Description

Burner for gas stove
Technical Field
the invention relates to a burner, in particular to a fire cover structure with a good fire protection effect.
Background
A common household burner generally has an outer fire cover and an inner fire cover, and together with an ignition needle, a thermocouple (or an ion sensing needle with the same function), and other elements, realizes the functions of generating flame, maintaining flame, and the like. The outer fire lid structure of current combustor generally covers the body including the outer fire that has a plurality of main fire passageways, and outer fire covers body lower terminal surface and has the gas mixing chamber, should mix gas chamber and main fire passageway intercommunication, and main fire passageway forms main fire hole at the outer terminal surface of outer fire lid body. Such patent documents refer to a conical fire cover for a gas stove burner (publication number CN2842216Y) in chinese utility model patent No. ZL200520014838.2, and refer to a burner fire cover (publication number CN202149492U) in chinese utility model patent No. ZL 201120246965.0. The single main fire hole combustion method disclosed above has disadvantages that the flame is likely to jump after combustion and the combustion area is unstable. A plurality of outer fire cover structures with flame stabilizing functions are disclosed in the prior art, for example, the Chinese utility model patent with the patent number ZL200920112857.7 (the patent number of the authorized bulletin is CN201377835Y) discloses an outer fire cover of a gas stove, wherein flame stabilizing holes are arranged on the vertical surface of the outer side of the outer fire cover, the flame stabilizing holes are positioned below the outer fire holes and are alternately arranged with the outer fire holes, and the inner ends of the flame stabilizing holes are communicated with a gas channel of the fire cover. Due to the arrangement of the flame stabilizing holes, the combustion efficiency is greatly improved, and the emission of carbon monoxide in a room can be reduced. However, the overflow liquid easily enters the main fire hole or the flame stabilizing hole to block the main fire channel or the flame stabilizing channel, and the gas stove is not ignited when the blocked fire hole corresponds to the vicinity of the ignition needle, and the gas stove cannot maintain the flame when the blocked fire hole corresponds to the vicinity of the thermocouple (or the ion induction needle with the same function).
