Description

Technical Field

[0001] This utility model discloses a novel energy-saving fuel stove core, which particularly relates to the field of stove cores. Background Technology

[0002] Fuel for oil-fired stoves is mostly vegetable oil, waste oil, or alcohol-based fuel. However, its main drawback is that the fuel has a high ignition point and incomplete combustion. To ensure the complete combustion of alcohol-based fuel, the fuel must first be fully vaporized and then fully mixed with air before combustion. This process is complex, time-consuming, labor-intensive, energy-intensive, and costly, raising the barrier to popularization for the general public. Current technology cannot achieve sufficient mixing of air and oil, resulting in incomplete combustion, air pollution, and problems such as oil dripping and gumming, which reduce the product's lifespan and increase operating costs. Utility Model Content

[0003] This utility model discloses a novel energy-saving fuel stove core, which consists of a concentrator, an oil injection device, an air-oil premixing device, an ignition needle, a flame-concentrating air-oil disc, and a flame-pressurizing cap. Through the cooperation of these components, the air and oil within the stove core are premixed, and the premixed air and oil are precisely pressurized to aid oxygenation, guide flow, and vaporize, achieving efficient fuel vaporization and complete combustion. This avoids the phenomenon of dripping and gelling due to incomplete vaporization. This novel energy-saving fuel stove core, through its simple structure, enables efficient fuel combustion and improves thermal energy utilization, thereby achieving energy savings and extending the lifespan of the stove core.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A novel energy-saving fuel stove core, characterized by comprising: a concentrating bowl, an oil injection device, an oil-air premixing device, an ignition needle, a concentrating oil-air plate, and a flame suppressor cap, wherein the oil injection device and the ignition needle are mounted on the concentrating bowl and fixed by nuts, the oil-air premixing device is placed inside the concentrating bowl, so that the oil injection device and the ignition needle pass through the oil-air premixing device and are placed inside the oil-air premixing device, the bottom of the oil-air premixing device is connected to the nut that fixes the oil injection device and the ignition needle, so that the oil-air premixing device... There is a space between the bottom of the oil premixing device and the bottom of the air-concentrating bowl. The air-oil premixing device is fixed inside the air-concentrating bowl. The fire-concentrating air-oil plate is placed on the air-concentrating bowl, and the fire-pressing cap is placed on the fire-concentrating air-oil plate. The air-concentrating bowl is provided with an air inlet channel and an air inlet. The oil spraying device is provided with an oil inlet pipe and an oil nozzle. The air-oil premixing device is provided with a wind shield, a first ventilation hole, a second ventilation hole, and a third ventilation hole. The fire-concentrating air-oil plate is provided with a fire-concentrating port, a diversion groove, and an air eye. The fire-pressing cap is provided with a correction ring and a fire eye.

[0005] The air-gathering bowl has a spiral air inlet design, which can guide the airflow and allow the air to spiral into the space between the air-oil premixing device and the air-gathering bowl, rapidly increasing the pressure in that space.

[0006] In the aforementioned premixed air device, the first ventilation hole is located on the wind shield plate, and the wind shield plate is connected to the inner wall of the wind concentrator, dividing the space between the wind concentrator and the premixed air device into upper and lower parts. The second ventilation hole is located on the side wall of the premixed air device, below the wind shield plate, and is evenly distributed around the side wall of the premixed air device. The third ventilation hole is located on the side wall of the premixed air device, above the wind shield plate, and is evenly distributed around the side wall of the premixed air device.

[0007] The upper opening of the premixed oil device is connected to the bottom of the oil pan, and the part of the concentrator is placed inside the premixed oil device, while the part of the oil nozzle is placed inside the concentrator.

[0008] In the aforementioned premixed air device, the total ventilation volume of the first ventilation hole is 19 times that of the second ventilation hole. The size of the second ventilation hole is the same as that of the third ventilation hole. When the total ventilation volume of the first ventilation hole is in a ratio of 19 to 1 with the total ventilation volumes of the second and third ventilation holes, the fuel and air mix and provide oxygen in the premixed air device. After ignition, the mixture can be completely sent into the ignition port, avoiding situations where the fuel cannot burn completely due to excessive upward airflow or insufficient oxygen supply, resulting in gumming, oil dripping, air pollution, and the generation of irritating odors.

