DETAILED DESCRIPTION

(6) With reference to FIGS. 2-5, a connection structure of a ball valve of a control valve for draining water out of a water sink according to a preferred embodiment of the present invention comprises: a body 1, a filtration cap 2, the ball valve 3, a handle bar 4, and a positioning ring 5.

(7) The body 1 is a hollow tube, and the body 1 includes a first connecting portion formed on a top thereof and configured to connect with the filtration cap 2, a second connecting portion 12 formed on a bottom of the first connecting portion 11 in a vertical direction of the body 1 and configured to accommodate the ball valve 3, a coupling portion 13 extending horizontally along the second connecting portion 12, and a fixing portion 14 formed on a bottom of the second connecting portion 12.

(8) Referring to FIGS. 2-5, the body 1 further includes a discharge orifice 15 defined on an end thereof opposite to the coupling portion 13 and configured to discharge wasted water, thus discharging water efficiently.

(9) As shown in FIGS. 2-5, the filtration cap 2 includes multiple filtering orifices 21 defined therein and configured to guide the wasted water into the body 1.

(10) As illustrated in FIGS. 2-5, the ball valve 3 is spherical and is received in the second connecting portion 12 from a bottom of the body 1, wherein the ball valve 3 includes a guide orifice 31 passing therethrough, a connection portion 32 extending along a horizontal direction of the guide orifice 31, wherein the handle bar 4 is inserted into the coupling portion 13 and connected with the connection portion 32, then the handle bar 4 is screwed by a screw so that the ball valve 3 is engaged by the handle bar 4 to be turned on/off.

(11) With reference to FIGS. 2-5, the positioning ring 5 is received in the fixing portion 14 from the bottom of the body 1, and the ball valve 3 includes two washers 6 fixed on a top and a bottom of the ball valve 3, thus avoiding a water leakage of the body 1.

(12) Referring to FIGS. 2-5, the filtration cap 2 does not contact with the positioning ring 5 to cause an unflatness and a removal of the filtration cap 2. Also, the ball valve 3 and the positioning ring 5 are received in the second connecting portion 12 and the fixing portion 14 from the bottom of the body 1, thus connecting the ball valve 3, the positioning ring 5 and the body 1 easily. Preferably, the ball valve 3, the positioning ring 5 and the body 1 are detachable easily to obtain easy maintenance, and the ball valve 3 and the positioning ring 5 do not accommodate dirt.

(13) Thereby, the connection structure of a ball valve has advantages as follows: 1) The body 1 is machined easily. 2) The filtration cap 2 does not contact with the positioning ring 5 to cause the unflatness and the removal of the filtration cap 2. 3) The ball valve 3 and the positioning ring 5 are received in the second connecting portion 12 and the fixing portion 14 from the bottom of the body 1, thus connecting the ball valve 3, the positioning ring 5 and the body 1 easily. 4) The ball valve 3, the positioning ring 5 and the body 1 are detachable easily to obtain easy maintenance, and the ball valve 3 and the positioning ring 5 do not accommodate the dirt.

(14) While the first 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. The scope of the claims should not be limited by the first embodiments set forth in the examples, but should be given the broadest interpretation consistent with the description as a whole.
