  A liquid injection device 1 shown in FIG. 1 is an apparatus 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 that is a liquid supply source, a liquid ejection tool 3 according to an embodiment of the present invention, 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. In the upper part of the liquid supply tank 2, a supply port 5 a with a lid 5 for injecting liquid into the liquid supply tank 2 and a handle 6 for carrying the liquid supply tank 2 are provided. A connection portion 7 is provided at the lower portion of the liquid supply tank 2, and the connection ring 8 of the liquid discharge tool 3 is screwed into the connection portion 7. Since the shape of the connection portion 7 is the same as the shape of the supply port 5a with the lid 5 removed, the supply port 5a side may be used as the connection portion 7.

  The liquid discharger 3 includes a cylindrical connection ring 8 with an inward flange that is screwed into the connection portion 7 of the liquid supply tank 2, a cylindrical main body portion 9 that forms a liquid flow path 18, and a slide nozzle structure that will be described later. And has a liquid injection part 10 for injecting the liquid by inserting the protruding liquid injection hole D into the tank T and an opening / closing lever 11 for opening and closing the liquid flow path 18 as external components. .

  The pedestal portion 4 can place the liquid supply tank 2 on this and adjust the placement height of the liquid supply tank 2. 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 is mounted inside the inward flange portion 12 that forms the circular opening of the connection ring 8. Further, an outward flange portion 14 serving as an end portion of the main body portion 9 is sandwiched between the packing member 13 and the inside of the inward flange 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 9 has a circular supply hole 16 through which liquid is supplied from the liquid supply tank 2 to the inner peripheral portion of the outward flange portion 14. The main body 9 is provided with a cylindrical connecting portion 17 extending downward in FIG. 2, and the liquid injection portion 10 is connected to the connecting portion 17. The connection 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 valve body 19 serving as an opening / closing member for opening / closing the liquid passage 18 is installed in the liquid passage 18. The valve body 19 has a conical valve portion 19b having a maximum tip diameter at one end portion (left end portion in FIG. 2) of the horizontally long cylindrical portion 19a. The valve portion 19b is urged to the right in FIG. 2 by a coil spring 25 to be described later, contacts the valve seat 9a formed by the conical inner wall of the main body portion 9, and flows into the supply hole 16 of the main body portion 9. Can stop the incoming liquid. A circular groove 19c is formed in a portion where the valve portion 19b of the valve body 19 is in contact with the valve seat 9a of the main body portion 9, and an O-ring 20 is fitted into the groove 19c, so that the valve portion 19b is in a liquid flow. The liquid-tightness when closing the path 18 is enhanced. Further, the cylindrical portion 19 a of the valve body 19 is inscribed in a cylindrical portion 21 provided inside the main body portion 9 so as to be slidable in the axial direction.

  Two front and rear O-rings 22 are provided between the inner wall of the cylindrical portion 21 and the outer wall of the columnar portion 19 a of the valve body 19. Thereby, the liquid-tightness between the inner periphery of the cylinder part 21 and the outer periphery of the valve body 19 is ensured, and the liquid does not flow into the chamber 23 on the opening / closing lever 11 side.

  The columnar portion 19 a of the valve body 19 extends from the tubular portion 21 to the chamber 23 and reaches the position of the opening / closing lever 11. In addition, the contact member 24 which is circular and has a coupling | bond part with the cylinder part 19a is adhering to the front-end | tip part by the side of the opening / closing lever 11 of the cylinder part 19a. A coil spring 25 is provided between the contact member 24 and the cylindrical portion 21. The contact member 24 serves as a member that contacts the opening / closing lever 11 and a member that stops one end of the coil spring 25. Here, the contact member 24 plays a role of transmitting the force from the coil spring 25 to the valve body 19.

  The opening / closing lever 11 has a base portion 11b having a cam surface 11a on one side at one end, and the base portion 11b is inside the end portion of the main body portion 9 opposite to the valve seat 9a, that is, behind the contact member 24 of the chamber 23. It is provided so that it can be rotated about the shaft part 26. 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 on the contact surface between the opening / closing lever 11 and the contact member 24 can be reduced. 3 lifespan can be extended. When the opening / closing lever 11 is rotated in the clockwise direction in FIG. 2, the cam surface 11a of the opening / closing lever 11 pushes the contact member 24, so that the valve body 19 moves to the left in FIG. As a result, a gap is generated between the valve portion 19b and the valve seat 9a. As a result, 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 17a. When the force applied to the opening / closing lever 11 is removed, the valve element 19 moves to the right in FIG. 2 by the extension force of the coil spring 25, and the opening / closing lever 11 returns to the original position. As a result, there is no gap between the valve portion 19b and the valve seat 9a, and the flow of liquid into the liquid flow path 18 stops.

