AI Technical Summary

Technical Problem

When existing intelligent fire smoke detectors detect smoke, the smoke needs to directly enter the containment space of the detection module, which makes it difficult to improve the detection sensitivity. In addition, smoke and dust tend to settle and accumulate in the detection module, affecting the service life and stability of the device.

Method used

An intelligent fire smoke detector with self-cleaning function was designed. Through the assembly structure and the swirling smoke drive structure, and by using the wind chime drive component and the intermediate transmission component, the rapid flow of smoke and the self-cleaning of the detection module are realized, ensuring that the smoke enters quickly and is discharged in time, reducing the accumulation of smoke dust.

Benefits of technology

It improves flue gas entry efficiency, enhances detection sensitivity, reduces dust settling and accumulation, extends the service life of the device, and is energy-saving and environmentally friendly.
