[0026] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0027] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0028] Furthermore, in the description of the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; internal communication between two components; and wireless or wired connections. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0029] In addition, the technical features involved in the different embodiments of the present invention described later can be combined with each other as long as they do not conflict with each other.

[0030] See also Figures 1 to 4 In an embodiment of the present invention, a novel furnace head includes a shell 1 and a plurality of plasma torches 2. The shell 1 is annular; the shell 1 includes an upper shell 11, a lower shell 12, an inner sidewall 13, and an outer sidewall 14, wherein the upper shell 11, the lower shell 12, the inner sidewall 13, and the outer sidewall 14 are coaxial around a central axis A.

[0031] like Figure 4-Figure 5 As shown, in this embodiment, the plasma torch 2 includes a flame tube 21, a ceramic tube 22, and an electrode needle 23. Multiple flame tubes 21 are circumferentially arranged on the inner sidewall 13, and the other end of each flame tube 21 extends through the inner sidewall 13 toward the central axis A. The multiple flame tubes 21 of the present invention spray plasma flames from different angles toward the coaxial line, effectively concentrating heat in the central area within the inner sidewall 13, avoiding the problem of local overheating or uneven heating caused by a single flame tube 21 directly heating the bottom of the pot.

[0032] When the interior of inner wall 13 is at a high temperature, the movement of air molecules intensifies and the distance between molecules increases due to the principle of thermal expansion and contraction. This reduces the number of air molecules within the same volume, resulting in a lower air density. This lower air density creates a density difference with the relatively denser air below. According to Archimedes' principle, a low-density object experiences an upward buoyancy force in a high-density fluid. The plasma flame itself is extremely hot, and in a region of low-density hot air, it experiences an upward buoyancy force and rises.

[0033] In another embodiment, a hearth 3 is mounted above the upper housing 11, leaving a gap between the hearth 3 and the wok. The lower portion of the lower housing 12 is also sealed to the air duct 4. The inner sidewall 13 communicates with the air duct 4 and the interior of the hearth 3, creating vertical convection. This allows the plasma flame, which creates thermal convection, to rise and better contact the pot placed above it, more evenly covering the bottom of the pot and ensuring a more uniform cooking process.

[0034] At the same time, in an embodiment of the present invention, the process of hot air rising and cold air replenishment forms a natural airflow circulation inside the air duct 4, the inner wall 13 and the furnace 3. Compared with the prior art that relies on the fan aerodynamic force to promote airflow circulation, the natural circulation method of the present invention makes the heat of the furnace 3 dissipate to the outside more slowly, and the heat stays in the furnace 3 for a longer time. Therefore, the present invention reduces heat loss and improves thermal efficiency.

[0035] In another embodiment, a ceramic tube 22 is arranged between the inner wall 13 and the outer wall 14, one end of the ceramic tube 22 is connected to the flamethrower 21, and the other end is connected to a connecting tube 24, and the other end of the connecting tube 24 extends outside the shell 1 through the outer wall 14; the connecting tube 24 is an insulator, usually made of ceramic material, and the connecting tube 24 insulates the electrode needle 23 and the shell 1 of the furnace head.

[0036] In another embodiment, an air intake fan 5 is also installed on the shell 1 to provide the pneumatic force required by the plasma torch 2 for the inner cavity of the shell 1. The ceramic tube 22 is provided with a plurality of air guide holes 221, which connect the inner cavity of the shell 1 and the interior of the plasma torch 2. The pneumatic force enables the plasma inside the plasma torch 2 to be better sprayed to the center position of the inner wall 13 of the furnace head.

[0037] like Figure 2 As shown, in another embodiment, the inner wall 13 is composed of an upper inner wall 111 and a lower inner wall 121, and the outer wall 14 is composed of an upper outer wall 112 and a lower outer wall 122; wherein the upper inner wall 111 and the upper outer wall 112 are respectively arranged on the inner ring circumference and the outer ring circumference of the upper shell 11, and the lower inner wall 121 and the lower outer wall 122 are respectively arranged on the inner ring circumference and the outer ring circumference of the lower shell 12; a plurality of semicircular first slots 100 are provided on the upper inner wall 111 The lower inner wall 121 is provided with a plurality of semicircular second slots 200 corresponding to the first slots 100, and one end of the flamethrower 21 is provided between the first slots 100 and the second slots 200; the upper outer wall 112 is provided with a plurality of semicircular third slots 300, and the lower outer wall 122 is provided with a plurality of semicircular fourth slots 400 corresponding to the third slots 300, and one end of the ceramic tube 22 is provided between the third slots 300 and the fourth slots 400.

[0038] The above is the structure of the burner shell 1 of the present invention, which is easy to install. The upper shell 11 is provided with an upper inner wall 111 and an upper outer wall 112, and the lower shell 12 is provided with a lower inner wall 121 and a lower outer wall 122. The upper inner wall 111 and the upper outer wall 112 are symmetrical with the lower inner wall 121 and the lower outer wall 122 respectively.

[0039] The present invention is assembled in the following specific steps:

[0040] S1. First, multiple plasma torches 2 are clamped between the lower inner wall 121 and the lower outer wall 122, wherein one end of the flame-spraying tube 21 is installed in the corresponding second slot 200, and the connecting tube 24 is installed in the corresponding fourth slot 400;

[0041] S2. Enclose the upper shell 11 and the lower shell 12, wherein the upper inner wall 111 and the upper outer wall 112 are respectively connected to the lower inner wall 121 and the lower outer wall 122, and the first slot 100 is clamped to the flamethrower 21, and the third slot 300 is clamped to the connecting tube 24;

[0042] S3, bolts are used to connect the upper shell 11 and the lower shell 12 to stabilize the plasma torch 2;

[0043] S4. Install the gas guide groove and the furnace 3. The furnace 3 can be set to be movably connected.

[0044] The structure of the present invention makes the burner head installation method simple.