[0009] The optimal value is that the total ventilation volume of the first ventilation hole on the premixed oil device is 19:1 to the total ventilation volume of the second and third ventilation holes. A ratio greater than 19:1 or less than 19:1 can also achieve a similar effect, and both are within the protection scope of this technical solution.

[0010] The wind shield on the wind oil premixing device is provided with a first ventilation hole, and the wind shield is connected to the inner wall of the wind concentrator bowl. The purpose is to control the ventilation volume. This solution is only one technical solution. The purpose of controlling the ventilation volume can also be achieved by increasing the distance between the wind shield and the inner wall of the wind concentrator bowl. Both are within the protection scope of this technical solution.

[0011] The ignition needle is placed within the space formed by the premixing device and the concentrating oil plate, which avoids carbon buildup and short circuits caused by dripping oil or splashing water during cooking or cleaning of the fuel stove. The ignition needle has a dual-sided ignition design, with two ignition needles placed on the left and right sides of the fuel injector respectively. The ignition needle can ignite the fuel sprayed from the fuel injector from both sides, which can ensure that the fuel is fully ignited and improve the combustion efficiency of the fuel.

[0012] The purpose of the dual ignition needles, which ignite simultaneously on both sides of the fuel injector, is to ensure that the fuel injected by the fuel injector can be fully ignited. The technical solution is multi-point ignition. The dual ignition needle design is the best technical solution based on a combination of cost and effect. Designs with 3, 4, 5, 6, or other multiple ignition needles can also achieve similar or better results, and all of them fall within the protection scope of this technical solution.

[0013] The flame-gathering nozzle on the flame-gathering oil plate is a trapezoidal structure that gradually narrows upwards, which allows the air and fuel oil to gradually accelerate their fusion and combustion from bottom to top, while simultaneously increasing the pressure of the fuel oil from bottom to top.

[0014] The drainage channels on the fire-gathering oil pan are inclined channels, located on the outside of the fire-gathering port. All drainage channels are inclined to the same side and are evenly distributed around the outside of the fire-gathering port. This prevents the burning fuel from directly scorching the fire-gathering oil pan when it sprays out through the drainage channels, thus avoiding heat waste and reducing the service life of the fire-gathering oil pan.

[0015] The air vents on the fire-gathering oil plate connect the internal space of the air-gathering bowl and the upper space of the fire-gathering oil plate. The air vents are evenly distributed around the inner wall of the fire-gathering oil plate to assist oxygenation and correct the direction of combustion of the fuel entering the fire-gathering oil plate.

[0016] The corrective ring on the burner cap is located at the center of the burner cap, directly opposite the ignition port. The inner diameter of the corrective ring is larger than the outer diameter of the upper end of the ignition port. Under the action of the corrective ring, the burning fuel can pass through the gap between the ignition port and the corrective ring at a stable pressure and enter the space formed by the outer wall of the ignition port and the inner wall of the burner cap in a spray manner, thereby accelerating the vaporization and combustion of the fuel.

[0017] The flame holes on the flame cap are located on the side wall of the flame cap and are evenly distributed around the side wall. The flame holes are inclined towards the cross-section of the side wall of the flame cap, and the inclination direction is consistent with the inclination direction of the diversion groove. The burning fuel is sprayed out through the flame holes and the diversion groove, forming a double-layer flame in the flame-gathering oil plate, so that the burning fuel can fully contact the air, further accelerating the vaporization and combustion speed.

