Detailed implementation manners

[0033] Now, the exemplary embodiments will be described more fully with reference to the accompanying drawings. However, the exemplary embodiments can be implemented in various forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this utility model will be thorough and complete, and the concept of the exemplary embodiments will be fully conveyed to those skilled in the art. The same reference numerals in the figures denote the same or similar structures, and thus their detailed descriptions will be omitted.

[0034] The terms "a", "an", "the", "" are used to indicate the existence of one or more elements / components / etc.; the terms "comprising" and "having" are used to mean an open inclusion and refer to the existence of additional elements / components / etc. in addition to the listed elements / components / etc.

[0035] See Figures 1 to 6, an embodiment of the present utility model provides a flow dividing baffle 100, which is used to be arranged in the outer ring gas distribution groove 210 of the gas divider 200. The flow dividing baffle 100 of the embodiment of the present utility model includes a plate body 110 and a through hole 120 arranged on the plate body 110, and the plate body 110 is used to axially divide the outer ring gas distribution groove 210 into two parts. The plate body 110 has opposite first and second surfaces, the first surface faces the side of the air inlet 260 of the gas divider 200, and the second surface faces the side of the air outlet 270 of the gas divider 200. The through hole 120 communicates the first surface and the second surface, so that the combustion gas enters from the first surface side to the second surface side, and the flow direction of the combustion gas entering the second surface from the through hole 120 is not parallel to the center line of the outer ring gas distribution groove 210.

[0036] In the embodiment of the present utility model, referring to Figure 5 , the flow dividing baffle 100 axially divides the outer ring gas distribution groove 210 into two parts. Among them, the first surface side is the first cavity 211, and the second surface side is the second cavity 212. The first cavity 211 communicates with the air inlet 260, and the second cavity 212 communicates with the air outlet 270. The combustion gas enters the first cavity 211 from the air inlet 260. A part of the combustion gas flows away from the air inlet 260 along the first cavity 211, and another part of the combustion gas enters the second cavity 212 through the through hole 120. Due to the blockage of the flow dividing baffle 100, the combustion gas flows away from the air inlet 260 in the first cavity 211, and the combustion gas can uniformly enter the second cavity 212, so that the combustion gas can be uniformly discharged and burned from the air outlet 270, improving the phenomenon of uneven flame caused by uneven distribution of the combustion gas. In addition, the amount of combustion gas directly rushing from the air inlet 260 upward to the air outlet 270 is reduced, and the speed is slowed down, improving the situation of flame lift caused by too fast air flow at the air outlet 270 above the air inlet 260. The flow direction of the combustion gas entering the second surface from the through hole 120 is not parallel to the center line of the outer ring gas distribution groove 210, changing the flow direction of the combustion gas, preventing the combustion gas from vertically entering the second cavity 212 along the axis, slowing down the flow rate of the combustion gas, improving the situation of flame lift, and enabling the combustion gas to be more evenly distributed in the second cavity 212, improving the phenomenon of uneven flame.

[0037] In the embodiment of the present utility model, referring to Figure 5 and Figure 6, the flame distributor 200 may include a flame distribution base 220, which has an annular groove. An outer ring flame cover 230 is provided on the annular groove. The outer ring flame cover 230 closes the annular groove to form an outer ring gas distribution groove 210. An air outlet 270 is provided on the outer ring flame cover 230, and the air outlet 270 on the outer ring flame cover 230 can also be a flame hole. An air inlet 260 is provided at the bottom of the outer ring gas distribution groove 210. Providing one air inlet 260 in the outer ring gas distribution groove 210 can simplify the structure of the flame distributor 200 and reduce materials. The flow splitting baffle 100 in the embodiment of the present invention improves the uneven combustion gas distribution caused by providing one air inlet 260 in the outer ring gas distribution groove 210, resulting in the phenomenon of uneven fire, and also improves the phenomenon of flame detachment caused by the relatively fast flow rate near the air inlet 260.

[0038] See Figure 5 and Figure 6 , the flame distributor 200 in the embodiment of the present invention may also have an inner ring gas distribution groove 240, and an inner ring flame cover 250 is provided on the inner ring gas distribution groove 240. The outer ring gas distribution groove 210 is arranged to surround the inner ring gas distribution groove 240.

[0039] In some embodiments, see Figure 1 and Figure 2 , it may be that the axis of the through hole 120 is not parallel to the center line of the outer ring gas distribution groove 210, so that the flow direction of the combustion gas entering the second surface from the through hole 120 is not parallel to the center line of the outer ring gas distribution groove 210. The axis of the through hole 120 and the center line of the outer ring gas distribution groove 210 may be skew lines, and the included angle between the axis of the through hole 120 and the center line of the outer ring gas distribution groove 210 may also be an acute angle.

