In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0038] This embodiment provides a burner with high safety and reliability. The burner in this embodiment can be used in a gas stove or other equipment.

[0039] like Figures 1 to 6 As shown, the burner includes an inner ring fire cover 100, an outer ring fire cover 200 and a gas distributor 300. The inner ring fire cover 100 is arranged on one side of the outer ring fire cover 200. For example, the inner ring fire cover 100 is arranged on one side of the outer ring fire cover 200 in the thickness direction. In addition, the inner ring fire cover 100 and the outer ring fire cover 200 are detachably connected, so that the inner ring fire cover 100 and the outer ring fire cover 200 can be connected into a whole. In this embodiment, by detachably connecting the inner ring fire cover 100 and the outer ring fire cover 200, the manufacturing difficulty of the inner ring fire cover 100 and the outer ring fire cover 200 can be reduced, which facilitates the batch manufacturing of the inner ring fire cover 100 and the outer ring fire cover 200 and improves the production efficiency of the burner.

[0040] In some optional embodiments, the inner ring fire cover 100 is connected to the outer ring fire cover 200 through a connecting piece. The inner ring fire cover 100 is provided with a first threaded hole 150, and the outer ring fire cover 200 is provided with a first locking hole 221. The connecting piece passes through the first locking hole 221 and is screwed into the first threaded hole 150 to connect the outer ring fire cover 200 and the inner ring fire cover 100. For example, the connecting piece is a bolt. The nut of the bolt is limited to the side of the outer ring fire cover 200 away from the inner ring fire cover 100 so as not to affect the aesthetics of the inner ring fire cover 100.

[0041] like Figure 1 or Figure 2 As shown, the gas distributor 300 is arranged on the other side of the outer ring fire cover 200. For example, the gas distributor 300 is arranged on the other side in the thickness direction of the outer ring fire cover 200. In addition, the gas distributor 300 is fixedly connected to the outer ring fire cover 200, so that the gas distributor 300 and the outer ring fire cover 200 are connected as a whole, and then the inner ring fire cover 100, the outer ring fire cover 200 and the gas distributor 300 can be connected as a whole, thereby improving the integrity of the burner.

[0042] It should be noted that the fixed connection between the gas separation seat 300 and the outer ring fire cover 200 can be a detachable connection or a non-detachable connection between the gas separation seat 300 and the outer ring fire cover 200, and this embodiment does not limit this. Preferably, the fixed connection between the gas separation seat 300 and the outer ring fire cover 200 is a detachable connection, which can facilitate the manufacture of the gas separation seat 300 and the outer ring fire cover 200 on the one hand, and facilitate the cleaning of the gas separation seat 300 and the outer ring fire cover 200 on the other hand.

[0043] In some optional embodiments, the gas separation seat 300 is detachably connected to the outer ring fire cover 200 through a connecting piece, the gas separation seat 300 is provided with a second locking hole 330, and the outer ring fire cover 200 is provided with a second threaded hole 280. The connecting piece passes through the second locking hole 330 and is screwed into the second threaded hole 280 to achieve the connection between the gas separation seat 300 and the outer ring fire cover 200. The connecting piece can be a bolt, and the nut of the bolt connecting the gas separation seat 300 and the outer ring fire cover 200 is located on the side of the gas separation seat 300 away from the outer ring fire cover 200, so as to facilitate the assembly of the gas separation seat 300 and the outer ring fire cover 200, and will not affect the aesthetics of the outer ring fire cover 200.

[0044] The burner provided in the present embodiment includes an inner ring fire cover 100, an outer ring fire cover 200 and an air dividing seat 300. The inner ring fire cover 100 is arranged on one side of the outer ring fire cover 200 and is detachably connected to the outer ring fire cover 200. The air dividing seat 300 is fixedly connected to the outer ring fire cover 200, so that the inner ring fire cover 100, the outer ring fire cover 200 and the air dividing seat 300 can be connected into a whole, thereby reducing the probability of the inner ring fire cover 100 being improperly placed on the outer ring fire cover 200, and also reducing the probability of the outer ring fire cover 200 being improperly placed on the air dividing seat 300, thereby reducing the probability of gas leakage, fire leakage and deflagration of the burner due to improper assembly, thereby improving the safety and reliability of the burner.

