In this scheme, the blocking part is used for sheltering from out the fire hole, and the blocking part corresponds the setting with the partition portion, makes the blocking part cover the partition portion at the first position through rotating barrier, shelters from out the fire hole at the second position.

Preferably, the top of fire lid body is equipped with annular recess, a plurality of go out the fire hole and be located the bottom of recess, the baffle is rotatably located in the recess.

In the scheme, the annular groove is used for placing the baffle; meanwhile, the baffle is limited, so that the baffle is prevented from being separated from the fire cover main body when in use.

Preferably, one side of the groove is provided with a first positioning groove and a second positioning groove, and the baffle is provided with a positioning part; in the first position, the positioning part is located in the first positioning groove, and in the second position, the positioning part is located in the second positioning groove.

In the scheme, the first positioning groove and the second positioning groove can be used for indicating the placing position of the baffle; in addition, place location portion in first constant head tank or second constant head tank, but the fixed baffle prevents that the baffle from taking place the rotation when using to influence the shape of flame.

Preferably, this internal biography fire groove and the air mixing chamber of having of fire lid, it is located to pass the fire groove the below of partition portion, be equipped with the division board between air mixing chamber and the biography fire groove, the fire hole is located the division board, the air mixing chamber with pass through to pass the fire groove the fire hole intercommunication.

In the scheme, the fire transfer groove is used for transferring fire, and flame passes through the fire transfer groove from the fire hole to reach the fire outlet hole; because the partition plate is arranged between the fire transfer groove and the gas mixing chamber, the fire transfer groove can protect the flame root from being interfered by peripheral air flow, so that the combustion is more stable; the fire transfer groove also has an energy gathering effect, and the partition plate prevents heat from diffusing to the periphery, so that the temperature of the fire hole root is higher, the fire transfer is more efficient, the combustion is more stable, and the efficiency is higher; moreover, the process of mixing primary gas and air is added, and stable and sufficient combustion is facilitated.

Preferably, the gas mixing chamber is arranged around the outer part of the fire transfer groove.

Preferably, the partition plate includes an upper inclined portion and a lower inclined portion connected to each other, the upper inclined portion is provided with a plurality of flame stabilizing holes, and the flame holes are disposed in the lower inclined portion.

In this aspect, the flame stabilizing holes are configured to interfere with the flame at the flame holes to stabilize the flame.

A cooker burner is characterized by comprising the fire cover.

On the basis of the common knowledge in the field, the above preferred conditions can be combined randomly to obtain the preferred embodiments of the invention.

The positive progress effects of the invention are as follows:

for the fire cover, the shielding condition of the fire outlet hole by the baffle is changed by switching the rotary baffle between the first position and the second position, so that the change of the flame shape is realized, and the requirements of users on flames with different shapes are met; in addition, when not using this fire lid for a long time, can locate the second position with the baffle for the fire hole below the fire hole is sheltered from, thereby protects the fire hole below the fire hole and not contaminated, prolongs the life-span of fire lid.
