[0038] In order to enable those skilled in the art to better understand this solution, the following will clearly describe the technical solutions in the embodiments of this solution with reference to the drawings in the embodiments of this solution. Obviously, the described embodiments are part of the embodiments of this solution, rather than all of them.

In addition, terms such as "first" and "second" are used to distinguish different objects, rather than to describe a specific order.

[0040] The implementation of the present disclosure will be described in detail with reference to the specific drawings as follows:

[0041] Figure 1 It is a schematic structural diagram of a pulse frequency enhancement device provided for an embodiment of the present disclosure. Referring to Figure 1 this, the pulse frequency enhancement device includes a central control module 101, a power supply module 102, a frequency enhancement module 103, a frequency detection module 104, a pulse width adjustment unit 105, and a light source module 106.

[0042] The central control module 101 is connected to the power supply module 102.

[0043] The power supply module 102 is connected to the frequency enhancement module 103.

[0044] The frequency enhancement module 103 is respectively connected to the frequency detection module 104 and the pulse width adjustment unit 105.

[0045] The frequency detection module 104 is connected to the central control module 101.

[0046] The pulse width adjustment unit 105 is connected to the light source module 106.

[0047] In this embodiment, the central control module 101 can receive the feedback signal from the frequency detection module 104, and according to the preset treatment parameters and the pulse frequency information detected in real time, ensure the pulse signal strength by adjusting the output voltage of the power supply module 102.

[0048] In this embodiment, the power supply module 102 provides a stable working voltage for the entire device to ensure that each module can work properly.

[0049] In this embodiment, the frequency enhancement module 103 can increase the pulse signal frequency. It can receive the electrical energy from the power supply module 102 and enhance the frequency of the input pulse signal through the internal circuit structure (such as oscillators, amplifiers, etc.). The enhanced pulse signal can be transmitted to the frequency detection module 104 and the pulse width adjustment unit 105 for further processing. The frequency detection module 104 can monitor the frequency of the pulse signal in real time, convert the frequency of the pulse signal into a voltage signal, and transmit the detection result to the central control module 101. The central control module 101 ensures the pulse signal strength and stability by adjusting the output voltage of the power supply module 102 according to the feedback voltage signal and the preset treatment parameters.

[0050] Exemplarily, the device can be used in an intense pulsed light treatment instrument to perform targeted treatment on skin problems such as acne and skin pigmentation. By adjusting the frequency and pulse width of the pulse signal, precise treatment of the deep layer of the skin can be achieved, improving the treatment effect.

[0051] In this embodiment, the user can enhance the pulse frequency according to needs, meeting the requirements for high-frequency pulses in certain scenarios. Through the combined use of the frequency enhancement module 103 and the frequency detection module 104, the frequency of the pulse can be monitored and adjusted in real time to ensure the frequency stability and accuracy during the treatment process. The application of this pulse frequency enhancement device makes the intense pulsed light treatment instrument more flexible, precise, and stable in the regulation of the pulse frequency. The user can flexibly adjust the pulse frequency or pulse width according to specific situations and needs, better meeting the actual requirements.

[0052] As Figure 2 shown, in an embodiment of the present disclosure, the frequency enhancement module 103 includes a frequency enhancement unit 107 and a signal shaping unit 108.

[0053] The frequency enhancement unit 107 is connected to the signal shaping unit 108.

[0054] The signal shaping unit 108 is respectively connected to the frequency detection module 104 and the pulse width adjustment unit 105.

[0055] In this embodiment, the frequency enhancement unit 107 is configured to increase the frequency of the pulse signal, and the signal shaping unit 108 is configured to shape and optimize the signal to ensure the stability and accuracy of the pulse signal.

[0056] Exemplarily, in dermatological treatment, when using an intense pulsed light treatment instrument to treat the skin, high-frequency and stable pulsed light are required to achieve the best treatment effect. The pulse frequency enhancement device plays an important role in this scenario. The frequency enhancement unit 107 can process the original pulse signal emitted through an internal circuit structure (such as an oscillator, amplifier, etc.) to increase its frequency. The enhanced pulse signal is transmitted to the signal shaping unit 108. The signal shaping unit 108 can shape and filter the signal to eliminate noise and interference in the signal, ensuring the purity and stability of the signal. The shaped signal is respectively transmitted to the frequency detection module 104 and the pulse width adjustment unit 105. The frequency detection module 104 can check and correct the accuracy of the output frequency.

