[0034] As people's living standards improve, their pursuit of quality of life also increases. Currently, most beauty treatments involve applying skincare products to the skin's surface. However, the chemicals in these products have varying degrees of side effects. Furthermore, unhealthy eating habits, irregular sleep schedules, and late nights contribute to long-term health problems, leading to various skin issues such as dehydration. This has given rise to various beauty treatment devices, among which nano-microcrystals utilize an injection motor to deliver serums directly into the skin.

[0035] However, the injection of these nanocrystals on the market is achieved using a brushed motor, without taking into account the sterilization process of the essence.

[0036] To address the aforementioned problems, this specification provides a system suitable for high-frequency and motor control regulation. For example... Figure 1 As shown, this system is integrated into the beauty device, and the system specifically includes:

[0037] The wireless network communication module is used to establish wireless communication with the user's mobile device. The wireless network communication module is electrically connected to the rotating screen, high-frequency handle, nano-microcrystalline handle and motor drive chip, and is responsible for controlling the operation of the above components.

[0038] Preferably, the wireless network communication module uses the ESP32 series chip.

[0039] A rotating screen is used to display a QR code. In this embodiment, the QR code is generated and transmitted to the rotating screen by a wireless network communication module.

[0040] Preferably, the wireless network communication module establishes communication with the rotating screen mentioned above through a Universal Asynchronous Receiver / Transmitter (UART). UART is an asynchronous serial communication protocol that achieves full-duplex communication through two lines (transmit TX and receive RX) and is widely used in embedded systems, industrial control and other fields.

[0041] A DC-to-AC (AC-DC) module is used to convert input DC power into DC power supply voltage. It mainly converts AC power input (220V / 50Hz) into 12V DC power, which is then used as the 12V power supply voltage. The DC-to-AC module can also convert other forms of AC power into 12V DC power, such as converting 110V / 60Hz AC power into 12V DC power.

[0042] The first DC-DC converter module is used to convert the supply voltage to a first target voltage (9V) and transmit the first target voltage to the high-frequency handle to power the high-frequency handle. A first switch is provided between the first DC-DC converter module and the high-frequency handle, and the first switch is electrically connected to the wireless network communication module, that is, the wireless network communication module is responsible for controlling the on and off of the first switch. The second DC-DC converter module is used to convert the supply voltage to a second target voltage (5V) and transmit the second target voltage to the high-frequency handle, also to power the high-frequency handle.

[0043] It should be noted that both the first and second target voltages power the main control chip (MCU) located inside the high-frequency handpiece, enabling it to start and operate normally. A high-voltage transformer is also installed inside the high-frequency handpiece.

[0044] The high-frequency handpiece can be equipped with a corresponding step-down circuit or step-down component, which converts the first and second target voltages into the working voltage required by the high-frequency handpiece. When the high-frequency handpiece is working, it can use 5kV high voltage to perform ozone disinfection treatment on the essence.

[0045] The first DC-DC isolation module is used to isolate and convert the supply voltage to the first target voltage (9V); the second DC-DC conversion module is used to isolate and convert the supply voltage to the second target voltage (5V). Both DC isolation modules also perform isolation processing during voltage conversion.

[0046] The first step-down module is used to step down the first target voltage to the first operating voltage (5V) in order to power the rotating screen; the second step-down module is used to step down the second target voltage to the second operating voltage (3.3V) in order to power the wireless network communication module.

[0047] In this embodiment, both of the above-mentioned step-down modules use low dropout regulators (LDOs) for voltage reduction. An LDO is a DC step-down linear regulator that can maintain a stable output voltage even when the input voltage or load current changes. By setting up step-down modules, a more stable operating voltage can be provided for the rotating screen and the wireless network communication module.

[0048] The nanocrystalline handle contains a geared motor and a brushless motor. The geared motor is used for dispensing liquid, while the brushless motor is used for injection. By replacing the brushed motor with a brushless motor, it has low noise, long lifespan, and a better user experience.

[0049] A motor drive chip is located between the DC-to-AC module and the geared motor. A second switch is provided between the motor drive chip and the DC-to-AC module, and the second switch is electrically connected to the wireless network communication module.

[0050] The geared motors in both the high-frequency handle and the nano-microcrystalline handle are powered by the same power supply. However, when the high-frequency handle is in operation, the second switch needs to be controlled by the wireless network communication module to cut off the power supply to the geared motor. This is to prevent the high-frequency handle from interfering with the function pins of the geared motor and causing the motor to enter an abnormal working state, thus avoiding affecting the non-working state of the geared motor.

[0051] A third switch is provided between the brushless motor and the DC to AC converter, and the third switch is electrically connected to the wireless network communication module.

[0052] In this embodiment, a first optocoupler is provided between the first switch and the wireless network communication module; a second optocoupler is provided between the second and third switches and the wireless network communication module; a third optocoupler is provided between the motor drive chip and the wireless network communication module; a fourth optocoupler is provided between the brushless motor and the wireless network communication module; a fourth optocoupler is provided between the high-frequency handle and the wireless network communication module; the wireless network communication module outputs one PWM control signal to the brushless motor; and the wireless network communication module outputs two PWM control signals to the motor drive chip.

