  FIG. 1 shows an overall configuration of a liquid injection device 1 according to an embodiment of the present invention. As shown in FIG. 1, the liquid injection device 1 is a device for supplying kerosene from a liquid injection port H that appears when a lid C of a tank T such as a kerosene tank (or kerosene cartridge) of an oil stove is removed. Kerosene is an example, and other liquids such as water and alcohol may be used instead of kerosene.

  As shown in FIG. 1, the liquid injection device 1 includes a liquid supply tank 2, a liquid discharge tool 3, and a pedestal portion 4. The liquid supply tank 2 is an 18 liter plastic tank used when supplying kerosene to a household stove, for example. However, an oil tank having a relatively large capacity, such as several tens of liters or several hundred liters, or other tanks may be used. A liquid supply port 5 with a lid for injecting liquid into the liquid supply tank 2 and a handle 6 for carrying the liquid supply tank 2 are provided at the upper part of the liquid supply tank 2. A connection portion 7 of the liquid discharge tool 3 is provided at the lower portion of the liquid supply tank 2, and a connection ring 8 of the liquid discharge portion 3 is screwed. The connecting portion 7 is the same as the state where the lid of the supply port 5 with the lid is removed, and the supply port 5 side may be used as the connecting portion 7.

  The liquid discharger 3 has a cylindrical connection ring 8 screwed into the connection part 7 of the liquid supply tank 2, a cylindrical main body part 9 in which a liquid flow path is formed, and a slide nozzle structure to be described later. When liquid is used, the protruding liquid injection hole D is inserted into the tank T and has a liquid injection part 10 for liquid injection, and an open / close lever 11 for opening and closing the liquid flow path.

  The pedestal 4 can adjust the installation height of the liquid supply tank 2 while the liquid supply tank 2 is placed thereon. For example, the liquid injection unit 10 of the liquid ejection tool 3 has a slide nozzle structure described later, and a tank T is installed below the liquid injection unit 10 during liquid injection. Accordingly, a certain distance is required between the lower part of the liquid ejection tool 3 and the floor surface on which the pedestal part 4 is placed. Further, the interval varies depending on the height of the fuel filler opening H of the tank T. Therefore, it is preferable that the pedestal portion 4 has a strength capable of supporting the weight of the liquid supply tank 2 and can freely change the height of the pedestal. The shape of the pedestal portion 4 shown in FIG. 1 schematically represents the pedestal, and the shape and configuration of the pedestal portion 4 may be any. For example, a floor with a step may be used as the pedestal.

  Next, the liquid ejection tool 3 will be described in detail with reference to FIG. As described above, the liquid ejection tool 3 includes the connection ring 8, the main body portion 9, the liquid injection portion 10, and the open / close lever 11 as an appearance configuration.

  A cylindrical packing member 13 made of rubber or silicon is placed inside the circular opening 12 of the connection ring 8. A cylindrical flange portion 14 that is an end portion of the main body portion 9 is sandwiched between the packing member 13 and the inside of the opening portion 12. Further, a screw 15 is cut in the inner peripheral portion of the connection ring 8. The screw 15 is formed so as to be screwed with a screw cut in the outer peripheral portion of the connection portion 7 of the liquid supply tank 2 shown in FIG.

  The main body portion 9 has a circular supply hole 16 through which the liquid is supplied from the liquid supply tank 2 to the inner peripheral portion of the flange portion 14. The main body 9 is provided with a cylindrical liquid injection connecting portion 17 extending downward in FIG. The liquid injection connecting part 17 has a discharge hole 17 a connected to the liquid injection part 10. Further, the main body 9 has a liquid flow path 18 between the supply hole 16 connected to the liquid supply tank 2 and the discharge hole 17 a connected to the liquid injection part 10. A cylindrical opening / closing member 19 for opening and closing the liquid channel 18 is installed in the liquid channel 18. The opening / closing member 19 has a conical shape in which the left end in FIG. 2 is formed thicker than the other portions, and constitutes an opening / closing valve 20. The on-off valve 20 comes into contact with the conical inner wall of the main body 9 and can stop the liquid flowing out from the supply hole 16 of the main body 9. A circular groove 19a is formed in the opening / closing member 19 where the on / off valve 20 comes into contact with the inner wall of the main body 9, and an O-ring 19b is fitted in the groove 19a. The liquid-tightness when closing 18 is improved. The end of the opening / closing member 19 opposite to the opening / closing valve 20 is inserted into a holding hole 22 of a cylindrical tubular portion 21 provided inside the main body 9 and is held by the tubular portion 21. ing.

