Description
Technical Field
The present invention relates to a fuel gun for refueling a fuel tank (hereinafter referred to as an "in-vehicle fuel tank") of an automobile or the like in a refueling place such as a gasoline station.
Background
The fueling gun is provided at the tip end of a fueling hose led out from a fueling device in a fueling place, and is hung on a gun mount of the fueling device when no fueling is performed. Then, the operator removes the fueling gun from the gun mount and inserts the fueling gun into the interior of the in-vehicle tank or the like, and then drives the fueling mechanism of the fueling device to add the fuel oil.
In recent years, self-service refueling places where the customer performs the refueling operation have become more and more for the purpose of reducing labor costs, and the risk of ignition of gasoline and air trapped in the refueling area due to spark generation by static electricity charged to the body of the customer cannot be denied. In view of the above, the present applicant has proposed in patent document 1 a fueling device including a static electricity removing panel which is touched by a customer before fueling operation to remove static electricity charged to the body of the customer.

Disclosure of Invention
Problems to be solved by the invention
The invention described in patent document 1 is effective in that static electricity charged to the body of the customer can be discharged while the static electricity discharge panel is touched by the hand, but there is a possibility that static electricity is also charged to the body of the customer during the operation of the fuel gun after the hand is separated from the static electricity discharge panel, and therefore there is room for improvement.
Accordingly, an object of the present invention is to provide a safe fuel gun capable of reliably removing static electricity generated during a refueling operation, that is, during operation of the fuel gun.
Means for solving the problems
In order to achieve the above object, the present invention provides a fuel gun comprising: a main valve that opens by operating an opening valve lever to allow the fuel oil to flow therethrough; an automatic valve closing mechanism for releasing the engagement of the main valve and the open valve lever to stop the refueling when the liquid level in the tank to be refueled is sealed; a main body having the main valve and the automatic valve closing mechanism; a grasping portion formed of a conductive metal and grasped together with the valve opening lever when the valve opening lever is operated; a fuel hose connected to the grip portion and configured to supply fuel oil to the main body; a discharge pipe for discharging the fuel oil passing through the main valve; a ground wire which is arranged on the refueling hose and is connected with the gripping part; and a conductive cover covering the grip portion.
According to the present invention, since the grip portion and the cover covering the grip portion are made of a conductive material and the ground is connected to the grip portion, static electricity charged to an operator can be removed via the grip portion in an oiling operation, and the oiling operation can be performed safely.
In the fuel gun described above, the conductive cap is fixed to the end portion of the grip portion on the fuel hose side or the end portion of the grip portion on the main body side, whereby the conductive cap can be prevented from coming off the grip portion. Further, by fixing the conductive cover to the end portion of the grip portion on the refueling hose side and the end portion of the grip portion on the main body side, it is possible to prevent the conductive cover from rotating around the axis of the grip portion as well as from dropping off from the grip portion.
The conductive cover of the fuel gun may include a notch extending in the axial direction of the grip portion, and the conductive cover may be easily removed from the grip portion through the notch.
The fuel filler gun may include an oil receiver attached to a portion of the discharge pipe to which the main body is attached, the oil receiver receiving fuel oil that has dropped from the discharge pipe toward the main body, and a plurality of ribs that form valley portions for storing the dropped fuel oil being connected to a surface of the oil receiver on the discharge pipe side. This prevents fuel oil that has dropped along the discharge pipe from entering the main body.
In the oil receiving portion of the fuel filler gun, the ribs may be erected so as to form a contour concentric with the discharge pipe when the ribs are viewed from the discharge pipe side, and the outer ribs may be extended toward the discharge pipe side than the inner ribs. This allows the fuel oil that has dropped along the discharge pipe to be gradually stored from the center of the oil receiver to the peripheral portion, and thus prevents the fuel oil from entering the main body more effectively.
In the oil receiving portion of the fuel filler, a plurality of reinforcing members for connecting the plurality of ribs are provided, whereby deformation of the oil receiving portion can be prevented.
