AI Technical Summary

Benefits of technology

The invention is a device called a thread and hair cutter blade that is attached to a vacuum cleaner's brush roll. Its purpose is to cut and remove any hair or threads that may damage the bearing, brush roll, or drive belt. The cutter blade is designed to cut the hair and threads into small pieces, which are then sucked back into the vacuum, preventing any long strands from becoming tangled and causing damage. This prevents the need for frequent maintenance and ensures the vacuum works properly.

Problems solved by technology

The problem that creates a need for this invention stems from the brush roller on a vacuum cleaner continually wrapping up human, pet hair and threads from the carpet.
The build up of hair or thread on the axel and bearing eventually freezes the free movement of the bearing resulting in a ceased bearing, burnt up belts, and damaged end caps.
The location of the axel and bearing does not lend itself to an easy home repair and requires a technician and replacement parts.

Embodiment Construction

[0018]The hair and thread cutter blade is a small knife blade mounted in a stationary position to each brush bar end cap. The end cap is used to support the axel bearing of the brush bar and the brush bar axel rotates being driven by the belt from the vacuum cleaners motor or by the air-flow of the vacuum.

[0019]When the brush bar rotates across the surface to be vacuumed it pick up threads, hair and they wrap around the brush bar. On many vacuums a string and hair guard made of felt is glued to the end of the brush bar in order to prevent the hair and thread from moving off the end of the brush bar and wrapping in the axel bearing of the brush bar.

[0020]When hair and thread wrap around the axel and bearing it builds up over time and stops the bearing from turning and many time causes the actual end cap to spin with great resistance resulting in the ceasing the bearing, the melting the belt, or increased resistant preventing the airflow of the vacuum to rotate the brush bar.

Abstract

The hair and thread cutting blade is related to the vacuum cleaner brush roller and cuts hair and thread into tiny pieces as it works its way past the thread guard on the ends of the brush roller preventing them from impeding the rotation of the brush roller.
