The mesh-type fire cover is supplied with air through the flame stabilizing channel, and the mesh-type fire cover can be better kept to be stably combusted due to the flame stabilizing effect of the flame stabilizing channel.

In order to enable the flame stabilizing channel to have the function of supplying gas to the sinking zone, preferably, the outer ring wall is provided with at least two main fire holes at intervals along the circumferential direction, and each flame stabilizing channel is intersected with the corresponding main fire hole. Because each flame stabilizing channel is arranged in a way of intersecting with the corresponding main fire hole, the mixed gas of the primary air and the fuel gas required by the combustion of the mesh type fire cover can be obtained through the main fire holes.

In order to realize the communication of each flame stabilizing channel to enhance the flame stabilizing effect, preferably, a ring of annular slit is formed on the outer annular wall below each main fire hole, the annular slit is communicated with the lower end of each flame stabilizing channel, and the upper end of each flame stabilizing channel is communicated with the sinking zone.

In order to make the combustion of the mesh type fire cover more uniform, preferably, at least two air outlet holes are arranged at intervals along the circumferential direction of the subsidence area, and each air outlet hole is communicated with the upper end of each flame stabilizing channel. Because the air outlet holes for supplying air to the mesh type fire cover are arranged at intervals along the circumferential direction of the sunken area, uniform combustion can be better performed, and the air outlet holes are communicated with the upper ends of the flame stabilizing channels, so that one-to-one air supply can be performed, and the air supply effect is better.

Compared with the prior art, the utility model has the advantages of: the mesh type fire cover is arranged in the center of the top wall of the burner fire cover for the gas stove, and the gas supply part arranged on the outer annular wall of the fire cover is used for directly supplying gas to the mesh type fire cover, so that a gas supply channel for independently supplying gas to the mesh type fire cover is prevented from being arranged on the inner periphery of the outer annular wall, the difficulty and the cost for manufacturing the fire cover are reduced, and the burner fire cover has the characteristic of easiness in cleaning.

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 burner fire cover for the gas stove comprises a fire cover body 1, wherein the fire cover body 1 comprises a top wall 11, a gas mixing cavity 13 is formed by the top wall 11 and an outer annular wall 12 vertically or obliquely and downwardly extending from the outer edge of the top wall 11, a mesh type fire cover 2 is arranged in the center of the top wall 11, a sinking area 111 for placing the mesh type fire cover 2 is arranged in the center of the top wall 11, correspondingly, the outer annular wall 12 is provided with a gas supply part for supplying gas to the sinking area 111, and the gas supply part is communicated with the gas mixing cavity 13. Because the mesh type fire cover 2 is arranged in the center of the top wall 11 of the burner fire cover for the gas stove, and the gas supply part arranged on the outer annular wall 12 of the fire cover is used for directly supplying gas to the mesh type fire cover 2, the gas supply channel which independently supplies gas to the mesh type fire cover 2 is prevented from being arranged on the inner periphery of the outer annular wall 12, the difficulty and the cost for manufacturing the fire cover are reduced, and the burner fire cover has the characteristic of easy cleaning.

Specifically, in order to realize the combustion stability of the mesh type fire cover 2, the gas supply part of the embodiment is at least two flame stabilizing channels 3 arranged at intervals along the circumferential direction of the outer ring wall 12, the mesh type fire cover 2 is supplied with gas through the flame stabilizing channels 3, and the mesh type fire cover 2 can be better kept in stable combustion due to the flame stabilizing effect of the flame stabilizing channels 3. In order to make the flame holding channels 3 have the function of supplying gas to the sunken zone 111, the outer annular wall 12 is further provided with at least two main fire holes 121 at intervals along the circumferential direction, and each flame holding channel 3 is intersected with the corresponding main fire hole 121. Since each flame stabilizing channel 3 is intersected with the corresponding main fire hole 121, the mixture of primary air and fuel gas required by the combustion of the mesh type fire cover 2 can be obtained through the main fire holes 121.

In addition, a circle of annular slits 122 are formed below each main fire hole 121 on the outer annular wall 12, the annular slits 122 are communicated with the lower end 31 of each flame stabilizing channel 3, the upper end 32 of each flame stabilizing channel 3 is communicated with the sinking region 111, finally, the communication of each flame stabilizing channel 3 is enabled to enhance the flame stabilizing effect, finally, at least two air outlets 112 are circumferentially arranged at intervals on the sinking region 111, each air outlet 112 is communicated with the upper end 32 of each flame stabilizing channel 3, as the air outlets 112 for supplying air to the mesh type fire cover 2 are circumferentially arranged at intervals on the sinking region 111, the uniform combustion can be better performed, and each air outlet 112 is communicated with the upper end 32 of each flame stabilizing channel 3, the air supply can be performed in a one-to-one manner, the air supply effect is better, and the combustion of the mesh type fire cover 2 is more uniform.

To sum up, the burner fire cover for the gas stove obtains the mixed gas of primary air and fuel gas required by the combustion of the mesh-type fire cover 2 by utilizing the flame stabilizing channel 3 intersected with the main fire hole 121, can directly supply gas to the mesh-type fire cover 2 under the condition that the flame stabilizing channel 3 stabilizes the flame of the main fire hole 121, and has the effect of one object and two purposes.
