Description

Technical Field

[0001] This utility model relates to the technical field of phototherapy foot bath tubs, and in particular to a phototherapy foot bath tub. Background Technology

[0002] Phototherapy foot baths are health care devices that combine traditional foot baths with phototherapy technology, and have gained increasing attention in the health and wellness field in recent years. They not only have the foot-soaking function of ordinary foot baths, but also irradiate the feet with specific wavelengths of light (such as red light and infrared light) to achieve multiple health benefits, including promoting blood circulation, relieving fatigue, and improving sleep.

[0003] Currently, existing phototherapy foot bath tubs suffer from the following technical problems: 1. Unreasonable light source arrangement and incomplete irradiation coverage: In existing products, the light source (such as LED red / infrared light) is often only placed at the bottom of the tub or in a single location, resulting in the light only acting on the sole of the foot and failing to effectively cover areas such as the sides of the foot, the back of the foot, the ankle, and even the calf, affecting the overall phototherapy effect. 2. Unreasonable tub structure design, affecting phototherapy layout: The structure of the tub lid, lining, and bottom does not fully consider the installation space and wiring layout of the light source module, sensor, and control module, resulting in difficulties in installing the light control components, messy wiring, lack of waterproofing, or aesthetic impact. 3. Inconvenient cleaning: Some existing foot bath tubs have an integrated water tank design that cannot be disassembled, making the foot bath tub difficult to clean and thus affecting the cleaning effect. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the technical problem to be solved by this utility model is to provide a phototherapy foot bath tub, which solves the problems of unreasonable light source arrangement and incomplete irradiation coverage; unreasonable tub structure design affecting phototherapy layout; and inconvenient cleaning in the prior art.

[0005] To achieve the above objectives, this utility model provides a phototherapy foot bath tub, comprising:

[0006] A barrel body and a light control component, wherein the light control component is disposed inside the barrel body;

[0007] The bucket body includes: a bucket body, an inner liner, a bucket lid, and a water storage box, wherein: the inner liner is fitted inside the bucket body; the bucket lid is detachably installed on top of the bucket body, and the bucket lid includes an upper lid and a lower lid, which are rotatably connected; the water storage box is detachably fitted inside the inner liner to hold phototherapy foot bath water.

[0008] The light control assembly includes a first light control group, a second light control group, and a third light control group. The first light control group is located at the top of the lid and emits light towards the area above the foot support position. The second light control group is located on the side wall of the lining and emits light towards the side area of ​​the foot support position. The third light control group is located at the bottom of the lining and emits light towards the sole area of ​​the foot. Each of the first, second, and third light control groups is equipped with a light source component of a specific wavelength.

[0009] As a preferred approach, the first light control group includes multiple first light source components, which are disposed inside the lower cover and arranged downwards to emit light towards the area above the foot bearing position. Traditional designs may place the light source at the center of the top of the lid or a fixed point, resulting in uneven light scattering or difficulty in covering the entire area above the foot. Arranging multiple first light source components inside the lower cover and downwards allows for uniform light coverage of the instep, ankle, and even part of the lower leg, ensuring sufficient and soft illumination of the area above the foot bearing position. This facilitates effective phototherapy targeting the upper part of the foot, improving the targeting and uniformity of the phototherapy. Furthermore, integrating the first light source components inside the lower cover, rather than exposing them on the top of the lid or other external locations, makes the overall structure more compact and aesthetically pleasing. This avoids the need for light source windows or complex light-transmitting structures on the top of the lid, simplifying the manufacturing and assembly of the lid. Simultaneously, this built-in approach also helps protect the light source from moisture, dust, or accidental impacts, extending its lifespan. Furthermore, multiple primary light source components (such as LED beads) can be evenly arranged in an array on the inner side of the lower cover, which facilitates the adjustment of light source density, power and wavelength distribution according to needs. If a light source fails, it is also convenient for subsequent modular replacement or maintenance.