[0018] In practice Fuel enters the fuel injection device through the fuel inlet pipe and is sprayed out from the nozzle. It is simultaneously ignited by the ignition needle from both sides. At the same time, air enters through the air inlet channel, swirling through the air inlet into the space between the air collector and the fuel-air premixing device, causing a rapid increase in pressure within this space. Then, a portion of the air passes through the second vent into the fuel-air premixing device, stabilizing the pressure within it and providing oxygen and upward thrust to the fuel sprayed from the nozzle. Another portion of the air passes through the first vent into the space above the wind shield, and then through the third vent into the fuel-air premixing device, providing oxygen to the fuel sprayed from the nozzle and concentrating the fuel towards the center to prevent it from escaping and causing dripping or sticking inside the burner core. The burning fuel, pre-mixed and ignited in the fuel-air premixing device, enters the concentrator port, which gradually narrows from bottom to top, causing the burning fuel inside to gradually increase in pressure before being sprayed out. After being blocked by the pressure cap and the straightening ring, some of the burning fuel is reflected down and forms convection with the fuel in the nozzle, further dispersing, vaporizing and burning the fuel. The partially burned fuel passes through the gap between the straightening ring and the nozzle and is sprayed into the space formed by the outer wall of the concentrator and the inner wall of the pressure cap to continue burning, continuously heating the pressure cap. Then, the burning fuel is sprayed out through the guide groove and the flame hole in a rotating manner, continuing to burn in the space formed by the concentrator and the side wall of the pressure cap. The fuel sprayed out in a rotating manner through the guide groove and the flame hole forms a double flame. The combustion of the double flame increases the contact area between the fuel and air during combustion, resulting in more complete combustion. At the same time, the air in the air concentrator passes through the air hole and enters the space formed by the concentrator and the side wall of the pressure cap, applying upward pressure to the burning fuel and assisting oxygenation, while reducing direct burning of the side wall of the concentrator, improving heat energy utilization and increasing the service life of the concentrator, thus reducing use and maintenance costs.

[0019] When this new type of energy-saving fuel stove core is working, the ignited fuel is quickly dispersed, pressurized, oxygenated, and vaporized inside the core. At the same time, by continuously heating the components inside the fuel stove core, the fuel is kept in a high-temperature environment, thereby achieving the effects of rapid fuel vaporization and efficient combustion.

[0025] The beneficial effects of adopting the above technical solution are as follows: The new energy-saving fuel stove core has a simple design and low production cost.

[0028] The following is in conjunction with the appendix Figure 1-5 This invention provides a preferred embodiment of a novel energy-saving fuel-fired stove core.

[0029] A novel energy-saving fuel stove core, characterized by comprising: a concentrating bowl 1, an oil injection device 2, an oil-air premixing device 3, an ignition needle 4, a concentrating oil-air plate 5, and a flame suppressor 6. The oil injection device 2 and the ignition needle 4 are mounted on the concentrating bowl 1 and secured with nuts. The oil-air premixing device 3 is placed inside the concentrating bowl 1, with the oil injection device 2 and the ignition needle 4 passing through it. The bottom of the oil-air premixing device 3 is connected to the nuts securing the oil injection device 2 and the ignition needle 4, leaving a gap between the bottom of the oil-air premixing device 3 and the bottom of the concentrating bowl 1. In this configuration, the premixed air-oil device 3 is fixed inside the air-collecting bowl 1, the fire-collecting air-oil plate 5 is placed on the air-collecting bowl 1, and the fire-pressing cap 6 is placed on the fire-collecting air-oil plate 5. The air-collecting bowl 1 is provided with an air inlet channel 11 and an air inlet 12. The oil spraying device 2 is provided with an oil inlet pipe 21 and an oil spray nozzle 22. The premixed air-oil device 3 is provided with a wind shield 31, a first ventilation hole 32, a second ventilation hole 33, and a third ventilation hole 34. The fire-collecting air-oil plate 5 is provided with a fire-collecting port 51, a diversion groove 52, and an air eye 53. The fire-pressing cap 6 is provided with a correction ring 61 and a fire eye 62.

[0030] The air inlet 12 of the air-gathering bowl 1 is designed with a spiral structure, which can guide the air direction and allow the air to spiral into the space between the air-oil premixing device 3 and the air-gathering bowl 1, thereby rapidly increasing the pressure in the space.

