[0032] The following embodiments are used to illustrate the present invention, but the present invention is not limited by these embodiments. Modifying the specific implementation manners of the present invention or equivalently replacing some technical features without departing from the spirit of the present invention scheme shall all be covered within the scope of the technical solution claimed by the present invention.
[0033] Please refer to Figures 1-5 , the present invention provides a burner, including a flame distributor 1, an inner fire cover 2 and a buffer wall panel 14. The flame distributor 1 includes a flame distributor 1 body and an inner ring flame distribution groove 11 arranged on the upper side of the flame distributor 1 body, and flame holes 111 are opened on the inner side of the inner ring flame distribution groove 11. The inner fire cover 2 includes an inner fire cover body 21, and the inner fire cover body 21 and the inner ring flame distribution groove 11 are covered to form an inner ring flame distribution channel 100. The buffer wall panel 14 is arranged in the inner ring flame distribution groove 11 and forms a buffer cavity 101 with the inner wall of the inner ring flame distribution groove 11. An air intake opening 102 communicating with the inner ring flame distribution channel 100 is opened at the upper end of the buffer cavity 101. The flame holes 111 communicate with the buffer cavity 101, and the flame holes 111 are arranged not higher than the air intake opening 102. When the burner works, gas enters the inner ring flame distribution groove 11, then flows downward through the air intake opening 102 into the buffer cavity 101, and then flows out through the flame holes 111. After the gas is buffered in the buffer cavity 101, its direction changes and then it flows out from the flame holes 111, so that the flame can be stabilized.
[0034] Optionally, the buffer wall panel 14 and the flame distributor 1 body are integrally formed, with simple structure and easy to form and assemble.
[0035] Optionally, the width of the buffer cavity 101 is W1, and 0.5 mm ≤ W1 ≤ 0.8 mm to ensure the buffering effect.
[0036] In another embodiment, optionally, the inner side wall of the inner fire cap 2 covers the inner side wall of the inner ring fire dividing groove 11, and the buffer wall plate 14 is arranged lower than the inner side wall of the inner fire cap 2 to form an air intake gap 103 with the inner side wall of the inner fire cap 2, so as to increase the length of the buffer channel and improve the buffer effect.
[0037] In this embodiment, due to the setting of the air intake gap 103, optionally, the width W1 of the buffer chamber 101 can be set relatively wider, 0.8 mm ≤ W1 ≤ 1.2 mm. Correspondingly, in order to achieve the buffer and deceleration effect of the gas at the air intake gap 103, the width of the air intake gap 103 is W2, 0.4 mm ≤ W2 ≤ 0.8 mm.
[0038] Optionally, the flame holes 111 are ignition holes and / or inner ring fire holes 22 to achieve the flame stabilizing effect on the flames of the ignition holes and / or the inner fire holes.
[0039] In this embodiment, optionally, the inner fire cap 2 further includes inner ring fire holes 22 opened on the inner side of the inner fire cap body 21, and the flame holes 111 are ignition holes.
[0040] Optionally, it further includes an ignition needle 3, and the ignition needle 3 is arranged in the middle of the main body of the fire divider 1 and is arranged opposite to the ignition hole.
[0041] Optionally, the fire divider 1 further includes a flame stabilizing part 13 arranged on the inner side wall of the inner ring fire dividing groove 11. The flame stabilizing part 13 is located above the flame holes 111 and extends towards the center of the fire divider 1 to further improve the flame stabilizing effect.
[0042] Optionally, it further includes an outer fire cap 4. The fire divider 1 further includes an outer ring fire dividing groove 12 arranged outside the inner ring fire dividing groove 11. The outer fire cap 4 includes an outer fire cap body 41 and outer ring fire holes 42 arranged on the inner side of the outer fire cap body 41. The outer fire cap body 41 and the outer ring fire dividing groove 12 are covered to form an outer ring fire dividing channel 200.
[0043] On the other hand, the present utility model provides a gas stove, including the above-mentioned burner.
[0044] The above are only some embodiments of the present utility model. For those of ordinary skill in the art, without departing from the creative concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
