[0056] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0057] In an exemplary embodiment, Figure 1 As shown, a power supply device is provided, which includes a battery pack 110, a first power supply module 120, a second power supply module 130 and a third power supply module 140; when the battery pack 110 is in a discharging state, the first power supply module 120 is used to convert the battery voltage of the battery pack 110 and then supply power, the second power supply module 130 is used to perform a secondary conversion on the voltage converted by the first power supply module 120 and then provide power to the load part, and the third power supply module 140 is used to perform a secondary conversion on the voltage converted by the first power supply module 120 and then provide power to the auxiliary part; when the battery pack 110 is in a charging state, the first power supply module 120 is used to convert the external voltage of the external power supply and then supply power, and the third power supply module 140 is used to provide the external voltage to the auxiliary part.

[0058] For example, the power supply device provided by the present application can be applied to a phototherapy mask product, which may include a load part for performing phototherapy care, and the components of this part may include a phototherapy lamp, a phototherapy lamp driver, and an infrared sensor, etc. It may also include an auxiliary part for assisting the operation of the phototherapy mask product, and the components of this part may include a communication component and an interactive component, etc.

[0059] It can be understood that in the above-mentioned phototherapy mask product, the load part can be set independently of other parts, that is, the load part is implemented in the form of a mask, and the other parts are implemented in the form of a remote control, and the remote control and the mask can be connected through an interface set on the remote control. At the same time, the interface set on the remote control can also be used to connect an adapter to connect the external voltage of the external power supply to charge the battery pack 110 on the remote control. The load part and other parts can also be set in one body, that is, the whole is implemented in the form of a phototherapy mask. At the same time, the phototherapy mask can also be provided with an interface for connecting the adapter to obtain the external voltage to charge and power the battery pack 110 of the phototherapy mask.

[0060] In addition, the phototherapy mask product may also include a control part, and the controller of the control part may be connected to the various components of the load part and the auxiliary part to realize the control of the operating status of each component in the phototherapy mask product. It can be understood that the controller is the control center of the phototherapy mask product, which can be a control chip or control circuit board arranged on the main body of the phototherapy mask, or an external control system based on wireless communication. The external control system can be implemented through devices such as terminals or servers. The terminals can be but are not limited to various personal computers, smart phones, tablet computers, Internet of Things devices and portable wearable devices. Internet of Things devices can be smart speakers, smart car-mounted devices, etc. Portable wearable devices can be smart watches, smart bracelets, etc. The server can be implemented as an independent server or a server cluster composed of multiple servers.

[0061] Specifically, the battery pack 110 in the power supply device is composed of a plurality of lithium batteries connected in parallel. It is understood that the battery pack 110 can operate in a charging state or a discharging state. When the battery pack 110 is in a normal discharging state, the battery voltage of the battery pack 110 is 3.7V. When the battery voltage of the battery pack 110 is lower than the low voltage threshold, it indicates that the battery pack 110 is undervoltage and needs to be switched to a charging state for charging.

[0062] Furthermore, the power supply device of the present application is designed with three power supply modules to provide diversified and stable power supply for the phototherapy mask product, ensuring that it does not cause overall fluctuations and instability when powering on or off.

[0063] Among them, when the battery pack 110 is in a discharging state, each power supply module transfers the battery voltage to the device load side; when the battery pack 110 is in a charging state, each power supply module transfers the external voltage of the external power supply connected to the adapter to the battery pack 110 and the device load that needs power.

[0064] The first power supply module 120 is a power supply module directly connected to the battery pack 110, and is used to convert the battery voltage of the battery pack 110 and then provide power. It can be understood that the way in which the first power supply module 120 performs voltage conversion can be adjusted according to the actual power supply demand. For example, when the battery pack 110 is in a discharging state, the first power supply module 120 can provide power after boosting the battery voltage of the battery pack 110, or it can provide power to the control part after stepping down and stabilizing the battery voltage of the battery pack 110. When the battery pack 110 is in a charging state, the first power supply module 120 can provide power to the battery pack 110 after stepping down the external voltage of the external power supply, and to the control part for use.