[0057] This embodiment can significantly increase the frequency of the pulse signal, while optimizing the waveform and stability of the signal, thereby improving the treatment effect of the intense pulsed light treatment instrument. In addition, this embodiment can also flexibly adjust the frequency of the signal according to treatment needs to meet the requirements of different treatment scenarios.

[0058] As shown Figure 3 In an embodiment of the present disclosure, the frequency enhancement unit 107 includes: a capacitor C1, a variable resistor RP1, a resistor R1, a unijunction transistor Q1, a resistor R2, a resistor R3, and an amplifier Q2.

[0059] The unijunction transistor Q1 has its first end connected to the first end of the variable resistor RP1, its second end connected to the resistor R1, and its third end connected to the resistor R2 and the resistor R3 respectively.

[0060] The variable resistor RP1 has its first end further connected to the first end of the capacitor C1, and the second end of the capacitor C1 is grounded.

[0061] The variable resistor RP1 has its second end connected to the power supply module 102 and the resistor R1 respectively.

[0062] The amplifier Q2 has its non-inverting input terminal connected to the second end of the resistor R3, its inverting input terminal for receiving a reference voltage, and its output terminal connected to the signal shaping unit 108.

[0063] In this embodiment, the first end of the unijunction transistor Q1 is the emitter, the second end is the first base, and the third end is the second base.

[0064] In this embodiment, the frequency enhancement unit 107 is configured to emit a strong pulse signal and enhance the frequency of the pulse signal. The input signal is introduced through the variable resistor RP1. The first end of RP1 is connected to the capacitor C1, which can filter out high-frequency noise in the input signal and improve the signal stability. By adjusting the resistance value of RP1, the magnitude of the signal input to the unijunction transistor Q1 can be changed. The unijunction transistor Q1 can play a role of non-linear amplification and pulse formation in this circuit. When the input signal enters Q1, Q1 will convert the signal into a pulse signal with a certain shape and frequency according to its internal characteristics. The shape and frequency of this pulse signal can be affected by Q1 and the peripheral resistors R2 and R3. The resistors R2 and R3 are connected to the third end of Q1 to form the load circuit of Q1. The resistance values of these two resistors can affect the amplification factor of Q1 and the frequency of the output pulse signal. By adjusting the resistance values of R2 and R3, the parameters of the output pulse signal can be optimized. The amplifier Q2 can further amplify and optimize the pulse signal generated by Q1. Its non-inverting input terminal is connected to the second end of R3 to receive the pulse signal output by Q1. The inverting input terminal receives a reference voltage for setting the reference level of the output signal. The output signal of Q2 is amplified and adjusted and then sent to the signal shaping unit 108 for further processing.

[0065] This embodiment can significantly increase the frequency of the pulse signal and meet the requirements for high-frequency pulsed light in some special treatments. The synergistic effect of the unijunction transistor Q1 and the amplifier Q2 can optimize the waveform of the output pulse signal, making it more stable, which is beneficial for subsequent signal processing and pulsed light generation.

[0066] As Figure 3 shown, in an embodiment of the present disclosure, the signal shaping unit 108 includes: resistor R4, NOT gate U1, optocoupler D1, power supply VCC, resistor R5, triode Q3, resistor R6, and NOT gate U2.

[0067] The optocoupler D1 has its first end connected to the output end of the NOT gate U1, its second end grounded, its third end connected to both the power supply VCC and the first end of the resistor R5, and its fourth end connected to the first end of the triode Q3.

[0068] The triode Q3 has its second end connected to the second end of the resistor R5, and its third end connected to both the first end of the resistor R6 and the input end of the NOT gate U2. The second end of the resistor R6 is grounded.

[0069] The resistor R4 has its first end connected to the frequency enhancement unit 107 and its second end connected to the input end of the NOT gate U1.

