Abstract
The present invention provides a miniature liquid transfer pump. The pump has a housing that includes first and second blocks joinable to form a leak-resistant impeller chamber with a drive shaft aperture, an inlet and an outlet. An impeller is located in the impeller chamber and a micro-motor with a drive shaft extending therefrom is mounted to the housing. The drive shaft on the micro-motor passes through the drive shaft aperture and engages the impeller. The micro-motor drives the impeller to draw liquid through the inlet and eject the liquid through the outlet.
Claims24
A miniature liquid transfer pump, comprising:
- a housing including first and second substantially rectilinear blocks joinable to form a leak-resistant impeller chamber having a drive shaft aperture, an inlet and an outlet;
- a fluid reservoir coupled to said inlet, said reservoir secured to said housing with a clip;
- an impeller located in said impeller chamber;
- and
- a motor having a drive shaft extending therefrom, that is mounted to said housing such that said drive shaft passes through said drive shaft aperture and engages said impeller to drive said impeller thereby to draw liquid through said inlet and eject said liquid through said outlet.
A method of manufacturing a miniature liquid transfer pump, comprising:
- forming a housing that includes first and second substantially rectilinear blocks joinable to form a leak-resistant impeller chamber having a drive shaft aperture, an inlet and an outlet;
- coupling a fluid reservoir to said inlet and securing said reservoir to said housing with a clip;
- forming an impeller to be located in said impeller chamber;
- and
- providing a motor having a drive shaft extending therefrom, that is mounted to said housing such that said drive shaft passes through said drive shaft aperture and engages said impeller to drive said impeller thereby to draw liquid through said inlet and eject said liquid through said outlet.
For transporting liquid, a liquid transfer device, comprising;
- a pipe having a source end and a destination end;
- and
- a miniature liquid transfer pump coupled to said pipe, said pump, including:
- a housing including first and second substantially rectilinear blocks joinable to form a leak-resistant impeller chamber having a drive shaft aperture, an inlet and an outlet;
- a fluid reservoir coupled to said inlet, said reservoir secured to said housing with a clip;
- an impeller located in said impeller chamber;
- and
- a motor having a drive shaft extending therefrom, that is mounted to said housing such that said drive shaft passes through said drive shaft aperture and engages said impeller to drive said impeller thereby to draw said liquid through said inlet and eject said liquid through said outlet.
