Description

Technical Field

[0001] This utility model discloses a fuel stove core that improves combustion efficiency, and 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 complete combustion of alcohol-based fuel, it is necessary to fully vaporize the fuel through high-temperature or high-pressure injection, and then mix it thoroughly with air for combustion. In existing technologies, alcohol-based fuel can be heated to its boiling point by electric heating to turn it into a gas before combustion, thus achieving complete combustion. However, this type of equipment requires the use of electric heating elements for preheating, which is costly and inconvenient to use. Some equipment also has multiple components that cannot fully vaporize the fuel, resulting in incomplete combustion. Utility Model Content

[0003] The main technical problem solved by this utility model is to provide a fuel stove core that improves combustion efficiency. When the ignited fuel passes through the three-chamber vaporization cap of the fuel stove core, the burning fuel is pressurized multiple times, sprayed and dispersed, and continuously heated by the three-chamber vaporization cap, so that the fuel is fully vaporized and burned, thereby improving the combustion efficiency of the fuel stove core and achieving energy saving.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a fuel stove core for improving combustion efficiency, comprising: a concentrator bowl, a vaporization plate, and a three-chamber vaporization cap. The concentrator bowl has an opening at the top, and the vaporization plate is placed on the concentrator bowl, forming a relatively enclosed space between the concentrator bowl and the vaporization plate. The three-chamber vaporization cap is placed on the vaporization plate, forming a first vaporization combustion chamber, a second vaporization combustion chamber, and a third vaporization combustion chamber between the vaporization plate and the three-chamber vaporization cap. The space of the three vaporization combustion chambers gradually increases from the inner layer to the outer layer, avoiding excessive pressure in the combustion chambers and preventing smoldering, thus reducing the combustion rate of fuel.

[0005] Preferably, the air-collecting bowl is provided with a stagnation groove, an oil return hole, an air inlet channel, and an air inlet. It is also equipped with a fuel injector, an ignition needle, a stabilizer plate, and an oil inlet pipe. The stagnation groove is a trapezoidal groove with a wider top and a narrower bottom, located at the bottom of the air-collecting bowl. The oil return hole is located at the bottom of the stagnation groove and extends through the bottom of the air-collecting bowl, connecting to the oil reservoir. The air inlet channel is located at the bottom of the air-collecting bowl. The fuel injector is threadedly installed at the center of the bottom of the air-collecting bowl. The air inlet is located at the bottom of the air-collecting bowl, evenly distributed around the fuel injector, and directly opposite the air inlet channel. The ignition needle passes through the air-collecting bowl and extends above the fuel injector. The stabilizer plate is an inverted disc-shaped structure, fixed to the fuel injector by threads, so that the stabilizer plate covers the air inlet, and the outer edge of the stabilizer plate is directly opposite the stagnation groove. The oil inlet pipe passes through the air inlet channel and is threadedly installed and fixed below the fuel injector.

[0006] Preferably, the vaporizing disc is provided with a pressure stabilizing wall, an inlet, a guide ring, fixing teeth, and an air hole. The pressure stabilizing wall is placed inside the air concentrator bowl, and the nozzle of the fuel injector is placed inside the pressure stabilizing wall to prevent the fuel sprayed from the fuel injector from escaping in the air concentrator bowl. The inlet gradually narrows from bottom to top to facilitate the collection of the fuel sprayed from the fuel injector and ignited. The guide ring is a protrusion on the outer edge of the outer step of the inlet, and the guide ring is inclined upward from the inside to the outside. The fixing teeth are three protrusions at the bottom of the vaporizing disc, which are evenly distributed along the outer side of the guide ring. The air hole penetrates the vaporizing disc and is evenly distributed around the inner wall of the vaporizing disc.

[0007] Preferably, the three-chamber vaporization cap is an inverted bowl-shaped structure. The three-chamber vaporization cap is provided with a first vaporization wall and a second vaporization wall. The first vaporization wall is connected to the step on the outside of the fire inlet and is placed inside the guide ring. The second vaporization wall is connected to the air-oil vaporization plate and is fixed by fixing teeth.

[0008] Preferably, the air stabilizing disc can be adjusted up and down on the fuel injector by rotation, thereby increasing or decreasing the airflow volume of the air nozzle as needed.

