Abstract
A particle detecting device is provided. The particle detecting device includes a base, a detecting element, a micro pump and a drive control board. The base includes a detecting channel, a beam channel and a light trapping region. The detecting element includes a microprocessor, a particle sensor and a laser transmitter. The particle sensor is disposed at an orthogonal position where the detecting channel intersects the beam channel. When the micro pump, the particle sensor and the laser transmitter are enabled under the control of the microprocessor, the gas outside the detecting channel is inhaled into the detecting channel. When the gas flows to the orthogonal position where the detecting channel intersects the beam channel, the gas is irradiated by the projecting light source from the laser transmitter, and projecting light spots generated are projected on the particle sensor for detecting the size and the concentration of suspended particles.
