Description

Technical Field

[0001] This utility model relates to the field of cooking equipment technology, and in particular to a civilian alcohol-based liquid fuel gas atomizing nozzle and stove. Background Technology

[0002] Alcohol-based fuel oil is a new scientific and technological achievement in my country. It is a flammable liquid produced by fertilizer plants that produce nitrogen and ammonia through a state-mandated methanol-blending equipment.

[0003] Environmentally friendly bio-ethanol oil is pressureless, non-explosive, non-toxic, and has an auto-ignition point of 385℃, making it safe and reliable to use. Even if it leaks and catches fire due to improper use, it can be extinguished with water, unlike diesel or liquefied petroleum gas (LPG) fires which can cause significant damage. Furthermore, accidentally leaked environmentally friendly oil is water-soluble or dries naturally, unlike diesel or LPG which pollute the environment or pose safety hazards. Environmentally friendly bio-ethanol oil is a renewable energy source. A national technology utilizes surplus electricity to generate easily stored methanol liquid by adding CO2 and hydrogen. The main component of this alcohol-based fuel is methanol. It is smokeless, odorless, pollution-free, residue-free, and leaves no black residue on pots, making it clean and hygienic. The carbon monoxide produced during combustion is lower than that of diesel and LPG, which is beneficial to the health of kitchen staff and the cleanliness of the kitchen environment.

[0004] The fuel injectors on currently used stoves are prone to clogging when using household alcohol-based liquid fuels, making cleaning very troublesome. Replacing them without cleaning requires replacing the entire unit, increasing the cost of stove operation. In addition, the fuel injectors currently used have poor atomization effect when atomizing household alcohol-based liquid fuels, resulting in uneven fuel spraying and poor flame stability. When the flame is on high, the large amount of fuel spraying does not significantly affect flame stability, but when the flame is on low, the amount of fuel spraying is very unstable, causing the flame to fluctuate, which greatly affects cooking.

[0005] To address the aforementioned issues, this utility model document proposes a civilian alcohol-based liquid fuel gas atomization injector. Utility Model Content

[0006] This utility model provides a civilian alcohol-based liquid fuel atomization nozzle that is not easily clogged, easy to clean, and improves the atomization and spraying stability of the civilian alcohol-based liquid fuel, thereby enhancing the flame stability of the stove when the flame is low.

[0007] This utility model provides the following technical solution:

[0008] A civilian alcohol-based liquid fuel gas atomizing nozzle includes a main body, which comprises a sleeve and a mounting block. One end of the sleeve is fixedly connected to the mounting block, and a positioning block is provided inside the sleeve. The positioning block has a locking hole and a first air passage. The other end is threadedly connected to a nozzle. A mandrel is provided inside the sleeve, and a first air chamber is formed between the mandrel and the sleeve. One end of the mandrel is locked in the locking hole, and the other end is located inside the nozzle. A second air chamber communicating with the first air chamber is left between the mandrel and the inner wall of the nozzle. An oil passage is provided inside the mandrel along its length. The side wall of the mounting block has an oil pipe connection hole and an air pipe connection hole. The inside has an oil delivery hole connecting the oil passage and the oil pipe connection hole, as well as a second air passage communicating with the first air passage. The air pipe connection hole is connected to the first air chamber through the first air passage and the second air passage.

[0009] Furthermore, the top edge of the mandrel is a first inclined surface, and the inner wall of the nozzle is a second inclined surface. The inclination angle of the first inclined surface is the same as that of the second inclined surface, and the first inclined surface and the second inclined surface abut against each other. An air groove is opened around the periphery of the top end face of the mandrel, and the depth of the end of the air groove near the side wall of the mandrel is greater than the height of the first inclined surface.

[0010] Furthermore, there are multiple air grooves, which are evenly distributed around the periphery of the top surface of the mandrel.

[0011] Furthermore, the air groove is a depth-gradient groove, with the depth at the end near the center being less than the depth at the end near the sidewall.

[0012] Furthermore, a positioning block is sleeved on the middle side wall of the mandrel, the positioning block abuts against the inner side wall of the sleeve, and the positioning block has a third air passage for gas to pass through along its height direction.

[0013] Furthermore, the bottom of the mounting block is also provided with threaded mounting holes.

[0014] Furthermore, the outer wall of the sleeve is threaded with a mounting nut, and the width of the mounting block is greater than the diameter of the sleeve.

[0015] A stove equipped with a civilian alcohol-based liquid fuel gas atomizing nozzle as described in any one of claims 1-7.

