[0035] The embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0036] It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a central component at the same time. When a component is considered to be "located on" another component, it may be directly located on the other component or there may be a central component at the same time.

[0037] An embodiment of the present application provides a skin intelligent contact sensing system, which is applied to a radio frequency beauty instrument and includes a control unit, a transmitting module, a signal amplifying module and a detection unit. The control unit is connected to an external power supply and performs voltage conversion. The transmitting module is connected to the control unit and emits a radio frequency signal. The signal amplifying module is connected to the transmitting module and receives the radio frequency signal. The received radio frequency signal is amplified by the signal amplifying module to generate radio frequency energy, and the radio frequency energy is transmitted to the human skin; the detection unit is connected to the control unit, and the detection unit is connected to the signal amplifying module. The detection unit detects the peak voltage of the radio frequency energy output signal at each moment. When the radio frequency beauty instrument leaves the human skin, the peak voltage at the moment before leaving is recorded as U1, and the peak voltage at the moment after leaving is recorded as U2. The radio frequency energy output at the moment before leaving is recorded as P1, and the radio frequency energy at the moment after leaving is recorded as P2, and the relationship is satisfied:

[0038] U2>U1;

[0039] P1>P2.

[0040] The above-mentioned intelligent skin contact sensing system converts the power supply voltage into low voltage and high voltage modes through a control unit, and according to the peak voltage of the output signal of the signal amplification module monitored by the detection unit, the control unit converts the low voltage mode or high voltage mode to release high-power or low-power radio frequency energy.

[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 6 The embodiment of the present application provides a skin intelligent contact sensing system 100, which is applied to a radio frequency beauty instrument 200. The skin intelligent sensing system includes a control unit 10, a transmitting module 20, a signal amplification module 30 and a detection unit 40. The control unit 10 is connected to an external power supply 11 and performs voltage conversion. The transmitting module 20 is connected to the control unit 10 and sends a radio frequency signal 21. The signal amplification module 30 is connected to the transmitting module 20 and receives the radio frequency signal 21. The received radio frequency signal 21 is amplified to generate radio frequency energy 34 under the action of the signal amplification module 30, and the radio frequency energy 34 is transmitted to the human skin 300; the detection unit 40 is connected to the control unit 10, and the detection unit 40 is connected to the signal amplification module 30. The detection unit 40 detects the peak voltage of the radio frequency energy 34 output signal at each moment. When the radio frequency beauty instrument 200 leaves the human skin 300, the peak voltage at the moment before leaving is recorded as U1, and the peak voltage at the moment after leaving is recorded as U2. The radio frequency energy 34 output at the moment before leaving is recorded as P1, and the radio frequency energy 34 at the moment after leaving is recorded as P2, and the relationship is satisfied:

[0043] U2>U1;

[0044] P1>P2.

[0045] Specifically, the control unit 10 provides a stable power supply and converts the voltage of the external power supply 11 into an operating voltage suitable for the radio frequency beauty instrument 200 in both the state of contacting the skin and the state of not contacting the skin, so as to ensure the normal operation of the device.

[0046] Furthermore, the transmitting module 20 is responsible for generating the radio frequency signal 21, which is the basis for the radio frequency beauty instrument 200 to release the radio frequency energy 34. The signal amplification module 30 plays a key role, which receives the radio frequency signal 21 from the transmitting module 20 and amplifies it to generate enough radio frequency energy 34 to achieve the beauty effect. And different powers of radio frequency energy 34 are achieved according to different working voltages.

[0047] Furthermore, the detection unit 40 can detect in real time whether the radio frequency beauty instrument 200 has left the human skin 300 by monitoring the peak voltage of the radio frequency energy 34 output signal, and automatically adjust the working voltage of the device in time according to the detection result by connecting with the control unit 10.

