[0037] In the following description, reference will be made to Figures 1 to 5 The detailed structures of the burner body 1 and the fire cover assembly of the burner structure with air supply function are described in detail.

[0038] like Figures 1 to 5As shown, in the embodiment, the burner body 1 is used as the main structure of the burner structure with air supply function, and is used to install the fire cover assembly described below. A through hole 101 is opened in the middle of the burner body 1. In this embodiment, the through hole 101 can be used as a channel for secondary air supply. Air can flow out through the through hole 101 via the air supply hole 204 described below, thereby realizing secondary air supply for flame combustion.

[0039] The fire cover assembly is arranged at the top of the burner body 1, and the fire cover assembly can be used for the exhaust of the mixed gas (combustion gas and primary air). Specifically, the fire cover assembly may include an inner fire cover 201 and an outer fire cover 202, wherein the inner fire cover 201 is arranged inside the outer fire cover 202, and the outer fire cover 202 is used to cover the outer ring mixing chamber 302 described below, and make the outer ring flame burn evenly, and the inner fire cover 201 is arranged in the inner ring mixing chamber 301 described below, so that the inner ring flame burns evenly.

The air supply hole 204 can be arranged on the side of the fire outlet 203, and air is supplied to the flame at the fire outlet 203. The air supply hole 204 is connected to the through hole 101, and the air flows out through the through hole 101 via the air supply hole 204. The burner structure with air supply function realizes secondary air supply during the combustion process by additionally arranging the air supply hole 204 on the fire cover assembly, thereby improving the combustion efficiency.

[0040] Preferably, if Figure 4 and Figure 5 As shown, in the embodiment, a connecting hole 209 is opened in the middle of the inner fire cover 201, and the connecting hole 209 is connected to the through hole 101. Since the inner fire cover 201 is separately covered on the upper part of the burner body 1, in order to ensure the fluidity of air, a connecting hole 209 connected to the through hole 101 is opened in the middle of the inner fire cover 201.

[0041] The connecting hole 209 can be connected with the air supply hole 204 through the air supply channel 205. Since the peripheral side of the inner fire cover 201 has a certain thickness, in order to improve the fluidity of the air, the peripheral side of the inner fire cover 201 is provided with an air supply channel 205 connected to the air supply hole 204. In addition, the air supply channel 205 can also be used to introduce the air used for secondary air supply to a designated position, for example, to introduce the air to the side of the fire outlet hole 203, so as to achieve precise air supply and improve combustion efficiency.

[0042] Preferably, the air supply flow channel 205 is arranged obliquely, and the obliquely arranged air supply flow channel 205 can increase the fluidity of air and achieve sufficient air supply.

The setting position of the first end of the air supply channel 205 is higher than the setting position of the second end of the air supply channel 205, so that the secondary supply air can be high-in and low-out, and the flow rate of the gas can be increased by using the dead weight of the air, thereby achieving sufficient air supply.

[0044] Preferably, if Figures 1 to 5 As shown, in an embodiment, the number of the air supply holes 204 can be multiple, and the multiple air supply holes 204 are evenly arranged on the outer peripheral side of the inner fire cover 201. The inner fire cover 201 can be formed into a nearly cylindrical structure. The multiple air supply holes 204 can be arranged along the outer peripheral surface of the inner fire cover 201 of the nearly cylindrical structure. The connecting line of the setting positions of the multiple air supply holes 204 can be formed into a circle, so that uniform air supply on the outer peripheral side of the inner fire cover 201 can be achieved.

[0045] Multiple air supply holes 204 are all arranged on the upper part of the fire outlet hole 203. The multiple air supply holes 204 located on the upper part can provide secondary air supply to the mixed gas ejected through the fire outlet hole 203, and can also provide air supply to the burning flame, so as to avoid the flame combustion due to insufficient secondary air supply, which will cause incomplete combustion, and easily cause excessive smoke, yellow flame and other phenomena.

[0046] Preferably, if Figures 1 to 5 As shown, in the embodiment, there are multiple fire holes 203, and multiple fire holes 203 are evenly arranged on the outer peripheral side of the inner fire cover 201. The inner fire cover 201 can be formed into a nearly cylindrical structure. Multiple fire holes 203 can be arranged along one side of the outer peripheral surface of the inner fire cover 201 of the nearly cylindrical structure. The fire holes 203 can include two fire holes 203 of different sizes, wherein the larger fire hole 203 is located at the lower part of the air supply hole 204, and the smaller fire hole 203 is located at the lower part of the larger fire hole 203. The fire holes 203 of different sizes can ensure the uniform combustion of the flame, and the combustion is divided by setting different angles and heights. The setting position of the air supply hole 204 is close to the larger fire hole 203, and the larger fire hole 203 can be given priority in air supply to ensure combustion efficiency.

