Description

Technical Field

[0001] This utility model relates to the field of burner technology, and in particular to a burner head structure and a stove body. Background Technology

[0002] The applicant had previously made improvements to the burner structure, which was relatively complex, including components such as the vaporizer and air filter, resulting in higher costs. In areas where heat output is relatively low, such as clay pot stoves, cost is even more critical, necessitating improvements to the burner structure to reduce the number of components and lower costs. Utility Model Content

[0003] Therefore, it is necessary to provide a burner head structure and stove body to solve the problem of the complexity of the existing burner head structure.

[0004] To achieve the above objectives, this utility model provides a burner head structure, including a burner head inner liner and a burner head outer shell. The burner head inner liner is fitted onto the burner head outer shell. Both the burner head inner liner and the burner head outer shell have fuel passage holes at their bottoms. The burner head inner liner, from top to bottom, includes an air-gathering ring, a ventilation ring, a first ventilation ring wall, and a mixing ring. The bottom of the air-gathering ring is connected to the outer edge of the ventilation ring, the top of the first ventilation ring wall is connected to the inner edge of the ventilation ring, and the bottom of the first ventilation ring wall is connected to the inner edge of the ventilation ring. The top of the mixing ring, the outer side of the venting ring plate is located on the outer shell of the burner head, the venting ring plate is provided with multiple vertical first vent holes, the side of the first venting ring wall is provided with multiple horizontal second vent holes, the side of the mixing ring is provided with multiple third vent holes, and the bottom of the mixing ring is provided with a fuel passage hole. The burner head structure also includes a vaporization core, the vaporization core is located in the middle of the inner liner of the burner head, the vaporization core includes an annular plate, a second venting ring wall and a lower sealing plate, the annular plate is annular with an opening in the middle. The structure includes a second venting ring wall connected to the inner edge of the annular plate, a lower sealing plate connected to the bottom of the second venting ring wall, and multiple fourth venting holes arranged laterally on the side of the second venting ring wall. The annular plate is placed on the lower inner side of the first venting ring wall. The second venting ring wall extends into the interior of the mixing ring, and a guide cavity is formed between the outer wall of the second venting ring wall and the upper part of the mixing ring. The lower sealing plate and the interior of the mixing ring form a mixing cavity. The height of the second venting hole is higher than the top of the vaporization core, so that the gas coming out laterally from the second venting hole directly mixes with the gas coming out upward from the middle opening of the annular plate. The height of all or part of the third venting hole is lower than the bottom of the lower sealing plate, and the third venting hole points to the middle of the lower surface of the lower sealing plate, so that the fuel entering from the fuel passage of the furnace head liner bounces off the lower surface of the lower sealing plate and mixes with the gas entering from the third venting hole in the mixing cavity. The mixed fuel and gas flow from the fourth venting hole to the middle opening of the annular plate after passing through the guide cavity.

[0005] Furthermore, it also includes a flame suppressor, which includes a third venting ring wall and an upper fixing plate. The upper fixing plate is connected to the top of the third venting ring wall. The side wall of the third venting ring wall is provided with a plurality of transverse fifth vent holes. The bottom of the third venting ring wall is placed on the annular plate. The third venting ring wall completely covers the middle opening of the annular plate. The upper fixing plate is used to guide the gas from the middle opening of the annular plate to the fifth vent holes. The fifth vent holes face the second vent holes so that the gas coming out of the fifth vent holes mixes with the gas coming out of the second vent holes.

[0006] Furthermore, the third ventilation ring wall is provided on the annular plate through a stepped structure at the bottom of the third ventilation ring wall, a fixed protrusion on the upper surface of the supporting ring plate, or a fixed groove on the upper surface of the supporting ring plate.

[0007] Furthermore, the pressure cap also includes a fourth vent ring wall and an upper sealing plate. The upper sealing plate is a fixing ring with an opening in the middle. The bottom of the fourth vent ring wall is connected to the inner edge of the fixing ring. The upper sealing plate is connected to the top of the fourth vent ring wall. The side wall of the fourth vent ring wall is provided with a plurality of transverse sixth vent holes.

