Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

As shown in fig. 1 to 4, the preferred embodiment of the present invention is shown. The burner fire cover for the gas stove comprises a fire cover body 1, a main fire hole 12 is formed in the circumferential direction of an annular circumferential wall 11 of the fire cover body 1, a flame stabilizing groove 13 intersecting with the main fire hole 12 is formed in the circumferential direction of the annular circumferential wall 11, two rows of first flame stabilizing holes 14 and second flame stabilizing holes 15 are formed in the annular circumferential wall 11 below the main fire hole 12 and are arranged at intervals up and down, the first flame stabilizing holes 14 are communicated with the flame stabilizing groove 13, and a first wall surface 16 corresponding to the second flame stabilizing holes 15 is radially inwards contracted. The flame stabilizing groove 13 intersected with the main flame hole 12 is arranged to form a flame stabilizing part of the main flame hole 12, the second flame stabilizing to the main flame hole 12 is strengthened through the first flame stabilizing hole 14 communicated with the flame stabilizing groove 13, and finally the third flame stabilizing is started to the main flame hole 12 through the second flame stabilizing hole 15 which is radially inwards contracted, so that the triple flame stabilizing can obviously improve the combustion efficiency of the gas stove while stabilizing the main flame hole 12; the gas stove with the burner fire cover is also provided, the second flame stabilizing hole 15 is concealed in the base 2, so that the third flame stabilizing can be better realized, and the flame stabilizing effect is finally and effectively improved.

Specifically, in order to enhance the flame holding of the second flame holding holes 15, the annular peripheral wall 11 of the present embodiment further includes a second wall surface 17 on the first wall surface 16, and each of the second flame holding holes 15 is further intersected by a corresponding intersecting hole 18, and the intersecting hole 18 is located at an intersecting step 19 of the first wall surface 16 and the second wall surface 17. Wherein each second flame stabilizing hole 15 also intersects through a respective intersecting hole 18, the advantage of this arrangement is that: 1. when even large overflowing liquid flows to the first wall surface 16 along the second wall surface 17 of the annular peripheral wall 11, the second flame stabilizing holes 15 can 'flush' the overflowing liquid due to the mixed gas of the primary air and the fuel gas flowing out of the corresponding intersecting holes 18, so that blockage is avoided; 2. because the aperture of the intersecting hole 18 is large, even if overflowing liquid flows into the second flame stabilizing hole 15, the overflowing liquid can flow out, and because the intersecting hole 18 is arranged at the intersecting step 19, namely the position below the intersecting step 19 is basically suspended, the overflowing liquid can drop according to the gravity of the overflowing liquid, and the overflowing liquid is not easy to flow into the second flame stabilizing hole 15. Wherein, the flame stabilizing groove 13 is inclined upwards and gradually approaches the main fire hole 12 from outside to inside, thus avoiding overflowing liquid from blocking the overflowing flame stabilizing groove 13.

In addition, the present embodiment also provides a burner using the burner fire cover, the burner includes a base 2 for supporting the fire cover body 1, the first wall surface 16 of the fire cover body 1 is located inside the base 2, and the first wall surface 16 is further provided with ribs 161 protruding from the first wall surface 16 at intervals along the circumferential direction below the second flame stabilizing holes 15, and a fire outlet channel 21 communicating with the second flame stabilizing holes 15 is formed between each rib 161 and the base 2. The second flame stabilizing hole 15 is skillfully concealed in the base 2 because of the flame outlet channel 21, thus effectively avoiding the overflowing liquid from blocking the second flame stabilizing hole 15, and further playing a better flame stabilizing role for the main flame hole 12. In order to realize that the flame formed by the second flame stabilizing hole 15 can flow out of the flame outlet channel 21, the base 2 of the burner is internally provided with a supporting part 22 with an L-shaped section, the supporting part comprises a transverse part 221 for the lower end part of the annular peripheral wall 11 of the fire cover body 1 to rest, and a vertical part 222 forming the flame outlet channel 21 with each convex rib 161, and the top of the vertical part 222 and the intersection step 19 form an outlet port 210 of the flame outlet channel 21. And, a flow guide portion 20 for guiding the overflowing liquid is provided below the vertical portion 222 of the base 2 adjacent to the outlet 210. The overflow liquid can be guided to the outside of the fire outlet channel 21 along the annular peripheral wall 11 of the fire cover body 1 through the guiding part 20, so that the second flame stabilizing hole 15 can be blocked by the overflow liquid, and meanwhile, the guiding part 20 is gradually inclined to the direction far away from the outlet 210 from top to bottom, so that the overflow liquid can be guided to the outside of the second flame stabilizing hole 15.

In summary, the main fire hole 12 of the burner fire cover for the gas stove performs triple flame stabilization through the flame stabilizing groove 13, the first flame stabilizing hole 14 and the second flame stabilizing hole 15, and the second flame stabilizing hole 15 is concealed in the base 2, so that the second flame stabilizing hole 15 can be better prevented from being blocked by overflowing liquid.
