20110303702 | Liquid spray head assembly - A spray head assembly includes a push member, a piston rod, a spring, a seal member, a link, a movable member, a cylinder and a resilient valve. The link includes multiple axial slots defined in an outer surface thereof so that no surplus and rough material is left during manufacturing. The spiral valve effectively responses the operation of the spray assembly to seal or open the path in the cylinder. | 12-15-2011 |
20120080454 | Spray head assembly - A spray head assembly includes a head, a main tube, a link, a piston, a reception member, a mount piece and a spring. The parts made of metal such as the spring is isolated from the liquid to ensure that the liquid is not affected by the metal. The main tube can be stopped by the extension portion of the mount piece so as to adjust the length of the mount piece to control the travel distance of the main tube so as to control the volume of each spray. | 04-05-2012 |
20120080539 | Foam spray head assembly - A foam spray head assembly includes a head, a first piston unit, a valve unit, a link, a second piston unit, a cylinder, a resilient member and a resilient valve. The valve unit is directly connected to the head to allow the valve unit to receive the pressing force of the head to quickly respond in the form of reciprocating motion. The parts made of metal such as the spring is isolated from the liquid to ensure that the liquid is not affected by the metal. | 04-05-2012 |

20120292347 | Push-type nozzle assembly - A push-type nozzle assembly includes a main tube, a valve, a suction unit and a push unit. The suction unit includes a push rod, a connection rod, a block and a seal sleeve. A spring is mounted between the seal sleeve and the push rod. The spring provides a force to move the block and the connection rod back and forth between the closed position and an open position. Because the spring is located outside of the push rod, the spring does directly contact the liquid which is avoided from being chemically changed. | 11-22-2012 |
20120305604 | Nozzle assembly - A nozzle assembly includes a main tube, a mounting unit, a valve, a suction unit, a resilient unit and a push unit. The suction unit includes a push rod, a connection rod and a block. The resilient unit is located outside of the push rod so that the resilient unit does not directly contact the liquid which is avoided from being chemically changed. The main tube, the mounting unit and the suction unit are modularized and can be assembled as desired so that the stocking pressure is reduced. | 12-06-2012 |
20140054321 | FOAM SPRAY HEAD ASSEMBLY - A foam spray head assembly includes a press head connected to a cap, a netted tube, a valve member, a main tube, a piston unit, a link unit, a resilient member, a cylinder unit and a valve. The netted tube is connected to the valve member. An outlet is defined between the first link of the link unit and the first tube. An inlet is defined between the second link of the link unit and the protrusion of the piston unit. The resilient member is mounted to the second tube and contacts the flange of the second tube. The first piston of the cylinder unit is movable in the first cylinder to form a sealed second chamber. The second piston of the cylinder unit is movable in the second cylinder to form a sealed third chamber. The valve is located in the passage of the second cylinder. | 02-27-2014 |
20140084027 | LOTION SPRAY HEAD ASSEMBLY - A spray head assembly includes a press head, a seal member, a push tube, a piston unit, a resilient member, a cylinder unit, a valve and a mount. The press head has an annular face and a first locking portion. The seal member has an inner tube portion and a water-proof portion. The push tube is connected to the press head and has a second locking portion. The cylinder unit has a piston and a main rod respectively connected to the push tube. The main rod has a seal part and the cylinder unit has a narrowed portion. When the press head is pressed, the first locking portion and the second locking portion are positioned and the press head is easily assembled. The narrowed portion and the seal part, and the top of the inner tube portion and the annular face are engaged with each other to prevent from leakage. | 03-27-2014 |
20140199195 | CYLINDER ASSEMBLY AND DISPENSER PUMP USING THE SAME - The cylinder assembly includes a first body, a second body and a coupling mechanism. The first body is of a tubular shape and has a valve set at a bottom end thereof. The valve set includes a valve, an elastomer and a passage. The second body has a ring with an outline fitting the valve. | 07-17-2014 |
