[0040] According to one embodiment of the present application, referring to Figure 1-Figure 3 As shown, the charger provided by the present application includes: a housing 1, a circuit board 2, a charging structure 3, and an indication structure 4. The housing 1 has a first wall 5 and a second wall 6 opposite to each other; the circuit board 2 is arranged in the housing 1; the charging structure 3 includes a charging electrode 7 and a charging line 8, the charging electrode 7 has a connection end 9 and a charging end 10, the connection end 9 of the charging electrode 7 is electrically connected to the circuit board 2, and the charging end 10 of the charging electrode 7 is passed through the outside of the first wall 5 of the housing 1 and is used to electrically connect to a phototherapy device (not shown in the figure); one end of the charging line 8 is electrically connected to the circuit board 2; the indication structure 4 is provided on the second wall 6 of the housing 1, and the indication structure 4 is electrically connected to the circuit board 2, and the indication structure 4 is used to indicate the charging information of the phototherapy device.

[0041] In this embodiment of the present application, the charger of the present application not only provides a charging function, but also adds an indicator structure 4 to display charging information, which can enhance the user experience and increase the safety of use. Specifically:

[0042] The housing 1, serving as the carrier of the entire charger, primarily consists of two opposing walls: a first wall 5 and a second wall 6. For example, the first wall 5 can be the bottom wall, through which the charging electrodes 7 extend, while the second wall 6 can be the top wall, on which the indicator structure 4 is mounted for user convenience.

[0043] The circuit board 2 is one of the core components of the charger. It is responsible for controlling the direction, intensity and other parameters of the charging current, and forms an electrical connection with the charging structure 3 and the indicator structure 4 to realize the charging process of the phototherapy device.

[0044] The charging structure 3 primarily consists of a charging electrode 7 and a charging cable 8. One end of the charging electrode 7 is connected to the circuit board 2, and the other end passes through the first wall 5 of the housing 1 to contact the charging port of the phototherapy device. The charging cable 8 also has one end connected to the circuit board 2 and the other end, which can be a USB plug. The USB plug plugs into a charging head, which in turn plugs into an outlet. It will be appreciated that the charging electrode 7 includes a positive electrode and a negative electrode to facilitate charging.

[0045] The indicator structure 4 is located on the second wall 6 of the shell 1 and is electrically connected to the circuit board 2. It can be used to display the charging status information of the phototherapy device, such as current size, voltage level, battery charging progress, temperature of the circuit board 2, etc.

[0046] When the user connects the charger's charging cable 8 to an outlet and places the phototherapy device's charging port in contact with the charger's charging electrode 7, circuit board 2 begins controlling the flow of current to the phototherapy device via charging electrode 7 and charging cable 8. Simultaneously, circuit board 2 monitors various parameters during the charging process and displays this information to the user via indicator structure 4, allowing the user to intuitively understand the current charging status, providing an early warning and improving charging safety.

[0047] Therefore, the charger provided in the embodiment of the present application can effectively improve charging safety and user experience.

[0048] According to one embodiment of the present application, referring to Figure 2 and Figure 3 As shown, a sensor 11 is electrically connected to the circuit board 2, and the sensor 11 is used to detect electrical parameters of the phototherapy device when it is charging and / or the temperature of the circuit board 2 when the phototherapy device is charging.

[0049] The indication structure 4 includes a display screen 12 , which is provided on the second wall 6 of the housing 1 and is electrically connected to the circuit board 2 . The display screen 12 is used to display charging information of the phototherapy device, including electrical parameters and / or temperature.

[0050] In this embodiment of the present application, a sensor 11 is added to the circuit board 2 to monitor the electrical parameters of the phototherapy device (such as voltage, current, and battery level) during charging, as well as the temperature of the circuit board 2. This helps to monitor the charging status in real time and prevent overcharging, overheating, etc.

[0051] For example, the sensor 11 may include a voltage sensor, a current sensor, a battery charge sensor, and a temperature sensor, etc. The voltage sensor is used to detect the charging voltage, the current sensor is used to detect the charging current, the battery charge sensor is used to detect the battery charge of the phototherapy device, and the temperature sensor is used to detect the temperature of the circuit board 2 during charging.

[0052] The indicator structure 4 includes a display screen 12, which is arranged on the second wall 6 of the housing 1 and connected to the circuit board 2. In this way, the display screen 12 can receive data from the circuit board 2 and convert it into visual information to present to the user.

