[0047] The present invention provides the following description with reference to the accompanying drawings to assist in a comprehensive understanding of various embodiments of the present invention as defined by the claims and their equivalents. The description includes various specific details to facilitate understanding, but these details should be regarded as merely exemplary. Thus, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the present invention.

[0048] In the description of the present invention, with regard to the orientation description, for example, the orientation or positional relationship indicated by up, down, front, back, left, right, etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0049] It should be understood that when an element (for example, the first element) is "connected" to another element (for example, the second element), the element can be directly connected to the other element, or there can be an intermediate element (for example, the third element) between the element and the other element.

[0050] An embodiment of the present invention provides a flip - type burner that facilitates the disassembly and assembly of a heat - insulating plate, as Figures 1-3 shown, including a burner body 100 and a heat - insulating plate 700. Support feet 150 are provided at the bottom of the burner body 100, and one or more support feet 150 can be provided. When the burner is flipped to the horizontal use state, the support feet 150 abut against the panel of the cooking stove to stably support the burner body 100 and keep the burner body 100 stable. A support guiding structure 160 is provided on the support feet 150. The support guiding structure 160 is used to support the heat - insulating plate 700, providing a supporting force to keep the heat - insulating plate 700 stable. At the same time, the support guiding structure 160 can guide the heat - insulating plate 700, and the user can insert or extract the heat - insulating plate 700 from below the burner body 100 through the support guiding structure 160. A hanging member 170 is also provided at the bottom of the burner body 100, and a hanging groove 710 adapted to the hanging member 170 is provided on the heat - insulating plate 700. After the heat - insulating plate 700 is inserted below the burner body 100, the hanging member 170 can be hooked into the hanging groove 710.

[0051] When installing the heat insulation plate 700, it is only necessary to insert the heat insulation plate 700 under the burner body 100 through the support guiding structure 160, and the hanging member 170 is hooked in the corresponding hanging groove 710. The hanging member 170 and the support guiding structure 160 jointly support and fix the heat insulation plate 700, then the installation of the heat insulation plate 700 can be completed; when disassembling the heat insulation plate 700, it is only necessary to separate the hanging member 170 from the hanging groove 710, and then draw out the heat insulation plate 700 from under the burner body 100 through the support guiding structure 160, then the disassembly of the heat insulation plate 700 can be completed; therefore, this embodiment omits the process of screwing and unscrewing the screws, facilitating the installation and disassembly of the heat insulation plate 700, and it is also more convenient for users to clean the bottom of the heat insulation plate 700 and / or the burner body 100.

[0052] In some embodiments, the hanging member 170 includes a rod portion and a hooking portion. The upper end of the rod portion is connected to the burner body 100, and the lower end is connected to the hooking portion. The width of the hooking portion is greater than the width of the rod portion. The hanging groove 710 includes a first hanging groove portion 711 and a second hanging groove portion 712 connected to the first hanging groove portion 711. In the insertion direction of the heat insulation plate 700, the first hanging groove portion 711 is located in front of the second hanging groove portion 712. The first hanging groove portion 711 is for the hooking portion to pass through, the width of the second hanging groove portion 712 is greater than the width of the rod portion and less than the width of the hooking portion, and the hooking portion can be hooked under the second hanging groove portion 712.

[0053] When installing the heat insulation plate 700, the hooking portion passes through the first hanging groove portion 711 and moves to the lower side of the heat insulation plate 700. As the heat insulation plate 700 is further inserted, the rod portion moves from the first hanging groove portion 711 to the second hanging groove portion 712, and the hooking portion correspondingly moves to the lower side of the second hanging groove portion 712. Since the width of the second hanging groove portion 712 is less than the width of the hooking portion, the hooking portion cannot pass through the second hanging groove portion 712, thus being hooked under the second hanging groove portion 712. When disassembling the heat insulation plate 700, the rod portion moves from the second hanging groove portion 712 to the first hanging groove portion 711, the hooking portion correspondingly moves to the lower side of the first hanging groove portion 711, and then the hooking portion passes through the second hanging groove portion 712, separating the entire hanging member 170 from the hanging groove 710.

