Abstract: A liquid sprayer is provided. This liquid sprayer comprises a bottle having an opening and a sprayer housing attached to the bottle. This sprayer housing includes an electric motor, a voltage source for powering the electric motor, a pump driven by the motor, a switch for completing an electrical circuit, a nozzle mechanism attached to the sprayer housing for spraying a liquid. The liquid sprayer also comprises a venting mechanism. This venting mechanism comprises a vent housing having an inner surface and an outer surface, and a translating piston disposed in the vent housing.

The liquid sprayer also includes a deformable “pinched tube” mechanism which prevents liquid from flowing through the nozzle when the sprayer is not being used. The sprayer housing also includes a trigger movably connected to the sprayer housing for closing the switch, translating the piston and creating a leak-tight seal by squeezing the “pinched tube”.
