Description

Technical Field

[0001] This utility model relates to the field of stoves, and in particular to a burner and a gas stove containing the burner. Background Technology

[0002] Currently, the demand for burner flattening has reached a design bottleneck, as the compression of individual components within the burner in the height direction has approached its limit. For example, the scheme disclosed in Chinese patent application CN110118354A uses a multi-layered stacked structure to form the necessary structures within the burner. Each layer is a necessary component of the burner, and further compression in height space will affect the normal operation and performance of the burner, leading to problems such as insufficient secondary air supply, poor combustion efficiency, incomplete combustion, excessive flue gas production, and difficulty in achieving high combustion loads. Therefore, how to overcome the current bottleneck in burner flattening requirements and achieve burner flattening while ensuring combustion efficiency and load capacity has become a key research focus for those skilled in the art. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects in the prior art and provide a burner and a gas stove containing the burner.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] A burner includes a flame cap, a partition structure, and a base, both located below the flame cap. At least a portion of the top wall of a secondary air passage of the burner is defined by the partition structure, and the remaining portion of the secondary air passage is defined by the base.

[0006] Wherein, along the axial direction of the burner, the projection of the partition structure on the burner cap is located within the range of the burner cap, and the partition structure is embedded in the burner cap;

[0007] The lower surface of the flame cap is embedded in the base.

[0008] By setting the partition structure of the top wall of the secondary air passage within the projection range of the burner cap and embedding it upwards inside the burner cap, the space inside the burner cap can be used to accommodate the partition structure. This allows the top wall of the secondary air passage to be arranged using the internal space of the burner cap, making the structure of the entire burner more compact in the height direction and achieving the goal of further flattening the burner.

[0009] Meanwhile, the base of the remaining part of the secondary air passage is set to be at least partially outside the range of the burner cap. The base is larger than the burner cap in the plane so that the lower surface of the burner cap can be embedded in the base. On the one hand, this can avoid the problem that the burner cap cannot be installed on the base if it falls and the lower surface is deformed. On the other hand, it also improves the connection and sealing between the burner cap and the base, and avoids leakage of internal gas.

[0010] Preferably, the partition structure is integrally formed with the base, and the lower surface of the flame cap is disposed on the top of the base, so that the partition structure is embedded in the flame cap.

[0011] By integrally forming the partition structure onto the base, the number of burner parts is further reduced.

[0012] Preferably, the partition structure is separately disposed from the base, the partition structure is fixed to the flame cap, and the lower surface of the flame cap is disposed on the top of the base, so that the partition structure is located on the top of the base.

[0013] By directly mounting the partition structure on the burner cap, and with the burner cap positioned on top of the base, the partition structure is also positioned on top of the base. This eliminates the need for a disc-shaped partition structure to be stacked on the base to form the top wall of the secondary air passage. As a result, a component that needs to be stacked between the base and the burner cap can be eliminated, allowing the overall height of the burner to be reduced and achieving a further flattening of the burner.

[0014] At the same time, since there is no need to stack disc-shaped partition structures on the base to form the top wall of the secondary air channel, the defects of the prior art, such as the obstruction of the upward flow of gas caused by setting disc-shaped structures on the base and the poor uniformity of gas, can be solved.

[0015] Preferably, the top of the inner wall of the flame cap has a protruding structure extending toward the partition structure, the protruding structure abutting against the upper surface of the partition structure.

[0016] Preferably, the partition structure is fixed to the protruding structure by fasteners.

[0017] Preferably, the protruding structure is located in the middle of the inner cavity of the burner along the radial direction of the burner.

[0018] Preferably, along the circumference of the burner, a plurality of the protruding structures are circumferentially spaced on the burner cap, and the spacing between adjacent protruding structures is greater than the size of the protruding structure.

[0019] Preferably, the outer edge and / or inner edge and / or upper surface of the partition structure abuts against and is positioned against the inner wall of the fire cap.

