Patent ID: 8453667

Claim:
A cleaning water supply device comprising: a mixing unit including a channel assembly and a circular valve member, wherein the channel assembly includes an inlet channel, an outlet channel, a through channel between the inlet and the outlet channels, and at least one intake communicating with the through channel; when a water flow flows into the outlet channel from the inlet channel, a vacuum attraction generates in the through channel; the valve member is installed in the through channel and includes a flexibly circular wing formed therein to abut against and close the through channel so that the intake is stopped communicating with the inlet channel and the outlet channel, and when the vacuum attraction generates in the through channel, the inlet and the outlet channels are opened; a storing unit connected with the channel assembly of the mixing unit and including a chamber to receive a cleaning fluid and an output tunnel communicating with the chamber and the intake, thus flowing the cleaning fluid outward; the cleaning fluid in the chamber being drawn into a connection of the inlet channel and the outlet channel along the output tunnel, the intake, and the through channel after the water are turned on, thereafter the cleaning fluid mixing with the water flows to form a cleaning water; wherein the channel assembly includes a body and a plug member; the body is provided to define one part of the inlet channel, one part of the outlet channel, and one first hole to define one part of the intake and a first groove; the plug member is installed in the first groove of the body to define the through channel, one part of the inlet channel, one part of the outlet channel, and at least one second hole, the second hole and the first holes are combined to define the intake; wherein the plug member includes a first plug and a second plug, both of which are fixed in the first groove of the body; the first plug includes a first bore axially passing therethrough to define one part of the inlet channel; the second plug includes a second bore axially passing therethrough to define one part of the outlet channel and at lease one recess formed on a peripheral top surface thereof to define the intake with the first plug; between the first plug and the second plug is defined the through channel; wherein the second plug includes a plurality of projections extending from the peripheral top surface thereof and spaced apart from each other, each two adjacent projections is used to define the recess, and between the projection and the first groove of the body is formed a circular path so that each two second holes are in communication with each other.