[0065] The second power supply module 130 is a power supply module connected to the first power supply module 120, and is used to perform a secondary conversion on the voltage converted by the first power supply module 120 and then provide power to the load part. It can be understood that the way the second power supply module 130 performs voltage conversion can be determined according to the voltage requirement of the load part. Taking the power supply to the infrared sensing sensor as an example, its voltage requirement is 1.8V, and then the second power supply module 130 can perform a secondary conversion on the voltage converted by the first power supply module 120 to obtain a 1.8V power supply voltage, which is provided to the infrared sensing sensor for use. It can be understood that when the battery pack 110 is in a charging state, the functional components of the load part will generally stop being used, so the second power supply module 130 may not work when the battery pack 110 is in a charging state.

[0066] The third power supply module 140 is also a power supply module connected to the first power supply module 120, and is used to provide power supply to the auxiliary part after the voltage converted by the first power supply module 120 is converted twice. It can be understood that the way in which the third power supply module 140 performs voltage conversion can be determined according to the voltage requirement of the auxiliary part. Taking the power supply to the Bluetooth communication component as an example, its voltage requirement is 5V, and then the third power supply module 140 can perform a secondary conversion on the voltage converted by the first power supply module 120 to obtain a 5V power supply voltage, which is provided to the Bluetooth communication component for use. It can be understood that when the battery pack 110 is in a charging state, the third power supply module 140 can also obtain the external voltage of the external power supply to realize power supply. At the same time, when the external voltage of the external power supply is the same as the voltage requirement of the auxiliary part, the third power supply module 140 can directly connect the external voltage of the external power supply without performing a secondary conversion on the voltage to realize power supply.

[0067] It can be understood that the specific circuit structures and devices that can be used by the first power supply module 120, the second power supply module 130 and the third power supply module 140 are not fixed and can be determined according to actual power supply requirements. For example, each power supply module can be implemented by a low-voltage linear regulator, or by a DC-DC converter, or by other power supply devices that can perform voltage conversion or voltage stabilization.

[0068] In the above-mentioned power supply device, when the battery pack is in a discharging state, the first power supply module is used to convert the battery voltage of the battery pack and then supply power, the second power supply module is used to perform a secondary conversion on the voltage converted by the first power supply module and then provide power to the load part, and the third power supply module is used to perform a secondary conversion on the voltage converted by the first power supply module and then provide power to the auxiliary part; when the battery pack is in a charging state, the first power supply module is used to convert the external voltage of the external power supply and then supply power, and the third power supply module is used to provide the external voltage to the auxiliary part. The present application is designed with multiple power supply modules for power supply conversion, which not only meets the high-standard charging and discharging requirements of the battery pack, but also can provide power supply voltages of different specifications for various components in the phototherapy mask, and can achieve stable power supply to the phototherapy mask.

[0069] In an exemplary embodiment, Figure 2 and Figure 3As shown, the first power supply module 120 includes a first voltage regulator 121 and a first voltage converter 122; when the battery pack 110 is in a discharging state, the first voltage regulator 121 is used to stabilize the battery voltage of the battery pack 110 and provide it to the control part for power supply, and the first voltage converter 122 is used to convert the battery voltage of the battery pack 110 and provide overall power supply; when the battery pack 110 is in a charging state, the first voltage converter 122 is used to convert the external voltage of the external power supply to charge the battery pack 110, and the first voltage regulator 121 is used to provide the voltage converted by the first voltage converter 122 to the control part for power supply.

[0070] Specifically, the first voltage converter 122 is DCDC1. Figure 2 , when the battery pack 110 is in a discharging state, one end of the first voltage converter 122 is connected to the positive pole of the battery pack 110, and the other end is connected to other power supply modules. The first voltage converter 122 can provide overall power supply after converting the battery voltage of the battery pack 110, that is, boosting the 3.7V battery voltage to the voltage of the overall power supply. Correspondingly, in order to achieve overall power supply for all components of the phototherapy mask, the voltage value after the boost by the first voltage converter 122 needs to be based on the highest power supply requirement in the phototherapy mask. Taking the power supply voltage (11V) required by the phototherapy lamp of the phototherapy mask as an example, the first voltage converter 122 is used to boost the 3.7V battery voltage to 11V.

