[0059] The following examples illustrate the present invention, but the present invention is not limited to these examples. Modifications to the specific embodiments of the present invention or equivalent replacement of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed by the present invention.

[0060] Example 1

[0061] refer to Figure 1-3 The present embodiment provides a base mechanism, and the base mechanism 1 is applied to an upper air inlet burner, including a base assembly 11, a rotating member 12 and a driver 14. The base assembly 11 has at least two gas channels 110, and a nozzle 111 is provided at the outlet of each gas channel 110, so that the base assembly 11 has multiple gas paths. The rotating member 12 is rotatably disposed on the base assembly 11, and is used to connect and drive the ignition divider to rotate, so that the ejector tube 22 on the ignition divider can be connected to any nozzle 111. The present embodiment takes the base assembly 11 having two gas paths as an example. When the ignition divider is driven to rotate by the rotating member 12, the ignition divider can be switched between the first position and the second position, so that the upper air inlet burner can meet a variety of usage states and better meet the user's usage needs.

[0062] In this embodiment, all nozzles 111 are circumferentially spaced apart on the outer side wall of the base assembly 11, the angle between the central axes of adjacent nozzles 111 is an acute angle or an obtuse angle, and the diameters of adjacent nozzles 111 are the same or different. When the diameters of adjacent nozzles 111 are different, the heat loads of the burner at different positions will also be different, and different heat loads can be achieved on the same burner to meet the user's needs for different heat loads in different cooking scenarios.

[0063] Furthermore, an annular groove 112 opening outward is concavely formed on the outer peripheral wall of the base assembly 11, and all the nozzles 111 are circumferentially spaced on the groove wall surface of the annular groove 112 facing the opening. The rotating member 12 is annular in structure, and is rotatably mounted on the annular groove 112. An opening 122 is provided on the rotating member 12, and the opening 122 can be connected with any nozzle 111 when the rotating member 12 rotates. In this way, the upper and lower groove walls of the annular groove 112 are used to limit the upper and lower positions of the rotating member 12, effectively preventing the rotating member 12 from escaping upward or downward during the rotation process, and at the same time ensuring that the central axis of the opening 122 and the central axis of any nozzle 111 are always located on the same horizontal plane, thereby facilitating the reliable connection and communication between the ejector tube on the ignition distributor and any nozzle 111.

[0064] In order to avoid the nozzle 111 interfering with the rotation of the rotating member 12, a recessed portion is provided on the groove wall surface of the annular groove 112 facing the opening, and the recessed portion is arranged corresponding to the outlet of the gas channel 110. The nozzle 111 is installed at the recessed portion and is aligned with the outlet of the corresponding gas channel 110. In addition, in order to prevent the rotating member 12 from radially displacing relative to the base assembly 11, an upper limit portion 1121 extending downward is fixedly provided on the upper groove wall of the annular groove 112. The upper limit portion 1121 is located in the middle of the upper groove wall of the annular groove 112 in the radial direction and abuts against the upper end of the inner side wall of the rotating member 12. A lower limit portion 1122 extending upward is fixedly provided on the lower groove wall of the annular groove 112. The lower limit portion 1122 is located in the middle of the lower groove wall of the annular groove 112 in the radial direction and abuts against the lower end of the inner side wall of the rotating member 12.

[0065] refer to Figure 1-4 In this embodiment, the base assembly 11 includes a base body 1101, an upper fixing ring 1102 and a lower fixing ring 1103. The upper fixing ring 1102 and the lower fixing ring 1103 are respectively mounted on the upper and lower ends of the base body 1101. The upper fixing ring 1102, the lower fixing ring 1103 and the outer peripheral wall of the base body 1101 are enclosed together to form an annular groove 112. In this way, it is convenient for each component to be quickly demoulded and processed, and the yield rate is improved. At the same time, the same or different materials can be used for processing and manufacturing. Two gas channels 110 are provided on the base body 1101, and two recessed parts located before the upper fixing ring 1102 and the lower fixing ring 1103 are provided at intervals in the circumferential direction on the outer peripheral wall of the base body 1101. Nozzles 111 are respectively installed on the two recessed parts. In addition, a plurality of support feet 118 extending downward and arranged at intervals in the circumferential direction are integrally formed at the bottom of the base body 1101 to reliably support the base assembly 11. An upper limit portion 1121 is integrally formed on the upper fixing ring 1102 , and a lower limit portion 1122 is integrally formed on the lower fixing ring 1103 .

