Detailed Description

For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a light-emitting control system 1000 of an epilator in accordance with an embodiment of the present application. As shown in fig. 1, the epilator luminescence control system 1000 includes an energy storage module 10, a luminescence module 20, an imaging module 30, a control module 40 and a color detection module 50. The energy storage module 10 is electrically connected to the light emitting module 20, and the control module 40 is electrically connected to the energy storage module 10, the imaging module 30 and the color detection module 50, respectively.

Specifically, the energy storage module 10 is configured to be charged in response to the first control signal output by the control module 40. The light emitting module 20 is configured to emit light, and the intensity of the light emitted by the light emitting module 20 and the voltage of the energy storage module 10 show a positive correlation, i.e. the intensity of the light emitted by the light emitting module 20 increases with the voltage of the energy storage module 10 and decreases with the voltage of the energy storage module 10. The imaging module 30 is configured to acquire an image of the skin and transmit the image of the skin to the control module 40, such that the control module 40 determines a first parameter from the image of the skin, the first parameter comprising a hair density of the skin and/or a number of hairs of the skin and/or a hair length of the skin. The color detection module 50 is configured to obtain RGB values of skin and hair, and transmit the RGB values to the control module 40, so that the control module 40 determines a second parameter according to the RGB values of skin and hair, where the second parameter includes a color of skin and/or a color of hair. The control module 40 is configured to output a first control signal to control the energy storage module 10 to charge to a target voltage matching the first parameter and the second parameter.

In practice, when the epilator is used by a user, the imaging module 30 can acquire an image of the skin in contact with the skin, and the color detection module 50 can acquire RGB values of the skin and the hair, wherein RGB represents colors of three color channels of red, green and blue, and various colors can be obtained by changing the three color channels of red (R), green (G) and blue (B) and overlapping the three color channels with each other. After the control module 40 obtains the image of the skin and the RGB values of the skin and the hair, the control module 40 determines a first parameter according to the image of the skin, wherein the first parameter includes a hair density of the skin, or a number of hairs of the skin, or a hair length of the skin, or a hair density and a number of hairs of the skin, or a hair density and a hair length of the skin, or a hair number and a hair length of the skin, or a hair density, a hair number and a hair length of the skin. The control module 40 is further capable of determining a second parameter from the RGB values of the skin and the hair, wherein the second parameter comprises the color of the skin, or the color of the hair, or the color of the skin and the color of the hair. The control module 40 can determine the related parameters (i.e. the first parameter and the second parameter) of the skin and the hair that are currently contacted, and then the control module 40 can determine the duration of outputting the first control signal according to the first parameter and the second parameter to control the duration of charging the energy storage module 10, so as to control the energy storage module 10 to be charged to the target voltage matched with the first parameter and the second parameter.

For example, in one embodiment, the first parameter comprises a hair density, a number of hairs, and a length of hairs of the skin, the second parameter comprises a color of the skin and a color of the hairs, and the first parameter and the second parameter are each in positive correlation with the target voltage. Taking the hair density as an example, if the control module 10 determines that the hair density of the skin is higher, the time period for charging the energy storage module 10 is increased to increase the target voltage, so as to increase the intensity of the light emitted by the light emitting module 20; conversely, if it is determined that the hair density of the skin is smaller, the period of time for charging the energy storage module 10 is reduced to reduce the target voltage, thereby reducing the intensity of the light emitted from the light emitting module 20. The number of hairs, the length of the hairs, the color of the skin and the specific implementation process of the color of the hairs are similar to those of the hairs in terms of hair density, and are not repeated here.

In this embodiment, the first parameter and the second parameter determine the charging time of the energy storage module 10 to determine the voltage (i.e. the target voltage) at the end of charging the energy storage module 10, and the voltage of the energy storage module 10 determines the intensity of the light emitted by the light emitting module 20, and in summary, the first parameter and the second parameter determine the intensity of the light emitted by the light emitting module 20 (i.e. the energy of the emitted light). Therefore, the energy of emitted light is automatically adjusted according to the related parameters of skin and hair, and compared with the mode of manually selecting gears in the related technology, on one hand, the depilating instrument can output enough energy to destroy skin hair follicles to prevent hair growth so as to achieve the purpose of depilating, namely, a better depilating effect is maintained; on the other hand, the burning pain of the skin when the user uses the depilatory instrument can be reduced, so that the user has better experience.

In an embodiment, as shown in fig. 2, the energy storage module 10 includes a switching tube 11, a transformer 12 and an electrolytic capacitor 13 electrically connected in sequence, and the switching tube 11 is further electrically connected to the control module 40.

