[0024] ​In the following, only certain exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are considered to be exemplary in nature rather than limiting.

[0025] Figure 1 A structural block diagram of a beauty device according to an embodiment of the present application is shown.

[0026] As Figure 1 shown, the beauty device 100 includes a controller 11, a first driving module 12, a second driving module 13, a first light source 14 and a second light source 15. The first driving module 12 and the second driving module 13 are connected with the controller 11 respectively. The first light source 14 is connected with the first driving module 12, so that the controller 11 controls the first driving module 12 to drive the first light source 14 to emit light. The second light source 15 is connected with the second driving module 13, so that the controller 11 controls the second driving module 13 to drive the second light source 15 to emit light. Wherein, the irradiance of the first light source 14 is greater than the irradiance of the second light source 15. The irradiance of the first light source 14 being greater than the irradiance of the second light source 15 can be that the radiant flux per unit area emitted by the first light source 14 is greater than the radiant flux per unit area emitted by the second light source 15.

[0027] Exemplarily, please refer to Figure 2 , the first light source 14 can be a COB (Chip On Board, COB for short) light 141, and the second light source 15 can be an LED light source 151. Since the packaging mode of the COB light source 141 is a direct chip on board packaging, this packaging mode is to directly paste the LED chip on the mirror metal substrate with high reflectivity, and the packaging mode of the LED light source 151 is a pin packaging or a patch packaging. Compared with the packaging mode of the LED light source 151, the direct chip on board packaging adopted by the COB light source 141 can make the LED chips on the COB light source 141 more compact, so that the light intensity of the COB light source 141 is greater than the light intensity of the LED light source 151 on the same area. It should be noted that the related art beauty device is only provided with the LED light source, and the irradiance is low, so that the beauty effect of the related art beauty device is poor. While the beauty device 100 of the present application not only has the second light source 15 with low irradiance, but also has the first light source 14 with high irradiance, for example, the irradiance of a single LED chip in the LED light source 151 can be 6mW / cm 2 , and the irradiance at a distance of 5cm from the surface of the COB light source 141 is 90mW / cm 2 , so that the beauty device 100 in the present application has better beauty effect.

[0028] In actual application, when the cosmetic device 100 needs to work in the high-brightness mode, the controller 11 can control the first driving module 12 to drive the first light source 14 to emit light and control the second driving module 13 to drive the second light source 15 to emit light at the same time; when the cosmetic device 100 does not need to work in the high-brightness mode, the controller 11 can only control the second driving module 12 to drive the second light source 15 to emit light.

[0029] The above scheme, by setting the cosmetic device 100 including the controller 11, the first light source 14 connected with the controller 11 through the first driving module 12, and the second light source 15 connected with the controller 11 through the second driving module 13, so that the controller 11 can control the first driving module 12 to drive the first light source 14 to emit light, and the controller 11 can control the second driving module 13 to drive the second light source 15 to emit light, and because the irradiance of the first light source 14 is greater than that of the second light source 15, the cosmetic device 100 can not only use the second light source 15 with lower irradiance to irradiate the skin of the user, but also use the first light source 14 with higher irradiance to irradiate the skin of the user, so that the cosmetic device 100 has a super-bright light effect, thereby effectively improving the cosmetic effect of the cosmetic device 100.

[0030] In an embodiment, as shown in Figure 2 The first light source 14 includes a plurality of COB light sources 141, each COB light source 141 has a plurality of control terminals, the input end of the first driving module 12 is connected with the controller 11, and the plurality of output ends of the first driving module 12 are connected with the plurality of control terminals of each COB light source 141 one by one, so as to drive each COB light source 141 to emit light of multiple colors respectively.

[0031] Exemplarily, please refer to Figure 2For example, each COB light source 141 has a first control end and a second control end, and the first driving module 12 has a first output end out1 and a second output end out2. The first output end out1 of the first driving module 12 is connected to the first control end of each COB light source 141, and the second output end out2 of the first driving module 12 is connected to the second control end of each COB light source 141. When the controller 11 sends a driving signal to the first control end of each COB light source 141 through the first output end out1 of the first driving module 12, each COB light source 141 emits light of a first color. When the controller 11 sends a driving signal to the second control end of each COB light source 141 through the second output end out2 of the first driving module 12, each COB light source 141 emits light of a second color. When the controller 11 sends a driving signal to the first control end and the second control end of each COB light source 141 through the first output end out1 and the second output end out2 of the first driving module 12, each COB light source 141 emits light of the first color and light of the second color simultaneously. The light of the first color can be red light, and the light of the second color can be yellow light.

