Description

Technical Field

[0001] This application relates to the field of stove technology, and in particular to a burner cap and a gas stove. Background Technology

[0002] The burner cap of a gas stove refers to the cap located in the center of the burner. It covers the outlet of the inner ring gas nozzle and the inner ring ejector / mixing tube below, forming a relatively closed gas-air premixing chamber, from which the gas is directionally ejected through the flame holes. Existing burner caps have flame holes on the top or side. This presents the following problems:

[0003] When cooking, spilled soup, water, or other liquids from the pot can easily drip directly onto or near the flame vents of a single-layer burner cap. If the liquid flows into or blocks the flame vents, it will instantly extinguish the flame, creating a significant safety hazard of gas leakage and interrupting the cooking process.

[0004] To address these issues, some flame covers have been fitted with raised eaves or waterproof trays. However, these designs are often simple in structure and offer poor protection against liquids that drip or splash vertically onto the center of the flame cover. Utility Model Content

[0005] This application aims to provide a burner cap and gas stove that are both waterproof and have flame-stabilizing functions.

[0006] This application provides a fire cover, including a main structural part, a first eaves part, and a second eaves part;

[0007] The peripheral wall of the main structure has a main fire hole and a flame stabilizing groove, which are arranged along the axial direction of the fire cap.

[0008] Along the axial direction of the flame cap, the first protruding part is located on the side of the main flame hole away from the flame stabilizing groove. The first protruding part is used to block the liquid from the side of the first protruding part away from the main flame hole from flowing to the main flame hole. The second protruding part is located between the main flame hole and the flame stabilizing groove. The second protruding part is used to block the liquid from the side of the second protruding part away from the flame stabilizing groove from flowing to the flame stabilizing groove.

[0009] The burner cap according to the embodiments of this application has at least the following beneficial effects: By providing a first and a second protruding eave, the burner cap, which includes a main burner hole and a flame stabilizing groove, improves the stability of gas stove combustion and the efficiency of gas combustion through the flame stabilizing groove. Simultaneously, the first and second protruding eaves reduce the possibility of liquid flowing into the burner cap through the main burner hole and flame stabilizing groove due to their placement, thus providing both waterproofing and flame stabilization functions.

[0010] According to some embodiments of this application, the projection of the first eaves portion and the portion of the main structure portion where the first eaves portion is located along the axial direction of the flame cover covers the projection of the portion of the main structure portion where the main flame hole is located along the axial direction of the flame cover; and / or,

[0011] The projection of the second eaves and the portion of the main structure where the second eaves are located along the axial direction of the flame cap covers the projection of the portion of the main structure where the flame stabilizing groove is located along the axial direction of the flame cap.

[0012] In this embodiment, by projecting the first eaves and the portion of the main structure where the first eaves are located along the axial direction of the flame cap onto the portion of the main structure where the main flame hole is located along the axial direction of the flame cap, the first eaves, being above the main flame hole and completely blocking the portion of the main flame hole, prevents liquid dripping from the main flame hole. Similarly, by projecting the second eaves and the portion of the main structure where the second eaves are located along the axial direction of the flame cap onto the portion of the main structure where the flame stabilizing groove is located along the axial direction of the flame cap, the second eaves, being above the opening of the flame stabilizing groove and completely blocking the portion of the opening of the flame stabilizing groove, prevents liquid dripping from the flame stabilizing groove.

[0013] According to some embodiments of this application, along the radial direction of the flame cap, the distance between the outer edge of the first convex portion and the outer end of the main flame hole is d1, and the distance between the outer edge of the second convex portion and the opening of the flame stabilizing groove is d2.

[0014] Wherein, 0.25mm≤d1≤3mm; and / or, 0.25mm≤d2≤3mm.

[0015] In this embodiment, the outer edge radius of the first protruding part is larger than the outer end radius of the main flame hole. This ensures that the first protruding part can completely cover the main flame hole below. By ensuring that the difference d1 between the outer edge radius of the first protruding part and the outer end radius of the main flame hole is 0.25mm≤d1≤3mm, it can not only block liquids dripping or splashing from above, but also avoid the problem that the difference between the outer edge radius of the first protruding part and the outer end radius of the main flame hole is too large, which would cause the first protruding part to block the rising flame, affect the heating of the cookware above the burner, and reduce the combustion efficiency. Similarly, the outer edge radius of the second protrusion is larger than the opening radius of the flame stabilizing groove. This ensures that the second protrusion can completely cover the opening of the flame stabilizing groove below. By ensuring that the difference d2 between the outer edge radius of the second protrusion and the radius of the flame stabilizing groove is 0.25mm≤d2≤3mm, it can block liquids dripping or splashing from above. At the same time, it can also prevent the difference between the outer edge radius of the second protrusion and the radius of the flame stabilizing groove from being too large, which would cause the second protrusion to block the rising flame, affect the heating of the cookware above the burner, and reduce the combustion efficiency.

