Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an oil change machine used when changing automobile oil.

[Prior art] When replacing old automobile oil with new oil, when supplying oil from an opaque tank such as a steel can, it is not possible to check the amount of oil in the tank from the outside. Therefore, work errors such as supply interruptions due to oil shortages were likely to occur.

[Problems to be Solved by the Invention] An object of the present invention is to provide an oil change machine that allows easy confirmation of the amount of oil in an opaque tank.

[Means for Solving the Problems] In order to solve the above problems, the present invention provides an oil exchange pump driven by a prime mover, a tank filled with oil, and a method for knowing the amount of oil in the tank. a transparent gauge tube, the proximal end of which is inserted into the tank through the opening, and the distal end of which extends downwardly outside the tank to near the bottom of the tank; It is characterized by being folded upward and opening at a position slightly higher than the tank, and being connectable to the pump.

[Operation] When the pump is operated by an electric motor and the pump fills the gauge pipe with oil, the liquid level of the oil in the gauge pipe becomes the same as the oil level in the tank.

In this state, new oil is supplied from the tank while draining the old oil from the car. Here, when the amount of oil in the tank decreases, the liquid level of the oil in the gauge tube also decreases, so the amount of oil in the tank can be known from the outside through the gauge tube.

[Example] Hereinafter, an example of the present invention will be described in detail based on the drawings.

A supply pump 2 for supplying new oil to the car and a discharge pump 3 for sucking and discharging old oil from the car are provided on the body 1. These pumps 2 and 3 are driven by an electric motor 4 through a belt 5. It is becoming driven.

Suction port 2a and discharge port 2b of the supply pump 2
A suction pipe 6 and a discharge pipe 7, which are elastic, are respectively connected to the suction pipe 6 and a discharge pipe 7, which are also elastic.
is connected. The suction pipe 6 of the supply pump 2 is inserted into the tank 10 placed on the aircraft body 1.
It is inserted through a locking piece 11 which also serves as a cap attached to the opening, and its tip reaches near the bottom of the tank 10.

The tank 10 also includes a transparent gauge tube 1.
2 is attached, and the gauge tube 12 is inserted into the tank 10 so that its base end 12a reaches the bottom of the tank 10 through the opening, and the tip end 12b is inserted outside the tank 10. , once extending downward to near the bottom of the tank 10, and then folded back upwards to open at a position slightly higher than the tank 10. The gauge tube 12 and the suction tube 8 of the discharge pump 3 can communicate with each other.

When changing oil using the oil changer having the above configuration, each pump 2,
3 is operated, the suction pipe 8 of the discharge pump 3 is communicated with the opening at the tip of the gauge tube 12, and the oil in the tank 10 is sucked through the gauge tube 12. Then, when the suction tube 8 is cut off when the oil 13 reaches the tip of the gauge tube 12, the gauge tube 1
The oil in tank 2 has the same liquid level as the oil in tank 10.

In this state, the old oil in the car is sucked and discharged by the discharge pump 3, and the new oil 13 in the tank 10 is supplied by the supply pump 2. Here, when the amount of oil in the tank 10 decreases, the liquid level of the oil in the gauge tube 12 also decreases.
You can see the amount of oil inside from the outside.

When the oil 13 in the tank 10 runs out, it can be replenished or replaced with another tank.

[Effect of the invention] As described above, according to the invention, since a transparent gauge tube is attached to the tank, the amount of oil in the tank can be easily known from the outside through the gauge tube. This makes it possible to reliably prevent work errors due to oil shortage.

In addition, a gauge tube is formed as a separate member from the tank,
Since this is attached to the tank, one gauge tube can be commonly used for unspecified tanks, which is very economical and convenient.

Moreover, since the gauge tube can be connected to a pump for oil exchange, the pump for oil exchange can also be used for filling oil into the gauge tube. There is no need to prepare a separate filling machine, the structure of the filling machine is simple, and the filling operation is also easy.
