  • Patent number: 11278685
    Abstract: An inhaler comprising an elongate housing containing a reservoir of inhalable composition. An outlet for the composition and suction port are provided at one end of the housing. A diaphragm is mounted in the housing defining a suction chamber such that suction on the suction port reduces the size of the suction chamber. An elongate leaf spring is mounted at one end to the housing at the end of the suction chamber opposite to the suction port, and is pivotally mounted at an intermediate portion about a pivot point. A valve element is at the end of the leaf spring opposite to the one end and is biased closed. Suction on the suction port deflects the diaphragm and hence the leaf spring between the one end and the pivot point causing the opposite end of the leaf spring to pivot about the pivot point thereby causing the valve element to open.
