An exemplary dispenser includes a base having at least one rail, a cover, and a mounting portion for a refill unit having a container for fluid. The cover is slideable along at least one rail of the base between a closed position and an open position.

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.

An improved container suitable for use with a nesting sprayer handle is provided. The container includes a container handle opening with an improved top wall geometry. The top wall geometry resists deformation to reduce or eliminate accidental dislodgment of a sprayer handle when the sprayer handle is nested in the container handle opening.

A painting system that makes use of drones such as modified quadrotors. The drone includes a support arm that carries a paint nozzle configured for pan and tilt motion. A power supply line is connected from an external power supply to the drone to allow extended flight time. A paint supply line is also connected from an external paint supply to the drone to allow extended painting time and/or surface coverage with each flight. The drone has an onboard controller so painting is autonomous with no human input being required. The drone stores a 3D model of the target structure annotated with the drone trajectory plus commands to control the pan-tilt paint nozzle to perform the painting. At runtime, the controller uses a sensor to view the target structure and localizes itself. The drone then traverses the stored trajectory and implements the painting commands to paint the 3D structure's surfaces.

A sealing device for a system for applying a liquid coating product comprises an inner conduit suitable for sealably surrounding an actuating rod of the application system, a frame and a sealing gasket made from a synthetic material comprising an O-ring mounted around a lip of the gasket suitable for being pressed against the actuating rod, the frame and the gasket forming a single-piece assembly suitable for being mounted in a housing of the application system.

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 pressure washer structured to output a pressurized fluid including an engine having a throttle plate structured to move between a closed position and a wide-open position, a pump driven by the engine and having an inlet and an outlet that discharges fluid, a spray gun having a spray gun inlet fluidly coupled to the outlet of the pump and a nozzle structured to discharge the fluid and having selectable nozzle orifices, and an electronic governor system structured to control a speed of the engine. The electronic governor system includes a carburetor, a motor coupled to the throttle plate to move the throttle plate between the closed and wide-open position, and a controller coupled to the motor to control the motor to control the speed of the engine in response to a selection of at least one of the one or more selectable nozzle orifices.

A nozzle device applied to a high-pressure cleaning machine is provided, including: a nozzle, including a nozzle casing, where a water outlet channel is provided in the nozzle casing, and a front end of the nozzle casing is provided with at least one liquid discharge port connecting with the water outlet channel; and an exhaust valve, connected to the nozzle casing, and including: a valve seat, provided with a valve cavity; and a valve core, movably arranged in the valve cavity; where the valve seat is provided with an air inlet hole and an air outlet hole, the water outlet channel and a main exhaust passage are arranged in parallel in the nozzle casing, and the valve core is movable relative to the valve cavity to a closed position for blocking the main exhaust passage and an open position for opening the main exhaust passage. In the nozzle device applied to a high-pressure cleaning machine and a handheld high-pressure cleaning machine that are provided in this application, the exhaust valve is provided, and the exhaust valve implements an exhaust function at the open position, and implements a water outlet function at the closed position, thereby implementing self-suction and ensuring that a pressure anomaly is quickly eliminated within a short time during use, to meet a use requirement.

The present disclosure relates generally to liquid dispensing systems and more specifically to liquid dispensing systems having a reusable dispensing fixture and a reusable spray dispenser.