In the above fuel filler gun, the oil receiving portion may include: a sealing portion that surrounds the discharge pipe, attaches the oil receiving portion to the discharge pipe, and prevents intrusion of the fuel oil; and a shield portion that surrounds the discharge pipe, attaches the oil receiving portion to the discharge pipe together with the sealing portion, and prevents the oil receiving portion from being inclined with respect to the discharge pipe. This allows the oil receiving portion to be stably attached to the discharge pipe.
ADVANTAGEOUS EFFECTS OF INVENTION

Detailed Description
Next, embodiments of the present invention will be described in detail with reference to the drawings.
Fig. 1 shows an example of a fueling device including a fueling gun of the present invention, in which the fueling device 1 includes a plurality of fueling hoses 2 corresponding to a plurality of oil types and connected to built-in fueling pipes corresponding to the plurality of oil types, a fueling gun 11 provided at a distal end of each fueling hose 2, a display 3 for displaying a fueling amount and the like, a touch panel 4 for setting a fueling amount and the like, a card or the like inserted at the time of payment of a fueling fee and the like, a printer 6 for printing an invoice and the like, a static electricity removal pad 7 for removing static electricity charged by an operator before a fueling operation, and the like. The fueling hose 2, the display 3, the touch panel 4, the card reader 5, the printer 6, and the static electricity elimination pad 7 are components of the normal fueling device 1, and detailed description thereof will be omitted.
As shown in fig. 2, the fuel gun 11 is constituted by a main body 12, a discharge pipe 13, a grip portion 15 for operating an opening stem 14 projecting from the main body 12, and the like.
As shown in fig. 3, the main body 12 has a fuel oil flow path formed therein, and includes: a main valve 12a that opens the main valve 12a by operating an opening stem 14 (see fig. 2) to allow the fuel oil to flow; and an automatic valve closing mechanism 12b for releasing the engagement of the main valve 12a and the open valve lever 14 to stop the refueling when the liquid surface in the tank to be refueled is sealed. The discharge pipe 13 (see fig. 2) incorporates a liquid level detection pipe (not shown) extending from the automatic valve closing mechanism 12b and arranged so as to open on the discharge end side.
According to the above configuration, as shown in fig. 2 and 3, when the open valve lever 14 is grasped during the refueling operation and the main valve 12a is opened, the liquid level in the vehicle-mounted fuel tank rises, and when the liquid level detection pipe in the discharge pipe 13 detects fuel oil, it is determined that the vehicle-mounted fuel tank is full, and the automatic valve closing mechanism 12b closes the main valve 12a regardless of the state of the open valve lever 14, thereby forcibly ending the refueling operation.
Returning to fig. 2, the discharge pipe 13 is formed of, for example, an aluminum alloy, and includes: a reinforcing ring 13a built in the discharge end; an oil-proof member (oil receiving portion) 18 attached to an end portion on the side of the main body 12; and an anchor spring (anchor spring) 19 having one end fixed to the vicinity of the oil-proof member 18 and the other end extending toward the discharge end side. In fig. 3, the oil-proof member 18 is not shown.
The reinforcing ring 13a is provided to avoid the discharge end of the discharge pipe 13 being deformed to prevent the fuel from being supplied when the fuel filler worker drops the fuel filler gun 11 by mistake. The oil-repellent member 18 will be described later. The anchor spring 19 is provided for the following reasons: when the discharge pipe 13 is inserted into the vehicle-mounted tank, the end portion of the anchor spring 19 on the reinforcing ring 13a side abuts against the vehicle-mounted tank, and the oil-proof member 18 is prevented from colliding with the vehicle-mounted tank and being damaged.
The oil-proof member 18 is provided to prevent the fuel oil attached to the discharge pipe 13 after refueling from intruding into the main body 12 through the discharge pipe 13 when the fuel gun 11 is tilted so that the discharge pipe 13 faces upward.
As shown in fig. 4 and 5, the oil-proof member 18 is formed of a cylindrical portion 18a and an extending portion 18b extending in the radial direction from one end of the cylindrical portion 18a, and a seal portion 18c and a shield portion 18d covering the outer periphery of the discharge pipe 13 are provided on the inner side of the cylindrical portion 18a in two stages. The extension portion 18b is provided with ribs 18e (18e 1-18 e3) and a reinforcing member 18f for reinforcing the extension portion 18b to prevent deformation.
