Abstract

A shower head assembly includes a hollow handle and a head. A base plate is engaged with the head and a rotatable member is connected to the head and a fixed plate is secured to the rotatable member. Two tubular members are located between the fixed plate and the base plate. Two springs are received in two respective interiors of the two tubular members and biased between the fixed plate and the base plate. A pattern plate having a plurality of pattern holes is fixed to the rotatable member. A filtering assembly including a cap, an adjusting member with a plurality of ribs, a first filter, a separation ring with a plurality of holes and a second filter. A bolt extends through the filtering assembly and connecting the filtering assembly to the pattern plate. A volume control device is engaged with a connection hole defined through a wall of the handle so as to control water volume through the handle.

Claims

1. A shower head assembly comprising:

a hollow handle and a head connected to an end of the handle, a chamber defined in the head and a connection tube extending from a center of the chamber;

a base plate engaged with the chamber and a through hole defined through a center of the base plate;

a rotatable member having a neck portion extending from a first end thereof and two notches defined in an inner periphery of the rotatable member;

a fixed plate having two protrusions which are engaged with the notches of the rotatable member, two tubular members located between the fixed plate and the base plate, two springs received in two respective interiors of the two tubular members;

a positioning member having a threaded through hole defined therethrough and a screw threadedly extending through the threaded through hole and being connected to the connection tube;

a pattern plate having a plurality of pattern holes and fixed to a second end of the rotatable member, and

a filtering assembly including a cap, an adjusting member with a plurality of ribs, a first filter, a separation ring with a plurality of holes and a second filter, a bolt extending through the filtering assembly and connecting the filtering assembly to the pattern plate.

2. The assembly as claimed in claim 1, wherein a volume control device is engaged with a connection hole defined through a wall of the handle, the volume control device includes a sleeve and a control rod which extends through a passage defined axially through the sleeve so that the sleeve is rotated by rotating the control rod, the sleeve is located in the hollow handle and includes a plurality of wings extending from an outer periphery thereof.

3. The assembly as claimed in claim 1, wherein the through hole of the rotatable member is a rectangular hole and the positioning member includes a rectangular insertion which is engaged with the rectangular through hole of the rotatable member.

4. The assembly as claimed in claim 1, wherein a seal is mounted to an outside of the base plate.

5. The assembly as claimed in claim 1, wherein the rotatable member includes a threaded inner periphery and the pattern plate includes a threaded outer periphery which is connected to the threaded inner periphery of the rotatable member.

6. The assembly as claimed in claim 1, wherein the rotatable member includes a rough outer surface.
