Hand-held low-temperature plasma jet flow device

Abstract

The invention discloses a hand-held plasma jet flow device. The jet flow device comprises an insulating shell, the insulating shell is internally provided with a jet flow unit, a dielectric barrier discharging unit and a charging module for providing power for the jet flow unit and the dielectric barrier discharging unit, the charging module comprises a detachable lithium battery and a charging interface, the jet flow unit introduces airflow into the insulating shell, a discharging region of the dielectric barrier discharging unit generates plasma, and the jet flow unit not only continuously transports the airflow to the discharging area, but also can cool the plasma generated by the discharging area. According to the jet flow device, the detachable lithium battery is arranged in the jet flow device and provides current for the jet flow unit and the dielectric barrier discharging unit, and without an external power supply, the device is convenient to carry and use and can serve as small portable emergency equipment for home or outdoor activities.

Description

technical field [0001] The invention relates to the technical field of plasma generation devices, in particular to a hand-held low-temperature plasma jet device. Background technique [0002] In recent years, the research on low-temperature plasma and its application technology has attracted the attention of academia and industry. The interaction between low-temperature plasma and cells shows various biological effects, so it is applied in many fields, including the disinfection and sterilization of medical equipment. Bacteria, clinical treatment, etc. However, the traditional low-temperature plasma needs to be generated by gas discharge in a low-pressure environment, which requires high environmental requirements and high application costs, making it difficult to promote and use it on a large scale. [0003] Although low-temperature plasma generating devices under atmospheric pressure have also appeared in the prior art, there are still many defects: the existing low-tempe...

Problems solved by technology

However, the traditional low-temperature plasma needs to be generated by gas discharge in a low-pressure environment, and the environmental requirements and application costs are high, making it difficult to promote and use it on a large scale.

[0003] Although low-temperature plasma generating devices under atmospheric pressure have also appeared in the prior art, there are still many defects: the existing low-temperature plasma generating devices under atmospheric pressure are bulky, inconvenient to carry, and require external Supply rare gases such as argon and helium, such as a handheld plasma generating device and method disclosed in patent CN105430859A. One technical problem is that it is difficult to carry with you and requires an external power supply, such as a hand-held large-area low-temperature plasma generator disclosed in patent CN103945627A

Due to the limitations of the above defects, the low-temperature plasma generation device cannot be applied to outdoor environments such as outdoor activities and natural disaster emergencies.