[0009] Preferably, the ventilation area of ​​the burner inlet is 1.5 to 2.5 times the total ventilation area of ​​the air vent. In a more preferred embodiment, the ventilation area of ​​the burner inlet is twice the total ventilation area of ​​the air vent. If the ratio of the ventilation area of ​​the burner inlet to the total ventilation area of ​​the air vent is too large or too small, it will reduce the fuel efficiency of the burner core.

[0010] Preferably, the first vaporization wall is provided with two rings of combustion holes, namely a first combustion hole and a second combustion hole, which are evenly and alternately distributed around the first vaporization wall, and the diameter of the first combustion hole is larger than the diameter of the second combustion hole.

[0011] Preferably, the second vaporization wall is provided with two rings of flame outlet holes, namely a first flame outlet hole and a second flame outlet hole. The first flame outlet hole and the second flame outlet hole are evenly and alternately distributed around the second vaporization wall, and the diameter of the first flame outlet hole is larger than the diameter of the second flame outlet hole.

[0012] Preferably, the number of the first combustion holes is 12.

[0013] Preferably, the number of the first flaming holes is the same as the number of the first combustion holes, and the diameter of the first flaming holes is larger than the diameter of the first combustion holes.

[0014] Preferably, the number of the second combustion holes is 12.

[0015] Preferably, the number of the second flame outlet holes is twice the number of the second combustion holes, and the diameter of the second flame outlet holes is larger than the diameter of the second combustion holes.

[0016] In practice

[0017] Fuel enters the fuel injector through the fuel inlet pipe and is sprayed out, where it is ignited by the ignition needle. Simultaneously, air flows through the air intake channel and into the air collector bowl. The upward airflow is blocked and guided by the air stabilizing plate, flowing around the plate to prevent it from blowing directly upwards into the air collector bowl, which would cause instability. The upward airflow in the air collector bowl provides oxygen and pressurizes the ignited fuel. The burning fuel is then dispersed by the three-chamber vaporization cap and enters the first vaporization combustion chamber, simultaneously heating the three-chamber vaporization cap and the first vaporization wall. Because the diameter of the ignition port is larger than the combined diameter of the first and second combustion holes, and the space in the first vaporization combustion chamber gradually decreases from top to bottom, the pressure inside the first vaporization combustion chamber gradually increases from top to bottom. This causes some of the burning fuel in the first vaporization combustion chamber to pass through the second combustion hole in a spray pattern. The fuel enters the second vaporization combustion chamber and, under the action of the guide ring, is sprayed onto the second vaporization wall between the first and second flame outlets, where it is dispersed and vaporized. Simultaneously, the second vaporization wall is heated. Another portion of the burning fuel passes through the first combustion hole and is injected into the second vaporization combustion chamber. The burning fuel entering the second vaporization chamber is blocked by the second vaporization wall, causing it to be heated and pressurized, further vaporizing and burning. Then, the burning fuel in the second vaporization combustion chamber is sprayed out from the first and second flame outlets and enters the third vaporization combustion chamber, where it is sprayed onto the inner wall of the vaporization disc, where it is dispersed and vaporized again. Simultaneously, the air sprayed from the air nozzle further disperses and oxygenates the burning fuel entering the third vaporization combustion chamber, ensuring complete combustion and correcting the upward flame direction within the third vaporization combustion chamber.

[0018] During this period, the burning fuel continuously heats the vaporization disc and the three-chamber vaporization cap, keeping the three-chamber vaporization cap at a high temperature. With the proportional coordination of the size, distribution, and number of the inlet, the first vaporization combustion chamber, the second vaporization combustion chamber, the third vaporization combustion chamber, the first combustion hole, the second combustion hole, the first outlet hole, and the second outlet hole, the three-chamber vaporization cap can be maintained between 600 degrees Celsius and 800 degrees Celsius. This allows the fuel to vaporize quickly and fully as it passes through the three-chamber vaporization cap, and to fully assist oxygenation and combustion in the third vaporization combustion chamber, thereby improving the combustion efficiency of the fuel stove core.

[0019] During this period, when the ignition is started, because the temperature inside the fuel stove is low, some alcohol oil will drip onto the air stabilizing plate and then slide into the retention groove, pass through the oil return hole, and re-enter the oil storage tank for reuse.