  Two O-rings 19 c and 19 d are provided between the inner wall of the tubular portion 21 and the outer wall of the opening / closing member 19. Thereby, the liquid tightness between the inner periphery of the tubular portion 21 and the outer periphery of the opening / closing member 19 is ensured, and the liquid does not flow into the space on the opening / closing lever 11 side.

  The end of the opening / closing member 19 on the side inserted into the holding hole 22 further protrudes from the tubular portion 21 and reaches the position of the opening / closing lever 11. Note that a contact member 24 having a circular shape and an engagement portion with the opening / closing member 19 is attached to the contact portion with the opening / closing lever 11 at the tip of the opening / closing member 19 on the opening / closing lever 11 side. A coil spring 25 is provided between the contact member 24 and the tubular portion 21. Here, the contact member 24 is in contact with the end of the coil spring 25 opposite to the end in contact with the tubular portion 21, and plays a role of transmitting the force from the coil spring 25 to the opening / closing member 19. If the contact member 24 is made of self-lubricating resin or the like, the movement of the opening / closing lever 11 can be made smooth, and wear of the contact portion of the opening / closing lever 11 with the contact member 24 can be reduced. 3 lifespan can be extended.

  The open / close lever 11 swings about the shaft portion 26. By rotating the opening / closing lever 11 in the right direction in FIG. 2, a part of the opening / closing lever 11 pushes the contact member 24, so that the opening / closing member 19 moves to the left in FIG. As a result, a gap is generated between the on-off valve 20 and the main body 9. Thereby, the liquid in the liquid supply tank 2 flows into the liquid flow path 18 and flows into the liquid injection part 10 from the discharge hole 17. When the force applied to the opening / closing lever 11 is removed, the opening / closing member 19 moves to the right in FIG. As a result, there is no gap between the on-off valve 20 and the main body 9 and the liquid discharge stops.

  The liquid injection part 10 is attached to the liquid connection part 17 of the main body part 9 by a liquid injection part connection ring 27. That is, a screw 28 is cut on the outer periphery of the discharge hole 17 a, and a screw 29 is also cut on the inner periphery of the liquid injection part connecting ring 27. The liquid injection part 10 is attached to the main body part 9 when the screw 28 and the screw 29 are screwed together. Furthermore, a ring-shaped packing member 30 made of rubber or silicon is provided at the lower edge of the discharge hole 17a. The packing member 30 ensures liquid tightness between the discharge hole 17a and the outer cylindrical portion 32.

  The liquid injection part 10 includes a cylindrical inner cylindrical part 31, a cylindrical outer cylindrical part 32, a ring-shaped liquid absorbing part 33, and a liquid absorbing member holding part 34 having a small diameter and a large diameter cylindrical part. Configured. The state shown in FIGS. 2 and 3 is a state in which the inner cylindrical portion 31 is housed most inwardly.

  The outer cylindrical portion 32 includes the inner cylindrical portion 31 inside. The inner cylindrical portion 31 has a slide nozzle structure that can move inside the outer cylindrical portion 32 in the direction of the central axis N and in the opposite direction to the main body 9 and in the opposite direction. Further, when the inner cylindrical portion 31 moves inside the outer cylindrical portion 32, it moves while being in contact with the inner periphery of the through hole P provided at the center of the liquid absorbing portion 33. The liquid absorption part 33 is formed of a material having a high ability to absorb a liquid such as felt. The liquid absorbing part 33 is preferably felt in view of its good absorbency and elasticity.

