Description: BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to an oil weighing machine that can divide and sell oil by using an oil container such as a pail can. 2. Description of the Related Art Conventionally, oil for motorcycles can be purchased and used in a supermarket or the like in a small capacity container such as 0.5 liter or 1 liter. Such small-sized oil cans can be easily used personally at home and the like, but may cause pollution of cans and increase the cost of purchasing oil. In order to reduce can pollution and reduce costs when purchasing oil, auto repair shops and motorcycle dealers have replaced large conventional pail cans with a capacity of about 20 liters instead of conventional small oil cans. The company plans to use the oil contained in the oil container and sell the oil in small portions. [0003] However, when an oil suction section is attached to an oil container such as a pail can having a large capacity and oil is sucked up by a pump and oil is supplied from an oil supply nozzle, the inside of the can is negatively charged at the time of oil supply. If the pressure is reached or air is sucked in until the residual oil is exhausted, air will be mixed in and the measurement will be poor.Therefore, a certain amount must be left, and the remaining oil in this can needs to be transferred to the next new can. There was a risk of contamination. Accordingly, the present invention provides an oil weighing machine which is free of dirt such as oil, can prevent negative pressure inside the can at the time of refueling, can reduce residual oil, and can prevent the occurrence of measurement failure due to air mixing.