[0066] A stop step (not shown) extending outward is integrally formed at the lower end of the outer wall of the base body 1101. The stop step is located below the lower fixing ring 1103 and abuts or connects with the lower fixing ring 1103 to prevent the lower fixing ring 1103 from slipping out downward. In addition, the base assembly 11 also includes an upper cover plate 1104, which is covered on the top of the base body 1101 and the upper fixing ring 1102 and connected to the top of the upper fixing ring 1102 and / or the top of the base body 1101, so as to prevent the upper fixing ring 1102 from slipping out upward through the upper cover plate 1104, and at the same time, it is beneficial to improve the aesthetics of the bottom of the base assembly 11.

[0067] refer to Figure 1-2 and Figure 5A support 123 extending outward is fixedly provided on the outer side wall of the rotating member 12. The support 123 is located above the opening 122 and is used to be detachably connected to the connecting seat 23 on the ignition distributor, so that the ignition distributor 2 can be detachably and reliably connected to the rotating member 12. Further, referring to Figure 1-2 and Figure 6 The base mechanism 1 also includes a swing arm 13, which is arranged outside the base assembly 11. The support 123 of the rotating member 12 is detachably connected to the connecting seat 23 on the igniter 2 through the swing arm 13. In this way, the rotating member 12 and the connecting seat 23 of the igniter 2 are reliably connected together through the swing arm 13, and the distance between the connecting seat 23 and the rotating member 12 or the base assembly 11 is increased, which is beneficial to reducing the heat transfer from the igniter 2 to the rotating member 12 and the base assembly 11, thereby reducing the temperature rise of the base assembly 11 and the rotating member 12.

[0068] In the present embodiment, the swing arm 13 includes a swing arm body 131, which is in a "U" shape. The two free ends of the swing arm body 131 are respectively arranged on the opposite outer sides of the support 123 of the rotating member 12, and are detachably connected to the support 123. The end of the swing arm body 131 close to the connecting seat 23 on the igniter 2 is detachably connected to the vertical section 2302 of the connecting seat 23 by at least one screw. Furthermore, in order to reduce the heat transfer between the swing arm body 131 and the igniter, a plurality of screw holes (not shown in the figure) are provided on the swing arm body 131. The end of the screw hole close to the igniter protrudes from the side of the swing arm body 131 facing the igniter. When the arm body 131 is connected to the connecting seat 23 on the igniter by screws, the contact area between the swing arm body 131 and the connecting seat 23 can be effectively reduced.

[0069] In addition, the swing arm 13 includes a first extension portion 132 and / or a second extension portion 133. The first extension portion 132 is arranged vertically and its upper end is integrally formed with the swing arm body 131. The first extension portion 132 is detachably connected to the vertical section 2302 of the connecting seat 23 by at least one screw, so as to further enhance the reliability of the connection between the swing arm 13 and the connecting seat 23. The second extension portion 133 is arranged obliquely in the vertical direction, and the free end of the second extension portion 133 is lower than its fixed end. A movable portion (not shown in the figure) is detachably mounted on the free end of the second extension portion 133. The movable portion is used to move with a preset position (i.e., the top of the protrusion 611 on the housing assembly 61, see FIG. Fig.10 ) sliding connection, so that when the fire distributor rotates relative to the base assembly 11, the rotation resistance is smaller, ensuring smoother rotation.

[0070] It is particularly noted that the rotation of the rotating member 12 can be adjusted manually or electrically. Figure 1-4The base mechanism 1 also includes a driver 14, which is installed on the base assembly 11 and has an output end drivingly connected to the rotating member 12 for driving the rotating member 12 to drive the ignition distributor to rotate.

