Description

Technical Field

[0001] The present invention belongs to the technical field of fire detection, and in particular relates to a fire detection sensing device and a fire alarm system having the same. Background Art

[0002] Fire refers to a disastrous combustion phenomenon that is out of control in time or space. Among various disasters, fire is one of the most frequent and common major disasters that threaten public safety and social development. Nowadays, there are many types of fire sensors on the market, but many fire sensors have a high misjudgment rate. When a fire occurs, linear sensing of its temperature and triggering of action signals is one way to reduce its misjudgment.

[0003] Some other fire sensor devices, such as those in outdoor cable trenches, deep water environments, and humid places, are prone to moisture in the circuits inside the fire sensor box, which can easily cause false alarms in fire detectors. Therefore, non-misjudgment sensing detection of fire sensors and sealing of fire sensor devices have become issues that need to be addressed. Summary of the invention

When a fire occurs in the monitored area during use, the ceramic tube absorbs heat, causing the glue poured at the port of the ceramic tube to melt. Then, under the action of the counterweight ball, the conductive ball is controlled to slide along the inner wall of the ceramic tube until the conductive ball and the conductive ring are in contact. At this time, the current detection module and the buzzer are started, and the fire alarm signal and fire alarm information are triggered, thereby solving the problems raised by the background technology.

[0030] Then, in the initial state, the conductive ball 12 is controlled to be located at the bottom of the ceramic tube.

Then, when a fire occurs in the fire detection sensing device, the ceramic tube absorbs heat and causes the glue to melt. Then, under the action of the counterweight ball 13, the conductive ball 12 is controlled to slide along the inner wall of the ceramic tube until the conductive ball 12 and the conductive ring 111 are in contact.
