FIG. 1A is a schematic block diagram of an atomization system according to a first embodiment of the present invention, and FIG. 1B is a schematic structural diagram of the atomization system shown in FIG. 1A . Please refer to FIG. 1A and FIG. 1B at the same time, the atomization system S can be applied to medical care or beauty care, and this embodiment is described with a medical drug atomization system. In this embodiment, the atomization system S includes an atomizer 1 and a power adapter 2 , and the power adapter 2 is detachably connected to the atomizer 1 and can supply power to the atomizer 1 .

Please also refer to FIG. 1C , which is an exploded view of the nebulizer 1 . The atomizer 1 includes an atomization drive device 11 and an atomization module 12 , and the atomization drive device 11 is connected to the atomization module 12 and can drive the atomization module 12 to generate spray. In this embodiment, the atomization driving device 11 and the atomization module 12 are designed to be detachable, for example, connected by buckles or sliding slots. In this way, when the user wants to clean the atomization module 12, the atomization drive device 11 and the atomization module 12 can be separated, and only the atomization module 12 is cleaned, thereby preventing the electronic components in the atomization drive device 11 from being damp. and damaged. In other embodiments, the atomization driving device 11 and the atomization device 12 may also be inseparable, which is not limited by the present invention.

The atomization driving device 11 includes an input terminal 111, a battery unit 112, a switching unit 113, a voltage detection unit 114, a voltage adjustment unit 115, a driving unit 116, a pulse width modulation unit 117 and a control unit 118 . What needs to be explained first is that the pulse width modulation unit 117 is optional. In the embodiment without the pulse width modulation unit 117, the atomization drive device 11 can still operate normally. The configuration of the variable unit 117 can also improve the power management efficiency of the atomization driving device 11, which will be described later.

The control unit 118 is coupled to the switch unit 113 , the voltage detection unit 114 , the voltage adjustment unit 115 and the pulse width modulation unit 117 to receive signals from the above units or control the actions of the above units. The control unit 118 may be implemented by a digital circuit such as an integrated circuit (IC), or an analog circuit. The integrated circuit may be, for example, a microprocessor (Micro-processor), a microcontroller (MCU), a programmable logic gate array (FPGA or CPLD), or an application-specific integrated circuit (ASIC), and the present invention is not limited thereto. In addition, in an embodiment without the PWM unit 117 , the control unit 118 is directly coupled to the driving unit 116 , or the control unit 118 is not coupled to the driving unit 116 .

The input end 111 can be coupled to the power adapter 2 so that the power adapter 2 supplies power to the atomization driving device 11 . The input end 111 is also coupled to the battery unit 112 at the same time, so that the battery unit 112 can be used as a power source for the atomization driving device 11 when the atomizer 1 is not connected to the mains.

One end of the switching unit 113 is coupled to the input end 111 , and the other end is coupled to the battery unit 112 . The voltage detection unit 114 is coupled to the input terminal 111 and can detect whether the voltage of the input terminal 111 is greater than a set value. In this embodiment, when the power adapter 2 is coupled to the input terminal 111 to provide commercial power, the voltage that the power adapter 2 can provide is higher than the voltage that the battery unit 112 can provide, and the setting value is set at these two voltages Between, for example, the power adapter 2 provides a voltage of 5 volts, while the battery unit 112 provides a voltage of 3 volts, and the set value at this time may be, for example, a voltage of 4 volts. Therefore, when the voltage detection unit 114 detects that the voltage at the input terminal is greater than the set value and returns the detection result to the control unit 118, the control unit 118 judges that the power adapter 2 has been coupled to the input terminal 111 at this time, and the power adapter 2 also provides Mains power to the atomizer 1, and then the control unit 118 controls the switching unit 113 to cut off (or disconnect), so that the battery unit 112 will not provide power to the input terminal 111, and at the same time prevent the battery unit 112 from being mischarged by the mains power, and then The battery unit 112 is protected without affecting its service life.

