The following description is provided to enable any person skilled in the art to make and use this application. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0029] like Figure 1 and Figure 2 As shown in the figure, this application provides a far-infrared eye care device, which includes an eye care device shell 1, a first far-infrared electric heating film 2 and multiple acupoint massage components 3, which can effectively provide daily eye care and physiotherapy and significantly improve the user's vision.

[0030] The first far-infrared electrothermal film 2 is disposed within the housing 1 of the eye massager, corresponding to the eye area. When powered on, it generates heat and transmits the heat to the user's eyes in the form of far-infrared thermal radiation, providing far-infrared therapy to areas of the eye other than acupoints around the eyes, such as the eyeball and eye socket. The first far-infrared electrothermal film 2 has multiple perforated portions 2a, which are arranged to correspond to acupoints around the eyes, ensuring that the first far-infrared electrothermal film 2 avoids the acupoints around the eyes at the perforated portions 2a. Here, the acupoints around the eyes can be one or more acupoints such as Zanzhu, Qingming, Sibai, and Taiyang.

[0031] Multiple acupoint massagers 3 are correspondingly disposed in the aforementioned multiple hollow sections 2a, with one acupoint massager 3 disposed in each hollow section 2a. Each acupoint massager 3 includes a massage vibrator 31 and a second far-infrared electrothermal film 32, the second far-infrared electrothermal film 32 covering the end of the massage vibrator 31. When energized, the massage vibrator 31 can vibrate to massage the acupoints around the eyes, while the second far-infrared electrothermal film 32 can generate heat when energized and transfer the heat to the acupoints around the eyes in the form of far-infrared thermal radiation, simultaneously achieving vibration massage and far-infrared therapy for the acupoints around the eyes, enhancing the massage and therapy effect.

[0032] The far-infrared thermal radiation wavelength range of the first far-infrared electrothermal film 2 and the second far-infrared electrothermal film 32 are 5–15 μm, respectively, while their electrothermal radiation conversion efficiencies are 65%–80%. Electrothermal radiation conversion efficiency refers to the percentage of total output radiant flux converted from input electrical power after the first far-infrared electrothermal film 2 / second far-infrared electrothermal film 32 reaches thermal equilibrium under rated voltage. In other words, after reaching thermal equilibrium under rated voltage, the first far-infrared electrothermal film 2 and the second far-infrared electrothermal film 32 can convert 65%–80% of the input electrical power into far-infrared thermal radiation in the 5–15 μm wavelength range, respectively. Thus, the first far-infrared electrothermal film 2 and the second far-infrared electrothermal film 32 can convert a large proportion of electrical energy into far-infrared thermal radiation within the target wavelength range, providing far-infrared thermal radiation with better therapeutic effects while ensuring high energy density, thereby significantly improving the user's vision.

[0033] Compared with related technologies, the far-infrared eye care device provided in this application embodiment uses a first far-infrared electrothermal film 2 to provide far-infrared therapy to areas of the eye other than acupoints around the eyes, and uses an acupoint massage component 3 to simultaneously provide vibration massage therapy and far-infrared therapy to acupoints around the eyes. The first far-infrared electrothermal film 2 and the second far-infrared electrothermal film 32 are configured to provide far-infrared heat radiation with better therapeutic wavelength and higher energy density, thereby achieving the physical therapy function for the eyes. According to actual use verification by volunteers, the far-infrared eye care device provided in this application embodiment can improve the average visual acuity of the volunteers by 0.2 to 0.6 (logarithmic visual acuity chart) and the overall visual acuity improvement rate reaches 98.3%, which can significantly improve the user's vision.

[0034] In some embodiments, the first far-infrared electrothermal film 2 may be provided with a first far-infrared electrothermal area and a second far-infrared electrothermal area. The first far-infrared electrothermal area is positioned corresponding to the eyeball and can provide far-infrared therapy to the eyeball, while the second far-infrared electrothermal area is positioned corresponding to the periorbital area and can provide far-infrared therapy to the periorbital area. The second far-infrared electrothermal area is positioned around the first far-infrared electrothermal area, and may continuously surround the entire edge area of ​​the first far-infrared electrothermal area, or may intermittently surround only a portion of the edge area of ​​the first far-infrared electrothermal area. Here, the heating temperature of the first far-infrared electrothermal area is configured to be lower than the heating temperature of the second far-infrared electrothermal area.

