AI Technical Summary
Traditional back scrubbers require pre-tying with string or wrapping multiple times with rope, resulting in uneven rotation and slippage, making it difficult to effectively scrub the back, especially inconvenient for the elderly and disabled.
A rotary back scrubbing brush was designed, which adopts a rope winding mechanism including a rope winding disc and a pull rope. The rope winding disc rotates synchronously with the brush disc. Through the rope threading groove and guide groove structure on the rope winding disc, the rope binding step is omitted. The pull rope is wound one turn or less and then pulled alternately to ensure smooth rotation and prevent slippage. The brush disc is equipped with bristles for scrubbing the back.
It achieves a rotating scrubbing brush without the need for binding wires, with high rotational stability and good back scrubbing effect, solving the discomfort problem existing in the prior art, and is suitable for use by the elderly and disabled.
