Embodiment 3: as shown in fig. 5, the mini portable ultrasonic atomizer comprises a further, PCB board comprising a micro controller unit, a power supply processing unit and a transducer adjusting unit,
the microcontroller unit comprises a microprocessor module and an A/D sampling module integrated on the microprocessor module; the data processing device is used for data processing, signal data input acquisition and signal data output display of a display screen;
in the process of converting analog quantity into digital quantity by the AD converter, the AD precision in the STCl2C5410 is 10 bits, namely, the analog quantity is distributed between 0 and 1023 digital quantities. There are two types of AD conversion, a successive approximation ADC and a double integral ADC. The voltage comparator is used for comparing the voltage of the 2 end of the input end, and outputting the voltage as l if the sampling voltage is greater than the reference voltage, and outputting the voltage as l if the sampling voltage is less than the reference voltage O. For example, STCl2C5410 has an accuracy of 10, i.e., the reference voltage is divided into 1024 pieces from the lowest REF/1024 bits to the highest REF/2 bits. When the AD sampling is started, the sampling voltage is compared with the voltage from the most significant bit to the least significant bit, if the sampling voltage is larger than the output, the digital quantity output of the bit is l, and if the sampling voltage is smaller than the output, the digital quantity output of the bit is 0, and the conversion is finished.
The power supply processing unit comprises a power supply control module, a boost control module and a control circuit module; the power supply is used for respectively providing required power supplies for the circuit elements of the microcontroller module and other hardware elements of the circuit, and ensuring that each element can work normally and stably;
a boost control module: the voltage required by the microcontroller cannot be directly driven by the lithium battery, the additional booster circuit needs a certain voltage base, and the voltage stabilizing chip 7805 needs to be driven by a voltage larger than 5V. Therefore, MAX669 is selected as a boost chip to drive 7805 the power management chip and provide a certain voltage base for the boost circuit. The driving circuit converts the original 3.0V signal into a 12V voltage signal for driving the power management chip and the booster circuit. The power supply processing module is one of the core modules of the hardware system, and is also a precondition for ensuring the normal operation of the system, particularly whether the power supply voltage of the microcontroller STCl2C5410 is stable or not is directly related to whether other modules can work normally or not. The operating voltage of the microcontroller STCl2C5410 is 5V, the lithium battery voltage does not have the capability of a direct microcontroller. Therefore, in the design, the LM7805 is selected as a power management chip to provide voltage driving capability, a typical application circuit of the LM7905 is adopted, and in order to eliminate high-frequency noise, a capacitor of 0.33UF is connected between an input and the ground in series, and a capacitor of 0.1UF is also connected between an output and the ground in series. As shown in fig. 10 and 11.
A control circuit module: the PWM signal generated by the microcontroller STCl2C5410 does not have the capability to directly drive the switching MOSFET. Therefore, MCPl401 is selected as a MOSFET driver to provide additional pull/sink current capability. The driving circuit converts the signal of the original signal PWM at the high level moment into a signal of power supply voltage to drive the MOSFET. As shown in fig. 12.
The transducer adjusting unit comprises a transducer frequency, a power adjusting circuit module and an oscillating circuit module; the transducer frequency and power adjusting circuit module adjusts the oscillating circuit to adjust the frequency and power of the ultrasonic transducer; the oscillation circuit module is used for outputting oscillation alternating current to the piezoelectric ceramic piece;
transducer frequency, power conditioning circuit module: this section includes power adjustment and frequency adjustment of the transducer, i.e. adjustment of the nebulization speed, adjustment of the nebulized particles. The diameter of the atomized particles can be varied by controlling the ultrasonic frequency. The ultrasonic atomizer transducer designed by the inventor has high and low working frequencies, wherein the high frequency meets the requirement of atomized medicines with a fine particle size, and the low frequency meets the requirement of atomized medicines with a coarse particle size. The adjustment of the frequency is realized by changing the on/off state of a duty ratio control circuit of the PCA output frequency of the single chip microcomputer to charge and discharge the motor as shown in FIG. 14. The speed of particle generation can be varied by controlling the ultrasonic power. The atomizer designed by the inventor has three different power controls of high, medium and low, thereby realizing different speed requirements. The change of the ultrasonic power is mainly realized by adjusting the gain of the output electric power to adjust the output sound power of the transducer, thereby realizing the adjustment of the atomization efficiency of the atomizer. As shown in fig. 13.
