Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to the structure of the fuel filler cap of a cartridge tank used in oil-burning appliances. This provides a structure to prevent hands from getting dirty.

[Prior Art] A fuel filler cap 12 screwed onto a fuel filler port 11 of a cartridge tank used in a conventional oil-burning appliance is formed in the shape of a cap, and has a valve port that bulges outward at its outer center. A valve stem 14 having a valve body for opening and closing the valve port 13 is formed inside the valve stem 13, a holding member 15 for holding the valve stem 14, and a holding member 15 for holding the valve stem 14, which is attached in the direction in which the valve closes. A spring 16 is installed in each case.

[Problems to be solved by the invention] However, according to the above structure, when the cartridge tank is installed in the main body of the oil burning appliance, the valve port 13 of the fuel filler cap 12 is in contact with the oil surface, so oil does not adhere to it. are doing. Therefore, when refueling, the tank body 17 is pulled up, turned upside down, and the fuel filler cap 12
When the oil filler cap 12 is turned upward, the oil adhering to the valve port 13 flows along the top surface of the oil filler cap 12 to the threaded portion on the side.
This has the disadvantage that if you hold the threaded portion with your hand to remove the fuel filler cap, your hands will get dirty with oil.

[Means for Solving the Problems] The present invention eliminates the above-mentioned drawbacks of the conventional technology, and includes a mesh member or the like formed in a disk shape on the outside of the fuel filler cap so as to surround the valve opening of the fuel filler cap. It is equipped with an oil-impregnated material.

[Embodiment] The present invention will be explained with reference to an embodiment shown in the drawings below. Reference numeral 1 denotes a cartridge tank body, and the bottom of the main body 1 is formed with an oil filler port 2 having a threaded portion. A cap-shaped fuel filler cap 3 having a screw portion that can be freely screwed into the tank is removably screwed onto the tank. The fuel filler cap 3 has a valve port 4 that bulges outward in its center, and inside thereof is a valve stem 5 equipped with a valve body for opening and closing the valve port 4. A holding member 6 that holds the valve stem 5 and a spring 7 that biases the valve stem 5 in the direction in which the valve body closes are provided.
On the other hand, an oil-impregnated material 8 made of one or more mesh-like members formed in a disc shape so as to surround the valve port 4 is installed on the outside of the oil filler cap 3. It is fixed to the outside of the fuel filler cap 3 by screwing a ring-shaped cap 9 with a threaded portion whose outer peripheral edge can be screwed into the threaded portion of the fuel filler cap 3. Reference numeral 18 denotes a main tank of the main body of the oil combustion appliance, and the main tank 18 is formed with a receiving part 19 for receiving the fuel filler cap 3 of the cartridge tank main body 1, and the bottom of the receiving part 19 is provided with a receiving part 19 for receiving the fuel filler cap 3 of the cartridge tank main body 1. A push rod 20 is provided to push up the valve body.

[Function] In the above-described configuration, when the cartridge tank main body 1 is attached to the main body of an oil combustion appliance, the fuel filler cap 3 is received in the receiving portion 19 of the main tank 18, and the valve body of the fuel filler cap 3 is inserted into the valve body. The valve opening 4 is pushed up by the push rod 20 inserted through the opening 4, and the oil in the tank body 1 is supplied into the main tank 18 through the valve opening 4, and the oil level reaches the valve opening 4. When this is reached, the supply will be stopped. In this state,
The valve port 4 is in contact with the oil surface. Therefore, when refueling, when the tank body 1 is pulled up from the main body of the device and turned upside down with the fuel filler cap 3 facing upward, the oil adhering to the valve port 4 flows laterally along the top surface, but this oil is removed from the fuel filler cap. The oil is stored by the surface tension of the oil-impregnated material 8 provided outside the valve part 3 so as to surround the valve part, and is received in the ring-shaped mouthpiece 9.
Oil does not flow out onto the threaded portion on the side surface of the oil filler cap 3, and therefore, oil does not adhere to the threaded portion of the fuel filler cap 3.

[Effects of the invention] As described above, in the present invention, a disc-shaped valve is formed on the outside of the fuel filler cap, which has a valve opening that bulges outward in the center, so as to surround the valve opening. The oil-impregnating material made of a net-like member, etc., is installed, and the oil-impregnating material is fixed by a ring-shaped cap that is screwed onto the fuel filler cap. Even if the valve is turned upside down and the oil filler cap is turned upward, the oil adhering to the valve port will be retained by the surface tension of the oil-impregnated material provided on the outer periphery of the valve port, and will be received within the ring-shaped cap. Unlike conventional products, the oil does not flow into the threaded part on the side of the fuel filler cap and wet that part, and even if you hold the threaded part of the fuel filler cap in your hand, your hands will not get dirty with oil. .