The switch tube 11 is used for being turned on when the control module 40 outputs a first control signal, so that the transformer 12 charges the electrolytic capacitor 13. The switching tube 11 is further configured to be turned off when the control module 40 stops outputting the first control signal, so that the transformer 12 stops charging the electrolytic capacitor 13.

Specifically, the primary winding of the transformer 12 is connected to a power source (not shown), and the secondary winding of the transformer 12 is connected to an electrolytic capacitor 13. When the control module 40 stops outputting the first control signal, the switching tube 11 is in a conducting state, at this time, the power supply stores energy for the primary winding of the transformer 12, the voltage in the primary winding rises, the secondary winding does not work, and the voltage of the electrolytic capacitor 13 drops.

When the control module 40 outputs the first control signal, the switching tube 11 is in an off state, and at this time, the primary winding of the transformer 12 transfers energy to the secondary winding, and the secondary winding charges the electrolytic capacitor 13. The voltage of the electrolytic capacitor 13 rises until the voltage at both ends thereof rises to the target voltage to satisfy the light emitting requirement of the light emitting module 20. Then, the control module 40 stops outputting the first control signal again to stop charging the energy storage module 10.

The above control process is repeated, the switching tube 11 can be turned on and off periodically, and the transformer 12 charges the electrolytic capacitor 13 periodically. The switch tube 11, the transformer 12 and the electrolytic capacitor 13 are combined to form the energy storage module 10, the control module 40 is used for controlling the on-off of the switch tube 11 to realize the control of charging and discharging the electrolytic capacitor 13, and the control mode is simple and the reaction is sensitive.

In this embodiment, the switching tube 11 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, or the like.

In one embodiment, the light module 20 includes a light tube. The lamp may be an IPL lamp, and the light emitted by the IPL lamp may be emitted to the skin of the user. The color of the light emitted by the lamp tube is not limited, and the light can be color light, compound light and the like, and the specific wavelength and frequency of the lamp tube are determined according to the use condition.

In one embodiment, imaging module 30 includes a camera. One or more cameras are provided on the epilator and are made to automatically photograph the contacted skin when the epilator is in contact with the skin, and the photographed image is transmitted to the control module 40. The control module 40 may identify the image according to a preset pattern to determine the hair density of the skin, and/or the number of hairs of the skin, and/or the hair length of the skin. Wherein, in some embodiments, the control module 40 may process the received images using a trained Machine Learning Model (MLM). The MLM may be of any suitable MLM type, e.g. classical machine learning model, which performs feature extraction, such as using a support vector machine, decision tree, random forest, etc. Further, the MLM evaluates each image to determine the hair density of the skin, and/or the number of hairs of the skin, and/or the hair length of the skin.

In an embodiment, the control module 40 may employ a micro control unit (Microcontroller Unit, MCU) or a digital signal processing (Digital Signal Processing, DSP) controller, or the like. For example, the control module 400 adopts an MCU chip, the MCU chip is internally integrated with various functions and peripherals such as I/O, A/D, a timer, a counter and the like, and the MCU chip can adopt different models such as a 51-series singlechip, a PIC-series singlechip and the like according to the needs.

In one embodiment, the color detection module 50 includes a color light digital sensor. When the epilator is in contact with the skin, the color light digital sensor is able to read the color of the contacted skin and hair and transmit the received RGB values of the skin and hair to the control module 40. After receiving the RGB values, the control module 40 converts the RGB values into corresponding color values, i.e. determines the skin color and the hair color.

In one embodiment, as shown in fig. 3, the light emission control system 1000 of the epilator further includes a cooling module 60, and the cooling module 60 is electrically connected to the control module 40.

Specifically, the control module 40 is further configured to output a second control signal to control the refrigeration power of the refrigeration module 60 to be a target power matched with the first parameter and the second parameter. The refrigeration module 60 is used for cooling the skin.

In practical applications, the cooling power of the cooling module 60 is matched with the first parameter and the second parameter, that is, the cooling power is changed along with the change of the first parameter and the second parameter, so as to change the cooling temperature of the cooling module 60. For example, in some embodiments, the first parameter is the number of hairs and the second parameter is the color of the hairs, and both the first parameter and the second parameter are in positive correlation with the cooling power. Specifically, the control module 10 increases the cooling power if it determines that the more the number of hairs is, the darker the hair color is, and decreases the cooling power if it does not.

