Another kind of fire lid structure has appeared again in the market in addition, offers out the fire hole on fire lid top and/or the lateral wall, and the flame in the fire lid inner chamber is direct from going out the fire hole blowout, and this kind of processing is simple for traditional structure, but the flame that its formed dashes with strength too big, and steady not live the fire, the energy waste is serious, and combustion effect is poor, still easily blocks up the fire hole during the use, and relatively the processing degree of difficulty is still bigger. Therefore, a fire cover for a gas cooker is provided.

SUMMERY OF THE UTILITY MODEL

The utility model mainly aims to provide a fire cover for a gas cooker, which ensures the effects of fire stabilization and oxygen increasing by arranging a horn-shaped fire stabilizing part and correspondingly forming an angle.

In order to achieve the purpose, the utility model adopts the technical scheme that: the utility model provides a gas cooking utensils are with fire lid, includes fire lid body, go out fire chamber accordant connection on fire lid body and the gas cooking utensils, fire lid body is equipped with main fire hole, main fire hole is including setting up the stable fire portion of horn mouth form at the top, and the chamfer angle alpha that the stable fire portion of horn mouth form formed is 30-120, stable fire portion below is equipped with vice fire hole, vice fire hole and play fire chamber intercommunication.

Further, the main fire hole is integrally columnar.

Furthermore, the end face where the auxiliary fire hole is located is an inclined plane inclined downwards.

Furthermore, the auxiliary fire holes are distributed below the fire stabilizing part at equal intervals, and the auxiliary fire holes are vertically communicated with the fire outlet cavity.

Furthermore, vice fire hole equidistance distributes and in steady fire portion below, and vice fire hole be the inclined hole and with go out the fire chamber intercommunication.

Furthermore, the diameter of the main fire hole is 10-25 mm, and the diameter of the auxiliary fire hole is 1-4 mm.

The gas cooker comprises the fire cover, and the fire cover is connected with the fire outlet cavity in a matched mode.

Compared with the prior art, the utility model has the following beneficial effects:

the flame stabilizing part is arranged in a horn mouth shape, and a chamfer angle formed by the horn mouth shape is beneficial to flame to form a flame stabilizing ring, so that a very good combustion-supporting and flame-stabilizing effect is achieved, the flame is combusted vigorously and stably, the flame combustion utilization rate is high, and the energy is saved and the efficiency is high;

the auxiliary fire hole is arranged below the fire stabilizing part, and a horn-shaped fire stabilizing part is formed to just protect the hole of the auxiliary fire hole, so that sundries are prevented from entering the auxiliary fire hole to cause blockage;

thirdly, the auxiliary fire holes are vertically distributed or obliquely distributed, and only holes are uniformly distributed during processing, so that the processing efficiency of the machine tool is high, the production efficiency is improved, and the production cost of enterprises is saved;

to sum up, the fire lid is through setting up loudspeaker form steady fire portion, and corresponds the angle that forms and guaranteed the effect of steady fire, compares early structural design, and the structure is simpler, and workable, the practicality is strong, has fine spreading value.