[0020] By having at least one of the outer edge, inner edge, or upper surface of the partition structure abut against the inner wall of the flame cap, the connection and positioning effect between the flame cap and the partition structure is improved, which also facilitates more precise assembly between the flame cap and the partition structure.

[0021] Preferably, the partition structure is a plate-like structure with a constant thickness.

[0022] The partition structure is made of a plate-like structure with a constant thickness, which facilitates processing and manufacturing.

[0023] Preferably, along the axial direction of the burner, the partition structure is arranged corresponding to the support legs of the pot support.

[0024] The partition structure is designed to block the chambers of the pot support, thereby reducing the gas flow rate and preventing excessive gas heat from burning the support feet of the pot support. This improves the durability of the pot support.

[0025] Preferably, the upper surface of the partition structure and the inner cavity of the burner cover form a gas passage for gas flow, and the gas passage is connected to the burner hole of the burner cover.

[0026] The upper surface of the partition structure and the inner cavity of the burner cover form a gas passage, which makes the flame distribution on the surface of the burner cover more uniform.

[0027] Preferably, the top of the inner wall of the burner cap has an inclined surface, and the angle between the inclined surface and the upper surface of the partition structure is between 25° and 35°. Along the radial direction of the burner, the flame hole is located on the outer side of the burner cap, and the inclined surface is located on the inner side of the burner cap.

[0028] By setting the angle between the inclined surface of the inner wall of the burner cap and the upper surface of the partition structure between 25° and 35°, the gas flowing through the gas passage is guided to flow towards the outside of the burner cap, thereby improving the gas flow at the burner hole.

[0029] Preferably, along the circumference of the burner, the burner cap is divided into a closed area covered by the partition structure and an open area not covered by the partition structure.

[0030] The air inlet height of the fire hole located in the closed area is higher than the air inlet height of the fire hole located in the open area.

[0031] Since the gas flows upward, by making the inlet height of the burner holes in the enclosed area higher than that of the burner holes in the open area, the upward-flowing gas can more easily enter the burner holes in the enclosed area, reducing the impact of setting up a partition structure in the enclosed area on the gas flow to the burner holes.

[0032] The diameter of the fire hole located in the closed area is larger than the diameter of the fire hole located in the open area.

[0033] The slope of the fire hole located in the closed area is greater than the slope of the fire hole located in the open area.

[0034] The distribution density of fire holes located in the closed area is greater than that of fire holes located in the open area.

[0035] For the burner holes in the enclosed area, by making at least one of the burner hole diameter, slope, and distribution density in that area greater than at least one of the burner hole diameter, slope, and distribution density in the open area, the gas can more easily enter the burner holes in the enclosed area, reducing the impact of setting up a partition structure in the enclosed area on the flow of gas to the burner holes.

[0036] There are two enclosed areas, which are symmetrically arranged on the flame cap.

[0037] The number of open areas is two, and the two open areas are symmetrically arranged on the fire cover.

[0038] The number of closed areas and open areas is multiple, and the multiple closed areas and open areas are alternately arranged on the burner cap along the circumference of the burner.

[0039] Wherein, if the number of enclosed areas is one, the area occupied by the enclosed area on the flame cover is less than or equal to 1 / 3 of the total area of ​​the flame cover.

[0040] Wherein, if there are multiple enclosed areas, the area occupied by a single enclosed area on the flame cover is less than or equal to 1 / 4 of the total area of ​​the flame cover.

[0041] By limiting the size of the enclosed area on the burner cap, insufficient gas flow rate can be avoided due to excessively large enclosed areas on the burner cap, thus affecting the burner cap's firepower.

[0042] Preferably, the flame port includes a flame stabilizer port and / or a main flame port.

[0043] Preferably, the height of the air inlet of the flame stabilizing hole located in the enclosed area is not lower than the height of the air inlet of the main fire hole.

