[0013] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following briefly introduces the drawings required for use in the embodiments or the description of the prior art. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative labor.

[0016] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0018] Furthermore, in the description of this utility model, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; internal connections between two components; wireless connections or wired connections. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

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

[0020] See also Figure 2 In an embodiment of the present invention, a transformer for an electric flame stove includes a PCB board 1, a magnetic core assembly 2, a primary winding 3, and a secondary winding 4;

[0021] The magnetic core assembly 2 includes a first magnetic core 21 and a second magnetic core 22. The first magnetic column 23 and the second magnetic column 24 on the first magnetic core 21 are respectively connected to the first magnetic column 23 and the second magnetic column 24 on the corresponding second magnetic core 22. The primary winding 3 and the secondary winding 4 are respectively arranged on the first magnetic column 23 and the second magnetic column 24.

[0022] The technical solution of the utility model is to set up double magnetic columns in the magnetic core component 2 and adopt a skeleton-free process. Coils can be wound around the magnetic columns on both sides, so that the energy transmission efficiency is higher and the space of the transformer can be saved.

[0023] The number of turns in the primary winding 3 differs from the number of turns in the secondary winding 4. The primary winding 3 is the power input coil and typically has two turns. When AC current passes through the primary winding 3, it generates a magnetic field. These changing magnetic flux lines continuously exchange through the secondary winding 4, converting the magnetic energy into electrical energy. Because the secondary winding 4 has multiple turns, it outputs a high voltage, which is then supplied to the electrode assembly after voltage doubling and rectification.

[0024] In another embodiment, the PCB 1 is provided with a through hole 11, into which the primary winding 3 and the secondary winding 4 are respectively embedded. The pins at both ends of the primary winding 3 are connected to the controller of the electric flame cooker, while the pins at both ends of the secondary winding 4 are connected to the voltage-doubling rectifier of the electric flame cooker. The pins of the primary winding 3 and the secondary winding 4 are respectively connected to the controller or the voltage-doubling rectifier via traces on the PCB 1.

[0025] like Figure 1 As shown, the transformer for the electric flame stove also includes a fixing member 5 for securing the first magnetic core 21 and the second magnetic core 22. The fixing member 5 is made of an insulating material and can be annular or "C"-shaped. The fixing member 5 can be a high-temperature resistant bandage, tape, or other clamping member. The fixing member 5 fixes the PCB board 1, the magnetic core assembly 2, the primary winding 3, and the secondary winding 4 into a single unit. The transformer of the utility model is significantly reduced in size, which facilitates the circuit layout within the electric flame stove. It allows for the arrangement of multiple transformers within the electric flame stove, simplifies assembly, reduces material costs, and also reduces labor and manufacturing costs.

[0026] It will be apparent 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 essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
