[0036] Refer to the attached Figures 1-5 As shown, a hydrocolloid phototherapy acne patch includes:

[0037] A housing 100, with a cavity provided inside the housing 100;

[0038] A power source 200, installed in the cavity of the housing 100;

[0039] A PCB board 300, installed in the cavity of the housing 100 and electrically connected to the power source 200, and a plurality of phototherapy lamp beads 400 are provided on the surface of the PCB board 300;

[0040] A light guide member 500, installed at the opening of the cavity;

[0041] A hydrocolloid dressing 600, adhered to the surface of the light guide member 500, and a skin care essence is provided inside the hydrocolloid dressing 600;

[0042] Wherein, a light condensing glue 410 is provided on the surface of the PCB board 300, and the light condensing glue 410 is used to adjust the light path.

[0043] The design aims to combine phototherapy technology with skin care essence, and through the synergistic effect of the built-in phototherapy LED lamp beads and the hydrocolloid dressing 600, provide an efficient, portable and comprehensive acne care solution. The specific wavelength light emitted by the phototherapy lamp beads 400 can treat acne, while the skin care essence in the hydrocolloid dressing 600 helps nourish and repair the skin. This design aims to not only effectively treat acne, but also improve the overall skin condition and enhance the user experience.

[0044] When the hydrocolloid phototherapy acne patch is applied to the skin surface, the power source 200 provides power for the phototherapy LED lamp beads on the PCB board 300, so that the lamp beads emit specific wavelength light such as red light, blue light and near-infrared light. Red light helps cell regeneration and blood circulation, blue light can eliminate acne pathogenic bacteria, and near-infrared light can penetrate deep into the skin to reduce inflammation. These lights are evenly distributed on the skin surface through the light guide member 500, so as to achieve the purpose of treating acne.

[0045] The light - concentrating glue 410 located on the surface of the PCB board 300 changes the light path, makes the light concentrate on the target area, prevents excessive light scattering, and improves the efficiency of phototherapy. The setting of the light - concentrating glue 410 ensures that the light can effectively cover the pimples and the surrounding skin area, enhancing the phototherapy effect.

[0046] The light - guiding part 500 is installed at the opening of the housing 100 and serves as the light output window. Its design ensures that the light can pass through evenly and contact the skin on the surface of the hydrocolloid dressing 600, thereby optimizing the phototherapy effect. In addition, the light - guiding part 500 helps prevent light leakage, protecting the surrounding skin and eyes.

[0047] The hydrocolloid dressing 600 is pasted on the surface of the light - guiding part 500 and is in close contact with the skin. The hydrocolloid dressing 600 not only plays a fixing role but also provides a comfortable touch. There is skin - care essence in the hydrocolloid. When phototherapy is carried out, the thermal effect of light promotes the penetration of the skin - care essence and enhances its absorption rate. These essence components can nourish the skin, repair damaged cells, improve the skin barrier function, and further relieve skin problems caused by pimples.

[0048] By combining the advantages of phototherapy and skin - care essence, this design can not only effectively treat pimples but also provide skin repair and nourishment. Phototherapy has anti - inflammatory and bactericidal effects, and skin - care essence has repair and nourishment effects. The dual effects improve the overall skin - care level. The hydrocolloid phototherapy pimple patch is small, light, and easy to carry around. Users can use it at any time in daily life without complex equipment or professional places, meeting the needs of daily care. The designs of the light - concentrating glue 410 and the light - guiding part 500 optimize the distribution and intensity of light, making phototherapy more efficient. The light acts concentratedly on the pimple area, enhancing the treatment effect while reducing light waste. The hydrocolloid dressing 600 is soft and has good adhesion, which can closely fit the skin and provide a comfortable use experience. With the assistance of phototherapy, the skin - care essence can better penetrate the skin and play a role in moisturizing and repairing.

[0049] In this embodiment, the light - concentrating glue 410 is located on the side of the phototherapy lamp bead 400, and the phototherapy lamp bead faces the light - concentrating glue 410. By setting the light - concentrating glue 410 on the side of the phototherapy lamp bead 400 and designing two light - irradiation modes, the external - type and the internal - type, this design ensures the effective distribution and concentration of light. The external - type design is suitable for treating larger areas, while the internal - type design is more suitable for concentrating on irradiating specific pimple areas, meeting different treatment needs. This flexible design can provide corresponding phototherapy effects according to different pimple conditions, maximizing the accuracy and effect of treatment.