[0032] It should be noted that the number of control ends of each COB light source 141 includes two or more, the number of output ends of the first driving module 12 includes two or more, and the number of colors of light emitted by each COB light source 141 includes two or more. The number of control ends of each COB light source 141, the number of output ends of the first driving module 12, and the number of colors of light emitted by each COB light source 141 are not limited in the embodiments of the present application. For example, each COB light source 141 can emit at least one of red, yellow, green, and other colors.

[0033] The above scheme connects the input end of the first driving module 12 to the controller 11 and connects the multiple output ends of the first driving module 12 to the multiple control ends of each COB light source 141 one by one, so that the controller 11 can control the first driving module 12 to drive each COB light source 141 to emit light of multiple colors. This helps the multiple COB light sources 141 to emit light of different colors according to different beauty modes, thereby enriching the beauty effect of the beauty device 100.

[0034] In one embodiment, as shown in Figure 2 The first driving module 12 includes multiple first driving circuits 121, each first driving circuit 121 has one input end and one output end. The input ends of the multiple first driving circuits 121 are connected to the controller 11, and the output ends of the multiple first driving circuits 121 are connected to the multiple control ends of each COB light source 141 one by one, so that one first driving circuit 121 drives each COB light source 141 to emit light of one color.

[0035] For example, the first driving circuit 121 includes two, the input ends of the two first driving circuits 121 are connected with the controller 11, the output end out1 of one of the first driving circuits 121 constitutes the first output end out1 of the first driving module 12, and the output end out2 of the other first driving circuit 121 constitutes the second output end out2 of the first driving module 12, so that the output end out1 of one of the first driving circuits 121 is connected with the first control end of each COB light source 141, and the output end out2 of the other first driving circuit 121 is connected with the second control end of each COB light source 141, and the controller 11 can control one of the first driving circuits 121 to drive the plurality of COB light sources 141 to emit light of the first color, or control the other first driving circuit 121 to drive the plurality of COB light sources 141 to emit light of the second color, or simultaneously control the two first driving circuits 121 to drive the plurality of COB light sources 141 to emit light of the first color and light of the second color.

[0036] Preferably, as shown in Figure 2 , the output ends of the plurality of first driving circuits 121 and the plurality of control ends of each COB light source 141 can be directly connected or connected through current limiting resistors. The connection mode can be selected and adjusted according to actual needs, and the embodiments of the present application do not limit this.

[0037] In one embodiment, as shown in Figure 3 , the COB light source 141 includes a plurality of first LED chips D1 and a plurality of second LED chips D2, the first LED chips D1 are used to emit light of the first color, and the second LED chips D2 are used to emit light of the second color. For example, the plurality of first LED chips D1 can be 18 red LED chips, and the plurality of second LED chips D2 can be 18 yellow LED chips. The plurality of first LED chips D1 constitute a plurality of first series branches L1, for example, 18 red LED chips constitute two first series branches L1; the plurality of second LED chips D2 constitute a plurality of second series branches L2, for example, 18 yellow LED chips constitute two second series branches L2; the first ends of the plurality of first series branches L1 and the plurality of second series branches L2 are connected with the first power supply VCC1, the second ends of the plurality of first series branches L1 are connected and constitute the first control end of the COB light source 141, and the second ends of the plurality of second series branches L2 are connected and constitute the second control end of the COB light source 141.

[0038] Exemplarily, each first serial branch L1 is composed of a plurality of first LED chips D1 in series, for example, each first serial branch L1 is composed of 9 red LED chips in series, the first end of the first serial branch L1 is the positive electrode after the plurality of first LED chips D1 are connected in series, and the second end of the first serial branch L1 is the negative electrode after the plurality of first LED chips D1 are connected in series. Similarly, each second serial branch L2 is composed of a plurality of second LED chips D2 in series, for example, each second serial branch L2 is composed of 9 yellow LED chips in series, the first end of the second serial branch L2 is the positive electrode after the plurality of second LED chips D2 are connected in series, and the second end of the second serial branch L2 is the negative electrode after the plurality of second LED chips D2 are connected in series. This structure makes the COB light source 141 emit light of the first color, for example, red light, when the second end of the plurality of first serial branches L1 receives a low level, and makes the first LED chips D1 in the COB light source 141 extinguish when the second end of the plurality of first serial branches L1 receives a high level. Similarly, the COB light source 141 emits light of the second color, for example, yellow light, when the second end of the plurality of second serial branches L2 receives a low level, and makes the second LED chips D2 in the COB light source 141 extinguish when the second end of the plurality of second serial branches L2 receives a high level. Therefore, by providing a low level to the first control end of the COB light source 141, all the first LED chips D1 in the COB light source 141 can be controlled to emit light of the first color, and by providing a high level to the first control end of the COB light source 141, all the first LED chips D1 in the COB light source 141 can be controlled to extinguish. Similarly, by providing a low level to the second control end of the COB light source 141, all the second LED chips D2 in the COB light source 141 can be controlled to emit light of the second color, and by providing a high level to the second control end of the COB light source 141, all the second LED chips D2 in the COB light source 141 can be controlled to extinguish.