[0044] Compared to the main burner, the flame stabilizing orifice has a smaller inlet area, resulting in greater intake resistance. Since the height of the enclosed area is lower than other areas, if the flame stabilizing orifice's inlet is arranged below the main burner's inlet, as is the conventional arrangement, the inlet will be closer to the lower partition structure. This causes the upward-flowing gas to preferentially enter the main burner, making it difficult for the flame stabilizing orifice to intake, leading to poor flame stabilization within the enclosed area. Therefore, by ensuring the height of the flame stabilizing orifice's inlet in the enclosed area is no lower than the main burner's inlet height, the ability of gas to flow into the flame stabilizing orifice's inlet within the enclosed area is improved, thus enhancing the flame stabilization effect.

[0045] Preferably, the diameter of the flame cap is less than or equal to 120 mm.

[0046] Preferably, the base and the burner cap together define the mixing chamber of the burner, and the ratio of the height of the mixing chamber to the diameter of the burner cap is in the range of 1 / 3 to 1 / 5.

[0047] A gas stove comprising a burner as described above.

[0048] The positive and progressive effects of this utility model are as follows:

[0049] The burner and the gas stove containing it, by setting the partition structure of the top wall that makes up the secondary air passage within the projection range of the burner cap and embedding it upwards into the burner cap, utilize the space inside the burner cap to accommodate the partition structure, making the structure of the entire burner more compact in the height direction and achieving the purpose of further flattening the burner.

[0050] At the same time, the lower surface of the burner cap can be embedded in the base, which can avoid the problem that the lower surface of the burner cap cannot be installed on the base if it falls and deforms. It also improves the connection and sealing between the burner cap and the base, and prevents internal gas leakage. Attached Figure Description

[0087] Gas stove 100 Detailed Implementation

[0088] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0089] Example 1

[0090] like Figure 1 As shown, this utility model provides a gas stove 100, which includes a burner 10 located on the upper surface of a liquid tray 20. Gas flows out from the flame holes on the surface of the burner cap 1 of the burner 10, and combustion produces a flame, which heats the bottom of the pot to achieve the purpose of cooking. A pot support 30 is provided around the burner 10, and four support legs 301 are distributed on the pot support 30. The four support legs 301 jointly support the bottom of the pot. At the same time, the pot support 30 is arranged circumferentially around the burner 10 to form an energy-concentrating plate, so that the heat generated by the flame can be concentrated at the bottom of the pot.

[0091] like Figure 2 and Figure 3 As shown, in this embodiment, a secondary air channel 4 is provided on the peripheral surface of the burner 10. The secondary air channel 4 is connected inward along the horizontal direction to the space between the inner ring and the outer ring of the burner 10, so that external air can be replenished to the space between the inner ring and the outer ring through the secondary air channel 4.

[0092] like Figure 3As shown, the outer ring portion of the burner 10 specifically includes a flame cap 1 and a base 2. The flame cap 1 is disposed on the base 2 to jointly enclose a mixing chamber 5 for gas flow. In this embodiment, the burner 10 also includes a partition structure 3, with both the partition structure 3 and the base 2 located below the flame cap 1. The top wall of the secondary air passage 4 is defined by the partition structure 3, while the remaining portion of the secondary air passage 4 is defined by the base 2.

[0093] Figure 4a and Figure 4b Cross-sectional views of the burner 10 at different locations are shown, such as... Figure 4a As shown, along the axial direction (i.e., vertical direction) of the burner 10, the projection of the partition structure 3 onto the burner cap 1 is entirely within the area of ​​the burner cap 1, and the partition structure 3 is embedded within the burner cap 1 in the upward direction. Meanwhile, as... Figure 4b As shown, the projection of the base 2 onto the flame cap 1 is at least partially outside the range of the flame cap 1, that is, at least part of the periphery of the base 2 protrudes outward from the flame cap 1 in the horizontal direction, and the lower surface of the flame cap 1 is embedded in the base 2, and the flame cap 1 is limited by the flange 21 on the base 2.

[0094] By setting the partition structure 3 of the top wall of the secondary air passage 4 within the projection range of the flame cap 1 and embedding it upwards into the flame cap 1, the space inside the flame cap 1 can accommodate the partition structure 3. This allows the top wall of the secondary air passage 4 to be arranged using the internal space of the flame cap 1, making the structure of the entire burner 10 more compact in the height direction and achieving the goal of further flattening the burner 10.