[0054] In this embodiment, the hanging member 170 can be a screw. The rod portion of the screw is the rod portion of the hanging member 170, and the head of the screw is the hooking portion of the hanging member 170. The hanging groove 710 can be in a "T" - shaped structure. The wider part is the first hanging groove portion 711, and the narrower part is the second hanging groove portion 712.

[0055] Furthermore, the heat insulation plate 700 includes a convex platform 720 protruding upward. The hanging groove 710 is arranged on the top surface of the convex platform 720. The setting of the convex platform 720 reduces the distance between the hanging groove 710 and the hanging member 170, such that the hanging member 170 does not need to protrude downward for too long a distance.

[0056] Meanwhile, the first hanging groove portion 711 extends along the insertion direction of the heat insulation plate 700 to the side surface of the boss 720. During the process of inserting the heat insulation plate 700 below the burner body 100, the hooking portion passes through the first hanging groove portion 711 on the side surface of the boss 720. As the heat insulation plate 700 is further inserted, the rod portion moves from the first hanging groove portion 711 to the second hanging groove portion 712. During the process of pulling out the heat insulation plate 700 from below the burner body 100, the hooking portion passes through the first hanging groove portion 711 on the side surface of the boss 720 to realize the separation of the hanging member 170 from the hanging groove 710. Thus, by moving the heat insulation plate 700 along the insertion direction, the hanging member 170 can be hooked in the hanging groove 710, and by moving along the pulling-out direction, the hanging member 170 can be separated from the hanging groove 710, without the need for the heat insulation plate 700 to move vertically to enable the hanging portion to pass through the first hanging groove portion 711, further facilitating the installation and disassembly of the heat insulation plate 700.

[0057] In some embodiments, a plurality of protruding support platforms 730 are provided on the bottom surface of the heat insulation plate 700. When the burner is in a horizontal use state, the protruding support platforms 730 can abut against the panel of the cooker to reduce the stress on the hanging member 170 and extend the service life of the hanging member 170.

[0058] In some embodiments, there are two sets of support feet 150, and the two sets of support feet 150 are respectively located on both sides of the heat insulation plate 700. The support guiding structure 160 is a support guiding groove provided on the relatively inner side surfaces of the support feet 150, and the support guiding groove extends along the insertion direction of the heat insulation plate 700. During the process of inserting the heat insulation plate 700 below the burner body 100 and the process of pulling out the heat insulation plate 700 from below the burner body 100, both sides of the heat insulation plate 700 slide in the support guiding grooves of the two sets of support feet 150 respectively. The support guiding grooves play a role of limiting and guiding the heat insulation plate 700, and the bottom wall of the support guiding groove can support the heat insulation plate 700.

[0059] In some embodiments, as Figure 1 and Figure 4 shown, the support foot 150 includes a support foot main body 151 and a connecting block 152. The connecting block 152 is arranged at the bottom of the support foot main body 151 and is fixedly connected to the support foot main body 151. A support guiding groove is formed between the support foot main body 151 and the connecting block 152. In this embodiment, the support guiding groove is formed by a split structure, saving the process of grooving.

[0060] The support foot main body 151 and the connecting block 152 can be fastened together by fixing members 155 such as screws. As Figure 4 shown, a notch can be provided on the right side of the bottom of the support foot main body 151, and a convex block can be provided on the right side of the top of the connecting block 152. The convex block is inserted into the notch, and a support guiding groove is formed between the top wall of the notch and the top surface of the convex block.

[0061] Further, a protective sleeve 153 is sleeved outside the connecting block 152. The protective sleeve 153 can play an elastic buffering role and can be made of soft materials such as silica gel and rubber. When the burner rotates from the flipped state to the horizontal state, the bottom of the support leg 150 will touch the panel of the cooker, and the protective sleeve 153 can reduce the force on the panel, making it difficult for the support leg 150 to damage the panel of the cooker.

