Description

Technical Field

[0001] This utility model relates to the field of electric stove technology, and in particular to a plasma generating component and an electric stove. Background Technology

[0002] Existing electric stoves that heat by generating plasma use a rotating airflow to drive the electric arc inside the nozzle in order to prevent excessive voltage at the arc ignition point from damaging the nozzle or plasma needle. The rotation of the airflow is achieved by setting through holes on the side wall of the cyclone groove connecting the nozzle and the plasma needle. These through holes extend from the outer side wall of the cyclone groove to the inner side wall. However, since the fan supplying the air is located below the plasma generating component, a lot of air is lost during the process from generation to entering the nozzle. In addition, the thickness of the cyclone groove is limited, which limits the length of the through hole. The acceleration obtained by the airflow rotating and accelerating in the through hole is small, making it difficult to blow the electric arc after entering the nozzle. Utility Model Content

[0003] In view of this, the present invention provides a plasma generating component and an electric stove to solve the problems of small air volume, slow speed, and difficulty in blowing electric arc in the prior art.

[0004] To achieve one or more of the above objectives or other objectives, this utility model proposes a plasma generating assembly, including a nozzle, a plasma needle, and a cyclone trough;

[0005] The nozzle has a cylindrical structure, the cyclone groove is connected to the bottom end of the nozzle and forms an air cavity with the inner side wall of the nozzle, and one end of the plasma needle protrudes from the bottom wall of the cyclone groove and is located in the air cavity;

[0006] The outer wall of the cyclone trough is provided with a number of spiral grooves, which extend from the bottom wall of the cyclone trough to the upper wall of the cyclone trough, and the air cavity is connected to the outside through the spiral grooves.

[0007] Furthermore, several of the spiral grooves are circumferentially distributed.

[0008] Furthermore, the spiral grooves are provided with 4-8.

[0009] Furthermore, a limiting tube is provided on the bottom wall of the cyclone groove, through which the plasma needle passes.

[0010] Furthermore, the inclination angle of the spiral groove is 30-75°.

[0011] Furthermore, the outer wall of the nozzle is provided with a retaining ring extending upward at its top.

[0012] Furthermore, a hollow cylinder is connected to the bottom of the nozzle, and the hollow cylinder is threadedly connected to the outer wall of the cyclone groove.

[0013] To achieve one or more of the above objectives or other objectives, this utility model also proposes an electric stove, which includes the plasma generating component described in any of the above claims.

[0014] Implementing the embodiments of this utility model will have the following beneficial effects:

[0015] After adopting the above-mentioned plasma generating components, since the spiral groove is located on the side wall of the cyclone groove and its length is greater than the height of the side wall of the cyclone groove, the wind can obtain higher acceleration as it flows through the spiral groove. In addition, since the spiral groove extends upward from the bottom wall of the cyclone groove, the wind is less obstructed and less lost as it enters the spiral groove, resulting in a larger flow rate and velocity of the wind that can enter the wind cavity, making it easier to blow the electric arc.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings of this invention are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.

[0026] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0027] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0028] Reference Figures 1 to 4 This utility model proposes a plasma generating assembly, including a nozzle 1, a plasma needle 2, and a cyclone groove 3; the nozzle 1 has a cylindrical structure, the cyclone groove 3 is connected to the bottom end of the nozzle 1 and forms a wind cavity with the inner side wall of the nozzle 1, one end of the plasma needle 2 passes through the bottom wall of the cyclone groove 3 and is located in the wind cavity; a plurality of spiral grooves 31 are provided on the outer side wall of the cyclone groove 3, the spiral grooves 31 extend from the bottom wall of the cyclone groove 3 to the upper wall of the cyclone groove 3, and the wind cavity is connected to the outside through the spiral grooves 31.

[0029] In this embodiment, any horizontal cross-section of the spiral groove 31 is a portion of an ellipse or a portion of a circle. Each spiral groove 31 has two openings: an air inlet 311 located on the outer side of the bottom wall of the cyclone groove 3, communicating with the outside; and an air outlet 312 located on the upper wall of the cyclone groove 3, communicating with the air cavity. Several spiral grooves 31 are circumferentially distributed. There are 4-8 spiral grooves 31, preferably 6 or 8, equidistantly distributed on the cyclone groove 3.

[0030] Since the spiral groove 31 is located on the side wall of the cyclone groove 3 and its length is greater than the height of the side wall of the cyclone groove 3, the wind can obtain higher acceleration as it flows through the spiral groove 31. In addition, since the spiral groove 31 extends upward from the bottom wall of the cyclone groove 3, the wind is less obstructed and less lost as it enters the spiral groove 31, resulting in a larger flow rate and velocity of the wind that can enter the wind cavity, making it easier to blow the electric arc.

[0031] In some embodiments, the inclination angle of the spiral groove 31 is 30-75°. This inclination angle refers to the angle with respect to the horizontal direction. When this angle is too large, the spiral groove 31 is nearly vertical and shorter, allowing a larger volume of air to enter the air cavity, but the acceleration of the air within the spiral groove 31 is smaller. When this angle is too small, the spiral groove 31 is nearly parallel and longer, resulting in greater resistance and loss of airflow through the spiral groove 31. Therefore, the inclination angle of the spiral groove 31 is set between 30-75°, preferably 40°, 45°, 60°, etc.

[0032] In some embodiments, a limiting tube 32 is also provided on the bottom wall of the cyclone groove 3, through which the plasma needle 2 passes. Both the cyclone groove 3 and the limiting tube 32 are made of insulating materials, such as ceramic or mica. The plasma needle 2 includes a plasma head 21 and a plasma rod 22, with only the plasma head 21 located inside the air cavity. The limiting tube 32 is sleeved on the outside of the plasma rod 22, so that the arc ignition point is located as close as possible to the plasma head 21 and the nozzle 1.

[0033] In some embodiments, a retaining ring 11 extends upward from the top of the outer wall of the nozzle 1. For example, the retaining ring 11 is 2-10 mm high. More specifically, for example, 3 mm, 4 mm, or 5 mm. The thickness of the retaining ring 11 is 1 / 5 to 1 / 2 of the thickness of the top of the nozzle 1. Thus, a stepped structure is formed inside the nozzle 1 and at the top.

[0034] After the baffle ring 11 is set, the height of the nozzle 1 is actually higher. There is a stepped structure inside the nozzle 1 and at the top. The airflow inside the nozzle 1 forms a vortex and rotates. The electric arc rotates with the vortex and eventually can only reach the step inside the nozzle 1. The sound is only inside, and the actual noise is reduced.

[0035] A hollow cylinder is connected to the bottom of nozzle 1, and this hollow cylinder is threaded to the outer wall of cyclone groove 3. The threaded connection facilitates assembly and disassembly.

[0036] This utility model also proposes an electric stove, which includes the aforementioned plasma generating component.

[0037] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this utility model. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments, or make equivalent substitutions for some of the technical features. Any equivalent structures made using the content of this utility model specification and drawings, directly or indirectly applied to other related technical fields, are similarly within the patent protection scope of this utility model.
