It should be noted that after the electrolysis of the mouthwash electrolysis component 400 , superoxide mouthwash is produced, the main components of which are ozone and hypochlorous acid.

As shown in Figure 1, on the basis of the above-mentioned embodiment, it also includes at least a temperature sensor 930 and a sensor capable of collecting current, and the sensor capable of collecting current may be a current collector arranged in the circuit formed by the control assembly And it is used to directly collect the current passing through the electrolytic sheet during the electrolysis process, and the current collector can also be replaced by a TDS sensor, and the TDS sensor is directly arranged in the preparation box 200, and the data measured by the TDS sensor is combined with the data of the temperature sensor.

In terms of working principle, the ozone concentration sensor 910 can only detect the concentration of ozone in the air, and the concentration of ozone in the mouthwash is actually calculated by a sensor capable of collecting current and various data detected by the temperature sensor 930 .

At present, most of the ozone concentration detectors on the market are expensive electronic ozone concentration detectors, which are large in size, so they are not suitable for this device. The ozone concentration sensor 910 can initially detect the concentration of ozone, avoid ozone overflow, and prevent the loss of ozone in mouthwash. The concentration is deduced by the temperature sensor 930 and the current collector according to the algorithm. It detects the concentration of ozone in the mouthwash after a certain period of electrolysis, so as to judge the production efficiency of the ozone concentration in the current environment.

As shown in Figure 1 and Figure 5, on the basis of the above-mentioned embodiment, a liquid level detection module is also provided, so that the control component executes the corresponding electrolysis time according to the water level in the preparation tank to generate mouthwash with preset ozone concentration.

One of the detection methods includes three metal probes and a data acquisition chip. The metal probes are vertically arranged in the preparation box 200.

When the water level in the water tank drops to the point that it cannot be sensed by the three metal probes, it is equivalent to disconnecting all of them, the second pin and the sixth pin of the chip U2 are at low level, and the third pin OUTPUT port output of the chip U2 is high level.

When the water level connects the contacts of the COM end and the LOW end, because the second pin is also low level, the second pin and the sixth pin of the chip U2 remain low level, and the third pin OUTPUT port of the chip remains output high level. When the water level rises to the high water level HIGH, because the HIGH terminal is high level, the COM terminal and the LOW terminal are both high level, the second pin and the sixth pin of the chip U2 become high level, and the chip U2 The third pin output is low level.

When the water level drops below the low water level, the liquid level detection module will send a signal to the control assembly, and the control assembly will control the first water pump 210 to feed water into the preparation tank 200, and when the water level is high, the liquid level detection module will send a signal to the The control component controls the first water pump 210 to stop water feeding into the preparation tank 200 by the control component.

Preferably, another detection method is that two liquid level sensors are vertically arranged on the outer wall of the preparation tank (not shown in the figure), and the liquid level sensor is a photoelectric liquid level sensor. When the water level is flush with the liquid level sensor , the control module can obtain the current water level in the preparation tank.

The liquid level detection module 920 can sense the water level in the preparation tank 200, and when the water level in the preparation tank 200 reaches the set water level, the ozone water electrolysis component 400 is automatically activated for electrolysis.

After making mouthwash many times, analyze the best ozone water production environment (including temperature and current value) under the current situation through PID parameters, and configure the best environment (constant temperature and constant pressure) through corresponding adjustments. At the same time, keep the PID parameter value, record the limit value of ozone dissolution, judge whether the current ozone concentration continues to rise through the change of the internal environment, and prevent the ozone concentration from escaping.

Due to the differences in water quality, temperature and pressure in various places, the ozone water concentration algorithm will perform data learning on the stable values provided by the ozone concentration sensor 910 to ensure the reliability of the fitted ozone water concentration.

What needs to be added here is that a temperature regulating plate can also be provided in the preparation box 200, the temperature regulating plate is electrically connected with the control component, and the temperature regulating plate is controlled by the temperature sensor 930 to keep the inside of the preparation box at a constant temperature.
