[0032] Unless otherwise defined, all terms (including technical terms and scientific terms) used herein have the same meanings as those generally understood by those skilled in the art to which the various embodiments of the present invention belong. The terms (such as those defined in generally used dictionaries) will be interpreted as having the same meanings as the contextual meanings in the relevant technical field and will not be interpreted as having idealized meanings or overly formal meanings unless clearly defined in the various embodiments of the present invention.

[0033] like Figure 1-5 As shown, in one embodiment, the utility model provides a burner, including a fire cover assembly 1, the fire cover assembly 1 includes an upper cover 10, an adjusting member and a base 13; the upper cover 10 is covered on the base 13, the adjusting member is arranged between the upper cover 10 and the base 13, and is respectively abutted against the upper cover 10 and the base 13 so that the upper cover 10 and the base 13 are spaced apart to form a fire hole 14, and the adjusting member is used to adjust the distance between the upper cover 10 and the base 13 to adjust the width of the fire hole 14.

[0034] On the basis of the above structure, when in use, the upper cover 10 is covered on the base 13, the base 13 is placed on the burner head 4, and the adjusting member is arranged between the upper cover 10 and the base 13 so that the upper cover 10 and the base 13 are spaced apart to form an annular fire hole 14 arranged around the outer periphery of the upper cover 10 and the base 13. When the gas source pressure is large or the heat load is large, the distance between the upper cover 10 and the base 13 is increased by adjusting the adjusting member so that the width of the fire hole 14 can be adjusted to increase to meet the use requirements of large gas source pressure or large heat load; when the gas source pressure is small or the heat load is small, the distance between the upper cover 10 and the base 13 is reduced by adjusting the adjusting member so that the width of the fire hole 14 can be adjusted to decrease to meet the use requirements of small gas source pressure or small heat load. Therefore, this burner is suitable for the use requirements of different types of gas sources and heat loads, and has good versatility.

[0035] Specifically, in this embodiment, Figure 2 As shown, the adjusting member is an adjusting washer 11, and the adjusting washer 11 is arranged around the upper cover 10 and the base 13; the adjusting washer 11 is provided with at least two groups of adjusting parts, and the adjusting parts include at least two adjusting bosses 110 of different heights, and the adjusting bosses 110 of the same height in each group of the adjusting parts are respectively abutted against the upper cover 10 and the base 13; in this way, the adjusting washer 11 has a relatively simple structure, and by rotating the adjusting washer 11, the adjusting bosses 110 of different heights are selected in the adjusting parts to abut against the upper cover 10 and the base 13 respectively to adjust the distance between the upper cover 10 and the base 13, thereby adjusting the width of the fire hole 14, and therefore it is suitable for the use requirements of different types of gas sources and heat loads.

[0036] Exemplarily, when the gas source pressure is relatively large or the heat load is relatively large, the adjusting washer 11 is rotated to make the adjusting boss 110 with a higher height in the adjusting part respectively abut against the upper cover 10 and the base 13, so that the distance between the upper cover 10 and the base 13 is increased, thereby the width of the fire hole 14 can be adjusted to increase to meet the use requirements of relatively large gas source pressure or relatively large heat load; when the gas source pressure is relatively small or the heat load is relatively small, the adjusting washer 11 is rotated to make the adjusting boss 110 with a lower height in the adjusting part respectively abut against the upper cover 10 and the base 13, so that the distance between the upper cover 10 and the base 13 is reduced, thereby the width of the fire hole 14 can be adjusted to decrease to meet the use requirements of relatively small gas source pressure or relatively small heat load.

[0037] In order to improve the stability of the upper cover 10 being placed on the base 13 , in this embodiment, every two adjusting portions are arranged oppositely on two sides of the adjusting washer 11 .

[0038] Furthermore, in this embodiment, if Figure 3-4 As shown, the upper cover 10 is provided with at least two first positioning flanges 100, and the base 13 is provided with at least two second positioning flanges 130, and the adjustment bosses 110 of the same height in each group of the adjustment parts are respectively abutted against the first positioning flanges 100 and the second positioning flanges 130; such a configuration, on the one hand, improves the accuracy of selecting the adjustment bosses 110 of different heights, and on the other hand, improves the supporting stability between the adjustment bosses 110 and the upper cover 10 and the base 13 respectively.

