The resistor R2 adopts a variable resistor.
The implementation working principle of the circuit designed and adopted by the application is as follows:
the processor module is connected to a first power supply (i.e., in1 power supply in the figure) to control the voltage of the first power supply.
When the power is supplied at low power, for example, the processor module precisely controls the voltage of the first power supply to vary between 0 and 5V, and the comparator U5 outputs a high level because the reference voltage Ref connected to the comparator U5 is set to 5.2V, at this time, one input terminal of the exclusive nor gate U3 is at a low level, one input terminal is at a high level, and the exclusive nor gate U3 outputs a low level to turn off the MOS transistor Q5. After the capacitor C4 is fully charged, the input end of the not gate U1 is at a high level, so that the gate of the MOS transistor Q3 is converted to a low level by the not gate U6, the gate of the MOS transistor Q4 is at a high level, the MOS transistor Q3 is turned off, and the MOS transistor Q4 is turned on. The high level is output through the conversion of the NOT gates U1 and U2 to charge the capacitor C6, and after the capacitor C6 is fully charged, the two input ends of the exclusive OR gate U3 are both high level, so that the high level is output to conduct the MOS transistor Q5. The first power supply circuit is connected to the input circuit for supplying power.
When the high power supply is performed, the processor module increases the voltage of the first power supply, for example, to 6V in the present embodiment, and the output of the comparator U5 is at a low level. Because of the discharging action of the capacitor C4 and the capacitor C6, one input end of the exclusive or gate U3 is at a low level, one input end maintains a high level, and the exclusive or gate U3 outputs a low level to turn off the MOS transistor Q5 in advance. After the capacitor C4 is completely discharged, the input end of the NOT gate U1 is at a low level, the grid electrode of the MOS tube Q3 is at a high level after being converted by the NOT gate U6, the grid electrode of the MOS tube Q4 is at a low level, the MOS tube Q3 is conducted, the MOS tube Q4 is closed, and the switching of a power supply circuit is completed. The input end of the NOT gate U1 is low level, so that the output of the NOT gate U2 is converted into low level, the capacitor C6 starts to discharge at the moment, after the capacitor C6 is discharged, the two input ends of the exclusive-OR gate U3 are low level, the exclusive-OR gate U3 outputs high level to turn on the MOS tube Q5 again, and the output circuit is connected with the second power supply circuit to supply power.
When it is desired to switch back to low power, the processor module regulates down the voltage of the first power supply, e.g., to 5V, at which time the comparator U5 output goes high. Because of the charging action of the capacitor C4 and the capacitor C6, one input end of the exclusive or gate U3 is maintained at a low level, and one input end of the exclusive or gate U3 becomes a high level, and the exclusive or gate U3 outputs a low level to turn off the MOS transistor Q5 in advance. After the capacitor C4 is fully charged, the input end of the NOT gate U1 is at a high level, the grid of the MOS tube Q3 is at a low level after being converted by the NOT gate U6, the grid of the MOS tube Q4 is at a high level, the MOS tube Q3 is closed, the MOS tube Q4 is conducted, and the switching of a power supply circuit is completed. The input end of the NOT gate U1 is high level, so that the output of the NOT gate U2 is converted into high level, the capacitor C6 starts to charge at the moment, after the capacitor C6 is fully charged, the two input ends of the exclusive-OR gate U3 are both high level, the exclusive-OR gate U3 outputs high level to turn on the MOS tube Q5 again, and the output circuit is connected with the first power supply circuit to supply power.
The conventional method is to switch the power supply by a control method such as a chip or an MCU, and the like, at the moment, the time length is longer in the switching process, the efficiency is lower in the switching process, and the timeliness requirement on the adjustment of the light-emitting module is higher when the beauty mask is used, so that the timeliness cannot be effectively met by the control method of the power supply switching through the chip or the MCU, and the like in the conventional scheme. In this embodiment, the first power supply circuit not only can be used as a power supply circuit, but also can be used as a switching signal circuit, so that the real-time switching performance according to the power requirement is stronger, the signal control circuit of the processor module can be simplified, the control structure is simplified, the reliability is enhanced, and the cost is reduced. Meanwhile, through the cooperation of the two circuits, the fine control at low voltage can be realized, and the problems of high heat quantity, high loss and influence on the safety and service life of the circuit at high voltage can be avoided. In addition, the processor module realizes the alternating treatment mode between the low power and the high power by controlling the alternating of the first power supply voltage between 5V and 5.5V, wherein, for example, the power supply voltage of the second power supply circuit is 24V or other higher voltages, so that the switching and the alternating of the high power supply circuit and the low power supply circuit can be realized rapidly, the irradiation mode can be switched, the power supply circuits can be switched simultaneously, and the power supply and the protection circuit can be saved to the greatest extent.
