[0025] The utility model provides the following description with reference to the accompanying drawings to help fully understand the various embodiments of the utility model as defined by the claims and their equivalents. The description includes various specific details to help understanding, but these details should be regarded as exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the utility model.

[0026] In the description of the present invention, descriptions of orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0027] It will be understood that when one element (eg, a first element) is “connected” to another element (eg, a second element), the element may be directly connected to the other element or an intervening element (eg, a third element) may be present between the element and the other element.

[0028] The embodiment of the utility model provides an integrated fire cover, such as Figure 1 and Figure 2As shown, it includes a middle ring fire cover 110 and a center fire cover 120. The center fire cover 120 is arranged on the top surface of the middle ring fire cover 110 and is integrally connected with the middle ring fire cover 110. Specifically, the middle ring fire cover 110 and the center fire cover 120 can be integrally cast. Thus, the middle ring fire cover 110 and the center fire cover 120 form an integrated fire cover structure. It only needs to assemble the entire integrated fire cover to the burner, and the middle ring fire cover 110 and the center fire cover 120 are assembled in place, which facilitates the overall assembly.

[0029] The outer side of the middle ring fire cover 110 is provided with a plurality of middle ring fire holes 111 penetrating the middle ring fire cover. After the mixed gas is ejected through the middle ring fire holes 111 and ignited, a middle ring flame is formed. The inner side of the middle ring fire cover 110 is provided with a central insert tube 130 extending downward. The outer side of the middle fire cover 120 is provided with a plurality of middle fire holes 121. The middle fire holes 121 penetrate the inner side wall of the central insert tube 130. The central insert tube 130 is provided to separate the central channel for supplying the mixed gas to the middle fire holes 121 and the middle ring channel for supplying the mixed gas to the middle ring fire holes 111, so that the central channel and the middle ring channel form two independent channels that do not interfere with each other. When the mixed gas is ejected through the middle fire hole 121 and ignited, a middle flame is formed. At the same time, the outer diameter of the middle fire cover 120 is smaller than the outer diameter of the middle ring fire cover 110, so that the central fire hole 121 is located on the inner side of the middle ring fire hole 111 to ensure that the central flame and the middle ring flame can be formed.

[0030] In this embodiment, the middle ring fire cover 110 and the center fire cover 120 can both be cylindrical, the middle ring fire holes 111 can be arranged on the outer circumference of the middle ring fire cover 110 , and the center fire holes 121 can be arranged on the outer circumference of the center fire cover 120 .

[0031] In some embodiments, the outer circumference of the top surface of the central ring fire cover 110 is provided with a first baffle ring 112 protruding upward, and the outer circumference of the top surface of the central fire cover 120 is provided with a second baffle ring 122 protruding upward, the first baffle ring 112 is provided with a first notch 113, and the second baffle ring 122 is provided with a second notch 123. The first baffle ring 112 can prevent liquids such as oil, water, or soup on the top surface of the central ring fire cover 110 from diffusing to the surroundings, and only flow out through the first notch 113, thereby reducing the risk of most central ring fire holes 111 being blocked. The second baffle ring 122 can prevent liquids such as oil, water, or soup on the top surface of the central fire cover 120 from diffusing to the surroundings, and only flow out through the second notch 123, thereby reducing the risk of most central fire holes 121 being blocked.

[0032] Furthermore, the radial direction of the first notch 113 relative to the center fire cover 110 is parallel to the radial direction of the second notch 123 relative to the center fire cover 120. The first notch 113 is closer to the second notch 123. After the liquid flows out from the second notch 123, it can flow out from the first notch 113 as soon as possible to avoid accumulation on the top surface of the center fire cover 110.

[0033] In some embodiments, a downwardly extending positioning plate 140 is fixed to the bottom surface of the center ring fire cover 110, a positioning piece can be set on the gas distribution plate of the burner, and a positioning slot can be set on the top surface of the positioning piece. When assembling the integrated fire cover of this embodiment, the positioning plate 140 is inserted into the positioning slot to position the assembly of the center ring fire cover 110 so that the entire integrated fire cover can be accurately assembled to the burner.

[0034] The positioning plug plate 140 can be fixed on the bottom surface of the outer peripheral wall of the middle ring fire cover 110, and the positioning plug plate 140 is easier to be inserted into the positioning slot.

[0035] In some embodiments, the middle ring fire cover 110, the center fire cover 120 and the center insert 130 are all coaxially arranged, the overall layout is more regular, the corresponding gas mixing chambers can be evenly distributed relative to the central axis, and the pressure distribution in the gas mixing chamber is more uniform, which helps to maintain a uniform flame. Of course, the middle ring fire holes 111 can be evenly distributed on the middle ring fire cover 110, and the center fire holes 121 can also be evenly distributed on the center fire cover 120 to improve the uniformity of the flame.

