Abstract
A fire cover for gas burner, comprises top board, radial internal ring wall, radial external annulus and outer ring interface, radial external annulus is provided with fire hole; The top surface distance being positioned at the top distance top board of the fire hole end of radial outside of described fire hole is 1-2 millimeter; Cylindrical or the truncated cone of the radial external annulus at the place of described fire hole outlet side.Owing to adopting such structure, during fire hole burning, form flame upwards, flame propagation speed, auxiliary air enters fast, and during burning, air is sufficient, and sufficient combustion, reaches the Energy Efficiency Ratio of national regulation.
Description
Technical field
The utility model relates to a kind of household gas burner, especially a kind of fire cover.
Background technology
Currently available technology, a kind of fire cover of gas burner, comprises top board, radial external annulus, radial internal ring wall and outer ring interface, radial external annulus is provided with fire hole; The upper end of described radial external annulus has along plate.Existing problems are: during fuel gas buring, and fire hole resistance is large, and auxiliary air is not enough, burns insufficient.
Utility model content
The purpose of this utility model is: the fire cover providing a kind of gas burner, its tool flame propagation speed, the feature of the sufficient sufficient combustion of auxiliary air.
The utility model is achieved in that a kind of fire cover of gas burner, comprises top board, radial internal ring wall, radial external annulus and outer ring interface, radial external annulus is provided with fire hole; Its special character is: the top surface distance being positioned at the top distance top board of the fire hole end of radial outside of described fire hole is 1-2 millimeter; Cylindrical or the truncated cone of the radial external annulus at the place of described fire hole outlet side.
The fire cover of described a kind of gas burner, its special character is: the axis of described fire hole and the angle of horizontal plane are 30-45 degree.
The fire cover of described a kind of gas burner, its special character is: the radially inner side of described top board is arc-shaped curved surface, radial outside is plane, and the distance being positioned at the radial edges of the plane of the top distance top board of the fire hole end of radial outside of described fire hole is 1-2 millimeter.
The fire cover of described a kind of gas burner, its special character is: described radial external annulus is truncated cone, and its coning angle is 9-30 degree.
The fire cover of described a kind of gas burner, its special character is: the described inner surface of radial external annulus and the plane of radially inner side have an acute angle, the inner surface of top board and the horizontal plane of radially inner side have an acute angle, the inner surface of radial internal ring wall and horizontal vertical;
The inner surface of the radial inner surface of external annulus, the inner surface of top board and radial internal ring wall forms booster cavity, and fire hole is communicated with booster cavity.
The fire cover of a kind of gas burner of the utility model, owing to adopting such structure, during fire hole burning, form flame upwards, flame propagation speed, auxiliary air enters fast, and during burning, air is sufficient, and sufficient combustion, reaches the Energy Efficiency Ratio of national regulation.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1 and Figure 2, a kind of fire cover of gas burner, comprises top board 1, radial internal ring wall 2, radial external annulus 3 and outer ring interface 4, and radial external annulus 3 is provided with fire hole 5.The top surface distance being positioned at the top distance top board 1 of the fire hole end of radial outside of described fire hole 5 is 1-2 millimeter; Cylindrical or the truncated cone of the radial external annulus at the place of described fire hole 5 outlet side.
The radially inner side of described top board 1 is arc-shaped curved surface 11, radial outside is plane 12, and the distance being positioned at the radial edges of the plane 12 of the top distance top board 1 of the fire hole end of radial outside of described fire hole 5 is 1-2 millimeter
The axis of described fire hole 5 and the angle of horizontal plane are 30-45 degree.Namely the angle of the axis of fire hole 5 and the horizontal plane of below is 30-45 degree.
Described radial external annulus 3 is in truncated cone, and its coning angle is 9-30 degree.
The described inner surface of radial external annulus 3 and the plane of radially inner side have an acute angle, and the inner surface of top board 1 and the horizontal plane of radially inner side have an acute angle, the inner surface of radial internal ring wall 2 and horizontal vertical;
The inner surface of the radial inner surface of external annulus 3, the inner surface of top board 1 and radial internal ring wall 2 forms booster cavity, and fire hole 5 is communicated with booster cavity.
Above-described is only preferred embodiments of the present utility model.It should be pointed out that for the person of ordinary skill of the art, when not departing from the utility model principle, can also make some improvement and modification, this is also considered as protection domain of the present utility model.