[0045] Furthermore, the integrated design of the inner ring fire cover 100, the outer ring fire cover 200 and the gas distributor seat 300 can facilitate the user to take and place them, and has a high fool-proof effect.

[0046] In addition, the integrated design of the inner ring fire cover 100, the outer ring fire cover 200 and the gas distributor seat 300 also simplifies the overall structure of the burner, so that the weight of the burner can be lower, and the cost is reduced without changing the performance.

[0047] Alternatively, if Figure 2 As shown, the outer ring fire cover 200 is provided with a fire cover central channel 210, and the fire cover central channel 210 is used for gas flow. For example, the fire cover central channel 210 is arranged at the center of the outer ring fire cover 200. For another example, one end of the fire cover central channel 210 can be connected to a gas source, so that the mixed gas and air can enter the fire cover central channel 210.

[0048] Please continue to see Figure 2 , the inner wall of the central channel 210 of the fire cover is connected with a channel transverse rib 220, and the inner ring fire cover 100 is detachably connected to the channel transverse rib 220. In this embodiment, the provision of the channel transverse rib 220, on the one hand, facilitates the detachable connection between the outer ring fire cover 200 and the inner ring fire cover 100, and also facilitates the connection of the inner ring fire cover 100 to the central channel 210 of the outer ring fire cover 200, so that the gas in the central channel 210 of the fire cover can flow to the fire outlet hole 140 on the inner ring fire cover 100; on the other hand, the channel transverse rib 220 will not occupy the area of ​​the outer ring fire cover 200 for setting the fire outlet hole 140, and can also have a small impact on the flow area of ​​the central channel 210 of the fire cover.

[0049] In some optional embodiments, such as Figure 5 As shown, both ends of the channel cross rib 220 in the length direction are connected to the inner wall of the fire cover central channel 210 to improve the connection reliability and stability between the inner ring fire cover 100 and the outer ring fire cover 200. Of course, it can be understood that the channel cross rib 220 can also be connected to the inner wall of the fire cover central channel 210 at one end in the length direction, and this embodiment is not limited to this.

[0050] Optionally, see Figure 5 The outer ring fire cover 200 is provided with a compensation port 201, which is used to compensate for the reduction in the flow area of ​​the central channel 210 of the fire cover caused by the provision of the channel cross ribs 220, so that the central channel 210 of the fire cover can still provide sufficient gas to the fire outlet 140 on the inner ring fire cover 100. In this embodiment, the gas in the central channel 210 of the fire cover located on the side of the channel cross ribs 220 away from the inner ring fire cover 100 can flow out of the central channel 210 of the fire cover through the compensation port 201, so as to achieve the purpose of compensation.

[0051] For example, the compensation opening 201 extends to the end surface of the outer ring fire cover 200 close to the inner ring fire cover 100 to achieve a better compensation effect.

[0052] Further optionally, if Figure 5As shown, the outer ring fire cover 200 is provided with a functional hole 202, and the compensation port 201 is arranged opposite to and connected to the functional hole 202, so that the gas in the central channel 210 of the fire cover can smoothly flow to the functional hole 202 through the compensation port 201, ensuring that the gas at the functional hole 202 is sufficient and reducing the flow resistance. It should be noted that the functional hole 202 can be an ignition hole or a fire-keeping hole, or there are two functional holes 202, one of which is an ignition hole and the other is a fire-keeping hole, and the compensation port 201 is opposite to both functional holes 202.

[0053] Alternatively, if Figure 4 As shown, the outer ring fire cover 200 is also provided with a fire cover radiation channel 231 and a fire cover annular channel 232. The fire cover annular channel 232 is arranged around the fire cover central channel 210, and the fire outlet holes 140 on the outer ring fire cover 200 are connected to the fire cover annular channel 232, that is, the part of the outer ring fire cover 200 where the fire outlet holes 140 are arranged is surrounded to form the fire cover annular channel 232. The fire cover radiation channel 231 is connected between the fire cover annular channel 232 and the fire cover central channel 210, so that the gas in the fire cover central channel 210 can flow to the fire cover annular channel 232 through the fire cover radiation channel 231.

