Patent attributes
A toothbrush with a replaceable head formed to permit ready removal and attachment preferably without the use of a tool. The replaceable toothbrush head may advantageously be formed for coupling with a power toothbrush, particularly, a power toothbrush with a power element that protrudes from the toothbrush head. The replaceable toothbrush head thus preferably is formed to accommodate the power element. In a preferred embodiment, the replaceable toothbrush head is rotated about a rotation axis into engagement with the head of the toothbrush main unit. The replaceable toothbrush head may be moved axially along the rotation axis for alignment with an alignment axis. Preferably, the replaceable toothbrush head is moved axially into engagement with the power element for alignment for coupling with the toothbrush main unit.
