Description

  The present invention relates to an oil supply pump for supplying oil to a cartridge tank of an oil stove.

  Household and commercial oil stoves such as oil fan heaters are equipped with fixed oil tanks or removable cartridge tanks, and portable oil pumps (kerosene pumps) are used to supply oil tanks and cartridge tanks. . This oil supply pump supplies oil from a storage tank such as a 20-liter container such as a plastic container or a drum can to an oil tank fixed to an oil stove or a detachable cartridge tank. A manual oil supply pump including a pneumatic pump, Various types are commercially available, such as an electric oil pump with an automatic stop function that automatically stops the oil supply operation, and an electric oil pump that stops the oil supply operation manually.

  Petroleum stoves equipped with a cartridge tank are popular because they can be removed and transported to a location where a plastic container is located, and the cartridge tank can be refueled using a fuel pump from the plastic container. However, in many cases, the place where the plastic container is located is outdoors, and it is inconvenient to refuel the cartridge tank from the plastic container in the dark place outdoors at night. Oil supply pumps that eliminate such inconvenience at the time of refueling are not commercially available, and are not found in patent documents or other technical documents.

  In order to make it easier to refuel the cartridge tank from a plastic container in a dark place outdoors at night, lighting equipment such as an outdoor light will be installed in the place where the poly container is located, and illuminate before starting the refueling work However, it is uneconomical to have lighting equipment only for the convenience of refueling work. So, in fact, we are refueling while holding the flashlight in one hand and illuminating the periphery of the cartridge tank and the plastic container, but this work is quite inconvenient. For example, an electric oil supply pump is heavy with an electric motor for sucking oil from a plastic container and a dry battery (two single batteries are usually used) for driving the electric motor, and has a poor weight balance. It is difficult to handle an electric oil pump with one hand without an electric light. In addition, although the manual oil pump is lightweight, it is difficult to continuously perform the pump operation with one hand without a flashlight, which is inconvenient.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a convenient oil supply pump that facilitates an oil supply operation in a dark place.

  The present invention connects a suction part that sucks in oil, a discharge part that discharges oil sucked in the suction part, and connects the suction part and the discharge part in communication, and sucks oil in the suction part to the discharge part. In an oil supply pump having a main body provided with a pump operating means for discharging, an illuminating unit having a light emitting diode as a light source is disposed in the main body.

  Here, the suction part of the oil supply pump includes a hard pipe inserted into the oil in the storage tank such as a plastic container, and sends the sucked oil to the discharge part. The discharge unit includes a bellows-like flexible discharge hose that discharges oil into a tank such as a cartridge tank of an oil stove, and a base end portion of the discharge hose communicates with the suction unit. The main body portion is a portion that performs a pump operation in which oil is sucked into the suction portion and delivered to the discharge portion, and has either an electric type or a manual type configuration. In the case of an electric main body, it has a cylindrical case (battery case) structure with a built-in dry battery, and is equipped with power switches for pump operating means for manually operating driving and stopping of an electric motor installed in the suction portion. In the case of a manual type main body, a pump operating means for sucking oil with a negative pressure in the suction section is equipped. In particular, in the case of a pneumatic manual type main body, a pump operating means for increasing the air pressure in the storage tank is equipped. .

  The illumination unit disposed in the main body uses a high-intensity light-emitting diode (hereinafter referred to as LED as necessary) as a point light source. As the LED, a single product such as a white LED, a green LED, and a red LED, a plurality of products having the same emission color, or a plurality of products having different emission colors can be applied. Moreover, in the use which illuminates the field of the oil supply work with an illumination part, white LED is the most practical and desirable. The illumination unit using the LED as a light source can be disposed on a part of the side surface of the main body or on the end surface of the main body, and does not interfere with the refueling work by being disposed on the main body. Moreover, the illumination part can be made into the structure provided with the reflecting plate which reflects the light of the lighted LED, reflects the light of LED with good directivity toward the outside efficiently by the reflecting plate, and externally Illuminate the cartridge tank. By illuminating with the LED in this way, refueling work in a dark place using a fuel pump becomes convenient. In addition, since the LED does not light up with high heat like a light bulb or is not damaged, it can be refueled in a safe working environment.

  The present invention relates to an electric oil pump having an electric motor in which a suction part of an oil supply pump includes an electric motor that sucks oil, and a main body part including a dry battery that drives the electric motor. Can be turned on as a power source.

  In this case, the dry cell of the main body is usually used by connecting two single dry cells or two single dry cells in series. The dry cell drives the electric motor of the suction unit, and if necessary, By turning on the LED of the illumination unit, a dedicated power source is not necessary for the LED, and it is not necessary to provide a dry cell storage space in the illumination unit itself, and the illumination unit can be made small and compact and inexpensive. . Further, since the LED is lit with high brightness with a small current, it hardly affects the life of the dry battery and the performance of the electric oil pump.

