Description

Technical Field

[0001] This utility model relates to the field of burner technology, and in particular to a burner and stove body with air guide vanes. Background Technology

[0002] A burner is used to mix and burn fuel gas or liquefied gas with air to produce a high-temperature flame for heating or cooking. Existing bottom-intake burners allow air to enter from the bottom of the burner, mix with fuel, and then burn on the burner surface. The burner includes components such as a shell, inner liner, nozzle, and air guide vanes. For example, in a utility model patent application filed prior to this application, patent publication number CN220287517U, a burner structure and stove body for improving vaporization, the air guide vanes in that patent have a sheet-like structure. External air interacts with the air guide vanes from the bottom of the shell, dispersing the air into the interior of the shell. This dispersed air then mixes with fuel injected through the nozzle, forming a mixed burner, ultimately achieving complete combustion of the fuel.

[0003] However, during actual use, the applicant found that the airflow inside the casing was turbulent, the fuel and air were not mixed evenly, and the flame after combustion would flicker unevenly, resulting in an unsatisfactory combustion effect. Utility Model Content

[0004] Therefore, a stove body is needed to solve the problems of turbulent airflow, uneven mixing of fuel and air, uneven flame flickering after combustion, and unsatisfactory combustion effect caused by the dispersed air inside the existing outer shell.

[0005] To achieve the above objectives, this utility model provides a burner with an air guide vane, including an air guide vane, a housing, and a fuel nozzle. A nozzle fixing hole is provided at the center of the bottom of the housing. The fuel nozzle passes through the nozzle fixing hole and is fixed to the bottom of the housing. An air inlet pipe is provided at the bottom of the housing, located outside the nozzle fixing hole. Multiple air inlets are provided between the air inlet pipe and the nozzle fixing hole at the bottom of the housing. The air guide vane is located inside the housing and is fitted around the outer periphery of the fuel nozzle. The air guide vane includes a circular plate-shaped bottom and a cylindrical sidewall. The cylindrical sidewall is positioned above the outer periphery of the plate-shaped bottom and protrudes above the plate-shaped bottom. The plate-shaped bottom is directly above the air inlets. The fuel nozzle is fixed to the nozzle fixing hole by a thread or by a nut.

[0006] Furthermore, the air guide vane is used to guide the air from the air inlet upward along the side wall of the cylinder.

[0007] Furthermore, the fuel nozzle includes a nozzle head and a base tube. The base tube passes through the nozzle fixing hole and is fixed to the bottom of the housing. The top of the base tube has a fixing groove for accommodating the air guide plate. The side wall of the fixing groove is smooth or has a thread for connecting with the air guide plate. The air guide plate is placed on the fixing groove. The nozzle head is screwed into the top inner wall of the base tube by the thread. The side wall of the nozzle head covers the air guide plate.

[0008] Furthermore, the sheet-like bottom has multiple ventilation holes arranged in a circle around the center of the sheet-like bottom, or the sheet-like bottom is completely closed.

[0009] Furthermore, an oil drain hole is provided on the side wall of the cylinder or the bottom of the sheet, and the oil drain hole is connected to an oil drain pipe, which is connected to the outside of the outer shell.

[0010] Furthermore, it also includes a wind screen, a flame suppressor, a vaporization chamber, and an inner liner. The middle part of the inner liner extends outward to form a first step. The inner liner is placed on the top of the outer shell through the first step. The portion of the first step inside the outer shell has a first through hole. The lower part of the inner liner is placed inside the outer shell. The bottom surface of the inner liner has a fuel through hole facing the fuel nozzle. The vaporization chamber, flame suppressor, and wind screen are placed inside the inner liner in sequence from bottom to top. The flame suppressor is placed on the vaporization chamber. The bottom of the vaporization chamber has a second through hole and the top is open. The top of the flame suppressor is closed and the upper side has multiple third through holes arranged horizontally around it. The bottom of the wind screen is placed above the first step. The bottom of the wind screen has a fourth through hole pointing upward. The bottom of the wind screen and the fourth through hole are placed below the plane where the third through hole is located. The fourth through hole surrounds the outside of the third through hole.

