Description

Technical Field

[0001] The present invention relates to the technical field of liquid fuel burning appliances, and in particular to a control unit of a liquid fuel vaporization system device. Background Art

[0002] Promoting the market-oriented application of methanol in accordance with local conditions will help explore diversified energy development paths and thus ensure national energy security.

[0003] Domestic companies and industry experts are researching the use of liquid fuels such as alcohols, white oil, and vegetable oil in hotels, food stalls, and other locations. Home kitchens are also beginning to promote the use of liquid fuels. Currently, liquid fuels such as methanol, white oil, and vegetable oil all use gravity and direct injection combustion schemes. These have advantages such as easy ignition after atomization and strong flame power. However, they suffer from high fuel consumption, difficulty adjusting to a low flame, and are prone to leakage and nozzle clogging. In recent years, many have begun experimenting with electric heating methods, known as electrospray vaporization and electrospray devices. These alleviate the high fuel consumption issue, but suffer from long-term reliance on external electrical heating, and are prone to leakage, clogging, and difficulty adjusting to a low flame. A relatively effective approach involves adding an air source to the oil line, where air and fuel are mixed and burned in the pipeline. This solves the problems of clogging and difficulty adjusting to a high or low flame after heating. However, the fuel is affected by the mixing chamber space, resulting in unstable flames. Furthermore, reduced air pressure can cause the liquid fuel to flow back into the gas source pipeline. In light of this, we propose a control unit for a liquid fuel vaporization system.

The injector mounting column is opened at the center position of the base. The ignition needle mounting column, the flame sensor mounting column and the air inlet column are provided with several columns surrounding the outside of the injector mounting column, and several fixing holes are arranged in a ring shape at the end of the base.

[0009] Preferably, a fan fixing frame is connected to one side of the bottom end of the base, an air duct is provided at the position of the bottom end of the base relative to the injector mounting column, and a plurality of fixing columns are also provided at the bottom end of the base; a connecting pipe is provided at the position of the bottom end of the base relative to the high and low temperature through holes, one end of the connecting pipe is connected to the high and low temperature through holes, and the other end of the connecting pipe is connected to the injector mounting column.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The present invention sets high and low temperature through holes in the upper high-temperature layer vaporization cavity, with the inlet higher than the inner surface of the high-temperature layer vaporization cavity.

[0013] 2. The present invention mixes fuel and air in high and low temperature through-holes, creating a more reasonable mixing space. The air-fuel mixing ratio is easily adjusted, and the high-temperature layer is heated more evenly. The heat absorbed by the fuel during vaporization does not affect the fuel vaporization temperature. The fuel vaporized by the high-temperature layer absorbs heat and enters the low-temperature layer without further heat absorption, resulting in uniform temperature, uniform combustion, and uniform flame. Compared with vaporized fuel, liquid fuel is more difficult to intercept. When the air source pressure decreases and the fuel pump has a certain pressure, the presence of a check valve will cause the fuel to flow back to the air source pump, posing a safety hazard.

The eye of the cyclone device forms a right angle or an oblique angle with the air inlet column. The flat wind device can be set to form a right angle or an oblique angle with the air inlet column, or it can be set in a straight-through manner. The fixing hole 2045 is used to connect the vaporization chamber bottom shell 2023.

[0033] It is worth noting that, see Figure 5 A fan mounting bracket 2046 is connected to one side of the bottom of the base 204. An air duct 2047 is provided at the bottom of the base 204, opposite the injector mounting post 2041. Several fixing posts 2049 are also provided at the bottom of the base 204. A connecting pipe 2048 is provided at the bottom of the base 204, opposite the high and low temperature through-holes 2024. One end of the connecting pipe 2048 is connected to the high and low temperature through-holes 2024, and the other end of the connecting pipe 2048 is connected to the injector mounting post 2041. In the present invention, the fan mounting bracket 2046 is used to mount the fan, aligning the fan with the air duct 2047. The fixing posts 2049 are used to secure the base 204 to the bottom shell 3.

[0034] It is worth noting that Figure 7 As shown, the bottom shell 3 includes a shell 304, a heat shield A305, and a heat shield B306.

[0035] Working principle: The present invention sets the vaporization chamber 202 as a high-temperature layer vaporization chamber 2021 and a low-temperature layer vaporization chamber 2022, and sets an air inlet column mounting hole 2025 and a fuel inlet column mounting hole 2026 on the high-temperature layer vaporization chamber 2021. The high-temperature layer vaporization chamber 2021 and the low-temperature layer vaporization chamber 2022 are communicated, and air and fuel are output to the heater mounting part 203 through the high and low temperature through holes 2024. After the air and fuel are vaporized through the vaporization chamber 202, they are output through the high and low temperature through-holes 2024 to the igniter 2031 of the heater mounting part 203 for spraying. Since the base 204 is provided with an injector mounting column 2041, an ignition needle mounting column 2042, a flame sensor mounting column 2043, an air inlet column 2044 and a fixing hole 2045, the injector mounting column 2041 is used to install the flame injector, the ignition needle mounting column 2042 is used to install the ignition needle, the flame sensor mounting column 2043 is used to install the flame sensor, and the air inlet column 2044 is used to install a cyclone device (the main purpose is to form a cyclone fire) or a flat wind device. The eye of the cyclone device forms a right angle or an oblique angle with the air inlet column. The flat wind device can be set to form a right angle or an oblique angle with the air inlet column, or it can be set in a straight-through manner. The fixing hole 2045 is used to connect to the vaporization chamber bottom shell 2023. The fan mounting bracket 2046 at the bottom end of the base 204 is used to mount the fan, which is aligned with the air duct 2047. The fixing column 2049 is used to secure the base 204 to the bottom shell 3. By positioning the high and low temperature through-holes 2024 in the upper high-temperature layer vaporization chamber 2021, with the inlet higher than the inner surface of the high-temperature layer vaporization chamber 2021, the fuel is directly vaporized or flows into the low-temperature layer vaporization chamber 2022. The vertical arrangement of the check valve 205 effectively prevents fuel from flowing back to the gas source pump, lengthens the vaporization path, and effectively solves the problem of fuel deposition and blockage in the vaporization chamber.
