DETAILED DESCRIPTION

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of the present invention; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the terms "including" and "having" and any variations thereof in the specification and claims of the present invention and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of the present invention or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0027] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0028] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0029] Reference Figures 1 to 4 The present invention provides an electric stove nozzle, comprising: a fan 1, a base 2, a cyclone 3, a nozzle 4, a plurality of sub-nozzles 5, a plurality of sub-cyclones 6 and a plurality of sub-electrode needles 7;

[0030] The bottom of the base 2 is provided with an air inlet 21, the fan 1 is arranged at the air inlet 21, the nozzle 4 is arranged on the base 2 and a cavity is formed inside the base 2; the cyclone 3 is arranged at the bottom of the nozzle 4, and the inside of the nozzle 4 is connected with the cavity through the cyclone 3;

[0031] A plurality of sub-nozzles 5 are circumferentially distributed on the side wall of the nozzle 4. A sub-cyclone 6 is provided at the bottom of each sub-nozzle 5, and a sub-electrode needle 7 is inserted into each sub-cyclone 6; each sub-nozzle 5 is connected to the cavity through the sub-cyclone 6.

[0032] In this embodiment, the cyclone 3 and sub-cyclone 6 are components that convert the airflow passing through the cyclone 3 into a vortex airflow, with the purpose of making the two electrode arcing points in the plasma generating assembly, i.e., the nozzle, change with the rotation of the airflow, so as to avoid the arcing points being in the same position for a long time, causing the electrodes to be burned through, and at the same time, ejecting the generated plasma to form a "flame". The above-mentioned multiple sub-nozzles 5, multiple sub-cyclones 6 and multiple sub-electrode needles 7 constitute a sub-plasma generating assembly, and the principle is similar to the disclosure of publication number CN117663202A and other disclosures, and the relevant details are not repeated. The above-mentioned electric stove nozzle has a cavity formed inside the base 2, and the fan 1 blows the airflow into the cavity from the air inlet 21. The airflow in the cavity forms a vortex airflow through the cyclone 3 and blows into the nozzle 4. At the same time, the airflow in the cavity also forms a vortex airflow through multiple sub-cyclones 6 and blows into the corresponding sub-nozzles 5. The plasma formed by these sub-nozzles 5 and the corresponding sub-electrode needles 7 are all blown into the nozzle 4, and finally a large plasma "flame" is formed from the nozzle 4 and sprayed out. When attached to the pot, this large plasma "flame" is sprayed onto the pot and dispersed to cover the bottom, and the effect is comparable to that of a gas stove burning. Compared with the plasma flames generated by the electric stoves on the market, which are all dispersed in multiple "small fire columns" at the bottom of the pot, it effectively improves the uniformity of the pot temperature and improves the user experience. It is worth mentioning that the sub-electrode needle 7 can be connected to one pole of the power supply through a wire through a wiring hole opened in the base 2, and then the wiring hole can be sealed; the sub-nozzle 5 can be connected to the other pole of the power supply through the nozzle 4, that is, the nozzle 4, the sub-nozzle 5 and the top of the base 2 are all set to metal material, such as stainless steel, and the other pole of the power supply is connected to any screw hole position on the top of the base 2.

[0033] In some embodiments, the nozzle 4 includes: a nozzle seat 41 and a nozzle cover 42. The bottom of the nozzle seat 41 is provided with a connection hole for connecting to the cyclone 3. The top of the nozzle cover 42 has a flame outlet. A plurality of sub-nozzles 5 are circumferentially distributed on the side wall of the nozzle seat 41.

[0034] In this embodiment, after the nozzle seat 41 and the nozzle cover 42 are connected, a cavity is formed inside. Preferably, the opening of the cavity gradually becomes smaller in the direction toward the flame outlet. For example, the cross section of the nozzle seat 41 decreases from the first connecting ring 411 to the connecting hole, and the cross section of the nozzle cover 42 decreases from the first connecting ring 411 to the flame outlet. Figure 2According to Bernoulli's principle, this can speed up the airflow and allow the "plasma flame" to spray higher, ensuring good thermal efficiency when using different pots and enhancing the user experience.

[0035] In some embodiments, the nozzle seat 41 is provided with a first connecting ring 411 , and the nozzle cover 42 is provided with a second connecting ring 421 , and the first connecting ring 411 and the second connecting ring 421 are sealed and connected.

[0036] In this embodiment, the nozzle seat 41 is sealed and connected by a first connecting ring 411 and a second connecting ring 421 provided on the nozzle cover 42, which is easy to assemble, and the contact area between the first connecting ring 411 and the second connecting ring 421 is large, so the sealing effect is good.

[0037] In some embodiments, the cyclone 3 is cylindrical and has a side wall with a plurality of inclined holes 31. For example, the plurality of inclined holes 31 are arranged in groups of four along the axial direction of the cyclone 3, and the side wall of the cyclone 3 has nine groups of inclined holes 31 distributed circumferentially.

[0038] In this embodiment, the inclined holes 31 are holes that are perpendicular to the axis of the cyclone 3 from the side wall of the cyclone 3. The inclined holes 31 have a certain angle, and the inclined holes 31 are arranged clockwise or counterclockwise, such as Figure 4 shown.

[0039] In some embodiments, the electric stove nozzle also includes: a cyclone connecting column 8, the base 2 is provided with a connecting plate 23 through a rib 22 at the air inlet 21, one end of the cyclone connecting column 8 is connected to the connecting plate 23, and the other end is connected to the bottom of the cyclone 3.

[0040] In this embodiment, since the cyclone 3 is usually made of high-temperature resistant insulating material and the nozzle 4 is made of metal material, it is rather troublesome to connect the two. A connecting column is provided to, on the one hand, provide a supporting force for the cyclone 3 to facilitate the connection between the cyclone 3 and the nozzle 4, and on the other hand, the connecting column can be set to be smaller in size, especially with a smaller cross-section than the cyclone 3, occupying a smaller position of the air inlet 21, and hardly affecting the air intake of the air inlet 21.

[0041] In some embodiments, the electric stove nozzle further includes: an electrode needle 9, which passes through the cyclone 3 and the cyclone connecting column 8 in sequence and is plugged into the connecting plate 23. Specifically, the electrode needle 9 is formed by connecting a needle rod 91 and a needle head 92, and the needle head 92 is formed by connecting a cylinder and an inverted cone;

[0042] The needle 92 and the nozzle 4 or the sub-nozzle 5 can generate plasma.

[0043] In this embodiment, in addition to the above-mentioned multiple sub-nozzles 5, multiple sub-cyclones 6 and multiple sub-electrode needles 7 forming a sub-plasma generating assembly, an electrode needle 9 can also be set inside the nozzle 4, and the electrode needle 9 and the nozzle seat 41 or the nozzle cover 42 form a plasma generating assembly to enhance the generation of "plasma flame" and thus enhance the firepower. It is worth mentioning that in addition to the above-mentioned multiple sub-nozzles 5 are circumferentially distributed on the side wall of the nozzle 4, multiple sub-nozzles 5 can also be circumferentially distributed on the side wall of the nozzle 4, which further enhances the generation of "plasma flame" and is suitable for scenes with higher firepower requirements. For example, the form of setting a circle of nozzles 5 is suitable for home use, and the form of setting multiple circles of nozzles 5 is more suitable for commercial use such as restaurants or industrial use such as high-temperature calcination.

[0044] The present invention also provides an electric fire stove, which comprises any one of the above-mentioned electric fire stove nozzles.

On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.
