Detailed Description

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

As shown in fig. 1 to 2, the preferred embodiment of the present invention is shown. The burner fire cover for the gas stove comprises a fire cover body 1, the fire cover body 1 comprises a top wall 11, the top wall 11 and an outer annular wall 12 which extends downwards from the outer edge of the top wall 11 in a vertical or inclined mode form a gas mixing cavity 13, at least two fire outlet holes 121 communicated with the gas mixing cavity 13 are formed in the outer annular wall 12 at intervals along the circumferential direction, at least two protection chambers 2 which are arranged at intervals along the circumferential direction and used for preventing liquid overflowing are arranged on the outer annular wall 12, and each protection chamber 2 corresponds to each fire outlet hole 121 one by one. Each fire hole 121 of this fire lid body 1 has the guard chamber 2 of self independent setting, and this guard chamber 2 can prevent that the discharge from not getting into fire hole 121, plays the effect that prevents the discharge and block up fire hole 121.

Specifically, in order to protect the periphery of each fire hole 121 without affecting the fire of each fire hole 121, the protection chamber 2 of the present embodiment includes a bottom wall directly formed by a part of the outer circumferential wall 12, an outer wall disposed opposite to the bottom wall, and a circumferential wall 21 connecting the bottom wall and the outer wall, and the outer wall is provided with an opening communicated with the fire hole 121. The peripheral wall 21 of the protection chamber 2 surrounds the fire hole 121 to prevent the fire hole 121 from being blocked by the overflowing liquid, and the bottom wall of the protection chamber 2 is directly formed by a part of the outer ring wall 12, so that the protection chamber 2 can be more simply and structurally arranged. In addition, the peripheral wall 21 of the protection chamber 2 further includes a lower peripheral wall 211 located below the fire hole 121, and the lower peripheral wall 211 gradually inclines outward from top to bottom so as to guide the overflowing liquid entering the protection chamber 2.

In order to extend the gas outlet section of each fire hole 121, the wall of each fire hole 121 in this embodiment extends into the gas mixing chamber to form an extension wall 1211. This extension section can lengthen the pore wall of fire outlet 121 to the gas mixture that primary air that the fire outlet 121 flows and gas constitute can realize one section "wall effect of tending", will flow into the overflow of fire outlet 121 when accelerating the gas mixture outflow speed and rush out, play the effect of preventing blocking, and the pore wall of fire outlet 121 to extension wall 1211 all from top to bottom slope inwards gradually, can realize like this that the gas mixture that primary air that the fire outlet 121 flows and gas constitute can flow out from fire outlet 121 more fast, if the overflow that flows into fire outlet 121 also can flow to gas mixing chamber 13 along the pore wall of this fire outlet 121 fast simultaneously, avoid blockking up fire outlet 121.