[0016] According to some embodiments of this application, along the axial direction of the flame cap, the distance between the first convex portion and the outer end of the main flame hole is d3, and the distance between the second convex portion and the groove of the flame stabilizer groove is d4.

[0017] Where 0.2mm≤d3≤4mm; and / or 0.2mm≤d4≤4mm.

[0018] In this embodiment, the vertical distance d3 between the first protruding part and the outer end of the main flame hole satisfies 0.2mm≤d3≤4mm, which enables optimal waterproofing and flame stabilization. Similarly, the distance d4 between the second protruding part and the opening of the flame stabilization groove satisfies 0.2mm≤d4≤4mm, which also enables optimal waterproofing and flame stabilization.

[0019] According to some embodiments of this application, at least one of the first and second convex portions surrounds the main structure portion around the circumference of the fire cover.

[0020] In this embodiment, the first and second convex portions can each be a complete annular strip structure, thus forming a complete shielding strip that can block liquid flowing down from various angles at the top of the main structure.

[0021] According to some embodiments of this application, a first inclined structure is provided on the side of the first eaves away from the main fire hole, the first inclined structure being used to guide liquid on it to the outer edge of the first eaves; and / or,

[0022] The second eaves has a second inclined structure on the side away from the flame stabilizer groove. The second inclined structure is used to guide the liquid on it to the outer edge of the second eaves.

[0023] In this embodiment, by providing a first inclined structure on the side of the first eaves away from the main flame hole, the liquid on the upper surface of the first eaves can be guided to flow away along the outer edge of the inclined surface, preventing liquid from accumulating on the first eaves. Similarly, by providing a second inclined structure on the side of the second eaves away from the flame stabilizer groove, the liquid on the upper surface of the second eaves can be guided to flow away along the outer edge of the inclined surface, preventing liquid from accumulating on the second eaves.

[0024] According to some embodiments of this application, the angle between the first inclined structure and the reference plane is a1, the angle between the second inclined structure and the reference plane is a2, and the reference plane is a plane perpendicular to the axis of the flame cap.

[0025] Where 25°≤a1≤75°; and / or 25°≤a2≤75°.

[0026] In this embodiment, by ensuring that the angle α1 between the first inclined structure and the reference plane satisfies 25°≤a1≤75°, the liquid on the upper surface of the first protrusion can flow smoothly downwards while preventing the liquid from flowing downwards at an excessively high velocity, thus avoiding splashing. Similarly, by ensuring that the angle α2 between the second inclined structure and the reference plane satisfies 25°≤a2≤75°, the liquid on the upper surface of the second protrusion can flow smoothly downwards while preventing the liquid from flowing downwards at an excessively high velocity, thus avoiding splashing.

[0027] According to some embodiments of this application, the first convex portion and the second convex portion are disposed opposite each other along the axial direction of the fire cover.

[0028] In this embodiment, the first eaves and the second eaves are arranged opposite to each other. Specifically, the first eaves are located directly above the second eaves. The first eaves can block the liquid flowing down from the main fire hole and also block the liquid flowing down from the second eaves below. This can reduce the possibility of liquid dripping onto the second eaves and thus reduce the possibility of liquid flowing into the flame stabilizer.

[0029] According to some embodiments of this application, the end face of the main structure located on the side of the main fire hole away from the flame stabilizer groove has a flow guide groove;

[0030] The wall of the guide channel has an overflow port, which is connected to the inner cavity of the guide channel. The overflow port is also connected to the space on the side of the first protrusion away from the main fire hole. The guide channel is used to guide the liquid in the guide channel to the overflow port.

[0031] In this embodiment, a guide channel is provided on the end face of the main structure located away from the flame stabilizer slot, specifically on the top of the main structure. This allows liquid dripping onto the top of the main structure to collect in the guide channel and flow away from the overflow port. Through the guiding effect of the guide channel and the overflow port, the liquid flows away in a specific direction, preventing it from flowing away from all directions on the top of the main structure and causing splashing. Simultaneously, a corresponding first protrusion is provided in the outlet direction of the overflow port to block the liquid flowing out of the overflow port.

[0032] This application also discloses a gas stove, including the aforementioned burner cap.

