[0006] An inner ring base, the inner ring base having a gas mixing cavity, the side wall of the gas mixing cavity being provided with fire holes arranged along the circumference of the side wall;
[0007] A cap, the cap is disposed on the top of the inner ring base, and the cap is configured to be able to move relative to the inner ring base along the axial direction of the inner ring base;
[0008] A plurality of circumferentially arranged columns are provided at the bottom of the cap, the columns are located on the inner side of the mixing chamber, the columns extend downward from the bottom wall of the cap, and the gap between two adjacent columns transitions from large to small along the direction close to the top of the cap.
[0009] In the present solution, the above-mentioned structural form is adopted. When the user controls the cap to move up and down relative to the inner ring base, the air outlet area of the air outlet channel between the two adjacent columns will be adjusted accordingly, so as to realize continuous adjustment of the air outlet area of the burner to adjust the load of the gas stove, thereby flexibly controlling the size of the flame and the heat output, meeting the need for targeted adjustment of the load in different cooking scenarios, which is beneficial to energy saving during the cooking process, and can also ensure the efficient use of gas.
[0010] Preferably, in the radial direction of the gas mixing chamber, along the direction away from the center of the gas mixing chamber, the gap between two adjacent columns gradually increases.
[0011] In this solution, by adopting the above-mentioned structural form, the gas flow velocity can be slowed down after the gas is sprayed out from the inner side of the column, thereby improving the flame stabilization performance, thereby solving the problem of gas flame separation of the burner due to excessive gas flow rate.
[0012] Preferably, the inner wall surface of the column and / or the outer wall surface of the column is an arc surface.
[0013] In this solution, the above-mentioned structural form is adopted to reduce air flow resistance.

[0016] Preferably, the fire hole is a tooth-shaped fire hole, which is a groove extending from the top of the inner ring base toward the bottom of the inner ring base, and a fire hole ridge is formed between adjacent grooves.
[0017] In the present solution, the above-mentioned structural form is adopted. By adjusting the relative rotation between the cap and the inner ring base, the area of the groove blocked by the cap is adjusted accordingly, that is, the opening area of the fire hole is adjusted, and the air outlet area of the air outlet channel between two adjacent columns will be adjusted accordingly, providing more flexible firepower adjustment and ensuring combustion stability.
[0018] Preferably, the tooth-shaped fire holes include a plurality of first fire holes and at least one second fire hole;

[0057] Panel 3 DETAILED DESCRIPTION
[0058] The present invention will be described more clearly and completely below by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the following embodiments.
[0059] Please combine Figures 1 to 6For understanding, the embodiment of the utility model provides a burner fire cover 1, which includes an inner ring base 11 and a cap 13, the inner ring base 11 has an air mixing chamber 111, and the side wall 1111 of the air mixing chamber 111 is provided with fire holes 12 arranged circumferentially along the side wall 1111; the cap 13 is covered on the top of the inner ring base 11, and the cap 13 is configured to be able to move along the axial direction of the inner ring base 11 relative to the inner ring base 11, and a plurality of circumferentially arranged columns 14 are provided at the bottom of the cap 13, and the columns 14 are located on the inner side of the air mixing chamber 111, and the columns 14 extend downward from the bottom wall of the cap 13, and along the direction close to the top of the cap 13, the gap between two adjacent columns 14 transitions from large to small.
[0060] In this embodiment, the gas introduced into the gas mixing chamber 111 can pass through the gas outlet passage between two adjacent columns 14, and then flow out from the fire hole 12 opened on the inner ring base 11 for combustion. The control cap 13 moves upward relative to the inner ring base 11, that is, as the height of the cap 13 relative to the inner ring base 11 gradually increases, on the same horizontal plane of the fire hole 12, the gap between the two adjacent columns 14 corresponding to the fire hole 12 becomes larger, that is, the cross-sectional area of the gas outlet passage between the two adjacent columns 14 corresponding to the fire hole 12 becomes larger; as the height of the cap 13 relative to the inner ring base 11 gradually decreases, on the same horizontal plane of the fire hole 12, the gap between the two adjacent columns 14 corresponding to the fire hole 12 becomes smaller, that is, the cross-sectional area of the gas outlet passage becomes smaller. In other words, when the user controls the cap 13 to move up and down relative to the inner ring base 11, the air outlet area of the air outlet channel between two adjacent columns 14 will be adjusted accordingly, so as to continuously adjust the air outlet area of the burner to adjust the load of the gas stove, thereby flexibly controlling the size of the flame and the heat output, meeting the need for targeted adjustment of the load in different cooking scenarios, which is beneficial to energy saving during the cooking process and can also ensure efficient use of gas.