[0008] Furthermore, a first positioning structure is provided between the burner cap and the vaporization core, and a second positioning structure is provided between the vaporization core and the furnace head liner. The first positioning structure is used to achieve circumferential positioning of the burner cap and the vaporization core, so that the rotation angle of the burner cap relative to the vaporization core is fixed. The second positioning structure is used to achieve circumferential positioning of the furnace head liner and the vaporization core, so that the rotation angle of the furnace head liner relative to the vaporization core is fixed. The burner cap is fixed in rotation angle relative to the furnace head liner by the first positioning structure and the second positioning structure, so that the fifth vent hole is positioned between two adjacent second vent holes.

[0009] Furthermore, a third positioning structure is provided between the burner cap and the inner liner of the furnace head. The third positioning structure is used to achieve circumferential positioning of the burner cap and the inner liner of the furnace head, so that the rotation angle of the burner cap relative to the inner liner of the furnace head is fixed. The burner cap is fixed in rotation angle relative to the inner liner of the furnace head by the third positioning structure, so that the fifth vent is aligned with the position between two adjacent second vents.

[0010] Furthermore, the second vent hole and the fifth vent hole are the same in number and located at the same height.

[0011] Furthermore, a fixing ring is provided in the middle of the annular plate, and the third venting ring wall is sleeved on the outer periphery of the fixing ring. The third venting ring wall and the first venting ring wall form an annular groove with a top opening. The gas from the fourth vent flows to the fifth vent. The gas from the fifth vent mixes with the gas from the second vent at the annular groove. The upper surface of the upper fixing plate is flush with the upper surface of the venting ring plate. The area of ​​a single sixth vent is smaller than the area of ​​a single fifth vent.

[0012] Furthermore, the mixing ring is bowl-shaped, wider at the top and narrower at the bottom. The sidewall of the mixing ring is provided with multiple rows of third vent holes. The height of the lower sealing plate is higher than the height of at least two rows of third vent holes. At least one of the top rows of third vent holes points to a fourth vent hole. The direction of the fourth vent hole is perpendicular to the second vent ring wall or the direction of the fourth vent hole is at a certain angle to the second vent ring wall, so that the gas passing through the fourth vent hole rotates inside the second vent ring wall. The direction of the second vent hole is perpendicular to the first vent ring wall or the direction of the second vent hole is at a certain angle to the first vent ring wall, so that the gas passing through the second vent hole rotates inside the first vent ring wall.

[0013] This utility model provides a stove body, which includes a stove platform and a burner structure according to any one of the present utility model, wherein the burner structure is disposed on the stove platform.

[0014] Unlike existing technologies, the above-mentioned technical solution forms a mixing chamber between the lower sealing plate and the inside of the mixing ring. Liquid fuel entering through the fuel through-hole of the burner liner bounces off the lower surface of the lower sealing plate and mixes with gas entering through the third vent in the mixing chamber. This achieves the first mixing of fuel entering through the fuel through-hole and air entering through the third vent. The mixed gas then flows through the guide chamber and from the second vent ring wall to the central opening of the annular plate. Gas exiting laterally from the second vent mixes directly with gas exiting upwards from the central opening of the annular plate, forming a second mixing. This two-stage mixing and combustion significantly improves fuel combustion efficiency. Furthermore, it eliminates the need for components like air filters, achieving good combustion with a simple structure and reducing burner costs. It can also be used in miniaturized burners.

[0064] Please see Figures 1 to 9 This utility model provides a burner structure 1, including a burner inner liner 2 and a burner outer shell 3. The burner inner liner 2 covers the burner outer shell 3. Both the burner inner liner 2 and the burner outer shell 3 have fuel passage holes 4 at their bottoms. The burner inner liner 2 includes, from top to bottom, a concentrating ring 20, a ventilation ring 21, a first ventilation ring wall 22, and a mixing ring 23. The term "ring" here does not refer to a thin sheet, but rather to a ring-shaped structure. The bottom of the concentrating ring 20 is connected to the outer edge of the ventilation ring 21, the top of the first ventilation ring wall 22 is connected to the inner edge of the ventilation ring 21, and the bottom of the first ventilation ring wall 22 is connected to the top of the mixing ring 23. The outer part of the ventilation ring 21 is disposed on the burner outer shell 3, such as through a stepped structure at the top of the burner outer shell 3 or through a stepped structure on the outer part of the ventilation ring 21. The venting ring 21 is provided with a plurality of vertical first vent holes 210, which penetrate the upper and lower surfaces of the venting ring 21. The side of the first venting ring wall 22 is provided with a plurality of horizontal second vent holes 220, which penetrate the left and right sides of the side wall of the first venting ring wall 22. The side of the mixing ring 23 is provided with a plurality of third vent holes 230, and the bottom of the mixing ring 23 is provided with a fuel passage hole 4.