[0071] Reference Figure 3 When the battery pack 110 is in a charging state, one end of the first voltage converter 122 is connected to the positive electrode of the battery pack 110, and the other end is connected to other power supply modules, and is also connected to an external power source through an interface. The first voltage converter 122 can be connected to an adapter through an interface, and the adapter converts the high voltage of the external power source into a low voltage (such as converting 220V AC into 5V DC) and provides it to the first voltage converter 122. The first voltage converter 122 then converts the external voltage into a charging voltage suitable for the battery pack 110 and provides it to the battery pack 110 for charging.

[0072] Exemplarily, when the battery pack 110 is in a charging state, the charging voltage converted by the first voltage converter 122 can be adjusted according to different charging stages of the battery pack 110. Taking the charging stages of the battery pack 110 including dead battery charging, trickle charging, constant current charging, and constant voltage charging as an example, the first voltage converter 122 can convert and provide corresponding charging voltages for different charging stages.

[0073] In some embodiments, the first voltage regulator 121 is LDO1, which is used to power the control part. In the embodiments of the present application, the control part in the phototherapy mask product is implemented by a single-chip microcomputer (Microcontroller Unit, MCU). Based on the power supply requirements of the single-chip microcomputer, the first voltage regulator 121 can convert the battery voltage of the battery pack 110 or the voltage converted by the first voltage converter 122 into a 3.3V power supply voltage, which is provided to the single-chip microcomputer for use.

[0074] In an exemplary embodiment, Figure 4 As shown, the second power supply module 130 includes a second voltage regulator 131, which is used to perform secondary conversion on the voltage converted by the first voltage converter 122 to provide partial power supply to the load when the battery pack 110 is in a discharging state.

[0075] Specifically, the second voltage regulator 131 is LDO2, which is used to power the load part. Taking the power supply of the infrared sensor as an example, its voltage requirement is 1.8V, and then the second voltage regulator 131 can perform a secondary conversion on the voltage (11V) converted by the first voltage converter 122 to obtain a 1.8V power supply voltage, which is provided to the infrared sensor. In addition, in the case where the load part includes devices with multiple power supply requirements, the second power supply module 130 may include multiple voltage stabilizing devices, and the voltages corresponding to the conversions obtained with the multiple power supply requirements are provided to each device.

[0076] It can be understood that when the load part and other parts of the product are set independently of each other, that is, when the load part is implemented in the form of a mask and the other parts are implemented in the form of a remote control, the mask side and the remote control side can be provided with their corresponding controllers to realize overall control. Figure 2 , MCU1 is the controller on the remote control side, and MCU2 is the controller on the mask side.

[0077] Correspondingly, in an exemplary embodiment, continue to refer to Figure 2 The second power supply module 130 includes a second voltage regulator 131 and a third voltage regulator 132; when the battery pack 110 is in a discharging state, the second voltage regulator 131 is used to receive the voltage converted by the first voltage converter 122 through an interface, and provide power to the load part after secondary conversion; when the battery pack 110 is in a discharging state, the third voltage regulator 132 is used to receive the voltage converted by the first voltage converter 122 through an interface, and provide power to the mask side control part after secondary conversion.

[0078] Specifically, the second voltage regulator 131 is LDO2, and the third voltage regulator 132 is LDO3. The voltage converted by the first voltage converter 122 can be transmitted to the second voltage regulator 131 and the third voltage regulator 132 through an interface.

[0079] It can be understood that the second voltage regulator 131 is used to provide power to the load part, and the specific voltage conversion application example can refer to the description of the previous embodiment. Similarly, the third voltage regulator 132 is used to provide power to the mask side control part, and the mask side control part can also be implemented by a single chip microcomputer (MCU). The specific voltage conversion application example can refer to the above description and will not be repeated here.

[0080] In an exemplary embodiment, referring to Figure 2 and Figure 3 The third power supply module 140 includes a second voltage converter 141 and a first switch 142; when the battery pack 110 is in a discharging state, the second voltage converter 141 is used to provide power to the auxiliary part with the voltage converted by the first voltage converter 122; when the battery pack 110 is in a charging state, the external voltage of the external power supply is used to power the auxiliary part through the first switch 142.

