1. A health monitoring device having gas detection function and allowing users to examine their own health conditions at any time, wherein the health conditions are weight, body fat, blood pressure, heartbeat, or sleep quality, and the health monitoring device comprises:
a main body having at least one inlet, at least one outlet and a gas detection module, wherein the gas detection module comprises a piezoelectric actuator and at least one sensor, wherein gas is inhaled into the main body through the inlet by the piezoelectric actuator, is discharged out through the outlet, and is transported to the at least one sensor to be detected so as to obtain gas information, wherein the piezoelectric actuator comprises:
a gas-injection plate comprising a plurality of connecting elements, a suspension plate and a hollow aperture, wherein the suspension plate is permitted to undergo a bending deformation, the plurality of connecting elements are adjacent to a periphery of the suspension plate, and the hollow aperture is formed at a center of the suspension plate, wherein the suspension plate is fixed through the plurality of connecting elements, and the plurality of connecting elements are configured for elastically supporting the suspension plate, wherein a flowing chamber is formed between the gas-injection plate and the bottom surface of the gas-guiding-component loading region, and at least one vacant space is formed among the plurality of connecting components and the suspension plate;
a chamber frame carried and stacked on the suspension plate;
an actuator element carried and stacked on the chamber frame for being driven in response to an applied voltage to undergo the bending deformation in a reciprocating manner;
an insulation frame carried and stacked on the actuator element; and
a conductive frame carried and stacked on the insulation frame,
wherein a resonance chamber is formed among the actuator element, the chamber frame and the suspension plate, wherein when the actuator element is enabled to drive the gas-injection plate to move in resonance, the suspension plate of the gas-injection plate is driven to generate the bending deformation in a reciprocating manner, the gas is inhaled through the vacant space, flows into the flowing chamber, and is discharged out, so as to achieve gas transportation.