[0095] Meanwhile, the base 2, which constitutes the remaining part of the secondary air passage 4, is set to be at least partially located outside the range of the burner cap 1. The base 2 is larger in size on the plane than the burner cap 1, so that the lower surface of the burner cap 1 can be embedded in the base 2. On the one hand, this can avoid the problem that the burner cap 1 cannot be installed on the base 2 if it falls and the lower surface is deformed. On the other hand, it also improves the sealing of the connection between the burner cap 1 and the base 2, and avoids leakage of internal gas.

[0096] In this embodiment, the entire top wall of the secondary air channel 4 is defined by the partition structure 3. In other embodiments, the partition structure 3 may only define a portion of the top wall of the secondary air channel 4. For example, the partition structure 3 may form the middle part of the top wall of the secondary air channel 4, and the base 2 may define the remaining part of the top wall of the secondary air channel 4. The specific structural configuration can be configured as needed according to the actual structural configuration requirements.

[0097] In this embodiment, as Figure 5 and Figure 6As shown, the partition structure 3 and the base 2 are separate. The partition structure 3 is first installed inside the flame cap 1, and the flame cap 1 is installed on the base 2. The flame cap 1 is limited by the flange 21 on the base 2 to realize the combination of the partition structure 3 and the base 2. The partition structure 3 and the base 2 together form the channel wall of the secondary air channel 4.

[0098] Specifically, such as Figure 7 As shown, the two partition structures 3 correspond to the secondary air passages 4 on both sides of the burner 10, forming the top wall portion of the two secondary air passages 4. In this embodiment, the two partition structures 3 are installed and fixed upward along the axial direction of the burner 10 within the burner cap 1, forming a gas passage 34 for gas flow between the upper surface 33 of the partition structure 3 and the inner cavity of the burner cap 1, allowing the gas to flow into the gas passage 34 above the partition structure 3 and exit from the flame hole located in the area where the partition structure 3 is located (i.e., within the enclosed area 14). Then, as... Figure 8 As shown, the burner cap 1 with two partition structures 3 is installed downward along the axial direction of the burner 10 on the top of the base 2, so that the two partition structures 3 are located on the top of the base 2, and the base 2 and the two partition structures 3 respectively form a secondary air channel 4.

[0099] By directly mounting the partition structure 3 on the burner cap 1, and with the burner cap 1 positioned on top of the base 2, the partition structure 3 is also positioned on top of the base 2. This eliminates the need for the burner 10 to have a disc-shaped partition structure 3 stacked on the base 2 to form the top wall of the secondary air passage 4. As a result, a part that needs to be stacked between the base 2 and the burner cap 1 can be eliminated, allowing the overall height of the burner 10 to be reduced and achieving a further flattening of the burner 10.

[0100] Meanwhile, since it is no longer necessary to stack a disc-shaped partition structure 3 on the base 2 to form the top wall of the secondary air channel 4, the defects of the prior art, such as the obstruction of the upward flow of gas caused by setting a disc-shaped structure on the base 2 and the poor uniformity of gas, can be solved.

[0101] like Figure 9 As shown, in this embodiment, the partition structure 3 is a plate-like structure with a constant thickness to facilitate manufacturing. To achieve the purpose of fixing the partition structure 3 to the flame cap 1, a protruding structure 12 extending towards the partition structure 3 is provided on the top of the inner wall 11 of the flame cap 1, as shown... Figure 4aAs shown, these protruding structures 12 abut against the upper surface 33 of the partition structure 3. To reliably fix the partition structure 3 to the flame cap 1, in this embodiment, the fastener passes through the partition structure 3 from bottom to top and fixes the partition structure 3 to the protruding structures 12 by means of thread. This connection scheme allows for easy assembly and disassembly of the partition structure 3 relative to the flame cap 1, and ensures reliable connection when fixed. Specifically, in this embodiment, a countersunk hole is provided on the lower surface of the partition structure 3, and the head of the fastener is recessed into the countersunk hole.