[0011] Furthermore, the fire suppressor has a lower cylindrical part, which is disposed on the top of the fire suppressor and the upper part of the lower cylindrical part is positioned above the first step. The upper part of the fire suppressor is inwardly contracted to form a second step. The plane containing the third through hole is positioned above the second step. The bottom of the air mesh is disposed on the first step, and the top of the air mesh covers the top of the inner liner.

[0012] Furthermore, the second step has an outward annular protrusion or an annular groove, and the bottom of the air mesh is placed on the annular protrusion or in the annular groove.

[0013] Furthermore, the bottom of the wind net is a sheet-like ring, and the fourth through hole is placed on the sheet-like ring of the wind net, with the upper surface of the sheet-like ring flush with the upper surface of the second step.

[0014] This utility model also provides a stove body, including a stove body support and a burner disposed in the stove body support, wherein the burner is the burner described in any one of the embodiments of this utility model.

[0015] Unlike existing technologies, the above-mentioned solution connects the air inlet duct to a fan during use. The fan blows air into the air inlet duct, and the air then enters the outer casing through multiple air inlets. After passing the bottom of the casing, the airflow is redirected by the deflector plates directly above the air inlets, causing the air to flow around the bottom of the casing. The air then flows upwards. During this upward flow, the cylindrical sidewall guides the airflow, causing it to travel a short distance upwards along the outer sidewall. At this point, the airflow is relatively stable. Then, due to inertia, the airflow maintains a certain degree of stability, reducing turbulence within the casing. This relatively stable airflow then mixes with the fuel injected from the fuel nozzle, resulting in a more uniform mixture before combustion. The resulting flame is more stable overall, without uneven flickering, thus improving combustion efficiency. Attached Figure Description

[0046] Please see Figures 1 to 12 This embodiment provides a burner 1 with an air guide vane 2, including the air guide vane 2, a housing 3, and a fuel nozzle 4. A nozzle fixing hole 5 is provided at the center of the bottom of the housing 3. The fuel nozzle 4 passes through the nozzle fixing hole 5 and is fixed to the bottom of the housing 3. An air inlet pipe 6 is provided at the bottom of the housing 3, located outside the nozzle fixing hole 5. Multiple air inlets 7 are provided at the bottom of the housing 3 between the air inlet pipe 6 and the nozzle fixing hole 5. The air guide vane 2 is disposed inside the housing 3 and is fitted around the outer periphery of the fuel nozzle 4. The air guide vane 2 includes a circular, sheet-like bottom 21 and a cylindrical sidewall 22. Here, "fitted" means that the air guide vane 2 has a central hole 23, which is used to fit around the outer periphery of the fuel nozzle 4. To achieve a cylindrical shape, the thickness of the cylindrical sidewall 22 is less than its height. The thickness of the cylindrical sidewall 22 can be the same as the thickness of the sheet-like bottom 21. The air guide vane 2 can be formed by stamping a sheet material or by welding the sheet-like bottom 21 to the cylindrical sidewall 22. The cylindrical sidewall 22 is placed on the outer periphery of the sheet-like bottom 21, and the cylindrical sidewall 22 protrudes from the top of the sheet-like bottom 21. The sheet-like bottom 21 is directly above the air inlet 7. The fuel nozzle 4 is fixed to the nozzle fixing hole 5 by a thread between them or by a nut 8 on the nozzle fixing hole 5.

