An electromagnetic massage device applicable to a bathtub or a pool comprises an integrally formed fixed seat (1), suited to be fixed in a mounting hole on a wall (20) of the bathtub or the pool; a lock nut (8), matched with an external thread (19) on a circumferential wall on the lower end of the fixed seat (1), so as to fasten the lower end of the fixed seat (1) to the external surface of the wall (20) of the bathtub or the pool; a rubber sleeve (7), the top portion of which protrudes outwards, and the bottom portion of which has an annular flange, the annular flange being adhered to an annular base plate (15) of a concave cavity (14) of the fixed seat (1), so as to seal an upper end opening of the fixed seat (1); a conductive coil (4), arranged in an annular cavity (12) of the fixed seat (1), and encapsulated by an upper magnetic conduction cover (6), a lower magnetic conduction cover (9), and a magnetic conduction shell (5); and a beating head (2) and an armature (3) that are fixedly connected together and mounted in a guide cavity (11) of the fixed seat (1), the beating head (2) and the armature (3) sliding back and forth in the guide cavity (11) under the effect of the electromagnetic field generated by the conductive coil (4). The electromagnetic massage device provides high kinetic energy, a long service life, and a desirable massage effect; meanwhile, no pipeline is soaked, thereby facilitating implementation of intelligent control.