[0050] In the phototherapy acne patch, the phototherapy lamp beads 400 are powered by the power supply 200 and emit light of specific wavelengths, namely red light, blue light, and near-infrared light. The light-concentrating glue 410 is located on the side of the lamp beads, and its main function is to adjust the light path. Through its relative position with the phototherapy lamp beads 400, the light-concentrating glue 410 can guide and concentrate the light, improving the concentration and intensity of the light irradiation, and ensuring that the light irradiates the skin in a predetermined manner.

[0051] Refer to the appendix Figure 3 As shown, for the external light irradiation mode: In this mode, the light of the phototherapy lamp beads 400 is evenly emitted outward. Through the action of the light-concentrating glue 410, the light is guided to a wider skin area, which is suitable for cases that require large-area treatment. This mode helps to reduce the inflammation of the skin around the acne and improve the overall treatment effect.

[0052] For the internal light irradiation mode: In this mode, the light of the phototherapy lamp beads 400 is guided by the light-concentrating glue 410 to irradiate towards the center. The light is concentrated on the acne area, making the phototherapy effect more concentrated and significant, which is suitable for the treatment of relatively local and severe acne. The internal light irradiation mode can more precisely target the acne and provide a stronger treatment effect.

[0053] The light guide member 500 is installed at the opening of the housing 100 and serves as the light output interface. Its material and design enable the light to effectively pass through and irradiate the skin. The hydrocolloid dressing 600 is pasted on the surface of the light guide member 500 and is in direct contact with the skin. The skin care essence in the hydrocolloid is activated during the phototherapy process and penetrates into the skin, providing additional nourishment and repair for the treatment area.

[0054] Through the two product modes of external and internal light irradiation, this phototherapy acne patch can flexibly adjust the light distribution according to the actual treatment needs and provide targeted treatment. This flexibility enables it to adapt to different types and severities of acne problems.

[0055] In this embodiment, a circular boss 510 is provided on the side of the light guide member 500 facing the phototherapy lamp beads 400, and the circular boss 510 covers the phototherapy lamp beads 400 and the light-concentrating glue 410. By providing the circular boss 510 on the side of the light guide member 500 facing the phototherapy lamp beads 400, the aim is to optimize the light propagation path and enhance the phototherapy effect. The design of the circular boss 510 can cover the phototherapy lamp beads 400 and the light-concentrating glue 410, thereby achieving more effective light concentration and control. This structural design can ensure that the light irradiates the treatment area in a more concentrated and controllable manner, reducing light scattering and energy loss, and improving the accuracy and efficiency of the treatment.

[0056] The circular boss 510 on the light guide member 500 is designed as a structure surrounding the phototherapy lamp beads 400 and the light-concentrating glue 410.

[0057] The presence of the annular boss 510 can serve the following functions:

[0058] Focus light: The annular boss 510 can reflect and guide the light emitted by the phototherapy lamp beads 400, causing the light to undergo multiple reflections and refractions within the annular region. This design enables the light to be more concentrated, forming an illumination area with high light intensity and enhancing the effectiveness of phototherapy.

[0059] Reduce light scattering: Through the shielding effect of the annular boss 510, the light can be confined within a predetermined path, avoiding excessive scattering and leakage. This not only protects the user's eyes and the surrounding skin from being irritated by excessive light but also ensures that the light intensity is mainly concentrated on the acne and the treatment area, improving the efficiency of phototherapy.

[0060] The light - condensing glue 410 is located on the side of the phototherapy lamp beads 400 and works together with the annular boss 510. The light - condensing glue 410 is responsible for the initial light concentration, while the annular boss 510 further enhances this concentration effect. Through the reflection and refraction of the annular boss 510, the light can form a stronger illumination area before entering the skin, thereby achieving a better treatment effect. The light - guiding member 500 is installed at the opening of the housing 100 and serves as the outlet of the light. After being concentrated and controlled by the annular boss 510, the light is evenly distributed onto the surface of the hydrocolloid dressing 600 through the light - guiding member 500 and further irradiates the skin. This design ensures that the light output is both intense and uniform, effectively covering the acne area.

