A battery cleaning device, including a main body, including a first section comprising a first tapered end to remove corrosion around a post of a vehicle battery in response to being move around the post, and a second section movably connected to at least a portion of the first section, the second section comprising a second tapered end to remove the corrosion around the post of the vehicle battery in response to being moved around the post, and a spring disposed between the first section and the second section to bias the first tapered end toward the second tapered end.

The present disclosure relates to the field of smart home technologies, and proposes a base station and a cleaning robot system. The base station is configured to clean a cleaning system of a cleaning robot, and includes a base station body and a cleaning component. The base station body includes a cleaning groove, and the cleaning component is movably disposed on the base station body. The cleaning component includes a liquid outlet device, and cleaning liquid discharged by the liquid outlet device is configured to clean the cleaning system and enter the cleaning groove. After the cleaning component is positioned opposite to the cleaning system, the cleaning component moves, and the liquid outlet device moves along with the cleaning component. Then, the cleaning component can remove debris from the cleaning system. That is, the cleaning robot can realize automatic cleaning on the cleaning component.

A method for cleaning a ceramic matrix from a compaction roller includes steps of: (1) applying a cleaning fluid to the compaction roller; (2) scrubbing the compaction roller to remove ceramic particles of the ceramic matrix from a compaction-roller surface of the compaction roller, and (3) drying the compaction roller to remove the cleaning fluid from the compaction-roller surface.

A cleaning tool for an aerosol provision device, the cleaning tool including a cleaning head having a loop support and a plurality of bristles extending from the loop support.

A cleaning unit for cleaning a housing of a medical imaging apparatus surrounding a patient receiving area, including at least one cleaning element, wherein the at least one cleaning element has an annular carrier structure, and a diameter of the cleaning element comprises at least one value of a diameter of the housing surrounding the patient receiving area.

An apparatus and method for picking up spiked objects from surfaces is presented. In embodiments, a device includes a frame configured to receive a propulsion force to move the device along a surface. The frame includes a roller mounting assembly, and a roller assembly is removably attached to the roller mounting assembly. The roller assembly is configured to rotate about a longitudinal axis. The roller assembly is configured to cause spiked objects disposed along the surface to attach to the roller assembly as the roller assembly rolls over the spiked objects. A scraper is configured to detach the spiked objects from the roller assembly as the spiked objects attached to the roller assembly contact the scraper due to the roller assembly rotating, and a collection tray is configured to capture the spiked objects detached from the roller assembly by the scraper.

A real-time monitoring device for a polar nearshore marine environment is provided, including a cabin body, a main control cabin and a scraping structure, an outer wall of the cabin body is provided with collecting holes, an electric motor is arranged in the main control cabin, the electric motor provides power through a first rotating rod penetrating a side wall of the main control cabin. The scraping structure includes a power structure, a scraper and a collecting bucket, the scraper is arranged outside the cabin body and is fixedly provided with the collecting bucket. The power structure is connected to the first rotating rod and drives the scraper and the collecting bucket to rotate relative to the cabin body, the collecting bucket collects the floating objects on the outer wall and around the cabin body, and the floating objects enter the cabin body through the collecting holes.

Embodiments of the present disclosure are directed to additive manufacturing apparatuses, cleaning stations incorporated therein, and methods of cleaning using the cleaning stations.

A cleaning device for removing impurities from a bar-shaped structure includes a drive unit, and two roughing discs capable of being driven to rotate about a common axis of rotation. At least one roughing disc of the two roughing discs is capable of being driven by the drive unit. The two roughing discs form, along the common axis of rotation, a receiving region for the bar-shaped structure. Each roughing disc has, on a side facing the receiving region, a plurality of roughing projections. The two roughing discs are formed along the axis of rotation in a movably sprung manner in order to cause, in a state in which the two roughing discs are arranged on the bar-shaped structure, the roughing discs to be pushed onto both sides of the bar-shaped structure.

An alien substance removing apparatus according to one embodiment of the present invention may comprise: a hood unit provided adjacent to an electrical steel sheet and for collecting an alien substance generated in the electrical steel sheet by laser irradiation; and a scraping unit coupled to the hood unit and scraping and removing the alien substance attached to one surface of the hood unit facing the electrical steel sheet.
