[0046] The present application provides a gas stove, in combination with Figure 1 and Figure 2 As shown, in some embodiments, the gas stove includes a burner 1000 and a two-ring valve body 2000. The burner 1000 is provided with an outer-ring flame hole 1101, a middle-ring flame hole 1102, and an inner-ring flame hole 1103. The two-ring valve body 2000 is provided with a first gas outlet passage 2100 and a second gas outlet passage 2200. Among them, one of the outer-ring flame hole 1101, the middle-ring flame hole 1102, and the inner-ring flame hole 1103 is in communication with the first gas outlet passage 2100, and the first gas outlet passage 2100 supplies gas to the aforementioned one, so that the gas is ejected from the aforementioned one. The remaining two of the outer-ring flame hole 1101, the middle-ring flame hole 1102, and the inner-ring flame hole 1103 are in communication with the second gas outlet passage 2200, and the second gas outlet passage 2200 supplies gas to the aforementioned remaining two, so that the gas is ejected from the aforementioned remaining two.

[0047] Specifically, the burner 1000 is provided with an outer ring flame hole 1101, a middle ring flame hole 1102 and an inner ring flame hole 1103. It can be understood that the so-called outer ring flame hole 1101, middle ring flame hole 1102 and inner ring flame hole 1103 mean that the outer ring flame hole 1101 is farther from the center of the burner 1000 than the middle ring flame hole 1102 and the inner ring flame hole 1103, the inner ring flame hole 1103 is closer to the center of the burner 1000 than the outer ring flame hole 1101 and the middle ring flame hole 1102, and the middle ring flame hole 1102 is arranged between the outer ring flame hole 1101 and the inner ring flame hole 1103. That is to say, when observing along the top-down direction, the outer ring flame hole 1101 is more outward, and the inner ring flame hole 1103 is more inward. In this way, the inner ring flame hole 1103, the middle ring flame hole 1102 and the outer ring flame hole 1101 are arranged in sequence in the direction away from the center of the burner 1000, so that the burner 1000 can form a three-ring flame. The center of the burner 1000 can be understood as the center of the flame outlet range. In this embodiment, the orientation takes the installation of the gas stove in the use environment as an example. The side of the gas stove close to the ground is the bottom, and the side away from the ground is the top. It can be understood that the structural forms of the outer ring flame hole 1101, the middle ring flame hole 1102 and the inner ring flame hole 1103 are various. They can be in the form of a ring slot, or a plurality of (at least two) independent hole structures are arranged in a ring shape.

[0048] For example, in combination with Figure 7 、 Figure 8 、 Figure 9 and Figure 10As shown in the figure, the burner 1000 includes a burner head 1200 and a burner cap 1100. The burner head 1200 is provided with a first annular wall 1210, a second annular wall 1220, a third annular wall 1230, and a fourth annular wall 1240. The fourth annular wall 1240 surrounds the third annular wall 1230, the third annular wall 1230 surrounds the second annular wall 1220, the second annular wall 1220 surrounds the first annular wall 1210, and the first annular wall 1210 is provided with a first cavity 1250. A second cavity 1260 is defined between the second annular wall 1220 and the third annular wall 1230, and a third cavity 1270 is defined between the third annular wall 1230 and the fourth annular wall 1240. The burner cap 1100 is placed on the burner head 1200 and covers the first cavity 1250, the second cavity 1260, and the third cavity 1270. The burner cap 1100 is provided with outer-ring flame holes 1101, middle-ring flame holes 1102, and inner-ring flame holes 1103. The outer-ring flame holes 1101 communicate with the third cavity 1270, the middle-ring flame holes 1102 communicate with the second cavity 1260, and the inner-ring flame holes 1103 communicate with the first cavity 1250. Gas is introduced into the first cavity 1250 and ejected from the inner-ring flame holes 1103 and is ignited to form a flame. Gas is introduced into the second cavity 1260 and ejected from the middle-ring flame holes 1102 and is ignited to form a flame. Gas is introduced into the third cavity 1270 and ejected from the outer-ring flame holes 1101 and is ignited to form a flame. Thus, a three-ring flame is formed. In this embodiment, the gas is a mixture of fuel gas and air.

