In addition, the fire-blocking skirt can prevent the heat of the outer ring mixing chamber from being directly transferred to the air inlet end of the ejector tube, thereby achieving the effect of heat insulation.

Description

Technical Field

[0001] The utility model relates to the technical field of burners, in particular to a rotary fire burner capable of preventing oil pollution from seeping in. Background Art

[0002] The burner head is an important component of the gas cooker, which generally includes an outer ring ejector pipe, an outer ring gas mixing chamber, an outer ring gas outlet groove, an outer ring fire cover, an inner ring ejector pipe, an inner ring gas mixing chamber, an inner ring gas outlet groove and an inner ring fire cover.

[0003] Among them, the rotary fire burner usually sets the outer ring fire cover in an inverted cone structure, and sets a strip-shaped fire outlet hole on the inner surface to form a rotary fire-shaped combustion flame. However, the long strip-shaped fire outlet hole is easy for oil to directly penetrate into the interior of the burner head, blocking the fire hole or the ejector tube, affecting the smoothness of the gas supply, so further improvement is needed. In addition, the heat of the outer ring mixing chamber is easily transferred directly to the air inlet end of the ejector tube, thereby affecting the working stability of the valve body and the control element. Therefore, further improvement is needed. Utility Model Content

[0027] Example

[0028] Reference Figures 1 to 4The utility model provides a rotary fire burner with oil-proof infiltration function, comprising an outer ring ejector pipe 10, an outer ring gas mixing chamber 20 and an outer ring gas outlet groove 30 connected in sequence, and an inner ring ejector pipe 40, an inner ring gas mixing chamber 50 and an inner ring gas outlet groove 60 connected in sequence; an outer ring fire cover 70 is installed on the outer ring gas outlet groove 30, and an inner ring fire cover 80 is installed on the inner ring gas outlet groove 60;

[0029] The top of the outer ring fire cover 70 is provided with an inverted cone-shaped outer ring top surface 71, and the outer ring top surface 71 is provided with a plurality of upwardly protruding fire bosses 72 at intervals along the circumferential direction, and the fire bosses 72 are extended with fire grooves 73; a fire-blocking skirt 90 is provided below the side of the outer ring mixing chamber 20 facing the outer ring ejector tube 10.

[0030] In the utility model, the top of the outer ring fire cover 70 is provided with an inverted cone-shaped outer ring top surface 71, and a plurality of fire outlet bosses 72 are arranged at intervals along the circumferential direction, and a fire outlet groove 73 is extended on the fire outlet boss 72 to form a rotating fire-shaped burning flame. In the utility model, the fire outlet groove 73 is arranged on the upward convex fire outlet boss 72, and the oil and water stains dripping from the cooking utensils above the fire cover will flow toward the outer edge of the fire boss and the outer edge of the fire cover, and are not easy to penetrate into the fire outlet groove 73, effectively preventing oil stains from penetrating into the interior of the burner, and can ensure the cleanliness of the internal space of the burner. In addition, the fire-blocking skirt 90 can prevent the heat of the outer ring mixing chamber 20 from being directly transferred to the air inlet end of the ejector tube, and play a role in heat insulation.

[0031] In this embodiment, in order to achieve a uniform rotary fire outer ring air supply structure, a plurality of fire outlet bosses 72 are evenly spaced along the circumferential direction and arranged on the outer ring top surface 71 .

[0032] In this embodiment, the outer ring fire cover 70 is formed by stamping a metal sheet; the fire outlet boss 72 is a boss structure formed by stamping the outer ring top surface 71 upward.

[0033] Specifically, the fire-out boss 72 is further punched upward to form a second boss 74; the second boss 74 is broken along one side of the outer ring top surface 71 in the circumferential direction to form an opening structure to form a fire-out groove 73. There is no need to cut the fire-out groove 73 structure; only one side of the second boss 74 is cut off when punching the fire-out boss 72 and the second boss 74 when punching the outer ring fire cover 70, so as to form the fire-out structure, and the processing technology is simple and reliable.

[0034] In this embodiment, the outer ring fire cover 70 is tightly mounted on the inner and outer peripheries of the fire outlet groove 73. The fire cover structure made of sheet metal pressing has a certain deformation ability and can be fixedly installed on the inner and outer edges of the fire outlet groove 73 by pressing.

[0035] In this embodiment, in order to allow the gas to be more smoothly delivered from the ejector tube to the gas mixing chamber and diffused in the circumferential direction of the gas mixing chamber, an outer ring inclined flow guide chamber 11 is provided between the outer ring ejector tube 10 and the outer ring gas mixing chamber 20; an inner ring inclined flow guide chamber 41 is provided between the inner ring ejector tube 40 and the inner ring gas mixing chamber 50.

[0036] Specifically, the outlet end of the outer ring inclined flow guide cavity 11 is arranged in a flared trumpet-shaped structure; the outlet end is provided with a diverter baffle 21. Since the area of ​​the outer ring mixing cavity 20 is large, the diverter baffle 21 can partially block the gas from being directly sent from the outer ring ejector pipe 10 to the outer ring fire cover 70, but diffuses it laterally to various areas of the outer ring mixing cavity 20, and then sent to the outer ring fire cover 70.

[0037] Furthermore, the outlet end of the inner ring inclined flow guide cavity 41 is bifurcated in a U-shape, and can supply gas to both sides of the inner ring gas mixing cavity 50. The inner ring gas can be evenly delivered to both sides of the inner ring gas mixing cavity 50 through the inner ring inclined flow guide cavity 41 bifurcated in a U-shape.

[0038] Of course, the present invention is not limited to the above-mentioned embodiments, and technicians familiar with the field may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications and substitutions are all included in the scope defined by the claims of this application.
