AIR AROMATIZING APPARATUS Russian patent published in 1995 - IPC

FIELD: medical engineering. SUBSTANCE: this air aromatizing apparatus includes housing 2 containing coaxially positioned casing 13 which in turn houses helical evaporator 5 and heater 6 connected to power source 8 via switching unit 7. Disposed above housing 2 is aromatizing stock supply unit 1, which is batcher 14, whose outlet passage combined with upper edge of screw. Batcher 14 actuates working member 15 and associated control unit 16 provided with driving rod 23 which has stop and is made movable in guides. Control unit 16 includes ratchet-and-pawl mechanism 29 and screw mechanism 27. Another version of control unit may be made up of two Z-shaped curved pivotally connected members located in its middle portion, contacting with driving rod stop and at the same time gripping working member by jaws. Working member is made in the form of flexible shell having outlet passage. Batcher 14 is additionally provided with switching member 40 that is electrically connected to control input of switching unit 7 and timer 18. Second input of timer 18 is connected to selector employed for presetting duration of single functioning cycle for device 19. Output of timer 18 is additionally connected to control unit related to batcher 16 via interlocking member 20 used to energize electromagnet having moving member. EFFECT: disclosed apparatus allows matching rate of consumption of aromatizing stock with intensity of evolution of volatiles. 11 cl, 4 dwg
