Abstract

A control led odor generator, comprising a central processing unit, at least one micropump unit, a sensor unit and a fan. The micropump unit is housed in a casing containing odorous fluid and has a micropump array for ejecting the odorous fluid in tiny droplets. The central processing unit regulates operation of the micropump unit, allowing to control timing quantity and mixture of spread odor. The sensor unit provides the central processing unit with environmental data, like temperature, air density and humidity, as well as human body states for controlling the micropump unit. Environmental changes are followed by a change of spraying of odor, and varying taste and demand are adapted to.

Claims

1. A controlled odor generator, comprising:

a central processing unit; and

at least one micropump unit, each having a casing and a micropump array;

wherein said central processing unit controls ejecting of a fluid in tiny droplets by said at least one micropump unit for changing odor in surrounding air.

2. A controlled odor generator according to claim 1, further comprising a sensor unit having a plurality of sensors for sensing data, such as environmental temperature, humidity and lighting as well as human body temperature and heartbeat, said data being used to control operation of said at least one micropump unit.

3. A controlled odor generator according to claim 1, wherein said casing of said at least one micropump unit is filled with odorous fluid.

4. A controlled odor generator according to claim 1, wherein for each of said at least one micropump unit said micropump array is connected with said casing, allowing to vaporize and eject odorous fluid stored in said casing.

5. A controlled odor generator according to claim 1, further comprising a fan for evenly distributing odorous fluid ejected by said at least one micropump unit.

6. A controlled odor generator according to claim 1, wherein said central processing unit receives sensor signals for controlling said at least one micropump unit.

7. A controlled odor generator according to claim 1, wherein said at least one micropump units eject odorous fluids of various kinds.

8. A controlled odor generator according to claim 1, wherein for each of said at least one micropump units said casing is detachable from a base for easy replacement.

9. A controlled odor generator according to claim 1, wherein for each of said at least one micropump units said casing is integrated with said micropump array.

10. A controlled odor generator according to claim 1, wherein for each of said at least one micropump units said casing is separate from said micropump array, being connected by a tube with said micropump array.

11. A controlled odor generator according to claim 1, wherein said central processing unit controls time cycles, quantities and mixtures of odorous fluid to generate odors according to individual taste and demand.

12. A controlled odor generator according to claim 1, used in conjunction with equipment for visual and acoustic effects for additionally generating odor.

13. A controlled odor generator according to claim 1, used in conjunction with medical equipment, allowing a patient to inhale medicine at well-defined times.

14. A controlled odor generator according to claim 1, wherein said central processing unit is connected with a control panel.
