AI Technical Summary
It is difficult for existing gas burners to increase the number and total area of fire holes without increasing the outer diameter of the burner body, thereby increasing the power, and increasing the area of fire holes will lead to tempering and combustion instability.
The power adjustment plate and burner fire cover are designed with the power adjustment plate. The power adjustment plate is buckled on the burner body, and its outer diameter is larger than the burner body. The fire cover is connected to the power adjustment plate and has multiple fire holes. The material can be metal or ceramic, and the cross-section of the fire hole is concave. Through this design, the number and total area of fire holes are increased without changing the outer diameter of the burner body.
Without increasing the outer diameter of the burner body, the number of fire holes and the total area are increased, thereby increasing the power of the burner, avoiding the backfire phenomenon, and achieving a stable combustion effect.

Description
Technical field

[0002] With the continuous improvement of the scientific and technological level, the market share of cooking gas appliances is increasing day by day and is accepted by consumers. At present, the power of the burner of cooking gas appliances is determined by the total area of the flame holes, and the total area of the flame holes is determined by the number of flame holes, and the area of a single flame hole is determined by the type of gas. That is to say, there is a different fixed value for the area of a single flame hole for different types of gas. To increase the power of the burner, it is necessary to increase the total area of the flame holes, that is, only increase the number of single flame holes, thereby increasing the power.
[0003] However, it is very difficult for a burner body with a small power to increase the power by increasing the area of the flame holes. First of all, the outer diameter of the burner body is limited, and the number of flame holes is a fixed value. Secondly, the area of a single flame hole is limited, and increasing the flame holes will cause a flashback phenomenon, resulting in unstable combustion. If the number of flame holes is to be increased, it is necessary to increase the outer diameter of the burner body, which requires redesigning and manufacturing a large outer-edge burner body to increase the total area of the flame holes to increase the power of the burner.
[0004] In view of this, it is necessary to further improve the current structure. Content of the utility model

Specifically, the outer diameter of the side of the burner body 1 close to the power adjustment plate 2 is marked as D1 in the figure, and the outer diameter of the power adjustment plate 2 is marked as D2 in the figure. The outer diameter D2 of the power adjustment plate 2 is larger than the outer diameter D1 of the side of the burner body 1 close to the power adjustment plate 2. Buckling the power adjustment plate 2 on the burner body 1 can make the outer diameter D2 of the power adjustment plate 2 become the outer diameter of the burner body 1 without increasing the outer diameter D1 of the burner body 1.
[0034] The side of the power adjustment plate 2 away from the burner body 1 is abutted and connected with a burner cap 3, that is, the burner cap 3 is placed on the power adjustment plate 2. A plurality of fire holes 31 are arranged on the side of the burner cap 3 close to the power adjustment plate 2. Due to the limited outer edge diameter of the traditional burner body, but the number of fire holes is a fixed value. Secondly, the area of a single fire hole is limited, and enlarging the fire hole will cause flashback phenomenon, resulting in unstable combustion. If the number of fire holes is to be increased, the outer diameter of the burner body must be increased, which requires redesigning and manufacturing a large outer edge burner body.

Furthermore, without increasing the outer diameter D1 of the burner body 1, the outer diameter D2 of the power adjustment plate 2 becomes the outer diameter of the burner body 1, and the burner cap 3 can be placed on the power adjustment plate 2 in a matching manner, thereby increasing the number of flame holes 31 of the burner cap 3, increasing the total area of the flame holes 31, and improving the power of the burner.
[0041] Furthermore, the power adjustment plate 2 is in a circular ring shape, and the outer diameter of the power adjustment plate 2 is greater than the outer diameter of the conical surface portion 11.
[0042] In this embodiment, the power adjustment plate 2 is in a circular ring shape, and the inner edge of the circular ring-shaped power adjustment plate 2 is in contact with the inner edge of the burner body 1, so that the power adjustment plate 2 can be stably buckled on the burner body 1.
