DYNAMIC PRESSURE GENERATION DEVICE AND MASSAGER

WIPO Patent Application WO/2022/247321

A1

A dynamic pressure generation device and a massager. The dynamic pressure generation device comprises a cavity (1) having an opening (1A), a moving component (3) provided in the cavity (1), and a driving mechanism (5) for driving the moving component (3) to reciprocate in the cavity (1); the cavity wall (11, 13) of the cavity (1) is a rigid cavity wall; a gap (1B) is formed between the moving component (3) and the first cavity wall (11); and when the moving component (3) reciprocates in the cavity (1), a positive pressure and a negative pressure that periodically alternate are generated at the opening (1A). When in use, the driving mechanism (5) enables the moving component (3) such as a piston (31) to reciprocate in the length direction of the cavity (1), and when the opening (1A) is in a closed state, the volume of a chamber (60) can be changed by reciprocating of the piston (31), such that the internal air pressure thereof is dynamically changed. The dynamic pressure generation device can generate a dynamic pressure in the chamber (60) and generate a negative pressure at the negative pressure opening, and can be widely applied to products such as massagers.
