Abstract
A shower head with an inner core includes a shower head body, an inlet valve core assembly, an inner core assembly, and a water outlet panel. The inlet valve core assembly is fitted in an inlet valve chamber of the shower head body. A return spring of the inlet valve core assembly abuts against an inner wall of the inlet valve chamber and one end of an inlet valve core. The inner core assembly is detachably fitted inside an inner core chamber. The water outlet panel is connected with the shower head body and provided with a functional water chamber communicating with a water outlet passage. The shower head can prevent the inner core assembly from flying out of the inner core chamber due to the impact of the water flow to hurt the user.