[0065] The burner head structure 1 also includes a vaporization core 5, which is located in the middle of the burner head inner liner 2. The vaporization core 5 includes an annular plate 50, a second ventilation ring wall 51, and a lower sealing plate 52. Here, the ventilation ring wall refers to an annular barrel-shaped structure with ventilation holes on the sides and openings at the top and bottom. The annular plate 50 is an annular structure with an opening in the middle. The second ventilation ring wall 51 is connected to the inner edge of the annular plate 50, and the lower sealing plate 52 is connected to the bottom of the second ventilation ring wall 51. The side of the second ventilation ring wall 51 is provided with a plurality of transverse fourth ventilation holes 510. The annular plate 50 is placed on the lower inner side of the first ventilation ring wall 22 (for example, an inwardly extending step can be provided at the bottom of the first ventilation ring wall 22, and the annular plate 50 is placed on the step). The second ventilation ring wall 51 extends into the interior of the mixing ring 23, and a guide cavity 512 is formed between the outer wall of the second ventilation ring wall 51 and the upper part of the mixing ring 23. The sealing sheet 52 and the mixing ring 23 form a mixing chamber 523. The height of the second vent 220 is higher than the top of the vaporization core 5, so that the gas coming out laterally from the second vent 220 can directly mix with the gas coming out from the middle opening of the annular plate 50. It should be noted that direct mixing means that the gas coming out laterally from the second vent 220 can mix with the gas coming out from the middle opening of the annular plate 50 without being bounced back by other components to change the gas direction (i.e., remaining lateral), or in other words, the gas coming out laterally from the second vent 220 can flow directly to the top of the middle opening of the annular plate 50 without being completely blocked. The height of all or part of the third vent 230 (such as one or two rows of holes) is lower than the bottom of the lower sealing plate 52, and the third vent 230 (referring to the third vent 230 lower than the bottom of the lower sealing plate 52) points to the middle of the lower surface of the lower sealing plate 52, so that the fuel entering from the fuel passage 4 of the burner inner liner 2 bounces off the lower surface of the lower sealing plate 52 and mixes with the gas entering from the third vent 230 in the mixing chamber. The mixed fuel and gas flow from the fourth vent 510 to the middle opening of the annular plate 50 after passing through the guide chamber.

[0066] When this utility model is in operation, a fuel nozzle is first connected to the fuel through hole 4 of the burner shell 3, and a blower is connected to the bottom of the burner shell 3 (or the blower can be connected to the opening on the side wall of the burner shell 3). In this way, fuel can be sprayed out from the fuel nozzle, and the air from the blower can also enter the burner shell 3 from around the nozzle. The air from the blower can also enter the first vent hole 210, the second vent hole 220 and the third vent hole 230. Then, through the mixing chamber formed by the lower sealing plate 52 and the mixing ring 23, the liquid fuel (such as vegetable oil) entering from the fuel passage 4 of the burner liner 2 bounces off the lower surface of the lower sealing plate 52 and mixes with the gas entering from the third vent 230 in the mixing chamber. This achieves the first mixing of the fuel entering from the fuel passage 4 and the air entering from the third vent 230. After the mixed gas passes through the guide chamber, it flows from the second vent ring wall 51 to the middle opening of the annular plate 50. The gas coming out laterally from the second vent 220 mixes directly with the gas coming out upward from the middle opening of the annular plate 50, forming a second mixing. The two mixing and combustion can greatly improve the combustion effect of the fuel. Moreover, there are no wind screens or other components, and the simple structure can achieve good combustion effect, thus reducing the cost of the burner. The wind concentrator ring 20 and the first vent 210 realize the gathering and upward flow of the gas after the second mixing, avoiding flame dispersion and achieving better combustion effect. After combustion, the vaporization core 5 becomes hot. Then, the liquid fuel absorbs heat and vaporizes during the rebound process on the lower sealing plate 52 at the bottom of the vaporization core 5. In this way, the fuel becomes gas, which can mix better with air and burn better.

