[0042] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0043] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0044] For ease of description, spatial relative terms may be used herein to describe the relative position or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the burner in use or operation other than the orientation depicted in the figure. For example, if the burner in the figure undergoes a position flip or a change in posture or a change in motion state, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." can include both upper and lower orientations. The burner can be oriented otherwise (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0045] See also Figure 1 In a first aspect, an embodiment of the present application provides a stove 1000, which is a basic device for cooking food in a kitchen. The stove 1000 heats food by burning fuel to generate heat.

[0046] The stove 1000 includes a stove shell 200 and a burner 100. The stove shell 200 is the external structure of the stove 1000. At least part of the burner 100 is installed in the stove shell 200. The stove shell 200 can provide support and protection for the burner 100 and other internal structures. The stove shell 200 is usually made of high-temperature resistant and easy-to-clean materials such as stainless steel, tempered glass or ceramics, which helps to isolate heat, prevent users from directly contacting high-temperature components, and reduce the risk of burns. The burner 100 generates flames by mixing fuel (such as natural gas, liquefied petroleum gas, etc.) with air and igniting it through an ignition device.

[0047] like Figure 2 , Figure 3 and Figure 4As shown, the stove shell 200 includes a panel 201, a bottom shell 203, and a water receiving tray 202 arranged on the panel 201. The panel 201 and the bottom shell 203 enclose and define a receiving cavity 200b. The receiving cavity 200b provides an installation space for the burner 100, which can keep the exterior of the stove 1000 neat and beautiful. The bottom shell 203 is folded and provided with a skirt 2031. The panel 201 abuts against the skirt 2031. The skirt 2031 provides support for the panel 201, making the stove shell 200 more stable as a whole. The panel 201 is located at the top of the stove 1000, and the whole is smooth and easy to clean. The bottom shell 203 is located at the bottom of the stove 1000. The bottom shell 203 can be placed on the stove, providing a solid support foundation for the cooker, ensuring the stability of the entire stove 1000. The water receiving tray 202 can provide additional support for the cooker, enhancing the stability of the overall structure of the stove 1000.

[0048] Please continue reading Figure 4 , wherein the panel 201 may be a square panel 201, which can more effectively utilize the kitchen space to adapt to cookers of different shapes and sizes. The water tray 202 may be a square water tray 202 adapted to the square panel 201, which improves the harmonious appearance design of the stove shell 200. The stove shell 200 also has a stove eye 200a that passes through the panel 201 and the water tray 202. The stove eye 200a may be a circular through hole. The burner 100 is fixed in the stove eye 200a. When the burner 100 is ignited, the flame can transfer heat to the cooker through the stove eye 200a. Of course, in other embodiments, the shape of the panel 201 and the water tray 202 can also be configured to be circular, and the shape of the stove eye 200a can also be configured to be a square hole, etc.

[0049] Second, see Figure 1 and Figure 2 The present application also provides a burner 100 for the above-mentioned stove 1000. The burner 100 includes a gas distribution plate assembly 20 and a fire cover assembly 30. The fire cover assembly 30 is covered on the gas distribution plate assembly 20. The gas distribution plate assembly 20 includes a plurality of gas distribution parts 21. Each gas distribution part 21 has a gas mixing cavity 21a (such as Fig. 9 ), the gas and air can be pre-mixed in the gas mixing chamber 21a, and the fully mixed gas and air can improve the combustion efficiency. The fire cover assembly 30 includes a multi-petal fire cover 31, which is also called a flame distributor. Multiple fire covers 31 are arranged in a one-to-one correspondence with multiple gas distributors 21. The material of the fire cover 31 is mostly copper or cast iron, which has the characteristics of high temperature resistance and corrosion resistance. Each fire cover 31 has a fire hole 31a, which is connected to the corresponding gas mixing chamber 21a. The fire hole 31a is where the gas and air mixture is ejected and ignited, and can form a flame. The flame contacts the cooker through the fire hole 31a.

[0050] Among them, the gas distribution plate assembly 20 can be annular as a whole, and the annular gas distribution plate assembly 20 can be evenly divided into a plurality of gas distribution parts 21. Similarly, the fire cover assembly 30 can be annular as a whole, and the annular fire cover assembly 30 can be evenly divided into a plurality of petal fire covers 31. The number of gas distribution parts 21 and fire covers 31 is equal, which can be 5, 7 or 9. In other embodiments, it can also be other numbers, and the present application does not limit this.

