Description

Technical Field

[0001] This utility model relates to the field of stove heads, and in particular to a novel double-layer air intake device for stove heads. Background Technology

[0002] A stove is a common cooking device in the kitchen, mainly used to cook food by heating it. Depending on the heating method, stoves can be divided into gas stoves, electric stoves, and induction cookers. Gas stoves use natural gas or liquefied petroleum gas as energy, and heat food by burning it to produce an open flame. The heat is adjustable and suitable for various cooking methods. Electric stoves use electric heating elements, which have high stability and do not require gas, making them safer. Induction cookers use the principle of electromagnetic induction, which generates a magnetic field through current to directly heat the pot. They are highly efficient, have concentrated heat, and can quickly heat food.

[0003] Methanol, as a safe and clean liquid fuel, is gradually being widely used in commercial, household, and vehicle applications. The country has been conducting pilot programs for the commercial and vehicle applications of methanol-based fuels for more than a decade. Especially with the upcoming implementation of methanol-based fuel standards, the market prospects are broad. Compared with traditional gas, methanol fuel is safer, more environmentally friendly, and more energy-efficient, which helps reduce pollution and energy consumption and promotes green and sustainable development.

[0004] Current alcohol-based fuel application technologies mainly rely on pump pressure to deliver fuel to the product. However, current products are mainly divided into stoves with or without fans, which vaporize fuel through electric heating or combustion heat. In extremely cold weather or when the fuel has not vaporized, and most burners are not sealed, fuel can leak into the container or the bottom of the stove through air vents, ignition needles, and flameout protection needle fixing pipes, causing fuel leaks and accidents. At the same time, the air-fuel mixture ratio is still difficult to control, emissions are difficult to achieve ideal conditions, and energy consumption is relatively high. To address these issues, a new type of double-layer air intake device for burners is proposed. Utility Model Content

[0019] Working principle: Air is fed into the high-temperature vaporization chamber 18 through the intake pipe 3 and fuel through the fuel pipe 4, where they are mixed. The mixture then enters the low-temperature vaporization chamber 20 through the fuel outlet 22 for further mixing and vaporization. From the low-temperature vaporization chamber 20, fuel is transported through the U-shaped pipe 5 to the connector 9, where it is sprayed from the nozzle 11 and then to the igniter 16. The fuel is ignited through the ignition needle hole 14 in the ignition needle fixing pipe 6, thus igniting the fuel. The dual-layer design, with both an air pump and a fuel pump, mixes the air and fuel in the burner head chamber and then pushes the mixture to the multi-hole injection igniter 16. After ignition, the fan replenishes oxygen and provides upward thrust. The heat from combustion vaporizes the mixed fuel in the high-temperature vaporization chamber 18 and low-temperature vaporization chamber 17 of the burner head. In extremely cold weather or when fuel cannot be vaporized, a double-layer air intake device and a leak-proof cap prevent fuel from entering the stove through the air vent, ignition needle, and extinguishing needle fixing pipe 7, thus preventing accidents. This effectively solves the safety and emission problems of traditional alcohol-based fuel stoves, such as fuel leakage, lack of smoldering flame, substandard combustion emissions, and high energy consumption. The two horizontally arranged inlets include a check valve on the air inlet to prevent fuel from flowing back to the pump and causing backfire. A sealed steel ball is placed in the fuel inlet for one-way combustion. Fuel is lifted by the oil pump and flows through the check valve to the device for combustion, preventing backflow. This effectively solves the fuel backflow problem of traditional alcohol-based fuel stoves. In household dual-burner stoves, this prevents fuel from competing with each other, effectively solving the problem of inconsistent flame sizes between the burners.