[0035] With the above settings, the first far-infrared electric heating film 2 can achieve zoned temperature control when powered on. This allows the far-infrared thermal radiation temperature of the first far-infrared electric heating zone to be relatively low, which can better match the lower comfort temperature of the eyeball. This allows for better far-infrared therapy to the eyeball at a comfortable temperature, enhancing the vision improvement effect and avoiding damage to the eyeball and optic nerve. Meanwhile, the far-infrared thermal radiation temperature of the second far-infrared electric heating zone is relatively high, which can better match the higher suitable temperature of the area around the eye, such as the eye socket. This allows for better far-infrared heat therapy to the area around the eye at a higher temperature, achieving a better heat therapy effect.

[0036] The film structure of the first far-infrared electrothermal film 2 can be determined according to actual needs, and this application embodiment does not limit it. For example Figure 3 As shown, in some examples, the first far-infrared electrothermal film 2 may include a first base film 21, a first conductive electrode layer 22, a first far-infrared heating coating 23, and a first insulating layer 24 stacked sequentially. The material of the first base film 21 can be determined according to actual needs, and may be one of the following material types: polyimide film, PET film, fabric, etc., which is not limited in this application embodiment.

[0037] The first insulating layer 24 covers the first far-infrared heating coating 23 to provide insulation protection for the first far-infrared heating coating 23. The type of the first insulating layer 24 can be determined according to actual needs, and can be, for example, insulating coating, insulating tape, insulating heat-pressed film, etc., which is not limited in this embodiment.

[0038] The first far-infrared heating coating 23 may include a first coating sub-part 231 and a second coating sub-part 232 disposed in the same layer. The first coating sub-part 231 is disposed in the first far-infrared electrothermal region, and the second coating sub-part 232 is disposed in the second far-infrared electrothermal region, with the second coating sub-part 232 surrounding the first coating sub-part 231. The material of the first far-infrared heating coating 23 can be determined according to actual needs and may be printed using materials such as graphene-based conductive ink; however, this embodiment does not limit this.

[0039] The first conductive electrode layer 22 may include a first electrode and a second electrode, which are disposed in the same layer at intervals. The first electrode has a first extension 2211, which extends along the adjacent portion of the first coating sub-part 231 and the second coating sub-part 232, that is, it is disposed between the first coating sub-part 231 and the second coating sub-part 232, such that the first extension 2211 contacts the first coating sub-part 231 and the second coating sub-part 232 respectively, forming a strip-shaped electrode segment located between the two. The second electrode has a second extension segment 2221 and an end extension segment 2222 connected in sequence. The second extension segment 2221 extends along the edge of the second coating sub-part 232 away from the first coating sub-part 231, and contacts the second coating sub-part 232 to form a strip electrode segment along the outer edge of the second coating sub-part 232. The end extension segment 2222 extends to the center of the first coating sub-part 231, contacts the central region of the second coating sub-part 232, and is spaced apart from the first extension segment 2211 to form a strip electrode segment located in the center of the second coating sub-part 232.

[0040] Thus, the first extension segment 2211 and the end extension segment 2222 can serve as the positive and negative electrodes of the first coating sub-section 231, respectively, while the first extension segment 2211 and the second extension segment 2221 can serve as the positive and negative electrodes of the second coating sub-section 232, respectively. When the first and second electrodes are energized, the first coating sub-section 231 and the second coating sub-section 232 are energized and generate heat, which is then transferred to the eyeball and the periorbital area in the form of far-infrared thermal radiation, respectively. Here, the heating temperature of the first coating sub-section 231 is configured to be lower than the heating temperature of the second coating sub-section 232, thereby achieving the aforementioned zoned temperature control effect.

[0041] Specifically, the power density of the first conductive electrode layer 22 and the first far-infrared heating coating 23 can be configured such that the power density of the first coating sub-section 231 is less than that of the second coating sub-section 232, thereby ensuring that the heating temperature of the first coating sub-section 231 is less than that of the second coating sub-section 232.