[0048] Furthermore, when the RF beauty instrument 200 is in contact with the human skin 300, the detection unit 40 will continuously monitor the peak voltage of the RF energy 34 output signal and ensure that it is within the set range. At this time, the control unit 10 switches the circuit to the high voltage module 10111, so that the RF energy 34 is high-power RF energy 34 released to the skin surface to achieve a beauty effect; when the RF beauty instrument 200 leaves the human skin 300, the detection unit 40 will detect that the peak voltage of the RF energy 34 output signal increases rapidly and exceeds the specified range. At this time, the control unit 10 switches the circuit to the low voltage module 10112, so that the RF energy 34 is low-power RF energy 34 released to the skin surface to achieve a beauty effect.

[0049] Furthermore, the peak voltage before leaving is recorded as U1, and is the peak voltage of the beauty instrument touching the skin. The peak voltage after leaving is recorded as U2, and is the peak voltage of the beauty instrument leaving the skin. The peak voltage of the beauty instrument leaving the skin is greater than the peak voltage of the beauty instrument touching the skin, satisfying the relationship:

[0050] U2>U1;

[0051] The peak voltage changes when the beauty instrument contacts or leaves the skin, through the probe part of the beauty instrument, which contains a sensing resistor and a voltage regulator. When the probe of the beauty instrument contacts the skin, the sensing resistor is connected in parallel with the skin, causing the total resistance to drop. The voltage regulator detects the change in resistance and increases the output voltage to keep the current constant or achieve a predetermined treatment effect; on the contrary, when the probe of the beauty instrument leaves the skin, the sensing resistor is no longer connected in parallel with the skin, and the total resistance increases. The voltage regulator detects the change in resistance and reduces the output voltage to prevent unnecessary energy release or ensure user safety. In this way, the beauty instrument is able to generate different peak voltages when contacting and leaving the skin.

[0052] In summary, the RF energy 34 outputted at the moment before leaving is recorded as P1, and the RF energy 34 outputted when the beauty device contacts the skin. The RF energy 34 outputted at the moment after leaving is recorded as P2, and the RF energy 34 outputted when the beauty device leaves the skin. The RF energy 34 outputted when the beauty device contacts the skin is greater than the RF energy 34 outputted when the beauty device leaves the skin, satisfying the relationship:

[0053] P1>P2.

[0054] In a specific implementation example, the detection unit 40 includes a receiving module 41 and a comparing module 42. The receiving module 41 is connected to the signal amplifying module 30 and generates first data 411 including the peak voltage of the output signal at each moment; the comparing module 42 includes second data 421 including the peak voltage of a fixed range, the comparing module 42 is connected to the receiving module 41 and receives the first data 411, and the comparing module 42 compares the first data 411 with the second data 421 and generates comparison information 4142.

[0055] Specifically, the receiving module 41 is connected to the signal amplifying module 30, and generates the first data 411 including the peak voltage of the output signal at each moment. The main function of the receiving module 41 is to monitor the peak voltage of the output signal of the RF energy 34, that is, to detect the voltage level of the output signal of the RF energy 34 at each moment, and convert it into digital data for subsequent processing and analysis.

[0056] Furthermore, the fixed range peak voltage is input to the comparison module 42 to form the second data 421, and is connected to the receiving module 41. The comparison module 42 receives the first data 411 generated by the receiving module 41, that is, the peak voltage data of the output signal at each moment, and compares it with the fixed range peak voltage second data 421. Through comparison and analysis, it is determined whether the radio frequency beauty instrument 200 is in the skin contact state, thereby controlling the release of the radio frequency energy 34.

[0057] Furthermore, the receiving module 41 continuously monitors the peak voltage of the output signal of the RF energy 34 at each moment and converts it into digital data. The comparing module 42 receives the first data 411 generated by the receiving module 41 and compares it with the peak voltage second data 421 of a fixed range.

[0058] Furthermore, if the first data 411 and the second data 421 are within a fixed range, it is determined that the RF beauty device 200 is in the correct skin contact state and releases high-power RF energy 34; if the first data 411 exceeds the fixed range, it is determined that the RF beauty device 200 has left the skin and stops releasing low-power RF energy 34 to increase the service life of the beauty device.