[0039] Preferably, as shown in FIG. 1, in the COB light source 141, the first control end of the COB light source 141 is grounded through the first voltage stabilizing diode ZD1, and the second control end of the COB light source 141 is grounded through the second voltage stabilizing diode ZD2. This structure can clamp the potential of the first control end and the second control end of the COB light source 141 by the first voltage stabilizing diode ZD1 and the second voltage stabilizing diode ZD2 respectively, thereby ensuring the stability of the light emission of the COB light source 141. Figure 3 In an embodiment, as shown in FIG. 1, the first control end and the second control end of the COB light source 141 are electrically connected to the output ends out1 and out2 of the two first driving circuits 121 through the connector CN in a detachable manner.

[0040] Figure 4

[0041] ​​Exemplarily, the connector CN can include a male head and a female head, the first control end and the second control end of the COB light source 141 are connected with the male head of the connector CN, the output ends out1 and out2 of the two first driving circuits 121 are connected with the female head of the connector CN, and the male head and the female head are detachably connected. In this way, the number of the COB light sources 141 assembled on the beauty device 100 can be flexibly controlled. It should be noted that Figure 4 Only the female head of the connector CN is shown, and the connection schematic diagram between the COB light source 141 and the male head of the connector CN is not shown.

[0042] In an embodiment, as shown in Figure 2 、 Figure 3 and Figure 5 , the first driving circuit 121 includes a first triode Q1, the base of the first triode Q1 is connected with the first end of a first resistor R1, the second end of the first resistor R1 constitutes the input end in of the first driving circuit 121, the emitter of the first triode Q1 is grounded, and the base of the first triode Q1 is connected with the emitter through a second resistor R2, the collector of the first triode Q1 is connected with a first power supply VCC1 through a third resistor R3, the collector of the first triode Q1 is connected with the first power supply VCC1 through a reverse flow prevention diode FD1, and the collector of the first triode Q1 constitutes the output end out of the first driving circuit 121. Wherein, the anode of the reverse flow prevention diode FD1 is connected with the collector of the first triode Q1, the cathode of the reverse flow prevention diode FD1 is connected with the first power supply VCC1, and the reverse flow prevention diode FD1 can be a Schottky diode.

[0043] Exemplarily, the first triode Q1 can be an NPN triode, the anode of the multiple first LED chips D1 connected in series in each COB light source 141 and the anode of the multiple second LED chips D2 connected in series are connected with the first power supply VCC1, the cathode of the multiple first LED chips D1 connected in series in each COB light source 141 is connected with the collector of the first triode Q1 of the first driving circuit 121 (i.e. the output end out of the first driving circuit 121), and the cathode of the multiple second LED chips D2 connected in series in each COB light source 141 is connected with the collector of the first triode Q1 of the first driving circuit 121.

[0044] The drive signal sent by the controller 11 to the first drive circuit 121 can be a first PWM signal. The operation of the first drive circuit 121 includes: when the controller 11 sends the first PWM signal to the second terminal of the first resistor R1 (i.e., the input terminal in of the first drive circuit 121), during the duration of the high level in the first PWM signal, the emitter junction and collector junction of the first transistor Q1 are both in a forward biased conducting state, the first transistor Q1 is in a saturated state, and the collector of the first transistor Q1 outputs a low level, thereby driving multiple first LED chips D1 in each COB light source 141 to emit light of the first color and / or driving multiple second LED chips D2 in each COB light source 141 to emit light of the second color; during the duration of the low level in the first PWM signal, the emitter junction and collector junction of the first transistor Q1 are both in a reverse biased state, the first transistor Q1 is in a cutoff state, and the multiple first LED chips D1 and / or multiple second LED chips D2 in each COB light source 141 do not form a circuit and are extinguished. It should be noted that the type of the first transistor Q1 can be selected and adjusted according to actual needs, and this application does not impose any restrictions on it.