[0042] In some examples, the distance between the first extension segment 2211 and the second extension segment 2221 may not be greater than the distance between the first extension segment 2211 and the end extension segment 2222, while the sheet resistance of the first coating sub-portion 231 may be greater than the sheet resistance of the second coating sub-portion 232. For example, the distance between the first extension segment 2211 and the second extension segment 2221 may be equal to the distance between the first extension segment 2211 and the end extension segment 2222, while the sheet resistance of the first coating sub-portion 231 may be greater than the sheet resistance of the second coating sub-portion 232.

[0043] Under this configuration, since the distance between the first extension segment 2211 and the second extension segment 2221 is less than or equal to the distance between the first extension segment 2211 and the end extension segment 2222, and the sheet resistance of the first coating sub-section 231 is greater than the sheet resistance of the second coating sub-section 232, the coating resistance between the positive and negative electrodes in the first coating sub-section 231 is greater than the coating resistance between the positive and negative electrodes in the first coating sub-section 231. This results in the power of the first coating sub-section 231 being less than the power of the second coating sub-section 232, and consequently, the power density of the first coating sub-section 231 being less than the power density of the second coating sub-section 232. This ensures that the heating temperature of the first coating sub-section 231 is less than the heating temperature of the second coating sub-section 232.

[0044] In other examples, the distance between the first extension 2211 and the second extension 2221 may be less than the distance between the first extension 2211 and the end extension 2222, and the sheet resistance of the first coating sub-portion 231 may not be less than the sheet resistance of the second coating sub-portion 232. For example, the distance between the first extension 2211 and the second extension 2221 may be less than the distance between the first extension 2211 and the end extension 2222, and the sheet resistance of the first coating sub-portion 231 may be equal to the sheet resistance of the second coating sub-portion 232.

[0045] Under this configuration, since the distance between the first extension segment 2211 and the second extension segment 2221 is less than the distance between the first extension segment 2211 and the end extension segment 2222, and the sheet resistance of the first coating sub-section 231 is greater than or equal to the sheet resistance of the second coating sub-section 232, the coating resistance between the positive and negative electrodes in the first coating sub-section 231 is greater than the coating resistance between the positive and negative electrodes in the first coating sub-section 231. This results in the power of the first coating sub-section 231 being less than the power of the second coating sub-section 232, and consequently, the power density of the first coating sub-section 231 being less than the power density of the second coating sub-section 232. This ensures that the heating temperature of the first coating sub-section 231 is less than the heating temperature of the second coating sub-section 232.

[0046] In some examples, the first far-infrared heating coating 23 may include two first coating sub-sections 231 and two second coating sub-sections 232. The two first coating sub-sections 231 are arranged in the same layer at intervals and have a symmetrical relationship, and the two second coating sub-sections 232 are arranged in the same layer at symmetrical intervals and have a symmetrical relationship. Each first coating sub-section 231 is provided corresponding to one eyeball, and each second coating sub-section 232 is arranged around a first coating sub-section 231 and has a U-shaped structure, and the openings of the U-shaped structures of the two second coating sub-sections 232 are arranged facing each other.

[0047] Here, the first electrode may include a first connecting segment 2212 and two first extension segments 2211. The first connecting segment 2212 connects the two first extension segments 2211, and the first connecting segment 2212 is configured to correspond to the nose. With the above configuration, the first electrode can be reasonably arranged so that the first electrode can drive and supply power to the two first coating sub-parts 231 and the two second coating sub-parts 232 respectively.

[0048] Here, the second electrode may include a second connecting segment 2223, two second extension segments 2221, and two end extension segments 2222. The second connecting segment 2223 connects to the two second extension segments 2221, and the end extension segments 2222 are connected to the second connecting segment 2223 via the second extension segments 2221. The second connecting segment 2223 is configured to correspond to the nose. With the above configuration, the second electrode can be rationally arranged so that the second electrode can drive and supply power to the two first coating sub-sections 231 and the two second coating sub-sections 232 respectively.

[0049] The material of the first conductive electrode layer 22 can be determined according to actual needs. It can be formed by printing or depositing and etching metal conductive pastes such as silver paste, copper paste, or metal composite conductive paste on the first base film 21. This application embodiment does not limit this.

