Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0029] The utility model provides a burner and a gas stove. A plurality of embodiments are given below to describe the burner and the gas stove provided by the utility model in detail.

[0030] Example 1

[0031] The burner provided in this embodiment is as follows: Figures 1 to 6 As shown, it includes an air distribution plate 3; the air distribution plate 3 includes an air inlet channel 34, and a guide member 31 is provided above the top opening of the air inlet channel 34. The guide member 31 can be raised and lowered relative to the air inlet channel 34.

[0032] The flow guide 31 is disposed above the gas distribution plate 3 , and is located above the top opening of the air inlet channel 34 . The flow guide 31 can be raised and lowered in the vertical direction.

[0033] When the gas stove is turned on, the guide member 31 moves upward due to the impact of the gas flow, and the distance between the guide member 31 and the top opening of the air inlet channel 34 increases, meeting the needs of the peripheral main fire combustion; when the gas stove is turned off, the guide member 31 descends, and the distance between the guide member 31 and the top opening of the air inlet channel 34 decreases, which can effectively prevent the flame from being transferred to the cavity of the burner 5 when the fire is turned off, thereby reducing the noise of the fire.

[0034] The guide member 31 may be a guide plate, a guide block or any other suitable form.

[0035] The guide member 31 can be raised and lowered relative to the air inlet channel 34. In an optional embodiment, a slide rail is provided on the top surface of the gas distribution plate 3. The guide member 31 is slidably connected to the slide rail, and the guide member 31 can be raised and lowered in the vertical direction along the slide rail.

[0036] Furthermore, a guide member 32 is provided on the top surface of the gas distribution plate 3 , and the flow guide member 31 is sleeved on the guide member 32 . The flow guide member 31 can be raised and lowered along the extension direction of the guide member 32 .

[0037] The guide member 32 may be in any suitable form, such as a rod or a sheet.

[0038] The guide member 32 is fixed on the top surface of the gas distribution plate 3, and a mounting hole is provided on the guide member 31. The mounting hole is sleeved on the guide member 32, so that the guide member 31 is sleeved on the guide member 32. The extension direction of the guide member 32 is set in the vertical direction, and the guide member 31 can slide along the extension direction of the guide member 32, thereby realizing the lifting and lowering of the guide member 31.

[0039] When the gas stove is turned on, the flow guide 31 is impacted by the gas flow and moves upward; when the gas stove is turned off, the flow guide 31 descends under the action of gravity.

[0040] The number of the guide member 32 can be one or more. The guide member 32 is arranged outside the air intake passage 34 .

[0041] Furthermore, the guide members 32 are respectively provided on both sides of the air intake passage 34 .

[0042] Guide members 32 are respectively provided on both sides of the air inlet passage 34 so that one guide member 31 is guided by two guide members 32 , thereby improving the stability of the guide member 31 in ascending and descending.

[0043] Furthermore, a boss 33 is provided on the top surface of the gas distribution plate 3 , the guide member 32 is connected to the boss 33 , and the flow guide member 31 can abut against the boss 33 .

[0044] A boss 33 is fixedly provided on the top surface of the gas distribution plate 3 , and the guide member 32 is fixed on the boss 33 , so that the guide member 32 is fixed on the top surface of the gas distribution plate 3 .

[0045] When the guide member 31 descends along the guide member 32 and abuts against the boss 33 , the guide member 31 stops descending, thereby limiting the lowest descending position of the guide member 31 .

[0046] The guide member 32 and the boss 33 may be fixedly connected, such as by bonding or welding, or detachably connected, such as by threading or clamping.

[0047] Furthermore, a blind hole is provided on the top surface of the boss 33 , and the guide member 32 is plugged into the blind hole.

[0048] The guide member 32 is plugged into the blind hole, so that the guide member 32 and the boss 33 can be fixed, making it easy to disassemble and assemble the guide member 32.

[0049] Furthermore, a limiting member 321 is provided on the top of the guide member 32 . The limiting member 321 is arranged above the flow guide member 31 , and the limiting member 321 can abut against the flow guide member 31 .

[0050] The limiter 321 is fixed to the top of the guide member 32, and the guide member 31 is arranged between the limiter 321 and the boss 33. When the guide member 31 rises, it will no longer continue to rise after rising to the position where it abuts the limiter 321, thereby limiting the highest rising position of the guide member 31 and preventing the guide member 31 from sliding out of the guide member 32.