  The liquid injection part 10 is attached to a connection part 17 projecting from the lower surface 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 by screwing the screw 28 and the screw 29 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 described later.

  The liquid injection part 10 includes a cylindrical inner cylindrical part (hereinafter referred to as “inner cylinder”) 31, a cylindrical outer cylindrical part (hereinafter referred to as “outer cylinder”) 32, a ring-shaped liquid absorbing part. 33, and a liquid-absorbing part holding member 34 formed by connecting a small diameter part and a large diameter cylindrical part in the axial direction. The inner cylinder 31 corresponds to a first cylindrical portion described in the claims, and the outer cylinder 32 corresponds to a second cylindrical portion described in the claims. 2 and 3 show a state in which the inner cylinder 31 is housed most inwardly with respect to the outer cylinder 32. FIG.

  The outer cylinder 32 includes the inner cylinder 31 inside. The inner cylinder 31 constitutes a slide nozzle structure that can move inside the outer cylinder 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 cylinder 31 moves inside the outer cylinder 32, it moves while in contact with the inner periphery of the through hole P provided at the center of the liquid absorbing member 33. The liquid absorbing member 33 is formed of a material having a high ability to absorb liquid such as felt. The liquid absorbing member 33 is preferably felt in view of its good absorbency and elasticity.

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

  As shown in FIG. 3, a gripping member 37 is provided on the inner cylinder 31 of the liquid injection unit 10. The gripping member 37 is to be gripped by a user with a finger or the like in order to manually slide and move the inner cylinder 31. The outer cylinder 32 is provided with a notch 38 that allows the gripping member 37 to move in the vertical direction, and the gripping member 37 protrudes outward from the notch 38. The cutout portion 38 continues to the cut portion 39 of the outer cylinder 32. That is, the notch 38 continues to the lower end of the outer cylinder 32 in FIG. 2 and FIG. In addition, as shown in FIG. 2, the convex portion 36 of the liquid absorbing portion holding member 34 is fitted to the concave portion 35 of the outer cylinder 32 on the outer peripheral portion of the outer cylinder 32 provided with the cut portion 39. Therefore, it is possible to prevent the cut portion 39 from opening outward. Further, in order to prevent the diameter of the outer cylinder 32 from becoming narrow due to the presence of the notch portion 38, an engaging portion 43 to be described later inserted into the notch portion 38 from the cut portion 39 is provided in the liquid absorbing portion holding member 34. Is provided. As described above, the liquid absorbing portion holding member 34 prevents the split portion 39 from opening outward and does not squeeze inward, so that there is no gap between the inner wall of the outer cylinder 32 and the outer wall of the inner cylinder 31. There is no gap, and the inner cylinder 31 can be smoothly slid in the axial direction.

  Further, as shown in FIG. 3, the liquid absorbing portion holding member 34 has a number of slit-like gaps 40. Due to the gap 40, the liquid-absorbing part holding member 34 can hold the liquid-absorbing part 33 so that the liquid-absorbing member 33 is sufficiently in contact with air when the liquid-absorbing part 33 is held. According to this, when the liquid absorbing member 33 absorbs the liquid, it can be promoted that the liquid naturally evaporates in the air. In addition, the liquid absorption part holding member 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 holds the liquid absorbing member 33 so as not to come off. On the other hand, the protruding portion 41 has elasticity, and the claw portion 42 is separated from the liquid absorbing member 33 by pulling the protruding portion 41 outward. Therefore, the old liquid absorbing portion 33 is removed and replaced with a new liquid absorbing member 33. It is easy. According to this, the liquid absorption part holding member 34 reliably holds the liquid absorption member 33 at the normal time, but when the liquid absorption member 33 is replaced, the liquid absorption member 33 can be easily attached and detached.

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

  In the example shown in FIG. 5, the convex portion 36 of the liquid absorbing portion holding member 34 is constituted 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 portion holding member 34 is provided with an engaging portion 43 that enters the notched portion 38 from the cut portion 39. The engaging portion 43 prevents the diameter of the outer cylinder 32 from becoming smaller, makes the size of the notch portion 38 in the radial direction constant from the upper side to the lower side, smoothes the movement of the gripping member 37, and The gap between the outer cylinder 32 is eliminated and the inner cylinder 31 slides 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 suction member holding member 34 of the liquid injection member 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 holding member 37 downward with a finger or the like, the distal end portion of the inner cylinder 31 is inserted into the tank T from the liquid supply port H. In this state, when the user rotates the opening / closing lever 11 with a finger or the like in the right direction in FIGS. 1 and 2 to open the valve body 19, 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 valve body 19 is closed, and the outflow of the liquid from the liquid discharge tool 3 stops.

