Description

Technical Field

[0001] The utility model specifically relates to an electrode assembly of an electric flame stove. Background Art

[0002] In the field of modern commercial stoves, high-power and high-energy commercial stoves are usually used. The most common one is the commercial gas stove. By using "high firepower", the commercial gas stove meets the needs of fast stir-frying in restaurants, hotels, banquets and feasts. At the same time, the dishes stir-fried with "high firepower" have a good taste. However, due to frequent gas leakage and explosion accidents of gas stoves, high-power commercial induction cookers were born. The commercial induction cookers use high-power current to heat the frying pan, replacing part of the gas stoves. However, in actual use, the heat of the induction cooker is not as high as that of the gas stove with open fire, and the taste of the dishes is not as good as that of stir-frying with "open fire".

[0003] In view of the deficiencies of the above two types of stoves, researchers have developed an electric flame stove that can directly convert electrical energy into high-temperature and high-spectral electric arcs (electric flames) for heating without any fuel.

[0004] For example, the patent with the authorization announcement number CN221005149U proposes a burner head of a commercial electric flame stove, including: a furnace chamber, several ceramic tubes, electrode pins arranged in the middle of the ceramic tubes, and several spray pipes for circuit reflux with the electrode pins; a hollow installation groove is arranged at the lower end of the ceramic tube, and the electrode pin passes through the installation groove and is electrically connected to the external power supply of the burner head.

[0005] The electrode pin of the above patent is fixed to the installation groove at the lower end of the ceramic tube by threads. However, during later transportation or user use, the electrode pin is prone to looseness, affecting the normal use of the commercial electric flame stove. Summary of the Utility Model

[0006] The utility model aims to provide a technical solution to solve the above problems in order to overcome the above situations.

[0007] An electrode pin for an electric flame stove includes an ion head at its upper end and a connecting column at its lower end; a limiting clamping platform is arranged at the connection between the ion head and the connecting column, the top of the ion head is conical, and the connecting column can be electrically connected to a power supply;

[0008] Preferably, the surface of the connecting column is smooth for inserting into the ceramic tube;

[0009] Preferably, the limiting clamping platform is annular, and its outer diameter is greater than the outer diameter of the ion head or the outer diameter of the connecting column, and the limiting clamping platform is used for fixing in the ceramic tube structure;

[0010] Preferably, the ion head, the limiting clamping platform and the connecting column are integrally made of 304 stainless steel;

[0011] An electrode assembly includes the electrode needle described in any one of the above, and further includes an upper ceramic tube and a lower ceramic tube adapted to the electrode needle. Both the upper ceramic tube and the lower ceramic tube are of a hollow structure;

[0012] Preferably, the limiting clamping platform is installed between the upper ceramic tube and the lower ceramic tube, so that the electrode needle is fixed inside the upper ceramic tube and the lower ceramic tube;

[0013] Preferably, a clamping ring with an inner diameter smaller than the outer diameter of the limiting clamping platform is arranged in the middle of the upper ceramic tube.

It can be a wireless connection or a wired connection. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0022] 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.

[0023] Please refer to Figure 1 , in an embodiment of the present utility model, an electrode needle includes an ion head 11 at its upper end and a connecting column 13 at its lower end; a limiting clamping platform 12 is provided at the connection between the ion head 11 and the connecting column 13. The top of the ion head 11 is conical, and the connecting column 13 can be electrically connected to a power source;

[0024] The surface of the connecting column 13 is smooth and is used for being inserted into a ceramic tube.

[0025] The limiting clamping platform 12 is annular, and its outer diameter is larger than the outer diameter of the ion head 11 or the outer diameter of the connecting column 13. The limiting clamping platform 12 is used for being fixed inside a ceramic tube structure;

[0026] The ion head 11, the limiting clamping platform 12, and the connecting column 13 are integrally made of 304 stainless steel;

[0027] Please refer to Figure 1-2 , an electrode assembly includes the electrode needle of any one of the above, and further includes an upper ceramic tube 21 and a lower ceramic tube 22 adapted to the electrode needle. The limiting clamping platform 12 is installed between the upper ceramic tube 21 and the lower ceramic tube 22, so that the electrode needle is fixed inside the upper ceramic tube 21 and the lower ceramic tube 22.

[0028] A clamping ring 211 with an inner diameter smaller than the outer diameter of the limiting clamping platform 12 is provided in the middle of the upper ceramic tube 21.

[0029] Since the inner diameters of the upper ceramic tube 21 and the lower ceramic tube 22 are designed to allow the ion head 11 to pass through the upper ceramic tube 21 and the connecting column 13 to be inserted into the lower ceramic tube 22, and the outer diameter of the limit clamping platform 12 is larger than the inner diameters of the snap ring 211 and the lower ceramic tube 22, the snap ring 211 provided at the lower end inside the upper ceramic tube 21 restricts the excessive upward movement of the limit clamping platform 12 of the electrode needle. At the same time, the top surface of the wall of the lower ceramic tube 22 restricts the downward movement of the limit clamping platform 12 of the electrode needle. By being clamped between the upper ceramic tube 21 and the lower ceramic tube 22 through the limit clamping platform 12, the electrode needle is fixed inside the ceramic tube assembly. In summary, compared with the threaded connection in the prior art, the installation of the present utility model is relatively simple, which improves production efficiency and reduces labor costs, and has a firm structure and is not easy to loosen.

[0030] 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, it is intended to embrace all changes falling within the meaning and scope of the equivalent elements of the claims in the present utility model.
