Inlet valve with a shortened lifting lever and a method of shortening the lifting lever of the inlet valve
First Claim
1. A method of shortening a lifting lever mechanism of an inlet valve, comprising:
- providing the inlet valve comprisinga main body having defined therein compression hole and a waterway passage;
a sealing pad;
a float that surrounds the main body and is movable up and down around the main body; and
the lifting lever mechanism that is rotatably connected to the main body of the inlet valve; and
shortening the lifting lever mechanism by configuring a shortened lifting lever mechanism that comprises at least two stages of levers, that each have a fulcrum, respectively, and that include a first stage lever and a last stage lever that are connected in a driving way one by one,wherein the float is coupled to the first stage lever of the shortened lifting lever mechanism and forms a dynamic body to drive the shortened lifting lever mechanism to move,wherein the sealing pad is assembled to the last stage lever of the shortened lifting lever mechanism, so that the sealing pad opens or closes the compression hole of the main body of the inlet valve when the float moves up and down to drive the shortened lifting lever to move, andwherein each of the lever stages of the at least two lever stages has a respective length of arm of force and a respective length of arm of resistance, and wherein the respective length of arm of force is longer than or equal to the respective length of arm of resistance, respectively, andwherein the first stage lever and the last stage lever are respectively rotatably connected to the main body of the inlet valve, the last stage lever is disposed between the first stage lever and the main body of the inlet valve, and the first stage lever is connected to the last stage lever in a driving way.

Abstract
An inlet valve having a shortened lifting lever mechanism includes a main body having defined therein a compression hole and a waterway passage; a sealing pad; a float; and a shortened lifting lever mechanism that is rotatably connected to the main body, that comprises at least two lever stages each having a fulcrum, respectively, and that include a first stage lever, and a last stage lever that are connected in a driving way. The float is coupled to the first stage lever so that a dynamic body is formed to drive the shortened lifting lever mechanism to move. The sealing pad is assembled to the last stage lever so that the sealing pad opens or closes the compression hole with the movement of the shortened lifting lever mechanism when the float moves up and down. A method of shortening a lifting lever mechanism of an inlet valve is also disclosed.
