Abstract
A battery powered fluid sprayer includes a shelter that the battery is mounted in to provide power to the electric components of the sprayer. The shelter protects the battery from falling fluid droplets. The shelter extends above the battery and projects outward laterally and longitudinally to protect the battery. The battery can move vertically downward to dismount from the fluid sprayer.

A fluid sprayer configured to be powered by a battery, the fluid sprayer comprising:
- an electric motor;
- a pump operatively connected to the electric motor to be powered by the electric motor;
- a housing within which the electric motor is disposed;
- a battery bay configured to receive the battery when the battery is mounted to the fluid sprayer;
- and
- a shelter defining a battery chamber configured to contain the battery, the shelter fully covering a top side of the battery with the battery mounted to the fluid sprayer to protect the battery from falling spray fluid, the shelter including a ceiling located directly over the battery chamber and at least partially defining the battery chamber, the ceiling extending longitudinally and laterally beyond a top side of the battery with the battery mounted to the fluid sprayer;
- wherein the battery chamber includes a first opening oriented vertically and a second opening oriented longitudinally away from the housing;
- wherein the battery chamber extends vertically below the battery such that a bottom side of the battery is disposed vertically above a lower end of the housing with the battery mounted to the fluid sprayer;
- and
- wherein the shelter is configured such that the shelter at least partially covers a first lateral side of the battery and a second lateral side of the battery with the battery mounted to the fluid sprayer, and the shelter is spaced from the battery with the battery mounted to the fluid sprayer such that air gaps are formed between the shelter and the first lateral side of the battery and between the shelter and the second lateral side of the battery.
