A handheld sprayer nozzle is provided that has dual levers connected to an internal rotary valve for easily and comfortably controlling and turning on and off the flow of water or other liquid or fluid emitted through the sprayer nozzle and out of its head from either side of the sprayer regardless of the orientation of the sprayer head relative to a user holding the sprayer nozzle. The handheld sprayer nozzle is connectable to an end of a pressurized hose. The sprayer nozzle's dual control levers are located on opposite sides of the sprayer nozzle so as to be generally located in positions opposite to one another and may be easily operated from either side of the sprayer nozzle by a user's thumb. The sprayer nozzle's head is also detachable so that sprayer heads of different lengths and spray patterns can be attached to the sprayer nozzle for different uses.

A spray gun includes a valve cartridge configured to be axially installed and removed as a single piece. The valve cartridge includes the wear components of the spray gun. A trigger of the spray gun is configured to actuate a slider of the valve cartridge to control spraying by the spray gun. The trigger includes arms that are mounted to the spray gun by a pivot mechanism. The pivot mechanism can be disengaged from the arms to allow the trigger to slide between a spray position, where the trigger prevents forward axial movement of the valve cartridge, and a repair position, where the valve cartridge can move axially forward. The trigger also includes upper and lower portions that are movable relative to each other, such that the length of the trigger can be adjusted.

A method for quickly replacing an air outlet pipe of an air blow gun includes providing a gun body, a C-shaped clamping ring, a rotation knob and a nozzle head, and rotating the rotation knob to rotate the clamping ring, moving the oblique guide faces of each of the clamping jaws of the clamping ring to touch the resting portions of each of the arcuate slots of the mounting head of the gun body, pressing outward each of the clamping jaws of the clamping ring, releasing the clamping jaws of the clamping ring from the locking groove of the nozzle head, detaching the nozzle head from the clamping ring, and detaching the nozzle head from the mounting head of the gun body. Thus, the nozzle head is detached from the gun body quickly.

An example portable fluid spraying system includes a handheld fluid sprayer. The handheld fluid sprayer includes a fluid reservoir configured to store a fluid, a pump configured to pump the fluid from the fluid reservoir to an outlet of the handheld fluid sprayer and a handle. The handheld fluid sprayer includes a first trigger proximate the handle, configured to control fluid flow to the outlet. The portable fluid spraying system includes a fluid hose having a coupling mechanism configured to removably couple to the handheld fluid sprayer proximate the outlet and a fluid spray gun. The fluid spray gun includes a gun inlet configured to couple to the fluid hose and receive the fluid from the handheld fluid sprayer, a gun outlet configured to expel the fluid in a spray pattern and a second trigger configured to control fluid flow to the gun outlet.

An electrically powered, compact, ready to use sprayer that includes a main housing. When the sprayer is used in conjunction with an electric motor, self-feeding undulating tentacles, a spinning element, a spherical boot, spherical boot outlet, feed hose, and an extended wand outlet it is able to pump low and high viscosity fluid, create a liquid spray, and dispense fluid in the forward direction with very few moving parts and minimum energy.

A cosmetic container assembly capable of simultaneously discharging multiple kinds of contents through a single pumping action is disclosed. The cosmetic container assembly includes a plurality of cosmetic containers, each of which includes a container and a pump dispenser, a press plate, which includes connection ports connected to hollow piston rods, a discharge port, a discharge channel connecting the connection ports with the discharge port, and a support shaft, a container housing including a base, a housing cap including a shaft hole and a button-supporting shaft, and a lever push button, which is coupled to the button-supporting shaft and includes a press portion configured so as to press the support shaft to move the press plate downwards to thus simultaneously press the pump dispensers when the lever push button is pressed.

A shower device has a fixing portion, an outlet portion and a switch portion. The fixing portion is disposed with an inlet waterway and at least two diversion waterways connected to the inlet waterway, the outlet portion is rotatable with respect to the fixing portion such to change the outlet direction, the outlet portion is disposed with outlet chambers corresponding to the diversion waterways one-to-one. The switch portion is disposed at the fixing portion and is coupled to the inlet waterway and the diversion waterways; before water flows to the outlet portion, the diversion waterways are switched to connect to the inlet waterway by movement of the switch portion relative to the fixing portion.

A battery-operated dispenser includes a shell with a moveable slider for extending a barrel of the dispenser to allow targeted application of a fluid or product from a container to which the dispenser is attached.

An oscillating range adjusting module with modular design for being mounted into a sprinkler is revealed. The oscillating range adjusting module which includes a first adjusting unit and a second adjusting unit is located between a water-in control module and an oscillation driving module. During assembly, the first adjusting unit is fitted on an inlet tube of a water-in control module. After an O-ring being connected to the first adjusting unit, the second adjusting unit is mounted on the inlet tube and connected to the first adjusting unit by at least one fastener of the second adjusting unit engaged with at least one connection surface of the first adjusting unit. Lastly a water inlet of the oscillation driving module is connected to the second adjusting unit. Thereby, a modular assembly of the oscillating range adjusting module between the oscillation driving module and the water-in control module is achieved.

A spray gun includes a gun body and valves configured to control flow of material and air through the gun body. A trigger is mounted to the gun body and is disposed relative to the valves such that the trigger actuates the valves in sequence to begin air flow and material flow. A sensor senses when the trigger is in an actuated state and the sensor causes a pump to begin pumping material to the spray gun. Release of the trigger causes the trigger to leave the actuated state. A detent mechanism holes the trigger in a detent state intermediate the actuated state and a resting state. The sensor does not sense the trigger with the trigger in the detent state. The trigger maintains the valves open with the trigger in the detent state.
