DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for exchanging oil such as engine oil for automobiles.

[0002]

2. Description of the Related Art For example, at a gas station, an oil changing device for changing engine oil or the like of an automobile is installed. As an example, this oil change device is provided with a new oil tank and a waste oil tank extracted in a case 1 as shown in FIG. 5, and a sampling pipe provided with a sampling pump and an oil supply pump on the way.
One end of the oil supply pipe is opened to the tank, and the other end of the pipe is connected to the oil supply hose 2 or the extraction hose 3 outside the case. Nozzle is detachably mounted.

[0003] A cylindrical nozzle holder 20 for accommodating unused nozzles and nozzles after oil removal or oil supply is completed is provided on the side wall 4 of the case 1.
A dish-shaped oil receiver 21 for receiving oil dripping from the tip of the nozzle immediately after use is provided below the nozzle.

If the nozzle used for changing the engine oil of the automobile as described above is inserted into the nozzle holder 20, the oil dripping from the nozzle holder flows down through the nozzle holder 20, falls into the oil receiver 21, and falls there. Accumulate.

[0005]

Since the nozzle hanger 20 has an opening formed at the lower end of the case 1 in close contact with the case 1, the oil falling through the inside of the nozzle hanger 20 wraps around the bottom, and the outer wall of the case 1 And the floor on which the case and the case are installed are contaminated with oil.

SUMMARY OF THE INVENTION An object of the present invention is to solve the inconvenience of the prior art described above. When a nozzle is hung on the side wall of a case, oil dripping from the nozzle immediately after use can be reliably guided to a lower oil receiver, and the side wall and the base can be guided. It is an object of the present invention to provide an oil changing device which can prevent these parts from spreading and becoming dirty.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention is directed to an oil changer for hooking a sampling nozzle or an oil supply nozzle to a side wall of a case. The notch forms a guide lug for oil dripping from the nozzle tip, and an oil receiver is disposed below the guide lug.

[0008]

According to the present invention, the oil dripping from the nozzle immediately after use flows down the surface of the guide projection formed by the notch, so that the oil surely falls into the oil receiver provided below. Further, since the notch exists on both sides of the guide projection, the oil transmitted through the guide projection does not spread to the side wall or the base by being separated by the notch.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is an exploded perspective view of a main part showing an embodiment of an oil exchange device of the present invention, and FIG. The same components have the same reference characters allotted, and detailed description thereof will not be repeated.

The oil change device of the present invention also draws out the oil supply hose 2 and the extraction hose 3 from the side wall 4 of the case 1, and various types of nozzles 6 can be detachably attached to the tips of the hoses 2 and 3 via the fittings 5. Connect to

In such an oil change device, as shown in a vertical sectional front view of FIG. 3 and a side view of FIG. 4, two vertical notches 7 are provided at a lower portion of the side wall 4, and these notches 7,
7 forms an oil guide projection 4a hanging from the nozzle 6.

Then, a nozzle cover 9 is attached to the side wall 4 at a position above the guide projection 4a and the notch 7. The nozzle cover 9 is a vertically long plate having a U-shaped cross section, and flanges 9a protruding at both left and right ends are attached to the side wall 4, and a space for accommodating the nozzle is formed between the side wall 4 and the flange 9a. In the figure, reference numeral 10 denotes a panel which covers the front of the nozzle cover 9 and is provided on the entire surface of the side wall 4. An appropriate number of nozzle insertion / locking holes 11 are formed in the upper portion of the panel 10.

As described above, the dish-shaped oil receiver 12 is disposed below the nozzle hook formed by the side wall 4, the nozzle cover 9 and the panel 10. This oil receiver 12 is wider than the oil guide projection 4a, and as shown in FIGS. 3 and 4, a support plate 13 attached to the base 1a of the case 1.
A bulging portion 12a is formed on one side wall so as to be curved outward and protrudes. When the bulging portion 12a is disposed on the support plate 13, the bulging portion 12a The arrangement position is determined so as to protrude.

Next, the operation will be described. In order to change the oil of the vehicle, a nozzle 6 corresponding to the gauge hole of the oil pan of the vehicle is selected, and this nozzle 6 is connected to the oil supply hose 2 through the fitting 5. Connect to the end of the sampling hose 3. Then, after the oil change is completed, the nozzle 6 is connected to the hoses 2 and 3 as shown in FIG. Is a stopper and the nozzle 6 is locked to the panel 10.

In this state, the oil dripping from the tip of the nozzle 6 falls directly on the oil receiver 12 or flows down the guide projection 4a, and falls from the tip of the guide projection 4a into the oil receiver 12 therebelow. At this time, since the notches 7 are present on both left and right sides of the guide projection 4a, the oil transmitted through the guide projection 4a separated by the notch 7 does not spread to other portions of the side wall 4 and is surely provided. Oil receiver 12 wider than this
fall into.

Since the bulging portion 12a of the oil receiver 12 protrudes outward from the panel 10, the amount of oil accumulated in the oil receiver 12 can be easily checked from the bulging portion 12a. If the amount of oil in the oil receiver 12 has increased, discard it. In this case, the bulging portion 12a can be used as a knob for pulling out, so that the bulging portion 12a can be easily pulled out from the support plate 13.

[0017]

As described above, the oil change device according to the present invention, in which the nozzle is hung on the side wall of the case,
The oil dripping from the nozzle immediately after use can be reliably guided to the oil receiver below, and can be prevented from spreading to the side wall and the base and contaminating these parts.