[0033] The gas stove according to the embodiments of this application has at least the following beneficial effects: while meeting the requirements for waterproofing, it also has the function of stabilizing the flame. Attached Figure Description

[0048] In existing technology, to improve the combustion efficiency of gas stoves, main burner holes and flame stabilizing grooves are arranged along the axial direction of the burner cap as flame outlets. The flame stabilizing grooves and flame stabilizing holes are connected, and the flame stabilizing holes are relatively smaller than the main burner holes. The flame stabilizing grooves improve flame stability. Generally, there are multiple main burner holes arranged along the perimeter of the burner cap, with the main burner holes and flame stabilizing grooves arranged vertically. However, the increase in the number of flame stabilizing grooves also increases the possibility of liquid flowing into the burner cap from the main burner holes or flame stabilizing grooves.

[0049] Therefore, refer to Figure 1 As shown, this application discloses a fire cap, including a main structural part 100, a first convex part 200, and a second convex part 300;

[0050] The peripheral wall of the main structure 100 has a main fire hole 101 and a flame stabilizer groove 102, and the main fire hole 101 and the flame stabilizer groove 102 are arranged axially.

[0051] Along the axial direction of the burner cap, a first protruding portion 200 is provided on the side of the main burner hole 101 away from the flame stabilizer groove 102. The first protruding portion 200 is used to block the liquid from the side of the first protruding portion 200 away from the main burner hole 101 from flowing to the main burner hole 101. A second protruding portion 300 is provided between the main burner hole 101 and the flame stabilizer groove 102. The second protruding portion 300 is used to block the liquid from the side of the second protruding portion 300 away from the flame stabilizer groove 102 from flowing to the flame stabilizer groove 102.

[0052] In this embodiment, the peripheral wall of the main structure 100 has a main flame hole 101 and a flame stabilizing groove 102, which are arranged along the axial direction of the flame cap. The flame stabilizing groove 102 can improve the stability of the flame, thereby improving the combustion efficiency of the gas. Simultaneously, by providing a first eaves 200 and a second eaves 300 above the main flame hole 101 and above the flame stabilizing groove 102 respectively, the first eaves 200 blocks liquid flowing down from above the main flame hole 101, preventing liquid from entering the main flame hole 101. Similarly, the second eaves 300 blocks liquid flowing down from above the flame stabilizing groove 102, preventing liquid from entering the flame stabilizing groove 102. In this embodiment, "above" refers to the top of the flame cap and the bottom of the flame cap, and is not intended as a specific limitation.

[0053] In some embodiments, the first eaves 200 and the second eaves 300 may also be configured to enclose the main flame hole 101 and the flame stabilizing groove 102, respectively, thus preventing liquid from entering the main flame hole 101 and the flame stabilizing groove 102. Furthermore, any structural configuration in which the first eaves 200 and the second eaves 300 can prevent external liquid from entering the main flame hole 101 and the flame stabilizing groove 102 should fall within the scope of protection of this application.

[0054] By providing the first eaves 200 and the second eaves 300, the burner cap, which includes the main burner hole 101 and the flame stabilizing groove 102, improves the stability and efficiency of gas combustion. Simultaneously, the first eaves 200 and the second eaves 300 reduce the likelihood of liquid flowing into the burner cap through the main burner hole 101 and the flame stabilizing groove 102. This achieves both waterproofing and flame stabilization functions, reducing the possibility of foreign matter accumulating and clogging the main burner hole 101 and the flame stabilizing groove 102 due to liquid inflow.

[0055] In some embodiments of this application, the projection of the first eaves 200 and the portion of the main structure 100 where the first eaves 200 is located along the axial direction of the flame cap covers the projection of the portion of the main structure 100 where the main flame hole 101 is located along the axial direction of the flame cap; and / or,

[0056] The projection of the second eaves 300 and the portion of the main structure 100 where the second eaves 300 is located along the axial direction of the flame cap covers the projection of the portion of the main structure 100 where the flame stabilizer groove 102 is located along the axial direction of the flame cap.

[0057] In this embodiment, by having the projection of the first eaves 200 and the portion of the main structure 100 where the first eaves 200 is located along the axial direction of the flame cap cover the projection of the portion of the main structure 100 where the main flame hole 101 is located along the axial direction of the flame cap, the first eaves 200 is positioned above the main flame hole 101 and completely blocks the portion of the main flame hole 101's outer end, thus preventing liquid dripping from above the main flame hole 101. Alternatively, a portion of the main structure 100 and the first eaves 200 may together block the portion of the main flame hole 101's outer end.