[0059] In a specific implementation example, the detection unit 40 also includes a judgment module 43, which is connected to the comparison module 42 and receives comparison information 4142, and generates a first feedback module 431 at a moment before the radio frequency beauty device 200 leaves the human skin 300 and a second feedback module 432 at a moment after the radio frequency beauty device 200 leaves the human skin 300.

[0060] Specifically, the judgment module 43 is connected to the comparison module 42 and receives the comparison information 4142, which is used to judge whether the radio frequency beauty instrument 200 leaves or contacts the human skin 300, and generate a corresponding feedback module. The judgment module 43 receives the comparison information 4142 generated by the comparison module 42, which indicates whether the radio frequency beauty instrument 200 leaves or contacts the human skin 300.

[0061] Further, according to the received comparison information 4142 , the judgment module 43 generates a first feedback module 431 that the radio frequency beauty device 200 contacts the human skin 300 and a second feedback module 432 that the radio frequency beauty device 200 leaves the human skin 300 .

[0062] Furthermore, the judgment module 43 can be applied to various radio frequency beauty devices 200, especially when it needs to contact the skin and release radio frequency energy 34. Through the feedback module generated by the judgment module 43, an intelligent sensing system can be realized to protect the user's skin safety and improve the user's experience.

[0063] Furthermore, the first feedback module 431 and the second feedback module 432 are feedback modules generated according to the comparison information 4142, and are used to indicate the contact status between the radio frequency beauty instrument 200 and the skin. According to the judgment result of the judgment module 43, the first feedback module 431 and the second feedback module 432 respectively generate status feedback of the radio frequency beauty instrument 200 contacting the human skin 300 and leaving the human skin 300. These feedback modules may include signals or indicator lights, etc., to prompt the user of the use status of the radio frequency beauty instrument 200.

[0064] In a specific implementation example, the first data 411 is recorded as A1, the second data 421 is recorded as A2, and the comparison information 4142 included in the first feedback module 431 satisfies the relationship:

[0065] A1∈A2;

[0066] The comparison information 4142 included in the second feedback module 432 satisfies the relationship:

[0067]

[0068] Specifically, A1 represents a fixed peak voltage range, and A2 represents a peak voltage monitored in real time by the monitoring unit. A1 and A2 in the judgment module are compared to determine the contact condition between the beauty instrument and the human skin 300 , so that the control unit 10 controls the change of the radio frequency energy 34 .

[0069] Further, first, the judgment module obtains the peak voltages A1 and A2 before and after leaving the human skin 300. A1 and A2 are compared, where if A1∈A2, it can be represented as the radio frequency energy 34 is in contact with the human skin 300, and the contrast information 4142 is generated and transmitted to the first feedback module 431. The first feedback module 431 is connected to the high voltage module 10111 in the control unit 10, so that the system circuit is in a high voltage state and outputs high-power radio frequency energy 34; and if This may indicate that the RF energy 34 output has lost contact with the skin, generating contrast information 4142, which is transmitted to the second feedback module 432. The second feedback module 432 is connected to the low voltage module 10112 in the control unit 10, so that the system circuit is in a low voltage state and outputs low-power RF energy 34.

[0070] In a specific implementation example, the detection unit 40 also includes a transmission module 44, one end of which is connected to the first feedback module 431 and the second feedback module 432 respectively to obtain comparison information 4142, and the other end is connected to the control unit 10 to receive comparison information 4142.

[0071] Specifically, the transmission module 44 is used to transmit the comparison information 4142 contained in the first feedback module 431 and the second feedback module 432, and transmit the information to the control unit 10. The contact state between the radio frequency beauty instrument 200 and the skin and the output of the radio frequency energy 34 are monitored in real time, and corresponding control measures are taken according to the feedback information to ensure the safety and effectiveness of the device.

