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.

A scent dispenser may comprise a vial retaining mechanism, a heating element, vial sensor, and a controller. The vial retaining mechanism includes a vial coupling that removeably retains a vial containing a scented solution. The includes a wick extending from a cavity of the vial through an opening of a neck of the vial. The heating element is shaped to receive and heat the wick of the vial. The vial sensor includes an array of sensor pads that are arranged in alignment with the vial retained by the vial coupling. The controller is electrically coupled to the heating element and electrically coupled to the array of sensor pads. The controller regulates a temperature level of the heating element, and receives signals from the array of sensor pads and processing the signals to determine a fluid level of the vial.

A thermal immersion circulator can comprise a heater including a hollow cylindrical main body having an inlet opening at a first end thereof and an outlet opening in a side wall thereof. The heater can include a flexible circuit board having a plurality of resistive bands controlled by controlling electronics such as TRIACs, which can be water-cooled. A thermal immersion circulator including such a heater can be used in scientific laboratories or sous vide food cooking.

A cosmetic application assembly for heating, dispensing, and applying a cosmetic includes a handle that is tubular and defines a reservoir. Each of a plurality of brushes is selectively couplable to a first end of the handle. An opening that is positioned in a second end of the handle is configured to insert a cosmetic. A heating and dispensing module is selectively couplable to the second end of the handle and is in fluidic communication with the reservoir. The heating and dispensing module is configured to draw the cosmetic from the reservoir, to warm the cosmetic, and to dispense the cosmetic through a hole that is positioned in the heating and dispensing module. The user is positioned to apply the cosmetic to a skin surface and to utilize the handle to manipulate a respective brush that is coupled to the handle to spread the cosmetic.

A snow shovel that has a shaft, a handle, and a scoop to allow the user to remove unwanted snow and ice from a surface. This shovel includes a heated bottom edge with a vibrating motor to melt and dislodge ice or snow from a surface. The shovel also includes a vibration-reducing mechanism to dampen the vibrations that a user might feel during the use of this shovel, along with sensors that detect when the heated edge and motor should be turned on or off.

The bug repellent system is configured for use in repelling insects. The bug repellent system is an electrically powered device. The bug repellent sublimates an essential oil contained within a cartridge. The cartridge is a solid phase of a solution comprising the essential oil dissolved in a paraffin solvent. The selected essential oil is an insect repellent known to repel mosquitos. The bug repellent system is worn by a client. The bug repellent system comprises a housing, the cartridge, and a sublimating device. The housing contains the cartridge and the sublimating device. The sublimating device warms the cartridge such that the essential oil sublimates into the atmosphere from the cartridge. The housing is worn by the client.

A water heater appliance, as provided herein, may include a casing, a tank, an inlet conduit, an electric heating system, and a controller. The tank may be disposed within the casing, the tank defining an inlet and an outlet. The inlet conduit may be mounted to the tank at the inlet of the tank. The electric heating system may be in thermal communication with the tank to heat water within the tank. The controller may be in operative communication with the electric heating system. The controller may be configured to initiate a responsive-heating cycle. The responsive heating cycle may include detecting expiration of a dormant event at the water heater appliance, initiating a randomized delay period in response to detecting expiration of the dormant event, and initiating activation of the water heater appliance following the delay period.

Aspects of the instant disclosure relate to electronic cigarettes; more particularly, to electronic cigarettes including a power supply portion. In various embodiments, the eCig power supply portion includes a sub-assembly housing substantially containing a battery, an airflow sensor, and controller circuitry. Aspects of the disclosure are further directed to an eCig power supply portion further including a hemicylindrical port and/or electrical contacts aligned along a longitudinal axis of the power supply portion.

The present invention provides disposable capsules and electronic inhalers designed to be used therewith, and to methods for consuming cannabis in a clean, simple and efficient way, which is also cost effective.

An aerosol generating device according to an embodiment includes a heater generating an aerosol by heating an aerosol generating substrate; a controller for controlling power supplied to the heater; at least one detachable element that is attachable to and detachable from an inner space or an outer space of the aerosol generating device; and a plurality of geomagnetic sensors for detecting changes in the strength of an internal magnetic field of the aerosol generating device, wherein the controller detects detachment of the detachable element based on a detection result from at least one of the plurality of geomagnetic sensors.