  Moreover, in this invention, it can be set as the electrically driven oil supply pump provided with the manual power switch which the main-body part drives the electric motor of a suction | inhalation part, and the manual illumination switch which lights LED of an illumination part. In this case, by independently operating the power switch and the lighting switch, it is possible to select and perform the refueling operation and the lighting operation independently. It can be used in a convenient way such as refueling or lighting operation only when necessary, such as during refueling.

  Moreover, it can be set as the structure provided with the manual type power switch which drives a light-emitting diode of a lighting part while a main-body part drives an electric motor. In this case, since one power switch also serves as a lighting switch, the number of switch operations for the refueling operation and the lighting operation can be reduced, and the number of switches to be used can be minimized so that the size can be reduced and the manufacturing cost can be reduced.

  In this invention, it can be set as the structure where an illumination part is integral with a main-body part. For example, when both the main body part and the illuminating part have a container shape, a part of the container of the main body part can be integrally protruded, and a part of the protruding container can be used as the container of the illuminating part. By integrating the lighting part and the main body part in this way, both can be manufactured at the same time, and when the main body part has a resin container, the resin container of the lighting part can be formed at the same time when molding the resin container. Can be manufactured inexpensively.

  Moreover, it can be set as the structure which an illumination part can attach or detach to a main-body part. In this case, there is the convenience that the illumination part can be used by removing it from the main body part, and a special illumination part mounting structure is formed on the main body part, for example, by making the illumination part fit into the main body part and detachable. There is an advantage in the design of the oil pump that can be applied to the main body of the oil pump of an existing shape that is not necessary.

  Further, in the present invention, the illumination unit has a projecting member projecting from a part of the side surface of the main body unit and a light projecting window that forms a part of the outer surface of the projecting member, and an LED is placed behind the projecting window. It can be a deployed structure. The projecting member here projects in a triangular block shape, a square block shape, a semicircular shape, etc. from the side surface of the main body part. By disposing at a fixed position protruding from the side surface, it is possible to easily illuminate the periphery of the main body part and the side surface of the main body part itself from a position away from the side surface of the main body part. The projection window formed on a part of the projecting member is composed of a lens for converging the LED light, a transparent glass plate for transmitting the LED light, a colored glass plate colored with this glass plate, and the LED itself. It can also be an exposed window.

  In this invention, it can be set as the structure where the said protrusion member has the slope which faces the side in which the suction | inhalation part of an oil supply pump exists, and provided the light projection window in this slope. In this case, the illuminating part has a triangular block shape, the bottom part of which constitutes the side surface of the main body part, one of the two oblique sides becomes a slope with a light projection window, and this slope faces the suction part side. The light projecting window is directed to the suction part side, and the light of the LED projected from the light projecting window is concentratedly irradiated to the main part on the suction part side. The suction part side with respect to the main body part is on an oil supply side such as a cartridge tank for supplying oil, and can efficiently illuminate the cartridge tank etc. on the side supplied with the illumination part from the projection window without waste. it can.

  In addition, depending on the type of the fuel pump, an LED-dedicated dry battery that turns on the LED can be installed in the illumination unit itself. One AA battery can be applied to this LED-only dry battery. The illumination unit equipped with such a dry battery may be manufactured as a single product with an independent LED lighting circuit built-in and detachably attached to the fuel pump.

  According to the fueling pump of the present invention, the light emitting diode of the illumination unit can be turned on during the fueling work to illuminate the work site, and an excellent effect of making the fueling work in the dark place convenient can be achieved. Moreover, the illumination part arrange | positioned in the main-body part of a fueling pump can be installed in the position which does not interfere with a fueling operation | work, and handling of the fueling pump with a lighting part is made easy. In addition, light emitting diodes do not emit light or break like incandescent light bulbs, facilitating refueling work under safe lighting, especially white light emitting diodes that allow clear lighting and make refueling work even easier. Make things. In particular, in the case of an electric oil supply pump, the light emitting diode can be lit with a dry battery for driving an electric motor, and an oil supply pump with high practical value can be provided.

  Hereinafter, various embodiments of the present invention will be described with reference to FIGS.

  An oil supply pump 10 shown in FIGS. 1A and 1B is an electric oil supply pump with an automatic stop function, and a main body part 20 and a suction part extending in a bifurcated manner from a connecting pipe 21 provided at the lower part of the main body part 20. 30 and the discharge unit 40, and the illumination unit 50 is integrally disposed on a part of the side surface of the main body unit 20. The components other than the illumination unit 50 of the fuel pump 10 may have a structure similar to that of the existing electric fuel pump with an automatic stop function, and for example, the following structure.

