[0002] With the development of beauty technology, many skin problems can be improved through technological means. The most common method of skin care is to hydrate the skin. The traditional nano-atomization hydration atomizer is a portable new beauty tool. By using nano-technology, skin care water is introduced into it, and after atomization, it can quickly hydrate the skin, and the hydration effect exceeds that of ordinary facial masks. However, in the skin care water used by the traditional nano-atomization hydration atomizer, there are only a small amount of active substances.

If combined with the traditional atomizer and used as the water source of the atomizer, the advantages of both will be brought into play, more active substances will be produced, and the efficacy will be better.

The entire device includes a high-voltage electrode 1; an intake pipe 2; a gas buffer chamber 3; a ceramic atomization sheet 4; an activated water treatment chamber 5; a grounding electrode 6; a plasma discharge syringe 7; and an atomization chamber 8. The high-voltage electrode 1 is a metal electrode, which is a copper wire with a length of 25 mm and a diameter of 2 mm. The upper side of the copper wire is connected to an external power supply. The high-voltage electrode is connected in series with nine plasma discharge syringes. The series connection method is that the lower side 1.1 of its copper wire is electrically connected in series with the nine plasma discharge syringes. The number of intake pipes 2 is 3, the outer diameter is 4 mm, the inner diameter is 3 mm, and the height is 15 mm. The ceramic atomization sheet 4 is fixed on the side wall air pipe of the atomization chamber and sprays activated water by ultrasonic vibration.

[0020] Figure 3 is a schematic diagram of the core discharge structure of the device, including a high-voltage electrode 1, an intake pipe 2, a gas buffer chamber 3, and a plasma discharge syringe 7. The gas buffer chamber 3 is located below the intake pipe 2 and is interconnected with the intake pipe 2. The gas buffer chamber 3 is a quartz cylindrical hollow cavity, with an outer diameter of 20 mm, an inner diameter of 15 mm, and a height of 30 mm.

[0021] Figure 4 is a schematic diagram of the structure of the plasma discharge syringe 7, which is composed of a discharge metal wire 7.1 and a quartz tube 7.2. The discharge metal wire 7.1 is a solid copper wire structure, with a length of 100 mm and a diameter of 1 mm. A quartz tube 7.2 is sleeved outside the plasma discharge metal wire. The quartz tube is 60 mm long, with an outer diameter of 3 mm and an inner diameter of 2 mm. The discharge metal wire 7.1 is embedded in the quartz tube 7.2 and exposed on the upper side. The length of the metal wire protruding from the quartz tube on the upper side is 40 mm. There are nine plasma discharge syringes 7, arranged in three rows and three columns, with a mutual spacing of 5 mm.

[0022] Figure 5 It is a schematic structural diagram of the grounding electrode 6, which is composed of a metal electrode 6.1 and a leak-proof plug 6.2. The grounding electrode 6 is inserted into the bottom side of the activated water treatment chamber 5. The metal electrode 6.1 is a copper wire with a length of 50 mm and an outer diameter of 2 mm.

[0023] The device uses a special plasma power supply, which outputs an AC or pulsed voltage with a frequency of 5 - 30 kHz and a voltage of 5 - 10 kV. The high-voltage electrode 1 is connected to the positive pole of the special plasma discharge power supply and is electrically connected to the discharge metal wire 7.1 of the plasma discharge needle tube 7. The plasma discharge needle tube 7 is inserted into the skin care water to be treated. The metal electrode 6.1 of the grounding electrode 6 is inserted into the bottom side of the activated water treatment chamber 5, its outer end is connected to the negative pole of the special plasma power supply, and its inner end is exposed and inserted into the skin care water to be treated. When the plasma discharge power supply acts, a high-voltage electric field will be formed between the plasma discharge metal wire needle tube 7 and the metal electrode 6.1, generating dielectric barrier discharge and arc discharge.

[0024] Working principle: The skin care water to be processed is filled into the activated water treatment chamber 5; the dedicated plasma power supply powers the device, and the device is in the working state; different gases can enter the gas buffer chamber 3 through different intake pipes 2 by means of an external air pump. The gases can be oxygen, air, helium and other gases. The diameter of the discharge metal wire is 1 mm, and the diameter of the quartz dielectric tube is 2 mm, and there is a discharge space. After the gases are mixed, they enter the discharge space of the quartz hollow cylinder 7.2. The discharge metal wire 7.1, the skin care water, and the side wall of the quartz hollow cylinder 7.2 form a dielectric barrier discharge, initially generating dielectric barrier discharge plasma. The gas mixture of the plasma enters the skin care water in the activated water treatment chamber 5, generating a large number of bubbles. The discharge metal wire 7.1 retracts into the interior of the quartz hollow cylinder 7.2 and will not leak out of the quartz tube to contact the liquid. The bottom end of the discharge metal wire 7.1 is 3-5 mm away from the bottom end of the quartz hollow cylinder. When bubbles are generated, under the action of the high voltage applied by the plasma power supply, a high-voltage electric field is formed between the bottom end of the discharge metal wire 7.1 and the liquid between the plasma discharge needle tube and the metal electrode 6.1, and gas arc discharge will be generated in the bubbles, further generating richer low-temperature plasma and increasing the types of active particles inside the low-temperature plasma. Since the gas in the bubbles is a gas mixture of plasma, arc discharge will be more likely to occur and the discharge will be more intense and effective. This device combines dielectric barrier discharge and bubble discharge, which is a hybrid discharge. The generated low-temperature plasma contains more active particles, richer strongly oxidizing hydroxyl radicals, richer high-energy radical groups, etc., such as hydrogen peroxide, ozone, etc. Hydrogen peroxide and ozone have the functions of sterilization, disinfection, and purification. Spraying the activated water generated by the plasma on the skin can sterilize, remove mites, whiten, purify and promote blood circulation of the human skin, and activate cells. The gas can enter the activated water treatment chamber through three intake pipes 2 arranged in a triangular pattern, so the function of gas mixing can be realized; the device can rapidly and efficiently generate plasma-activated water in situ, and directly spray the generated activated water through a ceramic atomization sheet by using ultrasonic vibration. The device is combined together to realize the integration of plasma discharge and atomization.

[0025] The consistency of the needle tube length and the equal spacing between two needle tubes can ensure uniform discharge, thus ensuring the uniformity of the plasma entering the wastewater purification area. The discharge effect can be enhanced by changing the number of discharge needle tubes; the discharge effect of the plasma can also be changed by changing the gas introduced into the gas buffer area.

[0026] Finally, it should be noted that although the present invention has been described through preferred embodiments, the present invention is not limited to the embodiments described herein. Various changes and variations are also included without departing from the scope of the present invention.
