Referring to fig. 1 and fig. 2 together, the control circuit 20 includes a light emitting module 21 and a controller 22.

The light emitting module 21 is used for emitting light. In one embodiment, the light module 21 includes a lamp. Wherein, the lamp tube can be an IPL lamp tube, and the light emitted by the IPL lamp tube can be emitted to the skin of a user. The color of the light emitted by the lamp tube is not limited, and can be color light, composite light, and the like, and the specific wavelength and frequency of the lamp tube are determined according to the use condition.

The controller 22 is connected to the light emitting module 21, and the controller 22 is configured to control the light emitting duration of the light emitting module 21 and/or the light emitting power, that is, the controller 22 can control at least one of the light emitting duration and the light emitting power of the light emitting module 21.

The controller 22 may be a Micro Controller Unit (MCU) or a Digital Signal Processing (DSP) controller.

The controller 22 includes at least one processor 221 and a memory 222, wherein the memory 222 may be built in the controller 22 or external to the controller 22, and the memory 222 may also be a remotely disposed memory connected to the controller 22 through a network.

The memory 222 may include a storage program area and a storage data area, wherein the storage program area may store an operating system, an application program required for at least one function; the storage data area may store data created according to the use of the terminal, and the like. Further, the memory 222 may include high speed random access memory, and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other non-volatile solid state storage device. In some embodiments, the memory 222 may optionally include memory located remotely from the processor 221, which may be connected to the terminal through a network. Examples of such networks include, but are not limited to, the internet, intranets, local area networks, mobile communication networks, and combinations thereof.

The beauty treatment apparatus 1000 may include apparatuses for beautifying or improving a human body, such as a depilator and a beauty treatment apparatus.

Meanwhile, the hardware structure of the beauty treatment apparatus 1000 as shown in fig. 2 is only one example, and the beauty treatment apparatus 1000 may have more or less components than those shown in the drawing, may combine two or more components, or may have a different component configuration, and various components shown in the drawing may be implemented in hardware, software, or a combination of hardware and software including one or more signal processing and/or application specific integrated circuits.

For example, in one embodiment, as shown in fig. 3, the cosmetic device 1000 further includes a power control module 23.

The power control module 23 is connected to the controller 22 and the light emitting module 21, respectively. The power control module 23 is used for controlling the light emitting power of the light emitting module 21 in response to the first signal output by the controller 22.

In one embodiment, as shown in fig. 4, the power control module 23 includes a driving unit 231 and an energy storage unit 232. The driving unit 231 is connected to the controller 22, and the energy storage unit 232 is connected to the driving unit 231.

Specifically, the driving unit 231 outputs a driving signal in response to the first signal. The energy storage unit 232 is configured to charge in response to the driving signal and discharge the light emitting module 21 based on the voltage of the energy storage unit 232, so that the light emitting module 21 emits light. And the light emitting power of the light emitting module 21 and the voltage of the energy storage unit 232 show a positive correlation. Meanwhile, to ensure safety, the voltage of the energy storage unit 232 needs to be limited within a safe voltage range that the light emitting module 21 can bear. For example, if the light emitting module 21 is an IPL lamp, the safe voltage may be 300V-600V.

Take the example of charging the voltage of the energy storage unit 232 to 400V. First, when the controller 22 determines that the voltage of the energy storage unit 232 is less than 400V, the controller 22 outputs a first signal to the driving unit 231, and the driving module 200 drives the energy storage unit 232 to charge. When the voltage of the energy storage unit 232 rises to 400V, the controller 22 stops outputting the first signal to the driving unit 231, and the driving unit 231 turns off the driving. Then, the lamp tube of the IPL may be discharged by the 400V high voltage of the energy storage unit 232, so that the IPL may emit strong pulse light. Meanwhile, the voltage of the energy storage unit 232 is gradually reduced along with the discharging process, so that the system voltage is always within a safety range.

Fig. 4 also illustrates a structure of the driving unit 231. As shown in fig. 4, the driving unit 231 includes a PFC (Power Factor Correction) chip U1. The first signal output by the controller 22 includes a first pulse signal and a second pulse signal, the first pulse signal is input to the PN1 terminal of the PFC chip U1, and the second pulse signal is input to the PN2 terminal of the PFC chip U1. The PN3 terminal of the PFC chip U1 outputs a driving signal to the energy storage unit 232.

