By arranging the outer fire holes 121 and the outer ring flame transfer holes 122 on the first annular wall 12, they are not easily blocked, and the overflow liquid can be prevented from entering the ring mixing chamber, reducing the cleaning dead corners and improving the user experience.

[0031] In a preferred embodiment of the present utility model, as Figures 1-3The first annular wall 12 and the second annular wall 13 shown are respectively provided with notches 10. On both sides of the outer ring air passage 101 close to the notch, there are respectively fire transfer hole walls 16, and each fire transfer hole wall 16 is respectively connected between the first annular wall 12 and the second annular wall 13 on the same side. As Figures 2-3 At both ends of the first annular wall 12 close to the notch 10, there are respectively fire transfer hole walls 16. One end of each fire transfer hole wall 16 is connected to the first annular wall 12, and the other end extends inward and is connected to one end of the second annular wall 13 on the same side close to the notch 10; on the one hand, the fire transfer hole wall 16 can axially seal the outer ring air passage 101, and can also be provided with a fire transfer groove 17 for flame transfer, improving the combustion, transfer efficiency and ignition efficiency of the flame.

[0032] In a preferred embodiment of the present invention, as Figures 1-3 On the side of the fire transfer hole wall 16 and the second annular wall 13 close to the notch 10, there are provided a plurality of fire transfer grooves 17. The fire transfer grooves 17 are placed below the burner cap, and are not easily contaminated and blocked, which can make the ignition success rate and fire transfer success rate of the burner higher.

[0033] In a preferred embodiment of the present invention, as Figures 1-3 The bottom of the burner cap shown is connected with a flame distributor. The flame distributor includes an outer ring groove corresponding to the outer ring air passage 101. At the bottom of the first annular wall 12, there is an annular protrusion 123, and the annular protrusion 123 can be inserted into the outer ring groove to limit the relative position of the burner cap and the flame distributor, realizing the rapid assembly of the burner cap and the flame distributor.

[0034] In a preferred embodiment of the present invention, the flame distributor is connected with an ignition needle. The ignition needle is arranged below the cover plate 11 and on the side close to the notch 10. Arranging the ignition needle below the cover plate 11 can avoid being contaminated, improving the ignition efficiency and the service life of the ignition needle 4.

[0035] In a preferred embodiment of the present invention, as Figures 1-3 The cover plate 11 shown includes a first annular plate section 112 at the outer periphery and a second annular plate section 113 at the inner periphery of the first annular plate section 112.

In this application, the upper surface of the cover plate 11 is a smooth surface. Among them, the second annular plate section 113 is provided with inner fire holes 110, so that the overflow liquid falling on the second annular plate section 113 can quickly flow to the outside of the cover plate 11, avoiding the problem that the overflow liquid enters the inner ring air passage 102 from the inner fire holes 110 on the second annular plate section 113 and then contaminating the burner.

[0036] In a preferred embodiment of the present utility model, as Figures 1-3 shown, the upper surface of the first annular plate segment 112 slopes upward gradually from the outside to the inside, wherein the inclination angle of the second annular plate segment 113 is greater than the inclination angle of the upper surface of the first annular plate segment 112. The advantage of this design is that the overflow liquid on the second annular plate segment 113 quickly flows to the first annular plate segment 112, and the first annular plate segment 112 can slow down the outward flow rate of the overflow liquid, avoiding the overflow liquid flowing onto the stove top or the user too quickly and improving the safety performance of the product.

The projected area of the anti-overflow plate 21 on the bottom surface of the burner body 1 is larger than the air outlet area of the through hole 110 to block the air outlet end of the air supply channel 100. The top surface of the anti-overflow plate 21 is a curved surface that radiates from the middle to the periphery and gradually decreases in height. The longitudinal section of the anti-overflow plate 21 can be an upwardly convex arc or a V shape, and the anti-overflow plate 21 can completely block the air outlet end of the air supply channel 100, so that the liquid falling on the anti-overflow plate 21 can quickly flow to the cover plate 11 and be discharged to the outside of the burner, avoiding being contaminated by overflow liquid or the like.

[0038] In a preferred embodiment of the present utility model, as Figures 1-3 shown, the anti-overflow assembly 2 further includes a support rod 22, and the support rod 22 is connected between the top of the through hole 110 and the anti-overflow plate 21 so that there is a gap 20 between the anti-overflow plate 21 and the cover plate 11.

[0039] In addition, there can be multiple support rods 22. The anti-overflow plate 21 is arranged above the through hole 110, and the multiple support rods 22 are evenly distributed along the inner circumference of the through hole 110. Each. Wherein, the diameter of the anti-overflow plate 21 is larger than the diameter of the through hole 110.
