Description

Technical Field

[0001] This application relates to the technical field of gas stoves, and in particular, to a burner and a gas stove of a gas stove. Background Art

[0002] The burners of existing gas stoves generally have fixed sizes and structures. The burners with such structures have fixed flame combustion areas during use, resulting in problems such as uneven heating and local heating at the bottom of the pot when the burners are used to heat cooking utensils with different diameters. Summary of the Invention

[0003] This application provides a burner and a gas stove of a gas stove, so that the burner can be suitable for cooking utensils with different diameters.

[0004] The first aspect of this application provides a burner of a gas stove, which includes:

[0005] A plurality of slidable combustion parts, and the combustion parts are provided with fire holes.

[0006] The above-mentioned burner includes a plurality of slidable combustion parts. The plurality of combustion parts are arranged in sequence to jointly form the burner. The combustion parts are provided with fire holes. When the combustion parts slide, the fire holes slide together with the combustion parts, so as to adjust the flame distribution of the burner, so that the burner can be better suitable for cooking utensils with different diameters or types (such as flat-bottomed pans and round-bottomed pans), so that different diameters or types of cooking utensils can be heated evenly.

[0007] In addition, the fire holes slide together with the combustion parts, and the flame distribution of the burner can be adjusted without changing the number of fire holes, so that the flame distribution of the burner can be changed to the greatest extent with a smaller number of fire holes set.

[0008] Optionally, the combustion part includes a first fire hole area and a second fire hole area, and the fire holes are arranged in the first fire hole area and the second fire hole area;

[0009] Within the sliding stroke of the combustion part, the combustion part has a first position and a second position;

[0010] When the combustion part is in the first position, there is a flame in the first fire hole area and no flame in the second fire hole area;

[0011] When the combustion part is in the second position, there are flames in both the first fire hole area and the second fire hole area.

[0012] The gas volume that the flame outlet holes of the burner can stably and completely burn is called the combustion capacity of the flame holes. The combustion capacity of the flame holes is usually expressed by the heat intensity of the flame holes. When the heat load is constant, the heat intensity of the flame holes is inversely proportional to the total area of the flame holes. The above burner can reasonably adjust the flame state of the flame outlet holes according to the size of the burner, so that the flame area of the burner can adapt to the diameter of the cooking utensil, making different diameters or types of cooking utensils evenly heated during heating and further improving the cooking efficiency.

[0013] In addition, for an atmospheric burner, the heat intensity of the flame holes needs to be controlled within a suitable range to enable the gas to burn fully and stably with a low CO content.

[0014] When the combustion part is in the first position, there is a flame in the first flame hole area, and the heat intensity of the flame holes can be controlled within a suitable range; by sliding the combustion part, when the combustion part is in the second position, there are flames in both the first flame hole area and the second flame hole area, the total area of the flame outlet holes increases, the heat intensity of the flame holes decreases, the combustion of the gas will be more complete, and the CO content will be further reduced, greatly improving the combustion performance of the burner.

[0015] Optionally, the combustion part includes an air chamber, and the flame outlet holes communicate with the air chamber;

[0016] A partition is provided in the air chamber, and the air chamber is divided into a first chamber and a second chamber by the partition;

[0017] The first flame hole area is located on the side wall of the first chamber, and the flame outlet holes provided in the first flame hole area communicate with the first chamber;

[0018] The second flame hole area is located on the side wall of the second chamber, and the flame outlet holes provided in the second flame hole area communicate with the second chamber.

[0019] The above burner can control the flame conditions of the corresponding flame outlet holes by controlling the gas inlet conditions of the first chamber and the second chamber; by reasonably setting the shapes and relative positional relationships of the first chamber and the second chamber, the first flame hole area and the second flame hole area can be distributed at appropriate positions, so that the flame area is more reasonably distributed.

[0020] Optionally, the air chamber is provided with an air inlet structure, and the air inlet structure includes a first air inlet part and a second air inlet part that are separated from each other;

[0021] The first air inlet part communicates with the first chamber, and the second air inlet part communicates with the second chamber;

[0022] When the combustion part is in the first position, the first air inlet part is opened and the second air inlet part is closed;

[0023] When the combustion part is in the second position, both the first air inlet part and the second air inlet part are opened.

