Title:
INHALATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/206340
Kind Code:
A1
Abstract:
Disclosed is an inhalation device, which, by means of a simplified structure, reduces the manufacturing difficulty and cost, and ensures the use effect. In the inhalation device, a filter member closely fits to a capsule placement opening, and when a mouthpiece is clamped to a cover plate, a mesh portion is integrally located in a capsule compartment. Therefore, when a medicinal powder is inhaled, airflow can better pass through the mesh portion under the action of a negative pressure to flow in an ideal flow direction, thereby ensuring the medicinal powder to be effectively inhaled.
