The present invention relates to accessories. Specifically, the present invention relates to cleaning accessories such as jewelry that have small crevices, impressions, engravings, or other fine details that are difficult to reach and clean. Even more specifically, the present invention relates to polishing and drying the cleaned accessories by using an allotment of polishing compound and/or steam.

A processing liquid nozzle according to an aspect of the present invention comprises an ultrasonic application part (60), a first supply flow path (71), a discharge flow path (72), and a second supply flow path (73). The ultrasonic application part (60) has a vibrator (61) for generating ultrasonic waves, and a vibrating body (62) joined to the vibrator (61). The first supply flow path (71) supplies a first liquid (L1) to a position contacting the vibrating body (62) of the ultrasonic application part (60). The discharge flow path (72) supplies the first liquid (L1), to which ultrasonic waves have been applied by the ultrasonic application part (60), to a discharge port (74). The second supply flow path (73) is connected to the discharge flow path (72) on the downstream side from the ultrasonic application part (60), and supplies a second liquid (L2) to the discharge flow path (72).

An outdoor surface cleaning apparatus having a handle, a power head with a prime mover, an attachment head having a cleaning attachment, and a spray mechanism. The spray mechanism includes a first fluid input, a second fluid input, a cleaning fluid output, and a mixing assembly. The mixing assembly is in fluid communication with the first fluid input, the second fluid input, and the cleaning solution output.

The present application provides a machine cleaning device. The machine cleaning device includes: a guide rail arranged next to a carrying platform of the machine main body, a support slidably mounted on the guide rail, a cleaning component mounted on the support, a driving device connected to the support in a transmission way, and a controller connected to the driving device; and when the cleaning component cleans the top surface of the machine main body, the controller controls the driving device to drive the support to move along the guide rail, so as to drive the cleaning component to clean the top surface of the machine main body in a direction away from the carrying platform. So that unexpected particles are reduced to fall on the carrying platform and contaminate the carrying platform during the cleaning process.

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.

An automatic mold cleaning device includes an automatic cleaning system, a mold clamping system and a waste recovery system.

A pressure washer includes a pump for pressurizing a primary fluid flow, the pump including a pump inlet for receiving fluid from a common fluid source and a pump outlet for supplying a pressurized primary fluid and a jet pump including a primary fluid inlet fluidly coupled to the pump outlet, a secondary fluid inlet configured to receive fluid from the common fluid source, and a fluid outlet. In a high pressure operating mode, all of the pressurized primary fluid flows through the jet pump and exits through the fluid outlet of the jet pump. In a high flow operating mode, all the pressurized primary fluid flows through the jet pump and entrains a secondary fluid supplied through the secondary fluid inlet from the common fluid source so that the secondary fluid also flows through the jet pump, resulting in a combined fluid flow of the primary fluid and the secondary fluid that exits through the fluid outlet of the jet pump.

The present invention refers to a device for the discharge of a pressurised liquid comprising: a liquid intake section (2400), a liquid discharge lance (2300), a pump (2200), which can be connected to a motor (2100), the pump having an inlet connected to the intake section and an outlet connected to the discharge lance, where the discharge lance and the pump are connected by a connection (2800, 2801, 2802, 2803, 2804), with at most three rotational degrees of freedom and/or one translational degree of freedom.

A liquid dispersion device comprising an elongated dispersion body comprising a first end extending in a first direction and forming an elongated dispersion body comprising a first end positioned at an acute angle relative to a longitudinal axis of the elongated dispersion body, a second end positioned at an obtuse angle relative to the longitudinal axis of the elongated dispersion body, a plurality of nozzles extending outwardly from a forward surface of the dispersion body and a source connector on a rear surface of the dispersion body, the source connector in fluid communication with the plurality of nozzles. A first nozzle among the plurality of nozzles is positioned on the forward surface of the dispersion body at the first end of the dispersion body and a second nozzle is positioned on the forward surface of the dispersion body at the second end of the dispersion body.

An electric pressure washer includes an electric motor operably connected to a pump, one or more removable detergent tanks, a removable accessory bucket in which a spray gun, high pressure hose, and other accessories may be stored, and a foot pedal for facilitating operator control of one or more features of the electric pressure washer during use. The electric pressure washer may also include a folding handle for facilitating storage and transport.
