That is, one device can realize the functions of electrolysis and spraying, eliminating the need to use an electrolysis device and a sprayer simultaneously as in the prior art, thus alleviating the technical problem of high equipment cost caused by the need to use an electrolysis device and a sprayer simultaneously in the current electrolytic atomization technology.

[0074] In some embodiments, the power supply circuit includes: a power supply Ui, a first current-limiting resistor R1, a second current-limiting resistor R2, a first switching transistor Q1, a first diode D4, an inductor L, and a DC blocking capacitor C3; wherein: the first end of the first current-limiting resistor R1 is electrically connected to the pulse signal output terminal; the first end of the second current-limiting resistor R2 is grounded; the gate of the first switching transistor Q1 is electrically connected to the second end of the first current-limiting resistor R1 and the second end of the second current-limiting resistor R2; the first end of the first diode D4 is electrically connected to the first signal terminal of the first switching transistor Q1, and the second end of the first diode D4 is electrically connected to the second signal terminal of the first switching transistor Q1; the first end of the inductor L is electrically connected to the second signal terminal of the first switching transistor Q1, and the second end of the inductor L is electrically connected to the power supply; the first end of the DC blocking capacitor C3 is electrically connected to the first end of the inductor L, and the second end of the DC blocking capacitor C3 is electrically connected to the first electrode contact.

[0075] In some embodiments, the current detection circuit includes: a first sampling resistor R3, a first filter capacitor C2, and a first current detection output terminal (i.e., Figure 4 The current detection port 1 in the chip is configured such that: the first end of the first sampling resistor R3 is grounded, and the second end of the first sampling resistor R3 is electrically connected to the sampling end of the first switching transistor Q1; the first end of the first filter capacitor C2 is grounded, and the second end of the first filter capacitor C2 is electrically connected to the second end of the first sampling resistor R3; the first current detection output terminal is electrically connected to the second end of the first sampling resistor R3 and connected to the second input terminal of the control chip.

[0076] In some embodiments, the liquid level detection circuit includes: a second sampling resistor R4, a first voltage divider resistor R5, a second diode D1, a third diode D2, a second voltage divider resistor R6, a second filter capacitor C4, and a liquid level detection output terminal (i.e., Figure 4 Voltage detection port 1); wherein: the first end of the second sampling resistor R4 is grounded, and the second end of the second sampling resistor R4 is connected to the second electrode contact ( Figure 4The diagram shows the negative piezoelectric ceramic, i.e., the second piezoelectric ceramic sheet. Since the second piezoelectric ceramic sheet is electrically connected to the second electrode contact, the second end of the second sampling resistor R4 is also electrically connected to the second electrode contact. The first end of the first voltage divider resistor R5 is electrically connected to the second electrode contact. The first end of the second diode D1 is electrically connected to the second end of the first voltage divider resistor R5.

The liquid level detection output terminal is electrically connected to the second end of the second filter capacitor C4 and connected to the third input terminal of the control chip.

[0077] Specifically, during the atomization stage, to prevent dry burning, the solution level in the solution chamber needs to be monitored. The atomization circuit during this stage consists of: inductor L, NMOS transistor Q1, resistors R3 and C3, positive electrode plate, solution, atomizing metal plate (positive piezoelectric ceramic plate), negative piezoelectric ceramic plate, and resistor R4. Atomization control method: When the atomization function is activated, PWM is started, and the Q1 NMOS transistor generates a high-frequency switch. The electrolytic negative electrode switch contact opens, and the electrolytic positive electrode (atomization positive electrode contact) generates a high-frequency pulse voltage. This pulse voltage is transmitted to the atomizing metal plate through the conductivity of the disinfectant, causing the atomizing plate to vibrate at high frequency, thus forming atomization. When the voltage detected by voltage detection port 1 is greater than the set value 2, it indicates that there is no liquid in the solution chamber, the PWM output stops, and atomization stops.

[0078] In some embodiments, the electrolysis enabling circuit includes: a second switching transistor Q2, a fourth diode D5, a fifth diode D3, a pull-up resistor R7, a transistor Q3, a third voltage divider resistor R8, a fourth voltage divider resistor R9, and a second current detection output terminal (i.e., Figure 4 Current detection 2); wherein: the first terminal of the fourth voltage divider resistor R9 is connected to the electrolysis enable signal terminal (i.e. Figure 4In the electrolytic enable 1) electrical connection, the second end of the fourth voltage divider resistor R9 is electrically connected to the first end of the third voltage divider resistor R8 and the gate end of the transistor Q3; the second end of the third voltage divider resistor R8 is grounded; the first signal end of the transistor Q3 is grounded, and the second signal end of the transistor Q3 is electrically connected to the first end of the pull-up resistor R7 and the gate of the second switching transistor Q2; the first signal end of the second switching transistor Q2 is electrically connected to the first end of the fourth diode D5 and the first end of the fifth diode D3, and the second signal end of the second switching transistor Q2 is electrically connected to the second end of the pull-up resistor R7, the second end of the fourth diode D5, and the power supply Ui; the second end of the fifth diode D3 is electrically connected to the first electrolytic chip; the second current detection output end is electrically connected to the second end of the pull-up resistor R7 and connected to the fourth input end of the control chip.

