PURPOSE: A recyclable sprinkler head is provided to reduce inconvenience of replacement of the entire head and thus, to improve cost effectiveness, and to expand applicability of the sprinkler to a wider range of temperature. CONSTITUTION: The recyclable sprinkler includes a frame(1); a deflector(2) installed at the lower end of the frame(1); and a cylindrical operator installed at a spillway(4) and having a built-in bimetal(10) functioning as a heat sensitizing agent. A spring(8) is attached to the end of the operator. Also, at the lower end of the frame(1) is a fixer(5), a tester(6), and a spring. A rubber packing(9) is placed at a position where the spillway(4) and the lower end of the frame(1) meet to ensure that pressurized water does not leak.