[0067] Furthermore, it also includes a flame suppressor 6, which includes a third venting ring wall 60 and an upper fixing plate 61. The upper fixing plate 61 is connected to the top of the third venting ring wall 60. The side wall of the third venting ring wall 60 is provided with a plurality of transverse fifth vent holes 601. The bottom of the third venting ring wall 60 is placed on the annular plate 50. The third venting ring wall 60 completely covers the middle opening of the annular plate 50, that is, the third venting ring wall 60 surrounds the outside of the middle opening of the annular plate 50. The upper fixing plate 61 is used to guide the gas from the central opening of the annular plate 50 to the fifth vent 601. The fifth vent 601 faces the second vent 220, allowing the gas from the fifth vent 601 to mix with the gas from the second vent 220. Here, "facing" does not mean completely opposite, but rather at approximately the same height. This allows the gas from the fifth vent 601 and the second vent 220 to mix above the annular plate 50. At this time, the upper fixing plate 61 is either completely or partially closed, allowing all or part of the gas from the central opening of the annular plate 50 to flow out through the fifth vent 601. The burner cap 6 guides the mixed gas from the central opening of the annular plate 50 to the transverse fifth vent 601, where it mixes with the second vent 220, resulting in more thorough mixing and further improving the combustion effect.

[0068] To achieve fixation between the third venting ring wall 60 and the annular plate 50, the third venting ring wall 60 is further provided on the annular plate 50 via a stepped structure 602 at its bottom, a fixing protrusion on the upper surface of the supporting ring plate, or a fixing groove on the upper surface of the supporting ring plate. The fixing protrusion can be multiple fixing posts (multiple fixing posts forming a circle) or a ring 501. The bottom of the third venting ring wall 60 is fixed around the fixing protrusion, and the bottom of the third venting ring wall 60 can be positioned inside or outside the fixing protrusion. The fixing groove can be multiple independent grooves (multiple grooves forming a circle) or an annular groove. The bottom of the third venting ring wall 60 is fixed by protrusions of the same number as the grooves placed within the grooves, or the bottom of the third venting ring wall 60 is directly positioned within the annular groove. In some embodiments, the fixing groove can also be stepped, and the bottom of the third venting ring wall 60 is fixed against the stepped surface, as long as fixation is achieved. This fixation ensures that the lateral relative position between the burner cap and the vaporizing core 5 remains unchanged, guaranteeing stable combustion. In some embodiments, a ring plate with an outer diameter similar to that of the ring plate 50 can also be connected to the bottom outer wall of the third ventilation ring wall 60. This fixation of the burner cap and the inner liner 2 of the burner head is achieved by fixing the relative position of the bottom ring plate and the first ventilation ring wall 22. Since the vaporizing core 5 is placed inside the inner liner 2 of the burner head, it is also fixed, thus achieving the fixation of the burner cap and the vaporizing core 5. The fixation in this invention does not mean that the two parts in contact are locked together, but rather that their relative positions are generally fixed after placement. They can sway slightly left and right, but their vertical positions remain essentially unchanged. Of course, the structure of the burner head in this application is generally made of cast iron or stainless steel and has a certain weight. Therefore, the vaporizing core 5 itself has a certain weight, ensuring that the vaporizing core 5 will not be lifted by the fuel ejected from the fuel passage 4.

[0069] Furthermore, the burner cap 6 also includes a fourth vent ring wall 62 and an upper sealing plate 63. The upper sealing plate 61 is a fixing ring plate 611 with a central opening. The bottom of the fourth vent ring wall 62 is connected to the inner edge of the fixing ring plate 611, and the upper sealing plate 63 is connected to the top of the fourth vent ring wall 62. The sidewall of the fourth vent ring wall 62 is provided with multiple transverse sixth vent holes 620. Through the fourth vent ring wall 62, which is smaller at the top than the third vent ring wall 60, combustion can also occur in the center of the burner cap 6, resulting in a wider range of combustion heat distribution. Furthermore, some of the mixed gas can be ejected and burned through the sixth vent holes 620, reducing the gas pressure exiting the fifth vent hole 601, lowering the noise of gas passing through the fifth vent hole 601, and achieving better combustion performance.