In the cylindrical portion 18a, a seal portion 18c is attached to the discharge pipe 13 so as not to have a gap with the discharge pipe 13 in order to prevent the fuel oil from entering. The protector 18d is provided for fixing the oil-proof member 18 to the discharge pipe 13 together with the seal portion 18c while preventing the inclination of the oil-proof member 18, and is inclined toward the discharge end of the discharge pipe 13 with a gap 18 g.
In the extended portion 18b, the ribs 18e are formed in three steps from the inside toward the outside, and are formed so as to gradually increase in height from the inner rib 18e1 toward the outer rib 18e 3. Valley portions 18h (18h 1-18 h3) where the fuel oil stays are formed between the ribs 18e, and the volume of the outer valley portion is larger than that of the inner valley portion.
The reinforcing members 18f are arranged to divide the rib 18e into four at 90 ° intervals. The number and arrangement of the reinforcing members 18f are merely examples, and it is preferable to keep the number of the reinforcing members 18f small while securing the minimum strength because the volume of the trough portions 18h2 and 18h3 is reduced by increasing the number of the reinforcing members 18 f.
The grip portion 15 shown in fig. 2 and 3 is made of a conductive metal, has a flow path connected to the flow path of the main body 12 formed therein, and has a connection portion 15a to which the refueling hose 2 is connected. The grip portion 15 is covered and protected by a conductive cover 16 made of conductive resin or the like.
Here, the filler hose 2 incorporates a lead wire 32 (see fig. 6) connected to a lamp circuit described later, and since the grip portion 15 and the conductive cover 16 are conductive as described above, static electricity charged by an operator gripping the conductive cover 16 of the grip portion 15 flows to the lamp circuit via the lead wire.
As shown in fig. 3, the conductive cover 16 is formed in accordance with the outer shapes of the main body 12 and the grip portion 15, and includes a notch 16a extending in the axial direction of the grip portion 15. By opening the conductive cover 16 through the notch 16a, the conductive cover 16 can be easily attached to and detached from the grip portion 15. Further, in the main body 12 and the grip portion 15, the portions where the both ends 16b and 16c of the conductive cover 16 are attached are not formed in a cylindrical shape or a columnar shape, and the outer diameters are not uniform, so that when the conductive cover 16 is fixed to the main body 12 and the grip portion 15 via the both ends 16b and 16c, the rotation of the conductive cover 16 around the axis can be prevented.
It is preferable to describe the date of manufacture as a standard for replacement (for example, about 3 years) on the surface of the conductive cover 16, and to cope with customers with high detergency, it is preferable to perform an antibacterial process on the surface of the conductive cover 16.
Further, a cover scarf 17 can be attached to the main body 12 side of the conductive cover 16 as shown in fig. 2. By using the cover scarf 17 to protect the main body 12 and using different colors for each oil type, the operator can easily confirm which fueling gun 11 corresponds to which oil. Note that fig. 3 omits the illustration of the scarf 17.
A guard 20 is provided to protect the opening stem 14, and the guard 20 is provided with a latch 21 for sliding one end of the opening stem 14 to enable the operation of opening the stem 14.
Next, a lamp circuit for removing static electricity charged to the body of a fueling operator who operates the fueling gun 11 shown in fig. 2 and the like and controlling the on/off of the neutralization confirmation lamp 8 shown in fig. 1 will be described with reference to fig. 6.
The lamp circuit 31 connects the grip portion 15 of the fuel gun 11 and the neutralization confirmation lamp 8 via a lead wire 32, and a comparator (comparator)33 and a holding circuit 34 for detecting static electricity of the fuel gun 11 are arranged between them, and the neutralization circuit 36 is connected in parallel between the fuel gun 11 and the holding circuit 34 via a lead wire 35, and a reset circuit 38 is connected to the holding circuit 34 via a lead wire 37.
