[0053] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0054] Specific implementation example description section.

[0055] Embodiment 1:

[0056] Reference Figures 1 to 3 The burner head of the electric flame stove of this embodiment includes a burner head plate 1, a burner head shell 2, a plurality of anode electrode head assemblies 10 and a circuit board 4.

[0057] The furnace head housing 2 is provided with a bottom plate 21 and a side plate 23 fixed on the bottom plate 21. A positioning column 22 with a through hole is provided on the bottom plate 21 in the direction facing the furnace head plate 1 and corresponding to the anode electrode head assembly 10.

[0058] The furnace head plate 1 is fixed on the top of the side plate 23, and forms a heat-insulating cavity with the bottom plate 21 and the side plate 23. A plurality of cathode tubes 16 are arranged on the furnace head plate 1, and the cathode tubes 16 are formed by a plurality of circular bosses with through holes processed on the surface of the furnace head plate 1 by sheet metal stretching and punching technology.

[0059] The cathode tube and the furnace head plate are integrally formed, which means that there is no need to manufacture the cathode tube separately or to install the cathode tube, thus simplifying the production process and reducing the production cost.

[0060] See also Figure 3 In actual application, the top tube opening of the cathode tube 16 converges inward to form an annular shielding ring, which can not only effectively prevent water overflowing from the pot during cooking from entering the stove head through the cathode tube, but also shield the anode electrode head assembly to a certain extent, thereby increasing the safety of the electric flame stove.

[0061] See also Figure 4 In practical applications, the top tube mouth of the cathode tube 16 can also converge inward and bend downward to extend into the inner cavity of the cathode tube 16 to form an inward curling edge 161. The end of the curling edge 161 can react with the electrode head 13 to generate an arc. At the same time, the highest waist position of the electrode connector 14 and the inner wall of the cathode tube 16 can also discharge to generate an arc. By adjusting the size of the stove head current, it is possible to achieve arc reactions between the electrode head 13 and the end of the curling edge 161 and between the electrode connector 14 and the inner wall of the cathode tube 16 at the same time or separately, so that the firepower (temperature) adjustment range of the electric flame stove is larger. At the same time, the inwardly converging tube mouth can not only effectively prevent water overflowing from the pot during cooking from entering the stove head from the cathode tube, but also shield the anode electrode head assembly to a certain extent, thereby increasing the safety of the electric flame stove.

[0062] The circuit board 4 is fixed below the bottom plate 21, and a patch nut 5 is provided thereon corresponding to the anode electrode head assembly 10. The bottom end of the electrode rod 12 of the anode electrode head assembly 10 passes through the positioning column 22 to cooperate with the patch nut 5 and is electrically connected to the circuit board 4, so as to be vertically fixed in the heat insulation cavity.

[0063] The electrode rod 12 and the circuit board 4 are connected by threads, which is convenient for installation and disassembly.

[0064] A fan 3 is also provided on the side plate 23 of the burner housing 2, the air outlet of the fan 3 is connected to the heat insulation cavity, and the air inlet of the fan 3 faces the outside of the burner housing 2. A water guide groove 6 is also provided on the bottom plate 21, and the water guide groove 6 is located outside the heat insulation cavity and below the fan 3.

[0065] The water guide groove 6 is arranged below the fan 3 . When water enters the heat-insulating cavity through the cathode tube 16 and the ceramic tube 15 , it can flow into the water guide groove 6 through the gap between the fan 3 and the furnace head shell 2 , and then flow out through the water guide groove 6 .

[0066] For some possible solutions, see Figure 3 , Figures 5 to 7 The anode electrode head assembly 10 includes an electrode rod 12 , an electrode head 13 , an electrode joint 14 and a ceramic tube 15 .

[0067] Both ends of the electrode rod 12 are provided with threaded columns, the threaded column at the top end cooperates with the electrode connector 14 , and the threaded column at the bottom end cooperates with the patch nut 5 of the circuit board 4 .

[0068] The electrode head 13 is mushroom-shaped, with an umbrella-shaped tip at one end and a cylindrical fixing post at the other end; the electrode connector 14 is a rotating body with small ends and a large middle, one end of the rotating body is provided with a circular hole for fixing the fixing post of the electrode head 13, and the other end is provided with an internal threaded hole. The fixing post of the electrode head 13 is fixed in the circular hole of the electrode connector 14 by riveting, and the internal threaded hole of the electrode connector 14 cooperates with the threaded post at the top of the electrode plate 12 to fix the electrode head 14 to the top of the electrode rod 12. The electrode head 13 and the electrode connector 14 are located at the lower position in the corresponding cathode tube 16, leaving a gap between them and the inner wall of the cathode tube 16, and are coaxial with the cathode tube 16.