[0045] In addition, the controller 11 can also adjust the light emission time of the COB light source 141 driven by the first driving circuit 121 by adjusting the duty cycle of the first PWM signal, thereby controlling the light emission brightness of the COB light source 141. For example, the larger the duty cycle of the first PWM signal, the longer the light emission time of the COB light source 141 driven by the first driving circuit 121, and the brighter the corresponding light emission brightness.

[0046] In the above scheme, since the high and low level changes rapidly in the first PWM signal, the first transistor Q1 is prone to generating a brief reverse current during the state switching process. By setting an anti-reverse current diode FD1 between the collector of the first transistor Q1 and the first power supply VCC1, the reverse current can be consumed by the loop formed by the anti-reverse current diode FD1 and the third resistor R3, thereby effectively preventing the current from flowing in reverse and protecting other components in the first drive circuit 121 from the influence of reverse voltage.

[0047] In one implementation, such as Figure 2 As shown, the second light source 15 includes multiple LED light sources 151, each emitting a different color; the second driving module 13 includes multiple second driving circuits 131, each having an input terminal and an output terminal; the input terminals of the multiple second driving circuits 131 are respectively connected to the controller 11, and the output terminals of the multiple second driving circuits 131 are connected one-to-one with the multiple LED light sources 151. The controller 11 is used to control each second driving circuit 131 to drive the corresponding LED light source 151 to emit light.

[0048] Exemplarily, taking 4 as an example for the plurality of LED light sources 151 and the plurality of second driving circuits 131. The input ends of the 4 second driving circuits 131 are respectively connected with the controller 11, the output ends of the 4 second driving circuits 131 are connected with the 4 LED light sources 151 one by one, and the controller 11 respectively controls the 4 second driving circuits 131 to drive the corresponding LED light sources 151 to emit light. For example, the controller 11 can make the first second driving circuit 131 drive the first LED light source 151 to emit light by sending a driving signal to the first second driving circuit 131.

[0049] Among them, the 4 LED light sources 151 can emit red light, yellow light, blue light and infrared light one by one. Since the controller 11 can individually control each second driving circuit 131 to drive the corresponding LED light source 151 to emit light, it can not only achieve the control of the beauty device 100 to emit any one color of light among red light, yellow light, blue light and infrared light, but also achieve the control of the beauty device 100 to emit at least two colors of light among red light, yellow light, blue light and infrared light.

[0050] Since the structure of the LED light source 151 is similar to that of the COB light source 141, the structure of the LED light source 151 can refer to the structure of the COB light source 141 in Figure 3 For example, each LED light source 151 includes a plurality of LED chips emitting the same color light, the plurality of LED chips can form a plurality of third series branches, and the plurality of third series branches are connected in parallel. It should be noted that the connection mode of the plurality of LED chips in each LED light source 151 can be selected and adjusted according to actual needs, and the present application is not limited thereto.

[0051] In addition, the structure of the second driving circuit 131 is similar to that of the first driving circuit 121 and the working principle, so the structure of the second driving circuit 131 can refer to the structure of the first driving circuit 121 in Figure 5 The principle of the second driving circuit 131 driving the LED light source 151 can refer to the principle of the first driving circuit 121 driving the COB light source 141, which will not be described here.

[0052] The above scheme, by setting the second light source 15 includes a plurality of LED light sources 151, and setting the second drive module 13 includes a plurality of second drive circuits 131, and the input end of the plurality of second drive circuits 131 is connected with the controller 11 respectively, the output end of the plurality of second drive circuits 131 is connected with the plurality of LED light sources 151 one by one, can make the controller 11 control each second drive circuit 131 drive the corresponding LED light source 151 to emit light of corresponding color, and then realize controlling the beauty device 100 to emit different color light. Because the energy of different color light is different, the beauty effect of different color light irradiating the skin of the user is different, so different efficacy of the beauty effect can be met.

[0053] In practical application, please refer to Figure 2 , the controller 11 controls the first drive module 12 to drive the plurality of COB light sources 141 to emit light and controls the second drive module 13 to drive the plurality of LED light sources 151 to emit light at the same time, so that the beauty device 100 can work in high-brightness mode, and by controlling the plurality of COB light sources 141 and the plurality of LED light sources 151 to emit light of different colors, the beauty device 100 can be further controlled to work in different beauty modes in high-brightness mode, such as skin tendering, acne removing, penetration promoting, whitening, oil controlling, repairing, anti-early aging, soothing, etc. The controller 11 controls the first drive module 12 to drive the plurality of COB light sources 141 to be extinguished and controls the second drive module 13 to drive the plurality of LED light sources 151 to emit light, so that the beauty device 100 can work in low-brightness mode, and by controlling the plurality of LED light sources 151 to emit light of different colors, the beauty device 100 can be further controlled to work in different beauty modes in low-brightness mode. In this way, different efficacy of the beauty effect can be met.

