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.

Claims (40)

1. 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.

2. The fluid sprayer of claim 1 , wherein the ceiling is formed by the housing.

3. The fluid sprayer of claim 1 , wherein the shelter does not include a floor directly below the battery.

4. The fluid sprayer of claim 1 , wherein the shelter includes a first side rail on a first lateral side of the battery and a second side rail on a second lateral side of the battery such that the battery is disposed directly between the first side rail and the second side rail.

5. The fluid sprayer of claim 1 , wherein the battery extends outside of the battery chamber with the battery mounted to the fluid sprayer.

6. The fluid sprayer of claim 5 , wherein each of an outer side of the battery, the first lateral side of the battery, and the second lateral side of the battery are partially exposed outside of the battery chamber.

7. The fluid sprayer of claim 1 , wherein the battery bay is disposed on a wall formed by the housing.

8. The fluid sprayer of claim 7 , wherein the wall is one of vertical and substantially vertical.

9. The fluid sprayer of claim 7 , wherein the battery does not contact any surfaces defining the battery chamber other than the wall while mounted to the fluid sprayer.

10. The fluid sprayer of claim 7 , wherein the battery bay is formed in a protrusion of the wall, the protrusion projecting from the wall into the battery chamber such that the battery bay is spaced from a base of the wall.

11. The fluid sprayer of claim 1 , wherein the shelter is at least partially formed by a guard piece mounted to the housing, and wherein a guard of the guard piece projects away from the housing such that that guard at least partially encloses portions of the battery chamber.

12. The fluid sprayer of claim 1 , further comprising:

a frame connected to the housing, the frame configured to support the housing relative to a support surface.

13. The fluid sprayer of claim 12 , wherein the frame includes at least one leg.

14. The fluid sprayer of claim 1 , further comprising:

a first handle and a second handle, the first handle and the second handle configured to be grasped during lifting of the fluid sprayer.

15. The fluid sprayer of claim 1 , further comprising:

a spray gun including a trigger configured to control release of the fluid from the spray gun; and

a hose extending between and fluidly connecting the pump and the spray gun.

16. The fluid sprayer of claim 1 , wherein the battery bay is oriented vertically and includes a lower mounting opening such that the battery can enter into the battery bay by vertical movement towards the ceiling and such that the battery can exit from the battery bay by vertical movement away from the ceiling.

17. The fluid sprayer of claim 1 , wherein the battery chamber is not defined by an articulating structure.

18. The fluid sprayer of claim 1 , wherein the pump is at least partially disposed in the housing.

19. 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;

wherein the battery chamber includes a lower opening oriented vertically downward, the lower opening disposed vertically below a bottom side of the battery with the battery mounted to the fluid sprayer;

wherein the battery chamber includes an outer opening oriented longitudinally away from the housing, the outer opening spaced longitudinally outward from an outer side of the battery 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.

20. The fluid sprayer of claim 19 , wherein a ceiling of the shelter is disposed vertically above the battery, the ceiling at least partially defining the battery chamber, and an area of the ceiling defining the battery chamber is greater than an area of the top side of the battery oriented towards the ceiling.
