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 and defines a battery chamber. The battery chamber receives the battery and extends outward relative to the battery such that the battery is covered by the shelter to protect the battery.
Claims20
A paint sprayer for spraying a paint, the paint sprayer comprising:
- a pump comprising a piston, the pump configured to pump the paint;
- a hose that receives the paint output by the pump;
- a gun that receives the paint from the hose, the gun comprising a trigger which, when actuated, causes the gun to spray the paint;
- an electric motor;
- a drive which receives rotational motion from the electric motor and converts the rotational motion to reciprocating motion to reciprocate the piston;
- a battery which supplies power for the electric motor, the battery comprising upward facing surfaces, two opposite lateral surfaces, a front surface, and a bottom surface;
- a battery bay to which the battery mounts for mechanical support and electrical connection and from which the battery dismounts;
- a housing that contains the electric motor;
- and
- a shelter which protects the battery from the paint while exposing the battery to ambient air for cooling and easy access, wherein when the battery is mounted to the battery bay and the sprayer is spraying, the shelter:
- covering from above all of the upward facing surfaces of the battery;
- extends laterally beyond the battery to cover the two opposite lateral surfaces of the battery;
- extends below the battery;
- leaves the front surface of the battery and the bottom surface of the battery exposed;
- and
- extends laterally outward of the battery such that a first air gap is disposed between the shelter a first lateral surface of the two opposite lateral surfaces of the battery, and such that a second air gap is disposed between the shelter and a second lateral surface of the two opposite lateral surfaces of the battery.

A paint sprayer for spraying a paint, the paint sprayer comprising:
- a pump comprising a piston, the pump configured to pump the paint;
- a hose that receives the paint output by the pump;
- a gun that receives the paint from the hose, the gun comprising a trigger which, when actuated, causes the gun to spray the paint;
- an electric motor;
- a drive which receives rotational motion from the electric motor and converts the rotational motion to reciprocating motion to reciprocate the piston;
- a battery which supplies power for the electric motor, the battery comprising upward facing surfaces, two opposite lateral surfaces, a front surface, and a bottom surface;
- a battery bay to which the battery mounts for mechanical support and electrical connection and from which the battery dismounts, wherein the pump is located above the battery and at least part of the electric motor is above the battery when the battery is mounted to the battery bay;
- a housing that contains the electric motor;
- and
- a shelter which protects the battery from paint, the battery located within the shelter when the battery is mounted to the battery bay, the shelter comprising:
- a ceiling located directly above the battery which covers from above all of the upward facing surfaces of the battery when the battery is mounted to the battery bay, the ceiling extending in two opposite directions laterally beyond the battery and further extending longitudinally forward beyond the battery when the battery is mounted to the battery bay, a vertical air gap existing directly between the battery and the ceiling when the battery is mounted to the battery bay;
- and
- a pair of side rails respectively orientated vertically, located on opposite lateral sides of the battery such that the battery is directly between the pair of side rails, and extending above and below the battery, the pair of side rails shielding at least part of each of the two opposite lateral surfaces of the battery laterally from the paint but not contacting the battery to avoid paint from running along the pair of side rails to wick to the battery when the battery is mounted to the battery bay and the sprayer is spraying,
- wherein the shelter does not include a floor directly below the battery when the battery is mounted to the battery bay, and
- wherein the front surface of the battery is exposed when the battery is mounted to the battery bay.

- covers from above an entirety of the top side of the battery;
- extends laterally beyond the battery to cover the two opposite lateral sides of the battery;
- extends below the battery;
- leaves the front side and the bottom side of the battery exposed for access;
- extends outward of the battery such that the two opposite lateral sides do not contact the shelter.
