DETAILED DESCRIPTION
[0032] Example embodiments now will be described more fully hereinafter with reference to the accompanying drawings; however, the example embodiments can be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. Like reference numerals refer to like elements throughout the figures, and thus a detailed description of the same will not be repeated.
[0033] The terms "a", "an", "the" and "said" are used to refer to one or more than one (i.e., to "at least one") of the referenced elements / constituents / etc.; the terms "comprising", "having" and "including" are used to mean "including but not limited to" and permit the presence of additional elements / constituents / etc. not specifically listed.
[0034] Referring to Figures 1 to 5 The example embodiments provide a fire divider, which comprises a fire seat 1 and an outer ring fire cover 2, the fire seat 1 comprises an outer ring air distribution groove 11 and an inner ring air distribution groove 12, the outer ring air distribution groove 11 comprises a groove bottom 111, an inner groove wall 112 and an outer groove wall 113, the outer groove wall 113 is arranged outside the inner groove wall 112, the groove bottom 111 connects the inner groove wall 112 and the outer groove wall 113, the outer groove wall 113, the groove bottom 111 and the inner groove wall 112 form the outer ring air distribution groove 11, and the inner groove wall 112 and a groove wall of the inner ring air distribution groove 12 form an annular space 4. During combustion, air can be supplemented from the annular space 4 for more complete combustion.
[0035] The outer ring fire cover 2 is arranged above the outer ring air distribution groove 11 and is used for covering the outer ring air distribution groove 11, the outer ring fire cover 2 comprises a fire cover top surface 21 and a fire cover inner ring surface 22, the fire cover inner ring surface 22 is arranged on a side facing the inner ring air distribution groove 12, the outer ring fire cover 2 is provided with an outer ring fire groove 23, the outer ring fire groove 23 is located at a junction of the fire cover top surface 21 and the fire cover inner ring surface 22, and one side of the outer ring fire groove 23 extends to the fire cover top surface 21 and the other side extends to the fire cover inner ring surface 22.
[0036] In the example embodiments, referring to Figure 4The outer ring fire groove 23 is located at the junction of the fire cover top surface 21 and the fire cover inner ring surface 22, and one side of the outer ring fire groove 23 extends to the fire cover top surface 21, and the other side extends to the fire cover inner ring surface 22. The distribution area is large. Even if the diameter of the outer ring fire groove 23 of the burner is small, it can still maintain a sufficient area of the flame 5 and provide a larger heat load. At the same time, since the outer ring fire groove 23 spans the fire cover top surface 21 and the fire cover inner ring surface 22, the root of the flame 5 is also partially located at the fire cover top surface 21 and partially located at the fire cover inner ring surface 22. The secondary air supplemented through the fire cover top surface 21 is supplemented to the root of the flame 5 located at the fire cover top surface 21, and the secondary air supplemented by the annular space 4 is supplemented to the root of the flame 5 at the displacement fire cover inner ring surface 22, which can greatly promote the full combustion of the gas and reduce the carbon monoxide content.
[0037] In some embodiments, see Figure 2 and Figure 5 The inner annular surface 22 of the fire cover includes a first annular surface 221 at the bottom and a second annular surface 222 at the top. The diameter of the second annular surface 222 gradually increases from bottom to top. The second annular surface 222 is connected to the top surface 21 of the fire cover. The portion of the outer ring fire groove 23 extending to the inner annular surface 22 of the fire cover is located on the second annular surface 222. The second annular surface 222 at the top of the outer ring fire cover 2 is tilted outward, increasing the diameter of the top of the second annular surface 222, facilitating the arrangement of more outer ring fire grooves 23 and increasing the heat load.
[0038] In some embodiments, see Figure 1 and Figure 2 The top surface 21 of the fire cover is curved, gradually sloping downward from the inside out along the diameter direction. This curved surface facilitates the flow of secondary compensation air along the top surface 21, thereby replenishing the base of the flame 5. Furthermore, the top surface 21 of the fire cover can also cooperate with the energy-gathering ring 7 on the pot support 6, so that the cross-section of the replenishment air channel formed between the energy-gathering ring 7 and the top surface 21 of the fire cover is trumpet-shaped. Air flows from the outside to the inside, increasing the replenishment air speed and ensuring more complete combustion.