[0079] Q2 is an N-type field-effect transistor, which can be replaced by switching devices with switching functions such as IGBTs, optocouplers, and relays. Figure 4 The electrolytic negative electrode switch contacts can be devices with switching functions such as N-type field-effect transistors, IGBTs, optocouplers, and relays.

[0080] Specifically, during the electrolysis stage, the electrolysis circuit consists of: current detection module 2, Q2 nmos transistor, D3, positive electrode plate, solution, metal plate, and electrolysis negative electrode contact. The electrolysis control method is as follows: When the electrolysis atomizer activates its electrolysis function, the electrolysis enable voltage 1 is set high (this voltage only needs to fully conduct transistor Q3; it can be directly output by the main control chip, but the current-limiting resistors R8 and R9 must be properly selected, and the collector current Ic and base current Ib flowing through the transistor must satisfy the condition βmin ≥ 3Ic / Ib). This turns on the Q3 NPN transistor, pulls down the gate voltage of the Q2 nmos transistor, and turns Q2 on. The electrolysis negative electrode switch contact closes simultaneously, connecting the metal plate to ground. Voltage Ui, through the electrolysis circuit, electrolyzes the brine into hypochlorous acid. Current detection 2 monitors the electrolysis current in real time and accumulates the current value at regular intervals. When the accumulated value Si exceeds the set value 1 (this set value needs to be determined according to the actual current, voltage, and the capacity of the solution in the solution tank (such as brine), when the current, voltage, and solution tank capacity are determined, the set value is the accumulated current value from the time when the concentration of hypochlorous acid generated by electrolysis reaches the required concentration), the electrolysis enable voltage 1 is lowered, the NPN transistor Q3 is turned off, the gate voltage of the nmos transistor Q2 is set high, Q2 is turned off, and electrolysis is stopped.

[0081] Understandably, the requirement that Si should exceed the set value of 1 during electrolysis can be replaced by electrolysis for a period of time, and a hypochlorous acid detection sensor can be used instead. When the hypochlorous acid sensor detects that the concentration of hypochlorous acid is greater than a certain specific value, electrolysis is stopped.

[0082] That is, in the electrolytic atomizer provided by the present invention, power is supplied to the first and second electrolytic plates during the electrolysis stage to electrolyze saline solution to obtain disinfectant water, and power is supplied to the first and second electrode contacts based on the amount of solution in the solution chamber during the atomization stage to atomize and spray the disinfectant water. In other words, one device can realize the functions of electrolysis and spraying, eliminating the need to use an electrolysis device and a sprayer simultaneously as in the prior art. This alleviates the technical problem of high equipment cost caused by the need to use an electrolysis device and a sprayer simultaneously in the current electrolytic atomization technology.

[0083] Accordingly, this invention also provides a method for operating an electrolytic atomizer; in this embodiment, the electrolytic atomizer includes an electrolytic atomizing head and an electrolytic atomizer body. The electrolytic atomizing head includes a shell with a solution chamber, a vent hole, a first electrode contact and a first electrolytic plate disposed on a first side wall of the shell, a second electrode contact and a second electrolytic plate disposed on a second side wall of the shell, and an atomizing plate disposed on the second side wall; the first side wall and the second side wall are located on different sides of the solution chamber, and the atomizing plate is electrically connected to the second electrode contact; the electrolytic atomizer body includes an electrolytic atomization driving circuit; the electrolytic atomization driving circuit is electrically connected to the first electrode contact and the second electrode contact respectively; the operating method includes:

[0084] During the electrolysis stage, power is supplied to the first electrolytic plate and the second electrolytic plate through the electrolysis atomization drive circuit;

[0085] During the atomization stage, based on the amount of solution in the solution chamber, power is supplied to the first electrode contact and the second electrode contact through the electrolytic atomization drive circuit.

[0086] The following is combined Figure 5 , Figure 5 The working method of the electrolytic atomizer provided in the embodiments of the present invention will be described in terms of specific scenarios. Figure 5 A flowchart illustrating the working method of an electrolytic atomizer is shown; for example... ​ As shown, the working method of the electrolytic atomizer includes:

[0087] Step S501: Start the electrolysis function.

[0088] In this embodiment, when the switch of the electrolytic atomizer is turned on and the electrolysis function is activated, the electrolytic atomizer electrolyzes the solution in the solution chamber.