[0070] To achieve better mixing, a first positioning structure 7 is provided between the burner cap 6 and the vaporization core 5, and a second positioning structure 8 is provided between the vaporization core 5 and the inner liner of the burner head 2. The first positioning structure 7 is used to achieve circumferential positioning of the burner cap 6 and the vaporization core 5 (circumferential positioning in the horizontal plane, without rotation in the horizontal plane), so that the rotation angle of the burner cap 6 relative to the vaporization core 5 is fixed. The second positioning structure 8 is used to achieve circumferential positioning of the inner liner of the burner head 2 and the vaporization core 5, so that the rotation angle of the inner liner of the burner head 2 relative to the vaporization core 5 is fixed. The rotation angle of the burner cap 6 relative to the inner liner of the burner head 2 is fixed by the first positioning structure 7 and the second positioning structure 8, so that the fifth vent 601 is aligned with the position between the two adjacent second vents 220. This avoids the second vent 220 and the fifth vent 601 being directly opposite each other, but instead they are offset at a certain angle. The gas from the fifth vent 601 and the second vent 220 can first flow into the groove formed between the first vent ring wall 22 and the third vent ring wall 60 before mixing, so that the mixed gas will not be chaotic, the flame produced is uniform, and the combustion effect is better.

[0071] In some embodiments, a third positioning structure 9 is provided between the burner cap 6 and the inner liner of the burner head 2. The third positioning structure 9 is used to achieve circumferential positioning of the burner cap 6 and the inner liner of the burner head 2, so that the rotation angle of the burner cap 6 relative to the inner liner of the burner head 2 is fixed. The rotation angle of the burner cap 6 relative to the inner liner of the burner head 2 is fixed by the third positioning structure 9 so that the fifth vent 601 is aligned with the position between two adjacent second vents 220. The third positioning structure 9 can be a vertical groove formed on the first vent ring wall 22 of the burner cap 6, and a positioning rod can be set on the side wall of the burner cap 6 and placed in the vertical groove to achieve circumferential fixation. Of course, other fixing methods can also be used, as long as the relative rotation angle can be fixed. The fixation using the third positioning structure 9 is simpler, and it avoids the second vent 220 and the fifth vent 601 being directly opposite each other, but instead they are offset at a certain angle. The gas from the fifth vent 601 and the second vent 220 can first flow into the groove formed between the first vent ring wall 22 and the third vent ring wall 60 before mixing, so that the mixed gas will not be chaotic, the flame produced is uniform, and the combustion effect is better.

[0072] Preferably, the second vent 220 and the fifth vent 601 are the same in number and positioned at the same height. This results in more uniform mixing and better performance.

[0073] In a preferred embodiment, a fixing ring 501 is provided at the middle position of the annular plate 50, and the third venting ring wall 60 is sleeved on the outer periphery of the fixing ring 501 to fix them and prevent them from moving left and right. The third venting ring wall 60 and the first venting ring wall 22 form an annular groove 6022 with a top opening. The gas from the fourth vent 510 flows to the fifth vent 601, and the gas from the fifth vent 601 mixes with the gas from the second vent 220 at the annular groove 6022. The upper surface of the upper fixing plate 61 is flush with the upper surface of the venting ring plate 21, so that the heights on both sides of the annular groove are the same, and the mixed gas can disperse evenly on both sides, making the gas dispersion more stable. The area of ​​a single sixth vent 620 is smaller than the area of ​​a single fifth vent 601. In this way, most of the gas can flow out through the fifth vent 601 to achieve the main mixing and combustion, and then a small portion of the gas comes out through the sixth vent 620 to achieve the combustion of the intermediate flame. This allows combustion to occur even in the center of the burner cap 6, resulting in a wider distribution of combustion heat.

[0074] The mixing ring 23 can be cylindrical. In some embodiments, the mixing ring 23 is bowl-shaped, wider at the top and narrower at the bottom. Multiple rows of third vent holes 230 are provided on the sidewalls of the mixing ring 23. The height of the lower sealing plate 52 is higher than the height of at least two rows of third vent holes 230. This allows more air to enter the mixing chamber for mixing, improving the mixing and combustion effects. At least one row of third vent holes 230 at the top points towards the fourth vent hole 510, guiding the mixed gas into the fourth vent hole 510, thus enhancing both the mixing effect and providing guidance. The fourth vent 510 is perpendicular to the second vent ring wall 51, or the direction of the fourth vent 510 is at a certain angle to the second vent ring wall 51, so that the gas passing through the fourth vent 510 rotates inside the second vent ring wall 51. Similarly, the second vent 220 is perpendicular to the first vent ring wall 22, or the direction of the second vent 220 is at a certain angle to the first vent ring wall 22, so that the gas passing through the second vent 220 rotates inside the first vent ring wall 22. This "certain angle" is not a 90-degree angle, but rather an angle formed by its projection onto the horizontal plane, such as between 40 and 70 degrees, all in the same direction. This creates rotating gas and improves the mixing effect.