[0051] like Figure 5 As shown, it can be understood that the fire hole 31a includes a plurality of main fire holes 31a1 and a plurality of auxiliary fire holes 31a2. The plurality of main fire holes 31a1 are arranged at intervals on the circumference of the fire cover 31. When burning, the plurality of main fire holes 31a1 on the multi-petal fire cover 31 define a ring-shaped pot-wrapping fire shape, and the plurality of main fire holes 31a1 can heat the bottom of the cooker uniformly from the circumference. The auxiliary fire holes 31a2 are arranged along the radial direction of the fire cover assembly 30. The auxiliary fire holes 31a2 can provide additional flames to assist the main fire holes 31a1 in burning, so that the heating efficiency of the bottom of the cooker is improved.

[0052] like Figure 2 and Figure 5 As shown, the burner 100 also includes a drive assembly 10, which is connected to the plurality of gas distribution parts 21 in a transmission manner, and the plurality of fire covers 31 are connected to the plurality of gas distribution parts 21 in a one-to-one correspondence to form a plurality of opening and closing structures. The drive assembly 10 can drive the plurality of opening and closing structures to move in a direction close to or away from the central axis of the burner 100 to adjust the outer diameter of the fire cover 31 assembly as a whole, thereby adjusting the pot-wrapping fire type of the burner 100. The drive assembly 10 allows the user to dynamically adjust the size of the pot-wrapping fire type according to cooking needs, change the combustion outer diameter of the flame, and thus control the flame coverage range. By changing the flame coverage range, the flame can tightly surround cookers of various sizes, and uniform heating can be achieved whether it is a small stew pot or a large wok. Users can easily adjust the flame coverage range according to cooking needs and the size of the cooker, thereby improving the flexibility and convenience of cooking. By adjusting the flame coverage range, heat waste can be reduced, thermal efficiency can be improved, and a more energy-saving cooking method can be achieved.

[0053] It should be noted that: in the process of adjusting the flame coverage, the mixture ratio of gas and air remains unchanged, so the intensity and temperature of the flame remain constant. Since the mixture ratio of gas and air remains unchanged, the combustion efficiency of the flame remains at the best state, reducing the problem of incomplete combustion caused by adjusting the flame intensity to adapt to the pot type.

[0054] Furthermore, during the activity of the plurality of opening and closing structures, the closed position closest to the central axis of the burner 100 (eg Figure 6 ), and the open position farthest from the central axis of the burner 100 (such as Figure 7). Understandably, when the opening and closing structure is in the closed position, the outer diameter of the fire cover assembly 30 is smaller, that is, the fire type of the pot is smaller, which is suitable for cooking with small pots, such as making soup, boiling noodles, etc. When the opening and closing structure is in the open position, the outer diameter of the fire cover assembly 30 is larger, that is, the fire type of the pot is larger, which is suitable for cooking with large pots, such as stewing meat, steaming buns, etc. By adjusting between the closed position and the open position, precise control of the flame coverage can be achieved to adapt to cookers of different sizes.

[0055] See also Figure 6 and Figure 7 Each fire cover 31 also has an inner fire transfer groove 31b and an outer fire transfer groove 31c. The inner fire transfer groove 31b of the same fire cover 31 is arranged closer to the central axis of the burner 100 than the outer fire transfer groove 31c. The inner fire transfer groove 31b runs through both sides of the circumference of the fire cover 31. The multiple inner fire transfer grooves 31b on all fire covers 31 form an annular inner fire transfer groove 31b. The outer fire transfer groove 31c is arranged in an arc segment. The length of the outer fire transfer groove 31c is shorter than the length of the inner fire transfer groove 31b. The inner fire transfer groove 31b and the outer fire transfer groove 31c both intersect with the auxiliary fire hole 31a2, so that the flame can be smoothly transferred from the auxiliary fire hole 31a2 to the circumference of different radial lengths, forming a continuous flame belt, and achieving uniform heating of the cooker.

