[0020] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] like Figure 1 , Figure 2 , Figure 3As shown, a fire cover comprises a hollow annular main body 1 with an opening at the bottom, the annular main body 1 comprises an inner ring wall plate 2, an outer ring wall plate 3 and a top annular plate 4, a radial protrusion 41 and a plurality of concentric annular combustion grooves 42 are provided on the inner surface of the top annular plate 4, and the annular combustion groove 42 and two adjacent radial protrusions 41 form a radial gas groove 43 to communicate with each other. With such a structure, the gas and air mixture enters the annular main body 1, and then enters the radial gas groove 43, and the gas is burned in the annular combustion groove 42 to form a plurality of circular flames.

[0023] like Figure 3 , Figure 4 , Figure 5 As shown, the top circular ring plate 4 is in the shape of a truncated cone, and the angle α between the annular combustion groove 42 and the generatrix of the top circular ring plate 4 is greater than or equal to 90 degrees.

[0024] The present invention can also be implemented as follows: the top circular ring plate 4 is planar, and the annular combustion groove 42 is perpendicular to the top circular ring plate 4, or has an acute angle with a horizontal plane on the radial outer side.

[0025] The present invention can also be implemented as follows: the top circular ring plate 4 is in an inverted truncated cone shape, and the annular combustion groove 42 is perpendicular to the generatrix of the top circular ring plate 4. With such a design, the flames are arranged in a ladder configuration, and the flame area is large.

[0026] The radial protrusion 41 and the circular ring body 1 are integrally formed, and the circular ring combustion groove 42 is formed by machining. Since the circular ring combustion groove 42 is arranged on the top circular ring plate, the machining is convenient and the work efficiency is high.

[0027] As a further improvement of the present invention: an inverted frustum-shaped shoulder 5 is provided at the intersection of the inner ring wall plate 2 and the top circular ring plate 4.

[0028] An ignition hole 51 is provided on the truncated cone-shaped shoulder 5 , and the ignition hole 51 is communicated with the radial gas groove 43 .

[0029] When the present invention is used, the gas amount is adjusted by the gas regulating valve on the stove to adjust the power size, and stir-frying is achieved when the firepower is at maximum.
