6. A chlorine dioxide gas generating device comprising:
a housing having a cavity;
an anode and a cathode each coupled to and disposed within the cavity;
a solution comprising a first reagent and a second reagent disposed within the cavity and configured to generate chlorine dioxide gas out of the solution via electrolysis in a controllable, start and stop manner responsive to an electric current being passed into the anode and the cathode;
a hydrophobic membrane coupled to the housing and configured to allow the chlorine dioxide gas to exit the housing while preventing fluids from flowing therethrough; and
a fluid control apparatus disposed within the cavity and configured to increase a rate of release of the chlorine dioxide gas and diffuse splashing of the solution responsive to the increase in the rate of release of the chlorine dioxide gas,
wherein the fluid control apparatus comprises a bubbler device and a guard member each disposed within the cavity, wherein the bubbler device comprises a body having a plurality of through holes that are configured to increase the rate of release of the chlorine dioxide gas out of the solution, wherein the guard member is configured to diffuse splashing of the solution responsive to the increase in the rate of release of the chlorine dioxide gas by the bubbler device, thereby reducing the amount of the solution pulled into the wall of the hydrophobic membrane, wherein the first reagent is water and the second reagent is sodium chlorite, wherein the housing comprises a lid and a body coupled to the lid, wherein the lid has a first through hole and a second through hole, wherein the chlorine dioxide gas is configured to exit the housing via the first through hole of the lid, wherein, while the chlorine dioxide gas is being generated, the plurality of through holes of the bubbler device are configured to receive additional gas therethrough after the additional gas has entered the housing through the second through hole of the lid, and wherein the lid and/or the body of the housing has at least one groove or protruding detent on an exterior surface thereof in order to mate with a corresponding groove or protruding detent of a housing of a chlorine dioxide gas generating system via a snap-fit mechanism, thereby allowing the first and second through holes to be pressure sealed therebetween.