[0054] In an embodiment, as shown in Figure 1 and Figure 6 , the beauty device 100 further includes an atomization module 21, the atomization module 21 includes an atomization sheet 211, a boost inductor 212, a gate driver 213 and a transistor M1.

[0055] The boost inductor 212 has a primary end, a secondary end and a common end, the primary end of the boost inductor 212 is connected with the second power supply VCC2, the secondary end of the boost inductor 212 is connected with the first end of the atomization sheet 211, and the common end of the boost inductor 212 is connected with the second end of the atomization sheet 211.

[0056] The first end and the second end of the atomizing piece 211 are also grounded through a third voltage stabilizing diode ZD3, so as to stabilize the voltage of the first end and the second end of the atomizing piece 211. The atomizing piece 211 has a plurality of atomizing holes, for example, 1200 atomizing holes, and the diameter of the atomizing holes can be 8 μm. The spraying distance of the atomizing piece 211 can reach 20 cm, and the atomizing diameter of the atomizing piece 211 can reach 15 mm. The atomizing piece 211 is connected to a container through a cotton strip, and the container is used to contain skin care liquid. The atomizing piece 211 sucks the skin care liquid from the container through the cotton strip. The skin care liquid can be water or water-based toner.

[0057] The input end in+ and in- of the gate driver 213 are connected to the controller 11 through a fourth resistor R4, the output end out of the gate driver 213 is connected to the gate of the transistor M1 through a fifth resistor R5, the drain of the transistor M1 is connected to the common end of the boost inductor 212, and the source of the transistor M1 is grounded. The transistor M1 can be an NMOS tube or a PMOS tube, and the type of the transistor M1 can be selected and adjusted according to actual needs. The embodiment of the present application takes the transistor M1 as an NMOS tube as an example for description.

[0058] The controller 11 is used to control the gate driver 213 to drive the transistor M1 to periodically turn on and turn off, so as to provide the second PWM signal to the common end of the boost inductor 212, so that the power supply voltage provided by the second power supply VCC2 is transmitted to the atomizing piece 211 after being boosted by the boost inductor 212, so as to control the atomizing piece 211 to atomize the skin care liquid. Specifically, when the gate driver 213 receives the second PWM signal sent by the controller 11, the gate driver 213 sends the second PWM signal after boosting to the transistor M1, so as to stably drive the transistor M1 to periodically turn on and turn off, so that the second power supply VCC2 applies the power supply voltage provided by the second power supply VCC2 to the primary inductor coil between the primary end and the common end through the primary end of the boost inductor 212, and the secondary inductor coil between the secondary end and the common end is connected to the primary inductor coil through magnetic coupling, and the number of turns of the secondary inductor coil is greater than that of the primary inductor coil. Therefore, the power supply voltage can be boosted and output to the atomizing piece 211, so as to control the atomizing piece 211 to atomize the skin care liquid.

[0059] The above scheme can make the beauty device 100 have skin care effect on the basis of having beauty function, so as to simultaneously perform beauty and skin care on the user's skin by using the beauty device 100, prevent dry skin from being damaged for a long time under light, and help to improve the beauty effect.

[0060] In one example, as shown in FIG. 1, the beauty device 100 includes a skin care device 200. Figure 6As shown, the first capacitor C1 is connected between the gate and the source of the transistor M1. When the transistor M1 is turned on and turned off at a high speed, the change rate of the drain-source voltage of the transistor M1 is high, which causes the gate-drain capacitance to be coupled to the gate voltage, so that the gate voltage rises instantaneously, which may cause the transistor M1 to be mistakenly turned on in the off state. By connecting the first capacitor C1 between the gate and the source of the transistor M1, the gate-source capacitance can be increased, so as to reduce the induced voltage of the gate voltage of the transistor M1, thereby preventing the transistor M1 from being mistakenly turned on.

[0061] In an embodiment, as shown in Figure 1 and Figure 6 As shown, the cosmetic device 100 further comprises a first detection module 31, and the first detection module 31 comprises a first voltage dividing resistor Ra and a second voltage dividing resistor Rb. The first end of the first voltage dividing resistor Ra is connected to the first end of the atomizing piece 211, the second end of the first voltage dividing resistor Ra is connected to the first end of the second voltage dividing resistor Rb, the second voltage dividing resistor Rb is grounded, and the connection point of the first voltage dividing resistor Ra and the second voltage dividing resistor Rb is connected to the controller 11 to provide a detection voltage of the atomizing piece 211 to the controller 11, so that the controller 11 determines whether the state of the atomizing piece 211 is abnormal according to the detection voltage.

