Patent number: 11419465Abstract: A handheld vacuum cleaner includes a main body with a handle extending along a handle axis. The handheld vacuum cleaner also includes a motor assembly positioned within the main body. The handle axis intersects the motor assembly. The handheld vacuum cleaner also includes a dirty air inlet positioned at a front of the handheld vacuum cleaner and extending along an inlet axis. In addition, the handheld vacuum cleaner includes a cyclonic chamber in fluid communication with the dirty air inlet and the motor assembly. The cyclonic chamber defines a separator axis. The inlet axis and the separator axis intersect to form an acute angle extending between the dirty air inlet and the cyclonic chamber. The inlet axis and the handle axis intersect to form an obtuse angle extending between the dirty air inlet and the handle.Type: GrantFiled: February 27, 2017Date of Patent: August 23, 2022Assignee: Techtronic Floor Care Technology LimitedInventors: Alvin Au Yeuk Yuen, Benson Chun Kit Cheung, Mohammed Irfan, Somnanritha Chan, Yao Xiyin

Patent number: 11363921Abstract: A handheld vacuum cleaner (10), including a main body (22) having a handle (98), a motor assembly (114) positioned within the main body, and a cyclonic separator assembly (26) removably coupled to the main body. The cyclonic separator assembly includes an inlet nozzle (42) having a dirty air inlet (14) positioned in the front of the handheld vacuum cleaner when the cyclonic separator assembly is coupled to the main body, and a cyclonic chamber (30) in fluid communication with the dirty air inlet. The cyclonic chamber defines a separator axis (34). The cyclonic separator assembly further includes a dirt collection region (38) configured to receive debris separated in the cyclonic chamber. The inlet nozzle includes an upstream height (270) measured perpendicular to the inlet axis and a downstream height (274) measured parallel to the separator axis. The downstream height is larger than the upstream height.Type: GrantFiled: February 27, 2017Date of Patent: June 21, 2022Assignee: Techtronic Floor Care Technology LimitedInventors: Alvin Au Yeuk Yuen, Benson Chun Kit Cheung

Publication number: 20190183304Abstract: A handheld vacuum cleaner (10), includes a main body (22), a motor assembly (114) positioned within the main body, and a dirty air inlet (14) positioned at a front of the handheld vacuum cleaner and extending along an inlet axis (46). The handheld vacuum cleaner also includes a cyclonic chamber (30) in fluid communication with the dirty air inlet and the motor assembly. The cyclonic chamber defines a separator axis (34). The inlet axis and the separator axis intersect to form an acute angle (214) extending between the dirty air inlet and the cyclonic chamber. The acute angle is within the range of 20 to 60 degrees such that when the handheld vacuum cleaner is operated in a normal operating condition with the dirty air inlet pointed downwardly the separator axis is oriented vertically.Type: ApplicationFiled: February 27, 2017Publication date: June 20, 2019Inventors: Alvin Au Yeuk YUEN, Benson Chun Kit CHEUNG