Continuing from the above, when the voltage detection unit 114 detects that the voltage at the input terminal 111 is lower than the set value and returns the detection result to the control unit 118, the control unit 118 judges that the power adapter 2 does not provide commercial power to the atomizer 1, for example, The power adapter 2 is not coupled to the input end 111 , or the power adapter 2 is coupled to the input end 111 but not connected to the mains. At this moment, the control unit 118 controls the switching unit 113 to be turned on, so that the battery unit 112 serves as a power source. In practice, the circuit diagram of the voltage detection unit 114 may refer to FIG. 8A .

Specifically, please refer to FIG. 2 , which is a schematic circuit diagram of the switching unit. The switching unit 113 may include a switch 1131 and a diode 1132. One end of the switch 1131 is coupled to the battery unit 112 and the anode end of the diode 1132, and the other end of the switch 1131 is coupled to the input end 111 and the cathode end of the diode 1132, and the switch 1131 The control terminal of is coupled to the control unit 118 . Here, the control unit 118 can determine whether the control switch 1131 is turned off or turned on as described above. In addition, in some embodiments, the switching unit 113 can also be realized by only one switch 1131 or only one diode 1132 , which is not limited by the present invention.

The voltage adjustment unit 115 adjusts the input voltage received by the input terminal 111 to a working voltage and outputs it to the driving unit 116 , wherein the input voltage can be provided by the power adapter 2 or the battery unit 112 . In practice, the voltage adjustment unit 115 may be, for example, a boost circuit, a buck circuit or a boost-buck circuit, which is not limited herein.

The driving unit 116 is coupled to the voltage adjustment unit 115 , and drives the vibration unit 121 of the atomization module 12 to vibrate according to the output voltage of the voltage adjustment unit 115 to generate spray. Vibration unit 121 can be a piezoelectric (piezo) material. Vibration is generated by applying a voltage to the piezoelectric material, and then the liquid medicine is converted into a spray. The higher the applied voltage, the greater the vibration and thus the greater the spray volume. many. In practice, the circuits of the voltage adjusting unit 115 and the driving unit 116 can be referred to as shown in FIG. 8B , wherein the aforementioned voltage adjusting unit 115 can be formed by using the commercial power supply chip U2. In addition, other variations of the driving unit 116 may refer to FIG. 8C and FIG. 8D .

FIG. 3A is a waveform diagram of an input voltage of a driving unit. Please refer to FIG. 1A and FIG. 3A together. In this embodiment, the control unit 118 can determine the working voltage according to the power source. When the mains supply power, the control unit 118 sets the atomization driving device 11 to the general driving mode (or the first driving mode), and when the battery unit 112 supplies power, the control unit 118 sets the atomization driving device 11 to the energy-saving driving mode (or second drive mode). In the general driving mode, the voltage adjustment unit 115 can adjust the input voltage to the first working voltage V1 (for example, 10 volts) and output it, and in the energy-saving driving mode, the voltage adjusting unit 115 can adjust the input voltage to the second working voltage V1. The voltage V2 (for example, 8 volts) is output, wherein the first working voltage V1 is greater than the second working voltage V2. In this way, in the energy-saving driving mode, the battery unit 112 can provide a lower power supply instead of the first working voltage V1, thereby prolonging the power supply time of the battery unit 112 . In addition, the second working voltage V2 can be 60% to 80% of the first working voltage V1, so as to save energy while not affecting the therapeutic effect.

3B and 3C are waveform diagrams of another input voltage of the driving unit, respectively. Please refer to FIG. 1A and FIG. 3B, the pulse width modulation unit 117 is coupled to the drive unit 116, and can generate a pulse width modulation signal to control the duty cycle T of the drive unit 116. For example, the duty cycle T can be 50%, that is The period of drug supply is equal to the period of drug withdrawal. In some embodiments, regardless of the normal driving mode or the energy-saving driving mode, the PWM unit 117 generates a PWM signal with the same duty cycle T, that is, the duty cycle is not affected by the driving mode. Referring next to FIG. 1A and FIG. 3C , in some other embodiments, the control unit 118 can control the pulse width modulation unit 117 to generate a pulse width modulation signal with a shorter duty cycle T in the energy-saving driving mode, such as working The period T is adjusted to 45%, which can also save the power consumption of the battery unit 112 and prolong the service time of the battery unit 112 .

