Technical Field

[0001] This utility model relates to an electronic bracelet, specifically an electronic bracelet for ultraviolet detection. Background Technology

[0002] Scientific research shows that moderate sun exposure is beneficial to health, such as promoting vitamin D synthesis and calcium absorption, improving mood, and regulating the biological clock. However, if the ultraviolet rays in the sun are too strong, excessive sun exposure may lead to sunburn, skin pigmentation, and other problems.

[0003] Currently, many electronic fitness trackers and smartwatches are equipped with ultraviolet (UV) sensors to accurately detect the intensity of ambient UV radiation and convert the data into an easily understandable UV index (UVI). When the UVI exceeds a set value, the wearer is alerted through vibration, light, or sound. However, these electronic trackers rely entirely on sensors to monitor UV radiation, making them highly susceptible to battery life issues. When the tracker or watch shuts down due to low battery, it cannot provide UV intensity detection, which needs improvement. Utility Model Content

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-5 In this embodiment of the present invention, an electronic bracelet for ultraviolet detection includes a frame 1, within which an electronic bracelet body 4 is detachably installed. The top surface of the electronic bracelet body 4 is provided with a display screen 19 and an ultraviolet sensor 20. The electronic bracelet body 4 also contains a controller, a battery, a vibrator motor, and a speaker. The electronic bracelet body 4 can also communicate with a smartphone via a Bluetooth module, and the smartphone has application software compatible with the electronic bracelet body 4 installed. An ultraviolet-sensitive color-changing silicone strap 2 is fixedly sleeved on the outer wall of the frame 1. The ultraviolet-sensitive color-changing silicone strap... Photochromic powder (photosensitive color-changing powder) is added to the silicone. After absorbing ultraviolet light of a specific wavelength, its molecular structure undergoes a reversible change, resulting in a color change. After the ultraviolet light disappears, it returns to its original state. Moreover, when the ultraviolet photosensitive color-changing silicone is exposed to ultraviolet light of the same intensity, its color will not deepen indefinitely. Its color change is a reversible process that reaches a dynamic equilibrium. The outer surface of the ultraviolet photosensitive color-changing silicone watch strap 2 is printed with a colorimetric card 3. The colorimetric card 3 is composed of several different color blocks 21. The colors of the several color blocks 21 belong to the same category, but the color depth of each color block 21 is different.

[0021] By adopting the above-described solution, this utility model allows the electronic bracelet body 4 to detect the ambient ultraviolet radiation intensity via the ultraviolet sensor 2 during normal use, converting the data into an easily understandable UV index (UVI). When the UVI exceeds a set value, it can alert the user through various means such as screen display, light, and vibration. Furthermore, users can edit their personal information on a smartphone application, including details such as skin sensitivity, age, gender, health status (current vitamin D deficiency), and medication use. The application can also push daily recommendations for suitable sun exposure times based on season and weather. If prolonged sun exposure may cause harm, both the phone and the electronic bracelet body 4 will issue a warning.

[0022] The electronic bracelet body 4 and the application software can be used as follows:

[0023] Time: 9:25 a.m., Location: Open space downstairs from the company building, Duration: 20 minutes;

[0024] With a skin sensitivity rating set to 5, and a UVA+B index of 1 after 20 minutes of sun exposure, the threshold was not reached. Neither the phone nor the main body of the electronic bracelet issued a warning, and the user could still enjoy the sun.

[0025] Time: 1:30 PM, Location: Open space downstairs from the company building, Duration: 60 minutes;

[0026] With a skin sensitivity value set to 5, and after 60 minutes of sun exposure between 1:30 PM and 2:30 PM, the UVA+B index was 3. This did not reach the threshold, and neither the phone nor the electronic bracelet issued any warnings; the user could still enjoy the sun.

[0027] Accumulate a total of 80 minutes of safe sun exposure throughout the day to meet today's requirements, record your personal profile, and complete your sun protection record.

[0028] Furthermore, through the setting of the UV photosensitive color-changing silicone strap 2, when the UV photosensitive color-changing silicone strap 2 is exposed to sunlight, it will also change color. By comparing the color of the UV photosensitive color-changing silicone strap 2 with the various filaments 21 on the color chart 3, the user can quickly understand the current range of the UV index, thus making it convenient to understand the UV intensity when the main body 4 of the electronic bracelet is low on power, making it more convenient to use.

[0029] Specific combination Figure 5 In one embodiment of this utility model, several color blocks 21 are distributed sequentially on the UV photosensitive color-changing silicone watch strap 2 according to the color depth change, thereby facilitating comparison by the user.

[0030] Specific combination Figures 1-3In one embodiment of this utility model, a locking block 5 is fixedly provided on the inner wall of one end of the frame 1, and a first slot 6 adapted to the locking block 5 is opened on the outer wall of the electronic bracelet body 4. The first slot 6 is located inside the locking block 5. A locking mechanism is slidably installed on the bottom inner wall of the frame 1 at the end away from the frame 1. A groove 7 is opened at the bottom of the electronic bracelet body 4 corresponding to the locking mechanism. A locking rod 8 is fixedly installed in the groove 7 and is adapted to the locking mechanism.

[0031] Based on the previous embodiment, further, the bottom inner wall of the frame 1 is provided with a sliding groove 9, and the bottom of the frame 1 is provided with an opening groove 13 communicating with the sliding groove 9. The locking mechanism includes a sliding plate 10 that is slidably installed in the sliding groove 9. A hook 11 is fixedly provided at the top of the sliding plate 10 corresponding to the groove 7. A second slot 12 adapted to the hook 8 is provided on the outer wall of the hook 11. The hook 8 is located in the second slot 12. A lever 15 and a spring 16 are provided in the opening groove 13. The top of the lever 15 is fixedly connected to the sliding plate 10. A guide rod 14 is fixedly installed in the opening groove 13. The lever 15 is slidably sleeved on the guide rod 14 through a stepped hole. The spring 16 is sleeved on the guide rod 14, and one end of the spring 16 is located in the stepped hole.

[0032] By moving the slider 10 by shifting the lever 15, the hook 11 can be disengaged from the lever 8, thus facilitating the disassembly and assembly of the electronic bracelet body 4 within the frame 1. During the disassembly and assembly process, there is no need to cause significant deformation of the UV-sensitive color-changing silicone strap 2, thereby effectively preventing the UV-sensitive color-changing silicone strap 2 from cracking due to frequent disassembly and assembly of the electronic bracelet body 4. The guide rod 14 improves the stability of the movement of the lever 15 and the slider 10 on the frame 1, while the spring 16 ensures the stability of the engagement between the hook 11 and the lever 8.

[0033] Specific combination Figure 2 and Figure 3 In one embodiment of the present invention, a first magnet 17 is fixedly embedded in the bottom surface of the electronic bracelet body 4 at one side of the groove 7, and a second magnet 18 is fixedly embedded in the top surface of the slide plate 10 at the corresponding position of the first magnet 17. The polarities of the outer surfaces of the first magnet 17 and the second magnet 18 are opposite.

[0034] With the cooperation of the first magnet 17 and the second magnet 18, when the lever 8 is located in the second slot 12 on the hook 11, the first magnet 17 and the second magnet 18 are aligned and attracted to each other, thereby improving the reliability of the electronic bracelet body 4 installed in the frame 1. When the sliding plate 10 is moved by the toggle block 15 so that the lever 8 is disengaged from the second slot 12, the first magnet 17 and the second magnet 18 will be misaligned. At this time, the two magnets will repel each other, pushing one end of the electronic bracelet body 4 out of the frame 1, thus making it easier to remove the electronic bracelet body 4 from the frame 1.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