[0072] Furthermore, one end of the transmission module 44 is connected to the first feedback module 431 and the second feedback module 432, and is used to obtain the comparison information 4142 contained in these modules. The other end of the transmission module 44 is connected to the control unit 10, and is used to feed back the obtained comparison information 4142 to the control unit 10. Through this connection and transmission process, the transmission module 44 enables the control unit 10 to obtain feedback information about the working status of the device in real time, so as to take corresponding control measures.

[0073] Furthermore, in the actual application of the radio frequency beauty instrument 200, the transmission module 44 can transmit feedback information about the contact state between the device and the skin and the output of the radio frequency energy 34 to the control unit 10. The control unit 10 can adjust the output of the radio frequency energy 34 in a timely manner according to the received feedback information to adapt to different skin types and different treatment needs, thereby ensuring the safety and effectiveness of the treatment.

[0074] Furthermore, when the sensor detects that the RF beauty device 200 has lost contact with the skin, the control unit 10 can automatically reduce the output of the RF energy 34 to avoid unnecessary damage to the beauty device. When the sensor detects that the output of the RF energy 34 is abnormal, the control unit 10 can also take timely measures, such as adjusting the energy output level or issuing an alarm to alert the operator.

[0075] In a specific implementation example, the control unit 10 is connected to an external power supply 11 and converts voltage to generate a voltage module 1011, the voltage module 1011 includes a high voltage module 10111, the high voltage module 10111 is connected to one end of the transmission module 44, the other end of the transmission module 44 is connected to the first feedback module 431 and feeds back the comparison information 4142 contained in the first feedback module 431 to the high voltage module 10111 to provide high voltage power supply.

[0076] Specifically, the control unit 10 is the core of the entire skin intelligent contact sensing system 100, responsible for connection with the external power supply 11 and voltage conversion. The voltage module 1011 is managed by the control unit 10, including modules with different voltage outputs. The high voltage module 10111 is a component of the voltage module 1011, responsible for providing high voltage power supply. The transmission module 44 is in the detection unit 40, responsible for transmitting the comparison information 4142. The first feedback module 431 is generated based on the result of the comparison module 42, representing the state of the radio frequency beauty instrument 200 before leaving the skin, that is, the state of the beauty instrument contacting the skin.

[0077] Furthermore, the control unit 10 is responsible for converting the voltage of the external power supply 11 into a voltage suitable for the internal operation of the system. The high voltage module 10111 provides the system with the required high voltage to meet the energy requirements of the radio frequency beauty instrument 200 in a specific operation mode. The transmission module 44 transmits the comparison information 4142 in the first feedback module 431 to the high voltage module 10111. The high voltage module 10111 dynamically adjusts the high voltage output according to the received comparison information 4142 to meet the energy requirements of the radio frequency beauty instrument 200 in different contact states.

[0078] Furthermore, the system can dynamically adjust the voltage output according to the contact state between the radio frequency beauty instrument 200 and the skin, which increases the flexibility of the system. By dynamically adjusting the voltage, the system can reduce potential safety risks while ensuring the treatment effect. The real-time feedback mechanism enables the system to respond quickly to changes and improves the overall operating efficiency.

[0079] Furthermore, the control unit 10 is connected to the external power supply 11, and converts the voltage of the external power supply 11 into a voltage suitable for the internal operation of the system. When the radio frequency beauty instrument 200 contacts the skin, the detection unit 40 starts to work and generates the first data 411 containing the peak voltage of the output signal at each moment. The comparison module 42 compares the first data 411 with the second data 421 of the preset fixed range peak voltage, and generates the comparison information 4142 that the first data 411 is within the range of the second data 421. The judgment module 43 receives the comparison information 4142 and generates the first feedback module 431 of the radio frequency beauty instrument 200 before leaving the skin. The transmission module 44 transmits the comparison information 4142 in the first feedback module 431 to the high voltage module 10111. The high voltage module 10111 dynamically adjusts the high voltage output according to the received comparison information 4142 to meet the energy demand of the radio frequency beauty instrument 200 before leaving the skin.

