[0035] This embodiment discloses a burner and a gas stove including the burner. Specifically, the gas stove includes a table top, and the burner is arranged on the table top. Figures 1 to 8 As shown, the burner includes an outer ring fire cover 1 and a burner head 2, one of which is provided with a positioning protrusion 3, and the other of which is provided with a positioning groove 4, and the positioning protrusion 3 is at least partially embedded in the positioning groove 4.

[0036] When assembling the outer ring fire cover 1 and the burner head 2, the positioning protrusion 3 can be embedded in the positioning groove 4 to align the outer ring fire cover 1 and the burner head 2. Bolts (not shown) and other connecting parts can be more easily inserted into the connecting holes on the outer ring fire cover 1 and the burner head 2. There is no need to manually align the connecting holes, thereby improving assembly efficiency and reducing labor intensity.

[0037] It does not matter which of the positioning protrusion 3 and the positioning groove 4 is arranged on the outer ring fire cover 1 or on the burner head 2, which does not affect the positioning function of the combined structure of the positioning protrusion 3 and the positioning groove 4. Figures 1 to 4 As shown, the positioning protrusion 3 is arranged on the outer ring fire cover 1, and the positioning groove 4 is arranged on the burner head 2. The positioning protrusion 3 includes a protrusion body 31 and a protrusion head 32 connected to each other, the protrusion body 31 is embedded in the positioning groove 4, and the protrusion head 32 is bent relative to the protrusion body 31 toward the center of the burner (inward) and then fits with the burner head 2. That is, the protrusion body 31 and the protrusion head 32 are bent to form an L-shaped structure, and the L-shaped structure hooks the burner head 2 to achieve the fixation of the outer ring fire cover 1 and the burner head 2, and prevent the outer ring fire cover 1 and the burner head 2 from being separated.

[0038] In order to improve the fixing effect, the length of the protrusion body 31 is substantially equal to the length of the positioning groove 4, and the protrusion head 32 can fit tightly on the burner head 2 at the bottom of the positioning groove 4. In this embodiment, an avoidance groove 5 is provided on the burner head 2, and the protrusion head 32 is embedded in the avoidance groove 5. In this structure, the outer surface of the protrusion head 32 does not protrude from the surface of the burner head 2, which does not affect the normal installation of the burner head 2 and other structures, nor does it affect the normal use of the burner head 2.

[0039] The specific setting position and shape of the avoidance groove 5 are not limited, as long as it allows the projection head 32 to be embedded. In this embodiment, the avoidance groove 5 is connected with the positioning groove 4. That is, the positioning groove 4 and the avoidance groove 5 are connected to form an L-shaped structure, and the projection body 31 and the projection head 32 bent into the L shape can be completely embedded in the positioning groove 4 and the avoidance groove 5, which minimizes the increase in the volume of the burner head 2, has a beautiful appearance, and is conducive to the miniaturization design of the burner.

[0040] The specific location and shape of the positioning groove 4 are not limited, as long as it allows the protrusion body 31 to be embedded. In this embodiment, the positioning groove 4 is provided on the outer wall surface of the burner head 2, the protrusion body 31 can be more easily aligned and inserted into the positioning groove 4, and it is easier to design and process the avoidance groove 5, thereby improving the processing efficiency.

[0041] In another structure, such as Figures 5 to 8 As shown, the positioning protrusion 3 is arranged on the burner head 2, and the positioning groove 4 is arranged on the outer ring fire cover 1. During installation, after aligning the positioning protrusion 3 with the positioning groove 4, the outer ring fire cover 1 is pressed down onto the burner head 2, and the alignment and positioning of the outer ring fire cover 1 and the burner head 2 can be completed.

[0042] The specific shape of the positioning protrusion 3 is not limited. In this embodiment, Figures 1 to 8As shown, the head of the positioning protrusion 3 is triangular (pointed) or arc-shaped (rounded). The pointed and rounded structures are conducive to reducing the difficulty of installation. Specifically, during assembly, the positioning protrusion 3 and the positioning groove 4 do not need to be completely aligned. It is only necessary to make the top of the pointed head or the top of the round head of the positioning protrusion 3 be located within the opening range of the positioning groove 4. When the positioning protrusion 3 is pressed down, the head curve of the positioning protrusion 3 will slide along the opening edge of the positioning groove 4, so that the positioning protrusion 3 automatically slides into the positioning groove 4, and the outer ring fire cover 1 and the burner head 2 are aligned.

[0043] The specific number of positioning protrusions 3 and positioning grooves 4 provided on the burner is not limited, as long as the outer ring fire cover 1 and the burner head 2 can be quickly aligned. In order to improve the alignment accuracy, the burner includes at least two positioning protrusions 3 and at least two positioning grooves 4, and one positioning protrusion 3 corresponds to one positioning groove 4.

[0044] All the positioning protrusions 3 are symmetrically distributed relative to the center of the burner, and correspondingly, all the positioning grooves 4 are symmetrically distributed relative to the center of the burner, so that the outer ring fire cover 1 and the burner head 2 are aligned as a whole, avoiding the outer ring fire cover 1 and the burner head 2 being aligned in some areas but not in other areas.

[0045] Regarding "symmetrical distribution relative to the center of the burner", when the number of positioning protrusions 3 (similarly positioning grooves 4) is an even number, two positioning protrusions 3 (similarly positioning grooves 4) are relatively arranged with respect to the center of the burner; when the number of positioning protrusions 3 (similarly positioning grooves 4) is an odd number, the angles between any two adjacent positioning protrusions 3 (similarly positioning grooves 4) are the same, or it is called an equal angle setting.

[0046] In this embodiment, the burner includes three positioning protrusions 3 and three positioning grooves 4, forming three groups of alignment structures. The three positioning protrusions 3 (similarly the three positioning grooves 4) are evenly distributed on the periphery of the burner, and any two adjacent positioning protrusions 3 (similarly the positioning grooves 4) form an angle of 120°.

[0047] In order to improve the assembly efficiency, the outer shape of the positioning protrusion 3 is the same as the inner shape of the positioning groove 4, and the size of the positioning protrusion 3 is less than or equal to the size of the positioning groove 4. The positioning protrusion 3 can be smoothly embedded in the positioning groove 4, and there is no need to force the positioning protrusion 3 into the positioning groove 4 during assembly, which has low labor intensity and saves time and effort.

[0048] Note that the above are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention is described in more detail through the above embodiments, the present invention is not limited to the above embodiments, but may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
