Detailed Description

The utility model is described in further detail below with reference to the accompanying examples.

As shown in FIGS. 1 to 4, the preferred embodiment of the present invention is shown. The burner fire cover for the gas stove of the embodiment comprises an upper cover body 1, wherein the upper cover body 1 comprises an annular top wall 11, an inner annular wall 12 and an outer annular wall 14 which vertically or obliquely extend downwards from the inner edge and the outer edge of the annular top wall 11, a gas mixing cavity 15 is formed between the upper cover body 1 and the outer annular wall 14, the outer annular wall 14 is circumferentially provided with at least two first fire holes 151 communicated with the gas mixing cavity 15 at intervals, the burner fire cover further comprises a lower base body 16 positioned in the gas mixing cavity 15, the lower base body 16 is also circumferentially provided with at least two second fire holes 161 communicated with the gas mixing cavity 15 at intervals, each second fire hole 161 is sequentially communicated with the corresponding first fire hole 151 to jointly form a fire outlet part 17, the lower base body 16, the outer annular top wall 14 and the annular top wall 11 jointly enclose a liquid storage cavity 18 positioned between the first fire holes 151 and the second fire holes 161 to store overflowed liquid, and the liquid storage cavity 18 used for storing overflowed liquid is enclosed between the upper cover body 1 and the lower base body 16, therefore, the second fire outlet 161 which is the air inlet end of the final fire outlet 17 communicated with the air mixing cavity 15 can not be directly blocked by the overflowing liquid to play a role of anti-blocking.

Specifically, from the perspective of simple structure, in the lower seat 16 of the present embodiment, preferably, the lower seat 16 includes a vertical wall 162 spaced apart from the outer annular wall 14, and a horizontal wall 163 extending from a lower end of the vertical wall 162 to the outer annular wall 14, the vertical wall 162 abuts against the annular top wall 11, and the horizontal wall 163 abuts against the outer annular wall 14, so as to jointly enclose the liquid storage cavity 18, wherein the vertical wall 162 is opened with the second fire outlet 161, so that a path of the gas flowing out from the gas mixing cavity 15 and finally flowing out of the fire outlet 17 is shortest. In addition, in order to promote the combustion stability of the first flame outlet 151 and the second flame outlet 161, the vertical wall 162 is provided with a second flame stabilizing hole 164 above and/or below each second flame outlet 161 for stabilizing flame, correspondingly, the outer annular wall 14 is provided with a first flame stabilizing hole 141 above and/or below the first flame outlet 151 for stabilizing flame, and each first flame stabilizing hole 141 is sequentially communicated with its corresponding second flame stabilizing hole 164 to form the flame stabilizing part 19. Finally, in order to avoid the overflow from directly entering the first fire outlet 151, the annular top wall 11 extends outwards to form the waterproof eaves 110 capable of shielding the first fire outlet 151, the overflow can flow out of the first fire outlet 151 and not directly flow into the first fire outlet 151 through the waterproof eaves 110, the overflowing soup drops can flow to the first fire outlet 151 along the upper cover body 1 to block the first fire outlet 151, the waterproof eaves 110 is further provided with the concave-convex structures 1101 at intervals along the circumferential direction, and the concave-convex structures 1101 further extend to the annular top wall, the concave-convex structures 1101 can contain the soup drops in the cooking process, so as to slow down the speed of the overflow flowing to the first fire outlet 151, and further reduce the probability of the first fire outlet 151 being blocked.

In summary, the anti-overflow structure of the burner fire cover firstly passes through the concave-convex structure 1101 on the waterproof brim 110 to perform the anti-blocking function on the first fire outlet 151, but due to the design of the liquid storage cavity 18, after the overflow enters the liquid storage cavity 18 for storing the overflow along the first fire outlet 151, the "second fire outlet 161" serving as the air inlet end communicated with the air mixing cavity 15 in the final fire outlet 17 can not be directly blocked by the overflow to perform the anti-blocking function.
