Definitions
- the air freshening device for generating a substantially deposition free vapor.
- the air freshening device includes a liquid supply operable to supply liquid material, a wick in fluid communication with the liquid supply, a conductive mesh material operable to retain the liquid material in interstices thereof; and a power supply operable to apply voltage across the mesh material, which acts as a heater, so as to heat the liquid material contained in interstices of the mesh material to a temperature sufficient to at least partially vaporize the liquid.
- the vapor at least partially condenses to form an aerosol.
- the air freshening device is operable to substantially prevent deposition of the vaporized liquid material.
- the power supply includes a supercapacitor that supplies an energy pulse to the heater.
- the air freshening device can also include control circuitry operable to deliver power from the power supply to the mesh in timed heating cycles such that the liquid material is at least partially vaporized after filling interstices of the mesh.
- FIG. 10 is a schematic of exemplary control circuitry, including a heater for the capillary tube and/or mesh material ("capillary” in FIG. 10) and electrical leads ("Caplry +" and "Caplry -”). These leads can be attached at spaced apart locations along a stainless steel capillary tube and/or mesh material in which liquid material is heated by pulsing power through the leads. While the control circuitry may be powered by one or more batteries, such as AA cells, the control circuitry is powered by one battery B.
- the control circuitry preferably comprises a master power switch SW1 , as well as a microcontroller U1 , such as a PIC12F675, manufactured by Microchip.
- the 555 timer circuit output triggered a field effect transistor to apply 5 volts across the heater.
- the heater was mounted on top of the polymeric wick that extended into a reservoir of liquid fragrance material.
- liquid drawn by capillary action to the of the top of the wick filled the interstices of the mesh material that was in contact with the wick. No capillary action moved liquid along the length of the heater.
- the circuit was turned on and fragrance output was measured at the end of an hour. The liquid fragrance output was about 114mg/hr.
- the air freshening device output of Example 1 correlates with the theoretical calculation of interstitial area of the heater over the wick and a liquid film thickness within the interstices of about 0.04mm (0.0015 inch). This correlation further supports that capillary action is not occurring along the length of the mesh material. In addition, no signs of degradation or melting of the wick was observed.