[0102] like Figure 9 As shown, the burner cap 1 has two protruding structures 12 corresponding to the partition structure 3 for fixation. Along the radial direction of the burner 10, the protruding structures 12 are located at the middle position of the inner cavity of the burner cap 1. At the same time, along the circumferential direction of the burner 10, the protruding structures 12 are circumferentially spaced on the burner cap 1, and the distance between two adjacent protruding structures 12 is greater than the size of the protruding structure 12.

[0103] These protruding structures 12 protrude within the gas passage 34 of the burner cap 1 to turbulent the airflow and improve the mixing degree of the gas and primary air. At the same time, by distributing the two protruding structures 12 at a large distance (i.e., the distance is greater than the size of the protruding structure 12 itself), the gaps between the protruding structures 12 are not too small, which would cause turbulence in the gas.

[0104] In this embodiment, to improve the fixing effect between the protruding structure 12 and the flame cap 1, such as Figure 4a As shown, the upper surface 33 of the partition structure 3 abuts against the protruding structure 12 of the inner wall 11 of the flame cap 1, the outer edge 31 of the partition structure 3 abuts against the outer side of the inner wall 11 of the flame cap 1, and the inner edge 32 of the partition structure 3 abuts against the inner side of the inner wall 11 of the flame cap 1. This improves the connection and positioning effect between the flame cap 1 and the partition structure 3, and also facilitates more precise assembly between the flame cap 1 and the partition structure 3. In other embodiments, at least one of the outer edge 31, inner edge 32, and upper surface 33 of the partition structure 3 can abut against the flame cap 1 for positioning.

[0105] In this embodiment, partition structures 3 are provided on both sides of the burner cap 1. The positions of these two partition structures 3 on the burner cap 1 correspond exactly to two of the four support legs 301 of the pot support 30. The partition structures 3 are provided corresponding to the support legs 301 of the pot support 30 to block the chamber, reduce the gas flow rate at that point, and prevent the gas flame from being too strong and burning the support legs 301 of the pot support 30. Therefore, the durability of the pot support 30 can be improved.

[0106] like Figure 4aAs shown, in this embodiment, the top of the inner wall 11 of the burner cap 1 has an inclined surface 111, the angle between the inclined surface 111 and the upper surface 33 of the partition structure 3 is 30°, and along the radial direction of the burner 10, the flame hole is located on the outer side of the burner cap 1, while the inclined surface 111 is located on the inner side of the burner cap 1. By setting the angle between the inclined surface 111 at the top of the inner wall 11 of the burner cap 1 and the upper surface 33 of the partition structure 3 at 30°, the gas flowing through the gas passage 34 is guided, causing the gas to flow towards the outer side of the burner cap 1, thereby improving the gas flow at the flame hole. In other embodiments, the above-mentioned clamp can also adopt other angle ranges, preferably between 25° and 35°, to ensure that the inclined surface 111 can guide the upward flowing gas, causing the gas to flow towards the outer side of the burner cap 1, thereby improving the gas flow at the flame hole.

[0107] In this embodiment, the diameter of the burner cap 1 is preferably less than or equal to 120 mm to achieve a compact layout of the burner 10, concentrate firepower, and ensure overall high efficiency of the burner 10. Furthermore, the base 2 and the burner cap 1 together define the mixing chamber 5 of the burner 10, and the ratio of the height of the mixing chamber 5 to the diameter of the burner cap 1 is approximately 1 / 4. Given a fixed upper limit for the diameter of the burner cap 1, by making the height of the mixing chamber 5 approximately 1 / 4 of the diameter of the burner cap 1, excessive height of the mixing chamber 5 is avoided, which would affect the overall height of the burner 10. In other embodiments, the ratio of the height of the mixing chamber 5 to the diameter of the burner cap 1 can also be in the range of 1 / 3 to 1 / 5.

