Description

Technical Field

[0001] The utility model relates to the technical field of stove fuel supply, in particular to a stove water-based fuel supply system. Background Art

[0002] The fuel used by existing conventional stoves is generally gas fuel, such as diesel stoves, coal stoves, methanol stoves, liquefied gas stoves, etc. In daily use, there are problems such as scattered firepower, unstable firepower when small fire, and easy fire extinguishing.

[0003] In recent years, as a new type of environmentally friendly clean fuel, water-based fuel has become a new type of kitchen boiler fuel. It is an environmentally friendly fuel mainly made of ordinary chemical products as raw materials. It does not contain methanol, is not a dangerous chemical, cannot be directly ignited by open flames, and is non-flammable, non-explosive, non-toxic, safe, clean and renewable fuel. However, fluid fuel needs to be atomized before it can be burned, and the existing conventional stove system cannot use water-based fuel, which limits the promotion of water-based fuel.

[0004] To this end, we have designed and developed a fuel supply system that can use water-based fuel for conventional stoves. Multiple gas path regulating valves are used to adjust the air and fuel flow, so that a controllable negative pressure gas path is generated in the injection nozzle. Negative pressure suction is used to draw the flammable liquid into the combustion chamber in the form of mist, and mix it with the air to form a flammable mixed gas. The mixed gas can be easily ignited by the high-strength igniter of the stove. The system can be used in conjunction with existing stoves to facilitate the promotion and application of water-based environmentally friendly fuels, reduce the use cost of merchants and the living expenses of users, and is highly practical. Utility Model Content

[0005] The utility model aims to provide a water-based fuel supply system for a stove to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A water-based fuel supply system for a stove includes a storage box, a fuel delivery pipe, a mixing nozzle and an air delivery pipe connected to the mixing nozzle, the mixing nozzle includes a fuel nozzle and an air nozzle sleeved on the outside of the fuel nozzle, the air outlet of the air nozzle is located in front of the fuel nozzle outlet, the storage box outlet is connected to the fuel control valve and the fuel nozzle in sequence through the fuel delivery pipe, the air delivery pipe is connected to the air nozzle, and the air delivery pipe is provided with an air control valve and a vacuum pump.

[0008] As a further preferred solution of the utility model: the fuel control valve includes a fuel main control valve and a fuel sub-control valve which are arranged in parallel on the fuel delivery pipe. The fuel main control valve is used to control large-flow fuel delivery, and the fuel sub-control valve is used to control small-flow fuel delivery.

[0009] As a further preferred solution of the utility model: the air control valve includes a main control air valve and a secondary air valve which are arranged in parallel on the air delivery pipe, the main control air valve is used to control the large-flow air delivery, and the secondary air valve is used to control the small-flow air delivery.

[0010] As a further preferred solution of the utility model: a first solenoid valve located between the storage box and the fuel control valve is arranged on the fuel delivery pipe, and a second solenoid valve located between the vacuum pump and the air control valve is arranged on the air delivery pipe.

[0011] As a further preferred solution of the utility model: an air inlet filter is provided at the air inlet end of the air delivery pipe.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The water-based fuel supply system is designed with fuel nozzles and air nozzles that are matched with each other in an inner and outer arrangement to form a mixing nozzle. When the air delivery pipe delivers air to the air nozzle, a negative pressure space is formed at the discharge port of the fuel nozzle, so that the water-based fuel is sprayed out from the fuel nozzle in atomized form by negative pressure suction, and after mixing with the air, it enters the stove combustion chamber in the form of mist, and can be easily ignited by the high-strength igniter in the stove combustion chamber, so that the water-based fuel can adapt to more stoves and is easy to promote and use; at the same time, by designing parallel control valves, the system can control the flow of fuel and air more flexibly and accurately, so that the mixing nozzle is stable when spraying a smaller flow of mixed fuel, so that the stove head will not be easily extinguished when maintaining a low fire power, and the stove head can retain the fire without repeated ignition.
