DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a lid opening / closing device for a filler port of a cartridge tank of an oil heater, for example.

[Prior Art] FIG. 5 is a perspective view showing a relationship between cartridge tanks of an oil heater, and FIG. 6 is a perspective view showing a cap portion of the cartridge tank. In the figure, (1) is an oil heater, and an accommodating portion (3) for a cartridge tank (2) is provided therein. (4) is a container of a cartridge tank, which is provided with an oil meter window (5) so that the amount of fuel can be confirmed. (6) is a tank mouthpiece that serves as an inlet for fuel, and a fuel filler lid (7) is removable with a roll screw. The fuel filler lid (7) is provided with a valve portion (8) through which fuel can be discharged to the outside.

Next, this action will be described. In order to operate the oil heater (1), when fuel is put in the cartridge tank (2) and attached to the storage part (3) of the oil heater (1), the valve part at the tip of the oil filler cap (7) is installed. The fuel in the cartridge tank (2) is sent to the combustor inside the oil heater (1) via (8) and is ignited by the ignition device to start combustion. When the fuel is exhausted in this way, a message prompting refueling is displayed on the oil meter provided in the oil heater (1). In order to replenish the fuel, take out the cartridge tank (2) from the storage section (3), stand it up with the tank mouthpiece (6) facing upward as shown in FIG. Turn to remove, refuel from tank cap (6), and check this with oil gauge window (5). After refueling, attach the fuel filler cap (7) to the tank base (6).
Then, it is fastened with a roll screw so that the oil supply port cover (7) is placed downward as shown in FIG. 5, and it is installed again in the accommodation part (3) of the oil heater (1).

[Problems to be solved by the invention] Since the tank base (6) and the filler cap (7) are configured in this manner, the tank cap (6) is provided with the filler cap (7).
When a person touches the filler cap (7) to attach and detach the fuel filler, there is a problem that the fuel oil attached to the valve portion (8) of the filler cap (7) gets on the hand or drips on the floor.

For this reason, a method of covering the filler cap (7) with a rubber cap and indirectly rotating it has been considered, but this also causes a problem such as slippage when fuel oil adheres and the filler cap (7) is not tightened sufficiently. was there.

The present invention has been made in order to solve such a problem, and the fuel filler lid can be easily attached and detached, and the fuel supply work can be easily performed without the fuel oil sticking to the hand. The purpose is to obtain a palate opener.

[Means for Solving the Problems] A lid opening / closing device for a fuel filler according to the present invention has a recess fitted to a fuel filler lid that is attached to and detached from a tank cap of a cartridge tank, and the fuel filler lid is provided on the inner surface of the recess. In addition to providing a groove that engages with the above-mentioned projection, an opening is provided at the bottom of the recess and this opening is closed with a non-magnetic plate so that the magnetic force acts in the direction to adsorb the filler cap and extends to both inside and outside. A permanent magnet is fixed to the outside of the non-magnetic plate, and a part of the permanent magnet is projected to the outside from the outer surface of the bottom.

[Operation] In the present invention, after the lid opening / closing device is fitted on the filler opening lid and fitted, if this is rotated, the protrusion of the filler opening lid is caught in the groove on the inner side surface of the lid opening / closing tool and the filler opening lid rotates together with the lid opening / closing tool. Come to do. As a result, the filler cap is attached to and detached from the tank base. Further, when the fuel filler cap is removed from the tank cap, the valve portion of the fuel filler lid is magnetically attached to the magnet of the lid opening / closing tool and therefore does not fall off.

[Embodiment] FIG. 1 is a perspective view of a lid opening / closing tool of the present invention before mounting, and FIG. 2 is a sectional view showing a fitted state of the lid opening / closing tool and a filler cap.
In the figure, (9) is a fuel filler cap with a protrusion attached to a tank mouthpiece (6) fixed to a container (4) of a cartridge tank, and a plurality of protrusions (10) are provided on the outer peripheral surface thereof. (11) is a lid opening / closing tool made of a non-magnetic material, which has a bell shape having a concave portion, and the concave portion is formed so as to fit the oil filler cap (9) with a projection, and the inner peripheral surface of the concave portion is further formed. A groove (14) for locking the protrusion (10) provided on the outer peripheral surface of the oil filler cap with protrusion (9) is provided. An opening (11a) is provided at the bottom of the recess, and a nonmagnetic plate (13) is attached to the opening (11a) so as to close the opening (11a). A permanent magnet (12) is fixed to the plate (13) so that a part of the permanent magnet (12) projects from the outer surface of the bottom of the recess.

