Description

Technical Field

[0001] The utility model relates to the technical field of burners, in particular to a boosted air intake structure of a burner. Background Art

[0002] At present, stoves are essential daily household appliances in modern kitchens. They usually include a stove top and a burner assembly arranged on the stove top, and the burner assembly is mainly composed of a base, a separation and concentration air disk and a combustion module. At the same time, a nozzle is arranged in the burner assembly, and the gas is subsequently guided to the combustion module through the nozzle, so that the burner combustion operation can be realized. For example, Chinese patent CN219867996U discloses a burner, including a base, an air distribution disk, at least one partition, a nozzle seat, and a plurality of nozzles. The air distribution disk is installed on the base, the nozzle seat is installed on the base, the nozzles are arranged on the nozzle seat at intervals, and a partition is provided between two adjacent nozzles. The partition divides the area between the air distribution disk and the nozzle seat into a plurality of cavities, and the nozzles and the cavities are arranged one by one. The nozzle seat has an air supply port, and the air supply port is connected to some of the cavities.

[0003] When the nozzle in the above-mentioned burner assembly is performing the jet operation, the air is only injected through the negative pressure formed by the nozzle when the gas is ejected, thereby transporting the air and gas into the burner assembly. However, only using this jet method alone cannot ensure that the gas and air delivered into the burner assembly are fully mixed, which will cause incomplete combustion of the burner assembly when it is working, and will reduce the overall combustion efficiency of the burner assembly.

[0010] The beneficial effect of the utility model is that when the air supply operation is performed, the air outlet end of the air guide member is matched with the second air inlet, so that external air can be directly sprayed into the second air inlet through the air outlet end of the air guide member, and the second air inlet is subsequently matched with the first air inlet, so that the second air inlet is connected to the first air inlet, so that the gas at the second air inlet can be sprayed into the first air inlet, and finally the external air can be directly sprayed into the burner assembly through the first air inlet, and then the negative pressure generated by the nozzle when the gas is sprayed can be accelerated to send the air entering from the first air inlet into the burner assembly, so that the air sprayed into the burner assembly can be quickly mixed with the gas, and the cooperation of the two can increase the intake pressure of the burner assembly, thereby ensuring that the air can be quickly delivered to the burner assembly, avoiding the situation of insufficient combustion when the burner assembly is working, and improving the overall combustion efficiency of the burner assembly.
