REMOVER OF DUST FROM THE BOTTOMS OF FOOTWEAR

摘要

A dust remover for footwear using ultrasonic resonance is provided to get rid of dust and foreign substances stained with the footwear at high efficiency and low power consumption, without giving much load to a sole. A dust remover for footwear includes: a piezoelectric element ceramic(11) to generate mechanical vibrations at a rotation-inversion axis mode(13); a drive axis(15) for vibrating at the same pitch with the ceramic; and an oscillation circuit(21). When the drive axis starts vibrating, a dust remover spring(14) vibrates in every direction. A power supply line(18) supplies power to necessary elements. A timer(20) sets an operation time of the dust remover, depending on humidity and wind conditions. Thusly collected dusts are gathered to a dust tray(28).
