[0057] Based on the above embodiment:

[0058] Figure 6 A schematic diagram of the structure of a charging circuit provided in this application;

[0059] In some embodiments, the charging circuit 5 includes a battery, a first processor U1 and a first diode D1;

[0060] The anode of the first diode D1 is connected to the charging port 4, and the cathode of the first diode D1 is respectively connected to the detection end of the first processor U1 and the positive electrode of the battery. The detection end is used to charge the battery with the electric energy input by the charging port 4 when the charging port 4 is connected to the power supply. The first diode D1 is used to prevent reverse.

[0061] When the input voltage VCC exceeds the power supply low voltage detection threshold and pin 8 of the first processor U1 is high, the first processor U1 begins charging the battery through pin 8. If the battery voltage BAT+ falls below 3V, constant current mode is used for charging. When the battery voltage approaches 4.2V, the charging current gradually decreases, entering constant voltage mode. The charging cycle ends when the charging current decreases to the end-of-charge threshold, which is 10% of the constant current charging current. A new charging cycle automatically begins when the battery voltage drops below the recharge threshold. The first processor U1's internal high-precision voltage reference, error amplifier, and resistor divider network ensure that the battery-side regulated voltage remains within 1%, meeting the precise charging requirements of lithium-ion and lithium-polymer batteries. If the input voltage drops below the battery voltage or falls below the battery voltage, the charger enters a low-power sleep mode, consuming less than 3uA of current at the battery end, thereby extending standby time. If pin 8 of the first processor U1 is connected low, the charger stops charging.

[0062] In some embodiments, the charging circuit 5 further includes a first indicator light RG1 and a second indicator light GG2;

[0063] A first end of the first indicator light RG1 is connected to the charging port 4, and a second end of the first indicator light RG1 is connected to the first output end of the first processor U1. The first indicator light RG1 is configured to emit light to indicate that the battery is in a charging state.

[0064] A first end of the second indicator light GG2 is connected to the charging port 4 , and a second end of the second indicator light GG2 is connected to the second output end of the first processor U1 . The second indicator light GG2 is configured to emit light to indicate that battery charging is complete.

[0065] When pin 8 of the first processor U1 is high, the first processor U1 begins charging the battery through pin 8. Pin 7 of the first processor U1 outputs a low level, and the first indicator RG1 illuminates, indicating that charging is in progress. When the charging current decreases to the charge end threshold, the charging cycle ends, pin 7 of the first processor U1 outputs a high-impedance state, the first indicator RG1 turns off, pin 6 of the first processor U1 outputs a low level, and the second indicator GG2 illuminates.

[0066] Figure 7 A schematic diagram of the arrangement of photon lamp beads provided in this application;

[0067] In some embodiments, the photon lamp beads 7 are light-emitting diodes of various colors;

[0068] The photon lamp beads 7 are arranged in m rows×n columns, and any two lamp beads of the same color are neither adjacent in the same row nor in the same column.

[0069] This product uses a combination of optical lamp beads with four wavelengths: 640-650nm, 580-590nm, 450-460nm, and 940-950nm. A total of 150-160 optical lamp beads are evenly arranged. In addition to the 640-650nm and 580-590nm staggered arrangement in the vertical arrangement, 450-460nm or 940-950nm lamp beads are also added to each vertical arrangement. These two optical lamp beads do not appear in the same vertical arrangement, and are staggered within the row.

[0070] Each wavelength band of optical lamp beads has an independent control drive circuit to achieve the control of operation and irradiation power. Through the preset program of the control chip, different wavelengths are combined into a function, and the output power of different wavelengths is controlled at the same time. Under different functional modes, the photon energy emitted by the optical lamp beads varies according to the preset mode function requirements. Function combination: When mode function 1 is selected, 640-650nm, 580-590nm, and 940-950nm are combined into a group, and the function proportion of each band is 45%, 30%, and 25% respectively. In addition, the power will be reduced by 50-60% at the same time during the interval of 20-30 seconds. After the time is up, the full power will be restored and the power will drop to 50-60% after 20-30 seconds. The combination of light is targeted at different functions. If it is for whitening, 640-650nm and 580-590nm will increase energy to promote metabolism. If it is for acne and inflammation, 450-460nm and 940-950nm will be used to reduce inflammation on the skin surface. The time interval is to allow the skin to contract, so that metabolism can be better.

[0071] In some embodiments, the multiple colors of LEDs include at least two of a blue light emitting diode, an infrared light emitting diode, a yellow light emitting diode, and a red light emitting diode.

[0072] Lamp beads of different bands (B blue light, HW infrared light, Y yellow light, H red light) are combined to form different functions.

[0073] Specifically, it includes six functions, namely P1: acne care, P2: rejuvenating and lightening spots, P3: moisturizing and moisturizing, P4: after-sun repair, P5: soothing skin, and P6: smart exclusive.

[0074] Acne treatment is 70% 460nm light + 30% 630nm light, rejuvenating and lightening is 60% 630nm light + 30% 590nm light + 10% 940nm light, hydrating and moisturizing is 60% 590nm light + 30% 630nm light + 10% 940nm light, after-sun repair is 77.5% 630nm light + 17.5% 590nm light + 5% 940nm light, and skin soothing is 60% 590nm light + 40% 460nm light.

[0095] The principle of the lithium battery protection chip mainly involves protecting the battery from over-discharge, over-charge, over-current and output short-circuit protection. The working principle of the lithium battery protection chip relies on a protection board composed of a control IC (U2), a switch tube (MOS tube) and some other micro-capacitors and micro-resistors. The function of the control IC is to protect the battery.

The MOS tube acts as a switch, and its switching state is controlled by the control IC. This protection function is usually completed by the protection circuit board and PTC. The protection board is composed of electronic circuits and can accurately monitor the voltage of the battery cell and the current of the charging and discharging circuit in an environment of -40 to +85. Specific protection functions include:

[0096] Overcharge protection: When the battery voltage exceeds a set value (e.g., 4.25-4.35V), charging stops through a series of electronic components to prevent overcharging. Charging resumes when the battery voltage returns to a certain value.

[0097] Over-discharge protection: When the battery is discharged to a certain voltage (such as 2.5V), the control IC sends a command to cut off the MOS tube and disconnect the circuit to prevent the battery from over-discharge.

[0098] Overcurrent protection: When the load suddenly decreases, causing the current to suddenly increase, the control IC issues a command to cut off the MOS tube by sampling the voltage generated by the sudden increase in current, disconnecting the circuit and protecting the battery.

[0099] Short-circuit protection: By detecting a short-circuit condition, the control IC will also issue a command to disconnect the circuit to protect the battery from damage.

[0100] Furthermore, the BMS (Battery Management System) plays a crucial role in protecting lithium-ion batteries. It intelligently manages and maintains each battery cell, preventing overcharging and over-discharging, extending battery life, and monitoring battery status. The BMS determines the status of the entire battery system by monitoring the status of each cell in the power battery pack. Based on this status, the BMS makes corresponding control adjustments and implements strategies for the power battery system, managing the charge and discharge of the power lithium-ion battery system and its individual cells to ensure safe and stable operation.

[0101] BAT+ is the positive electrode of the battery, BAT- is the negative electrode of the battery, and C3 and R5 are used for filtering.