  The suction part 30 is a part for sucking oil from a 20-liter plastic container 1 as shown in FIG. 2, for example, and includes a single long suction pipe 31. A base end portion of the suction pipe 31 communicates with the connecting pipe 21 of the main body portion 20, and an electric motor M shown in FIG. The discharge unit 40 includes a long and flexible discharge hose 41. The base end portion of the discharge hose 41 communicates with the base end portion of the suction pipe 31 via the connecting pipe 21, and the oil sucked into the suction pipe 31 is discharged to the discharge hose 41. A nozzle 42 is connected to the tip of the discharge hose 41. The nozzle 42 is a hard tube inserted into the oil inlet / outlet pipe 7 of the oil stove cartridge tank 5 as shown in FIG. 2, and has a hooking claw 43 that holds the posture of the nozzle 42 inserted into the oil inlet / outlet pipe 7. This nozzle 42 incorporates a switch S2 for automatically stopping the refueling operation shown in FIG. 1 (C), which senses this when the cartridge tank 5 is filled and approaches a full state. The switch S2 is automatically operated by the sensing unit 45 and the stop line 44 at the tip of the nozzle 42 in FIG. In addition, a locking portion 46 projects from a part of the side surface of the nozzle 42. As shown by the chain line in FIG. 1A, the discharge hose 41 is bent so that the nozzle 42 is brought close to the connecting pipe 21 and the engaging portion 46 is hooked on the hook 22 protruding from the connecting pipe 21.

  The main body 20 includes a dry battery that operates the electric motor M, for example, a battery case 23 that houses two single dry batteries or single dry batteries E and E in series, and a power switch S1 installed on the side of the battery case 23. . The battery case 23 is a vertically long cylinder having a lower end connected to the connecting tube 21 and a lid 24 detachably screwed to the upper end. A hanging projection 25 is integrally formed on the lid 24. The power switch S1 shown in FIGS. 1A and 1B is a manual switch having an ON switch and an OFF switch, but may be a slide switch.

  The embodiment of FIG. 1 is characterized in that an illumination unit 50 is integrally formed on a part of the side surface of the battery case 23 of the main body unit 20. The illumination unit 50 includes a white light emitting diode D and an illumination switch S3 illustrated in FIG. The illumination unit 50 includes a protruding member 51 that is, for example, a triangular block-shaped resin case, and the bottom side of the triangular protruding member 51 is fixed to the side surface of the battery case 23 by bonding or screwing. A projection window 54 is formed on one of the two inclined surfaces 52 and 53 of the protruding member 51, and a lighting switch S3 is installed on the other. A white light-emitting diode D is installed in the back of the light projection window 54, and a reflector (not shown) is installed around it. The light of the lit white light-emitting diode D directly and reflects off the reflector to project the light-projection window 54. From the outside to the outside with good directivity The slope 52 with the light projection window 54 is a slope that slopes downward when the main body 20 is put in a standing posture for a fueling operation, and the other slope 53 is a slope that slopes upward. The white light emitting diode D of the illumination unit 50 and the illumination switch S3 are connected in series via a resistor R, and this series circuit is wired to the main unit 20 as shown in FIG.

  Next, the fueling operation by the fueling pump 10 of the above embodiment will be described.

  For example, as shown in FIG. 2, when refueling from the polycontainer 1 to the cartridge tank 5 in a bright place, the normal refueling operation is performed with the illumination switch S3 turned off. The suction pipe 31 is inserted into the inlet / outlet port 3 of the plastic container 1, the nozzle 42 of the discharge hose 41 is inserted into the oil inlet / outlet pipe 7 of the cartridge tank 5, and is stopped by the hooking claws 43, and the power switch S 1 of the main body 20 is turned on. Then, automatic refueling is performed. When the cartridge tank 5 is filled up to a predetermined full level, the automatic stop switch S2, which is a normally closed switch of the nozzle 42, is turned OFF and the fueling operation is automatically stopped.

  When refueling from the plastic container 1 to the cartridge tank 5 in a dark place, the illumination switch S3 is turned on before the refueling operation. Then, as shown in the electric circuit of FIG. 1C, a battery current flows through the white light emitting diode D to light it, and the surroundings are illuminated, so that it is easy to perform a refueling operation in a dark place. At this time, the battery current also flows through the electric motor M. However, since the electric current is small enough to light the light emitting diode, the electric motor M does not operate, and the consumption amount of the dry battery E is so small that there is no problem. In a state where the white light emitting diode D is turned on, the refueling operation of FIG. 2 is performed. At this time, since the light projection window 54 of the illumination unit 50 is on the downward slope 52, the light projection window 54 can be directed to the cartridge tank 5, and in this way, light from the light projection window 54 can be used for the cartridge tank. 5 can be intensively illuminated. In this case, if the indicator 8 provided on the side surface of the cartridge tank 5 is illuminated, it is convenient that the amount of oil can be visually recognized. If the discharge hose 41 is illuminated, the oil flowing through the discharge hose 41 can be visually confirmed, and the oil supply is normal. Can be confirmed. Note that reference numeral 6 in the cartridge tank 5 in FIG. 2 is a tilting handle, reference numeral 2 in the plastic container 1 is an entrance / exit cap, and reference numeral 4 is a handle portion.