[0061] Specifically, Figure 2 As shown, the inner ring base 11 has a mixing chamber 111 opening downward, which is specifically embodied as follows: a plurality of vents 112 are opened on the bottom wall of the mixing chamber 111, and the gas enters the mixing chamber 111 through the vents 112. Specifically, as Figure 4 and Figure 6 As shown, 12 circumferentially evenly arranged columns 14 are provided at the bottom of the cap 13. Of course, the number of the columns 14 can be selected according to actual needs and is not limited here.
[0062] Preferably, along the axial direction of the inner ring base 11, the length of the column 14 is greater than the maximum depth of the fire hole 12, so as to avoid the cross-sectional area of the air outlet channel between two adjacent columns 14 corresponding to the fire hole 12 remaining unchanged on the same horizontal plane of the fire hole 12 during the process of adjusting the position of the cap 13.
[0063] In this embodiment, if Figure 6 As shown, in the radial direction of the gas mixing chamber 111, the gap between two adjacent columns 14 gradually increases along the direction away from the center of the gas mixing chamber 111, that is, the gas outlet channel between the two adjacent columns 14 forms an expansion section. According to the Bernoulli principle, the gas flow velocity can be slowed down after the gas is ejected from the inner side of the column 14, thereby improving the flame stabilization performance, thereby solving the problem of gas flame separation of the burner due to excessive gas flow velocity.
[0064] In this embodiment, if Figure 4 and Figure 6 As shown, the inner wall surface of the column 14 is an arc surface, thereby reducing airflow resistance. In other embodiments, as an alternative means, the outer wall surface of the column 14 is an arc surface. Alternatively, both the inner wall surface and the outer wall surface of the column 14 can be set as an arc surface.
[0065] In this embodiment, if Figure 2 As shown, the cap 13 is engaged with the side wall 1111 of the inner ring base 11 by threaded rotation. Through the threaded engagement between the cap 13 and the inner ring base 11, the cap 13 can be moved relative to the axial direction of the inner ring base 11, which is convenient for user operation.
[0066] More specifically, if Figure 4 and Figure 5 As shown, a brim 131 extending outward from the outer side wall of the cap 13 is provided on the top of the cap 13 , which can effectively prevent overflow from entering the gas mixing chamber 111 through the cap 13 .
[0067] In this embodiment, if Figure 2 and Figure 3As shown, the fire hole 12 is a tooth-shaped fire hole 12, which is a groove extending from the top of the inner ring base 11 to the bottom of the inner ring base 11, and a fire hole ridge 15 is formed between adjacent grooves. The tooth-shaped fire hole design can achieve better gas distribution and flame shape control. Rotate the cap 13 in a first direction (for example, counterclockwise), control the cap 13 to gradually decrease in height relative to the inner ring base 11, and the fire hole 12 is gradually blocked by the cap 13, and the opening area of the fire hole 12 is reduced accordingly. At the same time, the cross-sectional area of the gas outlet channel between the two adjacent columns 14 corresponding to the fire hole 12 is reduced; rotate the cap 13 in a second direction opposite to the first direction (for example, clockwise), control the cap 13 to gradually increase in height relative to the inner ring base 11, and the part of the fire hole 12 blocked by the cap 13 is gradually restored, and the opening area of the fire hole 12 is increased accordingly. At the same time, the cross-sectional area of the gas outlet channel between the two adjacent columns 14 corresponding to the fire hole 12 is increased. By adjusting the relative rotation between the cap 13 and the inner ring base 11, the area of the groove blocked by the cap 13 is adjusted accordingly, that is, the opening area of the fire hole 12 is adjusted, and the air outlet area of the air outlet channel between two adjacent columns 14 will be adjusted accordingly, providing more flexible firepower adjustment and ensuring combustion stability.
[0068] Specifically, the threads on the inner ring base 11 are arranged on the outer side wall of the fire hole ridge 15, and the threads on the cap 13 are arranged on the inner wall of the cap 13. In other embodiments, the threads on the inner ring base 11 can also be arranged on the inner wall of the fire hole ridge 15, and the threads on the cap 13 are arranged on the outer wall of the cap 13.
[0069] In other embodiments, the fire hole 12 may be in other shapes, such as rectangular, circular, or fan-shaped.