[0061] Reference appendix Figure 4 As shown in the figure, in this embodiment, the outer side of the annular boss 510 inclines inwards to form a reflective inclined surface 520. By designing the inward - inclined reflective inclined surface 520 on the outer side of the annular boss 510, it aims to further optimize the light propagation path and enhance the phototherapy effect. The design of this reflective inclined surface 520 not only helps to concentrate the light to form a stronger light ring but also effectively controls the direction of the light, ensuring that the light exits only from one side of the hydrocolloid dressing 600. This design can prevent the light from leaking from the side of the acne patch, improve the efficiency of phototherapy, and at the same time protect the surrounding skin and eyes from unnecessary light irritation.

[0062] The outer side of the annular boss 510 inclines inwards to form a reflective inclined surface 520. When the light emitted by the phototherapy lamp beads 400 irradiates on the reflective inclined surface 520, the light is reflected and concentrated within the annular region. This design enables the light to be concentrated on a stronger light ring, enhancing the intensity and uniformity of the light, and improving the effect of phototherapy. Through the design of the inclination angle of the reflective inclined surface 520 and the reflection path, the propagation direction of the light is effectively controlled. The light is guided to the front surface of the light-transmitting member and evenly distributed onto the skin through the light-transmitting member and the hydrocolloid dressing 600. This guidance of the light avoids the leakage of light from the side of the acne patch, ensuring that the light energy is mainly concentrated in the area to be treated.

[0063] The design of the reflective inclined surface 520 can not only concentrate the light but also prevent the light from leaking from the side of the device. Through this light guidance, it is ensured that the light only exits from one side of the hydrocolloid dressing 600, effectively avoiding the problem of light leakage from the side. In this way, not only the light utilization efficiency is improved, but also the user's eyes and the surrounding skin are protected, enhancing the safety of the phototherapy acne patch. The light is concentrated on a light ring, making the light intensity more concentrated and effective. Such a design can enhance the phototherapy effect, making the treatment more rapid and effective.

[0064] Under the guidance of the reflective inclined surface 520, the light is evenly distributed on the surface of the hydrocolloid dressing 600 through the light guide member 500. The light guide member 500 not only ensures the even distribution of the light but also works together with the reflective inclined surface 520 to prevent the light from leaking, improving the light utilization efficiency.

[0065] Reference appendix Figure 3 As shown in the figure, in this embodiment, it further includes a reflective film 700, and the reflective film 700 is located on the surface of the PCB board 300 and is arranged around the phototherapy lamp beads 400. The reflective film 700 is added to the design of the phototherapy acne patch, located on the surface of the PCB board 300 and around the phototherapy lamp beads 400. The main purpose of the reflective film 700 is to further enhance the light utilization efficiency. By reflecting the light emitted by the phototherapy lamp beads 400 back towards the light-transmitting member and the hydrocolloid dressing 600, the intensity and uniformity of the light are increased. Combining the design of the annular boss 510 and the reflective inclined surface 520, the application of the reflective film 700 can effectively improve the overall light efficiency of the phototherapy acne patch, making the phototherapy effect more significant.

[0066] The reflective film 700 is installed on the surface of the PCB board 300 and is arranged around the phototherapy lamp beads 400. When the phototherapy lamp beads 400 emit light, some of the light may propagate downward or sideways and fail to directly irradiate the light-transmitting member and the hydrocolloid dressing 600. The presence of the reflective film 700 causes these scattered lights to be reflected back upward, thereby being redirected to the effective area of the phototherapy acne patch, improving the utilization efficiency of the light. By reflecting the light, the reflective film 700 increases the intensity of the light within the phototherapy area. This increase in light intensity ensures the maximization of the phototherapy effect, enabling the light to act more effectively on the acne and the surrounding skin area.

[0067] The reflective film 700, together with the annular boss 510 and the reflective inclined surface 520, acts to cause the light to be reflected and concentrated multiple times along the irradiation path. This multi-level light control design ensures the high concentration and uniform distribution of the light, thereby forming a strong and uniform light ring in the phototherapy area and enhancing the effectiveness of the phototherapy. The reflective film 700 not only reflects the light that propagates downward and sideways but also, together with the reflective inclined surface 520, prevents the light from leaking out of the device interior. All the reflected and refracted lights are effectively controlled within the predetermined path, ensuring that the light is concentrated and irradiated on the target treatment area.