[0056] like Figure 6 As shown, in the closed position, the two inner flame transfer grooves 31b of the two adjacent fire covers 31 are arranged opposite to each other along the circumference of the burner 100. The multiple inner flame transfer grooves 31b play a role in circumferential flame transfer in the closed position, and can effectively transfer the flame from the center to the surroundings. In the open position, the inner flame transfer groove 31b of one of the two adjacent fire covers 31 is arranged opposite to the outer flame transfer groove 31c of the other fire cover 31 along the circumference of the burner 100. It can be understood that Figure 7 As shown, in the open position, the two adjacent inner fire transfer grooves 31b are no longer arranged relative to each other, but are designed so that an inner fire transfer groove 31b is opposite to an adjacent outer fire transfer groove 31c, so that the inner fire transfer groove 31b and the outer fire transfer groove 31c cooperate with each other to transfer flames, thereby maintaining the circumferential transfer of flames.

[0057] like Figure 4 , Figure 8 and Fig. 9As shown, in some embodiments, the water receiving tray 202 is provided with an annular protrusion 2021 arranged around the stove eye 200a, and the annular protrusion 2021 is arranged concentrically with the fire cover assembly 30. Each fire cover 31 includes a fire cover portion 311 and a water receiving portion 312 connected to each other. The water receiving portion 312 is located above the water receiving tray 202, and the orthographic projection of the water receiving portion 312 covers the annular protrusion 2021, that is, the outer diameter of the water receiving portion 312 is greater than the diameter of the annular protrusion 2021. When overflow occurs, the liquid overflows from the edge of the cooker. Since the height of the fire cover portion 311 is higher than the water receiving portion 312, the overflowed liquid is first guided to flow to the water receiving portion 312 of the fire cover 31. The water receiving portion 312 has a large area and can collect the liquid flowing out of the cooker. If the liquid exceeds the collection range of the water receiving portion 312, it will continue to flow to the water receiving tray 202. The annular protrusion 2021 protrudes from the water receiving tray 202 to prevent the overflowing liquid from flowing into the stove 1000 through the stove eye 200a, thereby avoiding damage to the internal structure. The liquid is finally collected in the low-lying part of the water receiving tray 202.

[0058] Furthermore, the water receiving portion 312 has a smooth surface. The design of the water receiving portion 312 not only prevents liquid from overflowing, but also reflects more heat radiation to the bottom of the pot, thereby increasing thermal efficiency.

[0059] Please continue reading Fig. 9 It should be noted that the fire cover portion 311 has a step portion 3111 (such as Fig.12 ), the step division 3111 is located at the lower side of the fire cover portion 311, and the shape and size of the step division 3111 and the gas separation portion 21 are adapted, so that the step division 3111 is inserted into the mixing chamber 21a, thereby achieving a sealed fit between the fire cover portion 311 and the gas separation portion 21, and enhancing the stability of the connection, so that the fire cover portion 311 and the mixing chamber 21a have an interference fit, which helps to prevent the mixed gas in the mixing chamber 21a from leaking from the connection between the fire cover portion 311 and the gas separation portion 21, thereby reducing the risk of gas leakage.

[0060] like Figure 7 and Figure 8 As shown, further, the fire cover 311 has an upper surface and an outer inclined surface, the outer inclined surface connects the upper surface and the water receiving portion 312, the upper surface is provided with auxiliary fire holes 31a2, inner fire transfer grooves 31b and outer fire transfer grooves 31c, and the upper surface is inclined upward from the central axis of the fire cover 311 to the direction of the outer circumference of the fire cover 311, which helps to guide the flame in the central area to spread to the periphery. The outer inclined surface is evenly spaced with main fire holes 31a1, and the outer inclined surface is inclined downward from the upper surface toward the water receiving portion 312. Due to the existence of the inclined surface, the flame will extend outward along the inclined surface, which helps to form a ring-shaped pot-wrapping fire type.

[0061] like Figure 2As shown, in some embodiments, the driving assembly 10 includes a driving member 11 and a driven member 12. The driving member 11 can rotate around its own axis. The driving member 11 can be a motor or a manual knob, and the user can control it through simple operations (such as rotating the knob or pressing a button). The driven member 12 is connected to the driving member 11 in a transmission manner. The driven member 12 can be a gear or a lever system. The driven member 12 is connected to the driving member 11 through gears, chains, belts or other mechanical connection methods to ensure the transmission of force, so that it rotates around the central axis of the burner 100 under the drive of the driving member 11, and the driven member 12 is connected to multiple air distribution parts 21 in a transmission manner. The rotation of the driving member 11 is transmitted to the air distribution parts 21 through the driven member 12, thereby driving multiple groups of opening and closing structures. Among them, the driving member 11 drives multiple groups of the above-mentioned opening and closing structures to move in the direction close to or away from the central axis of the burner 100 through the driven member 12. The opening and closing structure includes the main fire hole 31a1 part of the fire cover 31 to adjust the circumferential size of the pot fire type.