[0070] The output end of the NOT gate U2 is connected to the pulse width adjustment unit 105.

[0071] In this embodiment, the first end of the optocoupler D1 is the positive pole, the second end is the negative pole, the third end is the emitter, and the fourth end is the collector.

[0072] In this embodiment, the resistor R4 serves as a signal input terminal and can receive a signal from the frequency enhancement unit 107. This signal can be a pulse signal that has been preliminarily processed but still requires further shaping. The NOT gate U1 is a logic inverter that logically negates the input signal. If the input is high level, the output is low level, and vice versa. It can convert the input signal into a form suitable for the operation of the optocoupler D1. The optocoupler D1 is an optoelectronic isolation device that can use optical signals to transmit electrical signals and achieve isolation between circuits. The output signal of the NOT gate U1 drives the optocoupler D1. When the NOT gate U1 outputs a low level, the light-emitting diode inside the optocoupler D1 emits light, causing the photosensitive triode to conduct, thereby changing its output state. The output signal of the optocoupler D1 is amplified by the triode Q3. The triode Q3 can be used as an amplifier here, and it amplifies the weak signal output by the optocoupler D1 to a level sufficient to drive the input end of the NOT gate U2. The NOT gate U2 negates the signal again and shapes the signal to eliminate possible noise and interference, ensuring the stability and reliability of the output signal. The shaped signal can be transmitted to the pulse width adjustment unit 105 through the output end of the NOT gate U2 for further processing.

[0073] This embodiment effectively eliminates the noise and interference in the input signal, optimizes the waveform of the signal, and improves the stability and reliability of the signal. The amplification effect of the triode Q3 enhances the driving ability of the signal, ensuring that the signal can drive the subsequent circuit smoothly. The use of the optocoupler D1 realizes the optoelectronic isolation between circuits and enhances the safety and anti-interference ability of the circuit.

[0074] As Figure 3 shown, in an embodiment of the present disclosure, the pulse width adjustment unit 105 includes: a rheostat RP2, a resistor R7, a resistor R8, a capacitor C2, and an amplifier Q4.

[0075] The in-phase input terminal of the amplifier Q4 is respectively connected to the first terminal of the resistor R8 and the first terminal of the rheostat RP2, the anti-phase input terminal is respectively connected to the first terminal of the capacitor C2 and the first terminal of the resistor R7, and the output terminal is connected to the light source module 106.

[0076] The second terminals of the resistor R8 and the capacitor C2 are both grounded.

[0077] The second terminal of the rheostat RP2 is connected to the first terminal of the resistor R7.

[0078] The second terminal of the resistor R7 is connected to the frequency enhancement module 103.

[0079] In this embodiment, the pulse width adjustment unit 105 is configured to adjust the pulse width of the pulse signal generated by the frequency enhancement module 103. The pulse width is the duration of a single pulse in the pulse signal.

[0080] In this embodiment, the rheostat RP2, the resistor R7, and the resistor R8 together constitute a voltage divider circuit. By adjusting the resistance value of the rheostat RP2, the voltage value entering the in-phase input terminal of the amplifier Q4 can be changed. The amplifier Q4 is a differential amplifier. Its in-phase input terminal receives the voltage signal from the voltage divider circuit, and the anti-phase input terminal is connected to the ground through the capacitor C2 to form negative feedback. When the voltage at the in-phase input terminal changes, the amplifier Q4 adjusts the voltage at the output terminal according to its gain characteristic, thereby controlling the pulse width of the pulsed light generated by the light source module 106. The capacitor C2 plays a role of filtering and stabilizing the voltage in the circuit. It can eliminate the high-frequency noise in the input signal and make the input signal of the amplifier Q4 more stable.

[0081] Exemplarily, in dermatological treatment, a doctor uses an intense pulsed light therapy instrument to repair the skin of a patient. Since the skin conditions and treatment depths of different patients are different, the required pulse widths and frequencies of the pulsed light are also different. The doctor can adjust the resistance value of the rheostat RP2 accessed through an external knob to change the pulse width and meet the actual needs of the user. Make the light source module 106 generate pulsed light with an appropriate pulse width, so as to achieve the best treatment effect.

