It should be noted that, in fig. 2, the outer ring cover 220 is in an inverted state, and the lower ring portion 222 is located below the upper ring portion 221, which is a relative position relationship formed when the outer ring cover 220 is in a normal use state.
In some embodiments, the inner diameter of the upper ring portion 221 is smaller than the inner diameter of the lower ring portion 222, thus forming a step-like structure at the junction of the upper ring portion 221 and the lower ring portion 222. Because outer ring fire lid seat links to each other with lower ring portion 222 through helicitic texture, when outer ring fire lid 200 revolves to outer ring fire lid seat butt this stair structure, outer ring fire lid seat will be blockked, and outer ring fire lid 200 can not be further revolved soon, and this can place outer ring fire lid seat and block fire hole 223, and simultaneously, the user can know in view of the above that outer ring fire lid 200 has revolved soon and has put in place.
An embodiment of the present invention provides a combination structure of a burner and an outer ring fire cover, as shown in fig. 1-5, which includes a burner 100, an outer ring fire cover 200 and a liquid containing tray 300. The burner 100 comprises an ejector tube 110, a burner base 120 connected with the ejector tube 110, and an outer ring burner cap base 130, wherein a gas mixing cavity is arranged in the burner base 120, and the ejector tube 110 is used for ejecting fuel gas to the gas mixing cavity. The stove head base 120 comprises a top disc 121 positioned at the top of the stove head base, the top disc 121 is disc-shaped, and an outer ring opening 122 communicated with the gas mixing cavity is formed in the surface of the top disc 121. The outer ring cap holder 130 is fixed to the upper surface of the top plate 121, and the outer ring opening 122 is located in the outer ring cap holder 130, so that gas is introduced into the outer ring cap holder 130 and finally flows toward the outer ring cap 200.
An external thread 133 is provided on an outer sidewall of the outer ring cap base 130, and an outer diameter of the outer ring cap base 130 is smaller than a diameter of the top plate 121. The liquid containing disc 300 is provided with a central hole 310 penetrating through itself, and the outer diameter of the central hole 310 is smaller than that of the top disc 121 but larger than that of the outer ring fire cover seat 130, so that the outer ring fire cover seat 130 penetrates through the central hole 310, and the top disc 121 supports the liquid containing disc 300.
The outer ring fire cover 200 comprises a top cover 210, an outer ring cover plate 220 and an inner ring cover plate 230, wherein the outer ring cover plate 220 and the inner ring cover plate 230 are both annular and coaxially arranged, and the inner diameter of the outer ring cover plate 220 is larger than that of the inner ring cover plate 230. The top cover 210 is located on top of the outer annular cover plate 220 and the inner annular cover plate 230 and is connected to the outer annular cover plate 220 and the inner annular cover plate 230, specifically, the top cover 210, the outer annular cover plate 220 and the inner annular cover plate 230 may be integrally connected. Thus, the cross-sections of the top cap 210, the outer annular cap 220 and the inner annular cap 230 are shaped like a "U". The top cover 210, the outer ring cover plate 220 and the inner ring cover plate 230 enclose a circulation groove for flowing gas, and after the outer ring fire cover 200 is covered on the outer ring fire cover seat 130, the gas in the outer ring fire cover seat 130 flows into the circulation groove.
The outer ring cover plate 220 includes an upper ring portion 221 and a lower ring portion 222 located below the upper ring portion 221, and the upper ring portion 221 and the lower ring portion 222 are both ring-shaped and connected to each other. The upper ring part 221 is provided with a plurality of fire holes 223 penetrating the upper ring part 221, and the gas in the circulation groove can be jetted and burned through the fire holes 223. The inner side surface of the lower ring part 222 is provided with an internal thread 224 matched with the external thread. The outer ring fire cover 200 is seated on the outer ring fire cover seat 130, and the lower ring part 222 is screw-coupled to the outer ring fire cover seat 130 by the engagement of the external screw 133 and the internal screw 224, thereby combining the outer ring fire cover 200 with the outer ring fire cover seat 130. Meanwhile, the lower ring portion 222 and the top plate 121 clamp and fix the liquid containing plate 300.
Therefore, the outer ring fire cover 200 and the burner 100 are assembled together through the screw structure in the present embodiment, and the screwing operation is simpler, thereby facilitating the assembly and disassembly of the outer ring fire cover 200 and the burner 100. Meanwhile, because the thread structure is hidden, the thread structure is not easy to rust and is still easy to unscrew after long-term use, and the gas stove is convenient for later maintenance.
In some embodiments, an inner fire cover base 140 is fixed on the upper surface of the top plate 121, the inner fire cover base 140 is located inside the outer fire cover base 130, and an inner fire cover 400 is covered on the inner fire cover base 140 to form a double fire cover structure, so that the flame is more uniform.
In some embodiments, the outer ring fire cap seat 130 includes an outer ring plate 131 and an inner ring plate 132 coaxially disposed, the outer ring plate 131 having an inner diameter greater than the inner diameter of the inner ring plate 132 to form a vent slot between the outer ring plate 131 and the inner ring plate 132, the outer ring opening 122 communicating with the vent slot to allow combustion gases to enter the outer ring fire cap seat 130. In this regard, when the outer ring fire cover 200 is assembled with the burner 100, the inner ring cover plate 230 is positioned inside the inner ring plate 132 and closely attached to the inner sidewall of the inner ring plate 132 to enhance the sealing performance and prevent the gas from leaking through the gap between the inner ring cover plate 230 and the inner ring plate 132.
In some embodiments, the inner diameter of the upper ring portion 221 is smaller than the inner diameter of the lower ring portion 222, thus forming a step-like structure at the junction of the upper ring portion 221 and the lower ring portion 222. Since the outer ring fire cover seat 130 is connected with the lower ring part 222 by a screw structure, when the outer ring fire cover 200 is screwed to the outer ring fire cover seat 130 abutting the step structure, the outer ring fire cover seat 130 will be blocked, the outer ring fire cover 200 cannot be screwed further, this can place the outer ring fire cover seat 130 to block the fire hole 223, and at the same time, the user can know from this that the outer ring fire cover 200 has been screwed in place.
In some embodiments, the burner base 120 and the outer ring fire cover base 130 are integrally connected, which not only enhances the structural strength of the connection between the burner base 120 and the outer ring fire cover base 130, but also simplifies the manufacturing process of the burner base 120 and the outer ring fire cover base 130.
In some embodiments, the two sides of the burner base 120 are provided with support legs 150, and the support legs 150 can be fixed on the gas stove by screws, so that the burner 100 can be kept stable.
The foregoing is a more detailed description of the present invention that is presented in conjunction with specific embodiments, and the practice of the utility model is not to be considered limited to those descriptions. It will be apparent to those skilled in the art that a number of simple derivations or substitutions can be made without departing from the inventive concept.