[0062] like Figure 4 and Figure 5 As shown, specifically, a valve shaft hole 201a is provided on the panel 201, and the driving member 11 includes an opening and closing adjustment knob 111 and a driving gear 112, and the driving gear 112 is coaxially connected with the opening and closing adjustment knob 111, and the opening and closing adjustment knob 111 and the driving gear 112 rotate around the axial direction of the driving gear 112 itself, that is, when the user twists the opening and closing adjustment knob 111, the driving gear 112 rotates accordingly. The driven member 12 includes a driven gear plate 121, and the driven gear plate 121 is meshed with the driving gear 112, and the rotational motion of the driving gear 112 is converted into the rotation of the driven gear plate 121. And the driven gear plate 121 has an installation cavity 121a; wherein, multiple air distributors 21 can be movably installed in the installation cavity 121a and are movably connected with the driven gear plate 121, that is, the rotation of the driven gear plate 121 is transmitted to the air distributor 21 through a mechanical connection (such as a rocker arm, a connecting rod, etc.), so that the air distributor 21 moves in the installation cavity 121a. When the air distributor 21 moves, it drives the sealed fire cover 31 to move at the same time, thereby realizing the adjustment of the circumferential size of the fire type of the pot.

[0063] like Fig. 9 As shown, further, the driving gear 112 has a boss portion 1121 and a gear portion 1122, the boss portion 1121 is convexly arranged on the gear portion 1122 and is inserted into the valve shaft hole 201a, and the opening and closing adjustment knob 111 is fixedly connected to the boss portion 1121 by a screw, and the user can adjust the pot fire type by rotating the opening and closing adjustment knob 111. An indicator 1111 is provided on the opening and closing adjustment knob 111 to facilitate the user to identify the rotation angle.

[0064] like Fig. 9 and Fig.10As shown, in some embodiments, the driven gear plate 121 includes a plate bottom wall 1211 and a plate side wall 1212. The plate side wall 1212 is arranged around the plate bottom wall 1211 and together with the plate bottom wall 1211, a mounting cavity 121a is constructed. The mounting cavity 121a provides a mounting position for the air distributor 21, which is convenient for assembly and maintenance. The plate bottom wall 1211 constitutes the bottom structure of the driven gear plate 121 and provides bottom support for the air distributor 21. The outer peripheral side of the plate side wall 1212 meshes with the driving gear 112 to ensure effective transmission of power.

[0065] Please continue reading Fig. 9 and Fig.10 The drive assembly 10 also includes a plurality of push-pull members 13, and the plurality of push-pull members 13 are arranged in a one-to-one correspondence with the plurality of air distributors 21. One end of the push-pull member 13 is rotatably connected to the disk side wall 1212, and the other end of the push-pull member 13 is rotatably connected to the air distributor 21. The rotatable connection may be a rotating shaft or a hinge structure. Understandably, the push-pull member 13 may be in the shape of a rod, a plate, or other shapes suitable for transmitting power. The push-pull member 13 provides direct force transmission, making the movement of the air distributor 21 more precise and controllable. The plurality of push-pull members 13 can synchronously adjust the position of each air distributor 21. The movement of the air distributor 21 causes the fire cover 31 to move toward or away from the central axis of the burner 100, thereby changing the coverage of the pot fire type.

[0066] like Fig.10 and Fig.11 As shown, the bottom wall 1211 of the disk has a plurality of nozzle guide grooves 1211a that penetrate the bottom wall 1211 of the disk, and the nozzle guide grooves 1211a are arc-shaped grooves, wherein each gas separation portion 21 is also connected to a nozzle 22, and a first threaded hole is provided at the bottom of the gas separation portion 21, and the nozzle 22 has a first threaded portion 221, and the first threaded portion 221 is inserted into the first threaded hole to achieve a fixed connection between the gas separation portion 21 and the nozzle 22. The nozzle 22 can be movably inserted into the nozzle guide groove 1211a and communicated with the gas mixing chamber 21a. The smooth curve of the nozzle guide groove 1211a can reduce the wear of the nozzle 22 during movement, and the arc-shaped movement helps to reduce friction and pressure points. During the rotation of the driven gear plate 121, the corresponding nozzle 22 is driven to slide in the corresponding nozzle guide groove 1211a through the push-pull member 13 and the gas distributor 21. The nozzle guide groove 1211a can make the nozzle 22 move along a predetermined path, thereby improving the control accuracy. The nozzle guide groove 1211a provided through the bottom wall 1211 of the plate can also reduce the wear of the nozzle 22. The synchronous movement of the nozzle 22 and the gas distributor 21 can be ensured, and the consistency of the gas supply can be maintained.

