Abstract
An electric vacuum shaver incorporating a vacuum to effectively draw long thin hair into the shearing foil. A space control device is provided so that a vacuum can be better utilized and a proper space can be maintained between the shearing foil and the skin to help long hair to be effectively drawn into the shearing foil without being pressed. The shearing foil and the cutter can be designed in special shapes cooperating with the enclosure to accommodate various hair conditions without adjusting the space between the skin and the shearing foil. Optionally, a disconnecting device is provided to disconnect power to the fan when there is little space between the shearing foil and the skin to prevent the shearing foil from sticking to the skin.
