Description

Technical Field

[0001] This utility model relates to the field of beauty equipment technology, and in particular to a beauty device. Background Technology

[0002] Existing photon aesthetic devices use light of specific wavelengths to treat skin and remove hair, such as photon beauty devices and photon hair removal devices. However, this specific light is harmful to the eyes, so the output must be pointed directly at the skin. To prevent light leakage, skin detection is usually required to prevent light from emanating from the output when it is not in contact with the skin.

[0003] In some existing technologies, skin detection is achieved by setting a sensing segment at the light outlet and using a capacitive sensing chip to detect the change in capacitance of the sensing segment. However, this approach is prone to false triggering. For example, when only one side of the light outlet is in contact with the skin, light emission may be triggered, resulting in light leakage.

[0004] Meanwhile, the principle behind microcurrent beauty devices is to simulate the body's natural bio-currents through low-level currents. These gentle electrical waves penetrate the skin and tissues, directly acting on facial muscles. This current stimulation promotes blood and lymphatic circulation, enhances cell activity, and thus accelerates collagen production. Existing beauty devices lack the combined functionality of skin detection and microcurrent beauty treatments.

[0005] Therefore, we need a beauty device that can effectively solve the problem of accidental skin detection and also has microcurrent beauty functions. Utility Model Content

[0039] The following will refer to the appendix in the embodiments of this utility model. Figures 1-8 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0040] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure).

[0042] A beauty device is a machine that adjusts according to the body's physiological functions to improve the condition of the body and facial skin. Among them, the photon beauty device uses broadband special wavelength intense pulsed light technology to treat vascular and pigmented lesions, while removing wrinkles and improving the overall condition of the skin.

[0043] However, given the potential harm of this specific wavelength of light to the eyes, ensuring safe use is paramount. To prevent light leakage from causing eye damage, the device typically requires skin detection to ensure that the light outlet is in close contact with the skin before emitting light.

[0044] Current photon beauty devices on the market often face the problem of accidental activation during skin detection, which may lead to unintentional light leakage and pose a threat to the user's eyes. Furthermore, most devices have not yet integrated microcurrent beauty functions, limiting their overall beauty effects.

[0045] Please see Figures 1 to 8 This utility model proposes a beauty device aimed at solving the problems of false triggering in skin detection and the inability to simultaneously integrate microcurrent beauty functions and skin detection functions. For example... Figure 1 As shown, it includes:

[0046] Power supply circuit 01 has a first power supply terminal for outputting a first voltage;

[0047] The device body 08 has a light outlet, and a first electrode plate 81 and a second electrode plate 82 are respectively arranged on both sides of the light outlet. The first electrode plate 81 and the second electrode plate 82 are electrically connected to the first power supply terminal. When the light outlet contacts the skin, the first electrode plate 81, the second electrode plate 82 and the first power supply terminal form a first circuit through the skin.

[0048] The microcurrent circuit 02 is electrically connected to the first electrode plate 81 and the second electrode plate 82 respectively, and is used to output the first microcurrent through the first electrode plate 81 and the second electrode plate 82.

[0049] The current detection circuit is electrically connected to one of the first electrode plate 81 and the second electrode plate 82, and is used to detect the current in the first circuit and output a current detection signal.

[0050] More specifically, the power supply circuit 01 supplies power to the first electrode plate 81 and the second electrode plate 82, and the first electrode plate 81, the second electrode plate 82 and the first power supply terminal form a first circuit through the skin. When the first electrode plate 81 and the second electrode plate 82 are in contact with the skin at the same time, the current flows from the power supply circuit 01 to one of the electrode plates, and then through the skin and the other electrode plate back into the power supply circuit 01.

[0051] Because the first electrode plate 81 and the second electrode plate 82 are respectively located on both sides of the light emission port, when the first electrode plate 81 and the second electrode plate 82 simultaneously contact the skin, the space between them (i.e., the location of the light emission port) will naturally align with the skin. By simply detecting whether a current forms the first circuit through the current detection circuit, it can be determined whether the light emission port is in contact with the skin, thus avoiding accidental contact.