[0062] For example, when the atomizing piece 211 is abnormal or the atomizing piece 211 is disconnected from the boost inductor 212, the voltage at the secondary end of the boost inductor 212 (i.e. the voltage at the first end of the atomizing piece 211) is greater than or equal to an abnormal voltage threshold, for example 200V; when the atomizing piece 211 is working normally, the voltage at the secondary end of the boost inductor 212 (i.e. the voltage at the first end of the atomizing piece 211) is less than or equal to a normal voltage threshold, for example 75V. By connecting the first end of the atomizing piece 211 to the ground through the first voltage dividing resistor Ra and the second voltage dividing resistor Rb in series, and connecting the connection point of the first voltage dividing resistor Ra and the second voltage dividing resistor Rb to the controller 11, the detection voltage detected by the voltage dividing circuit composed of the first voltage dividing resistor Ra and the second voltage dividing resistor Rb can reflect the voltage at the secondary end of the boost inductor 212, thereby reflecting the normal or abnormal state of the atomizing piece 211. In this way, the controller 11 determines whether the state of the atomizing piece 211 is abnormal according to the detection voltage, thereby achieving abnormal detection of the atomizing piece 211.

[0063] In an embodiment, as shown in Figure 6As shown, the first detection module 31 further includes a sampling resistor Rs and a current sensing amplifier circuit 311, the sampling resistor Rs is connected between the primary side of the boost inductor 212 and the second power supply VCC2, the first input end in- of the current sensing amplifier circuit 311 is connected with the first end of the sampling resistor Rs, the second input end in+ of the current sensing amplifier circuit 311 is connected with the second end of the sampling resistor Rs, and the output end out of the current sensing amplifier circuit 311 is connected with the controller 11 through the sixth resistor R6 to provide the voltage difference between the two ends of the sampling resistor Rs to the controller 11; the controller 11 is further configured to control the gate driver 213 to drive the transistor M1 to be cut off to stop the boost inductor 212 from providing the boosted supply voltage to the atomizing piece 211 in the case that the voltage difference is less than a preset first voltage threshold.

[0064] For example, during the process that the atomizing piece 211 atomizes the skin lotion, whether the container containing the skin lotion has the skin lotion or not will cause the average power consumption of the atomizing piece 211 to have a difference, resulting in a significant difference in the supply current of the second power supply VCC2. Specifically, if the container containing the skin lotion has the skin lotion, the supply current of the second power supply VCC2 is larger; if the container containing the skin lotion has no skin lotion, the supply current of the second power supply VCC2 is smaller. Based on this, by arranging the sampling resistor Rs between the primary side of the boost inductor 212 and the second power supply VCC2, the supply current of the second power supply VCC2 can be detected by the sampling resistor Rs, so as to detect whether the container has the skin lotion or not, for example, when the current flowing through the sampling resistor Rs is a first current value, the container has the skin lotion; when the current flowing through the sampling resistor Rs is a second current value, the container has no skin lotion; wherein the first current value is greater than the second current value.

[0065] In addition, by connecting the first input end in- of the current sensing amplifier circuit 311 with the first end of the sampling resistor Rs, connecting the second input end in+ of the current sensing amplifier circuit 311 with the second end of the sampling resistor Rs, and connecting the output end out of the current sensing amplifier circuit 311 with the controller 11 through the sixth resistor R6, the voltage difference between the two ends of the sampling resistor Rs can be determined by the current sensing amplifier circuit 311. Since the voltage difference between the two ends of the sampling resistor Rs is in a positive proportional relationship with the current flowing through the sampling resistor Rs, the voltage difference can be used to reflect whether the container has the skin lotion or not, realizing the detection function of the skin lotion. Furthermore, the controller 11 can determine that the container has no skin lotion in the case that the voltage difference is less than the preset first voltage threshold, and control the gate driver 213 to drive the transistor M1 to be cut off to stop the boost inductor 212 from providing the boosted supply voltage to the atomizing piece 211. In this way, the atomizing piece 211 can be protected in the case that the container has no skin lotion.

[0066] Preferably, please refer toFigure 1 The first detection module 31 further comprises a buzzer (not shown in the drawings) connected to the controller 11, and the controller 11 is further configured to control the buzzer to emit a prompt sound when the voltage difference is less than a preset voltage threshold. In this way, the user can be reminded to supplement the skin care liquid into the container through the prompt sound.

