[0055] Core innovation

[0056] 1. Dynamic synthesis technology of multiple fragrance bases: Through the time-division multiplexing of the piezoelectric inkjet array, the millisecond-level fragrance switching (such as the gradual transition from "focus" to "relaxation") is achieved.

[0057] 2. Situational semantic analysis engine: Establish a deep association model of fragrance, scene and emotion (such as automatically enhancing the ratio of cedar and bergamot when identifying the "learning" scene)

[0058] 3. Fractal channel anti-cross-contamination design: Different fragrance bases are independently transported to the mixing chamber through fractal flow channels. The fractal structure + surface energy gradient achieves zero cross-contamination (flavor cross-contamination rate <0.01ppm), ensuring that fragrance base mixing only occurs at the nozzle outlet.

[0059] 4. A spiral micro-electrolytic cell is integrated at the nozzle outlet: it integrates mixing and aging functions, realizes low-power electrochemical modification, and has better fragrance quality than traditional aging, meets the medical safety requirements for long-term wearing of wearable devices, and forms the technical standards for a new generation of smart fragrance systems.

[0060] 5. Expandable liquid storage architecture: supports hot-swap replacement of liquid storage modules, each module contains an RFID tag to record fragrance base information BRIEF DESCRIPTION OF THE DRAWINGS

[0061] Figure 1 : It is a schematic diagram of the principle of the intelligent scene-adaptive perfume electronic device based on piezoelectric inkjet technology of the present invention. It only explains the principle and does not constitute a limitation of the patent. DETAILED DESCRIPTION

[0062] Example 1 (office scene application):

[0063] When the biosensor detects that the user's skin electrical activity decreases by 20%, the emotional perception radar determines that the user is in a fatigue state. The fragrance synthesis engine automatically mixes a compound fragrance of mint (60%), rosemary (30%), and sandalwood (10%). The piezoelectric array releases 0.5mL of fragrance mist at a frequency of 20Hz, and the OLED screen displays a dynamic refreshing animation.

[0064] Embodiment 2 (social scene application):

[0065] The user says "Dating Mode", and the voice recognition module uses NLP analysis to call the preset formula of tuberose (70%) + vanilla (20%) + patchouli (10%). The piezoelectric nozzle sprays the carrier through the mixed aging integrated area to the four-dimensional controlled release carrier to form a fragrance hot zone.

[0066] Example 3 (safe wearing verification):

[0067] The test results after 48 hours of continuous wearing show:

[0068] *No erythema / edema in the neck contact area (assessed according to ICNIRP guidelines)

[0069] *Electrolysis system surface temperature rise ≤ 1.2℃ (detected by thermal imaging camera FLIR E8)

[0070] *Stability retention rate of fragrance base ingredients>99%(GC-MS analysis)

[0071] Embodiment 4 (dynamic fragrance optimization):

[0072] When the user switches from "Meeting" (lemon / cedar scent) to "Dating" (rose / vanilla scent):

[0073] The fractal flow channel transports the degradation enzyme to the nozzle outlet in 0.2 seconds to clean the atomization treatment nozzle, mixing and aging area, and four-dimensional controlled release carrier

[0074] Fractal flow channel completes fragrance base mixing within 0.2 seconds

[0075] Electrolytic cell converts rose aldehyde into rose oxide (for sweetness)

[0076] Controlled-release carrier releases top / base ingredients in a 2:1 ratio

[0077] Electronic nose testing shows that the smoothness of aroma transition is improved by 40%

[0078] Different equipment can also use other suitable aging technologies, such as setting up:

[0079] Aging reaction zone (704): residence time 50-200ms, temperature gradient control (ΔT = 5-15°C)

[0080] Energy Field Processing Area (705): Integration:

[0081] Pulsed electrostatic field (706): field strength 10-30 kV / cm, pulse width 1 μs

[0082] Microwave radiator (707): frequency 2.45 GHz, power density 5 W / cm 3

[0083] Alternatively, ultrasonic microfluidic field coupling technology may be introduced in the aging area; alternatively, the products may be collected and stored directly through pipelines without aging or without passing through a sustained-release system after aging; alternatively, the products may be blown into the air without passing through a sustained-release system after aging through diffusion technologies such as two-fluid atomization, ultrasonic atomization, pump atomization, and hot air.
