Spraying device and methods

A spraying device comprising:

• a. a frame,
• b. a reservoir assembly, wherein the reservoir assembly is coupled to the frame and comprises a cavity configured to store a liquid;
• c. a piezoelectric atomizer configured to spray atomized liquid particles, wherein the atomized liquid particles are derived from the stored liquid;
• d. a power source, wherein the power source is configured to power the piezoelectric atomizer;
• e. a trigger, wherein the trigger is configured to activate the piezoelectric atomizer;
• f. a magnet, wherein the magnet is configured to magnetically couple the device to a mobile device;
• g. a conduit, wherein the conduit is configured to allow a flow of liquid to the piezoelectric atomizer;
• and
• h. a flow-blocking mechanism comprising a pinch-valve or clamp, coupled to the conduit, wherein the flow-blocking mechanism is configured to occlude the flow of liquid to the piezoelectric atomizer when the trigger is not activating the piezoelectric atomizer;
• or wherein the conduit is self-crimping and configured to occlude the flow of liquid to the piezoelectric atomizer when the trigger is not activating the piezoelectric atomizer.
