Patent abstract
A concealed fire sprinkler includes a main body, an arm extending along the main body and a receiving slot formed on the arm. A bottom cover is fixed by the arm at bottom of the main body. An elastic component is received in the receiving slot. Two ends of the elastic component contact with the arm and the bottom cover. Accordingly, the conventional problems that the temperature sensing speed of concealed fire sprinklers is not capable of increasing rapidly can be solved.