[0108] In this embodiment, two partition structures 3 are installed on the flame cap 1. These two partition structures 3 correspond to two secondary air channels 4 and are symmetrically arranged on the flame cap 1. The number of corresponding open areas 15 is also two, and the two open areas 15 are symmetrically arranged on the flame cap 1.

[0109] like Figure 10 As shown, along the circumference of the burner 10, the burner cap 1 is divided into a closed area 14 covered by the partition structure 3 and an open area 15 not covered by the partition structure 3. The closed area 14 and the open area 15 are alternately arranged on the burner cap 1 along the circumference of the burner 10.

[0110] Compare Figure 12 and Figure 13 It can be seen that, for the enclosed area 14 of the burner cap 1, since it is covered by the partition structure 3, the height of the internal gas passage 34 is significantly smaller than the height of the mixing chamber 5 composed of the burner cap 1 and the base 2. Therefore, the gas supply and flow rate in the enclosed area 14 of the burner cap 1 are relatively insufficient.

[0111] To address the gas combustion differences caused by the aforementioned structural variations, this solution also makes targeted adjustments to the flame hole structure in different areas of the burner cap 1. Specifically, the flame holes on the burner cap 1 include main flame holes and flame stabilizing holes. The main flame hole has a larger channel size and is mainly used for heating the bottom of the pot. The flame stabilizing hole has a smaller channel size and is located close to the main flame hole to stabilize the flame of the main flame hole, preventing backfire or flame lift-off.

[0112] In this embodiment, as Figure 11 As shown, the inlet height of the flame stabilizing hole 141a located in the enclosed region 14 is higher than the inlet height of the flame stabilizing hole 141b located in the open region 15. This is because the combustion gas flows upward. For the burner holes in the enclosed region 14, by making the inlet height of the flame stabilizing hole 141a higher than the inlet height of the flame stabilizing hole 141b in the open region 15, the upward-flowing combustion gas can more easily enter the flame stabilizing hole 141a in the enclosed region 14, reducing the impact of the partition structure 3 in the enclosed region 14 on the flow of combustion gas to the burner holes. In addition, in this embodiment, the inlet height of the main burner hole 131a located in the enclosed region 14 is equal to the inlet height of the main burner hole 131b located in the open region 15. Of course, in other embodiments, the inlet height of the main burner hole 131a located in the enclosed region 14 can also be higher than the inlet height of the main burner hole 131b located in the open region 15, making it relatively easier for the combustion gas to enter the main burner hole in the enclosed region 14. In this embodiment, the air inlet of the flame stabilizing hole 141a within the enclosed area 14 is relatively higher, while the air inlet height of the main burner hole 131a remains unchanged. This is mainly because the flow rate of gas entering the gas passage 34 is limited. By raising the air inlet of the flame stabilizing hole 141a within the enclosed area 14, the gas flow rate of the flame stabilizing hole 141a is prioritized, ensuring a stable flame effect. In other embodiments, adjustments can be made as needed based on actual requirements.

[0113] In this embodiment, the outlet height of the flame stabilizing hole 141a located in the closed region 14 is the same as the outlet height of the flame stabilizing hole 141b located in the open region 15, making the flame hole of the flame stabilizing hole 141a located in the closed region 14 more inclined, and the slope of the flame stabilizing hole 141a in the closed region 14 is greater than the slope of the flame stabilizing hole 141b in the open region 15.

[0114] Of course, the structural adjustment of the flame stabilizing holes in different regions in this embodiment is only a preferred structural configuration. In other embodiments, to improve the flame performance within the enclosed region 14, the aperture of the flame holes in the enclosed region 14 can be set to be larger than the aperture of the flame holes in the open region 15. Alternatively, the distribution density of the flame holes in the enclosed region 14 can be set to be greater than the distribution density of the flame holes in the open region 15. The specific structural configuration can be adjusted as needed according to actual requirements, so that the gas can more easily enter the flame holes in the enclosed region 14, reducing the impact of the partition structure 3 in the enclosed region 14 on the flow of gas to the flame holes.