[0049] The gas supply to the burner 1000 needs to be carried out through a gas valve. In the related art, in order to supply gas to the outer-ring flame holes 1101, the middle-ring flame holes 1102, and the inner-ring flame holes 1103, a three-ring valve body (the three-ring valve body is a gas valve) needs to be used. The so-called three-ring valve body has three gas outlet channels. For example, the three-ring valve body includes a valve seat and a valve core. The valve core is rotatably arranged in the valve seat. The valve core is provided with a first gas passage hole, a second gas passage hole, and a third gas passage hole. The valve seat is provided with a first gas outlet hole, a second gas outlet hole, and a third gas outlet hole. The first gas outlet hole, the second gas outlet hole, and the third gas outlet hole communicate with the three gas outlet channels in one-to-one correspondence. The fuel gas of bottled liquefied petroleum gas or pipeline natural gas is transported into the valve core (the valve core is a hollow structure), then passes through the first gas passage hole, the second gas passage hole, and / or the third gas passage hole, and flows out to the corresponding gas outlet channels through the first gas outlet hole, the second gas outlet hole, and / or the third gas outlet hole. By changing the overlapping area of the first gas passage hole and the first gas outlet hole, the overlapping area of the second gas passage hole and the second gas outlet hole, and the overlapping area of the third gas passage hole and the third gas outlet hole, the gas flow rate can be adjusted. This type of three-ring valve body structure is relatively complex and has a high cost. The two-ring valve body 2000 (the two-ring valve body 2000 is a gas valve) is simpler in structure and lower in cost than the three-ring valve body, and there are more optional types. Therefore, in this embodiment, the two-ring valve body 2000 is used to supply gas to the outer-ring flame holes 1101, the middle-ring flame holes 1102, and the inner-ring flame holes 1103.

[0050] The two-ring valve body 2000 has two gas outlet channels, namely the first gas outlet channel 2100 and the second gas outlet channel 2200. Similar to the three-ring valve body, the two-ring valve body 2000 also includes a valve seat and a valve core. The valve core is rotatably arranged in the valve seat. Different from the three-ring valve body, the valve core is provided with a first air passage hole and a second air passage hole, and the valve seat is provided with a first air outlet hole and a second air outlet hole. The first air outlet hole is correspondingly communicated with the first gas outlet channel 2100, and the second air outlet hole is correspondingly communicated with the second gas outlet channel 2200. The gas of canned liquefied gas or pipeline natural gas is transported into the valve core (the valve core is a hollow structure), then passes through the first air passage hole and / or the second air passage hole, and flows to the corresponding first gas outlet channel 2100 and second gas outlet channel 2200 through the first air outlet hole and / or the second air outlet hole. By changing the overlapping area of the first air passage hole and the first air outlet hole, and the overlapping area of the second air passage hole and the second air outlet hole, the gas flow rate can be adjusted.

[0051] One of the outer ring flame holes 1101, the middle ring flame holes 1102 and the inner ring flame holes 1103 is communicated with the first gas outlet channel 2100, and the gas output from the first gas outlet channel 2100 is ejected from one of the foregoing. The remaining two of the outer ring flame holes 1101, the middle ring flame holes 1102 and the inner ring flame holes 1103 are communicated with the second gas outlet channel 2200, and the gas output from the second gas outlet channel 2200 is ejected from the remaining two of the foregoing. In this way, the control of the three-ring flame can be realized through the two-ring valve body 2000.

[0052] It can be understood that one of the outer ring flame holes 1101, the middle ring flame holes 1102 and the inner ring flame holes 1103 is communicated with the first gas outlet channel 2100, and the remaining two of the outer ring flame holes 1101, the middle ring flame holes 1102 and the inner ring flame holes 1103 are communicated with the second gas outlet channel 2200. There are various combinations of one of the foregoing and the remaining two of the foregoing. When one of the foregoing is the outer ring flame hole 1101, the remaining two are the middle ring flame holes 1102 and the inner ring flame holes 1103. When one of the foregoing is the middle ring flame hole 1102, the remaining two are the outer ring flame holes 1101 and the inner ring flame holes 1103. When one of the foregoing is the inner ring flame hole 1103, the remaining two are the outer ring flame holes 1101 and the middle ring flame holes 1102.

[0053] When one of the foregoing is the outer ring flame holes 1101 and the remaining two are the middle ring flame holes 1102 and the inner ring flame holes 1103, the outer ring flame holes 1101 communicate with the first gas outlet channel 2100, and the middle ring flame holes 1102 and the inner ring flame holes 1103 respectively communicate with the second gas outlet channel 2200. The gas output by the two-ring valve body 2000 through the first gas outlet channel 2100 finally jets out from the outer ring flame holes 1101, and the gas output by the second gas outlet channel 2200 finally jets out from the middle ring flame holes 1102 and the inner ring flame holes 1103.

