Problems solved by technology

According to the article mentioned above, in order to prevent plasma filamentation, ignition sparks and gas thermalization, such equipment must use inert gases such as helium as the working gas. conducive to practical application
A gas with helium, in order for the device to generate a diffuse atmospheric pressure plasma, but using a lot of helium besides being expensive, it also limits the range of operation of the device
For example, in order to further prevent the operating gas from heating and sparking, the generation of the plasma must be in a large flow of working gas, which makes the operation of the plasma device must increase energy and consume a huge amount of gas
Another disadvantage of using jet plasma equipment is that the plasma takes place at a distance higher than 1 mm above the surface being treated, which when combined with the high flow of working gas can lead to Before, the active ion part of the plasma has been recombined, so the energy efficiency of such a device is extremely low
Furthermore, the US application patent "20050045103" further shows that the discharge plasma generated by these devices is in direct contact with the surface of the metal electrode, thus causing the electrode surface to be eroded
This makes it even more detrimental to use such devices in the consumer market, as such plasmas don't last very long, and due to the high power used, such devices are generally not safe for humans

Abstract

The invention provides a portable atmospheric plasma cleaner which is a hand-held device used for cleaning glass and glass coating materials, and mainly comprises an electrode system and an water vapor supplying module; the electrode system adopts a common household power to produce a plasma layer; the water vapor supplying module integrates a water tank with an airflow channel into a whole and adopts a small water atomizer to mix the water and the air, thereby the mixed air is boosted and the surface of a plasma action area is introduced, at the same time, the mixed air flows through the back surface of a plasma bottom plate before the plasma action area is introduced, so as to maintain the temperature of the plasma bottom plate to be under the room temperature. The injection of a small quantity of the water vapor into the plasma action area can reduce the ozone discharged when the plasma is produced, thereby achieving the efficacy of environmental protection. The plasma cleaner is also applicable to the glass, the surface of which is coated with materials containing metal oxides or an organic material layer, the material which is coated with a SiO2 layer as well as the material, the SiO2 layer of which is coated with the organic material layer.

Description

technical field [0001] The invention relates to a cleaning device for the surface of coated glass materials, especially a portable atmospheric plasma cleaning machine, which can achieve safe and convenient cleaning functions through the reaction of active plasma substances and pollutants on the surface. Background technique [0002] Since the nineteenth century AD, glass or glass coating materials have been widely used in human society. In the beginning, glass was only used in buildings as windows. Recently, modern buildings or skyscrapers have widely used glass to replace the old traditional bricks or concrete to replace the walls. Glass also plays a pivotal role in interior decoration, replacing traditional walls. For example, this design can be seen in many bathrooms and greenhouses in many houses. The application of other related glass materials is more diverse in daily life, such as mirrors, tables, chairs, basins, etc., and everything you can imagine will use it. In ...