[0010] As a more preferred approach, the second light control group includes multiple second light source components, which are disposed on the inner sidewall of the liner and arranged circumferentially to emit light onto the lateral area of ​​the foot bearing position. By uniformly arranging multiple second light source components circumferentially along the inner sidewall of the liner, all-round, circumferential illumination of the lateral area of ​​the foot can be achieved, ensuring that light covers both sides of the foot from multiple angles, including areas that are difficult to fully reach with traditional phototherapy, such as the outer ankle, the arch, and the edge of the sole, thereby effectively improving the comprehensiveness and uniformity of phototherapy. In addition, since the light source is distributed on the sidewall of the liner, maintaining a close and reasonable distance from the side of the foot, it not only improves the utilization efficiency of light but also ensures that the light acts on the target area with appropriate intensity, which helps to enhance the phototherapy effect. Furthermore, this design integrates the light source into the sidewall of the liner, which is not only compact and rationally laid out but also helps to protect the light source from external moisture, dust, and accidental impacts, improving the lifespan and operational stability of the light source.

[0011] As a preferred approach, the third light control group includes multiple third light source components. These components are positioned at the bottom of the lining and arranged at equal intervals to emit light towards the area supporting the foot. Evenly distributing and arranging multiple third light source components at equal intervals on the bottom of the lining ensures that light is evenly distributed and irradiated across all areas of the foot, including important areas such as the heel, arch, forefoot, and toe base. This achieves high uniformity and full coverage of foot phototherapy, avoiding areas that are too bright or too dark, and improving the overall phototherapy effect. Furthermore, the modular arrangement of the multiple third light source components facilitates adjustments to the light source according to different user needs, further enhancing the product's functional expandability and personalized user experience.

[0012] As a preferred approach, the first, second, and third light source components all include LED light-emitting units and driving circuits. Using LED light-emitting units as the light source offers advantages such as low energy consumption, low heat generation, long lifespan, and fast response, making it ideal for use in foot bath equipment that operates for extended periods. This not only effectively reduces operating costs and energy consumption but also minimizes safety hazards caused by high temperatures, improving the overall safety and durability of the product. Furthermore, by configuring independent driving circuits for each light source component (including the light sources in the first, second, and third light control groups), precise control of each LED unit can be achieved, such as brightness adjustment, on / off control, wavelength output management (if multi-color or tunable spectrum LEDs are used), and real-time monitoring of operating status. This provides more flexible and reasonable light parameter configurations for the phototherapy process, meeting the personalized needs of different users and treatment scenarios. Furthermore, by integrating the LED light-emitting unit and driving circuit into each light source component, the overall light control system has a high degree of modularity and standardization. This not only facilitates production assembly, subsequent maintenance and troubleshooting, but also allows for flexible adjustment of the configuration of single or multiple light source modules according to functional expansion needs, thereby enhancing the product's flexibility and application value.

[0013] As a preferred approach, the first, second, and third light control groups are all equipped with waterproof sleeves to prevent moisture from penetrating the interior of the corresponding light source modules. By providing dedicated waterproof sleeves to the outside of the light source modules, a reliable physical barrier is created for the first light control group (typically located inside the lower lid), the second light control group (located on the inner lining sidewall), and the third light control group (located at the bottom of the inner lining). This effectively prevents water vapor, splashes, cleaning water, or humid air generated during foot baths from entering the light source, avoiding short circuits, component aging, LED failure, or damage to the drive circuit caused by moisture intrusion. This significantly improves the operational stability and lifespan of the light source modules. Furthermore, this waterproof design enhances the overall safety of the product, especially in home or public environments, preventing electric shocks or fires caused by moisture-induced leakage from electrical components, providing users with a safer and more reliable user experience. Furthermore, the waterproof sleeve helps protect the optical performance of the light source module, preventing moisture from condensing and adhering on the lens, light guide material, or lamp surface, thereby maintaining the uniformity and intensity of light and ensuring the continuous and stable effect of phototherapy.

