Description

[Detailed Description of the Invention] The present invention relates to a liquid supply tank used as a cartridge type tank of an kerosene heater.

Conventionally, cartridge-type tanks for kerosene heaters generally have a socket cylinder outside the outlet at one end of the tank body.
A cap having a valve device is removably provided on the socket body, and when the tank body is attached to the kerosene stove, the valve device opens and the oil in the tank body is supplied to the kerosene stove.

For such tanks, if the user notices that the oil has run out while using the kerosene stove, remove the tank from the kerosene stove, carry it to the kerosene storage area, remove the cap, and connect the hose pump from the socket body. After refueling is completed, the cap is reattached and the stove is attached to the kerosene stove.

However, in many cases, the cap is not completely attached when refueling is completed.

If this cap is incomplete and you carry it with the cap facing up and the cap comes off when you try to attach it to the kerosene stove, the full amount of kerosene in the tank may spill onto the burning kerosene stove. There is a danger that a large amount will be applied, leading to a fire.

Of course, the instruction manual for kerosene heaters includes cautions such as extinguishing the fire before refueling, making sure to tighten the cap, and turning the cap downwards to check for oil leaks. In reality, in many cases, fuel is refueled during combustion use, and checks for oil leaks are often neglected.

In fact, quite a few fires have occurred due to these.

In addition, there are strong demands for the safety of these products.
It is desired that even if the cap should come off, there will be no oil leakage that could lead to a fire.

The present invention was developed in consideration of these points.
The purpose is to provide a highly safe liquid supply tank.

The present invention includes a tank body, an outlet provided at one end of the tank body, a socket body provided on the outside of the outlet, and a tank body detachably provided on the socket body. In a liquid supply tank equipped with a cap and a valve device provided on the cap and opened when the tank body is attached to a device for supplying liquid, the outer periphery of the tip is removably attached to the opening edge of the socket cylinder. A valve cylinder body is provided inwardly from the opening of the socket cylinder body, and a through hole in the inner bottom surface of the valve cylinder body has at least an outlet that opens when the tank body is attached to a device for supplying liquid. This device is characterized by being provided with a valve body that closes when the cap is removed with the side facing downward.

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 1 to 3.

Reference numeral 1 denotes a tank body, and the tank body 1 is integrally joined to one side of a triangular casing 2 by winding and seam welding a side plate 3.

Then, an outlet 4 is formed on one end surface of the tank body 1,
A socket cylindrical body 5 protruding outward is fixed to this outlet 4 by caulking or the like, and a cap 7 is screwed into this socket cylindrical body 5 with a packing 6 interposed between the end face of the socket cylindrical body 5. A valve device 8 is provided in the center of the cap 7.

In this valve device 8, a supply port 9 is formed in the center of the end face of the cap 7, a support tube 10 is attached to the inside of the supply port 9, and a replacement hole 11 is bored on the side of the tip of the support tube 10. has been done.

Further, a gasket 12 is provided inside the supply port 9, and a valve 13 for opening and closing the supply port 9 is provided in the support tube 10 so as to be able to move forward and backward, and a valve stem protrudes from the valve 13. 14 penetrates the bottom surface of the support tube 10 and projects into the tank body 1.

A coil spring 15 is stretched between the valve 13 and the inner bottom surface of the support tube 10, so that the valve 13 normally closes the supply port 9 and is hermetically sealed.

Further, a valve cylinder body 16 is attached inward from the opening of the socket cylinder body 5 of the tank body 1.

This valve cylinder body 1°6 is formed of a flexible material such as oil-resistant rubber or visible synthetic resin such as propylene, and has an annular groove 17 formed on the outer periphery of the tip.
A through hole 18 is formed in the center of the inner bottom surface, and a valve body 19 made of a flexible material similar to that of the valve cylinder body 16 is provided in the through hole 18 so as to be openable and closable with a hinge portion 20 at one end. There is.

The valve cylinder body 16 is removably press-fitted into the opening edge 5a of the socket cylinder body 5 through a groove 17 on the outer periphery of the tip.

Then, when the tank body 1 is reversed and attached to the fixed tank 21 of the kerosene heater, the push rod 22 of the fixed tank 21 pushes up the valve 13 through the supply port 9 to open the supply port 9, and then the valve rod 14 to push up the valve body 19 and open the through hole 18.
Open the oil passage hole 18 in the tank body 1, and the replacement hole 11. in the support tube 10. It is supplied into the fixed tank 21 through the supply port 9.

In this case, the valve cylinder body 16 can prevent resonance noise when oil flows in and out, thereby reducing noise.

Furthermore, when the tank body 1 is removed from the kerosene stove and the cap 7 is removed with the cap 7 side facing downward, the valve device 8 is removed together with the cap 7, and the valve body 19 is no longer supported by the valve stem 14. Returned with urging force and passed 18
to prevent kerosene from flowing out of the tank body 1.

Further, when refueling the tank body 1, the valve body 19 is opened by inserting a hose pump or the like into the tank body 1.

Furthermore, the valve cylinder body 16 may be removed when refueling.

Moreover, by engaging the opening edge 5a of the socket cylinder body 5, the valve cylinder body 16 can also have a packing effect depending on its material.

In addition, in implementation, the hinge part 20 of the valve cylinder body 16 is
As shown in FIG. 4, the hinge portion 20 may be formed integrally with the valve body 19 and fixed to the valve cylinder body 16 by welding or the like;
As shown in the figure, it may be attached by a method such as protruding a locking pin 23 from the valve cylinder body 16 and pushing the hinge portion 20 into the locking pin.

Further, as shown in FIG. 6, the valve body 19 is provided to be movable up and down, and when the valve body 19 is lowered, the through hole 18 is blocked.
The passage hole 18 may not be blocked when it is raised.

Furthermore, in practice, when the cap 7 is attached to the socket cylinder 5 of the tank body 1, the valve rod 14 may actuate the valve body 19 to open the through hole 18 when the tank body 1 is inverted. However, when the cap 7 is attached, the valve stem 14 does not operate the valve body 19, and when the valve 13 is pushed up with the push rod 22 after being attached to the fixed tank 21 of the kerosene heater, the valve stem 14 does not operate the valve body 19. Safety can be improved by actuating the opening of the through hole 18.

In addition, this invention can be used in tanks for kerosene stoves, etc.
It can also be used for water dispensers, etc.

According to the present invention, even if the cap should come off when attached to a device, the valve body inside the tank body will instantly close the hole in the valve barrel, and a large amount of liquid inside the tank will flow out. For example, by using it in a cartridge-shaped tank of an kerosene heater, it is possible to prevent fire accidents due to improper handling.

In addition, since the valve cylinder body is attached inward from the opening of the socket cylinder body by removably engaging its tip outer periphery to the opening edge of the socket cylinder body, the valve body is installed inward from the opening of the socket cylinder body. It can be easily configured by attaching a valve body with a valve body to the socket body of the valve body, making it possible to easily make a conventional tank highly safe. Cleaning, inspection, etc. can be easily performed by attaching and detaching.

In addition, when replacing and replenishing liquid by attaching it to the tank body,
The valve cylinder body can prevent resonance noise when liquid flows in and out, thereby reducing noise.