[0052] Meanwhile, this design incorporates a microcurrent circuit 02 to generate a microcurrent. This microcurrent enters the human body through the first electrode 81 and the second electrode 82, stimulating blood and lymphatic circulation and enhancing cell activity. Notably, both the microcurrent circuit 02 and the first circuit utilize the first electrode 81 and the electrode pads. The electrode pads in this design can both detect skin contact and transmit microcurrents to the human body, enhancing the functionality and ease of use of the beauty device while also saving costs.

[0053] This utility model proposes a beauty device that integrates skin sensing detection and microcurrent beauty functions. It uses a current detection circuit to monitor whether the two electrode pads form a current loop with the skin. Light is emitted only when the skin is in contact with both electrode pads at the same time, which effectively avoids false triggering of skin detection. At the same time, this application is equipped with a microcurrent circuit 02, and the microcurrent stimulation can promote blood and lymphatic circulation.

[0054] The electrode pad of this invention can not only form a current loop with the skin to realize the skin sensing function, but also transmit the microcurrent of the microcurrent circuit 02 to the human body, realizing the multiple uses of the electrode pad.

[0055] In one embodiment, the current detection circuit includes an amplifier circuit 03; the amplifier circuit 03 is used to detect the current and amplify it to output a current detection signal.

[0056] The basic principle of the current detection circuit is to measure the current in the circuit and convert it into a processable electrical signal. In this embodiment, the current detection circuit includes an amplifier circuit 03, which detects the current in the first loop and amplifies it to output a current detection signal in order to determine whether the first loop has been formed, thereby determining whether the first electrode plate 81 and the second electrode plate 82 are in contact with the skin at the same time.

[0057] In one embodiment, the amplifier circuit 03 is an operational amplifier detection circuit 31 or a switching transistor amplifier circuit 32, used to detect the current and amplify it to output a current detection signal.

[0058] like Figure 2 As shown, amplifier circuit 03 is an operational amplifier detection circuit 31, which includes operational amplifier U11. The first loop is connected to the input terminal of operational amplifier U11, and the output terminal of operational amplifier U11 outputs an amplified current detection signal. Preferably, operational amplifier U11 is an LM321 operational amplifier. The LM321 is a general-purpose single-channel operational amplifier with internal compensation and a true differential input stage, which is suitable for this embodiment.

[0059] like Figure 3 As shown, amplifier circuit 03 is a switching transistor amplifier circuit 32, which includes a switching transistor Q12. The first electrode plate 811 is electrically connected to a first voltage through resistor R41. The second electrode plate 82 is connected to the base of switching transistor Q12 through resistor R76. The collector of switching transistor Q12 is connected to the first voltage through resistor R79. The emitter of switching transistor Q12 outputs the signal through resistor R47. The amplified current detection signal is sent to the main control circuit 04.

[0060] When the first electrode 81 and the second electrode 82 come into contact with the skin, the skin is a conductor, and the first electrode 81, the second electrode 82, the resistor R76, the collector and base of the switching transistor Q12 form a circuit. Then, the circuit current is amplified by the current amplification principle of the switching transistor, and the amplified current detection signal is output to the main control circuit 04 through the resistor R47.

[0061] Preferably, the second electrode plate 82 is grounded through diode D1, which is used for overvoltage protection; the base of the switching transistor Q12 is grounded through resistor R77, which is used to adjust the output current of the amplifier circuit 03; the emitter of the switching transistor Q12 is grounded through resistor R84, which is used for current shunting.

[0062] In one embodiment, the microcurrent circuit 02 includes a boost circuit 21 and a steering circuit 22. The output terminal of the boost circuit 21 is electrically connected to the steering circuit 22, and the output terminal of the steering circuit 22 is electrically connected to the first electrode plate 81 and the second electrode plate 82.

[0063] like Figure 4As shown, the boost circuit 21 is used to generate and adjust the micro-current voltage according to the received control signal; the steering circuit 22 is used to generate a micro-current and switch the current direction of the output micro-current according to the received control signal.

[0064] More specifically, the boost circuit 21 includes a boost chip U10 and a digital potentiometer chip U2 electrically connected. The boost chip U10 receives a first voltage at its input terminal and outputs a micro-current voltage EMS-VCC. The digital potentiometer chip U2 communicates with the main control circuit 04 via an IIC interface, and adjusts the magnitude of the EMS-VCC voltage output by the boost chip U10 according to the received control signal.

