Method and system for switching between packages in a diffusion device based on a liquid level sensor

Abstract

The disclosure herein concerns an atomizing diffusion device including at least two packages with liquid in fluid communication with the atomizing diffusion device, a liquid level sensor that determines the liquid level in the package, and a processor, operatively coupled to the liquid level sensor, for generating a signal indicative of the liquid level and a control instruction for a switch based on the signal, wherein the switch, operatively coupled to the processor, receives the control instruction from the processor, and wherein the control instruction causes the diffusion device to switch from utilizing one package in the diffusion device to utilizing a different package in the diffusion device.

What is claimed is: 
     
         1 . An atomizing diffusion system, comprising:
 at least two packages with liquid in fluid communication with at least one diffuser;   a liquid level sensor that determines the liquid level in at least one of the packages; and   a processor, operatively coupled to the liquid level sensor, for generating a signal indicative of the liquid level and a control instruction for altering a state of the diffusion system;   wherein the liquid level sensor comprises a floating magnet disposed within a track inside at least one of the packages, wherein as a liquid level inside the package changes, the floating magnet moves substantially vertically along the track, and a Hall effect sensor or a Hall effect switch is disposed outside the package at a position to enable sensing the position of the floating magnet in the track.