[0070] In some embodiments, Figure 3 As shown, the tooth-shaped fire hole includes a plurality of first fire holes 121 and at least one second fire hole 122; the extension depth of the groove of the first fire hole 121 is greater than the extension depth of the groove of the second fire hole 122, and the second fire hole 122 is arranged between the two first fire holes 121. The first fire hole 121 serves as the main fire hole, and the second fire hole 122 serves as the flame-stabilizing fire hole. The main fire hole is deeper than the flame-stabilizing fire hole, and more gas passes through, thereby producing a larger or stronger flame. The flame-stabilizing fire hole is used to provide a stable flame. The groove width of the first fire hole 121 is greater than the groove width of the second fire hole 122. In other words, the main fire hole is wider than the flame-stabilizing fire hole. Specifically, a main fire hole and a flame-stabilizing fire hole are recorded as a group, and the number of gaps between the two columns 14 corresponds to the number of fire holes 12 one by one. In this embodiment, a total of 12 groups of fire holes 12 are arranged on the inner ring base 11. It should be noted that the number of fire holes 12 can be selected according to actual needs and is not limited here.
[0071] In some embodiments, a first flame stabilizing hole 16 is provided on the fire hole ridge 15. The cap 13 is rotated in a first direction so that the height of the cap 13 relative to the inner ring base 11 is gradually reduced, the fire hole 12 and the first flame stabilizing hole 16 are gradually blocked by the cap 13, and the opening areas of the fire hole 12 and the first flame stabilizing hole 16 are reduced accordingly; the cap 13 is rotated in a second direction so that the height of the cap 13 relative to the inner ring base 11 is gradually increased, the parts of the fire hole 12 and the first flame stabilizing hole 16 blocked by the cap 13 are gradually restored, and the opening areas of the fire hole 12 and the first flame stabilizing hole 16 are increased accordingly. By adjusting the relative rotation between the cap 13 and the inner ring base 11, while adjusting the opening area of the fire hole 12, the ventilation area of the first flame stabilizing hole 16 also changes with the adjustment of the heat load, thereby achieving the effect of enhancing flame stabilization. The side wall 1111 of the gas mixing chamber 111 is also provided with second flame stabilizing holes 17 arranged circumferentially along the side wall 1111, and the second flame stabilizing holes 17 are located below the first fire hole 121. The second flame stabilizing holes 17 can further improve the stability of the gas outflow in the burner fire cover 1. The side wall 1111 of the gas mixing chamber 111 is also provided with third flame stabilizing holes 18 arranged circumferentially along the side wall 1111, and the third flame stabilizing holes 18 are located below the second fire hole 122. The third flame stabilizing holes 18 can further improve the stability of the gas outflow in the burner fire cover 1.
[0072] Specifically, along the axial direction of the inner ring base 11, three circles of circumferentially arranged first flame stabilizing holes 16 are opened on the fire hole ridge 15. Of course, the number and arrangement of the first flame stabilizing holes 16 can be selected according to actual needs and are not limited here.
[0073] Specifically, the threaded portion on the side wall 1111 of the inner ring base 11 extends from the top of the fire hole ridge 15 to the bottom of the fire hole ridge 15, and the extension length of the threaded portion does not exceed the depth of the groove of the second fire hole 122. With this design, even if the cap 13 can completely block the second fire hole 122, the first fire hole 121 can still maintain a certain ventilation area. Along the circumference of the side wall 1111, a circle of second flame stabilization holes 17 and a circle of third flame stabilization holes 18 are provided on the side wall 1111, and the second flame stabilization holes 17 are located between the first flame stabilization holes 16 and the third flame stabilization holes 18.
[0074] In this embodiment, the columns 14 are spaced apart from the inner wall of the mixing chamber 111. During the rotation of the cap 13, when the gap between two adjacent columns 14 is misaligned with the fire hole 12 on the inner ring base 11, some of the gas can still directly pass through the space between the outer wall of the column 14 and the inner wall of the mixing chamber 111 into the fire hole 12, thereby avoiding blockage of the gas.
[0075] like Figure 7 As shown, the embodiment of the utility model further provides a burner 2, and the burner 2 includes the burner fire cover 1 as described above.
[0076] like Figure 8 As shown, an embodiment of the utility model further provides a gas stove, which includes a panel 3 and the burner 2 as described above, and the burner 2 is installed on the panel 3.
[0077] Although the specific implementations of the utility model are described above, those skilled in the art should understand that this is only an example, and the protection scope of the utility model is defined by the attached claims. Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
