Description

Technical Field

[0001] The utility model relates to the technical field of beauty equipment, and in particular to an output power adaptive control circuit of beauty equipment. Background Art

[0002] Intense pulsed light is a high-power, wide-spectrum non-continuous light source. When intense pulsed light is irradiated on the skin, it will produce photobiochemical and thermal decomposition effects on the skin. Intense pulsed light therapy devices that use this principle can effectively promote the regeneration of skin collagen, restore skin elasticity, and eliminate or reduce wrinkles.

[0003] With the development of intense pulsed light (IPL) light sources and control technology, as well as the growing demand for beauty, a number of home-use IPL devices have emerged in recent years for lightening spots and removing melanin.

[0004] Because IPL devices are high-power beauty devices, improper use can cause skin burns. Existing IPL devices typically operate in open-loop control, with output fixed to a set power level, posing a risk of burns. Utility Model Content

[0051] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0053] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0054] In response to the problem in related technologies that beauty devices have a fixed output according to the set power, which poses a risk of burning the user's skin, in an embodiment of the present application, an adaptive output power control circuit is provided. This circuit can obtain information through the connection between the main control chip and the temperature detection module, the voltage and current detection module, and the touch detection module, and thus adaptively adjust the output power according to the system voltage, current, and skin temperature. This can not only fully meet the user's therapeutic needs, but also ensure the safety of the beauty device during use.

[0055] The following is an introduction to the technical solutions provided in the embodiments of the present application.

[0056] Combined with reference Figure 1 An embodiment of the present application provides an output power adaptive control circuit for a beauty device. The output power adaptive control circuit includes: a main control chip 10, an intense pulsed light driving module 20, a temperature detection module 30, a voltage and current detection module 40, and a touch detection module 50. The main control chip 10 adopts a microcontroller.

[0057] Among them, the intense pulsed light driving module 20 is connected to the PC2 pin of the main control chip 10, and the intense pulsed light driving module 20 is used to drive and control the lighting of the xenon lamp; the temperature detection module 30 is connected to at least the PD3, PB1, and PB2 pins of the main control chip 10, and the temperature detection module 30 is used to sense temperature; the voltage and current detection module 40 is connected to the PB4 and PB5 pins of the main control chip 10, and the voltage and current detection module 40 is used to detect peak voltage and peak current; the touch detection module 50 is connected to at least the PC4, PC5, and PC6 pins of the main control chip, and the touch detection module 50 is used to detect contact with the skin.

[0058] Current IPL cosmetic devices generally operate in an open-loop mode, with a fixed power output based on the user's selected power level. However, because IPL cosmetic devices are high-power electronic devices with high energy output, improper use can cause skin burns, while lower energy outputs may not achieve the desired therapeutic effect. Therefore, in the present embodiment, while ensuring clinical therapeutic efficacy, an adaptive output power control circuit is designed. This circuit, through a temperature detection module 30, a voltage and current detection module 40, and a touch detection module 50, each connected to the main control chip 10, can detect skin temperature, the system's peak voltage and current, and the presence of skin contact in real time, dynamically adjusting the output power of the IPL driver module 20 accordingly. This achieves both clinical efficacy and product safety.

[0059] The intense pulsed light driving module 20 can drive and control the lighting of the xenon lamp: the high-voltage trigger coil gives the lamp an instantaneous ultra-high voltage to turn on the lamp, and then gives a low voltage to maintain the conduction of the lamp, thereby lighting the xenon lamp.

[0060] In one possible implementation, the temperature detection module 30 includes three temperature sensing points, each temperature sensing point includes a first resistor and a first capacitor; the first end of the first resistor is connected to the VDD pin of the main control chip, the second end of the first resistor is connected to the first end of the first capacitor and a pin of the main control chip, and the second end of the first capacitor is grounded.

