Abstract
A diffusion chamber block is provided in a block mounting hole A of an inhalant port , and a granular medicine diffusion chamber is formed in the diffusion chamber block . The granular medicine diffusion chamber is formed at a side of the inhalant port with a granular medicine inflow opening A and at a side of a capsule housing hole with a granular medicine outflow opening B. A diffusion chamber in flow passage is provided to communicate an outflow air passageway with the granular medicine inflow opening A, whereas a diffusion chamber outflow passage is provided to communicate the granular medicine outflow opening B with the inhalant port . When inhaling granular medicines in the capsule housing hole via the inhalant port by way of breathing action, there results in counter-flow vortex within the granular medicine diffusion chamber . The counter-flow cortex acts to finely break and atomize massive granular medicines, thus promoting atomization of the granular medicines.
