JP3233225U - Automatic fuel supply system for portable generators - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide an automatic fuel supply system for a portable generator which can be connected to a plurality of fuel tanks and can replace an empty fuel tank even while the generator is in operation. An automatic fuel supply system includes a fuel supply pump 4 that supplies fuel to a portable generator, a pressure sensor that detects the pressure of a carburetor in the generator connected through a hose, and air when the tank runs out of fuel. Includes a sub-tank that detects the inflow of fuel. A tube pump is used to supply fuel, and a pressure sensor mounted on the control board 3 is used to detect the pressure inside the carburetor in the generator connected through the hose, and the pump stop control is performed by the pressure rise due to the rise of the float. To do. [Selection diagram] Fig. 1

Description

This is a field related to portable generators.

It is natural that portable generators are designed to be as small as possible and easy to carry, but the fuel tanks used are generally of relatively small capacity and are not suitable for long-term operation in the first place.

However, recently, the time required for electricity has increased due to disasters, etc., so there is a need for long-term operation of portable generators. However, simply increasing the size of the fuel tank comes at the expense of portability.

Therefore, we devised a tank exchange type fuel supply device so that it can be connected to multiple fuel tanks and the empty fuel tank can be replaced even while the generator is in operation. An electric pump is used to supply fuel, and a pressure sensor mounted on the control board is used to detect the pressure inside the carburetor inside the generator connected through Ho ㇲ, and the pressure rise due to the rise of the float makes it electric. Controls the stop of the pump. Therefore, modifying the generator simply pulls the fuel hose out. In addition, it is equipped with a sub-tank for bleeding air when the tank is empty to prevent air from being sent to the carburetor.

An electric pump is installed in each tank, and the pipeline is sealed at the stop, so the tank can be replaced even while other tanks are in operation. Also, if you use a product with a one-touch connector for the external tank, you can easily replace multiple tanks, and there is virtually no limit to the fuel capacity.

Fig. 1 is a structural diagram of an automatic fuel supply system for portable generators. Figure 2 is a configuration diagram when using an automatic fuel supply system for portable generators.

More than 1 million portable generators are already on the market, and the annual sales in Japan are about 100,000. By simply attaching this product to those products, the power generation time can be extended to the extent that there is almost no limit while maintaining the performance. This not only enhances the performance of general-purpose portable generators, but also has the potential to extend to applications that were previously unusable, and has great industrial applicability.

Claims (1)

The fuel supply pump is provided by a fuel supply pump that supplies fuel to the portable generator, a pressure sensor that detects the pressure of the carburetor in the generator connected through a hose, and a sub-tank that detects the inflow of air without fuel in the tank. An automatic fuel supply system that combines the stop control of the fuel, and also connects multiple replaceable tanks to continuously supply fuel.