[0050] The film structure of the second far-infrared electrothermal film 32 can be determined according to actual needs, and this application embodiment does not limit it. For example Figure 4 As shown, in some embodiments, the second far-infrared electrothermal film 32 may include a second base film 321, a second conductive electrode layer, a second far-infrared heating coating 323, and a second insulating layer 324, which are sequentially stacked. The material of the second base film 321 can be determined according to actual needs, and can be one of the following material types: polyimide film, PET film, fabric, etc. This application embodiment does not limit this.

[0051] The second conductive electrode layer includes a third electrode 3221 and a fourth electrode 3222 disposed at intervals within the same layer. The third electrode 3221 is disposed around the outer edge of the second far-infrared heating coating 323, forming a ring electrode that surrounds and contacts the second far-infrared heating coating 323. The third electrode 3221 has a notch, so that part of the outer edge of the second far-infrared heating coating 323 is exposed through the notch, and the fourth electrode 3222 can pass through the notch to contact the second far-infrared heating coating 323.

[0052] The material of the second conductive electrode layer can be determined according to actual needs. It can be formed by printing or depositing and etching a metal conductive paste, such as silver paste, copper paste, or metal composite conductive paste, on the second base film 321. This application embodiment does not limit this. The material of the second far-infrared heating coating 323 can be determined according to actual needs. It can be formed by printing a material such as graphene-based conductive ink. This application embodiment does not limit this.

[0053] The second insulating layer 324 covers the second far-infrared heating coating 323 to provide insulation protection for the second far-infrared heating coating 323. The type of the second insulating layer 324 can be determined according to actual needs, and can be, for example, an insulating coating, insulating tape, insulating heat-pressed film, etc., which is not limited in this embodiment.

[0054] like Figure 1 As shown, in some embodiments, the eye massager housing 1 may include a surface layer 11 and a flexible porous inner layer 12, which are stacked to enclose an inner cavity. The flexible porous inner layer 12 is configured to contact the wearer's eyes, and a first far-infrared electrothermal film 2 and a plurality of acupoint massage elements 3 are respectively disposed in the inner cavity.

[0055] The flexible porous inner layer 12 is made of a flexible porous material. The type of flexible porous material can be determined according to actual needs, such as composite mesh fabric, porous sponge, or perforated silicone, etc. This application embodiment does not limit this type. The flexible porous inner layer 12 can reduce the attenuation of far-infrared heat radiation during propagation, ensuring the radiation energy density used for eye physiotherapy. The material of the outer layer 11 can be determined according to actual needs, and can be one or a combination of several of the following materials: leather, fabric, silicone, plastic, etc. This application embodiment does not limit this type.

[0056] In some examples, multiple perforated grooves can be provided on the side of the surface layer 11 facing the flexible porous inner layer 12 and on the side of the flexible porous inner layer 12 facing the surface layer 11, respectively. These multiple perforated grooves are configured to correspond to the periorbital area, and the multiple acupoint massage elements 3 can be embedded one-to-one within these perforated grooves. Through this configuration, the position of the acupoint massage elements 3 can be defined by the perforated grooves, allowing the acupoint massage elements 3 to vibrate and massage within the range of the perforated grooves, ensuring the accuracy of acupoint massage. For example, a protrusion 121 is provided on the side of the flexible porous inner layer 12 away from the surface layer 11. The protrusion 121 and the perforated grooves in the flexible porous inner layer 12 are correspondingly configured and fit against the acupoint massage elements 3, allowing the acupoint massage elements 3 to better align and massage the periorbital acupoints through the protrusion 121.

[0057] In some examples, the far-infrared eye protection device may also include a flame-retardant layer 4, which is disposed between the surface layer 11 and the first far-infrared electrothermal film 2. The material of the flame-retardant layer 4 can be determined according to actual needs, and can be one or more types of flame-retardant materials such as flame-retardant coatings, flame-retardant cloths, and flame-retardant adhesives. This application embodiment does not limit this. By setting the flame-retardant layer 4, flame-retardant protection can be provided to prevent the surface layer 11 from being ignited in extreme cases, thereby effectively ensuring the safety of the wearer.