[0080] In summary, by adjusting the voltage in real time, the system can ensure that sufficient energy is provided when the radio frequency beauty instrument 200 is in contact with the skin, and reduce the energy output when it leaves the skin, thereby improving the efficiency of energy conversion and use. At the same time, when the radio frequency beauty instrument 200 is not in good contact with the skin or is completely away from the skin, the system can reduce the output voltage in time to avoid unnecessary energy release, thereby protecting the user from accidental injury.

[0081] In a specific implementation example, the voltage module 1011 includes a low voltage module 10112, which is connected to one end of the transmission module 44, and the other end of the transmission module 44 is connected to the second feedback module 432 and feeds back the comparison information 4142 contained in the second feedback module 432 to the low voltage module 10112 to provide low voltage power supply.

[0082] Specifically, the voltage module 1011 is the part of the control unit 10 responsible for voltage management, and provides different levels of voltage according to system requirements. The low voltage module 10112 is a component of the voltage module 1011, which is specifically responsible for providing low voltage power supply. The transmission module 44 is responsible for transmitting data or information within the system, specifically referring to transmitting the comparison information 4142 from the detection unit 40 to the control unit 10.

[0083] Furthermore, the second feedback module 432 represents the state of the radio frequency beauty device 200 at a moment after leaving the skin, that is, the radio frequency beauty device 200 leaving the skin state, and includes comparison information 4142 that the first data 411 is not within the range of the second data 421 .

[0084] Furthermore, the low voltage module 10112 provides the system with the required low voltage to meet the energy demand of the radio frequency beauty instrument 200 in a specific operation mode (such as non-contact state). The transmission module 44 transmits the comparison information 4142 in the second feedback module 432 to the low voltage module 10112. This information reflects the change in the contact state between the radio frequency beauty instrument 200 and the skin.

[0085] Furthermore, the low voltage module 10112 dynamically adjusts the low voltage it outputs according to the received comparison information 4142 to adapt to the working requirements of the radio frequency beauty instrument 200 immediately after leaving the skin.

[0086] In summary, when the RF beauty instrument 200 leaves the human skin 300, the detection unit 40 starts working, and the receiving module 41 generates the second data 421 containing the peak voltage of the RF energy 34 output signal at the moment after leaving. The comparison module 42 compares the second data 421 with the first data 411 of the preset fixed range peak voltage to generate comparison information 4142. Then, the judgment module 43 receives the comparison information 4142 and generates a second feedback module 432 at a moment after the RF beauty instrument 200 leaves the skin. The transmission module 44 transmits the comparison information 4142 in the second feedback module 432 to the low voltage module 10112. The low voltage module 10112 dynamically adjusts the low voltage output according to the received comparison information 4142 to meet the energy demand of the RF beauty instrument 200 at a moment after leaving the skin.

[0087] In a specific implementation example, the signal amplification module 30 includes a high-frequency module 31, which is connected to the high-voltage module 10111 and to the transmission signal to generate a high-frequency RF signal 21 and amplify it into RF energy 34 output at the previous moment of leaving.

[0088] Specifically, the signal amplification module 30 is a core component of the skin intelligent contact sensing system 100 , and is responsible for receiving the radio frequency signal 21 and amplifying it to generate radio frequency energy 34 suitable for human skin 300 .

[0089] Furthermore, the high frequency module 31 is a key component of the signal amplification module 30, which is specifically responsible for processing high frequency signals. The high voltage module 10111 is the part of the control unit 10 responsible for providing high voltage power supply, and is connected to the high frequency module 31. The radio frequency signal 21 emitted by the transmitting module 20 is the original signal for generating radio frequency energy 34.

[0090] Furthermore, the core function of the high frequency module 31 is to receive the radio frequency signal 21 sent by the transmitting module 20 and convert it into a high frequency radio frequency signal 21. High frequency signals are usually used for deep skin treatment in the beauty field because they can better penetrate the surface layer of the skin.

