An impeller assembly configured to produce low noise is provided. In one embodiment, an impeller assembly is provided having a hollow cylindrical hub body with a sleeve extending therethrough. The sleeve is configured to receive a driveshaft of a motor to couple the impeller assembly to the motor. The impeller assembly includes a plurality of impeller blades extending radially outward therefrom. Each blade of the plurality of impeller blades is unevenly distributed around a circumference of the hub body.

A nozzle structure with a plurality of bristle bunches includes a mouth-shaped casing and a plurality of bristle bunches. The mouth-shaped casing has a first end portion with an air inlet and a second end portion opposite to the first end portion. The second end portion has a plurality of outlet pores arranged in parallel and a plurality of bristle pores. Each of the outlet pores connects to the air inlet via a ventilated space inside the mouth-shaped casing, and the plurality of bristle bunches are implanted in the bristle pores of the mouth-shaped casing. In addition, the bristle bunches protrude further out from the outlet pores.

A makeup application apparatus is disclosed. The apparatus may include a handle including a handle top portion and a handle bottom portion. The handle top portion may include a plurality of vents. The apparatus may further include a brush head removably attached to the handle top portion. The brush head may include a brush head top portion and a brush head bottom portion. The brush head top portion may include plurality of bristles. The apparatus may further include a heating element disposed in a handle interior portion between the handle top portion and the handle bottom portion. The heating element may include a heater and one or more fans. The heating element may be configured to blow hot air towards the plurality of bristles via the plurality of vents.

Various exemplary attachments for hair care appliances and methods of using attachments for hair care appliances are provided. In general, a hair care attachment in an exemplary embodiment is in the form of a brush accessory that has a hollow body having first and second region, an attachment collar at a first end of the hollow body and having an inlet for receiving airflow, a plurality of bristles positioned along the first region of the hollow body, a plurality of outlet openings positioned along the first region of the hollow body adjacent the plurality of bristles, and a heater assembly positioned along the second region of the hollow body.

A mobile trailer-cleaning system is a system that facilitates the cleaning of the exterior surfaces of a trailer. The system may include at least one brush assembly, a roof carriage, an agitation mechanism, and a steering assembly. The at least one brush assembly enables the cleaning of all the trailer's exterior surfaces including the rear of the trailer and any non-flat surfaces. The roof carriage serves as a guide to maintain the at least one brush assembly adjacent to the trailer's walls as the at least one brush assembly moves along the trailer. The roof carriage also prevents the at least one brush assembly from tipping over. The agitation mechanism eases the cleaning of the trailer's exterior surfaces by agitating the at least one brush assembly in predetermined modes of operation. The steering assembly enables the user to manually operate the at least one brush assembly during the cleaning process.

A personal care implement with a fluid dispensing system includes a fluid applicator, a fluid dispensing assembly including main and overflow reservoirs, and a capillary member in fluid communication with the reservoirs and the applicator for dispensing personal care fluid stored in the reservoirs via capillary action. An air venting system in one arrangement allows ambient air to be drawn into the main reservoir through the overflow reservoir for alleviating vacuum formed in the main reservoir by the capillary action fluid dispensing process. The venting system may include an external vent to atmosphere from the overflow reservoir and an internal vent between the reservoirs. In the event air trapped within the main reservoir expands due to changes in altitude or temperature, fluid in the main reservoir is expelled into the overflow reservoir via the internal vent. In one implementation, the personal care implement may be an oral care implement.