[0054] For example, at least two fire cover radiation channels 231 are provided, and the at least two fire cover radiation channels 231 are spaced and evenly arranged in the circumferential direction of the fire cover central channel 210 to improve the uniformity of gas distribution in the fire cover annular channel 232, thereby improving the uniformity of burner combustion. In this embodiment, three fire cover radiation channels 231 are provided.

[0055] Optionally, the fire cover radiation channel 231 and the fire cover annular channel 232 can both be groove structures. After the outer ring fire cover 200 is connected to the gas separation seat 300, the gas separation seat 300 can block the notch of the groove to form a relatively independent channel structure. Of course, it can be understood that the fire cover radiation channel 231 and the fire cover annular channel 232 can also be through-hole structures, which is not limited in this embodiment.

[0056] In some optional embodiments, such as Figure 6As shown, the gas separation seat 300 is provided with a gas separation center channel 310, a gas separation radiation channel 321 and a gas separation annular channel 322. Among them, the gas separation annular channel 322 is arranged around the gas separation center channel 310, and the gas separation radiation channel 321 is connected between the gas separation center channel 310 and the gas separation annular channel 322, so that the gas in the gas separation center channel 310 can flow to the gas separation annular channel 322 through the gas separation radiation channel 321. The gas separation center channel 310 is connected with the fire cover center channel 210, so that the gas in the gas separation center channel 310 can flow to the fire cover center channel 210. The gas separation annular channel 322 is used to provide gas to the fire outlet 140 on the outer ring fire cover 200. For example, the gas separation annular channel 322 is connected with the fire cover annular channel 232.

[0057] Optionally, the fire cover annular channel 232 is directly opposite to and connected to the gas distribution annular channel 322, so that the two cooperate to form a larger channel structure, thereby ensuring the gas volume at the fire outlet 140 and further ensuring the combustion stability of the burner.

[0058] Further optionally, the number of the gas distribution radiation channels 321 is the same as the number of the fire cover radiation channels 231, and when the gas distribution seat 300 is connected to the outer ring fire cover 200, the gas distribution radiation channels 321 are correspondingly connected to the fire cover radiation channels 231 to form a channel structure with a larger flow area, which can increase the amount of gas delivered to the fire cover annular channel 232.

[0059] Optionally, the outer ring fire cover 200 is an integrally formed structure, that is, the outer ring fire cover 200 can be manufactured in a one-time manufacturing process to have higher structural strength and integrity.

[0060] Further optionally, if Figure 5 As shown, the outer ring fire cover 200 includes an inner ring portion 240, an outer ring portion 250, and a connecting portion 260 connected between the inner ring portion 240 and the outer ring portion 250, which are arranged concentrically. The inner ring fire cover 100 is detachably connected to the inner ring portion 240, and the gas separation seat 300 is fixedly connected to the outer ring portion 250 or the connecting portion 260, so that the connection position of the inner ring fire cover 100 and the outer ring fire cover 200 is different from the connection position of the gas separation seat 300 and the outer ring fire cover 200, which reduces the assembly interference between the structures and facilitates the assembly of the burner.

[0061] In this embodiment, a plurality of connection parts 260 are provided, and the plurality of connection parts 260 are arranged at intervals along the circumference of the inner ring part 240, so that the outer ring fire cover 200 is hollow, thereby making the weight of the outer ring fire cover 200 smaller, which is conducive to the lightweighting of the burner.

[0062] It should be noted that the fire outlet holes 140 on the outer ring fire cover 200 are arranged on the outer ring portion 250, and the fire cover central channel 210 is arranged on the inner ring portion 240, that is, the channel transverse ribs 220 are connected to the inner ring portion 240. The outer ring portion 250 is provided with a fire cover annular channel 232, and the connecting portion 260 is provided with a fire cover radiation channel 231, that is, a plurality of connecting portions 260 and fire cover radiation channels 231 are arranged one by one, and each fire cover radiation channel 231 is arranged on the corresponding connecting portion 260.