FIG. 4A is a schematic block diagram of an atomization system according to a second embodiment of the present invention, and FIG. 4B is a schematic structural diagram of the atomization system shown in FIG. 4A . Please refer to FIG. 4A and FIG. 4B at the same time, this embodiment is substantially the same as the first embodiment, the difference is that the atomization system S1 of this embodiment further includes an auxiliary component 3 . The auxiliary part 3 can be a mask or a catheter, and this embodiment uses a mask as an example for illustration. The auxiliary component 3 has a breathing detection unit 31 , and the breathing detection unit 31 is coupled to the control unit 118 . In this embodiment, the breathing detection unit 31 can detect the breathing state of the user, and transmit the detection result to the control unit 118 , and the control unit 118 can control whether the driving unit 116 operates or not.

Fig. 4C is a schematic diagram of an accessory. Please refer to Fig. 4A, Fig. 4B and shown in Fig. 4C together, in the present embodiment, breathing detection unit 31 is a micro switch (micro switch), and the face shield (auxiliary part 3) is provided with film, and film and micro switch set for the neighbors. When the user wears a face mask for spray treatment, during the inhalation process, the user will suck the membrane towards the user, causing the micro switch to be activated by the extrusion of the membrane, and then send a signal to the control unit 118, and then the control unit 118 According to this, the driving unit 116 is actuated to provide the medicine mist to the user. On the other hand, in the process of exhaling, the user will blow the film away from the micro-switch, so that the micro-switch will not be squeezed by the film and close. At this time, because the control unit 118 does not receive the signal from the micro-switch, it controls the drive unit 116 does not generate action, so that the medicine mist will not be provided to the user, which can prevent the user from exhaling the medicine mist and wasting medicine.

Wherein, the control unit 118 controls whether the drive unit 116 operates or not, for example, by setting a switch between the pulse width modulation unit 117 and the drive unit 116, and controlling the on and off of the switch, or by controlling A switch is provided between the unit 118 and the pulse width modulation unit 117 to implement, and the present invention is not limited here.

It should be noted that although this embodiment is described as an example of drug administration by triggering the breath detection unit 31 when inhaling, in practice, the nebulizer 1 can also be stopped by triggering the breath detection unit 31 when exhaling. Administration is not limited here.

In addition, in some embodiments, the breathing detection unit 31 may be an infrared detector or a sound source detector. The infrared detector can detect the airflow fluctuations in breathing, and then judge whether the user is in the state of exhalation or inhalation. The sound source detector can detect the sound when the user exhales and inhales, and judges the breathing state of the user accordingly.

It is worth mentioning that the driving mode in which the drug is administered by detecting breathing in this embodiment can also be combined with the driving mode in the previous embodiment. For example, in the energy-saving driving mode, when the breathing detection unit 31 detects the user’s inhalation, the control unit 118 can control the driving unit 116 to act, and at this time the input voltage of the driving unit 116 is the second working voltage V2, or At this time, the PWM unit 117 generates a PWM signal with a duty cycle of 45%, and when the breathing detection unit 31 detects the user's exhalation, the control unit 118 controls the driving unit 116 to stop. Similarly, the general driving mode can also be combined with this embodiment, which will not be repeated here.

In addition, please refer to FIG. 5 , which is a waveform diagram of the breathing cycle of the user and the input voltage of the driving unit in the smart driving mode. The atomization system S1 of this embodiment can also provide an intelligent driving mode (or a third driving mode). In the intelligent driving mode, the control unit 118 can control the actuation timing and stop timing of the driving unit 116 to achieve the effect of pre-medication, or the synchronization between the timing of administration and the timing of inhalation. Furthermore, the control unit 118 can count the frequency and cycle of the user's breathing, and calculate the average value of the breathing frequency and cycle, so as to predict the period of the user's next inhalation. In this way, the control unit 118 can control the driving unit 116 to actuate slightly earlier than the time point of the user's inhalation, or synchronize the drug administration with the time point of the user's inhalation, so as to solve the problem that the control unit 118 receives breath detection. The unit 31 controls the actuation of the driving unit 116 to delay the administration after detecting the user's inhalation.