[0061] Specifically, such as Figure 2As shown, one temperature sensing point includes a resistor R8 and a capacitor C8, the first end of the resistor R8 can be connected to the VDD pin of the main control chip, the second end of the resistor R8 can be connected to the first end of the capacitor C8 and a PD3 pin of the main control chip, and the second end of the capacitor C8 is grounded; another temperature sensing point includes: a resistor R9 and a capacitor C9, the first end of the resistor R9 can be connected to the VDD pin of the main control chip, the second end of the resistor R9 can be connected to the first end of the capacitor C9 and a PB1 pin of the main control chip, and the second end of the capacitor C9 is grounded; another temperature sensing point includes: a resistor R10 and a capacitor C10, the first end of the resistor R10 can be connected to the VDD pin of the main control chip, the second end of the resistor R10 can be connected to the first end of the capacitor C10 and a PB2 pin of the main control chip, and the second end of the capacitor C10 is grounded. By placing three thermistor (Negative Temperature Coefficient, NTC) temperature-sensing points on the contact head, the main control chip 10 collects the temperature of the temperature-sensing points in real time through three ADCs and uses a curve fitting method to obtain the temperature of the center point of the skin. When the temperature of the center point of the skin is too high, it will trigger an interrupt response from the main control chip 10 and reduce the corresponding output power of the intense pulsed light driver module. When the temperature of the center point of the skin drops, in order to ensure the quality effect, the main control chip 10 will adaptively increase the corresponding output power of the intense pulsed light driver module to increase the light output energy.

[0062] In one possible implementation, Figure 3 As shown, the touch detection module 50 includes three touch sensing sub-modules (marked as U7, U8, and U9 in the figure), each of which includes a touch sensing chip. The touch sensing chip adopts a single-button capacitive sensing device; the OUT pin of the touch sensing chip is connected to the corresponding pin of the main control chip.

[0063] Specifically, such as Figure 3 As shown, the touch detection module 50 uses a three-way touch sensing chip (IC / AI01H-SOT23-6) to sense whether the contact head is in contact with the skin. Only when it is sensed that the contact head is in contact with the skin will the pulse light driving module be allowed to emit light, thereby avoiding the intensity of the strong pulse light from damaging the eyes; the touch chip uses two single-button capacitive sensing devices with the function of automatic sensitivity correction. The chip has a common-mode interference removal circuit and a built-in button debounce. After the chip's sensing antenna KEY pin detects a touch, the OUT pin outputs a low level. This pin is connected to the interrupt IO interface of the main control chip, which will trigger an interrupt to prompt that the sensing contact head is touched, and the main control chip will make corresponding control operations.

[0064] Furthermore, each touch sensing sub-module also includes: a second resistor, a first end of which is connected to the VDD pin of the touch sensing chip, and a second end is connected to the VDD pin of the main control chip; a third resistor, a first end of which is connected to the VDD pin of the touch sensing chip, and a second end is connected to a line pin of the main control chip; a fourth resistor, a first end of which is connected to the KEY pin of the touch sensing chip, and a second end is connected to the contact head; a second capacitor, a first end of which is connected to the VDD pin of the touch sensing chip, and a second end is connected to ground; a third capacitor, a first end of which is connected to the C1 pin of the touch sensing chip, and a second end is connected to ground; and a fourth capacitor, a first end of which is connected to the CSEL pin of the touch sensing chip, and a second end is connected to ground.

[0065] Specifically, such as Figure 3 As shown, for the touch sensing submodule U7, the first end of resistor R1 is connected to the VDD pin of the touch sensing chip, and the second end is connected to the VDD pin of the main control chip; the first end of resistor R2 is connected to the VDD pin of the touch sensing chip, and the second end is connected to the PC5 pin of the main control chip; the first end of resistor R7 is connected to the KEY pin of the touch sensing chip, and the second end is connected to the contact head; the first end of capacitor C6 is connected to the VDD pin of the touch sensing chip, and the second end is grounded; the first end of capacitor C3 is connected to the C1 pin of the touch sensing chip, and the second end is grounded; the first end of capacitor C5 is connected to the CSEL pin of the touch sensing chip, and the second end is grounded. In one possible implementation, as Figure 1 As shown, the output power adaptive control circuit also includes: a power management module 60; the power management module 60 includes: a boost submodule and a buck submodule; the input end of the boost submodule is the initial power supply voltage, and the output end is connected to the intense pulse light driving module 20; the input end of the buck submodule is the initial power supply voltage, and the output end is connected to the VDD pin of the main control chip.

