Portable pressurized sprayer

A method for spraying a liquid, the method comprising:

• releasably connecting a housing of an electric pump module to a sprayer tank via a connector on the sprayer tank without transferring liquids from an interior of the sprayer tank to the electric pump module;
• and
• actuating an electric pump positioned within the housing of the electric pump module to pump a gas through a first flow path of the connector into the sprayer tank to increase a pressure within the sprayer tank,
• wherein an automatic switch assembly of the electric pump module monitors an internal pressure of the sprayer tank to determine when the internal pressure exceeds a predetermined limit, and when the internal pressure exceeds the predetermined limit, the automatic switch assembly automatically turns off power to the electric pump, and
• wherein the housing of the electric pump module can be connected or disconnected from the sprayer tank while the sprayer tank is pressurized, and the connector automatically relieves excess pressure from the sprayer tank and automatically resets after normal operating pressure is resumed independent of whether the housing of the electric pump module is connected or disconnected from the sprayer tank.

• wherein the connector automatically relieves excess pressure from the sprayer tank by discharging excess gas through a second flow path comprising an integrated pressure relief valve housed within the connector, the connector automatically resetting after normal operating pressure is resumed, independent of whether the housing of the detachable electric pump module is connected to the sprayer tank or disconnected from the sprayer tank.