[0040] When the axis of the through hole 120 and the center line of the outer ring gas distribution groove 210 are skew lines, the flow direction of the combustion gas entering the second cavity 212 from the through hole 120 has a tangential component. According to the inclination direction of the axis of the through hole 120, this tangential component can make the combustion gas flow clockwise or counterclockwise in the second cavity 212.

[0041] When the included angle between the axis of the through hole 120 and the center line of the outer ring gas distribution groove 210 forms an acute angle, the component of the flow direction of the combustion gas entering the second cavity 212 in the direction perpendicular to the center line of the outer ring gas distribution groove 210 can be in the direction away from the center of the outer ring gas distribution groove 210. For example, the axis of the through hole 120 can be inclined outward.

[0042] In some embodiments, see Figure 3 and Figure 4, or a flow guide plate 130 for guiding the flow direction of the combustion gas may be provided on the second surface, so that the flow direction of the combustion gas entering the second surface from the through hole 120 is not parallel to the center line of the outer ring gas distribution groove 210. The flow guide plate 130 may be provided at the edge of the through hole 120. By providing the flow guide plate 130 on the second surface to guide the flow direction of the combustion gas entering the second cavity 212 from the through hole 120, the flow direction of the combustion gas is changed, and the combustion gas is prevented from entering the second cavity 212 vertically along the axis.

[0043] In some embodiments, the flow guide plate 130 is formed by stamping. By stamping the plate body 110, while forming the through hole 120 in the plate body 110, a flow guide plate 130 protruding from the second surface is formed on the second surface, and the process is simple and easy to manufacture.

[0044] By providing the flow guide plate 130 on the second surface to guide the flow direction of the combustion gas, the flow direction of the combustion gas entering the second cavity 212 can be adjusted more flexibly. By providing the flow guide plate 130, the flow direction of the combustion gas entering the second cavity 212 can be made substantially perpendicular to the center line of the outer ring gas distribution groove 210.

[0045] In some embodiments, the included angle between the center line of the flow guide plate 130 and the second surface is not greater than 75°. The size of the included angle between the center line of the flow guide plate 130 and the second surface affects the flow direction of the combustion gas entering the second cavity 212. The larger the included angle between the center line of the flow guide plate 130 and the second surface, the closer the center line of the flow guide plate 130 is to being parallel to the center line of the outer ring gas distribution groove 210.

[0046] In some embodiments, the shape of the through hole 120 may be a regular or irregular geometric shape such as a circle or a rectangle.

[0047] In some embodiments, see Figure 3 and Figure 4 , the contour line of the through hole 120 on the second surface includes a first straight edge, the flow guide plate 130 surrounds the connection of the through hole 120 and the second surface, and an opening is formed at the first straight edge. The flow guide plate 130 forms an opening on one side of the first straight edge, which can make the flow guide plate 130 flush with the first straight edge, and can better control the flow direction of the combustion gas entering the second cavity 212 according to the shape of the flow guide plate 130. The other sides of the through hole 120 may be straight edges or curved edges. For example, the through hole 120 may be approximately triangular or rectangular, so that one of the sides of the triangle or rectangle forms the first straight edge. The through hole 120 may also be approximately semicircular, and the chord of the semicircle forms the first side.

[0048] In some embodiments, the first straight edge is collinear with the radius of the outer ring gas distribution groove 210. The first straight edge being collinear with the radius of the outer ring gas distribution groove 210 is beneficial to the formation of a tangential component of the flow direction of the combustion gas, and the tangential component is beneficial to the flow of the combustion gas along the second cavity 212.

[0049] In some embodiments, the first straight edge and the radius of the outer ring gas distribution groove 210 may also form a certain included angle, so that the opening direction of the deflector 130 is inclined outward.

[0050] In some embodiments, referring to Figure 3 , the contour line of the through hole 120 on the second surface includes an arc and a chord connecting both ends of the arc, the chord forms the first straight edge, and the deflector 130 is connected to the second surface along the arc. Through stamping, a semi-circular through hole 120 can be formed on the plate body 110. The part of the plate body 110 corresponding to the through hole 120 is disconnected along the chord of the semi-circle, and the remaining part is connected to the plate body 110 and extended to the second surface side by stamping to form the deflector 130. The shape of the deflector 130 can be a curved surface. In specific embodiments, the deflector 130 can be a spherical surface, an ellipsoidal surface or a composite curved surface.