[0065] When the digital potentiometer chip U2 receives a control signal, it adjusts its internal resistance value according to the signal's instructions. This change in resistance alters the voltage division ratio at the output of the boost chip U10, thus affecting the voltage of EMS-VCC. Because the adjustment of the digital potentiometer chip U2 is digital, very precise and repeatable voltage regulation can be achieved. This allows the boost circuit 21 to flexibly adjust the output voltage according to different application scenarios and requirements.

[0066] like Figure 5 As shown, the steering circuit 22 includes switching transistors Q8, Q9, Q10 and Q11, wherein switching transistors Q8 and Q9 are N-type transistors, and switching transistors Q10 and Q11 are P-type transistors.

[0067] The EMS-VCC output of the boost chip U10 is electrically connected to the emitters of switching transistors Q10 and Q11, respectively. The emitter of switching transistor Q11 is electrically connected to the collector of switching transistor Q9, and the emitter of switching transistor Q10 is electrically connected to the collector of switching transistor Q8. The emitters of switching transistors Q8 and Q9 are grounded through resistors. The bases of the above four switching transistors are electrically connected to the output I / O ports of the main control circuit 04. A micro current EMS1 is output through a resistor at the connection between the emitter of switching transistor Q11 and the collector of switching transistor Q9, and a micro current EMS2 is output through a resistor at the connection between the emitter of switching transistor Q10 and the collector of switching transistor Q8.

[0068] According to the control signal from the main control circuit 04, the steering circuit 22 controls the four switching transistors to switch the current direction between EMS1 and EMS2. When the base of switching transistor Q8 and the base of switching transistor Q10 are both low, Q8 is turned off and Q10 is turned on, and current flows out of EMS1. At the same time, when the base of switching transistor Q9 and the base of switching transistor Q11 are both high, Q9 is turned on and Q11 is turned off, and current flows into EMS2. Conversely, current flows from EMS2 to EMS1.

[0069] In one embodiment, the system further includes a main control circuit 04, used to respond to the current detection signal from the current detection circuit and output a control signal to the microcurrent circuit 02. In this embodiment, the main control circuit 04 receives current information from the current detection circuit and determines whether the skin is in simultaneous contact with the first electrode plate 81 and the second electrode plate 82 based on the current information.

[0070] Meanwhile, the main control circuit 04 can also control the micro-current circuit 02 to open or close, or output a micro-current with a corresponding waveform according to the control signal.

[0071] Furthermore, if other circuits are added in this embodiment, they can also be electrically connected to the main control circuit 04, and the main control circuit 04 can respond to received information, make logical judgments and decisions, and issue instructions to realize the intelligence of the circuit.

[0072] The main control circuit 04 includes a microcontroller, preferably an HT66F3195 SSOP28, which has an analog input port and an IIC interface. The analog input port allows the microcontroller to receive continuous analog signals (such as voltage or current signals output from sensors for temperature, pressure, sound, etc.) and convert them into digital signals for processing. When an analog signal enters the microcontroller through the analog input port, the microcontroller's internal analog-to-digital converter (ADC) converts the analog signal into a digital signal.

[0073] The IIC interface is a serial communication protocol used to connect microcontrollers and their peripheral devices (such as EEPROM, ADC, DAC, etc.). It uses two lines (SDA data line and SCL clock line) for communication and has advantages such as simple structure, convenient connection, and moderate communication speed.

[0074] The IIC interface enables bidirectional data transmission via the SDA data line and the SCL clock line. During communication, the master device controls the level changes of the clock line to generate a clock signal and sends or receives data via the data line. The slave device (such as an EEPROM) then performs corresponding operations based on the clock signal and the data on the data lines.

[0075] In one embodiment, the switching circuit 05 has its input terminal electrically connected to the microcurrent circuit 02 and the first power supply terminal via the amplification circuit 03; its output terminal is electrically connected to the first electrode plate 81 and the second electrode plate 82; and its control terminal is electrically connected to the main control circuit 04.

[0076] The switching circuit 05 is used to switch the electrical connection between the first electrode plate 81 and the second electrode plate 82 and the amplifier circuit 03 or the microcurrent circuit 02 according to the control signal received from the main control circuit 04. Through the switching circuit 05, the electrode plates can achieve multiplexing of two functional modules.

