Title:
APPARATUS FOR GENERATING VARIABLE AIRFLOW AND MASSAGER
Document Type and Number:
WIPO Patent Application WO/2023/123592
Kind Code:
A1
Abstract:
An apparatus for generating a variable airflow and a massager. The apparatus comprises a cavity (6) provided with a chamber (67), the cavity (6) being provided with an air nozzle (63) in communication with the chamber (67), and the bottom of the cavity (6) being provided with an air driving mechanism causing air in the chamber (67) to flow and form an aggregated airflow at the air nozzle (63). The inner wall of the cavity (6) is a curved surface. Because the inner wall of the cavity (6) is a curved surface tapering towards the air nozzle (63), the curved inner wall gathers and compresses the airflow, and when the cavity (6) becomes smaller and compressed pressed, air in the cavity (6) is pressed towards an opening (64) to be rapidly gathered and compressed, resulting in a sharply increased pressure intensity, forming a jet airflow at the air nozzle (63). When used for massaging, the airflow can produce a flapping massage effect on the human body. When the volume of the cavity (6) is increased, the air at the air nozzle (63) is rapidly pulled away to quickly generate a negative pressure and suction the human body, achieving suction massage. When the area of the air driving mechanism is larger than that of the opening (64), air in a large area can be compressed, and the massage effect of the air flapping massage or the suction massage of the massager is improved.
