Abstract: 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.

Abstract: A trigger dispensing head applicable to a bottle of a trigger dispensing device is provided. The trigger dispensing head has a cylinder chamber, a main vent passageway, a sleeve, a secondary vent passageway, an axially slidable piston, a suction duct, and a dispensing duct. The sleeve is rotatable by a user between an angular working position in which the main vent passageway is in fluid communication with the secondary vent passageway and an angular rest position, in which the main vent passageway is fluidically separated from the secondary vent passageway.

Abstract: A full-plastic trigger spray pump, comprising a pump body (1). The lower part of the pump body (1) is connected to a locking cover (8); a liquid spray channel (11) is provided in the pump body (1); a nozzle (2) is provided at an outlet of the liquid spray channel (11); a liquid outlet channel (12) and a liquid inlet channel (13) which are vertically isolated from each other are provided in the pump body (1); the liquid outlet channel (12) is communicated with the liquid spray channel (11); a liquid guide chamber (14) is provided on a side of the liquid outlet channel (12) and the liquid inlet channel (13); the upper part of the liquid guide chamber (14) is always in communication with the liquid outlet channel (12) by means of a normally open port (15); a pumping piston (3) is provided in the liquid guide chamber (14); a trigger (4) capable of driving the pumping piston (3) to do piston movement in a left-right direction in the liquid guide chamber (14) is hinged onto the pump body (1); an elastic arm (5) capable of pressing against the pump body (1) and driving the trigger (4) to return the pumping piston (3) back is provided on the trigger (4); a lateral one-way valve that can be opened during the return movement of the pumping piston (3) so as to enable the liquid guide chamber (14) to be communicated with the liquid inlet channel (13) is provided between the liquid guide chamber (14) and the liquid inlet channel (13). The full-plastic trigger spray pump has simple structure and high liquid inflow efficiency, and can make full use of the solution pumped into the liquid guide chamber via a pump.

Abstract: The present invention relates to a spray gun head and a sprayer using the same. The spray gun head includes a connecting cap, a gun body, and a blank cap, where the connecting cap has an internal thread; the gun body is located above the connecting cap; and the blank cap is arranged on the connecting cap, and a lower end of the gun body is rotatably arranged on the blank cap along a circumferential direction of the blank cap, such that even if the gun body rotates under a force, the gun body can only rotate along the circumferential direction of the blank cap, without driving the connecting cap to rotate relative to a liquid container, thus avoiding the outflow of a liquid in the liquid container due to the rotation of the gun body.

Abstract: An aerosol sprayer may be connected to an aerosol container to form an aerosol delivery system. The aerosol sprayer includes a base secured to the container, a cap secured to the base, a pivoting trigger and a nozzle which is slidably movable relative to the trigger between an extended operable position and a retracted, locked position. The nozzle and trigger have interfitting locking structures to prevent actuation of the trigger when the nozzle is in the retracted locked position.