Fig. 4 also illustrates an example of a structure of the energy storage unit 232. As shown in fig. 4, the energy storage unit 232 includes a first switching tube Q1, a transformer T1 and an electrolytic capacitor Ca connected in sequence. The first switch tube Q1 is connected to the driving unit 231, and the transformer T1 is connected to the first power source V1, the first switch tube Q1 and the electrolytic capacitor Ca. The primary winding of the transformer T1 is connected to a first power source V1, and the secondary winding is connected to the electrolytic capacitor Ca.

Specifically, the first switch tube Q1 is configured to be turned on when the driving signal is not received, so that the first power source V1 stores energy in the primary winding of the transformer T1, and the electrolytic capacitor Ca is discharged. The first switch tube Q1 is also used to open when receiving a driving signal, so that the primary winding of the transformer T1 transfers energy to the secondary winding, and the secondary winding charges the electrolytic capacitor Ca.

In this embodiment, when the PFC chip U1 receives the first pulse signal and has a low level, the PFC chip U1 outputs a driving signal to the first switch tube Q1 through the PN3 terminal. The first switch tube Q1 is turned on upon receiving the driving signal. At this time, the first power source V1 stores energy in the primary winding of the transformer T1, the voltage in the primary winding rises, the secondary winding does not operate, and the voltage of the electrolytic capacitor Ca falls.

When the PFC chip U1 receives the first pulse signal at a high level, the PFC chip U1 stops outputting the driving signal to the first switching tube Q1. The first switch tube Q1 is turned off without receiving the driving signal. The primary winding of the transformer T1 transfers energy to the secondary winding, which charges the electrolytic capacitor Ca. The voltage of the electrolytic capacitor Ca rises until the voltage across it rises to 400V to meet the lighting requirements of the lighting module 21.

And the above control process is repeated to make the first switch tube Q1 periodically turn on and off, and the transformer T1 periodically charges the electrolytic capacitor Ca. It is understood that, in other embodiments, the transformer T1 may also increase the voltage of the electrolytic capacitor Ca to other specified voltage values according to the lighting power requirement of the lighting module 21. The first switch tube Q1 may be any switch element with high voltage resistance, such as a MOS tube and a triode. The energy storage unit 232 is formed by combining the first switch tube Q1, the transformer T1 and the electrolytic capacitor Ca, the control of charging and discharging of the electrolytic capacitor Ca can be realized by controlling the on-off of the first switch tube Q1 through the driving unit 231, and the control mode is simple and the response is sensitive.

Referring back to fig. 3, in an embodiment, the beauty treatment apparatus 1000 further includes a temperature and humidity detection module 24. The temperature and humidity detection module 24 is connected to the controller 22. The temperature and humidity detecting module 24 is used for detecting the temperature and humidity of the surrounding environment where the module is located.

The temperature and humidity detection module 24 may be disposed at any position of the beauty treatment apparatus 1000. The number of the temperature/humidity detection modules 24 may be one or more. When the temperature/humidity detection modules 24 are plural, different temperature/humidity detection modules 24 may be disposed at different positions of the beauty treatment apparatus 1000.

Referring to fig. 1 and fig. 3 together, in an embodiment, the beauty treatment apparatus 1000 further includes a first air outlet 30 and a second air outlet 40. The first air outlet 30 and the second air outlet 40 are both used for providing an air outlet channel when the fan blows air to dissipate heat of elements in the beauty treatment apparatus 1000, so as to exhaust heat. However, when the beauty apparatus 1000 is in a humid environment (such as a humid toilet), humid air may enter the beauty apparatus 1000 through the first air outlet 30 and the second air outlet 40, which may cause an abnormality such as a short circuit of a component (such as the power control module 23) in the control circuit 20, and may even damage the component in the control circuit 20, which may further damage the beauty apparatus 1000. Therefore, the temperature and humidity detection modules 24 may be disposed at the first outlet 30 and the second outlet 40 to detect the humidity of the first outlet 30 and the second outlet 40 in real time. Therefore, when the humidity of the first outlet 30 and the humidity of the second outlet 40 are greater than the preset humidity value of the corresponding position, the operation of each part in the control circuit 20, for example, the operation of the power control module 23, may be stopped in time to protect the control circuit 20. At the same time, the light emitting module 21 is also controlled to stop emitting light. Furthermore, the probability of abnormity of the beauty equipment when the beauty equipment is used in different environments can be reduced, the service life of the beauty equipment is prolonged, and the use safety is improved.

