Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
As shown in FIGS. 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, wherein the fire cover body 1 comprises a top wall 11 and an annular peripheral wall 12 extending downwards from the periphery of the top wall 11, main fire holes 121 are formed in the annular peripheral wall 12 at intervals along the circumferential direction, an inner annular wall 13 is arranged on the top wall 11 of the fire cover body 1 at intervals in the inner periphery of the annular peripheral wall 12, a branch flow hole 131 communicated with the main fire holes 121 in a fluid mode is formed in the inner annular wall 13, the inner annular wall 13 is added to form a central branch flow cavity 2, the branch flow cavity 2 reduces the gas flow speed by means of the circulation generated by the rotation of gas flow and the branch flow hole 131, the gas flow speed and the flame combustion speed are helped to reach a balanced state, when the gas pressure is too high, the gas is helped to be divided, and the local speed of a branch flow area is prevented from being too high and the local over-length of flame is avoided.
Specifically, in order to relieve the gas pressure of the cavity surrounded by the annular peripheral wall 12, the inner annular wall 13 divides the cavity surrounded by the annular peripheral wall 12 into the flow dividing cavity 2 located at the center and the outer peripheral cavity 3 located at the periphery of the flow dividing cavity 2, the flow dividing cavity 2 is communicated with the outer peripheral cavity 3 through the flow dividing holes 131, and by adding the inner annular wall 13, the gas rotates in the flow dividing cavity 2 in advance and flows out of the flow dividing holes 131, so that the gas flow rate is reduced, and the gas flow rate and the flame combustion rate can be helped to reach an equilibrium state. Besides the above-mentioned gas diversion through the diversion hole 131, it can also be realized by: the inner annular wall 13 is C-shaped, the annular peripheral wall 12 is provided with a flow divider 4 corresponding to the C-shaped opening 130 of the inner annular wall 13, and the flow divider 4 divides the fuel gas flowing out from the flow dividing cavity 2 enclosed by the inner annular wall 13 through the C-shaped opening 130. The flow dividing piece 4 can help to divide the gas when the gas pressure is too high, so that the local speed of the flow dividing cavity 2 is prevented from being too high and the flame is prevented from being too long locally; the reposition of redundant personnel piece 4 realizes that the gas reposition of redundant personnel that reposition of redundant personnel chamber 2 flowed through C shape opening flows to two directions in, can also regard as the reference column of fire lid, still prevents staying for the fire lid, avoids the fire lid to rotate at will, guarantees that the umbrella of the ignition needle of fire lid is in directly over the ignition needle all the time, guarantees the success rate of igniteing. Finally, in order to improve the combustion fire of the burner fire cover, the main fire holes 121 include a first main fire hole 1211 and a second main fire hole 1212 which are located on the annular peripheral wall 12, and the first main fire hole 1211 and the second main fire hole 1212 are provided, so that a double-row main fire hole 121 is formed, wherein a groove 14 is circumferentially formed between the first main fire hole 1211 and the second main fire hole 1212, the groove 14 intersects the first main fire hole 1211 and/or the second main fire hole 1212, and a pressure stabilizing part formed by the groove 14 is provided between the two rows of main fire holes 121, so that the combustion efficiency of the gas stove can be obviously improved while the first main fire hole 1211 and the second main fire hole 1212 are stabilized.
In order to prevent the first main fire holes 1211 from being out of flame due to the excessively fast air flow in this embodiment, it is preferable that the grooves 14 intersect only with the first main fire holes 1211 without communicating with the second main fire holes 1212, and the first main fire holes 1211 and the second main fire holes 1212 are sequentially arranged in a staggered manner. The groove 14 is only communicated with the first main fire hole 1211 and not communicated with the second main fire hole 1212, on one hand, the gas flowing out from the first main fire hole 1211 can be divided, so that the gas flowing out from the first main fire hole 1211 is slowed down, the combustion is stable, and the gas is not easy to leave the flame; on the other hand, the first main fire holes 1211 and the second main fire holes 1212 are sequentially arranged in a staggered manner, and a circle of flame ring is formed below the first main fire holes 1211 and connected in the groove 14, so that the flame stabilizing effect is exerted on the second main fire holes 1212 in the lower row, and the flame stabilizing effect of the second main fire holes 1212 is good.