[0069] In this embodiment, the electrode head 13 is made of tungsten alloy material, and the furnace head plate 1, the electrode rod 12 and the electrode joint 14 are all made of stainless steel material. In practical applications, the furnace head plate 1, the electrode head 13 and the electrode joint 14 can all be made of conductive and high temperature resistant conductive materials, such as copper, stainless steel, tungsten alloy, graphite, etc., as long as the melting point of the material of the electrode head 13 is higher than the melting point of the material of the furnace head plate 1 and the electrode joint 14, for example, stainless steel or copper is used as the material for making the furnace head plate 1 and the electrode joint 14, and tungsten alloy or graphite is used as the material of the electrode head 13.

[0070] According to the tip discharge principle, the top of the anode electrode head is pointed, and long-term high-temperature discharge can easily melt the tip. In this embodiment, the electrode head 13 and the electrode connector 14 are used to form the anode electrode. A conductive material with a high melting point is used as the electrode head, and a conductive material with a low melting point is used as the electrode connector to achieve the connection between the electrode head and the electrode rod. Compared with the prior art in which the anode electrode head is integrally formed of stainless steel, this not only overcomes the problem that metals with high melting points are difficult to process, but also reduces production costs and extends the service life of the anode electrode head.

[0071] The ceramic tube 15 is provided with an inner ring 151 and an outer ring 152. The inner ring 151 and the outer ring 152 are connected by a plurality of blades 153, wherein the top surface height of the inner ring 151 is lower than the top surface height of the outer ring 152, and the blades 153 are arranged obliquely around the inner ring 151. The inner ring 151 is fixed on the electrode rod 12 and is coaxial therewith, and the top of the inner ring 151 abuts against the bottom of the electrode connector 14; the top of the outer ring 152 abuts against the bottom of the inner wall of the cathode tube 16.

[0072] The blades of the ceramic tube are arranged obliquely, and can be formed at one time when the ceramic mold is used to process the ceramic embryo. Compared with the prior art, there is no need to process the air guide holes again, which simplifies the production process and saves production costs.

[0073] After the stove is powered on, the highest waist position of the anode electrode and the inner side of the cathode tube 16 discharge to generate an arc. After the fan 3 starts to blow wind into the heat-insulating cavity, the arc is blown out of the cathode tube 16 through the inclined blades 153. Since the blades turn the wind into a whirlwind, the arc eventually rotates under the action of the whirlwind. The advantages of this are: 1. The wind can cool down the positive and negative electrodes; 2. The wind blows the arc and the temperature generated by the two electrodes to the heated bottom of the pot, which is conducive to heat conversion; 3. The whirlwind prevents the cathode tube 16 from generating temperature at one point, extending the service life of the cathode tube 16.

[0074] For some possible solutions, see Figures 8 to 11 The electrode head 13 is an annular disc; a fixing column is provided on the top of the electrode connector 14, and an internal threaded hole is provided on the bottom; the electrode head 13 is sleeved and fixed on the fixing column, and a gap is left between the outer edge of the electrode head 13 and the inner wall of the cathode tube 16. In practical applications, the gap can be set to 3 to 5 mm.

[0075] The electrode head adopts an annular disc to realize annular discharge, increase the discharge area, generate more arc, greater firepower, and improve the heating effect.

[0076] In practical applications, the anode electrode head assembly 10 may further include an insulating ceramic 17. The insulating ceramic 17 is fixed to the fixing column of the electrode connector 14, and its bottom abuts against the electrode head 13 to fix the electrode head 13 on the electrode connector 14. An insulating ceramic cover is provided above the electrode head 13 to effectively prevent electric shock accidents.

[0077] In practical applications, the insulating ceramic 17 may be a rotating body with small ends and a large middle, or may be set to other shapes.

[0078] The burner head of the electric flame stove and the anode electrode head assembly thereof of the utility model have the following advantages:

[0079] 1. The cathode tube and the furnace head plate of the furnace head are integrally formed, and there is no need to make the cathode tube separately, which simplifies the production process and reduces the cost. The conductive material with a high melting point is used as the electrode head, and the conductive material with a low melting point is used as the electrode joint to realize the connection between the electrode head and the electrode rod, which not only overcomes the problem that the conductive material with a high melting point is difficult to process, but also reduces the production cost;

[0080] 2. The electrode head is made of tungsten alloy and fixed on stainless steel by riveting machine technology, which not only takes advantage of the high temperature resistance of tungsten alloy but also avoids the difficult processing characteristics of tungsten alloy;

[0081] 3. An insulating ceramic cover is installed above the electrode head to effectively prevent electric shock accidents;

[0082] 4. The ceramic tube uses multiple inclined blades to produce cyclone characteristics. When the ceramic mold is used to process the ceramic embryo, it can be formed at one time, and there is no need to process the air guide hole again, which simplifies the production process and saves production costs;

[0083] 5. The electrode rod and the circuit board are connected by threads, which is convenient for installation and disassembly;

[0084] 6. A water tank is provided to facilitate the discharge of water entering the heat insulation cavity to the outside of the stove head.