[0068] The light reflected by the reflective film 700 is evenly scattered onto the surface of the hydrocolloid dressing 600 through the light-transmitting member. The light-transmitting member ensures that the light can pass through effectively, while the hydrocolloid dressing 600 is in direct contact with the skin, maximizing the phototherapy effect.

[0069] In this embodiment, the light guide member 500 is detachably connected to the housing 100, and the PCB board 300 and the power supply 200 are detachably installed in the cavity. The detachable design is adopted, enabling the light guide member 500 to be detachably connected to the housing 100, and the PCB board 300 and the power supply 200 can be easily installed in the cavity of the housing 100. This design aims to improve the maintenance convenience of the device and the user experience, especially facilitating the cleaning and replacement of the power supply 200. Through the modular and detachable structure, users can more easily clean the device to ensure its hygiene condition; at the same time, the replacement of the power supply 200 becomes simpler and faster, meeting the continuous usage needs of users.

[0070] Through the detachable light guide member 500 design, users can regularly disassemble and clean the key components of the device to ensure the hygiene and safety of the device. Especially in the use of the hydrocolloid dressing 600 and the skin care essence, keeping the light guide member 500 clean helps prevent bacterial growth and protects the skin health of users.

[0071] The detachable design of the power supply 200 makes it simple and quick to replace the battery. Users can quickly replace the new power supply 200 when the device runs out of power, ensuring continuous use of the device. This design is very suitable for situations that require high-frequency use, such as daily acne care and skin treatment.

[0072] The detachable modular design makes the maintenance of the device simple and easy. Users can disassemble and replace the components of the device by themselves without professional technology or tools. This convenience improves the user experience and makes the device more acceptable and easier to use for consumers.

[0073] Reference appendix Figures 2-5 As shown, in this embodiment, a positive elastic contact 800 is provided at the bottom end of the cavity of the housing 100, and the positive elastic contact 800 is provided with a positive pin 810 detachably connected to the PCB board 300;

[0074] The power supply 200 is located between the positive elastic contact 800 and the PCB board 300, and a negative contact 310 is provided on the side of the PCB board 300 facing the power supply 200;

[0075] The positive elastic contact 800 and the negative contact 310 are respectively in contact with the positive and negative poles of the power supply 200 to form a power supply circuit. The design of using a button battery for power supply aims to reduce the volume and weight of the acne light therapy patch, and at the same time simplify its structure. This design choice suits the needs of portable devices, making the product more compact and easy to carry. By setting the positive and negative contacts 310 at the bottom end of the cavity of the housing 100 and using a button battery to form a power supply circuit, the volume and complexity of the product can be effectively reduced while maintaining the functions of the device.

[0076] A positive elastic contact 800 is provided at the bottom end of the cavity of the housing 100. This contact is designed to be detachably connected to the positive pin 810 on the PCB board 300. The positive elastic contact 800 ensures reliable electrical contact between the positive pole of the power supply 200 and the positive pole of the PCB board 300. A negative contact 310 is provided on one side of the PCB board 300. This contact is in contact with the negative pole of the power supply 200 to form the negative connection of the circuit. The negative contact 310 is designed to ensure stable electrical contact between the negative pole of the power supply 200 and the negative pole of the PCB board 300.

[0077] Button batteries are small in size and light in weight, suitable for the power requirements of portable devices such as acne light therapy patches. Using button batteries not only reduces the weight of the overall device, but also makes the device more compact, convenient for users to carry and use. The button battery is installed between the positive elastic contact 800 and the negative contact 310. When the device is assembled, the positive and negative poles of the button battery are respectively in contact with the positive and negative contacts 310 to form a complete power supply circuit, powering the light therapy lamp beads 400 on the PCB board 300 and starting the light therapy function.

[0078] By adopting the design of button battery and elastic contact piece, the use of complex battery connection wires and plugs is avoided, and the internal structure is simplified. This not only improves the reliability of the device, but also reduces the manufacturing cost and difficulty.

[0079] In this embodiment, an insulating sheet 900 is further included. A through groove 110 for the insulating sheet 900 to pass through is provided on the side surface of the housing 100, and the position of the through groove 110 corresponds to the position of the negative electrode contact 310;

[0080] When the insulating sheet 900 is inserted through the through groove 110, the insulating sheet 900 is located between the power supply 200 and the negative electrode contact 310 to isolate the electrical connection between the power supply 200 and the negative electrode contact 310. By adding the design of the insulating sheet 900 and the through groove 110, the insulating sheet 900 is used to replace the traditional switch to control the on-off state of the power supply 200. This design method helps to reduce the volume and weight of the product, simplify the device structure, enhance the portability of the device and the user experience. By providing the through groove 110 on the side surface of the housing 100, the insulating sheet 900 can be conveniently inserted or removed, so as to control the electrical connection state of the device and achieve the effect of a switch.

