The present disclosure generally relates to oral care systems and devices. An oral care system includes a container defining an interior portion and a moveable funnel configured to slide in the interior portion of the container. The moveable funnel includes a funnel portion having a base connected to a tube, where a distal end of the tube includes a cutting edge angled relative to a central axis of the tube. The system further includes a toothbrush supported by the tube, the toothbrush having a handle extending out from the container.

A suction toothbrush includes a handle defining an opening, a toothbrush head including internal channels, a seal with a distal end received within the toothbrush head and a proximal end coupled to the handle through the opening thereof, and a connector extending through the annular body of the seal. The connector includes a main body having a distal end disposed within the internal conduit of the toothbrush head and a proximal end extending into the handle through the top opening thereof, and a vibration motor housing offset from the proximal end of the main body. A waste reservoir for a suction toothbrush includes a lid, a basin defining a sump for waste material, and a gas-permeable membrane disposed between the lid and the basin that defines central inlet opening. A 3-D printing method for suction toothbrush heads.

A suction assembly, toothbrush, and method are provided that suction fluids and debris resulting from brushing. The suction assembly includes a housing configured to couple to the toothbrush so that a portion extends around sides and a back of the toothbrush head and is spaced from the toothbrush head by a gap. The suction assembly further includes a vacuum pump, a collection reservoir, and one or more conduits that couple the vacuum pump, suction head portion, and collection reservoir to apply a suction around the toothbrush head through the gap and deposit suctioned material in the collection reservoir.

A substrate processing apparatus configured to dry a substrate by replacing a liquid film formed on a top surface of the substrate with a supercritical fluid includes a pressure vessel having therein a drying chamber in which the substrate is dried; a cover body configured to close an opening of the drying chamber; a lock key configured to restrict the cover body from moving from a closing position where the cover body closes the opening toward an opening position where the cover body opens the opening; and a cleaning device configured to clean the lock key.

A detailing tool includes a housing having a first end and a second end opposite the first end, the first end configured to receive a battery pack. The detailing tool further includes a motor supported in the housing, the motor providing a rotational output. The detailing tool further includes an attachment plate supported at the second end of the housing. The detailing tool further includes a detailing attachment including a detailing implement configured to engage a surface, the detailing attachment being removably couplable to the attachment plate and receiving the rotational output from the motor.
