Description

Technical Field

[0001] The utility model relates to the technical field of smoke sensors, in particular to a novel smoke sensor for mining. Background Art

[0002] Smoke sensors are often called smoke alarms or smoke detectors. They can detect smoke generated during fires. Smoke sensors use photoelectric smoke sensing devices inside and can be widely used for fire safety detection in shopping malls, hotels, shops, warehouses, computer rooms, mines and other places.

[0003] A smoke sensor with reference publication number CN215376501U includes a shell smoke detection component, an air intake grid, a top plate, a mounting plate and a magnetic connection component. The smoke detection component is arranged inside the shell for detecting smoke and alarming. The air intake grid is arranged on the top of the shell. The smoke enters the shell through the air intake grid and is detected by the smoke detection component. The top plate is arranged on the top of the air intake grid. The mounting plate is connected to the shell through a magnetic connection component. The smoke sensor uses the interaction of an L-shaped baffle, a card block, a magnet and an iron block so that the card block can be automatically inserted into the inside of a sliding track during installation without manually rotating the shell. The operation is simple and convenient. Moreover, due to the action of the magnet, the card block can be kept always inside the sliding track so that the card block will not fall off, thereby ensuring the stability of the installation. As can be seen from the above, although the smoke sensor can be well applied, it is usually not convenient to protect the smoke detection component, so that the smoke detection component is easily damaged by external factors, thereby affecting the service life of the smoke sensor, which often troubles people.
