The interface of distributor and the air slot of head fasten, and the fire lid fastens with fuel tank.

Described a kind of internal combustion burner that is used for gas kitchen ranges, its special character is: said fire hole rounded;

Be provided with the fire hole of two groups of rounded distributions on the fire lid internal ring wall vertically, two groups of alternate settings of fire hole; The center line of fire hole and the angle between the horizontal plane are 10 °-30 °.

Described a kind of internal combustion burner that is used for gas kitchen ranges, its special character is: the internal ring wall of said fire lid is the rounding taper type.

Described a kind of internal combustion burner that is used for gas kitchen ranges, its special character is: also comprise a wind deflector, said wind deflector has several air guide holes, and guide plate is fixedly connected with the internal ring wall of the head of burner.

Described a kind of internal combustion burner that is used for gas kitchen ranges, its special character is: also comprise an energy-saving cover, said energy-saving cover comprises inner ring plate, top board and outer shroud cover plate;

There is the level of falling the upper end of the internal ring wall of said fire lid, and the inner ring plate lower surface is supported and cooperated with falling level, and the lower end of outer shroud cover plate cooperates with the support of the circle ring disk of distributor, the connecting hole on the outer shroud cover plate covering circle ring disk.

A kind of internal combustion burner that is used for gas kitchen ranges of the utility model owing to adopt such structure, is assembled during fuel gas buring in the fire lid, and flame is concentrated at the bottom of the heating kettle, improves the thermal efficiency; Auxiliary air gets into from the burner bottom, forms air-flow upwards during fuel gas buring, and the performance pumping function can replenish auxiliary air, sufficient combustion, and toxic emission is few, environmental protection.