[0115] Specifically, the enclosed area 14 of the burner cap 1 should not occupy too large an area on the burner cap 1 to avoid insufficient gas flow rate due to an excessively large enclosed area 14, which would affect the flame strength of the burner cap 1. When two enclosed areas 14 are provided on the burner cap 1, the area occupied by each enclosed area 14 should be less than or equal to 1 / 4 of the total area of ​​the burner cap 1. In other embodiments, when only a single enclosed area 14 is provided on the burner cap 1, the area occupied by that enclosed area 14 should be less than or equal to 1 / 3 of the total area of ​​the burner cap 1.

[0116] like Figure 12 As shown, in the enclosed area 14 of the burner cap 1 in this embodiment, the height of the air inlet of the flame stabilizing hole 141a should not be lower than the height of the air inlet of the main burner hole 131a. This is because the air inlet area of ​​the flame stabilizing hole 141a is smaller than that of the main burner hole 131a, resulting in greater air intake resistance. Since the height of the space within the enclosed area 14 is lower than other areas, if the arrangement of the flame stabilizing hole's air inlet is still the conventional arrangement of being located below the main burner hole's air inlet, the flame stabilizing hole will be closer to the lower partition structure, and the upward-flowing gas flow will preferentially enter the main burner hole, making it difficult for the flame stabilizing hole to intake air, resulting in poor flame stabilization within the enclosed area 14. Therefore, by ensuring that the height of the air inlet of the flame stabilizing hole located in the enclosed area 14 is not lower than the height of the main burner hole's air inlet, the ability of gas to flow into the air inlet of the flame stabilizing hole within the enclosed area 14 is improved, thereby enhancing the flame stabilization effect of the enclosed area 14.

[0117] The burner 10 and the gas stove 100 containing it are designed to be more compact in height by placing the partition structure 3 of the top wall of the secondary air passage 4 within the projection range of the burner cap 1 and embedding it upwards into the burner cap 1. This utilizes the space within the burner cap 1 to accommodate the partition structure 3, achieving a further flattening of the burner 10. Simultaneously, this allows the lower surface of the burner cap 1 to be embedded in the base 2, preventing the burner cap 1 from falling and deforming, thus ensuring proper installation on the base 2. It also improves the sealing of the connection between the burner cap 1 and the base 2, preventing internal gas leakage.

[0118] Example 2

[0119] like Figure 14 and Figure 15 As shown, this embodiment also provides a gas stove 100, the structure of which is roughly the same as that of the burner 10 in embodiment 1. The main difference is that in this embodiment, the two partition structures 3 and the base 2 are integrally formed, the partition structure 3 is directly formed on the top of the base 2, the partition structure 3 constitutes the top wall of the secondary air channel 4, and the base 2 constitutes the rest of the secondary air channel 4.

[0120] like Figure 15 As shown, the burner cap 1 is mounted downwards along the axial direction of the burner 10 on the base 2. The partition structure 3 is embedded inside the burner cap 1, and the lower surface of the burner cap 1 is embedded inside the base 2. The lower surface of the burner cap 1 is limited by the flange 21 of the base 2. By embedding the partition structure 3, the burner cap 1, and the base 2 in the above-described manner, on the one hand, part of the partition structure 3 is embedded inside the burner cap 1, so that the space inside the burner cap 1 can accommodate the partition structure 3. This allows the top wall of the secondary air passage 4 to be arranged using the internal space of the burner cap 1, making the structure of the entire burner 10 more compact in the height direction and achieving the goal of further flattening the burner 10. On the other hand, the lower surface of the burner cap 1 can be embedded inside the base 2 to improve the sealing of the connection between the burner cap 1 and the base 2, preventing internal gas leakage.

[0121] In this embodiment, the gas stove 100 can also be controlled by a voice module, which is equipped with a controller, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the gas stove 100 to perform corresponding operations, thereby realizing intelligent control of the gas stove 100 and improving the user experience.