[0058] Similarly, the projection of the second eaves 300 and the portion of the main structure 100 where the second eaves 300 is located along the axial direction of the flame cap covers the projection of the portion of the main structure 100 where the flame stabilizing groove 102 is located along the axial direction of the flame cap. Thus, the second eaves 300 is above the opening of the flame stabilizing groove 102 and completely blocks the outer end of the opening of the flame stabilizing groove 102, thereby blocking the liquid dripping from above the flame stabilizing groove 102. Alternatively, a portion of the main structure 100 and the second eaves 300 may together block the opening of the flame stabilizing groove 102.

[0059] In some embodiments of this application, along the radial direction of the flame cap, the distance between the outer edge of the first convex portion 200 and the outer end of the main flame hole 101 is d1, and the distance between the outer edge of the second convex portion 300 and the opening of the flame stabilizing groove 102 is d2.

[0060] Wherein, 0.25mm≤d1≤3mm; and / or, 0.25mm≤d2≤3mm.

[0061] refer to Figure 2 and Figure 3As shown, in this embodiment, the outer edge radius of the first protruding eave 200 is larger than the outer end radius of the main flame hole 101. This ensures that the first protruding eave 200 can completely cover the main flame hole 101 below. By ensuring that the difference d1 between the outer edge of the first protruding eave 200 and the outer end of the main flame hole 101 satisfies 0.25mm≤d1≤3mm, it can not only block liquids dripping or splashing from above, but also avoid the problem that the distance difference between the outer edge of the first protruding eave 200 and the outer end of the main flame hole 101 is too large, causing the first protruding eave 200 to block the rising flames, affecting the heating of the cookware above the burner, and resulting in reduced combustion efficiency.

[0062] Similarly, the outer edge radius of the second protruding part 300 is larger than the groove radius of the flame stabilizing groove 102. This ensures that the second protruding part 300 can completely cover the groove of the flame stabilizing groove 102 below. By ensuring that the difference d2 between the outer edge of the second protruding part 300 and the flame stabilizing groove 102 is 0.25mm≤d2≤3mm, it can block liquids dripping or splashing from above. At the same time, it can also avoid the problem that the difference in distance between the outer edge of the second protruding part 300 and the flame stabilizing groove 102 is too large, which would cause the second protruding part 300 to block the rising flame, affect the heating of the cookware above the burner, and reduce the combustion efficiency.

[0063] The outer edges of the first eaves 200 and the second eaves 300 can have various shapes, such as straight edges, slightly rolled-up / turned-down edges, or serrated edges, to facilitate the smooth dripping or drainage of liquid on the first eaves 200 and the second eaves 300.

[0064] If the vertical distance between the first eaves 200 and the outer end of the main fire hole 101, and the vertical distance between the second eaves 300 and the opening of the flame stabilizing groove 102 are too large, the waterproof and flame stabilizing effects will be weakened.

[0065] Therefore, in some embodiments of this application, along the axial direction of the flame cap, the distance between the first convex portion 200 and the outer end of the main flame hole 101 is d3, and the distance between the second convex portion 300 and the groove of the flame stabilizer 102 is d4.

[0066] Where 0.2mm≤d3≤4mm; and / or 0.2mm≤d4≤4mm.

[0067] refer to Figure 2 and Figure 3 As shown, in this embodiment, the vertical distance d3 between the first eaves 200 and the outer end of the main fire hole 101 satisfies 0.2mm≤d3≤4mm, which enables the waterproofing and flame stabilization to achieve the optimal effect.

[0068] Similarly, the distance d4 between the second eaves 300 and the groove of the flame stabilizing groove 102 satisfies 0.2mm≤d4≤4mm, which enables the waterproofing and flame stabilization to achieve the best effect.

[0069] In some embodiments of this application, at least one of the first convex portion 200 and the second convex portion 300 surrounds the main structure portion 100 around the circumference of the fire cover.

[0070] refer to Figure 1 As shown, the first convex portion 200 and the second convex portion 300 can each be a complete annular strip structure, thus forming a complete shielding strip that can block liquid flowing down from various angles at the top of the main structure portion 100.

[0071] In some embodiments, the first eaves 200 and the second eaves 300 may also be provided only at corresponding positions above the main flame hole 101 and the flame stabilizer 102. This can also serve to block liquid flowing down from the top of the main structure 100 and prevent it from entering the main flame hole 101 and the flame stabilizer 102.

