Hair drying device

Abstract

A hair dryer including a blower and a dryer head having a narrow elongated nozzle shaped to generate airflow in the form of a thin blade of air. The hair dryer includes an airflow evening structure functionally coupled to the nozzle that more evenly distribute airflow of the thin blade of air. The airflow evening structure is a sleeve rotatably coupled about the nozzle and includes a plurality of diversely shaped nozzle masks disposed about the sleeve, each shaped to restrict airflow through the nozzle in varying modes.

AI Technical Summary

Benefits of technology

The present invention is a hair dryer that aims to solve the problems and needs of the current art. The invention includes a narrow elongated nozzle that generates airflow in the form of a thin blade of air, and a second nozzle that is oriented substantially orthogonal to the narrow elongated nozzle. The hair dryer may also include an airflow equalization structure that helps to evenly distribute airflow. The invention may also include a sleeve that is rotatably coupled about the nozzle and has a plurality of diversely shaped nozzle masks to restrict airflow in various modes. The invention may also include a vane structure that directs airflow to regions of the nozzle with reduced airflow. Overall, the invention provides a more effective and efficient solution for hair drying and styling.

Problems solved by technology

Only a small proportion of the molecules meet these criteria, so the rate of water evaporation is limited.

These result in reduced drying time and comfort during and after drying.

The inventions heretofore known suffer from a number of disadvantages which include being limited in use, being limited in application, being difficult to use, being unable to straighten hair, being limited in motion, being limited in adjustability, failing to provide optimal settings, being too heavy, being too noisy, causing harm to stylists through repeated use, failing to produce sufficient airflow, failing to sufficiently heat air, being inflexible, being awkward to use, producing noise at an undesired high frequency, being unable to condition air with additives, causing the body of the hair dryer to get too hot, being single use / purpose, not permitting precise adjustment of the shape and / or direction of the heated airstream, not permitting a velocity profile of the heated air stream to be precisely adjusted, having an air stream that is too hot, not having selectability in the direction out of the device where the heated air stream exits, not properly mixing air in the air stream, not having substantially uniform airflow, having too slow a response to heating and cooling setting changes, not having a balanced handle, being too likely to set off a circuit breaker, causing strain to stylists using the dryer, being noisy and having too many parts.
