Abstract

A receptacle for charging hydrogen is provided. The receptacle includes a main body formed at one side of a vehicle. A filter unit disposed within the main body filters the foreign substance in the hydrogen gas passing through the main body and a check unit disposed at the rear end of the filter unit controls a flow in one direction. The filter unit includes a mesh filter inserted into the filter socket formed at a first body of the main body and formed in a shape to filter the hydrogen gas passing through the main body, and a filter supporter disposed at the rear side of the mesh filter to closely support the mesh filter by coupling the second body and the first body and of which a plurality of gas apertures are formed to cause hydrogen gas passing through the mesh filter to flow to the check unit side.

First claim

What is claimed is:

1 . A receptacle for charging hydrogen in a vehicle, comprising:
a main body of the receptacle connected with a charging nozzle configured to supply hydrogen gas; a filter unit disposed within the main body of the receptacle to filter a foreign substance of the hydrogen gas passing there through; a mesh filter disposed within the main body of the receptacle and configured in a network shape to pass the hydrogen gas through the filter unit; and a filter supporter configured to supply the mesh filter and having a plurality of gas apertures through which the hydrogen gas flows to pass through the mesh filter.

2 . The receptacle for charging hydrogen of claim 1 , wherein a resistance coefficient plate in which a convergent aperture is formed to have a width decreasing in a direction where the hydrogen gas flows is disposed at one side of the filter supporter.

3 . The receptacle for charging hydrogen of claim 1 , wherein the gas apertures of the filter supporter are formed with a diameter having a size substantial enough to vent 3 to 6 apertures among the apertures of the mesh filter.

4 . The receptacle for charging hydrogen of claim 1 , wherein the mesh filter is formed in either a conical shape or a curved shape to maximize a filtering area.

5 . The receptacle for charging hydrogen of claim 4 , wherein the mesh filter is formed in either a conical shape or a curved shape to correspond to the shape of the mesh filter to correspondingly contact the mesh filter.

6 . The receptacle for charging hydrogen of claim 2 , wherein a check unit configured to prevent the hydrogen gas passing through the filter unit from flowing backward in an opposite direction is disposed within the main body of the receptacle.

7 . The receptacle for charging hydrogen of claim 6 , wherein: the check unit includes:
a valve plate disposed at a next position of the filter unit and having a valve aperture formed there through; a control rod disposed at the next position of the valve plate and having a closing and opening ball configured to open and close the valve aperture formed at one end; a rod supporter disposed at the next position of the control rod and configured to limit a movement position of the control rod; and a spring configured to provide elasticity between the control rod and the rod supporter and configured to contact the valve plate side to cause the closing and opening ball of the control rod to block the valve aperture.

8 . The receptacle of claim 1 , wherein the receptacle is disposed within a hydrogen vehicle.

9 . The receptacle of claim 1 , wherein the receptacle is disposed within a fuel cell vehicle.