  Next, when the user pushes up the gripping member 37 with a finger or the like, the inner cylinder 31 in the state of FIG. 4 returns to the state of FIG. At this time, the outer periphery of the inner cylinder 31 moves while touching the inner periphery of the through hole P of the liquid absorbing member 33. As a result, the liquid absorbing member 33 absorbs the liquid adhering to the outer periphery of the inner cylinder 31. Therefore, dripping from the outer periphery of the inner cylinder 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 FIGS. 2 and 3, when the gripping member 37 is pushed up most upward, the lower end of the inner cylinder 31 is positioned above the lower end of the liquid absorbing portion 33. That is, the lower end side of the liquid absorbing member 33 protrudes slightly toward the inner cylinder 31 side and comes into contact with the lower end surface of the inner cylinder 31, and the lower end of the inner cylinder 31 is completely stored in the liquid absorbing member 33. The For this reason, there is a high possibility that the liquid remaining on the lower end surface and the inner side surface of the inner cylinder 31 can be absorbed, and the effect of preventing dripping becomes higher.

  The liquid absorbing member 33 can be formed of felt or paper. Further, the liquid absorbing member 33 comes into contact with air by a large surface area due to the numerous gaps 40 included in the liquid absorbing portion holding member 34. Thereby, the liquid absorbed by the liquid absorbing member 33 evaporates from the liquid absorbing member 33 into the air in a short time. Therefore, the next time when liquid is sucked from the liquid ejection tool 3, the liquid absorbing member 33 is returned to the dry state, and the liquid absorbing member 33 again returns the liquid adhering to the outer periphery of the inner cylinder 31 and the like. Can absorb liquid. Further, the liquid absorbing member 33 can be easily replaced. The inner cylinder 31 can move from the state shown in FIGS. 2 and 3 to the state shown in FIG. 4 and vice versa. However, the configuration of 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 cylinder 31 (= the position in the tank T) may be appropriately changed depending on the usage form. Similarly, after the liquid is discharged, the return position of the inner cylinder 31 may be an intermediate position instead of the positions shown in FIGS. 2 and 3, but the position shown in FIGS. preferable.

  The configuration of the liquid ejection tool 3 described above is the same as the liquid ejection tool proposed in the specification of Japanese Patent Application No. 2012-013419. In the liquid ejection tool 3 according to this embodiment, in addition to the above configuration, a ring-shaped seal portion 44 that performs a liquid sealing function with the outer cylinder 32 is provided on the outer periphery of the inner cylinder 31, for example, an O-ring. Yes. The seal portion 44 is provided at the upper end portion of the inner cylinder 31, and when the gripping member 37 is pushed downward to project the inner cylinder 31 downward from the liquid absorbing member 33, the seal portion 44 also remains in close contact with the outer periphery of the outer cylinder 32. Slide down. In this case, the amount of protrusion of the inner cylinder 31 from the outer cylinder 32 is regulated by the gripping member 37 coming into contact with the upper end of the liquid absorbing part holding member 34 closing the lower end of the through hole 38 of the outer cylinder 32. The amount is set so that the seal portion 44 is not exposed to the through hole 38. Thus, the liquid absorption part holding member 34 is a restricting part that restricts the downward movement of the inner cylinder 31. 3 shows a state where the seal portion 44 is at the uppermost position, and FIG. 4 shows a state where the seal portion 44 is at the lowermost position, and the seal portion 44 at the lowermost position is not exposed to the through hole 38. Thereby, the sealing function is ensured.

  As shown in FIG. 6, the seal portion 44 in FIG. 2 preferably has a structure (44A) formed by processing 44b with Teflon (registered trademark) on the outer periphery of a rubber ring 44a. . As a result, the friction coefficient of the seal portion 44 becomes small, that is, the frictional force between the ring 44a and the outer cylinder 32 becomes smaller, so that the inner cylinder 31 can move smoothly with respect to the outer cylinder 32. is there.

  Further, as the seal portion 44 in FIG. 2, as shown in FIG. 7, a structure (44 </ b> B) formed of a ring 44 c made of Teflon (registered trademark) resin having a “C” cross section is used. can do. The ring 44c may be mounted so that the cross-sectional shape is an inverted “C” shape in FIG.

  Further, as shown in FIG. 8, the groove 31a is formed on the outer periphery of the upper end portion of the inner cylinder 31, and the protrusion 31b having a triangular cross section that slightly protrudes from the outer periphery of the inner cylinder 31 is formed (44C). ) May be used as the seal portion 44. The seal structure 44C has an appropriate elasticity because it has a thin tip, and thus exhibits a sealing effect. If a protrusion 31c having substantially the same diameter as the protrusion 31b is provided on the outer periphery of the inner cylinder 31 at a position away from the protrusion 31b, the movement of the inner cylinder 31 is more stable than when only the protrusion 31b has no protrusion 31c. This is preferable because the property is increased.

