DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] With reference to FIGS. 2-5, a rotary control structure for a water valve according to a preferred embodiment of the present invention comprising:

[0018] A body 1, a control shaft 2, a connection disk 3, a positioning disc 4, a guide disc 5, and a stop ring 6.

[0019] Referring to FIGS. 2-4, the body 1 includes a drive section 11 formed in a hexagon shape on a top of the body 1 and configured to connect with a hand tool, a threaded section 12 formed below the drive section 11 and configured to screw with a faucet so that the hand tool operates the drive section 11 to screw the body 1 with the faucet. The body 1 further includes a through orifice 13 defined on a central portion thereof and configured to accommodate the control shaft 2, wherein the body 1 further includes a receiving space 14 defined below and being coaxial with the through orifice 13, wherein a diameter of the receiving space 14 is more than the through orifice 13, such that the receiving space 14 accommodates the connection disk 3, the positioning disc 4, the guide disc 5, and the stop ring 6. The body 1 further includes an outlet 15 defined on an outer wall of an intermediate section of the body 1 so as to guide water to a water outflow end of the faucet, wherein a lower end of the body 1 is in connection with a water inflow end of a water pipe. Furthermore, the body 1 includes a washer 16 fitted on a lower end of the threaded section 16 so as to stop a water leakage, when the body 1 is screwed with the faucet.

[0020] As shown in FIGS. 2-4, a difference of the control shaft 2 from a conventional control shaft comprises: the through orifice 13 of the body 1 having a limitation slot 131 defined on a wall of the through orifice 131, the control shaft 2 being cylindrical and including a fixing portion 21 formed on an intermediate section of the control shaft 2 and a C-retainer 22 fitted on the fixing portion 21, such that the control shaft 2 is pushed downward to the body 1 and is connected with the body 1 by using the C-retainer 22. The control shaft 2 further includes multiple O-rings 24 fitted on the fixing portion 21 so as to stop the water and to matingly contact with the drive section 11.

[0021] As shown in FIGS. 2, 4, and 5, the connection disk 3 is accommodated in the receiving space 14 and includes a coupling groove 31 so as to retain with an insertion 23 of a bottom of the control shaft 2, when the control shaft 2 is connection with the body 1, and the control shaft 2 drives the connection ring 3 to revolve after being rotated. As illustrated in FIGS. 4-5, the connection disk 3 includes a rib 32 extending from a bottom thereof so as to urge the positioning disc 4 to rotate.

[0022] The positioning disc 4 is coupled with the connection disk 3, wherein the positioning disc 4 includes an actuation recess 41 defined on a top thereof and corresponding to the rib 32, and the positioning disc 4 includes a sector cutout 42 formed on a bottom thereof and configured to correspond to a fan-shaped aperture 51 of the guide disc 5, wherein when the sector cutout 42 corresponds to and communicates with the fan-shaped aperture 51, the water flows into the fan-shaped aperture 51 via the sector cutout 42; and when the sector cutout 42 does not communicate with the fan-shaped aperture 51, the water stops flowing into the fan-shaped aperture 51 from the sector cutout 42.

[0023] The stop ring 6 is mounted below the fan-shaped aperture 51 and is configured to limit the connection disk 3, the positioning disc 4, and the guide disc 5 in the receiving space 14 and to gather the water, thus avoiding the water leakage.

[0024] Since the positioning disc 4, the guide disc 5, and the stop ring 6 are well-known art, further remarks are omitted.

[0025] In assembly, as shown in FIG. 4, the connection disk 3, the positioning disc 4, and the guide disc 5 are accommodated in the receiving space 14 of the body 1. The control shaft 2 is pushed downward to and is connected with the body 1 by using the C-retainer 22, then the insertion 23 of the control shaft 2 is retained with the coupling groove 31, thus connecting the rotary control structure easily and quickly.

[0026] With reference to FIGS. 2-4, the connection disk 3 includes a wear-resistant ring 7 arranged on a top thereof to abut against a top of the receiving space 14 and to reduce damage of the connection disk 3, thus prolonging a service life of the connection disk 3.

[0027] While the preferred embodiments of the invention have been set forth for the purpose of disclosure, modifications of the disclosed embodiments of the invention as well as other embodiments thereof may occur to those skilled in the art. Accordingly, the appended claims are intended to cover all embodiments which do not depart from the spirit and scope of the invention