Furthermore, the control of the intensity of the emitted light of the light emitting module 20 can be combined, so that when the intensity of the emitted light is high, the refrigerating module 60 can also have high refrigerating power, so that the temperature of the contacted skin can be reduced, and the burning sensation of the skin when a user uses the dehairing instrument can be reduced; it is also possible to achieve a smaller cooling power for the cooling module 60 when the intensity of the emitted light is smaller, and to maintain a better hair removal effect.

In one embodiment, the refrigeration module 60 includes a refrigeration element employing a semiconductor refrigeration scheme (i.e., a semiconductor refrigeration element), for example, the refrigeration module 60 includes a TEC (Thermoelectric cooler, semiconductor refrigerator).

When the user uses the epilating apparatus, the control module 40 outputs a second control signal to the cooling module 60, and the cooling module 60 starts the cooling function. The refrigerating module 60 uses the semiconductor refrigerating element to perform refrigeration, and can realize a rapid refrigerating effect by utilizing the characteristic that the thermal inertia of the semiconductor refrigerating element is very small. By providing the cooling module 60, the heat of the light emitting module 20 can be reduced and the skin can be temporarily paralyzed to reduce the tingling sensation of the hair removal.

In another embodiment, referring to fig. 3, the light-emitting control system 1000 of the epilator further includes a touch module 70 and a touch chip U1. The contact module 70 is electrically connected to the touch chip U1, and the touch chip U1 is electrically connected to the control module 40.

In particular, the contact module 70 is used to form a sense capacitance with the skin in contact. The touch chip is used for collecting capacitance change signals of the sensing capacitor and transmitting the capacitance change signals to the control module 40. The control module 40 is further configured to output a third control signal to control the emission module 20 to emit light when the voltage of the energy storage module 10 is charged to the target voltage and the variation of the capacitance variation signal exceeds a preset threshold.

In this embodiment, when the user uses the epilator, if the surface of the epilator emitting light contacts the skin, a sensing capacitance can be formed between the skin and the contact module 70. Specifically, since the skin of the human body carries a certain charge, when one surface of the epilator emitting light contacts the skin, a capacitive substrate can be formed with the contacted skin, and the contact module 70 is equivalent to another substrate, so as to form a sensing capacitor.

Further, since the contact module 70 is connected to the touch chip U1, the touch chip U1 can detect the capacitance change of the sensing capacitor. In addition, the skin of the human body has certain charges, so that the volume change generated by the fact that the surface of the dehairing instrument emitting light contacts the skin of the human body is different from the volume change generated by the fact that the surface of the dehairing instrument emitting light contacts other positions, such as clothes, a table top and the like, wherein the volume change generated by the fact that the surface of the dehairing instrument emitting light contacts the skin of the human body is more obvious. Therefore, the touch chip U1 can effectively detect whether the touch chip U1 is in contact with the skin by changing the specific volume value, and when it is determined that the touch chip U1 is in contact with the skin, the detection result (i.e., the volume value change signal) is generated to the control module 40.

Then, after the capacitance change signal is obtained, the control module 40 also needs to determine whether the energy storage module 10 has been charged to the target voltage at the same time, so as to ensure that enough electric energy can be provided to the light emitting module 20. Only when the energy storage module 10 is charged to the target voltage, the control module 40 can control the dehairing instrument to shine, so that the safety problem caused by misoperation of a user can be reduced, and the working efficiency of the dehairing instrument is improved.

In one embodiment, the contact module 70 includes a flexible circuit board (Flexible Printed Circuit abbreviated as FPC).

In an embodiment, please continue to refer to fig. 3, the light-emitting control system 1000 of the epilator further includes a trigger module 80, and the trigger module 80 is electrically connected to the light-emitting module 20 and the control module 40, respectively.

The triggering module 80 is configured to communicate the energy storage module 10 and the light emitting module 20 in response to the third control signal, and discharge the energy storage module 10 to the light emitting module 20 to control the light emitting module 20 to emit light. When the control module 40 determines that the voltage of the energy storage module 10 is the target voltage and obtains the capacitance change signal, the control module 40 outputs a third control signal to the trigger module 80, and the trigger module 80 communicates the energy storage module 10 and the light emitting module 20 according to the third control signal, so that the energy storage module 10 discharges to the light emitting module 20, and the gas in the light emitting module 20 is excited to achieve the effect of emitting light.

In an embodiment, referring to fig. 3, the light-emitting control system 1000 of the epilator further includes a timing module 90, and the timing module 90 is electrically connected to the control module 40.

