The device (100) may include a printing substance dispensing nozzle (110) movable between a first position with an orifice (126) of the printing substance dispensing nozzle (110) facing an internal face of the valve body (108) and a second position with the orifice (126) of the printing substance dispensing nozzle (110) facing the printing substance transfer aperture (122). The device (100) may include a dispensing-side gasket material (132) slide-able through the printing substance transfer aperture (122) when moving the printing substance dispensing nozzle (110) between the first position and the second position.

A spray gun shower head includes a shower body, a switching body and a reset assembly. The shower body has a water intake path and at least one first and second water outflow paths. The switching body is movable between first and second switch positions and configured to switch the water intake path to be communicated with the first or second water outflow path. The reset assembly includes at least one reset member and a push block. The second water outflow path is hidden in the shower body through a cover. The cover is pushed against by an opening structure to be opened. The reset member is disposed on the shower body, and one end thereof cooperates with the push block. The push block is disposed on the switching body and rotates toward the second switch position along with the switching body to press against the reset member.

An adjustable nozzle having a nozzle body having an inlet section with an inlet opening, an outlet section with an outlet opening, and a fluid flow path extending from the inlet opening to the outlet opening; a spray restrictor segment located in the outlet section; and an actuator that displaces the spray restrictor segment toward and away from a center of the fluid flow path, thereby varying a pattern of fluid flowing from the fluid flow path through the outlet opening.

An electromechanical emitter of fragrances/scents includes a blowpipe constructed in elastomeric material, which has an open edge layered by a latch valve and the other edge, closed, contains a magnet. In the internal side of the blowpipe, there is an absorber element with the fragrance or scent and an electric reel curly in its external side. When the reel receives alternated electric pulses, it generates a form of magnetic inductance shaping an alternated magnetic field attracting and repelling the magnet, making the blowpipe to enter into a frequency where a greater range of movement and greater volume of air in motion through the internal side of the system can be observed, enhancing the scent during the blowpipe vibration.

A configurable nozzle includes a nozzle body having a reception chamber configured to receive an application mixture. The nozzle body includes a nozzle orifice. At least one orifice assembly is coupled with the nozzle body, the at least one orifice assembly includes an orifice plate movably coupled with the nozzle body. The orifice plate extends along at least a portion of the nozzle orifice, and movement of the orifice plate changes one or more of the size or shape of the nozzle orifice. An orifice actuator is coupled with the orifice plate, and the orifice actuator is configured to move the orifice plate.

An example of a device (100) may include a valve body (108); a printing substance dispensing nozzle (110) rotatable within the valve body (108) between a sealed orientation and a dispensing orientation; and a locking rod extending through a locking rod window (146) in the valve body (108) and into a locking rod channel (144) in the printing substance dispensing nozzle (110), wherein the locking rod is movable within the locking rod window (146) between a first position, fixing the printing substance dispensing nozzle (110) in the sealed orientation, and a second position allowing rotation of the printing substance dispensing nozzle (110) to the dispensing orientation.

A jetting valve with two stage calibrating structures is disclosed, the jetting valve includes: a casing having an accommodating space; a piezoelectric actuating unit disposed on one side of the accommodating space; a spraying unit disposed on the other side of the accommodating space; a displacement amplifying element is arranged at the bottom of the accommodating space and leans against on the spraying unit, the bottom end of the piezoelectric driving unit is in contact with the displacement amplifying element; a sensing unit is arranged on the periphery of the displacement amplifying element to sense the movement of the spraying unit; a control unit, connected to the sensing unit and the piezoelectric actuating unit, adjusting the voltage supplied to the piezoelectric driving unit according to data obtained by the sensing unit; and a liquid supply unit connected to the spraying unit. In accordance with the present invention, a dispenser may be corrected its starting position for dispensing by large-range and small-range correction, and achieve the effect of rapid and accurate spraying calibration.

A spray gun shower head includes a shower body and a waterway closing element. The shower body is disposed with a first water passageway communicated with a water intake opening and a first water outflow opening (12), and a second water passageway communicated with the water intake opening and a second water outflow opening. The second water passageway is configured to spray the spray gun water. The waterway closing element is rotatable to a second switch position to open the second water passageway and close the first water passageway while driving an opening structure to push against a cover to be flipped up, so that the second water outflow opening hidden in the shower body by the cover sprays the spray gun water.