[0081] A through groove 110 is provided on the side surface of the housing 100, and the design of the through groove 110 corresponds to the position of the negative electrode contact 310. The through groove 110 allows the insulating sheet 900 to be inserted and removed, enabling the user to control the opening and closing of the circuit through simple operations. The insulating sheet 900 is an electrically insulating material, and its main function is to block the electrical connection between the power supply 200 and the negative electrode contact 310. When the insulating sheet 900 is inserted into the through groove 110, it is located between the power supply 200 and the negative electrode contact 310, isolating the circuit and preventing the current from passing through; when the insulating sheet 900 is removed, the negative electrode of the power supply 200 contacts the negative electrode contact piece to form a closed loop, the current flows, and the device starts to work.

[0082] When the insulating sheet 900 is inserted into the through groove 110 and located between the power supply 200 and the negative electrode contact 310, the negative electrode of the power supply 200 cannot contact the negative electrode contact 310, the circuit is isolated, and the device is in the off state. In this state, even if the button battery is installed in the device, no power will be consumed.

[0083] After the insulating sheet 900 is removed from the through groove 110, the negative electrode of the power supply 200 directly contacts the negative electrode contact 310, forming a complete circuit. The current starts to flow, supplying power to the phototherapy lamp beads 400 on the PCB board 300, and the device is in the working state. The user can control the opening and closing of the device by simply removing or inserting the insulating sheet 900.

[0084] By using a thin and lightweight insulating sheet 900 instead of a traditional mechanical switch, the volume and weight of the device are significantly reduced. The light therapy acne patch becomes thinner and lighter, making it easier to adhere to the skin, reducing the foreign body sensation when used by the user, and enhancing comfort. Using the insulating sheet 900 instead of a traditional mechanical switch can reduce the situation of the device falling due to gravity or external force. The insulating sheet 900 is located inside the device, has good fixity, is not easily interfered by the external environment, and ensures the stability of the device during use.

[0085] In this embodiment, the light therapy lamp beads 400 are 620 - 750nm red light lamp beads and / or 400 - 495nm blue light lamp beads and / or 700 - 1200nm near-infrared light lamp beads. By adjusting the trigger times of the switch, these lamp beads can respectively output red light, blue light, and near-infrared light to achieve different light therapy functions. Such a design aims to utilize the characteristics of light with different wavelengths to provide customized light therapy effects for different skin problems and treatment needs, improving the effectiveness of treatment and the user experience.

[0086] Red light lamp beads (620 - 750nm): Red light can penetrate the skin surface layer, promote blood circulation and cell regeneration, reduce inflammation and accelerate healing. Red light helps stimulate the production of collagen, and is suitable for reducing redness after acne and accelerating acne healing.

[0087] Blue light lamp beads (400 - 495nm): Blue light can effectively kill Propionibacterium acnes that causes acne, and helps control and reduce acne breakouts. The antibacterial property of blue light makes it an important means for treating acne, and is suitable for inhibiting inflammation and skin problems caused by bacteria.

[0088] Near-infrared light lamp beads (700 - 1200nm): Near-infrared light can penetrate deeper into the skin, and helps reduce deep inflammation and promote tissue repair. The penetrability of near-infrared light makes it suitable for relieving pain, reducing inflammation and promoting cell repair, especially for cystic acne and deep skin problems.

[0089] Through the control switch set on the device, the user can trigger the switch different times to select the output of light with different wavelengths. One trigger can select red light, two triggers can select blue light, and three triggers will switch to near-infrared light. In this way, the user can flexibly select the appropriate light therapy mode according to their skin condition and treatment needs.

[0090] This adjustable light therapy method enables the device to provide multi-functional treatment, and the user can select the corresponding light therapy mode according to different stages of skin problems. For example, when acne breaks out initially, select blue light to reduce inflammation and kill bacteria; when the acne gradually heals, select red light to promote repair; for deep skin problems, select near-infrared light.
