According to the application of this simple vertical trap structure to the present invention, the odor emitted from the lower drain pipe 3a or the sewer pipe 4 is communicated with the water 20 stored in the reservoir 13 by the vertical cap 50. Movement to the block is nevertheless, and the water flowing down from the upper cylinder 20 to the lower cylinder 10 nevertheless flows into the reservoir 13 and is discharged to the outlet 12 as the water level rises.

Further, when the trap of the vertical cap 50 is applied to the filtering device 1 of the present invention, it is not necessary to form an S-shaped or P-shaped trap in the drain pipe 3 of the wash basin, and the opening and closing cylinder 40 is Since the trap can be opened and the vertical cap 50 can be removed to clean the trap, the trap can be managed conveniently.

In the illustrated vertical trap, the upper end of the outlet 12 is the highest level of the reservoir 13, and the water passage 51 is formed at a position lower than the upper end of the outlet 12 in the vertical cap 50. As is well known in conventional bell traps.

When the trap of the vertical cap 50 is applied to the filtering device 1 of the present invention, the upper surface of the vertical cap 50 acts as the support part 11, and thus the filter barrel 30 is the vertical cap 50. ) Is put on. In the illustrated embodiment, a plurality of support protrusions 52 are formed on the upper surface of the vertical cap 50 to support the strainer 30, and such support protrusions 52 function as the support unit 11.

The filtering device 1 according to the present invention described above can be mounted on a drain pipe of a conventional wash basin equipped with a pop-up valve, and in particular, the patent application No. 10-2011-0014446 proposed by the present invention as an open / close valve of a sink. Particularly suitable for application to wash basin drainage pipes with a 'sink opening / closing valve' of (February 18, 2011).

The '446 basin opening and closing valve is a structure that almost no foreign matter such as hair contained in the drainage close to the on-off valve, when applying the filter device (1) of the present invention to the drain pipe of the wash basin equipped with such a valve, It is possible to reliably and easily realize the cleaning and cleaning of foreign matter which could hardly be realized in a sink equipped with a pop-up valve.
