<p>A powder material discharging device (1) including a powder material storage chamber (2) having a discharge port in the lower region, and a diffusion chamber (4) connected to the discharge port of the powder material storage chamber through an elastic membrane (3) having a hole (3a), wherein air pulsation waves are fed into the diffusion chamber (4) through an air pulsation wave inlet port (4a) to force the elastic membrane (3) into vibration, and opening and closing the hole (3a) causes a powder material stored in the powder material storage chamber (2) to fall down into the diffusion chamber, in which it is mixed with the air pulsation waves and diffused, so that the powder material diffused by air is discharged through a discharge port (4b) formed in the diffusion chamber, the air pulsation wave inlet port (4a) being disposed in a position below the diffusion chamber (4) and in a direction tangential to the inner peripheral surface of the diffusion chamber or in a direction equivalent thereto while the discharge port (4b) is disposed in a position above the diffusion chamber (4).</p> |
