[0028] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Various examples are provided by way of explanation of the present invention and not by way of limitation. In fact, those skilled in the art will recognize that modifications and variations can be made to the present invention without departing from the scope or spirit of the invention. For example, a feature shown or described as part of one embodiment may be used in another embodiment to produce yet another embodiment. Therefore, it is desirable that the present invention encompass such modifications and variations that fall within the scope of the appended claims and their equivalents.

[0029] In the description of this utility model, the terms "first," "second," and similar words do not indicate any order, quantity, or importance, but are only used to distinguish different components. Words such as "comprising" or "including" mean that the element or object preceding the word covers the element or object listed after the word and its equivalents, without excluding other elements or objects. Terms such as "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," and "bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and do not require that this utility model be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this utility model. The terms "connected," "linked," and "set up" used in this utility model should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a direct connection or an indirect connection through intermediate components; a wired connection, a radio connection, or a wireless communication signal connection. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

For clarity, the following definitions are provided. Figure 2 The upper part is called "upper" and the lower part is called "lower". The side wall of the main body 1 is provided with a main flame hole 3 and a flame stabilizing hole 4. The main flame hole 3 penetrates the side wall of the main body 1, and the top of the flame stabilizing hole 4 is located inside the side wall of the main body 1. The flame stabilizing hole 4 communicates with the flame stabilizing groove 2, and the top of the flame stabilizing hole 4 is higher than the top surface of the flame stabilizing groove 2.

[0031] The buffered flame cap provided in this embodiment of the invention has interconnected flame-stabilizing holes 4 and flame-stabilizing grooves 2.

Figure 4 , Figure 5 As shown, in one embodiment of this utility model, the main flame hole 3 is connected to the flame stabilizing groove 2. Specifically, the connecting area between the flame stabilizing groove 2 and the main flame hole 3 is one-quarter of the cross-sectional area of ​​the main flame hole 3. For example, the diameter of the main flame hole 3 is 2.6 mm, and the cross-sectional area of ​​a single main flame hole 3 is 5.3 mm. 2 The area of ​​connection between the two is 1.32 mm. 2 .

[0034] like Figures 2-5 As shown, in one embodiment of this utility model, the axial direction of the main flame hole 3 forms a first angle with the horizontal direction, and the axial direction of the flame stabilizing hole 4 forms a second angle with the horizontal direction. Further, the degree of both the first and second angles is 30-45 degrees. Preferably, the degree of the first angle is 38 degrees.

[0035] In one embodiment of this utility model, the width of the flame stabilizing groove 2 is in the range of 0.6-1.2mm, and more preferably, the width of the flame stabilizing groove 2 is 0.8mm.

[0036] In the above embodiments, the flame cap can be directly used as the outer flame cap of the burner. In another embodiment of the present invention, the top of the body 1 is provided with a cover plate (not shown in the figure), which closes the top of the body 1 and can be used as the inner flame cap of the burner.

[0037] This invention also provides a burner including the aforementioned fire cap with a buffer. Furthermore, the fire cap can be used as an outer fire cap or an inner fire cap. The burner also includes other necessary components, such as a base, an ejector tube, a nozzle, etc., which are prior art and will not be described in detail here.

[0038] This utility model also provides a cooktop, including the aforementioned burner. This cooktop can be a gas stove, an integrated stove, etc., which can improve the product's applicability to different regions and gas sources, and enhance combustion stability.

[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
