Claims

[Scope of utility model registration request]

A heat-sensitive block consisting of at least a heat-sensitive plate and a diaphragm forming a heat-sensitive chamber, a contact spring driven by displacement of the diaphragm due to expansion and contraction of air in the heat-sensitive chamber, and a contact spring formed on the contact spring when the contact spring is driven. A differential heat sensor is equipped with a contact that opens and closes to detect a fire, and a ring that holds the peripheral edge of a heat-sensitive block placed on the body and is welded to the body. A differential type characterized in that a small gap communicating with the outside is formed between the heat-sensitive block and the body, and a gap is also formed between the heat-sensitive block and the body, communicating with the small gap and communicating with the heat-sensitive chamber. heat detector.
