[0038] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Example 1

[0040] like Figures 1 to 3 As shown, the present invention provides an ozone generating circuit, which includes a power supply VCC, a boost module 1, an ozone generator 2, and a control module 3.

[0041] Specifically, in this embodiment of the invention, the power supply VCC is used to power the ozone generator 2. The input terminal of the boost module 1 is connected to the power supply VCC. When the boost module 1 is working, it boosts the voltage output by the power supply VCC and provides the boosted high voltage to the ozone generator 2 through the output terminal of the boost module 1. When the boost module 1 is not working, the power supply VCC normally powers the ozone generator 2. The ozone generator 2 is provided with a positive terminal and a negative terminal. The positive terminal is connected to the output terminal of the boost module 1, and the negative terminal is grounded.

[0042] Furthermore, the control module 3 is connected to the control terminal of the boost module 1 and is used to control the start and stop of the boost module 1. The control module 3 is also provided with a voltage detection terminal, which is connected to the ozone generator 2. The control module 3 can use the voltage detection terminal to detect whether the operating voltage of the ozone generator 2 is lower than a preset voltage.

[0043] Specifically, when using ozone generator 2 for ozone disinfection, it first enters an over-power operation phase. During this phase, the boost module 1 is activated via control module 3. Boost module 1 increases the output voltage of the power supply and then inputs the increased voltage to ozone generator 2. Under this high-voltage drive, ozone generator 2 rapidly generates high voltage, enabling it to quickly enter operating mode and generate ozone. Using a fan in conjunction with ozone generator 2 accelerates air convection, allowing more airborne adsorbents to come into contact with the ozone, thus improving its disinfection efficiency.

[0044] After the boost module 1 has been running for a first preset period of time, the actual operating voltage of the ozone generator 2 is detected by the voltage detection terminal of the control module 3 to determine whether the actual operating voltage of the ozone generator 2 is lower than the preset voltage. When the actual operating voltage of the ozone generator 2 is lower than the preset voltage, it indicates that there are still a large number of fine impurities on the surface of the ozone generator 2. These impurities are still affecting the original electrical structure of the ozone generator 2, directly affecting the intensity of the ozone generator 2 during operation, thus resulting in a lower actual operating voltage and a reduced ozone generation rate. Therefore, it is necessary to put the ozone generator 2 back into the high-power operation stage and continue to drive it with high voltage.

[0045] If, after running for the first preset time, the actual operating voltage of ozone generator 2 is equal to or higher than the preset voltage, it indicates that the fine impurities on the surface of ozone generator 2 have been removed, and no impurities are affecting the original electrical structure of ozone generator 2. In this case, the control module 3 stops the boost module 1 from operating, and the power supply VCC normally supplies power to ozone generator 2. At this time, ozone generator 2 can operate normally and produce ozone under this driving voltage state, while simultaneously reducing energy consumption and achieving optimal ozone conversion.

[0046] With this configuration, the circuit can output two voltages, enabling the milk sterilizer to operate at different power levels during different working stages. This effectively increases ozone production, reduces the impact of insufficient start-up of the ozone generator 2 during long-term cyclic use on performance, and ensures that consumers can use the milk sterilizer normally for effective sterilization after long-term use. This extends the product's lifespan and also gains the long-term trust of users.

[0047] Further, in an optional embodiment of the invention, the boost module 1 includes an inductor L and a switching circuit. Specifically, one end of the inductor L is connected to the power supply VCC, and the other end of the inductor L is connected to the positive terminal of the ozone generator 2, so that the other end of the inductor L can provide the boosted voltage to the ozone generator 2. The control terminal of the switching circuit is adapted to receive a control signal, the first terminal of the switching circuit is connected to the other end of the inductor L, and the second terminal of the switching circuit is grounded. Under the action of the control signal, the first and second terminals of the switching circuit can be connected and cut off.

[0048] Specifically, the switching circuit may include a switching transistor Q1, a first resistor R1, and a second resistor R2. The control terminal of the switching transistor Q1 is adapted to receive the control signal. The first terminal of the switching transistor Q1 is connected to one end of a current-limiting resistor R4, and the other end of the current-limiting resistor R4 is connected to the other end of the inductor L. The second terminal of the switching transistor Q1 is grounded. When the first resistor R1 is included in the switching circuit, one end of the first resistor R1 can be connected to the control terminal of the switching transistor Q1, and the other end of the first resistor R1 is adapted to receive the control signal. One end of the second resistor R2 is connected to the control terminal of the switching transistor Q1, and the other end of the second resistor R2 is grounded.