[0062] An embodiment of the present invention also provides another flip - type burner that facilitates the disassembly and assembly of the heat insulation plate. Compared with the above - mentioned embodiment, this embodiment provides another installation method for the heat insulation plate. The heat insulation plate can be inserted below the burner body or withdrawn from below the burner body; two hanging parts are arranged front - to - back along the insertion direction of the heat insulation plate at the bottom of the burner body, and two hanging grooves adapted to the two hanging parts are provided on the heat insulation plate. After the heat insulation plate is inserted below the burner body, the two hanging parts are respectively hooked in the two hanging grooves to achieve the installation of the heat insulation plate. Since the hanging parts are arranged front - to - back along the insertion direction of the heat insulation plate, the two hanging parts can hook the heat insulation plate one in front and the other behind to keep the heat insulation plate stable. When the heat insulation plate is withdrawn from below the burner body, the two hanging parts are respectively disengaged from the two hanging grooves to achieve the disassembly of the heat insulation plate.

[0063] In some embodiments, the hanging part includes a rod part and a hooking part. The upper end of the rod part is connected to the burner body, and the lower end is connected to the hooking part. The width of the hooking part is greater than the width of the rod part. The hanging groove includes a first hanging groove part and a second hanging groove part connected to the first hanging groove part. In the insertion direction of the heat insulation plate, the first hanging groove part is located in front of the second hanging groove part. The first hanging groove part allows the hooking part to pass through, the width of the second hanging groove part is greater than the width of the rod part and less than the width of the hooking part, and the hooking part can be hooked below the second hanging groove part.

[0064] When installing the heat insulation plate, the hooking part passes through the first hanging groove part and moves below the heat insulation plate. As the heat insulation plate is further inserted, the rod part moves from the first hanging groove part to the second hanging groove part, and the hooking part correspondingly moves below the second hanging groove part. Since the width of the second hanging groove part is less than the width of the hooking part, the hooking part cannot pass through the second hanging groove part and thus is hooked below the second hanging groove part. When disassembling the heat insulation plate, the rod part moves from the second hanging groove part to the first hanging groove part, the hooking part correspondingly moves below the first hanging groove part, and the hooking part then passes through the second hanging groove part, separating the entire hanging part from the hanging groove.

[0065] In this embodiment, the hanging part can be a screw. The rod part of the screw is the rod part of the hanging part, and the head of the screw is the hooking part of the hanging part. The hanging groove can be in a "T" - shaped structure, the wider part is the first hanging groove part, and the narrower part is the second hanging groove part.

[0066] Further, the heat insulation disc includes two upwardly protruding bosses. Two hanging grooves are respectively arranged on the top surfaces of the two bosses, and the two bosses are arranged front and back along the insertion direction of the heat insulation disc. The arrangement of the bosses reduces the distance from the hanging groove to the hanging member, so that the hanging member does not need to protrude downward for too long a distance.

[0067] At the same time, the first hanging groove portion extends along the insertion direction of the heat insulation disc to the side surface of the boss, and the height of the boss located on the front side in the insertion direction of the heat insulation disc is less than the height of the boss located on the rear side in the insertion direction of the heat insulation disc.

[0068] During the process of inserting the heat insulation disc under the burner body, the hook portion passes through the first hanging groove portion through the first hanging groove portion on the side surface of the boss. As the heat insulation disc is further inserted, the rod portion moves from the first hanging groove portion to the second hanging groove portion. During the process of withdrawing the heat insulation disc from under the burner body, the hook portion passes through the first hanging groove portion through the first hanging groove portion on the side surface of the boss to realize the separation of the hanging member from the hanging groove. Thus, the heat insulation disc can be moved along the insertion direction to hook the hanging member in the hanging groove, and can be moved along the withdrawal direction to separate the hanging member from the hanging groove, without the need for the heat insulation disc to move vertically to make the hanging portion pass through the first hanging groove portion, which further facilitates the installation and disassembly of the heat insulation disc.

