A rotating sprinkler for irrigation is disclosed. The sprinkler can include a stator spaced upstream from a turbine to form a mixing region therebetween. The stator can define a primary flow path and a bypass flow path. The primary flow path is aligned relative to the plurality of blades so that water exiting the primary flow path traverses the mixing region and impinges on the plurality of blades at a first angle of attack. The bypass flow path is aligned relative to the primary flow path so that water exiting the bypass flow path intersects the water exiting the primary flow path in the mixing region to cause the water exiting the primary flow path to impinge on the plurality of blades at a second angle of attack. The sprinkler can further include a valve configured to regulate flow between the primary flow path and the bypass flow path.

A liquid discharge apparatus includes: a discharge head including a discharge portion configured to discharge a liquid; a cap configured to cap the discharge portion; a suction unit configured to suck an interior of the cap through a first fluid passage communicating with the interior of the cap in a state in which the cap caps the discharge portion; an open/close unit configured to open/close a second fluid passage communicating with the interior of the cap, the open/close unit being set in an open state when a negative pressure state of the interior of the cap, which is generated by suction by the suction unit, is canceled; and a filter arranged in the second fluid passage.

A mister kit provides components to assemble as needed and where needed misters of customizable configurations capable of on-site assembly, connectable with local business and residential water sources, and with the ability to be secured to nearby structures.

An essential oil reflux-type atomizer comprising the following structures: chassis, housing, atomization chamber, gas pump, gas tube, gas nozzle, oil nozzle, and filter atomization mechanism. The filter atomization mechanism is installed in the housing and has an upper filter and a lower filter. The essential oil atomizer can be improved efficiency and reduced noise level.

Disclosed is a flushing system for flushing debris from a sand trap of an irrigation system. The system includes a controlled valve fluidly coupled to a flush outlet of the sand trap. The valve is electronically controlled, such that when open and with the irrigation system running, water from the irrigation system entering the sand trap, flushes the sand trap via the valve. In one embodiment, the flush system comprises a valve connected to a purge outlet of the sand trap. A control unit in electrical communication with the valve and a sensor is associated with the control unit for sensing an operation of the irrigation system. The control unit is configured to control the valve to open or close based on input from the sensor relating to operation of the irrigation system, wherein when the valve is open fluid and/or debris can be purged from the sand trap.

A device for controlling the shape of discharged liquid comprises a liquid inlet end and a liquid outlet end. A passage allowing liquid to flow therein is disposed between the liquid inlet end and the liquid outlet end. The liquid outlet end comprises a liquid outlet in a rotationally symmetric shape. The liquid inlet end comprises a liquid inlet formed in one end of the passage. A liquid outlet channel is disposed between the liquid outlet and the other end of the passage and communicated with the passage. Cross-sections of different positions of the liquid outlet channel in a liquid outlet direction are of a rotationally symmetric shape corresponding to the shape of the liquid outlet. Through the liquid outlet in a rotationally symmetric shape and the corresponding liquid outlet channel, a discharged liquid column has a special shape under the acting force of liquid molecules in air.
