Spray apparatus and uses thereof are described herein. A vacuum spray nozzle apparatus may include a first tube in fluid communication with a fluid source, a rotor coupled to the tube, a conduit in fluid communication with the passages of the first tube, and a second tube coupled to the conduit, the second tube being in fluid communication with a vacuum source. The rotor is in fluid communication with the pressurized fluid source. The conduit is substantially arched or angled such that an outlet of the conduit is offset a radial distance in a radial direction from the rotor axis, and when pressurized fluid is ejected from the outlet, during use, rotates the conduit. The vacuum spray nozzle apparatus is configured to remove components from a material through the second tube when a pressure of the system is reduced using the vacuum source.

A remote-controlled gasoline cleaner including a main unit, sprayer, and remote control. The main unit includes a controller, start switch device, stop switch device, and gasoline engine start/stop apparatus. The remote control sends a start remote control signal or stop remote control signal to the main unit. The controller controls the start switch device in response to the start remote control signal received, and controls the stop switch device in response to the stop remote control signal received. The start switch device receives a start command of the controller to connect to a power supply circuit of a starter motor in the gasoline engine start/stop apparatus. The starter motor starts a gasoline engine. The stop switch device receives a stop command of the controller to connect to a short circuit of an ignition coil in the gasoline engine start/stop apparatus, thereby blowing out the gasoline engine.

An electric power washer contains a main body having a pump and an electric power source, a hose, a handle, and a control circuit. The hose contains a first end fluidly-connected to the pump and a second end fluidly-connected to the handle, which has a button operatively-connected to the control circuit, which is operatively-connected to the pump and the electric power source. The control circuit controls the pump output and contains a timer. The control circuit permits the pump to normally operate at up to 100% normal power. However, when the button is activated, the control circuit permits the pump to operate at a boost power mode of from about 103% normal power to about 300% normal power. The control circuit intermittently pulses the boost power mode and terminates the boost power mode after a predetermined period of time or when the button is no longer activated, whichever is shorter.

Provided is a spray head structure (1), comprising an airflow pipe (10), a rotary member (30), a load member (70), a tan component (100), a spoiler pipe (41) and a liquid flow pipe (50), wherein the rotary member (30) is rotatable sleeved on the airflow pipe (10), the load member (70) is mounted at the rotary member (30) to increase the load so as to improve the torsion of the rotary member, the fan component (100) is mounted at the rotary member (30). the spoiler pipe (41) is fixedly arranged on the rotary member (30) and is provided with a spoiler channel (41) in communication with the airflow pipe (10), and the spoiler channel (41) is provided with an outlet end (411), and an injection path forming an acute angle 0 with the axis of the airflow pipe (10), Gas at a high flow rate enables the spoiler pipe to drive the rotary member to rotate relative to the airflow pipe, such that the fan component is driven to rotate to form an airflow, so that the air flow can flow from the fan component to the outlet end to improve the atomization effect thereof, or can flow from the outlet end to the fan component to perform the suction of impurities.

A formulation delivery system configured for outdoor use. The formulation delivery system includes a cleaning composition comprising chlorine, wherein the composition is in a form of a solid chemistry, and an outdoor cleaning device that is a spray wand having the cleaning composition positioned within a dispensing cartridge housed within the outdoor cleaning device.

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.

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 invention relates to a system for outputting a mixture generated from at least one gas flow and at least one fluid flow onto a surface (50). The mixture (14) can be fed into a device (7) for outputting the mixture (14). The device (7) for outputting the mixture (14) comprises a gas-carrying line (2) in the interior (39) of which a fluid-carrying line (5) extends axially. The gas-carrying line (2) and the fluid-carrying line (5) are implemented as an outlet device (4) for outputting the mixture (14). The outlet device (4) is further implemented so as to be eccentrically rotatable about the longitudinal axis (12) of the gas-carrying line (2) and further comprises a body (59) for cleaning the surface (50).

An air nozzle comprises a body, the body having a first end for coupling to an air gun, and a second end having bristles, the body having a channel therethrough allowing air (or other fluids) to pass therethrough. In one example, a scraper may be coupled to the second end in place of bristles. A user may then easily clean a surface using the bristles, scraper, and air or water.
