    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.

    Abstract: A gas detecting device includes a casing, a gas transportation actuator, a gas detector and a driving module. The casing has an inlet, an outlet and an accommodation slot. The inlet and the outlet are in fluid communication with each other, and the accommodation slot is disposed under the inlet and is in fluid communication with the inlet. The gas transportation is disposed within and seals the accommodation slot, and the gas transportation actuator is enabled to introduce air thereinto through the inlet and discharge the air through the outlet. The gas detector is configured to detect an amount of a specific gas in the air introduced through the inlet. The driving module controls the actuations of the gas transportation actuator and the gas detector, so that the gas detector detects the amount of the specific gas in the air.

    Abstract: A VOC detecting and warning method is provided. Firstly, an actuating-and-sensing module having a gas transportation actuator and a gas sensor is provided. Then, the gas transportation actuator guides a specified amount of gas to the gas sensor for obtaining plural monitored values, each of which is generated according to a result of detecting volatile organic compounds of the gas in each monitoring time interval by the gas sensor. All the monitored values obtained in a unit time period are added together, so that an accumulated comparison value is obtained. If the accumulated comparison value is determined greater than an injury threshold defined according to the VOC inhalation amount affecting the health of a human body, the actuating-and-sensing module issues a warning notification to notify the user to take protective measures.

    Abstract: A breast pump includes a main body, a breast milk suctioning shield, and one or more air pumps. The breast milk suctioning shield is assembled in an accommodation space of the main body and detachably connected to the main body. A front end of the breast milk suctioning shield has a breast shielding portion, and a nipple passage extends from a rear end of a center portion of the breast shielding portion. One or more deformable members and a non-deformable supporting member are assembled with an annular connection portion located between the breast shielding portion and the nipple passage. The air pump has an intake port and an exhaust port. The intake port is controlled by a first valve controller to suction the nipple passage and generate a negative pressure, and the exhaust port is controlled by a second valve controller to inflate or deflate the deformable member.

    Abstract: A driving circuit of fluid pump module includes a microprocessor, a primary boost circuit, and a pump driving circuit is provided. The microprocessor receives an output signal with a large-width variable rectangular waveform, a driving voltage, a first detection current-feedback signal, and a second detection current-feedback signal. The primary boost circuit converts an inputted driving voltage into a direct current with a certain high voltage. The pump driving circuit receives the certain high voltage and is connected with the microprocessor to receive the voltage control signal and the pulse-width modulation (PWM) signal. The secondary boost circuit receives the certain high voltage to boost the certain high voltage into a working voltage for the fluid pump. The operation driving circuit receives the working voltage and provides the pulse-width modulation signal for the fluid pump through the second detection current-feedback signal.