[0071] A lower mounting groove 113 opening downward and a side mounting groove 114 opening radially outward 712 are provided on the base body 1101 of the base assembly 11. The lower mounting groove 113 penetrates the bottom surface of the base body in the base assembly 11. The side mounting groove 114 is located above the lower mounting groove 113 and penetrates the outer side wall of the base body. The side mounting groove 114 is connected with the lower mounting groove 113 and the annular groove 112 respectively. The driver 14 is fixedly installed in the lower mounting groove 113 from bottom to top, and its output end extends upward into the side mounting groove 114. An active part (not shown in the figure) that can rotate and is mounted outside the output end is provided in the side mounting groove 114, and a driven part 121 connected to the active part is provided on the inner side wall of the rotating member 12. Therefore, through the cooperation between the active part and the driven part 121, the output end of the driver 14 is reliably connected to the rotating member 12.

[0072] In addition, a vertically arranged upper through hole 115 is provided on the base body 1101 of the base assembly 11. The upper through hole 115 is located above the side mounting groove 114, and its lower end is connected to the side mounting groove 114, and its upper end passes through the top surface of the base body in the base assembly 11, so that the base body 1101 can be quickly demoulded after being integrally formed. The upper cover plate 1104 of the base assembly 11 covers the upper end surface of the upper through hole 115.

[0073] refer to Figure 1-4 A wire threading hole 116 is vertically arranged and passes through the upper and lower end surfaces of the base assembly 11. The wire threading hole 116 passes through the base body 1101 and the upper cover 1104 respectively. A wire 17 is vertically passed through the wire threading hole 116. The upper and lower ends of the wire 17 protrude from the upper and lower end surfaces of the wire threading hole 116 respectively. The lower end of the wire 17 is used to connect to a power source and / or a controller, and the upper end is used to connect to an ignition assembly, so as to fully utilize the base assembly 11.

[0074] A first wire pressing member 16 is detachably mounted on the top of the base assembly 11, and the first wire pressing member 16 presses the wire 17 tightly against the top of the base assembly 11; in addition, a first wire pressing member 16 is detachably mounted on the top of the swing arm 13, and the first wire pressing member 16 is used to press the wire 17 tightly against the top of the swing arm 13. Thus, through the two first wire pressing members 16, the wire 17 can be stably and reliably mounted on the base mechanism 1.

[0075] Furthermore, in order to prevent the wire 17 from being easily entangled when the rotating member drives the ignition distributor to rotate, a positioning portion 117 extending upward is provided on the top of the base assembly 11, and the wire 17 is arranged outside the positioning portion 117, and it can move between abutting the positioning portion 117 and moving away from the positioning portion 117, refer to Figure 1-2 .

[0076] Example 2

[0077] refer to Figure 7-8 This embodiment also provides an upper air inlet burner, including a base mechanism as described in Example 1, and also including an igniter 2, an ignition assembly 3 and a fire cover assembly 5. The igniter 2 is rotatably arranged outside the base mechanism 1, and the igniter 2 includes an igniter head 21, an ejector tube 22 and a connecting seat 23. The igniter head 21 has a mixing chamber 211 that opens upward, and a fire cover assembly 5 is provided on the top of the mixing chamber 211. The fire cover assembly 5 is provided with an ignition hole group and / or at least one groove. The ejector tube 22 is transversely arranged outside the igniter head 21 and is integrally formed with the igniter head 21. The air outlet end of the ejector tube 22 is connected to the mixing chamber 211, and the air inlet end is connected to any nozzle 111. The connection seat 23 is arranged outside the ejector tube 22 and the igniter head 21, and is fixedly connected to the igniter head 21 and / or the ejector tube 22. The connection seat 23 is detachably connected to the rotating member 12 through the swing arm 13. Of course, the swing arm 13 can also be omitted, and the connection seat 23 is directly detachably connected to the rotating member 12. An ignition assembly 3 is detachably mounted on the connection seat 23, and the ignition assembly 3 has dual functions of ignition and flameout sensing.

[0078] Therefore, by detachably connecting the connecting seat 23 on the ignition divider 2 to the rotating part 12, and making the ejector tube 22 on the ignition divider 2 suitable for being connected to any nozzle 111, the ignition divider 2 can rotate relative to the base assembly 11 following the rotating part 12, so that the ignition divider 2 can switch between different positions, ensuring that the upper air inlet burner can meet a variety of usage states and better meet the user's usage needs.