[0053] Preferably, the high-frequency handle establishes communication with the wireless network communication module via a single bus, and the single bus is equipped with a fifth optocoupler; the geared motor establishes communication with the wireless network communication module to perform angle detection, and this line is equipped with a sixth optocoupler; the brushless motor also establishes communication with the wireless network communication module to trigger the limit switch, and this line is equipped with a seventh optocoupler.

[0054] Therefore, the wireless network communication module can control various external components through each optocoupler, preventing the high-frequency handle, geared motor, and brushless motor from interfering with the normal operation of the wireless network communication module.

[0055] Communication between the wireless network communication module and the high-frequency handle module is controlled by a single bus, which controls the high-frequency setting, power on, and power off. The wireless network communication module controls the liquid-throwing motor using two GPIO pins (50Hz). Based on a truth table, it controls the forward rotation, pause, and reverse rotation of the geared motor. Two limit switches are used to detect whether the liquid-throwing motor is in position, determining whether it reverses and returns to its original position. A vibration sensor detects the handle's tilt angle; if the tilt angle is greater than 10 degrees towards the pin, a circuit is established, and feedback via an optocoupler to the GPIO pin of the wireless network communication module is a high level, thus activating the liquid-throwing motor to prevent leakage into the handle. The brushless motor is also controlled by one PWM (5kHz) pin from the wireless network communication module.

[0056] The voice module is electrically connected to the wireless network communication module, for example, the two communicate via I... 2 Communication is established via the C-bus, and the wireless network communication module directly controls the voice module. The output of the voice module can be electrically connected to audio output devices such as speakers.

[0057] The system works as follows:

[0058] The input AC power is converted to the supply voltage via a DC-to-AC converter. After the system is powered on, the voice module and the wireless network communication module are initialized first. At the same time, both GPIOs of the geared motor output a low level, and one PWM control signal controlling the brushless motor is also low. The MCU inside the high-frequency handle is initialized, and the two PWM input signals output a low level. The rotating screen is also initialized. Then, the wireless network communication module sends some device information and MAC address to the rotating screen via the serial port. The rotating screen generates a QR code based on this information.

[0059] After a user's mobile device, such as a phone or tablet, connects to the internet, they scan a QR code and create an order. The system first checks the server to see if there is any balance left for the order. If so, based on the user's actions, such as controlling the high-frequency handle's speed and starting it, the mobile device sends a command to the wireless network communication module via wireless communication, such as Bluetooth. After receiving the command, the wireless network communication module parses it and then sends a corresponding command to the MCU inside the high-frequency handle. The MCU receives the signal from the single bus and sends an intermittent PWM to drive the high-voltage transformer to generate a 5kV peak voltage. When the high-frequency handle is working, it can use the 5kV high voltage to perform ozone disinfection on the essence. At the same time, it cuts off the power to the two motors and synchronizes the countdown timer to the phone and rotating screen. The user's mobile device then writes the information to the server for storage.

[0060] Similarly, when the system switches to the nanocrystalline function, the 9V power supply to the high-frequency handle is disconnected, and the 12V motor is connected. Based on the user's selection of the push motor and injection motor speeds, the wireless network communication module synchronously controls the corresponding motor speed. Once the geared motor pushes the handle to its maximum position, it triggers the limit switch, connecting the 12V power supply. This voltage is then fed back to the wireless network communication module via an optocoupler. Upon receiving this information, the wireless network communication module stops the brushless motor, and the geared motor begins to reverse at full speed. Once it reaches the bottom and triggers the limit switch again, the wireless network communication module stops the geared motor. Simultaneously, the vibration sensor inside the nanocrystalline handle detects whether the handle is tilted forward or backward. If it is tilted backward, the wireless network communication module detects this and stops the geared motor to prevent liquid leakage into the handle.

[0061] This invention relates to a system for high-frequency and motor control adjustment. By replacing the brushed motor in the existing technology with a brushless motor, the system achieves lower noise, longer lifespan, and a better user experience. The system also incorporates a high-frequency handpiece, which generates high voltage during operation. This high voltage is used to sterilize the serum with ozone, thus combining serum injection and sterilization in one process, enhancing the user experience. The high-frequency handpiece and the nano-microcrystalline handpiece share a single power supply for their geared motors. However, when the high-frequency handpiece is in operation, a wireless network communication module controls a second switch to cut off the power to the geared motor. This prevents the high-frequency handpiece from interfering with the geared motor's functional pins and causing it to enter an abnormal operating state, thus avoiding interference with the geared motor's non-operating state. The wireless network communication module allows users to remotely control the system via mobile devices, providing excellent human-computer interaction. Simultaneously, the system's operating status can be monitored in the backend, facilitating management.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
