1. An electrostatic sprayer apparatus comprising:

  • a main body housing configured to receive a power source;

    a nozzle assembly disposed at a first end of the main body housing;

    a reservoir configured to have a fluid disposed (herein, wherein the reservoir is releasably attachable to the main body housing and is configured for fluid communication with the nozzle assembly when attached to the main body housing, the reservoir comprising;

    a reservoir housing comprising a first linear guide projection and a second linear guide projection, the first linear guide projection and the second linear guide projection disposed in a parallel orientation on a guide surface of the reservoir housing and configured for alignment of the reservoir housing with the main body housing for attachment thereto, the first linear guide projection configured to interact with a first corresponding surface of the main body housing and the second linear guide projection configured to interact with a second corresponding surface of the main body housing;

    an internal cavity defined by an interior surface of the reservoir housing and configured to receive the fluid;

    an opening in the reservoir housing, the opening configured to enable the receiving of the fluid into the internal cavity; and

    a neck defining the opening in the reservoir housing, the neck projecting outwardly from the reservoir housing, wherein each of the first linear guide projection and the second linear guide projection on the guide surface of the reservoir housing is discrete of the neck;

    one or more detachment mechanisms, the one or more detachment mechanisms configured for lockingly attaching the reservoir to the main body housing and releasing the reservoir from the main body housing, wherein at least one of the one or more detachment mechanisms comprises a flange on the main body housing, a complementary structure of the reservoir configured for locking engagement with the flange, and a release structure, the release structure comprising one of a tab or a ring configured to be gripped and pulled by a user for unlocking disengagement of the flange from the complementary structure of the reservoir;

    a pump disposed within the main body housing, the pump configured to be powered by the power source and to pump at least a portion of the fluid from the reservoir to the nozzle assembly for dispensing the electrostatically charged at least portion of the fluid through the nozzle assembly to an exterior of the electrostatic sprayer apparatus;

    an electrostatic module disposed within the main body housing;

    at least one electrode assembly in electrical communication with the electrostatic module via a conductive wire, the at least one electrode assembly configured for electrostatic charging of the at least portion of the fluid; and

    a cap assembly configured to mate with the neck of the reservoir to occlude the opening, the cap assembly further configured to, when the reservoir is attached to the main body housing, form a seal between the reservoir and the pump and enable the fluid communication between the reservoir and the nozzle assembly.
