WIPO Patent Application WO/2021/022413
Kind Code:
A1
Abstract:
Disclosed is a massage device for a local part of a human body. The massage device comprises a shell (1), wherein a first cavity (2) is formed inside the shell (1); the shell (1) is provided with an opening (20) capable of covering the local part of the human body; the opening (20) is in communication with the first cavity (2); a first drumhead-like membrane (3) and a driving mechanism (4) used for driving the first drumhead-like membrane (3) to vibrate in a reciprocating manner are arranged inside the shell (1); the first drumhead-like membrane (3) covers the bottom of the first cavity (2), and the first drumhead-like membrane (3) and the first cavity (2) are connected in a sealed fit manner; when the first drumhead-like membrane (3) vibrates in the reciprocating manner, air pressure in the first cavity (2) changes along with the vibrations, and repeated suction massage is then carried out on the local part of the human body; the driving mechanism (4) comprises a flexible second drumhead-like membrane (40) and an extrusion mechanism (41) for extruding the second drumhead-like membrane (40); a second cavity (42) is formed on an inner side of the second drumhead-like membrane (40); and when the extrusion mechanism (41) repeatedly extrudes the second drumhead-like membrane (40), the first drumhead-like membrane (3) vibrates along with the change in air pressure in the second cavity (42). The massage device for the local part of the human body can indirectly conduct vibration waves and has a suction massage effect, thereby improving the comfort of use, and the user experience is therefore better.
