This invention relates to a fluid nozzle such as a garden hose nozzle of the type having a trigger lock for the nozzle trigger handle. The garden hose nozzle will lock the trigger handle if the nozzle is accidentally dropped while in use in dispensing water to thereby prevent the accidentally squirting of water from the nozzle when the handle hits a surface. The nozzle trigger handle has a locking arm mounted through the trigger handle which is spring biased to raise the locking arm when the handle is released.

A water discharging device includes a body including a first water channel connected to a water supply source, and a second water channel connected to the first water channel and to an external entity; and an opening and closing portion including a first opening and closing member opening and closing a first opening and closing hole formed in the first water channel, and a second opening and closing member opening and closing a second opening and closing hole formed in the second water channel. The first opening and closing member moves along the first water channel to open and close the first opening and closing hole as the second opening and closing member moves in the second water channel to open and close the second opening and closing hole.

A nozzle gun includes a nozzle main body, an operating member attached to the nozzle main body to be movable toward and away from the nozzle main body, and a stopper attached to the nozzle main body to be pivotable between a locked position and a non-lock position and having a locking portion and receptacles, wherein when the operating member is moved toward the nozzle main body and the stopper is placed in the locked position, the locking portion engages with the operating member to prevent the operating member from moving away from the nozzle main body, when the stopper is in the non-lock position, the locking portion does not engage with the operating member, and when the operating member is moved toward the nozzle main body with the stopper in the non-lock position, the operating member presses the receptacles to cause the stopper to pivot into the locked position.

A fluid applicator configured to reduce user fatigue is presented. The applicator comprises an inlet and an outlet fluidically coupled by a fluid path. The applicator also comprises a trigger. The trigger is configured to, when actuated, move between a closed position and an open position. The open position comprises a fluid flowing from the inlet, to the outlet, along the fluid path. The applicator also comprises a trigger support configured to reduce a pressure required to maintain the trigger in an open position. The trigger support is configured to reduce the pressure required as the trigger actuates between the closed position and the open position.

A switchable shower head includes a waterway device and a waterway switch device that has at least two outlet functions. The waterway switch device has a water diversion plate that can rotate to switch the outlet function. The waterway switch device includes a ratchet wheel, which is coaxially connected to the water diversion plate; a transmission rack, which is disposed to the waterway device and is capable of moving away or closing to the ratchet wheel, the transmission rack is reset by two or more than two elastic elements; a transmission element, which is slidably assembled to the transmission rack and is capable of abutting against the ratchet of the ratchet wheel to move the ratchet wheel to rotate, an angle is formed between the sliding direction of the transmission element and the sliding direction of the transmission rack; and a driving mechanism.

A nozzle gun includes a nozzle main body, an operating member attached to the nozzle main body to be movable toward and away from the nozzle main body, and a stopper attached to the nozzle main body to be pivotable between a locked position and a non-lock position and having a locking portion and receptacles, wherein when the operating member is moved toward the nozzle main body and the stopper is placed in the locked position, the locking portion engages with the operating member to prevent the operating member from moving away from the nozzle main body, when the stopper is in the non-lock position, the locking portion does not engage with the operating member, and when the operating member is moved toward the nozzle main body with the stopper in the non-lock position, the operating member presses the receptacles to cause the stopper to pivot into the locked position.

A spray wand for use with a chemical or chemical formulation in solid form. The wand hose end has a wand hose end valve for control of water flow from a hose. A refill cartridge having a swirl chamber may be attached to the hollow tube. The refill cartridge has at least one nub, indent and/or external channel or groove on its external surface.

One embodiment includes a dispenser device and container for mixing a chemical concentrate and a diluent to produce a diluted mixture. The dispenser device may include a housing, a slide, and an eductor. The container holds the chemical concentrate. The dispenser device communicates with the chemical concentrate and with the diluent.

A packaged film for masking an aircraft component, wherein the packaged film is configured to form a tubular sleeve when unpackaged. The packaged film is formed by performing a longitudinal telescopic folding operation on a longitudinal portion of a film to provide a longitudinally parallelogram-shaped stacked film; and performing at least a first transverse folding operation on a first portion of the longitudinally parallelogram-shaped stacked film, the first transverse folding operation comprising an operation selected from accordion folding and roll folding to provide the packaged film. The packaged film is capable of being unfolded in a reverse order of the longitudinal telescopic folding operation and the first transverse folding operation to cover said aircraft component.
