  • Patent number: 5133372
    Abstract: Hot air hair curling apparatus (1) has a motor-driven hair curler body (2, 2') which is provided with retractable radially arranged teeth (3). The hair curler body (2, 2') is mounted with the apparatus (1) so as to be axially detachable by means of a clutch (4, 5) which can be provided as a catch clutch (5') or as a permanent magnet clutch (5), as desired. The hair curler body (2, 2') is connected with a shaft (24) axially at one end for high mechanical stability, which shaft (24) engages with a first and second bearing (16, 17). The shaft and remaining portion of the hair curler body are hollow and the shaft is provided with elongated throughgoing holes between the bearings so that heated air can flow into the hair curler body. The first bearing is larger than the second bearing which is closest to the motor. Accordingly, it is possible to exchange, clean or disinfect the hair curler body (2, 2') in a simple manner.
