A sprinkler head for attaching to a stem of a sprinkler, the sprinkler head having a round or polygonal shaped perimeter and comprising a directional nozzle array on the perimeter of the sprinkler head, the directional nozzle array comprises a single nozzle or a stack of nozzles each nozzle having an orifice facing a specific radial direction; the directional nozzle array being in fluid connection with a conduit through the stem for providing irrigation in the radial direction; wherein the directional nozzle array is provided with a dedicated regulator independently configurable by the user for regulating water flow in the specific radial direction over a range from zero when fully closed to a maximum range when fully open.

An applicator comprises a housing having a liquid input, a pump, a motor, and a power source; a trigger for providing selective control over the pump; a wand hingedly connected to the housing; and a nozzle coupled to the wand for discharging liquid from the applicator. The nozzle and the liquid input are in fluid communication via the pump and various conduits of the applicator.

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 multipurpose wheel-washing apparatus includes a wheel-washing unit including an upper frame provided with a plurality of rollers on which wheels of a vehicle are to be rotatably seated, and injection nozzles configured to inject high-pressure washing water onto the wheels seated on the rollers; and a lower frame provided with a water tank located below the upper frame so as to collect falling waste/turbid water; a water storage unit configured to store washing water to be supplied to the injection nozzles; a purification unit configured to receive and purify the waste/turbid water from the water tank and then send purified water to the water storage unit; and a blowing unit disposed on an exit side of the wheel-washing unit so as to blow air and provided with spray nozzles for selectively spraying water in a particulate form. Accordingly, environmental pollution can be significantly reduced.

An aquarium includes a container that contains a liquid. A spout includes a first leg that extends along a first axis from an inlet positioned in a bottom portion of the aquarium space to a bend, and a second leg that extends along a second axis from a flow aperture formed adjacent the bend to an outlet. The spout is arranged to direct a portion of the liquid from the inlet to the outlet. A cap is coupled to the spout and is rotatable between a first position and a second position. The cap includes a seal element positioned to form a seal between the cap and the spout, and a flow control member fixedly attached to the cap and sized to completely block the flow aperture when the cap is in the first position and to completely uncover the flow aperture when the cap is in the second position.

An inflatable sprayhead includes a main body made of an elastic material. The main body includes an inflatable portion and an output portion. The inflatable portion and the output portion are coupled. The inflatable portion has a first chamber inside, and the inflatable portion is changeable between an inflated state and an uninflated state by inflating or deflating the first chamber. The output portion has a second chamber and an output surface, which communicates with the second chamber. The main body includes an isolation portion that is located between the inflatable portion and the output portion, wherein the first chamber and the second chamber are separated by the isolation portion. Thus, when the main body is in the uninflated state, a volume of the main body could be reduced. Additionally, the main body that is foldable and flexible facilitates storage.