[0069] Since the height of the boss located on the front side in the insertion direction of the heat insulation disc is less than the height of the boss located on the rear side in the insertion direction of the heat insulation disc, during the process of inserting the heat insulation disc under the burner body, the front boss will not interfere with the rear hanging member. Therefore, the hanging member located on the front side in the insertion direction of the heat insulation disc can be hooked in the hanging groove of the boss located on the front side in the insertion direction of the heat insulation disc, and the hanging member located on the rear side in the insertion direction of the heat insulation disc can be hooked in the hanging groove of the boss located on the rear side in the insertion direction of the heat insulation disc, so that the two hanging members are simultaneously hooked in different hanging grooves or simultaneously separated from different hanging grooves.

[0070] An embodiment of the present invention also provides an embodiment. On the basis of the above embodiment, as Figures 5-11 shown, the burner of this embodiment further includes a thermocouple 210, an ignition needle 220 and a cover plate 230. The bottom surface of the burner body 100 is provided with an installation groove 101 and a through installation hole 102, and the top surface of the burner body 100 is provided with a through hole 103 communicating with the installation groove 101. The thermocouple 210 is inserted into the installation hole 102, the ignition needle 220 is inserted into the through hole 103, and a part of the ignition needle 220 is embedded in the installation groove 101. The cover plate 230 is fixed on the burner body 100, the cover plate 230 seals the installation groove 101, and the cover plate 230 is used to limit the thermocouple 210 from disengaging from the installation hole 102.

[0071] When installing the thermocouple 210 and the ignition pin 220 of this embodiment, the thermocouple 210 is passed through the mounting hole 102, and the ignition pin 220 is passed through the through hole 103. A part of the ignition pin 220 is embedded in the mounting groove 101. Then, the cover plate 230 is fixed on the burner body 100. The cover plate 230 covers the mounting groove 101 to prevent the ignition pin 220 from disengaging from the mounting groove 101. At the same time, the cover plate 230 also prevents the thermocouple 210 from disengaging from the mounting hole 102, thus completing the installation of the thermocouple 210 and the ignition pin 220. The installation structure is simple and more convenient to assemble. Workers can quickly carry out the installation operation, improving the production efficiency.

[0072] In some embodiments, the thermocouple 210 includes a main rod 211 and a convex ring 212 provided on the outer side of the main rod 211. The outer diameter of the convex ring 212 is larger than the outer diameter of the main rod 211. The mounting hole 102 includes an opening portion 104 at its bottom end with an enlarged aperture, that is, the aperture of the opening portion 104 is larger than the aperture of the upper end of the mounting hole 102. The main rod 211 is passed through the mounting hole 102, and the convex ring 212 is located in the opening portion 104. The cover plate 230 is provided with a notch 231. The width of the notch 231 is smaller than the outer diameter of the convex ring 212 and larger than the outer diameter of the main rod 211. The lower end of the main rod 211 passes through the notch 231, and the convex ring 212 cannot pass through the notch 231. The cover plate 230 can support the convex ring 212 from the bottom to prevent the thermocouple 210 from disengaging from the mounting hole 102. At the same time, the top wall of the opening portion 104 restricts the upward movement of the convex ring 212, so that the thermocouple 210 can be stably installed.

[0073] In some embodiments, the cover plate 230 is detachably installed on the burner body 100, which is convenient for disassembly and installation. Specifically, the cover plate 230 can be fastened to the burner body 100 by screws 232.

[0074] In some embodiments, the ignition pin 220 includes a vertical rod portion 221 and a horizontal rod portion 222 connected to the vertical rod portion 221. The vertical rod portion 221 extends in the vertical direction, and the horizontal rod portion 222 extends in the horizontal direction. The ignition pin 220 has an overall structure similar to an "L" shape. The vertical rod portion 221 is passed through the through hole 103, and one end of the horizontal rod portion 222 close to the vertical rod portion 221 is embedded in the mounting groove 101. The cover plate 230 can support the horizontal rod portion 222 from the bottom to prevent the ignition pin 220 from disengaging from the mounting groove 101.