Of course, the temperature and humidity detection module 24 may be disposed at other positions. For example, the temperature/humidity detection module 24 is provided near the electrolytic capacitor of the power control module 23 to achieve more accurate detection.

For another example, a temperature and humidity detecting module 24 is disposed on the upper case 13 shown in fig. 1, and the temperature and humidity detecting module 24 is configured to detect the humidity of the skin surface in contact with the beauty treatment apparatus 1000 when the beauty treatment apparatus 1000 is in contact with the skin of the user. Then, the light emitting power of the light emitting module 21 can be controlled according to the humidity of the skin surface, so as to achieve better beauty effect.

The temperature and humidity detection module 24 can also detect the temperature at the same time. Then, when the temperature is determined to be higher than the preset temperature value of the corresponding position, the heat dissipation effect may be poor or the control circuit 20 may generate heat seriously, and the like, and the control circuit 20 may be damaged, or even the skin of the human body may be damaged due to the overhigh temperature. Therefore, when the temperature is higher than the preset temperature value of the corresponding position, the operation of the control circuit 20 is stopped in time, and the emission of the light by the emitting module 21 is stopped, that is, the power of the emitting module 21 is controlled to be zero correspondingly.

In an embodiment, please continue to refer to fig. 3, the temperature and humidity detecting module 24 includes a temperature and humidity sensor M1. The temperature/humidity sensor M1 is connected to the controller 22. The temperature/humidity sensor M1 is configured to detect a humidity and a temperature, and output a detection signal corresponding to the detected temperature and humidity to the controller 22. The controller 22 may then determine the detected temperature and humidity from the received detection signal.

Take the temperature and humidity detecting module 24 disposed at the first outlet 30 as an example. The temperature and humidity detecting module 24 detects the humidity and temperature of the environment near the first air outlet 30, and generates a corresponding detecting signal to the controller 22 according to the detected result. The controller 22 can determine the humidity and temperature of the environment near the first outlet 30 according to the received detection signal.

In an embodiment, with continued reference to fig. 1 and fig. 3, the cosmetic apparatus 1000 further includes a fan 50, and the control circuit 20 further includes a fan control module 25. The fan control module 25 is connected to the controller 22 and the fan 50, respectively.

Specifically, fan control module 25 is configured to control fan 50 to rotate in response to a second signal output by controller 22. The second signal may be a Pulse Width Modulation (PWM) signal, and a duty ratio of the second signal is related to a rotation speed of the fan 50 when the fan rotates. That is, by adjusting the duty ratio of the second signal, the adjustment of the rotation speed of the fan 50 can be achieved. When it is detected that there is a high humidity or temperature in at least one position of the beauty treatment apparatus 1000, the fan 50 may be controlled to rotate at a rotation speed greater than zero, so as to reduce the humidity and temperature by blowing air through the fan.

Referring to fig. 5, fig. 5 illustrates an exemplary configuration of the fan control module 25. As shown in fig. 5, the fan control module 25 includes a first switch unit 251 and a second switch unit 252. The first switch unit 251 is connected to the controller 22 and the second switch unit 252, and the second switch unit 252 is connected to the second power source V2 and the fan 50.

Specifically, the first switching unit 251 is used to be turned on or off in response to the second signal. The second switching unit 252 is configured to be turned on when the first switching unit 251 is turned on to establish a connection between the second power source V2 and the fan 50. The second switching unit 252 is also used to be turned off when the first switching unit 251 is turned off to disconnect the second power source V2 from the fan 50.