  Even after the refueling operation to the cartridge tank 5 is automatically stopped when the switch S2 is turned off, if the illumination switch S3 is kept on, the illumination by the white light emitting diode D is continued, and cleaning up after cleaning is completed. It becomes easy to do, and the trouble of overflowing oil in the dark and polluting the surrounding area is eliminated. The illumination switch S3 may be manually turned off at any time after refueling.

  Next, other embodiments will be described in order.

  FIG. 3 shows an electric circuit diagram in which the electric motor M is driven by the power switch S1 and the white light emitting diode D is turned on. For example, a series circuit of a light emitting diode D and a resistor R is connected in parallel to the automatic stop switch S2, and when the power switch S1 is turned on, the electric motor M is driven through the normally closed switch S2, and the white light emitting diode D is turned on. Thus, the refueling operation and the lighting operation are performed simultaneously. Further, even if the refueling operation is automatically stopped when the automatic stop switch S2 is turned OFF, the illumination operation is continued until the power switch S1 is turned OFF. This also facilitates refueling work in the dark.

  The embodiment shown in FIGS. 4A and 4B shows an example in which the illumination unit 50 is integrated into the power switch S1 of the main body unit 20. The power switch S1 is used in the electric circuit of FIG. The power switch S1 has a structure including a vertically long housing 26 made of resin, and an illumination unit 50 is integrally formed on the upper portion of the housing 26 so as to bulge outward, and is projected onto a downward slope 52 of the illumination unit 50. A window 54 is installed. Since the light projection window 54 faces the power switch S1 and illuminates the power switch S1, it is convenient to manually operate the power switch S1 in a dark place.

  5A and 5B show an example of an oil supply pump 10 in which the illumination unit 50 is detachably attached to the main body unit 20. The illuminating unit 50 in FIG. 5 has a structure in which an elastic mounting band 55 as shown in FIG. 6 is formed integrally with a protruding member 51 ′ similar to the protruding member 51 of the illuminating unit 50 in FIG. The battery case 23 of the main body 20 is detachably attached. In addition, the main body 20 is wired with a telescopic curl cord 56 led out from the protruding member 51 '.

  FIG. 5A shows a state in which the illumination unit 50 is attached to the main body unit 20. In this state, the same oil supply operation as that in FIG. 2 is performed. In this refueling operation, when the illumination effect by the illumination unit 50 is poor, as shown in FIG. 5B, the illumination unit 50 is removed from the main body unit 20 and moved to a place where the illumination unit 50 is desired to be illuminated. Good lighting effect can be obtained. The illumination unit 50 removed from the main body unit 20 can be held with one hand or can be hooked on a shelf board (not shown) using the attachment band 55.

  Each of the above embodiments is an electric oil pump with an automatic oil supply stop function, but an electric oil pump without an automatic oil supply stop function, that is, an electric motor is driven by manually turning on a power switch to supply oil. It is also possible to apply the present invention to an electric oil supply pump that starts operation and stops the electric motor by manually turning off the same power switch to stop the oil supply. In this case, by illuminating the indicator of the cartridge tank on the side to be refueled with a white light emitting diode in the dark place, it is possible to visually recognize the timing of stopping the refueling operation and to prevent excessive refueling.

  7 and 8 show an embodiment applied to a manual oil pump.

  FIG. 7 shows the main body 20 composed of a pump operating means 20a which is a flexible container that sucks oil by making the inside of the suction part 30 into a negative pressure. The boundary part between the main body part 20, the suction part 30 and the discharge part 40 is shown in FIG. The illuminating unit 50 is detachably attached. In this case, the illumination unit 50 is equipped with a dry battery (not shown) dedicated to the light emitting diode.

  FIG. 8 shows a pneumatic manual oil supply pump. In this case, the main body portion 20 is constituted by a pump operating means 20b for increasing the air pressure in a storage tank such as a plastic container, and the illumination portion 50 is attached to and detached from the main body portion 20. Install freely. Also in this case, the illumination unit 50 is equipped with a dry battery (not shown) dedicated to the light emitting diode.