[0081] Specifically, the second voltage converter 141 is DCDC2, and the first switch 142 is MOS1. The input ends of the second voltage converter 141 and the first switch 142 are both connected to the line from the first voltage converter 122 to the interface. The output ends of the second voltage converter 141 and the first switch 142 are both connected to the devices of the auxiliary part. It can be understood that when the first switch 142 is turned on, the devices of the auxiliary part are directly connected to the line from the first voltage converter 122 to the interface; and when the first switch 142 is turned off, the devices of the auxiliary part are connected to the line from the first voltage converter 122 to the interface through the second voltage converter 141. It can be further understood that the first switch 142 is used to control whether it is necessary to perform secondary voltage conversion through the second voltage converter 141 before powering the devices of the auxiliary part.

[0082] In fact, the auxiliary components may include communication components and interactive components, etc. Based on the power supply requirements of these components, taking the 5V power supply voltage of the Bluetooth communication component as an example, when the battery pack 110 is in a charging state and the external voltage obtained by the interface is also 5V, the first switch 142 can be turned on and the second voltage converter 141 can be controlled to stop working, so that the Bluetooth communication component is directly powered by the external voltage obtained by the interface. When the battery pack 110 is in a discharging state, the first switch 142 can be turned off, and the voltage converted by the first voltage converter 122 is converted twice by the second voltage converter 141 to a 5V power supply voltage for the Bluetooth communication component.

[0083] In an exemplary embodiment, referring to Figure 2 and Figure 3The power supply device further includes a second switch 150 , the first power supply module 120 is connected to the interface via the second switch 150 , and the third power supply module 140 is connected to the interface via the second switch 150 .

[0084] Specifically, the second switch 150 is MOS2, which can be used to cut off the power supply, that is, when the battery pack 110 is in a discharging state, the power supply to the mask side is cut off; when the battery pack 110 is in a charging state, the charging to the remote control side is cut off.

[0085] In an exemplary embodiment, a mask device is provided, comprising the power supply device as described above. It can be understood that the power supply device is used to provide power for the mask device.

[0086] In an exemplary embodiment, the mask device also includes a remote control device and a phototherapy mask device that can be connected through an interface, the battery pack, the first power supply module and the third power supply module are arranged in the remote control device, and the second power supply module is arranged in the phototherapy mask device.

[0087] Specifically, the phototherapy mask device is provided with a load part device that provides a phototherapy care function, which can be set independently from other parts, that is, the remote control device is set separately from the phototherapy mask device, and the two are detachably connected through an interface. The phototherapy mask device may include a phototherapy lamp, a phototherapy lamp driver, an infrared sensor, and a mask side controller. The remote control device may include a communication component, an interactive component, and a remote controller side controller.

[0088] It can be understood that the implementation solution provided by the mask device to solve the problem is similar to the implementation solution recorded in the above-mentioned power supply device. Therefore, the specific limitations in one or more mask device embodiments provided above can refer to the limitations on the power supply device above, and will not be repeated here.

[0089] In combination with the above embodiments, in an exemplary embodiment, Figure 5 As shown, a control method for a power supply device is provided, which is used to control the power supply device of any of the above embodiments, and can be specifically applied to the controller of the above power supply device. The method includes steps 202 to 208, wherein:

[0090] Step 202: After the battery pack enters the discharge state, the third power supply module, the first power supply module and the second power supply module are controlled in sequence to start supplying power.

[0091] It can be understood that when the interface of the remote control device is connected to the phototherapy mask device, the controller on the remote control side can control the battery pack to enter a discharge state.

[0092] Specifically, after the battery pack enters the discharge state, the power-on process of the phototherapy mask device needs to control the third power supply module, the first power supply module and the second power supply module to start power supply in sequence to ensure stable power supply of the phototherapy mask product. That is, the third power supply module is enabled first, and then the first power supply module is enabled to convert the battery voltage of the battery pack to provide overall power supply, and finally the second power supply module is controlled to start and provide power to the load part.

[0093] Step 204: After the battery pack exits the discharge state, the second power supply module, the first power supply module and the third power supply module are controlled to be powered off in sequence.

[0094] It can be understood that when the interface of the remote control device does not detect the connection of the phototherapy mask device, or the mask side controller drives the phototherapy lamp to turn off in response to user operation, or responds to a timed shutdown task, the remote control side controller can control the battery pack to exit the discharge state.

