[0039] Reference Figure 1-Figure 10 , is an embodiment of the gas stove of the utility model.

[0040] The gas stove comprises a burner and a pot support frame 200 surrounding the outer side of the burner. The burner comprises a burner head assembly and a fire cover assembly 100 arranged on the burner head assembly.

[0041] The fire cover assembly 100 includes a fire cover seat 110, an inner ring fire cover 120 disposed above the fire cover seat 110, and an outer ring fire cover 130. The outer ring fire cover 130 is disposed around the outer side of the inner ring fire cover 120.

[0042] like Figure 6 and Figure 7 As shown, the fire cover assembly has an inner ring air mixing channel a and an outer ring air mixing channel b which are independent of each other.

[0043] The inner ring fire cover 120 is provided with an inner ring fire hole 112 , and the inner ring fire hole 112 is communicated with the inner ring gas mixing channel a.

[0044] The outer ring fire cover 130 has a circle of fire grooves 133 that penetrate through its outer ring wall, and the fire grooves 133 are connected to the outer ring gas mixing channel b. The outer ring fire cover 130 is an integral structure, and the fire grooves 133 are turning grooves processed by turning technology.

[0045] The fire groove 133 divides the outer ring fire cover 130 into an upper fire cover portion 131 and a lower fire cover portion 132 .

[0046] See also Fig.10A plurality of upper connecting parts 134 are arranged inside the fire groove 133, and the plurality of upper connecting parts 134 connect the upper fire cover part 131 and the lower fire cover part 132. At the same time, the upper connecting parts 134 divide the fire groove 133 into multiple sections of fire outlet areas and fire avoidance areas. That is, the part of the fire groove 133 not blocked by the upper connecting parts 134 forms the fire outlet area, and the part blocked by the upper connecting parts 134 forms the fire avoidance area.

[0047] See also Fig. 9 The fire cover seat 110 is provided with a corresponding upper connecting portion 134 and a lower connecting portion 111. The upper connecting portion 134 and the lower connecting portion 111 are fixedly connected to fix the outer ring fire cover 130 and the fire cover seat 110 together.

[0048] like Figure 1 and Figure 4 As shown, the pot support frame 200 surrounds the outer side of the fire cover assembly 100, and the pot support frame 200 includes a bottom ring 210 and a plurality of support ears 220 disposed on the bottom ring 210. Each support ear 220 is disposed close to the fire avoidance area formed on the outer ring fire cover 130. That is, each support ear 220 corresponds to the upper connecting portion 134 on the outer ring fire cover 130 and is located on the outer side of the upper connecting portion 134. Figure 8 As shown, each support ear 220 corresponds to each lower connecting portion 111 of the fire cover seat (the lower connecting portion 11 corresponds to the upper connecting portion 134 one by one).

[0049] In the above-mentioned gas stove, the outer ring fire cover 130 is an integrated structure, and the fire groove 133 is processed by turning. Its structure is simple, and the groove-shaped flame can effectively contact the bottom of the pot, and the heating is more uniform; at the same time, the upper connecting part 134 connecting the upper and lower parts of the outer ring fire cover 130 not only plays a connecting role, but also forms a fire avoidance space, reducing the heating of the pot support 200 by the flame, reducing the carbon monoxide emissions of the combustion system, reducing heat loss, and improving thermal efficiency.

[0050] In this embodiment, the upper connecting portion 134 and the lower connecting portion 111 are fixedly connected by fasteners. The fasteners may be screws, bolts, etc. In other embodiments, the upper connecting portion 134 and the lower connecting portion 111 may be fixedly connected by welding or the like.

[0051] Specifically, Fig. 9 and Fig.10 As shown, the upper connecting portion 134 is a columnar structure connected to the outer ring wall of the outer ring fire cover, and a threaded hole is provided at its center; that is, the upper connecting portion 134 is a screw column with a threaded hole 1341, and the lower connecting portion 111 is provided with a step mounting hole 1111 that passes through the fire cover seat 110, and a fastener (not shown in the figure) can pass through the step mounting hole 1111 and be threadedly connected to the screw column, as shown in FIG. Figure 5 .

[0052] In this embodiment, the number of the upper connecting parts 134 and the supporting ears 220 of the pot support frame 200 is equal and corresponds one to one, and can be set to 2, 3, 4, etc.

[0053] The upper connecting portion 134 is evenly distributed along the circumference of the outer ring fire cover 130, which is conducive to the flame of the outer ring fire cover 130 burning evenly along the circumference, thereby uniformly heating the pot. At the same time, the support ears 220 are evenly distributed along the circumference of the bottom ring 210 of the pot support frame 200.

[0054] See also Fig.10 The inner side surface of the outer ring wall of the outer ring fire cover 130 protrudes inward to form an upper connecting portion 134; that is, the upper connecting portion 134 is connected to the outer ring wall of the outer ring fire cover 130 as a whole, which is convenient for processing and manufacturing.

[0055] See also Fig. 9 The inner side surface of the outer ring wall of the fire cover seat 110 is convex inward to form a lower connecting portion 111. That is, the lower connecting portion 111 is connected to the outer ring wall of the fire cover seat 110 as a whole, which is convenient for processing and manufacturing.

[0056] In this embodiment, the width of the fire groove 133 is in the range of 1-3 mm, preferably 1.5 mm.

[0057] The fire groove 133 is arranged upwardly and tilted from inside to outside along the outer ring wall of the outer ring fire cover 130. The tilt angle of the fire groove 133 is in the range of 30-50°, preferably 40°, which can ensure that the flame of the outer ring fire cover 130 has a good heat exchange effect with the bottom of the pot.

[0058] The fire groove 133 is arranged near the top of the outer ring wall of the outer ring fire cover 130. The fire groove 133 is arranged near the top surface of the outer ring fire cover 130, which is convenient for turning processing and manufacturing.

[0059] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the above embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the above embodiments, or to replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions claimed to be protected by the present invention.
