[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0025] Therefore, the detailed description of the embodiments of this application provided below with reference to the accompanying drawings is intended merely to illustrate selected embodiments of this application and is not intended to limit the scope of protection claimed by this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0026] It should be understood that in the description of the embodiments of this utility model, the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of the embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0027] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows for mutual communication; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this utility model according to the specific circumstances.

[0028] like Figure 1 As shown, this utility model provides a plasma needle, including a plasma head (not shown in the figure), a support rod 2, and an electrical connector 1.

[0029] The top of the support rod 2 is connected to the plasma head, and the bottom of the support rod 2 is connected to the electrical connector 1.

[0030] The electrical connector 1 is provided with a patch nut 3, and the support rod 2 is connected to the electrical connector 1 through the patch nut 3.

[0031] The plasma needle provided by this utility model differs from commercially available designs that directly weld the support rod 2 to the electrical connector 1. It employs a patch nut 3, which is fixed to the electrical connector 1, and the support rod 2 is detachably connected to the patch nut 3. When the support rod 2 needs to be replaced, it can be directly removed from the patch nut 3. Installation and disassembly are very convenient and will not damage the device. The design that welds the support rod 2 to the electrical connector 1 requires welding every time the support rod 2 is replaced, which is cumbersome and can cause other solder joints to loosen during the replacement process.

[0032] like Figure 4 As shown, the electrical connector 1 can be a PCB board, and the PCB board is provided with mounting holes 101 for mounting the patch nut 3.

[0033] like Figure 2 , Figure 3 As shown, the patch nut 3 includes a nut body 301, an internal threaded hole 302 is provided on the top of the nut body 301, and a boss 303 is provided on the bottom of the nut body 301. The boss 303 is inserted into the mounting hole 101 and protrudes from the bottom of the PCB board.

[0034] Specifically, during installation, first insert the boss 303 into the mounting hole 101, then weld the exposed part of the boss 303 to ensure that the patch nut 3 is firmly connected to the PCB board, and then screw the support rod 2 into the internal thread hole 302.

[0035] Optionally, the support rod 2 is a smooth rod-shaped structure, with a first threaded end 201 and a second threaded end 202 at both ends. The plasma head is connected to the support rod 2 through the first threaded end 201, and the second threaded end 202 is adapted to the internal threaded hole 302.

[0036] Specifically, the support rod 2 is provided with a first threaded end 201 and a second threaded end 202 at both ends, that is, both ends of the support rod 2 are connected to the plasma head and the patch nut 3 respectively through threaded connection. This connection method makes it convenient to disassemble and install the support rod 2 when it is replaced.

[0037] Optionally, multiple support rods are arranged in three concentric layers. The first layer of support rods is located in the middle of the PCB board and is arranged in a square shape. The second and third layers of support rods are arranged in concentric circles.

[0038] like Figure 2As shown, the distribution of the support rods 2 is consistent with the distribution of the bosses 303. In this embodiment, the support rods 2 are divided into three layers. The innermost layer has four support rods 2 arranged in a square. The middle and outermost layers are arranged in concentric circles, with the center of the concentric circles coinciding with the center of the innermost square. In actual design, the spacing between each layer needs to be considered to ensure uniform heating of the cookware by the plasma.

[0039] This invention also provides a burner head assembly, which includes the aforementioned plasma needle. The burner head assembly also includes at least a high-voltage transformer (not shown in the figure), which is connected to an electrical connector 1 and used to provide high voltage to the plasma head capable of breaking down air to generate plasma. After prolonged use, the plasma needle of the burner head assembly needs to be replaced. The plasma needle designed above allows for convenient installation and disassembly during replacement, and the detachable connection method will not damage the burner head assembly.

[0040] This utility model also provides an electric flame stove, which uses the aforementioned plasma needle.

[0041] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