[0067] Optionally, as shown in FIG. 1, Figure 6 In the atomization module 21, the second power supply VCC2 is grounded through the second capacitor C2. In the first detection module 31, one end of the sixth resistor R6 connected to the controller 11 is grounded through the third capacitor C3; and / or, the third power supply VCC3 is grounded through the fourth capacitor C4.

[0068] In an embodiment, as shown in FIG. 1, Figure 1 and Figure 7 The cosmetic device 100 further comprises a second detection module 41, and the second detection module 41 comprises a third driving circuit 411, an infrared emission circuit 412, an infrared receiving circuit 413 and a signal amplification circuit 414.

[0069] The input end of the third driving circuit 411 is connected to the controller 11, the infrared emission circuit 412 and the infrared receiving circuit 413 are both connected to the output end of the third driving circuit 411, the infrared emission circuit 412 is configured to emit infrared light towards the to-be-detected area under the driving of the third driving circuit 411, and the infrared receiving circuit 413 is configured to receive the infrared light reflected by the to-be-detected area and convert it into a voltage signal under the driving of the third driving circuit 411; wherein the wavelength range of the infrared light received by the infrared receiving circuit 413 is greater than or equal to 900 nm, for example, 900 nm, 1000 nm, 1100 nm, 1200 nm.

[0070] The signal amplification circuit 414 is connected between the infrared receiving circuit 413 and the controller 11, and is configured to transmit the voltage signal to the controller 11 after amplification, so that the controller 11 controls the first driving module 12 to stop driving the first light source 14 to emit light and controls the second driving module 13 to stop driving the second light source 15 to emit light when the amplified voltage signal is less than a preset second voltage threshold.

[0071] In actual application, when the user is located in the detection area, the infrared light emitted by the infrared emitting circuit 412 irradiates the user and is reflected to the infrared receiving circuit 413, at this time, the infrared receiving circuit 413 receives relatively strong infrared light, and the voltage signal converted by the infrared receiving circuit 413 is relatively strong; when the user is located outside the detection area, the infrared light emitted by the infrared emitting circuit 412 irradiates the detection area, and may be reflected to the infrared receiving circuit 413 via the external environment such as wall or table, at this time, the infrared receiving circuit 413 receives relatively weak infrared light, and the voltage signal converted by the infrared receiving circuit 413 is relatively weak. In this way, the controller 11 can determine that the user is not located in the detection area when the amplified voltage signal is less than the second voltage threshold, and determine that the user is located in the detection area when the amplified voltage signal is greater than the second voltage threshold; wherein the first voltage threshold is less than the second voltage threshold, so as to realize the controller 11 detecting whether the user is located in the detection area according to the amplified current signal.

[0072] In the process of infrared detection, when the ambient light, the light emitted by the first light source 14 and the visible light emitted by the second light source 15 irradiate the detection area, they are also reflected to the infrared receiving circuit 413, which is easy to interfere with the infrared detection. The above scheme sets the wavelength range of the infrared light received by the infrared receiving circuit 413 to be greater than or equal to 900 nm, so that the sensitivity of the infrared receiving circuit 413 to the infrared light reflected from the detection area is relatively strong, and the sensitivity of the infrared receiving circuit 413 to the remaining visible light is relatively weak, thereby effectively improving the anti-interference of the infrared detection, and solving the problem of low anti-interference of the infrared detection.

[0073] In addition, the controller 11 is configured to control the first driving module 12 to stop driving the first light source 14 to emit light and control the second driving module 13 to stop the second light source 15 from emitting light when the amplified voltage signal is less than the second voltage threshold, so that the first light source 14 and the second light source 15 are automatically controlled to be turned off when it is detected that the user is not located in the detection area, which is beneficial to saving energy.

[0074] In an embodiment, as shown in FIG. 4, the third driving circuit 411 includes a second triode Q2, the infrared emitting circuit 412 includes an infrared emitting LED chip IRD1, and the infrared receiving circuit 413 includes an infrared receiving LED chip IRD2. Figure 7 The base of the second triode Q2 is connected with the first end of a seventh resistor R7, the second end of the seventh resistor R7 constitutes the input end of the third driving circuit 411, the emitter of the second triode Q2 is connected with a third power supply VCC3, and the base of the second triode Q2 is connected with the emitter through an eighth resistor R8, and the collector of the second triode Q2 constitutes the output end of the third driving circuit 411.

[0075] The anode of the infrared emission LED chip IRD1 is connected to the output terminal of the third driving circuit 411 through the ninth resistor R9, and the cathode of the infrared emission LED chip IRD1 is grounded. The cathode of the infrared receiving LED chip IRD2 is connected to the output terminal of the third driving circuit 411, and the anode of the infrared receiving LED chip IRD2 is grounded through the tenth resistor R10. The fifth capacitor C5 is connected in parallel across the tenth resistor R10.