[0079] In this embodiment, the connection seat 23 is integrally formed with the ignition distributor head 21 and the ejection tube 22. The left and right outer side walls of the ignition distributor head 21 are respectively fixed with connection arms 212 extending backwards. The two connection arms 212 are respectively located on the left and right outer sides of the ejection tube 22. The free end of at least one connection arm 212 is fixedly connected to the connection seat 23. In this embodiment, the free end of the left connection arm 212 is used for detachable connection with the outer cover 4 of the upper air inlet burner. Fig. 9 The free end of the right connecting arm 212 is integrally formed with the connecting seat 23, reference Figure 7-8Thus, the arrangement of the two connecting arms 212 is not only conducive to improving the overall connection strength of the ignition distributor 1, but also facilitates the detachable connection of the outer cover 4 to the ignition distributor head 21, so that some parts of the ignition distributor 2 can be shielded by the outer cover, making the appearance of the burner more beautiful.

[0080] refer to Figure 8 The connecting seat 23 includes a transverse section 2301 and a vertical section 2302 which are fixedly connected to form an "L" shape. Of course, the transverse section 2301 and the vertical section 2302 can also be designed to be connected to form an inverted "T" shape. The vertical section 2302 is sleeved outside the air inlet end of the ejector tube 22 and is formed integrally with the ejector tube 22 and the rear end of the transverse section 2301. A plurality of connecting holes 237 are provided on the vertical section 2302. Through the connecting holes 237 and matching screws, the vertical section 2302 can be detachably connected to the swing arm 13, so that the ignition device 2 and the base mechanism 1 can be detachably connected as a whole.

[0081] The transverse section 2301 is arranged outside the right side of the ejector tube 22 and is respectively formed integrally with the igniter head 21 and the ejector tube 22. A fixing seat 231 is fixedly provided at one end of the transverse section 2301 close to the igniter head 21. The fixing seat 231 is used to fix the ignition assembly 3. The ignition assembly 3 can be detachably mounted on the fixing seat 231 of the connecting seat 23.

[0082] In addition, a wire pressing piece 24 is detachably installed on the top of one end of the transverse section 2301 away from the igniter head 21, and the fixing seat 231 is located between the wire pressing piece 24 and the igniter head 21. The wire of the ignition assembly is compressed by the wire pressing piece 24 to realize reliable positioning of the wire and prevent the wire of the ignition assembly from being easily entangled. In the present embodiment, the position of the wire pressing piece 24 corresponding to the top of the transverse section 2301 is integrally formed with a support platform 234 extending upward, and the wire pressing piece 24 is detachably installed on the top of the support platform 234 by screws. Thus, by the setting of the support platform 234, the overall strength of the connecting seat 23 is strengthened, and the wire of the ignition assembly 3 is conveniently raised to avoid contact between the wire and the top surface of the transverse section 2301.

[0083] It is particularly noted that, in order to reduce the friction force when the fire distributor 2 rotates, a movable part can be detachably installed at the bottom of the fire distributor. When the second extension 133 of the swing arm 13 is provided with the movable part 15, the movable part at the bottom of the fire distributor 2 can be omitted or not omitted.

[0084] Example 3

[0085] refer to Fig. 9The difference between this embodiment and the second embodiment is that the upper air inlet burner further comprises an outer cover 4, one end of the outer cover 4 is disposed outside the upper end of the base mechanism 1, and the other end is disposed outside the end of the ignition distributor 2 close to the base mechanism 1 and is detachably connected to the ignition distributor 2. Thus, the outer cover 4 can shield the wire 17 and other parts of the ignition assembly on the burner, making the appearance of the upper air inlet burner more beautiful.

[0086] A plurality of vent holes 41 are provided on the side wall of the outer cover 4 at positions corresponding to the air inlet ends of the ejector tubes 22. External air can flow into the outer cover 4 through the vent holes 41, so that the ejector tubes can draw in more air, thereby mixing the gas and air evenly.

