Description

Technical Field

[0001] This utility model relates to the field of electric gas stove technology, and in particular to a cyclone tube. Background Technology

[0002] An electric gas stove is a type of cooker that generates high-temperature plasma, similar to a flame, by ionizing air with high voltage. Patent publication CN118189232A discloses a burner head and an electric gas stove. The burner head includes a top plate, a bottom shell, a ventilation assembly, a connecting ring, and several plasma generating components. The top plate and the bottom shell enclose a furnace cavity, which is connected to the ventilation assembly. The plasma generating components include a nozzle, a plasma needle, and a cyclone tube. The cyclone tube includes a main body and a connecting pipe, which is connected below the main body. The main body has an electrode hole that connects to the connecting pipe, and the plasma needle passes through the electrode hole and exits the connecting pipe. The top plate has several mounting holes, the nozzle connects to these holes, and the main body passes through the top plate and is connected inside the nozzle. The connecting pipe passes through the bottom shell, and the connecting ring is sleeved around the connecting pipe from below and abuts against the bottom shell.

[0003] The cyclone tube disclosed in the aforementioned patent is cylindrical. When the wind blows onto the side wall of the cyclone tube, the wind easily flows along the side wall, resulting in a small amount of effective airflow entering the cyclone tube, which affects the rotation effect of the plasma. Utility Model Content

[0004] In view of this, the present invention provides a cyclone tube to solve the problem of insufficient effective air volume entering the cyclone tube in the prior art.

[0005] To achieve one or more of the above objectives or other objectives, this utility model proposes a cyclone tube, including a cyclone groove and a connecting pipe;

[0006] The connecting pipe passes through the bottom wall of the cyclone channel. The cyclone channel is a hollow prism. Several air ducts are provided on the side wall of the cyclone channel. The air ducts include a connected air inlet and an air outlet. The air inlet is located on the outer side wall of the prism, and the air outlet is located on the inner side wall of the prism.

[0007] Furthermore, the cyclone groove is a straight prism.

[0008] Furthermore, the cyclone groove is a regular heptagonal prism.

[0009] Furthermore, the angle between the inclination angle of any of the aforementioned air ducts and the plane containing the outer wall of the cyclone trough is 45-60°.

[0010] Furthermore, the air inlet is circular or elliptical.

[0011] Furthermore, the air outlet is teardrop-shaped.

[0012] Furthermore, the height of the air outlet is higher than the height of the air inlet.

[0013] Furthermore, the projection of the air outlet onto the plane of the outer wall of the cyclone tube does not overlap with the air inlet.

[0014] Furthermore, the top of the cyclone groove is provided with threads.

[0015] Furthermore, the cyclone tube is made of insulating material.

[0016] Implementing the embodiments of this utility model will have the following beneficial effects:

[0017] After adopting the above-mentioned cyclone tube, since the cyclone slot is set as a prism, when the wind blows to the side wall of the prism, the flat surface can reflect more wind than the curved surface. The reflected wind is more likely to enter the air inlet on the side wall, allowing more wind to enter the cyclone tube and improving the efficiency of rotating plasma. Attached Figure Description

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 3 This utility model proposes a cyclone tube, including a cyclone groove 1 and a connecting pipe 2;

[0029] The connecting pipe 2 passes through the bottom wall of the cyclone trough 1. The cyclone trough 1 is a hollow prism. Several air ducts are provided on the side wall of the cyclone trough 1. The air ducts include a connected air inlet 3 and an air outlet 4. The air inlet 3 is located on the outer side wall of the prism, and the air outlet 4 is located on the inner side wall of the prism.

[0030] In this embodiment, the electric gas stove generates plasma by ionizing the air between the electrode needle and the electrode cylinder, and then heats the cookware placed above the electrode cylinder. After power is applied, the electrode needle is electrically connected to one pole of the power supply, and the electrode cylinder is electrically connected to the other pole. The electrode needle and electrode cylinder are assembled via a cyclone tube. Specifically, the connecting tube 2 is used to connect the electrode needle, which can pass through the hollow connecting tube 2 and be fixed in place. The top end of the cyclone groove 1 is threaded, and the electrode cylinder is threadedly connected to the cyclone groove 1. A portion of the connecting tube 2 is located inside the cyclone groove 1, and another portion is located outside the cyclone groove 1. Its length is similar to the length of the electrode needle, which protects the electrode needle. Simultaneously, because the electrode head of the electrode needle is larger than the hollow hole in the connecting tube 2, it is confined to the top end of the connecting tube 2, i.e., located inside the cyclone groove 1.

[0031] When the electric gas stove is working, the air enters the interior of the cyclone duct 1 through the air inlet 3 on the outer wall of the cyclone duct 1. Because the air duct has a certain inclination angle, the direction of the air when entering the nozzle is at an angle to the vertical direction. Several streams of air converge in the cyclone duct 1 to form a cyclone, which drives the plasma to rotate, thus avoiding the generation of plasma only in a specific location and the high voltage puncturing the electrode needle or electrode ring.

[0032] In this embodiment, taking any outer wall as an example, part of the airflow can directly enter the cyclone tube through the air inlet 3, while the other part of the airflow will hit the outer wall. Since the outer wall is a plane, the airflow will be reflected by the outer wall as a reflective surface. Because the normal of the reflection is perpendicular to the reflective surface, the reflected airflow will still be located on one side of the outer wall. After multiple reflections, it is easier for the airflow to re-enter the cyclone tube through the air inlet 3, thus ensuring that most of the airflow enters the cyclone tube and improving the efficiency of blowing the plasma. This avoids the situation where the outer wall is curved, resulting in a larger incident angle and the airflow being more easily reflected to a position farther away from the air inlet 3.

[0033] Understandably, the cyclone trough 1 can also be a square prism, pentagonal prism, or octagonal prism. The closer the prism is to a cylinder, the easier it is for air to escape. The fewer the number of edges of the prism, the fewer the number of air ducts, resulting in lower efficiency of air entering the cyclone tube. Preferably, setting the cyclone trough 1 as a regular prism allows air to enter the cyclone tube evenly.

[0034] In this embodiment, the inner wall of the cyclone trough 1 is cylindrical. In different embodiments, it can also be set as a prism adapted to the outer wall. The air inlet 3 can be circular or elliptical, and the air outlet 4 is teardrop-shaped. Each air duct has a certain inclination angle relative to the side wall of the cyclone trough 1 it is located on, so that when the airflow exits the air duct, it has a certain slope on the horizontal plane. After multiple airflows converge, they can form a cyclone and drive the generated plasma to rotate and flow upward. Preferably, the position of the air outlet 4 can be higher than that of the air inlet 3 to facilitate the upward flow of air.

[0035] Reference Figure 3 Furthermore, the angle between the inclination angle of any air duct and the plane of the outer wall of the cyclone trough 1 is 45-60°. When this angle is close to 90 degrees, the wind blows into the cyclone tube almost vertically, making it difficult to rotate. When this angle is close to zero degrees, the wind blows into the cyclone tube and quickly hits the inner wall of the cyclone trough 1, which easily loses the kinetic energy of the wind and makes it difficult to converge with other winds. Therefore, the preferred angle is 45° to reduce losses.

[0036] In addition, to prevent conductivity between the electrode needle and the electrode cylinder, the cyclone tube is made of insulating material, such as ceramic or mica, which is both insulating and heat-resistant, preventing the high temperature of the plasma from affecting the service life of the electric gas stove.

[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.
