[0020] The following describes embodiments of the present invention in detail. Examples of the embodiments 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 intended only to explain the present invention and are not to be construed as limiting the present invention.

[0021] In the description of this utility model, it should be noted that, 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 connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0022] like Figure 1 、 Figure 2 、 Figure 3As shown, a fire cover comprises a hollow, bottom-opening annular body 1. The annular body 1 comprises an inner ring wall plate 2, an outer ring wall plate 3, and a top annular plate 4. The inner surface of the top annular plate 4 is provided with radial protrusions 41 and a plurality of concentric annular combustion grooves 42. The annular combustion grooves 42 and two adjacent radial protrusions 41 form radial gas grooves 43 that communicate with each other. With this structure, a mixture of gas and air enters the annular body 1 and then enters the radial gas grooves 43, where the gas is burned 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 a truncated cone shape, 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 forms an acute angle with a horizontal plane on the radial outer side.

[0025] The present invention can also be implemented in this way: the top circular plate 4 is in the shape of an inverted truncated cone, and the annular combustion groove 42 is perpendicular to the generatrix of the top circular plate 4. With such a design, the flames are arranged in a ladder 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 provided on the top circular ring plate, machining is convenient and has high work efficiency.

[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 utility model is used, the gas amount is adjusted by the gas regulating valve of the stove, thereby adjusting the power size, and stir-frying is achieved when the firepower is at maximum.

[0030] Throughout this specification, reference to terms such as "one embodiment," "some embodiments," "illustrative embodiments," "examples," "specific examples," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with that embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the illustrative use of the above terms does not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.
