A powder coating plant for coating a workpiece with coating powder includes a booth, which receives the workpiece delivered via a floor conveyor. In addition, the powder coating plant has an upper spray applicator arrangement for spraying coating powder downward, and a lower spray applicator arrangement for spraying coating powder upward. The upper and the lower spray applicator arrangement are thereby oriented toward the same workpiece. In addition, a manipulator is provided, to which the upper and the lower spray applicator arrangement is fastened. The manipulator is formed such that the spray applicator arrangements can be moved at least in the transport direction of the workpiece by the manipulator.

A cylindrical portion forms, at a first holding position, a first airflow path in which a communication portion open to a lower end of the body serves as a first introduction port for the outside air and in which a missing portion lacking a portion of a surrounding wall of the cylindrical portion serves as, by overlapping a slit open to an outer peripheral surface of the body, a first exit through which the outside air flowed in the body is discharged to above the ceiling, and forms, at a second holding position, a second airflow path in which a gap formed between an escutcheon and a heat collector projecting from the lower end of the body serves as a second introduction port for the outside air and in which the missing portion serves as a second exit through which the outside air is discharged to above the ceiling.

A sanitary washing device including: a nozzle discharging water toward a human body private part; a water guide part including a pipe line reaching from a water supply source to the nozzle, and guiding water supplied from the water supply source to the nozzle; a vacuum breaker provided on a path of the water guide part, and taking air into the pipe line when water does not flow in the water guide part; and an ultraviolet irradiation part provided between the vacuum breaker and the nozzle on the path of the water guide part, and including a flow channel flowing water and a light emitting part irradiating ultraviolet rays to the water flowing in the flow channel is provided.

This technology relates to system for clearing a sensor cover. The system may include a sprayer, a support, and a positioning device. The sprayer may be mounted to the support and direct a flow of fluid to the sensor cover. The positioning device may be configured to adjust the position of the sprayer on the support. The system may include a nozzle and the nozzle may be positioned to direct the flow of fluid to an area of the sensor cover. The system may include additional sprayers.

A spray washing component for a smart toilet cover and an assembly method thereof are provided. The spray washing component includes a base, a nozzle, and a first motor. A sliding track is disposed on the base. The nozzle has a rack cooperating with the first motor. The first motor drives the nozzle to slide along the base. The first motor is installed at an end away from a jet of the nozzle and drives the nozzle to be displaced through a transmission structure. The transmission structure includes a driving gear, a dual transmission gear, and a conveyor belt. The driving gear is in anti-rotation cooperation with an output shaft of the first motor. The dual transmission gear respectively meshes with the conveyor belt and the rack on the nozzle. The spray washing component and the assembly method solve the large space occupation and insufficient aesthetics of the existing toilet.

An irrigation sprinkler can be provided with a flow guard feature configured to send an indicator stream into the air when a nozzle is missing, while still conserving most of the water that would have been wasted without the flow guard feature. The flow guard feature can include a valve assembly having a first port and a second off-axis port. The second port can be smaller than the first port. The second port can be non-parallel to the first port. The first port can be open when the nozzle is present and be sealed when the nozzle is missing. The second, off-axis port can be open even when the nozzle is missing to provide the indicator stream.
