<p>Disclosed is a fire detecting and control apparatus, comprising a base (4), a switch (3) provided in an inner cavity of the base (4), and a frame (1) provided above the base (4), wherein the top end of a thermosensitive glass bubble (2) is supported by means of the frame (1), and the bottom end extends as far as the upper surface of the switch (3) to keep the switch (3) in a disconnected state. Using a heat-sensitive glass bubble to control a multi-contact switch, there is no need to provide an external power supply, overcoming the problem in the prior art of a detector being easily affected by external interference or misinformation due to voltage fluctuation. The reaction is fast and reliable, the invention is suitable for application in different places, and will not be affected by air currents, dust, water vapour, corrosive gases or light, thus having a wider scope of application. The apparatus can combine the functions of detecting and control within one body, has a simple and reliable structure and is convenient to assemble.</p> |
