Abstract

An air quality notification device includes an actuating and sensing module and a first communication module. The actuating and sensing module includes a sensor and an actuating device. The sensor is disposed near the actuating device and senses air transmitted by the actuating device to generate air quality information. The first communication module is electrically connected to the actuating and sensing module to receive and transmit the air quality information.

First claim

What is claimed is:

an actuating and sensing module comprising a sensor and an actuating device, wherein the sensor is disposed near the actuating device and senses air transmitted by the actuating device to generate air quality information; and
a first communication module electrically connected to the actuating and sensing module to receive and transmit the air quality information to a second communication module of at least one air quality processing device and a third communication module of an electronic device through the first communication module,
wherein the actuating device is a piezoelectric pump, and the piezoelectric pump comprises:
a fluid inlet plate having at least one inlet, at least one convergence channel and a central cavity defining a convergence chamber, wherein the at least one inlet allows fluid to flow in, and wherein the convergence channel is disposed corresponding to the at least one inlet and guides the fluid from the at least one inlet toward the convergence chamber defined by the central cavity;
a resonance plate having a central aperture and a movable part, wherein the central aperture is aligned with the convergence chamber, and the movable part surrounds the central aperture; and
a piezoelectric actuator aligned with the resonance plate and comprising:
a suspension plate being a square plate structure and having a first surface and an opposite second surface, wherein the suspension plate is permitted to undergo a bending vibration;
an outer frame arranged around the suspension plate;
