Flow rate controller

A flow rate controller for adjusting a flow rate of a shower facility, comprising:

• a pipe body, comprising a channel, a water supply opening and a water outlet opening, wherein the water supply opening is adapted to connect to a water supply pipe, and the water supply opening communicates with the water outlet opening through the channel;
• and
• a control assembly, comprising a fixed member and a rotatable member, wherein the fixed member is fixedly positioned in the pipe body, and includes a first flow hole;
• the rotatably member is coaxially and rotatably connected to the pipe body, so that the rotatably member is rotatable relative to the pipe body, and the rotatably member includes a plurality of second flow holes and a plurality of adjusting positions, wherein the second flow holes have different hole sizes to each other, and each of the adjusting positions is respectively corresponding to the corresponding one of the second flow holes;
• when the rotatable member rotates to one of the adjusting positions, the corresponding second flow hole overlaps the first flow hole;
• wherein the rotatable member comprises an elastic positioning pin, and pipe body comprises a plurality of positioning recesses;
• each of the positioning recesses is corresponding to the corresponding one of the adjusting positions of the rotatable member;
• when the rotatable member rotates to one of the adjusting positions, the elastic positioning pin goes into the corresponding positioning recess, and the corresponding second flow hole overlaps the first flow hole.
