The large voltage difference causes the air between the positive electrode 5 and the corresponding negative electrode 6 to be broken down and maintain conductivity, which is an arc phenomenon. Plasma is generated in the arc environment, and the temperature of the plasma is as high as 1000 degrees or more.

[0024] The upper burner is installed on the top of the body 1, the upper burner plate 2 is made of a conductive material, and the upper burner plate 2 is electrically connected to the negative terminal of the power supply; the negative electrode 6 is arranged on the upper burner plate 2 and extends upward, and the negative electrode 6 is a hollow cylindrical shape; the lower burner plate 3 is made of an insulating material, such as ceramic, mica and other high temperature resistant insulating materials, and the upper burner plate 2 and the lower burner plate 3 are connected by screws;

[0025] The ceramic tube 4 is installed between the upper furnace head plate 2 and the lower furnace head plate 3. The upper end of the ceramic tube 4 is connected to the lower end of the negative electrode 6, and the positive electrode 5 is installed in the inner cavity of the ceramic tube 4; and the lower end of the ceramic tube 4 is connected to the bottom wall of the lower furnace head plate 3. In this embodiment, the lower furnace head plate 3 is made of insulating material, and the ceramic tube 4 is set to be open at both ends. Compared with the prior art, the utility model saves the manufacturing materials of the ceramic tube 4 and avoids the risk of arcing between the positive electrode 5 and the lower furnace head plate 3.

[0026] The circuit board 7 is installed in the body 1, and a plurality of guide posts 71 are provided on the circuit board 7; the lower furnace head plate 3 is provided with a plurality of mounting holes 31 corresponding to the positive electrode 5, and one end of the guide post 71 passes through the mounting hole 31 and is electrically connected to the corresponding positive electrode 5, and the connection method is relatively simple. In this embodiment, the guide post 71 is selected to be elastically liftable, and one end of the guide post 71 only needs to contact the positive electrode 5, and no welding or screw connection is required.

[0027] The circumferential wall of the ceramic tube 4 is also provided with a plurality of air guide holes 41; the lower furnace head plate 3 is provided with an air intake fan 32, and the air intake fan 32 provides gas for the cavity between the upper furnace head plate 2 and the lower furnace head plate 3; with the circumference of the negative electrode 6 as a reference, the air guide holes 41 are inclined, and the gas enters the inner cavity of the ceramic tube 4 through the air guide holes 41 to form a vortex motion; in this embodiment, the rotating gas cools the ceramic tube 4 and mixes with the plasma to form a plasma fluid that rotates upward.

[0028] The circumferential diameter of the cross section of the negative electrode 6 is smaller than the circumferential diameter of the cross section of the ceramic tube 4 . When the plasma fluid enters the inner cavity of the negative electrode 6 , the negative electrode 6 contracts, causing the plasma flow rate to become faster, and eventually forming a fast plasma jet that is ejected out of the outside of the negative electrode 6 .