[0077] In one embodiment, such as Figure 6 As shown, the switching circuit 05 is a relay switching circuit, which is used to switch the first electrode plate 81 and the second electrode plate 82 electrically connected to the amplifier circuit 03 or the microcurrent circuit 02 through the relay according to the control signal received from the main control circuit 04.

[0078] The relay switching circuit includes a double-pole double-throw relay SW1, a double-pole double-throw relay SW4, a MOSFET Q4, and a MOSFET Q16. Pins 1 and 8 of SW1 and SW4 are coil control terminals used to receive control signals. When the coil terminals receive sufficient voltage or current, the relay will generate a magnetic field and trigger contact switching.

[0079] The first voltage is connected to pin 1 of SW1 and pin 1 of SW4 through resistors respectively. The gates of MOSFET Q4 and MOSFET Q16 are connected to the main control circuit 04 respectively. The sources of MOSFET Q4 and MOSFET Q16 are grounded. The drain of MOSFET Q4 is connected to pin 8 of SW4 and connected to pin 1 of SW4 through a diode. The drain of MOSFET Q16 is connected to pin 8 of SW1 and connected to pin 1 of SW1 through a diode.

[0080] Pins 6 and 3 of SW1 and SW4 are common terminals. These two pins serve as common connection points in the circuit, used to connect common parts of two different circuits. During relay switching, these two common terminals will remain connected to their respective circuit paths.

[0081] Pin 3 of SW1 is electrically connected to pin 4 of SW4, and pin 6 of SW1 is electrically connected to pin 5 of SW4; pin 6 of SW4 is electrically connected to the first electrode plate 81, and pin 3 of SW4 is electrically connected to the second electrode plate 82.

[0082] Pins 7 and 2 of SW1 and SW4 are normally closed terminals, which are closed when the relay is not energized, i.e., connected to their respective common terminals. When the relay receives a control signal and is energized, the normally closed terminals will disconnect from the common terminals.

[0083] The current detection circuit is electrically connected to pin 2 of SW1, and pin 7 of SW1 is electrically connected to the first voltage through a resistor.

[0084] Pins 5 and 4 of SW1 and SW4 are normally open terminals. These normally open terminals are in an open state when the relays are not energized, meaning they are not connected to their respective common terminals. When the relays receive a control signal and are energized, the normally open terminals will connect to the common terminals. The signals EMS1 and EMS2 output from the microcurrent circuit 02 are electrically connected to pins 4 and 5 of SW1, respectively.

[0085] When the gate of MOSFET Q4 is high and the gate of MOSFET Q16 is high, MOSFET Q4 is turned on, the relay is energized, and pins 3 and 4 of SW4 are connected, and pins 6 and 5 of SW4 are connected. When MOSFET Q16 is turned on, the relay is energized, and pins 3 and 4 of SW1 are connected, and pins 6 and 5 of SW1 are connected. Thus, the first electrode 81 is electrically connected to EMS2 through SW1 and SW4, and the second electrode 82 is electrically connected to EMS1 through SW1 and SW4. The electrode plates realize the microcurrent beauty function.

[0086] When the gate of MOSFET Q4 is high and the gate of MOSFET Q16 is either high or low, MOSFET Q4 is turned on, the relay is energized, and pins 3 and 4 of SW4 are connected, and pins 6 and 5 are connected. When MOSFET Q16 is not turned on, the relay is not energized, and pins 3 and 2 of SW1 are connected, and pins 6 and 7 are connected. Thus, the first electrode 81 is electrically connected to the first voltage through SW1 and SW4, and the second electrode 82 is electrically connected to the current detection circuit through SW1 and SW4. The electrodes realize the skin sensing function.

[0087] In one embodiment, it further includes: a phototherapy circuit 06, which is electrically connected to the main control circuit 04; the phototherapy circuit 06 is used to turn the light source on or off according to the control signal received from the main control circuit 04.

[0088] like Figure 7 As shown, the phototherapy circuit 06 includes a tungsten filament lamp, a voltage regulation chip U100, a MOSFET Q3, and a digital potentiometer chip U6. The MOSFET Q3 is used to receive control signals from the main control circuit 04 and output them to the enable pin of the voltage regulation chip U100. The digital potentiometer chip U6 is connected to the main control circuit 04 through the IIC interface to adjust the voltage OUT of the tungsten filament lamp output by the voltage regulation chip U100.