[0024] Optionally, the burner further includes a base, and the combustion part is slidably connected to the base.

[0025] The base of the above burner is used to connect to the cooking top of the gas stove. The combustion part is slidably connected to the base, making the burner have high integrity and versatility. That is to say, the base can adapt to the cooking top of the gas stove and be fixed on the cooking top of the gas stove. Multiple combustion parts are arranged in sequence along the base and can slide along the base without changing the original shape of the cooking top of the gas stove.

[0026] Optionally, the base is provided with a ventilation part;

[0027] When the combustion part is in the first position, the first air inlet part communicates with the ventilation part and is opened, and the second air inlet part isolates the ventilation part and is closed;

[0028] When the combustion part is in the second position, both the first air inlet part and the second air inlet part communicate with the ventilation part and are opened.

[0029] Optionally, the air inlet structure is an air inlet hole, and the air inlet hole is arranged on the side of the combustion part facing the base;

[0030] The ventilation part is a ventilation hole, and the ventilation hole is arranged on the side of the base facing the combustion part;

[0031] When the combustion part is in the first position, at least a part of the first air inlet part coincides with the ventilation part and is opened, and the second air inlet part is completely staggered from the ventilation part and is closed;

[0032] When the combustion part is in the second position, both the first air inlet part and the second air inlet part at least partially coincide with the ventilation part and are opened.

[0033] The above burner does not need to be provided with a separate control structure such as a valve. By respectively arranging hole-shaped structures on the side where the combustion part and the base are mutually attached, the air inlet structure is opened through the coincidence of the hole-shaped structures, and the air inlet structure is closed through the staggering of the hole-shaped structures, reducing the distance between the air inlet structure and the ventilation part, improving the reliability of the cooperation between the two, and simplifying the structure of the gas passage.

[0034] Optionally, the part of the partition plate facing the air inlet hole bulges downward to form a flow splitting part, and the flow splitting part divides the air inlet hole into a first air inlet part and a second air inlet part.

[0035] The burner divides the air inlet hole into a first air inlet part and a second air inlet part separated from each other by the flow divider, thereby simplifying the structure of the air inlet structure and making the manufacturing of the burner part more convenient. In addition, the distance between the first air inlet part and the second air inlet part can be reduced, so that the first air inlet part and the second air inlet part are connected simultaneously through the same air hole, thereby simplifying the structure of the base.

[0036] Optionally, the base is provided with a first guide structure, and the combustion part is provided with a second guide structure, and the second guide structure is slidably matched with the first guide structure so that the combustion part slides along the base.

[0037] Optionally, the first guide structure is provided with a vent, and the second guide structure is provided with an air intake structure, so that the processing is more convenient, and the matching accuracy between the air intake structure and the vent can be further improved through the precise matching between the first guide structure and the second guide structure.

[0038] Optionally, a first protrusion is provided on one side of the combustion part facing the base, and the first protrusion stops at the base to limit the sliding stroke of the combustion part, thereby preventing the combustion part from slipping along the base and ensuring the safety of the burner.

[0039] Optionally, the first fire hole area is arranged at a side of the combustion portion away from the center of the burner, and the second fire hole area is arranged at one end of the combustion portion along the arrangement direction.

[0040] In the above-mentioned burner, when the burning part is located at the first position, due to the small size of the burner, the inner flame of the burning part is easy to interfere with the flame of the burning center, affecting the stability of the flame. By arranging the first fire hole area on the side of the burning part away from the center of the burner, only the outer side of the burning part has a flame, and no flame is present in other parts, thereby ensuring the stability of the flame combustion. When the burning part is located at the second position, there will be a gap between adjacent burning parts. By arranging the second fire hole area at one end of the burning part along the arrangement direction, there will be a flame in the gap between adjacent burning parts, thereby increasing the flame area and improving the heating efficiency of the burner for large-sized cooking utensils.

[0041] In addition, the second fire hole area is arranged at one end of the combustion part along the arrangement direction, which can also play a role in fire transfer between two adjacent combustion parts, thereby reducing the number of fire transfer grooves arranged on the combustion part.

[0042] Optionally, the second fire hole area is arranged on a side of the combustion portion facing the center of the burner.

