Abstract
A clutch device (400) for an upright vacuum cleaner and an upright vacuum cleaner (1) having the same are provided, in which the clutch device (400) is disposed between an electric motor assembly (200) and a machine body assembly (300) of the upright vacuum cleaner (1), and the electric motor assembly (200) includes an electric motor housing (21) and an electric motor (22). The clutch device (400) includes: a sliding track (41d) driven (300) to move by the machine body assembly; a toggling tongue (42d) fixed to the electric motor (22) and rotatable with respect to the electric motor housing (21); and a lever member (43d) having a second end of the lever member (43d) slidably fitted to the sliding track (41d) and a first end fitted with an end of the toggling tongue (42d). When the machine body assembly (300) drives the sliding track (41d) to move, the sliding track (41d) drives the lever member (43d) to rotate, and when the lever member (43d) rotates, the toggling tongue (42d) is stirred to make the electric motor (22) rotate with respect to the electric motor housing (21).
