Problems solved by technology
[0005] (1) Inconvenient to use
When refueling, you must always observe whether there is fuel flowing out of the exhaust pipe. When refueling a large aircraft, it takes a long time and is even more troublesome;
[0006] (2) Waste of fuel
Since the phenomenon of fuel discharge is a sign to confirm the completion of refueling, excess fuel must be discharged every time refueling, resulting in fuel waste;
[0007] (3) There is a fire hazard
Aircraft fuel is a flammable liquid. If there is a fire source near the aircraft, it is easy to ignite the aircraft and even cause a fire;
[0008] (4) Pollution of the environment

Embodiment Construction
[0035] Below in conjunction with accompanying drawing, the present invention is explained and illustrated in detail 。 figure 1 It is a schematic diagram of the system of an automatic refueling pump for model airplanes of the present invention. figure 2 It is a schematic diagram of the structure of the automatic fuel pump.
[0036] As can be seen from the accompanying drawings, the basic thinking of the present invention to realize automatic refueling is as follows: first drain the remaining fuel oil in the fuel tank, and the sign that the fuel oil is drained is that there is no fuel in the fuel filler pipe. Then turn to fuel filling, and fill the corresponding volume of fuel according to the capacity of the fuel tank. In order to realize automatic refueling, it is necessary to measure the fuel flow and detect whether there is fuel in the refueling pipe. For the measurement of the fuel flow, the measurement of the motor speed is used to indirectly measure the flow without a...

An automatic refueling pump for model airplanes, including an oil pot and a fuel tank, wherein the fuel pot is a fuel depot for extracting fuel before flying; the fuel tank is a container for storing fuel in the aircraft; it also includes an automatic fuel pump, The automatic refueling pump is composed of a refueling pump and an electronic circuit thereof: the refueling pump is an electric pump, and the electronic circuit part is composed of a microprocessor, a display, buttons, a light transmittance detector, a motor speed module, Compatible with the motor control module. The invention has the following advantages: (1) It overcomes the inherent disadvantages of the existing fuel pumps, realizes automatic refueling, is convenient to use, saves fuel, has no danger of fire, and does not cause environmental pollution. (2) No special flow meter is used, and the structure is compact.
Description
technical field [0001] The invention relates to an automatic refueling pump for model airplanes, belonging to the field of electromechanical products. Background technique [0002] Model airplanes are small aircraft that are popular among teenagers. There are two types of model airplanes in terms of power: battery power and fuel power. Among them, fuel-powered aircraft use piston engines or jet engines as power equipment, referred to as oil-powered aircraft. Oil-powered aircraft generally use methanol, gasoline or aviation kerosene as energy sources. Fuel tanks are placed inside the aircraft, with volumes ranging from 0.1 liters to 5 liters. There are three oil pipes connected to the fuel tank, which are oil filling pipe, oil supply pipe and booster pipe. One end of the booster pipe is connected with the fuel tank, and the other end is communicated with the booster port of the exhaust pipe. When refueling the aircraft, the refueling pump injects fuel from the aircraft re...