[0016] In this invention, the alcohol-based liquid fuel enters the oil supply port through the oil pipe connection hole and reaches the oil circuit, while the gas enters through the gas pipe connection hole, passes through the first and second gas passages, enters the first gas chamber, and reaches the second gas chamber. It is then rapidly sprayed out from the nozzle. At the same time as it is sprayed out from the nozzle, a low pressure is formed at the oil circuit at the top of the spindle, causing the alcohol-based liquid fuel to flow out from the oil circuit and mix with the gas. The high-speed flow of the gas achieves an atomization effect, and it is then sprayed out from the nozzle for combustion. The flow rate of the alcohol-based liquid fuel from the oil circuit is stable, ensuring the stability of the atomized alcohol-based liquid fuel sprayed from the nozzle, thereby ensuring the stability of the flame. The nozzle, main body, and spindle are all detachable, making it easy to clean or replace, avoiding nozzle clogging, and reducing replacement costs. Attached Figure Description

[0027] Example 1:

[0028] Reference Figure 1 , Figure 2 and Figure 3As shown, a civilian alcohol-based liquid fuel atomizing nozzle includes a main body, which comprises a sleeve 1 and a mounting block 2. One end of the sleeve 1 is fixedly connected to the mounting block 2, and a positioning block 7 is provided inside the sleeve 1. The positioning block 7 has a locking hole 701 and a first air passage 702. The other end is threadedly connected to a nozzle 3. A mandrel 4 is provided inside the sleeve 1, forming a first air chamber 8 between the mandrel 4 and the sleeve 1. One end of the mandrel 4 is locked in the locking hole 701, and the other end is located inside the nozzle 3. Furthermore, a second air chamber 9, which is connected to the first air chamber 8, is left between the nozzle 3 and the inner wall. An oil passage 401 is provided inside the spindle 4 along its length. The side wall of the mounting block 2 is provided with an oil pipe connection hole 202 and an air pipe connection hole 201. Inside, there is an oil delivery hole 203 that connects the oil passage 401 and the oil pipe connection hole 202, as well as a second air passage 205 that is connected to the first air passage 702. The air pipe connection hole 201 is connected to the first air chamber 8 through the first air passage 702 and the second air passage 205.

[0029] The mandrel 4 is fixed inside the sleeve 1 via the clamping hole 701. The oil pipe connection hole 202 is connected to the external oil supply pipe, and the air pipe connection hole 201 is connected to the external air pipe. Airflow enters the mounting block 2 through the external air pipe, and then enters the first air chamber 8 through the first air passage 702 and the second air passage 205. The first air chamber 8 is connected to the second air chamber 9, allowing the gas to enter the second air chamber 9 and be sprayed out through the nozzle 3. The alcohol-based liquid fuel enters the oil supply hole 203 through the external oil supply pipe and then reaches the oil passage 401 inside the mandrel 4. As the gas is ejected from the nozzle 3, an airflow is formed at the top of the spindle 4, which reduces the pressure at the top of the spindle 4. Due to the low pressure, the alcohol-based liquid fuel inside the oil circuit 401 will generate a siphon effect, causing the alcohol-based liquid fuel to flow out from the top of the spindle 4. The outflowing alcohol-based liquid fuel comes into contact with the ejected airflow, and under the action of the airflow, the alcohol-based liquid fuel will produce an atomization effect and be ejected from the nozzle 3 along with the airflow. Even when the stove is on low flame, the airflow still carries the alcohol-based liquid fuel to flow out steadily, ensuring the stability of the flame.

[0030] The nozzle 3 is threadedly connected to the sleeve 1. The nozzle 3 can be disassembled, and the internal spindle 4 can be removed after the nozzle 3 is disassembled, which is convenient for cleaning or replacement, reduces the cost of using the stove, and avoids the stove from being blocked, which affects the normal use of the stove.

[0031] The top edge of the mandrel 4 is a first inclined surface 403, and the inner wall of the nozzle 3 is a second inclined surface 301. The inclination angle of the first inclined surface 403 is the same as that of the second inclined surface 301, and the first inclined surface 403 and the second inclined surface 301 abut against each other. An air groove 402 is opened around the top end face of the mandrel 4, and the depth of the end of the air groove 402 near the side wall of the mandrel 4 is greater than the height of the first inclined surface 403.

[0032] The first inclined surface 403 of the mandrel 4 abuts against the second inclined surface 301 inside the nozzle 3. On the one hand, the nozzle 3 fixes the mandrel 4 and presses it tightly onto the positioning block 7. On the other hand, the gas enters the second chamber and enters from the side of the gas groove 402. It is then ejected from the top of the gas groove 402, forming an upward jet of air above the mandrel 4. When the air is ejected from the top surface of the mandrel 4, the air pressure on the top surface of the mandrel 4 decreases, creating a siphon effect. This causes the alcohol-based liquid fuel in the oil passage 401 inside the mandrel 4 to flow in the negative pressure direction and then flow out from the top of the mandrel 4. The outflowing alcohol-based liquid fuel comes into contact with the upward jet of air and is atomized under the impact of the airflow.

[0033] The depth of the air groove 402 is greater than the height of the first inclined surface 403, ensuring that the airflow can enter from the side of the air groove 402, and preventing the first inclined surface 403 from abutting against the second inclined surface 301 and sealing the side of the air groove 402, thus affecting the flow of gas.