[0014] As a preferred embodiment, the upper and lower lids of the bucket are hinged on the same side, allowing the upper lid to flip relative to the lower lid to open or close the top of the bucket. By providing hinges on the same side of the upper and lower lids, the upper lid can flexibly flip around the hinge point, easily opening and closing the top of the bucket. Users can easily open the bucket with one hand or by applying simple force, eliminating the need for complex lifting or disassembly processes, greatly improving ease of use and operational efficiency. Furthermore, this design connects the upper and lower lids into a single, integrated structure via hinges. Compared to directly connecting the upper lid to the bucket body or using a separate design, this not only enhances the overall integrity and stability of the lid structure but also simplifies the assembly of the opening and closing mechanism, improving the manufacturing process and reliability of the product. Furthermore, the flip-open design of the top lid relative to the bottom lid allows the top opening of the bucket to form a natural angle and space when opened. This not only makes it easy for users to put their feet in or out, but also avoids the problem of traditional top lids taking up too much space when fully opened, thus optimizing space utilization and operational comfort during use. The top lid can be flipped open separately, eliminating the need to lift the entire lid (if it's a one-piece design), making operation more effortless and convenient.

[0015] As a preferred embodiment, both the upper and lower covers are provided with arc-shaped openings, allowing the user to place their legs inside the tub. By providing these arc-shaped openings on the upper and lower covers, the user can easily insert their lower leg into the tub without excessive bending or stooping, significantly improving comfort during use. Furthermore, the placement of the arc-shaped openings near the junction of the foot and lower leg allows the foot and lower leg to naturally rest within the phototherapy area, ensuring complete light coverage of the foot and ankle, and even part of the lower leg. The user does not need to completely immerse or excessively bend their leg to allow the light control components (especially the side and top light sources) to effectively act on the target area. This helps improve the uniformity and targeting of the phototherapy effect, particularly for the reflex zones and meridian areas around the ankle. It also ensures precise alignment between the phototherapy area and the area to be treated, improving phototherapy efficiency and effectiveness. Furthermore, both the top and bottom covers are equipped with arc-shaped opening slots. Whether the top cover is open or closed, the opening slots are always present and usable, allowing users to smoothly insert their legs from above or the side (depending on the design). When the top cover is closed, the arc-shaped openings cooperate with the internal space of the tub to maintain good light path and spa environment without compromising the overall airtightness and functional layout. This achieves a high degree of unity between structure and function, enhancing the overall design coordination and practicality.

[0016] As a preferred approach, a touchscreen is positioned above the lower cover, with pre-set water temperature control buttons. The touchscreen's location above the lower cover, within the user's natural line of sight and operating range while seated, allows for easy parameter adjustment. The pre-set water temperature control buttons on the touchscreen enable users to adjust the water temperature with a single touch or simple touch control, eliminating the need for complex procedures. Compared to traditional mechanical knobs, hidden buttons, or external remote controls, the touchscreen is more intuitive, responsive, and clearer, enhancing the overall interactive experience. Furthermore, the placement of the touchscreen above the lower cover, close to the area where the user's hands naturally rest when seated, is a logical structural layout. Moreover, water temperature is a crucial parameter in foot baths; excessively high temperatures can cause burns, while excessively low temperatures can affect the therapeutic effect. The pre-set water temperature buttons on the touchscreen allow users to precisely set the appropriate water temperature, meeting the comfort needs of different individuals. Additionally, real-time monitoring of the current water temperature prevents accidental operation or the risk of overheating, enabling safe, comfortable, and personalized temperature management, improving the quality of the foot bath experience, and reducing safety risks such as burns.