[0053] The display 12 can display the charging information of the light therapy device, including but not limited to electrical parameters such as voltage, current, and battery level. In addition, it can also display the temperature of the circuit board 2, allowing the user to understand the working status of the device at any time.

[0054] If the sensor 11 detects any abnormal situation, such as excessive temperature or excessive current, the display screen 12 can immediately send a warning signal to the user. This can effectively prevent potential safety hazards and ensure user safety.

[0055] Therefore, through the information provided by the display screen 12 in the embodiment of the present application, the user can more clearly understand the charging status of the phototherapy device, avoiding the problem of the user having to constantly check whether the device is fully charged in the traditional charging method.

[0056] In addition, the early warning function can promptly remind users of possible problems, such as equipment damage or even fire risks caused by overheating, allowing users to take appropriate measures to ensure the safety of the charging process.

[0057] According to one embodiment of the present application, referring to Figure 2 and Figure 3 As shown, the indicating structure 4 further includes an indicator light 13 , which is disposed on the second wall 6 of the housing 1 and is electrically connected to the circuit board 2 . The indicator light 13 is used to indicate charging information of the phototherapy device.

[0058] In this example of the present application, in addition to the display screen 12, an indicator light 13 is also provided on the second wall 6 of the shell 1, and the indicator light 13 is connected to the circuit board 2 and can change its color or flashing mode according to the data received by the circuit board 2.

[0059] Specifically, the indicator light 13 can very intuitively inform the user whether the battery of the light therapy device is fully charged. For example, when the battery is fully charged, the indicator light 13 is long green.

[0060] The indicator light 13 can also be used to warn the temperature of the circuit board 2. If the temperature of the circuit board 2 is too high, the indicator light 13 flashes yellow to remind the user that there may be a risk of overheating and that measures need to be taken to reduce the temperature.

[0061] In the event of voltage or current overload, the indicator light 13 flashes red to remind the user that there may be an overload problem and that the power supply needs to be disconnected or the charging environment needs to be adjusted in time.

[0062] Therefore, the embodiment of the present application forms a multi-level early warning system through the combined use of the display screen 12 and the indicator light 13. Even if the user fails to notice the information on the display screen 12, the indicator light 13 can serve as a second line of defense, ensuring that the user can promptly detect and handle abnormal conditions during the charging process, thereby effectively improving charging safety.

[0063] According to one embodiment of the present application, referring to Figure 2 As shown, the indicator light 13 is arranged around the display screen 12.

[0064] Specifically, the indicator light 13 is designed to surround the display screen 12, which means that it is arranged along the edge of the display screen 12. Such a design not only saves space and is conducive to the overall miniaturization of the charger, but also can utilize the area around the display screen 12 to enhance the visual effect.

[0065] Furthermore, through programming control, the indicator light 13 can display a dynamic effect similar to a "marquee". This effect can not only attract the user's attention, but also convey information in a more vivid and interesting way.

[0066] According to one embodiment of the present application, referring to Figure 1-Figure 3 As shown, the housing 1 includes: a bottom shell 14 and a top cover 15 , the bottom shell 14 has a first wall 5 ; the top cover 15 is detachably covered on the bottom shell 14 , and the top cover 15 has a second wall 6 .

[0067] In this embodiment of the present application, the bottom case 14 serves as the base of the entire charger, providing a stable support and having a first wall 5 through which a portion of the charging electrode 7 extends to the outside. The bottom case 14 has a space inside for fixing the circuit board 2 and other components.

[0068] The top cover 15 cooperates with the bottom shell 14 and can be conveniently covered on the bottom shell 14, and has a second wall 6. The detachable design of the top cover 15 allows it to be easily opened or closed during assembly and maintenance, making it easy to inspect or replace internal components.

[0069] According to one embodiment of the present application, a first sealing member (not shown) is provided at the connection between the bottom shell 14 and the top cover 15. The first sealing member can be a sealing ring. Such a design can effectively improve the sealing and waterproofness, thereby improving charging safety.

[0070] According to one embodiment of the present application, referring to Figure 3 As shown, the bottom shell 14 further has a third wall 16 disposed between the first wall 5 and the second wall 6 . One end of the charging cable 8 passes through the third wall 16 of the bottom shell 14 and is electrically connected to the circuit board 2 .

[0071] In this embodiment of the present application, the bottom shell 14 includes not only the first wall 5, but also a third wall 16 disposed between the first wall 5 and the second wall 6 of the top cover 15. This three-dimensional design makes the entire housing 1 of the charger a closed frame structure.

