In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0039] like Figures 1 to 6 As shown, an assembly structure of a burner center fire cover of the utility model comprises a center fire cover 1 and a burner head 2. The burner head 2 is provided with a center fire cover seat 201 for assembling the center fire cover 1.

[0040] The assembly structure further comprises a clamping member 101 and an elastic member 3, wherein the clamping member 101 is fixed to the central fire cover 1. The clamping member 101 is in a long strip shape.

[0041] The elastic member 3 is detachably connected to the central fire cover seat 201; the elastic member 3 is preferably a spring. The elastic member 3 specifically includes two straight rods 301, which are connected by a second arc segment 306, each straight rod 301 is provided with a V-shaped rod 302, and the other ends of the two straight rods 301 are respectively connected to a clamping section 303 through a first arc segment 304, and the ends of the clamping sections 303 are vertically connected to a positioning rod 305 downward. The straight rod 301, the second arc segment 306, the V-shaped rod 302, the first arc segment 304, the clamping section 303 and the positioning rod 305 are an integrated structure, which is convenient for overall disassembly and assembly.

[0042] By rotating the center fire cover 1, the clamping member 101 is driven to rotate and clamped to the elastic member 3, so as to realize the positioning and fixation between the center fire cover 1 and the burner head 2; through the design of the above structure, not only the connection stability and reliability between the center fire cover 1 and the burner head 2 can be improved, but also the installation and disassembly are convenient and quick, and the center fire cover 1 is not easy to fall off or be misplaced during transportation.

[0043] The clamping piece 101 is provided with two oppositely arranged notches 102, and the elastic piece 3 includes two parallel straight rods 301. The center fire cover 1 drives the notches 102 to rotate along the straight rods 301 through the clamping piece 101, thereby realizing the assembly between the center fire cover 1 and the elastic piece 3, which is beneficial to the fixed connection of the center fire cover 1 and convenient and quick disassembly and assembly.

[0044] The notch 102 is provided with an inclined surface 103. The center fire cover 1 drives the clamping part 101 to rotate until the inclined surface 103 contacts the straight rod 301, so that the elastic part 3 pre-tightens the clamping part 101. When the center fire cover 1 drives the clamping part 101 to rotate, the inclined surface 103 is used for guiding. After rotating to the desired position, it can form a manager with the elastic part 3, which is not only beneficial to compacting the center fire cover 1, but also beneficial to sealing, thereby improving the connection stability.

[0045] A V-shaped rod 302 is provided on the straight rod 301, and a contact surface 104 is provided on the clamping piece 101 below the notch 102. The center fire cover 1 drives the contact surface 104 to rotate through the clamping piece 101, so that the contact surface 104 is against the V-shaped rod 302, thereby positioning the center fire cover 1 and improving the connection stability between the clamping piece 101 and the elastic piece 3.

[0046] The V-shaped rod 302 includes an integrally formed limiting section 302a, a third arc section 302c and an inclined section 302b. The limiting section 302a is connected to the inclined section 302b via the third arc section 302c. The limiting section 302a is used to abut against the contact surface 104 to fix the center fire cover 1. The limiting section 302a is vertically connected to the straight rod 301, which is beneficial to fix the clamping part 101.

[0047] The center fire cover seat 201 is provided with an annular groove 205, and a second arc segment 306 is provided between two adjacent straight rods 301. The second arc segment 306 is limited to the annular groove 205 to achieve axial positioning of the elastic member 3, thereby preventing the clamping member 101 from moving after being inserted into the elastic member 3, thereby improving the stability and reliability of the installation of the center fire cover 1.

[0048] The straight rod 301 is connected to the clamping section 303 through the first arc section 304. The clamping section 303 is limited to the annular clamping groove 205 to achieve axial positioning of the elastic member 3, prevent the clamping member 101 from moving after being clamped into the elastic member 3, and improve the stability and reliability of the installation of the center fire cover 1.

[0049] The central fire cover seat 201 is provided with a central fire dividing chamber 202, and the inner wall of the central fire dividing chamber 202 is provided with a positioning protruding ring 203. Two positioning blocks 204 are circumferentially provided in the central fire dividing chamber 202, and the positioning blocks 204 are located above the positioning protruding ring 203. The clamping section 303 is connected with a positioning rod 305, and the positioning rod 305 abuts against the positioning block 204, so as to realize circumferential positioning of the elastic member 3 and improve the stability when the clamping member 101 is connected to the elastic member 3.

[0050] When the utility model is actually used, the center fire cover is first placed vertically, the clamping piece is aligned with the two straight rods on the elastic piece and is placed between the two straight rods, and then the center fire cover is rotated to make the clamping piece rotate between the two straight rods. The straight rod passes through the gap horizontally, and the inclined surface at the bottom of the gap has a guiding effect, which cooperates with the elastic piece to form a certain pre-tightening force. The clamping piece is continued to be rotated until the V-shaped rod abuts against the contact surface of the bottom side of the clamping piece, and the clamping piece is pressed to realize the positioning and fixation between the center fire cover and the burner head.

[0051] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to achieve basically the same technical effects are all included in the protection scope of the present invention.