[0067] Please continue reading Fig.11The nozzle 22 also has a plurality of primary air inlet holes 22a arranged circumferentially around the nozzle 22. The primary air inlet holes 22a are connected to the gas mixing chamber 21a. The primary air inlet holes 22a are used to introduce air from the surrounding environment. The air is mixed with the fuel gas in the gas mixing chamber 21a. Appropriate air supply helps to improve combustion efficiency and reduce unburned fuel gas.

[0068] Furthermore, the arc rotation direction of all nozzle guide grooves 1211a is clockwise or counterclockwise, so that multiple groups of opening and closing structures can open and close in the counterclockwise direction or clockwise direction. The uniform arc rotation direction ensures that all nozzles 22 and air distributors 21 respond to the rotation of the drive assembly 10 in a consistent manner, thereby achieving a coordinated opening and closing action. If the rotation directions of the nozzle guide grooves 1211a are inconsistent, it may cause collisions between adjacent air distributors 21. The uniform rotation direction can avoid this situation and reduce mechanical interference.

[0069] In order to reduce the friction between the bottom of the air dividing portion 21 and the bottom wall of the installation cavity 121a, a small roller or ball bearing can be installed at the bottom of the air dividing portion 21 to reduce direct contact with the bottom wall and reduce friction.

[0070] like Fig.11 and Fig.12 As shown, in some embodiments, the gas separation portion 21 includes a main body portion 211 having a mixing chamber 21a and a connecting portion 212 protruding from the outer peripheral side of the main body portion 211. The main body portion 211 and the connecting portion 212 are an integrated structure, which reduces the connection points, so that the integrated connecting portion 212 and the main body portion 211 can withstand force as a whole, thereby improving the overall structural strength of the gas separation portion 21.

[0071] The connecting section 212 has a first rivet hole 212a, and the top of the disk side wall 1212 has a second rivet hole 1212a; each push-pull member 13 includes a push-pull rod 131 and two rivets 132, one rivet 132 is inserted through one end of the push-pull rod 131 and the first rivet hole 212a, and the other rivet 132 is inserted through the other end of the push-pull rod 131 and the second rivet hole 1212a, providing a very stable mechanical connection for both ends of the push-pull rod 131, which can withstand repeated thermal expansion and contraction and vibration generated during the combustion process. It can be understood that the multiple second rivet holes 1212a are evenly spaced and arranged along the circumference of the disk side wall 1212, and are arranged one-to-one with the multiple first rivet holes 212a.

[0072] Furthermore, the end surface of the connecting section 212 with the first rivet hole 212a and the end surface where the second rivet hole 1212a is located are located at the same horizontal plane, ensuring stable riveting and smooth movement of the push-pull member 13. The riveting point of the push-pull member 13 is more stable when subjected to force, reducing wear and deformation, and can be reused for a long time.

[0073] like Figure 5 and Fig.10 As shown, in some embodiments, the burner 100 includes an ignition needle 50 and a thermocouple 70, and the central positions of the gas distribution plate assembly 20 and the fire cover assembly 30 are penetrated with the above-mentioned ignition needle 50 and thermocouple 70. The ignition needle 50 is used to generate an electric spark to ignite the mixture of gas and air and start the combustion process. The fire cover 31 is provided with an ignition outlet 31d, which is arranged toward the side where the ignition needle 50 is located and is connected to the auxiliary fire hole 31a2. The ignition outlet 31d is used to provide flammable gas (such as fuel gas or pilot gas) directly to the place where the ignition needle 50 generates sparks to promote the ignition process. Thermocouple 70 is a temperature sensor used to monitor the temperature of the burner 100 to ensure that the burner 100 operates within a safe temperature range. Once an abnormal situation is found, such as the flame is extinguished or the temperature is too high, the gas supply is immediately cut off to prevent safety accidents.

[0074] Among them, the ignition outlet hole 31d is designed as a conical hole, and the large hole end of the conical hole is directly opposite to the top of the ignition needle 50. Since the spark contact area between the gas and the ignition needle 50 is increased, the ignition speed is accelerated, rapid ignition is achieved, and the ignition rate is further improved.

