Implementations of a hair cap are provided. In some implementations, a hair cap may be used to protect the hair of a wearer while they sleep and/or shower. In some implementations, a hair cap comprises a head portion, a pocket portion, and an opening. In some implementations, there may be an elastic band located about the periphery of the opening. In this way, the material about the opening of the head portion may be pulled against a wearer's scalp to potentially prevent water or other liquids from entering the interior of the hair cap. In some implementations, a fastener may be provided on the head portion and another fastener on the pocket portion of a hair cap. In this way the distal end of the pocket portion may be attached to the head portion thereby holding a wearer's hair off of their shoulders and back. In some implementations, silk may be used to manufacture the hair cap. In this way, the wearer's hair is protected from breakage.

A hair towel having a towel, and a tightening assembly with a cord assembly and a fastener. The cord assembly has an external and internal cord section, first and second ends, and a knot. The fastener has a body, an actuator, and a hole. The towel has an elongated channel to receive the cord assembly. The elongated channel has lateral ends, and defines a hole to receive the cord assembly. The elongated channel has at least one edge with stitching, whereby the stitching secures the elongated channel to the towel. The towel has exterior and interior faces, lateral edges, and first and second edges. The elongated channel is closer to the first edge than to the second edge, whereby the elongated channel is a first predetermined distance from the first edge without reaching the second edge. Furthermore, the elongated channel is approximately parallel to the first edge.

Presented is an improved and multifunctional headband. The headband includes an annular band portion to be worn about the head of a user for restraining and controlling user's wet hair strands, and extensions having a predefined shape and length and attached to the annular band portion extending away therefrom. The extensions are made of a fabric having absorption capability so that when inserted penetrating within the wet hair strands of the user, the extensions absorb water or water moisture from the wet hair strands of the user to dry them up. Further, the headband can be used to wring the hair to efficiently dry the user's wet hair without damaging user's hair. Furthermore, the headband can be worn as an accessory for decorative or ornamental purpose.

Disclosed herein is a motor including a bearing in which a rolling member is disposed between an inner ring and an outer ring, a spring connected to the outer ring, and a pusher connected to the spring to be retracted to a first position spaced apart from the inner ring by the spring, and to be advanced to a second position at which friction with the inner ring is caused by a pressure of air acting on a pressure surface when the pressure surface on which the pressure of air flowing by the impeller acts is formed, wherein the inner ring is spaced apart from the rotating shaft by a gap formed between the inner ring and the rotating shaft when the pusher is at the second position.

An air-moving appliance includes a body defining a cavity, an inlet for airflow to enter the cavity, and an outlet for the airflow to exit the cavity. The air-moving appliance also includes an attachment configured to connect to the body in flow communication with at least one of the inlet and the outlet. The air-moving appliance further includes a grip feature configured to extend between and contact the attachment and the body when the attachment is connected to the body. The grip feature is configured to provide an interference fit between the attachment and the body and resist movement of the attachment relative to the body when the attachment is connected to the body.

An air pollution prevention system is disclosed and includes at least one detection and processing device and at least one cleaning device. The detection and processing device includes a nano actuator, a nano photodetector, a carbon nanotube and a microprocessor, which are integrated as a single chip device through semiconductor manufacturing processes. The detection and processing device configured to detect a particulate matter and gas contained in an air pollution source and output a control command. The cleaning device includes a nano blower, a nano filter and a controller. The cleaning device receives the control command outputted from the detection and processing device through the controller to control the nano blower for guiding the air pollution source to flow through the nano filter for filtration.

A hair wrap article comprises a plurality of swaths of cloth dimensionally cut and stitched together to form the article comprising a volume, wherein an article first end comprises a first volume opening greater than a second volume opening at an article second end. The article comprises a securing tab at an exterior portion of the article first end or a plurality of through slits, either one to receive and secure the article second end. The article may comprise the following: the securing tab comprising an isosceles trapezoid geometric configuration; a secondary securing tab proximate the securing tab to alternately operate to receive and secure the article second end; a semi-rigid ribbing stitched into the stitched together portion of the article; and a portion of the second volume opening may be stitched together to close the second volume opening to create an article second end internal volume.
