Description

Technical Field

[0001] The present application relates to the field of household energy beauty, and in particular to a short-wave handheld beauty instrument. Background Art

[0002] Shortwave radiofrequency technology is a method of heating skin tissue by generating a high-frequency electric field. In beauty care, shortwave radiofrequency can promote the production and regeneration of collagen, improve skin elasticity and firmness, reduce fine lines and wrinkles, and improve skin texture. In addition, it can promote blood circulation, accelerate metabolism, and help remove toxins and waste, thereby improving the health and radiance of the skin.

[0003] The RF frequencies commonly used by home beauty devices or handheld beauty devices on the market are currently concentrated between 1MHz and 4.2MHz, among which 1MHz and 2MHz are more common choices, while professional institutions or medical-grade beauty devices mainly use higher frequencies, such as 6.78MHz, 13.56MHz and other RF frequencies. The penetration depth of RF energy is closely related to the frequency, and the penetration depth of RF energy determines the depth to which the RF energy can contact the subcutaneous tissue. Usually, within a safe range, the deeper the penetration of RF energy, the better the beauty effect, which can promote deeper thermal effects, thereby achieving better skin treatment effects. The RF frequency of home beauty devices and handheld beauty devices is much lower than that of medical-grade beauty devices, which limits the beauty effects of home beauty devices and handheld beauty devices.

[0004] Therefore, it is necessary to provide a short-wave handheld beauty instrument that can generate higher radio frequency energy to solve the problem that the existing handheld beauty instruments generate relatively small radio frequency energy, which limits the beauty effect.

[0040] The shortwave handheld beauty device provided above is designed with an adjustment module, which controls the adjustment module to amplify the radio frequency signal generated by the signal source through the control module to obtain radio frequency energy with an intensity reaching the level of medical beauty, thereby solving the problem that the radio frequency energy generated by the existing handheld beauty device is relatively small, which limits the beauty effect.

[0041] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0042] See also Figure 1-Figure 3 The embodiment of the present application provides a shortwave handheld beauty instrument 100, comprising an operation module 1, a signal source 2 connected to the operation module 1, the signal source 2 is used to generate a radio frequency signal, an adjustment module 3 connected to the operation module 1 and the signal source 2 respectively, the operation module 1 controls the adjustment module 3 to receive and amplify the radio frequency signal, and generate a radio frequency with a power set by the operation module 1, a detection module 4 connected to the operation module 1 and the adjustment module 3 respectively, the detection module 4 receives and detects the frequency of the radio frequency generated by the adjustment module 3, and sends the detection result to the operation module 1, and an output module 5 connected to the detection module 4 outputs the detected radio frequency.

[0043] Specifically, the signal source 2 is used to generate a radio frequency signal, provide an input signal for subsequent processing, ensure that the device has a stable radio frequency signal source 2, and ensure the normal operation of the device. The adjustment module 3 receives and amplifies the radio frequency signal, generates a radio frequency signal with a power set by the operation module 1, and amplifies the radio frequency signal to ensure that the signal can reach the power level required by the device, and ensure the performance and effect of the device. The detection module 4 receives the radio frequency signal from the adjustment module 3, which is a radio frequency signal after amplification and power adjustment. The detection module 4 performs frequency detection on the received radio frequency signal. This includes measuring the frequency of the radio frequency signal to determine whether the signal is within the required frequency range. The detection module 4 sends the frequency size of the detected radio frequency signal and related information to the operation module 1. The operation module 1 can further control and adjust the device based on this information. The output module 5 is a radio frequency electrode head, which outputs the radio frequency detected by the detection module 4 to the outside world and contacts the skin, wherein the output module 5 receives the radio frequency signal from the detection module 4, and after the detection of the detection module 4, the stability and accuracy of its frequency are ensured. The output module 5 is responsible for ensuring that the output radio frequency signal is of good quality, that is, the amplitude and frequency of the signal are within the normal range, so as to ensure the effectiveness of subsequent processing and application.

[0044] In a specific example, it also includes:

[0045] The filter 6 is connected to the adjustment module 3 and the detection module 4 respectively. The radio frequency generated by the adjustment module 3 is first transmitted to the filter 6, and the filter 6 filters out the radio frequency with a specific waveform and then transmits it to the detection module 4.

[0046] Specifically, the filter 6 is an electronic device used to selectively allow signals within a specific frequency range to pass through and discard signals of other frequencies. Its main function is to perform frequency screening on the signal to filter out unnecessary frequency components or reduce interference, thereby improving the signal quality of the system. The working principle of the filter 6 is based on its specific circuit design and frequency response characteristics. Usually, the design of the filter 6 will use components such as capacitors, inductors and resistors, and by adjusting the values ​​and connection methods of these components, the response to signals of different frequencies is achieved. The filter 6 is used to perform frequency screening on the input RF signal and only allow signals within a specific frequency range to pass through. It can be a low-pass filter 6, a high-pass filter 6 or a band-pass filter 6, etc. The appropriate type of filter 6 is selected according to the needs.

[0047] In a specific example, it also includes:

[0048] The temperature detection module 74 is data-connected with the operation module 1 . The temperature detection module 74 measures the temperature of the skin around the output module 5 and sends the detected temperature data to the operation module 1 .

