DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] To deepen the understanding of the present utility model, the present utility model will be further described in detail below in conjunction with the embodiments and the drawings. The present utility model can be implemented in the following manner:

[0030] Referring to Figures 1-5 , a burner for a gas stove includes a burner main body 1, a fire cover 2 and a bottom cup 3;

[0031] Among them, an outer ring air cavity 11 and an inner ring air cavity 12 are arranged in the main body 1 of the fire distributor. The outer ring air cavity 11 and the inner ring air cavity 12 are concentric circles, and the outer ring air cavity 11 surrounds the inner ring air cavity 12. Outer ring fire tooth flanges 13 and inner ring fire tooth flanges 14 are respectively arranged on the outer edges of the outer ring air cavity 11 and the inner ring air cavity 12; a number of fire teeth 15 are evenly distributed on the outer ring fire tooth flanges 13 and the inner ring fire tooth flanges 14, and gas injection notches 16 for gas to eject are arranged between two adjacent fire teeth 15. A gas injection notch 151 is arranged at the top of the fire tooth 15. The bottoms of the gas injection notch 16 and the gas injection notch 151 are inclined surfaces 152 that slope obliquely upward in the radial direction.

[0032] The fire cap 2 is detachably arranged above the main body 1 of the fire distributor. The fire cap 2 includes an inner fire cap 21 and an outer fire cap 22. The inner fire cap 21 is used to cover the inner ring air cavity 12, and the outer fire cap 22 is used to cover the outer ring air cavity 11. The outer fire cap 22 is a hollow circular ring in the shape of an inverted frustum; an ejection inclined surface 221 for leading the gas to the outer ring fire tooth flange 13 is arranged at the bottom of the outer fire cap 22. The inclination of the ejection inclined surface 221 is the same as that of the inclined surface 152 of the gas injection notch 16 and the gas injection notch 151. The structure of the above ejection inclined surface 221 uses the inclined surface 152 to discharge gas, which can make the gas combustion smoother.

[0033] The bottom cup 3 is detachably arranged below the main body 1 of the fire distributor; an outer ring air inlet channel and an inner ring air inlet channel are formed between the main body 1 of the fire distributor and the bottom cup 3; a large inner cavity 31 communicating with the outer ring air inlet channel and the inner ring air inlet channel is arranged inside the bottom cup 3. An ejection pipe through hole 32 for the ejection pipe to pass through is arranged on the bottom cup 3. There are two ejection pipe through holes 32, one for installing the outer ring ejection pipe and the other for installing the inner ring ejection pipe.

[0034] The large inner cavity 31 includes an air inlet cavity 311 and a gas mixing channel 312 communicating with the air inlet cavity 311. A notch 3111 for air to enter is arranged at the top of the air inlet cavity 311. The gas mixing channel 312 extends from the air inlet cavity 311 along the radial direction to the edge of the bottom cup 3 all the time. The air outlet ends of the gas mixing channel 312 are respectively communicated with an outer ring air outlet cavity one 313 and an outer ring air outlet cavity two 314. The outer ring air outlet cavity one 313 and the outer ring air outlet cavity two 314 are symmetrically arranged. Outer ring air outlet holes one 17 and outer ring air outlet holes two 18 communicating with the outer ring air cavity 11 are arranged at the positions corresponding to the upper parts of the outer ring air outlet cavity one 313 and the outer ring air outlet cavity two 314 on the main body 1 of the fire distributor. The outer ring air outlet cavity one 313, the outer ring air outlet cavity two 314, the outer ring air outlet holes one 17 and the outer ring air outlet holes two 18 form an outer ring air inlet channel.

[0035] A central inner ring air inlet cavity 33 is provided in the bottom cup 3. The inner ring air inlet cavity 33 is connected with two air inlet grooves 34 respectively communicating with the outer ring air outlet cavity one 313 and the outer ring air outlet cavity two 314. The two air inlet grooves 34 are symmetrically arranged. An inner ring air outlet hole 19 communicating with the inner ring air inlet cavity 33 is provided in the inner ring air cavity 12. The two air inlet grooves 34, the inner ring air inlet cavity 33 and the inner ring air outlet hole 19 form an inner ring air inlet passage. The air inlet cavity 311, the gas mixing passage 312, the outer ring air outlet cavity one 313 and the outer ring air outlet cavity two 314 form a large inner cavity 31 for sufficient mixing of fuel gas and air, increasing the mixing ratio of fuel gas and air, making the mixing more sufficient, the combustion firepower greater and the flame bluer.

[0036] The large inner cavity 31 is connected with a fuel gas inlet part 35 which can increase the flow rate of fuel gas. The fuel gas inlet part 35 is communicated with the air inlet cavity 311. An outer air inlet hole 351 and an inner air inlet hole 352 which are communicated with each other are provided in the fuel gas inlet part 35. The outer air inlet hole 351 is close to the outer port of the fuel gas inlet part 35. The inner air inlet hole 352 is communicated with the large inner cavity 31. The inner air inlet hole 352 is arranged obliquely above the outer air inlet hole 351. The staggered design of the outer air inlet hole 351 and the inner air inlet hole 352 can achieve the purpose of throttling. The diameters of the outer air inlet hole 351 and the inner air inlet hole 352 are gradually reduced, which can increase the flow rate of fuel gas entering the large inner cavity 31. The pressure in the air inlet cavity 311 is much lower than the atmospheric pressure, so as to improve the entrainment force of fuel gas and quickly bring air into the air inlet cavity 311, increasing the air intake and making the fuel gas combustion more sufficient.

[0037] Working principle: The fuel gas enters through the fuel gas inlet part 35 and is ejected through the nozzle into the air inlet cavity 311. At the same time, the entrainment force of the fuel gas is used to bring air from the notch 3111 on the air inlet cavity 311 into the air inlet cavity 311, and then it enters the outer ring air outlet cavity one 313 and the outer ring air outlet cavity two 314 through the gas mixing passage 312 in sequence. A part of the mixed gas in the outer ring air outlet cavity one 313 and the outer ring air outlet cavity two enters the outer ring air cavity 11 through the outer ring air outlet holes one 17 and two 18, and then is ejected from the gas ejection notch 16 and the gas ejection gap 151 positions of the outer ring fire tooth flange 13 to ignite the combustion; another part enters the inner ring air cavity 12 through the air inlet grooves 34, the inner ring air inlet cavity 33 and the inner ring air outlet hole 19 in sequence, and then is ejected from the gas ejection notch 16 and the gas ejection gap 151 positions of the inner ring fire tooth flange 14 to ignite the combustion.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
