Description

Technical Field

[0001] The utility model relates to the technology of electric flame stove field, in particular to an electric flame component and an electric flame stove. Background Art

[0002] As a modern kitchen cooking equipment, the electric flame stove has unique advantages in practical use. Compared with the traditional gas stove, the electric flame stove does not need to rely on gas pipelines, but generates heat through electrical energy conversion, so it is safer and more reliable. In addition, the electric flame stove is easy to operate and quick to light a fire. At the same time, the electric flame stove also has a high energy utilization efficiency, which is of great significance to environmental protection and energy conservation.

[0003] Among them, the burner head of the electric flame stove is the most important part of the electric flame stove. The burner head is provided with an electric flame component, which is used to create an electric arc and transfer the heat of the arc to the pot body for stewing, steaming and frying.

[0004] In the prior art, such as Chinese patent CN219572014U, it discloses an electric flame heating device, including a conical fire outlet tube and a vortex device, and an inclined air inlet is arranged on the side wall of the vortex device. The inclined air inlet increases the difficulty of manufacturing the vortex device, and the deviation of the inclination angle is likely to affect the stability of the generated vortex, and its ion needle is installed in the vortex device by screw fixing, which is too cumbersome to assemble and has low assembly efficiency. In addition, its conical fire outlet tube is integrally formed on the burner head. Since the electric flame stove is generated by the principle of high-voltage electric arc, there is a certain strong oxidation effect, and the conical fire outlet tube is easily damaged after a period of use. Usually, a plurality of conical fire outlet tubes are arranged. Under this structure, all the conical fire outlet tubes need to be replaced, which increases the maintenance cost.

[0005] Furthermore, the electric flame stove in the prior art is usually grounded through a ground wire. If there is no ground wire in the household line, the high voltage of the electric flame stove may flow back to the human body, causing the risk of electric shock, and the safety is poor.

[0006] Therefore, it is necessary to design a new technical solution to solve the above problems. Utility Model Content

[0007] In view of this, the utility model aims to solve the deficiencies in the prior art, and its main purpose is to provide an electric flame assembly and an electric flame stove, wherein an electrode head is arranged on the top of the ion needle, and the electrode head comprises a vertical installation section, a tapered guide section which is small at the top and large at the bottom, and a vertical guide section which are connected in sequence from bottom to top, and cooperates with a flame outlet channel which comprises an air intake section, a first air guide section which is gradually reduced in size, a second air guide section which is gradually increased in size, and an air outlet section which are connected in sequence from bottom to top, and a plurality of air intake channels which are opposite to the tapered guide section are opened on the wall surface of the air intake section, and the air intake channel is arranged opposite to the tapered guide section, that is, the air intake channel is a straight inlet, so that the air intake channel is easy to process and manufacture, and then the nozzle is easy to generate and manufacture, and the wind flowing into the air intake channel enters the first air guide section which is gradually reduced in size after being guided by the tapered guide section and the vertical guide section, thereby forming a vortex in the first air guide section, and the structural design is ingenious.

The structural design is ingenious.

[0011] As a preferred solution, the air inlet passage is recessed upward from the bottom end of the nozzle.

The upper shell is connected to a grounding wire to form double grounding protection, which is safer.

[0018] As a preferred solution, a circuit board is provided in the stove body, and the lower shell is mounted on the top of the circuit board through a quick-release structure.
