Embodiment Construction
[0043] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0044] like Figure 4 , Figure 5 As shown, the safety grounding device of the plasma jet includes a first insulating sleeve 1 and a second insulating sleeve 2; the first insulating sleeve forms a tight package on the quartz glass tube, and the inner surface of the first insulating sleeve corresponds to Each annular electrode on the outer wall of the quartz glass tube 102 is a concave structure, forming an air gap 1a left by the annular electrode, and the concave structure also has a radially penetrating channel 1b for wiring; the second insulation The bushing is sleeved and fixed on the outside of the first insulating bushing, and there is a gap between the bushing and the first insulating bushing.
[0045] The quartz glass tube adjacent to the upper end and the lower end of the ring electrode is tightly wrapped by the first insula...

The invention discloses a plasma jet safety grounding device, so as to ensure the safety of a low-temperature plasma jet device. The plasma jet safety grounding device comprises a first insulating sleeve and a second insulating sleeve, wherein the first insulating sleeve forms tight coating on a quartz glass tube; the inner side surface, corresponding to each annular electrode on the outer wall ofthe quartz glass tube, of the first insulating sleeve has a concave structure, an air gap is left for the annular electrode, the concave structure also has a radially penetrating passage, and the wire of the annular electrode is led out through the air gap and the radially penetrating passage; the second insulating sleeve sleeves and is fixed outside the first insulating sleeve, and an air gap iskept with the first insulating sleeve. The exposed annular electrode is coated through an air layer and an insulating medium layer and is reliably insulated, and due to a built-in electrically-connected wiring channel, the safety of the low-temperature plasma jet device is improved, and discharge to a handheld human or biological tissue by a high voltage electrode is prevented.
Description
technical field [0001] The invention belongs to the technical field of electrical engineering grounding protection, and relates to a device for safely grounding during jet discharge. Background technique [0002] Atmospheric pressure-cooled plasma is an emerging research field in recent years. Atmospheric pressure-cooled plasma can be produced under atmospheric pressure, the particle temperature is close to room temperature, contains a large number of active particles, the particles are small, and the energy concentration is concentrated in many fields such as the environment. Protection, biomedicine, nano-manufacturing, chip etching and other fields have broad application prospects. Among them, specific examples of the application of low-temperature plasma in the field of biomedicine include the treatment of tumors, the treatment of skin diseases, and the killing of bacteria that cause sepsis. [0003] Laboratories generally use dielectric barrier discharge, creeping disch...
