A switchable water-saving valve including a water inlet substrate formed as an annular body which has a housing and a water inlet portion. The water inlet portion is fixedly arranged within the housing and has a water inlet and a water outlet extending therethrough. A flow channel substrate is fixedly arranged within the housing below the water inlet portion. Guide holes are formed circumferentially at intervals on the flow channel substrate and extend therethrough and are in fluid communication with the water outlet. A switch holder is rotatably positioned below the flow channel substrate. First and second pluralities of water flow holes are arranged circumferentially in the top surface of the switch holder and penetrate the top surface. Water outlet holes are formed on the bottom surface of an aerator holder and are in fluid communication with the first water flow holes. When the switch holder rotates to a first position where the first water flow holes are aligned with the guide holes, water flowing into the guide holes flows out of the water outlet holes through the first water flow holes.

A side sprayer includes an inactive configuration, a normal active configuration, and a locked active configuration. The side sprayer includes three buttons to allow the user to transition between configurations of the side sprayer.

The present invention provides a shower head system for the preservation of a water supply of a shower. The user is allowed the option to configure the water supply in a secondary outlet flow and a primary outlet flow. The secondary outlet flow, in some embodiments, is a droplet or rain-style flow. Without impeding the traditional or existing shower head the current invention allows the user to conserve water and customize different bathing experiences while doing so.

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.

A system and method of fluid delivery for providing a surface fluid pattern, the system comprising: a fluid delivery head for fluid flow therethrough, the fluid delivery head comprising: a fluid delivery surface having surface openings defined therein and arranged across the fluid delivery surface as a two-dimensional display; wherein at least some of the surface openings are grouped as a surface opening unit having at least one aspiration opening through which fluid can be provided to the fluid delivery surface and at least one injection opening through which fluid can be moved away from the fluid delivery surface, the surface opening unit comprising at least three surface openings positioned as a two-dimensional display and outwardly of at least one other surface opening.

The invention relates to a modular system for weed control for a rail vehicle. The modular system has a control unit for producing control signals for controlling valves and miners in a separate herbicide and mixing module and for producing a second set of control signals for controlling valves of a nozzle rod. The herbicide and mixing module has a container for holding different herbicides and electrical connection elements for connections to the control unit. Furthermore, a nozzle rod is present, which is tit ted with a nozzle set, in order to spray herbicides of the herbicide and mixing module. In addition, a camera module is present, which produces a weed signal in response to the detection of a weed, in order to control the spraying of the herbicides. The camera module is at such a distance from the nozzle rod that, despite high speed, there is sufficient time to provide the herbicide at the nozzles.
