Abstract
A temperature alarm device for a breathing apparatus is described, comprising an air bottle (1) with a main valve (2) to which is connected a hose (3) for supply of air from the air bottle (1) via a reduction valve (4) to a breathing mask (5), wherein the temperature alarm device comprises a temperature controlled sound transmitter that emits a sound when the temperature of the surroundings exceeds a pre-defined temperature. A breathing apparatus comprising this temperature alarm device is also described.
Claims10
A temperature alarm device for a breathing apparatus comprising an air bottle (1) having a main valve (2) to which is connected a hose (3) for supply of air from the air bottle (1) via a reduction valve (4) to a breathing mask (5), where the temperature alarm device comprises a temperature controlled sound transmitter (8) that emits a sound when the temperature of the surroundings exceeds a predefined temperature, characterised in that the sound transmitter (8) comprises a whistle that is directly or indirectly connected to the air bottle (1), as well as a temperature controlled valve (9) that opens above a given temperature in order to allow air from the air bottle to flow through the whistle and thus produce a sound.
A temperature alarm device according to any of the preceding claim, characterised in that the temperature controlled valve (9) is insulated in order to delay the tripping of the sound emission.
A temperature alarm device according to any of the preceding claims, characterised in that the sound transmitter (8) and the temperature controlled valve (9) ane placed at a good distance from the main valve (2) of the air bottle.
A breathing apparatus comprising an air bottle (1) with a main valve (2) to which is connected a hose (3) for supply of air from the air bottle (1) via a reduction valve (4) to a breathing mask (5), the breathing apparatus comprises a temperature controlled sound transmitter (8) that emits a sound when the temperature of the surroundings exceeds a predefined temperature, characterised in that the sound transmitter (8) comprises a whistle directly or indirectly connected to the air bottle (1), as well as a temperature controlled valve (9) that opens above a given temperature in order to allow air from the air bottle to flow through the whistle and thus produce a sound.
