Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application field] In the present invention, a refueling amount indicator and a preset button for presetting a refueling amount are provided on a front face, and a refueling hose connected to a refueling hose is provided at a nozzle hook. The present invention relates to a kerosene weighing machine used for a weighing machine with a nozzle.

[Prior art] As is well known, kerosene is frequently used as an inexpensive energy source for home heating, and gas stations and other gas stations are equipped with kerosene metering machines. Refueled and sold. By the way, kerosene has an unpleasant smell when spilled when refilling a petroleum stove from a plastic tank at home, and a little unpleasant smell immediately after the stove is burned, which is unpleasant. Due to this discomfort, energy sources for home heating have recently tended to shift from cheap kerosene to expensive gas and electricity. Therefore, it has been proposed to add a fragrance to kerosene.

In general, various techniques for adding additives to liquids are known, for example, Japanese Utility Model Laid-Open No. 59-186300 and Japanese Utility Model Laid-Open No. 59-1889.
No. 00 and JP-A-58-41099. However, all of these known techniques continuously add or mix at a constant rate, and a simple apparatus is desired when the amount of refueling is known in advance such as kerosene.

[Problems to be Solved by the Invention] Accordingly, an object of the present invention is to provide a kerosene weighing machine capable of efficiently improving the odor of kerosene at a gas station.

[Means for Solving the Problems] According to the present invention, an indicator of the refueling amount and a preset button for presetting the refueling amount are provided on the front face, and a refueling nozzle connected to a refueling hose is hooked on the nozzle hook. Weighing machine, a plurality of fragrance tanks and a weighing pump that sends a fixed amount of fragrance, a suction pipe connected to the weighing machine, a discharge pipe, a hose connected to the discharge pipe, and a fragrance nozzle connected to the hose. A perfume refueling nozzle hung on a hook, a liquid level sensor is provided at the bottom of the perfume tank, the metering pump is provided with a pump lever for discharging a certain amount of perfume, and the pump lever is provided with a perfume pump. A refill lamp is provided which protrudes into the indicated recess and which is turned on when the perfume in the perfume tank is below a minimum amount based on a signal from the liquid level sensor.

[Explanation of operation and effect] Therefore, when supplying kerosene to the plastic tank, before or after refueling, first check the presence or absence of the fragrance desired by the customer with a refill lamp, insert the fragrance supply nozzle into the plastic tank, and set the pump lever. Press down with. Then, the fragrance in the fragrance tank passes through the suction pipe, flows from the metering pump to the discharge pipe, and is supplied from the fragrance supply nozzle into the plastic tank via the hose.

In addition, the supply amount of the fragrance is about 50 cc regardless of whether kerosene is 18 liters or 20 liters.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1 and FIG. 2, a display 2 of “kerosene”, a display 3 of a refueling amount, and
Preset buttons 4a and 4b for presetting 18 liters and 20 liters of refueling are provided, and a refueling nozzle 6 connected to a refueling hose 5 is hung on a nozzle hook 6a, which is the same as a conventional kerosene meter. It is.

In the present invention, in addition to the refueling nozzle 6, a fragrance supply device for supplying three types of fragrances (apple, orange, and lemon in the illustrated example) is provided.

The fragrance supply device includes fragrance tanks 11a, 11b and 11c provided inside the weighing machine 1 (hereinafter, when collectively referred to, the reference numeral 11 is used, and a code excluding all subscripts is used);
A metering pump 13 for feeding a certain amount of fragrance, a suction pipe 15 and a discharge pipe 16 connected to the metering pump 13, a hose 17 connected to a part of the discharge pipe 16 extending outside the measuring machine 1,
It comprises a perfume supply nozzle 18 connected to a hose 17 and hung on a perfume nozzle hanger 20.

A liquid level sensor 12 is provided at the bottom of the fragrance tank 11, and the metering pump 13 discharges a fixed amount (for example, 50 cc) of fragrance when the pump lever 14 is pressed down. Is provided with a concave portion 22 provided with a fragrance display 21 above, and the pump lever 14 projects into the concave portion 22. Note that reference numerals 19a, 19b and 19c in the figure are refill lamps, which are turned off when there is a minimum amount of fragrance or more in the fragrance tank 11, based on a signal from the liquid level sensor 12, and turned on when there is no fragrance. Has become.

When refueling fragranced kerosene, first refill lamp
After confirming the presence or absence of the fragrance desired by the customer by 19, the fragrance supply nozzle 18 is inserted into the plastic tank, and the pump lever 14 is depressed to supply 50 cc of the fragrance. Next, the preset button
Press 4a or 4b and insert the refueling nozzle 6 into the plastic tank to replenish kerosene. The addition of the fragrance may be performed after the supply of kerosene.

[Effects of the Invention] As described above, the present invention has the following excellent effects.

(A) When the kerosene is sold, the operation is simple because the fragrance can be added and sold by simply inserting the fragrance supply nozzle of the selected fragrance into the plastic tank and moving the pump lever.

(B) Since the fragrance supply device is mainly composed of a fragrance tank and a manual metering pump, the structure is simple.

(C) Customers are free from unpleasant smells when refueling a stove or when burning or extinguished, and can use inexpensive kerosene as an energy source for home heating. Gas stations can contribute to the promotion of kerosene.
