JP3229120U - Oil supply cap with full oil detection for portable generators - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide an oil supply cap for preventing an oil sensor from operating and stopping the generator when the engine lubricating oil is exhausted in a portable generator. SOLUTION: An oil supply cap is attached to a lubricating oil supply port of a portable generator, and has a passage 3 capable of detecting the full amount of oil by a magnetic sensor 5 and a float 7 with a magnet 8 and supplying oil. A lubricating oil supply cap can be attached, and an extended oil tank or pump can be installed externally to add lubricating oil until the full amount of oil is detected. Ignore the full amount of oil and continue refueling to prevent the engine from malfunctioning due to too much engine oil. [Selection diagram] Fig. 1

Description

This is a field related to long-term operation of 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. Recently, the number of generators that can be operated for a long time by combining them with a separate fuel tank has increased.

However, even with a generator that can be operated for a long time with various ingenuity to extend the power generation time, the amount of engine lubricating oil is currently limited in portable generators, and engine lubricating oil is added. Since it is necessary to stop the engine once, the oil sensor works and the generator stops when the engine oil runs out.

Therefore, it is attached to the lubrication oil supply port of the portable generator, a lubrication oil supply cap with a built-in liquid level sensor, etc. is attached, and an expansion oil tank, pump, etc. are installed externally to lubricate until the full amount of oil is detected. We devised a device that can add oil for use. This is because if you ignore the full amount of oil and continue refueling, the engine oil will become too much and the engine will malfunction. The liquid level sensor uses a magnetic sensor that does not require an external power supply, and when the magnet integrated with the float rises as the oil level rises, the magnetic sensor turns on to notify the outside that the oil is full. I will.

With this cap with engine lubrication oil fullness detection function, you can simply replace the oil supply cap without modifying a commercially available portable generator, and you will not stop due to lack of engine oil, just from the outside. As long as you continue to supply gasoline, you can use it as a generator that can operate continuously.

More than 1 million portable generators are already on the market, and annual sales in Japan exceed 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 expand into applications that could not be used in the past, and has great industrial applicability.