  The liquid absorbing member holding part 34 holds the liquid absorbing part 33 inside, and a concave part 35 provided in the outer cylindrical part 32 and a convex part 36 provided in the liquid absorbing member holding part 34 are fitted. Thereby, the liquid absorbing member holding portion 34 is locked to the end portion of the outer cylindrical portion 32. The locking relationship may be reversed, that is, the outer cylindrical portion 32 may be provided with a convex portion and the liquid absorbing member holding portion 34 may be provided with a concave portion.

  In addition, as shown in FIG. 3, the liquid injection part 10 is provided with a gripping part 37 on the inner cylindrical part 31. The grip portion 37 is a portion that the user grips with a finger or the like in order to manually slide and move the inner cylindrical portion 31. The outer cylindrical portion 32 is provided with a notch 38 so as not to hinder the movement of the gripping portion 37. The gripping part 37 penetrates the notch part 38 and protrudes outward. The cutout portion 38 continues to the cut portion 39 of the outer cylindrical portion 32. That is, the notch 38 continues to the lower end in FIGS. 2 and 3 of the outer cylindrical portion 32 and is slit. As shown in FIG. 2, the outer peripheral portion of the outer cylindrical portion 32 provided with the cut portion 39 has a convex portion 36 of the liquid absorbing member holding portion 34 with respect to the concave portion 35 of the outer cylindrical portion 32. Since it fits, it can prevent that the cut part 39 opens outside. Further, in order to prevent the diameter of the outer cylindrical portion 32 from being reduced due to the presence of the cutout portion 38, an engaging portion described later is inserted into the liquid absorption member holding portion 34 from the cutout portion 39 to the cutout portion 38. 43 is provided. As described above, the liquid absorbing member holding portion 34 prevents the split portion 39 from opening outward and does not squeeze inward, so that the inner wall of the outer cylindrical portion 32 and the outer wall of the inner cylindrical portion 31 There is no gap between them, and the slide can be made smooth.

  Further, as shown in FIG. 3, the liquid absorbing member holding portion 34 has a number of slit-like gaps 40. When the liquid absorbing member holding part 34 holds the liquid absorbing part 33, the liquid absorbing part holding part 34 can be held by the gap 40 so that the liquid absorbing part 33 sufficiently contacts the air. According to this, when the liquid absorption part 33 absorbs the liquid, it is possible to prevent the liquid from spontaneously evaporating into the air. The liquid absorbing member holding part 34 has a plurality of protrusions 41 that form the gaps 40. As shown in FIG. 2, the tip of the projecting portion 41 is a claw portion 42 that bends inward. The claw portion 42 prevents the liquid absorbing portion 33 from being detached. On the other hand, the protrusion 41 has elasticity, and by pulling the protrusion 41 outward, the claw part 42 is separated from the liquid absorption part 33. Therefore, the old liquid absorption part 33 is removed and replaced with a new liquid absorption part 33. It is easy. According to this, the liquid absorbing member holding part 34 reliably holds the liquid absorbing part 33 in the normal state, but when the liquid absorbing part 33 is replaced, the liquid absorbing part 33 can be easily detached.

  Further, as shown in FIG. 4, the inner cylindrical portion 31 protrudes from the outer cylindrical portion 32 by the user holding the grip portion 37 with a finger and moving the grip portion 37 below the notch portion 38. The gripping part 37 collides with the upper end of the liquid absorbing member holding part 34 in FIG. 4, and further downward movement is prevented. The state in FIG. 4 is a state in which the inner cylindrical portion 31 protrudes most from the outer cylindrical portion 32.

  In the example shown in FIG. 5, the convex portion 36 of the liquid absorbing member holding portion 34 is configured by a large number of convex portions 36. In addition, the convex portion 36 may be constituted by one annular convex portion. In this embodiment, the liquid absorbing member holding part 34 is provided with an engaging part 43 that enters the notch part 38 from the cut part 39. The engaging portion 43 prevents the outer cylindrical portion 32 from becoming smaller in diameter, makes the size of the cutout portion 38 in the radial direction constant from the upper side to the lower side, smoothes the movement of the gripping portion 37, and The gap between the cylindrical portion 31 and the outer cylindrical portion 32 is eliminated, and the inner cylindrical portion 31 is slid smoothly.

