It should be understood that a gas range is a device for generating a flame by burning fuel gas, which is introduced into the gas range and mixed with air to form a mixed gas, which is ignited to form a flame, and thus, the gas range needs to be connected to a gas line to input the fuel gas to the gas range, and an air port for allowing air to enter is also provided so that the air can be mixed with the fuel gas to form a mixed gas. Therefore, the burner assembly of the present application may further comprise a distributor, one end of the injection pipe 200 may be connected to the gas pipeline, and the other end of the injection pipe 200 may be connected to the distributor.

Specifically, a gas path is arranged in the distributor, and mixed gas formed after fuel gas and air are mixed can enter the distributor and is distributed in the gas path of the distributor, so that the mixed gas in the gas path of the distributor is ignited to form flame. Of course, the fuel gas can be directly injected into the distributor, so that the fuel gas is mixed with air in the process of distributing the fuel gas in the gas path of the distributor, and the aim of mixing the fuel gas with the air can be achieved. The injection pipe 200 is a gas supply mechanism of the gas stove, and the fuel gas can be input into the injection pipe 200 through the gas pipeline. After entering the injector tube 200, the fuel gas finally enters the distributor. The ejector tube 200 can be provided with a primary air port, air outside the gas stove can enter the ejector tube 200 through the primary air port, so that fuel gas and air in the ejector tube 200 are mixed to form mixed gas, the air in the mixed gas enables the fuel gas to be in an environment with rich oxygen content, and after the mixed gas is input into the distributor, the mixed gas in the distributor is ignited through an ignition mechanism of the gas stove to form flame.

Wherein, brace table 100 is the basic component of the furnace end subassembly of this application, and brace table 100 can provide the installation basis for other at least partial parts of the furnace end subassembly of this application, and the ejector tube 200 of this application sets up in brace table 100, and brace table 100 can play the effect of fixed stay ejector tube 200 to make ejector tube 200 fixable.

The number of the supporting legs 300 is two, the two supporting legs 300 can be connected with the supporting table 100, specifically, the two supporting legs 300 are connected with one side of the supporting table 100, which is opposite to the distributor, namely, one side of the bottom of the supporting table 100, and one side of the two supporting legs 300, which is opposite to the supporting table 100, can be connected with the bottom shell of the gas stove, so that the whole burner assembly can be fixed on the bottom shell. The connection of at least two legs 300 to the housing may allow more points of support of the support table 100 to be supported, thereby allowing the structure of the support table 100 to be more stable while also allowing the table top of the support table 100 to maintain a horizontal posture.

It should be understood that since the number of the legs 300 is at least two, it is necessary to make both the legs 300 correspond to the fitting structure of the bottom chassis when the legs 300 are fitted to the bottom chassis, so that the relative positional relationship of the two legs 300 needs to be maintained stable. Therefore, the positioning member 400 of the present application can be connected with the two legs 300, and the positioning member 400 has a stable structure, so that the positioning member 400 can fix the two legs 300, so that the relative positional relationship of the two legs 300 is kept stable, and thus the relative positional relationship can be kept stable even after the legs 300 are impacted by an external force. In addition, in the case that the support leg 300 is connected to the bottom shell to receive force, the positioning member 400 can also share the force applied to the support leg 300, so as to reduce the risk of deformation caused by excessive force applied to the support leg 300.