[0095] Specifically, after the battery pack exits the discharge state, during the power-off process of the phototherapy mask device, the remote controller can first control the second switch to disconnect to disconnect the power supply to the phototherapy mask device. Then control the second power supply module, the first power supply module and the third power supply module to disconnect in turn to ensure that there are no problems of false detection, false control and repeated power startup during the power-off process. That is, the second power supply module is disconnected first, and when it is confirmed that the mask side controller has completed the shutdown, the first power supply module is controlled to disconnect, and finally, after the devices in the auxiliary part have exhausted the power stored in the equipment circuit, the third power supply module is disconnected to achieve overall power off.

[0096] Step 206: After the battery pack enters the charging state, the third power supply module and the first power supply module are controlled in sequence to start charging.

[0097] It can be understood that when the interface of the remote control device is connected to the adapter, the controller on the remote control side can control the battery pack to enter a charging state.

[0098] Specifically, after the battery pack enters the charging state, the charging and power-on process of the battery pack needs to control the third power supply module and the first power supply module in sequence to start charging. That is, the third power supply module is enabled first, and then the first power supply module is enabled, and the battery pack is charged through the external voltage of the external power supply, and the auxiliary part is powered.

[0099] In the process of charging the battery pack, if the battery pack is fully charged and the interface of the remote control device is still connected to an adapter, the first power supply module needs to be controlled to stop charging the battery pack, and the battery pack needs to be controlled to enter a repeated charging state. In the repeated charging state, the remote controller can continuously detect the power level of the battery pack, and when the voltage of the battery pack is consumed to a set threshold, the first power supply module is controlled to start charging.

[0100] Step 208: After the battery pack exits the charging state, the first power supply module and the third power supply module are controlled in sequence to stop charging.

[0101] It can be understood that when the interface of the remote control device is not connected to an adapter, the remote controller can control the battery pack to exit the charging state.

[0102] Specifically, after the battery pack exits the charging state, the first power supply module and the third power supply module need to be controlled to stop charging in sequence during the charging and power-off process of the battery pack. That is, the first power supply module is enabled first, and after the auxiliary part of the device exhausts the power stored in the device circuit, the third power supply module is disconnected to achieve overall power off.

[0103] It can be understood that the execution of step 202 and step 204 can be in a sequential relationship, and the execution of step 206 and step 208 can be in a sequential relationship, but there is no strict order restriction between the execution of step 202 and step 204 and the execution of step 206 and step 208.

[0104] In an exemplary embodiment, Figure 6 As shown, step 202 includes steps 302 to 306, wherein:

[0105] Step 302: After the battery pack enters the discharge state, the first switch is controlled to be disconnected and the second voltage converter is controlled to start supplying power.

[0106] Specifically, when the interface of the remote control device is connected to the light therapy mask device, the remote controller can control the battery pack to enter a discharge state. After the battery pack enters the discharge state, the first switch can be controlled to disconnect and an enable signal can be sent to control the second voltage converter to start, that is, the auxiliary part components are powered after the secondary voltage conversion is performed by the second voltage converter.

[0107] Step 304: Control the first voltage converter to start power supply. Further, the remote controller communicates with the first voltage converter to control it to convert the battery voltage to provide overall power supply.

[0108] Step 306: Control the second switch to be turned on, and control the second regulator and the third regulator to start supplying power.

[0109] Finally, the second switch is turned on to provide the voltage converted by the first voltage converter to the phototherapy mask device for power supply. Specifically, the second voltage regulator can perform a secondary conversion on the voltage converted by the first voltage converter and provide power to the load part, and the third voltage regulator can perform a secondary conversion on the voltage converted by the first voltage converter and provide power to the mask side controller. In addition, after the second switch is turned on, the voltage converted by the first voltage converter is also directly provided to the phototherapy lamp for power supply.

[0110] In an exemplary embodiment, Figure 7 As shown, step 204 includes steps 402 to 406, wherein:

[0111] Step 402: After the battery pack exits the discharge state, the second switch is controlled to be disconnected.

