Abstract: A particle detecting device is provided. The particle detecting device includes a base and a detecting element. The base includes a detecting channel, a beam channel and a light trapping region. A light trapping structure corresponding to the beam channel is disposed in the 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 particle sensor and the laser transmitter are enabled, the laser transmitter transmits the projecting light source to the beam channel, and the particle sensor detects the size and the concentration of the suspended particles contained in the gas in the detecting channel. The projecting light source is projected on the light trapping structure so that a stray light being directly reflected back to the beam channel is reduced.