[0054] When one of the foregoing is the middle ring flame holes 1102 and the remaining two are the outer ring flame holes 1101 and the inner ring flame holes 1103, the middle ring flame holes 1102 communicate with the first gas outlet channel 2100, and the outer ring flame holes 1101 and the inner ring flame holes 1103 respectively communicate with the second gas outlet channel 2200. The gas output by the two-ring valve body 2000 through the first gas outlet channel 2100 finally jets out from the middle ring flame holes 1102, and the gas output by the second gas outlet channel 2200 finally jets out from the outer ring flame holes 1101 and the inner ring flame holes 1103.

[0055] When one of the foregoing is the inner ring flame holes 1103 and the remaining two are the outer ring flame holes 1101 and the middle ring flame holes 1102, the inner ring flame holes 1103 communicate with the first gas outlet channel 2100, and the outer ring flame holes 1101 and the middle ring flame holes 1102 respectively communicate with the second gas outlet channel 2200. The gas output by the two-ring valve body 2000 through the first gas outlet channel 2100 finally jets out from the inner ring flame holes 1103, and the gas output by the second gas outlet channel 2200 finally jets out from the outer ring flame holes 1101 and the middle ring flame holes 1102.

[0056] It can be understood that since the remaining two of the foregoing communicate with the second gas outlet channel 2200, the two-ring valve body 2000 can realize the same large and small adjustment of the firepower of the remaining two of the foregoing. For example, if the remaining two of the foregoing are the outer ring flame holes 1101 and the middle ring flame holes 1102, then when the two-ring valve body 2000 adjusts, it can make the firepower of the outer ring holes and the middle ring flame holes 1102 increase or decrease simultaneously.

[0057] Thus, by making one of the outer ring flame holes 1101, the middle ring flame holes 1102 and the inner ring flame holes 1103 communicate with the first gas outlet channel 2100, and the remaining two of the outer ring flame holes 1101, the middle ring flame holes 1102 and the inner ring flame holes 1103 communicate with the second gas outlet channel 2200, the two-ring valve body 2000 can also realize the adjustment of the three-ring flame. Compared with the three-ring valve body, the two-ring valve body 2000 can also reduce the structural complexity and cost, and there are more choices for the type of the two-ring valve body 2000.

[0058] Combined Figure 1 and Figure 2As shown, in some embodiments, the gas stove further includes a first gas pipeline 3100, and the two-ring valve body 2000 supplies gas to one of the aforementioned components through the first gas pipeline 3100. Specifically, one end of the first gas pipeline 3100 is connected to the first gas outlet channel 2100, and the other end of the first gas pipeline 3100 is connected to one of the aforementioned components. Thus, the gas output from the first gas outlet channel 2100 enters the first gas pipeline 3100, is transmitted along the first gas pipeline 3100 to the burner 1000, and finally is ejected from one of the aforementioned components.

[0059] For example, taking one of the aforementioned components as the inner-ring flame holes 1103 for illustration, the first gas outlet channel 2100 is provided with a first gas outlet end 2110. One end of the first gas pipeline 3100 is inserted into the first gas outlet end 2110 for connection. The other end of the first gas pipeline 3100 is connected to the first cavity 1250. The two-ring valve body 2000 controls the gas to flow out of the first gas outlet channel 2100. The gas enters the first gas pipeline 3100 from the first gas outlet end 2110, then enters the first cavity 1250, and finally is ejected from the inner-ring flame holes 1103.

[0060] Generally speaking, the first gas pipeline 3100 needs to be connected to one of the aforementioned components through a first ejector pipe 1310 to supply gas. Combining Figure 1 As shown, taking one of the aforementioned components as the inner-ring flame holes 1103 for illustration, the inner-ring flame holes 1103 are connected to the first cavity 1250. The first cavity 1250 is connected to the first ejector pipe 1310. The other end of the first gas pipeline 3100 is provided with a nozzle, and the nozzle is aligned with the intake end of the first ejector pipe 1310. The gas is sprayed into the first ejector pipe 1310 through the nozzle, then enters the first cavity 1250, and finally is ejected from the inner-ring flame holes 1103.

