Abstract
An improved liquid sprayer having a container (12) with a handle (14). A supply tube (16) extends into the container (12) and upward through a container cap (18) and a container cap attachment (20) and into a pump inlet (22) which is open to a pump (24). Adjacent to the front of pump (24) is a pump outlet (26) and a nozzle (27). Adjacent to the rear of pump (24) is a pump drive (32) which removably communicates with a pump drive socket (34) affixed to a conventional rechargeable drill (36). The drill sprayer (10) can be removably attached to the container (12) which then is refilled and reused. Alternately, the drill sprayer (10) can be permanently affixed to the container (12) and therefore disposable.
Claims20
A fluid sprayer for use with a fluid container that contains a fluid, the fluid sprayer comprising:
- a pump that is secured to the fluid container, the pump having an inlet that is in fluid communication with the fluid container, and a pump drive shaft;
- a motor that drives the pump, the motor having a motor output;
- and
- a first coupler component and a second coupler component that cooperate to provide the sole mechanical coupling between the pump and the motor;
- wherein one of the coupler components is secured to the pump drive shaft and the other coupler component is secured to the motor output, wherein the first coupler component defines a projection and the second coupler component defines a cavity that is sized and shaped to slidingly receive the first coupler component while inhibiting relative rotation between the coupler components when the first coupler component is positioned in the second coupler component.
A combination for spraying a fluid comprising:
- a fluid container that contains a fluid, the fluid container including a handle secured to the side of the fluid container;
- a pump that is secured to the fluid container, the pump having a pump drive shaft;
- a supply tube that connects the pump in fluid communication with the fluid container, wherein the pump withdraws the fluid from the fluid container through the supply tube;
- a nozzle that is secured to the pump, the nozzle being adapted to discharge the fluid that is withdrawn from the fluid container through the supply tube;
- a motor that drives the pump, the motor having a motor output, wherein the handle is for grasping so as to inhibit relative rotational movement between the fluid container and the motor;
- and
- a sliding coupler including a first coupler component and a second coupler component that cooperate to provide the sole mechanical coupling between the pump and the motor;
- wherein one of the coupler components is secured to the pump drive shaft and the other coupler component is secured to the motor output, wherein the first coupler component defines a projection and the second coupler component defines a cavity that is sized and shaped to slidingly receive the first coupler component while inhibiting relative rotation between the coupler components when the first coupler component is positioned in the second coupler component.
A fluid sprayer for use with a fluid container that contains a fluid, the fluid sprayer comprising:
- a pump means that is secured to the fluid container, the pump means having an inlet means that is in fluid communication with the fluid container, and a pump drive means;
- a motor means for driving the pump means, the motor means having a motor output means;
- a sliding coupler means for providing the sole mechanical coupling between the pump means and the motor means, the sliding coupler means including a first coupler component and a second coupler component;
- wherein one of the coupler components is secured to the pump drive means and the other coupler component is secured to the motor output means, wherein the first coupler component defines a projection and the second coupler component defines a cavity that is sized and shaped to slidingly receive the first coupler component while inhibiting relative rotation between the coupler components when the first coupler component is positioned in the second coupler component.