[0017] As a more preferred approach, the light control component further includes a control module; the control module includes any one of an MCU controller, an FPGA controller, and an ASIC controller. The phototherapy effect is highly dependent on factors such as the wavelength, light intensity, irradiation time, and irradiation mode of the light source. By introducing a dedicated control module (MCU / FPGA / ASIC), the on / off state and brightness of each light source can be precisely controlled (e.g., PWM dimming), and LEDs of different wavelengths can be lit in a specific sequence or combination (e.g., red light → infrared light combination). This enables automatic switching and parameter adjustment of multiple phototherapy modes (e.g., soothing mode, vitality mode, repair mode), ensuring that the light source operates within a safe range and avoiding problems such as excessive brightness, overheating, or flickering, thereby achieving efficient and precise light source control. It is worth noting that this utility model provides a hardware structure and does not involve software technology updates. However, the technical solution of this utility model can be used in conjunction with existing software programs. For example, when combined with existing control programs, the control module can control the first light control group, the second light control group, and the third light control group, thereby changing parameters such as irradiation time and intensity.

[0018] As described above, the phototherapy foot bath tub of this utility model has the following beneficial effects: When in use, the phototherapy foot bath tub of this utility model uses three light control groups to irradiate from the top, sides, and bottom respectively, achieving all-round light coverage; the first light control group (top): faces the upper area of ​​the foot (such as the ankle and instep), irradiating the upper part of the foot and superficial tissues; the second light control group (side wall): faces the side area of ​​the foot, irradiating the side of the foot and the area around the ankle, compensating for the blind spots of the top and bottom light sources; the third light control group (bottom): faces directly towards the sole area of ​​the foot, ensuring that all areas of the foot (sole, instep, ankle, and side of the foot) are effectively affected by specific wavelengths of light through a multi-angle, three-dimensional light layout. The light coverage is seamless, improving the comprehensiveness and uniformity of phototherapy, and helping to enhance the overall treatment effect.

[0019] The device employs a layered structure of "body + liner + water tank" to isolate the phototherapy components from water, ensuring the safety of the light source and facilitating cleaning and water changes. The removable water tank allows users to adjust the water volume, add herbs, or perform routine cleaning as needed. The lid features a rotating upper and lower connection, facilitating easy opening and closing, allowing users to easily insert / remove their feet, and also optimizing light source layout and internal space utilization, thus improving user convenience and maintenance ease. The hinged connection between the upper and lower lids allows for flexible opening of the upper lid without moving the entire lid, making operation easier and more convenient. It also facilitates timely observation and adjustment of the internal condition during phototherapy, enhancing user comfort and operational convenience.

[0020] The first, second, and third light source components all include LED light-emitting units and driving circuits. Using LED light-emitting units as the light source offers advantages such as low energy consumption, low heat generation, long lifespan, and fast response, effectively reducing operating costs and energy consumption. It also reduces safety hazards caused by high temperatures, improving the overall safety and durability of the product. Furthermore, by configuring independent driving circuits for each light source component (including the light sources in the first, second, and third light control groups), precise control of each LED unit can be achieved. This provides more flexible and reasonable light parameter configurations for the phototherapy process, meeting the personalized needs of different users and treatment scenarios.

It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit the utility model.

[0044] like Figures 1 to 3 As shown, this utility model provides a phototherapy foot bath tub, comprising:

[0045] A barrel body 1 and a light control component 2, wherein the light control component 2 is disposed inside the barrel body 1;

[0046] The barrel body 1 includes: a barrel body 14, an inner liner 13, a barrel lid 11, and a water storage box 12, wherein: the inner liner 13 is fitted inside the barrel body 14; the barrel lid 11 is detachably installed on top of the barrel body 14; the barrel lid 11 includes an upper cover 111 and a lower cover 112, which are rotatably connected; and the water storage box 12 is detachably fitted inside the inner liner 13 to hold phototherapy foot bath water.

[0047] The light control assembly 2 includes a first light control group 21, a second light control group 22, and a third light control group 23. The first light control group 21 is located at the top of the lid 11 and emits light towards the area above the foot support position. The second light control group 22 is located on the side wall of the liner 13 and emits light towards the side area of ​​the foot support position. The third light control group 23 is located at the bottom of the liner 13 and emits light towards the sole area of ​​the foot. Each of the first light control group 21, the second light control group 22, and the third light control group 23 is equipped with a light source component of a specific wavelength.

