A trigger dispenser device (1) envisages a secondary liquid aspiration duct (50) in communication with the dispenser duct, and a primary liquid aspiration duct (8) in communication with the container, off-axis with each other. Between these, a joining compartment (64) is provided communicating upstream with the primary liquid aspiration duct (8) and communicating downstream with the secondary liquid aspiration duct (50) to form the fluidic connection between them. In particular, the container (C) is of the type with built-in suction pipe.

A system for applying a lavage fluid to a surface, the system having a body configured to house a lavage fluid and at least two interchangeable application members configured to be in fluid communication with the body, wherein the at least two interchangeable application members includes a first application member and a second application member, the first application member being configured to dispense the lavage fluid with a first fluid flow force and/or first fluid flow pattern, and the second application member being configured to dispense the lavage fluid with a second fluid flow force and/or second fluid flow pattern that is different from the first fluid flow force and/or fluid flow pattern, respectively.

A brushless car wash system includes a wash unit that washes upper surfaces of the vehicle. The height of the wash unit is adjusted based on the contour of the upper surfaces of the vehicle. Adjusting the height of the wash unit results in increased wash performance of the brushless car wash system.

A thermal regulation apparatus for pool water is an apparatus that is used to regulate the overall temperature of a pool in an efficient and cost-effective manner. The apparatus may include a water-jet adapter, a tee tubing connector, a valved spout, a valved drain, and an extension pipe. The water-jet adapter enables the apparatus to be connected to a water return jet and serves as the main water inlet of the apparatus. The tee tubing connector distributes the water inflow from the water-jet adapter to the valved drain and the extension pipe. The extension pipe guides the water inflow towards the valved spout. The valved spout serves as the main outlet for the apparatus and enables the cooling of the water outflow that is diffused back into the pool. The valved drain serves as a secondary outlet for the apparatus and helps control the water flow through the apparatus.

A spray device includes a controller, a mobile device, a spray tank, a multi-angle spray pipe structure and a nozzle. The controller is arranged on the mobile device and controls the movement of the mobile device. The spray tank includes a liquid reservoir. The multi-angle spray pipe structure is arranged on the spray tank and is communicated with the liquid reservoir. The nozzle is arranged on the multi-angle spray pipe structure. An inlet end plane is formed at an edge of an inlet end of the multi-angle spray pipe structure, an outlet end plane is formed at an edge of an outlet end of the multi-angle spray pipe structure, and the inlet end plane and the outlet end plane intersect to form an included angle.

A toilet assembly includes a toilet body and a nozzle system. The toilet body defines a toilet bowl and a rim area disposed along an upper edge of the toilet bowl. The rim area includes a flange defining an opening. The nozzle system includes a nozzle having a first end configured to be fluidly coupled to a water supply conduit and a second end fluidly coupled to the rim area. The second end defines an outlet formed at a compound angle. The connector assembly detachably couples the nozzle to the flange such that the nozzle extends through the opening.

Systems and methods are provided in which residual materials are removed from an interior surface of a drum or similar vessel at the end of a duty cycle. This is followed by application of a non-siliceous aqueous solution to the cleaned surface, which provides a durable low-friction coating to the interior wall of the rotating drum mixer throughout the following duty cycle or use.

A hand-held battery operated sprayer with a rotatable spray lance includes a spray lance assembly and a spray chamber. A motor, a pump, a shutoff valve, a suction hose assembly, a pump inlet hose, a pump outlet hose, a battery pack, and a conductor are disposed in the spray chamber. Water sequentially passes the suction hose assembly, the shutoff valve, the pump inlet hose, the pump, and the pump outlet hose, and flows out of the spray chamber. A rotary axle base is disposed at the front end of the spray chamber. A right-angled rotating shaft is movably connected in the rotary axle base. The rotating shaft is connected to the spray lance assembly. The pump outlet hose can reach a nozzle of the spray lance assembly through the rotating shaft.

A spray nozzle includes a transmission component and a fan blade assembly. The fan blade assembly is connected to the transmission component, and can rotate with respect to the transmission component to create a vacuum inside the fan blade assembly, so that the liquid to be atomized under atmospheric pressure can enter the fan blade assembly through the transmission component. The fan blade assembly can also drive the liquid in the fan blade assembly to rotate so as to atomize the liquid and eject it from the fan blade assembly. The liquid in the fan blade assembly rotates with the fan blade assembly. A sprayer includes a body and the spray nozzle.
