AI Technical Summary

Technical Problem

Existing indoor formaldehyde and harmful gas monitoring and alarm devices lack a protective storage structure, which makes the sensors and displays easily damaged. They are also susceptible to dust and moisture intrusion when not in use, affecting their lifespan and the accuracy of monitoring data.

Method used

A device comprising a housing, a movable plate, and a monitoring component is designed. The monitoring component is protected by the flipping of the movable plate and the locking of the limiting plate, combined with the carrying rope. The fan blades and impeller driven by the motor are used for air filtration and detection. The air distribution tube ensures that the air is evenly distributed to the detection probe, and the alarm emits an audible and visual alarm.

Benefits of technology

It enables convenient deployment and storage of the device, protects the sensors from damage, ensures the accuracy and lifespan of air detection, provides timely alarms, and enhances the user experience.
