1. A massage device, comprising:
a fixing casing; and
an air suction and release driving assembly fixed in the fixing casing, wherein said air suction and release driving assembly comprises:
a chamber body;
a plug movably disposed in said chamber body to form a first chamber; and
a driving unit coupled to said plug, wherein when said driving unit drives said plug to reciprocate in said chamber body, an air pressure of said first chamber of said chamber body is adjusted, so as to allow said massage device to generate suction;
wherein said chamber body forms said first chamber and a second chamber, and when said driving unit drives said plug to periodically reciprocate in said chamber body, volume sizes of said first chamber and said second chamber are adjusted;
wherein said second chamber is provided with an exhaust hole formed on a bottom side of said second chamber opposite the plug, or formed on a surrounding wall of said second chamber adjacent the plug, wherein said driving unit drives said plug to reciprocate in said chamber body to form an inhalation process and an exhalation process, so as to adjust the air pressure in said first chamber, and in said inhalation process, the air in said first chamber is prevented from entering said second chamber, and in said exhalation process, at least a part of the air in said first chamber is allowed to enter said second chamber and is discharged through said exhaust hole;
wherein said plug comprises a plug body having one or more vent holes, and said plug is provided with a flexible valve element which is arranged to allow or prevent said first chamber from communicating with said second chamber through said one or more vent holes;
wherein said plug has a ring-shaped assembly groove under said plug body, and said flexible valve element is disposed in said assembly groove to align with said one or more vent holes, wherein when said plug is driven to move to increase the volume size of said first chamber, said flexible valve element in said assembly groove is tightly attached to a bottom side of said plug body, so that said one or more vent holes are not communicated with said second chamber, thereby allowing said massage device to generate suction, and when said plug is driven to move to decrease the volume size of said first chamber, said flexible valve element in said assembly groove is spaced apart from said bottom side of said plug body to form a gap allowing part of the air in said first chamber to enter said second chamber through said one or more vent holes, so as to be discharged through said exhaust hole.
