Technical field
The present invention relates to a kind of burners, more particularly, to a kind of cooker burner.
Background technique
Currently, household cooking utensil burner is more using the form of tricyclic, three fire-ring stove burners big, firepower with firepower
More uniform advantage is suitble to quick-fried and stewes slowly.But existing three fire-ring stove burner when switching firepower from outermost
Circle inwardly gradually switches, and needs there are three the cooperation of the valve body in channel, and the valve body price in general three channels is higher, also, each
Fire cover fire hole intensity corresponding to channel is not identical, is easy to produce tempering and detonation phenomenon when switching firepower.In addition, center
Firepower is generally smaller, and fire hole is also smaller, and fire cover hole is easy to block up, and fire cover hole plug will cause inside combustion gas reflux meeting kitchen range,
Certain concentration is gathered, may early cause deflagration phenomenon, there are security risks.As Patent No. 200620066644.1 (is awarded
Disclosed " improved kitchen range tricyclic stove head " described in Chinese utility model patent of the power notification number for CN 200986186Y), should
Burner includes fire cover seat, furnace head base and ejector pipe, which uses three ejector pipes, and outer ring air flue in fire cover seat, in
Ring air flue and central flame air flue separate and are connected respectively with two main ejector pipes and center ejector pipe.Although the tricyclic stove head
In use, primary air when burning can be made to supplement sufficiently, each ring flame controls respectively, still, is still unable to improve
The switching of triple channel firepower, or the phenomenon not uniform enough there are three ring firepowers.In conclusion needing to existing cooker burner
Structure is further improved.
Summary of the invention
The technical problem to be solved by the present invention is to be directed to above-mentioned state of the art, triple channel firepower can be improved by, which providing, is cut