An oscillation circuit module: the ceramic pellet is connected in series with a small resistor and connected across capacitor C16. The design that an inductance three-point type oscillating circuit is built through an analog circuit to complete oscillation in the past is eliminated, a single chip microcomputer directly sends PWM with PCA high-speed output and a certain frequency duty ratio to control the circuit to be conducted and closed, electric charging and discharging are carried out, and the oscillating frequency is consistent with the high-speed PCA output frequency output by the single chip microcomputer. This has the advantage that the frequency control is more stable and the oscillation frequency can be controllably adjusted. The output Vout is 12V, and the MOSFET tube IRFRlN60A controlled by the PWM output driven by the MCPl401 is opened and closed. When the PWM is at the high time, the MOSFET IRFRlN60A turns on, and the voltage will go from the output Vout to the MOSFET and then through R17 to GND. This forces the capacitor C14 to ground. When the MOSFET IRFRlN60A is turned off when the PWM is low, the inductor L3 prevents the current change from charging the capacitor C14. The diode of the BOOST booster circuit is replaced by a capacitor C14, and the diode is placed between GND and the source of the MOSFET. This has the advantage of discharging C16 when the PWM is high. As shown in fig. 14.
The power supply processing unit and the transducer adjusting unit are connected to the microcontroller unit.
Furthermore, the A/D sampling module comprises a power supply voltage detection circuit, an atomized wafer detection circuit and a water level height sensor detection circuit;
the power supply voltage detection circuit is mainly used for detecting whether a current lithium battery or a 9V power supply supplies power or not, when the lithium battery or the 9V power supply has voltage, ADl sampled voltage is voltage on R20, and AD sampling is carried out to analyze current electric quantity. ADl is at a low level when no voltage is supplied from the lithium battery or the 9V power supply, and the voltage is 0. As shown in fig. 7.
The atomized wafer detection circuit is mainly used for detecting whether the atomized wafer works currently or not. When the atomizer chip is not in operation or connected, the diode is turned off due to the unidirectional conductivity of the diode D5-4148 when a voltage of 5V is connected to the reverse input terminal of the diode D7.4148, and similarly GND is connected to the forward input terminal of the diode D7.4148, so that when ADO has a voltage, D7-4148 is turned off due to the unidirectional conductivity of the diode. The advantage of this design is that the oscillating voltage of the atomizing wafer is high, when the high voltage comes to turn on D4-4148, because the voltage is greater than 5V at this moment, D5-4148 will turn on in the forward direction, stabilizing the voltage at 5.7V, so that the ADO port will not be burnt out due to the excessive voltage. When the net type ultrasonic atomizer system emits PWM waves with PCA high-speed output, voltage can pass through one end of the OSC by the atomizing wafer with high-frequency oscillation, if the voltage is not more than 5.7V, the voltage passes through diodes D4-414 at the moment and then passes through R18 to GND, and the voltage sampled by ADO is the voltage value of R12 and R18. If the voltage is larger than 5.7V at the moment, the voltage sampled by the ADO port is basically the voltage of the current positive input end of D5-4148. As shown in fig. 8.