[0072] One end of the charging cable 8 passes through the third wall 16 and connects to the circuit board 2. This means that the charging cable 8 can enter the interior of the housing 1 from the side, rather than from the top or bottom. This layout prevents the charging cable 8 from interfering with the operation of other components, thereby achieving a compact design.

[0073] Furthermore, a cable hole is provided on the third wall 16 of the bottom housing 14, and a sealing sleeve 17 is provided in the cable hole. During assembly, one end of the charging cable 8 passes through the sealing sleeve 17 and enters the housing 1 to electrically connect with the circuit board 2. By adding appropriate sealing measures in the cable hole, the sealing and waterproof performance of the device can be further improved.

[0074] According to one embodiment of the present application, referring to Figure 3 As shown, the second wall 6 of the top cover 15 is provided with a receiving opening 18 adapted to the indicating structure 4 , the side wall of the receiving opening 18 is provided with a step portion 19 , the indicating structure 4 is provided in the receiving opening 18 , and the indicating structure 4 is detachably connected to the step portion 19 .

[0075] In this embodiment of the present application, a receiving opening 18 is provided on the second wall 6 of the top cover 15. This receiving opening 18 is used to accommodate the indicator structure (such as the display screen 12 and the indicator light 13). The design of the receiving opening 18 allows the indicator structure 4 to be embedded, thereby making the entire device surface smoother and more neat in appearance.

[0076] The sidewall of the receiving opening 18 is provided with a step 19, on which the indicator structure 4 can be mounted, and in a detachable manner. Such a design ensures that the indicator structure 4 is firmly fixed in the receiving opening 18 while being easy to assemble and disassemble.

[0077] According to one embodiment of the present application, the indicating structure 4 is provided with a first snap-fitting structure, and the step portion 19 is provided with a second snap-fitting structure. One of the first snap-fitting structure and the second snap-fitting structure is a snap-fitting slot, and the other is a snap-fitting buckle, and the snap-fitting buckle is snap-fitted to the snap-fitting slot.

[0078] For example, a buckle is provided at the bottom of the display screen 12 and the indicator light 13, and a corresponding slot is provided on the step portion 19. During assembly, the buckle at the bottom of the display screen 12 and the indicator light 13 is inserted into the corresponding slot of the step portion 19, thereby realizing the assembly of the indication structure 4.

[0079] According to one embodiment of the present application, referring to Figure 3As shown, a second sealing member 20 is provided between the indicator structure 4 and the step portion 19. The second sealing member 20 may be a sealing ring. This design can effectively improve the sealing and waterproof performance of the charger, thereby improving charging safety.

[0080] According to one embodiment of the present application, referring to Figure 3 As shown, a mounting frame 21 is provided in the housing 1 , and the circuit board 2 is detachably connected to the mounting frame 21 .

[0081] For example, the mounting bracket 21 is fixed in the bottom case 14 , and the circuit board 2 is fixed to the mounting bracket 21 by screws.

[0082] Alternatively, a slot is provided on the edge of the circuit board 2 and a buckle is provided on the mounting frame 21. During assembly, the slot of the circuit board 2 is buckled onto the buckle of the mounting frame 21, thereby achieving rapid assembly of the circuit board 2.

[0083] According to one embodiment of the present application, referring to Figure 3 As shown, the first wall 5 of the housing 1 is provided with a positioning hole 22 , and the charging end 10 of the charging electrode 7 is passed through the positioning hole 22 .

[0084] In this embodiment of the present application, a positioning hole 22 is provided on the first wall 5 of the housing 1, mainly for fixing the position of the charging electrode 7. After the charging end 10 of the charging electrode 7 passes through the positioning hole 22, it can be ensured that it will not move or become loose during use.

[0085] The charging electrode 7, secured by the positioning hole 22 in the embodiment of the present application, maintains a stable position during charging, reducing the risk of charging interruptions due to shaking. Furthermore, the design of the positioning hole 22 facilitates insertion of the charging electrode 7 into the correct position during assembly, reducing the possibility of assembly errors and improving production efficiency.

[0086] Furthermore, in order to further improve the sealing and waterproof performance of the charger, a sealing ring (not shown in the figure) may be provided between the charging end 10 of the charging electrode 7 and the positioning hole 22 .

[0087] The above is only a preferred embodiment of the present application and is not intended to limit the embodiments of the present application.