[0043] In the above burner, when the combustion part is in the second position, the size of the burner is larger, and the inner flame of the combustion part will not interfere with the flame of the combustion center part. Therefore, the second flame hole area can be arranged on the side where the combustion part faces the center of the burner, so as to form a larger flame area, further improving the heating efficiency of the burner for large-sized cooking utensils.

[0044] Optionally, a plurality of the combustion parts are arranged in sequence around the center of the burner, and the combustion parts can slide in a direction close to or away from the center of the burner.

[0045] The above burner has a fixed shape and adjustable size, so that the burner can be suitable for cooking utensils with different diameters, and can make the combustion part have a simple sliding track, thus simplifying the operation of the user.

[0046] Optionally, a plurality of the combustion parts are arranged in sequence around the center of the burner in a ring shape, and the combustion parts can slide along the radial direction of the burner.

[0047] Since most cooking utensils are set to be circular, the above burner has a circular overall appearance, so that the burner can better match the cooking utensils.

[0048] The second aspect of the present application provides a gas stove, which includes the burner of any gas stove provided by the present application.

[0049] It should be understood that the above general description and the following detailed description are only exemplary and cannot limit the present application.

[0086] The accompanying drawings here are incorporated into the specification and form a part of this specification, showing embodiments consistent with this application, and are used together with the specification to explain the principles of this application. Detailed implementation manners

[0087] In order to make the objectives, technical solutions and advantages of this application clearer and more understandable, the following further details this application in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0088] In the description of this application, unless otherwise clearly specified and limited, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance; unless otherwise specified or stated, the term "plurality" means two or more; the terms "connection", "fixation", etc. should all be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in this invention can be understood according to specific circumstances.

[0089] In the description of this specification, it should be understood that the orientation terms such as "upper" and "lower" described in the embodiments of this application are described from the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. In addition, in the context, it should also be understood that when it is mentioned that one element is connected "above" or "below" another element, it can not only be directly connected "above" or "below" another element, but also be indirectly connected "above" or "below" another element through an intermediate element.

[0090] As Figures 1-8 shown, the embodiments of this application provide a burner for a gas stove, which includes a plurality (including two or more) slidable combustion sections 2. The plurality of combustion sections 2 are arranged in sequence to jointly form the burner. The combustion section 2 is provided with a fire outlet hole 20. The fire outlet hole 20 can be arranged on the side wall of the combustion section 2. The flame of the burner can be ejected from the fire outlet hole 20 and heat the cooking utensil through the flame. When the combustion section 2 slides, the fire outlet hole 20 slides together with the combustion section 2, thereby adjusting the flame combustion area of the burner so that the burner can be applicable to cooking utensils with different diameters.

[0091] Among them, the burner may further include a combustion center portion 3 which forms the center of the burner and heats the central portion of the cooking appliance; a plurality of combustion portions 2 are arranged in sequence around the center of the burner to form various shapes, such as any suitable shape like a circle, a square or an ellipse, so that the shape of the burner can adapt to the shape of the cooking appliance; the sliding direction of the combustion portion 2 can also be any suitable direction to facilitate the user to flexibly adjust the shape and size of the burner according to the usage requirements.

[0092] In some embodiments, a plurality of combustion portions 2 are arranged in sequence around the center of the burner, and the combustion portions 2 can slide in a direction closer to or farther from the center of the burner, so that the burner has a fixed shape and an adjustable size, thereby enabling the burner to be applicable to cooking appliances with different diameters and enabling the combustion portions 2 to have a simple sliding track, thus simplifying the operation of the user.

[0093] In one embodiment, since most cooking appliances are set to be circular, a plurality of combustion portions 2 can be arranged in a ring shape in sequence around the center of the burner, and the combustion portions 2 can slide along the radial direction of the burner, so that the burner has a circular overall appearance, thereby enabling the burner to better match the cooking appliance.

