A hair dryer is provided that may include a main body, a handle, a flow path, and a fan. The handle may include a handle case and a handle frame. The handle frame may include a flow stabilizer located upstream of the fan. A fluid flowing in through an inlet may pass through the flow stabilizer to flow to the fan. A sound absorbing space to reduce noise may be formed between an inner circumferential surface of the handle case and the flow stabilizer.

A computer system receives user-specified settings for a custom formulation of a personal care product, obtains manufacturing parameters for the custom formulation based at least on part on the user-specified settings for the custom formulation; and transmits the manufacturing parameters to a manufacturing computer system. The manufacturing parameters are configured to initiate or guide a manufacturing process to produce the custom formulation of the personal care product. The computer system also receives user-specified settings for a personal care device having at least one computer-controlled component, obtains operational parameters for the personal care device based at least in part on the user-specified settings for the personal care device; and transmits the operational parameters to a remote computing device in communication with the personal care device. The operational parameters are configured to modify at least one operational characteristic of the at least one computer-controlled component of the personal care device.

Apparatuses and methods for drying objects are provided. The apparatus can comprise a housing configured to provide an airflow channel having an airflow inlet and an airflow outlet, an airflow generating element configured to generate an airflow through the airflow channel, and one or more radiation energy sources configured to generate infrared radiation and direct the infrared radiation toward an exterior of the housing. A device controller can control the operation of the airflow generating element and the one or more radiation energy sources, and a power element controller in connection with the device controller can control the operation of the power element that can provide power at least to the radiation energy source and the airflow generating element.

A method of controlling a brushless permanent-magnet motor having a phase winding and a rotor includes monitoring a value indicative of back EMF induced in the phase winding during oscillation of the rotor about a parking position, and using amplitude peaks of the value indicative of back EMF to calculate a time window in which to apply a drive voltage to the phase winding. The method includes setting a timer corresponding to the time window at a subsequent determined amplitude peak and applying a drive voltage to the phase winding during the time window.

The present disclosure relates to a hairdryer control method, a device and a storage medium. The hairdryer control method includes following steps: receiving a hairdryer turn-off signal for stopping the hairdryer; detecting whether or not there is a power down task, and executing the power down task when the power down task is detected. As a result, impact on the driving process of the hairdryer caused by some tasks being executed when the hairdryer is turned on can be avoided.