[0066] Specifically, the power management module is divided into two parts: Figure 4 The boost submodule shown, and Figure 5 The step-down submodule shown; the entire output power adaptive control circuit is powered by a 12V / 24V DC adapter, and the voltage is increased to 300V DC through the boost module for driving the intense pulsed light driver module 20; the voltage is reduced to 5V through the step-down module for powering the main control chip 10 and other peripheral devices.

[0067] In one possible implementation, Figure 1As shown, the output power adaptive control circuit also includes: a human-computer interaction module 70; the human-computer interaction module 70 includes a gear adjustment submodule and an indicator light submodule, the gear adjustment submodule is used to adjust the gear of the output power, and the indicator light submodule is used to indicate the current power output status; the gear adjustment submodule is connected to the PB7 pin of the main control chip 10 through a first switch; the indicator light submodule is connected to the PD4 pin of the main control chip 10 through a second switch.

[0068] Specifically, such as Figure 6 As shown, the human-computer interaction module 70 includes two parts: a gear adjustment submodule and an indicator light submodule. It is composed of two key circuits (marked as SW2 and SW1 in the figure), which correspond to the power on / off / gear adjustment and light output buttons respectively; the indicator light is composed of three three-color lights, which correspond to three gears indicating the current power output status, for example: red represents standby state, yellow represents reduced power output, and green represents normal output.

[0069] Furthermore, the first pin, the third pin, and the fourth pin of the first switch are grounded, and the second pin is connected to the PB7 pin of the main control chip, the first end of the fifth capacitor, and the first end of the first diode respectively; the second ends of the fifth capacitor and the first diode are grounded. Figure 6 As shown, the first pin, the third pin, and the fourth pin of the switch SW2 are grounded, and the second pin is respectively connected to the PB7 pin of the main control chip 10, the first end of the capacitor C2, and the first end of the diode D1; the second ends of the capacitor C2 and the diode D1 are grounded.

[0072] Specifically, the buzzer driver module 80 outputs pulse width modulation (PWM) waves with different duty cycles through the IO port of the main control chip to drive the buzzer to emit different sounds, which indicate different working states through different sounds, such as power on / off state, high temperature alarm, voltage and current overload alarm, etc. The specific circuit of the buzzer driver module 80 can be as follows Figure 7 shown.

[0073] In one possible implementation, Figure 1 As shown, the output power adaptive control circuit further includes: a fan driving module 90, which is used to drive the fan to rotate; the fan driving module 90 is connected to the PB3 and PC3 pins of the main control chip respectively.

[0074] Specifically, the fan driver module 90 is used to drive the fan to rotate and monitor the working status of the fan in real time through an ADC of the main control chip. When the fan is abnormal, it will trigger an interrupt response of the main control chip, thereby protecting the device from further damage. The specific circuit of the fan driver module 90 can be as follows: Figure 8 shown.

[0075] Among them, the main control chip can adopt an 8-bit microcontroller with a maximum main frequency of 16MHz, 8kB on-chip Flash, and peripheral interfaces including UART, SPI, I2C, 10-bit ADC, etc. The main control chip is connected to each module through IO pins and interacts with the corresponding module through specific interfaces to control or monitor the working status of each module. For example, the microcontroller can be a model of STM8S003K3T6CTR. Specifically, the specific circuit of the main control chip 10 can be as follows Figure 9 shown.
