[0002] Phototherapy refers to the treatment and maintenance of the human body using light of specific wavelengths and intensities, and it has wide applications in medicine, cosmetology, and many other fields. Phototherapy achieves its therapeutic function based on the bioregulatory effects of light; different wavelengths of light can be absorbed by different components in human tissues, thereby producing a series of physiological reactions. For example, ultraviolet (UV) phototherapy can induce photochemical reactions in the DNA of skin cells, thereby regulating cell proliferation and differentiation. Visible and near-infrared light can affect cell metabolism and activity by regulating mitochondrial function within cells. However, because phototherapy requires specialized equipment, users need to spend time specifically for phototherapy, resulting in a poor user experience. Utility Model Content

[0009] Technical solution five based on technical solution three: The optical lens is a condenser lens.

[0014] Technical solution ten, based on technical solution one, also includes a power supply component; a wire hole is provided through the side of the water outlet seat away from the water outlet cover, and the wire hole is connected to the mounting cavity; the power supply component is adapted to be connected to an external power supply, and its wires are connected to the light-emitting component through the wire hole.
[0015] As can be seen from the above description of this utility model, compared with the prior art, this utility model has the following beneficial effects:
[0016] Technical solution one provides a shower device with phototherapy function. The shower device includes a shower body and a light-emitting component. The shower body includes a water outlet base and a water outlet cover, which cooperate to form a water outlet cavity. After the water outlet base is connected to the water inlet, water flows into the water outlet cavity and is ejected through the water outlet holes on the water outlet cover to form a water flow. A first light-emitting hole is also provided in the middle of the water outlet cover. The water outlet base also has a mounting cavity located inside the water outlet cavity, with its lower end open to form a second light-emitting hole. The position of the second light-emitting hole corresponds to the position of the first light-emitting hole. The light-emitting component includes a light-emitting circuit board and an optical lens, both of which are mounted on... Inside the installation cavity, when the light-emitting circuit board emits light, the light can be emitted outward through the optical lens. The optical lens can form a seal between the light-emitting circuit board and the second light outlet hole, preventing water from entering the installation cavity. Through the cooperation of the light-emitting component and the shower body, users can also receive phototherapy through the light-emitting component while showering, improving the user experience. At the same time, since the first and second light outlet holes are located in the middle of the shower body, when the light-emitting component emits light, some of the light will pass through the water flow and be refracted and reflected, thereby effectively increasing the illumination area of the light-emitting component and further improving the phototherapy effect.
[0017] In technical solution two, the water outlet holes on the water outlet cover are arranged in multiple rings around the first light outlet hole. This design allows the water flow to form a more reasonable and uniform water flow distribution when it sprays out of the water outlet holes. At the same time, in conjunction with the light-emitting component located in the middle, the light therapy light can be emitted in coordination with the water flow, optimizing the refraction and reflection of the light after passing through the water flow, thereby maximizing the effective irradiation area of the light therapy light, improving the light therapy effect, and making the shower experience more comfortable and diverse.
[0018] In technical solution three, the effect of the optical lens is defined. By configuring the optical lens, it is ensured that an appropriate proportion of light can be incident on the water flow of the innermost water outlet at a suitable angle. This allows the light to be scattered more effectively to the surroundings based on the refraction and reflection of the water flow, thereby increasing the illumination range of the light and expanding the effective phototherapy range, thus enhancing the overall effect of phototherapy.
[0019] In technical solution four, the circular first and second light-emitting holes are matched with the ring-shaped water outlets, allowing the light to be emitted more evenly to the outside. The water flow can also be sprayed out in a regular ring around the first and second light-emitting holes. When the light is emitted, the water flow can refract and reflect the light in a regular and uniform manner, ensuring that the light is affected more evenly in all directions. This makes the distribution of the phototherapy light in the entire shower area more uniform and stable, improving the consistency of the phototherapy effect.
[0020] In technical solution five, the optical lens is a focusing lens, which can efficiently guide and control light, reducing energy loss during light propagation. This allows the light emitted by the light-emitting component to be more concentrated and directional towards the target area, namely the water flow area through the water outlet and the shower space. In this way, at the same luminous power, more light can effectively participate in the phototherapy process. The water flow expands the irradiation range, enhancing the intensity and effect of phototherapy. It also helps improve the optical utilization efficiency of the entire phototherapy system, ensuring high-quality realization of the phototherapy function.
[0021] In technical solution six, the light-emitting component emits light in the 600-1070nm wavelength range. Light in this wavelength range typically has a good biostimulatory effect in the field of phototherapy, and can interact positively with human tissues, such as promoting cell metabolism and improving blood circulation. Selecting a light-emitting chip with this specific wavelength makes the phototherapy function of this shower device more targeted and effective, genuinely bringing beneficial health effects to users.
