[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a liquid discharge device, and is particularly suitable for use in a liquid discharge device for supplying kerosene contained in a plastic container to a cartridge of an kerosene heater. It is something.

[Summary of the Invention] A pump means is provided inside the cylindrical body, and a suction side is connected to the discharge port of the pump means, and a discharge hose is housed inside the cylindrical body, and the discharge hose is formed to be expandable and retractable. By this, the discharge end of the discharge hose can be pulled out to the outside of the cylindrical body to supply liquid to a desired discharge destination, and the entire hose can be stored inside the cylindrical body when not in use. This is a liquid discharging device.

[Prior Art] For example, a fuel pump is used as a liquid discharge device for pouring kerosene contained in a plastic container into a kerosene stove. A conventional oil supply pump has a pump body 50 made of an elastic member, as shown in FIG.
This pump body 50 is provided with an inlet and an outlet, a suction pipe 51 is connected to the inlet, and a long discharge hose 52 is connected to the outlet.

[Problems to be Solved by the Invention] When the pump is not in use, it is removed from the plastic container and stored. However, when it is removed, the liquid gets on your hands or drips onto the floor, making it troublesome to store and store. For this reason, the pump is often left inserted into the container, but the discharge hose 52 becomes a hindrance at such times.

SUMMARY OF THE INVENTION In view of the two problems, the present invention aims to prevent the discharge hose from getting in the way when not in use.

[Means for Solving the Problems] The liquid discharge device of the present invention includes a cylinder (outer cylinder 1) whose upper end is open and in which a liquid discharge port 9a of a pump means is provided.

It is equipped with a telescopic discharge hose 18 whose end can be drawn out to the outside of the cylinder 1.

[Function] Since the discharge hose 18 can be stored inside the cylindrical body 1, the discharge hose 18 does not get in the way when not in use. Since the discharge port 18 is expandable and retractable, when in use, the end of the discharge side 20 can be pulled out to the outside of the cylindrical body 1 and the liquid can be discharged to a destination.

[Embodiment] FIG. 1 is a front view of a liquid discharge device showing an embodiment of the present invention, and FIG. 2 is a sectional view thereof.

As shown in FIGS. 1 and 2, this liquid discharge device has an outer cylinder 1 and an inner cylinder 2 slidably fitted together to form a pump means. The outer diameter of the outer cylinder 1 is formed to match the inner diameter of an opening 4 provided in a plastic container 3 (see FIG. 4) for storing kerosene. Further, its length is formed to match the height of the plastic container 3.

A suction port 5 is provided in the lower part of the outer cylinder 1, so that the kerosene contained in the plastic container 3 can be sucked into the outer cylinder 1, that is, into the main body of the pump means. In the example shown in FIG. 2, the tip of the outer cylinder 1 is formed to have a small diameter, and a steel ball 6 is mounted on the narrowed part to form the suction port 5 of the pump means.

A circular container-shaped mounting body 30 with an open bottom surface is provided on the circumferential surface of the upper end of the outer cylinder 1, and an internal threaded portion 8 is formed on the inner surface thereof. This mounting body 30 has an internal threaded portion 8.
is formed, and the pump is attached to the plastic container 3 by screwing the internal thread 8 into the external thread 7 of the opening 4 provided in the plastic container 3. Therefore, the outer cylinder 1 is inserted into the plastic container 3 and is securely attached.

The inner cylinder 2 is slidably fitted into the outer cylinder l. In this embodiment, the inner cylinder 2 is composed of two cylinder bodies 2a and 2b7'.

A pressing plate 9 is provided at the lower end of the cylinder 2a. This pressing plate 9 moves up and down while sliding along the inner surface of the outer cylinder 1, and makes the pressure in the pump space formed by the outer cylinder 1 and the inner cylinder 2 negative or positive. The kerosene in the plastic container 3 is sucked and discharged.

A discharge port 9a is formed in the center of the press plate 9,
When the inner cylinder 2 is moved downward, the kerosene that has been sucked into the pump means is discharged outside the pump body.

A discharge pipe 1 connected to the discharge port 9a is provided on the upper surface of the press plate 9.
0 is provided, and this discharge pipe 10 is provided with a pressure plate 9 as described in
A valve body 11 is provided that opens when the press plate 9 moves downward and closes when the press plate 9 moves upward. Second
The valve body 11 shown in the figure is normally open and is configured to close when the inner cylinder 2 moves upward, that is, when kerosene is sucked into the pump body. The lower part of the outer cylinder 1 and the pressing plate 9
The spring 12 provided between the pressing plate 9 (
This is for pushing up the inner cylinder 2). The cylindrical body 2b is slidably fitted to the outside of the cylindrical body 2a,
When the pump is not in use, the outer cylinder 1 is
A circular presser plate 13 provided at the upper end of the vI body 2b that is housed inside prevents the cylinder body 2b from entering the outer cylinder 1, and also prevents the inner cylinder from moving up and down by pressing this presser plate. This is to make it possible to do so. An opening 13a is formed in the center of the holding plate 13, and a discharge port, which will be described later, can enter and exit the inner cylinder 2 through this opening 13a.

