Abstract

The invention relates to a smoke alarm device for fire protection. The smoke alarm device comprises an alarm device body, a housing, a protective cover, smoke inlet holes, a pest control cover, a small fan, and a hollow-out partition board. The housing is arranged at the outer side of the alarm device body; and the protective cover is fixedly connected to the lower end of the housing. Five to sixsmoke inlet holes are formed in the lower side of the protective cover; the small fan is arranged above the smoke inlet holes and is fixedly installed at the lower side of the hollow-out partition board; a smoke sensor is arranged above the hollow-out partition board; and a control device is arranged at the right side of the smoke sensor. Storage batteries are arranged t the two sides of the smokesensor and the control device; and a relay is arranged above the storage batteries. According to the smoke alarm device, the sensing information to the smoke by the smoke sensor is transmitted to thecontrol device by a sensing line; the control device controls an automatic on-off switch to connect the circuit; and the relay controls the whole circuit to ensure the normal working of all electrical appliances. Besides, the alarm device and a flashlight inform people of the fire in a warning manner, so that prevention is carried out timely.

Description

technical field [0001] The invention relates to the technical field of fire-fighting equipment, in particular to a smoke alarm device for fire-fighting. Background technique [0002] Smoke alarm, also known as fire smoke alarm, smoke sensor, smoke sensor, etc., is powered by the bus, connected to the fire alarm controller and communicated to form an alarm system. Smoke alarm devices are generally called smoke detectors. With the improvement of people's living standards and fire awareness, smoke alarms have been widely used in people's lives. [0003] The existing smoke alarms are inconvenient to install and use, and it is not convenient to maintain the alarms. Moreover, the alarm design is not comprehensive enough, the alarm effect is not good, and the sensitivity is not high, causing various consequences and cannot adapt to the current development trend. , does not have the disadvantage of insect-proof and dust-proof effect. In view of the above problems, it is urgent to ...