In this embodiment, the control module 40 is further configured to output a timing signal to the timing module 90 according to a target timing duration when the third control signal is output, where the target timing duration is a duration that matches the first parameter and the second parameter. The timing module 90 is configured to start timing when receiving the timing signal, stop timing when the timing duration reaches the target timing duration, and send a stop lighting signal to the control module 40, so that the control module 40 stops outputting the third control signal.

Specifically, while the control module 40 outputs the third control signal to the triggering module 80 to cause the triggering module 80 to trigger the light emitting module 20 to emit light, the control module 40 also outputs the timing signal to the timing module 90 to cause the timing module 90 to start timing. That is, the timing module 90 starts timing while the light emitting module 20 emits light. The target timing duration of the timing module 90 is determined by the timing signal, the timing signal is determined by the first parameter and the second parameter, and the target timing duration is determined by the first parameter and the second parameter, that is, the target timing duration is the duration matched with the first parameter and the second parameter. Then, when the time period counted by the timing module 90 reaches the target time period, the timing module 90 stops timing and sends a stop light emitting signal to the control module 40. The control module 40 stops outputting the third control signal after receiving the light emission stopping signal, and the light emitting module 20 stops emitting light.

In this embodiment, control of the duration of the light emitted by the light emitting module 20 (i.e., the light emission duration) is achieved to achieve reduction of the light emission duration when the intensity of the light emitted by the light emitting module 20 is large, so as to reduce the burning sensation of the skin when the user uses the epilator; and to achieve a longer luminous duration when the intensity of the light emitted by the luminous module 20 is small, so as to enhance the depilating effect.

In one embodiment, referring to fig. 3, the light emission control system 1000 of the epilator further comprises a voltage detection module 100. The voltage detection module 100 is electrically connected between the energy storage module 10 and the control module 40.

The voltage detection module 100 is configured to detect a voltage of the energy storage module 10 and output a first voltage signal to the control module 40. The control module 40 is further configured to output a first control signal to control the energy storage module 10 to charge when the first voltage signal is less than the target voltage; the control module 40 is further configured to output a fourth control signal to control the energy storage module 10 to stop charging when the first voltage signal is not less than the target voltage.

In one embodiment, the voltage detection circuit 100 includes a plurality of resistors connected in series, one end of the voltage detection circuit 100 is connected to the energy storage module 10, and detects the voltage of the energy storage module 10 according to the resistor voltage division principle, and converts the detected voltage value into a corresponding voltage signal to be transmitted to the control module 40.

Then, a comparison circuit is provided in the control module 40, and compares the received voltage signal with the internal software setting voltage. When the voltage value represented by the voltage signal is smaller than the internal software setting voltage (the target voltage in this embodiment), the control module 40 outputs a first control signal; when the voltage value represented by the voltage signal is higher than the internal software setting voltage, the control module 40 outputs a fourth control signal. The control module 40 is electrically connected with the energy storage module 10 to detect the voltage of the energy storage module 10 in real time, and the detected voltage value of the energy storage module 10 is compared with the software set voltage inside the control module 40 to output a first control signal or a fourth control signal. When the control module 40 with higher precision is adopted, the precision of the voltage set by the internal software is also higher, so that the control precision of the control module 40 is improved, the difference between the voltage of the energy storage module 10 and the target voltage is kept in a small range, and the difference is always kept in a safe voltage range.

In this embodiment, by directly connecting the control module 40 and the energy storage module 10 to detect the voltage of the energy storage module 10 in real time, the control module 40 controls whether the energy storage module 10 stores energy in real time according to the detected voltage; the voltage of the energy storage module 10 can be always maintained in a complete range by improving the precision of the control module 40, so that the light-emitting control system 1000 of the dehairing instrument is more stable.

It should be noted that the hardware configuration of the light emission control system 1000 of the epilator as shown in fig. 2 or 3 is only one example, and that the light emission control system 1000 of the epilator may have more or less components than shown in the figures, may combine two or more components, or may have different configurations of components, and the various components shown in the figures 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, as shown in fig. 4, the light-emitting control system 1000 of the epilator further includes a driving module 110, and the driving module 110 is electrically connected between the control module 40 and the energy storage module 10. Specifically, the driving module 110 is configured to output a driving signal to control the energy storage module 10 to charge in response to the first control signal, and to turn off the driving to control the energy storage module 10 to stop charging in response to the fourth control signal output from the control module 110. In some embodiments, the driving unit 201 includes a PFC (power factor correction) chip.