[0031] In the aforementioned premixed oil device 3, the first ventilation hole 32 is provided on the wind shield 31. The wind shield 31 is connected to the inner wall of the wind concentrator 1, dividing the space between the wind concentrator 1 and the premixed oil device 3 into upper and lower parts. The second ventilation hole 33 is provided on the side wall of the premixed oil device 3, located below the wind shield 31, and is evenly distributed around the side wall of the premixed oil device 3. The third ventilation hole 34 is provided on the side wall of the premixed oil device 3, located above the wind shield 31, and is evenly distributed around the side wall of the premixed oil device 3.

[0032] The upper opening of the premixed oil device 3 is connected to the bottom of the oil pan. Part of the concentrator 51 is placed inside the premixed oil device 3, and part of the injector 22 is placed inside the concentrator 51.

[0033] In the aforementioned premixed air device 3, the total ventilation volume of the first ventilation hole 32 is 19 times that of the second ventilation hole 33. The size of the second ventilation hole 33 is the same as that of the third ventilation hole 34. When the total ventilation volume of the first ventilation hole 32 is in a ratio of 19 to 1 with the total ventilation volumes of the second ventilation hole 33 and the third ventilation hole 34, the fuel and air mix in the premixed air device 3 to provide oxygen. After ignition, the mixture can be completely sent into the ignition port 51, thus avoiding the situation where the fuel cannot burn completely due to excessive upward airflow or insufficient oxygen supply, resulting in gumming, oil dripping, air pollution, and the generation of irritating odors.

[0034] The optimal value is that the total ventilation volume of the first ventilation hole 32 on the premixed oil device 3 is 19:1 with the total ventilation volume of the second ventilation hole 33 and the third ventilation hole 34. A ratio greater than 19:1 and less than 19:1 can also achieve similar effects, and both are within the protection scope of this technical solution.

[0035] The wind shield 31 on the wind oil premixing device 3 is provided with a first ventilation hole 32, and the wind shield 31 is connected to the inner wall of the wind concentrator 1. The purpose is to control the ventilation volume. This solution is only one technical solution. The purpose of controlling the ventilation volume can also be achieved by increasing the distance between the wind shield 31 and the inner wall of the wind concentrator 1. Both are within the protection scope of this technical solution.

[0036] The ignition needle 4 is placed in the space formed by the premixing device 3 and the concentrating oil plate 5, which avoids carbon buildup and short circuits in the ignition needle 4 caused by dripping oil and splashing water when cooking or cleaning the fuel stove. The ignition needle 4 is a double-sided ignition design, with two ignition needles 4 placed on the left and right sides of the fuel injector 22 respectively. The ignition needle 4 can ignite the fuel sprayed from the fuel injector 22 from both sides, which can make the fuel fully ignited and improve the combustion efficiency of the fuel.

[0037] The purpose of the simultaneous ignition design of the ignition needle 4 on both sides of the fuel injector 22 is to ensure that the fuel injected by the fuel injector 22 can be fully ignited. The technical solution is multi-point ignition. The design of the dual ignition needle 4 is the best technical solution based on the combination of cost and effect. The design of multiple ignition needles 4, such as 3, 4, 5, 6, etc., can also achieve similar or better effects, and all of them are within the protection scope of this technical solution.

[0038] The flame-gathering port 51 on the flame-gathering oil plate 5 is a trapezoidal structure that gradually narrows upwards, which can accelerate the fusion and combustion of air and fuel oil from bottom to top, while gradually increasing the pressure of fuel oil from bottom to top.

[0039] The diversion groove 52 on the fire-gathering oil plate 5 is an inclined groove, which is set on the outside of the fire-gathering port 51. All the diversion grooves 52 are inclined to the same side and are evenly distributed around the outside of the fire-gathering port 51. This avoids the burning fuel from directly burning the fire-gathering oil plate 5 when it is sprayed out through the diversion groove 52, which would cause heat waste and reduce the service life of the fire-gathering oil plate 5.

[0040] The air vents 53 on the fire-gathering oil pan 5 connect the internal space of the air-gathering bowl 1 and the upper space of the fire-gathering oil pan 5. The air vents 53 are evenly distributed around the inner wall of the fire-gathering oil pan 5 to assist oxygenation and correct the direction of combustion of the fuel entering the fire-gathering oil pan 5.