A structure may be considered in which the permanent magnet (12) directly contacts the valve portion (8) of the oil supply port lid with projection (9), but the oil supply port lid with projection (9) is pressed when the oil supply port with projection (9) is opened and closed. Since the force is directly applied to the permanent magnet (12), a brittle magnet may break. Therefore, it is conceivable to attach the permanent magnet (12) to the bottom of the recess of the lid opening / closing tool (11) via a plate. In this case, if this plate is made of a magnetic plate, the permeation magnetic force is hindered, and the suction force of the valve portion (8) of the oil supply port lid with protrusions (9) weakens. On the other hand, if it is formed of a non-magnetic plate, the attraction force of the valve portion (8) can be strongly maintained, and a strong magnet need not be used. (15) is a hooking claw described later.

Next, this action will be described. Cartridge tank (2)
When refueling, the lid opening / closing tool (11) configured as described above is put on the oil supply port lid (9) with a protrusion attached to the tank base (6) of the container (4) of the cartridge tank. As a result, as shown in FIG. 2, the oil filler cap with projection (9) is fitted in the recess of the lid opening / closing device (11), and at the same time, the protrusion (10) of the oil filler cap with protrusion (9) is closed with the lid opening / closing device (11). It is inserted into the groove (14) provided on the inner peripheral surface of the to prevent rotation. Further, the magnetic force of the permanent magnet (12) acts on the valve portion (8), and the valve portion (8) is attracted to the permanent magnet (12). When the lid opening / closing tool (11) is turned in this state, the protrusion (10) of the oil supply port lid with protrusion (9) is locked in the groove (14), so that the oil supply port lid with protrusion (9) also rotates and the protrusion is attached. The filler cap (9) is removed from the tank base (6). At this time, since the valve portion (8) is attracted to the permanent magnet (12), the protrusion-added filler cap (9) is held without being separated from the lid opening / closing tool (11).

When attaching the oil filler cap with projection (9) to the tank mouthpiece (6), cover the tank mouthpiece (6) with the lid opening and closing tool (11) in this state and rotate it in the direction opposite to the front to easily install the tank mouthpiece. It is possible to attach the protrusion-added filler cap (9) to (6).

After attaching the oil supply port lid with protrusions (9) to the tank base (6), the lid opening / closing tool (11) has a permanent magnet (12) protruding from the lid opening / closing tool (11) as shown in FIG. Use it to make it stick to the outer iron plate (16) of the oil heater (1),
Alternatively, as shown in FIG. 4, it is convenient to hook the hook (15) in the hole of the iron plate (16) and store it.

[Advantages of the Invention] As described above, the lid opening / closing tool of the present invention according to the present invention has a recess that is fitted into the fuel filler lid that is attached to and detached from the tank cap of the cartridge tank, and is provided on the fuel filler lid on the inner surface of the recess. In addition to providing a groove that engages with the above-mentioned projection, an opening is provided at the bottom of the recess and this opening is closed with a non-magnetic plate so that the magnetic force acts in the direction to adsorb the filler cap and extends to both inside and outside. Since the permanent magnet is fixed to the outside of the non-magnetic plate, and a part of the permanent magnet is projected to the outside of the outer surface of the bottom, the protrusion of the filler neck is hooked in the groove of the lid opening / closing tool, and the lid opening / closing tool is also used. The permanent magnet's magnetic force acts on the refueling port lid in a direction to attract the refueling port lid to prevent the refueling port lid from coming off from the lid opening / closing device, and the lid opening / closing device can be attached to the refueling port lid. Easy to put on and take off It is possible to prevent adherence to a trader and dripping on the floor. Further, the work for tightening the fuel filler cap can be easily and sufficiently performed by the lid opening / closing tool, and the fuel supply work can be facilitated.

Furthermore, the bottom opening of the recess is closed with a non-magnetic plate, and a permanent magnet is attached to this non-magnetic plate, so the attraction force of the valve portion of the oil filler cap with protrusions can be kept strong, so no strong magnet is used. However, the purpose can be achieved sufficiently. Further, since the filler cap does not directly contact the permanent magnet, it is possible to protect the permanent magnet, and also to protect the permanent magnet from deterioration and peeling due to liquid fuel such as an adhesive that fixes the permanent magnet.
The quality of the lid opening / closing tool can be improved.

Also, by using a permanent magnet protruding from the lid opening / closing tool, for example, it can be adsorbed and stored on the outer iron plate of an oil heater, so it can be used immediately when desired, and a convenient lid opening / closing tool can be used. Obtainable.