[0094] Furthermore, the burner provided in the embodiment of the present application may include a base 1 and a combustion portion 2. The base 1 is used to connect to the cooking top of the gas stove, and the combustion portion 2 is slidably connected to the base 1, so that the burner has high integrity and versatility. That is to say, the base 1 can adapt to the cooking top of the gas stove and be fixed to the cooking top of the gas stove. A plurality of combustion portions 2 are arranged in sequence along the base 1 and can slide along the base 1 without changing the original shape of the cooking top of the gas stove. A gas mixing chamber is provided inside the base 1. The base 1 may include a base body 1a and a base cover 1b, and the base cover 1b covers the opening of the base body 1a; the combustion portion 2 includes an air storage chamber 22, and the fire outlet holes 20 communicate with the air storage chamber 22. The combustion portion 2 may include a combustion portion body 2c and a combustion portion cover 2d, and the combustion portion cover 2d covers the opening of the combustion portion body 2c.

[0095] It can be understood that the base 1 and the combustion portion 2 may also be set as a whole, that is to say, the base 1 and the combustion portion 2 correspond to each other and are fixedly connected, and the base 1 and the combustion portion 2 slide together. For example, a sliding track is provided on the cooking top of the gas stove, and the base 1 is slidably engaged with the sliding track, and the combustion portion 2 and the base 1 slide along the sliding track together.

[0096] In one embodiment, the base 1 is provided with a first guiding structure 12, and the combustion part 2 is provided with a second guiding structure 26. The second guiding structure 26 is in sliding fit with the first guiding structure 12 so that the combustion part 2 slides along the base 1. By providing the first guiding structure 12 and the second guiding structure 26, the sliding fit accuracy between the base 1 and the combustion part 2 is improved, thereby making the sliding operation of the combustion part 2 smoother. The first guiding structure 12 can be arranged on the base cover 1b, and the second guiding structure 26 can be arranged on the combustion part cover 2d to further improve the manufacturing accuracy of the guiding structure and ensure the sliding fit accuracy between the base 1 and the combustion part 2.

[0097] Specifically, among the first guiding structure 12 and the second guiding structure 26, one of them can be set as a convex block and the other can be set as a groove. The extending direction of the convex block and the groove should be adapted to the sliding direction of the combustion part 2. For example, when the combustion part 2 slides along the radial direction of the burner, the convex block and the groove should extend along the radial direction of the burner. At least one second guiding structure 26 can be arranged on the combustion part 2. When the number of the second guiding structures 26 arranged on the combustion part 2 is one, the second guiding structure 26 can be arranged at the central part of the combustion part 2. When the number of the second guiding structures 26 arranged on the combustion part 2 is multiple, the multiple second guiding structures 26 are arranged at intervals along the combustion part 2 in sequence.

[0098] Furthermore, a first protrusion 27 (see Figure 6 ) is provided on the side of the combustion part 2 facing the base 1. The first protrusion 27 abuts against the base 1 to limit the sliding stroke of the combustion part 2, prevent the combustion part 2 from slipping off the base 1, and ensure the safe use of the burner. Among them, the first protrusion 27 can be only arranged on the side of the combustion part 2 close to the center of the burner, so as to only limit the sliding stroke of the combustion part 2 away from the center of the burner. When the combustion part 2 slides towards the center of the burner, adjacent combustion parts 2 abut against each other, thereby automatically limiting the sliding stroke of the combustion part 2. Of course, the first protrusion 27 can also be arranged on the side of the combustion part 2 away from the center of the burner.

[0099] Furthermore, a second protrusion 28 (see Figure 6 and Figure 7), the second protrusion 28 is arranged on the side of the combustion part 2 close to the center of the burner, and is distributed at both ends of the combustion part 2, that is, the second protrusion 28 is arranged at the ends of two adjacent combustion parts 2 that are adjacent to each other. The second protrusion 28 is arranged to guide the external airflow, and an air circulation channel is formed between two adjacent second protrusions 28, so that the air outside the combustion part 2 (the side away from the center of the burner) flows along the second protrusion 28 to the inside of the combustion part 2 (the side facing the center of the burner), stabilizing the supply of air inside the combustion part 2, so that the flame inside the combustion part 2 or the flame of the combustion center part 3 can be fully burned, and the influence of the pressure difference during combustion is prevented, resulting in incomplete combustion.

[0100] Further, see Figures 2-7 The combustion portion 2 includes a first fire hole area 2a and a second fire hole area 2b, and the fire holes 20 are arranged in the first fire hole area 2a and the second fire hole area 2b. That is to say, the first fire hole area 2a and the second fire hole area 2b are both provided with fire holes 20. The flame state of the fire holes 20 is reasonably adjusted according to the size of the burner, so that the flame area of ​​the burner can adapt to the diameter of the cooking utensil, thereby further improving the cooking efficiency.

