Description

Novel smoke detector

Technical Field

The utility model belongs to the technical field of smoke detectors, and particularly relates to a novel smoke detector.

Background

In the traditional fire control field, smoke detectors determine fire by detecting the concentration of smoke particles entering a detector maze. Smoke detectors have been the most common and effective fire detection sensor, and are widely visible in everyday life.

With the great development of new energy automobiles, various automobile accessory industries are driven. The automobile battery is a core component of a new energy automobile, is used for storing energy and provides main work of automobile driving electric energy. However, the automobile battery has a complex process and high production requirement, and any careless mistakes in the production process can cause abnormal heating and ignition of the battery. The automobile battery must be aged for a long time before leaving the factory, and in the aging process, the defective battery can generate heat and fire. The battery generally starts to smoke and then fires at the beginning of the fire. Therefore, many battery manufacturers currently install smoke detectors in the aging racks during the aging process of the battery products to detect the initial fire. However, the space in the shelf is limited, and the common smoke detector on the market is generally about 50mm (generally 46-55 mm), as shown in fig. 5: which presents difficulties for field installation.

In order to solve the practical problem, a smoke detector with smaller thickness and suitable for being installed in a battery aging warehouse shelf is developed.