[0022] In technical solution seven, the output energy of the light-emitting circuit board is limited, which can ensure that there is enough light energy to act on the human body to achieve an effective phototherapy effect, while avoiding potential adverse effects on the human body caused by excessive light dose, such as skin burns.
[0023] In technical solution eight, the installation cavity is formed by the enclosure of the cylinder wall, which can isolate it from the water in the outlet cavity and prevent water from entering the installation cavity.
[0024] In technical solution nine, the lower end of the cylinder wall abuts against the water outlet cover along the first direction, which increases the connection stability between the water outlet seat and the water outlet cover, and at the same time can better seal the installation cavity, preventing water from entering the installation cavity from the gap.
[0025] In technical solution ten, a power supply component is provided, and a wire hole is provided on the water outlet base. The power supply component solves the power supply and control problem of the light-emitting component, and the wire hole allows the wires of the power supply component to pass through and supply power to the light-emitting component.

[0038] Example
[0039] This utility model relates to a shower device with phototherapy function, see reference. Figure 1 The shower device mainly includes a shower body 10 and a light-emitting component 20. In addition, the shower device also includes a power supply component.
[0040] The shower body 10 includes a water outlet base 11 and a water outlet cover 12; the water outlet base 11 is adapted to receive water and is fixedly connected with the water outlet cover 12 to form a water outlet cavity 13; the water outlet cover 12 is provided with a plurality of water outlet holes 120 communicating with the water outlet cavity 13 along a first direction, and a first light outlet hole 121 is provided in the middle along the first direction; the water outlet base 11 is provided with a mounting cavity 14 located in the water outlet cavity 13, and the lower end of the mounting cavity 14 is open to form a second light outlet hole 140, which corresponds to the light outlet hole.
[0041] The water outlet cover 12 has multiple rings of water outlet holes 120 surrounding the first light outlet hole 121, with the outermost rings of the water outlet holes 120 having larger diameters. The mounting cavity 14 is formed by a cylindrical wall 15, which extends from the inner wall of the water outlet seat 11 along a first direction toward the water outlet cover 12. The lower end of the cylindrical wall 15 abuts against the water outlet cover 12 along the first direction.
[0042] Specifically, refer to Figure 1 The shower body 10 has a separate design for the water outlet seat 11 and the water outlet cover 12. The water outlet seat 11 is bowl-shaped and has an opening that opens in a first direction. The water outlet cover 12 can be fitted to the opening of the water outlet seat 11 and cooperates with the water outlet seat 11 to form a water outlet cavity 13 enclosed by the two. In this embodiment, the water outlet seat 11 in the shower body 10 is also connected to a water inlet pipe 16. One end of the water inlet pipe 16 connected to the water outlet seat 11 forms a water passage 160, and the other end of the water inlet pipe 16 opposite to the water passage 160 forms a water inlet 161. The water inlet pipe 16 can be connected to external water through the water inlet 161 and the water is delivered to the water outlet cavity 13 through the water passage 160. The specific direction of the first direction is referred to Figure 1 and Figure 3 As shown.
[0043] Reference Figure 1The water outlet cover 12 is a flat cover whose shape matches the opening of the water outlet seat 11. It is detachably connected to the water outlet seat 11 by means of snap-fit or threaded engagement. A sealing ring can be installed at the connection between the water outlet cover 12 and the water outlet seat 11 to ensure a sealed connection between them. The water outlet cover 12 has several water outlet holes 120 extending along a first direction. One end of each water outlet hole 120 connects to the water outlet cavity 13, and the other end connects to the outside of the water outlet cover 12. Under water pressure, water in the water outlet cavity 13 will spray out from the water outlet holes 120 to form a water flow. At the center of the water outlet cover 12, a first light-emitting hole 121 extending along the first direction is also provided. The first light-emitting hole 121 has a large diameter, and in this embodiment, the first light-emitting hole 121 is circular. Furthermore, referring to… Figure 2 The water outlet holes 120 are arranged in a ring around the first light-emitting hole 121. Multiple water outlet holes 120 belonging to the same ring cooperate to form a water outlet ring, and the multiple water outlet rings are arranged outward from the first light-emitting hole 121 as the center. Furthermore, in a preferred embodiment, the diameter of the water outlet holes 120 in each water outlet ring increases with the distance from the first light-emitting hole 121. That is, the diameter of the water outlet holes 120 in the water outlet ring further away from the first light-emitting hole 121 is larger. In this embodiment, each ring of water outlet holes 120 on the water outlet cover 12 is annular, meaning each water outlet ring is annular to match the shape of the first light-emitting hole 121. The water outlet holes 120 on the water outlet cover 12 are arranged in multiple rings around the first light-emitting hole 121, and the diameter of the water outlet holes 120 in the outermost rings is larger. This design allows for a more reasonable and uniform water flow distribution when water is sprayed from the water outlet holes 120. The smaller diameter of the inner water outlet 120 allows for a relatively fine water flow near the light-emitting area of the phototherapy, ensuring that the refraction and reflection of the light are relatively gentle and uniform when the phototherapy light is emitted. The gradually increasing diameter of the outer ring allows for a wider water flow coverage. While ensuring overall shower comfort, the different states of the water flow in different layers further optimize the refraction and reflection of the light after passing through the water, thereby maximizing the effective irradiation area of the phototherapy light, enhancing the phototherapy effect, and making the shower experience more comfortable and diverse.