[0101] In the sliding stroke of the combustion part 2, the combustion part 2 has a first position and a second position; when the combustion part 2 is located at the first position (see Figure 2 ), the first fire hole area 2a has flames, and the second fire hole area 2b has no flames, so that the burner has fewer flame areas and is suitable for heating cooking utensils with small diameters; when the burning part 2 is in the second position (see Figure 3 ), both the first fire hole area 2a and the second fire hole area 2b have flames, so that the burner has more flame areas and is suitable for heating cooking utensils with large diameters.

[0102] In one embodiment, the first fire hole area 2a is arranged on the side of the combustion section 2 away from the center of the burner, that is, the first fire hole area 2a is arranged on the outer wall of the combustion section 2; the second fire hole area 2b is arranged at one end of the combustion section 2 along the arrangement direction, that is, the second fire hole area 2b is arranged at one end of the combustion section 2, and the second fire hole area 2b is not arranged at the other end, so as to avoid interference between the flames of the two adjacent combustion sections 2 in the second fire hole area 2b.

[0103] When the burning part 2 is in the first position, due to the small size of the burner, the inner flame of the burning part 2 is easy to interfere with the flame of the burning center part 3, affecting the stability of the flame. By setting the first fire hole area 2a on the side of the burning part 2 away from the center of the burner, the burning part 2 only has flames on the outside, and no flames in other parts, thereby ensuring the stability of flame combustion. When the burning part 2 is in the second position, there will be a gap between adjacent burning parts 2. By setting the second fire hole area 2b at one end of the burning part 2 along the arrangement direction, there will be flames in the gap between adjacent burning parts 2, thereby increasing the flame area and improving the heating efficiency of the burner for large-sized cooking utensils. In addition, setting the second fire hole area 2b at one end of the burning part 2 along the arrangement direction can also play a role in fire transmission between two adjacent burning parts 2, reducing the number of fire transmission grooves 29 set on the burning part 2, that is, only one of the burning parts 2 needs to be provided with a fire transmission groove 29; of course, fire transmission grooves 29 can also be provided on each burning part 2.

[0104] It can be understood that when the combustion part 2 is located at the second position, the burner size is larger, and the inner flame of the combustion part 2 will not interfere with the flame of the combustion center part 3. Therefore, the second fire hole area 2b can also be set on the side of the combustion part 2 facing the center of the burner (see Figure 4 ), resulting in a larger flame area, further improving the burner's heating efficiency for large-sized cooking utensils.

[0105] In one embodiment, a partition 24 is provided in the gas chamber 22, and the partition 24 divides the gas chamber 22 into a first chamber 220 and a second chamber 222, so that the first chamber 220 and the second chamber 222 are not connected to each other, the second chamber 222 is close to the center of the burner, and the first chamber 220 is far from the center of the burner. By controlling the gas supply to the first chamber 220 and the second chamber 222, the flame of the corresponding fire hole 20 can be controlled. The first fire hole area 2a is located on the side wall of the first chamber 220, and the fire holes 20 provided in the first fire hole area 2a are connected to the first chamber 220. When gas is introduced into the first chamber 220, there is a flame in the first fire hole area 2a; the second fire hole area 2b is located on the side wall of the second chamber 222, and the fire holes 20 provided in the second fire hole area 2b are connected to the second chamber 222. When gas is introduced into the second chamber 222, there is a flame in the second fire hole area 2b.

[0106] Specifically, see Figure 7, the partition plate 24 can be set to be approximately L-shaped. That is to say, the partition plate 24 includes a first section 240 and a second section 242 that are connected to each other. The first section 240 extends along the arrangement direction of the combustion part 2, and the second section 242 extends from the inner side to the outer side of the combustion part 2, so as to divide the air-containing cavity 22 into an L-shaped second cavity 222 and a linear first cavity 220, making the inner side wall at one end of the air-containing cavity 22 completely located in the first cavity 220 and forming a second flame hole area 2b.