  As described above, the liquid ejection tool 3 according to the embodiment of the present invention is connected to the liquid supply tank 2 having a large capacity placed on the pedestal portion 2 and subdivides the liquid into the tank T having a small capacity. Used for.

  When liquid is injected from the liquid discharger 3 to the tank T, the liquid absorbing member holding part 34 of the liquid injection part 3 is positioned directly above the liquid supply port H that appears when the cap C is removed from the tank T. Place tank T on

  Next, when the user pushes down the grip portion 37 with a finger or the like, the tip end portion of the inner cylindrical portion 31 is inserted into the tank T from the liquid supply port H. In this state, when the user rotates the open / close lever 11 with the finger or the like in the right direction in FIGS. 1 and 2 to open the open / close valve 20, the liquid in the liquid supply tank 2 passes through the liquid ejection tool 3. It flows into the tank T.

  Eventually, when a predetermined amount of liquid is supplied into the tank T and it is desired to end the supply, the user releases the opening / closing lever 11 or operates the opening / closing lever 11 with the finger or the like in the left direction in FIGS. Then, the on-off valve 20 is closed, and the outflow of liquid from the liquid ejection tool 3 stops.

  Next, when the user pushes up the grip portion 37 with a finger or the like, the inner cylindrical portion 31 that was in the state of FIG. 4 returns to the state of FIG. At this time, the outer periphery of the inner cylindrical portion 31 moves while touching the inner periphery of the through hole P of the liquid absorbing portion 33. Thereby, the liquid absorption part 33 absorbs the liquid adhering to the outer periphery of the inner cylindrical part 31. Accordingly, dripping from the outer periphery of the inner cylindrical portion 31 can be completely prevented.

  Also, during these operations, the user's finger never touches the liquid. Therefore, when the liquid is supplied to the tank T, it is possible to prevent the user's hand and fingers from getting dirty at all. As shown in FIG. 2 and FIG. 3, when the gripping portion 37 is pushed up most upward, the lower end of the inner cylindrical portion 31 is positioned above the lower end of the liquid absorbing portion 33. That is, the lower end side of the liquid absorbing part 33 protrudes slightly toward the inner cylindrical part 31 side, and comes into contact with the lower end surface of the inner cylindrical part 31, and the lower end of the inner cylindrical part 31 is the liquid absorbing part. 33 is completely stored. For this reason, the possibility that the liquid remaining on the lower end surface and the inner side surface of the inner cylindrical portion 31 can be absorbed is increased, and the effect of preventing dripping is further increased.

  The liquid absorbing part 33 can be formed of felt or paper. Further, the liquid absorbing part 33 is exposed to air by a large surface area through the numerous gaps 40 of the liquid absorbing member holding part 34. Thereby, the liquid absorbed by the liquid absorption part 33 evaporates from the liquid absorption part 33 into the air in a short time. Therefore, the next time when liquid is sucked from the liquid ejection tool 3, the liquid sucking portion 33 is returned to the dry state, and the liquid sucking portion 33 is again well attached to the outer periphery of the inner cylindrical portion 31 and the like. Liquid can be absorbed. Moreover, the liquid absorption part 33 is easily exchangeable. The inner cylindrical portion 31 can move from the state of FIGS. 2 and 3 to the state of FIG. 4 and vice versa, but the liquid injection device 1 such as the size of the tank T and the size of the pedestal portion 4 can be used. The movement end position of the inner cylindrical portion 31 (= the position in the tank T) may be appropriately changed depending on the configuration and usage pattern. Similarly, after the liquid is discharged, the return position of the inner cylindrical portion 31 may be an intermediate position instead of the position of FIGS. 2 and 3, but from the viewpoint of preventing dripping, the position of FIGS. Most preferred.

