Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a cartridge type oil tank for oil heating equipment such as oil stoves.

2. Description of the Related Art A conventional cartridge tank has a structure in which a viewing window 12 is provided at the top of a 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 drawbacks of the above conventional example,
When a tank becomes full due to refueling, it is notified by notification to prevent oil from overflowing and also to allow the oil to be used to the end.

Means for Solving the Problems In order to solve the above problems, the present invention includes a fuel filler port 2 provided at the top of the box body 1, and a lid 4 that opens and closes the fuel filler port and has an oil outlet 3 in the center. and fuel filler port 2
It has a cylinder that can be slid freely inside the tank and is open at both ends, and this cylinder is equipped with a stopper to prevent it from slipping out of the fuel filler port, and a small sounding device is attached to the side that makes a sound when air flows through the cylinder. The tube has a hole, and a part or the whole of the tube is composed of a float floating on oil, and a seal is provided between the stopper and a portion where the stopper abuts the inner surface of the box, and the tube is moved in the box. The configuration was such that a cylindrical stand was provided to limit the range.

Function: With this configuration, when the tank is almost full when refueling, the sounding element operates to notify the full state with sound. Further, although a cartridge tank is normally placed in a combustor or the like with a lid placed upside down and the oil flowing out from the oil outlet is used, no oil remains in the oil tank at this time.

Embodiments 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, lid 4 is used for refueling.
In this state, the cylinder 5 is inscribed in the fuel filler port 2 provided at the top of the box 1. The cylinder 5 is usually a flat plate provided at the top of the box 1.
and rides on the cylinder stand 11 having a large number of holes 11a,
This prevents the tube 5 from falling into the interior. Further, a stopper 6 provided on the outer periphery of the cylinder 5 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 below the cylinder base 11, the oil is supplied from the oil filler port 2 through the cylinder 5 as in normal oil supply, and the air accompanying this also flows out through the cylinder 5.

When the oil reaches the cylinder base 11 or higher, 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. Seal material 10
The cylinder 5 may also be used.

At this point, if oil continues to be supplied, air corresponding to the increase in oil in the oil chamber A will come out of the cylinder 5 from the sounding device 7 through the small hole 8 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 up by the float 9 to the upper cylinder stand 11, and since the stopper 6 is separated from the sealing material 10, all the oil flows out from the oil outlet 3. Therefore, there is no residual oil when using oil.

Effects of the Invention As explained above, the cartridge-type oil tank of the present invention uses a sound device to notify 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 a dark place. , even visually impaired people can safely refuel without spilling oil. Furthermore, the timing at which the sounding device starts notifying can be freely designed depending on the length of the cylinder, so even if the size, vertical length, horizontal length, etc. of the tank are different, the timing can be set at the optimal timing.

Furthermore, the tube operates reliably because it operates using the buoyancy of the float, and when refueling the tank or using oil, the usability remains the same as with conventional cartridge tanks, and it can be used until the tank is empty, eliminating residual oil. It also has the effect of being easy to remove oil.
It has great industrial value.
