[0039] The following examples are used to illustrate the present application, but the present application is not limited by these examples. Modifications to the specific embodiments of the present application or equivalent replacements to some technical features are made without departing from the spirit of the present application, which should be covered in the technical solution range claimed by the present application.

[0040] Please refer to Figures 1-6 The present application provides a gas stove, which comprises a gas supply base 5, a fire dividing structure, an inner fire cover 1 and an outer fire cover 2. The inner ring gas inlet passage and the outer ring gas inlet passage are formed in the gas supply base 5. The fire dividing structure is installed on the gas supply base 5. The inner fire cover 1 is installed on the fire dividing structure and cooperates with the fire dividing structure to form an inner ring air passage 100 which is in communication with the inner ring gas inlet passage. The inner fire cover 1 is provided with an inner fire hole 11 which is in communication with the inner ring air passage 100. The outer fire cover 2 is installed on the fire dividing structure and cooperates with the fire dividing structure to form an outer ring air passage 200 which is in communication with the outer ring gas inlet passage. The outer fire cover 2 comprises an infrared radiation top plate 21 and a side plate 22 which extends downward from the periphery of the infrared radiation top plate 21. The infrared radiation top plate 21 is located outside the inner fire cover 1. The side plate 22 is provided with an outer fire hole 23 which is in communication with the outer ring air passage 200. The upper side of the outer fire cover 2 is provided with an infrared combustion hole which is in communication with the outer ring air passage 200. The aperture of the infrared combustion hole is smaller than that of the outer fire hole 23. A secondary air passage 300 is arranged between the infrared radiation top plate 21 and the inner fire cover 1. A lifting driving structure is installed on the gas supply base 5 and is in transmission connection with the inner fire cover 1 and the outer fire cover 2. The lifting driving structure can drive the inner fire cover 1 and the outer fire cover 2 to lift respectively, so that the inner fire cover 1 can lift relative to the outer fire cover 2 between a first position and a second position, and the outer fire cover 2 can lift relative to the fire dividing structure between a third position and a fourth position. When the outer fire cover 2 is located at the first position, the outer fire hole 23 extends above the fire dividing structure. When the outer fire cover 2 is located at the second position, the lower part of the outer fire hole 23 is located at one side of the fire dividing structure, and the fire dividing structure blocks the outer fire hole 23. When the inner fire cover 1 is located at the third position, the inner fire hole 11 extends above the infrared radiation top plate 21, and the inner fire cover 1 opens the secondary air passage 300.

Small fire and large air combustion mode, such as Figure 4 As shown, the outer fire cover 2 is in the second position, and the inner fire cover 1 is in the third position, at this time, the outer fire hole 23 is blocked, and the inner fire hole 11 is opened, realizing the small fire and large air combustion mode of the inner ring fire.

[0043] c. Large air combustion mode, such as Figure 5 As shown, the outer fire cover 2 is in the first position, and the inner fire cover 1 is in the fourth position, at this time, the outer fire hole 23 is opened, and the inner fire hole 11 is blocked, because the aperture of the infrared combustion hole is smaller than that of the outer fire hole 23, the gas basically flows to the outer fire hole 23 with a larger aperture, so that the amount of gas at the infrared combustion hole is less, and the secondary air passage 300 is blocked by the inner fire hole 11, so that the secondary air at the infrared combustion hole is thin, and thus the combustion flame does not occur at the secondary combustion hole;

[0044] d. Mixed combustion mode, such as Figure 6 As shown, the outer fire cover 2 is in the first position, and the inner fire cover 1 is in the third position, the inner fire hole 11 and the outer fire hole 23 are both opened, and the secondary air passage 300 is also opened, at this time, the inner fire hole 11, the outer fire hole 23, and the infrared combustion hole can all produce flames, forming a mode in which large air and infrared energy-gathering combustion coexist.

[0045] Optionally, the aperture of the outer fire hole 23 is at least ten times the aperture of the infrared combustion hole.

[0048] Optionally, the fire distribution structure comprises the fire distribution plate 4 and the fire distributor 3 arranged in the fire distribution plate 4, the fire distributor 3 is provided with an inner ring air passage, the inner ring gas inlet passage and the inner ring air passage 100 are communicated through the inner ring air passage, the fire distributor 3 is provided with an outer ring air passage between the fire distribution plate 4, the outer ring gas inlet passage and the outer ring air passage 200 are communicated through the outer ring air passage.

[0049] Optionally, when the outer fire cover 2 is located at the second position, the side plate 22 is located at the inner side of the fire distribution plate 4, and the inner wall of the fire distribution plate 4 shields the outer side of the outer fire hole 23, so that the outer fire hole 23 is shielded by the fire distribution plate 4 when the outer fire cover 2 is located at the second position, and the appearance is beautiful.

[0050] Optionally, the ignition needle 8 is further arranged at the outer side of the fire distribution plate 4 and is aligned with the outer fire cover 2, so as to realize the ignition function of the gas stove.
