Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a petroleum fuel supply device such as a petroleum stove, and more particularly to a petroleum fuel supply device having an improved oil supply tank and an oil pan.

[0002]

2. Description of the Related Art In a conventional petroleum fuel supply system, as shown in FIGS.
Is set, the fuel tank 3 and the combustion tank 2
The oil supply cap 6 provided for the supply to the oil was immersed in the oil.

When the fuel tank 3 is set in the combustion tank 2, the fuel cap 6 of the fuel tank 3 is below the oil level of the combustion tank 2 and almost half of the fuel cap 6 is immersed in oil. At this time, when the oil supply tank 3 was taken out of the appliance, the oil remained on the outer periphery and the bottom surface of the oil supply cap 6.

[0004]

With the above-described conventional petroleum fuel supply apparatus, when oil is supplied to the oil supply tank, the hands may be contaminated with oil unless the oil adhering to the outer periphery of the oil supply cap is wiped off. There have been problems such as oil drops and oil drops spilling.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and has as its object to provide an oil fuel supply system capable of avoiding the operation of wiping off oil adhering to an oil supply cap when oil is supplied to an oil supply tank. It is to provide a device.

[0006]

The petroleum fuel supply device of the present invention has been made in order to solve the above-mentioned problem. A movable cylinder urged upward by a spring is provided in an oil receiving tray, and a movable cylinder is provided. The upper opening of the cylinder is in close contact with the oil outlet of the oil supply cap of the oil supply tank when the oil supply tank is installed, so that the liquid flows through the movable cylinder, and the liquid does not adhere to the end face and outer periphery of the oil supply cap. It becomes.

In the above configuration, when the oil supply tank is set in the combustion tank of the petroleum fuel supply device, the oil outflow path extends from the tip of the oil supply cap through the movable cylinder to the combustion tank. In addition, when the fuel tank is detached, the movable cylinder extends upward. At this time, the valve in the cap of the fuel tank has already been closed. In this case, the oil level of the combustion tank is the same at the time of setting and removing the fuel tank. or,
The contact between the valve and the push-up pin is in contact with the convex and concave portions of the semicircle, so that the adhesion of the liquid is extremely small.

[0008] By the above operation, the oil supply cap of the oil supply tank does not accumulate liquid, and the wetted area is extremely small.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a petroleum fuel supply apparatus according to the present invention will be described below with reference to FIGS. 1 to 6. The same parts as those in the above-mentioned conventional example are denoted by the same reference numerals.

FIG. 1 is a cross-sectional view of a fuel supply unit in a state where a fuel tank is set in a combustion tank of the present invention, FIG. 2 is a cross-sectional view of a fuel supply unit in a state where the fuel tank is detached from the combustion tank, and FIG. 4 is a perspective view of the same oil receiving tray, FIG. 5 is an exploded perspective view of the same oil receiving cap, and FIG. 6 is a partially cutaway perspective view of the same oil receiving tray.

The outline of the oil supply tank and the oil pan of the petroleum fuel supply device of the present invention will be described mainly with reference to FIG.
As shown in FIG. 4 to FIG. 4, the core inner cylinder 10 erected on the bottom of the combustion tank 2 and the core outer cylinder 12 mounted on the upper part of the combustion tank 2 via packing are guided so as to be movable up and down. A wick 11 is provided. On the right side of the upper surface of the combustion tank 2, an oil receiving tray 1 provided with a push-up pin 5 for opening the valve 8 of the oil supply cap 6 and a guide cylinder 13 for guiding the movable cylinder 4 is provided in the center. I have. The guide cylinder 13 is provided with a slot 131. This guide cylinder 13 has a compression spring 1
The movable cylinder 4 is incorporated via 6. Movable cylinder 4
The key portion 41 at the lower end is movably mounted in the slot 131 of the guide cylinder 13. The upper end of the slot 131 is closed, and the key portion 41 of the movable cylinder 4 comes into contact with the slot. Further, a rubber contact ring 17 is attached to the upper end of the movable cylinder 4 so as to make close contact with the oil outlet 7 of the oil supply cap 6. An oil supply tank 3 can be detachably attached to the oil receiving tray 1.

Next, a tank screw 18 provided with a male screw is fixed to the refueling tank 3. A female screw is provided on one side of the refueling cap 6, and inside the refueling cap 6,
Valve 8 with O-ring 15 mounted, valve support 19, valve spring 1
4. Packing 20 is provided. One of the non-slip cylinders 21 is fitted and fixed to the oil supply port side of the oil supply cap 6.
The other end of the non-slip cylinder 21 has the entire periphery of the edge 211 bent inward at an acute angle. This prevents oil from dropping onto the outer periphery of the non-slip cylinder 21 even when oil adheres to the refueling cap 6 for any reason, and prevents the end face of the non-slip cylinder 21 from touching the hand when the refueling cap 6 is opened and closed, thereby preventing injury. doing. Further, the outer periphery of the anti-slip cylinder 21 is made uneven so that it can be easily opened and closed.

Next, the operation when the fuel tank is mounted will be described.

As shown in FIGS. 1 to 6, when the fuel tank 3 is mounted on the oil pan 1 disposed in the combustion tank 2, a conical outlet 7 at the tip of the oil cap 6 is provided in the oil pan 1. The movable cylinder 4 comes into contact with the tight packing 17. When the movable cylinder 4 is pressed by the weight of the oil supply tank 3, the movable cylinder 4 is moved downward while increasing the adhesion force by the compression spring 16. Further, the oil supply tank 3 is lowered and the push-up pin 5 provided on the oil receiving tray 1 pushes up the valve 8 formed on the oil supply cap 6 so that oil can flow out of the oil supply tank 3. The oil flows through the movable cylinder 4, flows through the slot 131 of the guide cylinder 13, and flows from the spout 9 of the oil receiving tray 1 to the combustion tank 2. When oil accumulates in the combustion tank 2 and the oil level is slightly above the upper end 91 of the spout 9 of the oil receiving tray 1, the inside of the oil supply tank 3 is in a negative pressure state and the oil stops flowing. Therefore, the edge 2 of the non-slip cylinder 21 fitted and fixed to the refueling cap 6
11 does not get wet with oil because it is located higher than the oil level.

Next, the operation when the fuel tank is detached will be described.

When the fuel tank 3 is lifted as shown in FIG. 2, the close packing 9 of the movable cylinder 4 moves upward following the fuel tank 3 while maintaining the close contact state. With this operation, the valve 9, which has been pushed up by the push-up pin 5 of the oil receiving tray 1, comes into contact with the outflow port 7 of the oil supply cap 6 by the pressing of the valve spring 14, and the oil in the oil supply tank 3 flows out. Stop. When the oil supply tank 3 is further pulled up, the movable cylinder 4 is moved by the compression spring 16, and the key 41 provided at the lower end of the movable cylinder 4 is provided at the upper end of the groove 41 of the guide cylinder 13 provided at the oil receiving tray 1. Hits and stops.

[0017]

Since the petroleum fuel supply device of the present invention has the above-described structure, it is provided with a vertically movable movable cylinder provided on the oil receiving tray so as to be in close contact with the oil outlet of the oil supply cap of the oil supply tank. Then, by opening and closing the valve of the oil supply tank, the oil supply cap is wetted with oil only at the valve, and the surface facing the valve and the push-up pin is formed in a shape that matches, so that there is almost no accumulation of oil. Therefore, at the time of refueling, oil drops do not drop when the refueling tank is carried. Further, there is an advantage that the oil supply cap can be opened and closed without soiling the hands with oil.