[0061] Combining Figure 1 and Figure 2 As shown, in some embodiments, the gas stove further includes a second gas pipeline 3200 and a third gas pipeline 3300. The second gas pipeline 3200 is used to supply gas to one of the remaining two of the aforementioned components, and the third gas pipeline 3300 is used to supply gas to the other of the remaining two of the aforementioned components.

[0062] Specifically, one end of the second gas pipeline 3200 is connected to the second gas outlet passage 2200, and the other end of the second gas pipeline 3200 is connected to one of the remaining two aforesaid ones. In this way, a part of the gas output from the second gas outlet passage 2200 enters the second gas pipeline 3200, is transmitted along the second gas pipeline 3200 to the burner 1000, and is finally ejected from one of the remaining two aforesaid ones. One end of the third gas pipeline 3300 is connected to the second gas outlet passage 2200, and the other end of the third gas pipeline 3300 is connected to the other of the remaining two aforesaid ones. In this way, a part of the gas output from the second gas outlet passage 2200 enters the third gas pipeline 3300, is transmitted along the third gas pipeline 3300 to the burner 1000, and is finally ejected from the other of the remaining two aforesaid ones.

[0063] It can be understood that when the remaining two aforesaid ones are the outer ring flame holes 1101 and the middle ring flame holes 1102, one of them is the outer ring flame hole 1101 and the other is the middle ring flame hole 1102; when the remaining two aforesaid ones are the outer ring flame holes 1101 and the inner ring flame holes 1103, one of them is the outer ring flame hole 1101 and the other is the inner ring flame hole 1103; when the remaining two aforesaid ones are the middle ring flame holes 1102 and the inner ring flame holes 1103, one of them is the middle ring flame hole 1102 and the other is the inner ring flame hole 1103.

[0064] For example, taking the remaining two aforesaid ones as the outer ring flame holes 1101 and the middle ring flame holes 1102 as an example for illustration, the second gas outlet passage 2200 is provided with a second gas outlet end 2210 and a third gas outlet end 2220. One end of the second gas pipeline 3200 is inserted into the second gas outlet end 2210 for connection, and the other end of the second gas pipeline 3200 is connected to the second cavity 1260. The two-ring valve body 2000 controls the gas to flow out of the second gas outlet passage 2200. The gas enters the second gas pipeline 3200 from the second gas outlet end 2210, then enters the second cavity 1260, and is finally ejected from the middle ring flame hole 1102. One end of the third gas pipeline 3300 is inserted into the third gas outlet end 2220 for connection, and the other end of the third gas pipeline 3300 is connected to the third cavity 1270. The two-ring valve body 2000 controls the gas to flow out of the second gas outlet passage 2200. The gas enters the third gas pipeline 3300 from the third gas outlet end 2220, then enters the third cavity 1270, and is finally ejected from the outer ring flame hole 1101.

[0065] Generally speaking, the second gas pipeline 3200 needs to be connected to one of the remaining two aforesaid ones through the second ejector pipe 1320 to supply gas, and the third gas pipeline 3300 needs to be connected to the other of the remaining two aforesaid ones through the third ejector pipe 1330 to supply gas. Combined with Figure 1As shown in the figure, taking one of the remaining two as the middle ring flame holes 1102 and the other as the outer ring flame holes 1101 as an example for illustration, the middle ring flame holes 1102 communicate with the second cavity 1260, the second cavity 1260 communicates with the second ejector tube 1320, a nozzle is provided at the other end of the second gas supply pipe 3200, the nozzle is aligned with the intake end of the second ejector tube 1320, the gas is sprayed into the second ejector tube 1320 through the nozzle, then enters the second cavity 1260, and finally is ejected from the middle ring flame holes 1102. The outer ring flame holes 1101 communicate with the third cavity 1270, the third cavity 1270 communicates with the third ejector tube 1330, a nozzle is provided at the other end of the third gas supply pipe 3300, the nozzle is aligned with the intake end of the third ejector tube 1330, the gas is sprayed into the third ejector tube 1330 through the nozzle, then enters the third cavity 1270, and finally is ejected from the outer ring flame holes 1101.

[0066] Combined with Figure 3 and Figure 4 As shown in the figure, in some embodiments, the gas stove further includes a fourth gas supply pipe 3400, a fifth gas supply pipe 3500, a sixth gas supply pipe 3600 and a tee joint 3700, and the remaining two are supplied with gas through the cooperation of the fourth gas supply pipe 3400, the fifth gas supply pipe 3500, the fifth gas supply pipe 3500 and the tee joint 3700.