In this embodiment, when the second signal output by the controller 22 is at a high level, the first switch unit 251 is turned on, the second switch unit 252 is also turned on, and the power pin of the fan 50 is connected to the second power supply V2; when the second signal output by the controller 22 is at a low level, the first switch unit 251 is turned off, and the second switch unit 252 is also turned off, so that the connection between the power pin of the fan 50 and the second power supply V2 is disconnected.

As can be seen, the duty ratio of the second signal is the ratio of the on duration of the first switch unit 251 (and the second switch unit 252) in one period to the duration of one period. When the second switching unit 252 is turned on, the fan 50 is connected to the second power supply V2; when the second switching unit 252 is turned off, the connection between the fan 50 and the second power supply V2 is disconnected. Thus, in one cycle, the voltage that powers the fan 50 is the product of the voltage of the second power supply V2 and the duty ratio. By varying the duty cycle of the second signal while the voltage of the second power supply V2 remains constant, the voltage that powers the fan 50 during a cycle, and thus the speed of the fan 50, can be varied.

Fig. 5 also shows a structure of the first switching unit 251. As shown in fig. 5, the first switch unit 251 includes a first resistor R1, a second resistor R2 and a second switch Q2.

The first end of the first resistor R1 is connected to the controller 22, the second end of the first resistor R1 is connected to the first end of the second resistor R2 and the first end of the second switch tube Q2, the second end of the second resistor R2 and the second end of the second switch tube Q2 are both grounded GND, and the third end of the second switch tube Q2 is connected to the second switch unit 252.

Specifically, the first resistor R1 and the second resistor R2 are used for dividing a voltage corresponding to the second signal output by the controller 22, so as to prevent the second switch Q2 from being damaged due to an excessively large voltage input to the first end of the second switch Q2. The first resistor R1 can also function as a current limiting. In addition, when the second signal is at a high level, the second switch tube Q2 is turned on; when the second signal is low, the second switch Q2 is turned off. The second switch tube Q2 is turned on and corresponds to the first switch unit 251; the second switch Q2 is turned off corresponding to the first switch unit 251 being turned off.

In this embodiment, the second switching transistor Q2 is an NPN transistor, for example. The base electrode of the NPN type triode is the first end of the second switch tube Q2, the emitter electrode of the NPN type triode is the second end of the second switch tube Q2, and the collector electrode of the NPN type triode is the third end of the second switch tube Q2.

In addition, the second switch Q2 may be any controllable switch, such as an Insulated Gate Bipolar Transistor (IGBT) device, an Integrated Gate Commutated Thyristor (IGCT) device, a gate turn-off thyristor (GTO) device, a Silicon Controlled Rectifier (SCR) device, a junction gate field effect transistor (JFET) device, a MOS Controlled Thyristor (MCT) device, and so on. In addition, the second switching tube Q2 shown in fig. 5 may be implemented as a plurality of switches connected in parallel.

One configuration of the second switching unit 252 is also shown in fig. 5. As shown in fig. 5, the second switch unit 252 includes a third resistor R3, a fourth resistor R4 and a third switch Q3.

A first end of the third resistor R3 is connected to the first switch unit 251, a second end of the third resistor R3 is connected to a first end of the fourth resistor R4 and a first end of the third switching tube Q3, a second end of the third switching tube Q3 is connected to a second end of the fourth resistor R4 and the second power supply V2, and a third end of the third switching tube Q3 is connected to a power supply pin (i.e., pin 1) of the fan 50.

Specifically, the third resistor R3 and the fourth resistor R4 are used for dividing the voltage of the second power source V2 to prevent the voltage input to the first end of the third switching tube Q3 from being too large to damage the third switching tube Q3.

In this embodiment, when the second switch Q2 is turned on, the first end of the third resistor R3 is grounded GND. The second power supply V3, the third resistor R3 and the fourth resistor R4 form a loop, and the third resistor R3 and the fourth resistor R4 divide the voltage of the second power supply V2 to provide a conducting voltage drop for the third switching tube Q3, so that the third switching tube Q3 is conducted. The third switch Q3 is turned on corresponding to the second switch unit 252.

When the second switch tube Q2 is turned off, the loop in which the third resistor R3 and the fourth resistor R4 are located is disconnected. The third switch Q3 loses conduction voltage drop, and the third switch Q3 is turned off. Wherein, the turn-off of the third switching tube Q3 corresponds to the turn-off of the second switching unit 252.

