An electric motor assembly for, for example, a hair dryer, includes an impeller, an outer housing in which the impeller is accommodated, an inner housing concentrically disposed in the outer housing, a stator having one side thereof accommodated in the inner housing, a rotor provided with a rotating shaft having one end coupled to the impeller and rotatably accommodated in the stator, a first bearing disposed at one side of the rotor, a second bearing disposed at another side of the rotor, and a bracket coupled to the stator and the outer housing so as to support the second bearing. Accordingly, initial alignment of the stator and the rotor may be securely maintained.

Disclosed is a hair dryer. The hair dryer includes a main body including a gas outlet portion disposed thereon, a handle extending from the main body and including a gas inlet portion disposed on a circumferential surface of the handle in communication with the gas outlet portion, a fan disposed inside the main body or the handle to flow gas, and a filter inserted into the handle through an insertion hole defined in a bottom face of the handle to filter gas introduced through the gas inlet portion.

A hair dryer apparatus includes a housing with a surrounding sidewall having an inner surface defining an interior and an opposing outer surface, further the sidewall having an inlet and an opposing outlet. In addition, the hair dryer apparatus includes a motor driven blower disposed within the interior, the blower drives airflow from the inlet to the outlet. Additionally, the hair dryer apparatus includes a handle extending from the sidewall and a suction shroud that includes a solid base with an outer surrounding sidewall extending from the base, wherein the outer surrounding sidewall has an outer termination portion that is scarfed such that the outer termination portion extends from the base to offset lengths toward the sidewall outlet thus ultimately the blower suction being adjacent to the sidewall outlet for noise attenuation and reducing user hair entanglement in the blower suction.

The invention discloses an air amplification type hair dryer. The air amplification type hair dryer comprises a handle, an outer cylinder, an inner cylinder, a fan and a control circuit; the fan is installed in an air duct of the handle, an annular cavity connected with a ventilation duct is formed between the outer cylinder and the inner cylinder, an annular nozzle is formed at the front end of the annular cavity, the control circuit is contained in the tail section of the annular cavity, and a transverse tunnel-shaped hole is formed in the tail section of the handle to serve as an air inlet, so that a direct transmission channel of fan noise is blocked, and the noise can be reduced to a certain extent; the fan is sleeved with a silencing barrel, the air inlet section of the silencing barrel is arranged to be in a step shape to be shrunk, and the step can prevent part of noise from being transmitted outwards from the source of the fan; inclined spray holes are formed in the inner cylinder so that the flow speed of airflow sucked into the inner cylinder can be further increased, and the air volume is increased; and the outlet section of the inner cylinder is horn-mouth-shaped, so that on one hand, an expansion channel can be provided for airflow entering from the inclined spray holes, and on the other hand, the angle of the wind beam can be enlarged, and the blowing range of the wind beam is enlarged.

A fan includes an air cylinder and an air outlet hood. An interior of the air cylinder is hollow to form a hollow cavity. The air cylinder has an air inlet and an air outlet. The air outlet hood is detachably disposed on the air outlet. The air outlet hood is provided with an annular air outlet for air outlet. An outer ring and/or an inner ring of the annular air outlet is formed with an annular guide rib extending toward the air inlet. The annular guide rib is configured to make an airflow cross section adjacent to the annular air outlet gradually decrease, so as to make an airflow in the air outlet hood cohesive, thereby increasing an air outlet speed of the annular air outlet. A hair dryer having the fan is also disclosed.

A hair care appliance is provided. The hair care appliance includes a handle and a body coupled to the handle via a rotational hinge joint. The body can be movable via the rotational hinge joint between a straight configuration in which the body is aligned with a longitudinal axis of the handle and a bent configuration in which the body extends along an axis transverse to the longitudinal axis of the handle. A fluid flow path extends between an inlet in the handle and an outlet in the body. The hair care appliance can be operated with minimal loss of fluid flow in either the straight configuration and the bent configuration. The hair care appliance includes a fan assembly in the handle and a heater assembly in the body that are positioned to create a balanced center of mass of the hair care appliance when operated by a user.
