[0035] Example 1

[0036] The burner provided in this embodiment is as follows: Figures 1 to 7 As shown, it includes an air distribution plate 3 and a guide component 8; the air distribution plate 3 includes an outer cavity, and the outer cavity is provided with an air inlet channel 33; the guide component 8 includes a base 82 and a guide member 81; the base 82 is arranged in the outer cavity; the base 82 is provided with a through hole 823, and the through hole 823 is connected to the top opening of the air inlet channel 33; the guide member 81 is arranged above the through hole 823, and the guide member 81 is rotatably connected to the base 82, and the guide member 81 can rotate toward or away from the through hole 823.

[0037] When the gas stove is turned on, the gas mixture is ejected from the air outlet channel 51 of the burner 5 and enters the air inlet channel 33 of the gas distribution plate 3. The guide member 81 arranged above the top opening of the air inlet channel 33 is impacted by the gas flow and rotates away from the through hole 823. The distance between the guide member 81 and the top opening of the air inlet channel 33 increases, meeting the needs of the peripheral main fire combustion; when the gas stove is turned off, the guide member 81 rotates toward the through hole 823, and the distance between the guide member 81 and the top opening of the air inlet channel 33 decreases, which can effectively prevent the flame from being transferred to the cavity of the burner 5 when the flame is turned off, thereby reducing the flameout noise.

[0038] The base 82 may be in a plate shape, a block shape, or any other suitable form.

[0039] The base 82 is arranged in the outer cavity, and the through hole 823 is arranged above the top opening of the air inlet channel 33, so that the through hole 823 is connected with the top opening of the air inlet channel 33; the guide member 81 is arranged above the through hole 823, and the guide member 81 is also arranged above the top opening of the air inlet channel 33.

[0040] The guide member 81 may be a guide plate, a guide block or any other suitable form.

[0041] When the gas stove is off, the distance between the deflector 81 and the through hole 823 is minimal, and the deflector 81 is in its initial position. When the deflector is in its initial position, the deflector 81 can be arranged parallel to the base 82 or tilted relative to the base 82. In this embodiment, when the deflector is in its initial position, the deflector 81 is arranged parallel to the base 82, with a gap between them.

[0043] The elastic member may be a clip spring 83 or a compression spring or any other suitable form.

[0044] When the gas stove is turned on, the gas mixture is ejected from the outlet channel 51 of the burner 5 and enters the inlet channel 33 of the gas distribution plate 3. The guide member 81 arranged above the top opening of the inlet channel 33 is impacted by the gas flow, compressing the elastic member and rotating away from the through hole 823; when the gas stove is turned off, under the elastic force of the elastic member, the guide member 81 automatically rotates toward the through hole 823 to its initial position.

[0045] The elastic member can help the flow guide member 81 return to its initial position to ensure that the flow guide member 81 works normally.

[0046] In an optional embodiment, a rotating shaft is provided on both sides of the guide member 81, and a mounting member 821 is provided on the base 82. The mounting members 821 are respectively arranged on both sides of the through hole 823. The rotating shaft is rotatably connected to the mounting member 821. The guide member 81 can rotate toward or away from the through hole 823 around the axis of the rotating shaft. The elastic member is a torsion spring, which is connected between the base 82 and the guide member 81.

[0047] Furthermore, a mounting member 821 is provided on the base 82, and the mounting members 821 are respectively arranged on both sides of the through hole 823; a connecting portion 811 is respectively provided on both sides of the guide member 81; the elastic member is a retaining spring 83, one end of the retaining spring 83 is connected to the base 82, and the other end of the retaining spring 83 is connected to the connecting portion 811.

[0048] A first through hole is provided on the end surface of the mounting member 821 facing the center of the base 82, and one end of the retaining spring 83 passes through the first through hole and is fixed to the mounting member 821; a second through hole is provided on the top surface of the connecting portion 811, and one end of the retaining spring 83 passes through the second through hole and is fixed to the connecting portion 811.

[0049] When the gas stove is turned on, the gas mixture is ejected from the air outlet channel 51 of the burner head 5 and enters the air inlet channel 33 of the gas distribution plate 3. The guide member 81 arranged above the top opening of the air inlet channel 33 is impacted by the gas flow and compresses the retaining spring 83 and rotates away from the through hole 823; when the gas stove is turned off, the retaining spring 83 returns to its original state and drives the guide member 81 to rotate toward the through hole 823 to its initial position.

[0050] Furthermore, the base 82 is provided with a first positioning member, and the peripheral cavity is provided with a second positioning member. The first positioning member and the second positioning member are cooperatively connected to position the base 82 along the circumference of the base 82.

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.

[0057] 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 mounting hole 44 is provided on the diverter plate 4. After the screw passes through the mounting hole 44, the screw is locked with the gas distribution plate 3, thereby fixing the diverter plate 4 below the gas distribution plate 3.

[0059] A second notch 42 is provided on the outer edge of the manifold 4 , and the air inlet passage 33 extends into the second notch 42 , so that the manifold 4 can avoid the air inlet passage 33 , facilitating the installation of the manifold 4 and the gas distribution plate 3 .

[0072] In this embodiment, the third positioning member is a groove, which is provided on the mounting base of the thermocouple 6 , and the fourth positioning member 32 is a pin, which is plugged into the groove.

[0073] Example 2

[0074] The gas stove provided in this embodiment includes the burner provided in Example 1. When the gas stove is turned on, the gas mixture is ejected from the gas outlet channel 51 of the burner head 5 and enters the gas inlet channel 33 of the gas distribution plate 3. The guide member 81 disposed above the top opening of the gas inlet channel 33 is impacted by the gas flow and rotates away from the through hole 823. The distance between the guide member 81 and the top opening of the gas inlet channel 33 increases, meeting the requirements of peripheral main flame combustion. When the gas stove is turned off, the guide member 81 rotates toward the through hole 823, and the distance between the guide member 81 and the top opening of the gas inlet channel 33 decreases. This effectively prevents 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.