[0058] like Figure 1 and Figure 5As shown, in some embodiments, the far-infrared eye massager may further include a control compartment 5, which is disposed on the housing 1 of the eye massager. The control compartment 5 may be equipped with a control chip, a temperature control switch 51, a vibration control switch 52, a rechargeable battery, and a charging interface 53. The control chip may be embedded in the control compartment 5, while the temperature control switch 51, the vibration control switch 52, and the charging interface 53 may be disposed on the surface of the control compartment 5. The first far-infrared electrothermal film 2, the acupoint massage component 3, and the charging interface 53 are electrically connected to the rechargeable battery, while the temperature control switch 51 and the vibration control switch 52 are respectively connected to the control chip. On the one hand, users can adjust the heating temperature of the first far-infrared heating film 2 / second far-infrared heating film 32 and control the on / off state of the first far-infrared heating film 2 / second far-infrared heating film 32 through the temperature control switch 51; on the other hand, users can control the on / off state of the massage vibrator 31 and adjust parameters such as the vibration frequency of the massage vibrator 31 through the vibration control switch 52; and thirdly, the rechargeable battery can be charged through the charging interface 53 to meet charging needs. In some examples, the far-infrared eye massager can also be equipped with a music player to play music during massage therapy, providing a more comfortable user environment.

[0059] In some examples, the far-infrared eye massager can be set with multiple temperature levels to meet the therapeutic needs of different users and the same user in different states. For example, the far-infrared eye massager can be set with three temperature levels. Specifically, the first level is a sleep mode, with the temperature of the first far-infrared heating zone at 35℃ and the temperature of the second far-infrared heating zone and the second far-infrared heating film 32 at 38℃; the second level is an vitality mode, suitable for daily soothing and relaxation use, with the temperature of the first far-infrared heating zone at 39℃ and the temperature of the second far-infrared heating zone and the second far-infrared heating film 32 at 42℃; the third level is a warming care mode, suitable for use in winter or when the ambient temperature is low, with the temperature of the first far-infrared heating zone at 42℃ and the temperature of the second far-infrared heating zone and the second far-infrared heating film 32 at 45℃. Here, the switching and on / off control between different temperature levels can be achieved through the temperature control switch 51.

[0060] In some examples, the far-infrared eye massager can be set with multiple massage levels to meet the therapeutic needs of different users and the same user in different states. For example, the far-infrared eye massager can be set with two massage levels. Specifically, the first level is a health massage mode, in which two massage vibrators 31 vibrate alternately as a group to simulate the acupoints targeted by eye exercises. First, the massage vibrator 31 corresponding to the Zanzhu and Qingming acupoints vibrates to massage these acupoints, with a massage pattern of two sets of four eight-beat durations, corresponding to the first and second sections of the eye exercises. Then, the massage vibrator 31 corresponding to the Sibai acupoint vibrates to massage the Sibai acupoint, with a set of four eight-beat durations, corresponding to the third section of the eye exercises. Finally, the massage vibrator 31 corresponding to the Taiyang acupoint vibrates to massage the Taiyang acupoint, with a set of four eight-beat durations, corresponding to the fourth section of the eye exercises. During this process, the music player can play the music for the eye exercises. The second setting is the rhythmic massage mode. In this mode, the music player plays designated soothing instrumental music, and the massage vibrators 31 sequentially switch vibration zones according to the rhythm of the music. Here, the vibration control switch 52 can be used to switch between different massage settings and control the on / off state; for example, a long press on the vibration control switch 52 can activate the health massage mode, a short press can switch to the rhythmic massage mode, a short press can turn off the music, and a long press again can turn off the massage vibrators 31.

[0061] In some embodiments, the far-infrared eye massager may further include a wearing structure disposed on the outer surface of the eye massager housing 1 for use by the user to wear and secure it, such as by binding it to the wearer's head or hanging it on the wearer's ear. Figure 6 As shown, the wearing structure may include two elastic straps 61, which are respectively disposed at opposite ends of the eye massager housing 1. The elastic straps 61 have elastic stretching capability and can adjust their length to adapt to different users' head circumferences, making it convenient for users to wear.

[0062] In some examples, the end of the elastic strap 61 away from the eye massager housing 1 may be provided with Velcro 62. By providing Velcro 62, the two elastic straps 61 can be easily attached and fixed or quickly separated, increasing the convenience of wearing the device.

