Description
Technical field
The utility model relates to burner and combustion gas tool technical field, relates in particular to the buffer-type combustion gas tool flame export device that can make high pressure mixed gas smooth combustion.
Background technology
Along with people's living standard improve constantly, kitchen guarding's electrical equipment has been come into huge numbers of families, has become one of daily necessities indispensable in the people life.By people are known, gas-cooker, gas heater and various gas furnace all are to obtain heat by the burning combustible gas, and whether its burning fully directly determines utilization efficiency of energy.The flame export structure of existing burner and combustion gas tool is directly to burn on the gas outlet of different shape and formation flame, near port, there are not other buffering and protective device, the burning gases of this structure mostly are nature premix air Mixture, and optional pressure-air gaseous mixture, inner oxygen content is enough inabundant, so its burning is still enough inabundant; When the more air of combustible gas Forced Mixing, the gaseous mixture internal pressure is increased, and the air velocity that makes the gas outlet come out is accelerated, and the flame when this moment, this structure was burnt can break away from burner because of high velocity air, formation is from flame or take off fiery phenomenon, causes burning more insufficient; Thereby cause the waste loss of the energy.So the flame export that has burner and combustion gas tool now is carried out structure of modification to be necessary and the space in fact.
The utility model content
The purpose of this utility model is to provide a kind of structure to arrange rationally, can effectively improve the buffer-type flame export device of efficiency of energy utilization at defective and deficiency in the existing combustion gas tool flame export structure.
For achieving the above object, the utility model is by the following technical solutions:
The utility model buffer-type combustion gas tool flame export device comprises combustion chamber, gas outlet, block piece; Described combustion chamber is the semi-surrounding chamber that is made of the chamber wall, and described chamber wall comprises all internal faces of combustion chamber inside; Outlet when described gas outlet is gas fuel burning, with UNICOM of combustion gas tool internal mix gas chamber, described gas outlet penetrates the chamber wall and outlet is positioned at combustion chamber inside; Described block piece is air-flow or the flame flow obstacle that is positioned at the dead ahead, gas outlet, described block piece comprises baffle element and ennation, described baffle element is arranged on the airflow direction of gas outlet, the face relative with the gas outlet is blocking surface on the described baffle element, described blocking surface is positioned at combustion chamber inside, described ennation and chamber wall are connected to form support, and described block piece is provided with through hole or the space forms passage of flame.
Further, integrated buffer formula combustion gas tool flame export device is made up of several combustion chambers, and described combustion chamber inside is provided with several gas outlets, is provided with block piece on the airflow direction of each gas outlet accordingly.
Further, the area of described gas outlet is less than the area of the blocking surface that is arranged on the corresponding baffle element in dead ahead, and the gas outlet parallel projection on the airflow direction in the area on the blocking surface all in blocking surface.
Further, described blocking surface integral body is perpendicular to the airflow direction of gas outlet.
Further, when described chamber wall is positioned on the airflow direction of gas outlet, can omit block piece, the chamber wall namely becomes block piece.
Further, described combustion chamber can be interconnected amalgamation and constitute by the surface of different parts, and described chamber wall can be interconnected amalgamation and form by the some between the different parts.
Further, described block piece and chamber wall can adopt integrative-structure.
The utility model beneficial effect is: the utility model comprises combustion chamber, gas outlet and block piece, and block piece and combustion chamber become creative parts of the present invention.The high pressure combustible gas that the is mixed with more air back of coming out from the gas outlet forms high velocity air, if in air-flow the place ahead block piece is not set this moment, can not smooth combustion even light, and flame can be dispelled in atmospheric environment by high velocity air; The utility model is provided with block piece in the dead ahead, gas outlet; after the high velocity air that comes out or flame flow run into baffle element; make bluster stream along blocking surface change direction and to diffusion all around; this process has reduced air velocity and concentration degree largely; after the bluster stream after the diffusion runs into chamber wall around the combustion chamber, can change direction again and underspeed; this moment, the chamber of semi-surrounding cut off external environment condition; play protection and stablize the effect of inner bluster stream; make bluster stream block piece in the chamber form smooth combustion with passage of flame between the wall of chamber, and at the exit of combustion chamber formation direct injection flame.This result combines more oxygen when making the combustible gas burning, has realized completing combustion, and has effectively improved ignition temperature.Thereby improve efficiency of energy utilization greatly.