[0075] See also Fig.10 and Fig.11 The burner 100 further includes an ignition needle mounting member 40 for mounting an ignition needle 50 and a thermocouple mounting member 60 for mounting a thermocouple 70. The ignition needle mounting member 40 is provided with a first bayonet 40a, and the ignition needle 50 is provided with a first concave platform clamping position 51 adapted to the first bayonet 40a, and the first concave platform clamping position 51 is riveted and fixed in the first bayonet 40a. The thermocouple mounting member 60 is provided with a second bayonet 60a, and the thermocouple 70 is provided with a second concave platform clamping position 71 adapted to the second bayonet 60a, and the second concave platform clamping position 71 is riveted and fixed in the second bayonet 60a. The ignition needle 50 and the thermocouple 70 are respectively firmly mounted on the ignition needle mounting member 40 and the thermocouple mounting member 60.

[0076] Further, the ignition needle mounting member 40 and the thermocouple mounting member 60 are both arranged in the mounting cavity 121a, the ignition needle mounting member 40 is connected to the bottom of one of the gas distribution parts 21; the bottom wall has an ignition needle guide groove 1211b, and the ignition needle 50 can be slidably inserted into the ignition needle guide groove 1211b; the thermocouple mounting member 60 is connected to the bottom of the other gas distribution part 21; and the bottom wall 1211 of the disk has a thermocouple guide groove 1211c, and the thermocouple 70 can be slidably inserted into the thermocouple guide groove 1211c. The ignition needle guide groove 1211b and the thermocouple guide groove 1211c are provided to guide the movement of the ignition needle 50 and the thermocouple 70, and move along their respective predetermined paths. When the gas distribution plate assembly 20 moves, the ignition needle mounting member 40 and the thermocouple mounting member 60 connected at the bottom move accordingly, the ignition needle 50 slides in the ignition needle guide groove 1211b, and the thermocouple 70 slides in the thermocouple guide groove 1211c. The movement of the gas distribution plate assembly 20 can synchronously drive the ignition needle 50 and the thermocouple 70 to slide open and close, so that when adjusting the flame, ignition and temperature monitoring can work together.

[0077] Please continue reading Fig.11 Furthermore, both the ignition needle mounting member 40 and the thermocouple mounting member 60 are of "L"-shaped design, the ignition needle mounting member 40 includes a first vertical portion and a first horizontal portion, the first bayonet 40a is formed in the first vertical portion, and the first vertical portion can be wrapped in the first concave platform position 51, so that the ignition needle mounting member 40 and the ignition needle 50 have a larger contact area. Similarly, the thermocouple mounting member 60 includes a second vertical portion and a second horizontal portion, the second bayonet 60a is formed in the second vertical portion, and the second vertical portion can be wrapped in the second boss position, so that the thermocouple mounting member 60 and the thermocouple 70 have a larger contact area, thereby improving the installation stability and fixing strength of the ignition needle 50 and the thermocouple 70.

[0078] Furthermore, the ignition needle mounting member 40 and the thermocouple mounting member 60 can be formed by sheet metal stamping, which can achieve high material utilization, reduce waste, and help save material costs. The stamping process can ensure high consistency between components, ensuring that the size and shape of each ignition needle mounting member 40 and thermocouple mounting member 60 are very precise.

[0079] Among them, the ignition needle guide groove 1211b and the thermocouple guide groove 1211c are both arc grooves, so that the ignition needle 50 and the thermocouple 70 can move along a smooth arc trajectory. The arc trajectory can provide a smoother movement path and reduce the wear of the ignition needle 50 and the thermocouple 70 during movement.

[0080] The ignition needle guide groove 1211b and the thermocouple guide groove 1211c are centrally symmetrical about the central axis of the burner 100, so the movement paths of the ignition needle 50 and the thermocouple 70 inserted therein will also be symmetrical about the central axis. Since the load and thermal stress on both sides are evenly distributed, and the load and wear conditions on both sides are similar, the centrally symmetrical design helps to improve the durability of the ignition needle 50 and the thermocouple 70.