[0075] Furthermore, an opening can be formed on the side surface of the mounting groove 103, and the horizontal rod portion 222 can extend out from the opening on the side surface of the mounting groove 103, leaving space for the horizontal rod portion 222 and reducing the length of the mounting groove 103.

[0076] In some embodiments, the burner body 100 includes an inner ring burner head 111, an outer ring burner head 112 disposed outside the inner ring burner head 111, and a bump 113. The inner ring burner head 111 has an inner ring gas mixing groove, and an inner ring fire cap is covered thereon. The outer ring burner head 112 has an outer ring gas mixing groove, and an outer ring fire cap is covered thereon. The bump 113 is disposed on the outer side surface of the inner ring burner head 111 or the inner side surface of the outer ring burner head 112. The mounting groove 103 and the mounting hole 101 are disposed on the bottom surface of the bump 113, and the through hole 102 is disposed on the top surface of the bump 113. The cover plate 230 is fixed to the bottom surface of the bump 113.

[0077] In this embodiment, a bump 113 is added on the basis of the existing burner head. The bump 113 provides a mounting position for the thermocouple 210 and the ignition pin 220, and the thermocouple 210 and the ignition pin 220 can be located between the outer ring fire and the inner ring fire. Among them, the bump 113 can be integrally formed with the inner ring burner head 111 or the outer ring burner head 112. The inner ring burner head 111 and the outer ring burner head 112 are connected to each other.

[0078] In some embodiments, as Figure 5 , Figure 10 and Figure 11 shown, the burner of this embodiment further includes a burner rack 300. The burner body 100 further includes a burner head. The bottom of the burner rack 300 is provided with a plurality of pins 310, and the burner head is provided with a plurality of jacks 105 adapted to the pins 310. The burner rack 300 can be detachably placed on the burner head, that is, the burner rack 300 can be placed on the burner head or removed from the burner head. After removing the burner rack 300, it is convenient to clean the burner rack 300 and the burner head. When the burner rack 300 is placed on the burner head, the pins 310 of the burner rack 300 are inserted into the jacks 105, and the burner rack 300 is positioned through the cooperation of the jacks 105 and the pins 310, restricting the lateral movement of the burner rack 300 relative to the burner head, so as to stably support the cookware thereon. In addition, when the burner of this embodiment is a flip-type burner, the burner rack 300 is not easily dropped from the burner head during the flipping process of the burner.

[0079] Further, the burner head may include an inner ring burner head and an outer ring burner head disposed outside the inner ring burner head. The outer ring burner head includes an outer ring wall 106 and a ring plate 107 located outside the outer ring wall 106. The outer ring wall 106 can protrude vertically upward, and it forms the outer side surface of the outer ring gas mixing groove. When the outer ring fire cap 122 is placed on the outer ring burner head, the outer ring wall 106 is used to support the outer ring fire cap 122, and the jack 105 is disposed on the ring plate 107. This structure does not interfere with the outer ring fire cap 122.

[0080] Furthermore, the burner body 100 further includes an inner ring fire cap 121, and the inner ring fire cap 121 is covered on the inner ring burner head.

[0081] In some embodiments, the stove rack 300 includes a plurality of support plates 320 for supporting the pots, and the pins 310 and the support plates 320 are integrally formed, which facilitates the installation of the pins 310 and simplifies the molding process of the pins 310 .