In the control branch, a hierarchical delay circuit is formed by matching a capacitor C4, a capacitor C6, an NOT gate U1, an NOT gate U2 and an exclusive OR gate U3, when each circuit is switched, the MOS tube Q5 is closed firstly, the circuit is switched after a first layer of delay formed by the capacitor C4, and the MOS tube Q5 is switched again after the circuit is switched, and the MOS tube Q5 is switched on again after a second layer of delay formed by the capacitor C6 to supply power, so that the impact of follow-up circuits such as uncontrollable voltage fluctuation conditions, overlarge fluctuation light generating modules and the like in the circuit switching process is prevented.

Example III
In the prior art, the light emission is usually performed by adopting inherent light emission parameters, and the target user using the beauty mask has individual differences, so that the beauty mask cannot well adapt to the user's requirements, therefore, in the beauty mask of the embodiment of the present application, a processor module, a detection module and a light generation module are provided, and the processor module is connected with the detection module and the light generation module, and dynamically adjusts the light of the beauty mask by the following method, which can be referred to as a flow diagram shown in fig. 3, specifically can be:
a1, the detection module collects target facial skin state parameters of a target user when the face mask is used, and sends the target facial skin state parameters to the processor module (namely a first MCU in the figure);
a2, the processor module determines physiotherapy state information of the target user according to the target facial skin state parameters;
a3, the processor module determines the light adjusting parameters of the light generating module according to the physiotherapy state information;
and A4, the processor module adjusts the light emission of the light generation module according to the light adjustment parameter.
The skin state parameters may include a degree of coverage of oil on the skin surface, a degree of relaxation of pores, and the like, and since skin cells are metabolized and the like when the skin is treated by the cosmetic mask, oil and the like are generated, the effect of the treatment can be judged by the degree of coverage of oil, the higher the degree of coverage of oil is, the better the effect of the treatment is, the better the treatment state can be correspondingly characterized as the treatment state. The state of physiotherapy can also be represented by the degree of pore relaxation, which can be understood as the degree of pore expansion, and the greater the degree of pore expansion, the easier the oil stain and the like in the pores are removed, and the better the physiotherapy state is.
The better the physiotherapy state is, the light intensity can be reduced at the moment, and the light adjusting parameters can be the light intensity reduction; the worse the physical therapy state is, the intensity of light can be improved, and the light adjusting parameter can be the intensity of light. Therefore, physical therapy state information of a user is dynamically acquired, and light is adjusted to adapt to physical therapy requirements of the user, so that physical therapy effect and accuracy are improved.
In one possible implementation, in the existing solutions, when the initial condition setting of the cosmetic mask is performed, it is generally in the form of a system default, which, due to individual differences of the users, does not adapt perfectly to each user. Or the mode of setting after the manual judgment, when the manual judgment is performed, the deviation condition exists due to different understanding degrees of the judgment staff, so that the accuracy is lower when the initial physiotherapy parameters of the beauty mask are set. For this reason, the present application provides the following method to solve the above problem, and may refer to the flow chart shown in fig. 4, specifically:
b1, the detection module acquires an initial face image of the target user and sends the initial face image to the processor module;
b2, the processor module determines initial physiotherapy parameters corresponding to the target user according to the initial facial image;
b3, the processor module determines initial emission parameters of the light generation module according to the initial physiotherapy parameters;
and B4, the processor module controls the light generation module to emit light according to the initial emission parameters.
The detection module may include a camera, and the initial facial image of the target user is acquired through the camera, where the initial facial image may be understood as a facial image of the target user before the beauty mask is not used.
The initial facial image can be subjected to feature extraction to obtain feature data, wherein the feature data can be RGB values and the like, and then the skin dryness, pore diastole, acne mark size, whether acne exists or not and the like of a target user are extracted according to the feature data; initial physiotherapy parameters are determined based on skin dryness, pore relaxation, size of acne marks, presence or absence of acne, etc. The greater the skin dryness, the greater the physiotherapy force; the greater the pore dilating degree is, the smaller the physiotherapy force is; the larger the acne mark is, the larger the physiotherapy force is; the more the number of acnes, the greater the physical therapy intensity. The physiotherapy intensity can be understood as the intensity of light when physiotherapy is carried out, and the larger the physiotherapy intensity is, the higher the intensity of light can be, and the smaller the physiotherapy intensity is, the smaller the intensity of light is. The intensity of the light is within a preset range, which is set by an empirical value or historical data.
