[0023] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] Embodiment 1: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment provides a stainless steel fire cover, including a main body 1 in a circular shape, wherein the main body 1 includes a top wall 11, an outer side wall 12 extending vertically downward from the outer edge of the top wall 11, an upslope surface 13 inclined downward from the inner edge of the top wall 11 from the outside to the inside, and an inner side wall 14 extending vertically downward from the inner edge of the upslope surface 13, and a gas chamber 100 with an open bottom is formed between the top wall 11, the outer side wall 12, the upslope surface 13 and the inner side wall 14, and the top wall 11 is provided with a gas chamber 100 having a gas chamber 100 having a gas chamber 100 having a gas chamber 100 having a gas chamber 100 disposed in a circular shape. The top surface of the wall 11 is inclined downward from the outside to the inside, and a plurality of groups of fire holes 15 spaced apart along the circumferential direction are provided on the outer wall 12. The fire holes 15 are located above the middle of the outer wall 12, and a drainage trough 16 is formed in a depression on the top wall 11 above each group of the fire holes 15. Fire starter grooves 17 are respectively provided on both sides of the drainage trough 16, and fire starter holes 18 spaced apart are provided at the inner end of the fire starter groove 17 and at a position close to its inner edge on the upslope surface 13.

[0025] The stainless steel fire cover provided in this embodiment can reduce the occurrence of clogging of the ignition groove. Specifically, the additional drainage groove 16 can drain the burning materials, dirt and sewage that fall to the top surface of the main body 1, thereby avoiding the ignition groove 17 from being blocked. Furthermore, the top surface of the top wall 11 is tilted downward from the outside to the inside, which is more conducive to draining the burning materials, dirt and sewage that fall to the top surface of the main body 1, further avoiding the occurrence of clogging of the ignition groove 17, thereby achieving the purpose of ensuring the normal use of the fire cover and the combustion efficiency of the fire cover.

[0026] During installation, the position between two adjacent groups of fire holes 15, the bottom of the fire cover and the support position of the pot rack are arranged relative to each other, so that the fire cover is left empty and does not burn the pot rack, thereby reducing the flames of the fire holes 15 from burning the support of the pot rack, resulting in insufficient combustion of the gas and increased smoke. The flames of the fire holes 15 avoid the pot rack to achieve the effect of energy saving and reducing smoke.

[0027] In this embodiment, the bottom wall of the drain trough 16 is inclined downward from the outside to the inside, and the two side walls of the drain trough 16 are inclined from the top to the bottom. The ignition groove 17 is arranged on the side wall of the drain trough 16, and its structure is simple, so that the burning materials, dirt and sewage that fall into the ignition groove 17 or the drain trough 16 can be discharged smoothly, avoiding the ignition groove 17 from being blocked.

[0028] Furthermore, each group of the fire holes 15 includes an upper fire hole 151 and a lower fire hole 152, wherein the upper fire hole 151 includes a plurality of upper fire holes distributed at intervals, and the lower fire hole includes a plurality of lower fire holes distributed at intervals, the upper fire holes and the lower fire holes are distributed at intervals, and the aperture of the lower fire hole is larger than the aperture of the upper fire hole, the diameter of the lower fire hole is 1.8-2.0mm, and the diameter of the upper fire hole is 1.4-1.6mm. Compared with the existing fire cover, the combustion efficiency can be improved by at least 5%-10%, which can make the combustion of the gas more complete and more efficient.

[0029] In this embodiment, the ignition groove 17 is tilted downward, and the tilt angle is 50°-70°. The above design improves the ignition and combustion efficiency of the fire cover.

[0030] Furthermore, the fire hole 15 is inclined upward from the inside to the outside, and the angle between the fire hole 15 and the horizontal plane is 30° to 35°. Compared with the existing fire cover, its combustion efficiency can be improved by at least 5%-10%, which can make the combustion of gas more complete and more efficient.

[0031] Furthermore, a step portion 120 is provided on the inner side of the bottom of the outer side wall 12, which has a simple structure and a reasonable and ingenious design. The above design facilitates the installation of the fire cover.

[0032] In this embodiment, the angle between the upslope surface 13 and the horizontal plane is 35° to 40°. It has a simple structure and a reasonable and ingenious design. The upslope surface 13 can have a certain buffering and diverting effect on the air, and can supplement secondary air for the gas combustion of the fire hole 15, thereby achieving the effect of improving the gas combustion efficiency and reducing smoke.

[0033] In this embodiment, a high temperature resistant coating is provided on the surface of the main body 1, so as to improve the working stability and safety of the fire cover and extend the service life of the fire cover.

[0034] Preferably, the main body 1 is forged by a stainless steel plate, and the stainless steel plate can be SUS304, SUS316, SUS201, SUS430 or SUS409L, and the thickness of the stainless steel plate is 3.0 mm.
