Abstract: Provided is a hair dryer assembly. An example hair dryer assembly includes a housing and a handle. The housing has a side, an air outlet, and a rear opening. The handle is attached to the side of the housing. The hair dryer assembly further includes a heating wire disposed in the housing and an electric ventilator disposed in the handle. The hair dryer assembly further includes a magnetic ring recessed inside the air outlet of the housing and a diffuser removably attached, via the magnetic ring, to the air outlet of housing.

Abstract: The present disclosure provides a hair dryer including: a housing, having an air duct, an air inlet and an air outlet both communicated with the air duct; a fixing sleeve, arranged in the air duct of the housing, an inner wall surface of the fixing sleeve being provided with an elastic contact layer; and a fan, embedded in the fixing sleeve and abutted against the elastic contact layer. The present disclosure aims to reduce the fan vibration during the operation of the hair dryer, so as to reduce the noise generated by the hair dryer, thereby mitigating the impact of the noise on users.

Abstract: The present disclosure provides a hair dryer, including: a housing provided with a main control board; a power line connected to the housing and extending out of the housing; and a conductive metal sheet fixed to an inner wall of the housing, and configured to electrically conduct the main control board with the power line.

Abstract: A UV photocatalytic air purifier/sterilizer in which the multiple limited-lifetime components (such as the UV light, UV light electronics, and catalytic portion) of a photocatalytic UV air purifier/sterilizer are packaged together to form a single, handheld, unitized package, designed for easy insertion and removal into an air purifier. The invention may be configured enable maximum air flow through the photocatalytic portions of the device, thus further improving air cleaning efficiency by allowing many volumes of room air to be recirculated through the device and cleaned/purified/sterilized over the course of a day. In a preferred embodiment, the device may package a series of stacked TiO2 coated parallel metal catalytic plates, a UV germicidal lamp with a fluorescent tube form factor, and a UV lamp ballast into a single disposable or recyclable unit. This disposable unit can be easily clipped into a motorized air purifier unit designed for rapid servicing.
