[0027] 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 application; 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 application; the terms "including" and "having" and any variations thereof in the specification and claims of the present application 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 application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0028] 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 application. The appearance of the phrase in various locations 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.

[0029] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0030] Reference Figures 1 to 5The present application proposes a cyclone tube, which is used for the burner head of an electric stove, and includes a cyclone tube body 1 and a connecting tube 2. The connecting tube 2 is connected to the cyclone tube body 1. The cyclone tube body 1 has an electrode hole 3 connected to the connecting tube 2, and the electrode hole 3 is used to connect a plasma needle. The cyclone tube body 1 and the connecting tube 2 are integrally formed, and the central axis of the connecting tube 2 coincides with the central axis of the cyclone tube body 1. The connecting tube 2 is provided with a thread, and the thread is used to connect the furnace cavity bottom shell. Specifically, the thread is connected to a limit ring, and the limit ring is an annular structure with an internal thread and a clamping ring at the lower end. The cyclone tube passes through the furnace cavity of the burner head, and the furnace cavity is surrounded by a furnace cavity top plate and a furnace cavity bottom shell. The connecting tube 2 passes through the furnace cavity bottom shell and passes out. The limit ring is sleeved on the connecting tube 2 from below and abuts against the lower surface of the furnace cavity bottom shell through the clamping ring. In this embodiment, the connecting tube 2 includes an upper connecting tube 21 and a lower connecting tube 22, and the outer diameter of the upper connecting tube 21 is greater than the outer diameter of the lower connecting tube 22. A thread is arranged on the upper end of the lower connecting tube 22, and the lower connecting tube 22 is inserted into the limiting ring. The lower surface of the upper connecting tube 21 abuts against the upper surface of the limiting ring, and the limiting ring is clamped with the lower surface of the furnace chamber bottom shell. Since the outer diameter of the upper connecting tube 21 is larger, the limiting ring limits the downward movement of the connecting tube 2, and the limiting ring is fixed on the furnace chamber bottom shell from bottom to top, so that the position of the connecting tube 2 is fixed.

[0031] When the electric stove is in use, the plasma needle passes through the electrode hole 3 and comes out, the cyclone tube body 1 and the connecting tube 2 are sleeved outside the plasma needle, the cyclone tube body 1 is connected to the nozzle, the nozzle is electrically connected to one pole of the power supply, and the plasma needle is electrically connected to the other pole of the power supply. After the power supply is turned on, the air between the nozzle and the plasma needle is ionized, and high-temperature plasma is generated inside the nozzle. The pot is placed above the burner, and the plasma heats the pot.

[0032] In this embodiment, a thread is provided on the outside of the cyclone tube body 1, and the thread is used to connect the nozzle. The electrode hole 3 is a columnar hole, extending from the upper surface of the cyclone tube body 1 to the lower surface of the connecting tube 2. Specifically, the plasma needle includes a plasma rod and a plasma head. One end of the plasma rod is fixed to the plasma head through a threaded structure, and the plasma rod can just pass through the electrode hole 3. After assembly, the plasma head is located above the cyclone tube body 1, and the bottom end of the plasma head coincides with the upper surface of the cyclone tube body 1.

[0033] The plasma needle is a conductive material, and the high temperature will be conducted downward through the plasma needle, affecting the normal operation of other components in the electric stove, such as circuit boards and other structures. The cyclone tube body 1 and the connecting tube 2 are both surrounded by the outside of the plasma rod to play a role in heat insulation. Therefore, the cyclone tube is set to a high-temperature resistant material. In addition, since the plasma needle and the nozzle are assembled together through the cyclone tube, in order to avoid conduction between the plasma needle and the nozzle through the cyclone tube, the cyclone tube is set to an insulating material. Therefore, the cyclone tube is a high-temperature resistant insulating material, which can be a material such as ceramic or mica.

[0034] In this embodiment, the cyclone tube body 1 is similar to the cyclone tube in the prior art, including an upper boss 11 and a boss body 12. The cross-sectional area of ​​the upper boss 11 is smaller than the cross-sectional area of ​​the boss body 12, and the plasma head is fixedly arranged above the upper boss 11. When the electric stove is used, liquid may fall from the top of the cyclone tube onto the cyclone tube. Since the upper boss 11 makes the plasma head higher than the boss body 12, the liquid will flow onto the boss body 12 and will not contact the plasma head, causing a short circuit.

[0035] In addition, a plurality of through holes 13 are circumferentially distributed on the boss body 12, and the through holes 13 include a first opening 131 disposed on the upper surface of the boss body 12, a second opening 133 disposed on the lower surface of the boss body 12, and an oblique column hole 132 connecting the first opening 131 and the second opening 133. After the liquid falls on the boss body 12, it can flow out through the through holes 13. The projection of the first opening 131 on the lower surface of the boss body 12 does not overlap with the second opening 133. Both the first opening 131 and the second opening 133 are circular, and the area of ​​the first opening 131 is smaller than the area of ​​the second opening 133, and the connecting pipe 2 is located between the plurality of second openings 133.

[0036] Specifically, for the burner head of the present application, the boss body 12 includes a connecting block 121 and a fixing block 122. The connecting block 121 is provided with a thread for connecting the nozzle. The cross-sectional area of ​​the connecting block 121 is smaller than the cross-sectional area of ​​the fixing block 122. In different embodiments, the boss body 12 is set to be a cone with a smaller cross-sectional area at the top and a larger cross-sectional area at the bottom, which can also achieve a similar technical effect.

[0037] When the electric stove is working, wind enters the nozzle from the through hole 13 of the cyclone tube body 1 from bottom to top. Since the size of the first opening 131 is smaller than the second opening 133, the wind speed will gradually increase during this process, and the inclined column hole 132 makes the wind have an angle with the vertical direction when entering the nozzle. Several winds converge in the nozzle to form a cyclone, which drives the plasma to rotate in the nozzle, avoiding the generation of plasma only at a specific position and the high voltage breakdown of the plasma head or nozzle. When the electric stove is not ignited, for example, after cooking or when cleaning the countertop, soup or cleaning liquid is likely to enter the stove head. There are multiple plasma components, so the amount of liquid flowing into a certain nozzle will not be too much, and the upper boss 11 has a certain height. After the liquid flows into the nozzle, it will accumulate in the cavity formed by the upper boss 11, the nozzle and the connecting block 121, and then flow out from the through hole 13 from the first opening 131. The plasma head and at least a part of the nozzle are made of conductive material to avoid liquid accumulation in the nozzle, which can prevent a short circuit when the electric stove is powered on again, thereby improving the safety of the electric stove.

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