  In a preferred embodiment of the present invention, a battery (not shown) is provided outside or inside the gripping member 37, and an ON / OFF switch (not shown) is provided on at least one of the gripping member 37 or the inner cylinder 31. It is preferable to provide an illumination member (not shown) connected to the battery, for example, an LED. When this illumination member is provided, when the tip of the protruding inner cylinder 31 is inserted into the tank T, the tip of the inner cylinder 31 or its periphery is brightened so that the tip of the inner cylinder 31 can be easily and reliably attached to the tank T. Can be inserted. The ON / OFF switch may be a piezoelectric switch or a toggle switch that is turned on by the force of a finger holding the holding member 37.

  Furthermore, in a preferred embodiment of the present invention, a detection member (not shown) for detecting that the inner cylinder 31 has contacted the liquid stored in the tank T, for example, a well-known liquid level sensor is connected to the lower end of the inner cylinder 3. In addition to being provided in the section, a notification means (not shown) for notifying when the detection member detects, for example, a light emitting element or a buzzer is provided. As a result, when supplying the liquid from the liquid discharger 3 to the tank T, the notification means operates when it is almost full, so that it is prevented from overflowing without knowing that it is full. This is also prevention of liquid leakage in a broad sense.

[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. 9, 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.

  In the example of FIG. 2, as a connection structure between the main body portion 9 and the liquid injection portion 10, a liquid injection portion connection ring 27 is screwed into the connection portion 17 of the main body portion 9, and the liquid injection portion connection ring 27 is used for injection. Although the structure which clamps the outward flange of the upper end part of the outer cylinder 32 of the liquid part 10 between the connection parts 17 is taken, like the liquid discharge tool 3B shown to FIG. 10, FIG. Two protrusions 17b projecting outward are provided at positions opposite to each other on the outer periphery of the lower end of the connecting portion 17, and an outer cylinder ring 32a is formed on the outer periphery of the upper end portion of the outer cylinder 32. The outer cylinder ring 32a is opposite to each other.

  In the above-described embodiment, the opening / closing lever 11 presses the valve body 19 to open and close the valve portion 20. However, instead of the opening / closing lever 11 and the valve body 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. In addition, the gripping member 37 and the cutout portion 38 are provided to prevent the hands from getting dirty. However, if the hand may be dirty or if the inner cylinder 31 is configured to be slidable by other methods, The notch 38 may be omitted.

  In the above-described embodiment, the length of the inner cylinder 31 has been described as being shorter than the length of the outer cylinder 32. As a result, the lower end of the inner cylinder 31 is completely accommodated in the liquid absorbing member 33, which is preferable because there is no dripping. However, in the case where some dripping may be allowed, the length of the inner cylinder 31 may be longer than the length of the outer cylinder 32. In such a case, the lower end of the inner cylinder 31 at the time of complete storage may protrude from the lower end of the liquid absorbing member 33. Moreover, although the liquid absorption part holding member 34 has been described as having a large number of gaps 40 and protrusions 41, the liquid absorption part holding member 34 may have a cylindrical shape without these gaps 40 and protrusions 41.

It may be made of metal. The synthetic resin forming the main body 9 and the liquid injection part 10 is preferably POM (polyoxymethylene) or nylon, considering its hardness (durability, accuracy), and considering both cost and hardness. POM is preferred. The seal portions 44 and 44c are preferably made of Viton (registered trademark), which is a fluorine rubber made by DuPont, USA, because the movement and sealability are good for a long period. Viton (registered trademark) having a hardness of 55 to 60, particularly a hardness of 55 is preferable.

  Further, in the above-described embodiment, the liquid absorbing part holding member 34 is a restricting part that restricts the downward movement of the inner cylinder 31, but other parts can be externally attached as restricting parts, or through holes The shape surrounding the through hole may be used as a restriction portion. Moreover, although the slit-shaped notch part 38 was shown as a through-hole, it is good also as a hole enclosed by the circumference | surroundings.

  In addition, the liquid injection device 1 may include the pedestal portion 4 but may not include the pedestal portion 4. Furthermore, although the number of the gripping members 37 and the notch portions 38 is one, two or more may be used. The liquid ejecting tools 3, 3A, 3B, 3C, and 3D are installed in the liquid supply tank 2, but may be installed in various home tanks such as a kerosene home tank having a storage amount of 200 liters or more. Further, the structure of the opening / closing lever 11 and its periphery and / or the valve body 19 may be applied to a liquid discharge tool for a water tank. Furthermore, the liquid ejection tools 3, 3A, 3B, 3C, 3D may be applied to the water tank. In the case of a water tank, the problem that the hands get dirty or the liquid dripping does not become so serious, so the merit of using the liquid discharge tool 3, 3A, 3B, 3C, 3D for the water tank is not so high. However, the same problem may be important depending on the place and the user.