[0048] In some embodiments of this utility model, such as Figures 2 to 3As shown, the first light control group 21 includes multiple first light source components 211. These components are disposed inside the lower cover 112 and face downwards to emit light towards the area above the foot bearing position. Traditional designs may place the light source at the center of the top of the cover 11 or at a fixed point, resulting in uneven light scattering or difficulty in covering the entire area above the foot. Arranging multiple first light source components 211 inside the lower cover 112 and facing downwards allows for uniform light coverage of the instep, ankle, and even part of the lower leg, ensuring sufficient and soft illumination of the area above the foot bearing position. This facilitates effective phototherapy targeting the upper part of the foot, improving the targeting and uniformity of the phototherapy. Furthermore, integrating the first light source components 211 inside the lower cover 112, rather than exposing them on the top of the cover 11 or other external locations, makes the overall structure more compact and aesthetically pleasing. It avoids the need for light source windows or complex light-transmitting structures on the top of the cover 11, simplifying the processing and assembly of the cover 11. Simultaneously, this built-in design also helps protect the light source from moisture, dust, or accidental impacts, extending its service life. Furthermore, multiple first light source components 211 (such as LED beads) can be evenly arranged in an array on the inner side of the lower cover 112, which facilitates the adjustment of light source density, power and wavelength distribution according to needs. If a light source fails, it is also convenient for subsequent modular replacement or maintenance.

[0049] In some embodiments of this utility model, such as Figure 3 As shown, the second light control group 22 includes multiple second light source components 221. These components are disposed on the inner sidewall of the liner 13 and arranged circumferentially to emit light onto the lateral area of ​​the foot bearing position. By uniformly arranging the multiple second light source components 221 circumferentially along the inner sidewall of the liner 13, all-round, circumferential illumination of the lateral area of ​​the foot can be achieved, ensuring that light covers both sides of the foot from multiple angles, including areas that are difficult to fully reach with traditional phototherapy, such as the outer ankle, the arch, and the edge of the sole, thereby effectively improving the comprehensiveness and uniformity of phototherapy. Furthermore, since the light source is distributed on the sidewall of the liner 13, maintaining a close and reasonable distance from the lateral side of the foot, it not only improves the utilization efficiency of light but also ensures that the light acts on the target area with appropriate intensity, which helps to enhance the phototherapy effect. Moreover, this design, by embedding the light source within the sidewall of the liner 13, not only has a compact structure and reasonable layout but also helps protect the light source from external moisture, dust, and accidental impacts, improving the lifespan and operational stability of the light source.

[0050] In some embodiments of this utility model, such as Figure 3As shown, the third light control group 23 includes multiple third light source components 231. These components are disposed at the bottom of the inner lining 13 and arranged at equal intervals to emit light towards the area supporting the foot. The evenly distributed arrangement of multiple third light source components 231 at the bottom of the inner lining 13 ensures that light shines from below the foot with uniform intensity and distribution across all areas of the foot, including important areas such as the heel, arch, forefoot, and toe roots. This achieves high uniformity and full coverage of foot phototherapy, avoiding localized over-brightness or under-brightness and improving the overall phototherapy effect. Furthermore, the modular arrangement of the multiple third light source components 231 facilitates subsequent adjustments to the light source according to different user needs, further enhancing the product's functional expandability and personalized user experience.

