ABSTRACT:
A check assembly of a sprinkling head for a kitchen cabinet. The sprinkling head is a hollow L-shaped tube member having a sprinkling opening. A controlling depression grip is connected to a bight section of the sprinkling head. A controlling valve stem is disposed in the sprinkling head. An upper end of the valve stem protrudes out of the bight section and two watertight washers are fitted around the valve stem to abut against peripheral wall of a water outlet formed in the sprinkling head. A lower end of the valve stem is fitted with a conic spring and check assembly and an end of the sprinkling head is connected with a water hose. By means of depressing the depression grip, the controlling valve stem is lifted or lowered to control the sprinkling of the water flow from the sprinkling opening. The check assembly includes a check valve seat, a plastic pin member fitted in the valve seat, a rubber-made soft conic check pad fitted around the pin member and a water inlet seat fitted with the valve seat. The check valve seat is engaged with the water inlet seat and molten and sealed at an end of the water inlet seat by high frequency wave. The water inlet seat is engaged with the sprinkling head which is further engaged with the water hose. In case an accident takes place with the sprinkling head placed in a sink after washed, the dirty water is prevented from flowing back into the water hose due to syphon effect.
