Electric power switch for a vacuum cleaner which has a suction control function |
摘要 |
An electric power switch for a vacuum cleaner which is capable of applying an electric voltage to a motor of the vacuum cleaner, capable of controlling a suction force which is established by the motor, is convenient to use, and can be manufactured at a low cost. An air suction passage for introducing an atmospheric air into a handle of the vacuum cleaner extends from a one side wall of a pipe hose toward a cover of the handle in order to communicate with the pipe hose. An operation knob is disposed in a space between the air suction passage and the cover and allows the air suction passage to selectively communicate with an air suction port, which is formed through the cover. A first supporting member for slideably supporting the operation knob extends from a bottom wall of the handle toward the cover up to an upper surface of the air suction passage. A plurality of locking grooves for setting a displacement of the operation knob are formed on an upper surface of the first supporting member. Locking grooves consist of a plurality of on-grooves and an off-groove which are arranged in a row. A second protrusion of the electric power switch selectively engages with the on-grooves and the off-groove in order to set the displacement of the operation knob.
