A method for cleaning at least one workpiece and a cleaning device are described. The method includes: cleaning at least one workpiece held by a workpiece carrier in a treatment container, by at least one nozzle which discharges a cleaning jet directed onto the workpiece. The cleaning includes: specifying a rotational speed of the workpiece carrier and a circulation speed of the at least one nozzle on a circulation track about the workpiece carrier; rotating the workpiece carrier at the specified rotational speed; moving the at least one nozzle at the specified circulation speed about the workpiece carrier; and pivoting the at least one nozzle about a pivoting axis extending parallel to an axis of rotation of the workpiece carrier such that a specified point on a surface of the workpiece is impacted repeatedly by the cleaning jet at a respectively different angle, within a specified timeframe.

Provided are a system and process for remanufacturing a waste cylinder assembly of an aircraft piston engine. The spraying apparatus includes a first power mechanism, a spray gun assembly and a second power mechanism. The first power mechanism drives the cylinder assembly to move in a horizontal direction and a vertical direction. The second power mechanism drives the spray gun assembly to rotate around a center of the blind hole and ensures that prepared coatings can be evenly distributed along an inner wall of the blind hole. A nozzle end of the spray gun extends into the blind hole, and the spray gun is adjustable relative to the center of the blind hole. A spraying distance is not fixed so as to change the spraying distance. Powder can be fully melted.

A cleaning tool attachment reduces the amount of foreign matter or cleaning liquid remaining on a workpiece. The cleaning tool attachment includes a housing, a first shaft integrally connectable to a main spindle, a second shaft having an axial direction different from an axial direction of the first shaft, a plurality of tool mounting shafts having an axial direction parallel to the axial direction of the second shaft, a rotation axis conversion gear mechanism arranged in the housing, and a synchronous rotation mechanism arranged in the housing. The synchronous rotation mechanism transmits a driving force of the second shaft to the plurality of tool mounting shafts, and rotates the plurality of tool mounting shafts at the same rotational speed and with synchronous phase angles.

The present invention is applicable to the field of cosmetic instruments. The present invention discloses a nozzle rotating mechanism and a facial steaming apparatus, wherein the nozzle rotating mechanism comprises a nozzle and a driving mechanism for rotating the nozzle, the nozzle being located outside an axis of a nozzle shaft, the axis of the nozzle being parallel to or forming an angle with the nozzle shaft. The nozzle rotating mechanism is driven to rotate by a driving mechanism when it is in use. Since the axis of the nozzle is parallel to or forming an angle with the nozzle shaft, i.e., the axis of the nozzle and the nozzle shaft are not on the same line, so the nozzle must form a larger radius of rotation relative to the axis of the nozzle shaft when the nozzle rotates on the nozzle shaft. Therefore, the nozzle can form a larger area, which can increase the area of steam injection, better suit requirements from different users, and improve the user experience. At the same time, the structure is simple, compact, stable and reliable. The nozzle rotating mechanism is widely used in steam cleaning devices for facial steaming apparatuses.

A brewing chamber cleaner including a spinning or stationary assembly for spraying cleaning solution into the brewing chamber. The spinning assembly may be attached to a disk configured to removably reside in the brewing chamber, or be part of a coffee maker. Liquid pumped into the brewing chamber cleaner may cause the spinning assembly to spin by the liquid flowing past gears or a propeller, or by off center jets on the spinning member. Alternatively, the coffee maker includes a rotating shaft to cause the spinning assembly to spin or may include stator winding creating a rotating magnetic field to cause the spinning assembly to spin. In another embodiment the brewing chamber cleaner includes a wide spray provided by a fixed nozzle. A base is optionally provided to capture the spray and direct a flow into a bottom extraction needle of the coffee maker to clean the extraction needle.

A system and method have been shown for the effective implementation of a height and rotational adjustment system for a plurality of spray guns for use in a line striper.

A pipe conditioning tool comprising a drive unit to move the tool along a pipe and a work head rotatable about an axis of the pipe to condition a surface of the pipe, the drive unit includes a frame extending to opposite sides of the pipe, the frame having legs extending radially beyond the work head to provide support for the tool upon removal from said pipe.

A method for cleaning the cooking space of a cooking appliance with a pan including adding a cleaning agent to the cooking space and if necessary, after this agent has been allowed to work for a certain period of time, a liquid jet is introduced under high pressure from the a spray head of a cleaning device through the at least one spray nozzle, which rotates around an axis perpendicular to the rotational axis of the spray head rotating around this axis. The liquid jet consists exclusively of water and which swirls and splashes the cleaning agent, and if necessary, after this splashed agent has been allowed to work for a further certain period of time, removes the residues mechanically from the bottom, the walls, and the inside surface of the lid, and wherein said residues are then carried away together with the washing solution out of the cooking space via the drain.

The invention relates to a treatment device for workpieces, having the following: a treatment chamber (1); a shaft (2) which extends through a wall of the treatment chamber (1) into the treatment chamber and which is mounted in a rotatable manner; an electric treatment unit (3) which is secured to the shaft (2); and a power supply arrangement (6) with a first supply line (61), an electric coupling (63, 64), a second supply line (62), and an actuating unit (7). The electric coupling (63, 64) has a first coupling element (63), which is secured to the shaft (2) outside of the treatment chamber (1), and a second coupling element (64). The first supply line (61) connects the electric treatment unit (3) to the first coupling element (63), and the second supply line (62) is connected to the second coupling element (64). The actuating unit (7) is designed to actuate the coupling (63, 64) in order to bring the second coupling element (64) into contact with the first coupling element (63) or release the second coupling element (64) from the first coupling element (63).