[0082] This embodiment can accurately adjust the pulse width of the pulsed light according to actual needs to meet different treatment requirements.

[0083] In one embodiment of the present disclosure, the frequency detection module 104 includes: a frequency-to-voltage conversion unit.

[0084] In this embodiment, the frequency-to-voltage conversion unit can convert the frequency of the pulse signal into a corresponding voltage value.

[0085] Exemplarily, due to the interference of environmental factors, the power supply VCC is prone to unstable conditions during operation, resulting in unstable pulse intensity. For example, a voltage drop will cause a decrease in the intensity of the output pulse signal. In the frequency-to-voltage conversion unit, a specific circuit (such as a frequency-to-voltage conversion circuit based on LM331) can detect the frequency of the pulse signal and convert the frequency of the pulse signal into a voltage and transmit it to the central control module 101. The central control module 101 can control the power supply module 102 to output the required voltage according to the voltage situation. This ensures the stability and accuracy of the pulse signal intensity.

[0086] Exemplarily, the frequency-to-voltage conversion unit may include a counter or a timer for measuring the number or period of pulse signals within a unit time. Through the measurement of the counter or timer, the frequency of the pulse signal can be converted into a corresponding digital signal. These digital signals can be converted into analog voltage signals through an internal digital-to-analog converter and output. The converted voltage signal can represent the frequency of the original pulse signal. For example, when the pulse signal frequency is higher than the first frequency threshold, a voltage value is output, and when the frequency is lower than the first frequency threshold, the output voltage is 0.

[0087] This embodiment can detect whether the frequency of the output pulse signal matches the target frequency by converting the output pulse frequency into a voltage, correct the deviation part, enhance the stability and accuracy of the pulse frequency, and ensure the intensity of the pulse signal.

[0088] As Figure 2 shown, in one embodiment of the present disclosure, a pulsed frequency enhancement device further includes: a filter module 109.

[0089] The filter module 109 is connected to the light source module 106.

[0090] In this embodiment, the light source module 106 can emit optical pulse signals, and these optical pulse signals can include multiple wavelengths and frequencies. The filter module 109 can include filter elements, such as filter films and interference filters. The filter module 109 can selectively pass or block optical pulses of specific wavelengths or frequency ranges through the filter film and the interference filter.

[0091] This embodiment can filter out optical pulse signals that do not meet the requirements, reduce system noise and interference, and ensure that the wavelength and frequency of the output optical pulse match the treatment target. For example, in some skin treatment applications, optical pulses of a specific wavelength can act more effectively on the target tissue while reducing damage to surrounding tissues. This helps to improve the stability and reliability of the entire pulse frequency enhancement device.

[0092] As Figure 2 shown, in one embodiment of the present disclosure, a pulse frequency enhancement device further includes: a communication module 110.

[0093] The communication module 110 is connected to the central control module 101.

[0094] In this embodiment, the central control module 101 is configured to receive control instructions or data transmission requests from the communication module 110. According to the received instructions, the central control module 101 can coordinate the power module 102 and the frequency detection module 104 to perform corresponding operations. The communication module 110 is configured to communicate with external devices or systems, and can receive and send data or control signals. Through wired or wireless means, the communication module 110 can exchange data with other medical devices, computers, or mobile devices to achieve remote monitoring, control, or data transmission.

[0095] Exemplarily, when the communication module 110 receives an external instruction or data, it will transmit it to the central control module 101, and the central control module 101 adjusts the parameters of the frequency enhancement module 103 or controls the working state of the power module 102 according to the content of the instruction or data.

[0096] This embodiment can achieve remote monitoring and control. Users can remotely view the status of the therapeutic instrument, adjust parameters, or perform other operations through a computer or mobile device, improving the convenience and flexibility of treatment. In addition, the communication module 110 supports real-time transmission and sharing of data, and can transmit the working state, treatment data, etc. of the therapeutic instrument to a remote server or data center in real time, which helps doctors or researchers to conduct a more in-depth analysis and research on the treatment process and provide a basis for the optimization and improvement of treatment plans.

[0097] The above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them; although the present disclosure has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present disclosure.
