KR-102962314-B1 - fire detector of fire indication of cap-opening

Abstract

The present invention generally relates to a fire detector that detects smoke or heat and issues a fire alarm. In particular, the present invention relates to a cap-opening fire indicator type fire detector configured such that, while issuing a fire alarm due to smoke or heat, a solenoid member inside the fire detector forcibly opens a cap member, thereby allowing the user to intuitively identify the fire detector that initially issued the fire alarm. According to the present invention, by configuring the external cap member of the fire detector to open when smoke or heat is detected and a fire alarm is issued, the user can immediately identify the fire detector to be inspected and can identify the fire detector to be inspected even after the fire alarm operating power is cut off, thereby offering the advantage of effectively managing multiple fire detectors installed in a building. Furthermore, the present invention has the advantage of reducing the possibility of operational errors by configuring it with a solenoid member that uses current as the operating source, rather than a complex electronic control method. Additionally, the present invention has the advantage of low installation costs because it can be applied by replacing existing fire detector products on a one-to-one basis.

Description

fire detector of fire indication of cap-opening The present invention generally relates to a fire detector that detects smoke or heat and issues a fire alarm. In particular, the present invention relates to a cap-opening fire indicator type fire detector configured so that a user can intuitively identify the fire detector that first issued the fire alarm by forcibly opening a cap member while issuing a fire alarm due to smoke or heat by a solenoid member inside the fire detector. A fire detector is a device that detects smoke or heat and issues a fire alarm, thereby preventing casualties and enabling early fire suppression. Under the Fire Prevention Act, fire detectors must be installed in specific spaces within buildings. According to the National Fire Agency's 2020 statistics on false fire reports, malfunctions in automatic fire alarm systems and emergency alarms accounted for 41.5% of the total 112,137 cases. Additionally, statistics on 119 life safety activities show a steady increase in the number of dispatches for false alarms ("fire detectors activating due to factors other than fire") since 2016. Looking at relevant statistics from 2018, fire detectors accounted for 83.9% of the firefighting equipment causing false alarms, and 62% of the causes were due to poor construction, poor management, equipment aging, or errors, indicating a need for equipment replacement. The response sequence for a fire alarm involves first checking the receiver (verifying the fire indicator light and zone indicator light), then proceeding to the relevant area to confirm whether an actual fire has occurred. If confirmed to be a false alarm, deactivate the sound system and eliminate the cause. Subsequently, restore the fire alarm receiver and sound system, and check the status of the switch warning light. In principle, when a siren sounds within a building due to a false alarm caused by a fire detector malfunction, the user is responsible for promptly locating the faulty detector and eliminating the cause, such as by replacing it. However, in reality, if the faulty detector cannot be located because the LED is difficult to identify or the LED itself is defective, users often cut off the power to the fire alarm or turn off the sound device due to concerns such as complaints regarding the siren noise. When a user cuts off the power to a fire alarm, the LED status of the faulty fire alarm is also reset, making it impossible to locate the faulty fire detector. This results in repeated false alarms caused by fire detector malfunctions. When such false alarms occur repeatedly, building occupants become desensitized to fire alarms, and users even turn off the fire alarms, which leads to large-scale casualties in the event of an actual fire. The conventional research direction regarding this problem is to reduce the rate of false alarms. The present invention presents a mechanical configuration that enables the clear identification of faulty fire detectors when a false alarm occurs. [Fig. 1] is an overall configuration diagram of a cap-open fire indicator type fire detector according to the present invention. [Fig. 2] is an internal block diagram of a cap-open fire indicator type fire detector according to the present invention. [Fig. 3] is an example diagram of the operation of a fire detector according to the present invention. The present invention will be described in detail below with reference to the drawings. In describing the present invention, detailed explanations of parts that overlap with the prior art may be omitted. [Fig. 1] is an overall configuration diagram of a cap-open fire indicator type fire detector according to the present invention, and [Fig. 2] is an internal block diagram of a cap-open fire indicator type fire detector according to the present invention. The fire detector (100) according to the present invention, when it detects a fire by smoke or heat, in addition to performing a normal fire alarm operation, has a function to intuitively notify the user of the fact that it has detected a fire by opening a cap. Through this, when a false fire alarm occurs, the user can immediately remove the cause of the false fire alarm, thereby enabling the fire alarm system to be stably restored. To this end, the fire detector (100) according to the present invention comprises a base member (101), a cap member (102), a cap connecting member (103), a cap fastening member (104), a fire detection member (110), and a cap opening member (120). First, the base member (101) is fixed to a specific installation point, such as a building ceiling, as an element constituting the base body of the fire detector (100). The cap member (102) is a component that constitutes the lid body of the fire detector (100). The cap connecting member (103) is an element that fixes one side of the cap member (102) to one side of the base member (101). The cap connecting member (103) may be composed of a latch mechanism. The cap fastening member (104)