[0089] Step S502: Electrolysis enable voltage 1 is set high, and Q2 nmos transistor is turned on. The electrolysis negative switch contact is closed, and the metal plate is connected to ground.

[0090] In this embodiment, when the electrolytic atomizer activates its electrolysis function, the electrolysis enable voltage 1 is set high (this voltage only needs to be sufficient to fully turn on transistor Q3; it can be directly output by the main control chip, but the current-limiting resistors R8 and R9 must be properly selected, and the collector current Ic and base current Ib flowing through the transistor must satisfy the condition βmin≥3Ic / Ib). This turns on the NPN transistor Q3, pulls down the gate voltage of the nmos transistor Q2, and turns Q2 on. The electrolysis negative switch contacts close simultaneously, connecting the metal plate to ground.

[0091] Step S503: Electrolysis of the positive electrode generates electricity, with a voltage of Ui.

[0092] Step S504: An electrolytic circuit is formed between the electrolytic positive electrode and the atomizing metal sheet, and electrolysis is generated.

[0093] In this embodiment, voltage Ui electrolyzes the solution in the solution chamber through an electrolysis circuit. If the solution chamber contains saline solution, voltage Ui electrolyzes the saline solution into hypochlorous acid through the electrolysis circuit.

[0094] Step S505: Collect the current value of current detector 2 and accumulate it at regular intervals. The accumulated value is Si.

[0095] In this embodiment, the current detector 2 monitors the electrolysis current in real time and accumulates the current value at regular intervals. The accumulated value is represented by Si.

[0096] In some embodiments, the current value is accumulated at regular intervals. The period "at regular intervals" can be fixed or dynamic. When the solution volume in the solution tank is fixed, this period is also fixed. When this period is set to change dynamically, a water level sensor needs to be added to adjust the electrolysis time according to the amount of solution in the solution tank. When the solution volume is large, the electrolysis time is increased.

[0097] Step S506: Determine whether Si is greater than the set value 1.

[0098] In this embodiment, the set value 1 needs to be determined according to the actual current, voltage and the capacity of the solution (such as saline) in the solution chamber. When the current, voltage and solution chamber capacity are determined, the set value is the cumulative value of the current from the time when the concentration of hypochlorous acid generated by electrolysis reaches the required concentration.

[0099] In this step, if Si is greater than the set value 1, then step S507 is executed; if Si is not greater than the set value 1, then step S505 is executed.

[0100] Step S507: Set the electrolysis enable voltage 1 low, disconnect the Q2 nmos tube, electrolysis is complete, and wait for atomization to start.

[0101] In this embodiment, when Si is greater than the set value 1, the electrolysis enable voltage 1 is set low, the NPN transistor Q3 is turned off, the gate voltage of the nmos transistor Q2 is set high, Q2 is turned off, and electrolysis is stopped. The process then waits to proceed to the next stage of atomization.

[0102] Step S508: Turn on atomization.

[0103] This step follows the previous step; after electrolysis stops, atomization is turned on.

[0104] Step S509: PWM starts, Q1 nmos transistor generates high-frequency switching, and the electrolytic negative switch contacts open.

[0105] Step S510: Electrolysis of the positive electrode (atomizing the positive electrode contact) generates a high-frequency pulse voltage.

[0106] Step S511: The pulse voltage of the atomizing positive electrode contact is transmitted to the atomizing metal plate through the conductivity of the disinfectant.

[0107] In this embodiment, following the previous step, the pulse voltage is transmitted from the atomizing positive electrode contact to the atomizing metal plate through the conductivity of the disinfectant (i.e., hypochlorous acid generated by the electrolysis of saline solution).

[0108] Step S512: The atomizing plate vibrates at high frequency to form atomization.

[0109] Step S513: Determine whether the voltage monitored by voltage detection port 1 is greater than the set value 2.

[0110] In this embodiment, if the voltage detected by voltage detection port 1 is greater than the set value 2, it means that there is no solution in the solution chamber, so the PWM output is stopped and atomization is stopped, i.e., step S514 is executed; if the voltage detected by voltage detection port 1 is not greater than the set value 2, it means that there is still atomization solution in the solution chamber, so the process returns to step S512.

[0111] Step S514: Stop atomization.

[0112] That is, the working method of the electrolytic atomizer provided in this embodiment of the invention provides power to the first and second electrolytic plates during the electrolysis stage to electrolyze saline solution to obtain disinfectant water, and power to the first and second electrode contacts based on the amount of solution in the solution chamber during the atomization stage to atomize and spray the disinfectant water. In other words, one device can realize the functions of electrolysis and spraying, eliminating the need to use an electrolysis device and a sprayer simultaneously as in the prior art, thus alleviating the technical problem of high equipment cost caused by the need to use an electrolysis device and a sprayer simultaneously in the current electrolytic atomization technology.