[0112] Specifically, when the interface of the remote control device does not detect the connection of the phototherapy mask device, or the mask side controller drives the phototherapy lamp to turn off in response to the user operation, or responds to the timed shutdown task, the remote control side controller can control the battery pack to exit the discharge state. After the battery pack exits the discharge state, it is necessary to first control the second switch to disconnect the power supply to the phototherapy mask device.

[0113] Step 404: After the communication signal fed back by the mask-side control part is not detected, the first voltage converter is controlled to be powered off.

[0114] Furthermore, after the mask side controller is powered off and shut down, the communication signal fed back by the mask side control part cannot be detected, and the first voltage converter can be controlled to be powered off to stop providing overall power supply.

[0115] Step 406: After the auxiliary part exhausts the power of the second voltage converter, the second voltage converter is controlled to be powered off. Finally, after the components of the auxiliary part exhaust the power stored in the device loop, the second voltage converter is disconnected to achieve overall power off.

[0116] In an exemplary embodiment, Figure 8 As shown, step 206 includes steps 502 to 506, wherein:

[0117] Step 502: After the battery pack enters the charging state, the second switch is controlled to be turned on.

[0118] Specifically, when the interface of the remote control device is connected to the adapter, the remote controller can control the battery pack to enter the charging state. After the battery pack enters the charging state, the second switch can be controlled to conduct first to access the charging voltage input by the adapter through the interface.

[0119] Step 504: Control the first switch to be turned on and the second voltage converter to be powered off. Further, the first switch is turned on so that the auxiliary device is directly powered by the external voltage obtained through the interface, and the second voltage converter is controlled to be powered off.

[0120] Step 506: After detecting that the system is operating normally, control the first voltage converter to start charging the battery pack. Finally, the remote controller can communicate with the first voltage converter, and after detecting that the system is operating normally, control the first voltage converter to start charging the battery pack.

[0121] In an exemplary embodiment, Fig. 9 As shown, step 208 includes steps 602 to 604, wherein:

[0122] Step 602: After the battery pack exits the charging state, the first voltage converter stops charging and feeds back charging stop information.

[0123] Specifically, when the interface of the remote control device is not connected to an adapter, the remote controller can control the battery pack to exit the charging state. After the battery pack exits the charging state, the first voltage converter needs to stop the charging process of the battery pack and feed back charging stop information to the remote controller to inform the remote controller that charging has stopped.

[0124] Step 604: After the auxiliary part exhausts the circuit power, the first switch is controlled to be disconnected. After the remote controller receives the charging stop information and the auxiliary part device exhausts the power stored in the device circuit, the second voltage converter is disconnected to achieve overall power off.

[0125] In a specific embodiment, a control method for a power supply device is provided to Figure 2 and Figure 3 The mask device shown is powered.

[0126] The following first Figure 2 and Figure 3 The devices in the figure are explained as follows: DCDC1: performs boost and buck functions, controlled by MCU1, and bucks the adapter voltage to provide battery charging during charging, and boosts the battery voltage to 11V to provide mask operation during discharging; LDO1: stabilizes the battery voltage to 3.3V and provides it to MCU1 for operation; MOS1: adjusts the power supply path of Bluetooth and display; MOS2: cuts off the power; DCDC2: when discharging, it bucks the 11V boosted by DCDC1 to 5V to provide power for Bluetooth and display; TYPE interface: when discharging, it docks with the mask to provide power; when charging, it docks with the adapter to receive power; MCU1: the main control chip on the remote control side, which communicates with the mask main control during discharging; Phototherapy lamp: an LED lamp used for phototherapy care; LDO2: stabilizes 1.8V to provide power for infrared sensing; LDO3: stabilizes 3.3V to provide power for MCU2; MCU2: the main control chip on the mask side, which handles infrared sensing and controls the phototherapy lamp; EN: enable control of DCDC2.

[0127] The working principle of the above-mentioned mask equipment is introduced as follows:

[0128] When charging: the adapter is connected to the TYPE interface to provide 5V power to the remote control. At this time, MCU1 turns on MOS2, so that the adapter power 5V_2 enters DCDC1. MCU1 communicates with DCDC1 through IIC, so that DCDC1 steps down the voltage to provide battery charging; LDO1 converts the battery voltage to 3.3V and provides power for MCU1; at this time, MCU1 turns off the EN pin, DCDC2 no longer works, and turns on MOS1 at the same time. 5V_2 provides power for Bluetooth and display through MOS1.