[0051] In some embodiments of this utility model, such as Figure 3 As shown, the first light source component 211, the second light source component 221, and the third light source component 231 all include LED light-emitting units and driving circuits. Using LED light-emitting units as the light source has advantages such as low energy consumption, low heat generation, long lifespan, and fast response, making it very suitable for use in foot bath equipment that operates for extended periods. This not only effectively reduces operating costs and energy consumption but also reduces safety hazards caused by high temperatures, improving the overall safety and durability of the product. Furthermore, by configuring an independent driving circuit for each light source component (including the light sources in the first, second, and third light control groups 23), precise control of each LED unit can be achieved, such as brightness adjustment, on / off control, wavelength output management (if multi-color or tunable spectrum LEDs are used), and real-time monitoring of the working status. This provides more flexible and reasonable light parameter configurations for the phototherapy process, meeting the personalized needs of different users and treatment scenarios. It should be emphasized and explained here that the phototherapy foot bath provided by this utility model focuses on its hardware structure and does not involve any software technology updates. The phototherapy foot bath tub of this utility model can be used alone or in conjunction with existing software programs to perform the above-mentioned functions such as brightness adjustment, on / off control, wavelength output management (if using multi-color or tunable spectrum LEDs), and real-time monitoring of working status, thereby providing more flexible and reasonable light parameter configuration for the phototherapy process. However, any content that may involve software is not within the protection scope of this utility model.

[0052] Furthermore, by integrating the LED light-emitting unit and driving circuit into each light source component, the overall light control system has a high degree of modularity and standardization. This not only facilitates production assembly, subsequent maintenance and troubleshooting, but also allows for flexible adjustment of the configuration of single or multiple light source modules according to functional expansion needs, thereby enhancing the product's flexibility and application value.

[0053] In some embodiments of this utility model, such as Figure 2 As shown, the first light control group 21, the second light control group 22, and the third light control group 23 are all equipped with waterproof sleeves. These waterproof sleeves prevent moisture from penetrating the interior of the corresponding light source modules. By setting dedicated waterproof sleeves on the outside of the light source modules, a reliable physical barrier is provided for the first light control group 21 (usually located inside the lower cover 112 of the bucket lid 11), the second light control group 22 (located on the side wall of the inner lining 13), and the third light control group 23 (located at the bottom of the inner lining 13). This effectively prevents water vapor, splashing water, cleaning water, or humid air generated during the foot bath from entering the interior of the light source, avoiding short circuits, component aging, LED failure, or damage to the drive circuit caused by moisture intrusion. This significantly improves the working stability and service life of the light source modules. In addition, this waterproof design enhances the overall safety of the product, especially in home or public places, preventing electric shock or fire accidents caused by electrical leakage due to moisture in electrical components, providing users with a safer and more reliable user experience. Furthermore, the waterproof sleeve helps protect the optical performance of the light source module, preventing moisture from condensing and adhering on the lens, light guide material, or lamp surface, thereby maintaining the uniformity and intensity of light and ensuring the continuous and stable effect of phototherapy.

[0054] In some embodiments of this utility model, such as Figures 1 to 2 As shown, hinges are provided on the same side of the upper cover 111 and the lower cover 112 of the bucket lid 11, allowing the upper cover 111 to flip relative to the lower cover 112 to open or close the top of the bucket body 1. By providing hinges on the same side of the upper cover 111 and the lower cover 112, the upper cover 111 can flexibly flip around the hinge point, thus easily realizing the opening and closing operation of the top of the bucket body 1. Users can complete the opening action with just one hand or simple force, without complicated lifting or disassembly procedures, greatly improving the convenience and efficiency of use. In addition, this design connects the upper cover 111 and the lower cover 112 into an integral linkage structure through hinges. Compared with directly connecting the upper cover 111 to the bucket body 14 or adopting a separate design, this not only enhances the integrity and stability of the bucket lid 11 structure, but also simplifies the assembly difficulty of the opening and closing mechanism, which is conducive to improving the manufacturing process and reliability of the product. Furthermore, the flip-opening mechanism of the upper cover 111 relative to the lower cover 112 allows the top opening of the bucket 1 to form a natural angle and space when opened. This not only makes it easy for users to put their feet in or out, but also avoids, to some extent, the problem of traditional top covers taking up too much space when fully opened, thus optimizing space utilization and operational comfort during use. The upper cover 111 can be flipped open independently, without having to lift the entire bucket cover 11 (if it is a one-piece design), making operation more effortless and convenient.

