Title:
NEBULIZER SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/018656
Kind Code:
A1
Abstract:
A nebulizer system of the present invention comprises a computer device (400) and a nebulizer head (1) which is directly connected to the computing device (400) by means of a USB cable (200). The computer device (400) supplies a DC voltage (Vbus) through a Vbus line and a GND line of the USB cable (200), and supplies control signals (D+, D-) with a rectangular waveform through a D+ line and D- line of the USB cable (200). The nebulizer head (1) includes: a first resonance circuit which includes a first coil and a first capacitor; a conversion circuit which intermittently or alternately inverts the polarity of the DC voltage (Vbus) in the first resonance circuit, applies the polarity-inverted DC voltage to the first resonance circuit in response to the control signal (D+, D-), and generates an AC voltage with a sinusoidal waveform; and an atomizing unit which is driven by the AC voltage with a sinusoidal waveform, and atomizes and jets liquid.