[0047] An air supply hole 204 is disposed at the upper portion between every two adjacent ignition holes 203. Specifically, in the embodiment, an air supply hole 204 is disposed at the upper portion between every two adjacent ignition holes 203 of larger size. Such arrangement positions of the ignition holes 203 and the air supply holes 204 can realize one-to-one secondary air supply, further improve combustion efficiency, and ensure sufficient combustion.

[0048] Preferably, if Figures 1 to 5 As shown, in the embodiment, the burner structure with air supply function further includes a nozzle seat (not shown), the burner body 1 is arranged on the upper part of the nozzle seat, and the nozzle seat is penetrated by the through hole 101. Specifically, the nozzle seat can be used for the installation of the burner body 1, and connected to an external gas pipeline (not shown), the external gas can enter through the nozzle seat, and the gas and air are mixed once inside the nozzle seat, and then mixed into a mixed gas, and the mixed gas is transported to the burner body 1 for subsequent combustion.

[0049] Preferably, if Figures 1 to 5 As shown, in an embodiment, the nozzle seat may include an inner ring ejector tube (not shown), an outer ring ejector tube (not shown), an inner ring mixing chamber 301 and an outer ring mixing chamber 302. The inner ring ejector tube and the outer ring ejector tube may both be connected to an external gas pipeline and supply gas to the inner ring fire and the outer ring fire respectively. The inner ring ejector tube is connected to the inner ring mixing chamber 301, and the outer ring ejector tube is connected to the outer ring mixing chamber 302. After the gas enters the inner ring ejector tube and the outer ring ejector tube, it enters the inner ring mixing chamber 301 and the outer ring mixing chamber 302 and mixes with the primary air to form a mixed gas.

[0050] The outer fire cover 202 may include an outer ring gas outlet 207, the inner fire cover 201 includes an inner ring gas outlet 206, the inner ring ejector pipe is connected to the inner ring gas outlet 206 through the inner ring mixing chamber 301, and the outer ring ejector pipe is connected to the outer ring gas outlet 207 through the outer ring mixing chamber 302. The mixed gas entering the inner ring mixing chamber 301 and the outer ring mixing chamber 302 flows into the inner ring gas outlet 206 and the outer ring gas outlet 207, and finally ejects through the ignition holes 203 of the inner fire cover 201 and the outer fire cover 202, and then is ignited to achieve combustion.

[0051] Preferably, if Figure 2 As shown, in the embodiment, a pot rack 208 is further provided on the outer peripheral side of the fire cover assembly, and the pot rack 208 can be used to support the pot placed on the burner structure with the air supply function.

[0052] The working process of the burner structure with air supply function is as follows: the external gas pipeline is connected through the nozzle seat, and the gas enters the inner ring mixing chamber 301 and the outer ring mixing chamber 302 through the inner ring ejector tube and the outer ring ejector tube respectively, and is mixed with primary air in the inner ring mixing chamber 301 and the outer ring mixing chamber 302 to form a mixed gas, and the mixed gas enters the inner ring mixing chamber 301 and the outer ring mixing chamber 302, and is finally ejected through the fire holes 203 of the inner fire cover 201 and the outer fire cover 202. The flame after the gas ejected from the fire holes 203 of the inner fire cover 201 is burned serves as the main flame of the burner structure with air supply function, and the combustion volume is large, and secondary air supply can be achieved through the multiple air supply holes 204 arranged on the outer peripheral side of the inner fire cover 201. Figure 5 As shown, Figure 5 The middle arrow represents the flow direction of air. The air of the secondary air supply can enter the connecting hole 209 of the inner fire cover 201 through the through hole 101 opened in the nozzle seat and the burner body 1, and then be ejected through the air supply flow channel 205 to realize the secondary air supply.

[0053] The burner head structure with air supply function improves the structure of the burner head main body and the fire cover assembly, and utilizes the cooperation of the air supply hole and the through hole to realize secondary air supply to the main flame at the inner fire cover, so as to avoid the flame combustion due to insufficient secondary air supply, which will cause incomplete combustion, prone to excessive smoke and yellow flame, etc., thereby ensuring the efficiency and adequacy of the flame combustion.