[0036] The embodiment of the utility model provides a gas stove capable of stir-frying. Figure 3-5 As shown, it includes a burner head 200, an air distribution plate 300 arranged on the burner head 200, an outer ring fire cover 150, an outer ring air intake pipeline 410, a middle ring air intake pipeline 420, a stir-fry pipeline 430 and an integrated fire cover of any of the above embodiments. The specific description of the integrated fire cover can be referred to the above embodiments and will not be repeated here.

[0037] The gas distribution plate 300 can be fixed on the top surface of the burner head 200. The top surface of the gas distribution plate 300 is provided with an outer convex ring 310, a middle ring gas mixing pipe 320 and a central gas mixing pipe 330. The middle ring gas mixing pipe 320 is located on the inner side of the outer convex ring 310, and the central gas mixing pipe 330 is located on the inner side of the middle ring gas mixing pipe 320. The outer convex ring 310, the middle ring gas mixing pipe 320 and the central gas mixing pipe 330 can be coaxially arranged. The outer ring fire cover 150 is covered on the outer convex ring 310, and the outer ring fire cover 150 and the outer convex ring 310 enclose an outer ring gas mixing cavity 311. The outer ring fire cover 150 is provided with an outer ring fire hole, and the outer ring fire hole is connected to the outer ring gas mixing cavity 311. The middle ring fire cover 110 is covered on the middle ring gas mixing pipe 320, and the middle ring fire hole is connected to the inner cavity of the middle ring gas mixing pipe 320. The central insert pipe 130 is connected to the central gas mixing pipe 330, and the central fire hole is connected to the inner cavity of the central gas mixing pipe 330. At the same time, the cavity between the central gas mixing pipe 330 and the middle ring gas mixing pipe 320 and the cavity inside the central gas mixing pipe 330 are separated by the central insert pipe 130 and the central gas mixing pipe 330 connected to each other, forming two independent cavities, which do not interfere with each other and do not affect each other's gas flow. The outer ring air intake pipeline 410 is connected to the outer ring gas mixing chamber 311 to supply a mixed gas of gas and air to the outer ring gas mixing chamber 311, and the mixed gas is then ejected from the outer ring fire hole, and after ignition, an outer ring flame is formed. The middle ring air intake pipeline 420 is connected to the middle ring gas mixing pipe 320 to supply a mixed gas of gas and air to the middle ring gas mixing pipe 320, and the mixed gas is then ejected from the middle ring fire hole, and after ignition, a middle ring flame is formed. The stir-fry pipeline 430 is connected to the central gas mixing pipe 330 to supply a mixture of gas and air to the central gas mixing pipe 330. The mixed gas is then ejected from the central fire hole and ignited to form a central flame, which can increase the firepower and achieve stir-frying. At the same time, since the central ring fire and the central fire are supplied by two independent airways, they do not interfere with each other, which can increase the heat load of the central flame. After the stir-fry pipeline 430 stops supplying gas, the central ring flame will not be affected and can maintain normal combustion.

[0038] In this embodiment, the central cannula 130 can be inserted into the central mixing tube 330 , or the central mixing tube 330 can be inserted into the central cannula 130 , or the end surfaces of the central cannula 130 and the central mixing tube 330 abut against each other to achieve docking between the central cannula 130 and the central mixing tube 330 .

[0039] In some embodiments, a positioning piece 340 is provided on the inner side of the center ring mixing pipe 320, and a positioning slot 341 is provided on the top surface of the positioning piece 340. When the integrated fire cover is assembled on the gas distribution plate 300, the positioning plug plate on the bottom surface of the center ring fire cover 110 is inserted into the positioning slot 341 to position the assembly of the center ring fire cover 110 so that the entire integrated fire cover can be accurately assembled on the gas distribution plate 300.

[0040] In some embodiments, the outer circumferential surface of the outer convex ring 310 is provided with a plurality of air supplement channels 312 penetrating to the inner circumferential surface of the outer convex ring 310. The air supplement channels 312 and the outer ring mixing chamber 311 are independent of each other. External air can enter the inner side of the outer convex ring 310 through the air supplement channels 312 to supplement secondary air to the middle ring flame and the center flame so that the gas can be fully burned.

[0041] In some embodiments, a solenoid valve 431 for controlling the opening of the stir-frying pipeline 430 is provided in the stir-frying pipeline 430. The solenoid valve 431 can control the stir-frying pipeline 430 to be turned on or off to supply gas to the middle ring mixing pipe 320 or stop the gas, thereby controlling whether the burner forms a two-ring flame or a three-ring flame for stir-frying.

[0042] In some embodiments, a thermocouple 210 is also fixed on the gas distribution plate 300, and the thermocouple 210 is located on the outside of the middle ring fire cover 110. The first notch of the above embodiment is far away from the thermocouple 210 to prevent liquid from flowing to the thermocouple 210 and causing the thermocouple 210 to malfunction.