[0082] The embodiment of the present invention also provides another burner, based on the above embodiment, such as Figures 12-16 As shown, the burner of this embodiment further includes a furnace rack 300, an adapter assembly 400 and an air intake assembly 500. The furnace rack 300 can be designed in the shape of an energy-gathering disk, which can be used for windproof and energy gathering. The furnace rack 300 is arranged on the burner body 100. Specifically, the furnace rack 300 can be fixed on the burner body 100, or can be integrally formed with the burner body 100, or can be placed on the burner body 100, so that the furnace rack 300 can be removed from the burner body 100 or placed on the burner body 100 at any time. The burner body 100 includes an air intake pipe 130 located at the bottom thereof, and the gas and primary air enter the burner body 100 through the air intake pipe 130. The adapter assembly 400 is fixed to the bottom of the burner body 100 and is rotatably connected to the air intake assembly 500. The air intake assembly 500 is used to be fixed on the stove body. When the adapter assembly 400 rotates relative to the air intake assembly 500, the burner body 100 can rotate relative to the stove body. The burner body 100 can be rotated to Figure 12 and Figure 13 In normal use, the burner body 100 can also be rotated to Figure 14 and Figure 15 The flipped state shown in the figure makes it convenient for the user to clean the panel of the cooker.

[0083] The adapter assembly 400 includes an ejector tube 410 and a side wall 420. The ejector tube 410 is a venturi tube for accelerating the flow of gas. The gas outlet end of the ejector tube 410 is connected to the gas inlet pipe 130. The gas inlet assembly 500 includes a nozzle 510 and a support plate 530. The side wall 420 is rotatably connected to the support plate 530. When the side wall 420 rotates relative to the support plate 530, the entire burner body 100 can rotate relative to the gas inlet assembly 500. When the burner body 100 rotates to a horizontal state relative to the gas inlet assembly 500, the nozzle 510 is concentrically connected to the gas inlet end of the ejector tube 410, and the nozzle 510 sprays gas to the ejector tube 410. Under the action of the airflow, the primary air and the gas enter the ejector tube 410 together, and then enter the burner body 100 through the gas inlet pipe 130. When the burner body 100 rotates to a horizontal state relative to the air intake assembly 500 , the height of the rotation axis 401 of the side wall 420 and the support plate 530 is greater than the height of the ejector tube 410 .

[0084] In the existing flip - type burner, the rotation axis is usually at the same height as the ejector pipe. This design in this embodiment is equivalent to raising the rotation axis of the adapter assembly 400 and the intake assembly 500, making the position of the furnace rack 300 higher and farther from the cooktop panel. During the flipping process of the burner body 100, the furnace rack 300 is not easily touched by the cooktop panel, and the burner body 100 can be rotated to a vertical state, which increases the flipping angle of the burner and improves the user experience. At the same time, the traditional intake pipe is separately set as the intake pipe 130 and the ejector pipe 410, and the total length of the two can be greater than the length of the traditional intake pipe, which is equivalent to increasing the distance from the furnace rack 300 to the cooktop panel when the burner body 100 is in a flipped state, making it even less likely for the furnace rack 300 to touch the cooktop panel.

[0085] In some embodiments, such as Figure 14 , Figure 17 and Figure 18 shown, the adapter assembly 400 further includes a connecting plate 430. The ejector pipe 410 is arranged at the bottom of the connecting plate 430. The connecting plate 430 extends upward with a protrusion 431 at the trailing end in the ejecting direction. The ejecting direction refers to the direction in which the ejector pipe 410 ejects gas. Taking Figure 7 as an example, the ejecting direction is biased to the left. Therefore, the trailing end of the connecting plate 430 in the ejecting direction is the right - hand end of the connecting plate 430, and the protrusion 431 can protrude obliquely upward or directly upward. The connecting plate 430 and the protrusion 431 extend downward on both the left and right sides in the ejecting direction to form side walls 420, which makes the side walls 420 in a similar "L" - shaped structure. The rotation axis 401 of the side walls 420 and the support plate 530 is located on the side wall 420 below the protrusion 431, and the height of the rotation axis 401 of the side walls 420 and the support plate 530 is greater than the height of the connecting plate 430.

