The tap water is supplied to the water tube 1a of the water receptacle 1 and flows into the receiving space SP through the first projecting pipe 13a or the first overlapping pipe 13b constituting the first coupler 13 And flows into the inside of the filter 30.

The disinfection cap 60 disinfects the water introduced into the filter 30 through the water holes 63a of the perforated plate 63 while passing the water through the disinfectant 50.

The filter 30 filters the impurities contained in the tap water while discharging tap water discharged into the water supply hole 63a through the inner circumferential surface in a sterilized state by the disinfectant 50 and discharges the water to the outer circumferential surface.

The first hollow tube 11 and the second hollow tube 21 discharge the tap water discharged to the outer peripheral surface of the filter 30 through the flow path 40a and discharge the tap water to the second projecting pipes 23a and 23b.

Accordingly, the tap water is jetted through the jet head 1b coupled to the second projecting pipes 23a, 23b and supplied to the sink.

As described above, according to the present invention, tap water that flows through the receiving space SP of the first housing 10 and the second housing 20 is filtered by the filter 30 to remove the impurities The tap water of the sink can be used safely because it is flooded in the state.

Alternatively, when the first coupler 13 is constituted by the first superposition pipe 13b, the water tube 1a is coupled with the first hollow tube 11 in an overlapped state, so that the water tube 1a, for example, The breeze can be installed without shortening the length of the flexible tube even if it is formed as long as the flexible tube.

In addition, the second hollow tube 21 constituting the second housing 20 can be detachably connected to the jet head 1b through the second projecting pipes 23a and 23b.

In addition, since the second projecting pipe 23a is formed in a direction different from the longitudinal direction of the second hollow pipe 21, the jet head 1b can be coupled orthogonally with the second hollow pipe 21, The other end of the second hollow tube 21 is curved 21a so that when the jet head 1b is configured to be orthogonal to the pipe-like water tube 1a, the projecting length of the jet head 1b May be installed in a state in which the distance is reduced.

Furthermore, when the second projecting pipe 23b is formed in the same direction as the longitudinal direction of the second hollow pipe 21, for example, the water pipe 1a is suitable for the power receiving member 1 formed of a flexible pipe.

Since the spacing vanes 43 constituting the spacer 40 protrude in the longitudinal direction and the width direction of the filter 30 and are brought into close contact with the second housing 21, the space between the filter 30 and the containing space SP The flow path 40a is secured and the filter 30 does not flow away from the accommodation space SP.

In addition, since tap water is filtered by the filter 30 and is disinfected and sterilized by the disinfectant 50, the tap water of the sink can be used more reliably.

In addition, since the first housing 10 and the second housing 20 are formed of a transparent body and the filter 30 is accommodated in a transparent manner, the filtering state and the replacement timing of the filter 30 can be visually confirmed.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.