[0067] Specifically, the tee joint 3700 has a first end, a second end and a third end that communicate with each other. One end of the fourth gas supply pipe 3400 communicates with the second gas outlet channel 2200, the other end of the fourth gas supply pipe 3400 communicates with the first end, one end of the fifth gas supply pipe 3500 communicates with the second end of the tee joint 3700, the other end of the fifth gas supply pipe 3500 communicates with one of the remaining two, one end of the sixth gas supply pipe 3600 communicates with the third end of the tee joint 3700, and the other end of the sixth gas supply pipe 3600 communicates with the other of the remaining two. In this way, the gas output from the second gas outlet channel 2200 enters the fourth gas supply pipe 3400, and after flowing through the tee joint 3700, a part of the gas flows to the fifth gas supply pipe 3500 and then enters the burner 1000 and is finally ejected from one of the remaining two, and a part of the gas flows to the sixth gas supply pipe 3600 and then enters the burner 1000 and is finally ejected from the other of the remaining two.

[0068] For example, taking the remaining two, namely the outer ring flame holes 1101 and the middle ring flame holes 1102, as an example for illustration, the second air outlet channel 2200 is provided with a fourth air outlet end 2230. One end of the fourth gas pipeline 3400 is inserted into the fourth air outlet end 2230 for connection. The other end of the fourth gas pipeline 3400 is inserted into the first end of the tee joint 3700 for connection. One end of the fifth gas pipeline 3500 is inserted into the second end of the tee joint 3700 for connection. The other end of the fifth gas pipeline 3500 is connected to the second cavity 1260. One end of the sixth gas pipeline 3600 is inserted into the third end of the tee joint 3700 for connection. The other end of the sixth gas pipeline 3600 is connected to the third cavity 1270. The second ring valve body 2000 controls the gas to flow out from the second air outlet channel 2200. The gas enters the fourth gas pipeline 3400 from the fourth air outlet end 2230 and flows through the tee joint 3700. After flowing through the tee joint 3700, a part of the gas flows to the fifth gas pipeline 3500 and then enters the second cavity 1260 and finally sprays out from the middle ring flame holes 1102, and a part of the gas flows to the sixth gas pipeline 3600 and then enters the third cavity 1270 and finally sprays out from the outer ring flame holes 1101.

[0069] Generally speaking, the fifth gas pipeline 3500 needs to be connected to one of the remaining two through the second ejector pipe 1320 to supply gas, and the sixth gas pipeline 3600 needs to be connected to the other of the remaining two through the third ejector pipe 1330 to supply gas. Combining Figure 3 As shown, taking one of the remaining two as the middle ring flame holes 1102 and the other as the outer ring flame holes 1101 for illustration, the middle ring flame holes 1102 are connected to the second cavity 1260. The second cavity 1260 is connected to the second ejector pipe 1320. The other end of the fifth gas pipeline 3500 is provided with a nozzle, and the nozzle is aligned with the air inlet end of the second ejector pipe 1320. The gas is sprayed into the second ejector pipe 1320 through the nozzle, then enters the second cavity 1260, and finally sprays out from the middle ring flame holes 1102. The outer ring flame holes 1101 are connected to the third cavity 1270. The third cavity 1270 is connected to the third ejector pipe 1330. The other end of the sixth gas pipeline 3600 is provided with a nozzle, and the nozzle is aligned with the air inlet end of the third ejector pipe 1330. The gas is sprayed into the third ejector pipe 1330 through the nozzle, then enters the third cavity 1270, and finally sprays out from the outer ring flame holes 1101.