FIG. 6A is a schematic block diagram of an atomization system S2 according to the third embodiment of the present invention. Please refer to Fig. 6A at the same time, this embodiment is roughly the same as the first embodiment, the difference is that the atomizer 1a of this embodiment does not use the voltage detection unit 114 to determine whether the power source is the mains or the battery unit 112, but The power source is judged by the current detection unit 114a. In this embodiment, the current detection unit 114 a is coupled to the input terminal 111 , the voltage adjustment unit 115 and the control unit 118 . The current flows through the current detection unit 114a, and is generated or converted into a voltage signal and provided to the control unit 118 as current information. The current provided by the battery unit 112 or the power adapter 2 will flow to the current detection unit 114a, and the current detection unit 114a can judge the power source according to whether the current is greater than the set value, for example, if it is greater than the set value, it is judged to be commercial power When the value is less than the set value, the battery unit 112 is powered, or for example, when the value is greater than the set value, it is determined that the battery unit 112 is powered, and when the value is less than the set value, the mains power is supplied. In practice, the current detection unit 114a can be, for example, a resistor, a current transformer, or a Hall element, or other elements capable of detecting current, which is not limited here. In other embodiments, the detected current value can clearly identify the current input current according to the input voltage. For example, when the input voltage is provided by the power adapter 2, the input voltage is 5V and the current is 0.25A, or the input When the voltage is provided by a new battery (battery unit 112 ), the voltage is 3V and the current is 0.42A. That is to say, under the setting of the rated power, the higher the input voltage, the smaller the current. Therefore, it can be further judged whether the power source is the mains (power adapter 2 ) or the battery unit 112 according to the detected current.

In addition, the input end 111 of this embodiment is coupled to the switch unit 113 , that is, the current provided by the power adapter 2 will flow through the switch unit 113 to the current detection unit 114 a, and then flow to the voltage adjustment unit 115 . Wherein, the components and operations of the switching unit 113 have been described in detail in the above embodiments, and will not be repeated here.

It is worth mentioning that, in some embodiments, the voltage detection unit 114 and the current detection unit 114a exist at the same time, as shown in FIG. 6B for example. Wherein, the voltage detection unit 114 is used to determine the power source, as described in the foregoing embodiments, and the current detection unit 114a is used to adjust the power. Furthermore, the control unit 118 can determine the power source according to the voltage value of the input voltage detected by the voltage detection unit 114 , and then calculate the power according to the current value of the input current detected by the current detection unit 114 a. When the control unit 118 judges that the calculated power is too high or too low, the control unit 118 can adjust the resistance of the voltage adjustment unit 115 to maintain the rated power. In one embodiment, a circuit diagram of the current detection unit 114a is shown in FIG. 8E .

Fig. 7 is a flow chart of steps of a method for driving an atomization system according to a preferred embodiment of the present invention. Please refer to FIG. 1A, FIG. 1B and FIG. 7 at the same time. The driving method of this embodiment is applied to the atomization system, such as the atomization system S of the above-mentioned first embodiment or the atomization system S1 of the second embodiment. , here is the atomization system S of the first embodiment for description. Wherein, the components and operation of the atomization system S have been described in detail above, and will not be repeated here. The driving method of this embodiment includes the following steps: detecting whether the input voltage is less than the voltage of the battery unit (S01); if so, stopping the operation (S02); if not, detecting whether the input voltage is less than a set value (S03); Set value, enter the energy-saving drive mode (S04); when the input voltage is greater than the set value, enter the general drive mode (S05).

In step S01, when the atomizer 1 is not connected to the commercial power and the battery unit 112 is low in power, the voltage detection unit 114 detects that the input voltage is lower than the voltage of the battery unit 112, and the control unit 118 will stop the operation of the drive unit 116 (ie Step S02). On the contrary, if the input voltage is greater than the voltage of the battery unit 112 , it will enter step S03 to further determine whether the input voltage is less than the set value.

In step S04, when entering the energy-saving driving mode, that is, the battery unit 112 supplies power, and the input voltage at this time is the second working voltage. In practice, the pulse width modulation unit 117 can be used to reduce the duty cycle T of the driving unit 116 to further reduce the power consumption of the battery unit 112 and prolong the service time of the battery unit 112 .
