Bending over to dump garbage causes back pain? Why can a vertical broom and dustpan set save 70% of effort?

1. Core design: avoid bending

The handle length of a vertical broom and dustpan set is usually 90-120cm (traditional dustpans are only 30-50cm), so users can complete the cleaning action without bending over, keeping the spine upright and reducing lumbar pressure. Biomechanical verification shows that the lumbar pressure is about 50% of body weight when standing upright, and the pressure increases to 200% of body weight when bending 90°. A labor-saving grip is added to the end of the handle, and a lever system is formed with the elbow joint as the fulcrum. The operating force arm is extended by 3 times, and the force required for cleaning is reduced by more than 60%.

2. Structural optimization: reduce waist force

The bottom of the dustpan adopts a triangular stable structure to lower the center of gravity and prevent rollover; the dust collection bin volume is expanded by 50% (about 1.5-2L), reducing the number of repeated dumping. By comparing the cleaning of the same amount of garbage, the number of times the vertical dustpan bends is only 1/3 of that of the traditional dustpan. The dustpan and broom are locked by a buckle, so you can dump the garbage with one hand, avoiding twisting of the waist when holding with both hands.