An engaging protrusion 15 protruding from the cylinder 2a is slidably fitted into a slide lug 14 formed along the longitudinal direction on the circumferential surface of the cylinder 2b. Above slide 14
The lower end of the cylinder body 2 is bent in the radial direction by a predetermined length, as shown by the arrow 16 in FIG.
After pulling out the cylinder 2b outward, by rotating it in the radial direction as shown by the arrow 17, the cylinder 2b can be fixed to the cylinder 2a while being pulled out. The above discharge pipe 10
One suction side of the discharge hose 18 is connected to. This discharge hose 18 is formed to be expandable and contractible, and is normally housed in the cylindrical body 2a in a contracted state due to its own elasticity. When stored, only the engaging body 21 attached to the end of the discharge side 20 of the discharge hose 18 is exposed to the outside of the inner cylinder 2 and the outer cylinder 1.

As shown in the first FJ, the engaging body 21 is formed in the shape of a circular container with its opening facing the discharge side, and as shown in FIG. It is designed to be able to be connected by mating.

Note that if the engaging body 21 is provided with a slit, engagement with the fuel filler port can be performed elastically.

FIG. 4 shows the state of use, in which the engaging body 21 is fitted and connected to the fuel filler port 23 of the cart/tuck 22, and when the inner cylinder 2 is pushed down as shown by the arrow 24 in FIG. The kerosene that has been sucked into the pump space between the suction port 5 of the cylinder 1 and the pressing plate 9 is discharged from the discharge side 20 of the discharge hose 18 into the cartridge tank 226. Also, when the depression of the inner cylinder 2 is released. , the inner cylinder 2 is automatically moved upward by the force of the spring 12, and kerosene is sucked into the pump body.

Therefore, by repeatedly moving the inner cylinder 2 up and down, the kerosene inside the plastic container 3 can be removed from the cartridge tank 22.
You can refuel inside.

As the fuel is refilled, the amount of kerosene decreases, and the pressure inside the plastic container 3 decreases, making it difficult to refuel. Therefore, openings 25 and 26 are formed in the cylinder body 2a and the outer cylinder 1, as shown in FIG. 2, so that air can flow into the plastic container 3 from the outside when the pressure decreases. IM means that when the pressure inside the plastic container 3 decreases, external air flows through the opening 25, the slide arm 4, and the opening 2 as shown by the arrow 27 in FIG.
6 and flows into the plastic container 3. An opening 28 is formed on the outer cylinder 1 below the pressing plate 9 in order to return the kerosene sucked up to the highest position indicated by the arrow 29 in FIG. 4 into the plastic container 3 at the end of refueling. As a result, the kerosene sucked up at the highest position t indicated by the arrow 29 can be naturally returned to the plastic container 3 by simply placing the inner cylinder 2 in the upper position at the end of refueling.

An external threaded portion 31 is formed on the peripheral surface of the mounting body 30, and a cap 3 as shown in FIG. 1 is attached to this external threaded portion 31.
2 can be installed. Thereby, the plastic container 3 can be hermetically sealed while the liquid discharge device is attached to the plastic container 3, that is, with the liquid discharge device housed inside the plastic container 3.

The discharge hose 18 is normally contracted due to its elasticity and is stretched during discharge, but it may be a hose that maintains the contracted state when it is contracted and maintains the extended state when it is extended.

Although the basic configuration is shown in this embodiment, various modifications can be applied without being limited to the above embodiment.

For example, the fitting manner of the cylinders 2a and 2b may be reversed, or the inner cylinder 2 may be made of a single wooden cylinder.

Further, a stopper may be provided on the inner surface of the outer cylinder 1 to restrict the upward movement position of the press plate 9, and a guide may be further provided to restrict the rotation of the press plate 9.

Further, a valve body may be provided in the suction port 5 instead of the steel ball 6,
A steel ball may be provided at the discharge port 9a instead of the valve body 1]. In addition, a spring is installed outside the cutter that can lift the steel ball slightly upwards when kerosene is sucked in, so that the kerosene automatically returns to the plastic container 3 when refueling is finished, as described above. .

Further, in order to return the kerosene in the hose to the plastic container 3 at the end of refueling, the valve body may be forcibly opened from the outside. Various such means can be considered, but for example, the valve body may be forcibly opened when the discharge hose is pulled upward. Note that the mounting body 3o and the outer cylinder 1 may be formed separately.

FIG. 5 shows an example in which the pump means is an electric pump.

That is, a motor 4o is provided below inside the outer cylinder 1, and a rotating blade 41 is attached to its output shaft 40a. motor 40
is sealed and when switch 42 is closed,
It rotates when a driving current is supplied from a battery 43 disposed inside the outer cylinder 1 . As the rotary vane 41 rotates, the kerosene in the plastic container 3 is sucked up and discharged through the discharge pipe 10.

FIG. 6 shows another embodiment of the electric pump means.

In this example, a liquid suction pipe 45 is provided at the lower part of the outer cylinder 1, and a rotor 46 is rotatably mounted within this liquid suction pipe 45. The rotor 46 is provided with rotating blades 41. A rotating magnetic field generating coil 47 is provided on the outer periphery of the liquid suction pipe 45.
is provided to generate a rotating magnetic field, and the rotor 46 is rotated to suck up kerosene.

[Effects of the Invention] As described above, in the present invention, the liquid discharge port of the pump means is provided inside the cylindrical body, the suction side of the discharge hose is connected thereto, and the discharge hose is formed to be expandable and retractable. When in use, the discharge side of the discharge hose can be pulled out to the outside of the cylindrical body, and when not in use, the entire discharge port can be housed inside the cylindrical body. Therefore, the discharge bowl does not get in the way when not in use and is easy to handle. Furthermore, since the discharge hose does not get wet even when the cylinder is inserted into the liquid, the cylinder can be stored with the discharge hose stored while the cylinder remains inserted into the liquid.