[0044] Reference Figure 1 and Figure 3An installation cavity 14 is provided on the water outlet base 11. This cavity 14 is formed by a cylindrical wall 15 extending along a first direction. One end of the cylindrical wall 15 connects to the inner wall of the water outlet base 11, and the other end abuts against the inner surface of the water outlet cover 12 after it is assembled onto the water outlet base 11. This increases the connection stability between the water outlet base 11 and the water outlet cover 12, and also better seals the installation cavity 14, preventing water from entering the cavity through gaps. Simultaneously, the lower end of the installation cavity 14, near the water outlet cover 12 in the first direction, is open and forms a second light-emitting hole 140. The second light-emitting hole 140 and the first light-emitting hole 121 are both circular in shape and have the same inner diameter. After the water outlet cover 12 is assembled onto the water outlet base 11, the positions of the first light-emitting hole 121 and the second light-emitting hole 140 coincide. Furthermore, referring to… Figure 3 A wire hole 110 is also provided on the side of the water outlet seat 11 away from the water outlet cover 12, and the wire hole 110 is connected to the mounting cavity 14.
[0045] Reference Figure 1 The light-emitting component 20 includes a light-emitting circuit board 21 and an optical lens 22; both the light-emitting circuit board 21 and the optical lens 22 are fixed in the mounting cavity 14, and the optical lens 22 blocks the second light-emitting hole 140. The light-emitting circuit board 21 is located inside the mounting cavity 14 relative to the optical lens 22, and the light-emitting direction of the light-emitting circuit board 21 points to the optical lens 22.
[0046] The optical lens 22 is used to adjust the illumination range of the light-emitting component 20, and it is configured such that at least 30% of the light from the light-emitting component 20 forms an angle of not less than 48° with the axis of the innermost water outlet 120.
[0047] Specifically, the light-emitting circuit board 21 uses an LED circuit board, which can achieve phototherapy function by emitting light of a specific wavelength and output dose. In this embodiment, the light-emitting circuit board 21 uses a light-emitting chip with an emission wavelength of 600-1070nm and an output energy range of 100-10000mW. Light in this wavelength band usually has a good biostimulatory effect in the field of phototherapy and can produce positive interactions with human tissues, such as promoting cell metabolism and improving blood circulation. Selecting such a specific wavelength light-emitting chip makes the phototherapy function of this shower device more targeted and effective, and can truly bring beneficial health effects to users. In addition, limiting the output dose of the light-emitting circuit board 21 can ensure that there is enough light energy to act on the human body to achieve an effective phototherapy effect, while avoiding potential adverse effects on the human body caused by excessive light dose, such as skin burns. (Refer to...) Figure 3The light-emitting circuit board 21 is bonded and fixed to the inner wall of the mounting cavity 14, and the light-emitting chip on it is positioned facing the optical lens 22 so as to emit light towards the optical lens 22.
