1 is a functional block diagram of a liquid atomizing circuit according to an embodiment of the present invention. Please refer to Figure 1. A liquid atomizing circuit 1 suitable for controlling a liquid atomizing spray module 14. The liquid atomizing circuit 1 includes a driving unit 12 and a control unit 10. The control unit 10 is coupled to the driving unit 12 and the spray module 14 . The driving unit 12 is coupled to the spray module 14 .

In practice, the control unit 10 is configured to control the driving unit 12 to output a driving voltage. The driving unit 12 is configured to output a driving voltage to directly drive the spray module 14. For example, the control unit 10 outputs a control signal to the driving unit 12, so that the driving unit 12 outputs a driving voltage to the spray module 14. Therefore, the spray module 14 produces micro-mist particles having a particle size of about 3 to 5 μm, so that the micro-mist particles effectively reach the alveoli and are directly absorbed by the human body.

In detail, the control unit 10 is, for example, a control chip, a micro control chip or a PWM control chip, and the embodiment does not limit the aspect of the control unit 10. The control unit 10 has a plurality of connection ports for outputting pulse modulation signals, and the frequency adjustment range is, for example, 10 Hz to 1 MHz, and the Duty Cycle adjustment range is, for example, 10% to 90%. In practice, control unit 10 may output one or more control signals. The control signal is used to control the operation of the driving unit 12.

The driving unit 12 is, for example, a driving circuit including one or more switches, one or more inductors, one or more capacitors and diodes. This embodiment does not limit the aspect of the drive unit 12. The driving unit 12 is configured to receive the control signal output by the control unit 10. In practice, the driving unit 12 supplies the driving module 14 with a driving voltage that vibrates at the output frequency according to the control signal. The driving voltage is, for example, a pulsating DC voltage. The waveform of the driving voltage is, for example, a sine wave, a triangular wave, or a square wave.

The spray module 14 includes, for example, a nozzle member (not shown) and a piezoelectric sheet (not shown). Wherein, the orifice member is disposed on the piezoelectric sheet. The orifice member is, for example, a vibrating piece having a plurality of fine perforations. The piezoelectric sheet is, for example, a piezoelectric actuator that vibrates at a frequency. The orifice member and the piezoelectric sheet can be designed in one piece or in combination.

The spray module 14 has a first pin P1 and a second pin P2. The first pin P1 is coupled to the driving unit 12, and the second pin P2 is coupled to the control unit 10. For convenience of explanation, the first pin P1 is, for example, a pin of the positive terminal of the spray module 14. The second pin P2 is, for example, a pin of the negative terminal of the spray module 14. This embodiment does not limit the spray The aspect of the mist module 14.

In addition, the control unit 10 outputs a predetermined voltage to the spray module 14. The preset voltage is, for example, a positive level voltage greater than zero voltage, such as +10V, +20V, +40V or any other positive value volt. In general, conventional liquid atomizing circuits are required to pass a conversion circuit to convert a voltage to a spray module. And one of the two pins of the conventional spray module is grounded. For example, the first pin of the conventional spray module is coupled to the conversion circuit, and the second pin is coupled to the ground. Therefore, the conventional liquid atomizing circuit tends to consume more electric energy, and the second pin coupled to the ground often receives more minute noise.

However, the liquid atomizing circuit 1 of the present embodiment transmits the spray module 14 directly through the driving unit 12, thereby reducing the conversion or loss of electric energy. Moreover, the second pin P2 of the spray module 14 of the embodiment is not grounded. The second pin P2 is coupled to the control unit 10 to receive a predetermined positive level voltage. Therefore, compared with the conventional second pin, the second pin P2 of the embodiment can receive the preset positive level voltage, and the conventional micro noise is relative to the preset positive level voltage. The tiny noise can be almost ignored or omitted. Therefore, compared with the conventional liquid atomizing circuit, the liquid atomizing circuit 1 of the present embodiment has lower power loss, the signal received by the grounding end of the printed circuit board is cleaner, and the spray performance is better. .

It is worth mentioning that the spray module 14 is contacted or immersed in the liquid, provides a driving voltage to the spray module 14 in the driving unit 12 of the present invention, and the control unit 10 provides a predetermined voltage to the spray module 14 The spray module 14 generates a forward electrolysis reaction and a reverse electrolysis reaction according to the driving voltage and the preset voltage. For example, when the driving voltage is greater than the preset voltage, the spray module 14 performs a forward electrolysis reaction; when the driving voltage is less than the preset voltage, the spray module 14 performs a reverse electrolysis reaction.

That is to say, the spray module 14 of the present invention transmits the forward electrolysis reaction and the reverse electrolysis reaction, thereby slowing down the rate at which the first and second electrodes of the spray module 14 generate electrolytic substances. Therefore, the spray module 14 at the first pole and the second pole will slow down the opportunity to adhere to the electrolyte, thereby increasing the service life of the spray module 14 or the liquid atomizing device.

2 is a schematic diagram of a liquid atomization circuit of another embodiment of the present invention. Please refer to Figure 2. This embodiment will further illustrate the detailed components, circuitry, and operation of the drive unit 12. The driving unit 12 includes a first switch Q1, a second switch Q2, a first one-way conducting component D1, a first inductor L1, a second inductor L2, and a first capacitor C.

