Description

Technical Field

[0001] The utility model relates to an electric flame stove, in particular to an insulating component of an electrode. Background Technique

[0002] An electric flame stove is a cooking stove that can directly convert electric energy into high-temperature and high-spectral arc for heating cookware without any fuel.

[0003] For example, the patent with the authorization announcement number CN221005149U proposes a burner head, including: a furnace chamber, several ceramic tubes, an electrode needle arranged in the middle of the ceramic tubes, and several spray tubes for generating circuit reflux with the electrode needle; a hollow installation groove is arranged at the lower end of the ceramic tube, and the electrode needle passes through the installation groove and is electrically connected to an external power supply of the burner head. The electrode needle of the above patent is fixed to the installation groove at the lower end of the ceramic tube by threads, but during later transportation or user use, the electrode needle is prone to looseness, affecting normal use.

[0004] The R & D personnel made technical improvements. Another example is the patent with the application number CN202410091845.X, which proposes a commercially used stove burner head with optimized structure, including: a burner head top plate, a gas collecting box, and multiple plasma generators; the plasma generator includes a contraction tube as the cathode, an anode cylinder, and an insulating ceramic tube; the ceramic tube is a cylindrical shape with both ends open and communicating, a circular first embedding groove is arranged at the lower end of the contraction tube, and the upper end of the ceramic tube is embedded in the first embedding groove; the radial diameter of the contraction tube is smaller than the radial diameter of the ceramic tube; a circular second embedding groove is arranged at the lower end of the ceramic tube, and the anode cylinder is embedded in the second embedding groove. The assembly of the above patent's commercially used stove burner head is simple, and the gas collecting box in contact with the anode cylinder is made of insulating mica plate. However, during the experiment and application process, the electromagnetic waves generated by the discharge penetrate the mica plate, affecting the electronic components of the circuit board below, resulting in overheating and damage of the electronic components; in addition, the mica plate is also relatively easy to be damaged during the installation process.

[0005] Therefore, the above two sets of prior art solutions have not achieved ideal effects. Under the condition that the burner head housing is made of stainless steel, the utility model makes improvements to the ceramic tube of the insulating component. Content of the Utility Model

[0006] The utility model aims to provide a technical solution that can solve the above problems to overcome the above deficiencies.

[0007] A ceramic component for installing the electrode pin of an electric flame stove, comprising an upper ceramic tube and a lower ceramic tube, wherein the upper ceramic tube and the lower ceramic tube are of a hollow structure; a first convex ring is provided at the bottom end of the upper ceramic tube, and the space between the top end of the first convex ring and the bottom end of the upper ceramic tube is closed. An annular limiting ring is provided at the upper end inside the first convex ring; a second convex ring is provided at the top end of the lower ceramic tube, and the space between the bottom end of the second convex ring and the top end of the lower ceramic tube is closed; the inner diameter of the second convex ring is slightly larger than the outer diameter of the first convex ring, so that the first convex ring can be sleeved into the second convex ring.

[0008] Preferably, the inner diameter of the lower ceramic tube is smaller than the inner diameter of the first convex ring.

[0009] Preferably, the inner empty groove of the lower ceramic tube is an insulating channel for the electrode electrical connection circuit.

[0010] Preferably, the wall thickness of the lower ceramic tube is at least 2 mm.

[0011] Preferably, at least one air inlet groove is provided on the wall of the upper ceramic tube.

[0012] The advantages of the present utility model are as follows: Under the condition that the furnace head housing is made of stainless steel, the upper ceramic tube and the lower ceramic tube are combined, and the electrode pin is clamped and fixed inside the ceramic component. The fixed connection method makes the electrode pin stable, and the installation method is simple. Compared with the threaded connection in the prior art, the ceramic component of the present utility model makes the electrode pin stable; compared with the electric welding connection in the prior art, the installation process of the ceramic component and the electrode pin of the present utility model is simple, reducing the labor cost in assembly and disassembly.

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.

[0020] In addition, the technical features involved in different embodiments of the present utility model described subsequently can be combined with each other as long as they do not conflict with each other.

[0021] Please refer to Figure 1 , in the embodiments of the present utility model, a ceramic component for installing the electrode needle of an electric flame stove includes an upper ceramic tube 1 and a lower ceramic tube 2, and the upper ceramic tube 1 and the lower ceramic tube 2 are of a hollow structure;

[0022] A first convex ring 11 is provided at the bottom end of the upper ceramic tube 1, and the space between the top end of the first convex ring 11 and the bottom end of the upper ceramic tube 1 is closed. A second convex ring 21 is provided at the top end of the lower ceramic tube 2, and the space between the bottom end of the second convex ring 21 and the top end of the lower ceramic tube 2 is closed. The inner cavity of the lower ceramic tube 2 is an insulating channel for the electrode electrical connection circuit; the wall thickness of the lower ceramic tube 2 is at least 2 mm; this enables the ceramic component to have better insulation and avoids the occurrence of arcing between the electrode needle installed in the ceramic component and the conductor stove head housing.

[0023] In this embodiment, the inner diameter of the second convex ring 21 is slightly larger than the outer diameter of the first convex ring 11, so that the first convex ring 11 can be sleeved into the second convex ring 21.

[0024] In this embodiment, an annular limiting ring 12 is provided at the upper end inside the first convex ring 11, and the inner diameter of the lower ceramic tube 2 is smaller than the inner diameter of the first convex ring 11. As Figure 2 shown, a limiting platform 100 is usually provided at the bottom or middle of the electrode needle. The outer diameter of the limiting platform 100 is slightly smaller than the inner diameter of the first convex ring 11. After the electrode needle passes through the limiting ring 12, the limiting platform 100 can be embedded into the first convex ring 11, and the limiting ring 12 restricts the excessive upward movement of the limiting platform 100. The top surface of the lower ceramic tube 2 is clamped with the bottom surface of the limiting platform 100 of the electrode needle, so that the limiting platform 100 is fixed in the first convex ring 11. Therefore, in this new type of implementation, the installation of the electrode needle is extremely simple, the production efficiency is improved, and the ceramic component is fixed under the clamping of the furnace head housing. Compared with the prior art, the installation of the electrode needle in this clamping and fixing method is more firm.

[0025] In this embodiment, as Figure 2 the limiting platform 100 of the electrode needle can be circular, but it can also be of other shapes.

[0026] At least one air inlet groove 13 is provided on the wall of the upper ceramic tube 1 for introducing gas.

[0027] For those skilled in the art, it is obvious that the present invention 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 invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention 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 invention.
