Description

[Detailed Description of the Invention] The present invention relates to an improvement of a fuel pump, particularly a household fuel pump in which a filter member is provided.

Household oil pumps suck up oil by pressing and releasing the pressure part, and discharge it by pressing it again, repeating this process to refuel oil stoves, etc., but conventional oil pumps There were almost no means for removing drainage and dust from the oil being sucked up, and these were often used together when refueling.

Recently, fuel pumps equipped with a dust prevention device to remove such dust have been proposed, for example, in Japanese Utility Model Application Publication No. 50-20205, but these pumps are simply equipped with a dust prevention device. After that, no consideration is given to removing the attached dust.

Moreover, even if dust can be removed using the method according to the above-mentioned publication,
The condensate, including the mixed water, returns to the original oil can.

On the other hand, regarding the drain retention section, the Utility Model No. 53-1
Although a separate proposal has been made in Japanese Patent No. 09805, a filter member is not used in this, and it is not possible to actively remove dust.

This invention improves the deficiencies of conventional oil pumps as mentioned above,
Another object of the present invention is to provide a filter member that can be easily interposed in the oil supply pipe of an oil supply pump and can perform effective dust removal and drain removal functions.

Hereinafter, embodiments of the oil supply pump of the present invention will be described with reference to the accompanying drawings.

Fig. 1 shows an example of the pump according to the present invention. In the figure, 1 is a refueling pump pressing part, 2 is a suction pipe, 3 is a discharge pipe, and 4 is a check valve. A filter member 5 is interposed in a part of the suction pipe.

Here, the suction pipe 2, the discharge pipe 3, the suppressing part 1, etc. are molded from synthetic resin, and have flexibility as is known.

The filter member 5 is a main part of the present invention, and the case main body 6 is divided into two parts, upper and lower, which are formed so that they can be freely fitted and removed by screwing together. That is, the upper bottle cap-shaped ceiling surface and the lower bottom lip-shaped bottom surface are each provided with a short pipe member 7, which penetrates the closed surface and extends from inside to outside. 8. 910 is provided protrudingly.

Inside the separable case body 6, a short pipe member 8 extending inwardly into the bottle lid-shaped L-portion case body is inserted into the center thereof, and a cylindrical sliding member 11 is held therein. The lower free end side of the cylindrical sliding member 11 is elastically supported by a spring 12 interposed between it and the inner surface of the lower case body.

In this case, the spring 12 is held with a short pipe member 9 extending inwardly inserted into the center of the lower part of the lower Kennis body.

Therefore, the spring interposed part of the cylindrical furnace material 11F, ie, the outer peripheral part of the short pipe member 9, forms a retention part for the drain and the like.

The case body 6 is made of a transparent material so that the accumulation of dust and drainage inside can be visually confirmed.

A desirable material for this purpose is a transparent synthetic resin.

In addition, the case body 6 is made in the shape of an inverted truncated cone with a small diameter at the bottom and gradually widening towards the second part, so that when the suction pipe is inserted into the opening of a household oil can, etc. It also serves as a plug to seal the area.

Further, although the case body 6 is formed separately from the conventional oil supply pump in each case shown in the figures, it is possible to achieve the same purpose even if the case body 6 is formed continuously and integrally with the lower end of the branch at the lower part of the pressing part 1. I can do it.

However, in order to improve an existing oil supply pump, it is preferable to install it as a separate unit.

In the figure, reference numerals 13 and 14 are members for joining and fastening the flg to the existing suction pipe 2, such as the short vibe members 7 and 1o.

The pump of the present invention has a structure similar to that described above, and its operation will now be described. When the oil in the oil can rises through the suction pipe 2 according to normal operation, the oil flows downward. It enters the inside of the case body 6 through the short pipe members 10 and 9 extending thereinto, penetrates the internal cylindrical sliding material 11 from the outside toward the center, and penetrates the short pipe members 7 and 8 above the center part. The oil then passes through the check valve 4 and is discharged from the branch to the discharge pipe 3 side. At this time, the dust contained in the oil is removed by the lubricant 11, and the water is removed from the case body 6. The oil is separated from the oil in the lower chamber containing the spug 12, becomes drain and accumulates in the lower part, and only the oil passes through the holder f411.

If it is visually confirmed that a certain amount of dust and drainage has accumulated inside the transparent case body 6 due to repeated use, the case body 6 can be divided into parts as appropriate.
1. Remove, replace, or wash.

Also, drain accumulated at the bottom should be removed. Thus, again,
Oil can be purified in the same way.

As described above, in the present invention, a filter member with a built-in cylindrical rod material is inserted in the splittable case body in the middle of the plate pipe of the oil supply pump, so that oil can be supplied using the pump. In this case, it is possible to supply clean oil by removing dust drain from the oil, and to improve combustion efficiency.In addition, the filter member is particularly formed by a splittable case and a cylindrical sliding member. The materials can be taken out at any time, so... It has the advantage that when dust accumulates on one piece of material, it can be easily opened and replaced or cleaned at any time.Furthermore, inside the case body, the door material is located at the top, and the bottom is a spring. In addition to being supported by
Since a short pipe member is protruded inward, a drain retention section is formed at the bottom to improve the separation of contained moisture.
It has various remarkable effects such as increasing the filtration efficiency of the lubricant.

In addition, the filter member installed in the fuel pump of the present invention can be easily attached to an existing fuel pump using a short pipe member that projects outward, allowing the user to simply install the fuel pump in each home. It can be modified by simply cutting the pipe in the section where it is intended to be used, and its shape is an inverted truncated cone that expands upward so that it can fit into the opening of a household oil can, making it easy to siphon. It is possible to securely hold the pipe, and since the case body is transparent, it has an excellent effect in that it is possible to visually check the amount of drain accumulated inside.