[0107] Furthermore, the air-containing cavity 22 is provided with an air intake structure 25. The air intake structure 25 includes a first air intake part 250 and a second air intake part 252 that are separated from each other; the first air intake part 250 communicates with the first cavity 220. When the first air intake part 250 is opened, gas can be introduced into the first cavity 220. When the first air intake part 250 is closed, gas cannot be introduced into the first cavity 220; the second air intake part 252 communicates with the second cavity 222. When the second air intake part 252 is opened, gas can be introduced into the second cavity 222. When the second air intake part 252 is closed, gas cannot be introduced into the second cavity 222. When the combustion part 2 is in the first position, the first air intake part 250 is opened and the second air intake part 252 is closed, so that gas is introduced into the first cavity 220 and gas cannot be introduced into the second cavity 222, so that there is a flame in the first flame hole area 2a and no flame in the second flame hole area 2b; when the combustion part 2 is in the second position, both the first air intake part 250 and the second air intake part 252 are opened, so that gas is introduced into both the first cavity 220 and the second cavity 222, so that there are flames in both the first flame hole area 2a and the second flame hole area 2b.

[0108] Furthermore, the base 1 is provided with a ventilation part 10. Gas is supplied to the air intake structure 25 through the ventilation part 10, and the opening and closing of the air intake structure 25 are controlled through the ventilation part 10. The structure is simple and the control is convenient. As the combustion part 2 slides, the first air intake part 250 and the second air intake part 252 can communicate with the ventilation part 10 to be opened, or isolate the ventilation part 10 to be closed. When the combustion part 2 is in the first position, the first air intake part 250 communicates with the ventilation part 10 and is opened, and the second air intake part 252 isolates the ventilation part 10 and is closed; when the combustion part 2 is in the second position, both the first air intake part 250 and the second air intake part 252 communicate with the ventilation part 10 and are opened.

[0109] Specifically, the ventilation part 10 should correspond one-to-one with the combustion part 2. That is to say, at least one ventilation part 10 should be provided on the base 1 corresponding to each combustion part 2. Among them, the number of ventilation parts 10 provided corresponding to the same combustion part 2 is one or two; when the number of ventilation parts 10 is one, the first air intake part 250 and the second air intake part 252 are communicated through the same ventilation part 10; when the number of ventilation parts 10 is two, the two ventilation parts 10 communicate with the first air intake part 250 and the second air intake part 252 respectively.

[0110] In one embodiment, the intake structure 25 is an intake hole, and the intake hole is disposed on the side of the combustion part 2 facing the base 1; the ventilation part 10 is a ventilation hole, and the ventilation hole is disposed on the side of the base 1 facing the combustion part 2; that is to say, the intake structure 25 and the ventilation part 10 are respectively disposed on the side where the combustion part 2 and the base 1 are in contact with each other, thereby reducing the distance between the intake structure 25 and the ventilation part 10 and improving the reliability of the cooperation between the two. When the combustion part 2 is in the first position, at least a part of the first intake part 250 coincides with the ventilation part 10 and is opened, and the second intake part 252 is completely staggered from the ventilation part 10 and is closed; when the combustion part 2 is in the second position, at least a part of both the first intake part 250 and the second intake part 252 coincides with the ventilation part 10 and is opened.

[0111] In another embodiment, a part of the partition 24 facing the intake hole bulges downward to form a flow dividing part 244. The flow dividing part 244 divides the intake hole into a first intake part 250 and a second intake part 252. That is to say, the intake structure 25 includes an intake hole, and the intake hole is divided into a first intake part 250 and a second intake part 252 that are separated from each other by the flow dividing part 244, simplifying the structure of the intake structure 25 and making the processing and manufacturing of the combustion part 2 more convenient. In addition, the distance between the first intake part 250 and the second intake part 252 can also be reduced, so that the same ventilation hole can communicate with the first intake part 250 and the second intake part 252 at the same time, simplifying the structure of the base 1.

[0112] In one embodiment, when the base 1 is provided with a first guiding structure 12 and the combustion part 2 is provided with a second guiding structure 26, the ventilation part 10 can be disposed on the first guiding structure 12, and the intake structure 25 can be disposed on the second guiding structure 26, making the processing more convenient and improving the matching accuracy between the intake structure 25 and the ventilation part 10.

[0113] In addition, the embodiment of the present application also provides a gas stove, which includes the burner of any gas stove provided by the embodiment of the present application.

[0114] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