[0039] In some embodiments, the generatrix of the fire cover top surface 21 is a straight line and / or a curve. For example, when the generatrix is a straight line, the curved surface of the fire cover top surface 21 can be a conical surface. Alternatively, when the generatrix is a curved surface, the curved surface of the fire cover top surface 21 can be a spherical surface depending on the shape of the curve.
[0040] In some embodiments, see Figure 2 and Figure 3The outer ring fire cover 2 comprises a flame stabilizing ring 24 and an outer fire cover 25. The flame stabilizing ring 24 is connected with the inner groove wall 112, and a groove 241 is formed on the top of the flame stabilizing ring 24. The outer fire cover 25 comprises an outer ring wall 251 and a top cover 252. The top cover 252 is connected with the upper edge of the outer ring wall 251, and the outer ring wall 251 is connected with the outer groove wall 113. The top cover 252 is connected with the flame stabilizing ring 24, so that the groove 241 forms the outer ring fire groove 23. The outer ring fire cover 2 comprises the flame stabilizing ring 24 and the outer fire cover 25. The groove 241 is formed on the top of the flame stabilizing ring 24 to form the outer ring fire groove 23, which is easy to process and can make the cross section of the outer ring fire groove 23 close to the outer ring gas distribution groove 11 be not less than the cross section of the outer ring fire groove 23 far from the outer ring gas distribution groove 11. When the gas flows from the outer ring gas distribution groove 11 to the outside along the outer ring fire groove 23, the cross section of the gas is equal or from a large cross section to a small cross section. The kinetic energy of the gas remains unchanged or increases, which is beneficial to mix more oxygen and burn more fully.
[0041] In the embodiment of the utility model, the outer ring fire groove 23 can be cut. For example, when the outer ring fire cover 2 is an integral structure, the outer ring fire groove 23 can be cut at the junction of the fire cover top surface 21 and the fire cover inner ring surface 22 to span the fire cover top surface 21 and the fire cover inner ring surface 22. When the outer ring fire cover 2 comprises the flame stabilizing ring 24 and the outer fire cover 25, the groove 241 is cut on the top of the flame stabilizing ring 24. After the flame stabilizing ring 24 and the outer fire cover 25 are combined, the groove 241 forms the outer ring fire groove 23.
[0042] In some embodiments, the outer fire cover 25 and the flame stabilizing ring 24 can be abutted or overlapped. For example, the top cover 252 of the outer fire cover 25 is abutted with the flame stabilizing ring 24. Alternatively, the top cover 252 of the outer fire cover 25 is abutted with the outer side of the top of the flame stabilizing ring 24. The outer fire cover 25 and the flame stabilizing ring 24 are connected to form the outer ring fire cover 2, the outer ring fire groove 23 is formed at the groove 241, the gas in the outer ring gas distribution groove 11 flows out from the outer ring fire groove 23 and burns to generate the flame 5, and the secondary air is supplemented from both sides to the root of the flame 5 to promote more complete combustion.
[0043] In some embodiments, referring to Figure 5 The top of the flame stabilizing ring 24 comprises a first top surface 242 and a second top surface 243. The first top surface 242 is lower than the second top surface 243, and the first top surface 242 is located outside the second top surface 243. The top cover 252 is connected with the first top surface 242, and the top surface of the top cover 252 and the second top surface 243 form the fire cover top surface 21 of the outer ring fire cover 2. The first top surface 242 and the second top surface 243 form a stepped structure. The top cover 252 of the outer fire cover 25 is matched with the stepped structure to realize the overlapping with the flame stabilizing ring 24. The outer fire cover 25 and the flame stabilizing ring 24 are connected through the stepped structure, and the sealing between the two is good, so that the gas only flows out from the outer ring fire groove 23.
[0044] The outer fire cover 25 cooperates with the step structure on the top of the flame stabilizing ring 24 to make the top surface of the top cover 252 flush with the second top surface 243, forming a smooth fire cover top surface 21 of the outer ring fire cover 2.
