Referring to fig. 1, in an embodiment of the present application, a plasma activated water preparing apparatus 100 is provided, which includes a water tank 10 and an electrode assembly 30, wherein the water tank 10 has an accommodating cavity 11, and the electrode assembly 30 is mounted on the water tank 10 and extends into the accommodating cavity 11 for generating plasma through discharge, so that the plasma is mixed with water in the water tank 10 to react, and generate substances such as peroxynitrous acid, hydrogen peroxide, nitric acid, nitrous acid and the like having anticancer and bactericidal functions, so as to prepare plasma activated water.
In some embodiments, electrode assembly 30 includes a first electrode assembly 32 and a second electrode assembly 34 both mounted to tank 10, with first electrode assembly 32 extending at least partially into tank 10 and arcing with the liquid in tank 10, and second electrode assembly 34 extending at least partially into tank 10 and glowing. In this way, the plasma generated by glow discharge of the second electrode assembly 34 can be mixed with the water in the water tank 10 to generate a large amount of active particles to prepare plasma-activated water. Further, arc discharge is performed between the first electrode assembly 32 and the liquid in the water tank 10 to generate hydrogen peroxide with a high concentration, thereby increasing the content of hydrogen peroxide in the liquid in the water tank 10, lowering the PH, and increasing the sterilization rate of the plasma-activated water.

When preparing the plasma activated water, the first substrate 321 at least partially extends into the liquid carried in the accommodating chamber 11, that is, at least partially extends into the water in the accommodating chamber 11, and the liquid in the first discharge chamber 322 is discharged by supplying air to the first discharge chamber 322, so as to prevent the water from entering the first discharge chamber 322.
And, after the air is supplied into the first discharge chamber 322, the bottom of the first substrate 321 is forced to form a low liquid level, which is lower than the main liquid level of the liquid in the water tank 10 and is located at the bottom of the first substrate 321. In addition, the first electrode 325 is controlled to generate an arc between its end and the low level liquid surface, so that the arc between the end of the first electrode 325 and the low level liquid surface is generated by the high-voltage discharge of the first electrode 325 in the first discharge chamber 322. Thus, the first electrode assembly 32 generates hydrogen peroxide with a high concentration through the arc discharge mode, thereby effectively improving the sterilization efficiency of the plasma activated water.

In practical use, the air flow can be conveyed to flow towards the first air inlet hole, then the air flow flows out from the first air outlet hole after flowing through the first discharge cavity 322, and the liquid at the bottom of the first base 321 is blown away in the flowing-out process to form a low-level liquid level. In addition, the first electrode 325 is communicated with the low-level liquid surface through the first air outlet, and can generate electric arc between the end part of the first electrode and the low-level liquid surface after high pressure is applied, so that high-concentration hydrogen peroxide is formed, and the sterilization efficiency is improved.

In this way, the activated water is prepared by performing not only arc discharge by the first electrode assembly 32 but also glow discharge by the second electrode assembly 34, thereby increasing the content of active particles in the water tank 10 and improving the efficiency of preparing plasma activated water.
Referring to fig. 3, optionally, the second electrode assembly 34 further includes an insulating film 347, the second electrode 345 has a free end located in the second discharge chamber 342, and the insulating film 347 covers at least a tip and/or a depression of an outer surface of the free end to prevent arc discharge from occurring at the tip and the depression of the free end to affect the efficiency of glow discharge, thereby ensuring the efficiency of preparing plasma activated water.
Further, a second air inlet hole and a second air outlet hole which are communicated with the second discharge cavity 342 are formed in the second base 341.