[0087] Example 4

[0088] refer to Figure 10-12 This embodiment also provides a stacked fire stove, including a shell assembly 61, a first burner 71 and an upper air inlet burner as described in Example 2 or 3. The first burner 71 has at least an outer ring fire, which is partially or completely installed on the top of the shell assembly 61. A central cavity 711 opening upward is provided at the center of the first burner 71, and the central cavity 711 is suitable for accommodating the fire cover assembly 5, the ignition assembly 3 and part of the ignition divider 2 of the upper air inlet burner; a side opening 712 is provided at the lower end of the outer wall of the first burner 71, and the side opening 712 is connected to the central cavity 711. Part or all of the base mechanism 1 is installed on the top of the shell assembly 61 and is located outside the first burner 71, and the ignition divider 2 can drive the fire cover assembly 5 and the ignition assembly 3 to move through the side opening 712 into the central cavity 711, or drive the fire cover assembly 5 to move away from the first burner 71 through the side opening 712.

[0089] In this embodiment, the upper air inlet burner has an inner ring fire, and its power can be infinitely adjusted between 0.5-3KW. The maximum power of the first burner 71 is 5.2KW, and the minimum power of the first burner 71 is greater than the maximum power of the upper air inlet burner (i.e. 3KW) or the minimum power of the upper air inlet burner (i.e. 0.5KW).

[0090] When the ignition distributor 2 drives the fire cover assembly 5 and the ignition assembly 3 to pass through the side opening 712 and move away from the first burner 71, the upper air inlet burner is located outside the first burner 71. Figure 10-11 At this time, the upper air inlet burner is in the original position, the upper air inlet burner can be used alone to form a low-fire use state, and the first burner 71 can be used alone to form a high-fire use state.

[0091] When the ignition distributor 2 drives the fire cover assembly 5 and the ignition assembly 3 to move through the side opening 712 into the central cavity 711, the upper air inlet burner is located at the center of the first burner 71. Fig.12At this time, the upper air inlet burner is in the stacked position, and the first burner 71 and the upper air inlet burner are stacked together to form a stacked burner. Compared with the first burner 71 or the upper air inlet burner used alone, the power of the stacked burner can be inorganically adjusted between 0.5-8.2KW, which meets the needs of larger fires, thereby meeting the user's stir-frying requirements. In addition, compared with the first burner 71, when the upper air inlet burner is used alone in the original position or the stacked position, it can meet the needs of smaller fires, thereby meeting the user's requirements for slow cooking with a small fire.

[0092] In this embodiment, a protrusion 611 extending upward is fixedly provided on the top of the shell assembly 61, and a notch 612 is provided on the rear outer side of the protrusion 611. At least part of the base mechanism 1 is installed at the notch 612, and the first burner 71 and the ignition divider 2 are installed on the top of the protrusion 611. The ignition divider 2 can move along the top surface of the protrusion 611.

[0093] In order to further enhance the overall appearance of the stacked fire stove, the stacked fire stove further comprises an upper panel 62, which is arranged above the shell assembly 61 and is sleeved outside the upper end of the first burner 71. A first mounting port 621 located outside the first burner 71 is provided on the upper panel 62. The ignition distributor 2 and the fire cover assembly 5 can move between the upper panel 62 and the top of the shell assembly 61, and the fire cover assembly 5 can follow the ignition distributor 2 to move between the central cavity 711 and directly below the first mounting port 621. When the fire cover assembly 5 moves to directly below the first mounting port 621, the upper air inlet burner is in the original position.

[0094] refer to Figure 10-12 Furthermore, the stacked stove also includes a second burner 72. The first burner 71 is arranged on the top right side of the shell assembly 61, and the original position of the upper air inlet burner is arranged in the top middle of the shell assembly 61. The second burner 72 is installed on the top left side of the shell assembly 61. In this embodiment, the second burner 72 is a conventional burner, which has at least an inner ring fire and an outer ring fire. The maximum power of the second burner 72 is 5.2KW, and the minimum power is greater than 0.5KW, which is used to meet the user's conventional cooking needs.

[0095] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
