temperature adjusting member, thereby enhancing the treatment effect.

[0061] Alternatively, the temperature adjusting member can be a heating sheet or a cold source pad.

[0062] In some embodiments, the light-transmitting shell 400 is mounted on the pin body 100 by an elastic member, and has a certain elasticity and adaptability, so that it can closely fit the human skin of different shapes and curvatures. The elastic effect of the elastic member enables the light-transmitting shell 400 to generate a certain pressure when contacting the skin, thereby playing a massaging role.

[0063] In some embodiments, the light-transmitting shell 400 is mounted on the pin body 100 by a ball joint, so that the light-transmitting shell 400 can freely rotate to adapt to the human skin of different angles and curves, and the user can adjust the position and angle of the light-transmitting shell 400 as needed.

[0064] In some embodiments, in combination with Figure 3 , Figure 5 and Figure 6 , the light therapy hairpin 10 further comprises a battery 510 and a magnetic electrode 520, and the end of the shell body away from the light outlet hole 102 has a receiving cavity, the battery 510 is mounted in the receiving cavity, the battery 510 is electrically connected to the control board 200, the pin body 100 has a charging hole 106, one end of the magnetic electrode 520 is electrically connected to the control board 200, and the other end of the magnetic electrode 520 extends into the charging hole 106. The built-in battery 510 enables the light therapy hairpin 10 to work without relying on external power supply, greatly improving the convenience of use. The user only needs to place the charging plug 20 close to the charging hole 106 of the light therapy hairpin 10 to realize automatic adsorption and charging without complicated plugging and unplugging operations, thereby improving the charging efficiency. Correspondingly, the charging plug 20 has a charging terminal that is magnetically attracted to the magnetic electrode 520.

[0065] Alternatively, the capacity of the battery 510 is 50mAh-70mAh, and the volume is small, which is convenient for the user to carry and use the light therapy hairpin 10, and can last for more than 3 hours. For example, the capacity of the battery 510 is 50mAh, 55mAh, 60mAh, 65mAh or 70mAh.

[0066] In one embodiment, the light therapy hairpin 10 further comprises an electric quantity indicator light, which is installed on the pin body 100 and electrically connected with the control board 200, and is used to indicate the electric quantity of the battery 510. For example, in the working state, when the electric quantity of the battery 510 is greater than or equal to 20% of the rated electric quantity, the electric quantity indicator light is always on, and when the electric quantity of the battery 510 is less than 20% of the rated electric quantity, the electric quantity indicator light flashes. There is no need to set multiple colors of light, which simplifies the structure and control difficulty of the light therapy hairpin 10. The flashing frequency can be selected as 1 Hz. The color of the light emitted by the electric quantity indicator light can be selected as green, purple or white, etc., which is not limited here.

[0067] In one of the embodiments, in combination with Figure 5 , Figure 6 and Figure 7 , the magnetic electrode 520 has a limiting step 521, which abuts against the inner wall of the pin body 100, so that the magnetic electrode 520 partially extends into the charging hole 106 and partially locates in the installation cavity 101. Among them, the limiting step 521 abuts against the inner wall of the pin body 100, which ensures the stable position of the magnetic electrode 520 in the charging hole 106 and prevents it from shaking or falling off.

[0068] In one of the embodiments, in combination with Figure 3 and Figure 7 , the installation cavity 101 is provided with an installation groove 107, the control board 200 is limitedly installed in the installation groove 107, and the groove bottom of the installation groove 107 is provided with the charging hole 106. Based on this, on the one hand, the distance between the control board 200 and the magnetic electrode 520 is shortened, the loss of current in the transmission process is reduced, and the conduction efficiency is improved, and on the other hand, by limiting the installation of the control board 200 in the installation groove 107 and setting the charging hole 106 at the groove bottom, the space in the installation cavity 101 is more effectively utilized, which helps to reduce the overall size of the light therapy hairpin 10 and improve the portability.

[0069] In one embodiment, in combination with Figure 1 and Figure 3 , the light therapy hairpin 10 further comprises a control switch 530, which is electrically connected with the control board 200 and exposed to the pin body 100, so as to facilitate the user to control the working state of the light therapy hairpin 10.

[0070] Specifically, the number of the control switch 530 is one, which simplifies the operation and improves the user convenience. The light therapy hairpin 10 has only two operating states, i.e., the working state and the shutdown state. The control switch 530 is configured to switch the operating state of the light therapy hairpin 10 when pressed. For example, the user presses the control switch 530, and the light therapy hairpin 10 enters the working state. The user presses the control switch 530 again, and the light therapy hairpin 10 enters the shutdown state. To avoid misoperation, the control switch 530 switches the operating state of the light therapy hairpin 10 after being pressed for more than a first preset time. For example, the user presses the control switch 530 for 1.5 s, and the light therapy hairpin 10 enters the working state. The user presses the control switch 530 again for 1.5 s, and the light therapy hairpin 10 enters the shutdown state.

[0071] In one embodiment, to avoid excessive light therapy and simplify the operation, the light therapy hairpin 10 enters the shutdown state after the lamp panel 300 works for more than a second preset time. The second preset time can be 2 min, 3 min, 5 min, or 10 min. In some embodiments, the material of the pin body 100 is aluminum alloy, plastic, or iron alloy, which is not limited herein. Alternatively, the pin body 100 is an aluminum alloy shell, which has the characteristics of low density and high strength, so that the pin body 100 is light and durable.

[0072] In some embodiments, the pin body 100 has a frosted surface, which not only changes the texture of the surface of the pin body 100 and improves the comfort of the user's hand, but also increases the anti-fingerprint and anti-scratching performance of the pin body 100, improves the durability and aesthetics of the pin body 100. Alternatively, the pin body 100 is processed by a fine sand spraying process to obtain the frosted surface.

[0073] In some embodiments, the outer surface of the pin body 100 is provided with an oxidation layer, which avoids the oxidation of the metal material of the pin body 100, improves the service life, and widens the use conditions. Alternatively, the outer surface of the pin body 100 is subjected to an anodizing treatment. Alternatively, the outer surface of the pin body 100 is first processed by a fine sand spraying process to obtain a frosted surface, and then an oxidation layer is processed on the frosted surface by an anodizing process.

[0074] In some embodiments, in combination with Figure 1 , Figure 6 and Figure 7 , the pin body 100 includes a rod portion 110 and a head portion 120, the rod portion 110 and the head portion 120 are detachably connected, the head portion 120 has a mounting cavity 101 and a light outlet hole 102, the diameter of the light outlet hole 102 is greater than the diameter of the rod portion 110, and the control panel 200 and the lamp panel 300 are mounted on the head portion 120. The diameter of the rod portion 110 is small, so that the overall volume of the light therapy hairpin 10 is reduced, which is more convenient to carry and hold. The outer diameter of the head portion 120 is large, which provides sufficient mounting space for the lamp panel 300 and the control panel 200, increases the light therapy area, and improves the performance of the light therapy hairpin 10.

[0075] Optionally, the inner space of the rod part 110 is communicated with the mounting cavity 101 of the head part 120. The battery 510 is mounted in the inner space of the rod part 110. The battery 510 is in the shape of a cylinder, which is adapted to the size of the inner space of the rod part 110.
