Detailed Description
The present invention is illustrated by the following examples, but the present invention is not limited to these examples. Modifications to the embodiments of the utility model or equivalent substitutions of parts of technical features without departing from the spirit of the utility model are intended to be covered by the scope of the claims of the utility model.
The first embodiment is as follows:
a fire cover comprises a fire cover body 1, wherein a gas mixing cavity 2 is formed in the fire cover body 1, a main fire hole 3 is formed in the fire cover body 1, the main fire hole 3 comprises a gas inlet 31 and a gas outlet 32, the gas inlet 31 is communicated with the gas mixing cavity 2, the gas outlet 32 is communicated with the outer wall of the fire cover body 1, the central line of the gas inlet 31 is in the same straight line with the central line of the gas outlet 32, and the diameter of the gas outlet 32 is larger than that of the gas inlet 31.
The utility model provides a fire cover, which solves the problems of unstable smoke and insufficient utilization of partial fuel gas caused by the additional flame stabilizing fire holes or fire grooves for stable combustion of the conventional fire cover. Thereby further improving the thermal efficiency.
The ratio of the opening diameter to the opening depth of the air inlet 31 is a, and a is less than 1.2. The opening depth is a depth in the axial direction of the intake port 31. Through the ratio of the opening diameter and the opening depth of the limited air inlet 31, the opening diameter is matched with the opening depth, the phenomenon that the opening diameter is too large or too small is avoided, and the smooth air inlet is ensured.
The ratio of the opening diameter to the opening depth of the air outlet 32 is b, and b is less than 2. The opening depth is a depth in the axial direction of the air outlet 32. Through the ratio of the opening diameter and the opening depth of limiting the air port 32, the opening diameter is matched with the opening depth, the phenomenon that the opening diameter is too large or too small is avoided, and the smooth air outlet is guaranteed.
The diameter of the hole is narrowed at the connection of the air outlet 32 and the air inlet 31 to form that the diameter of the air outlet 32 is larger than that of the air inlet 31.
In the present embodiment, the diameter of the air outlet 32 is constant. The aperture of the inlet 31 is constant.
In other embodiments, the aperture size of the air inlet 31 may gradually increase from one end close to the air mixing chamber 2 to one end close to the outer wall of the fire cover body, the aperture size of the air outlet 32 may gradually increase from one end close to the air mixing chamber 2 to one end close to the outer wall of the fire cover body, but the aperture is still narrowed at the connection between the air outlet 32 and the air inlet 31, and a step is formed at the connection between the air outlet 32 and the air inlet 31.
The main fire hole 3 is arranged from one end close to the gas mixing cavity 2 to one end close to the outer wall of the fire cover body 1 in an upward inclined mode. The main fire hole 3 is arranged in an upward inclined manner from inside to outside, so that output air flow is sprayed upwards, and the combustion effect is further ensured. The included angle between the main fire hole 3 and the horizontal plane is c, and c is larger than 10 degrees and smaller than 80 degrees. The phenomenon that the air flow cannot be sprayed upwards due to the fact that the inclination angle of the main fire hole 3 is too low is avoided; also avoid main fire hole 3 inclination too big, cause the air current perpendicular upwards to spout, guarantee the combustion effect. The main fire holes 3 are circumferentially distributed on the fire cover body 1 at intervals. So that the periphery of the fire cover can uniformly spray air flow to ensure the combustion effect.
The aperture of the air inlet 31 is 0.6-1 cm.
The aperture of the air outlet 32 is 0.8-1.5 cm.
Example two:
a burner comprises the fire cover. The problems of unstable smoke and partial gas which are caused by the additional flame stabilizing fire holes or fire grooves of the prior burner for stable combustion are solved. Thereby further improving the thermal efficiency of the gas range burner.
The above preferred embodiments should be considered as examples of the embodiments of the present application, and technical deductions, substitutions, improvements and the like similar to, similar to or based on the embodiments of the present application should be considered as the protection scope of the present patent.
