AI Technical Summary

Technical Problem

Traditional smoke detectors lack flexible orientation adjustment capabilities in their gas sampling devices, resulting in a limited gas collection range that affects the accuracy and timeliness of fire warnings. Additionally, dust and other impurities can easily get mixed in, affecting the accuracy of gas analysis, and the dustproof mesh is inconvenient to clean and maintain.

Method used

Design a gas sampling device for a smoke alarm, employing an orientation adjustment mechanism and a filtration mechanism. The orientation adjustment mechanism uses a motor to drive gears and a gear ring to rotate the conduit, enabling flexible adjustment of the gas sampling orientation. The filtration mechanism uses a dustproof net and an easily removable design to prevent dust from entering, ensuring the purity of the collected gas.

Benefits of technology

It enables flexible adjustment of the gas collection direction, improving the accuracy and timeliness of fire early warning, and ensures the purity of gas collection and efficient operation of the equipment through the easy-to-remove dustproof net design.
