Abstract

PURPOSE:To feed oil stably by forming a small hole where a device generating a sound of the flow of air is fitted to the flank of a cylinder which is freely slidable while inscribed in an oil feed port and open at both ends. CONSTITUTION:When the oil is below a cylinder base 11, the oil is fed from the oil feed port 2 as well as normal oil feeding and air flows out the cylinder base 11, the cylinder 5 is floated by a float 9 and a stopper 6 abuts on the oil feed port 2 to seal an oil chamber A with a seal material 10. When the oil is further fed continuously, the air flows out of the cylinder 5 through the small hole 8 from a sounding device 7 as shown by a dotted-line arrow by the increment of the oil in the oil chamber A and the sounding device 7 operates at this time to generate the sound, indicating that the chamber is nearly filled with the oil.

Description

[Detailed description of the invention] Industrial field of application ``iRelating to a cartridge type oil tank for kerosene heating equipment such as kerosene stoves.

2. Description of the Related Art A conventional cartridge tank has a construction having a viewing window 12 in the upper part of the cartridge tank 1, as shown in FIG. The user refuels from the refueling port 2, and by looking directly at the liquid level B through the peephole 12, he knows when the tank is full and stops refueling.

Problems to be Solved by the Invention In the conventional configuration described above, it is difficult for the user to know when the tank is full in a dark place because the user looks directly at the liquid level B through the peephole 12. There is a problem in that oil may overflow from the filler port 2 of the tank 1.

The present invention solves the above-mentioned drawbacks of the conventional example, and allows the tank to be notified when it becomes full due to refueling, thereby preventing oil from overflowing and allowing the oil to be used until the end.

Means for Solving the Problem In order to solve the problem, the present invention provides a fuel filler port 2 provided at the top of the box body 1, and a lid that opens and closes the fuel filler port and has an oil outlet 3 in the center. 4 and a cylinder that is inscribed in the fuel filler port 2 and is slidable and open at both ends, and this tube is provided with a flange to prevent it from slipping out from the fuel filler port, and also makes noise when air flows through the side. It has a small hole in which a sound generating device is attached, and a part or the whole of the cylinder is made up of a float that floats on oil, and a sealing part is provided at the position where the striker and the paddle come into contact with the inner surface of the box body.

Effect: With this configuration, when the tank is almost full when refueling, the sounding body operates to notify the full state with sound. The cartridge tank is normally placed upside down in a combustor or the like with a lid on, and the oil that flows out from the oil outlet is used, but the cartridge tank has the effect that no oil remains in the oil tank at this time.

EXAMPLES Examples of the present invention will be described below with reference to FIGS. 1 to 3.

FIG. 1 shows a cross-sectional view of the structure of a cartridge type oil tank according to the present invention. Here, the lid 4 is removed for refueling, and in this state, the cylinder 5 is disposed inscribed in the refueling port 2 provided at the top of the box 1. The cylinder 5 is usually a flat plate provided at the end of the box 1, and the cylinder metal 1 has many holes 11a.
1 and prevents the tube 5 from falling into the interior. The sleeve 6 provided on the outer periphery of the cylinder 5 still prevents the cylinder 5 from slipping out from the fuel filler port 2.

Further, the cylinder 5 is provided with a small hole 8 for air venting, and a sounding device 7, such as a flute, which generates sound by air circulation is attached to this small hole 8. Furthermore, floats 9 that float on oil are attached to both ends of the cylinder 5. The float 9 may be formed of a material that allows the tube 5 itself to function as a float.

Now, when the oil is less than 11 in the tube metal, the oil is supplied from the oil filler port 2 through the inside of the tube 5 as in normal oil supply, and along with this, the air is also pumped into the tube 5.
Go inside and go out.

When the oil reaches the cylinder metal 11 or above, the cylinder 5 is lifted up by the float 9 as shown in FIG. 2, and eventually the stopper 6 comes into contact with the oil filler port 2 as shown in FIG. be done. The cylinder 5 may also serve as the sealing material 10.

At this point, if oil continues to be supplied, air corresponding to the increased amount of oil in the oil chamber A will come to escape from the cylinder 5 through the small hole 8 from the sounding device 7, as shown by the dotted arrow. At this time, the sound generating device 7 operates to emit a sound to notify that the oil is almost full.

FIG. 3 shows the state of the box 1 when oil is actually used.

Usually, a cartridge type tank is installed in a combustion device (not shown) with the fuel filler port 2 facing downward as shown in the figure, and the oil flowing out from the oil outlet 3 of the lid 4 is used. At this time, the cylinder 5 is held down by the upper cylinder metal 11 by the float 9, and the stopper 6 is far from the sea) v (10th), so all the oil flows out from the oil outlet 3. Therefore, when oil is used, there is no residual oil. will disappear.

As described in detail, the cartridge type oil tank of the present invention uses a sounding device to alert you with a sound when it is almost full during refueling, so there is no need to pay attention to the refueling window during refueling, and it is possible to refuel in dark places. Even visually impaired people can refuel safely and without spilling oil. Furthermore, the timing at which the sound device starts notifying can be freely designed depending on the length of the short.
Even if the shape of the tank is different, such as size, vertical length, horizontal length, etc., notification can be made at the optimal timing.

Furthermore, the tube operates reliably because it operates using the buoyancy of the float, and when refueling or using oil, the usability remains the same as with conventional cartridge tanks, and the tank can be used until it is empty, with no residual oil. Also, it has the effect of being easy to remove oil, and has great industrial value.
