Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In consideration of the problem that the existing radio frequency beauty equipment is poor in safety and beauty effect and causes poor user feeling, the embodiment of the invention provides a radio frequency signal output system and cell activation equipment; the technology can be applied to equipment for beautifying and shaping based on the radio frequency principle; the techniques may be implemented in associated software or hardware, as described by way of example below.
Referring to fig. 1, a schematic structural diagram of a radio frequency signal output system is shown; the system is applied to radio frequency cosmetic equipment and comprises a signal source module 10, a control module 11 and a power driving module 12; the signal source module 10 includes a plurality of signal generating units; the signal source module 10 and the control module 11 are respectively connected with the power driving module 12;
the signal source module 10 is configured to output multiple radio frequency signals, and each signal generating unit outputs a radio frequency signal corresponding to a phase angle; the control module 11 is configured to receive a working parameter of an external host, and generate a PWM (Pulse Width Modulation) control signal corresponding to each rf signal according to the working parameter; the power driving module 12 is configured to adjust the output intensity of each rf signal according to the PWM control signal, and output each adjusted rf signal, so as to output an rf signal combination in an output mode corresponding to the working parameter.
The signal source module may include a multi-channel signal generating unit to output multi-channel radio frequency signals; the included angle between the phase angles of the radio frequency signals output by every two adjacent signal generating units is 360/n; wherein n is the number of the signal generating units, and n is a positive integer. E.g., three, four, five, etc.; each path of radio frequency signal has the same output frequency and amplitude but different phases; taking three paths of radio frequency signals as an example, the three paths of radio frequency signals can be combined into a radio frequency signal combination with stable variation rule of signal intensity; due to different phases, when the three paths of radio-frequency signals are output simultaneously, the signal intensities of three output points can generate round circulation and fluctuation with a certain rule, and further vortex motion feeling of the outlet water flow is simulated; by adjusting the amplitude or the phase of each path of radio frequency signal, the intensity change rule of the finally output radio frequency signal can be adjusted, and besides the vortex output, the combination of various output modes and output modes such as wave output, continuous output and intermittent output can be realized, so that the somatosensory requirements of different users are met.
According to the radio frequency signal output system provided by the embodiment of the invention, a signal source module outputs a plurality of paths of radio frequency signals, and each signal generation unit outputs a radio frequency signal corresponding to a phase angle; generating a PWM control signal corresponding to each path of radio frequency signal through a control module; the power driving module is used for adjusting the output intensity of each path of radio frequency signal according to the PWM control signal and outputting each path of radio frequency signal after adjustment so as to output the radio frequency signal combination of the output mode corresponding to the working parameter. This mode is through the radio frequency signal of a plurality of signal generation unit output multichannel different phases, need not too high output and can realize better treatment, and the reliability that has improved equipment and user's body feel comfort level are better, have reached the unity of user comfort level and treatment.
The embodiment of the invention also provides another radio frequency signal output system; referring to fig. 2, a schematic structural diagram of a signal source module in another rf signal output system is shown; in the system, a signal source module comprises three paths of signal generating units; the three-way signal generating unit comprises a first signal generating unit 20, a second signal generating unit 21 and a third signal generating unit 22;
the phase angle of the radio frequency signal output by each path of signal generating unit may be: 0 degrees, 120 degrees, and 240 degrees. A schematic diagram of a three-way radio frequency signal waveform as shown in fig. 3; the three paths of radio frequency signals are respectively an A phase, a B phase and a C phase; the phase angle of the a-phase signal may be set to 0 degrees, and the phase angles of the B-phase and C-phase may be set to 120 degrees and 240 degrees, respectively. As can be seen from fig. 3, since the phase angles of the three-phase signals are different, the signal intensities of the signals are different at the same time, and when the three-phase signals are applied to the skin, the user feels that the signal intensities of the three contact points are more than one volt, like the water flow whirls, thereby avoiding the physical discomfort caused by the long-term high-intensity signals on the same skin.
The signal source module further includes an active crystal unit 24 and a reference source buffer 25 connected to each other; the active crystal unit 24 is configured to generate a reference rf signal, and the reference source buffer 25 is configured to buffer and output the reference rf signal.

For example, if the frequency of the square wave signal generated by the active crystal oscillator is 12MHz, and a reference radio frequency signal with the frequency of 3MHz needs to be obtained, the frequency dividing circuit may be a four-frequency dividing circuit; the peak-to-peak value of the square wave signal generated by the active crystal oscillator is typically 5V.
In practical implementation, the source crystal oscillator includes a crystal oscillator circuit and a signal adjusting circuit; the crystal oscillator circuit is used for generating an initial radio frequency signal, and the signal adjusting circuit is used for adjusting the initial radio frequency signal into a square wave signal. Specifically, the signal adjusting circuit comprises a shaping circuit, an inverting circuit, a dead zone adjusting circuit and a gate control circuit which are connected in sequence;
the shaping circuit is used for shaping an initial radio frequency signal into a radio frequency signal in a square wave form; the reverse circuit is used for steering the radio frequency signal in the square wave form; the dead zone adjusting circuit is used for delaying the reversed radio frequency signal; the gate control circuit is used for adjusting the output width of the radio frequency signal. The shaping circuit can comprise a divider resistor and a voltage comparator; after the radio frequency signal is input and is subjected to voltage division by the voltage dividing resistor, the radio frequency signal is input into the voltage comparator, and a comparison result output by the voltage comparator is a radio frequency signal in a square wave form.