[0070] Combining Figures 1 to 10As shown, in some embodiments, one of the foregoing is the inner ring flame holes 1103, and the remaining two are the outer ring flame holes 1101 and the middle ring flame holes 1102. That is, the first air outlet channel 2100 communicates with the inner ring flame holes 1103 to supply gas, so that the gas can be ejected from the inner ring flame holes 1103. The second air outlet channel 2200 communicates with the outer ring flame holes 1101 and the middle ring flame holes 1102, so that the gas can be ejected from the outer ring flame holes 1101 and the middle ring flame holes 1102. As can be seen from the above, the outer ring flame holes 1101 are more outward relative to the middle ring flame holes 1102 and the inner ring flame holes 1103, and the inner ring flame holes 1103 are more inward relative to the outer ring flame holes 1101 and the middle ring flame holes 1102. In this embodiment, the two-ring valve body 2000 controls the gas supply to the outer ring flame holes 1101 and the middle ring flame holes 1102 through the second air outlet channel 2200, and controls the gas supply to the inner ring flame holes 1103 through the first air outlet channel 2100. Thus, when the two-ring valve body 2000 controls the second air outlet channel 2200 to close and interrupts the gas supply to the outer ring flame holes 1101 and the middle ring flame holes 1102, the gas supply to the first air outlet channel 2100 can still be controlled, so that the inner ring flame holes 1103 generate flames, thus realizing the minimum fire state of the burner 1000.

[0071] In some embodiments, the inner ring flame holes 1103 are also suitable for ejecting entrained air, that is, the inner ring flame holes 1103 can eject gas and entrained air. The middle ring flame holes 1102 are also suitable for ejecting blast air, that is, the middle ring flame holes 1102 can eject gas and blast air. The outer ring flame holes 1101 are also suitable for ejecting entrained air, that is, the outer ring flame holes 1101 can eject gas and entrained air.

[0072] Compared with the entrained air, the blast air can provide more oxygen, so that the gas ejected from the middle ring flame holes 1102 is in a state of rich-oxygen combustion, thus enabling the full combustion of the gas ejected from the middle ring flame holes 1102 (the flame generated by the middle ring flame holes 1102 can still entrain the secondary air in the surrounding environment to participate in combustion). When the entrained air ejected from the outer ring flame holes 1101 is not sufficient to support the combustion of the gas ejected from the outer ring flame holes 1101, secondary air needs to be supplemented. Since the blast air is ejected from the middle ring flame holes 1102, the blast air ejected from the middle ring flame holes 1102 can provide enough oxygen, so that in addition to participating in the combustion of the gas ejected from the middle ring flame holes 1102, the blast air ejected from the middle ring flame holes 1102 can also provide excess oxygen to supplement the gas ejected from the outer ring flame holes 1101, assisting the combustion of the gas ejected from the outer ring flame holes 1101. Compared with supplementing secondary air from the surrounding environment by entrainment, the excess oxygen provided by the blast air ejected from the middle ring flame holes 1102 is more actively supplemented into the gas ejected from the outer ring flame holes 1101. By such a setting, the gas ejected from the outer ring flame holes 1101 is fully combusted (in this case, the flame generated by the outer ring flame holes 1101 can still entrain the secondary air in the surrounding environment to participate in combustion).

[0073] When the entrained air ejected from the inner ring flame holes 1103 is not sufficient to support the combustion of the gas ejected from the inner ring flame holes 1103, secondary air needs to be supplemented. Since the blast air is ejected from the middle ring flame holes 1102, the blast air ejected from the middle ring flame holes 1102 can provide enough oxygen, so that in addition to participating in the combustion of the gas ejected from the middle ring flame holes 1102, the blast air ejected from the middle ring flame holes 1102 can also provide excess oxygen to supplement the gas ejected from the inner ring flame holes 1103, assisting the combustion of the gas ejected from the inner ring flame holes 1103. Compared with supplementing secondary air from the surrounding environment by entrainment, the excess oxygen provided by the blast air ejected from the middle ring flame holes 1102 is more actively supplemented into the gas ejected from the inner ring flame holes 1103. By such a setting, the gas ejected from the inner ring flame holes 1103 is fully combusted (in this case, the flame generated by the inner ring flame holes 1103 can still entrain the secondary air in the surrounding environment to participate in combustion).

[0074] Combined with Figures 1 to 4As shown, in some embodiments, the burner 1000 receives the gas supply from the first gas outlet passage 2100 through the first ejector tube 1310 and ejects air. Specifically, the gas supply can come from bottled liquefied gas or pipeline natural gas. The gas is transported to the two-ring valve body 2000, and the two-ring valve body 2000 controls the gas to be ejected from the first gas outlet passage 2100. The gas discharged from the first gas outlet passage 2100 jets the gas towards the inlet end of the first ejector tube 1310 (for example, the end of the first gas pipeline 3100 in the previous text is provided with a nozzle and is aligned with the inlet end of the first ejector tube 1310). During the process of the gas jetting into the first ejector tube 1310, a negative pressure is formed in the surrounding environment, so that the air in the surrounding environment is synchronously ejected into the first ejector tube 1310 along with the jetting of the gas (this part of the air entering the first ejector tube 1310 through the ejector action is called the ejector air, and the ejector air is the primary air). The gas and the ejector air then enter the first cavity 1250 and are then ejected from the inner ring flame holes 1103.

