Abstract: An indoor air cleaning system with disconnection detecting and preventing mechanism includes a gas filtration device and a cloud computing server. The gas filtration device is disposed in an indoor field and including a fan, a filter element, a gas detector and a driving control element. The gas detector detects air pollution, outputs air pollution information. The cloud computing server receives the air pollution information via IOT communication, stores the air pollution information to form a big data database, performs an intelligence computing for comparison based on the big data database, and issues a control command to enable the fan. When IOT communication is judged as disconnected, the gas detector autonomously computes and compares the air pollution information and issues the control command to enable the fan, thereby reaching a gas state of the indoor field to a cleanroom class with a level of air pollution close to zero.

Abstract: A portable gas detecting device includes at least one detecting chamber, at least one gas sensor and at least one actuator. The gas sensor is disposed in the detecting chamber and configured for monitoring gas inside the detecting chamber. The actuator is disposed in the detecting chamber and includes a piezoelectric actuator. When an actuating signal is applied to the piezoelectric actuator and the piezoelectric actuator generates a resonance effect, the gas outside the detecting chamber is introduced into the detecting chamber for sampling. The actuator is driven by an instantaneous sampling pulse to control a trace of gas to flow into the detecting chamber for forming a stable airflow environment. In the stable airflow environment, a gas molecule is dissolved in or bonded to a reaction material on a surface of the gas sensor for reacting.

The gas outlet nozzle and the gas outlet cavity are in communication with each other. Each flow-guiding pedestal includes a main plate, a protruding frame and a chamber frame. The main plate includes a recess and a communicating aperture in communication with the recess. The gas pumps are disposed inside the chamber frames of the flow-guiding pedestals, respectively. The gas outlet cover covers the flow-guiding pedestals and is connected to the protruding frames, whereby plural convergence chambers are defined and are in communication with the gas outlet cavity. Consequently, the gas is transported through the recesses, the communicating apertures, the convergence chambers and the gas outlet cavity sequentially, and finally is discharged out from the gas outlet nozzle.

The measuring channel is used for allowing a target liquid to flow therethrough. The at least one sensor is disposed within the measuring channel for measuring the target liquid. The at least one actuating device is in communication with the measuring channel for transferring the target liquid. The filtering element is disposed within the measuring channel and arranged adjacent to the at least one actuating device for filtering the target liquid. If a measuring result of the sensor indicates that a monitored value of the target liquid is abnormal, the actuating device is enabled to transfer the target liquid. Consequently, the target liquid is filtered by the filtering element.