[0076] The signal amplification circuit 414 is connected between the anode of the infrared receiving LED chip IRD2 and the controller 11. The signal amplification circuit 414 can be a same-phase operational amplification circuit.

[0077] Exemplarily, as shown in Figure 7 and Figure 8 the second triode Q2 can be a PNP type triode. When the controller 11 provides a low level to the base of the second triode Q2 through the seventh resistor R7, the collector junction and the emitter junction of the second triode Q2 are both in a forward bias conduction state. The third power supply VCC3 provides a power supply voltage to the anode of the infrared emission LED chip IRD1 through the ninth resistor R9, and provides a power supply voltage to the cathode of the infrared receiving LED chip IRD2, so that the infrared emission LED chip IRD1 emits infrared light towards the to-be-detected area, and the infrared receiving LED chip IRD2 converts the infrared light received via the to-be-detected area into a current signal. Since the infrared receiving LED chip IRD2 is grounded through the tenth resistor R10, the current signal flowing through the tenth resistor R10 generates a voltage division on the tenth resistor R10, so that the voltage division on the tenth resistor R10 is determined by the current signal and equal to the voltage of the anode of the infrared receiving LED chip IRD2. Therefore, the infrared light received by the infrared receiving LED chip IRD2 can be converted into a voltage signal. By connecting the signal amplification circuit 414 between the anode of the infrared receiving LED chip IRD2 and the controller 11, the voltage signal can be provided to the signal amplification circuit 414, so that the voltage signal is transmitted to the controller 11 after being amplified by the signal amplification circuit 414.

[0078] Exemplarily, as shown in Figure 7 and Figure 8As shown, the branch where the infrared emission LED chip IRD1 is located and the branch where the infrared receiving LED chip IRD2 is located can both be multiple, and the branch where the multiple infrared emission LED chips IRD1 are located and the branch where the multiple infrared receiving LED chips IRD2 are located correspond one by one. The signal amplification circuit 414 includes an operational amplifier chip OP with double operational amplifiers. The non-inverting input end in1+ of one of the operational amplifiers in the operational amplifier chip OP is connected with the positive electrode of one infrared receiving LED chip IRD2, the inverting input end in1- is connected with the output end out1 through the eleventh resistor R11 and grounded through the twelfth resistor R12, and the output end out1 is connected with the controller 11. The non-inverting input end in2+ of the other operational amplifier in the operational amplifier chip OP is connected with the positive electrode of the other infrared receiving LED chip IRD2, the inverting input end in2- is connected with the output end out2 through the thirteenth resistor R13 and grounded through the fourteenth resistor R14, and the output end out2 is connected with the controller 11. In this way, the signal amplification circuit 414 can form two non-inverting operational amplification circuits, so that each non-inverting operational amplification circuit transmits the voltage signal amplified by the positive electrode of each infrared receiving LED chip IRD2 to the controller 11.

[0079] In one embodiment, as shown in Figure 1 The cosmetic device 100 further includes at least one of a voice recognition module 51, a temperature detection module 52, a display module 53, a key coding module 54 and a system setting module, and the voice recognition module 51, the temperature detection module 52, the display module 53, the key coding module 54 and the system setting module 55 are respectively connected with the controller 11.

[0080] The voice recognition module 51 is configured to receive and recognize the voice instruction of the user, so as to perform voice interaction with the user, wake up the controller 11 through the voice instruction, control the controller 11 to select the working mode, or control the controller 11 to switch the working mode, etc.

[0081] The temperature detection module 52 is configured to detect the temperature of the controller 11, and when the temperature detection module 52 detects that the temperature of the controller 11 exceeds the preset temperature threshold, the controller 11 controls the display module 53 to perform alarm display.

[0082] The display module 53 is configured to receive and display the state information of the components such as the atomizing piece 211 sent by the controller 11. For example, the display module 53 includes a display screen and a driving chip, the controller 11 is connected with the driving chip through a serial port, the driving chip is connected with the display screen, the controller 11 sends the state information of each component in the cosmetic device 100 to the driving chip through the serial port, and the driving chip drives the display screen to display the state information of each component.

The power key can be pressed for a long time to control the on-off of the beauty device 100, the mute key can be clicked to enter / exit the mute mode, the timing key can be clicked to enter the setting time adjustment, the encoder can be rotated to set the use time of the first light source 14, the second light source 15 or the atomizing piece 211, and the timing key can be clicked to confirm and exit after the time adjustment.
