Publication number: 20240349961Abstract: An autonomous vacuum implements a semi-waterproof waste bag capable of collecting dry waste from vacuum debris and liquid waste from mopping. The autonomous vacuum leverages a dual-roller cleaning head, one for dry cleaning and another for wet cleaning. The autonomous vacuum utilizes vacuum force to ingest both dry waste and liquid waste from the cleaning head into the semi-waterproof waste bag. The semi-waterproof waste bag includes a non-permeable portion formed of a waterproof material and a permeable portion formed of an air-permeable material. The semi-waterproof waste bag may further include a water-absorbent material, e.g., water-absorbing spherical beads.Type: ApplicationFiled: April 22, 2024Publication date: October 24, 2024Inventors: Karthik Chandrashekaraiah, Anshuman Kumar, Yu Yang Liu, Shu Yan Liu, Mehul Nariyawala, Navneet Dalal

Publication number: 20100005634Abstract: The elastic clipping structure includes a body unit and an elastic unit. The body unit has a body portion, a clipping portion disposed on a first lateral side of the body portion, and an opening forming on a second lateral side of the body portion. The elastic unit has an elastic body with a U shape. The elastic body is disposed on the body portion, and the elastic body has an abutting portion abutted against the clipping portion and two movable portions passing through the opening. Therefore, the body unit and the elastic unit are mated to each other, so that when two opposite forces are acting on two opposite sides of the elastic unit, the elastic unit is compressed inwards. When the two opposite forces are released from the elastic unit, the elastic unit is restored to its original restriction position by the restriction portion.Type: ApplicationFiled: July 8, 2008Publication date: January 14, 2010Inventors: Cheng-Hsiung Kuo, Yu-Yang Liu, Ming-Chung Huang
