Premixing type gas furnace end and gas cooker
By designing a premixed gas burner head where fuel and air or oxygen converge in the intake channel and are guided into the annular gas chamber along a spiral structure guide groove, the problem of poor premixing effect in existing systems is solved, resulting in better burner heating performance.

Abstract
The premixing type gas furnace end comprises a burner body, a fire cover and a gas inlet pipe, the burner body is provided with an annular gas cavity with an opening in the upper side, the fire cover is arranged on the upper side of the burner body, the gas inlet pipe is connected to the burner body and provided with a gas inlet channel communicated with the annular gas cavity, and the gas inlet channel is communicated with the annular gas cavity. The air inlet pipe is provided with a first pipe part and a second pipe part, the first pipe part is provided with a first channel used for inputting fuel, the second pipe part is provided with a second channel used for inputting air or oxygen, the first channel and the second channel are both communicated with the air inlet channel, and one of the first pipe part and the second pipe part is arranged at the end of the air inlet pipe. A guide groove of a spiral structure is formed in the bottom wall of the annular air cavity, and the end of the guide groove is in butt joint with the air inlet channel. According to the utility model, fuel and air (or oxygen) can be intersected and mixed in the air inlet channel and are spirally input into the annular air cavity along the guide groove, so that a better premixing effect is realized.