[0086] This embodiment makes the position of the ejector pipe 410 lower. Correspondingly, the position of the intake pipe 130 connected to the ejector pipe 410 is also lower, and the height of the rotation axis 401 of the adapter assembly 400 and the intake assembly 500 can be greater than the height of the ejector pipe 410. The ejector pipe 410, the side walls 420, and the connecting plate 430 can be integrally formed to facilitate the overall forming of the adapter assembly 400 and strengthen the connection strength between the ejector pipe 410, the side walls 420, and the connecting plate 430.

[0087] Furthermore, as Figure 17 and Figure 19 shown, connection flanges 440 are arranged on the outer sides of both side walls 420. The bottom of the burner body 100 has a connecting column 140 extending downward, and the connecting column 140 is fixedly connected to the connection flanges 440 to fix the adapter assembly 400 to the bottom of the burner body 100.

[0088] In this embodiment, the connection column 140 and the connection flange 440 can be fastened together by screws.

[0089] In some embodiments, Figures 12-16 As shown, the air intake assembly 500 also includes a nozzle seat 520, the nozzle 510 is fixed on the top of the nozzle seat 520, and the support plate 530 is arranged on the top surface of the nozzle seat 520 and extends upward, so that the rotation axis 401 is relatively far away from the top surface of the nozzle seat 520, and the furnace frame 300 is not easy to touch the panel.

[0090] When the adapter assembly 400 includes two side walls 420 , two support plates 530 are also provided, and the two support plates 530 are rotatably connected to the two side walls 420 respectively.

[0091] In some embodiments, the ejector tube 410 may be inserted into the air intake pipe 130 to ensure that the ejector tube 410 and the air intake pipe 130 are accurately docked and gas leakage may be greatly reduced.

[0092] In some embodiments, Figures 16-19 As shown, two air inlet pipes are provided, namely, an outer ring air inlet pipe 132 and an inner ring air inlet pipe 131, and two ejector pipes 410 and two nozzles 510 are provided. The gas outlet ends of the two ejector pipes 410 are respectively connected with the outer ring air inlet pipe 132 and the inner ring air inlet pipe 131. When the burner body 100 is rotated to a horizontal state relative to the air inlet assembly 500, the two nozzles 510 are respectively connected with the air inlet ends of the two ejector pipes 410 concentrically. The mixed gas in the outer ring air inlet pipe 132 is used to form an outer ring fire, and the mixed gas in the inner ring air inlet pipe 131 is used to form an inner ring fire, so that the burner of this embodiment is a double ring fire burner.

[0093] Furthermore, the burner body 100 includes an inner ring burner head 111 and an outer ring burner head 112 arranged around the outer side of the inner ring burner head 111. The inner ring burner head 111 is provided with an inner ring gas mixing chamber, and the outer ring burner head 112 is provided with an outer ring gas mixing chamber. The outer ring air inlet pipe 132 and the inner ring air inlet pipe 131 are respectively connected with the outer ring gas mixing chamber and the inner ring gas mixing chamber to pass the gas into the gas mixing chamber for mixing. At the same time, the outer ring air inlet pipe 132 and the inner ring air inlet pipe 131 are both fixedly connected with the inner ring burner head 111 and the outer ring burner head 112. The inner ring burner head 111 of this embodiment is not fixedly connected with the outer ring burner head 112 by other connection structures, but uses the existing air inlet pipe to connect the inner ring burner head 111 and the outer ring burner head 112, which can simplify the connection structure.

[0094] An embodiment of the present invention further provides a cooker, such as Figure 20 As shown, it includes a stove body and a burner of any of the above embodiments. The specific description of the burner can refer to the above embodiments and will not be repeated here.

[0095] The cooking appliance body includes a panel 610 and a bottom case 620 disposed at the bottom of the panel 610. The burner body 100 is disposed above the panel 610, and the burner body 100 is rotatably connected to the panel 610, so that the burner body 100 can be flipped relative to the panel 610.
