Description

Technical Field

[0001] This utility model relates to the technical field of liquid fuel gasification mechanisms, and more specifically, to a preheated liquid fuel gasification module. Background Technology

[0002] Stoves and burners are essential heating tools for homes, restaurants, hot pot restaurants, and outdoor work, with the vaporizer being the core component of liquid fuel stoves and burners. Currently, due to the scarcity of oil resources, liquefied petroleum gas (LPG) refined from petroleum is in short supply. Furthermore, the massive investment and long construction period for natural gas pipelines have resulted in insufficient market supply and a severe shortage. Diesel and kerosene, due to their high prices, lack promotional value and are heavily polluting, have been banned for use in the catering and industrial sectors. To avoid being constrained by oil resources, countries have increased their efforts to develop alternative energy sources. Methanol and ethanol, as renewable energy sources, have received attention from various countries, leading to increased efforts in the development and utilization of methanol- and ethanol-based liquid fuels. Furthermore, the large-scale promotion of methanol-based alcohol-based liquid fuels, as a clean energy source, can change the current situation of severe environmental pollution caused by LPG, natural gas, diesel, and kerosene. Therefore, cleaner liquid fuels such as alcohol-based liquid fuels are increasingly favored by users.

[0003] Because liquid fuels generally have a low boiling point and are easily volatile, and are more likely to be highly uniformly mixed with air after gasification, allowing fuel and oxygen to fully participate in the reaction according to stoichiometric ratio, reducing local oil-rich or oil-poor phenomena, and improving combustion efficiency, liquid fuel gasification furnaces are commonly used in the market to burn liquid fuels.

[0004] A typical combustion device with liquid fuel gasification function, as shown in patent document CN201811315340.8 entitled "A Liquid Fuel Gasification Burner Head", includes a lower burner head cover, a middle burner head cover, and an upper burner head cover. The bottom of the lower burner head cover has an installation port, on which a gas supply adapter is fixedly installed. The middle burner head cover has two parallel annular slots along its circumference. The bottom of the upper burner head cover has a gasification chamber, and the bottom sides of the gasification chamber have insertion protrusions that match the slots. A heating element is fixedly installed at the bottom of the upper burner head cover and outside the gasification chamber. A liquid inlet and a gas outlet are fixedly installed on the outside of the upper burner head cover. The gas outlet is connected to the gas inlet end of the gas supply adapter. A nozzle is threadedly connected to the gas outlet end of the gas supply adapter. An ignition needle is provided at the nozzle nozzle position. A thermostat is fixedly installed outside the gasification chamber and on one side of the gas outlet. The output end of the thermostat is connected to the heating element through a wire.

[0005] However, the gasification chamber layout of the above-mentioned device is relatively narrow, and impurities in the liquid fuel that cannot be gasified are easily blocked in the gasification chamber. The gas supply pipeline is also relatively complex, which cannot guarantee that the liquid fuel can be stably and fully gasified and then output. There is a lot of room for improvement. Utility Model Content

[0006] To address the problems of unreasonable gasification chamber design in current liquid fuel gasification devices on the market, which easily leads to impurities clogging the gasification chamber and a complex and circuitous gas supply path, making it impossible to guarantee the smooth output of gasified liquid fuel, a preheated liquid fuel gasification module is provided.

[0007] The preheated liquid fuel gasification module includes a gasification chamber with a liquid inlet and a drain outlet connected to its side. A heating plate is installed at the bottom, and multiple air outlets are installed at the top. A fuel pump is connected to the liquid inlet, and a temperature control switch is attached to the bottom of the heating plate. The temperature control switch is electrically connected to the heating plate and the fuel pump.

[0008] Furthermore, the drain outlet is located on the opposite side of the liquid inlet, and the height of the drain outlet is less than that of the liquid inlet.

[0009] Furthermore, the heating plate is covered with multiple upward-facing heat-conducting compartments, which are arranged in a honeycomb pattern.

[0010] Furthermore, the heating plate and the heat-conducting compartment are integrally formed, and the upper side of the heating plate and the heat-conducting compartment are sealed in the vaporization chamber. A heating wire is installed on the lower side of the heating plate, and the heating wire is electrically connected to a temperature control switch.

[0011] Furthermore, the heating wire is spirally arranged in a mosquito coil shape and covers the lower side of the heating plate, with the heating wire bending back and forth from side to side.

[0012] Furthermore, a premixed gas pipe is connected to the gas outlet, an oxygen inlet is connected to the side of the premixed gas pipe, and a flame cap is connected to the top of the premixed gas pipe.

[0013] Furthermore, the air outlet protrudes upward from the vaporization chamber, the top of the air outlet is conical, and the bottom of the premixed gas pipe is threaded onto the air outlet.

[0014] Furthermore, the premixed gas pipe is provided with multiple oxygen inlets on its side, and each oxygen inlet is funnel-shaped from the outside to the inside.

[0015] Furthermore, the vaporization chamber, the gas outlet, and the premixed gas pipe are all wrapped with a flame-retardant and heat-conducting layer.

[0016] Furthermore, a horizontal support leg is connected to the lower part of the vaporization chamber.

[0017] The advantages of this utility model are:

[0018] 1. The design of the electric heating plate linked fuel pump ensures that the liquid fuel is completely vaporized before it is ignited at the burner head, and no unvaporized fuel is output.

