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 and fan heaters.

2. Description of the Related Art A conventional cartridge tank has a viewing window 14 in the upper part of the cartridge tank 1, as shown in FIG. The user refuels through the refueling port 2, and by looking directly at the liquid level 15 through the peephole 14, the user 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 liquid is full in a dark place because the user looks directly at the liquid level through the peephole. There was a problem in that there was a possibility that the fuel filler port 2 of the tank 1 would overflow.

The present invention solves the drawbacks of the above conventional example,
When the tank becomes full due to refueling, a notification is sent to prevent oil from overflowing, and also to ensure that no oil remains when used.

Means for Solving the Problems In order to solve the above problems, the present invention includes a fuel filler port that opens at the top of the box, a lid that opens and closes the fuel filler port, and a lid that is slidably provided in the fuel filler port. a cylinder with both ends open; a spring that normally presses the cylinder toward the fuel filler port and biases one end of the cylinder to protrude from the fuel filler port when the lid is removed; a stopper for preventing the fuel from slipping out from the fuel filler port; a sealing material provided between the stopper and a portion where the stopper abuts the inner surface of the box; and a sealing material provided at the other end of the cylindrical body located inside the box. and a sounding device that emits a sound when air flows through the small hole, and when the lid is attached to the fuel filler port, the tube moves against the force of the spring, and the stopper and the inner surface of the box body are moved. Means is provided for forming gaps between the cylinder, between the outer surface of the cylinder and the inner surface of the fuel filler port, and between the one end surface of the cylinder and the inner surface of the lid.

Function: With this configuration, when the tank is almost full when refueling, the sounding device is activated to notify the tank with sound that it is full. In addition, a cartridge tank is normally used with the lid on, upside down, and set in a combustor, etc. At this time, oil flows through the gap created by pressing the lid, and no oil remains in the tank.

Embodiments Embodiments of the present invention will be described below with reference to FIGS. 1 to 4.

FIG. 1 shows a cross-sectional view of the structure of a cartridge type oil tank according to the present invention. Here, lid 3 is used for refueling.
A cylinder 4 is slidably disposed inscribed in a fuel filler port 2 provided at the upper part of the box body 1. The tube 4 is always urged upward by a spring 5, so that one end (hereinafter referred to as the tip) A of the tube 4 protrudes beyond the fuel filler port 2 when the lid 3 is removed. Further, a notch 6 is provided at the tip A of the cylinder 4. Further, a stopper 7 provided on the outer periphery of the cylinder 4 prevents the cylinder 4 from slipping out from the fuel filler port 2. A sealing material 9 is disposed where the stopper 7 contacts the box body 1. The other end B side of the tube 4 has a small hole 8 for ventilation, and this small hole 8 is provided with a sounding device 10 that makes a sound when air flows, such as a whistle.

Next, we will explain the operation of each part. Normally, when refueling, the lid 3 is removed with the refueling port 2 facing upward as shown in FIG. 1. At this time, when the oil level is below H, air in the volume of the box 1 corresponding to the oil supply passes through the cylinder 4 and exits as indicated by the arrow P in the figure. However, when the box 1 is almost full of oil and the oil level reaches H or higher, the other end B of the cylinder 4 is immersed in oil and air escapes from the small hole 8 as shown by the arrow Q. At this time, the sound generating device 10 operates to notify by sound that the container is full.

When using oil from the cartridge tank, use the third
As shown in the figure, the box 1 is turned upside down, and the oil dripping from the hole 11 of the lid 3 is used for attaching it to a device (not shown).

At this time, the lid 3 overcomes the force of the spring 5 and pushes the cylinder 4 upward as shown in FIG. 3, and the stopper 7 is separated from the sealing material 9.

Therefore, when the oil level is higher than H, the oil will move to the arrow R in the figure.
It flows through the inside of the cylinder 4 as shown in FIG. When the oil becomes less than I, it flows out from the gap between the cylinder 4 and the oil filler port 2 through the notch 6 of the cylinder 4 as indicated by the arrow S. For this reason, box body 1
All can be used without any oil remaining inside.

FIG. 4 shows another embodiment of the present invention, in which a seat 12 is provided in the middle of the cylinder 4, and a pusher 13 for the cylinder 4 is arranged on the lid 3, so that when the lid 3 is closed, The pusher 13 pushes the seat 12 and pushes the cylinder 4 upward.

This configuration requires a pusher 13 and a seat 12, but as shown in FIG.
Also, when the lid 3 is removed, the tip A of the cylinder 4 is located at the fuel filler port 2.
There's no need to stand out more. In both of the above embodiments, when the lid 3 is attached to the fuel filler port 2, the cylinder 4 moves against the spring 5, and the stopper 7 moves.
The means for forming gaps between the inner surface of the box body 1, the outer surface of the cylinder and the inner surface of the fuel filler port 2, and the inner surface of one end of the cylinder and the inner surface of the lid 3 include the lid 3, the notch 6, or the lid. 3. It includes a pusher 13.

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, making it easier to refuel in dark places and keep your eyes peeled. Even people with disabilities can refuel safely without spilling oil. Furthermore, since the timing to start notification can be freely designed depending on the length of the cylinder, notification can be made at the optimal timing even if the tank size, vertical length, horizontal length, etc. are different.

Furthermore, while oil is being used, the cylinder is pushed up by the lid, allowing it to be used until it is empty, just as if it were without the cylinder, leaving no residual oil and allowing it to be used in exactly the same way as a conventional tank. However, it has great industrial value.