[0047] In use, the bottom of the fuel nozzle 4 is connected to the fuel feed pipe 60, which can be connected to the bottom of the fuel nozzle via the side wall of the air inlet pipe 6. The fuel nozzle 4 has nozzle holes inside, from which fuel is ejected. The air inlet pipe 6 is connected to a blower, which blows air into the air inlet pipe 6, and then the air enters the interior of the outer casing 3 through multiple air inlets 7. After passing the bottom of the outer casing 3, the airflow changes direction because the plate-shaped bottom 21 of the air guide vane 2 is directly above the air inlet 7, causing the air to flow around the bottom of the outer casing 3. Then it flows upwards. During this upward flow, the cylindrical side wall 22 guides the airflow, causing it to travel a short distance upwards along the outer side of the cylindrical side wall 22. At this point, the airflow is relatively stable. Then, due to inertia, the airflow maintains a certain degree of stability, reducing turbulence within the outer casing 3. This relatively stable airflow mixes with the fuel sprayed from fuel nozzle 4, resulting in a more uniform mixture before combustion. The resulting flame is more stable overall, without uneven fluctuations, thus improving the combustion effect.

[0048] In this invention, the air guide vane 2 also serves to disperse airflow outwards. In a preferred embodiment, the air guide vane 2 guides the airflow from the air inlet 7 upwards along the cylindrical sidewall 22. This upward guidance via the cylindrical sidewall 22 reduces airflow turbulence, thereby improving combustion efficiency.

[0049] To achieve a combined fixation of the fuel nozzle 4 and the air guide vane 2, the fuel nozzle 4 includes a nozzle head 41 and a base tube 42, which is used to connect to the fuel inlet pipe. The base tube 42 passes through the nozzle fixing hole 5 and is fixed to the bottom of the housing 3. It can be directly connected by threads or locked to the bottom of the housing 3 by a nut 8. The top of the base tube 42 has a fixing groove 43 for accommodating the air guide vane 2. The sidewall of the fixing groove 43 is smooth (so the middle hole of the air guide vane 2 can be directly fitted onto the fixing groove 43) or has threads for connecting to the air guide vane 2 (so the threads on the sidewall can be screwed into the fixing groove 43). The threads of the fixing groove 43 reinforce the fixation of the air guide vane 2. The air guide vane 2 is placed on the fixing groove 43, and the nozzle head 41 is screwed into the top inner wall of the base tube 42, with the sidewall of the nozzle head 41 covering the air guide vane 2. The sidewall of the nozzle head 41 mentioned here refers to the side portion of the nozzle head 41, which only needs to cover the air guide vane 2. This covering serves to fix the air guide vane 2 in the fixing groove 43, preventing it from coming out. For example, the diameter of the top sidewall of the nozzle head 41 can be set larger than the diameter of the central hole 23 of the air guide vane 2. This allows for modular assembly. During assembly, first, the bottom tube 42 is passed through the nozzle fixing hole 5 and then fixed to the bottom of the outer casing 3. Then, the air guide vane 2 is fixed into the fixing groove 43 at the top of the bottom tube 42.

[0050] Furthermore, the plate-shaped bottom 21 may have multiple ventilation holes 24 arranged in a circle around its center, or the plate-shaped bottom 21 may be completely closed. The ventilation holes 24 allow some air from the bottom to directly enter the fuel nozzle 4 for mixing, thus improving mixing efficiency. If completely closed, the airflow is guided by the cylindrical sidewall 22 into the outer shell 3 for mixing, resulting in a more uniform mixing.

[0051] In some embodiments, because the cylindrical sidewall 22 protrudes above the plate-shaped bottom 21, making the air guide vane 2 a bowl-shaped groove, some liquid fuel may accumulate on the plate-shaped bottom 21 and cannot be discharged, potentially causing it to coke due to the high temperature of the burner 1. To improve this situation, the cylindrical sidewall 22 or the plate-shaped bottom 21 is provided with an oil drain hole 25. This allows the liquid fuel to drain from the oil drain hole 25, preventing excessive accumulation on the plate-shaped bottom 21. The oil drain hole is connected to an oil drain pipe, which can be directly connected or connected via a funnel structure. The oil drain pipe connects to the outside of the outer casing and can be connected to the fuel tank, enabling fuel recovery.