The comparator 33 compares the voltage input from the input portion 33a with a reference voltage, and outputs a HIGH (HIGH) voltage when the input voltage is higher than the reference voltage, and outputs a LOW (LOW) voltage when the input voltage is lower than the reference voltage. When a high voltage is output from the output portion 33b, static electricity flows through the fueling gun 11, and the neutralization confirmation lamp 8 is turned on.
The holding circuit 34 is provided to hold the discharge confirmation lamp 8 on when the high voltage is not output from the output unit 33b after the high voltage is output from the output unit 33b of the comparator 33. This is because the static electricity flows through the comparator 33 at one instant, and even if the neutralization check lamp 8 is turned on during this period, the worker cannot visually check it.
The neutralization circuit 36 is a relay circuit and is provided to connect a contact point when a high voltage is output from the output unit 33b of the comparator 33 and discharge static electricity flowing through the fueling gun 11 to the ground. When a low voltage is output from the output unit 33b of the comparator 33, the contact is opened.
The reset circuit 38 is provided for the following reasons: when a predetermined time has elapsed since the holding circuit 34 started holding the circuit, the holding circuit 34 is released from holding and the neutralization confirmation lamp 8 is turned off, thereby preventing the neutralization confirmation lamp 8 from being continuously turned on.
According to the fuel gun 11 having the above configuration, even if the operator has static electricity after touching the static electricity removal pad 7 and removing the static electricity, the grip 15 and the conductive cover 16 have conductivity, and the lamp circuit 31 is connected to the grip 15, so that the static electricity input from the conductive cover 16 can be removed via the grip 15, the lead wire 32, and the static electricity removal circuit 36. Further, even when the operator forgets to touch the static electricity removal pad 7, the refueling operation can be safely performed.
Further, by setting the condition that the fueling mechanism of the fueling device 1 can supply fuel to both the ON signal of the gun switch (not shown) generated when the fueling gun 11 is removed from the gun mount (not shown) and the signal indicating that the contact point is not connected from the static elimination circuit 36, that is, that static electricity does not flow, as input, the fuel is not supplied if the operator is not in an uncharged state after the operator has left his or her hands away from the static electricity elimination pad 7, and therefore, it is safe.
Further, even if the fuel gun 11 is tilted so that the discharge pipe 13 is directed upward after refueling is completed until the worker pulls out the discharge pipe 13 from the in-vehicle tank and returns the fuel gun 11 to the fuel gun mount, the fuel oil adhering to the discharge pipe 13 can be stored in the valley portion 18h by the oil-proof member 18, and therefore, the fuel oil can be prevented from dropping through the discharge pipe 13 toward the main body 12. Further, since the oil-proof member 18 has a small diameter, the inside of the filler opening of the vehicle-mounted fuel tank can be seen during refueling, and refueling can be performed with ease without causing fuel to spill from the filler opening.
Next, another embodiment of the fuel gun according to the present invention will be described with reference to fig. 7. The fueling gun 41 includes a body 42, a grip portion 43, and a conductive cover 44, which are obtained by changing the shapes of the body 12, the grip portion 15, and the conductive cover 16 of the fueling gun 11 shown in fig. 2, and other components are the same as those of the fueling gun 11.
The conductive cover 44 of the present embodiment is not attached to the main body 42 but only to the grip portion 43, and similarly to the conductive cover 16, the notch 44a is provided to extend in the axial direction of the grip portion 43, so that the conductive cover can be easily attached to and detached from the grip portion 43. Further, since the connection portion side (right side of the paper surface) of the grip portion 43 is not formed in a cylindrical shape and has a non-uniform outer diameter, the conductive cover 44 is fixed to the grip portion 43 at the end portion 44b, and can be prevented from rotating around the axis of the grip portion 43.
In the fuel gun 11 of fig. 1, the hood scarf 17 is attached to the main body 12 side of the conductive hood 16, but in the present embodiment, the conductive hood 44 is not attached to the main body 42, and therefore the hood scarf can be directly attached to the main body 42.
The shapes and connection structures of the respective constituent elements described in the above embodiments are merely examples, and various modifications can be made without departing from the scope of the present invention.
