A washing apparatus for viewing an obscured surface to be cleaned via a camera includes a base tube defining a base channel and an extension tube defining an extension channel. The extension tube is removably attachable to the base tube such that the base channel and the extension channel are in fluid communication with each other. A cleaning attachment is removably attachable to either one of the base tube and the extension tube and may be shaped to allow fluid to flow from the base channel or the extension channel and toward a surface to be cleaned. A camera is attached to the extension tube and is oriented to face the cleaning attachment when the cleaning attachment is attached to the extension tube.

A device (100) for cleaning and method of cleaning an endoscope distal end (128) is disclosed. The device (100) may include a sealed longitudinal chamber (110) that may contain a porous structure (132) with fluid, and a brush and a spring (121) loaded brush. A removable substantially airtight closure (146) may be removed to allow an endoscope distal end (128) to be placed into the longitudinal chamber (110) and contact the porous structure (132) and the brush prior to a full cleaning, thereby preventing contaminates from drying and hardening on the endoscope distal end (128) prior to a cleaning and sanitization process. The spring (121) loaded brush may be moved to clean portions of the endoscope distal end (128) including cavities such and tools including an elevator or lifter. A cap may be removed from a airtight connector (120) and a fluid source may be connected to the airtight connector (120) to assist in the endoscope (127) cleaning process.

Ergonomic handles and cartridge systems that support a hand-tool working end or a whole tool (such as a paintbrush) while being received comfortably in the user's hand when it is in its natural resting angle with respect to the wrist. The holder is configured to operationally engage with a cartridge of one more parts that supports or is configured to receive and support a tool.

A broom bracket for a push broom which serves to provide strength between the connection of the handle and the broom block while inhibiting the rotation of the handle relative to the block and any loosening of a threaded connection therebetween.

A toothbrush head includes a bristle tray, a base having an opening for receiving an electric toothbrush a drive shaft, a stem that connects the bristle tray to the base, and a coupling member, The coupling member does not require a spring to contact the drive shaft or stem. In some embodiments, the coupling member includes an interior sidewall that surrounds a chamber for receiving the drive shaft and a receptacle positioned to align with an opening of the stem, and a pin is positioned within the opening and the receptacle. In other embodiments, the coupling member includes a relatively narrower section positioned to align with the stem and a relatively wider section positioned to align with the base, and when the drive shaft is inserted into the coupling member, the drive shaft will extend from the relatively narrower section and into an interior cavity within the stem.

A pool cleaning assembly kit includes a utility connector, a handle base and one or more utility tool. The utility connector includes a connecting dock and two end connectors integrally provided at two ends of the connecting dock respectively. The handle base includes a handle frame detachably connected to the utility connector and configured to be detachably connected with a handle. The one or more utility tool is configured to be detachably connected to at least one of the end connectors so as to integrally assemble with the utility connector to form a cleaning tool.

A toothbrush holder is disclosed, the toothbrush holder may include: a handle, where the handle has a top provided with a fixing head, and the fixing head is provided with a plurality of second sliding rails; and a toothbrush bar, where the toothbrush bar is provided with a first sliding rail, and the toothbrush bar has a front end provided with a rotating head, the rotating head is provided with a third sliding rail, the first sliding rail is mutually communicated with the third sliding rail, and a side of the rotating head is rotationally connected with a side of the fixing head so as to enable the second sliding rail to be mutually communicated with the third sliding rail. In addition, a multi-face toothbrush having a plurality of toothbrush heads is disclosed, which achieves the effect of one toothbrush holder having a plurality of toothbrush heads.

Autonomous oral cleaner, comprising a head with a cleaning element, a container of a liquid cleaning fluid, and mechanism to carry the liquid fluid from the interior space of the container to the cleaning element in which a manual air pressure device participates, whose activation increases the pressure of the liquid fluid contained inside the container; The oral cleaner further includes a single whole set consisting of a first module that includes the head with the cleaning element, and a second module that includes the container the first and the second modules of the whole set have longitudinal and coaxial mobility relative to each other to move the fluid from the container to the cleaning element.

A brush for a sonic toothbrush with longitudinal axis vibration having an elongated base body has a frustoconical base portion with a drive adapter for rotation-fixed coupling to a sonic toothbrush drive with longitudinal axis vibration, and a head portion with a bristle support in which a plurality of bristles are anchored, and an elongated neck portion connecting the base portion and the head portion is disclosed. The base body forms a kink angle in that a geometric base portion longitudinal axis and a geometric head portion alignment axis include an angle in the range of 5 to 12. A geometric kink position in the base body has a distance from an end face of the base portion of at least 50% of a total length of the base body.
