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.

A check assembly of a sprinkling head for a kitchen cabinet, the sprinkling head being a hollow L-shaped tube member, having a sprinkling opening at a free end of a short pipe section of the sprinkling head, a controlling depression grip being connected to a bight section of the sprinkling head, a controlling valve stem being disposed in a long pipe section of the sprinkling head, an upper end of the valve stem protruding out of the bight section and two watertight washers being fitted around the valve stem, one of the watertight washers abutting against peripheral wall of a water outlet formed in the sprinkling head, a lower end of the valve stem being fitted with a conic spring and the check assembly and a free end of the long pipe section being connected with a water hose, whereby 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, said check assembly being characterized in that: 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 being a cylindrical body having a lower opening, a cross-like rib being formed on a top face of the valve seat and a hollow post extending downward and upward from a center of the cross-like rib, an annular flange being formed on outer wall of a middle section of the valve seat, one end of the pin member being disposed with a pin head and the other end thereof being a pin post, an upper face of the check pad being formed with a large sink and a lower face thereof being formed with a small sink, the two sinks being communicated by a central through hole, the pin post of the pin member being upward passed through the through hole to fit through a spring into the hollow post of the valve seat with the pin head engaged in the small sink of the check pad, the flange of the check valve seat being engaged with the water inlet seat and molten and sealed at an end of the water inlet seat by high frequency wave, an annular lip being formed in a water inlet of the water inlet seat, whereby the conic check pad is plugged into the water inlet and engaged with the annular lip, the water inlet seat having an outer thread section for engaging with inner thread of the long pipe section of the sprinkling head, the free end of the long pipe section being further engaged with the water hose; and when the depression grip is depressed and the water flows through the water hose into the sprinkling head, the water first passed through the check assembly to upward push the conic check pad and compress the spring, permitting the water to enter the sprinkling head to be sprinkled out from the sprinkling opening and after the water pressure disappears, the check pad is pushed back to abut against the annular lip of the water inlet by the restoring force of the spring so that 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.
