The control valve 1 and the faucet 5 can be connected to each other by screwing with a drain port 51 provided with a not shown). On the other hand, in the present embodiment, the connecting portion 113 has inner and outer screws at the same time, but in some cases, only one of the inner and outer screws may be provided, and the outer screw of the connecting portion may be connected to the outer periphery of the annular portion 112 The connecting portion 113 may not be provided.

In the first embodiment of the present invention, the drainage device 12 of the control valve 1 is a cylinder having an opening at one end and closed at the other end. The drainage device 12 includes a body 121 and a bottom portion 122. And the inner diameter of the body 121 is equal to the outer diameter of the annular portion 111 of the connector 11, so that a part of the body 121 can be fitted into the annular portion 111 of the connector 11. In addition, the outer peripheral surface of the body 121 is further provided with a number of grooves 1211 along the vertical direction, whereby the frictional force between the drainage tool 12 and the user's finger can be increased. The tool 12 can be easily rotated. In addition, the body 121 may be provided with a handle 1213 along the radial direction of the body 121, so that the user can easily rotate the drainage device 12. Moreover, you may provide the routing parts 114 and 124 in the outer surface of the connection tool 11 and the drainage tool 12, and if it does so, the connection part 11 and the drainage tool 12 can be drawn around by a tool (for example, spanner etc.), thereby The connecting portion 11 can be closely screwed to the drain 51 of the faucet 5 and the drainage tool 12.

Next, a second embodiment of the present invention will be described with reference to FIGS. 2B, 3C, and 3A. The water stopper 13 includes a valve body 131 and a packing 132, and the valve body 131 is provided at the center of the bottom 122 of the drainage tool 12. In particular, in this embodiment, the valve body 131 and the drainage tool 12 are integrally formed. Of course, the valve body 131 and the drainage tool 12 may be separated and integrated by a tightening method. On the other hand, the upper end of the valve body 131 is provided with an external screw, and a through hole 1111 through which the connector 11 is inserted is opened. The outer diameter of the upper end of the valve body 131 is the same as that of the through hole 1111. Two water supply grooves 133 are further provided at the upper end of the valve body 131 that are smaller than the inner diameter, and the water supply groove 133 extends over the entire length of the external screw along the axial direction of the valve body 131, and The external screw provided at the upper end of the valve body 131 is partitioned by the water supply groove 133 and becomes discontinuous. However, the number of the water supply grooves 133 is not limited to two. One or more water supply grooves 133 are provided at the upper end of the valve body 131, and, for example, three water supplies are provided at the upper end of the valve body 131 as shown in FIG. A groove 133 may be provided. Further, a space constituted by the water stopper 111, the annular portion 112, the valve body 131, and the drainage tool 12 and the water supply groove 133 form a water supply 123, and a water supply 123 is provided at the bottom of the drainage tool 12. Many drain holes 1221 communicating with the outside are opened. A C retaining ring 14 is assembled to the upper end of the valve body 131. As shown in FIG. 3A, when the user rotates the drainage tool 12 to the first position, the C retaining ring 14 is stopped by the water stop portion 111 of the coupling tool 11, and then the drainage tool 12 is excessively rotated and the coupling tool. 11 will not leave. Of course, a member having the same function as the C retaining ring 14 may be provided at the upper end of the valve body 131. For example, after the valve body 131 is screwed into the through hole 1111, a rivet portion (not shown) is formed at the upper end of the valve body 131. )), The drainage tool 12 will not be detached from the connector 11.

Further, the valve body 131 further has a convex edge 1311 provided under the external screw provided at the upper end of the valve body 131, and the packing 132 is an external screw provided at the upper end of the valve body 131. It is fitted below and fixed on the convex edge 1311. As shown in FIG. 3A, when the user wants to take water, first, the drainage tool 12 is rotated to the first position, and the water in the faucet 5 is discharged from the drainage hole 1221 to the outside via the water supply 123. Is done. As shown in FIG. 3B, when the user wants to stop water, first, the packing 132 is brought into close contact with the water stopper 111 and the convex edge 1311 by rotating the drainage device 12 to the second position. 123 is closed. In the present embodiment, a washer is provided between the upper surface of the coupling portion 113 of the coupling tool 11 and the drainage port 51 of the faucet 5, and the outer surface of the annular portion 112 of the coupling tool 11 and the drainage tool 12. An O-ring is provided between the inner surface of the body 51 and the body 51 so that water does not bypass and flow out to the outside.

Moreover, the use state of Example 1 of this invention is demonstrated, referring FIG. 4A and 4B. In the control valve 1, a protrusion 1121 is further provided on the outer peripheral surface of the annular portion 112 of the connector 11, and a control slide groove 1212 is provided obliquely on the inner surface of the body 121 of the drainage device 12. The protrusion 1121 is slidable in the control slide groove 1212 so as to be regulated at both ends of the control slide groove 1212. The protrusion 1121 and the control slide groove 1212 prevent the drainage tool 12 from being excessively rotated and destroying the packing 132, or preventing the drainage tool 12 from escaping. On the other hand, a protrusion 1121 may be provided on the inner surface of the body 121, and a control slide groove 1212 may be provided on the outer surface of the annular portion 112. According to such a configuration, the same effect as described above can be achieved.

Next, a use state of the second embodiment of the present invention will be described with reference to FIGS. 5A and 5B. The difference between the control valve 2 according to the second embodiment of the present invention and the control valve 1 according to the first embodiment of the present invention is that the valve body 231 is screwed to the bottom 222 of the drainage tool 22 and the coupling tool. 21 has a locking portion 214 provided around a through-hole (see reference numeral 1111 in FIG. 2A). The locking portion 214 has a stepped shape, and a convex portion 2311 is provided at the upper end of the valve body 231. The contour of the convex portion 2311 corresponds to the contour of the locking portion 214, and the packing 232 is provided between the locking portion 214 and the convex portion 2311. When the user wants to take water, as shown in FIG. 5A, first, the drainage tool 22 is rotated to the first position, and the water in the faucet 5 is discharged from the drainage hole 2221 to the outside via the water supply 223. Is done. Further, as shown in FIG. 5B, when the user wants to stop the water, first, the packing 232 is brought into close contact with the convex portion 2311 and the locking portion 214 by rotating the drainage tool 22 to the second position. 223 is closed.

In the second embodiment of the present invention, the locking portion 214 has a staircase shape, but of course, other shapes may be used, as shown in FIGS. 6A and 6B, for example, according to the third embodiment of the present invention. The locking portion 314 of the control valve 3 has a funnel shape, and the contour of the convex portion 3311 of the valve body 331 corresponds to the contour of the locking portion 314. In the second and third embodiments, the packings 232 and 332 are provided between the convex portions 2311 and 3311 and the locking portions 214 and 314, respectively. Of course, as shown in FIG. The packings 232, 332 may be fixed to the convex edges 2222, 3222 by fitting the packings 232, 332 under the external screws provided at the upper ends of 231, 331. Then, the control valve can be opened and closed by rotating the drainage tools 22 and 32 between the first position and the second position.

Reference is now made to FIG. The control valve further includes a foam generator 15.