[0049] Specifically, the temperature detection module 74 is mainly used to measure the temperature of the skin around the device to monitor the temperature change of the skin during the treatment or beauty treatment. This is usually achieved through a thermistor, which is a component whose resistance value changes with temperature. By measuring the change in resistance, the temperature of the surrounding environment can be inferred. The temperature detection module 74 measures the temperature of the skin around the output module 5 through a thermistor or other detection device, and sends the detected temperature data to the operation module 1 through a data connection. The operation module 1 receives and processes the temperature data, and controls the adjustment module accordingly according to the temperature situation. The control adjustment module adjusts the adjustment amplitude. If the ambient temperature of the output module 5 is high, the operation module 1 controls the adjustment module 3 to reduce the amplitude of the amplified radio frequency. If the temperature around the output module 5 is low, the operation module 1 can control the adjustment module 3 to increase the amplification amplitude of the radio frequency, thereby increasing the energy generated by the radio frequency at the skin to ensure the safety and comfort of the skin during the treatment or beauty treatment.

[0050] Furthermore, the specific steps for the shortwave handheld beauty instrument 100 to self-regulate the radio frequency power are: first, select the required temperature level through the operation module 1, and then the output module 5 detects whether the output module 5 contacts the skin through the corresponding sensor. If so, the signal source 2 starts to output the radio frequency signal to the adjustment module 3, and the radio frequency signal is amplified and detected and then output from the output module 5 to the outside world. Then the temperature detection module 74 detects whether the temperature of the skin around the output module 5 reaches the temperature of the operation module 1 and whether it reaches the preset value, and sends the detected temperature to the operation module 1. If not, the radio frequency signal continues to be output. If the temperature reaches the preset temperature, the operation module 1 controls the signal source 2 to suspend the output power for 10 seconds. After 10 seconds, if the temperature is less than the preset temperature, the operation module 1 controls the signal source 2 to continue to output the radio frequency signal. If ten seconds later, if the temperature is greater than the preset temperature, the operation module 1 continues to control the signal source 2 to suspend the output power for 10 seconds.

[0051] In a specific example, the adjustment module 3 includes an amplifier chip 32 and an input circuit 31 connected to the amplifier chip 32 and the signal source 2 respectively, and an output circuit 33 connected to the detection module 4 and the amplifier chip 32 respectively.

[0052] Specifically, the amplifier chip 32 is the core component of the adjustment module 3, which is responsible for amplifying the radio frequency signal. It may be an integrated circuit specially designed for radio frequency signal amplification, with high frequency response and large gain. The input circuit 31 is connected to the amplifier chip 32 and the signal source 2, and plays the role of introducing the radio frequency signal generated by the signal source 2 into the amplifier chip 32. This input circuit 31 includes a series of components, such as capacitors, inductors, resistors, etc., which are used to match, filter and adjust the signal to ensure that the signal can be effectively transmitted to the amplifier chip 32. The output circuit 33 is connected to the amplifier chip 32 and the detection module 4, and is used to transmit the amplified radio frequency signal to the detection module 4. This output circuit 33 may further process the signal, such as filtering, matching or adjusting, to meet the input requirements of the detection module 4 or improve the signal quality.

It is a negative voltage power supply that provides the required operating voltage for the circuit. -3V3DD ​​refers to a power supply with a voltage of -3.3V. In many radio frequency power amplifier designs, the gate requires a negative bias voltage to ensure that it works at a suitable operating point. The negative bias voltage can help improve the linearity and efficiency of the power amplifier and reduce nonlinear distortion. Usually, -3.3V is a common negative bias voltage value, but the voltage here can also be replaced by -2V or -5V to adapt to various circuit requirements.

[0061] In a specific example, the amplifier chip 32 has four NC pins, and the four NC pins are all grounded.

[0062] Specifically, "NC" stands for "Not Connected", which means that these pins are not connected to any function or component in the circuit design. Therefore, these four NC pins are grounded, which means that they are connected to the ground to ensure that they remain at a stable potential. Usually, NC pins are left vacant in chip design to allow flexible use in different application scenarios. By connecting these pins to the ground, it can be ensured that they will not introduce any interference or unnecessary signals into the circuit. This helps to improve the stability and reliability of the circuit while simplifying the complexity of circuit design and layout.

When the switch is off, the connection between the signal source 2 and the adjustment module 3 is cut off, and the signal cannot be transmitted to the adjustment module 3 through the switch module 8.

[0067] In a specific example, it further includes a voltage conversion module 9 connected to the operating module 1 and the adjusting module 3 , and the voltage conversion module 9 adjusts the external input voltage to the voltage required by the operating module 1 and the adjusting module 3 .

One of the main functions of the voltage conversion module 9 is to adjust the external input voltage. The external input voltage may have different voltage levels or waveforms, and the operation module 1 and the adjustment module 3 may require a specific voltage level to work properly. The voltage conversion module 9 is responsible for adjusting the external input voltage to the voltage level required by the operation module 1 and the adjustment module 3 to ensure their normal operation. The ultimate goal of the voltage conversion module 9 is to ensure that the operation module 1 and the adjustment module 3 can get the voltage supply they need. By adjusting the external input voltage, the voltage conversion module 9 can ensure that the operating module 1 and the adjustment module 3 can obtain stable power under their respective working conditions, thereby ensuring the normal operation and performance of the device.