[0045] In some embodiments, see Figure 5 The flame stabilizing ring 24 includes a vertical section 244 and a reducing section 245. The lower end of the vertical section 244 is connected to the inner groove wall 112. The vertical section 244 is cylindrical. The lower end of the reducing section 245 is connected to the vertical section 244. The reducing section 245 is conical, with its diameter gradually increasing from bottom to top. The reducing section 245 defines a groove 241. The second annular surface 222 of the inner annular surface 22 of the fire cover is located in the reducing section 245, while the first annular surface 221 is located in the vertical section 244. The reducing section 245 is tilted outward relative to the vertical section 244 and defines a groove 241 to facilitate the formation of the outer ring fire groove 23 when combined with the outer fire cover 25. The groove 241 in the reducing section 245 facilitates the upward tilt of the outer ring fire groove 23, allowing the flame 5 formed to be diagonally above the outer ring fire cover 2, where it is supplemented with air for a second time, resulting in more complete combustion.
[0046] The bottom of the flame stabilizing ring 24 can form a step structure that matches the inner groove wall 112 to connect the flame stabilizing ring 24 to the inner groove wall 112. Of course, the top of the inner groove wall 112 can also form a step structure that matches the bottom of the flame stabilizing ring 24 to connect the flame stabilizing ring 24 to the inner groove wall 112.
[0047] The bottom of the outer fire cover 25 can form a step structure that matches the outer groove wall 113 to connect the outer fire cover 25 to the outer groove wall 113. Of course, the top of the outer groove wall 113 can also form a step structure that matches the bottom of the outer fire cover 25 to connect the outer fire cover 25 to the outer groove wall 113.
[0048] In some embodiments, the angle between the center plane of the groove 241 and the center line of the flame stabilization ring 24 is acute. When cutting the groove 241 at the top of the flame stabilization ring 24, the plane on which the cutter is located is tilted relative to the center line of the flame stabilization ring 24, so that a certain angle is formed between the center plane of the groove 241 and the center line of the flame stabilization ring 24. This increases the cross-sectional area of the groove 241, that is, increases the cross-sectional area of the outer ring fire groove 23, thereby increasing the maximum heat load.
[0049] In some embodiments, the centerline of the outer ring fire groove 23 is tilted in the horizontal direction to form an inwardly rotating flame 5. Depending on the tilt direction of the centerline of the outer ring fire groove 23 in the horizontal direction, the rotation direction of the inwardly rotating flame 5 can be counterclockwise or clockwise.
[0050] In some embodiments, the centerline of the outer ring fire groove 23 is tilted upward in the vertical direction. The upward tilt of the centerline of the outer ring fire groove 23 can cause the flame 5 to tilt upward, preventing the flame 5 generated by the outer ring fire groove 23 from being too close to the inner ring gas distribution groove 12 when the heat load is large, thereby preventing incomplete combustion.
[0051] When the center line of the outer ring fire groove 23 is inclined in both the horizontal and vertical directions, the outer ring fire groove 23 generates an upwardly inclined inward rotating flame 5 .
[0052] See also Figure 6 , an embodiment of the present utility model provides a burner, including the ignition distributor of the embodiment of the present utility model.
[0053] See also Figure 7 , an embodiment of the present utility model provides a gas stove, including the burner of the embodiment of the present utility model.
[0054] In some embodiments, see Figure 4 and Figure 7 The gas stove of this embodiment of the utility model further includes a pot support 6, on which is provided an energy-gathering ring 7. The space formed between the energy-gathering ring 7 and the top surface of the outer ring fire cover 2 has a bell-shaped cross-section along the diameter of the burner, with the cross-section being larger inside and smaller outside. Secondary air flows from outside to inside between the energy-gathering ring 7 and the top surface of the outer ring fire cover 2, resulting in faster combustion and more complete combustion.
[0055] In some embodiments, the energy focusing ring 7 is gradually inclined downward from the outside to the inside along the diameter direction. The gradually downward sloping energy focusing ring 7 can be combined with the gradually upward sloping fire cover top surface 21 from the inside to the outside, and the space formed is accelerated by secondary supplementary air to promote complete combustion.
