AI Technical Summary

Technical Problem

The existing smoke detectors and fire alarm systems are installed separately, requiring additional openings for electrical points on the decorative ceiling, which results in a poor aesthetic appearance.

Method used

Design a smoke detector with broadcast function. The voltage level is separated by a pre-embedded box and a partition. The detector module and the broadcast module are installed in one unit. The magnetic clamp and permanent magnet drive the voice coil to generate sound waves. Combined with the paper cone and dust cover structure, the amount of construction pipeline engineering is reduced.

Benefits of technology

This design allows for the combined installation of smoke detectors and fire alarm systems, optimizing costs, improving aesthetics, extending service life, reducing electrical openings, and enhancing overall equipment performance.

Abstract

The utility model discloses a smoke detector with a broadcasting function, which comprises a pre-embedded box, a wall body is arranged on the outer side of the pre-embedded box, a partition plate is arranged in the middle of the pre-embedded box, one side of the pre-embedded box is connected with a first wiring pipe in a penetrating manner, and the other side of the pre-embedded box is connected with a second wiring pipe in a penetrating manner; the smoke detector with the broadcasting function is provided with the partition plate, different voltage grades can be separated through the partition plate in the middle, the fire alarm bus is connected into the smoke detector through the second wiring pipe, the broadcasting line is connected into the broadcasting module through the first wiring pipe, and after the equipment base is installed, the detector module and the broadcasting module are installed respectively. The detector module and the broadcast module are installed in a combined manner, so that the construction and pipeline design work amount is reduced, the cost is optimized, and the situation that the smoke detector and the fire-fighting broadcast are installed separately, so that the number of electrical point positions on the decorative top surface is increased, and the attractive effect is poor is avoided.