[0081] It is known that the ignition needle mounting member 40 is connected to an air distribution part 21, and a nozzle 22 is connected to the bottom of the air distribution part 21. The ignition needle guide groove 1211b can be connected to the nozzle guide groove 1211a where the nozzle 22 is located. Similarly, the thermocouple guide groove 1211c can be connected to the nozzle guide groove 1211a where its corresponding nozzle 22 is located, that is, the ignition needle guide groove 1211b and the thermocouple guide groove 1211c are respectively connected to two different nozzle guide grooves 1211a. The connection design simplifies the structure of the burner 100 and reduces the need for additional through grooves.

[0082] like Fig.11 and Fig.12 As shown, specifically, an air distribution portion 21 also includes a first protrusion 213, and the first protrusion 213 is arranged at the bottom of the main body portion 211. The ignition needle mounting component 40 is provided with a first limiting hole 40b adapted to the first protrusion 213. The first protrusion 213 is passed through the first limiting hole 40b, and the upper end surface of the ignition needle mounting component 40 is in contact with the bottom surface of the air distribution portion 21. The ignition needle mounting component 40 is also provided with a first through hole 40c, and a nozzle 22 is inserted into the first through hole 40c. Similarly, the other gas distribution part 21 includes a second protrusion 214, and the second protrusion 214 is arranged at the bottom of the corresponding main body part 211. The thermocouple mounting part 60 is provided with a second limiting hole 60b adapted to the second protrusion 214. The second protrusion 214 is penetrated in the second limiting hole 60b, and the upper end surface of the thermocouple mounting part 60 is in contact with the bottom surface of the corresponding gas distribution part 21. The thermocouple mounting part 60 is also provided with a second through hole 60c, and another nozzle 22 is inserted in the second through hole 60c, so that when the gas distribution part 21 moves, the ignition needle mounting part 40 and the thermocouple mounting part 60 are driven to move together. The movement of the gas distribution plate assembly 20 will automatically adjust the position of the ignition needle 50 and the thermocouple 70 to realize the synchronous adjustment of the ignition position. The thermocouple 70 adjusts its position as the gas distribution part 21 moves, so that the temperature of the flame can be monitored more accurately, providing more accurate temperature feedback for the burner 100.

[0083] Please continue reading Fig.11 and Fig.12In some embodiments, the burner 100 further includes a support member 80 and a first bearing 90. The top of the support member 80 is fixedly connected to the bottom wall 1211 of the disk. The support member 80 provides a stable support for the bottom wall 1211 of the driven gear disk 121, ensuring the stability of the driven gear disk 121. A first connection hole is provided on the side of the support member 80 close to the driven gear disk 121, and a second connection hole is provided on the driven gear disk 121. Flat head screws are inserted into the first connection hole and the second connection hole. The flat head screws can provide a stable mechanical connection between the support member 80 and the driven gear disk 121, ensuring that the support member 80 rotates when the driven gear disk 121 rotates. The inner ring of the first bearing 90 is fixedly connected to the bottom end of the support member 80. The support member 80 is inserted into the inner ring of the first bearing 90, and is concentric with the inner ring of the first bearing 90 and is tightened by interference fit, so that the first bearing 90 accurately supports the support member 80, so that it rotates around the correct axis, providing rotation stability for the support member 80.

[0084] like Figure 4 and Fig.12 As shown, further, the outer ring of the first bearing 90 is used to be fixedly connected to the shell of the stove 1000. The shell of the stove 1000 also includes a sink seat 204, which is fixedly connected to the bottom shell 203 by pan head screws. The sink seat 204 is provided with a sink hole 204a, and the sink hole 204a is concentrically arranged with the outer ring of the first bearing 90. The outer ring of the first bearing 90 is interference fit with the sink seat 204 to prevent the first bearing 90 from moving in the axial direction. The interference fit of the outer ring improves the fixing force of the first bearing 90 on the outer ring, thereby improving the load-bearing capacity of the first bearing 90.

[0085] like Fig.11 and Fig.12 As shown, in some embodiments, the burner 100 further includes a valve assembly 91 and a plurality of flexible gas pipes 92, the valve assembly 91 includes a valve body 911 and a plurality of connection nozzles 912 disposed on the valve body 911 and connected to the valve body 911, the valve body 911 can be fixedly mounted on the bottom shell 203 by a pan head screw, the connection nozzle 912 is disposed on one side of the valve body 911 close to the driven gear plate 121, one end of the plurality of flexible gas pipes 92 is connected and connected to the plurality of nozzles 22 in a one-to-one correspondence, and the other end of the plurality of flexible gas pipes 92 is connected and connected to the plurality of connection nozzles 912 in a one-to-one correspondence, forming a channel for the gas from the valve body 911 to the nozzle 22, ensuring that the gas can be smoothly and stably delivered to the nozzle 22. The flexible gas pipe 92 can adapt to the slight movement or vibration that may occur in the burner 100 during installation and use, and avoid leakage at the connection caused by the rigidity of the pipeline.