[0129] During discharge: the beauty mask is connected to the TYPE interface, LDO1 converts the battery voltage to 3.3V and provides power to MCU1; the battery power 3.7V is provided to DCDC1, MCU1 communicates with DCDC1 through IIC, so that DCDC1 is boosted to 11V, MCU1 turns on MOS2, and 11V_1 is provided to the TYPE interface to provide mask operation; at this time, MCU1 turns on the EN pin, DCDC2 starts working, and turns off MOS1 at the same time, and DCDC2 outputs 5V to provide power for Bluetooth and display.

[0130] Mask part: receives 11V power from the remote control, provides it to the light therapy lamp, and MCU2 provides driving instructions; provides it to LDO2 to convert it into 1.8V, provides it for infrared operation, and MCU2 receives infrared signals; provides it to LDO3 to convert it into 3.3V, and provides it for MCU2 to work.

[0131] The following describes the power-on and power-off process of the battery pack in the charging and discharging states:

[0132] like Fig.10 As shown, when powered on in the charging stage, MCU1 turns on MOS2 first, turns off EN enable, turns off DCDC2, turns on MOS1, provides the adapter power 5V to Bluetooth and display, and then communicates with DCDC1. After the system is detected to be normal, the charging mode is turned on; LDO1 directly converts the battery voltage into 3.3V to provide MCU1 work;

[0133] like Fig.11 As shown, when the power is off, the adapter is unplugged, and the adapter is detected to be unplugged, DCDC1 passively stops charging, and feedback information is sent to MCU1 through IIC. MCU1 keeps MOS1 turned on, and releases the energy stored in the capacitor in the circuit through Bluetooth and display, completing the automatic power off, and then MCU1 enters sleep mode;

[0134] In special cases, when the battery is fully charged, DCDC1 stops charging the battery, detects the battery condition, and enters the repeated charging mode. When the battery power is naturally depleted to the set value, charging is started again. At this time, MCU1 keeps MOS2 turned on, turns off EN, turns off DCDC2, turns on MOS1, and provides the adapter power 5V to Bluetooth and display.

[0135] like Fig.12 As shown, when the mask is working, MCU1 detects that the mask is inserted, MCU1 turns off MOS1, turns on EN, enables DCDC2, MCU1 communicates with DCDC1 through IIC, the battery voltage is boosted to 11V through DCDC1, MCU1 turns on MOS2, 11V is 11V_1 through MOS1, and is provided to the TYPE interface to provide mask operation; at this time, DCDC2 converts 11V to 5V to provide Bluetooth and display operation; the mask receives the 11V power supply provided by the remote control, which is provided to the phototherapy lamp for operation, and the driving instructions are provided by MCU2; it is provided to LDO2 for conversion to 1.8V, for infrared operation, and MCU2 receives infrared signals; it is provided to LDO3 for conversion to 3.3V, for MCU2 to work;

[0136] like Fig.13 As shown, when the system is shut down actively (including manual shutdown and timed shutdown), MCU2 drives the light therapy lamp to turn off, and MCU1 turns off MOS2. At this time, MCU1 sends a communication command. If communication is not possible, MCU2 has completed the shutdown. If communication is possible, it will wait for MCU2 to power off before communicating. After confirming that MCU2 has completed power off, MCU1 turns off DCDC1 through IIC, keeps MOS1 off, and enables DCDC2 to continue working to provide power for Bluetooth and display, until the system storage power is exhausted and the system automatically powers off, and then MCU1 enters sleep mode.

[0137] In special circumstances, when the mask is working, if the mask part can continue to work, then when the communication is disconnected, MCU2 drives the phototherapy lamp to turn off. If not, the infrared and MCU2 consume power by themselves to complete the power-off. On the remote control, after the communication is disconnected, MCU1 turns off DCDC1 through IIC, keeps MOS1 off, and enables DCDC2 to continue working to provide power for Bluetooth and display until the system storage power is exhausted and the power is automatically turned off, and then MCU1 enters sleep mode.