[0034] There are multiple air grooves 402, which are evenly distributed around the top surface of the mandrel 4.

[0035] Multiple evenly distributed air grooves 402 stabilize the airflow formed at the top of the spindle 4 and make the air pressure at the top of the spindle 4 uniform, avoiding uneven air pressure from affecting the flow of alcohol-based liquid fuel and thus affecting the stability of the stove flame.

[0036] The air groove 402 is a depth-gradient groove, with the depth at the end near the center being less than the depth at the end near the side wall.

[0037] When gas enters the gas groove 402 from the side, the gas flows upward because the bottom surface of the gas groove 402 is inclined. If the bottom surface were flat, the gas would directly impact the other side of the gas groove 402, which would affect the subsequent gas flow. Although the gas will eventually be discharged from the top of the gas groove 402, generating an upward airflow, it will lose some kinetic energy, reducing the flow speed and making the flow speed unstable. This would cause the air pressure on the top surface of the mandrel 4 to fluctuate, resulting in an unstable outflow speed of the alcohol-based liquid fuel, which would affect the stability of the flame. Therefore, the inclined bottom surface of the gas groove 402 can ensure the gas flow speed, thereby ensuring the stability of the flame.

[0038] A positioning block 6 is fitted on the middle side wall of the mandrel 4. The positioning block 6 abuts against the inner side wall of the sleeve 1, and the positioning block 6 has a third air passage 601 for gas to pass through along its height direction.

[0039] The positioning block 6 abuts against the side wall of the sleeve 1, improving the stability of the mandrel 4 installation, while the third air passage 601 facilitates the passage of gas to the second air chamber 9.

[0040] The bottom of mounting block 2 is also provided with threaded mounting holes 204.

[0041] The mounting block 2 can be easily fixed to the stove by using bolts to fit the threaded mounting holes 204.

[0042] The outer wall of the sleeve 1 is threaded with a mounting nut 5, and the width of the mounting block 2 is greater than the diameter of the sleeve 1.

[0043] The sleeve 1 is installed on the stove by installing nut 5. The sleeve 1 is passed through the mounting plate on the stove and then the installation nut 5 is tightened. The width of the mounting block 2 is greater than the diameter of the sleeve 1, so that the installation nut 5 and the top surface of the mounting block 2 cooperate to clamp the mounting plate on the stove, thereby completing the positioning of the sleeve 1.

[0044] In use, the mounting block 2 of the atomizing nozzle is fixed to the stove via the threaded mounting hole 204 and bolts. The sleeve passes through the stove mounting plate and is then tightened with the mounting nut 5. The mounting nut 5, in conjunction with the mounting block 2, secures the sleeve, thus fixing the atomizing nozzle to the stove. The oil pipe connection hole 202 connects to the external oil supply pipe, and the gas pipe connection hole 201 connects to the external gas pipe. Airflow enters the mounting block 2 through the external gas pipe, then enters the first gas chamber 8 through the first gas passage 702 and the second gas passage 205, and after passing through the third gas passage 601, enters the second gas chamber 9. Finally, it enters the gas groove 402 from the side, where it is refracted upwards by the bottom surface of the gas groove 402, causing the airflow to... The gas is ejected from the top of the slot 402, creating an upward airflow on the top surface of the spindle 4, which then exits from the nozzle 3. The rising airflow reduces the air pressure on the top surface of the spindle 4. The alcohol-based liquid fuel enters the oil inlet 203 from the external oil pipe and then reaches the oil passage 401 inside the spindle 4. Due to the low pressure at the top of the oil passage 401, the alcohol-based liquid fuel inside the oil passage 401 creates a siphon effect, causing the alcohol-based liquid fuel to flow out from the top of the spindle 4. The outflowing alcohol-based liquid fuel comes into contact with the ejected airflow, and under the action of the airflow, the alcohol-based liquid fuel is atomized and ejected from the nozzle 3 along with the airflow. Even when the stove is on low flame, the airflow still carries the alcohol-based liquid fuel out steadily, ensuring the stability of the flame.

[0045] In practical use, the sleeve 1, mounting block 2, and positioning block 7 are integrally formed, which facilitates processing and improves the overall structural strength of the fuel injector, ensuring the sealing performance of the fuel injector. The positioning block 6 and the spindle 4 are integrally formed, which facilitates production and manufacturing.

[0046] The oil pipe connection hole 202 is internally threaded to connect to the oil nozzle screw, and the air pipe connection hole 201 is internally threaded to connect to the air nozzle screw, so as to facilitate connection to the external oil pipe and air pipe respectively.

[0047] The angle between the gas slot 402 and the tangent at the side opening of the gas slot 402 is 30°-60°. This allows the gas ejected from multiple gas slots 402 to generate a spiral upward airflow, further improving the stability of the airflow and thus further improving the stability of the flame.

[0049] A stove is equipped with a civilian-grade alcohol-based liquid fuel gas atomizing nozzle, which improves the stability of the stove flame combustion.