[0049] In actual operation, when using ozone generator 2 for ozone disinfection, it first enters the high-power operation phase. During this phase, the control module 3 sends a control signal, which can be a square wave of a certain frequency. Then, under the continuous switching action of the switching transistor Q1, the inductor L increases the voltage output from the power supply VCC, and the increased voltage is then input to the ozone generator 2. Under this high-voltage drive, the ozone generator 2 quickly enters its working state, and the ozone generation section rapidly produces ozone.

[0050] After the boost module 1 has been running for a first preset time, the first preset time is... Figure 2 During time T1, the actual operating voltage of ozone generator 2 is detected by the voltage detection terminal of control module 3 to determine whether the actual operating voltage of ozone generator 2 is lower than the preset voltage. When the actual operating voltage of ozone generator 2 is lower than the preset voltage, it indicates that there are still a large number of fine impurities on the surface of ozone generator 2. These impurities are still affecting the original electrical structure of ozone generator 2, directly affecting the intensity of ozone generator 2 during operation, thus resulting in a lower actual operating voltage of ozone generator 2 and consequently reducing the ozone generation rate. Therefore, it is necessary to put ozone generator 2 back into the high-power operation stage and continue to drive it with high voltage.

[0051] If, after running for the first preset time, the actual operating voltage of ozone generator 2 is equal to or higher than the preset voltage, it indicates that the fine impurities on the surface of ozone generator 2 have been removed, and no impurities are affecting the original electrical structure of ozone generator 2. Then, it runs for the second preset time. The second preset time is... Figure 2 During time T2, the control signal from control module 3 is low. For the second preset duration, control module 3 continuously outputs a low-level signal, thereby turning off switch Q1. The power supply VCC normally powers the ozone generator 2. The current flowing through inductor L remains constant. At this time, ozone generator 2 can normally generate ozone under this driving voltage state, while simultaneously reducing energy consumption and achieving optimal ozone conversion.

[0052] Further, in an optional embodiment of the invention, the control module 3 includes a third resistor R3 and a controller 4. Specifically, one end of the third resistor R3 is connected to the negative terminal of the ozone generator 2, and the other end of the third resistor R3 is grounded. The controller 4 is electrically connected to the boost module 1, and the controller 4 is provided with a voltage detection terminal and a signal output terminal. The voltage detection terminal is connected to the negative terminal of the ozone generator 2, and the signal output terminal is connected to the control terminal of the boost module 1. The controller 4 sends the control signal to the boost module 1 through the signal output terminal.

[0053] Furthermore, in an optional embodiment of the invention, the ozone generating circuit further includes a rectifier and filter module 5. One end of the rectifier and filter module 5 is connected to the output terminal of the boost module 1, and the other end of the rectifier and filter module 5 is connected to the positive terminal of the ozone generator 2.

[0054] Specifically, the rectifier-filter module 5 includes a rectifier diode D and a filter capacitor C. In this embodiment of the invention, the anode of the rectifier diode D is connected to the output terminal of the boost module 1, and the cathode of the rectifier diode D is connected to the positive terminal of the ozone generator 2. One end of the filter capacitor C is connected to the cathode of the rectifier diode D, and the other end of the filter capacitor C is grounded.

[0055] The rectifier and filter module 5 can make the voltage of the ozone generator 2 more stable, allowing the ozone generator 2 to work continuously.

[0056] Furthermore, in this embodiment of the invention, the circuit uses common, inexpensive materials such as resistors, transistors, and capacitors, resulting in a very low overall cost while achieving the effect of controlling different operating states of the ozone generator 2. Additionally, any resistor can be replaced by multiple resistors connected in series, parallel, or in a series-parallel configuration; the inductor L can also be replaced by materials with inductive components; and the switching transistor Q1 can be a transistor, or other switching transistors such as MOSFETs can be used instead.

[0057] Of course, this embodiment is merely an example of a specific electronic component, but it is not intended to limit the scope of the invention. Those skilled in the art can make changes according to the actual situation, as long as the same technical effect can be achieved.

[0060] This configuration allows the milk sterilizer to output two voltages via its ozone generation circuit, enabling different power levels at different operating stages. This avoids the impact of adsorbed particulate matter and other impurities on the surface of ozone generator 2 on ozone production, effectively eliminating the influence of airborne impurities on the sterilizer's performance. It also significantly increases ozone production and reduces the impact of insufficient start-up from ozone generator 2 during prolonged use, ensuring that consumers can use the sterilizer normally for effective sterilization even after long-term use. Simultaneously, it extends the sterilizer's lifespan, guaranteeing long-term use, improving user experience, and increasing customer trust in the brand.