For those skilled in the art to which this application pertains, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0025] The beneficial effects of adopting the above technical solution are as follows: The fuel stove core with improved combustion efficiency is designed with a three-chamber vaporization cap and an oil vaporization disc, which allows the fuel to be pressurized and sprayed multiple times during combustion, and continuously heats the three-chamber vaporization cap, keeping it in a high-temperature and constant-temperature state. This achieves the effect of continuous vaporization of the fuel entering the three-chamber vaporization cap, ensuring complete combustion and improving the combustion efficiency and energy saving of the fuel stove core. The fuel stove core with improved combustion efficiency uses high-pressure injection and self-heating to pressurize and heat the alcohol-based fuel, enabling it to vaporize quickly and completely, greatly shortening the vaporization process and time, and reducing combustion costs. During combustion, the heat energy of the fuel stove core with improved combustion efficiency is concentrated in the central part, without burning and heating the outer shell, avoiding heat loss and waste, and improving the utilization rate of heat energy.

[0046] In practice

[0047] Fuel enters the fuel injector 11 through the fuel inlet pipe 14 and is sprayed out from the fuel injector 11, where it is ignited by the ignition needle 12. Simultaneously, air flows through the air intake channel and into the air collector bowl 1 through the air intake port 104. The upward airflow is blocked and guided by the air stabilizing plate 13, flowing around the air stabilizing plate 13 to prevent the airflow entering the air collector bowl 1 from blowing directly upwards, thus preventing instability in the airflow direction within the air collector bowl 1. The upward airflow within the air collector bowl 1 provides oxygen and pressurizes the ignited fuel. The burning fuel is then dispersed upwards by the three-chamber vaporizer cap 3 and enters the... The first vaporization combustion chamber 33 simultaneously heats the three-chamber vaporization cap 3 and the first vaporization wall 31. Since the diameter of the inlet 22 is larger than the combined diameter of the first combustion hole 36 and the second combustion hole 37, and the space in the first vaporization combustion chamber 33 gradually decreases from top to bottom, the pressure inside the first vaporization combustion chamber 33 gradually increases from top to bottom after the burning fuel flows into it. This causes a portion of the burning fuel in the first vaporization combustion chamber 33 to pass through the second combustion hole 37 and be sprayed out. The fuel enters the second vaporization combustion chamber 34 in a jet-like manner and, under the action of the guide ring 23, is sprayed onto the second vaporization wall 32 between the first and second flame outlets 38 and 39, where it is dispersed and vaporized. Simultaneously, the second vaporization wall 32 is heated. Another portion of the burning fuel is injected into the second vaporization combustion chamber 34 through the first combustion hole 36. The burning fuel entering the second vaporization chamber is blocked by the second vaporization wall 32, causing the burning fuel to be heated and pressurized within the second vaporization combustion chamber 34, further vaporizing and burning. Then, the burning fuel in the second vaporization combustion chamber 34 is sprayed out from the first and second flame outlets 38 and 39, entering the third vaporization combustion chamber 35 and sprayed onto the inner wall of the air-fuel vaporization disc 2, where it is dispersed and vaporized again. Simultaneously, the air sprayed from the air outlet 25 further disperses and oxygenates the burning fuel entering the third vaporization combustion chamber 35, ensuring complete combustion of the fuel within the third vaporization combustion chamber 35 and correcting the upward combustion of the flame within the third vaporization combustion chamber 35.

[0048] During this period, the burning fuel continuously heats the vaporization disc 2 and the three-chamber vaporization cap 3, keeping the three-chamber vaporization cap 3 at a high temperature. With the proportional coordination of the size, distribution, and number of the inlet 22, the first vaporization combustion chamber 33, the second vaporization combustion chamber 34, the third vaporization combustion chamber 35, the first combustion hole 36, the second combustion hole 37, the first outlet hole 38, and the second outlet hole 39, the three-chamber vaporization cap 3 can be maintained between 600 degrees Celsius and 800 degrees Celsius. This allows the fuel to vaporize quickly and fully as it passes through the three-chamber vaporization cap 3, and to fully assist oxygenation and combustion in the third vaporization combustion chamber 35, thereby improving the combustion efficiency of the fuel stove core.

[0049] During this period, when the ignition is started, due to the low temperature inside the fuel stove, some alcohol oil will drip onto the stabilizing plate 13 and then slide into the retention groove 101, pass through the return oil hole 102, and re-enter the oil storage tank for reuse.

[0050] 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.
