NEGATIVE PRESSURE AIRFLOW-DRIVEN HAIR CLIPPER

WIPO Patent Application WO/2017/211101

A1

A negative pressure airflow-driven hair clipper, comprising a casing (1) and a hair clipping blade (2) mounted at a head portion of the casing. A negative pressure turbine airflow channel (3) and a hair drawing airflow channel (4) isolated from each other are formed within the casing. The negative pressure turbine airflow channel is provided with a negative pressure turbine air-operated machine (5) connected to the hair clipping blade and capable of driving, during motion thereof, the hair clipping blade to clip hair. A hair drawing opening (4a) of the hair drawing airflow channel is provided nearby the hair clipping blade. A rear portion of the casing is connected to a flexible airflow tube in gaseous communication with both the negative pressure turbine airflow channel and the hair drawing airflow channel. The other end of the flexible airflow tube is connected to a vacuum machine capable of generating a negative pressure airflow to drive the negative pressure turbine air-operated machine to rotate. The hair clipper of the present invention has a simple structure, is safe and environmentally friendly, and enables, by means of action of a negative pressure airflow, both driving a hair clipping blade to perform hair clipping and collecting the clipped hair, thus ensuring tidiness of the environment.
