[0033] The present invention will be further explained below in conjunction with the drawings. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. In addition, it should be understood that after reading the teachings of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of this application.
[0034] figure 1 Shows a structural diagram of an embodiment of the present invention. A plasma comb for treating the scaly layer on the surface of human hair and improving the characteristics of the scaly layer to dye and comb the hair. The plasma comb includes a positive comb plate 100, a negative comb plate 200, a positive comb 102, and a negative comb Tooth 202, wires, switch and voltage regulating device 400, power supply (not shown) and housing 300. Among them, the positive comb teeth 102 are fixed on the positive comb plate 100, the negative comb teeth 202 are fixed on the negative comb plate 200, the positive comb plate 100 and the negative comb plate 200 are stacked up and down and placed in the housing 300. Of course The positive comb plate 100 and the negative comb plate 200 can also be placed side by side. The positive comb plate 100 is placed on the negative comb plate 200, and the comb teeth 202 fixed on the negative comb plate 200 pass through the positive comb plate 100 so as to be parallel to the 102 comb teeth fixed on the positive comb plate 100. . The positive comb teeth 102 and the negative comb teeth 202 are adjacent to each other, pass through the housing 300, and are respectively connected to the positive and negative electrodes of the power supply, so as to serve as discharge electrodes. The power supply can provide a positive high voltage to the positive comb tooth 102 and a negative high voltage to the negative comb 202 through the switch and voltage regulating device 400. The positive high voltage and the negative high voltage are equal in magnitude and opposite in direction. In addition, the housing 300 can be made into a breathable structure: vent holes are added between the comb teeth, and other gases or mixed gases such as helium, argon, etc. can be passed into the comb, so that the discharge generates different plasmas, which can also be used for processing Hair different from human hair. The distance between the comb teeth is about 1 mm, which can keep the discharge voltage low and at the same time ensure that the hair can pass the comb teeth smoothly.
[0035] In this embodiment, after the positive and negative comb teeth are respectively connected to the positive and negative electrodes of the power supply, a potential difference is generated between the comb teeth, so that the air discharge between them generates plasma, which acts on the surface of the hair during the process of combing the hair, and realizes the effect on the hair. Treatment of scale layer. The switch and voltage adjusting device 400 can control and adjust the connection and disconnection between the positive comb teeth 102 and the negative comb teeth 202 and the power supply, and adjust the potential difference between the positive comb teeth 102 and the negative comb teeth 202 to adapt to different temperatures, Environmental conditions such as humidity and different plasma intensity requirements in applications. The plasma comb may have a single-row comb, and the voltage polarity of every two adjacent comb teeth is opposite, and plasma is generated between each two comb teeth; it may also be a multi-row comb, each two adjacent rows The voltage polarity of the comb teeth connection is opposite, and plasma is generated between every two rows of comb teeth. The power supply can be a power supply placed on the plasma comb or an external power supply. The power supply type can be a bipolar sinusoidal power supply or a pulse power supply, which is safer than a DC power supply.
[0036] See below figure 2 , Which is the shape of the comb plate seen when looking down on the plasma comb. Separate the comb plates that are placed on top of each other and figure 2 Place them side by side like that. The positive comb plate 100 is provided with a gap 103, and is provided with a positive lead 101 and a positive comb 102. The positive comb 102 is connected in series by the positive lead 101. Of course, the positive comb can also be connected in other ways, such as parallel, or Mixed in series and parallel. The negative comb plate 200 is provided with a negative lead 201 and a negative comb 202. Similarly, the negative comb 202 is connected in series via the negative lead 201, and the negative combs can also be connected in other ways, such as parallel or series-parallel hybrid. When the positive comb-tooth plate 100 and the negative comb-tooth plate 200 are stacked up and down, the negative comb teeth 202 are just inserted into the gap 103, so that the positive comb teeth and the negative comb teeth are arranged apart. The gap 103 can be replaced by a hole. Moreover, there may be only one comb plate, and the positive comb teeth and the negative comb teeth are placed adjacently on the comb plate at the same time. The positive comb tooth 102 is connected to the positive electrode of the power supply through the switch and voltage regulator 400, and the negative comb tooth plate 200 is connected to the negative electrode of the power supply through the negative lead 201. At this time, the positive comb tooth 102 is connected to the negative comb tooth. The potential on 202 is equal and reversed. There is a potential difference between the positive comb teeth 102 and the negative comb teeth 202. The voltage adjustment device can control the magnitude of the potential difference. When there is a slight current sound and the smell of ozone is generated, it indicates that the air has begun to discharge , And generate plasma.
[0037] Reference below image 3 , The left image is a partial enlarged view of the right image during use. The bipolar discharge voltages of equal magnitude and opposite direction are used on the comb teeth of the plasma comb. When the gap potential difference remains unchanged, the potential difference between the comb and the scalp is doubled, and when combing, the positive comb teeth and the negative electrode There is a potential difference in the comb teeth, which makes the tiny current on the scalp form a local microcirculation (the arrow in the figure shows the direction of the current), which will not go deep under the scalp cortex, and will not affect the brain nerves, which is safe for the human body.
[0038] After the plasma is generated between the positive comb teeth and the negative comb teeth, use the plasma to comb the hair. When the hair passes through the gap between the comb teeth, the plasma will act on the hair surface to etch the scale layer on the surface of the hair fiber. On the one hand, plasma oxidation can break the strong hydrophobic cystine structure in the hair fiber, and introduce a large number of hydrophilic active groups on the surface of the hair fiber to improve the hydrophilic properties of the hair fiber. On the other hand, , The plasma etching of the hair fiber scaly layer also breaks the diffusion barrier of the dye on the surface of the hair and improves the rate of the dye on the fiber. As a result, the surface treatment of the hair is realized, which is convenient for dyeing the hair again without causing harm to the human body.

At the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation and scope of application. In summary, the content of this specification should not be construed as limiting the present invention.
