[0023] In addition, the technical features involved in the different embodiments of the utility model described later can be combined with each other as long as they do not conflict with each other.

[0024] See also Figures 1-2 In the embodiment of the utility model, a high-efficiency electric flame stove burner includes a burner top plate 1, a gas collecting box 2, a plurality of fire outlet pipes 3 arranged on the burner top plate 1, a plurality of ceramic tubes 4 corresponding to the fire outlet pipes 3 and arranged on the bottom plate of the gas collecting box 2, and an anode needle 5 arranged on the bottom wall of the ceramic tube 4; an arc-striking end 51 is arranged on the upper end of the anode needle 5, and the arc-striking end 51 is conical and extends upward to the inner cavity of the ceramic tube 4; the fire outlet pipe 3 serves as the cathode of the utility model. When the anode needle 5 is connected to a high-voltage power supply, an arc effect occurs between the arc-striking end 51 and the fire outlet pipe 3, and the gas is ionized to form a high-energy plasma.

[0025] Among them, the circumferential wall of the ceramic tube 4 is provided with a plurality of guide holes 41 which form an inclined angle with the circumferential wall; the gas collecting box 2 is fixedly connected to the upper furnace head top plate 1 by screws, the inner cavity of the gas collecting box 2 forms a closed space, and the guide holes 41 connect the inner cavity of the gas collecting box 2 with the inner cavity of the ceramic tube 4; the bottom plate of the gas collecting box 2 is provided with an intake fan 21 which provides gas to the inner cavity of the gas collecting box 2; the intake fan 21 inhales external air, and the gas is introduced into the inner cavity of the ceramic tube 4 through the inclined guide holes 41 to form a vortex airflow; the vortex airflow cools the ceramic tube 4 and the firing tube 3, so that the service life of the ceramic tube 4 and the firing tube 3 is longer, and at the same time, the aerodynamic force generated by the vortex airflow pushes the plasma upward to form a plasma fluid.

[0026] In the embodiment of the utility model, the radial cross-sectional area of ​​the firing tube 3 is smaller than the radial cross-sectional area of ​​the ceramic tube 4; due to the contraction effect of the firing tube 3, the flow velocity of the plasma fluid after entering the firing tube 3 is significantly accelerated, forming a fast plasma jet that effectively sprays out of the firing tube 3 and heats the pot body.

[0027] The fire outlet pipe 3 is cylindrical and has a ring-shaped groove 31 at the lower end; the upper end of the fire outlet pipe 3 extends upward through the burner top plate 1, and the groove 31 limits the upward movement of the fire outlet pipe 3; the top end of the ceramic tube 4 is embedded in the groove 31, and the bottom wall of the ceramic tube 4 is closed; since the fire outlet pipe 3 is a contracted cylindrical shape, its upper and lower radial diameters are smaller than those of the flamethrowers in the prior art. Therefore, the fire outlet pipe 3 of the utility model uses relatively less metal material in the manufacturing process, and the weight of the fire outlet pipe 3 is also lighter than that of the flamethrowers in the prior art, thereby reducing the quality of the burner and the production cost.

[0028] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