[0063] To verify the actual effectiveness of the far-infrared eye care device provided in this application embodiment, the applicant recruited volunteers for a six-week trial. Visual acuity data before and after use was collected and statistically analyzed, resulting in the visual acuity statistics in Tables 1 and 2. In this trial, the measured electrothermal radiation conversion efficiency of the first far-infrared electrothermal film 2 and the second far-infrared electrothermal film 32 of the provided far-infrared eye care device was 68%, obtained based on the test in Clause 6.21 of JG / T286-2010. As shown in Tables 1 and 2, the volunteers recruited for this trial were 30 primary school students and 30 middle school students; the primary school students were aged 8-12 years old, and the middle school students were aged 13-15 years old. Volunteers used the far-infrared eye care device provided in this application embodiment for 30 minutes daily, primarily using the second temperature setting (vitality mode) for far-infrared therapy and the first setting (eye exercise mode) for vibration massage. Visual acuity data was recorded every two weeks during the trial, and statistically analyzed after six weeks.

[0064] Table 1 shows the vision statistics of 30 primary school student volunteers. As shown in Table 1, under the logarithmic visual acuity chart standard, the volunteers' initial visual acuity data were: right eye 4.0–5.0, mean 4.4; left eye 4.0–5.0, mean 4.3; and binocular visual acuity 4.1–5.1, mean 4.5. After six weeks of using the far-infrared eye protection device, the volunteers' visual acuity data were: right eye 4.6–5.1, mean 4.8; left eye 4.5–5.1, mean 4.8; and binocular visual acuity 4.6–5.1, mean 4.9.

The comparison shows that the volunteers' visual acuity improved as follows: right eye 0.1–0.6, mean 0.5; left eye 0–0.7, mean 0.4; and binocular visual acuity 0.2–0.6, mean 0.4.

[0066] Based on the visual acuity data of 60 volunteers using the far-infrared eye protection device provided in this application embodiment, the overall visual acuity improvement rate was 98.3%, with a maximum improvement of 0.8. There were no significant differences between different age groups or genders. According to the actual test data, the far-infrared eye protection device provided in this application embodiment can effectively improve the user's vision, and the improvement is more significant for those with poorer initial vision.

[0067] To further compare and verify the actual usage effect of the far-infrared eye protection device provided in the embodiments of this application, the applicant conducted a comparative test using two eye protection devices from related technologies. One eye protection device uses a metal electrothermal film with a measured electrothermal radiation conversion efficiency of 51%, while the other uses a carbon electrothermal film with a measured electrothermal radiation conversion efficiency of 55%. Both measured electrothermal radiation conversion efficiencies were obtained based on the test in Clause 6.21 of JG / T 286-2010. In the comparative test, the applicant recruited volunteers to use the aforementioned eye protection devices for six consecutive weeks, and collected and statistically analyzed vision data before and after use, resulting in the vision statistics in Tables 3 and 4. As shown in Tables 3 and 4, the volunteers recruited for this comparative test were all middle school students aged 13-15; six volunteers used the metal electrothermal film eye protection device for 30 minutes daily, and the other eight volunteers used the carbon electrothermal film eye protection device for 30 minutes daily. During the actual testing process, visual acuity data was recorded every two weeks, and the data was statistically analyzed after six weeks.

The comparison shows that the volunteers' vision improved as follows: right eye 0–0.1, mean 0.1; left eye 0–0.1, mean 0.1; and both eyes 0–0.1, mean 0.1.

[0069] Table 4 shows the vision statistics of eight middle school student volunteers who used carbon electric heating film eye care devices. As shown in Table 4, the volunteers' initial vision data were: right eye 4.0–4.4, mean 4.2; left eye 4.1–4.3, mean 4.2; and both eyes 4.0–4.4, mean 4.3. After six weeks of using the carbon film eye care devices, the volunteers' vision data were: right eye 4.1–4.5, mean 4.3; left eye 4.2–4.5, mean 4.3; and both eyes 4.2–4.5, mean 4.4. The comparison shows that the volunteers' vision improved as follows: right eye 0–0.2, mean 0.1; left eye 0.1–0.2, mean 0.1; and both eyes 0–0.2, mean 0.1.

[0070] Based on the combined vision data of the 14 volunteers using the eye protection device in the relevant technology, the eye protection device in the relevant technology did not have a significant effect on improving the volunteers' vision.
