Destroy the big swirling eddy in main aperture 132.In this way, in being limited in because of the plasma-based 152 caused by big flow rotation
The phenomenon that heart district domain, can be because there is shunting to screw in groove 134 and be destroyed, therefore nozzle 130 can expand the eruption model of plasma-based 152
It encloses, so that plasma-based torch 100 can carry out the plasma-based processing of large area.
The aperture of nozzle 130 and groove can be there are many patterns.A and Fig. 2 B referring to figure 2., is painted respectively according to this reality
With the upper schematic diagram and partial enlargement upper schematic diagram of a kind of nozzle of plasma-based torch of a novel embodiment.It is real herein
It applies in mode, the shape of the main aperture 132a of nozzle 130a is circle, and the shape of each groove 134a is arc-shaped.Some
In example, these grooves 134a is arranged in the outer rim 136a of groove 134a based on the central loop of circular main aperture 132a,
And main aperture 132a and these grooves 134a is made to constitute the aperture of class plum blossom-shaped.These grooves 134a can equally spacedly be arranged in master
Want the outer rim 136a of aperture 132a.
As shown in Fig. 2A and Fig. 2 B, the big air-flow 154a in main aperture 132a, which has, shunts the groove that 156a screws in its periphery
In 134a, and the big air-flow 154a in main aperture 132a can be destroyed.Whereby, the setting of groove 134a can destroy big air-flow 154a
The phenomenon that plasma-based caused by rotation is limited in central area.Therefore, nozzle 130a can expand the eruption range of plasma-based, in turn
Make plasma-based torch that can carry out the plasma-based processing of large area.
A and Fig. 3 B referring to figure 3., is a kind of plasma-based torch for being painted the embodiment according to the utility model respectively