In this embodiment, the third switching transistor Q3 is taken as a PMOS transistor as an example. The grid electrode of the PMOS tube is the first end of the second switch tube Q2, the source electrode of the PMOS tube is the second end of the second switch tube Q2, and the drain electrode of the PMOS tube is the third end of the second switch tube Q2.

In addition, the third switch Q3 may be any controllable switch, such as an Insulated Gate Bipolar Transistor (IGBT) device, an Integrated Gate Commutated Thyristor (IGCT) device, a gate turn-off thyristor (GTO) device, a Silicon Controlled Rectifier (SCR) device, a junction gate field effect transistor (JFET) device, a MOS Controlled Thyristor (MCT) device, and the like. In addition, the third switching tube Q3 shown in fig. 5 may be implemented as a plurality of switches connected in parallel.

In an embodiment, referring to fig. 5, the fan control module 25 further includes a feedback unit 253, a voltage stabilizing unit 254, and a freewheeling unit 255. The feedback unit 253 is connected to the fan 50 and the controller 22, the voltage-stabilizing unit 254 is connected to the second power source V2, and the freewheeling unit 255 is connected to the fan 50.

Specifically, the feedback unit 253 is configured to output a feedback signal corresponding to the rotation speed of the fan 50 to the controller 22, so that the controller 22 determines the actual rotation speed of the fan 50 according to the feedback signal. The voltage stabilizing unit 254 is configured to be broken down and stabilized when the voltage of the second power source V2 is greater than the first preset voltage, so as to prevent the third switching tube Q3 from being damaged due to an excessive input voltage when the voltage of the second power source V2 fluctuates. The free-wheeling unit 255 is used to free-wheel when the fan 50 stops rotating, and since an inductive load exists in the fan 50, an abrupt voltage is generated when it stops rotating, which may damage other components. Therefore, by matching the flywheel unit 255, the current can be changed more smoothly, and the occurrence of a surge voltage can be avoided.

Fig. 5 also shows a structure of the feedback unit 253. As shown in fig. 5, the feedback unit 253 includes a fifth resistor R5 and a sixth resistor R6.

A first end of the fifth resistor R5 is connected to the third power supply V3, a second end of the fifth resistor R5 is connected to a first end of the sixth resistor R6 and a signal feedback pin (i.e., pin 2) of the fan 50, respectively, and a second end of the sixth resistor R6 is connected to the controller.

By providing the third power supply V3, the signal output from the 2 nd pin of the fan 50 can be converted into a signal that can be recognized by the controller 22, so that the controller 22 can determine the actual rotation speed of the fan 50 in real time.

Fig. 5 also shows a structure of the feedback unit 253. As shown in fig. 5, the voltage stabilizing unit 254 includes a voltage stabilizing diode DW1 and a first diode D1.

The cathode of the zener diode DW1 is connected to the second power source V2, the anode of the zener diode DW1 is connected to the anode of the first diode D1, and the cathode of the first diode D1 is grounded GND.

Specifically, when the reverse voltage of the zener diode DW1 approaches a critical value of the reverse voltage, the reverse current abruptly increases, i.e., the zener diode DW1 is broken down. At this critical breakdown point, the reverse resistance of zener diode DW1 abruptly drops to a very small value. At this time, although the current varies in a wide range, the voltage across the zener diode DW1 is substantially stabilized around the breakdown voltage, thereby implementing the voltage stabilization function of the zener diode DW 1. The first diode D1 can stabilize the voltage, wherein the sum of the forward conducting voltage of the first diode D1 and the breakdown voltage of the zener diode DW1 is the first predetermined voltage in the above embodiment. When the voltage of the second power source V2 is greater than the first preset voltage, the voltage stabilizing diode DW1 is broken down, and at this time, the voltage of the third terminal of the third switching tube Q3 is stabilized at the first preset voltage.

Also shown in fig. 5 is a structure of the freewheel unit 255. As shown in fig. 5, the freewheel unit 255 includes a second diode D2.