[0091] Furthermore, the high-frequency module 31 amplifies the generated high-frequency radio frequency signal 21 to generate sufficient energy to act on the human skin 300. The amplified radio frequency energy 34 is the radio frequency energy 34 output at the previous moment, that is, when the radio frequency beauty instrument 200 contacts the skin, the high-frequency module 31 ensures that the output is sufficiently powerful radio frequency energy 34.

[0092] In summary, the high voltage module 10111 provides high voltage power supply, and the transmitting module 20 sends out the radio frequency signal 21. The high frequency module 31 receives the radio frequency signal 21 and converts it into high power energy. The high frequency module 31 amplifies the high frequency radio frequency signal 21 to generate the radio frequency energy 34 output at the last moment of leaving. The amplified radio frequency energy 34 is transmitted to the human skin 300 through the output module 33 to achieve a cosmetic effect.

[0093] In a specific implementation example, the signal amplification module 30 also includes a low-frequency module 32, which is connected to the low-voltage module 10112 and to the transmission signal to generate a low-frequency signal and amplify it into radio frequency energy 34 at the next moment of leaving.

[0094] Specifically, the signal amplification module 30 is the core part of the skin intelligent contact sensing system 100, which is responsible for receiving and amplifying the radio frequency signal 21 to generate the radio frequency energy 34 required for treatment. The low frequency module 32 is a key component in the signal amplification module 30, which is specifically responsible for processing the low frequency signal. The low voltage module 10112 is a part of the control unit 10, which is responsible for providing low voltage power to the low frequency module 32.

[0095] Furthermore, when the radio frequency beauty instrument 200 is separated from the skin and still working, the control unit 10 switches to low voltage power supply, and the low frequency module 32 receives the radio frequency signal 21 from the transmission signal and converts it into a low frequency signal. The low frequency module 32 generates low-power radio frequency energy 34 from the generated low frequency signal.

[0096] In a specific implementation example, the signal amplification module 30 also includes an output module 33, which is connected to the high-frequency module 31 and generates a first output signal 331 of the radio frequency energy 34 output to the human skin 300 at a moment before the output leaves, and the output module 33 is connected to the low-frequency module 32 and generates a second output signal 332 of the radio frequency energy 34 output to the human skin 300 at a moment after the output leaves.

[0097] Specifically, the output module 33 is a key component of the signal amplification module 30 , and is responsible for transmitting the amplified radio frequency energy 34 to the human skin 300 .

[0098] Furthermore, the first output signal 331 is generated by the high frequency module 31 and corresponds to the RF energy 34 outputted at the previous moment. The second output signal 332 is generated by the low frequency module 32 and corresponds to the RF energy 34 outputted at the next moment.

[0099] Furthermore, the control unit 10 is powered by a high voltage, and after the high frequency module 31 receives the radio frequency signal 21, it amplifies and generates high frequency radio frequency energy 34. The output module 33 is connected to the high frequency module 31, receives the amplified high frequency radio frequency energy 34, and generates a first output signal 331. The first output signal 331 transmits the radio frequency energy 34 output at the last moment to the human skin 300.

[0100] Furthermore, the control unit 10 is powered by a low voltage, and after receiving the radio frequency signal 21, the low frequency module 32 generates low frequency radio frequency energy 34 and generates a second output signal 332. The second output signal 332 transmits the radio frequency energy 34 outputted at a moment after leaving to the beauty instrument.

[0101] In this way, the skin intelligent contact sensing system 100 provided above converts the power supply voltage into low voltage and high voltage modes through the control unit 10, and according to the peak voltage of the output signal of the signal amplification module 30 monitored by the detection unit 40, the control unit 10 converts the low voltage mode or high voltage mode to release high-power or low-power radio frequency energy 34.

[0102] The above is only an implementation method of the present application. It should be pointed out that a person skilled in the art can make improvements without departing from the inventive concept of the present application, but these improvements are within the scope of protection of the present application.