[0086] Specifically, the nozzle 22 further has a second threaded portion 222, which is arranged opposite to the first threaded portion 221 in the vertical direction. One end of the flexible gas pipe 92 is threadedly connected to the connection nozzle 912, and the other end is threadedly connected to the second threaded portion 222. The threaded connection can achieve good sealing to prevent gas leakage. The threaded connection allows the flexible gas pipe 92 to be quickly installed and removed, which is convenient for maintenance and replacement of the flexible gas pipe 92.

[0087] In some embodiments, the valve body 911 has an inner ring channel and an outer ring channel, and the inner ring channel and the outer ring channel have independent and different gas flow rates, and the burner 100 also includes a first valve and a second valve that can be independently controlled, the first valve is connected to the inner ring channel, and the second valve is connected to the outer ring channel, and the first valve and the second valve are used to adjust the gas distribution in the inner ring channel and the outer ring channel respectively to adjust the gas flow in their respective channels, so that the flexible gas pipe 92 connected to the inner ring channel and the outer ring channel can transport different amounts of gas according to user needs, thereby adjusting the local flame size of the burner 100 to adapt to various cooking needs.

[0088] Exemplarily, the number of flexible hoses is 7. Understandably, there are also 7 connecting nozzles 912 adapted thereto, of which 4 connecting nozzles 912 are connected to the outer ring channel, and 3 connecting nozzles 912 are connected to the inner ring channel. The 7 flexible hoses are connected to the 7 connecting nozzles 912 one by one, and the 7 nozzles 22 connected thereto are alternately arranged in multiple nozzle guide grooves 1211a along the circumferential direction of the bottom wall 1211 of the disc according to the different inner ring channels and outer ring channels connected thereto, and each has an independent gas mixing chamber 21a. By adjusting the gas volume of the inner and outer ring channels, the user can adjust the local fire type and firepower of the burner 100 according to the recipe requirements, thereby effectively improving the user's usage experience.

[0089] Please continue reading Fig.11 and Fig.12 In some embodiments, the valve assembly 91 further includes a gas regulating knob 913 and a valve stem 915. The driving gear 112 is provided with a central channel 112a that penetrates the gas regulating knob 913 and the opening and closing regulating knob 111, and the valve stem 915 is inserted into the central channel 112a. The gas regulating knob 913 is coaxially arranged with the opening and closing regulating knob 111, and a groove 111a is formed on the upper end surface of the opening and closing regulating knob 111. A portion of the gas regulating knob 913 is accommodated in the groove 111a, and at least a portion of the gas regulating knob 913 is located above the opening and closing regulating knob 111, so as to achieve an integrated visual effect. The gas regulating knob 913, the valve stem 915 and the opening and closing regulating knob 111 are concentrically connected in series, so that the user can turn the opening and closing regulating knob 111 to drive the opening and closing of the opening and closing structure.

[0090] like Fig.12As shown, the valve assembly 91 also includes a second bearing 914, the outer ring of the second bearing 914 is fixedly connected to the driving gear 112, the lower end of the driving gear 112 is provided with a bearing hole 112b, the bearing hole 112b is communicated with the central channel 112a, and the second bearing 914 is arranged in the bearing hole 112b and has an interference fit with the hole wall of the bearing hole 112b. The top end of the valve stem 915 is fixedly connected to the gas regulating knob 913, and the bottom end is movably connected to the valve body 911, ensuring that the valve stem 915 can move freely in the valve body 911, and the movably connected allows the valve stem 915 to make necessary movements when opening and closing the valve without damaging other parts of the valve. The valve stem 915 is penetrated by the inner ring of the second bearing 914 and is fixedly connected to the inner ring of the second bearing 914, ensuring that the rotational movement of the valve stem 915 can be transmitted smoothly and accurately. The second bearing 914 provides the support required for the rotation of the valve stem 915, reduces friction, and ensures the stable movement of the valve stem 915.

[0091] like Fig.12 As shown, in some embodiments, the valve assembly 91 further includes a bearing sleeve 916, which is sleeved on the valve stem 915.