In practice, the control terminal G of the first switch Q1 is coupled to the control unit 10. The first end S of the first switch Q1 is coupled to a ground GND. The second end D of the first switch Q1 is coupled to a first inductor L1 and a first one-way conducting component D1. The first end S of the first switch Q1 is, for example, a source terminal, and the second end D of the first switch Q1 is, for example, a 汲 terminal. The first one-way conducting element D1 is, for example, a diode or a Schottky Diode.

The control terminal G of the second switch Q2 is coupled to the control unit 10, the first end S of the second switch Q2 is coupled to the ground GND, and the second end D of the second switch Q2 is coupled to a second inductor L2 and the spray module 14 The first pin P1. The first capacitor C is coupled between the first one-way conducting component D1, the second inductor L2, and the ground GND. The first end S of the second switch Q2 is, for example, a source terminal, and the second end D of the second switch Q2 is, for example, a 汲 terminal.

Therefore, the control unit 10 can control the first switch Q1 to be turned on or off to charge or discharge the first inductor L1; or the control unit 10 can control the second switch Q2 to be turned on or off to charge the second inductor L2 or Discharge. The control unit 10 can control the on or off of the first and second switches Q1 and Q2 through interleaving control, synchronous control or other control modes. This embodiment does not limit the operational aspect of the liquid atomizing circuit 1.

In addition, the anode of the first one-way conducting component D1 is coupled to the first inductor L1, and the cathode of the first one-way conducting component D1 is coupled to the second inductor L2 and the first capacitor C. The first inductor L1 is coupled to an operating voltage VCC. It can be seen that the control unit 10 controls the on or off operations of the first and second switches Q1, Q2, so that the driving unit 12 outputs a driving voltage to directly drive the spray module 14. And the control unit 10 outputs a pre- A voltage is applied to the spray module 14. Therefore, the piezoelectric piece of the spray module 14 is largely deformed according to the driving voltage and the preset voltage, whereby the sound wave oscillates to increase the amount of spray of the micro-mist.

FIG. 3 is a schematic diagram of a driving voltage waveform of a spray module according to another embodiment of the present invention. FIG. 3A is a schematic diagram of a preset voltage waveform of a spray module according to another embodiment of the present invention. FIG. 3B is a schematic diagram showing the waveforms of the driving voltage and the preset voltage of the spray module according to another embodiment of FIG. 3 and FIG. 3A. Please refer to FIG. 3, FIG. 3A and FIG. 3B.

The waveform of the driving voltage received at the first pin P1 of the spray module 14 is as shown in FIG. The waveform of the driving voltage shown in FIG. 3 is, for example, a pulsed triangular wave, and the peak is, for example, 50 V, and the voltage waveform of the driving voltage is a voltage greater than 0 volt. That is, the voltage waveform of the driving voltage shown in FIG. 3 is, for example, a pulse triangular wave voltage of 0 to 50 volts, and the frequency is about 120 kHz. Next, the waveform of the preset voltage received at the second pin P2 of the spray module 14 is as shown in FIG. 3A. The waveform of the preset voltage illustrated in FIG. 3A is a positive level bias voltage, for example, 10V.

In FIG. 3B, FIG. 3 and FIG. 3A are combined, that is, the driving voltage and the preset voltage respectively received by the first and second pins P1 and P2 of the spray module 14. The spray module 14 generates a forward electrolysis reaction and a reverse electrolysis reaction according to the driving voltage and the preset voltage. In practice, when the driving voltage is greater than the preset voltage, the spray module 14 performs a forward electrolysis reaction, such as the forward electrolysis section PA in FIG. 3B. When the driving voltage is less than the preset voltage, the spray module 14 performs a reverse electrolysis reaction, such as the reverse electrolysis section NA in FIG. 3B.

In practice, the forward electrolysis section PA means "a short circuit occurs between the first pole and the second pole of the spray module 14 immersed in the liquid". Specifically, when a short circuit occurs between the first pole and the second pole of the spray module 14, an electrolytic current is generated between the first pole and the second pole. Thereby the electrolytic substance in the liquid is dissociated and will adhere to the first pole and the second pole. The forward electrolysis reaction refers to a first pole and a second pole of the spray module 14 The body produces an electrolytic reaction, the anion dissociated from the liquid swims toward the first pole, and the cation dissociated from the liquid swims toward the second pole.

The reverse electrolysis section NA means "converted to the first pole of the negative electrode and to the second pole of the positive electrode". The reverse electrolysis reaction means that the first pole and the second pole of the spray module 14 generate an electrolytic reaction with the liquid, the anion dissociated from the liquid swims to the second pole, and the cation dissociated from the liquid swims toward the first pole. Wherein, the first pole and the second pole are soldered to the same surface of the piezoelectric sheet, for example, and are contacted or immersed in the liquid. When the driving voltage and the preset voltage are received by the piezoelectric piece of the spray module 14, the piezoelectric piece generates an electrolytic reaction with the liquid according to the driving voltage and the preset voltage.

For example, the voltage waveform in Figure 3B includes a plurality of reverse electrolysis sections NA and a plurality of forward electrolysis sections PA. For example, when the driving voltage is less than 10 volts, that is, the reverse driving phase NA of "the driving voltage is less than the preset voltage", the piezoelectric sheet reacts with the liquid in a reverse direction. On the other hand, for example, when the driving voltage is greater than 10 volts, that is, the forward electrolysis section PA of "the driving voltage is greater than the preset voltage", the piezoelectric sheet generates a forward electrolysis reaction with the liquid. In addition, the piezoelectric sheet produces the effect of liquid atomization in accordance with the driving voltage to form a sound wave oscillation.
