AI Technical Summary
Peristaltic pumps used in household appliances, particularly hair styling tools, face issues with hose wear leading to leaks or ruptures, which can cause liquid to spill into electrical components, posing safety risks and device malfunction.
A peristaltic pump design with a chamber containing a deformable tube, equipped with multiple sealing elements and a controlled drainage system to contain and direct liquid flow, ensuring it does not escape into the device, even in the event of a rupture, and a compact layout with angled connectors to minimize size.
The design effectively contains and directs liquid within the pump, preventing contact with electrical components and ensuring safe operation, even when the hose deteriorates, thus enhancing safety and reliability.