[0041] The corrective ring 61 on the burner cap 6 is located at the center of the burner cap 6, directly opposite the ignition port 51. The inner diameter of the corrective ring 61 is larger than the outer diameter of the upper end of the ignition port 51. Under the action of the corrective ring 61, the burning fuel can pass through the gap between the ignition port 51 and the corrective ring 61 with a stable pressure, and enter the space formed by the outer wall of the ignition port 51 and the inner wall of the burner cap 6 in a spray manner, thereby accelerating the vaporization and combustion of the fuel.

[0042] The burner 62 on the burner cap 6 is set on the side wall of the burner cap 6. The burner 62 is evenly distributed around the side wall of the burner cap 6. The burner 62 is inclined towards the cross-section of the side wall of the burner cap 6, and the inclination direction is consistent with the inclination direction of the diversion groove 52. The burning fuel passes through the burner 62 and the diversion groove 52 and is sprayed out, forming a double-layer flame in the fire-gathering oil plate 5, so that the burning fuel can fully contact the air, further accelerating the vaporization and combustion speed.

[0043] In practice Fuel enters the fuel injection device 2 through the fuel inlet pipe 21 and is sprayed out from the fuel injector 22. It is ignited simultaneously by the ignition needle 4 from both sides. At the same time, air enters from the air inlet channel 11, passes through the air inlet 12, and rotates into the space between the air concentrator 1 and the air-fuel premixing device 3, causing the pressure in this space to increase rapidly. Then, part of the air passes through the second ventilation hole 33 and enters the air-fuel premixing device 3, causing the pressure in the air-fuel premixing device 3 to rise steadily, providing oxygen and upward assistance to the fuel sprayed from the fuel injector 22. Part of the air passes through the first... Ventilation vent 32 enters the space above the wind shield 31, and then passes through the third ventilation vent 34 into the premixing device 3. This provides oxygen to the fuel sprayed from the injector 22 and concentrates the fuel towards the center, preventing it from escaping and causing dripping or sticking inside the burner core. The fuel, premixed and ignited in the premixing device 3, rises into the concentrator 51. The concentrator 51 gradually narrows from bottom to top, causing the fuel entering the concentrator 51 to gradually increase in pressure. The fuel is ejected and then blocked by the burner cap 6 and the straightening ring 61, causing some of the burning fuel to be reflected down and convection with the fuel at the nozzle. This further disperses, vaporizes, and burns the fuel. The partially burned fuel passes through the gap between the straightening ring 61 and the nozzle and is injected into the space formed by the outer wall of the concentrator 51 and the inner wall of the burner cap 6 to continue burning and continuously heating the burner cap 6. Then, the burning fuel passes through the guide groove 52 and the flame hole 62 and is ejected in a rotating manner, forming a space between the concentrator oil plate 5 and the side wall of the burner cap 6. The combustion continues within the chamber, and the fuel sprayed out through the diversion channel 52 and the flame hole 62 forms a double-layer flame. The combustion of the double-layer flame increases the contact area between the fuel and the air, resulting in more complete combustion. At the same time, the air in the concentrator bowl 1 passes through the air hole 53 and enters the space formed by the side wall of the concentrator oil plate 5 and the flame suppressor 6, which applies upward pressure to the burning fuel and assists in oxygenation. This also reduces direct burning of the side wall of the concentrator oil plate 5, improves the thermal energy utilization rate, increases the service life of the concentrator oil plate 5, and reduces the cost of use and maintenance.

[0044] When this new type of energy-saving fuel stove core is working, the ignited fuel is quickly dispersed, pressurized, oxygenated, and vaporized inside the core. At the same time, by continuously heating the components inside the fuel stove core, the fuel is kept in a high-temperature environment, thereby achieving the effects of rapid fuel vaporization and efficient combustion.

[0045] Obviously, the above are only some embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various combinations and modifications of the aforementioned technical features. Any improvements, modifications, equivalent substitutions, or applications of the structure or method of the present utility model to other fields to achieve the same effect without departing from the concept and scope of the present utility model shall fall within the protection scope of the present utility model.