An anode of the second diode D2 is connected to a ground pin (i.e., pin 3) of the fan 50, and a cathode of the second diode D2 is connected to a power pin (i.e., pin 1) of the fan 50.

Referring back to fig. 3, in an embodiment, the control circuit 20 further includes a key module 26 and a touch module 27. Wherein the contact module 26 is connected to the controller 22. The key module 27 is connected to the controller 22.

Specifically, the contact module 26 is configured to form a sensing capacitance with the contacted skin, collect a capacitance variation signal of the sensing capacitance, and transmit the capacitance variation signal to the controller 22.

In some embodiments, the contact module 26 includes a contact unit electrically connected to a touch chip, and the touch chip is connected to the controller 22. The contact unit is used for forming an induction capacitor with contacted skin. The touch chip is used for collecting a capacitance value change signal of the sensing capacitor and transmitting the capacitance value change signal to the controller 22.

In this embodiment, when the user uses the cosmetic apparatus 1000, if the side of the cosmetic apparatus 1000 emitting light contacts the skin, an inductive capacitance can be formed between the skin and the contact unit. Specifically, since the skin of the human body has a certain charge, when the face of the beauty treatment apparatus 1000 emitting light contacts the skin, a capacitance substrate can be formed on the skin, and the contact unit is equivalent to another substrate, thereby forming an induction capacitance.

Furthermore, the touch chip can detect the capacitance value change of the induction capacitor because the contact unit is connected with the touch chip. Moreover, because the skin of the human body has a certain charge, the capacitance value change generated when the face of the beauty apparatus 1000 emitting the light contacts the skin of the human body is different from the capacitance value change generated when the face of the beauty apparatus 1000 emitting the light contacts other positions, such as clothes, a table surface and the like, wherein the capacitance value change generated when the face of the beauty apparatus 1000 emitting the light contacts the skin of the human body is more obvious. Therefore, the touch chip can effectively detect whether the touch chip is in contact with the skin by comparing the capacitance change condition, and when it is determined that the touch chip is in contact with the skin, the touch chip generates a detection result (i.e., a capacitance change signal) to the controller 22.

Then, after acquiring the capacity value change signal, the controller 22 may determine whether the cosmetic apparatus 1000 has contacted the skin. And the light emitting module 21 can be controlled to emit light only when it is determined that the cosmetic apparatus 1000 has contacted the skin.

The key module 27 is used for outputting a lighting signal to the controller 22 when being pressed. In one embodiment, one end of the key module 27 is connected to the fourth power source, and the other end is connected to the controller 22, so as to input the lighting signal to the controller 22. Specifically, when the key module 27 is pressed, a connection between the fourth power supply and the controller 22 is established, and the controller 22 receives a high level signal (i.e., a light signal); when the key module 27 is released, the connection between the fourth power supply and the controller 22 is disconnected, and the controller 22 receives a low level signal. Accordingly, if the controller 22 receives the high level signal, it determines that the lighting is required, that is, the controller controls the light emitting module 21 to emit light.

In summary, when the power control module 23 keeps working normally, the light emitting module 21 is controlled to emit light only when it is determined that the beauty treatment apparatus 1000 has contacted the skin and receives the light emitting signal.

Referring to fig. 6, fig. 6 is a flowchart of a control method based on a cosmetic device according to an embodiment of the present application. The beauty equipment comprises a light emitting module for emitting light and a power control module for controlling the light emitting power of the light emitting module. The structure of the depilation instrument can be referred to the above detailed description with respect to figures 1 to 5, and will not be described here in detail. As shown in fig. 6, the control method based on the beauty equipment includes the steps of:

step 601: humidity and temperature of at least one location within the cosmetic device are obtained.

Step 602: and if the humidity of at least one position is greater than the preset humidity value of the corresponding position and/or the temperature of at least one position is greater than the preset temperature value of the corresponding position, controlling the power control module to stop running and controlling the light emitting module to stop emitting light.

In one embodiment, if the beauty equipment includes the first outlet 30 and the second outlet 40 as shown in fig. 1, at least one of the positions may include the first outlet 30 and the second outlet 40. Because the water drops in the environment may enter the beauty equipment through the first air outlet 30 and the second air outlet 40, the humidity of the water drops is detected at the first air outlet 30 and the second air outlet 40, which is beneficial to finding out whether the humidity is abnormal as soon as possible.