[0063] Alternatively, if Figure 5 As shown, the inner ring portion 240 of the outer ring fire cover 200 includes a main body 241 and an inner ring body 242 and an outer ring body 243 coaxially arranged on the same side of the main body 241. Among them, the outer ring body 243 is arranged on the outer periphery of the inner ring body 242, and the inner ring fire cover 100 is detachably connected to the inner ring body 242, that is, the channel cross rib 220 is connected to the inner ring body 242. It should be noted that a part of the fire cover central channel 210 is arranged on the main body 241, and the other part is arranged on the inner ring body 242.

[0064] Further optionally, if Figure 3 As shown, the inner ring fire cover 100 includes a cover body 110 and an annular protrusion 120 arranged on one side of the cover body 110. The annular protrusion 120 is in radial contact with the inner ring body 242 to form a radial seal to prevent gas from leaking through the gap between the annular protrusion 120 and the inner ring body 242. It should be noted that the radial contact between the annular protrusion 120 and the inner ring body 242 can be that the outer side surface of the annular protrusion 120 is tightly fitted with the inner side surface of the inner ring body 242, or the inner side surface of the annular protrusion 120 is tightly fitted with the outer side surface of the inner ring body 242, and this embodiment is not limited to this.

[0065] In this embodiment, one end of the outer ring body 243 away from the main body 241 contacts the cover body 110, so that the outer ring body 243, the main body 241 and the cover body 110 can be surrounded to form a relatively sealed space, further reducing the probability of gas leakage and improving the safety of the burner.

[0066] In this embodiment, the cover body 110 is detachably connected to the inner ring body 242. Figure 3 As shown, the cover body 110 is provided with a first threaded hole 150 , the channel transverse rib 220 is provided with a first locking hole 221 , and one end of the locking member 400 passes through the first locking hole 221 and is screwed into the first threaded hole 150 .

[0067] Please continue to see Figure 3 The fire outlet hole 140 on the inner ring fire cover 100 is arranged on the cover body 110 and is connected with the space enclosed by the annular protrusion 120 , so that the gas in the central channel 210 of the fire cover can enter the fire outlet hole 140 after passing through the space enclosed by the annular protrusion 120 .

[0068] Optionally, one of the inner ring fire cover 100 and the outer ring fire cover 200 is provided with a limiting groove 130, and the other is provided with a limiting protrusion 270. The limiting protrusion 270 can be limited in the limiting groove 130 to realize the positioning assembly of the inner ring fire cover 100 and the outer ring fire cover 200, thereby ensuring the relative position of the inner ring fire cover 100 and the outer ring fire cover 200 after assembly, and having a certain degree of fool-proofness.

[0069] Further optionally, the annular protrusion 120 of the inner ring fire cover 100 is provided with a limiting groove 130, and the limiting protrusion 270 is arranged between the outer ring body 243 and the inner ring body 242, and is connected to the main body 241 and the outer ring body 243, so that the limiting protrusion 270 will not occupy the flow area of ​​the central channel 210 of the fire cover.

[0070] Optionally, the specific structure of the gas distribution seat 300 in this embodiment may be similar to the structure of the outer ring fire cover 200, except that the gas distribution seat 300 is not provided with the fire outlet hole 140. Figure 6 As shown, the air distributor 300 is provided with a hollow structure 340 , so that the weight of the air distributor 300 can be relatively small.

[0071] In this embodiment, Figure 7 As shown, the burner also includes a burner head 500, an ignition needle 600 and a thermocouple 700. The burner head 500 is sealed and connected to the gas distributor seat 300, and the fuel channel in the burner head 500 is connected to the gas distributor center channel 310 of the gas distributor seat 300. The burner head 500 is connected to the gas distributor seat 300, the gas distributor seat 300, the inner ring fire cover 100 and the outer ring fire cover 200 to form an integrated burner. The ignition needle 600 and the thermocouple 700 are both arranged on the burner head 500, the ignition needle 600 is arranged opposite to one functional hole 202, and the thermocouple 700 is arranged opposite to another functional hole 202.
