Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of stove burners, in particular to a blast type premixing disk. Background Art
[0002] Household burners usually use an ejector tube to inject gas and air into the burner body for premixing before output. This premixing process mainly depends on the performance of the ejector tube. The longer the ejector tube is, the better the premixing effect is. However, based on the volume of household burners, the ejector tube is usually short, which makes the gas and air not fully premixed in the burner body, making it easy for yellow flames to appear when the gas is output and burned. The main reason for this is that the air cannot be actively blown into the ejector tube, so the ejector tube does not inhale enough air.
[0003] Therefore, there is a need for a premixing disk that can actively blow air into the combustor. Utility Model Content

[0006] The beneficial effect of the utility model is that the blower is used to blow air into the blast chamber, so that air continuously enters the premixing chamber, thereby causing the air to be continuously blown into the gas inlet at the bottom of the burner. Compared with traditional burners, this active air supplementation method can make the air and gas more fully mixed in the burner, reduce the generation of yellow flames, burn more completely, and have higher combustion efficiency.
