[0019] In addition, the technical features involved in different embodiments of the present utility model described hereinafter can be combined with each other as long as they do not conflict with each other.

[0020] Please refer to Figure 1 , in an embodiment of the present utility model, an electric flame stove burner head convenient for maintenance includes a burner head top plate 1, a burner head bottom shell 2, and a plurality of electrode assemblies 3. The burner head top plate 1 and the burner head bottom shell 2 enclose to form a burner head cavity.

[0021] In this embodiment, as Figure 2 shown, a plurality of mounting holes 11 corresponding to the electrode assemblies 3 are provided on the burner head top plate 1, and threads are preset along the edges of the mounting holes 11 on the burner head top plate 1. As Figure 3 shown, the electrode assembly 3 includes a flame spraying tube 31, an electrode pin 32, and a ceramic tube 33, and threads are preset at the lower end of the flame spraying tube 31.

[0022] The lower end of the flame spraying tube 31 is fixedly connected to the corresponding mounting hole 11 by threads. Usually, during the transportation of the electric flame stove or the user's use process, the electrode pin 32 fixed by threads is likely to become loose, affecting the normal working state of the electric flame stove. In the present utility model, the flame spraying tube 31 is fixed on the burner head top plate 1 by threads. If the electrode pin 32 becomes loose, the user can unscrew the flame spraying tube 31, further tighten the loose electrode pin 32, and then restore the flame spraying tube 31 to its original position. Compared with the prior art, when facing the problem of the electrode pin 32 becoming loose, the present utility model is simple and convenient to repair, reducing the cumbersome steps of disassembling and installing the burner head.

[0023] In the next embodiment, a connecting tube 331 is provided at the lower end of the ceramic tube 33. The interior of the ceramic tube 33 is in communication with the interior of the connecting tube 331. The electrode pin 32 passes through the bottom of the ceramic tube 33 and is fixed in the connecting tube 331 by threads. The other end of the electrode pin 32 extends upward and there is a distance of 3 mm - 5 mm between the electrode pin 32 and the flame spraying tube 31. The flame spraying tube 31 is a conductor for circuit return and is connected to the ground wire. When the electrode pin 32 is energized with high voltage, the voltage difference causes the current to break down the air to maintain conductivity, and the surrounding air is continuously ionized to form a high-temperature plasma for heating the cookware.

[0024] In the next embodiment, the connecting pipe 331 passes downward through a through hole preset on the bottom shell 2 of the burner head. The outer diameter of the main body of the ceramic pipe 33 is larger than the inner diameter of the through hole of the bottom shell 2 of the burner head, and the bottom shell 2 of the burner head limits the excessive downward movement of the bottom of the ceramic pipe 33, so that the bottom of the ceramic pipe 33 abuts against the bottom shell 2 of the burner head.

[0025] The top surface of the circumferential wall of the ceramic pipe 33 abuts against the bottom surface of the circumferential wall of the flame spraying pipe 31. The top plate 1 and the bottom shell 2 of the burner head are fixed by bolts, so that the ceramic pipe 33 is firmly fixed between the flame spraying pipe 31 and the bottom shell 2 of the burner head. The installation is simple, reducing the cumbersome installation process of the prior art and improving the production and manufacturing efficiency.

[0026] The inner cavities of the ceramic pipe 33 and the flame spraying pipe 31 form a flame spraying channel. At least one air inlet hole 332 is further provided on the circumferential wall of the ceramic pipe 33, and the air inlet hole 332 communicates the flame spraying channel and the burner head cavity. Usually, air is provided to the burner head cavity through a burner head fan. The gas is introduced into the flame spraying channel through the air inlet hole 332, and an air flow is generated. The power of the air flow enables the plasma to form a fast jet and spray out of the flame spraying pipe 31 to heat the cookware above.

[0027] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model.