[0039] Furthermore, in this embodiment, the number of the adjustment parts, the first positioning flanges 100 and the second positioning flanges 130 are all four, each group of the adjustment parts is evenly distributed on the adjustment gasket, each first positioning flange 100 is evenly distributed on the upper cover 10, and each second positioning flange 130 is evenly distributed on the base 13, and the adjustment bosses 110 of the same height in each group of the adjustment parts are respectively abutted against the first positioning flange 100 and the second positioning flange 130, thereby further improving the supporting stability between the adjustment bosses 110 and the upper cover 10 and the base 13.

[0040] In this embodiment, if Figure 1As shown, the burner also includes a threaded connector 2, the first positioning flange 100 is provided with a threaded hole 1000, the second positioning flange 130 is provided with a through hole 1300, the threaded connector 2 passes through the through hole 1300 and is threadedly connected to the threaded hole 1000, so that the upper cover 10, the adjusting member 11 and the base 13 are pressed against each other. The advantage of such a design is that the connection stability between the upper cover 10, the adjusting member 11 and the base 13 is improved, and the upper cover 10, the adjusting member 11 and the base 13 are prevented from shifting relative to each other during the assembly process or use of the burner, causing abnormal operation of the burner.

[0041] It should be noted that the threaded connector 2 can be a screw, a bolt, etc., which is not limited here.

[0042] Furthermore, in this embodiment, if Figure 2 As shown, the adjusting boss 110 is provided with a positioning groove 1100, and the two ends of the positioning groove 1100 penetrate through one end face of the adjusting boss 110 and the other end face of the adjusting boss 110; the two ends of the positioning groove 1100 are respectively arranged corresponding to the threaded hole 1000 and the through hole 1300. The advantage of such a design is to avoid the displacement of the adjusting gasket during the assembly process or use of the burner, and at the same time improve the accuracy of the positioning of the adjusting gasket. Specifically, the threaded connector 2 passes through the through hole 1300 and the positioning groove 1100 in sequence and is threadedly connected with the threaded hole 1000 to complete the alignment installation, and a rotation limit is formed between the threaded connector 2 and the positioning groove 1100, thereby limiting the rotation range of the adjusting gasket.

[0043] In this embodiment, if Figure 3-4 As shown, the upper cover 10 has openings at both ends, and a first ring 101 is provided at one end; the base 13 has openings at both ends, and a second ring 131 is provided at one end; the first ring 101 extends into the opening of the base 13, and is separated from the second ring 131 to form a gas channel 3; the outer wall of the base 13 is provided with a flame stabilizing hole 132, and the base 13 is provided with a connecting hole 133, and the center line of the connecting hole 133 is perpendicular to the end face of one end of the base 13; the fire hole 14 is connected to the gas channel 3, and the flame stabilizing hole 132 is provided on the outer wall of the base 13, and the connecting hole 133 is provided on the outer wall of the base 13. 32 is connected with the gas channel 3 through the connecting hole 133. In this way, on the one hand, during assembly, the end of the upper cover 10 with the first ring 101 is inserted into the opening of the base 13 to prevent radial movement between the upper cover 10 and the base 13, thereby improving the assembly convenience and stability of the upper cover 10 and the base 13; on the other hand, the center line of the connecting hole 133 is perpendicular to the end face of one end of the base 13, which is convenient for mold forming or machining, and the flame stabilizing hole 132 is connected with the gas channel 3 through the connecting hole 133, so that the flame combustion is more stable.

[0044] Of course, the shape of the flame stabilizing hole 132 can be a round hole, a square hole, an annular slot, etc., which is not limited here.

[0045] In another embodiment, the adjusting member 11 includes at least two adjusting gaskets; any number of the adjusting gaskets are stacked and respectively abut against the upper cover 10 and the base 13; or, the heights of the at least two adjusting gaskets are different, and any one of the adjusting gaskets is respectively abutted against the upper cover 10 and the base 13; in this way, the distance between the upper cover 10 and the base 13 can be adjusted, so as to adjust the width of the fire hole 14 to adapt to the use requirements of different gas source pressures or heat loads.

[0046] In another embodiment, the embodiment of the utility model further provides a cooker, comprising the above-mentioned burner.

[0047] The stove provided by the utility model includes the above-mentioned burner, and its technical effect is brought by the above-mentioned burner, which is the same as the technical effect of the above-mentioned burner, so it will not be described in detail.
