Patent number: 11564541Abstract: A vacuum cleaner includes a main body and a suction nozzle that suctions up dust on the floor. The suction nozzle includes a housing, a driver, and a rotating brush. The housing includes an entrance through which the dust travels to the main body, a first shaft member, and a first rib disposed along a circumference of the first shaft member. The rotating brush includes a cylindrical body rotated by the first shaft member. The rotating brush also includes a brush member attached to an outer surface of the cylindrical body. The brush member rubs against the floor to direct the dust on the floor towards the entrance. As the brush member rotates, it also comes into contact with the first rib. The brush member includes a plurality of filaments. Some of the filaments are elastically deformed in the direction of the rotation axis upon contacting the first rib.Type: GrantFiled: August 5, 2020Date of Patent: January 31, 2023Assignee: LG ELECTRONICS INC.Inventors: Jung Bae Hwang, Jinrae Cho, Phil Jae Hwang, Chung Jae Ryu

Patent number: 11426042Abstract: A vacuum cleaner includes a main body and a suction nozzle. The suction nozzle includes a connector that defines a passage configured to guide the dust in a first direction to the main body, and a housing that rotatably connects to the connector and defines an inlet configured to transfer the dust to the passage. The connector includes an insertion portion that has a cylindrical shape and is configured to insert into the inlet, a first connection portion spaced apart from the inlet in the first direction, and a coupling part disposed at an outer surface of the insertion portion. The coupling part and the first connection portion are configured to restrict movement of the housing in the first direction, and the inlet is configured to restrict deformation of at least one of the insertion portion or the coupling part.Type: GrantFiled: August 13, 2020Date of Patent: August 30, 2022Assignee: LG ELECTRONICS INC.Inventors: Jung Bae Hwang, Jinrae Cho, Jung Woo Lee, Taekgi Lee, Mi-Jin Kwon

Patent number: 7488362Abstract: A dust collection assembly of a vacuum cleaner is provided. The dust collection assembly includes a dust collecting box, a filter, a flow guide unit, an exhaust guider, and an upper cover. The dust collecting box and the flow guide unit are integrally formed in a single body. The dust collecting box includes a first and second dust collecting spaces for collecting foreign objects. The filter is disposed in the inside of the dust collecting space to primarily filter foreign objects during operation of a cyclone. The flow guide unit guides airflow and has small cyclones integrally formed therein, for secondarily filtering the foreign objects in air. The exhaust guider guides airflow and has a plurality of discharge holes through which air filtered by the small cyclone flows. The upper cover is disposed on the upper side of the exhaust guider.Type: GrantFiled: September 23, 2005Date of Patent: February 10, 2009Assignee: LG Electronics Inc.Inventors: Hoi Kil Jeong, Man Tae Hwang, Young Ho Kim, Jung Bae Hwang, Min Park
