Burner cap for gas stove

Abstract

The invention relates to a burner cap for a gas stove. The burner cap comprises an upper cap body, a gas mixing cavity is formed between the annular top wall of the upper cap body and an inner annularwall and an outer annular wall which vertically or obliquely extend downwards from the inner side edge and the outer side edge of the annular top wall, and a transverse ignition hole is formed in theupper cap body in the radial direction. The bottom of the transverse ignition hole is provided with a gas inlet hole communicated with the gas mixing cavity, an opening at the inner side of the transverse ignition hole is located in the inner annular wall, and an opening at the outer side of the transverse ignition hole is located in the outer ring wall. The burner cap is characterized in that anignition channel crossed with the transverse ignition hole is further included, and comprises an ignition outlet formed in the annular top wall and a first gas supplementing channel independent of the transverse ignition hole and communicating with the ignition channel. Compared with the prior art, the burner cap has the advantage that the phenomenon of fire transfer failure is not prone to occurring.

Description

technical field [0001] The invention relates to a burner for a household stove, in particular to a fire cover for a gas stove. Background technique [0002] At present, most of the traditional burner fire caps sold on the market are milled with one groove, that is, there is a fire ignition groove milled on the top of the upper cover body. Disconnection, thus easily causing deformation of the upper cover, thereby affecting the effect of ignition. For example, the Chinese utility model patent "Gas burner with fire transmission device and flameout protection function" whose patent number is 201220464214.0 (announcement number is CN202813375U) discloses a similar fire transmission structure. Outer ring fire injection hole, and the outer ring fire transmission device is also provided on the outer ring fire injection hole, the outer ring fire transmission device is a boss installed on the inner wall of the outer ring fire injection ring, set on the The outer ring fire transmissi...

Problems solved by technology

[0003] For this reason, a Chinese invention patent application whose application number is CN201710901140.X (publication number is CN107461744A) discloses a fire cover, which has a chute, wherein the chute can communicate with the fire transmission hole and the outside world, which is conducive to fire transmission. The air in the hole circulates, so that the fire hole has enough air to support the flame burning in the fire hole, and the first shielding part and the second shielding part on both sides of the chute can prevent the water droplets in the combustion environment from directly dripping into the fire The hole or cross wind blowing through the fire hole will cause the fire hole to lose the function of fire transmission, but if the chute is completely blocked by the overflow, as the chute that can connect the fire hole and the outside world will cause the fire transmission of the fire hole Ineffective, for this reason it is necessary to further improve the fire transmission structure of the existing burner
