This disclosure relates to a showerhead including a body, a stationary plate, a spring, and an insert fitting member. The body has an upper body and a lower body. The upper body and the lower body form an accommodation space. A water inlet for supplying water into the accommodation space is provided at the upper body, and a plurality of water outlets for spraying water from the showerhead are provided on the lower body. The stationary plate is located in the accommodation space and movable up and down in the accommodation space along a direction of the water flow. The spring is disposed between the stationary plate and the lower body, for applying a force to the stationary plate away from the lower body. The insert fitting member is fitted to the stationary plate. The position of the insert fitting member corresponds to the plurality of water outlets on the lower body. When the water is supplied, the stationary plate moves to a lower position under the action of water pressure, and the insert fitting member partially closes the water outlet to form a drizzle-type spray; and when the water is turned off, the spring pushes the stationary plate back to the upper position, and the water outlet plug leaves the water outlet.

A pressurizable fluid container apparatus, system and method of use.

A dynamically-controllable spray nozzle, and associated control system and methods of use, has applicability in agricultural spraying and in other processes and devices in which spray nozzles are used. In an embodiment, a deformable nozzle may be compressed by one or more actuators to alter a nozzle’s exit orifice in a continuously variable manner.

A spray gun having a gun body is provided. A duct extends in the gun body between an inlet mouth and a main outlet mouth. The gun body has a handle, the inlet mouth located in the handle, extending along a handle axis; a barrel, the main outlet mouth formed in the barrel, extending along a barrel axis; and an adjustment element extending onto the barrel around and parallel to the barrel axis. The adjustment element has a central cavity accommodating the barrel and a secondary outlet mouth. The adjustment element is axially movable between a retracted position and a forward position, in which the adjustment element is advanced axially cantilevered on the barrel, with the secondary outlet mouth axially distal to the main outlet mouth, defining, within the central cavity, an adjustment chamber filled with water exiting the main outlet mouth to flow through the secondary outlet mouth.

A fluid dispenser having an accumulator and a discharge head. The discharge head is secured to a base unit of the dispenser, which base unit includes a fluid accumulator. The discharge head has a housing displaceable relative to the base unit for actuating the dispenser. The discharge head has an inlet through which fluid travels from the fluid accumulator into the discharge head, and a discharge opening through which the fluid is delivered into the atmosphere. A swirling chamber having an inlet channel is provided between the fluid inlet and the discharge opening so that inflowing fluid is provided with a swirl which forms a spray stream when exiting the discharge opening. The swirling chamber is switched between a first and a second configuration by changing the geometry of its walls and/or the inlet channel.