[0052] In some embodiments, the system further includes a ventilation grille 10, a flame suppressor 20, a vaporization chamber 30, and an inner liner 40. The inner liner 40 has a first step 401 extending outward from its center (here, "step" refers to the laterally extending portion). The inner liner 40 is placed on top of the outer shell 3 via the first step 401. A first through-hole 402 is provided in the portion of the first step 401 inside the outer shell 3, and the lower part of the inner liner 40 is placed inside the outer shell 3. Thus, air inside the outer shell 3 can flow to the upper part of the inner liner 40 through the first through-hole 402. The inner liner 40 has a fuel through-hole 403 on its bottom surface facing the fuel nozzle 4. The vaporization liner 30, the flame suppressor 20, and the air mesh 10 are placed inside the inner liner 40 in sequence from bottom to top. The flame suppressor 20 is located on the vaporization liner 30. The bottom of the vaporization liner 30 has a second through-hole 301 and the top is open. The top 204 of the flame suppressor 20 is closed, and the upper side has multiple horizontally arranged third through-holes 201. The bottom of the air mesh 10 is located above the first step 401. The bottom of the air mesh 10 has an upward-facing fourth through-hole 105, allowing air passing through the first through-hole 402 to flow to the fourth through-hole 105. The bottom of the air mesh 10 and the fourth through-hole 105 are located below the plane of the third through-hole 201, and the fourth through-hole 105 surrounds the outside of the third through-hole 201. In this embodiment, the fuel from the fuel nozzle 4 is mixed with the air inside the outer casing 3 for the first time. Under the action of the ignition needle 50, a portion of the mixed gas (fuel and air) is burned. The remaining fuel, mixed with some air, enters the inner liner 40, and then enters the vaporization liner 30 through the second through hole 301. Inside the vaporization liner 30, the liquid fuel is fully vaporized and sprayed out laterally through the third through hole 201. Since the fourth through hole 105 is located below the plane of the third through hole 201 and surrounds the outside of the third through hole 201, the gas sprayed out of the third through hole 201 will be above the fourth through hole 105. In this way, the air sprayed upward from the fourth through hole 105 will directly mix more fully with the gas in the third through hole 201, improving the mixing effect of the gas, and then combustion, thus improving the combustion effect.

[0053] In the above embodiments, it is sufficient that the fourth through hole 105 is located above the first step 401, that is, there is a certain distance between the fourth through hole 105 and the first step 401 so that air passing through the first through hole 402 can flow to the fourth through hole 105. For example, the height of the vaporization chamber 30 can be increased so that the top of the vaporization chamber 30 is higher than the first step 401, and then the bottom of the flame suppressor 20 and the air mesh 10 set on the vaporization chamber 30 can be above the first step 401. In some embodiments, this can also be achieved using the flame suppressor 20. The flame suppressor 20 has a lower cylindrical portion 202, which is positioned on top of the flame suppressor 20, with its top surface above the first step 401. Specifically, the top surface of the lower cylindrical portion 202 is higher than the first step 401. The upper part of the flame suppressor 20 tapers inward to form a second step 203 (here, "step" refers to a laterally extending portion). The plane containing the third through hole 201 is positioned above the second step 203. The bottom of the air mesh 10 is positioned on the first step 401, and the top of the air mesh 10 covers the top of the inner liner 40 (the top of the air mesh 10 and the top of the inner liner 40 form a certain seal, ensuring that air can be ejected through the fourth through hole 105). Thus, by raising the second step 203 through the lower cylindrical portion 202, the bottom of the air mesh 10 on the second step 203 is positioned above the first step 401, allowing air passing through the first through hole 402 to flow to the fourth through hole 105. Meanwhile, the lower part 202 of the cylinder increases the space of the vaporization chamber 30, which is conducive to the further vaporization of liquid fuel in the vaporization chamber 30.