The reverse circuit can be realized by a CMOS phase inverter, wherein the CMOS phase inverter comprises two enhanced MOS field effect transistors, specifically, one is an NMOS transistor and can also be called as a driving transistor; the other is a PMOS tube, which can also be a load tube. The gate-source turn-on voltage UTN of the NMOS tube is a positive value, the gate-source turn-on voltage of the PMOS tube is a negative value, and the numerical range is 2-5V. In order to make the circuit work normally, the power supply voltage UDD > (UTN + | UTP |) is required. The UDD can work between 3V and 18V, and the application range is wide. The dead zone adjusting circuit delays the radio-frequency signal to a certain degree, so that the radio-frequency signal is more stable.
Further, the first signal generating unit includes a first signal output interface 201; the first signal output interface 201 is connected to the reference source buffer, and is configured to output a reference radio frequency signal; the second signal generating unit comprises a first delay circuit 211 and a second signal output interface 212 which are connected with each other; the first delay circuit 211 is connected to the reference source buffer, and is configured to delay the reference radio frequency signal, and the second signal output interface 212 is configured to output the delayed radio frequency signal; the third signal generating unit includes a second delay circuit 221 and a third signal output interface 222 connected to each other; the second delay circuit 221 is connected to the reference source buffer, and is configured to delay the reference rf signal, and the third signal output interface 222 is configured to output the delayed rf signal.
In practical implementation, if the second signal generating unit needs to output a radio frequency signal with a phase angle of 120 degrees with respect to a reference radio frequency signal, the delay time of the first delay circuit may be 111.1 nanoseconds, and the third signal generating unit needs to output a radio frequency signal with a phase angle of 240 degrees, the delay time of the second delay circuit may be 222.2 nanoseconds, that is, the time difference between adjacent signal generating units is 111.1 nanoseconds. The first delay circuit or the second delay circuit can be realized by a delay circuit formed by programmable delay chips.
Referring to fig. 4, a schematic structural diagram of another rf signal output system is shown; the system is realized on the basis of the system shown in fig. 1, and comprises a signal source module 10, a control module 11, a power driving module 12, and a power supply module 40, wherein the power supply module 40 comprises a ring-shaped isolation transformer. Specifically, the input of the toroidal isolation transformer may be 220V ac, or may be 110V ac, and the output may be a preset value, for example, 145V ac.
The power supply module is modified and realized on the basis of an AFP250-3mhz power supply; in practical implementation, the output power of each radio frequency signal can be set to be 100W, and then three radio frequency signals are 300W; the 100W is the nominal power, i.e. measured at successive full loads; the power margin of the radio frequency power supply is usually required to be more than 50%, so that the power of each radio frequency signal borne by a user is between 40 and 60W.
The power driving module comprises a power amplifier circuit and an impedance matching circuit; the power amplification circuit amplifies the power of the radio frequency signal; the impedance matching circuit is used for adjusting the impedance and the phase of the radio frequency signal so as to match the impedance and the phase with the signal output structure.
The power amplifier circuit, i.e. the power amplifier circuit, is usually used as an output stage of a multi-stage amplifier circuit. In many electronic devices, the output stage of the amplifying circuit is required to drive a certain load, or to drive an actuator in an automatic control system, and the like, so that the amplifying circuit is required to have a sufficiently large output power.
In practical implementation, the specific circuit composition of the power amplifier circuit can be selected according to practical requirements, and the following factors can be considered in selecting the power amplifier circuit: (1) maximum output power: in order to obtain a large power output, the voltage and current of the power amplifier tube are required to have a sufficiently large output amplitude. (2) Output efficiency: the output efficiency is the ratio of the useful signal power obtained by the load and the direct current power supplied by the power supply, and the higher the ratio is, the higher the efficiency is. (3) Nonlinear distortion: when the power amplifying circuit works under a large signal, nonlinear distortion is inevitably generated, and the larger the output power of the same power amplifying tube is, the more the nonlinear distortion is, so that the output power and the nonlinear distortion become a pair of main contradictions. However, the requirements for non-linear distortion vary from place to place, for example, in measurement systems and electro-acoustic equipment, the distortion problem is important, while in industrial control systems and the like, the requirements for non-linear distortion are reduced to a secondary problem with the primary purpose of output power. (4) The heat dissipation problem is as follows: in the power amplifier circuit, considerable power is dissipated at the collector junction of the tube, raising the junction temperature and the temperature of the case. Heat dissipation from the amplifier device is also a consideration in order to take full advantage of the allowable tube losses to allow the tube to output sufficient power.
The system further comprises a sampling module 41, wherein the sampling module 41 is respectively connected with the signal output interface and the signal input interface of each signal generation unit, and is used for acquiring the output parameters and the power supply voltage of each path of radio frequency signal and sending the output parameters and the power supply voltage to an external host; the output parameter includes an output current or an output voltage.
The sampling module 41 is further configured to collect power supply parameters of the power supply module and driving parameters of the power driving module; the power supply parameter comprises an alternating current input voltage; the alternating current input voltage can be collected at the output end of the annular isolation transformer; the driving parameters include alternating current, driving voltage and driving current received by the power driving module. The driving voltage generally includes three driving + B voltages and one driving 17V signal voltage, and the driving current generally includes a 17V signal current.
The sampling module can monitor and protect the working state of the radio frequency power supply, and the abnormal state waits for uploading in a fault code mode; after the sampling module collects the data, the data can be transmitted to a logic layer main control system through a communication interface, and the logic layer main control system can be arranged in an external host. The sampling module may be connected to the logic layer using an RS-422 interface.
Above-mentioned radio frequency signal output system, through the radio frequency signal of a plurality of signal generation unit output multichannel different phases, need not to improve output and can realize better treatment, the security is good and the user feels the comfort level better, has reached the unity of user comfort level and treatment. Compared with the prior art, the radio frequency signal output system has lower requirement on output power; therefore, the system is more stable, the same effect of high output power can be achieved through phase superposition, the requirement on the equipment is relatively low, and the reliability of the equipment is improved.
