The mold faucet 14 could not be attached to these because the diameter of the connection port did not match. The present invention aims to eliminate the above defects.

[0004]

[Means for solving problems]

 In order to achieve the above object, the present invention provides a water purifier adapter for attaching a water purifier to either a male screw type faucet or a female screw type faucet. Is formed with a flange portion 22 of the upper tube body 18 having a male screw 24 corresponding to a female screw of a female screw type faucet formed on one outer peripheral surface with the collar portion 22 as a boundary and a male screw 26 for coupling formed on the other. And a bottomed cylindrical portion 20a having an inner diameter formed with an internal thread 32 corresponding to the male thread of the male screw type faucet and capable of being screwed into the male thread 26 for coupling, and communicating with the bottom of the cylindrical portion 20a. Then, the lower tubular body 20 has a connecting pipe portion 20b for connecting to a connecting port of a water purifier integrally formed with the tubular portion 20a.

[0005]

[Action]

 If you are installing the water purifier on a male screw type faucet that does not match the diameter, remove the foam cap from this faucet. On the other hand, the upper pipe 18 is removed from the lower pipe 20, the female screw 32 of the lower pipe 20 is screwed into the male screw of the male screw type faucet, and the connection pipe part 20b of the lower pipe 20 is connected to the water purifier. Insert the water purifier into the male screw type faucet. Also, when installing a water purifier on a female screw type faucet whose diameter does not match, remove the foam cap from this faucet. Next, with the upper pipe body 18 and the lower pipe body 20 still connected, the male screw 24 of the upper pipe body 18 is screwed into the female screw of the female screw type faucet, and the connecting pipe portion 20b of the lower pipe body 20 is connected. Insert the connection port of the water purifier.

【Example】

 Hereinafter, the configuration of the present invention will be described in detail with reference to the embodiments shown in the accompanying drawings. Reference numeral 16 is an adapter according to the present invention, which is composed of an upper tube body 18 and a lower tube body 20. A flange portion 22 for a spanner is integrally formed at an intermediate portion of an outer peripheral surface of the upper tube body 18, and a fitting flat surface is formed on the flange portion 22 for engaging the spanner and stopping the sliding. ing.

On the outer peripheral surface of the upper tube body 18, male screws 24 and 26 are vertically formed with the collar portion 22 as a boundary. The male screw 24 is formed to fit the female screw 15 of the female screw type faucet 14 shown in FIG. 3C, to which the foam cap 12 is detachably attached to the female screw 15.

The lower tubular body 20 is integrally formed with a bottomed tubular portion 20a and a tubular connecting pipe portion 20b having an inner and outer diameter smaller than that of the tubular portion 20a. Knurled eyes for rotating manual operation are engraved on the outer periphery of the tubular portion 20a. The upper end of the connection pipe portion 20b is open at the center of the bottom portion of the tubular portion 20a perpendicular to the axial direction.

A rubber packing 28 is arranged on the bottom portion. The connection pipe portion 20b is formed so as to fit the faucet connection opening 30a of the water purifier 30 shown in FIG. A female thread 32 corresponding to the male thread 26 of the upper tubular body 18 and the male thread 6 of the male screw type faucet 10 is formed on the inner peripheral surface of the tubular wall of the tubular portion 20a.

Reference numeral 34 is a rubber packing. Next, the operation of this embodiment will be described. In the case of the round faucet 2 with a swollen tip shown in FIG. 3A or the straight faucet 4 shown in FIG. 3D, the connection port 30a of the water purifier 30 is inserted into the faucets 2 and 4, and the water purifier 30 is inserted. Attach directly to faucets 2 and 4.

In the case of the structure shown in FIG. 3B in which the foam cap 8 is screwed into the male screw 6 of the faucet 10, the foam cap 8 is first removed from the faucet 10. Next, the upper pipe body 18 and the lower pipe body 20 are removed from each other, and the female screw 32 of the tubular portion 20a of the lower pipe body 20 is screwed into the male screw 6 of the faucet 10 to connect the lower pipe body 20 to the faucet 10. To do.

Next, the connection port 30a of the water purifier 30 is inserted into the connection pipe portion 20b of the lower pipe body 20. In the case of the structure shown in FIG. 3C in which the foam cap 12 at the tip is screwed into the female screw 15 of the faucet 14, the foam cap 12 is first removed from the faucet 10.

Next, in a state where the female screw 32 of the lower pipe body 20 is screwed into the male screw 26 of the upper pipe body 18 and the two are hermetically coupled by the rubber packing 28, the male screw 24 of the upper pipe body 18 is connected. , Screw into the female screw 15 of the faucet 14 to connect the adapter 16 to the faucet 14. Next, the connection port 30a of the water purifier 30 is inserted into the connection pipe portion 20b of the adapter 16.