[0055] In some embodiments of this utility model, such as Figures 2 to 3As shown, both the upper cover 111 and the lower cover 112 are provided with arc-shaped openings, which allow the user to place their legs inside the barrel 1. By providing arc-shaped openings on the upper cover 111 and the lower cover 112, the user can easily insert their lower leg into the barrel through the opening without excessive bending or stooping, significantly improving comfort during use. Furthermore, the arc-shaped openings are positioned near the junction of the foot and lower leg, allowing the foot and lower leg to naturally rest in the phototherapy area, ensuring complete light irradiation coverage of the foot and ankle, and even part of the lower leg. The user does not need to completely immerse or excessively bend their leg to allow the light control components 2 (especially the side wall and top light sources) to effectively act on the target area. This helps improve the uniformity and targeting of the phototherapy effect, particularly the irradiation of the reflex zones and meridian areas around the ankle. It also ensures precise correspondence between the phototherapy area and the area to be treated, improving phototherapy efficiency and effectiveness. Furthermore, both the upper cover 111 and the lower cover 112 are provided with arc-shaped opening slots. Regardless of whether the upper cover 111 is open or closed, the opening slots are always present and usable, allowing users to smoothly insert their legs from above or the side (depending on the design). When the upper cover 111 is closed, the arc-shaped openings cooperate with the internal space of the tub 1 to maintain a good light path and spa environment without compromising the overall airtightness and functional layout. This achieves a high degree of unity between structure and function, enhancing the overall design coordination and practicality.

[0056] In some embodiments of this utility model, such as Figure 2 As shown, a touchscreen is located above the lower cover 112, and the touchscreen has a preset water temperature control button. The touchscreen is positioned above the lower cover 112, within the user's natural line of sight and operating range while seated, allowing for easy parameter adjustment. The preset water temperature control button on the touchscreen allows users to adjust the water temperature with a single touch or simple touch control, eliminating the need for complex procedures. Compared to traditional mechanical knobs, hidden buttons, or external remote controls, the touchscreen is more intuitive, responsive, and clearer, enhancing the overall interactive experience. Furthermore, the placement of the touchscreen above the lower cover 112, close to the area where the user's hands naturally rest when seated, is a logical structural layout. Moreover, water temperature is a crucial parameter in foot baths; excessively high temperatures can cause burns, while excessively low temperatures can affect the therapeutic effect. The preset water temperature button on the touchscreen allows users to precisely set a suitable water temperature, meeting the comfort needs of different individuals. Secondly, real-time monitoring of the current water temperature prevents accidental operation or the risk of overheating, achieving safe, comfortable, and personalized temperature management, improving the quality of the foot bath experience, and reducing safety risks such as burns.

[0057] In some embodiments of this utility model, such as Figure 2As shown, the light control component 2 also includes a control module; the control module includes any one of an MCU controller, an FPGA controller, and an ASIC controller. The phototherapy effect is highly dependent on factors such as the wavelength, light intensity, irradiation time, and irradiation mode of the light source. By introducing a dedicated control module (MCU / FPGA / ASIC), the on / off state and brightness of each light source can be precisely controlled (e.g., PWM dimming), and LEDs of different wavelengths can be lit in a specific order or combination (e.g., red light → infrared light combination). This enables automatic switching and parameter adjustment of multiple phototherapy modes (e.g., soothing mode, vitality mode, repair mode), ensuring that the light source operates within a safe range and avoiding problems such as excessive brightness, overheating, or flickering, thereby achieving efficient and precise light source control. It is worth noting that this utility model provides a hardware structure and does not involve software technology updates. However, the technical solution of this utility model can be used in conjunction with existing software programs. For example, after being combined with existing control programs, the control module can control the first light control group 21, the second light control group 22, and the third light control group 23, thereby changing parameters such as irradiation time and intensity.

