<p>The invention relates to a toothbrush consisting of a handle (22) whose neck (28) has a coupling end (30), and of a brush head (24) with a coupling end (32), it being possible for the brush head (24) to be firmly but releasably connected to the handle (22) by engagement of their coupling ends (30, 32). An actuating member (46) is secured movably on the handle (22). A gearing (68, 74) is arranged inside the handle (22). A driving gear (54) is firmly connected to the actuating member (46) and has a driving gear (70). A spindle (76) is mounted axially movably and rotatably in the handle (22). One end of the spindle (76) is connected with rotary movement to the driving gear (70) of the gearing (68, 74) inside the handle (22), and the other end of the spindle (76) is mounted in the coupling end (30) of the handle (22) and has a first part of the device for the releasable connection of the handle (22) to the brush head (24). A second part of the device in the coupling end (32) of the brush head (24) serves for the releasable connection to the first part of the device at the other end of the spindle (76). The brush head can be assembled quickly and clamped firmly, thus providing a hygienically satisfactory connection. <IMAGE></p> |
