The micro-nano bubbles refer to bubbles with the diameter of 0.1-50 mu m, and the bubbles have different physical and chemical properties from common bubbles. The micro-nano bubbles are very small in size, and the surface tension of the micro-nano bubbles is very low, so that O2 molecules and water molecules are more easily combined. Because the diameter of the micro-nano bubbles is very small, the micro-nano bubbles can easily permeate into pores and take away dirt in the pores; meanwhile, when a large number of bubbles are dissolved in water and broken, high-energy ultrasonic waves are generated, and a large number of oxygen anions are generated. The bubble water has the effects of sterilizing, improving human immunity, improving allergic constitution, purifying skin, moistening and moisturizing and the like because the bubble water has negative charges and hydroxyl free radicals with strong oxidizing property and ultrahigh oxidation-reduction potential.

However, the water source connected to the water heater of the user has pressure, and when the water pressure is higher, the air dissolving process is more difficult, the generated micro-nano bubble water has poor and unstable effect, mainly expressed by large size and low concentration of the bubble water, and the real effect of the micro-nano bubble water is difficult to be exerted.
