The third technical problem to be solved by the utility model is to provide a combustor for gas cooking utensils that can effectively ensure the fire protection performance in the fire protection hole to above-mentioned prior art current situation.
The utility model provides a technical scheme that above-mentioned technical problem adopted does: this a combustor for gas-cooker, including interior ring fire lid, its characterized in that: the top wall of the inner ring fire cover is a curved surface with a high center and a low periphery, and at least two guide grooves for guiding overflowing liquid are radially arranged on the top wall from the center to the periphery.
In order to prevent the fire hole from being blocked by the overflowing liquid, a gas mixing cavity is formed on the top wall of the inner ring fire cover and the annular peripheral wall which vertically extends downwards from the top wall, at least two fire holes communicated with the gas mixing cavity are formed in the annular peripheral wall at intervals along the circumferential direction, and a waterproof brim which is shielded above the fire holes is formed by extending outwards on the outer edge of the top wall.
In order to better enable overflowing liquid entering the diversion trenches to flow out through the waterproof eaves, the inlet of each diversion trench is located in the center of the top wall, and the outlet of each diversion trench at least partially penetrates through the waterproof eaves.
In order to realize that the overflowing liquid enters the waterproof eaves more slowly, the caliber of the diversion trench is gradually increased from the inlet to the outlet.
For solving the second technical problem, the utility model discloses a scheme be: the base and the thermocouple are further included, the fire outlet hole corresponding to the thermocouple is a first fire protection hole, and the number of the first fire protection holes is at least two, and the first fire protection holes are communicated with one another. Because the quantity of first fire-keeping hole is not only one, and still link up each other to make once the overflow gets into in one of them first fire-keeping hole also can not cause the jam of first fire-keeping hole.
For solving the third technical problem, the utility model discloses a scheme be: and a second fire protection hole communicated with the gas mixing cavity is further formed in the annular peripheral wall below the first fire protection hole.
Preferably, the second fire protection holes have two, i.e. are arranged in pairs, and the axes of the two second fire protection holes intersect at an acute angle. Because the number of the second fire protection holes is two, the fire can be gathered when the fire goes out, and the fire protection performance of the fire protection holes is ensured.
Compared with the prior art, the utility model has the advantages of this inner ring fire lid's roof is the low curved surface of the high periphery of central authorities, can accelerate the speed that the overflow liquid left the inner ring fire lid, in addition the guiding gutter set up to from central authorities to periphery, radially set up to realize that the overflow liquid leaves the roof from central eminence to the low department in periphery more evenly, have simple to operate, simple structure's characteristics.

Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
As shown in FIGS. 1 to 3, the preferred embodiment of the present invention is shown. The combustor for the gas stove in the embodiment comprises an inner ring fire cover 1, wherein a top wall 11 of the inner ring fire cover 1 is a curved surface with a high center and a low periphery, at least two guide grooves 111 for guiding overflow liquid are radially arranged from the center to the periphery of the top wall 11, the top wall 11 of the inner ring fire cover 1 is a curved surface with a high center and a low periphery, the speed of the overflow liquid leaving the inner ring fire cover 1 can be accelerated, and in addition, the guide grooves 111 are radially arranged from the center to the periphery, so that the overflow liquid more uniformly leaves the top wall 11 from the high center to the low periphery.
In order to further prevent the overflowing liquid from entering the fire outlet of the inner ring fire cover 1, the top wall 11 of the inner ring fire cover 1 and the annular peripheral wall 12 extending vertically downward from the top wall 11 are formed with a gas mixing cavity 13, the annular peripheral wall 12 is provided with at least two fire outlet holes 131 communicated with the gas mixing cavity 13 at intervals along the circumferential direction, and the outer edge of the top wall 11 extends outward to form a waterproof brim 112 covering the fire outlet holes 131. In order to better enable the overflow liquid entering the guiding gutter 111 to flow out through the waterproof eaves 112, the inlet 1111 of each guiding gutter 111 is located at the center of the top wall 11, the outlet 1112 of each guiding gutter 111 at least partially penetrates through the waterproof eaves 112, and meanwhile, in order to enable the overflow liquid to enter the waterproof eaves 112 more slowly, the caliber of the guiding gutter 111 gradually increases from the inlet 1111 to the outlet 1112.
In addition, the burner also comprises a base 2 and a thermocouple 3, the fire outlet 131 corresponding to the thermocouple 3 is a first fire-holding hole 1311, and the first fire-holding hole 1311 is provided with at least two fire-holding holes which are communicated with each other. Since the number of the first fire-holding holes 1311 is not only one, but also communicate with each other, once the overflowing liquid enters one of the first fire-holding holes 1131, the first fire-holding holes 1131 are not blocked. And the annular peripheral wall 12 is further provided with second fire protection holes 1312 communicated with the gas mixing cavity 13 below the first fire protection holes 1311, the second fire protection holes 1312 are provided in two pairs, and the axes of the two second fire protection holes 1312 intersect at an acute angle, so that the second fire protection holes 1312 can be cohered when fire exits, and the fire protection performance of the fire protection holes is ensured.
