International ClassH01L 041/08Foreign Application Priority Data1986-08-11 DEAbstractAn ultrasonic pocket-size atomizer comprises a housing including a first portion and a second portion detachably connected thereto. A vibration generation mechanism is mounted liquid-tight in the first portion of the housing for generating an oscillation with a frequency between 1 and 5 Mhz. The vibration generation mechanism includes a piezoelectric assembly and an electronic circuit operatively connected to the assembly for energizing the assembly and causing the assembly to vibrate. A power source including a storage battery is removably and rechargeably disposed in the first portion of the housing for supplying electric current to the electronic circuit. A cartridge is provided for containing liquid to be atomized, the cartridge being movably disposed in the second portion of the housing. An activation mechanism is provided for automatically activating the electronic circuit upon motion of the movable section of the cartridge, the activation mechanism including a magnet attached to the movable section of the cartridge so as to move therewith. The activation mechanism further includes a switch operatively connected to the electronic circuit and operable by the magnet upon a shift in the position thereof during motion of the movable section of the cartridge.Field of SearchPressing means detailSpecific material or composition Oval track Roller or ball element Horn or transmission line Support Piezoelectric element or electrode Motor producing continual motion Sandwich or Langevin type Material or material property Positions an object Armature Output member detail Stator Traveling wave motor Direct mechanical coupling Detector (e.g., sensor) Acoustic wave type generator or receiver Langevin or pencil type motor Device performs work on an object (e.g., welding, cutting) Eliptical motion at fixed point (i.e., walking) or Ratchet and Pawl motor Diaphragm Combined with resonant structure Input circuit for mechanical output from piezoelectric element By electric transducer (e.g., piezoelectric crystal) LIQUID MEDICAMENT ATOMIZER OR SPRAYER Ultrasonic | |