[0019] 2. It is equipped with a drain outlet and a detachable premixed gas pipe for easy cleaning and maintenance.

[0020] 3. Simple structure and low manufacturing cost. Attached Figure Description

[0029] To address the problems of unreasonable gasification chamber design in current liquid fuel gasification devices on the market, which easily leads to impurities clogging the gasification chamber and a complex and circuitous gas supply path, making it impossible to guarantee the smooth output of gasified liquid fuel, a preheated liquid fuel gasification module is provided.

[0033] like Figures 1 to 5 As shown, this embodiment provides a preheated liquid fuel gasification module, including a gasification chamber 1. The side of the gasification chamber 1 is connected to a liquid inlet 101 and a drain outlet 102. An electric heating plate 2 is provided at the bottom, and multiple air outlets 3 are provided at the top. The liquid inlet 101 is connected to a fuel pump 4. A temperature control switch 5 is attached to the bottom of the electric heating plate 2 and is electrically connected to the electric heating plate 2 and the fuel pump 4.

[0034] When the equipment is in use, the fuel pump 4 is connected to the liquid fuel storage container, while the heating plate 2, fuel pump 4, and temperature control switch 5 can be uniformly controlled by a commonly available microcontroller module. After the power switch is turned on, the heating plate 2 begins to heat up. Once the temperature control switch 5 detects that the temperature of the heating plate 2 has reached the set value, the fuel pump 4 starts to input the liquid fuel into the vaporization chamber 1. The liquid fuel vaporizes upon contact with the high-temperature heating plate 2 and is output from the gas outlet 3 at the top of the vaporization chamber 1. An ignition electrode can be installed above the gas outlet 3 to facilitate immediate use of the vaporized liquid fuel and prevent it from cooling down and reverting to liquid.

[0035] The drain outlet 102 is located on the opposite side of the liquid inlet 101, and the height of the drain outlet 102 is less than that of the liquid inlet 101. The drain outlet 102, which is located opposite to the liquid inlet 101 and is lower than the liquid inlet 101, ensures that when the vaporization chamber 1 is poured, residual impurities at the bottom of the vaporization chamber 1 will not flow into the liquid inlet 101 and cause pollution.

[0036] The heating plate 2 is covered with multiple upward-facing heat-conducting compartments 201, which are arranged in a honeycomb pattern. The heat-conducting compartments 201 can significantly increase the contact area between the liquid fuel and the heating plate 2, thereby increasing the gasification rate.

[0037] The heating plate 2 and the heat-conducting compartment 201 are integrally formed. The upper side of the heating plate 2 and the heat-conducting compartment 201 are both sealed in the vaporization chamber 1. A heating wire 202 is installed on the lower side of the heating plate 2, and the heating wire 202 is electrically connected to the temperature control switch 5. The heating wire 202 is spirally arranged in a mosquito coil shape and covers the lower side of the heating plate 2, bending back and forth. The heating wire 202 is evenly laid on the bottom of the heating plate 2 and does not come into contact with the liquid fuel, which can ensure that the liquid fuel is heated evenly and has high safety.

[0038] The gas outlet 3 is connected to a premixed gas pipe 6, which has an oxygen inlet 601 connected to its side and a burner cap 602 connected to its top. Because the gasified fuel continuously flows upwards at high speed in the premixed gas pipe 6, air is rapidly drawn into the premixed gas pipe 6 through the oxygen inlet 601 under pressure, allowing the gasified fuel to mix quickly with oxygen, thus improving combustion efficiency. The burner cap 602 is a common component of the burner head and provides wind protection during fuel combustion.

[0039] The air outlet 3 protrudes upward from the vaporization chamber 1, and its top is conical. The bottom of the premixed air pipe 6 is threaded onto the air outlet 3. The threaded premixed air pipe 6 facilitates installation, disassembly, and maintenance, and allows for different output paths to be configured for the air outlet 3 as needed. The conical shape of the air outlet 3 facilitates connection to the premixed air pipe 6 and can increase the jet velocity.

[0040] The premixed gas pipe 6 has multiple oxygen inlets 601 arranged around its side, each of which is funnel-shaped from the outside in. The funnel shape can accelerate the air flow rate, while the multiple oxygen inlets 601 ensure that the gasified fuel can be fully mixed with the oxygen in the air.

[0041] The gasification chamber 1, the gas outlet 3, and the premixed gas pipe 6 are all wrapped with a flame-retardant and heat-conducting layer. In this embodiment, the gasification chamber 1, the gas outlet 3, and the premixed gas pipe 6 are all made of high-temperature resistant steel and other metal materials, which have high structural strength. After the gasified fuel is ignited, the residual heat of combustion can be conducted to the electric heating plate 2, and the electric heating wire 202 does not need to run continuously, making the equipment more energy-efficient.

[0042] A horizontal support leg 7 is connected to the lower part of the vaporization chamber 1. The horizontal support leg 7 can ensure that the equipment is installed and positioned correctly, and prevent the vaporization chamber 1 from tilting, which would cause the liquid fuel to not be able to contact the heating plate 2 evenly.

[0043] The above description is a further detailed explanation of the present utility model in conjunction with specific preferred embodiments. It should not be assumed that the specific implementation of the present utility model is limited to these descriptions. All equivalent changes and modifications made within the scope of this application should still fall within the scope of the present utility model.