[0051] In some embodiments, referring to Figure 4 , the contour of the through hole 120 on the second surface is a rectangle, and one of the long sides of the rectangle forms the first straight edge, and the deflector 130 is connected to the second surface along the other three sides of the rectangle. Through stamping, a rectangular through hole 120 can be formed on the plate body 110. The part of the plate body 110 corresponding to the through hole 120 is disconnected along one of the long sides of the rectangle, and the remaining part is connected to the plate body 110 and extended to the second surface side by stamping to form the deflector 130.

[0052] In some embodiments, referring to Figure 4 , the contour of the through hole 120 on the second surface is a rectangle, and one of the long sides of the rectangle forms the first straight edge. The deflector 130 includes a first inclined plate 131, a second inclined plate 132, a third inclined plate 133 and a top plate 134. The first inclined plate 131, the second inclined plate 132 and the third inclined plate 133 are connected in sequence and are respectively connected to the other three sides of the top plate 134 except the first straight edge. The first inclined plate 131, the second inclined plate 132 and the third inclined plate 133 are respectively connected to the top plate 134, and the area of the top plate 134 is smaller than the area of the rectangle. The combustion gas flowing into the through hole 120 flows upward under the guidance of the first inclined plate 131, the second inclined plate 132 and the third inclined plate 133, and flows out from the opening on one side of the first straight edge under the guidance of the top plate 134. According to the relationship between the plane where the top plate 134 is located and the center line of the outer ring gas distribution groove 210, the flow direction of the combustion gas can be adjusted. For example, the plane where the top plate 134 is located and the center line of the outer ring gas distribution groove 210 can be perpendicular, so that the flow direction of the combustion gas entering the second cavity 212 is substantially perpendicular to the center line of the outer ring gas distribution groove 210.

[0053] In some embodiments, the flow dividing baffle 100 may be annular, that is, the plate body 110 is an annular shape. The annular flow dividing baffle 100 divides the entire outer ring gas dividing groove 210 into a first cavity 211 and a second cavity 212. Refer to Figures 1 to 4 , the flow dividing baffle 100 may also be a non-complete ring shape. The non-complete ring-shaped flow dividing baffle 100 divides the side of the outer ring gas dividing groove 210 near the air inlet 260 into a first cavity 211 and a second cavity 212. The flow rate of the combustion gas on the side of the outer ring gas dividing groove 210 away from the air inlet 260 gradually decreases, and after being redistributed by the flow dividing baffle 100, the combustion gas is more evenly distributed. The flow dividing baffle 100 may adopt a non-complete ring shape. In a specific implementation, the flow dividing baffle 100 may be a semi-circular shape, three-quarter circular shape, two-thirds circular shape, two-fifths circular shape, etc.

[0054] In some embodiments, refer to Figure 3 and Figure 4 , for ease of understanding, the dashed line in the figure represents the virtual dividing line between the first part 111 and the second part 112. The plate body 110 includes a first part 111 and a second part 112. The first part 111 and the second part 112 have a first connecting part. The first part 111 extends in the clockwise direction from the first connecting part, and the second part 112 extends in the counterclockwise direction from the first connecting part. The first connecting part is opposite to the air inlet 260. The through hole 120 includes a first through hole 121 and a second through hole 122. The first through hole 121 is provided on the first part 111, and the tangential component of the flow direction of the combustion gas flowing out of the first through hole 121 drives the combustion gas to flow counterclockwise along the outer ring gas dividing groove 210. The second through hole 122 is provided on the second part 112, and the tangential component of the flow direction of the combustion gas flowing out of the second through hole 122 drives the combustion gas to flow clockwise along the outer ring gas dividing groove 210. The plate body 110 can be divided into two parts in the circumferential direction, and the through holes 120 on the two parts make the flow direction of the combustion gas different. Among them, the first through hole 121 on the first part 111 makes the combustion gas flow in the clockwise direction, and the second through hole 122 on the second part 112 makes the combustion gas flow in the counterclockwise direction. Thus, when the combustion gas enters the first cavity 211 from the air inlet 260 and enters the second cavity 212 through the through hole, it can flow away from the side of the air inlet 260 relatively, so that the combustion gas can be quickly distributed to the entire second cavity 212, the flow rate of the combustion gas is more uniform, and the phenomena of uneven flame and flameout are improved.

[0055] When the plate body 110 is annular, the first part 111 and the second part 112 may also have a second connecting part. The second part 112 is opposite to the first part 111, dividing the plate body 110 into two symmetrical parts. The plate body 110 may be integrally formed, so the first connecting part and the second connecting part do not indicate that this part has actual connection process treatment.