[0051] The limiting member 321 may be in a plate shape, a rod shape, or any other suitable form. In this embodiment, the limiting member 321 is in a disc shape.

[0052] The gas distribution plate 3 is provided with an outer cavity and an inner ring cavity. The outer cavity is arranged outside the inner ring cavity. The outer cavity is installed with a copper cover 2 to realize the outer ring main fire combustion. The inner ring cavity is installed with a copper core 1 to realize the center fire combustion.

[0053] Furthermore, the burner also includes a diverter plate 4 ; the diverter plate 4 is annular and fixed below the gas distribution plate 3 . A notch structure 42 is provided on the outer edge of the diverter plate 4 , and the air inlet channel 34 extends into the notch structure 42 .

[0054] The diverter plate 4 is arranged below the gas distribution plate 3. The diverter plate 4 is located between the outer cavity and the inner ring cavity. A through hole 44 is provided on the diverter plate 4. After the screw passes through the through hole 44, the screw is locked with the gas distribution plate 3, thereby fixing the diverter plate 4 below the gas distribution plate 3.

[0055] The diverter plate 4 is annular, and the central hole 43 inside the diverter plate 4 can avoid the electrode needle 7, the thermocouple 6, the center fire gas channel installation and the center fire secondary air supply.

[0056] A notch structure 42 is provided on the outer edge of the manifold plate 4 , and the air inlet channel 34 extends into the notch structure 42 , so that the manifold plate 4 can avoid the air inlet channel 34 , facilitating the installation of the manifold plate 4 and the gas distribution plate 3 .

[0057] Furthermore, the outer edge of the diverter plate 4 is provided with a flange structure 41 extending downward.

[0058] The flange structure 41 can control the size of the center fire secondary air supply inlet and enhance the strength of the diverter plate 4 .

[0059] The setting of the diverter plate 4 has a dividing effect, which can effectively prevent the impact of hot air from above (combustion area) from affecting the secondary air supply, which is conducive to the supply of secondary air required for central fire combustion under the diverter plate 4, making the combustion more complete.

[0060] Furthermore, the burner further comprises a burner head 5 ; an air outlet channel 51 is provided on the top surface of the burner head 5 , and the top surface of the air outlet channel 51 abuts against the bottom surface of the air inlet channel 34 .

[0061] There are multiple air inlet channels 34 on the air distributor plate 3 , and the multiple air inlet channels 34 are arranged at intervals along the circumference of the air distributor plate 3 .

[0062] There are multiple gas outlet channels 51 on the burner head 5 , and the multiple gas outlet channels 51 are arranged at intervals along the circumference of the burner head 5 .

[0063] The plurality of air inlet channels 34 abut against the plurality of air outlet channels 51 in a one-to-one correspondence.

[0064] Electrode needles 7 and thermocouples 6 are also provided on the top surface of the furnace head 5 .

[0065] Furthermore, a first positioning member is provided on the top surface of the burner head 5 , and a second positioning member 35 is provided on the bottom surface of the gas distribution plate 3 . The first positioning member and the second positioning member 35 are cooperatively connected.

[0066] By cooperating and connecting the first positioning member and the second positioning member 35, the furnace head 5 and the gas distribution plate 3 are circumferentially positioned so that the multiple air inlet channels 34 and the multiple air outlet channels 51 can be matched one by one to prevent dislocation and movement.

[0067] The first positioning member may be a groove, and the second positioning member 35 may be a pin. Alternatively, the first positioning member may be a pin, and the second positioning member 35 may be a groove.

[0068] In this embodiment, the first positioning member is a groove, which is provided on the mounting base of the thermocouple 6 , and the second positioning member 35 is a pin, which is plugged into the groove.

[0069] Example 2

[0070] The gas stove provided in this embodiment includes the burner provided in Example 1. When the gas stove is turned on, the guide member 31 is impacted by the gas flow and moves upward, increasing the distance between the guide member 31 and the top opening of the air inlet passage 34 to meet the requirements of peripheral main flame combustion. When the gas stove is turned off, the guide member 31 descends, reducing the distance between the guide member 31 and the top opening of the air inlet passage 34, effectively preventing the flame from being transferred to the cavity of the burner head 5 when the gas stove is turned off, thereby reducing the noise caused by the flame turning off.