Of course, at least one position may also include other positions in the beauty treatment apparatus, such as the control circuit 20 and the like as described in fig. 1, which have been described in detail in the above embodiments and are not described again here.

Then, in an embodiment, when at least one of the locations includes the first outlet port 30 and the second outlet port 40, if the humidity of the at least one location is greater than the preset humidity value of the corresponding location and/or the temperature of the at least one location is greater than the preset temperature value of the corresponding location in step 602, the process of controlling the power control module to stop operating includes the following steps: if the humidity of the first air outlet is greater than a first preset humidity value (corresponding to the preset humidity value of the first air outlet), and/or the temperature of the first air outlet is greater than a first preset temperature value (corresponding to the preset temperature value of the first air outlet), controlling the power control module to stop operating; and if the humidity of the second air outlet is greater than a second preset humidity value (corresponding to the preset humidity value of the second air outlet), and/or the temperature of the second air outlet is greater than a second preset temperature value (corresponding to the preset temperature value of the second air outlet), controlling the power control module to stop running.

The first preset humidity value, the first preset temperature value, the second preset humidity value and the second preset temperature value can be set according to practical application conditions, and the embodiment of the application is not particularly limited. The first preset humidity value and the second preset humidity value can be the same or different; the first preset temperature value and the second preset temperature value may be the same or different, and this is not specifically limited in this embodiment of the application.

In one embodiment, as shown in fig. 7, after the control power control module stops operating in step 602, the control method further includes the following steps:

step 701: and controlling the fan control module to operate so as to control the fan to rotate.

Specifically, after the operation of the power control module is stopped, the fan can be controlled to operate through the fan control module, so that the high-humidity place can be dried, and the high-temperature can be cooled. Therefore, the environment of the power control module can be recovered to a normal working state, namely the detected humidity is smaller than the preset humidity value of the corresponding position, and the detected temperature is smaller than the preset temperature value of the corresponding position, so that the power control module can be conveniently reused by a user.

In one embodiment, the control method further comprises the steps of: when the light-emitting module stops emitting rays, if the humidity of at least one position is larger than the preset humidity value of the corresponding position and/or the temperature of at least one position is larger than the preset temperature value of the corresponding position, the fan control module is controlled to operate to control the fan to rotate.

Specifically, after the cosmetic device is used each time, namely after the light emitting module stops emitting light, the fan can be controlled to rotate, so that the places with higher humidity can be dried, and the temperature with higher temperature can be reduced. And the preset humidity value and the preset temperature value can be correspondingly adjusted to be smaller values at the moment so as to keep the drying and lower temperature of the beauty equipment and be beneficial to prolonging the service life of the beauty equipment.

In an embodiment, as shown in fig. 8, the process of controlling the rotation of the fan in the above steps may include the steps of:

step 801: and determining the target rotating speed of the fan according to the corresponding relation between the humidity and the temperature of at least one position and the preset rotating speed of the fan.

Step 802: the fan rotation is controlled at the target rotation speed.

In one embodiment, the step 801 of determining the target rotation speed of the fan according to the correspondence relationship between the humidity, the temperature and the preset fan rotation speed of at least one location includes the following steps: a humidity interval in which the humidity of the at least one location is located is determined, and a temperature interval in which the temperature of the at least one location is located is determined. And determining the target rotating speed according to the humidity interval, the temperature interval and the corresponding relation between the preset humidity interval and temperature interval and the rotating speed of the fan.

Specifically, at least one humidity interval and at least one temperature interval can be preset, each humidity interval corresponds to one temperature interval and one rotating speed, and the corresponding relationship is the corresponding relationship among the preset humidity interval, the preset temperature interval and the rotating speed of the fan. Then, after the humidity and the temperature of at least one position are obtained, the humidity interval where the detected humidity is located and the humidity interval where the detected temperature is located can be found, and the rotating speed of the fan can be determined.

Table 1 shows the correspondence between the preset humidity range and temperature range and the fan rotation speed.