[0089] In one embodiment, the power supply circuit 01 includes a power input circuit, a first conversion circuit, and a second conversion circuit. The output terminal of the power input circuit is electrically connected to the input terminal of the first conversion circuit, and the output terminal of the first conversion circuit is electrically connected to the input terminal of the second conversion circuit.

[0090] A power input circuit for connecting to an external power source, and having a third power supply terminal for outputting a third voltage;

[0091] The first conversion circuit is used to convert the third voltage into a first voltage output, and has a first power supply terminal for outputting the first voltage;

[0092] The second conversion circuit is used to convert the first voltage into a second voltage output, and has a second power supply terminal for outputting the second voltage.

[0093] More specifically, in this embodiment, the third voltage is the input voltage, which is stepped down to the first voltage by the first conversion circuit, and then the first voltage is stepped down to the second voltage by the second conversion circuit, which respectively power the remaining circuits in the beauty device.

[0094] In one embodiment, such as Figure 5 As shown, a light-transmitting lens 83 covers the light outlet, and a first electrode plate 81 and a second electrode plate 82 are respectively disposed on opposite sides of the light-transmitting lens 83. The light-transmitting lens 83, the first electrode plate 81 and the second electrode plate 82 are respectively embedded on the surface of the main body 08 of the device.

[0095] The light-transmitting lens 83 covers the light outlet. The light source emitted by the tungsten filament lamp in the phototherapy circuit 06 needs to contact the skin through the light-transmitting lens 83. In this embodiment, the first electrode plate 81 and the second electrode plate 82 simultaneously contact the skin and form a first circuit, which allows the main control circuit 04 to detect and determine that the light-transmitting lens 83 is in contact with and aligned with the skin. Only then is the tungsten filament lamp allowed to turn on the light source. This can better avoid accidental contact or light leakage and effectively ensure human safety.

[0096] The photon beauty device also includes control button circuits, acceleration sensor circuits, temperature sensor circuits, vibration motor circuits, buzzer circuits, indicator light board circuits, etc.

[0097] The control button circuit serves as the interface for users to interact with the photon beauty device. By pressing different buttons, users can select different working modes, adjust parameters, or perform other operations. The button circuit typically includes a button switch and corresponding signal processing circuitry. When a button is pressed, it changes the resistance or capacitance value in the circuit, thereby triggering the signal processing circuit to generate a corresponding signal. These signals are then transmitted to the main control circuit 04 for processing to achieve the desired function.

[0098] The accelerometer circuit is used to detect changes in acceleration during the operation of the photon beauty device, such as movement speed and vibration. The accelerometer typically contains a piezoelectric element or a micro-mechanical system (MEMS) structure, which generates an electrical signal when subjected to external force. These electrical signals are amplified and filtered before being transmitted to the main control circuit 04 for further analysis and processing.

[0099] The temperature sensor circuit monitors the temperature of the internal or external environment of the photon beauty device to ensure that the device operates within a suitable temperature range. The temperature sensor converts temperature changes into electrical signals. These electrical signals are amplified and converted before being transmitted to the main control circuit 04 for display or to control other circuit modules.

[0100] A vibration motor circuit is used to drive a vibration motor to produce a vibration effect, providing tactile feedback or achieving other functions. Vibration motors typically operate on the principle of electromagnetic induction; when current passes through a coil, a magnetic field is generated, which interacts with a permanent magnet inside the motor to produce rotational or vibrational force. The vibration motor circuit is responsible for providing a stable current and voltage to ensure the motor functions properly.

[0101] A buzzer circuit is used to generate sound signals to provide functions such as audible alerts, alarms, or music playback. Buzzers typically consist of sound-generating elements such as piezoelectric ceramic discs or electromagnetic coils. When current flows through the sound-generating element, it vibrates and produces sound. The buzzer circuit controls the on / off state and frequency of the current to generate the desired sound signal.

[0102] The indicator light panel circuitry displays the operating status, battery level, and fault information of the photon beauty device. The indicator light panel typically contains multiple LEDs or other light-emitting elements, each corresponding to a specific status or information. The indicator light panel circuitry controls the on / off state and flashing frequency of these light-emitting elements to display the necessary information to the user.
