Embodiment Construction

[0015] see figure 1 with figure 2 , is a handheld L-shaped housing, including a cylindrical housing 100 and a cylindrical handle 111, a layer of shielding net 110 is provided on the inner wall of the housing 100, and a high-voltage power supply 103 is provided in the housing 100 And an insulating medium tube 102 with one end sealed and the other end open, the closed end of the insulating medium tube 102 is exposed at the position A indicated by the opening 108, which is the position in contact with human skin.

[0016] A high-voltage electrode 101 is covered in the insulating medium tube 102. The high-voltage electrode 101 and the insulating medium tube 102 together form a coated electrode. The high-voltage electrode 101 is made of metal powder, and an insulating material sheet 105 is used to block the insulating medium tube. 102 to seal the metal powder in the tube, a metal disc 104 is arranged in the electrode 101, a wire 106 connects the metal disc 104 and the high-voltag...

Abstract

The invention discloses a cold plasma discharger. The cold plasma discharger is characterized by comprising a hand-held housing, the housing is provided with a control switch, the inner wall of the housing is provided with a metal shield net layer, the housing is internally provided with a power supply and an electrode (hereafter referred to wrapped electrode for short) wrapped by an insulation medium, the wrapped electrode is installed at one end portion of the housing, and the other end of the housing is provided with a power supply lead wire plug. When human skin approaches or contacts the wrapped electrode at the end portion of the housing, cold plasma discharge is generation between the human skin and the wrapped electrode. The cold plasma discharger has the effects of sterilization and disinfection for human skin surface.

Description

【Technical field】 [0001] The invention relates to a new type of cold plasma discharge instrument, especially a medium-high-frequency high-voltage power supply and an insulating medium tube with one end closed in a hand-held housing. When the human skin approaches or touches the coated electrode, cold Plasma instruments. 【Background technique】 [0002] Plasma is generally generated between two electrodes, and the gas between the electrodes is broken down and ionized to form plasma. Plasma is an ionized gas that contains a large number of electrons, ions and free radicals, and is electrically neutral to the outside. Due to the unique physical and chemical properties of plasma, plasma can be used to modify the surface of objects. Cleaning, grafting of new materials, and surface sterilization. Experiments have also proved that bacteria can be quickly killed by plasma discharge. When the discharge power is relatively small (such as less than 20 watts), the temperature of the pl...
