Specifically, in the step of adjusting the gas regulating valve 300 by the processor 200, when the gas flow signal is greater than the set gas flow range, the processor 200 decreases the gas regulating valve 300; when the gas flow signal is less than the set gas flow range, the processor 200 adjusts the gas regulator valve 300.

Alternatively, in this embodiment, as shown in fig. 1 and 2, the sensing assembly may include a pressure sensor 500, and the pressure sensor 500 is mounted to the first connection pipe 930 for sensing the pressure of the fluid in the first connection pipe 930. The fluid in the first connection pipe 930 is a mixed fluid of air and water that is mixed and pressurized by the self-priming pump 100, and the pressure sensor 500 is used for detecting the pressure of the mixed fluid; when the sensing assembly includes the pressure sensor 500, the flow boost amount adjustment step may include: the pressure sensor 500 transmits the pressure signal of the mixed fluid to the processor 200, the processor 200 compares the received pressure signal with a set fluid pressure range, and if the pressure signal is within the set fluid pressure range, the self-priming pump 100 does not need to be adjusted; if the pressure signal is outside the set fluid pressure range, the processor 200 adjusts the amount of pressure boost of the self-primer pump 100, the pressure sensor 500 transmits the adjusted pressure signal to the processor 200, the processor 200 compares again, and so on until the pressure signal is within the set fluid pressure range.

Additionally, as shown in fig. 2, the processor 200 may include a control module 210 and a PWM (Pulse Width Modulation) timing module, the detection component transmits the fluid pressurization amount signal to the control module 210, and the control module 210 adjusts the pressurization amount of the self-primer pump 100 through the PWM timing module 220.

It should be noted that the mixed fluid entering the micro-nano bubble preparation device needs to satisfy two conditions: the volume ratio of air to water in the mixed fluid and the pressure of the mixed fluid, namely, the relevant factors are the air flow input by the air pipe 920, the water flow input by the liquid inlet pipe 910 and the fluid pressure after the air and the water are mixed, and when the three factors are all in the set range, the obtained mixed fluid meets the requirements; wherein, the pressure of mixed fluid receives air flow, the influence of discharge and self priming pump 100 pressure boost volume simultaneously, because self priming pump 100 provides power and as the pressure boost source of mixed fluid for static water simultaneously, namely, the pressure boost volume of self priming pump 100 simultaneously to the discharge in feed liquor pipe 910 and mixed fluid's pressure production influence, mixed fluid's pressure is relevant with the discharge of feed liquor pipe 910, consequently when mixed fluid's pressure is in setting for the within range, show that air flow and discharge also are in corresponding settlement within range simultaneously, this mixed fluid inputs the micro-nano bubble water that can make high-quality among the micro-nano bubble preparation facilities. Similarly, when the air flow and the water flow are simultaneously in the set range, the pressure of the mixed fluid formed by the air and the water is also in the set range, and the mixed fluid is input into the micro-nano bubble preparation device to prepare high-quality micro-nano bubble water.

In this embodiment, the detection assembly may include both the pressure sensor 500 and the liquid flow meter 600, or only one of them.

Therefore, when the detection assembly includes the pressure sensor 500, the micro-nano bubble preparation apparatus may be prepared as follows: starting the self-priming pump 100 and the gas regulating valve 300, the self-priming pump 100 pumps liquid into the liquid inlet pipe 910 and flows to the self-priming pump 100; the gas flows into the gas transmission pipe 920 through the gas regulating valve 300, enters the liquid inlet pipe 910 and flows into the self-priming pump 100 together with the liquid in the liquid inlet pipe 910; the gas and liquid entering the self-priming pump 100 are mixed and pressurized by the self-priming pump 100 to form a mixed fluid, and the mixed fluid enters the first connecting pipe 930.

The pressure sensor 500 transmits the pressure signal of the mixed fluid to the processor 200, the processor 200 compares the received pressure signal with a set fluid pressure range, and if the pressure signal is within the set fluid pressure range, the self-priming pump 100 and the gas regulating valve 300 do not need to be adjusted; the mixed fluid in the first connection pipe 930 enters the micro-nano bubble generating assembly 800 to obtain micro-nano bubble liquid.

And if the pressure signal is out of the set fluid pressure range, carrying out gas flow regulation: the gas flow meter 400 transmits a gas flow signal in the gas pipe 920 to the processor 200, the processor 200 compares the received gas flow signal with a set gas flow range, and if the gas flow signal is in the set gas flow range, the gas regulating valve 300 does not need to be regulated; if the gas flow signal is outside the set gas flow range, the processor 200 adjusts the gas regulating valve 300, the gas flow meter 400 transmits the adjusted gas flow signal to the processor 200, the processor 200 compares again, and the process is repeated until the gas flow signal is within the set gas flow range. After the gas flow is adjusted, the pressure sensor 500 transmits a pressure signal of the mixed fluid to the processor 200, the processor 200 compares the received pressure signal with a set fluid pressure range, if the pressure signal is within the set fluid pressure range, the pressure signal indicates that the gas flow, the liquid flow and the pressure of the mixed fluid meet the requirements, and the mixed fluid in the first connecting pipe 930 enters the micro-nano bubble generating assembly 800 to obtain micro-nano bubble liquid; if the pressure signal is outside the set fluid pressure range, the processor 200 adjusts the pressurization amount of the self-priming pump 100, the process adjusts the fluid flow rate and the pressure of the mixed fluid at the same time, the pressure sensor 500 transmits the adjusted pressure signal to the processor 200, the processor 200 compares the pressure signal again, and the process is circulated until the pressure signal is within the set fluid pressure range, which indicates that the gas flow rate, the liquid flow rate and the pressure of the mixed fluid all meet the requirements; the adjusted mixed fluid in the first connection pipe 930 enters the micro-nano bubble generating assembly 800 to obtain micro-nano bubble liquid.

In the preparation method, the pressure of the mixed fluid is detected and judged, and when the pressure is in a set range, the mixed fluid meets the requirement, and other detection and adjustment are not needed; when the pressure is out of the set range, the gas flow rate and the fluid pressurization amount are adjusted. Compared with the first preparation method, the preparation method needs to adjust the gas flow and the fluid pressurization amount, and the adjustment process of the preparation method is simpler and more convenient.

Specifically, in the adjusting step of the gas regulating valve 300 by the processor 200, when the pressure signal is greater than the set fluid pressure range, the processor 200 regulates the gas regulating valve 300; when the pressure signal is less than the set fluid pressure range, the processor 200 decreases the gas regulator valve 300. In the step of adjusting the pressurization amount of the self-priming pump 100 by the processor 200, when the pressure signal is greater than the set fluid pressure range, the processor 200 decreases the pressurization amount of the self-priming pump 100; when the pressure signal is less than the set fluid pressure range, processor 200 adjusts the amount of pressurization from primer pump 100.

It should be noted that, the "gas flow signal", "fluid pressurization amount signal", "pressure signal" and "liquid flow signal" all refer to corresponding values represented by the signals, for example, "gas flow signal is compared with a set gas flow range" refers to a value represented by the gas flow signal is compared with a set gas flow range.
