Abstract
A dust suction head for use in an electric vacuum cleaner, having an air suction port at the bottom of the head. The head has a brush chamber which accommodates therein a freely rotatable brush having blades that extend along the shaft of the rotational brush. The head additionally has an opening and an air passage connected with the opening for taking in and leading fresh air into the vacuum chamber of the cleaner through the brush chamber such that the fresh air passing through the brush chamber impinges on the blades to accelerate the rotational motion of the blades.
Thus, the head can obtain a necessary amount of air to rotate the brush at all times, especially when it is brushing a carpet, and maintain its smooth motion on the floor while dusting it.
Thus, the head can obtain a necessary amount of air to rotate the brush at all times, especially when it is brushing a carpet, and maintain its smooth motion on the floor while dusting it.