TABLE 1

First humidity interval a1	First temperature interval b1	First speed of rotation
			First humidity interval a1	Second temperature interval b2	Second rotational speed
Second humidity interval a2	First temperature interval b1	Third rotation speed
			Second humidity interval a2	Second temperature interval b2	Fourth rotational speed
Third humidity interval a3	First temperature interval b1	Fifth rotation speed
			Third humidity interval a3	Second temperature interval b2	Sixth rotation speed

As shown in table 1, in this embodiment, three humidity zones and two temperature zones are taken as an example for description. The three humidity types include a first humidity range a1, a second humidity range a2, and a third humidity range a3. The two temperature ranges include a first temperature range b1 and a second temperature range b2.

Because three humidity intervals and two temperature intervals are included, 6 rotating speeds (including the first rotating speed to the sixth rotating speed) can be corresponded in total, and the magnitude of any two rotating speeds in the 6 rotating speeds can be the same or different. Then, after finding out the corresponding humidity interval and temperature interval according to the detected humidity and temperature, the rotating speed of the fan can be directly determined. For example, if the humidity zone in which the detected humidity is located is the first humidity zone a1 and the temperature zone in which the detected temperature is located is the second temperature zone b2, the rotation speed of the fan is controlled to be the second rotation speed. The control of the rotation speed of the fan may be implemented by controlling a duty ratio of a second signal input by the fan control circuit, and a specific implementation process is described in the above embodiments and is not described herein again.

It should be noted that, in this embodiment, only the way of including three humidity intervals and two temperature intervals is exemplarily shown, and in other embodiments, other division ways may also be adopted. For example, more than three humidity intervals and more than two temperature intervals may be preset to divide more rotation speeds for improving the precision. In addition, in other embodiments, the rotation speed of the fan may also be adjusted in other manners, for example, a manner of setting an option for a user to manually select may also be adopted, which is not specifically limited in the embodiment of the present application.

In one embodiment, the control method further comprises the steps of: and if the humidity of at least one position is not greater than the preset humidity value of the corresponding position and the temperature of at least one position is not greater than the preset temperature value of the corresponding position, controlling the power control module to operate.

When the detected humidity is less than or equal to the corresponding preset humidity value and the detected temperature is less than or equal to the corresponding preset temperature value, the power control module is controlled to operate, and the operation reliability of the power control module can be improved.

Then, after controlling the power control module to operate, the control method further includes the steps of: humidity and temperature of the skin surface in contact with the cosmetic device are obtained. And if the humidity of the skin surface in contact with the beauty equipment is greater than the corresponding preset humidity value and/or the temperature of the skin surface in contact with the beauty equipment is greater than the corresponding preset temperature value, controlling at least one of the luminous power and the luminous duration of the luminous module according to the humidity and the temperature of the skin surface in contact with the beauty equipment.

As can be seen from the above embodiments, by disposing the temperature and humidity detection module 24 on the top case 13, when the cosmetic apparatus is in contact with the skin of the user, the humidity and temperature of the surface of the skin in contact can be obtained. If the humidity of the contacted skin surface is too high, the effect of the beauty equipment on the skin can be influenced; if the temperature of the contacted skin surface is too high, the skin may be burned when the cosmetic device is used. Therefore, at least one of the light emitting power and the light emitting duration of the light emitting module can be controlled according to the humidity and the temperature of the skin surface contacted with the cosmetic device, namely, the light emitting power of the light emitting module, the light emitting duration of the light emitting module or the light emitting power and the light emitting duration of the light emitting module are controlled according to the humidity and the temperature of the skin surface contacted with the cosmetic device. For example, when the humidity of the contacted skin surface is higher, the luminous power can be increased and the luminous time can be prolonged, so as to obtain better cosmetic effect; when the temperature of the contacted skin surface is high, the light emitting power can be reduced and the light emitting time period can be shortened to prevent damage to the skin of the user.

In an embodiment, after controlling the operation of the power control module, the method may further include the steps of: and if the energy storage unit in the power control module is charged to the preset voltage, judging whether the signals of the touch skin and the light-emitting signals are acquired. And if the signals of the touch skin and the lighting are determined to be obtained, controlling the light emitting module to emit light.