[0072] In some embodiments of this application, a first inclined structure 201 is provided on the side of the first eaves 200 away from the main flame hole 101. The first inclined structure 201 is used to guide liquid on it to the outer edge of the first eaves 200; and / or,

[0073] The second eaves 300 is provided with a second inclined structure 301 on the side away from the flame stabilizer 102. The second inclined structure 301 is used to guide the liquid on it to the outer edge of the second eaves 300.

[0074] refer to Figure 2 As shown, by providing a first inclined structure 201 on the side of the first eaves 200 away from the main fire hole 101, the liquid on the upper surface of the first eaves 200 can be guided to flow away along the outer edge of the inclined surface under the action of the first inclined structure 201, thus preventing the liquid from accumulating on the first eaves 200.

[0075] Similarly, by providing a second inclined structure 301 on the side of the second eaves 300 away from the flame stabilizer 102, the liquid on the upper surface of the second eaves 300 is guided to flow away along the outer edge of the inclined surface under the action of the second inclined structure 301, so as to avoid the liquid accumulating on the second eaves 300.

[0076] The first inclined structure 201 and the second inclined structure 301 are generally straight inclined surfaces, but they can also be inclined structures that can guide the liquid to flow away, such as inclined grooves and inclined holes.

[0077] In some embodiments of this application, the angle between the first inclined structure 201 and the reference plane is a1, the angle between the second inclined structure 301 and the reference plane is a2, and the reference plane is a plane perpendicular to the axis of the flame cap.

[0078] Where 25°≤a1≤75°; and / or 25°≤a2≤75°.

[0079] refer to Figure 2 As shown, by ensuring that the angle a1 between the first inclined structure 201 and the reference plane satisfies 25°≤a1≤75°, the liquid on the upper surface of the first protrusion 200 can flow smoothly downwards while avoiding excessive downward flow velocity of the liquid, which would cause the liquid to splash everywhere.

[0080] Similarly, by ensuring that the angle a2 between the second inclined structure 301 and the reference plane satisfies 25°≤a2≤75°, the liquid on the upper surface of the second eaves 300 can flow smoothly downwards while avoiding excessive downward flow velocity that could cause the liquid to splash everywhere.

[0081] In some embodiments of this application, the first convex portion 200 and the second convex portion 300 are disposed opposite each other along the axial direction of the fire cap.

[0082] refer to Figures 1 to 3 As shown, the first protruding part 200 and the second protruding part 300 are arranged opposite to each other. Specifically, the first protruding part 200 is located directly above the second protruding part 300. The first protruding part 200 can block the liquid flowing down from the main flame hole 101 and also block the liquid flowing down from the second protruding part 300 below. This can reduce the possibility of liquid dripping onto the second protruding part 300, thereby reducing the possibility of liquid flowing into the flame stabilizer 102.

[0083] In some embodiments of this application, the end face of the main structure located on the side of the main fire hole 101 away from the flame stabilizer 102 has a guide groove 103;

[0084] The wall of the guide channel 103 has an overflow port 104, which is connected to the inner cavity of the guide channel 103. The overflow port 104 is also connected to the space on the side of the first protrusion 200 away from the main fire hole 101. The guide channel 103 is used to guide the liquid in the guide channel 103 to the overflow port 104.

[0085] refer to Figure 1 and Figure 4As shown, in this embodiment, a guide groove 103 is provided on the end face of the main structure located on the side away from the flame stabilizer 102 of the main flame hole 101. Specifically, the guide groove 103 is provided on the top of the main structure, so that liquid dripping onto the top of the main structure can gather in the guide groove 103 and flow away from the overflow port 104. Through the guiding effect of the guide groove 103 and the overflow port 104, the liquid flows away in a specific direction, instead of flowing away from all directions on the top of the main structure, causing the liquid to splash everywhere. At the same time, a corresponding first protrusion 200 is provided in the outlet direction of the overflow port 104 to block the liquid flowing out of the overflow port 104.

[0086] In some embodiments, there may be one or more overflow ports 104. In this embodiment, two overflow ports 104 are preferably provided and are arranged opposite to each other on both sides of the guide groove 103.

[0087] The flame cap of this application has a simple structure, can be machined by turning, is easy to produce and assemble, and has a low cost.

[0088] This application also discloses a gas stove, including the aforementioned burner cap.

[0089] A gas stove is a kitchen appliance that uses liquefied petroleum gas, manufactured gas, natural gas, or other gaseous fuels for direct-fire heating. The burner cap is located in the center of the burner and covers the outlet of the inner ring gas nozzle and the inner ring ejector / mixing pipe below. Since the gas stove of this application adopts all the technical solutions of the burner cap of the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0090] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
