Embodiments are directed to a fluid-emission device. An example fluid-emission device includes a tubular body, a fluid-source coupler, and a tip member disposed opposite the tubular body from the fluid-source coupler. A fluid-transmission lumen in the tubular body fluidly couples the tip member to the fluid-source coupler. The tip member includes a plate having a plurality of fluid-emission lumens that fluidly couple the fluid-transmission lumen to an environment outside the tubular body. The tip member includes a spearhead disposed opposite the plate from the fluid-transmission lumen. The tip member has a spacer disposed between the plate and the spearhead to separate the spearhead from the fluid-emission lumens. The fluid-emission device can be used by inserting the tip member into material and delivering fluid to a target, such as delivering water or fertilizer to plant roots or the like.

A water gun or toy water gun for dispensing liquid is disclosed. The gun includes at least one liquid dispensing outlet and at least one chamber housing that defines at least one chamber for storing liquid to be dispensed through the liquid dispensing outlet. For replenishing with liquid in a fast and convenient manner, the chamber is designed to be substantially uniform in cross section. An opening through which the liquid may be received in the chamber is also substantially the same size as the cross-section of chamber. The gun includes a lid that is pivotally movable between a closed position in which at least a portion of the opening is concealed by the lid and an open position in which the at least a portion of the opening is revealed by the lid.

A water spraying system includes an engine, a pump driven by the engine, the pump including a pump inlet configured to be fluidly coupled to a water source and a pump outlet providing water at an increased water pressure, a sprayer fluidly coupled to the pump outlet, the sprayer including a flow restriction valve and a trigger for manipulating the flow restriction valve so that movement of the trigger selectively opens and closes the flow restriction valve, a flow sensor configured to sense a flow of water into the pump, and a controller coupled to the flow sensor. The controller is configured to turn off the engine following a set time period of sensed flow below a threshold flow.

A rigid wand receives water under pressure from a pump. A canister of larger diameter than the wand receives the water from the wand with impact on flow disruptive material promoting aeration by turbulence. A large number of peripheral outlet ports allow water to tumble out of the canister through the ports.

The present invention refers to an interchangeable device comprising: a high-pressure pump unit (16002), a water intake (16003), and a lance (16005), characterized by a coupling system comprising: a shaped shaft (16001)-shaped hub (16007) coupling, an anti-rotation positioning element (16008), and a locking clamp (16009), wherein the coupling system allows a power generator of varying type (16006) to be coupled, rendering the device a high-pressure washer and/or a high-pressure sprayer.

The Rain Rocket is an inexpensive, compact, mobile irrigation device which can be attached to fences, gates, tree limbs, playsets, etc. in order to water lawn and garden areas. Incorporates irrigation head with modified attached spring-loaded C-clamp and treaded female garden hose connector. This unique design allows the apparatus to be attached to objects which elevates sprinkler high off the ground to irrigate more area, quicker and easier than traditional water sprinklers without ever having to bend over. Device can utilize many different nozzle configurations such as pop-up rotating, pop-up static or impact sprinkler heads. Perfect solution for watering difficult parkway, verge and set-back areas by attaching to fence or gate without ever having to leaving your own backyard.

A pumping device for liquids is described which comprises a tank for liquids, from which a feeding pipe of a pump with a solar panel draws. The tank consists of a supporting frame with tubular uprights and upper and lower horizontal connection lengths, which supports and surrounds a flexible bag for containing liquids and has an upper connection crossbar of the upper horizontal lengths of the supporting frame, on which the pump with solar panel is mounted. The bag has a lower filling hole or mouth, in which the feeding pipe can be inserted and an overflow hole made in the upper of part of its side wall in position lower than said mouth.

The present invention is directed to a device and methods for efficient application of liquid treatment substances to oil palm fruit.