[0075] The burner 1000 receives the gas supply from the second gas outlet passage 2200 through the third ejector tube 1330 and ejects air. Specifically, the gas supply can come from bottled liquefied gas or pipeline natural gas. The gas is transported to the two-ring valve body 2000, and the two-ring valve body 2000 controls the gas to be ejected from the second gas outlet passage 2200. The gas discharged from the second gas outlet passage 2200 jets the gas towards the inlet end of the third ejector tube 1330 (for example, the end of the third gas pipeline 3300 in the previous text is provided with a nozzle and is aligned with the inlet end of the third ejector tube 1330, and the end of the sixth gas pipeline 3600 is provided with a nozzle and is aligned with the inlet end of the third ejector tube 1330). During the process of the gas jetting into the third ejector tube 1330, a negative pressure is formed in the surrounding environment, so that the air in the surrounding environment is synchronously ejected into the third ejector tube 1330 along with the jetting of the gas (this part of the air entering the third ejector tube 1330 through the ejector action is called the ejector air, and the ejector air is the primary air). The gas and the ejector air then enter the third cavity 1270 and are then ejected from the outer ring flame holes 1101.

[0076] The burner 1000 receives the gas supply from the second gas outlet passage 2200 through the second ejector tube 1320 and receives the blast air. Specifically, the gas supply can come from bottled liquefied gas or pipeline natural gas. The gas is transported to the second-ring valve body 2000, and the second-ring valve body 2000 controls the gas to be ejected from the second gas outlet passage 2200. The gas discharged from the second gas outlet passage 2200 jets the gas towards the intake end of the second ejector tube 1320 (for example, the end of the second gas pipeline 3200 in the previous text is provided with a nozzle and is aligned with the intake end of the second ejector tube 1320, and the end of the fifth gas pipeline 3500 is provided with a nozzle and is aligned with the intake end of the second ejector tube 1320). During the process of the gas jetting into the second ejector tube 1320, blast air is provided. The blast air is generated by a fluid machine, for example, the blast air is provided by forced air blowing of a blower. The blast air enters the second ejector tube 1320 through the intake end of the second ejector tube 1320. The blast air and the gas enter the second cavity 1260 (the blast air is primary air), and then are ejected from the middle-ring flame holes 1102.

[0077] In some embodiments of the present application, when the second-ring valve body 2000 interrupts the gas supply to the outer-ring flame holes 1101 and the middle-ring flame holes 1102 and maintains the gas supply to the inner-ring flame holes 1103, at this time, the blower is still in the working state to provide the blast air. When adjusting the second-ring body to interrupt the gas supply to the outer-ring flame holes 1101 and the middle-ring flame holes 1102, the gas supply to the inner-ring flame holes 1103 can still be maintained (for example, the firepower adjustment changes from large to small). At this time, it is controlled that the blower is still in the working state. In this way, the air (blast air) forcibly transported by the blower is provided to the middle-ring flame holes 1102 and ejected from the middle-ring flame holes 1102. The ejected blast air can be supplemented into the gas ejected from the inner-ring flame holes 1103 to participate in combustion, ensuring that the gas ejected from the inner-ring flame holes 1103 can also burn sufficiently at the minimum fire.

[0078] In some embodiments, the burner cap 1100 includes an inner-ring burner cap 1110. The inner-ring burner cap 1110 is provided with inner-ring flame holes 1103. The inner-ring burner cap 1110 is a porous ceramic plate, so that the inner-ring burner cap 1110 forms infrared combustion (constitutes an infrared combustion burner cap), which is beneficial to achieving minimum-fire combustion. And the heat intensity of its flame holes is small, and it can achieve full premixed combustion, reducing the demand for secondary air. Even without supplementing secondary air, that is, without entraining the air in the surrounding environment and without the blast air ejected from the middle-ring flame holes 1102 (at this time, the blower may not need to force air blowing). The porous ceramic plate is mainly prepared by infrared ceramic materials.

[0079] The above are only the preferred embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structural transformation made under the concept of the present application by using the content of the specification and drawings of the present application, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present application.