[0058] As described above, the phototherapy foot bath tub of this utility model has the following beneficial effects: When in use, the phototherapy foot bath tub of this utility model uses three light control groups to irradiate from the top, sides, and bottom respectively, achieving all-round light coverage; the first light control group 21 (top): faces the upper area of ​​the foot (such as the ankle and instep), irradiating the upper part of the foot and superficial tissues; the second light control group 22 (side wall): faces the side area of ​​the foot, irradiating the side of the foot and the area around the ankle, compensating for the blind spots of the top and bottom light sources; the third light control group 23 (bottom): faces directly towards the sole area of ​​the foot, ensuring that all areas of the foot (sole, instep, ankle, and side of the foot) are effectively affected by specific wavelengths of light through a multi-angle, three-dimensional light layout. The light coverage is seamless, improving the comprehensiveness and uniformity of phototherapy, and helping to enhance the overall treatment effect.

[0059] The device employs a layered structure of "body 14 + liner 13 + water tank 12" to isolate the phototherapy components from water, ensuring the safety of the light source and facilitating cleaning and water changes. The detachable water tank 12 allows users to adjust the water volume, add herbs, or perform routine cleaning as needed. The lid 11 features a rotating connection between the upper and lower lids 112, facilitating easy opening and closing. Users can easily place / remove their feet, which also optimizes light source layout and internal space utilization, enhancing user convenience and maintenance ease. The upper and lower lids 111 are hinged, allowing users to easily open the upper lid without moving the entire lid 11, making operation easier and more convenient. This also facilitates timely observation and adjustment of the internal condition during phototherapy, improving user comfort and operational convenience.

[0060] The first light source component 211, the second light source component 221, and the third light source component 231 all include LED light-emitting units and driving circuits. Using LED light-emitting units as the light source offers advantages such as low energy consumption, low heat generation, long lifespan, and fast response, effectively reducing operating costs and energy consumption. It also reduces safety hazards caused by high temperatures, improving the overall safety and durability of the product. Furthermore, by configuring an independent driving circuit for each light source component (including the light sources in the first light control group 21, the second light control group 22, and the third light control group 23), precise control of each LED unit can be achieved. This provides more flexible and reasonable light parameter configurations for the phototherapy process, meeting the personalized needs of different users and in different treatment scenarios.

[0061] In summary, the phototherapy foot bath tub of this utility model has the following advantages:

[0062] 1. Comprehensive, all-around light therapy coverage:

[0063] Through a multi-angle, three-dimensional layout of three light control groups—top, side, and bottom (foot area)—combined with precise irradiation of multi-wavelength light, it ensures that all areas of the foot (sole, instep, ankle, and sides) can be effectively treated, significantly improving the comprehensiveness and uniformity of phototherapy and enhancing the overall treatment effect.

[0064] 2. Easy to install and maintain:

[0065] The device adopts a layered structure of "tube body 14 + lining 13 + water tank 12" to isolate the phototherapy components from the water, which not only ensures the safety of the light source but also facilitates cleaning and water replacement. The water tank 12 can be flexibly disassembled, supporting the adjustment of water volume, the addition of medicinal materials, or daily cleaning as needed, thus combining functionality and practicality.

[0066] 3. Easy to operate and highly comfortable:

[0067] The lid 11 is designed to open and close flexibly through the rotating connection between the upper lid 111 and the lower lid 112 (such as a hinge connection). Users can easily put in / take out their feet, while optimizing the layout of the light source and the utilization of the space inside the barrel. The upper lid 111 can be opened flexibly without the whole body moving, which makes it easy to observe or adjust the internal condition during phototherapy, improving the convenience of operation and the comfort of use.

[0068] It needs to be emphasized again that this utility model provides a phototherapy foot bath tub, which only protects the structural innovation of the foot bath tub and does not involve any software or program improvement.

[0069] In summary, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.