[0048] The optical lens 22 is a condenser lens, which is bonded and fixed to the inner wall of the mounting cavity 14 and positioned near the second light-emitting hole 140 of the mounting cavity 14. In this embodiment, the edge of the optical lens 22 is approximately flush with the lower edge of the cylinder wall 15, and the optical lens 22 blocks the second light-emitting hole 140 of the mounting cavity 14 to prevent external liquid from entering the mounting cavity 14 and damaging the light-emitting circuit board 21. Furthermore, by adjusting the shape and position of the optical lens 22, the angle between at least 30% of the light from the light-emitting component 20 and the axis of the innermost water outlet hole 120 can be not less than 48°. It is easy to understand that after the light emitted by the light-emitting circuit board 21 is refracted and reflected by the optical lens 22, its light energy is more concentrated and the illumination range is controllable. The optical illumination range of the light-emitting component 20 can be divided into two parts. One part is located on the inner side and is bounded by the size of the optical lens 22, enclosed by a cylindrical surface parallel to the axis of the innermost water outlet 120. The light in this part does not intersect with the axis of the innermost water outlet 120. The other part is located on the outer side, which is diffused light. The optics of this part intersect with the axis of the innermost water outlet 120. The function of the optical lens 22 is to ensure that the angle between the light rays, which account for at least 30% of the total light energy in the diffused optics located on the outer side, and the axis of the water outlet 120 is not less than 48°. The axis of the innermost water outlet 120 is a virtual straight line that passes through the center of the water outlet 120 and is along the direction of water flow. By configuring the optical lens 22, it is ensured that an appropriate proportion of light can be incident on the water flow of the innermost water outlet 120 at a suitable angle, thereby scattering the light more effectively to the surroundings based on the refraction and reflection of the water flow, increasing the irradiation range of the light, and thus expanding the effective phototherapy range and enhancing the overall effect of phototherapy.
[0049] Furthermore, the circular first light-emitting hole 121 and second light-emitting hole 140 are matched with the ring-shaped water outlet holes 120, allowing the light to be emitted more evenly to the outside. The water flow can also be sprayed out in a regular ring around the first light-emitting hole 121 and second light-emitting hole 140. When the light is emitted, the water flow can refract and reflect the light in a regular and uniform manner, ensuring that the light is affected more evenly in all directions. This makes the distribution of the phototherapy light in the entire shower area more uniform and stable, improving the consistency of the phototherapy effect.
[0050] Meanwhile, the optical lens 22 is a total internal reflection lens, which can efficiently guide and control the light, reducing energy loss during light propagation. This allows the light emitted by the light-emitting component 20 to be more concentrated and directional towards the target area, namely the water flow area through the water outlet 120 and the shower space. In this way, at the same luminous power, more light can effectively participate in the phototherapy process, expanding the irradiation range through the water flow, enhancing the intensity and effect of phototherapy, and also helping to improve the optical utilization efficiency of the entire phototherapy system, ensuring the high-quality realization of the phototherapy function.
[0051] It should be noted that the shower device in this embodiment can be an overhead shower or a handheld shower. When it is an overhead shower, the phototherapy effect of the light-emitting component 20 can be effectively improved by setting the optical lens 22. However, when the shower device is a handheld shower, the water flow is bent due to gravity, so the phototherapy effect of the light-emitting component 20 will be affected by the bent water flow and change.
[0052] In addition, the power supply component can be connected to an external power source, and the power supply component includes a wire that can enter the mounting cavity 14 through the wire hole 110 on the water outlet 11 and connect to the light-emitting component 20.
[0053] The shower device with phototherapy function according to this embodiment includes a shower body 10 and a light-emitting component 20. The shower body 10 includes a water outlet base 11 and a water outlet cover 12, which cooperate to form a water outlet cavity 13. After the water outlet base 11 is connected to the water inlet, the water flows into the water outlet cavity 13 and is sprayed out through the water outlet hole 120 on the water outlet cover 12 to form a water flow. A first light outlet hole 121 is also provided in the middle of the water outlet cover 12. A mounting cavity 14 is also provided on the water outlet base 11. The mounting cavity 14 is located in the water outlet cavity 13 and its lower end is open to form a second light outlet hole 140. The position of the second light outlet hole 140 corresponds to the position of the first light outlet hole 121. The light-emitting component 20 includes a light-emitting circuit board 21 and an optical lens 22. Both are housed in the mounting cavity 14. When the light-emitting circuit board 21 emits light, the light can be emitted outward through the optical lens 22. The optical lens 22 can form a seal between the light-emitting circuit board 21 and the second light-emitting hole 140 to prevent water from entering the mounting cavity 14. With the cooperation of the light-emitting component 20 and the shower body 10, the user can also receive phototherapy through the light-emitting component 20 while showering, which improves the user's experience. At the same time, since the first light-emitting hole 121 and the second light-emitting hole 140 are located in the middle of the shower body 10, when the light-emitting component 20 emits light, some of the light will pass through the water flow and be refracted and reflected, thereby effectively increasing the illumination area of the light-emitting component 20 and further improving the phototherapy effect.
[0054] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this utility model, but does not constitute a limitation on the scope of protection of this utility model. Modifications, equivalent substitutions, or other improvements to the embodiments of this utility model or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this utility model or the foregoing embodiments, should all be included within the scope of protection of this utility model.
