JPH10120096A - Liquid feeder of liquid tank - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent a funnel from missing by connecting a strainer to a lower end of the umbrella-like funnel which can be opened/folded so that when the funnel is removed out of a liquid feed port of a liquid tank it can be opened for feeding liquid, while it can be folded to be received from the liquid feed port into the liquid tank. SOLUTION: A liquid tank B is a fuel tank or a chemical tank having a liquid feed port 1 covered by a cap on an upper part, wherein an umbrella-like funnel A which can be opened/folded like an umbrella is provided, and a strainer C is connected to a lower end of the funnel A. Thus when the umbrella-like funnel A is removed out of the liquid feed port 1 and it can be opened, while it can be folded to be received from the supply port 1 into the liquid tank B. The umbrella-like funnel A is formed by extending a thin vinyl sheet 5 or the like between respective ribs 4a, and a lower part of each rib 4a is coupled to an upper part of the strainer C so that the funnel A can be opened and folded like an umbrella.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid tank liquid supply device which can easily supply a liquid such as fuel or chemical liquid to the liquid tank without spilling the liquid.

[0002]

2. Description of the Related Art Conventionally, as disclosed in Japanese Patent Application Laid-Open No. 7-313812, it is known to provide a fuel filter inside a supply port of a fuel tank and provide a funnel which can be accommodated in the filter. I have.

[0003]

However, since the funnel can be accommodated in the fuel filter, the funnel cannot be formed large, and it is difficult to supply fuel with a small funnel. Since the pieces are connected by the connecting means, there is a problem that the airtightness between the funnel pieces is poor and fuel leaks from the connecting portion.

[0004]

SUMMARY OF THE INVENTION The present invention solves such a problem, and when the funnel is not used, the funnel is effectively stored together with the strainer in a tank so that the funnel is not lost. Therefore, a strainer is communicated with the lower end of the umbrella-shaped funnel that can be expanded or narrowed, and when the funnel is taken out from the liquid supply port of the liquid tank, the funnel can be expanded and the liquid can be supplied. It is configured such that it can be stored in the liquid tank from the liquid supply port by being narrowed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A liquid tank B shown in FIGS. 1, 4, 7 and 8 is a fuel tank or a chemical tank having a liquid supply port 1 for attaching a cap 2 at an upper portion, and is shown in FIG. The liquid tank B is a chemical liquid tank of a control device D such as a backpack-type control device which has a liquid supply port 1 with a cap 2 attached thereto at the upper portion and can be carried by a backing band 3, and is expanded or narrowed in an umbrella shape. An umbrella-shaped funnel A is provided, and a strainer C is communicated with the lower end of the funnel A. The umbrella-shaped funnel A can be expanded by being taken out from the liquid supply port 1 of the liquid tank B. The umbrella-shaped funnel A is formed by stretching a thin vinyl sheet 5 or the like between the bones 4a. The lower part of the bone part 4a is on the upper part of the strainer C, and the funnel A is umbrella-shaped. Linked to constitute to be able to or puckered spread or.

A ring 6a or a tightening band 6b shown in FIG. 4 is connected to a cap 2 attached to the liquid supply port 1 via a chain 10 or the like.
0 may be connected to some of the bones 4a.

Therefore, as shown in FIGS. 1 and 5, a fuel or a liquid such as a chemical liquid can be easily and satisfactorily supplied to the liquid tank B through the funnel A which is spread in an umbrella shape without spilling. Thereafter, the funnel A is squeezed into an umbrella shape and tightened so as not to be spread by the tightening band 6b. When you store it, you can store it well so that you do not lose it,
When the cap 2 is removed and the chain 10 is pulled up, the funnel A with the strainer C can be taken out of the liquid supply port 1 by the ring 6a or the tightening band 6b.

FIGS. 6 to 8 show that a funnel A made of a synthetic resin having a bent lower portion fixed to an upper portion of a stoner C is provided, and is formed by a thin portion 5a and a rib 4b serving as a bone. This is an example of a configuration in which a fitting vertical groove 7 is provided in the liquid supply port 1 and fitted.

Accordingly, as shown in FIG. 7, when the funnel A is taken out above the liquid supply port 1, the funnel A expands like an umbrella by elastic force. When the funnel A is pushed into the liquid tank B, as shown in FIG. The funnel A can be housed in the liquid tank B together with the strainer C by being drawn into an umbrella shape by the liquid supply port 1.

Since the funnel A can be housed in the liquid tank B while being umbrella-shaped, the funnel A can be formed large so that the liquid can be supplied easily and easily.

[0011]

As described above, according to the present invention, since the funnel A is formed so as to be able to be umbrella-shaped, it can be easily taken in and out of the liquid tank B by squeezing, so that it is not easily lost. It can be stored, and
When it is taken out from the liquid supply port 1 of the tank B, it can be spread in an umbrella shape, and can be supplied to the tank easily without spilling the liquid. Therefore, it has a feature that it can be easily implemented with a simple structure.

When the liquid tank B is used as a chemical tank of the control device D, this kind of chemical is harmful to the human body. Therefore, the chemical spills from the funnel A which is spread like an umbrella, and is harmful to the human body. It is possible to supply the chemical solution to the tank easily and easily.
