摘要： An electric vacuum cleaner includes a main body. A hose is connected to the main body. A motor-drive brush is provided in a floor nozzle. An extension pipe connects the floor nozzle and one end of the hose. An electric conductor is located in the extension pipe. The extension pipe includes an outer tube, an inner tube, a first electric connection terminal, a second electric connection terminal, a first conductor casing, and a second conductor casing. The first electric connection terminal is pfovided on one end of the outer tube. The second electric connection terminal is provided on one end of the inner tube. The inner tube slidably extends into the outer tube. The electric conductor is connected between the first electric connection terminal and the second electric connection terminal. The electric conductor is accommodated in the first conductor casing and the second conductor casing. The first conductor casing is provided on the outer tube. The second conductor casing is provided on the inner tube. The outer tube has a dust suction passage. The inner tube has a dust suction passage. The first conductor casing has an interior isolated from the dust suction passage in the outer tube. The second conductor casing has an interior isolated from the dust suction passage in the inner tube.
