Double flow control mechanism of a soft touch drain valve and a double flow control method thereof

A double flow control mechanism of a soft touch drain valve, comprising

• a base,
• a float component and
• a starting component,
• the base is assembled with a valve body,
• the base is disposed with a drainage opening (11),
• the float component can move relative to the base to open and close the drainage opening, wherein;
• the starting component comprises a first starting switch and a second starting switch,
• the float component is movably assembled to the valve body and connected to the starting component in driving way,
• the float component is disposed with a flowing passage,
• the flowing passage connects the inner side and the outer side of a float chamber of the float component,
• the starting component controls the size of the flowing passage;
• operating the first starting switch can drive the float component to rise up, the starting component opens a smaller flowing passage, the resultant force of the float component is influenced by the smaller flowing passage so as to drain a first drainage volume of water;
• operating the second starting switch can drive the float component to rise up, the starting component opens a larger flowing passage, the resultant force of the float component is influenced by the larger flowing passage so as to drain a second drainage volume of water.
