Abstract

A cooker end with fluid fuel, which comprises an external bushing, an internal bushing, an upper cover, a lower bottom, a burner tip for pre-heating and a gasification, corresponding connection pipes and a fuel disc for pre-heating. The cone-shaped internal bushing has double-layer double-wall structure; the cover of the internal bushing is in the shape of cone with flat external top and contracted center; tens of small holes are beveled on the surface of the cone. The cover and the flat circular bottom are sealed and connected by the internal and external bushings; gas collecting cavity is arranged on the surface of the cover; pipes are connected with corresponding cavity rooms; the gasification burner tip is positioned at the lower section of the central internal bushing at the cooker end. The utility model, with simple and compact structure as well as coordinated and scientific layout, would not only realize the quick gasification and efficient combustion of the fuel, but also ensure that the pressures of the fuel case is kept with the safety limit.

Description

Liquid fuel cooker burner

Technical field

The utility model relates to the burner that a kind of cooker of fuel for liquid uses, and is particularly suitable for using for the chafing dish cooker on the dining table.

Background technology

Liquid fuel cooker burner is to improve efficiency of combustion, after the liquid fuel preheating vaporization that all needs to infeed, enters the burning of burner head again.Therefore, burner is except that the need configuration supplies a pre-heating fuel dish that uses, and respective design has liquid fuel gas making chamber and corresponding cavity structure.And the cavity top introducing part boil-off gas of vaporizing certainly is suitable for reading to fuel tank, pours constantly, continues to keep the burner burning with the squeezed fluid fluid fuel through end opening.Be the safety meter, corresponding code requirement is arranged: the pressure in the fuel tank must not be greater than 0.2 MPa.From efficiency of combustion and call for fire, wish that then the vaporization energy of liquid fuel is quick as far as possible on the other hand.Prior art does not also lack perfection in the requirement that solves this a pair of conflicting restriction,

Summary of the invention

The purpose of this utility model is to provide a kind of vaporization combustion fast can satisfy safety standard requirements again, is particularly suitable for the liquid fuel burner that the chafing dish cooker uses.

Technical solution of the present utility model is: burner contains overcoat 1, interior cover 2, loam cake 3, go to the bottom 4, preheating gas making combustion head 5, corresponding connecting pipe 6,7,8 and pre-heating fuel dish (not shown), cover 2 is the double-deck double wall structure of tube taper of upper end reducing in it is characterized in that, loam cake 3 is that peripheral part is flat-top, central portion is the cone structure of downward reducing, evenly be provided with the small perforations of dozens of on central authorities' taper is domatic along the direction of cutting sth. askew, loam cake 3 is bored the existing sealed connection of cause for gossip with the upper end of overcoat 1 and interior cover 2 respectively with its flat-top and the following awl notch portion that contracts, the plane ring-type go to the bottom 4 with its upper surface with in, overcoat 2,1 realizes sealed connection, double-deck double wall cavity constitutes the gas making chamber, loam cake, go to the bottom, in, the space that overcoat surrounds then constitutes the burner chamber, the flat top surface of loam cake 3 is provided with the annular air collecting chamber (9) that the gas making chamber that constitutes through pipeline and interior cover 2 double walls is communicated with, it is suitable for reading that the pipeline 6 of drawing from air collecting chamber 9 causes fuel tank, the fuel tank end opening then is connected with gas making chamber bottom through pipeline (7), introduce by loam cake through valve from the pipeline 8 that air collecting chamber 9 is drawn, go to the bottom, in, overcoat surrounds the burner chamber that the space constitutes, and preheating gas making combustion head 5 is communicated with pipeline 8 behind valve and is set in the burner position under the intracardiac cover.

The beneficial effects of the utility model are: the utility model technical solution mechanism is simple compact, rationally distributed.Particularly overlap 2 in the double-deck double wall structure of tube taper, its upper end convergence be connecting of the main combustion head that constitutes with the outer reamer section of loam cake or with the configuration relation of central lower preheating gas making combustion head 5 all very science coordinate, both helped good flame flow field and formed, also helped and the quick vaporization of heat exchange, promotion in interior cover double wall gas making chamber and the raising of efficiency of combustion.Need only the effectively thickness of control double wall chamber layer simultaneously in the design, inject the fuel quantity of gas making chamber and the firepower of preheating gas making combustion head 5, both just be not difficult to accomplish that vaporization burnt fast, can guarantee that again fuel tank pressure does not exceed standard.The product model machine of making burns through examination, and maximum pressure is about 0.14 MPa in the fuel tank, has realized the purpose of innovation and creation well.

Description of drawings

Accompanying drawing is a structure cross-sectional schematic of the present utility model.

Among the figure: the 1-overcoat, cover, 3-loam cake in the 2-, 4-goes to the bottom, 5-preheating gas making combustion head, 6,7, the 8-pipeline, the 9-air collecting chamber, 10-is subjected to flame tube.

The specific embodiment

Below in conjunction with accompanying drawing the utility model and the specific embodiment thereof are described in further detail.

Referring to accompanying drawing, the utility model contains overcoat 1, interior cover 2, loam cake 3, go to the bottom 4, preheating gas making combustion head 5, corresponding connecting pipe 6,7,8 and the pre-heating fuel dish, cover 2 is the double-deck double wall structure of tube taper of upper end reducing in it is characterized in that, loam cake 3 is that peripheral part is flat-top, central portion is the cone structure of downward reducing, evenly be provided with the small perforations of dozens of on central authorities' taper is domatic along the direction of cutting sth. askew, loam cake 3 with its flat-top and the awl notch portion that contracts down show sealed connection with overcoat 1 and the awl cause for gossip of interior cover 2 upper ends respectively, the plane ring-type go to the bottom 4 with its upper surface with in, overcoat 2,1 realizes sealed connection, the flat top surface of loam cake 3 is provided with the annular air collecting chamber 9 that the gas making chamber that constitutes through pipeline and interior cover 2 double walls is communicated with, it is suitable for reading that the pipeline 6 of drawing from air collecting chamber 9 causes fuel tank, the fuel tank end opening then is connected with gas making chamber bottom through pipeline 7, introduce by loam cake through valve from the pipeline 8 that air collecting chamber 9 is drawn, go to the bottom, in, overcoat surrounds the burner chamber that the space constitutes, and preheating gas making combustion head 5 is communicated with pipeline 8 behind valve and is set in the burner position under the intracardiac cover.
