A remote trigger head for dispensing a liquid includes a rewindable tube (2) having a predefined length and a winder unit (70) for the automatic spring rewinding of the tube (2).

Exemplary embodiments of manual dispensers and actuating mechanisms are disclosed herein. An exemplary dispenser includes a housing, a receptacle for receiving a container of fluid and an actuating mechanism for causing fluid to be dispensed from the container. The actuation mechanism has a first pivot arm having a pivot point on a first end and a cam on a second end and a second pivot arm having a pivot point a first end and a curved contact surface on a second end. The actuating mechanism includes a pushbar. One of the first and second pivot members is connected to the pushbar. When the pushbar is pushed inward, the cam is configured to travel along the curved contact surface. Movement of the cam along the curved contact surface moves the engagement mechanism upward and downward in a substantially linear motion when the engagement mechanism is connected to a pump to cause the pump to prime with fluid and dispense the fluid.

A paint sprayer includes a housing and a syringe assembly coupled to the housing with a reservoir and a plunger positioned within the reservoir. The reservoir is configured to store fluid. The paint sprayer also includes a spray assembly in fluid communication with the syringe assembly. The spray assembly includes a spray nozzle and a spray tip. The spray tip is configured to expel fluid. The paint sprayer further includes a motor pump assembly disposed in the housing and an actuator operable to energize the motor pump assembly to draw fluid from the reservoir and expel it from the spray tip.

A material sprayer includes a hopper module and a power module. The power module is mountable and dismountable from the hopper module. The hopper module includes a hopper frame and a hopper supported by the hopper frame. The power module includes a drive and a pump connected to and configured to be powered by the drive. The pump interfaces with the hopper with the power module mounted on the hopper frame such that the pump can draw material from the hopper.

A spray gun includes a gun body, a motor and a water pump disposed in the gun body, and a power supply device; the motor is electrically connected to the power supply device; the water pump has its inlet in communication with the liquid inlet of the gun body, and its outlet in communication with the liquid outlet of the gun body; a liquid inlet check valve is arranged on the liquid inlet passage between the liquid inlet and the water pump, and a trigger mechanism is arranged on the gun body for controlling the opening of the liquid inlet check valve and the water pump. A cleaning device having the spray gun is also disclosed. The spray gun and the cleaning device can solve the liquid leakage problem.

A dispensing assembly for dispensing fluid generally includes a container having a handle located toward an upper portion of the container, and a sprayer having arms extending away from the sprayer. The arms of the sprayer define a channel configured to receive at least part of the handle of the container within the channel to thereby couple the sprayer to the container. Such a dispensing assembly can be made by forming the container with a handle located toward an upper portion of the container, and forming the sprayer with the arms such that the arms can be used to couple the sprayer to the handle of the container, where the arms extend away from the sprayer and define the channel for receiving at least part of the handle of the container into the channel.

A filling apparatus (110, 210) for a hermetically sealed bottle (200) is created by means of a dual bottle adapter (210), at least indirectly connected to the bottle (200), for an input of liquid from a storage container (100) provided with a dual container adapter (110) and at least partially filled with liquid, wherein between a liquid exit port (111) of the dual container adapter (110) and a liquid entry port (211) of the dual bottle adapter (210) a sealed-off liquid communication connection is present, and between a gas entry port (112) of the dual container adapter (110) and a gas exit port (212) of the dual bottle adapter (210) a sealed-off gas communication connection is present.

The invention discloses an automatic command device for imitation traffic police, which includes a fuselage, a first support rod is fixedly installed on the upper side of the stop card base, a stop card is fixedly installed on the right side of the first support rod, and a screw thread rotates to drive a thread. The push plate moves to the right, the threaded push plate moves to the right to squeeze out the water in the water storage tank through the water spray valve, control the command of the stop sign through the rack and pinion, and control the passing sign through the linkage mechanism. Command, design the screw and other transmissions, after pumping the water under the ground into the water storage tank, while showing the stop sign, the push plate squeezes the water out of the water storage tank and sprays on the ground to remind pedestrians and Vehicles should not do illegal acts, which will not hurt pedestrians or provide a warning effect.

A working machine may be provided with: a case configured to store water therein; and a working machine body configured to discharge water supplied from the case, in which the working machine body is detachably mounted on an upper surface of the case.

A closure assembly includes a vented closure and a dispensing fitment. The closure includes an upper deck, a tubular hub extending downwardly from the upper deck, an annular outwardly threaded fitment neck extending upwardly from the upper deck, and a fitment seat surrounding the fitment neck. The fitment seat has a vent hole radially spaced from the hub. The dispensing fitment includes a fitment body, an arbor extending downwardly from the fitment body, an annular inwardly threaded sealing wall extending downwardly from the fitment body, and a dispensing neck extending upwardly from the fitment body. The arbor is movable between an open venting position and a closed position which blocks the vent hole.