The water level sensor detection circuit selects SM5812, which is a typical piezoresistive pressure sensor. SM5812 is a silicon microstructure OEM pressure sensor, a high performance pressure sensor with amplification, full calibration, multi-step pressure correction and temperature compensation dual inline packaging produced combining advanced cmos digital signal processing technology and the most advanced pressure sensor processing technology. The sensor output is the basic analog value, and finally the low power consumption and high sensitivity can be directly connected with a microprocessor or other logic circuits, so that the sensor is suitable for various development boards and controllers. The 5V DC constant voltage source supplies power, and a 100nF filter capacitor is arranged between the ground and the power supply pin to provide a calibration analog output for the power supply pin. As shown in fig. 9.
The boost control module circuit adopts a MAX669 boost chip to drive a LM7805 power management chip, and the control circuit module circuit adopts a MCPl401 chip.
Further, the microprocessor module adopts a single-clock STCl2C5410AD single chip microcomputer with the machine period of 1T. The microprocessor selects a single-chip microcomputer with a single clock and a machine period (1T) which is produced by a macro-crystal science and technology company. The normal working voltage of the microcontroller STCl2C5410 is 3.5V and 5V, the working frequency is 0-35 MHZ, and the system can work normally. In addition, a MAX810 special reset circuit, 4 paths of PWM and 8 paths of 10-bit precision high-speed A/D conversion are integrated in the microcontroller, and the microcontroller is strong in adaptive interference. The system comprises a UART serial port, an I/O interface, a high-speed A/D conversion module, an SPT interface, a PCA (principal component analysis), a watchdog, an on-chip R/C (radio/communication) oscillator, an external crystal oscillation circuit and the like. And finally, considering the relation between comprehensive performance and price to finally select the STCl2C5410 chip. The minimum system circuit and part of the interface circuit of the microcontroller STCl2C5410 are shown in fig. 6.
Furthermore, when the switch is closed or rebounds, voltage jitter is brought to the loop, and the voltage jitter brought by the key is absorbed by an RC circuit formed by a capacitor and a resistor in the circuit. When the key switch is closed, the capacitor C starts to charge for 3-5RC time due to key shaking, and the capacitor charging process is finished. Within 3-5RC, once the input reaches the forward threshold voltage of the reverse Schmitt trigger, the reverse Schmitt trigger outputs a low level signal. Similarly, when the key switch is released, the capacitor starts to discharge, and when the input voltage of the Schmitt trigger is lower than the negative threshold voltage of the reverse Schmitt trigger, the reverse Schmitt trigger outputs a high-level signal. Thus, the key anti-shake work at the hardware end is completed. The value can be taken according to the value of the resistance value according to the specific time of the jitter, and the time for charging the capacitor in the circuit is increased or reduced, so that the jitter operation of the RC circuit capable of absorbing the interference can be ensured. Due to the design, in the operation process of the mesh-type ultrasonic atomizer, the mechanical structure which can be controlled by the key circuit switch is used for starting atomization, namely, an operator uses the mesh-type ultrasonic atomizer to start atomization by operating the key circuit switch, and the internal mechanical structure in the operation process can trigger the corresponding key switch to send excitation to the system. However, certain errors are certainly existed in the mechanical structure in the processing process, the errors among the parts can influence the precision of the action in the manual operation process, and the influence on the precision is reflected in the excitation of the key to the system, namely the key shaking. The response form to the key excitation in the design is external interruption, when the jitter phenomenon is serious, the wrong response of software to the external interruption is inevitably caused, and the software system is down under the serious condition. The shake caused by the error of the mechanical connection part has more uncertainty, and the software shake-proof mode can not be completely eliminated, so the key shake-proof circuit is added between the microprocessor and the key to overcome the defects. As shown in fig. 15.
The mini portable ultrasonic atomizer is simple in structure, convenient to carry, capable of adjusting the size and the speed of atomized particles, high in control precision, capable of fully utilizing the performance advantages of a single chip microcomputer in the field of embedded control, achieving functions of intelligent detection, automatic control, personalized adjustment and the like, guaranteeing real-time reliability of a system, and capable of meeting use requirements of different medicine properties.