[0056] The through hole 120 enables the combustion gas to form a clockwise tangential component or a counterclockwise tangential component, which can be achieved by setting the inclination direction of the axis of the through hole 120 or by setting the opening direction of the flow guide plate 130. For example, the axis of the first through hole 121 is inclined in the clockwise direction to make the combustion gas form a clockwise tangential component. Or, the opening direction of the flow guide plate 130 at the first through hole 121 is set toward the clockwise direction to make the combustion gas form a clockwise tangential component. Similarly, the axis of the second through hole 122 can be inclined in the counterclockwise direction to make the combustion gas form a counterclockwise tangential component. Or, the opening direction of the flow guide plate 130 at the second through hole 122 is set toward the counterclockwise direction to make the combustion gas form a counterclockwise tangential component.

[0057] In some embodiments, referring to Figure 1 and Figure 2 , the plate body 110 includes a first plate body 113, a second plate body 114 and a connecting plate 115. The first plate body 113 has a first inner arc edge and a first outer arc edge, and the first inner arc edge is adapted to the first inner wall surface of the outer ring gas distribution groove 210; the second plate body 114 has a second inner arc edge and a second outer arc edge, the radius of the first outer arc edge is smaller than the radius of the second inner arc edge, the second outer arc edge is adapted to the second inner wall surface of the outer ring gas distribution groove 210, the second inner wall surface is opposite to the first inner wall surface, and the first inner wall surface is located inside the second inner wall surface. The second plate body 114 is lower than the first plate body 113; the connecting plate 115 connects the first outer arc edge and the second inner arc edge respectively; the through hole 120 is provided on the connecting plate 115. The first plate body 113 and the second plate body 114 can be perpendicular to the axis of the flow dividing baffle 100 respectively. The connecting plate 115 is basically a conical table surface. The through hole 120 is provided on the connecting plate 115, and the axis of the through hole 120 forms an acute angle with the axis of the outer ring gas distribution groove 210 directly.

[0058] In some embodiments, referring to Figures 1 to 4 and Figure 6 , the flow dividing baffle 100 further includes a first connection structure 140. The first connection structure 140 is provided on the plate body 110 and is adapted to the second connection structure 280 on the gas divider 200. Through the cooperation of the first connection structure 140 and the second connection structure 280, the flow dividing baffle 100 is connected in the outer ring gas distribution groove 210.

[0059] The first connection structure 140 and the second connection structure 280 can be inserted. In an exemplary embodiment, referring to Figure 6, the second connection structure 280 includes a socket provided on the inner wall surface of the outer ring gas distribution groove 210. The socket has a slot, and the first connection structure 140 includes a plug adapted to the slot. The plug is inserted into the slot to fix the flow dividing baffle 100 in the outer ring gas distribution groove 210. The first connection structure 140 and the second connection structure 280 adopt a quick-insert structure for plug-in self-locking, eliminating the need for screw fixation. On the one hand, it reduces the labor for screw tapping and fixation, and on the other hand, it also avoids forming obstructions in the outer ring gas distribution groove 210 by setting screw posts, which affects the flow of air and is not conducive to uniform flame.

[0060] In some embodiments, referring to Figure 2 , the free end of the plug has an axial notch 141. The notch 141 divides the free end of the plug into two parts, and on the side of the two parts away from the notch 141, there are protrusions 142 respectively. The protrusions 142 and the plug form a hook structure. When the plug is inserted into the slot, the two parts of the free end deform towards the notch 141. When plugged into the target position, the two parts of the free end recover deformation, and the protrusions 142 cooperate with the slot to achieve clamping. During disassembly, the two parts of the free end deform towards the notch 141, and the protrusions 142 are disengaged from the slot, thereby detaching the flow dividing baffle 100.

[0061] An embodiment of the present invention provides a burner, which includes a gas distributor 200. The gas distributor 200 has an outer ring gas distribution groove 210, as well as an air inlet 260 and an air outlet 270 communicating with the outer ring gas distribution groove 210. It further includes the flow dividing baffle 100 of the embodiment of the present invention. The flow dividing baffle 100 is disposed in the outer ring gas distribution groove 210 of the gas distributor 200.

[0062] An embodiment of the present invention provides a gas stove, which includes the burner of the embodiment of the present invention.

[0063] In the embodiments of the present invention, the term "a plurality of" refers to two or more, unless otherwise clearly defined. Terms such as "installation", "connection", and "fixation" should be understood in a broad sense.