[0054] To achieve a fixed relationship between the bottom of the air mesh 10 and the first step 401, the second step 203 has an outward annular protrusion 205 or an annular groove, and the bottom of the air mesh 10 is placed on the annular protrusion 205 or in the annular groove. Figure 11 and Figure 12 As shown, the second step 203 has an annular protrusion 205, and the bottom of the rear air mesh 10 is provided with a corresponding annular groove 107, which is placed on the annular protrusion 205. This allows for a tighter fit, reduces air leakage between the two, and prevents gas from leaking out from the area between them and affecting the stability of the airflow.

[0055] Furthermore, the bottom of the air mesh 10 is a sheet-like ring 104, and the fourth through hole 105 is placed on the sheet-like ring 104 of the air mesh 10. The upper surface of the sheet-like ring 104 is flush with the upper surface of the second step 203. The sheet-like ring 104 and the second step 203 form a plane, which facilitates the arrival of the gas ejected from the third through hole 201 onto the fourth through hole 105, and facilitates the mixing of the gas.

[0056] In a specific embodiment, the air mesh 10 may further include an upper ring wall 101 and a lower ring wall 102. Both the upper ring wall 101 and the lower ring wall 102 are cylindrical structures with openings at the top and bottom, and their heights can be adapted and adjusted according to the internal space of the burner 1 and the size of the flame suppressor 20. The upper edge of the upper ring wall 101 extends horizontally outward with an extension portion 103. The extension portion 103 is a limiting structure protruding from the outside of the upper ring wall 101. The extension portion 103 is used to fit and limit the burner 1 housing. It can be formed by a combination of multiple protrusions or a complete planar circular ring structure, as long as it can fit into the inner wall protrusion structure of the burner 1 housing, thereby limiting the air mesh 10 to a specified height within the burner 1 housing. For example, an annular protrusion is provided on the upper part of the inner wall of the burner 1 shell. When the air mesh 10 is inserted into the burner 1 shell from top to bottom, the lower part of the outer extension 103 is supported by the annular protrusion, and the outer periphery is limited by the inner wall of the burner 1 shell, making the air mesh 10 more stable inside the burner 1 shell. Since the outer extension 103 and the annular protrusion are vertically stacked and supported, the gas in the furnace is not easy to overflow through this point, thus ensuring the airtightness. The lower edge of the lower ring wall 102 extends horizontally inward with a plate-shaped ring 104. The plate-shaped ring 104 is a planar ring structure, and its inner diameter can be adapted and adjusted according to the size of the pressure cap 20. When the air mesh 10 and the pressure cap 20 are both installed in the burner 1 shell, the inner side wall of the plate-shaped ring 104 and the outer side wall of the pressure cap 20 should fit as closely as possible to improve the airtightness. The inner diameter of the lower ring wall 102 is smaller than that of the upper ring wall 101. The lower edge of the upper ring wall 101 and the upper edge of the lower ring wall 102 are connected by a horizontally arranged structural ring 106. The structural ring 106 is provided with multiple fourth through holes 105. By contracting the lower ring wall 102 inward, an exhaust chamber is formed between the lower ring wall 102, the structural ring 106, and the outer shell of the burner 1. This chamber is connected to the vaporization chamber inside the burner 1. The gas can enter the exhaust chamber and be output upward through the fourth through holes 105 on the structural ring 106, thereby forming the flame on the outer ring of the burner 1 and improving the heating efficiency.

[0057] This utility model can be sold as a stove body; that is, this utility model also provides a stove body, including a stove body support and a burner disposed within the stove body support, wherein the burner is the burner described in any one of the embodiments of this utility model. This way, the burner is fixed to the stove body support to form a single unit, and pots can be directly placed on it for heating, facilitating sale and use.

[0058] In the above embodiments, it should be noted that each component can be made of a metal material through die casting or welding, such as stainless steel, cast iron, or aluminum alloy. Preferably, the air mesh 10, inner liner, and vaporization liner can be made of cast iron, which has good heat insulation performance and durability, making it suitable for use in the burner 1.