(Other embodiments)
The embodiment of the present invention can be variously modified without departing from the gist thereof. For example, in the liquid ejection tool 3A shown in FIG. 6, the liquid injection part 10A is also integrally formed with the main body part 9A. According to this, compared with the liquid discharge tool 3, the number of parts can be reduced.

  Moreover, as shown in FIG. 7, it is good also as the liquid injection apparatus 1A which has a large sized liquid supply tank 2A. The liquid injection device 1 </ b> A includes a large liquid supply tank 2 </ b> A, a liquid discharge tool 3, and a pedestal portion 4. The liquid supply tank 2A is a tank having a relatively large capacity such as several tens of liters or several hundreds of liters. A liquid supply port 51 with a lid for injecting liquid into the liquid supply tank 2A and a fuel gauge 52 for displaying the remaining amount of liquid in the liquid supply tank 2A are provided at the top of the liquid supply tank 2A. It has been. Below the liquid supply tank 2A, a connection portion 7 of the liquid discharge tool 3 is provided, and a connection ring 8 of the liquid discharge portion 3 is screwed.

  The main material of the liquid ejection tools 3 and 3A is assumed to be a synthetic resin except for the packing members 13 and 30, the coil spring 25, the liquid absorbing portion 33, and the like. Good. The liquid injection devices 1 and 1 </ b> A may include the pedestal portion 4, but may not have the pedestal portion 4. Furthermore, although the number of the gripping portions 37 and the cutout portions 38 is one, it may be two or more.

  In the above-described embodiment, the opening / closing lever 11 presses the opening / closing member 19 to open / close the opening / closing valve 20. However, instead of the opening / closing lever 11 and the opening / closing member 19, the drain channel is turned to turn the liquid channel The structure which opens and closes may be sufficient. In addition, the configuration of the liquid channel may be variously changed. Further, in order to prevent the hands from getting dirty, the gripping portion 37 and the cutout portion 38 are provided. However, if the hand may be dirty or if the inner cylindrical portion 31 is configured to be slidable by another method, the gripping portion 37 and the notch 38 may be omitted.

  In the above-described embodiment, the length of the inner cylindrical portion 31 has been described as being shorter than the length of the outer cylindrical portion 32. As a result, the lower end of the inner cylindrical portion 31 is completely accommodated in the liquid absorbing portion 33, which is preferable because no dripping occurs. However, when some dripping may be allowed, the length of the inner cylindrical portion 31 may be longer than the length of the outer cylindrical portion 32. In such a case, the lower end of the inner cylindrical portion 31 when fully stored may protrude from the lower end of the liquid absorbing portion 33.

  In addition, the liquid absorbing member holding portion 34 has been described as having a large number of gaps 40 and protrusions 41, but may be a cylinder without these gaps 40 and protrusions 41.

  As shown in FIG. 8, the liquid injection device 1 </ b> B has a configuration in which the pedestal portion 60 is supported by the support base 62 by the support shaft 61 so that the liquid supply tank 2 can swing. The swing is performed between the state in which the supply hole to which the liquid ejection tool 3 is attached faces upward and the state in which the supply hole faces sideways.

  The base portion 60 is provided with notches 63 and 64. The notches 63 and 64 are adapted to engage with the stopper 65, respectively. The stopper 65 is always pushed upward by the spring (not shown). A knob portion 67 is attached to the stopper 65, and the user can release the fitting between the stopper 65 and the notch portion 63 or 64 by pressing the knob portion 67 below the groove portion 66.

  According to this, when not refueling, the supply hole in the portion of the liquid supply tank 2 to which the liquid discharge tool 3 is attached can be made to face upward as shown in FIG. Thereby, for example, even if the liquid discharge tool 3 is erroneously opened even after the end of refueling, the liquid in the liquid supply tank 2 can be prevented from leaking.

  During refueling, the pedestal 60 is swung so that the notch 63 of the pedestal 60 is engaged with the stopper 65. Thereby, during refueling, the supply hole in the portion of the liquid supply tank 2 to which the liquid discharge tool 3 is attached can be made to face sideways.
